PART I

Item 1. Business.

Overview

We are a clinical-stage biopharmaceutical company leveraging our proprietary technology platform to design and develop a pipeline of novel oral and respiratory biologic product candidates to treat autoimmune, inflammatory, metabolic, and other diseases. Our proprietary technology platform allows us to exploit existing natural cellular trafficking pathways to facilitate the active transport of diverse therapeutic payloads across epithelial barriers, such as the intestinal epithelium (IE) and the respiratory epithelium (RE). Active transport is an efficient mechanism that uses the cell’s own machinery to transport materials across epithelial barriers. We believe that our ability to exploit this mechanism is a key differentiator of our approach. We currently have two oral biologics in clinical development. Our most advanced product candidate, AMT-101, is in Phase 2 development for patients with ulcerative colitis (UC) and related inflammatory indications. Our second product candidate, AMT-126 is in Phase 1 development for diseases related to IE barrier function defects.

We are developing oral biologic product candidates in patient-friendly dosage forms that are designed for either targeting local gastrointestinal (GI) tissue or entering systemic circulation to precisely address the relevant biology of a disease. We are building a portfolio of oral product candidates based on our technology platform including our most advanced product candidate, AMT-101, a gastrointestinal-selective oral fusion of interleukin 10 (IL-10) and our proprietary carrier molecule that has been designed for active transport across the IE barrier into local gastrointestinal (GI) tissue. IL-10 is a potent immunomodulatory cytokine that is known to be the master regulator of immune homeostasis, including within GI mucosal tissue. While previous clinical trials conducted by others in the field with systemic IL-10 demonstrated efficacy in UC and Crohn’s disease, significant toxicities associated with systemic administration prevented further development. We have designed AMT-101 to cross the IE barrier, but not enter the bloodstream, which we believe may offer significant efficacy and safety benefits compared to systemic IL-10 administration.

As a locally-targeted, GI-selective biologic therapeutic, oral AMT-101 has the potential to be used, as a monotherapy or in combination with other therapeutic agents, in biologic-naïve moderate-to-severe UC patients in addition to UC patients who have failed prior biologic therapy, and in a variety of indications beyond UC. There is a heightened medical need for oral non-systemic, locally-acting immunomodulators that are distinct from systemic immuno-suppressive drugs.

We are conducting a broad Phase 2 clinical program for AMT-101 including our LOMBARD trial as a monotherapy for moderate to severe UC patients, our MARKET trial evaluating the combination of AMT-101 and anti-TNFα therapy in biologic naïve patients with moderately to severely active UC, and our FILLMORE trial as a monotherapy in patients with chronic antibiotic resistant pouchitis. In addition, based on the observation that AMT-101 can impact systemic markers of inflammation, we are conducting our CASTRO trial evaluating the combination of AMT-101 and anti-TNFα therapy in patients with active rheumatoid arthritis (RA) who have had an inadequate response to anti-TNFα monotherapy. Starting with the FILLMORE monotherapy trial in chronic antibiotic resistant pouchitis, we expect to announce top-line data readouts for our AMT-101 FILLMORE and MARKET Phase 2 trials in the first half of 2022. We expect to announce the top-line data readout for our LOMBARD and CASTRO trials in the second half of 2022.

We have observed in preclinical studies, a Phase 1a clinical trial in healthy volunteers, and a Phase 1b clinical trial in patients with UC that oral AMT-101 acts on the local immunological pathways along the GI tissue. In our Phase 1b clinical trial, after 14 days of treatment, UC patients treated with AMT-101 showed trends of improvement in objective disease markers such as fecal calprotectin and histopathologic scores. We also observed that, in addition to impacting local disease markers, AMT-101 was also able to show trends to improvement in systemic markers of inflammation, such as C-reactive protein (CRP).  Importantly, in our Phase 1a clinical trial in healthy volunteers and our Phase 1b clinical trial in patients with UC, no serious adverse events were observed with only negligible levels of AMT-101 detected in systemic circulation.

Our second product candidate, AMT-126, is a GI-selective oral fusion of IL-22 and our proprietary carrier molecule currently in development for diseases related to IE barrier function defects. IL-22 is a cytokine that repairs functional and structural defects of the IE barrier and induces microbial defense. AMT-126 is designed to act locally on the

epithelial cells of the intestinal tissue, thereby repairing the IE barrier and supporting mucosal healing, potentially translating into clinically meaningful improvements in a broad range of GI-focused, peripheral inflammatory and other diseases. While previous clinical trials conducted by others in the field with systemic rhIL-22 demonstrated efficacy in UC, significant toxicities associated with systemic administration have been observed. We have designed AMT-126 to cross the IE barrier, but not enter the bloodstream, which we believe may offer significant efficacy and safety benefits compared to systemic rhIL-22 administration.

We initiated a Phase 1 clinical trial for AMT-126 which includes a Phase 1a single ascending dose in healthy volunteers to be followed by a Phase 1b multiple ascending dose in patients with an indication associated with intestinal barrier defects. We expect to provide an update on the AMT-126 clinical program in the first half of 2022.

We are developing our oral biologic product candidates in patient-friendly dosage forms that are designed for either targeting local tissue or entering systemic circulation to precisely address the relevant biology of a disease. Our technology platform enables us to design and develop various oral biologic therapeutic modalities, such as peptides, proteins, full-length antibodies, antibody fragments, and ribonucleic acid (RNA) therapeutics, with potentially significant advantages over existing marketed and development-stage drugs.

We have expanded our technology platform to also develop local, targeted inhaled biologics. The RE barrier uses natural cellular trafficking pathways similar to the IE barrier, and the cells in the pulmonary lamina propria provide a rich source of novel targets that provide opportunities for us to exploit and target areas of high unmet medical need.

The global biologic therapeutics market has been estimated to be approximately $230.0 billion per year across numerous indications and targets. While our initial focus is on developing novel, oral biologic therapeutics to treat severe autoimmune, inflammatory, and metabolic diseases, any disease that can be treated with a biologic therapeutic is conceivably a candidate for our technology. In many diseases, oral administration of GI-selective biologics may confer inherent advantages over systemic dosing based on the premise that the gut is the primary site of convergence of several core biology axes. At least 70% of the body’s immune system resides in the gut so oral administration provides direct access to key pathways of mucosal immunology. Furthermore, the oral route provides access to the gut-brain and gut-endocrine axes. Our objective is to maximize the value of the technology by continuing to develop a pipeline of novel, differentiated products against well-established and clinically-validated targets in sizable markets where our technology can improve safety and efficacy in addition to offering a patient-friendly oral form.

Our Pipeline and Research Programs

We are leveraging our proprietary technology platform to design and develop a pipeline of oral biologic product candidates with differentiated profiles designed to address autoimmune, inflammatory, metabolic, and other diseases, as shown below. We have expanded our technology platform to also develop local, targeted inhaled biologics that are in early stages of research. We own intellectual property rights to our technology platform and hold worldwide rights to all of our product candidates.

Our Pipeline

AMT-101

AMT-101 is a GI-selective oral fusion of rhIL-10 and our proprietary carrier molecule. We have completed a Phase 1b clinical trial of AMT-101 in UC. IL-10 is an immunomodulatory cytokine that is known to be the master regulator of GI mucosal homeostasis. While previous clinical trials conducted by others in the field with systemic rhIL-10 demonstrated efficacy in Crohn’s disease, significant toxicities associated with systemic administration prevented further development. We have designed AMT-101 to cross the IE barrier while not entering the bloodstream, thereby targeting the drug directly at the site of action of the underlying biology of the disease in the GI tissue and, therefore, potentially avoiding the side effects observed with systemic administration.

In a Phase 1a clinical trial in healthy volunteers, AMT-101 was well tolerated without the previous toxicities typically associated with IL-10 systemic administration. In a Phase 1b clinical trial in patients with UC, after 14 days of treatment, reductions in objective disease markers of intestinal inflammation such as fecal calprotectin and histopathologic scores were observed, suggesting that the patients experienced a rapid clinical response. The localization of AMT-101 in the gut has been further demonstrated in non-human primate (NHP) studies where oral AMT-101 administration was shown to induce a systemic pharmacodynamic response with only negligible levels of AMT-101 detected in systemic circulation.

By design, AMT-101 is actively transported through the IE barrier into the GI tissue, the primary site of inflammation in UC, a disease with approximately 2.2 to 2.4 million patients in the United States and Europe according to a 2014 report. As a locally-targeted, GI-selective biologic therapeutic, oral AMT-101 has the potential to be used in biologic naive, moderate-to-severe UC patients in addition to UC patients who have failed prior biologic therapy, and in a variety of GI indications beyond UC. The U.S. Food and Drug Administration (FDA) has cleared our investigational new drug (IND) application for oral AMT-101 for the treatment of patients with moderate to severely active UC. We

are conducting a broad Phase 2 clinical program for AMT-101 including our LOMBARD trial as a monotherapy for moderate to severe UC patients, our MARKET trial evaluating the combination of AMT-101 and anti-TNFα therapy in biologic naïve patients with moderately to severely active UC, and our FILLMORE trial as a monotherapy in patients with chronic antibiotic resistant pouchitis. In addition, based on the observation that AMT-101 can impact systemic markers of inflammation, we are conducting our CASTRO trial evaluating the combination of AMT-101 and anti-TNFα therapy in patients with active rheumatoid arthritis (RA) who have had an inadequate response to anti-TNFα monotherapy. Starting with the FILLMORE monotherapy trial in chronic antibiotic resistant pouchitis, we expect to announce top-line data readouts for our AMT-101 FILLMORE and MARKET Phase 2 trials in the first half of 2022. We expect to announce the top-line data readout for our LOMBARD and CASTRO trials in the second half of 2022.

AMT-126

AMT-126 is a GI-selective oral fusion of rhIL-22 and our proprietary carrier molecule currently in development for diseases related to IE barrier function defects. IL-22 is a cytokine that repairs functional and structural defects of the IE barrier and induces microbial defense. AMT-126 is designed to act locally on the epithelial cells of the intestinal tissue, thereby repairing the IE barrier and supporting mucosal healing, potentially translating into clinically meaningful improvements in a broad range of GI-focused, peripheral inflammatory and other diseases. We believe that our GI-selective AMT-126 may be safer than systemically administered treatments, because AMT-126 is designed to not enter a patient’s bloodstream, therefore avoiding the potential side effects observed with other previously systemically administered rhIL-22 candidates.

In preclinical development, AMT-126 demonstrated activity in animal models of intestinal inflammation, as well as the induction of markers associated with the repair of IE barrier function defects. The localization of AMT-126 in GI tissue has been further demonstrated in several preclinical studies.  Despite being localized to the GI tissue, we have observed in animal models that AMT-126 can also impact systemic markers of inflammation.

By targeting AMT-126 to the IE barrier, we believe our therapy may translate to clinically meaningful reductions in disease activity. As a locally targeted, GI-selective biologic therapeutic, AMT-126 has the potential to address IE barrier function defects linked to a wide array of diseases, including celiac disease, a disease with no approved therapies, UC, Graft-versus-Host Disease (GVHD), and a number of peripheral diseases secondary to GI dysfunction, such as psoriatic arthritis (PsA) and other spondyloarthropathies (SpA). We initiated a Phase 1 clinical trial for AMT-126 which includes a Phase 1a single ascending dose in healthy volunteers to be followed by a Phase 1b multiple ascending dose in patients with an indication associated with intestinal barrier defects. We expect to provide an update on the AMT-126 clinical program in the first half of 2022.

Research Programs

Our technology platform is enabling the generation of a pipeline of earlier-stage oral product candidates spanning multiple therapeutic areas that can either be targeted to GI tissue or released into blood for broader systemic exposure. While our most advanced product candidates, AMT-101 and AMT-126, are novel, oral biologic therapeutics to treat autoimmune and inflammatory diseases, any disease which can be treated with a biologic therapeutic is conceivably a candidate for our technology. We have expanded our technology platform to also develop local, targeted inhaled biologics that are in early stages of research. Our research programs are focused on expanding into indications with high unmet medical need and sizable potential, including other gastroenterological, metabolic, and respiratory diseases. We believe these programs demonstrate the applicability of our technology platform across a wide range of biological therapeutics and diseases.

We are working on several, and what we believe are promising, research-stage peptides, proteins, and antibodies including: an oral GI-selective construct of glucagon-like peptide 2 (GLP-2) for gastroenterological indications, such as short bowel syndrome (SBS); an oral glucagon-like peptide 1 (GLP-1) for local GI and systemic exposure to treat

metabolic diseases and other disorders; oral antibody constructs for multiple indications; and an oral human growth hormone (hGH) for growth hormone deficiency and related indications.

Our Strategy

Our goal is to transform the biopharmaceuticals landscape by developing novel, targeted oral biologic product candidates that have enhanced efficacy and safety profiles and are more patient-friendly compared to current injection or IV infusion therapies. We believe that our technology platform has the ability to generate products with differentiated product profiles that have significant potential to treat acute and chronic diseases with substantial unmet medical need. We have prioritized our development efforts based on our assessment of the probability of clinical and regulatory success, unmet medical need, and potential market opportunity.

The key tenets of our business strategy to achieve our goal are as follows:

Our Proprietary Oral Biologics Technology Platform

Shortcomings of Current Biologic Therapeutics

Biologic therapeutics provide enormous therapeutic potential because of their high specificity, potency, and ability to target disease-modifying pathways. However, since the IE is a robust natural barrier for the absorption of proteins and peptides, it is difficult to deliver biologic therapeutics orally. Therefore, the systemic, injection or infusion, route is the primary route of administration for biologic therapeutics. The IE barrier represents a significant challenge for drug developers.

The gut is the primary site of convergence of several core biology axes that impact virtually every organ system, including immunological, endocrine and neural. At any given time, over 70% of an individual’s immune system resides in the lamina propria, which is the target-rich tissue of the intestinal tract. However, the currently marketed biologic therapeutics are only able to efficiently access these key biological pathways if the therapeutics are delivered in high doses systemically. Large doses of systemically injected therapeutics could lead to toxicities because they will reach not only the targeted tissue, but also other tissues in the body.

Our Technology Platform for Oral Biologics

We have identified a series of trafficking pathways that are used by microbes to actively transfer proteins across the IE barrier. By leveraging the natural pathways and proteins, we have demonstrated that it is possible to actively transport biologic therapeutics across the IE barrier by oral administration in animals and humans.

Table of Contents

Cholix is a protein secreted by Vibrio cholerae that translocates across the IE barrier of the intestine. We have identified the protein sequences along the cholix molecule responsible for trafficking across the IE barrier and targeting immune cells in the GI tissue. This mechanism is based on active, receptor-mediated processes that naturally transport proteins. Our proprietary technology platform creates a fusion protein containing engineered protein translocation sequences of cholix (the AMT carrier) and any protein of interest, which we refer to as the therapeutic payload, to create a novel biologic that can be transported across the IE barrier. Trafficking across IE cells is an active transport process involving uptake at the luminal surface, movement of vesicles through the cells, and release at the basal surface, that utilize dynamic interactions with endogenous elements of the cell.

Figure 2 illustrates the distinction between our proprietary active transport approach and that of traditional passive diffusion approaches.

Figure 3 illustrates our ability to leverage the translocation mechanism of cholix and either actively target the biologic therapeutics to the GI tissue or enter into systemic circulation to precisely address the relevant biology of a disease.

Advantages of our Technology Platform

Our technology platform establishes a new paradigm to orally deliver biologic therapeutics. We believe that AMT-101 has demonstrated clinical proof of concept for our technology platform by enabling the active transport and rapid absorption of an orally-administered biologic therapeutic. We believe that our technology offers several advantages:

10

Table of Contents

Beyond the active transport capabilities of our proprietary technology platform, we also utilize several other technologies to ensure our products are protected in the GI environment and released at the appropriate location of the intestine. We have employed enteric coating techniques using off the shelf polymers and excipients that are considered safe for use by regulatory authorities. Our product candidates can be released at various points in the intestine for optimal uptake such as at the terminal ileum, which is part of the small bowel, or along the colon. In a scintigraphy trial in human subjects, we evaluated the release profile of various formulations using capsules of our enteric-coated formulations where we used a radiolabeled tracer instead of active drug product. As shown in Figure 4, the formulated capsule remained intact until it reached the terminal ileum, where it began to dissolve and release its contents. We have developed other formulations that allow our product candidates to be released at various other regions along the GI tract.

The outlined regions in the two images to the left (2.3 and 2.5 hours) represent the stomach, whereas the outlined regions in the two images to the right (3.5 and 5.5 hours) represent the colon. This demonstrates in the clinic our ability to target drug to a desired location along the GI tract.

Our ability to deliver biologic therapeutics with our oral technology platform provides several potential advantages over systemically administered biologics and oral products that are also GI-selective. These attributes are designed to achieve the following benefits:

Our Product Candidates: AMT-101 and AMT-126

We have leveraged our proprietary technology platform to design and develop a pipeline of oral biologic product candidates with differentiated profiles designed to address autoimmune, inflammatory, metabolic, and other diseases. AMT-101 is a GI-selective oral fusion of rhIL-10 that has completed a Phase 1b clinical trial in UC patients and is currently being evaluated in Phase 2 clinical trials in UC and related inflammatory indications. AMT-126 is a GI-selective oral fusion of rhIL-22 that is currently in a Phase 1 clinical trial for diseases arising from IE barrier function defects. We have initiated a Phase 1 clinical trial for AMT-126 similar to that which we conducted with AMT-101 including a Phase 1a single ascending dose in healthy volunteers to be followed by a Phase 1b multiple ascending dose in healthy patients with an indication associated with intestinal barrier defects.

AMT-101: Our Oral GI-Selective IL-10 Fusion Protein

Our most advanced product candidate, AMT-101, is a recombinant fusion of rhIL-10 and the engineered protein translocation sequences of cholix. We have initiated and dosed patients in our LOMBARD Phase 2 clinical trial as a monotherapy for moderate to severe UC patients. In addition, since AMT-101 is a non-systemic, non-immunosuppressive immunomodulator, we believe AMT-101 could provide benefit when used in combination with existing marketed products to improve clinical response and induction of clinical remission. We have initiated and dosed the MARKET Phase 2 clinical trial evaluating the combination of AMT-101 and anti-TNFα therapy in patients with moderately to severely active UC.  We have also initiated and dosed patients in the FILLMORE Phase 2 clinical trial as a monotherapy in patients with chronic antibiotic resistant pouchitis. Finally, based on the observation that AMT-101 can impact systemic markers of inflammation, we have initiated and dosed patients in the CASTRO Phase 2 clinical trial evaluating the combination of AMT-101 and anti-TNFα therapy in patients with active RA who have had an inadequate response to anti-TNFα monotherapy. Oral AMT-101 is designed to act locally in the intestinal lamina propria tissue to modulate immune pathways along GI tissue and control inflammation, resulting in clinical and symptomatic improvement. We believe oral AMT-101 may have safety advantages compared to systemically administered IBD treatments, including prior clinical evaluation of rhIL-10, because AMT-101 is designed to not enter a patient’s bloodstream. Targeted localization of AMT-101 to the GI tissue lamina propria is expected to translate into clinically meaningful reductions in inflammation and disease activity. We plan to initially develop AMT-101 to treat UC and other IBD indications such as chronic antibiotic resistant pouchitis and Crohn’s disease, as well as peripheral inflammatory indications such as RA. Figure 5 below shows the molecular structure of AMT-101.

Figure 5. Molecular Structure of AMT-101

Overview of IL-10 Biology

IL-10 is a potent immunomodulatory cytokine that is known to be the master regulator of GI mucosal tissue immune homeostasis. IL-10 regulates the activation and effector function of multiple innate and adaptive immune cells and upregulates cytokine inhibitors (e.g., soluble TNF-receptor and IL-1Ra). The binding of IL-10 to its receptor activates the IL-10/JAK1/STAT3 cascade, a key pathway in modulating inflammation, where phosphorylated STAT3 homodimers translocate to the nucleus to activate the expression of target genes to promote cellular protection, survival, and proliferation.

Preclinical and Translational Science Support for Treatment of IBD with IL-10

Support for the use of rhIL-10 in the treatment of IBD has been reinforced by the studies in IL-10 knockout mice in which the absence of IL-10 leads to spontaneous signs of intestinal inflammation as early as three weeks of age. The symptoms progress into chronic transmural inflammation of the large and small bowels that resemble Crohn’s disease, which can be alleviated with IL-10 treatment.

IL-10 has been identified in human genome wide-association studies as being associated with risk factors for IBD, further demonstrating the genetic contribution to disease pathogenesis. Moreover, polymorphisms in the IL-10 receptor and loss-of-function mutations in IL-10 or the IL-10 receptor are associated with early onset of disease for UC and Crohn’s disease, respectively.

Clinical Support for Treatment of IBD with IL-10

rhIL-10 has been evaluated as a systemically administered agent in clinical trials in healthy volunteers and patients with IBD. Prior clinical trials with rhIL-10 in Crohn’s disease demonstrated a trend towards clinical improvement. However, systemically administered rhIL-10 treatment was associated with adverse events and loss of response at higher doses. Certain clinical trials exhibited induction of severe anemia and thrombocytopenia believed to have been caused by broad systemic exposure of rhIL-10. In addition to the observed toxicities, systemically administered rhIL-10 is thought to have resulted in intestinal IL-10 concentrations that were insufficient to down-regulate inflammation. We believe that IL-10 targeted to the local site of inflammation may offer optimal therapeutic benefit and avoid the safety issues observed in systemic administration.

Potential Benefits and Positioning of AMT-101, Our IL-10 Program

We believe AMT-101 has the potential to offer clinical benefits in GI diseases, as well as in peripheral inflammatory indications such as RA. We have initially developed AMT-101 for UC and will further explore the potential clinical benefits of AMT-101 for other GI diseases. Within UC, AMT-101 has the potential to be used in biologic naive, moderate-to-severe UC patients in addition to UC patients who have failed prior biologic therapy, and in a variety of GI indications beyond UC. We have initiated a broad Phase 2 program for AMT-101 including having dosed patients in a Phase 2 clinical trial as a monotherapy in moderate to severe UC patients as a combination therapy to approved anti-TNFα monoclonal antibody therapies in biologic-naïve patients with moderate to severe UC, as a monotherapy for chronic antibiotic resistant pouchitis, and an orphan GI inflammatory disease with no approved therapies.

IL-10 is a potent immunomodulator that has shown preliminary efficacy in Crohn’s disease patients when administered systemically, though with serious adverse events caused by the systemic exposure of rhIL-10. Oral AMT-101 has the potential to unlock the full therapeutic potential of rhIL-10 therapy because it is actively transported to immunomodulatory pathways in the local GI tissue and is designed to not enter a patient’s bloodstream, so it is not expected to have the safety issues of previous systemic rhIL-10 therapies.

Due to its potentially attractive safety profile and immunomodulatory mechanism, AMT-101 has an opportunity to potentially be used as a single agent or in combination with other therapies for IBD and other inflammatory diseases. Furthermore, we have initiated a Phase 2 clinical study in patients with RA as the evidence of immunomodulatory effects observed in the peripheral circulation in our Phase 1 clinical trial in healthy volunteers and patients with active UC suggests that AMT-101 has the potential to be used beyond GI disorders in peripheral inflammatory indications.

AMT-101 is formulated to be available in a convenient, oral, once-a-day tablet.

Market Opportunity—Ulcerative Colitis

UC is a chronic inflammatory condition that causes mucosal inflammation of the colon. It affects the entire colon and is characterized by relapses and remissions. UC affects an estimated 700,000 to 900,000 people in the United States and up to 1.5 million people in Europe according to a 2014 report.

Symptoms and Diagnosis

UC is diagnosed based on clinical, laboratory, endoscopy, and histopathology findings. Symptoms are dependent upon the extent and severity of the disease and can include bloody diarrhea, rectal bleeding, urgency, fecal incontinence, and fatigue. As remission is achieved, rectal bleeding disappears, stools normalize, and signs of active inflammation are no longer observed on endoscopy. The current treatment strategy for UC depends on the severity, distribution, and pattern of disease.

Standard of Care and Unmet Medical Needs and Opportunities

Mesalamine is used for first-line treatment and maintenance of remission in mild or moderately active UC and is supplemented with oral corticosteroids for disease flares. Patients who are moderate to severe or refractory to mesalamine and oral corticosteroids may be treated with IV steroids, or biologics, including anti-TNF, anti-integrin a4b7, anti-IL-23, or small molecule inhibitors of JAK.

Despite multiple therapeutic options, clinical management of UC remains unsatisfactory. Approximately half of UC patients will relapse in any given year and, based on current clinical trial outcomes, greater than 80% of moderate to severe patients do not remain in remission after one year of biologic therapy. As a result of the loss of biologic response, there are a considerable number of patients on anti-TNFα therapy who are considered partial responders but not yet prepared to switch to a new agent. These patients would be candidates for add-on therapy with an additional, safe agent, with the goal to return them to remission while still on anti-TNFα therapy. While there have been considerable advances in the understanding of UC, significant unmet medical need remains and current therapies remain limited, due to inadequate clinical response/remission, loss of response, tolerability, speed of action, and lack of oral options.

