For accounting purposes, Chardan Healthcare Acquisition 2 Corp. was deemed to be the acquired entity. Unless the context indicates otherwise, references in this section to the “Company,” “Renovacor,” “we,” “us,” “our” and similar terms refer to Renovacor, Inc. (f/k/a Chardan Healthcare Acquisition 2 Corp.) and our consolidated subsidiaries. References to “Chardan” refer to our predecessor company prior to the consummation of the Business Combination. References to “Old Renovacor” refer to Renovacor, Inc. prior to the consummation of the Business Combination and to Renovacor Holdings, Inc. (f/k/a Renovacor, Inc.), now the wholly owned subsidiary of Renovacor, upon the consummation of the Business Combination.

Overview

We are a biotechnology company focused on delivering innovative precision therapies to improve the lives of patients and families battling genetically-driven cardiovascular and mechanistically-related diseases. Our initial focus is on the treatment of BCL2-associated athanogene 3 (BAG3) mutation-associated dilated cardiomyopathy ("DCM") ("BAG3 DCM"). BAG3 DCM is a heritable rare disease that leads to early onset, rapidly progressing heart failure and significant mortality and morbidity. Our lead product candidate, REN-001, is a recombinant adeno-associated virus ("AAV") 9-based gene therapy designed to deliver a fully functional BAG3 gene to augment BAG3 protein levels in cardiomyocytes and slow or halt progression of BAG3 DCM. BAG3 is a multifunctional, 575-amino acid protein that plays vital roles in ensuring cardiomyocyte function and homeostasis by: i) regulating cardiomyocyte contraction by interacting with the β1-adrenergic receptor and the L-type Ca2+ channel; ii) maintaining structural integrity of the sarcomere; iii) regulating protein quality control; and iv) inhibiting apoptosis by interacting with Bcl-2. Reductions in the level of BAG3 have been associated with the onset of severe cardiac dysfunction and heart failure in a variety of preclinical and clinical settings.

We believe that development of a BAG3 gene replacement therapy for DCM patients who carry BAG3 gene mutations has the potential to prevent progression of DCM and associated heart failure. We believe diseases caused by monogenic defects are especially tractable targets for gene therapies. Recently approved therapies have successfully utilized AAV as a vehicle to deliver genes to patients suffering from monogenic diseases and there are many additional ongoing clinical development programs utilizing AAV-based gene therapies to address these diseases.

We believe we are the first company to apply AAV technology to patients with DCM specifically due to mutations in the BAG3 gene. REN-001 utilizes an AAV9 vector intended to deliver a healthy version of the BAG3 gene to produce functional BAG3 protein in patients with genetic mutations that cause insufficient levels of functional BAG3 protein. This approach has shown promise in multiple preclinical models, demonstrating production of functional BAG3 protein and improvement in cardiac function.

We anticipate submitting an Investigational New Drug ("IND") application in connection with our lead product candidate, REN-001, in the second half of 2022, and plan to initiate a phase I/II clinical trial of REN-001 in patients with BAG3 DCM if our IND application is accepted by the U.S. Food and Drug Administration (“FDA”).

Our Strategy

We intend to build upon our expertise in BAG3-mediated disease to develop a pipeline of BAG3-based therapies for diseases in areas of high unmet medical need associated with mutations in the BAG3 gene. Key elements of our strategy include:

Research and Development

Our Pipeline

In addition to our lead product candidate, REN-001, we are currently developing a pipeline of innovative and proprietary BAG3-associated gene therapies for diseases with high unmet medical need associated with mutations in the BAG3 gene and mechanistically linked to BAG3's expression and function.

Our current pipeline is represented in the diagram below.

* The diagram above is representative of the current stage of our development and does not reflect our expectations of the clinical trials needed or an agreed upon pathway with the FDA for commercialization of our product candidates. We acknowledge that the required clinical studies and pathway to commercialization must be agreed upon with the FDA.

REN-001: Our lead product candidate

Our lead product candidate, REN-001, is an AAV9 vector-based gene therapy designed to treat BAG-3 associated DCM through delivery of a human BAG3 gene to express a fully functional human BAG3 protein in transduced cells. We are currently exploring the delivery of REN-001 through RCSI and anticipate filing an IND for REN-001 in the second half of 2022.

Additional product candidates

Our preclinical strategy includes plans to advance earlier stage research programs where we believe our BAG3 gene therapy technology has the potential to provide meaningful clinical benefit for diseases in areas of high unmet medical need. These research and discovery programs include BAG3-mediated diseases associated with the cardiovascular system and the central nervous system.