Market Opportunity—Chronic Antibiotic Resistant Pouchitis

In patients who have had a colectomy for refractory UC disease, ileal pouch-anal anastomosis (IPAA) is a common procedure to create a pouch for patients’ stool. Patients who have an IPAA typically have four to eight bowel movements per day, but the most common complication among patients who have undergone an IPAA is pouchitis, an idiopathic chronic inflammatory condition. It is estimated that approximately 50-60% of patients who have undergone IPAA surgery for UC will develop at least one episode of pouchitis in the next decade. Pouchitis leads to increased stool frequency and liquidity, cramping, urgency, fecal incontinence, and occasional rectal bleeding. It has been estimated that approximately 30,000 to 45,000 patients have pouchitis in the United States.

While the majority of patients with acute pouchitis respond well to a short course of antibiotics, some patients develop chronic and refractory disease that requires long-term non-antibiotic therapy. Currently, there are no therapies approved for pouchitis and chronic refractory patients will be treated with budesonide, anti-inflammatory drugs (mesalamine, sulfasalazine), or immunosuppressive drugs (other steroids or anti-TNFα). There is a significant unmet medical need to develop products for patients who develop severe chronic antibiotic resistant pouchitis.

Summary of Our AMT-101 Data

AMT-101 has completed a Phase 1b clinical trial in UC patients. We have observed in preclinical studies, a Phase 1a clinical trial in healthy volunteers, and a Phase 1b clinical trial in patients with UC that oral AMT-101 acts on the local immunological pathways along the GI tissue. Importantly, AMT-101 did not enter the bloodstream and no serious adverse events were observed. We believe that AMT-101 has demonstrated PoC for our technology platform by enabling the active transport and rapid absorption of an orally-administered biologic therapeutic.

Summary of Our AMT-101 Preclinical Data

AMT-101 Demonstrates In Vivo Active Transport and Localization

We examined the localization of AMT-101 in the intestine in a rat model by immunofluorescence microscopy which demonstrated that AMT-101 successfully transported across the IE barrier and localized along the GI tissue in vivo. Figure 6 shows a representative image of the cross-section of an intestinal villus. Each of the components (human IL-

10 and cholix carrier) was observed separately and their co-localization in the GI tissue is evidenced in the composite image.

Figure 6. In vivo localization of AMT-101 in GI lamina propria tissue

The transport of AMT-101 (yellow label) across an IE cell was visualized by the co-localization of IL-10 (green label) and cholix-based carrier (red label). Cell nuclei were labeled in blue. AMT-101 was seen to transport efficiently and localize within the immune-rich lamina propria of the intestinal tissue. We believe the ability to locally access and target the immune cells on the other side of the IE barrier drives the immunomodulatory response to IL-10.

In Vivo Pharmacology: AMT-101 Demonstrates Efficacy in a Murine Model of UC

We have observed that oral AMT-101 treatment in an oxazolone-induced murine model of chronic UC improved colonic histopathology in vivo. As shown in Figure 7, colonic tissue architecture as observed in histological staining in oral AMT-101 treated animals at day seven resembled that of healthy, non-inflamed tissue whereas the placebo treated group did not demonstrate any benefit. Furthermore, treatment with AMT-101 also showed significant improvement in objective measures of local disease including colon weight, colon weight/length ratio, and histopathology severity score.

Local GI-selective AMT-101 Induces Systemic Anti-Inflammatory Activity

In an oxazolone-induced murine model of chronic UC, treatment with oral AMT-101 resulted in a consistent trend of reduced levels of pro-inflammatory markers in systemic circulation as measured in the blood, as shown in Figure 8. The decrease in levels of these markers is consistent with our hypothesis that AMT-101 can induce a broad immunomodulatory response including effects that are consistent with IL-10 biology. These initial efficacy data support AMT-101’s potential to correct systemic immune dysregulation and inflammation by targeting the local immunological pathways along the GI tissue.

Figure 8. Oral GI-selective AMT-101 decreased systemic markers of inflammation and immune dysregulation

In addition to IL-17A, IL-6, and MIP1a, oral GI-selective AMT-101 resulted in broadly and systemically decreased markers of inflammation, including: IL-1ß, IL-4, IL-13, IL-15/15R, IL-28, GCSF, LIX, and MCSF.

We also investigated AMT-101 dosing in NHP. As shown in Figure 9, we observed higher ratios of colonic tissue pSTAT3/STAT3 at all doses, demonstrating colonic STAT3 activation following AMT-101 treatment. The colonic STAT3 activation observed in our studies is an indicator of IL-10 receptor activation and demonstrates AMT-101 target engagement. In addition to activation of pSTAT3, IL-10 receptor engagement can also be measured by systemic levels of IL-1Ra, a well-established anti-inflammatory protein, as IL-10 stimulates the downstream production of IL-1Ra. As shown in Figure 10, the induction of systemic IL-1Ra in NHPs demonstrates that AMT-101 not only replicates IL-10 function in the gut but also produces a systemic immunomodulatory effect with negligible levels of AMT-101 detected in blood.

 Oral AMT-101 Generates Robust Systemic Pharmacodynamic Response with Negligible Systemic Exposure

AMT-101 was administered by oral capsules, subcutaneous (SC) injection, and IV infusion in a non-disease NHP model. Despite greater than 1,000-fold lower levels of systemic IL-10 observed in blood via oral administration, systemic levels of induced IL-1Ra by oral AMT-101 were equivalent to, if not even slightly greater than, systemic levels of IL-Ra induced by SC injection and IV infusion (Figure 11). This effect demonstrates the ability of oral GI-selective AMT-101 to induce immunomodulatory effects along GI tissue that impact both local and systemic biology, but without meaningful systemic exposure. We believe oral AMT-101 will have the same, if not greater, efficacy as systemic IL-10, but will not exhibit the toxicity and safety issues posed by high levels of systemic IL-10 exposure. Furthermore, induction of IL-1Ra is indicative of the immunomodulatory potential of local IL-10 and we believe suggests a broader role for oral GI-selective AMT-101 in peripheral inflammatory and autoimmune indications.

Summary of Our AMT-101 Clinical Data

AMT-101 Phase 1a/b Clinical Trials

We designed the Phase 1a portion of our Phase 1a/b clinical trial to assess the safety, tolerability, and pharmacokinetics of increasing single ascending doses (SAD) of oral AMT-101 in healthy volunteers. In the Phase 1b portion of the trial, we sought to gather early data on the safety, tolerability, pharmacokinetics, pharmacodynamics, and initial clinical response following a multiple ascending dose (MAD) of AMT-101 in adult patients with active UC over 14 days of treatment. The results of the Phase 1b clinical trial are intended to inform the design and dose selection of future PoC trials.

Other objectives of the Phase 1a/b clinical trial were to: (i) assess the incidence of anti-drug antibodies against AMT-101; (ii) evaluate potential pharmacodynamic markers of AMT-101 in plasma and tissue; and (iii) assess clinical activity of AMT-101 after two weeks of daily treatment in patients with active UC.

Phase 1a Clinical Trial Design

As shown in Figure 12, the Phase 1a clinical trial consisted of a SAD escalation in six cohorts of healthy volunteers. At each dose level, six subjects were randomized 4:2 to receive AMT-101 or a single dose of placebo. The doses tested were 1 mg, 3 mg, 10 mg, 30 mg, 60 mg, and 120 mg.

Preliminary Phase 1a Data Has Demonstrated the Tolerability of Oral AMT-101 Treatment

The results of the Phase 1a clinical trial demonstrated that oral AMT-101 was observed to be well tolerated by healthy volunteers. In Figure 13 below, shows that a total of three treatment-emergent adverse events (TEAEs) were observed—one in the twelve placebo patients, and two out of the total of twenty-four active AMT-101 patients. All adverse events were mild and self-limiting.

Results of the pharmacokinetic analyses from all doses (1-120 mg) confirmed that AMT-101 was GI-selective as it was not detected in the blood.

Phase 1b Clinical Trial Design

As shown in Figure 14, the Phase 1b clinical trial consisted of a MAD escalation in adult patients with evidence of active UC (as assessed by stool frequency and rectal bleeding) and moderate severity in nature. A total of four cohorts

19

Table of Contents

were dosed with either 1 mg, 3 mg, 10 mg, or 30 mg AMT-101, randomized 3:1 to receive AMT-101 or a placebo administered once daily for fourteen days. The goal of the trial was to assess the safety of AMT-101 and any change in UC disease activity, through endoscopy, histology, biomarkers, and serum samples. Stool samples and colonic biopsies were obtained both at baseline and at day 14 of treatment to assess fecal calprotectin as well as histology based upon blinded central read of the Geboes scoring system. Fecal calprotectin is an objective and well-established marker of clinical response in UC studies and the Geboes scoring system is a standard measure of histological response which uses a 0-22-point histologic scoring system in which higher scores represent more severe disease.

Phase 1b Data Has Demonstrated that Oral AMT-101 is Well Tolerated

The results of the Phase 1b clinical trial demonstrated that oral AMT-101 was observed to be well tolerated by patients with UC. Figure 15 below, shows that a total of 23 TEAEs were observed including three in the four placebo patients, and 20 in the 12 active AMT-101 patients. The adverse events of the Phase 1b clinical trial included nasopharyngitis and adverse events associated with underlying UC symptoms such as abdominal pain, diarrhea, and nausea. All adverse events were self-limiting and mild to moderate, with no adverse events warranting early discontinuation of treatment. Importantly, unlike what was observed in previous clinical trials studying systemically delivered IL-10, no treatment emergent AEs of anemia or thrombocytopenia were observed. Systemic levels of AMT-101 were either undetectable or <1 ng/mL, thereby confirming gut-selectivity.

Figure 15: AMT-101 was well tolerated in active UC patients after 14 days of treatment with no meaningful differences in TEAEs observed among active subjects and placebo

Results of Clinical Response

Fecal calprotectin (FCP) is a well-established clinical marker of disease activity in patients with UC. FCP values greater than 150 µg/g correlate with active inflammation. As can be seen in Figure 16, dosing of 1 mg and 3 mg AMT-101 led to placebo-adjusted mean reductions of FCP of 44% and 27% after 14 days of dosing in UC patients with baseline FCP>150 µg/g. Previous clinical trials with systemically delivered IL-10 showed a diminution of activity at higher doses, which is also observed at higher doses of AMT-101. In addition, we presented at the European Crohn’s and Colitis Organization 2021 Congress (ECCO ’21) (Posch, M. et al) that microbiome analyses demonstrate enhancement of favorable enteric commensal bacteria, known to be correlated with restoration of intestinal immune homeostasis in this Phase 1b clinical trial.

CRP is a well-established biomarker of systemic inflammation. At 1 mg, 3 mg, and 30 mgs, greater reductions in CRP levels were observed in UC patients with baseline CRP greater than 5mg/L when compared to placebo. By design, AMT-101 is a GI-selective protein and was not detected in systemic circulation. However, reduction in CRP levels suggests that treating UC patients with oral GI-selective AMT-101 resulted in local intestinal as well as systemic immunomodulatory activity, the latter of which indicates the potential to treat peripheral inflammatory indications.

histologic ulcerations and erosions. When each component is added, the total score can range from 0 (normal) to 22 (severe inflammation and tissue destruction). To assess activity of AMT-101 on the GI mucosa, colonic biopsies were obtained at baseline and then after 14 days of dosing and Geboes scores were assessed by a blinded, central read GI pathologist. Patients that had valuable Day 0 and Day 14 biopsies were assessed by the central reader.

In Figure 18, AMT-101 reduced Geboes scores in 60% (6/10) active AMT-101 patients when compared to 0% (0/2) placebo patients.

Figure 19 shows pre-dose and post-treatment histological images from a UC patient in our Phase 1b clinical trial dosed with 10 mg of AMT-101 in which the Geboes score improved from a score of 15 to a score of three using a 22-point scale, with higher scores indicating more severe disease activity. The pre-dose image reveals the UC patient had crypt destruction and an inflammatory infiltrate in their colon at baseline which are resolved in the post-treatment image after 14 days of treatment with AMT-101.

AMT-101 Phase 2 Clinical Program

We have completed the Phase 1b clinical trial for AMT-101 in UC and analyzed additional data to assess safety and inform dose selection for Phase 2 clinical trials across multiple indications. We have initiated and dosed patients in our LOMBARD Phase 2 clinical trial as a monotherapy for moderate to severe UC patients. In addition, since AMT-101 is a non-systemic, non-immunosuppressive immunomodulator, we believe AMT-101 could provide benefit when used in combination with existing marketed products to improve clinical response and induction of clinical remission. Therefore, we have initiated and dosed the MARKET Phase 2 clinical trial evaluating the combination of AMT-101 and anti-TNFα therapy in patients with moderately to severely active UC. We have also initiated and dosed patients in the FILLMORE Phase 2 clinical trial as a monotherapy in patients with chronic antibiotic resistant pouchitis. Finally, based on the observation that AMT-101 can impact systemic markers of inflammation, we have initiated and dosed patients in the CASTRO Phase 2 clinical trial evaluating the combination of AMT-101 and anti-TNFα therapy in patients with active RA who have had an inadequate response to anti-TNFα monotherapy. Starting with the FILLMORE monotherapy trial in chronic antibiotic resistant pouchitis, we expect to announce top-line data readouts for our AMT-101 FILLMORE and MARKET Phase 2 trials in the first half of 2022. We expect to announce the top-line data readout for our LOMBARD and CASTRO trials in the second half of 2022.

Figure 20 presents the plan for Phase 2 clinical trials for AMT-101. The Company has increased total enrollment from 30 patients to between 40 and 50 patients due to an imbalance in the trial’s planned 1:1 randomization for the Phase 2 MARKET combination trial of oral AMT-101 with anti-TNFα in moderate-to-severe ulcerative colitis patients. The trial has been and continues to be blinded.

AMT-126: Our Oral GI-Selective IL-22 Fusion Protein

Our second product candidate, AMT-126, is a GI-selective oral fusion of rhIL-22 and our proprietary carrier molecule currently in development for diseases related to GI tissue barrier function defects. IL-22 is a cytokine that repairs functional and structural defects of the IE barrier and induces microbial defense. AMT-126 is designed to act locally on the epithelial cells of the intestinal tissue, thereby repairing the IE barrier and supporting mucosal healing, potentially translating into clinically meaningful improvements in a broad range of GI-focused, peripheral inflammatory and other diseases. We believe AMT-126 may have safety advantages relative to systemically administered IBD treatments, including prior clinical evaluation of rhIL-22, because AMT-101 is designed to stay in the GI tissue and not enter a patient’s bloodstream.

In preclinical development, AMT-126 demonstrated activity in animal models of intestinal inflammation, as well as induction of local tissue and systemic effects associated with the repair of IE barrier function defects. The localization of AMT-126 in GI tissue has been further demonstrated in NHP studies. As a locally targeted, GI-selective biologic therapeutic, AMT-126 has the potential to address IE barrier function defects linked to a wide array of diseases, including celiac disease, a disease with no approved medicines, UC, and a number of peripheral diseases secondary to GI dysfunction, such as psoriatic arthritis (PsA) and other spondyloarthropathies (SpA). We have initiated a Phase 1 clinical trial for AMT-126 similar to that which we conducted with AMT-101 including a Phase 1a single ascending dose in healthy volunteers to be followed by a Phase 1b multiple ascending dose in healthy patients with an indication associated with intestinal barrier defects.

Figure 21 shows the molecular structure of AMT-126.

Figure 21. Molecular structure of AMT-126

The Role of IL-22 Biology in IE Barrier Function Defect Correction

IL-22 is a cytokine that repairs functional and structural defects of the IE barrier and induces microbial defense by counteracting inflammasome-driven IE barrier function defects. IL-22 also functions to promote cell proliferation, block apoptosis, and support wound healing. While IL-22 can have a variety of actions on the structural and functional properties of the intestine, the most critical action related to health and disease relates to maintenance of the IE barrier. For example, in celiac disease, gliadin-induced IE barrier function defects of the small intestine appear to be correlated with a reduction of IL-22 in a NHP model. In addition, depletion of IL-22-producing CD4⁺ cells is correlated with active disease in UC models.

Potential Benefits of AMT-126, Our IL-22 Program

We believe AMT-126 may have a profile that will make it compelling to develop for IE barrier function defects linked to a wide array of diseases including celiac disease, UC and others. IL-22 has a mechanism of action that is directed at disturbances in the IE barrier function, which is central to these diseases. There are currently no approved therapies focused on the repair of IE barrier function.

We have designed AMT-126 to act locally on the GI tissue while avoiding entering the patient’s bloodstream, which we believe will mitigate previously reported adverse effects associated with systemic IL-22 treatments.

Due to its potentially attractive safety profile and complementary mechanism of action with those of anti-inflammatory products, we believe AMT-126 has the potential to be used as a single agent or in combination with anti-inflammatory products.

AMT-126 will be formulated to be available in a convenient, once daily, oral dosage form.

Summary of Our AMT-126 Preclinical Data

AMT-126 Shows Highly Comparable Bioactivity to rhIL-22 in Established Models of In Vitro Pharmacology

AMT-126 was evaluated to determine in vitro bioactivity. As shown in Figure 22, IL-22 receptor dimerization and STAT3 activation confirmed ligand-dependent activation of the IL-22 signaling pathway that was highly comparable to multiple sources of rhIL-22. Furthermore, the AMT carrier by itself demonstrated no bioactivity.

Oral AMT-126 Shows Efficacy in a Murine Dextran Sulphate Sodium (DSS) Induced Model of UC

In a murine DSS-induced UC model to assess the activity of oral AMT-126, oral dosing of AMT-126 reduced DSS-induced weight loss and fecal hemoccult, and improved stool consistency during the course of the trial.

Figure 23. Oral AMT-126 demonstrated efficacy in a murine model of disease (DSS)

Oral AMT-126 Shows Systemic Pharmacological Effects with Low Systemic Exposures

AMT-126 was administered by oral capsules in a non-disease NHP model and, by design, showed minimal (pg/ml) levels in the systemic circulation.  Although AMT-126 is intended to stay in the GI tissue, we observed systemic induction of Reg3A and IL-1Ra (Figure 24). This effect demonstrates the ability of oral GI-selective AMT-126 to induce effects along GI tissue that impact both local and systemic biology, but without meaningful systemic exposure. We believe oral AMT-126, as a gut selective therapy, could have the same, if not greater, efficacy as systemic IL-22, but may also have an enhanced safety profile due to minimal systemic levels of IL-22. Furthermore, the systemic induction of IL-1Ra suggests a broader role for oral GI-selective AMT-126 in peripheral diseases secondary to GI dysfunction.

AMT-126 Phase 1 Clinical Programs

We initiated a Phase 1 clinical trial for AMT-126 which includes a Phase 1a single ascending dose in healthy volunteers to be followed by a Phase 1b multiple ascending dose in patients with an indication associated with intestinal barrier defects. We expect to provide an update on the AMT-126 clinical program in the first half of 2022.

Research Programs

While our most advanced product candidates focus on developing novel, oral biologic therapeutics to treat autoimmune and inflammatory indications, any disease which can be treated with a biologic therapeutic is conceivably a candidate for our technology. Our research programs are focused on expanding into indications with high unmet medical need and sizable market potential, including other gastroenterological and metabolic diseases. We have expanded our technology platform to also develop local, targeted inhaled biologics that are in early stages of research. We believe these programs demonstrate the applicability of our technology platform across a wide range of biological therapeutics and diseases.

Immunology and Inflammation

Currently, AMT-101 and AMT-126 are our most advanced product candidates in autoimmune and inflammatory indications; however, we have started additional programs based on several other biologic therapeutics including full length antibodies. We are also expanding our capabilities in applying our proprietary carrier technology to broad antibody engineering formats, including Fab and scFv constructs, where antagonist strategies are required.

Gastroenterology

The ability to selectively target proteins or peptide therapeutics to the intestinal tract makes gastroenterology a logical therapeutic area of interest for application of our product candidates and allows us to access biological pathways beyond immunology and inflammation. Our first research candidate is an oral GI-selective GLP-2 receptor agonist that is being designed to treat patients with SBS. Current treatment paradigms for patients with SBS include total parenteral nutrition and daily injections of GLP-2 analog peptide. There are several weekly-administered GLP-2 analog products in development, but none are focused on oral delivery. Our technology platform would allow the direct targeting of GLP-2 receptors located in the intestinal tissue with minimal systemic exposure. Our research programs may also develop product candidates with potential in other gastroenterology applications such as motility and neuro-gastroenterology.

Metabolic Diseases and Other Disorders

The intestinal tissue is a main site of action for multiple incretin peptides, such as GLP-1, gastric inhibitory peptide, and glucagon, which are core components of pathways involved in diabetes and obesity. Currently, the vast majority of these molecules are administered to patients via systemic injection. We believe that oral delivery of these molecules directly to the sites of incretin receptors expression along the GI tissue and in the hepatic portal system will allow us to improve upon standard of care by more favorably affecting metabolic pathways, including those that regulate

29

Table of Contents

glycemic function, minimize systemic exposures, and impact other linked pathologies, particularly if our product candidates also lower body fat levels. We are exploring diabetes, obesity, and possibly Non-alcoholic Steatohepatitis for our oral GLP-1 analog research program.

We have also conducted research on metabolic diseases caused by growth hormone deficiency. Our research program in this area is an oral hGH. The primary site of action of hGH is in the liver, where it induces production of insulin-like growth factor-1. By virtue of our platform, our hGH program is targeted to the hepatic portal system and reaches the intended organ target (liver) prior to any systemic exposure. Similar to GLP-1 and GLP-2 analogs, there are several injectable hGH products in development; however, our oral hGH may uniquely minimize systemic exposure, reach the liver target more efficiently, and improve compliance.

Respiratory

We have expanded our technology platform to also develop targeted inhaled biologics localized to the respiratory tract. The RE barrier uses natural cellular trafficking pathways similar to the IE barrier, and the cells in the pulmonary lamina propria provide a rich source of novel targets that provide opportunities for us to exploit and target areas of high unmet medical need.  AMT’s respCarrier system is a distinct carrier from our oral (cholix based) system that leverages natural trafficking pathway evolutionarily optimized for respiratory epithelium.  The potential applications for biologic therapeutics targeted to the respiratory system are vast and include multiple indications associated with respiratory immunology, barrier function and other mechanisms.  The extension of our platform enables complementary orthogonal strategies to target another important organ system, further building on our deep and rapidly expanding capabilities in mucosal immunology. With local targeting in both the GI and respiratory tracts, we are able to apply a broad and holistic approach to leveraging mucosal immunology at multiple locations in the body to treat and correct immune dysregulation.  We will continue to explore high value opportunities to develop therapeutic product candidates in this area.

Manufacturing

We believe that developing our own manufacturing capacity and capability is important to limit our reliance on contract manufacturers, protect our trade secrets and intellectual property, and improve our manufacturing processes.  We have spent and continue to spend significant resources developing our current manufacturing processes, capabilities, and know-how. We are currently commissioning and qualifying a new GMP manufacturing facility located in South San Francisco where we will continue to manufacture clinical drug supply. We have successfully manufactured clinical supply at our previous GMP facility also located in South San Francisco. We will also continue

31

Table of Contents

to rely on third-party current good manufacturing practice (cGMP) manufacturers for certain manufacturing steps of our product candidates for clinical supply.  We have established non-exclusive relationships with several contract manufacturers, for the manufacturing of various intermediates and finished product candidates. We have personnel with significant technical, manufacturing, analytical, quality, regulatory, cGMP, and project management experience to execute our internal manufacturing capabilities, oversee our third-party manufacturers, and to manage manufacturing and quality data and information for regulatory compliance purposes.

Commercialization Plan

We do not currently have any approved drugs and we do not expect to have any approved drugs in the near term. Therefore, we have no sales, marketing, or commercial product distribution capabilities and have no experience as a company in marketing drugs. When, and if any of our product candidates are approved for commercialization, we intend to develop a commercialization infrastructure for those products in the United States, Europe, Asia, and potentially in certain other key markets. We may also rely on partnerships to provide commercialization infrastructure, including sales and marketing and commercial distribution.

Competition

The pharmaceutical and biotechnology industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on intellectual property. We face potential competition from many different sources, including major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical companies, universities and other academic institutions, government agencies, and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for the research, development, manufacturing, and commercialization of therapies aimed at treating autoimmune, inflammatory, metabolic, and other diseases. Any product candidates that we successfully develop and commercialize will compete with current therapies and new therapies that may become available in the future.

In particular, with respect to our most advanced product candidates, AMT-101 and AMT-126, we compete against companies that produce injectable biologic therapeutics such as AbbVie Inc., Eli Lilly and Co., Janssen Pharmaceuticals, Inc., Roche Holding Ltd. and Takeda Pharmaceutical Company Ltd., as well as companies that produce oral products such as Abivax SA, Arena Pharmaceuticals, Inc., Bristol-Myers Squibb Co., Galapagos NV, Gilead Sciences, Inc., Gossamer Bio, Inc., Landos Biopharma, Inc., Pfizer Inc., Protagonist Therapeutics, Inc. and Theravance Biopharma, Inc.

We are not aware of any other company or organization that has developed a FDA-approved oral biologic, other than peptides. However, we are aware of other companies developing oral biologic drug candidates using their own technology platform.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals, and marketing approved drugs than we do. Mergers and acquisitions in the pharmaceutical, biotechnology and diagnostic industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and enrolling subjects for our clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

We could see a reduction or elimination of our commercial opportunity if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we or our collaborators may develop, including if competitors develop a safer and/or more effective oral biologic technology platform. Our competitors also may obtain FDA or foreign regulatory approval for their products more rapidly than we may obtain approval for product candidates, which could result in our competitors establishing a strong market position before we or our collaborators are able to enter the market. The key competitive factors affecting the success of all our product candidates, if approved, are likely to be their efficacy, safety,

32

Table of Contents

convenience, price, the effectiveness of companion diagnostics, if required, the level of biosimilar or generic competition and the availability of reimbursement from government and other third-party payors.

Intellectual Property

Our success depends in part on our ability to obtain and maintain proprietary protection for our product candidates, technology and know-how, to operate without infringing the proprietary rights of others and to prevent others from infringing our proprietary rights. Our strategy is to seek to protect our proprietary position by, among other methods, pursuing and obtaining patent protection in the United States and in jurisdictions outside of the United States related to our proprietary technology, inventions, improvements, and product candidates that are important to the development and implementation of our business. Our patent portfolio is intended to cover our product candidates and related components, their methods of use and processes for their manufacture, and any other inventions that are commercially important to our business. We also rely on trademarks as well as trade secret protection of our confidential information and know-how relating to our proprietary technology platform, and product candidates. We believe that we have substantial know-how and trade secrets relating to our technology and product candidates.

As of January 28, 2022, our patent portfolio includes patents and patent applications related to our technology platform and our product candidates. In total, our patent portfolio includes 63 U.S. and foreign issued patents and over 94 other pending patent applications. Foreign patents are granted in the following jurisdictions: Europe (validated in Germany, France, United Kingdom, Belgium, Switzerland, Spain, Ireland, Italy, Netherlands, Sweden, Norway, Austria, Denmark, Finland, Hungary, Poland, Portugal, Turkey, Czech Republic, Luxembourg, and Slovenia), Canada, China, Israel, Australia, Japan, South Korea, Mexico, Russia, South Africa, and India. The technology platform filings include 60 issued patents and at least 56 pending applications. Certain platform filings are expected to expire as early as 2031. Other filings directed to platform technology are expected to expire as early as 2039.

In addition to platform filings, we have filings directed to specific product candidates. For our product candidates, we generally pursue multilayered patent protection covering the composition of matter including the sequence of the product candidates, the formulations of the product candidates, and/or the functional characteristics of the product candidates. In addition to composition of matter coverage, we also generally pursue claims directed to methods of making, and methods of use of the product candidates. Filings specific to AMT-101 and AMT-126 are expected to expire in 2040 or 2039.

Government Regulation

The FDA and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring and post-approval reporting of biologics such as those we are developing. We, along with third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory authorities of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates.

U.S. Biologics Regulation

The process required by the FDA before biologic product candidates may be marketed in the United States generally involves the following:

Preclinical and Clinical Development

Prior to beginning the first clinical trial with a product candidate, we must submit an IND to the FDA. An IND is a request for authorization from the FDA to administer an investigational new drug product to humans. The central focus of an IND submission is on the general investigational plan and the protocol or protocols for preclinical studies and clinical trials. The IND also includes results of animal and in vitro studies assessing the toxicology, pharmacokinetics, pharmacology and pharmacodynamic characteristics of the product, chemistry, manufacturing and controls information, and any available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day period, raises safety concerns or questions about the proposed clinical trial. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with cGCP, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trial, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. Furthermore, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site and must monitor the trial until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some studies also include oversight by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board, which provides authorization for whether or not a trial may move forward at designated check points based on access to certain data from the trial and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing preclinical studies and clinical trials and clinical trial results to public registries.

For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap.

34

Table of Contents

In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more information about the product. These so-called Phase 4 trials may be made a condition to approval of the BLA. Concurrent with clinical trials, companies may complete additional animal studies and develop additional information about the biological characteristics of the product candidate and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, must develop methods for testing the identity, strength, quality, purity, and potency of the final product. Additionally, appropriate packaging must be selected and tested. Stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

As a result of the COVID-19 public health emergency, we may be required to develop and implement additional clinical trial policies and procedures designed to help protect subjects from the COVID-19 virus. For example, in March 2020, the FDA issued a guidance, which the FDA subsequently updated, on conducting clinical trials during the pandemic, which describes a number of considerations for sponsors of clinical trials impacted by the pandemic. The FDA has also published other COVID-19-related industry guidance, including updates to previous guidance, regarding Good Manufacturing Practices, remote interactive evaluations of drug manufacturing and bioresearch monitoring facilities, and drug product manufacturing and supply chain inspections, among others. The ultimate impact of the COVID-19 pandemic on our business operations is highly uncertain and subject to change and will depend on future developments, including new regulatory requirements and changes to existing regulations.

BLA Submission and Review

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, preclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must include all relevant data available from pertinent preclinical studies and clinical trials, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls, and proposed labeling, among other things. The submission of a BLA requires payment of a substantial application user fee to the FDA, unless a waiver or exemption applies.

Once a BLA has been submitted, the FDA’s goal is to review standard applications within ten months after it accepts the application for filing, or, if the application qualifies for priority review, six months after the FDA accepts the application for filing. In both standard and priority reviews, the review process is often significantly extended by FDA requests for additional information or clarification. The FDA reviews a BLA to determine, among other things, whether a product is safe, pure, and potent and the facility in which it is manufactured, processed, packed or held meets standards designed to assure the product’s continued safety, purity and potency. The FDA may convene an advisory committee to provide clinical insight on application review questions. Before approving a BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure compliance with cGCP. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

35

Table of Contents

After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced, the FDA may issue an approval letter or a Complete Response letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A Complete Response letter will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the Complete Response letter without first conducting required inspections, testing submitted product lots and/or reviewing proposed labeling. In issuing the Complete Response letter, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product.

If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the BLA with a Risk Evaluation and Mitigation Strategy (REMS) to ensure the benefits of the product outweigh its risks. A REMS is a safety strategy to manage a known or potential serious risk associated with a product and to enable patients to have continued access to such medicines by managing their safe use, and could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may require one or more Phase 4 post-market trials and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization and may limit further marketing of the product based on the results of these post-marketing studies.

Expedited Development and Review Programs

The FDA offers a number of expedited development and review programs for qualifying product candidates. The fast track program is intended to expedite or facilitate the process for reviewing new products that meet certain criteria. Specifically, new products are eligible for fast track designation if they are intended to treat patients with a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. Fast track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a fast track product has opportunities for frequent interactions with the review team during product development and, once a BLA is submitted, the product may be eligible for priority review. A fast track product may also be eligible for rolling review, where the FDA may consider for review sections of the BLA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the BLA, the FDA agrees to accept sections of the BLA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the BLA.

A product intended to treat patients with a serious or life-threatening disease or condition may also be eligible for breakthrough therapy designation to expedite its development and review. A product can receive breakthrough therapy designation if preliminary clinical evidence indicates that the product, alone or in combination with one or more other drugs or biologics, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all of the fast track program features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the development and review of the product, including involvement of senior managers.

Any marketing application for a biologic submitted to the FDA for approval, including a product with a fast track designation and/or breakthrough therapy designation, may be eligible for other types of FDA programs intended to expedite the FDA review and approval process, such as priority review and accelerated approval. A product is eligible for priority review if it has the potential to provide a significant improvement in the treatment, diagnosis or prevention of a serious disease or condition. For original BLAs, priority review designation means the FDA’s goal is to take action on the marketing application within six months of the 60-day filing date (as compared to ten months under standard review).

36

Table of Contents

Additionally, products studied for their safety and effectiveness in treating patients with serious or life-threatening diseases or conditions may receive accelerated approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of accelerated approval, the FDA will generally require the sponsor to perform adequate and well-controlled post-marketing clinical trials to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product.

Fast track designation, breakthrough therapy designation, priority review and RMAT designation do not change the standards for approval but may expedite the development or approval process. Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat patients with a rare disease or condition, which is a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States for which there is no reasonable expectation that the cost of developing and making available in the United States a drug or biologic for this type of disease or condition will be recovered from sales in the United States for that drug or biologic. Orphan drug designation must be requested before submitting a BLA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. The orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review or approval process.

If a product that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusive approval (or exclusivity), which means that the FDA may not approve any other applications, including a full BLA, to market the same biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the BLA application fee.

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

Post-approval Requirements

Any products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to cGMP, quality controls, record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing user fee requirements, under which the FDA assesses an annual program fee for each product identified in an approved BLA. Biologic manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and

37

Table of Contents

correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. A company can make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising, potential civil and criminal penalties, government investigation, and/or debarment or exclusion from participation in federal health care programs. Physicians may prescribe legally available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the practice of medicine by physicians or their choice of treatments. The FDA does, however, regulate manufacturer’s communications on the subject of off-label use of their products.

Biosimilars and Reference Product Exclusivity

The ACA includes a subtitle called the BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-approved reference biological product. To date, a number of biosimilars have been licensed under the BPCIA, and numerous biosimilars have been approved in Europe. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars.

Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and potency and that the biological product is highly similar to the reference product notwithstanding minor differences in clinically inactive components, which can be demonstrated through comparative analytical studies, animal studies, and a clinical trial or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient or that it can be substituted for the reference product without the intervention of a health care provider who prescribed the reference product, and, for products that

38

Table of Contents

are administered multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. Complexities associated with the larger, and often more complex, structures of biological products, as well as the processes by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by the FDA.

Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing that applicant’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of its product. The BPCIA also created certain exclusivity periods for biosimilars approved as interchangeable products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be readily substituted by pharmacies, which are governed by state pharmacy law.

The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact and implementation of the BPCIA are subject to significant uncertainty.

Other Healthcare Laws and Compliance Requirements

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which they conduct their business. Such laws include, without limitation: the federal Anti-Kickback Statute, the federal False Claims Act, the Sunshine Act, the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, and similar foreign, federal and state fraud and abuse, transparency, and health information privacy and security laws.

The federal Anti-Kickback Statute prohibits, among other things, persons and entities from knowingly and willfully soliciting, receiving, offering or paying remuneration, to induce, or in return for, either the referral of an individual, or the purchase or recommendation of an item or service for which payment may be made under any federal healthcare program. The term remuneration has been interpreted broadly to include anything of value, including stock options. The federal Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers and formulary managers, among others, on the other. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, but they are drawn narrowly and require strict compliance in order to offer protection. Our activities, including our engagement of consultants, may be alleged to be intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of an applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all relevant facts and circumstances. Our practices may not in all cases meet all of the criteria for protection under a statutory exception or regulatory safe harbor. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, a claim including items or services resulting from a violation of the federal Anti-Kickback Statute, can result in a false or fraudulent claim for purposes of the federal False Claims Act.

Civil and criminal false claims laws, including the federal False Claims Act, which can be enforced through civil whistleblower or qui tam actions, and civil monetary penalty laws prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment to the federal government, including federal healthcare programs, that are false or fraudulent. For example, the federal False Claims Act prohibits any person or entity from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government. A claim includes “any request or demand” for money or property presented to the U.S. government. Pharmaceutical and other healthcare companies have been prosecuted under these laws for, among other things, allegedly providing free products or other illegal kickbacks to customers to induce

39

Table of Contents

customers to refer or use the companies’ products over competitors’ products or alternative treatments that were billed to federal healthcare programs for reimbursement for the products.

The U.S. federal Physician Payments Sunshine Act requires applicable manufacturers of covered prescription drugs, devices, biologics or medical supplies subject to FDA approval or clearance for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to annually report to the Centers for Medicare & Medicaid Services (CMS) information related to certain payments and other transfers of value made in the previous year to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain non-physician healthcare professionals (such as physician assistants and nurse practitioners, among others), teaching hospitals, and information regarding ownership and investment interests held by physicians and their immediate family members.

HIPAA created additional federal criminal statutes that prohibit, among other things, executing a scheme to defraud any healthcare benefit program, including private third-party payors, and making false statements relating to healthcare matters. In addition, HIPAA, as amended the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their implementing regulations, impose certain requirements on HIPAA covered entities, which include certain healthcare providers, healthcare clearinghouses, and health plans, as well as individuals and entities, known as business associates, that provide services for or on behalf of the covered entities that involve individually identifiable health information, relating to the privacy, security, and transmission of individually identifiable health information.

We are also subject to additional similar U.S. state and foreign law equivalents of each of the above federal laws, which, in some cases, differ from each other in significant ways, and may not have the same effect, thus complicating compliance efforts. For example, we may be subject to state and foreign anti-kickback and false claims laws that may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third party payors, including private insurers, or that apply regardless of payor; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government; state and local laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; state laws that require the reporting of information related to drug pricing; state and local laws requiring the registration of pharmaceutical sales representatives; and state and foreign laws governing the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

In the event of any actual or alleged failure to comply with any of these or other laws or regulations, we may face investigations and other proceedings by governmental authorities and claims and litigation by private parties in certain circumstances.  If our operations are found to be in violation of any of such laws or any other governmental regulations that apply, or if we settle any claims or proceedings relating to any such laws or regulations, we may be subject to fines, penalties or other liabilities, including, without limitation, significant civil, criminal and administrative penalties, damages, fines, exclusion from participating in government-funded healthcare programs, such as Medicare and Medicaid or similar programs in other countries or jurisdictions, government investigations, consent decrees, corporate integrity agreements, integrity oversight and reporting obligations to resolve allegations of non-compliance, disgorgement, imprisonment, contractual damages, reputational harm, diminished profits and market share, and the curtailment or restructuring of our operations.

Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any pharmaceutical or biological product for which we obtain regulatory approval. Sales of any product, if approved, depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state, and foreign government healthcare programs, commercial insurance and managed healthcare organizations, and the level of reimbursement, if any, for such product by third-party payors. Decisions regarding whether to cover any of our product candidates, if approved, the extent of coverage and amount of reimbursement to be provided are made on a plan-by-plan basis. Further, no uniform policy for coverage and reimbursement exists in the United States, and coverage and reimbursement can differ significantly from payor to payor. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage policy, formulary, and reimbursement rates, but also have their own methods and approval process

40

Table of Contents

apart from Medicare determinations. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific, clinical, and/or cost-effectiveness support for the use of our product candidates to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.

For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization.

In addition, the U.S. government, state legislatures, and foreign governments have continued implementing cost-containment programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic products. Third-party payors are increasingly challenging the prices charged for medical products and services, examining the medical necessity and reviewing the cost effectiveness of pharmaceutical or biological products, medical devices and medical services, in addition to questioning safety and efficacy. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product that receives approval. Decreases in third-party reimbursement for any product or a decision by a third-party not to cover a product could reduce physician usage and patient demand for the product.

Healthcare Reform

The United States and some foreign jurisdictions are considering or have enacted a number of reform proposals to change the healthcare system. There is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by federal and state legislative initiatives, including those designed to limit the pricing, coverage, and reimbursement of pharmaceutical and biopharmaceutical products, especially under government-funded health care programs, and increased governmental control of drug pricing.

The ACA, which was enacted in March 2010, substantially changed the way healthcare is financed by both governmental and private insurers in the United States, and significantly affected the pharmaceutical industry. The ACA contains a number of provisions of particular import to the pharmaceutical and biotechnology industries, including, but not limited to, those governing enrollment in federal healthcare programs, a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, a new licensure framework for follow on biologic products, and annual fees based on pharmaceutical companies’ share of sales to federal health care programs. There have been executive, legislative and judicial challenges to certain aspects of the ACA since its enactment. For example, the Tax Cuts and Jobs Act of 2017 (Tax Act) was enacted, which, among other things, removed penalties for not complying with ACA’s individual mandate to carry health insurance, effective January 1, 2019. On December 14, 2018, a Texas District Court Judge ruled that the individual mandate is a critical and inseverable feature of the ACA, and therefore, because it was repealed as part of the Tax Act, the remaining provisions of the ACA are invalid as well. However, in June 2021 the U.S. Supreme Court held that Texas and other challengers had no legal standing to challenge the ACA, dismissing the case on procedural grounds without specifically ruling on the constitutionality of the ACA. Thus, the ACA will remain in effect in its current form. It is possible that the ACA will be subject to judicial or Congressional challenges in the future. It is unclear how future challenges to the ACA and healthcare measures promulgated by the Biden administration will impact the ACA, our business, financial condition and results of operations.

On January 28, 2021, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructs certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. Complying with any new legislation or reversing changes implemented under the ACA could be time-intensive and expensive, resulting in a material adverse effect on our business.

41

Table of Contents

Other legislative changes have been proposed and adopted since the ACA was enacted, including aggregate reductions of Medicare payments to providers of 2% per fiscal year and reduced payments to several types of Medicare providers. These reductions went into effect in April 2013 and will remain in effect through 2031, with the exception of a temporary suspension implemented under various COVID-19 relief legislation from May 1, 2020 through March 31, 2022, unless additional action is taken by Congress. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester.

Moreover, there has recently been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. At the federal level, in 2020, under the Trump administration, the U.S. Department of Health and Human Services (HHS) and CMS issued various rules in November and December of 2020 that were expected to impact, among others, price reductions from pharmaceutical manufacturers to plan sponsors under Part D, fee arrangements between pharmacy benefit managers and manufacturers, manufacturer price reporting requirements under the Medicaid Drug Rebate Program, including regulations that affect manufacturer-sponsored patient assistance programs subject to pharmacy benefit manager accumulator programs and Best Price reporting related to certain value-based purchasing arrangements. Multiple lawsuits have been brought against the HHS challenging various aspects of the rules implemented during the Trump administration. As a result, the Biden administration and HHS have delayed the implementation or published rules rescinding some of these Trump-era policies.

Under the American Rescue Plan Act of 2021, effective January 1, 2024, the statutory cap on Medicaid Drug Rebate Program rebates that manufacturers pay to state Medicaid programs will be eliminated. Elimination of this cap may require pharmaceutical manufacturers to pay more in rebates than it receives on the sale of products, which could have a material impact on our business. In addition, Congress is considering legislation that, if passed, could have significant impact on prices of prescription drugs covered by Medicare, including limitations on drug price increases and allowing Medicare to negotiate pricing for certain covered drug products. The impact of these regulations and any future healthcare measures and agency rules implemented by the Biden administration on us and the pharmaceutical industry as a whole is currently unknown. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our product candidates if approved.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, a number of states are considering or have recently enacted state drug price transparency and reporting laws that could substantially increase our compliance burdens and expose us to greater liability under such state laws once we begin commercialization after obtaining regulatory approval for any of our products.

Risks Related to Our Business, Financial Condition, and Capital Requirements

We are early in our development efforts, have a limited operating history and have no products approved for commercial sale, which makes it difficult to evaluate our current business and predict our future success and viability.

We are an early clinical-stage biopharmaceutical company with a limited operating history upon which you can evaluate our business and prospects.

We have no products approved for commercial sale and have not generated any revenue from product sales. We are developing a novel technology platform which is an unproven and highly uncertain undertaking and involves a substantial degree of risk. While we are conducting Phase 2 clinical trials for our most advanced product candidate, AMT-101, a GI-selective oral fusion of IL-10 and our proprietary carrier molecule, and are conducting a Phase 1 clinical trial of AMT-126, a GI-selective oral fusion of IL-22 and our proprietary carrier molecule, we have not initiated clinical trials for any of our other product candidates. To date, we have not obtained marketing approval for any product candidates, manufactured a commercial scale product or arranged for a third-party to do so on our behalf, or conducted sales and marketing activities necessary for successful product commercialization. Our limited operating history as a company makes any assessment of our future success and viability subject to significant uncertainty.

We will incur expenses and encounter difficulties, complications, delays, and other known and unknown factors and risks frequently experienced by early-stage biopharmaceutical companies in rapidly evolving fields, and we have not yet demonstrated an ability to successfully overcome such risks and difficulties. We also may need to transition from a company with a research and development focus to a company capable of supporting commercial activities. We have not yet demonstrated an ability to successfully overcome such risks and difficulties, or to make such a transition. If we do not adequately address these risks and difficulties or successfully make such a transition, our business will suffer.

We have incurred significant net losses in each period since inception, and we expect to continue to incur net losses for the foreseeable future.

We have incurred net losses in each reporting period since our inception, including net losses of $100.3 million for the year ended December 31, 2021 and $66.6 million for the year ended December 31, 2020. As of December 31, 2021, we had an accumulated deficit of $239.6 million.

We have invested significant financial resources in research and development activities, including for our preclinical and clinical product candidates. We have not generated any revenue from product sales to date and we do not expect to generate revenue from product sales for several years, if at all. The amount of our future net losses will depend, in part, on the level of our future expenditures and revenue. Moreover, our net losses may fluctuate significantly from quarter to quarter and year to year, such that a period-to-period comparison of our results of operations may not be a good indication of our future performance.

We expect to continue to incur significant expenses and increasingly higher operating losses for the foreseeable future. We anticipate that our expenses will increase substantially if and as we:

45

Table of Contents

Our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity, working capital, and our ability to fund our development efforts and achieve and maintain profitability. In any particular period, our operating results could be below the expectations of securities analysts or investors, which could cause our stock price to decline.

We have historically financed our operations primarily through private placements of our convertible preferred stock and the sale of common stock in public equity issuances, such as our IPO in June 2020 and our follow-on equity offering in April 2021. In addition, on January 27, 2022, the Company entered into a Sales Agreement with SVB Leerink LLC and JMP Securities LLC, as the Company’s sales agents (Agents), pursuant to which the Company may offer and sell from time to time through the Agents up to $150 million in shares of the Company’s common stock through an “at-the-market” program. We may seek to raise capital through debt financings, private or public convertible debt financings, private or public equity financings, license agreements, collaborative agreements or other arrangements with other companies, or other sources of financing. There can be no assurance that such financing will be available or will be at terms acceptable to us. If adequate funds are not available, we may be required to reduce operating expenses, delay or reduce the scope of our development efforts, obtain funds through arrangements with others that may require us to relinquish rights to certain of our technologies or products that we would otherwise seek to develop or commercialize ourselves, or cease operations.

Developing biologic therapeutics is a highly uncertain undertaking and involves a substantial degree of risk.

We have no products approved for commercial sale. To obtain revenue from the sales of our products that are significant or large enough to achieve profitability, we must succeed, either alone or with third parties, in developing, obtaining regulatory approval for, manufacturing, and marketing approved products with significant commercial success. Our ability to generate revenue and achieve profitability depends on many factors, including:

46

Table of Contents

Because of the numerous risks and uncertainties associated with developing biologic therapeutics, we are unable to predict the timing or amount of our expenses, or when we will be able to generate any meaningful revenue or achieve or maintain profitability, if ever. In addition, our expenses could increase beyond our current expectations if we are required by the FDA or foreign regulatory authorities, to perform studies in addition to those that we currently anticipate, or if there are any delays in any of our clinical trials or the development of any of our product candidates. Even if one or more of our product candidates is approved for commercial sale, we anticipate incurring significant costs associated with launching and commercializing any approved product candidate and ongoing compliance efforts.

We will need to obtain substantial additional capital to finance our operations. A failure to obtain this necessary capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce, or terminate our research and drug development programs, future commercialization efforts, product development, or other operations.

Developing biologic therapeutics, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive, and uncertain process that takes years to complete. Our operations have required substantial amounts of cash since inception, and we expect our expenses to increase significantly in the foreseeable future. To date, we have financed our operations primarily through the sale of equity securities. Developing our product candidates and conducting clinical trials for the treatment of autoimmune, inflammatory, metabolic, and other diseases will require substantial amounts of capital. We will also require a significant amount of capital to commercialize any approved products. Even if one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring significant costs associated with sales, marketing, manufacturing and distribution activities. Furthermore, other unanticipated costs may also arise.

As of December 31, 2021, we had cash, cash equivalents, and investments of $159.8 million. In April 2021, we also issued common stock in a follow-on public offering which resulted in net proceeds of $112.8 million after deducting the underwriting discounts and commissions and offering expenses. On July 1, 2021, we filed an omnibus shelf registration statement on Form S-3 with the Securities and Exchange Commission (SEC) that automatically became effective and allows us to undertake various equity and debt offerings. In addition, on January 27, 2022, the Company entered into a Sales Agreement with the Agents pursuant to which the Company may offer and sell from time to time through the Agents up to $150 million in shares of the Company’s common stock through an “at-the-market” program. As of February 24, 2022, we had not sold any shares of common stock under the Sales Agreement. Based on our

47

Table of Contents

current operating plan, we believe that our existing cash, cash equivalents, and investments will be sufficient to fund our projected operations at least 12 months after the date of issuance of the financial statements. Our estimate as to how long we expect our existing cash, cash equivalents, and investments to be available to fund our operations is based on assumptions that may prove inaccurate, and we could use our available capital resources sooner than we currently expect. In addition, changing circumstances may cause us to increase our spending significantly faster than we currently anticipate, and we may need to spend more money than currently expected because of circumstances beyond our control. We may need to raise additional funds sooner than we anticipate if we choose to expand more rapidly than we presently anticipate.

We will require additional capital for the further development and, if approved, commercialization of our product candidates. Our future funding requirements will depend on many factors, including but not limited to:

To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing, if available, may involve agreements that include the issuance of warrants or covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, or declaring dividends. If we raise funds through collaborations, strategic alliances, or licensing arrangements with pharmaceutical partners, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs, or product candidates, or grant licenses on terms that may not be favorable to us. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.

Additional capital may not be available when we need it, on terms acceptable to us or at all. We have no committed source of additional capital. If adequate capital is not available to us on a timely basis or on acceptable terms, we may be required to significantly delay, scale back, or discontinue our research and development programs or the commercialization of any product candidates, if approved, or be unable to continue or expand our operations, or otherwise capitalize on our business opportunities, as desired, which could materially affect our business, financial condition, results of operations, and growth prospects, and cause the price of our common stock to decline.

We may not be successful in our efforts to use and expand our proprietary technology platform to build a pipeline of oral biologic product candidates.

A key element of our strategy is to leverage our technology platform to expand our pipeline of oral biologic product candidates and in order to do so, we must continue to invest in our platform and development capabilities. Although our research and development efforts to date have resulted in a pipeline of product candidates, these product candidates may not be safe and effective. In addition, although we expect that our platform will allow us to develop a diverse pipeline of product candidates across multiple therapeutic areas and modalities, we may not prove to be successful at doing so. Furthermore, we may also find that the uses of our platform are limited because alternative uses of our biologic therapeutics prove not to be safe or effective. Even if we are successful in continuing to build our pipeline, the potential product candidates that we identify may not be suitable for clinical development, including as a result of being shown to have harmful side effects or other characteristics that indicate that they are unlikely to be products that will receive marketing approval or achieve market acceptance. Even after approval, if we cannot successfully develop or commercialize our products, or if serious adverse events are discovered after commercialization, we will not be able to generate any product revenue, which would adversely affect business.

We have limited resources and are currently focusing our efforts on developing AMT-101 and AMT-126 for particular indications and advancing our preclinical studies and clinical trials. As a result, we may fail to capitalize on other indications or product candidates that may ultimately have proven to be more profitable.

We are currently focused on developing our most advanced product candidates: AMT-101 and AMT-126. Our goal is to expand the therapeutic and commercial potential of our targets and product candidates to additional indications to maximize value and increase our probability of success. However, due to the significant resources required for the development of our product candidates, we must focus on specific product candidates and decide which product candidates to pursue and advance and the amount of resources to allocate to each. Our decisions concerning the allocation of research, development, collaboration, management, and financial resources toward particular product candidates or indications may not lead to the development of any viable commercial product and may divert resources away from better opportunities. If we make incorrect determinations regarding the viability or market potential of any of our product candidates or misread trends in immunology and inflammation, gastroenterology, and metabolic diseases, or the biopharmaceutical industry as a whole, our business, financial condition and results of operations could be materially adversely affected. As a result, we may fail to maximize profitability on our product candidates, capitalize on viable commercial products or profitable market opportunities, be required to forego or delay pursuit of opportunities with other product candidates or other indications that may later prove to have greater commercial potential than those we choose to pursue, or relinquish valuable rights to such product candidates through collaboration, licensing, or other royalty arrangements in cases in which it would have been advantageous for us to invest additional resources to retain sole development and commercialization rights.

We expect to rely on third parties to conduct our clinical trials and some aspects of our research and preclinical studies, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such trials, research, or testing.

We currently rely and expect to continue to rely on third parties, such as contract research organizations (CROs), contract development and manufacturing organizations (CDMOs), medical institutions, academic institutions, and clinical investigators to conduct some aspects of our research and preclinical studies and our clinical trials. Any of these third parties may terminate their engagements with us or be unable to fulfill their contractual obligations for any reason including the COVID-19 pandemic. For example, as a result of ongoing COVID-19 research and the current global supply chain issues, there is currently limited availability for certain resources required to conduct some of our preclinical studies and clinical trials, which has resulted in and may continue to result in longer lead times, increased costs, and delays in completing preclinical studies and clinical trials. If we need to enter into alternative arrangements or are unable to find suitable alternative arrangements, it would delay our product development activities.

Our reliance on third parties for research and development activities reduces our control over these activities but does not relieve us of our responsibilities. For example, we remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with current good clinical practices (cGCP) for conducting, recording, and reporting the results of clinical trials to assure that data and reported results are credible, reproducible, and accurate and that the rights,

49

Table of Contents

integrity, and confidentiality of trial participants are protected. We also are required to register ongoing clinical trials and post the results of completed clinical trials on a government-sponsored database within certain timeframes. Failure to do so can result in fines, adverse publicity, and civil and criminal sanctions.

If third parties do not successfully carry out their contractual duties, meet expected deadlines, or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we may be unable to complete, or may be delayed in completing, our preclinical studies or our clinical trials, and we will not be able to obtain, or may be delayed in obtaining, marketing approvals for any product candidates we may develop and will not be able to, or may be delayed in our efforts to, successfully commercialize our medicines. For example, we have increased total enrollment from 30 patients to between 40 and 50 patients due to an imbalance in the trial’s planned 1:1 randomization for the Phase 2 MARKET combination trial of oral AMT-101 with anti-TNFα in moderate-to-severe ulcerative colitis patients. The trial has been and continues to be blinded. In addition, currently there is a conflict involving Russia and Ukraine, and this has and may continue to impact our CROs, CDMOs and clinical investigators’ ability to conduct certain of our trials in Ukraine, Russia and other Eastern European countries, and may prevent us from obtaining data on patients already enrolled at sites in these countries. This could negatively impact the completion of our clinical trials and/or analyses of clinical results, which could materially harm our business.

We also expect to rely on other third parties to store and distribute supplies for our clinical trials. Any performance failure on the part of our distributors, including with the shipment of any supplies for our clinical trials, could delay clinical development or marketing approval of any product candidates we may develop or commercialization of our medicines, producing additional losses and depriving us of potential product revenue.

The manufacturing of our product candidates is complex. We and our third-party manufacturers may encounter difficulties in production. If we encounter any such difficulties, our ability to supply our product candidates for clinical trials or, if approved, for commercial sale, could be delayed or halted entirely.

Manufacturing of biologic therapeutics is a complex process and represents a critical path to creating oral biologic product candidates and a key component of our long-term success. We have spent significant resources and plan to continue to spend significant resources to develop our current manufacturing capabilities, processes and know-how to produce sufficient supply of our product candidates. While we previously qualified a manufacturing facility located in South San Francisco, we have now relocated the manufacturing equipment to a new facility in our new corporate headquarters in South San Francisco. Qualifying our new manufacturing facility is time intensive and costly and we may experience difficulties associated with the transition, including as a result of the COVID-19 pandemic. Although we have successfully manufactured certain preclinical and clinical supply at our previously qualified manufacturing facility, we will need to do so at our new location and may encounter difficulties.

We will continue to rely on third-party manufacturers to execute certain steps in the manufacturing of our product candidates. The facilities used by our contract manufactures to manufacture our product candidates are subject to various regulatory requirements and may be subject to the inspection of FDA or other regulatory authorities.  We do not control the manufacturing process of, and are dependent on, our contract manufacturing partners for compliance with the regulatory requirements, known as cGMPs.  If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or comparable regulatory authorities in foreign jurisdictions, we may not be able to rely on their manufacturing facilities for the manufacture of our product candidates.  In addition, we have limited control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance, and qualified personnel.  If the FDA or a comparable foreign regulatory authority finds these facilities inadequate for the manufacture of our product candidates or if such facilities are subject to enforcement action in the future or are otherwise inadequate, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates.

The process of manufacturing our product candidates is extremely susceptible to product loss due to contamination, equipment failure or improper installation or operation of equipment, vendor or operator error, inconsistency in yields, variability in product characteristics, and difficulties in scaling the production process. We have experienced in the past situations in which a contract manufacturer has failed to successfully complete a scheduled manufacturing run as a result of their manufacturing process errors or deviations from the product specifications. We also have experienced in the past situations in which we failed to successfully complete a schedule manufacturing run at our primary manufacturing site. Even minor deviations from normal manufacturing processes could result in reduced production

50

Table of Contents

yields, product defects and other supply disruptions. If microbial, viral, or other contaminants are discovered in our product candidates or in the manufacturing facilities in which our product candidates are made, we may have to quarantine impacted manufacturing lots pending an impact assessment, or such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination.

Any adverse developments affecting manufacturing operations for our product candidates, if any are approved, may result in shipment delays, inventory shortages, lot failures, product withdrawals or recalls, or other interruptions in the supply of our products. We may also have to take inventory write-offs and incur other charges and expenses for products that fail to meet specifications, undertake costly remediation efforts or seek more costly manufacturing alternatives. Furthermore, it is too early to estimate our cost of goods sold. The actual cost to manufacture our product candidates could be greater than we expect because we are early in our development efforts and our platform is based on a novel therapeutic approach. Failure to develop our own manufacturing capacity may hamper our ability to further process improvement, maintain quality control, limit our reliance on contract manufacturers, and protect our trade secrets and other intellectual property.

We currently rely on third-party manufacturers to produce our product candidates. Any failure by a third-party manufacturer to produce acceptable product candidates for us pursuant to our specifications and regulatory standards may delay or impair our ability to initiate or complete our clinical trials, obtain and maintain regulatory approvals or commercialize approved products.

We currently have limited internal manufacturing experience and personnel. While we are transitioning our internal manufacturing to our new facility, we expect that facility will be a site for the manufacture of product candidates, and we do not currently have the infrastructure or internal capability to manufacture our product candidates for commercialization purposes. We expect to continue to rely on third parties for certain manufacturing operations of our product candidates for preclinical studies and clinical trials, in compliance with applicable regulatory and quality standards, including cGMP, and may do so for the commercial manufacture of some or all of our product candidates, if approved. If we are unable to arrange for and maintain third-party manufacturing sources that are capable of meeting regulatory standards, or fail to do so on commercially reasonable terms, we may not be able to successfully produce sufficient supply of product candidate or we may be delayed in doing so. If we were to experience an unexpected loss of supply of our product candidates, for any reason, whether as a result of manufacturing, supply, logistics, or storage issues, the COVID-19 pandemic, or otherwise, we could experience delays, disruptions, suspensions, or terminations of, or be required to restart or repeat, any pending or ongoing clinical trials. Such failure or substantial delay or loss of supply could materially harm our business.

Reliance on third-party manufacturers entails risks including:

51

Table of Contents

In addition, the FDA, European Medicines Agency (EMA), and other regulatory authorities require that our product candidates be manufactured according to cGMP and similar foreign standards. Pharmaceutical manufacturers and their subcontractors are required to register their facilities or products manufactured at the time of submission of the marketing application and then annually thereafter with the FDA and certain state and foreign agencies. They are also subject to periodic unannounced inspections by the FDA, state, and other foreign authorities. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain marketing approval for or market our product candidates, if approved. Any subsequent discovery of problems with a product, or a manufacturing or laboratory facility used by us or our strategic partners, may result in sanctions being imposed on us, including fines, injunctions, civil penalties, restrictions on the product or on the manufacturing or laboratory facility, including license revocation, marketed product recall, suspension of manufacturing, product seizure, voluntary withdrawal of the product from the market, operating restrictions, or criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates and harm our business and results of operations.

We may have little to no control regarding the occurrence of third-party manufacturer incidents. Any failure by our third-party manufacturers to comply with cGMP or failure to scale up manufacturing processes, including any failure to deliver sufficient quantities of product candidates in a timely manner, would lead to a delay in, or failure to seek or obtain, regulatory approval of any of our product candidates. Furthermore, any change in manufacturer of our product candidates or approved products, if any, would require new regulatory approvals, which could delay completion of clinical trials or disrupt commercial supply of approved products.

Our current and anticipated future dependence upon others for the manufacture of our product candidates may adversely affect our future profit margins and our ability to commercialize any product candidates that receive marketing approval on a timely and competitive basis.

In some cases, the technical skills or technology required to manufacture our product candidates may be unique or proprietary to the original manufacturer, we may have difficulty transferring such skills or technology to another third-party and a feasible alternative may not exist. These factors would increase our reliance on such manufacturer or require us to obtain a license from such manufacturer in order to have another third-party manufacture our product candidates. If we are required to change manufacturers for any reason, we will be required to verify that the new manufacturer maintains facilities and procedures that comply with quality standards and with all applicable regulations and guidelines. The delays associated with the verification of a new manufacturer could negatively affect our ability to develop product candidates in a timely manner or within budget.

We depend on third-party suppliers for key raw materials used in our manufacturing processes, and the loss of these third-party suppliers or their inability to supply us with adequate raw materials could harm our business.

We rely on third-party suppliers for the raw materials required for the production of our product candidates. Our dependence on these third-party suppliers and the challenges we may face in obtaining adequate supplies of raw materials involve several risks, including delays as a result of COVID-19, the United Kingdom’s (UK) withdrawal from the European Union (Brexit) and recent global supply chain disruptions, limited control over pricing, availability, quality and delivery schedules. For example, as a result of Brexit, the movement of goods between the UK and the remaining member states of the EU are subject to additional inspections and documentation checks. As a result, we have experienced delays in our supply chain.

As a small company, our negotiation leverage is limited, and we are likely to get lower priority than our competitors who are larger than we are. We do not have long-term supply agreements, and we purchase our required supplies on a development manufacturing services agreement or purchase order basis. We cannot be certain that our suppliers will continue to provide us with the quantities of these raw materials that we require or satisfy our anticipated specifications and quality requirements. Any supply interruption in limited or sole sourced raw materials could materially harm our ability to manufacture our product candidates until a new source of supply, if any, could be identified and qualified. We may be unable to find a sufficient alternative supply in a reasonable time or on commercially reasonable terms. Any performance failure on the part of our suppliers could delay the development and potential commercialization of our product candidates, including limiting supplies necessary for clinical trials and regulatory approvals, which would have a material adverse effect on our business.

We will need to grow the size and capabilities of our organization, and we may experience difficulties in managing this growth.

As of December 31, 2021, we had 125 full-time employees. As our development plans and strategies develop, we must add a significant number of additional managerial, operational, financial, and other personnel. Future growth will impose significant added responsibilities on members of management, including:

Our future financial performance and our ability to continue to develop and, if approved, commercialize our product candidates will depend, in part, on our ability to effectively manage any future growth. Our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to manage these growth activities.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors, and consultants to provide certain services. There can be no assurance that the services of these independent organizations, advisors, and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed, or terminated, and we may not be able to obtain regulatory approval of our product candidates or otherwise advance our business. There can be no assurance that we will be able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, if at all.

If we are not able to effectively expand our organization by hiring new employees, retaining our existing employees, and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop our product candidates and, accordingly, may not achieve our research, development, and commercialization goals.

The COVID-19 pandemic, and actions taken to mitigate the spread of the virus, has impacted and could continue to adversely impact our business including our ongoing and planned clinical trials and preclinical studies.

Since the COVID-19 virus was reported in December 2019 in Wuhan, China, the virus has spread extensively throughout the world, resulting in the World Health Organization characterizing COVID-19 as a pandemic. While significant progress in addressing the pandemic has been made with multiple vaccines and treatment options now available, the emergence of highly transmissible variants of the virus, such as the Delta and Omicron variants, have resulted in periodic surges in infection rates around the world and a cycle of fluctuating public health restrictions designed to mitigate the spread of the virus. The extent to which the COVID-19 pandemic impacts our business will depend on future developments, which are highly uncertain and cannot be predicted, such as the spread or emergence of new variants, the duration and severity of surges in outbreaks, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions, and the effectiveness of actions taken in the United States and other countries to contain and treat the disease and to address its impact, including on financial markets or otherwise. As a result of the COVID-19 pandemic we have experienced and could experience future disruptions that could severely impact our business, current and planned clinical trials and preclinical studies, including:

Further, as a result of the COVID-19 pandemic, the extent and length of which is uncertain, we have and may continue to develop and implement additional clinical trial policies and procedures designed to help protect trial participants from the COVID-19 virus, which may include using telemedicine visits, remote monitoring of patients and clinical sites, and measures to ensure that data from clinical trials that may be disrupted as a result of the pandemic are collected pursuant to the trial protocol and consistent with cGCP, with any material protocol deviation reviewed and approved by the site Institutional Review Board (IRB). Patients who may miss scheduled appointments, any interruption in trial drug supply, or other consequence that may result in incomplete data being generated during a trial as a result of the pandemic must be adequately documented and justified. For example, the FDA issued guidance on March 18, 2020, which the FDA subsequently updated, on conducting clinical trials during the pandemic, which describe a number of considerations for sponsors of clinical trials impacted by the pandemic, including the requirement to include in the clinical trial report (or as a separate document) contingency measures implemented to manage the trial, and any disruption of the trial as a result of the COVID-19 pandemic; a list of all trial participants affected by the COVID-19-pandemic related trial disruption by unique subject identifier and by investigational site, and a description of how the

individual’s participation was altered; and analyses and corresponding discussions that address the impact of implemented contingency measures (e.g., participant discontinuation from investigational product and/or trial, alternative procedures used to collect critical safety and/or efficacy data) on the safety and efficacy results reported for the trial. We have implemented certain of these measures. In June 2020, the FDA also issued a guidance on good manufacturing practice considerations for responding to COVID-19 infection in employees in drug products manufacturing, including recommendations for manufacturing controls to prevent contamination of drugs. Additional COVID-19 related guidance released by FDA include guidance addressing resuming normal drug and biologics manufacturing operations; manufacturing, supply chain, and inspections; and statistical considerations for clinical trials during the COVID-19 public health emergency. In view of the spread of the COVID-19 variants, FDA may issue additional guidance and policies that may materially impact our business and clinical development timelines. Changes to existing policies and regulations can increase our compliance costs or delay our clinical plans.

While the extent of the impact of the COVID-19 pandemic and current and future regulatory policies and requirements on our business and financial results are uncertain, a continued and prolonged public health crisis such as the COVID-19 pandemic could have a material negative impact on our business, financial condition, and operating results.

To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of December 31, 2021 and December 31, 2020, we had federal and California net operating loss (NOL) carryforwards of approximately $252.1 million and $69.4 million, respectively. The federal NOL carryforwards arising in the tax year ending December 31, 2017 and earlier tax years will begin to expire in 2036, if not utilized. Realization of these NOLs depends on future income, and there is a risk that our existing NOLs could expire unused and be unavailable to offset future income tax liabilities, which could adversely affect our operating results.

Under Sections 382 and 383 of the United States Internal Revenue Code of 1986, as amended (the Code), if a corporation undergoes an “ownership change” (generally defined as a greater than 50-percentage-point cumulative change (by value) in the equity ownership of certain stockholders over a rolling three-year period), the corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes to offset its post-change taxable income or taxes may be limited. As a result of our private placements, our IPO in June 2020, and other transactions that have occurred since our incorporation, we may have experienced such an ownership change. We may also experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which are outside our control.

As a result, our ability to use our pre-change NOL carryforwards and other pre-change tax attributes to offset post-change taxable income or taxes may be subject to limitation.

Changes in our effective tax rate or tax liability may have an adverse effect on our operating results.

Our effective tax rate and the amount of our taxable income could be adversely affected by several factors, many of which are outside our control, including:

55

Table of Contents

For example, the current administration has proposed to increase the U.S. corporate income tax rate, increase U.S. taxation of international business operations, and impose a global minimum tax. Any of these developments or changes in federal, state, or international tax laws or tax rulings could adversely affect our effective tax rate and our operating results.

Risks Related to the Discovery, Development, and Commercialization of Our Product Candidates

Research and development related to novel biologic therapeutics is inherently risky. Our business is heavily dependent on the successful development of our product candidates, which are in preclinical and the early stages of clinical development. We cannot give any assurance that any of our product candidates will receive regulatory or marketing approval, which is necessary before they can be commercialized.

Our oral biologic product candidates’ use of active transport to translocate through the IE barrier is a novel therapeutic approach. Our active transport approach differs from current oral biologics and peptides and is unproven. We are at the early stages of development of our product candidates. Our future success is dependent on our ability to successfully develop, obtain regulatory approval for, and then successfully commercialize our product candidates, and we may fail to do so for many reasons, including the following:

If any of these events occur, we may be forced to abandon our development efforts for one or more product candidates, which would have a material adverse effect on our business and could potentially cause us to cease operations.

We may not be successful in our efforts to further develop our current product candidates. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any of our product candidates. Each of our product candidates are in the early stages of development and will require significant additional clinical development, management of preclinical, clinical, and manufacturing activities, regulatory approval, adequate manufacturing supply, a commercial organization, and significant marketing efforts before we generate any revenue from product sales, if at all.

We have never completed a clinical development program. We currently have two product candidates, AMT-101 and AMT-126. None of our product candidates have advanced into late-stage development and it may be years before any such trial is initiated, if at all. Further, we cannot be certain that any of our product candidates will be successful in clinical trials. We may in the future advance product candidates into clinical trials and terminate such trials prior to their completion.

56

Table of Contents

If any of our product candidates successfully complete clinical trials, we generally plan to seek regulatory approval to market our product candidates in the United States, the European Union, and in additional foreign countries where we believe there is a viable commercial opportunity. We have never commenced, compiled or applied for regulatory approval to market any product candidate. We may never receive regulatory approval to market any product candidates even if such product candidates successfully complete clinical trials, which would adversely affect our viability. To obtain regulatory approval in countries outside of the United States, we must comply with numerous and varying regulatory requirements of such other countries regarding safety, efficacy, manufacturing and controls, clinical trials, commercial sales, pricing, and distribution of our product candidates. Even if we are successful in obtaining approval in one jurisdiction, we cannot ensure that we will obtain approval in any other jurisdictions. If we are unable to obtain approval for our product candidates in multiple jurisdictions, our business, financial condition, results of operations, and our growth prospects could be negatively affected.

Even if we receive regulatory approval to market any of our product candidates, we cannot assure you that any such product candidate will be successfully commercialized, widely accepted in the marketplace or more effective than other commercially available alternatives.

Investment in biopharmaceutical product development involves significant risk that any product candidate will fail to demonstrate adequate efficacy or an acceptable safety profile, gain regulatory approval, and become commercially viable. We cannot provide any assurance that we will be able to successfully advance any of our product candidates through the development process or, if approved, successfully commercialize any of our product candidates.

We may encounter delays in our preclinical studies or clinical trials, or may not be able to conduct or complete our preclinical studies or clinical trials on the timelines we expect, if at all.

Preclinical studies and clinical testing are expensive, time consuming, and subject to uncertainty. We cannot guarantee that any preclinical studies and clinical trials will be conducted as planned or completed on schedule, if at all. We cannot be sure that submission of an IND application or a CTA will result in the FDA, EMA, or other regulatory authority, as applicable, allowing clinical trials to begin in a timely manner, if at all. Moreover, even if these studies or trials begin, issues may arise that could suspend or terminate such preclinical studies or clinical trials. A failure of one or more preclinical studies or clinical trials can occur at any stage of testing, and our future preclinical studies or clinical trials may not be successful. Events that may prevent successful or timely initiation or completion of preclinical studies or clinical trials include:

57

Table of Contents

Any inability to successfully initiate or complete preclinical studies or clinical trials could result in additional costs to us or impair our ability to generate revenue. In addition, if we make manufacturing or formulation changes to our product candidates, we may be required, or we may elect, to conduct additional studies to bridge our modified product candidates to earlier versions. Preclinical studies or clinical trial delays could also shorten any periods during which our products have patent protection and may allow our competitors to bring products to market before we do, which could impair our ability to successfully commercialize our product candidates and may harm our business and results of operations.

We have experienced in the past situations in which a contract manufacturer has failed to successfully complete a scheduled manufacturing run as a result of their manufacturing process errors or deviations from the product specifications. We also have experienced in the past situations in which we failed to successfully complete a schedule manufacturing run at our primary manufacturing site. These situations have the potential to cause delays in timelines and increases in development costs.

We could also encounter delays if a preclinical study or clinical trial is suspended or terminated by us, by the data safety monitoring board for such trial or by the FDA, EMA, or any other regulatory authority, or if the IRBs of the institutions in which such trials are being conducted suspend or terminate the participation of their clinical investigators and sites subject to their review. Such authorities may suspend or terminate a clinical trial due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA, EMA, or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions, or lack of adequate funding to continue the clinical trial.

We may in the future terminate our clinical trials prior to their completion, which could adversely affect our business.

58

Table of Contents

Delays in the completion of any preclinical study or clinical trial of our product candidates will increase our costs, slow down our product candidate development and approval process, and delay, or potentially jeopardize our ability to commence product sales and generate revenue. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates.

If we do not achieve our projected development goals in the timeframes we announce and expect, our stock price may decline.

From time to time, we estimate the timing of the anticipated accomplishment of various scientific, clinical, regulatory and other product development goals, which we sometimes refer to as milestones. These milestones may include the commencement or completion of scientific studies and clinical trials, the public release of clinical data, and the submission of regulatory filings. From time to time, we may publicly announce the expected timing of some of these milestones. All of these milestones are and will be based on numerous assumptions. The actual timing of these milestones can vary dramatically compared to our estimates, in some cases for reasons beyond our control. For example, we have previously updated our anticipated timelines for milestones for our clinical trials that were publicly announced. If we do not meet milestones as publicly announced, our stock price may decline.

We may encounter difficulties enrolling patients or healthy volunteers in our clinical trials, and our clinical development activities could thereby be delayed or otherwise adversely affected.

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. We have experienced and may experience difficulties in patient enrollment in our clinical trials for a variety of reasons, including:

We may also need to increase our planned enrollment for clinical trials. For example, we have increased total enrollment from 30 patients to between 40 and 50 patients due to an imbalance in the trial’s planned 1:1 randomization for the Phase 2 MARKET combination trial of oral AMT-101 with anti-TNFα in moderate-to-severe ulcerative colitis patients. The trial has been and continues to be blinded. In addition, the size and nature of the patient populations of the indications for which we are targeting may present difficulties or delays in enrollment due to factors such as being orphan disease populations or competition for patients with other trials. For example, we are aware of multiple clinical trials in UC being conducted by competitors, and certain of our ongoing trials are competing for the same patient population, both of which may make it difficult for us to enroll sufficient patients.

59

Table of Contents

Our preclinical studies and clinical trials may fail to demonstrate evidence of the safety and efficacy of our product candidates, which would prevent, delay, or limit the scope of regulatory approval and commercialization.

Before obtaining regulatory approvals for the commercial sale of any of our product candidates, we must demonstrate through lengthy, complex, and expensive preclinical studies and clinical trials that our product candidates are both safe and effective for use in each target indication. Each product candidate must demonstrate an adequate risk versus benefit profile in its intended patient population and for its intended use.

Preclinical studies and clinical testing are expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the preclinical studies or clinical trial process. The results of preclinical studies of our product candidates may not be predictive of the results of early-stage or later-stage clinical trials, and results of early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. The results of clinical trials in one set of patients or disease indications may not be predictive of those obtained in another. In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same product candidate due to numerous factors, including variability in the purity or potency of different batches of the same product candidate, changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the dosing regimen, and other aspects of the clinical trial protocols and the rate of dropout among clinical trial participants. Open-label extension studies may also extend the timing and cost of a clinical development program substantially. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy profile despite having progressed through preclinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unacceptable safety issues, notwithstanding promising results in earlier trials. Most product candidates that begin clinical trials are never approved by regulatory authorities for commercialization.

We have limited experience in designing clinical trials and may be unable to design and execute a clinical trial to support marketing approval. We cannot be certain that our current clinical trials or any other future clinical trials will be successful. Additionally, any safety concerns observed in any one of our clinical trials in our targeted indications could limit the prospects for regulatory approval of our product candidates in those and other indications, which could have a material adverse effect on our business, financial condition, and results of operations.

In addition, even if such clinical trials are successfully completed, we cannot guarantee that the FDA or foreign regulatory authorities will interpret the results as we do, and more trials could be required before we submit our product candidates for approval. To the extent that the results of the trials are not satisfactory to the FDA or foreign regulatory authorities to advance a product candidate to the next phase of clinical development or for support of a marketing application, we may be required to expend significant resources, which may not be available to us, to conduct additional trials in support of potential approval of our product candidates. Even if regulatory approval is secured for any of our product candidates, the terms of such approval may limit the scope and use of our product candidates, which may also limit its commercial potential.

We face significant competition and if our competitors develop and market technologies or products that are more effective, safer or less expensive than our product candidates, our commercial opportunities will be negatively impacted.

The development and commercialization of biologic therapeutics is highly competitive and subject to rapid and significant technological change. We are currently developing biologic therapeutics that will compete with other drugs and therapies that currently exist or are being developed in the segments of the pharmaceutical, biotechnology, and other related markets that develop treatments for autoimmune, inflammatory, metabolic, and other diseases. The pharmaceutical and biotechnology industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on intellectual property. Any product candidates that we successfully develop and commercialize will compete with current therapies and new therapies that may become available in the future.

60

Table of Contents

We have competitors both in the United States and internationally, including major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical companies, universities, academic institutions, government agencies, and other public and private research organizations that conduct research, seek patent protection, and establish collaborative arrangements for the research, development, manufacturing, and commercialization of therapies aimed at treating autoimmune, inflammatory, metabolic, and other diseases. Many of our competitors have significantly greater financial, manufacturing, marketing, technical and human resources and commercial expertise than we do. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining regulatory approvals, recruiting patients and in manufacturing biologic therapeutics. These companies also have significantly greater research and marketing capabilities than we do. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make our product candidates obsolete. As a result of all of these factors, our competitors may succeed in obtaining patent protection or FDA or other regulatory approval or discovering, developing and commercializing products in our field before we do.

In particular, with respect to our most advanced product candidates, AMT-101 and AMT-126, we compete against companies that produce injectable biologic therapeutics such as AbbVie Inc., Amgen Inc., Eli Lilly and Co., Janssen Pharmaceuticals, Inc., Merck Sharp & Dohme Corp., Roche Holding Ltd., and Takeda Pharmaceutical Company Ltd., as well as companies that produce oral products such as Abivax SA, Arena Pharmaceuticals, Inc., Bristol-Myers Squibb Co., Galapagos NV, Gilead Sciences, Inc., Gossamer Bio, Inc., Landos Biopharma, Inc., Morphic Holding, Inc., Pfizer Inc., Prometheus Biosciences, Inc., Protagonist Therapeutics, Inc., and Theravance Biopharma, Inc.

We are not aware of any other company or organization that has developed an FDA-approved oral biologic, other than peptides. However, we are aware of other companies developing oral biologic product candidates using their own technology platform.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than the products that we may develop. Our competitors also may obtain FDA or foreign regulatory approval for their products more rapidly than we may obtain approval for our product candidates, which could result in our competitors establishing a strong market position before we are able to enter the market.

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, and retaining third-party manufacturing resources, as well as in acquiring technologies complementary to, or necessary for, our product candidates. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient, or are less expensive than any products that we may develop. Our competitors also may obtain FDA, EMA, or other regulatory approval for their products more rapidly than we may obtain approval for ours and may obtain orphan drug exclusivity from the FDA for indications our product candidates are targeting, which could result in our competitors establishing a strong market position before we are able to enter the market. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Technological advances or products developed by our competitors may render our technologies or product candidates obsolete, less competitive or not economical.

In addition, we could face litigation or other proceedings with respect to the scope, ownership, validity, and/or enforceability of our patents relating to our competitors’ products and our competitors may allege that our products infringe, misappropriate, or otherwise violate their intellectual property. The availability of our competitors’ products could limit the demand, and the price we are able to charge, for any products that we may develop and commercialize.

Our product candidates may face competition sooner than anticipated.

Even if we are successful in achieving regulatory approval to commercialize a product candidate ahead of our competitors, our product candidates may face competition from biosimilar products or alternative therapies. In the United States, our product candidates are regulated by the FDA as biologic products and we intend to seek approval

61

Table of Contents

for these product candidates pursuant to the BLA pathway. The Biologics Price Competition and Innovation Act of 2009 (BPCIA) created an abbreviated pathway for the approval of biosimilar and interchangeable biologic products. The abbreviated regulatory pathway establishes legal authority for the FDA to review and approve biosimilar biologics, including the possible designation of a biosimilar as “interchangeable” based on its similarity to an existing brand product. Under the BPCIA, an application for a biosimilar product cannot be approved by the FDA until 12 years after the original branded product was approved under a BLA. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. While it is uncertain when such processes intended to implement BPCIA may be fully adopted by the FDA, any such processes could have a material adverse effect on the future commercial prospects for our product candidates.

We believe that any of our product candidates approved as a biologic product under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider our product candidates to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Moreover, the extent to which a biosimilar product, once approved, will be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biologic products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing. In addition, a competitor could decide to forego the biosimilar approval path and submit a full BLA after completing its own preclinical studies and clinical trials. In such cases, any exclusivity to which we may be eligible under the BPCIA would not prevent the competitor from marketing its product as soon as it is approved.

In Europe, the European Commission has granted marketing authorizations for several biosimilar products pursuant to a set of general and product class-specific guidelines for biosimilar approvals issued over the past few years. In Europe, a competitor may reference data supporting approval of an innovative biological product but will not be able to get it on the market until 10 years after the time of approval of the innovative product. This 10-year marketing exclusivity period will be extended to 11 years if, during the first eight of those 10 years, the marketing authorization holder obtains an approval for one or more new therapeutic indications that bring significant clinical benefits compared with existing therapies. In addition, companies may be developing biosimilar products in other countries that could compete with our products, if approved.

If competitors are able to obtain marketing approval for biosimilars referencing our product candidates, if approved, such products may become subject to competition from such biosimilars, with the attendant competitive pressure and potential adverse consequences. Such competitive products may be able to immediately compete with us in each indication for which our product candidates may have received approval.

Even if any product candidates we develop receive marketing approval, our product candidates may not achieve adequate market acceptance by physicians, patients, healthcare payors, and others in the medical community necessary for commercial success.

The commercial success of any of our product candidates will depend upon its degree of market acceptance by physicians, patients, third-party payors, and others in the medical community. Even if any product candidates we may develop receive marketing approval, they may nonetheless fail to gain sufficient market acceptance by physicians, patients, healthcare payors, and others in the medical community. The degree of market acceptance of any product candidates we may develop, if approved for commercial sale, will depend on a number of factors, including:

62

Table of Contents

If any product candidates we develop do not achieve an adequate level of acceptance, we may not generate or derive sufficient revenue from that product candidate and our financial results could be negatively impacted.

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to sell and market any product candidates we may develop, we may not be successful in commercializing those product candidates if and when they are approved.

We do not have a sales or marketing infrastructure and have no experience in the sale, marketing, or distribution of biologic therapeutics. To achieve commercial success for any approved product for which we retain sales and marketing responsibilities, we must either develop a sales and marketing organization or outsource these functions to third parties. In the future, we may choose to build a focused sales, marketing, and commercial support infrastructure to sell, or participate in sales activities for some of our product candidates if and when they are approved.

There are risks involved with both establishing our own commercial capabilities and entering into arrangements with third parties to perform these services. For example, recruiting and training a sales force or reimbursement specialists is expensive and time consuming and could delay any product launch. If the commercial launch of a product for which we recruit a sales force and establish marketing and other commercialization capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our commercialization personnel.

Factors that may inhibit our efforts to commercialize any approved product on our own include:

If we enter into arrangements with third parties to perform sales, marketing, commercial support, and distribution services, our product revenue or the profitability of product revenue may be lower than if we were to market and sell any products we may develop ourselves. In addition, we may not be successful in entering into arrangements with third parties to commercialize our product candidates or may be unable to do so on terms that are favorable to us. We

63

Table of Contents

may have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we do not establish commercialization capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidates, if approved.

If the market opportunities for any product that we develop are smaller than we believe they are, our revenue may be adversely affected and our business may suffer.

Our projections of both the number of people who have the diseases we may be targeting, as well as the subset of people with these health issues who have the potential to benefit from treatment with our technology platform and investigational medicines, and any product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations, or market research, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases and health issues. The potentially addressable patient population for our investigational medicines may be limited or may not be amenable to treatment with our technology platform or investigational medicines. Even if we obtain significant market share for our products, if approved, if the potential target populations are small, we may never achieve profitability without obtaining regulatory approval for additional indications.

Risks Related to Regulatory Approval and Other Legal Compliance Matters

We may be unable to obtain U.S. or foreign regulatory approval for our product candidates and, as a result, may be unable to commercialize our product candidates.

The time required to obtain approval by the FDA, EMA, and comparable foreign regulatory authorities is unpredictable, typically takes many years following the commencement of clinical trials, and depends upon numerous factors, including the type, complexity, and novelty of the product candidates involved. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions, which may cause delays in the approval or the decision not to approve an application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional preclinical, clinical, or other studies. We have not submitted for, or obtained regulatory approval for any product candidate, and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever obtain regulatory approval.

Applications for our product candidates could fail to receive regulatory approval in an initial or subsequent indication for many reasons, including but not limited to the following:

64

Table of Contents

This lengthy approval process, as well as the unpredictability of the results of clinical trials, may result in our failing to obtain regulatory approval to market any of our product candidates, which would significantly harm our business, results of operations, and prospects.

The FDA, EMA and comparable foreign regulatory authorities have limited experience with our technology platform and we are not aware of any similar technology platform which has been approved by the FDA, EMA or comparable foreign regulatory authorities, which may increase the complexity, uncertainty and length of the regulatory approval process for our product candidates. For example, since the scientific evidence to support the feasibility of developing our product candidates and discovery programs is both preliminary and limited, the FDA may require us to provide additional data to support our regulatory applications. Moreover, advancing our novel oral biologic product candidates creates other significant challenges for us, including educating medical personnel regarding a novel technology platform and its potential efficacy and safety benefits.

Further, the ability of the FDA or other regulatory agencies to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, government shutdowns including as a result of the COVID-19 pandemic, and statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In response to the COVID-19 public health emergency, the FDA postponed most inspections of foreign manufacturing facilities and routine surveillance inspections of domestic manufacturing facilities in 2020. In May 2021, the FDA issued an updated guidance on manufacturing, supply chain, and drug and biological product inspections, indicating that it intends to continue using other tools and approaches where possible for pre-approval inspections, and that it will continue to conduct “mission-critical” inspections on a case-by-case basis, or, where possible to do so safely, resume prioritized domestic inspections, such as pre-approval and surveillance inspections. FDA resumed standard operations for domestic surveillance inspections in July 2021 but on December 29, 2021, FDA announced that due to the spread of the Omicron variant, it would revert back to conducting only mission critical foreign and domestic onsite inspections and would temporarily postpone certain other inspectional activities. The pause on domestic inspections was originally set to expire on January 19, 2022, but FDA extended the pause at least through Feb. 4 with the goal of restarting these activities “as soon as safely possible.” The agency announced that it would proceed with previously planned foreign surveillance inspections that have received country clearance and are within the CDC’s Level 1 or Level 2 COVID-19 travel recommendation; otherwise, the inspection would be rescheduled. FDA’s current goal is to return to a regular cadence for foreign surveillance inspections in April 2022. These actions in response to the Omicron variant are likely to affect some FDA approval decisions and the agency’s attempt to clear its inspections backlog. Furthermore, there is a risk that new COVID-19 variants could emerge that could continue to impact the operations of FDA, EMA, or comparable foreign regulatory authorities, which could negatively impact our regulatory development programs including the timing to complete ongoing clinical trials or our ability to start new clinical trials.  

In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. If a prolonged government shutdown occurs, or if global health or other concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities in a timely manner, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

We may never receive approval to market and commercialize any product candidate. Even if we obtain regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. We may be subject to post-marketing testing requirements to maintain regulatory approval. In addition, upon obtaining any marketing approvals, we may have difficulty in establishing the necessary sales and marketing capabilities to gain market acceptance.

If any of our product candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, and it may prove to be difficult or impossible to finance the further development of our pipeline. Any of these events would have a material and adverse effect on our business, financial condition, results of operations, and prospects.

Our product candidates may cause undesirable side effects or have other properties that could halt their clinical development, prevent their regulatory approval, limit their commercial potential, or result in significant negative consequences.

Adverse events or other undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay, or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, EMA, or other comparable foreign regulatory authorities. AMT-101 is a GI-selective oral fusion of IL-10, and previous clinical trials conducted in the field with systemic IL-10 showed significant toxicities that prevented further development. AMT-126 is a GI-selective oral fusion of IL-22, and in current trials conducted in the field with systemic IL-22, toxicities and adverse events have been observed.

Side effects could affect patient recruitment, the ability of enrolled patients to complete the trial, and/or result in potential product liability claims. We are required to maintain product liability insurance pursuant to certain of our development and commercialization agreements. We may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. A successful product liability claim or series of claims brought against us could adversely affect our results of operations, business, and reputation. In addition, regardless of merit or eventual outcome, product liability claims may result in impairment of our business reputation, withdrawal of clinical trial participants, costs due to related litigation, distraction of management’s attention from our primary business, initiation of investigations by regulators, substantial monetary awards to patients or other claimants, the inability to commercialize our product candidates, and decreased demand for our product candidates, if approved for commercial sale.

Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects or adverse events caused by such products, a number of potentially significant negative consequences could result, including but not limited to:

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could significantly harm our business, financial condition, results of operations, and growth prospects.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our products.

We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an even greater risk when and if we commercialize any products. For example, we may be sued if our products cause or are perceived to cause injury or are found to be otherwise unsuitable during clinical testing, manufacturing, marketing, or sale post-approval. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability, or a breach of warranties. Claims could also be asserted under state consumer protection laws. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit testing and commercialization of our products. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of products we develop. Our insurance policies may have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions.

If we succeed in developing any products, we intend to market them in the United States as well as the European Union and other foreign jurisdictions. In order to market and sell our products in other jurisdictions, we must obtain separate marketing approvals and comply with numerous and varying regulatory requirements.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, but a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA or EMA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing, and promotion of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

Table of Contents

Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties, and costs for us and could delay or prevent the introduction of our products in certain countries. If we or any partner we work with fail to comply with the regulatory requirements in international markets or fail to receive applicable marketing approvals, our target market will be reduced, and our ability to realize the full market potential of our product candidates will be harmed.

Coverage and reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance. If reimbursement is not available or is not sufficient for our products, it is less likely that our products will be widely used.

Even if our product candidates are approved for sale by the appropriate regulatory authorities, market acceptance and sales of these products will depend on coverage and reimbursement policies and may be affected by future healthcare reform measures. Third-party payors, such as government healthcare programs, private health insurers and health maintenance organizations, decide what therapies they will cover and establish the level of reimbursement for such therapies. We cannot be certain that coverage and reimbursement will be available or adequate for any products that we develop. If coverage and adequate reimbursement is not available or is available on a limited basis, we may not be able to successfully commercialize any of our product candidates, if approved.

There may be significant delays in obtaining coverage and reimbursement for newly approved therapies, and coverage may be more limited than the purposes for which the therapy is approved by the FDA, EMA or other regulatory authorities. Moreover, eligibility for coverage and reimbursement does not imply that a therapy will be paid for in all cases or at a rate that is commensurate with our product pricing that covers our costs, including research, development, manufacturing, sale and distribution expenses. Interim reimbursement levels for new therapies, if applicable, may also be insufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the therapy and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost therapies and may be incorporated into existing payments for other services. Further, no uniform policy for coverage and reimbursement exists in the United States, and coverage and reimbursement can differ significantly from payor to payor. Net prices for therapies may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future change to laws that presently restrict imports of therapies from countries where they may be sold at lower prices than in the United States. Our inability to promptly obtain coverage and adequate reimbursement from third-party payors, including both government-funded and private payors, for any approved products that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

We have conducted, and continue to conduct, clinical trials for AMT-101 and AMT-126 outside of the United States, and we may do so for our other product candidates, which exposes us to additional risks. For example, the FDA, EMA, and applicable foreign regulatory authorities may not accept data from such trials, in which case our development plans will be delayed, which could materially harm our business.

We conduct our Phase 2 clinical trials for AMT-101 and our Phase 1 clinical trial for AMT-126 in countries outside of the United States, and we plan to conduct additional future clinical trials outside the United States. The acceptance of trial data from clinical trials conducted outside the United States by the FDA, EMA, or applicable foreign regulatory authority may be subject to certain conditions. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the United States population and United States medical practice; and (ii) the trials were performed by clinical investigators of recognized competence and pursuant to cGCP regulations. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering, must be met. Many foreign regulatory bodies have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA, EMA, or any applicable foreign regulatory authority will accept data from trials conducted outside their applicable jurisdiction. If the FDA, EMA, or any applicable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of our business plan, and which may result in our product candidates not receiving approval or clearance for commercialization in the applicable jurisdiction.

Conducting trials outside the United States also exposes us to additional risks, including risks associated with:

68

Table of Contents

For example, currently there is a conflict involving Russia and Ukraine. Our AMT-101 Phase 2 FILLMORE, LOMBARD and MARKET trials currently include clinical trial sites located in Ukraine, Russia, and other Eastern European countries. This has and may continue to impact our ability to conduct certain of our trials in Ukraine, Russia and other Eastern European countries, and may prevent us from obtaining data on patients already enrolled at sites in these countries. This could negatively impact the completion of our clinical trials and/or analyses of clinical results, which could materially harm our business.

Also, recent and potential global supply chain disruptions and geo-political events may impact our ability to manufacture and deliver AMT-101 and AMT-126 to our clinical trial sites, particularly those outside the United States. If we or our contractors are unable to deliver sufficient quantities of a study product candidate, the completion of our clinical trials may be delayed, which could materially harm our business.

Further, Brexit and uncertainty in the regulatory framework as well as future legislation in the UK, European Union, and other jurisdictions can lead to disruption in the execution of international multi-center clinical trials, the monitoring of adverse events through pharmacovigilance programs, the evaluation of the benefit-risk profiles of new medicinal products, and determination of marketing authorization across different jurisdictions. Uncertainty in the regulatory framework could also result in disruption to the supply and distribution as well as the import/export of active pharmaceutical ingredients and finished product candidates. Such a disruption could create supply difficulties for ongoing clinical trials. The cumulative effects of the disruption to the regulatory framework, uncertainty in future regulation, and changes to existing regulations may increase our development lead time to marketing authorization and commercialization of products in the European Union and/or the UK and increase our costs. We cannot predict the impact of such changes and future regulation on our business or the results of our operations.

Preliminary data from our clinical trials that we announce or publish from time to time may change as additional patient data become available and are subject to verification procedures that could result in material changes in the final data or clinical conclusions.

From time to time, we may publicly disclose preliminary data from our clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial such as data from our clinical trials of AMT-101 and AMT-126. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published.  

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular product candidate, our ability to advance a product candidate to the next phase of clinical development, the approvability or commercialization of the particular product candidate or product, and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular drug, product candidate or our business.  If the preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for,

and commercialize, our product candidates including AMT-101 and AMT-126 may be harmed, which could harm our business, operating results, prospects or financial condition.

Even if we obtain regulatory approval for a product candidate, our products will remain subject to extensive regulatory scrutiny.

If any of our product candidates are approved, they will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping, conduct of post-marketing studies, and submission of safety, efficacy, and other post-market information, including both federal and state requirements in the United States and requirements of comparable foreign regulatory authorities.

Manufacturers and manufacturers’ facilities are required to comply with extensive requirements imposed by the FDA, EMA, and comparable foreign regulatory authorities, including ensuring that quality control and manufacturing procedures conform to cGMP regulations. As such, we and our contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any NDA, BLA, or marketing authorization application (MAA). Accordingly, we and others with whom we work must continue to expend time, money, and effort in all areas of regulatory compliance, including manufacturing, production, and quality control.

Any regulatory approvals that we receive for our product candidates will be subject to limitations on the approved indicated uses for which the product may be marketed and promoted or to the conditions of approval (including the requirement to implement a risk evaluation and mitigation strategy), or contain requirements for potentially costly post-marketing testing. We will be required to report certain adverse reactions and production problems, if any, to the FDA, EMA, and comparable foreign regulatory authorities. The FDA and other agencies, including the Department of Justice, closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are manufactured, marketed, and distributed only for the approved indications and in accordance with the provisions of the approved labeling. We will have to comply with requirements concerning advertising and promotion for our products. Promotional communications with respect to biologic therapeutics are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved label. As such, we may not promote our products for indications or uses for which they do not have approval, commonly referred to as “off-label uses.” The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label may be subject to significant liability. However, physicians may, in their independent medical judgment, prescribe legally available products for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments, but the FDA does restrict manufacturer communications on the subject of off-label use of their products. The holder of an approved NDA, BLA, or MAA must submit new or supplemental applications and obtain approval for certain changes to the approved product, product labeling, or manufacturing process. We could also be asked to conduct post-marketing clinical trials to verify the safety and efficacy of our products in general or in specific patient subsets. If original marketing approval was obtained via the accelerated approval pathway, we could be required to conduct a successful post-marketing clinical trial to confirm clinical benefit for our products. An unsuccessful post-marketing trial or failure to complete such a trial could result in the withdrawal of marketing approval.

If a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, or disagrees with the promotion, marketing or labeling of a product, such regulatory agency may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If we fail to comply with applicable regulatory requirements, a regulatory agency or enforcement authority may, among other things:

70

Table of Contents

Any government investigation of alleged violations of law could require us to expend significant time and resources in response, and could generate negative publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and generate revenue from our products. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our company and our operating results will be adversely affected.

We may seek orphan drug designation for one or more of our product candidates, but we may be unable to obtain such designations or to maintain the benefits associated with orphan drug status, including market exclusivity, which may cause our revenue, if any, to be reduced.

In the future, we may seek orphan drug designations for one or more of our product candidates, but may be unable to obtain an orphan drug designation for any additional product candidates. Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, defined as a disease or condition with a patient population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States when there is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United States for that drug or biologic. Orphan drug designation must be requested before submitting an NDA or BLA. In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other NDA or BLA applications to market the same drug or biologic for the same indication for seven years, except in limited circumstances such as a showing of clinical superiority to the product with orphan exclusivity or if FDA finds that the holder of the orphan exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan product to meet the needs of patients with the disease or condition for which the drug was designated. Furthermore, the FDA can waive orphan exclusivity if we are unable to manufacture sufficient supply of our product.

A breakthrough therapy designation or Fast Track designation by the FDA for a drug may not lead to a faster development or regulatory review or approval process, and it would not increase the likelihood that the drug will receive marketing approval.

In the future, we may seek a breakthrough therapy designation for one or more of our investigational medicines. A breakthrough therapy is defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For drugs that have been designated as breakthrough therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Drugs designated as breakthrough therapies by the FDA are also eligible for priority review if supported by clinical data at the time of the submission of the biologics license application.

71

Table of Contents

Designation as a breakthrough therapy is at the discretion of the FDA. Accordingly, even if we believe that one of our investigational medicines meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead determine not to make such designation. In any event, the receipt of a breakthrough therapy designation for a drug may not result in a faster development process, review, or approval compared to drugs considered for approval under conventional FDA procedures and it would not assure ultimate approval by the FDA. In addition, even if one or more of our investigational medicines qualify as breakthrough therapies, the FDA may later decide that the investigational medicine no longer meets the conditions for qualification, or it may decide that the time period for FDA review or approval will not be shortened.

We may seek Fast Track designation for some of our investigational medicines. If a therapy is intended for the treatment of a serious or life-threatening condition and the therapy demonstrates the potential to address significant unmet medical needs for this condition, the drug sponsor may apply for Fast Track designation. The FDA has broad discretion whether or not to grant this designation, and even if we believe a particular investigational medicine is eligible for this designation, we cannot assure you that the FDA would decide to grant it. Even if we do receive Fast Track designation, we may not experience a faster development process, review, or approval compared to conventional FDA procedures. If our clinical development program does not continue to meet the criteria for Fast Track designation, or if our clinical trials are delayed, suspended, or terminated, or put on clinical hold due to unexpected adverse events or issues with clinical supply, we will not receive the benefits associated with the Fast Track program. Furthermore, Fast Track designation and priority review do not change the standards for approval. The FDA may withdraw Fast Track designation if it believes that the designation is no longer supported by data from our clinical development program. Fast Track designation alone does not guarantee qualification for the FDA’s priority review procedures.

Current and future legislation may increase the difficulty and cost for us to commercialize our product candidates, if approved, and affect the prices we may obtain.

Third-party payors, whether domestic or foreign, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In both the United States and certain foreign jurisdictions, there have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal, and state levels directed at containing or lowering the cost of healthcare. We cannot predict the initiatives that may be adopted in the future. The continuing efforts of the government, insurance companies, managed care organizations, and other payors of healthcare services to contain or reduce costs of healthcare and/or impose price controls may adversely affect:

In March 2010, the Patient Protection and Affordable Care Act (ACA) was enacted, which includes measures that have significantly changed the way healthcare is financed by both governmental and private insurers. The ACA continues to significantly impact the United States’ pharmaceutical industry. Since its enactment, there have been executive, judicial and Congressional challenges to certain aspects of the ACA. In June 2021, the United States Supreme Court. held that Texas and other challengers had no legal standing to challenge the ACA, dismissing the case without specifically ruling on the constitutionality of the ACA. Accordingly, the ACA remains in effect in its current form. On January 28, 2021, President Biden issued an executive order instructing certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including, among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how this Supreme Court decision, future litigation, and healthcare measures promulgated by the current administration will impact the ACA, our business, financial condition and results of operations. Complying with any new legislation or reversing changes implemented under the ACA could be time-intensive and expensive, resulting in a material adverse effect on our business.

72

Table of Contents

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013 and will remain in effect through 2031 with the exception of a temporary suspension implemented under various COVID-19 relief legislation from May 1, 2020 through March 31, 2022, unless additional Congressional action is taken.

Moreover, there has recently been heightened governmental scrutiny over the manner in which drug manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. In 2020, under the Trump administration, HHS and CMS issued final rules in November and December of 2020 that were expected to impact, among others, price reductions from pharmaceutical manufacturers to plan sponsors under Part D, fee arrangements between pharmacy benefit managers and manufacturers, manufacturer price reporting requirements under the Medicaid Drug Rebate Program, including regulations that affect manufacturer-sponsored patient assistance programs subject to pharmacy benefit manager accumulator programs and Best Price reporting related to certain value-based purchasing arrangements. Multiple lawsuits have been brought against the HHS challenging various aspects of the rules.

Under the American Rescue Plan Act of 2021, effective January 1, 2024, the statutory cap on Medicaid Drug Rebate Program rebates that manufacturers pay to state Medicaid programs will be eliminated. Elimination of this cap may require pharmaceutical manufacturers to pay more in rebates than they receive on the sale of products, which could have a material impact on our business. In July 2021, the current administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at increasing competition for prescription drugs. In response to this executive order, the HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and potential legislative policies that Congress could pursue to advance these principles. In addition, Congress is considering legislation that, if passed, could have significant impact on prices of prescription drugs covered by Medicare, including limitations on drug price increases. The impact of these legislative, executive, and administrative actions and any future healthcare measures and agency rules implemented by the current administration on us and the biopharmaceutical industry as a whole is unclear. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our product candidates if approved.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. A number of states are considering or have recently enacted state drug price transparency and reporting laws that could substantially increase our compliance burdens and expose us to greater liability under such state laws once we begin commercialization if we obtain regulatory approval for any of our products. We are unable to predict the future course of federal or state healthcare legislation in the United States directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. These and any further changes in the law or regulatory framework that reduce our revenue or increase our costs could also have a material and adverse effect on our business, financial condition and results of operations.

We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, lower reimbursement, and new payment methodologies. This could lower the price that we receive for any approved product. Any denial in coverage or reduction in reimbursement from Medicare or other government-funded programs may result in a similar denial or reduction in payments from private payors, which may prevent us from being able to generate sufficient revenue, attain profitability, or commercialize our product candidates, if approved.

In the European Union, similar political, economic and regulatory developments may affect our ability to profitably commercialize our current or any future products. In addition to continuing pressure on prices and cost containment measures, legislative developments at the European Union or member state level may result in significant additional requirements or obstacles that may increase our operating costs. In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific

73

Table of Contents

products and therapies. Our future products, if any, might not be considered medically reasonable and necessary for a specific indication or cost-effective by third-party payors, an adequate level of reimbursement might not be available for such products and third-party payors’ reimbursement policies might adversely affect our ability to sell any future products profitably.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for biologic therapeutics. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-approval testing and other requirements.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, our product candidates may lose any marketing approval that may have been obtained and we may not achieve or sustain profitability, which would adversely affect our business. Further, it is possible that additional governmental action is taken in response to the COVID-19 pandemic.

Our employees, independent contractors, consultants, commercial partners, and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk of fraud, misconduct, or other illegal activity by our employees, independent contractors, consultants, commercial partners, and vendors. Misconduct by these parties could include intentional, reckless, and negligent conduct that fails to:

74

Table of Contents

If we obtain FDA approval of any of our product candidates and begin commercializing those products in the United States, our potential exposure under such laws will increase significantly, and our costs associated with compliance with such laws are also likely to increase. In particular, research, sales, marketing, education, and other business arrangements in the healthcare industry are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing, and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, educating, marketing and promotion, sales and commission, certain customer incentive programs, and other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. We have adopted a code of business conduct and ethics, but it is not always possible to identify and deter misconduct by employees and third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

If we fail to comply with healthcare laws, we could face substantial penalties and our business, operations, and financial conditions could be adversely affected.

If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our operations will be subject to various federal and state fraud and abuse laws. The laws that we are currently subject to or which we may become subject to if we obtain FDA approval of any of our product candidates, and which may impact our operations include the following:

75

Table of Contents

In addition, we are subject to federal and state consumer protection and unfair competition laws that broadly regulate marketplace activities and activities that potentially harm consumers.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could, despite our efforts to comply, be subject to challenge under one or more of such laws. Efforts to ensure that our business arrangements will comply with applicable healthcare laws may involve substantial costs. It is possible that governmental and enforcement authorities will conclude that our business practices may not comply with current or future statutes, regulations, or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant civil, criminal, and administrative penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid, and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations. In addition, the approval and commercialization of any of our product candidates outside the United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws.

If we or any contract manufacturers and suppliers we engage fail to comply with environmental, health, and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on our business.

We and any contract manufacturers and suppliers we engage are subject to numerous federal, state, and local environmental, health, and safety laws, regulations, and permitting requirements, including those governing laboratory procedures; the generation, handling, use, storage, treatment, and disposal of hazardous and regulated materials and wastes; the emission and discharge of hazardous materials into the ground, air, and water; and employee health and safety. Our operations involve the use of hazardous and flammable materials, including chemicals and biological and radioactive materials. Our operations also produce hazardous waste. We generally contract with third parties for the

76

Table of Contents

disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. Under certain environmental laws, we could be held responsible for costs relating to any contamination at our current or past facilities and at third-party facilities. We also could incur significant costs associated with civil or criminal fines and penalties.

Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair our research, product development, and manufacturing efforts. In addition, we cannot entirely eliminate the risk of accidental injury or contamination from these materials or wastes. Although we maintain workers’ compensation insurance to cover us for costs we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not carry specific biological or hazardous waste insurance coverage, and our property, casualty, and general liability insurance policies only provide limited coverage. Accordingly, in the event of contamination or injury, we could be held liable for damages or be penalized with fines in an amount exceeding our resources, and our clinical trials or regulatory approvals could be suspended, which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Our business activities may be subject to the Foreign Corrupt Practices Act (FCPA) and similar anti-bribery and anti-corruption laws, as well as U.S. and certain foreign export controls, trade sanctions, and import laws and regulations. We can face criminal liability and other serious consequences for violations, which can harm our business.

Our business activities may be subject to the FCPA and similar anti-bribery or anti-corruption laws, regulations or rules of other countries in which we operate. These laws generally prohibit companies and their employees and third party business partners, representatives and agents from engaging in corruption and bribery, including offering, promising, giving, or authorizing the provision of anything of value, either directly or indirectly, to a government official or commercial party in order to influence official action, direct business to any person, gain any improper advantage, or obtain or retain business. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect the transactions of the corporation and to devise and maintain an adequate system of internal accounting controls. Our business is heavily regulated and therefore involves significant interaction with government officials, including officials of non-U.S. governments. Additionally, in many countries, healthcare providers are employed by the government, and the purchasers of biopharmaceuticals are government entities; therefore, our dealings with these providers and purchasers are subject to regulation and such healthcare providers and employees of such purchasers may be considered “foreign officials” as defined in the FCPA. Recently, the SEC and Department of Justice have increased their FCPA enforcement activities with respect to biotechnology companies. In addition to our own employees, we leverage third parties to conduct our business abroad, such as managing our clinical trials and obtaining government licenses and approvals. We and our third-party business partners, representatives and agents may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities and we may be held liable for the corrupt or other illegal activities of our employees, our third-party business partners, representatives and agents, even if we do not explicitly authorize such activities. There is no certainty that our employees or the employees of our third-party business partners, representatives and agents will comply with all applicable laws and regulations, particularly given the high level of complexity of these laws. Violations of these laws and regulations could result in whistleblower complaints, adverse media coverage, investigations, loss of export privileges, debarment from U.S. and other government contracts, substantial diversion of management’s attention, significant legal fees and fines, severe criminal or civil sanctions against us, our officers, or our employees, disgorgement, and other sanctions and remedial measures, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our products in one or more countries and could materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, and our business, prospects, operating results, financial condition and stock price.

In addition, our products may be subject to U.S. and foreign export controls, trade sanctions and import laws and regulations. Governmental regulation of the import or export of our products, or our failure to obtain any required import or export authorization for our products, when applicable, could harm our business. Furthermore, U.S. export control laws and economic sanctions prohibit the provision of certain products and services to countries, governments, and persons targeted by U.S. sanctions. U.S. sanctions that have been or may be imposed as a result of the conflict between Russia and Ukraine may impact our ability to continue activities at clinical trial sites within regions covered by such sanctions. If we fail to comply with export and import regulations and such economic sanctions, penalties could be imposed, including fines and/or denial of certain export privileges.

Data collection under European and U.S. laws is governed by restrictive regulations addressing the collection, use, processing and, in the case of Europe, cross-border transfer, of personal information.

We may collect, process, use or transfer personal information from individuals located in the European Union in connection with our business, including in connection with conducting clinical trials in the European Union. Additionally, if any of our product candidates are approved, we may seek to commercialize those products in the European Union. The collection and use of personal health data in the European Union are governed by laws, regulations, and directives, including the General Data Protection Regulation (EU) 2016/679 (GDPR). This legislation imposes requirements relating to having legal bases for processing personal information relating to identifiable individuals and transferring such information outside of the European Economic Area, including to the United States, providing details to those individuals regarding the processing of their personal information, keeping personal information secure, having data processing agreements with third parties who process personal information, responding to individuals’ requests to exercise their rights in respect of their personal information, reporting security breaches involving personal data to the competent national data protection authority and affected individuals, appointing data protection officers, conducting data protection impact assessments and record-keeping. This legislation imposes significant responsibilities and liabilities in relation to personal data that we process, and we may be required to put in place additional mechanisms ensuring compliance. In particular, with respect to cross-border transfers of personal data, judicial and regulatory developments in the European Union have created uncertainty. In a decision issued by the Court of Justice of the European Union (CJEU) on July 16, 2020, the CJEU invalidated one mechanism for cross-border personal data transfer, the EU-U.S. Privacy Shield, and imposed additional obligations on companies, including us, relying on standard contractual clauses (SCCs) issued by the European Commission for cross-border personal data transfers. The European Commission released new SCCs designed to address the CJEU concerns on June 4, 2021. We have undertaken certain efforts to conform transfers of personal data from the European Economic Area (EEA) to the United States to our understanding of current regulatory obligations and guidance of data protection authorities, but the CJEU’s decision, the revised SCCs, regulatory guidance and opinions, and other developments relating to cross-border data transfer may require us to implement additional contractual and technical safeguards for any personal data transferred out of the EEA, which may increase compliance costs, lead to increased regulatory scrutiny or liability, may require additional contractual negotiations, and may adversely impact our business, financial condition and operating results. Any actual or alleged failure to comply with the requirements of the GDPR or other laws, regulations, and directives of the member states of the European Union may result in substantial fines, other administrative penalties and civil claims being brought against us, which could have a material adverse effect on our business, financial condition and results of operations.

In addition, U.S. states are adopting new laws or amending existing laws and regulations, requiring attention to frequently changing regulatory requirements applicable to data related to individuals. For example, California has enacted the California Consumer Privacy Act (CCPA), which took effect on January 1, 2020 and has been dubbed the first “GDPR-like” law in the United States. The CCPA gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used by requiring covered companies to provide new disclosures to California consumers (as that term is broadly defined and which can include any of our current or future employees who may be California residents or any other California residents whose data we collect or process) and provide such residents new ways to opt out of certain sales of personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. As we expand our operations and trials (both preclinical or clinical), the CCPA may increase our compliance costs and potential liability. Some observers have noted that the CCPA could mark the beginning of a trend toward more stringent privacy legislation in the United States.

Additionally, a new privacy law, the California Privacy Rights Act (CPRA), was approved by California voters in the election on November 3, 2020. The CPRA creates obligations relating to consumer data beginning on January 1, 2022, with implementing regulations expected on or before July 1, 2022, and enforcement beginning July 1, 2023. The CPRA modifies the CCPA significantly, potentially resulting in further uncertainty and requiring us to incur additional costs and expenses in an effort to comply. Additionally, other U.S. states continue to propose, and in certain cases adopt, privacy-focused legislation such as Colorado and Virginia. Aspects of these state laws remain unclear, resulting in further uncertainty and potentially requiring us to modify our data practices and policies and to incur substantial additional costs and expenses in an effort to comply.

Laws, regulations, and directives relating to privacy and data security are not consistent across jurisdictions, and they may impose conflicting or uncertain obligations. Compliance with laws, regulations, and directives is a rigorous, costly, and time-intensive process, and we may find it necessary or appropriate to put in place additional mechanisms ensuring compliance with new and changing data protection obligations. Actual or alleged noncompliance with any such laws, regulations, and directives may lead to regulatory investigations, enforcement actions and other proceedings, claims, and litigation, with the potential for significant fines, penalties, and other liabilities in the event of actual or alleged noncompliance. Any of these could adversely affect our business, financial condition and results of operations.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain patent protection for any product candidates we develop, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize any product candidates we may develop may be adversely affected.

Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries with respect to our proprietary product candidates and other technologies we may develop. We seek to protect our proprietary position by filing patent applications in the United States and abroad relating to our core programs and product candidates, as well as other technologies that are important to our business. We have filed or intend to file patent applications on aspects of our technology and core product candidates; however, there can be no assurance that any such patent applications will issue as granted patents around the world. The requirements for patentability differ in certain countries, and certain countries have heightened requirements for patentability. Furthermore, in some cases, we have only filed provisional patent applications on certain aspects of our technology and product candidates and each of these provisional patent applications is not eligible to become an issued patent until, among other things, we file a non-provisional patent application within 12 months of the filing date of the applicable provisional patent application. Any failure to file a non-provisional patent application within this timeline could cause us to lose the ability to obtain patent protection for the inventions disclosed in the associated provisional patent applications. Furthermore, in some cases, we may not be able to obtain issued claims covering compositions relating to our core programs and product candidates, as well as other technologies that are important to our business, and instead may need to rely on filing patent applications with claims covering a method of use and/or method of manufacture for protection of such core programs, product candidates, and other technologies. Any changes we make to our product candidates to cause them to have what we view as more advantageous properties may not be covered by our existing patents and patent applications, and we may be required to file new applications and/or seek other forms of protection for any such altered product candidates. There can be no assurance that we would be able to secure patent protection that would adequately cover altered product candidates. There can be no assurance that any such patent applications will issue as granted patents, and even if they do issue, such patent claims may be insufficient to prevent third parties, such as our competitors, from utilizing our technology. Any failure to obtain or maintain patent protection with respect to our core programs and product candidates could have a material adverse effect on our business, financial condition, results of operations, and prospects.

If the scope of any patent protection we obtain is not sufficiently broad, or if we lose any of our patent protection, our ability to prevent our competitors from commercializing similar or identical technology and product candidates would be adversely affected.

The patent position of biopharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights are highly uncertain. Our pending and future patent

79

Table of Contents

applications may not result in patents being issued which protect our product candidates or other technologies or which effectively prevent others from commercializing competitive technologies and product candidates.

Moreover, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Patent applications we own currently or that in the future issue as patents may not be issued in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage. Any patents to which we have rights may be challenged, narrowed, circumvented, or invalidated by third parties. Consequently, we do not know whether product candidates or other technologies will be protectable or remain protected by valid and enforceable patents. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner which could materially adversely affect our business, financial condition, results of operations, and prospects.

The issuance of a patent is not conclusive as to its inventorship, scope, validity, or enforceability, and our patents may be challenged in the courts or patent offices in the United States and abroad. We may be subject to a third-party pre-issuance submission of prior art to the United States Patent and Trademark Office (USPTO) or post-issuance become involved in opposition, derivation, revocation, reexamination, post-grant and inter partes review, or interference proceedings or other similar proceedings challenging our patent rights. An adverse determination in any such submission, proceeding, or litigation could reduce the scope of, or invalidate or render unenforceable, such patent rights, allow third parties to commercialize our product candidates or other technologies and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. Moreover, we may have to participate in interference proceedings declared by the USPTO to determine priority of invention or in post-grant challenge proceedings, such as post-grant review at the USPTO or oppositions in a foreign patent office, that challenge our priority of invention or other features of patentability with respect to our patents and patent applications. Such challenges may result in loss of patent rights, loss of exclusivity, or in patent claims being narrowed, invalidated, or held unenforceable, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our product candidates and other technologies. Such proceedings also may result in substantial cost and require significant time from our scientists and management, even if the eventual outcome is favorable to us. If we are unsuccessful in any such proceeding or other priority or inventorship dispute, we may be required to obtain licenses from third parties, including parties involved in any such interference proceedings or other priority or inventorship disputes. Such licenses may not be available on commercially reasonable terms or at all, or may be non-exclusive. If we are unable to obtain and maintain such licenses, we may need to cease the development, manufacture, and commercialization of one or more of the product candidates we may develop. Termination of these licenses or reduction or elimination of our rights under these licenses may result in our having to negotiate new or reinstated agreements with less favorable terms, or cause us to lose our rights under these licenses, including our rights to important intellectual property or technology. The loss of exclusivity or the narrowing of our owned and licensed patent claims could limit our ability to stop others from using or commercializing similar or identical technology and products.

In addition, given the amount of time required for the development, testing, and regulatory review of new product candidates, patents protecting such product candidates might expire before or shortly after such product candidates are commercialized. As a result, our intellectual property may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Some of our patents and patent applications may in the future be co-owned with third parties. In addition, future collaborators or licensors may co-own their patents and patent applications with other third parties with whom we do not have a direct relationship. Our rights to certain of these patents and patent applications may be dependent, in part, on inter-institutional or other operating agreements between the joint owners of such patents and patent applications, who are not parties to our license agreements. If our future collaborators or licensors do not have exclusive control of the grant of licenses under any such third-party co-owners’ interest in such patents or patent applications or we are otherwise unable to secure such exclusive rights, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology to the extent such products and technology are not also covered by our intellectual property. In addition, we may need the cooperation of any such co-owners of our patents in order to enforce such patents against third parties, and such

80

Table of Contents

cooperation may not be provided to us. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.

If we are unable to obtain licenses from third parties on commercially reasonable terms or fail to comply with our obligations under such agreements, our business could be harmed.

It may be necessary for us to use the patented or proprietary technology of third parties to commercialize our products, in which case we would be required to obtain a license from these third parties. If we are unable to license such technology, or if we are forced to license such technology, on unfavorable terms, our business could be materially harmed. If we are unable to obtain a necessary license, we may be unable to develop or commercialize the affected product candidates, which could materially harm our business, and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us.

If we fail to comply with our obligations under our license agreements, our counterparties may have the right to terminate these agreements, in which event we might not be able to develop, manufacture or market, or may be forced to cease developing, manufacturing or marketing, any product that is covered by these agreements or may face other penalties under such agreements. Such an occurrence could materially adversely affect the value of the product candidate being developed under any such agreement. Termination of these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or reinstated agreements with less favorable terms, cause us to lose our rights under these agreements, including our rights to important intellectual property or technology, or impede, delay or prohibit the further development or commercialization of one or more product candidates that rely on such agreements.

Our rights to develop and commercialize our product candidates may be subject, in part, to the terms and conditions of agreements with others.

Agreements we may enter into in the future may not provide exclusive rights to use certain intellectual property and technology retained by the collaborator in all relevant fields of use and in all territories in which we may wish to develop or commercialize our technology and products in the future. As a result, we may not be able to prevent competitors or other third parties from developing and commercializing competitive products that utilize technology retained by such collaborators to the extent such products are not also covered by our intellectual property.

In addition, subject to the terms of any such agreements, we may not have the right to control the preparation, filing, prosecution, and maintenance, and we may not have the right to control the enforcement and defense of certain patents and patent applications retained by the collaborator and provided to us under a limited license. We cannot be certain that patents and patent applications that are controlled by future collaborators will be prepared, filed, prosecuted, maintained, enforced, and defended in a manner consistent with the best interests of our business. If our collaborators fail to prosecute, maintain, enforce, and defend such patents, or lose rights to those patents or patent applications, the limited rights we have licensed may be reduced or eliminated, our right to develop and commercialize any of our product candidates that are subject of such licensed rights could be adversely affected, and we may have a reduced ability to prevent competitors from making, using, and selling competing products. In addition, even where we have the right to control patent prosecution of patents and patent applications we have licensed to and from future collaborators, we may still be adversely affected or prejudiced by actions or inactions of future collaborators that took place prior to the date upon which we assumed control over patent prosecution.

We may enter into agreements with future collaborators to option or license certain intellectual property and may need to obtain additional intellectual property rights from others to advance our research or allow commercialization of product candidates we may develop. We may be unable to obtain additional intellectual property rights at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to expend significant time and resources to redesign our technology, product candidates, or the methods for manufacturing them or to develop or license replacement technology, all of which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates, which could harm our business, financial condition, results of operations, and prospects significantly. We cannot provide any assurances that third-party patents do not exist which might be enforced against our current technology, manufacturing methods, product

81

Table of Contents

candidates, or future methods or products resulting in either an injunction prohibiting our manufacture or future sales, or, with respect to our future sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties, which could be significant.

Furthermore, our or our future collaborators’ patents may be subject to a reservation of rights by one or more third parties. The U.S. government may have certain rights to resulting intellectual property. When new technologies are developed with U.S. government funding, the U.S. government generally obtains certain rights in any resulting patents, including a non-exclusive license authorizing the U.S. government to use the invention or to have others use the invention on its behalf. The U.S. government’s rights may also permit it to disclose the funded inventions and technology to third parties and to exercise march-in rights to use or allow third parties to use the technology developed using U.S. government funding. The U.S. government may exercise its march-in rights if it determines that action is necessary because we fail to achieve the practical application of the government funded technology, or because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in facilities in the United States in certain circumstances and if this requirement is not waived. Any exercise by the U.S. government of such rights or by any third-party of its reserved rights could have a material adverse effect on our competitive position, business, financial condition, results of operations, and prospects.

If we fail to comply with our obligations in agreements under which we option or license intellectual property rights from future collaborators or licensors or otherwise experience disruptions to our business relationships with future collaborators or licensors, we could lose intellectual property rights that are important to our business.

We may enter into agreements with future collaborators that impose various economic, development, diligence, commercialization, and other obligations on us. Such collaboration agreements may also require us to meet development timelines, or to exercise commercially reasonable efforts to develop and commercialize licensed products. Our future collaborators might conclude that we have materially breached our obligations under such agreements and might therefore terminate or seek damages under the agreements, thereby removing or limiting our ability to develop and commercialize products and technology covered by these agreements. Termination of these agreements could cause us to lose the rights to certain patents or other intellectual property, or the underlying patents could fail to provide the intended exclusivity, and competitors or other third parties may have the freedom to seek regulatory approval of, and to market, products similar to or identical to ours and we may be required to cease our development and commercialization of certain of our product candidates. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and growth prospects.

Moreover, disputes may arise regarding intellectual property subject to a collaboration agreement, including:

82

Table of Contents

We may enter into agreements to option or license intellectual property or technology from third parties that are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations, and growth prospects. Moreover, if disputes over intellectual property that we have optioned or licensed prevent or impair our ability to maintain such arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, which could have a material adverse effect on our business, financial conditions, results of operations, and growth prospects.

We may not be able to protect our intellectual property and proprietary rights throughout the world.

Filing, prosecuting, and defending patents on our product candidates and other technologies in all countries throughout the world would be prohibitively expensive, and the laws of foreign countries may not protect our rights to the same extent as the laws of the United States.

Consequently, we may not be able to prevent third parties from using our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products, and, further, may export otherwise infringing products to territories where we have patent protection but enforcement is not as strong as that in the United States. These products may compete with our products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets, and other intellectual property protection, particularly those relating to biopharmaceutical products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our intellectual property and proprietary rights generally. Proceedings to enforce our intellectual property and proprietary rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property and proprietary rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our future collaborators or licensors is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations, and prospects may be adversely affected.

Issued patents covering our product candidates and other technologies could be found invalid or unenforceable if challenged in court or before administrative bodies in the United States or abroad.

If we initiated legal proceedings against a third party to enforce a patent covering our product candidates or other technologies, the defendant could counterclaim that such patent is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. Third parties may raise claims challenging the validity or enforceability of our patents before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re-examination, post-grant review, inter partes review, interference proceedings, derivation proceedings, and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). Such proceedings could result in the

83

Table of Contents

revocation of, cancellation of, or amendment to our patents in such a way that they no longer cover our product candidates or other technologies. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a third-party were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our product candidates or other technologies. Such a loss of patent protection would have a material adverse impact on our business, financial condition, results of operations, and growth prospects.

Third-party claims of intellectual property infringement, misappropriation, or other violation against us may prevent or delay the development and commercialization of our product candidates and other technologies.

The fields of designing and developing treatments for immunology, inflammation, and metabolic diseases are highly competitive and dynamic. In addition, while research and development that is taking place by several companies, including us and our competitors in oral biologic therapeutics, the technology used in our product candidates is still in development and no products utilizing similar technology have yet reached the market. As such, it is difficult to conclusively assess our freedom to operate without infringing on third-party rights. This could lead to significant intellectual property related litigation and proceedings relating to our, and other third-party, intellectual property and proprietary rights in the future.

Our commercial success depends in part on our ability to develop, manufacture, market, and sell any product candidates that we develop and to use our proprietary technologies without infringing, misappropriating, and otherwise violating the patents and other intellectual property rights of third parties. There is a substantial amount of complex litigation involving patents and other intellectual property rights in the biotechnology and pharmaceutical industries, as well as administrative proceedings for challenging patents, including interference, post-grant review, inter partes review, derivation proceedings, and reexamination proceedings before the USPTO or oppositions and other comparable proceedings in foreign jurisdictions. We may become party to, or threatened with, such actions in the future, regardless of their merit.

Numerous U.S. and foreign issued patents and pending patent applications owned by third parties exist in the fields in which we are developing our product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates and other technologies may give rise to claims of infringement of the patent rights of others. We cannot assure you that our product candidates and other technologies that we have developed, are developing or may develop in the future will not infringe existing or future patents owned by third parties. We may not be aware of patents that have already been issued and that a third-party, for example, a competitor in the fields in which we are developing product candidates, and other technologies might assert are infringed by our current or future product candidates or other technologies, including claims to compositions, formulations, methods of manufacture or methods of use or treatment that cover our product candidates or other technologies. It is also possible that patents owned by third parties of which we are aware, but which we do not believe are relevant to our product candidates or other technologies, could be found to be infringed by our product candidates or other technologies. In addition, because patent applications can take many years to issue, there may be currently pending patent applications that may later result in issued patents that our product candidates or other technologies may infringe.

Third parties may have patents or obtain patents in the future and claim that the manufacture, use, or sale of our product candidates or other technologies infringes upon these patents. In the event that any third party claims that we infringe their patents or that we are otherwise employing their proprietary technology without authorization and initiates litigation against us, even if we believe such claims are without merit, a court of competent jurisdiction could hold that such patents are valid, enforceable and infringed by our product candidates or other technologies. In this case, the holders of such patents may be able to block our ability to commercialize the applicable product candidate or technology unless we obtain a license under the applicable patents, or until such patents expire or are finally determined to be held invalid or unenforceable. Such a license may not be available on commercially reasonable terms or at all. Even if we are able to obtain a license, the license would likely obligate us to pay license fees or royalties or both, and the rights granted to us might be nonexclusive, which could result in our competitors gaining access to the same intellectual property. If we are unable to obtain a necessary license to a third party patent on commercially reasonable terms, we may be unable to commercialize our product candidates or other technologies, or such commercialization efforts may be significantly delayed, which could in turn significantly harm our business.

84

Table of Contents

Defense of infringement claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of management and other employee resources from our business, and may impact our reputation. In the event of a successful claim of infringement against us, we may be enjoined from further developing or commercializing our infringing product candidates or other technologies. In addition, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties, and/or redesign our infringing product candidates or technologies, which may be impossible or require substantial time and monetary expenditure. In that event, we would be unable to further develop and commercialize our product candidates or other technologies, which could harm our business significantly.

Engaging in litigation to defend against third parties alleging that we have infringed, misappropriated, or otherwise violated their patents or other intellectual property rights is very expensive, particularly for a company of our size, and time-consuming. Some of our competitors may be able to sustain the costs of litigation or administrative proceedings more effectively than we can because of greater financial resources. Patent litigation and other proceedings may also absorb significant management time. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings against us could impair our ability to compete in the marketplace. The occurrence of any of the foregoing could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.

We may become involved in lawsuits to protect or enforce our patents and other intellectual property rights, which could be expensive, time consuming, and unsuccessful.

Competitors may infringe our patents or we may be required to defend against claims of infringement. In addition, our patents may become involved in inventorship, priority, or validity disputes. To counter or defend against such claims can be expensive and time consuming. In an infringement proceeding, a court may decide that a patent in which we have an interest is invalid or unenforceable, the other party’s use of our patented technology falls under the safe harbor to patent infringement under 35 U.S.C. §271(e)(1), or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions, or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing, or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.

Patent terms may be inadequate to protect our competitive position on our products and services for an adequate amount of time.

Patents have a limited lifespan. In the United States and abroad, if all maintenance fees/annuity fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest non-provisional filing date. The protection a patent affords is limited. Even if patents covering our products are obtained, once the patent life has expired, we may be open to competition from competitive products. Given the amount of time required for the development, testing, and regulatory review of new products, patents protecting such products might expire before or shortly after such products are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.

We may be subject to claims that former employees or other third parties have an interest in our patents, trade secrets, or other intellectual property as an inventor or co-inventor. For example, our Co-Founder and Chief Scientific Officer, Dr. Randall Mrsny, has been and remains an employee of both our company and the University of Bath, and as such, we must ensure that we own our intellectual property that is conceived or developed by Dr. Mrsny and that which he is under obligation to assign to our company. We may have inventorship or ownership disputes arise from conflicting obligations of our founders, employees, consultants, or others who are involved in developing our product candidates or other technologies, such as with the University of Bath. Litigation may be necessary to defend against any claims challenging inventorship or ownership of our patents, trade secrets, or other intellectual property. If the defense of any such claims fails, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property that is important to our product candidates and other technologies. Even if we are successful in defending against any such claims, litigation could result in substantial costs and be a distraction to management and other employees. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.

If we do not obtain patent term extension and data exclusivity for any product candidates we may develop, our business may be materially harmed.

Depending upon the timing, duration, and specifics of any FDA marketing approval of any product candidates we may develop, one or more of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984 (Hatch-Waxman Act). The Hatch-Waxman Act permits a patent term extension of up to five years as compensation for patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. Similar extensions as compensation for patent term lost during regulatory review processes are also available in certain foreign countries and territories, such as in Europe under a Supplementary Patent Certificate. However, we may not be granted an extension in the United States and/or foreign countries and territories because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain patent term extension or the term of any such extension is shorter than what we request, our competitors may obtain approval of competing products following our patent expiration, and our business, financial condition, results of operations, and growth prospects could be materially harmed.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patents for our product candidates and other technologies, we also rely on trade secrets and confidentiality agreements to protect our unpatented know-how, technology, and other proprietary information and to maintain our competitive position. We consider trade secrets and know-how to be one of our primary sources of intellectual property. Trade secrets and know-how can be difficult to protect. We expect our trade secrets and know-how to over time be disseminated within the industry through independent development, the publication of journal articles describing the methodology, and the movement of personnel from academic to industry scientific positions.

While we seek to protect these trade secrets and other proprietary technology, we cannot guarantee that we have entered into non-disclosure, confidentiality, invention, or patent assignment agreements with each party that may have or have had access to our trade secrets or proprietary technology and processes. Despite our efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive, and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third-party, we would have no right to prevent them from using that technology or information to compete with us. If any of our trade

86

Table of Contents

secrets were to be disclosed to or independently developed by a competitor or other third-party, our competitive position would be materially and adversely harmed.

If any of our patent applications do not issue as patents in any jurisdiction, we may not be able to compete effectively.

Changes in either the patent laws or their interpretation in the United States and other countries may diminish our ability to protect our inventions, obtain, maintain, and enforce our intellectual property rights and, more generally, could affect the value of our intellectual property or narrow the scope of our patents with respect to our product candidates. With respect to our intellectual property related to our product candidates, we cannot predict whether the patent applications we are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient protection from competitors or other third parties.

The patent prosecution process is expensive, time-consuming, and complex, and we may not be able to file, prosecute, maintain, enforce, or license all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output in time to obtain patent protection. We may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the rights to patents licensed to third parties. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. Any parties who enter into nondisclosure and confidentiality agreements with us who have access to confidential or patentable aspects of our research and development output, such as our employees, CROs, CDMOs, consultants, advisors, and other third parties, may breach the agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. In addition, our ability to obtain and maintain valid and enforceable patents depends on whether the differences between our inventions and the prior art allow our inventions to be patentable over the prior art. Furthermore, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in any of our patents or pending patent applications, or that we were the first to file for patent protection of such inventions.

Intellectual property rights do not necessarily address all potential threats.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

Should any of these events occur, it or they could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees, and various other government fees on patents and applications will be due to be paid to the USPTO and various government patent agencies outside of the United States over the lifetime of our owned or licensed patents and applications. The USPTO and various non-U.S. government agencies require compliance with several procedural, documentary, fee payment, and other similar provisions during the patent application process. There are situations, however, in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in a partial or complete loss of patent rights in the relevant jurisdiction. In such an event, potential competitors might be able to enter the market with similar or identical products or technology, which could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.

Changes in patent law in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.

Changes in either the patent laws or interpretation of the patent laws in the United States or other jurisdictions could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. Assuming that other requirements for patentability are met, prior to March 16, 2013, in the United States, the first to invent the claimed invention was entitled to the patent, while outside the United States, the first to file a patent application was entitled to the patent. On or after March 16, 2013, under the Leahy-Smith America Invents Act (the America Invents Act) enacted on September 16, 2011, the United States transitioned to a first inventor to file system in which, assuming that other requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third-party was the first to invent the claimed invention. A third-party that files a patent application in the USPTO on or after March 16, 2013, but before us could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third-party. This will require us to be cognizant going forward of the time from invention to filing of a patent application. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we were the first to either (i) file any patent application related to our product candidates or other technologies or (ii) invent any of the inventions claimed in our patents or patent applications.

Table of Contents

The America Invents Act also includes a number of significant changes that affect the way patent applications will be prosecuted and also may affect patent litigation. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third-party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third-party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third-party as a defendant in a district court action. Therefore, the America Invents Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

In addition, the patent positions of companies in the development and commercialization of biopharmaceuticals are particularly uncertain. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the validity and enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future.

We may be subject to claims that our employees, consultants, or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property.

Many of our employees, consultants, and advisors are currently or were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors and potential competitors. Although we try to ensure that our employees, consultants, and advisors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these individuals have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented, or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential partners or customers in our markets of interest. At times, competitors or other third parties may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trademarks, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could

89

Table of Contents

result in substantial costs and diversion of resources and could adversely affect our business, financial condition, results of operations, and growth prospects. In addition, opposition or cancellation proceedings may be filed against our trademark applications and registrations, and our trademarks may not survive such proceedings. In certain countries outside of the United States, trademark registration is required to enforce trademark rights. If we do not secure registrations for our trademarks, we may encounter more difficulty in enforcing them against third parties than we otherwise would.

Risks Related to Our Operations

We are highly dependent on our key personnel, and if we are not successful in attracting, motivating, and retaining highly qualified personnel, we may not be able to successfully implement our business strategy.

Our ability to compete in the highly competitive biotechnology and pharmaceutical industries depends upon our ability to attract, motivate, and retain highly qualified managerial, scientific, and clinical development personnel. We are highly dependent on our management and our scientific, technical, business, and medical personnel. The loss of the services provided by any of our executive officers, other key employees, and other scientific and medical advisors, and our inability to find suitable replacements, could result in delays in the development of our product candidates and harm our business. Additionally, the COVID-19 pandemic and/or the highly competitive job market has interfered with our ability to hire or retain personnel and we have been required to increase our compensation and incentive packages, and be more flexible in allowing personnel to work remotely from other cities to attract and retain personnel.

We conduct our operations at our facility in South San Francisco, California, in a region that is headquarters to many other biopharmaceutical companies and many academic and research institutions. To succeed, we must recruit, retain, manage and motivate qualified clinical, scientific, manufacturing, and sales and marketing personnel, and we face significant competition for experienced personnel. In addition, we will need to expand and effectively manage our managerial, operational, financial, development and other resources in order to successfully pursue our research, development and commercialization efforts for our existing and future product candidates. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited talent pool in our industry due to the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize products. Competition for skilled personnel is intense and the turnover rate can be high, which may limit our ability to hire and retain highly qualified personnel on acceptable terms or at all. We expect that we may need to recruit talent from outside of our region, and doing so may be costly and difficult.

Many of the other biotechnology companies that we compete against for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better prospects for career advancement. Some of these characteristics may be more appealing to high-quality candidates than what we can offer. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition to competition for personnel, the San Francisco Bay Area in particular is characterized by a high cost of living. We could in the future have difficulty attracting experienced personnel to our company and may be required to expend significant financial resources in our employee recruitment and retention efforts. To induce valuable employees to remain at our company, in addition to salary and cash incentives, we have provided equity grants that vest over time. The value to employees of these equity grants that vest over time have been and may continue to be significantly affected by movements in our stock price that are beyond our control, and may at any time be insufficient to counteract more lucrative offers from other companies. Although we have employment agreements with our key employees, these employment agreements provide for at-will employment, which means that any of our employees could leave our employment at any time, with or without notice. If we are unable to attract and incentivize quality personnel on acceptable terms, or at all, it may cause our business and operating results to suffer.

Future strategic partnerships and collaborations may be important to us. We will face significant competition in seeking new strategic partners.

We have limited capabilities for manufacturing and do not yet have any capability for sales, marketing or distribution. For some of our product candidates, we may in the future determine to collaborate with pharmaceutical and biotechnology companies for development and potential commercialization of therapeutic products. The competition for strategic partners is intense. Our ability to reach a definitive agreement for collaboration will depend, among other

90

Table of Contents

things, upon our assessment of the strategic partner’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed strategic partner’s evaluation of a number of factors. These factors may include the design or results of clinical trials, the likelihood of approval by the FDA or comparable foreign regulatory authorities, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, and industry and market conditions generally. The strategic partner may also consider alternative product candidates or technologies for similar indications that may be available for collaboration and whether such collaboration could be more attractive than the one with us for our product candidate.

Strategic partnerships are complex and time-consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future strategic partners. Even if we are successful in entering into collaboration, the terms and conditions of that collaboration may restrict us from entering into future agreements with other potential collaborators.

If we are unable to reach agreements with suitable strategic partners on a timely basis, on acceptable terms, or at all, we may have to curtail the development of a product candidate, reduce or delay one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into strategic partnerships and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our product candidates or bring them to market or continue to develop our technology platform and our business may be materially and adversely affected. Any collaboration may be on terms that are not optimal for us, and we may not be able to maintain any new collaboration if, for example, development or approval of a product candidate is delayed, sales of an approved product candidate do not meet expectations or the partner terminates the collaboration. Any such collaboration, or other strategic transaction, may require us to incur non-recurring or other charges, and increase our near- and long-term expenditures and pose significant integration or implementation challenges or disrupt our management or business. Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, any transactions that we do complete may be subject to the foregoing or other risks and have a material and adverse effect on our business, financial condition, results of operations, and prospects. Conversely, any failure to enter any collaboration or other strategic transaction that would be beneficial to us could delay the development and potential commercialization of our product candidates and have a negative impact on the competitiveness of any product candidate that reaches the market.

If we are unable to maintain future strategic partnerships, or if these strategic partnerships are not successful, our business could be adversely affected.

Any future strategic partnerships we enter into may pose a number of risks, including the following:

91

Table of Contents

We may in the future engage in acquisitions, collaborations, or strategic partnerships, which may increase our capital requirements, dilute our stockholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks.

We may engage in various acquisitions, collaborations, and strategic partnerships in the future, including licensing or acquiring complementary products, intellectual property rights, technologies, or businesses. Any acquisition, collaboration, or strategic partnership may entail numerous risks, including:

92

Table of Contents

In addition, if we undertake such a transaction, we may issue dilutive securities, assume or incur debt obligations, incur large one-time expenses, and acquire intangible assets that could result in significant future amortization expense.

Any legal proceedings or claims against us could be costly and time-consuming to defend and could harm our reputation regardless of the outcome.

We are and may in the future become subject to legal proceedings and claims that arise in the ordinary course of business, including intellectual property, product liability, employment, class action, whistleblower and other litigation claims, and governmental and other regulatory investigations and proceedings. Such matters can be time-consuming, divert management’s attention and resources, cause us to incur significant expenses or liability, or require us to change our business practices. In addition, the expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change, and could adversely affect our financial condition and results of operations. Because of the potential risks, expenses, and uncertainties of litigation, we may, from time to time, settle disputes, even where we have meritorious claims or defenses, by agreeing to settlement agreements. Any of the foregoing could adversely affect our business, financial condition, and results of operations.

Our business is subject to economic, political, regulatory, and other risks associated with international operations.

Our business is subject to risks associated with conducting business internationally. Some of our CDMOs are located outside the United States. Accordingly, our future results could be harmed by a variety of factors, including:

These and other risks associated with our planned international operations may materially adversely affect our ability to attain profitable operations.

Our internal computer systems, or those used by our CROs or other contractors or consultants, may fail or suffer other breakdowns, cyberattacks, or information security breaches or incidents that could compromise the confidentiality, integrity, and availability of such systems and data, and affect our reputation.

Despite the implementation of security measures, our internal computer systems and those of our future CROs and other contractors may be vulnerable to damage, compromise, disruption and unauthorized access owing to a variety of causes, including system malfunction, natural disasters, terrorism, war and telecommunication and electrical failure, and inadvertent or intentional actions by our employees, CROs and other contractors, and/or other third parties, or cyber-attacks by malicious third parties. As the cyber-threat landscape evolves, such cyberattacks are growing in frequency, sophistication, and intensity, and are becoming increasingly difficult to detect. Such attacks could include the use of key loggers or other harmful and virulent malware, including ransomware or other denials of service, and can be deployed through malicious websites, the use of social engineering, and/or other means. These risks may increase as a result of COVID-19, owing to an increase in our and our CROs’ and other contractors’ personnel working remotely or utilizing personal devices. If a breakdown, disruption, cyberattack, or other information security breach or security incident were to occur and cause interruptions in our operations or loss, corruption, or unavailability of data, or if any of the foregoing were perceived to have occurred, it could subject us to claims, proceedings, or other liabilities and may result in a material disruption of our development programs and our business operations, which could lead to significant delays or setbacks in our research and other further development and commercialization of our product candidates. For example, the loss of clinical trial data from completed, ongoing, or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Furthermore, disruptions of, or security breaches or other incidents of, our information technology systems or those of our future CROs and other contractors and consultants could result in the loss, misappropriation, and/or unauthorized access, use, or disclosure or dissemination of, or the prevention of access to, data (including trade secrets or other confidential information, intellectual property, proprietary business information, and personal information), which could result in financial, legal, business, and reputational harm to us. For example, any such event that leads to loss, damage, or unavailability of, or unauthorized access to, or use, alteration, or disclosure or dissemination of, personal information or other data we or our contractors or consultants process or maintain, including personal information regarding clinical trial subjects or employees, could harm our reputation directly, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatory corrective action, and otherwise subject us to liability under laws and regulations that protect the privacy and security of personal information, which could result in significant legal and financial exposure and reputational damages that could potentially have an adverse effect on our business.

We also rely on third parties to manufacture our product candidates, and similar events relating to their information technology systems could also have a material adverse effect on our business. There can be no assurance that we, our CROs or other contractors, or our business counterparts will be successful in efforts to detect, prevent, or fully recover systems or data, including data or information that we process or maintain or that is processed or maintained by our CROs, other contractors, or business counterparts, from all breakdowns, service interruptions, or attacks on, or breaches or incidents of systems that could adversely affect our business and operations and/or result in the loss, corruption, or unavailability of data or other information, or inappropriate disclosure or dissemination of any such information, or events or circumstances leading to the perception that any of these have occurred, which could result in financial, legal, business, or reputational harm to us, including claims, litigation, governmental investigations and proceedings, and fines, penalties, and other liabilities. Further, notification and follow-up actions related to a security incident could impact our reputation and cause us to incur significant costs, including legal expenses and remediation costs. We expect to incur significant costs in an effort to detect and prevent security breaches and incidents, and we may face increased costs and requirements to expend substantial resources in the event of an actual or perceived security breach or other security incident.

The insurance we maintain may not be adequate to compensate us for the potential losses arising from any such disruption in or, failure or security breach or incident of or impacting, our systems or third-party systems where information important to our business operations or commercial development is stored. In addition, such insurance may not be available to us in the future on economically reasonable terms, or at all. Further, our insurance may not

94

cover all claims made against us and could have high deductibles in any event, and defending a suit, regardless of its merit, could be costly and divert management attention.

Risks Related to Ownership of Our Common Stock

The market price of our common stock may be volatile, which could result in substantial losses for investors.

The trading price of our common stock has been and may continue to be highly volatile and subject to wide fluctuation in response to various factors, some of which are beyond our control. Some of the factors that may cause the market price of our common stock to fluctuate include:

95

Table of Contents

Recently, the market price of our common stock has been volatile. In addition, in recent years, the stock market in general, and the market for pharmaceutical and biotechnology companies in particular, has experienced significant price and volume fluctuations that have often been unrelated or disproportionate to changes in the operating performance of the companies whose stock is experiencing those price and volume fluctuations. Broad market and industry factors may seriously affect the market price of our common stock, regardless of our actual operating performance. Following periods of such volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Because of the potential volatility of our stock price, we may become the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management’s attention and resources from our business which could seriously harm our business.

An active trading market of our common stock may not be sustained.

Prior to the closing of our IPO in June 2020, there was no public trading market for our common stock. Although our common stock is listed on the Nasdaq Global Select Market, the market for our shares has demonstrated varying levels of trading activity. We cannot predict the prices at which our common stock will trade. It is possible that in one or more future periods our results of operations and progression of our product pipeline may not meet the expectations of public market analysts and investors, and, as a result of these and other factors, the price of our common stock may fall.

If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our stock, the price of our stock could decline.

The trading market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our business. If one or more of the analysts covering our business downgrade their evaluations of our stock or if we fail to meet their operating results estimates for us, the price of our stock could decline. If one or more of these analysts cease to cover our stock, we could lose visibility in the market for our stock, which in turn could cause our stock price to decline.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. On July 1, 2021, we filed an omnibus shelf registration statement on Form S-3 with the SEC that automatically became effective and allows us to undertake various equity and debt offerings, and on January 28, 2022, we filed a prospectus supplement to the shelf registration statement that covers the offering, issuance and sale of up to $150 million of our common stock from time to time through an “at-the-market” program under the Securities Act of 1933, as amended. If we or our stockholders sell, or the market perceives that our stockholders intend to sell, substantial amount of our common stock in the public market, the market price of our common stock could decline significantly.

Moreover, certain holders of shares of our common stock have rights, subject to conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or other stockholders. Registration of these shares under the Securities Act of 1933, as amended (Securities Act) would result in the shares becoming freely tradeable in the public market, subject to the restrictions of Rule 144 in the case of our affiliates. If any of these additional shares are sold, or if it is perceived that they will be sold, in the public market, the market price of our common stock could decline.

Raising additional capital may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.

We have in the past and may in the future seek additional capital through a combination of public and private equity offerings, debt financings, strategic partnerships and alliances, and licensing arrangements. For example, on April 6, 2021, we completed a follow-on offering and issued 2,875,000 shares of our common stock at a price of $42.00 per share. In addition, on July 1, 2021, we filed an omnibus shelf registration statement on Form S-3 with the SEC that automatically became effective and allows us to undertake various equity and debt offerings, and on January 28, 2022, we filed a prospectus supplement to the shelf registration statement that covers the offering, issuance and sale of up to $150 million of our common stock from time to time through an “at-the-market” program under the Securities Act of 1933, as amended. We, and indirectly, our stockholders, will bear the cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing, or nature of any future offerings. To the extent that we raise additional capital through the sale of equity or debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of indebtedness would result in increased fixed payment obligations and could involve restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell, or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Additionally, any future collaborations we enter into with third parties may provide capital in the near term but limit our potential cash flow and revenue in the future. If we raise additional funds through strategic partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms unfavorable to us.

Our principal stockholders and management own a significant percentage of our stock and will be able to exert significant control over matters subject to stockholder approval.

As of December 31, 2021, our executive officers, directors, holders of 5% or more of our capital stock and their respective affiliates beneficially owned approximately 46% of our voting stock. As a result, this group of stockholders, if they act together, will have the ability to control us through this ownership position. These stockholders may be able to determine all matters requiring stockholder approval. For example, these stockholders may be able to control elections of directors, amendments of our organizational documents or approval of any merger, sale of assets or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common stock that you may feel are in your best interest as one of our stockholders. The interests of this group of stockholders may not always coincide with your interests or the interests of other stockholders and they may act in a manner that advances their best interests and not necessarily those of other stockholders, including seeking a premium value for their common stock, which might affect the prevailing market price for our common stock.

We have incurred and will continue to incur increased costs as a result of operating as a public company, and our management has devoted and will continue to devote substantial time to new compliance initiatives and corporate governance practices.

As a public company, we have incurred and will continue to incur significant legal, accounting, and other expenses that we did not incur as a private company. SOX, the Dodd-Frank Wall Street Reform, and Consumer Protection Act, the listing requirements of the Nasdaq Stock Market, and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. We expect that we will need to hire additional accounting, finance, and other personnel in connection with our efforts to comply with the requirements of being a public company, and our management and other personnel will need to continue to devote a substantial amount of time towards maintaining compliance with these requirements. These requirements have increased and will continue to increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect that the rules and regulations applicable to us as a public company may make it more difficult and more expensive for us to obtain director and officer liability insurance, which could make it more difficult for us to attract and retain qualified members of our board of directors. We are currently evaluating these rules and regulations and cannot predict or estimate the amount of additional costs we may incur or the timing of such costs. These rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

Pursuant to SOX Section 404, we are required to furnish a report by our management on our internal control over financial reporting. We are also required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. To achieve compliance with SOX Section 404 within the prescribed period, we have engaged outside consultants and have been engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, work with outside consultants, adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented, and implement a continuous reporting and improvement process for internal control over financial reporting. If we identify one or more material weaknesses, it could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.

In addition, we are no longer an “emerging growth company” and may no longer take advantage of certain exemptions from various reporting requirements that are applicable to other public companies. This increase in reporting requirements will further increase our compliance burden.

If we are unable to maintain effective internal controls, our business, financial position, and results of operations could be adversely affected.

As a public company, we are subject to reporting and other obligations under the Securities Exchange Act of 1934, as amended (Exchange Act), including the requirements of SOX Section 404, which require annual management assessments of the effectiveness of our internal control over financial reporting. In addition, our auditors are required to formally attest to the effectiveness of our internal control over financial reporting pursuant to SOX Section 404.

The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation to meet the detailed standards under the rules. During the course of its testing, our management may identify material weaknesses or deficiencies which may not be remedied in time to meet the deadline imposed by SOX. These reporting and other obligations place significant demands on our management and administrative and operational resources, including accounting resources.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with

98

Table of Contents

accounting principles generally accepted in the United States. However, we have in the past and may in the future identify material weaknesses or significant deficiencies in internal control over financial reporting. Under standards established by the Public Company Accounting Oversight Board, a deficiency in internal control over financial reporting exists when the design or operation of a control does not allow management or personnel, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. A material weakness is a deficiency or combination of deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected and corrected on a timely basis. We cannot assure you that there will not be additional material weaknesses or significant deficiencies that our independent registered public accounting firm or we will identify.

If we are unable to successfully maintain internal control over financial reporting, or identify any additional material weaknesses, the accuracy and timing of our financial reporting may be adversely affected. In addition, if we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, when required, investors may lose confidence in the accuracy and completeness of our financial reports, we may face restricted access to the capital markets, and our stock price may be materially adversely affected. Moreover, we could become subject to investigations by regulatory authorities, which could require additional financial and management resources.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

As a public company, we are subject to the periodic reporting requirements of the Exchange Act. We designed our disclosure controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the fact that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

Delaware law and provisions in our amended and restated certificate of incorporation and bylaws might discourage, delay, or prevent a change in control of our company or changes in our management and, therefore, depress the trading price of our common stock.

Provisions in our amended and restated certificate of incorporation and bylaws may discourage, delay, or prevent a merger, acquisition, or other change in control that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares of our common stock. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management. Therefore, these provisions could adversely affect the price of our common stock. Among other things, our charter documents:

Table of Contents

In addition, Section 203 of the General Corporation Law of the State of Delaware (DGCL), prohibits a publicly-held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person which together with its affiliates owns, or within the last three years has owned, 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner.

Any provision of our amended and restated certificate of incorporation, amended and restated bylaws, or Delaware law that has the effect of delaying or preventing a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our capital stock and could also affect the price that some investors are willing to pay for our common stock.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our amended and restated bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the exclusive forum for (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders, (iii) any action arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws (as either may be amended from time to time), or (iv) any action asserting a claim governed by the internal affairs doctrine, except, in each case, (A) any claim as to which such court determines that there is an indispensable party not subject to the jurisdiction of such court (and the indispensable party does not consent to the personal jurisdiction of such court within ten days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum other than such court, or (C) for which such court does not have subject matter jurisdiction.

These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, employees, control persons, underwriters, or agents, which may discourage lawsuits against us and our directors, employees, control persons, underwriters, or agents. Additionally, a court could determine that the exclusive forum provision is unenforceable, and our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find these provisions of our amended and restated bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition, or results of operations.

General Risk Factors

Changes in interpretation or application of generally accepted accounting principles may adversely affect our operating results.

We prepare our financial statements to conform to United States Generally Accepted Accounting Principles. These principles are subject to interpretation by the Financial Accounting Standards Board, American Institute of Certified Public Accountants, the Public Company Accounting Oversight Board, the Securities and Exchange Commission and various other regulatory or accounting bodies. A change in interpretations of, or our application of, these principles can have a significant effect on our reported results and may even affect our reporting of transactions completed before a change is announced. Additionally, as we are required to adopt new accounting standards, our methods of accounting for certain items may change, which could cause our results of operations to fluctuate from period to period.

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.

Our operations, and those of our CROs, CDMOs, suppliers, and other contractors and consultants, could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, medical or health epidemics, and other natural or man-made disasters or business interruptions, for which we are partly uninsured. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. We rely on third-party manufacturers to produce and process our product candidates. Our ability to obtain clinical supplies of our product candidates could be disrupted if the operations of these suppliers are affected by a man-made or natural disaster or other business interruption.

The majority of our operations including our corporate headquarters and manufacturing operations are located in a facility in South San Francisco, California. Damage or extended periods of interruption to our corporate, development, research, or manufacturing facility due to fire, natural disaster, power loss, communications failure, unauthorized entry, or other events could cause us to cease or delay development of some or all of our product candidates. Although we maintain property damage and business interruption insurance coverage on our facility, our insurance might not cover all losses under such circumstances and our business may be seriously harmed by such delays and interruption.

We do not expect to pay any dividends for the foreseeable future. Investors may never obtain a return on their investment.

You should not rely on an investment in our common stock to provide dividend income. We do not anticipate that we will pay any dividends to holders of our common stock in the foreseeable future. Instead, we plan to retain any earnings to maintain and expand our existing operations. In addition, any future credit facility may contain terms prohibiting or limiting the amount of dividends that may be declared or paid on our common stock. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any return on their investment. As a result, investors seeking cash dividends should not purchase our common stock.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Our corporate headquarters is currently located in South San Francisco, California, where we lease 84,321 square feet of laboratory, manufacturing, warehouse and office space pursuant to a lease agreement that expires in October 2029. We also lease approximately 20,000 square feet of additional warehouse space in South San Francisco, California pursuant to a lease agreement that expires in July 2029.

We believe that these facilities will be adequate for our near-term needs. If required, we believe that suitable additional or alternative space would be available in the future on commercially reasonable terms.

Item 3. Legal Proceedings.

From time to time, we may become involved in litigation or other legal proceedings arising in the ordinary course of our business. We are not currently, and were not during the year ended December 31, 2021, a party to any litigation or legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business and, to the best of management’s knowledge, no such litigation is currently pending or threatened. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, negative publicity, reputational harm and other factors.

Use of Proceeds from Public Offering of Common Stock

On June 4, 2020, our registration statement on Form S-1 was declared effective by the SEC for our initial public offering of common stock. We began trading on the Nasdaq Global Select Market on June 5, 2020, and the transaction formally closed on June 9, 2020. In connection with our IPO, we issued and sold an aggregate of 12,650,000 shares of our common stock at a price of $14.00 per share, including 1,650,000 shares of our common stock issued and sold in connection with the full exercise by the underwriters of their option to purchase additional shares of common stock. The aggregate offering price for shares sold in our IPO was $177.1 million. The joint book-running managers for the initial public offering were BofA Securities, Inc., Jefferies LLC, and SVB Leerink LLC. After deducting underwriting discounts and commissions and offering costs paid by us of approximately $16.5 million, the net proceeds from the offering were approximately $160.6 million. No payments were made by us to directors, officers or persons owning ten percent or more of our common stock or to their associates, or to our affiliates, other than payments in the ordinary course of business to officers for salaries and to non-employee directors pursuant to our director compensation policy.

There has been no material change in the planned use of proceeds in our IPO as described in our final prospectus filed with the SEC on June 5, 2020 pursuant to Rule 424(b)(4). We invested the funds received in interest-bearing investment-grade securities.

Use of Proceeds from Follow-On Offering

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing elsewhere in this Annual Report. This section of this Form 10-K generally discusses 2021 and 2020 items and year-to-year comparisons between 2021 and 2020. Discussions of 2019 items and year-to-year comparisons between 2020 and 2019 are not included in this Form 10-K, and can be found in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020. This discussion contains forward-looking statements that involve risks and uncertainties, including those described in the section titled “Special Note Regarding Forward Looking Statements.” Our actual results and the timing of selected events could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those set forth under the section titled “Risk Factors” included elsewhere in this report.

Overview

We are a clinical-stage biopharmaceutical company leveraging our proprietary technology platform to design and develop a pipeline of novel oral biologic product candidates to treat autoimmune, inflammatory, metabolic, and other diseases. Our proprietary technology platform allows us to exploit existing natural cellular trafficking pathways to facilitate the active transport of diverse therapeutic payloads across the IE barrier. Active transport is an efficient mechanism that uses the cell’s own machinery to transport materials across the IE barrier. We believe that our ability to exploit this mechanism is a key differentiator of our approach. We are developing oral biologic product candidates in patient-friendly dosage forms that are designed for either targeting local GI tissue or entering systemic circulation to precisely address the relevant biology of a disease. We are building a portfolio of oral product candidates based on our technology platform including our most advanced product candidate, AMT-101, a gastrointestinal (GI)-selective oral fusion of interleukin-10 (IL-10) and our proprietary carrier molecule. We are actively enrolling and dosing patients globally across multiple Phase 2 clinical trials of AMT-101 in ulcerative colitis (UC) and other inflammatory indications following the completion of a Phase 1b clinical trial in patients with UC. Our second product candidate, AMT-126, is a GI-selective oral fusion of interleukin-22 (IL-22) and our proprietary carrier molecule currently in development for diseases related to intestinal epithelial (IE) barrier function defects driven by activation of the innate immune system. We are currently enrolling subjects in a Phase 1 clinical trial with AMT-126. Our technology platform enables us to design and develop various oral biologic therapeutic modalities, such as peptides, proteins, full-length antibodies, antibody fragments, and RNA therapeutics, with potentially significant advantages over existing marketed and development-stage drugs.

Since the date of our incorporation in Delaware on November 21, 2016, we have devoted substantial resources to research and development activities, including research activities such as drug discovery, preclinical studies, and clinical trials as well as development activities such as the manufacturing of clinical and research material, establishing and maintaining our intellectual property portfolio, hiring personnel, raising capital, and providing general and administrative support for these operations.

We do not currently have any products approved for sale, and we have not generated any revenue from product sales. Our ability to generate product revenue sufficient to achieve profitability, if ever, will depend on the successful development of one or more of our product candidates which we expect will take a number of years. Given our stage of development, we have not yet established a commercial organization or distribution capabilities. We intend to build a commercial infrastructure to support sales of our product candidates. We expect to manage sales, marketing and distribution through internal resources and third-party relationships. While we may commit significant financial and management resources to commercial activities, we may also consider collaborating with one or more pharmaceutical companies to enhance our commercial capabilities.

Manufacturing of protein therapeutics is a complex process and represents a critical path to creating oral biologic therapeutics and a key component of our long-term success. We have spent significant resources to date on developing our current manufacturing processes and know-how to produce sufficient supply and optimize functionality. We now manufacture clinical supply at a new facility located in South San Francisco. While we have successfully manufactured clinical supply at our internal facility, we may need to scale our manufacturing operations to manufacture sufficient quantity needed to advance any of our product candidates in preclinical studies and clinical trials. Accordingly, we

105

Table of Contents

will be required to make significant investments to expand our manufacturing facilities in the future, and our efforts to scale our internal manufacturing capabilities are subject to risks.

In addition, even after the completion of our in-house manufacturing facility, we expect to continue to rely on third parties for the manufacture of our product candidates for preclinical and clinical testing, as well as for commercial manufacture if any of our product candidates obtain marketing approval. We also rely, and expect to continue to rely, on third parties to package, label, store and distribute our product candidates, as well as for our commercial products if marketing approval is obtained. We believe that this strategy allows us to maintain a more efficient infrastructure by eliminating the need for us to invest in our own manufacturing facilities, equipment and personnel while also enabling us to focus our expertise and resources on the development of our product candidates.

Since the date of our incorporation, we have incurred significant losses and negative cash flows from operations. During the year ended December 31, 2021, we incurred a net loss of $100.3 million and used $82.6 million of cash in operations. As of December 31, 2021, we had an accumulated deficit of $239.6 million and do not expect positive cash flows from operations in the foreseeable future. We expect to continue to incur significant and increasing losses for the foreseeable future, and our net losses may fluctuate significantly from period to period, depending on the timing of and expenditures on our planned research and development activities.

To date, we have financed our operations primarily through the private placements of convertible preferred stock and the issuance of common stock upon the completion of our IPO. We completed our IPO in June 2020 and received net proceeds of approximately $160.6 million after deducting underwriting discounts and commissions and offering costs, net of offering costs of $0.2 million paid in 2019. On April 6, 2021, we completed a follow-on offering and received net proceeds of approximately $112.8 million after deducting underwriting discounts and commissions and offering costs. In addition, on January 27, 2022, the Company entered into a Sales Agreement with SVB Leerink LLC and JMP Securities LLC, as the Company’s sales agents (the “Agents”), pursuant to which the Company may offer and sell from time to time through the Agents up to $150 million in shares of the Company’s common stock through an “at-the-market” program.

We expect our expenses will increase significantly in connection with our ongoing activities, as we:

As a result, we will require substantial additional capital to develop our product candidates and fund operations for the foreseeable future. Until such time as we can generate sufficient revenue from product sales, if ever, we expect to finance our operations through a combination of public or private equity offerings, debt financings, collaborations and licensing arrangements. We may be unable to raise additional funds or to enter into such agreements or arrangements on favorable terms, or at all. Our failure to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on our business, results of operations or financial condition, and could force us to delay, reduce or eliminate our drug development or future commercialization efforts. We may also be required to grant rights to develop and market drug candidates that we would otherwise prefer to develop and market ourselves. The amount and

106

Table of Contents

timing of our future funding requirements will depend on many factors including the pace and results of our development efforts. We cannot assure you that we will ever be profitable or generate positive cash flow from operating activities.

Based on our current operating plan, we believe that our existing cash, cash equivalents, and investments will be sufficient to fund our planned operations through at least the next 12 months from the date of issuance of these financial statements. We have based this projection on assumptions that may be inaccurate and as a result, we may utilize our capital resources sooner than we expect.

COVID-19

Our financial results could be affected by the COVID-19 pandemic in various ways. As a result of the COVID-19 pandemic, we have experienced and could experience disruptions that could severely impact our business, current and planned critical trials and preclinical studies. For example, the COVID-19 pandemic could result in delays to our clinical trials and preclinical studies for numerous reasons including difficulties in enrolling patients or healthy volunteers, diversion of healthcare resources away from the conduct of clinical trials, delays in receiving regulatory authorities to initiate clinical trials, and delays in receiving supplies to conduct clinical trials and preclinical studies. For example, there has been an increase in Omicron infections which has impacted patient recruitment at certain of our clinical trial sites and could result in increased costs and delays. In addition, as a result of ongoing COVID-19 research and the current global supply chain issues, there is currently limited availability for certain resources required to conduct some of our preclinical studies and clinical trials, which may result in longer lead times, increased costs, and delays in completing preclinical studies and clinical trials. As a result, research and development expenses and general and administrative expenses may vary significantly if there is an increased impact from COVID-19 on the costs and timing associated with the conduct of the clinical trial and other related business activities.

We are carefully monitoring the pandemic and the potential length and depth of the resulting economic impact on our financial condition, including our cash flows and results of operations. We intend to continue to execute on our strategic plans and operational initiatives during the COVID-19 pandemic. However, the extent to which the COVID-19 pandemic impacts our business will depend on future developments, which are highly uncertain and cannot be predicted, such as the spread or emergence of new variants, the duration and severity of surges in outbreaks, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions, the effectiveness of actions taken in the United States and other countries to contain and treat the disease and to address its impact, including on financial markets or otherwise and other factors identified in Part II, Item 1A “Risk Factors” in this Form 10-K, the related financial impact cannot be reasonably estimated at this time, although the impacts are expected to continue and may significantly affect our business. Accordingly, management is carefully monitoring the impact of COVID-19 pandemic on its business. As of December 31, 2021, we were not aware of any contingencies and no estimates were recorded on our financial statements.

Components of Results of Operations

Revenue

We have not generated any revenue from product sales or otherwise and do not expect to generate any revenue for the foreseeable future.

Operating Expenses

We classify operating expenses into two main categories: (i) research and development expenses and (ii) general and administrative expenses.

Research and Development Expenses

Our research and development expenses consist primarily of external and internal expenses incurred in connection with our research activities and development programs.

107

Table of Contents

These expenses include, but are not limited to:

External expenses, consisting of:

Internal expenses, consisting of:

To date, the vast majority of these expenses have been incurred to advance our most advanced product candidate, AMT-101. We expect that significant additional spending will be required to progress AMT-101 through the remainder of the clinical development phases. These expenses will primarily consist of expenses for the administration of clinical studies as well as manufacturing costs for clinical material supply.

In addition, we have incurred minimal expenses in connection with our second product candidate, AMT-126, including expenses for internal animal studies and preclinical studies performed at contract research organizations. We expect that significant additional spending will be required as we progress AMT-126 through clinical trials. We have also incurred minimal expenses to expand our development pipeline and for general discovery research. We expect spending for these early-stage research and development activities to increase for the foreseeable future. We deploy our personnel, equipment, and facility resources across all our research and development activities.

Research and development expenses are recognized as they are incurred. If deposits are required by external vendors, the non-current portion of the deposit is included as a prepaid expense until the related services are provided.

At this time, we cannot reasonably estimate or know the nature, timing, and estimated costs of the efforts that will be necessary to complete the development of, and obtain regulatory approval for, any of our product candidates. We expect our research and development expenses to increase significantly in the foreseeable future as we continue to invest in research and development activities related to developing our product candidates, as our product candidates advance into later stages of development, as we begin to conduct larger clinical trials, as we seek regulatory approvals for any product candidates that successfully complete clinical trials, and incur expenses associated with hiring additional personnel to support our research and development efforts. The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming, the successful development of our product candidates is highly uncertain, and we may never succeed in achieving regulatory approval for any of our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel-related costs (including salaries, bonuses, benefits, and stock-based compensation expense) for personnel in executive, finance, accounting, corporate development, and other administrative functions. General and administrative expenses also include legal fees, professional fees paid for accounting, auditing, consulting, tax, and investor relations services, insurance costs, and facility costs not otherwise included in research and development expenses, and public company expenses such as costs associated with compliance with the rules and regulations of the SEC and those of the Nasdaq Stock Market.

108

Table of Contents

We expect that our general and administrative expenses will continue to increase significantly in the foreseeable future as additional administrative personnel and services are required to manage these functions of a public company and as our pipeline of product candidates expands.

Interest Income, Net and Other Expense, Net

Interest income, net and other expense, net primarily consists of interest income earned on our cash, cash equivalents, and investments, realized gain and loss on investments, interest expense from capital lease obligations, and net losses on foreign currency transactions related to third-party contracts with foreign-based vendors.

Results of Operations

Comparisons of the Years Ended December 31, 2021 and 2020

Research and Development Expenses

Research and development expenses were $71.4 million for the year ended December 31, 2021, compared to $53.9 million for the year ended December 31, 2020. The overall increase in research and development expenses was primarily related to higher expenses associated with increased headcount, facilities related expenses and clinical trials. In particular, clinical trials expenses increased in fiscal 2021 compared to fiscal 2020 primarily due to progressing our most advanced product candidate, AMT-101, through the completion of Phase 1 studies, initiating AMT-101 Phase 2 studies, and progressing AMT-126 through the initiation of AMT-126 Phase 1 studies. These increases were partially offset by decreases in expenses related to preclinical studies, contract manufacturing and materials expenses. The following table sets forth the primary external and internal research and development expenses for the periods presented below (in thousands).