Targeting High Unmet Need Cardiovascular Disease

Cardiovascular disease is the leading cause of death worldwide according to the Centers for Disease Control and Prevention. Heart Failure ("HF"), a clinical condition in which the output of blood from the heart is insufficient to meet the metabolic demands of the body, is a major contributor to cardiovascular morbidity and mortality. HF affects over 15 million people in the United States and in the European Economic Area (the "EEA"). We believe the number of people with heart failure in the United States and EEA is expected to increase in the next decade due to an aging population and increasing prevalence of risk factors for cardiovascular disease, including obesity and diabetes. Common symptoms and signs of heart failure include shortness of breath, fatigue and swelling of the ankles, feet, legs, abdomen and veins in the neck. When HF symptoms become severe, the patient is referred to as having acute decompensated HF ("ADHF"), a life-threatening event. Currently, among the approximately 6 million HF patients in the US, there are approximately one million primary HF-related hospitalizations in the United States each year. The large majority of these hospitalizations are for ADHF. Despite recent advances in HF therapy, approximately half of patients hospitalized with ADHF are readmitted within 6 months, an example of the severe unmet need for this condition.

Clinicians generally segment the HF patient population based on the contractility of the major pumping chamber of the heart, the left ventricle ("LV"). The most commonly used measure of LV contractility is ejection fraction ("EF"). HF patients with normal LV contractility (≥50%) are referred to as having HF with preserved LVEF ("HFpEF"), while those with an LVEF < 40% are referred to as having HF with reduced LVEF ("HfrEF"). A relatively small number of HF patients have an LVEF 40-49% and are described as having HF with midrange EF ("HfmrEF"). Scientific society treatment guidelines have established different treatment algorithms for the different HF patient segments.

DCM represents a segment of the HFrEF population with primary disease of the myocardium (heart muscle), and the primary cause of cardiac dysfunction in approximately 20-25% of HFrEF patients.

A familial association of DCM can be identified in 20-50% of DCM patients, with up to 40% of familial patients having an identifiable genetic cause. Mutations in the BAG3 gene are among the more common pathogenic genetic variants observed in familial DCM and these variants are highly penetrant, with approximately 80% of individuals with disease-causing genetic variants in the BAG3 gene developing DCM at > 40 years of age. We estimate that the prevalence of BAG3-associated DCM in the United States to be as many as 30,000 individuals, representing an orphan disease population. Currently, DCM patients with a BAG3 mutation are treated with the standard of care for heart failure, which include angiotensin converting enzyme inhibitors, angiotensin receptor blockers, neprilysin inhibitors, beta-adrenergic receptor antagonists, or beta-blockers, aldosterone antagonists and/or diuretics, along with certain lifestyle changes, and do not address the underlying cause of disease. Patients who meet specific parameters may also undergo placement of an implantable cardioverter defibrillator, a cardiac resynchronization device or a combination of the two. There is no current therapy directly targeting the underlying mechanism of BAG3 associated DCM, and patients diagnosed with BAG3 associated DCM appear to progress to end-stage heart failure and death more rapidly than patients with DCM not associated with BAG3 variants. For example, approximately 19% of patients with BAG3 DCM require mechanical cardiac support, heart transplant, or have HF-related death at 12 months after diagnosis, nearly twice the rate of similarly staged non-BAG3 DCM patients.

REN-001 (AAV9-BAG3): Our Lead Product Candidate

Overview

Our lead product candidate, REN-001, is an AAV9 vector-based gene therapy designed to treat BAG-3 associated DCM through delivery of a human BAG3 gene to express a fully functional human BAG3 protein in transduced cells. After transducing the cardiomyocyte, the vector translocates into the nucleus, where the capsid proteins dissociate, allowing the cell’s native expression machinery to initiate transcription of the BAG3 gene. Unlike wild-type AAVs, REN-001 lacks an S1 domain, which significantly limits the potential for the vector genome to integrate into the host chromosome. Instead, the gene has the potential to remain in the nucleus as episomal DNA.

Third-party studies have demonstrated that recombinant AAV-delivered episomal DNA persists in the nucleus of transfected non-proliferating cells for up to several years. This suggests that a single dose of REN-001 could provide prolonged BAG3 gene replacement in haploinsufficient cells transduced by the vector. Following transcription and translation of the BAG3 gene, the function of the BAG3 protein is expected to be restored, and disease progression has the potential to be halted or significantly slowed.

We are currently exploring the delivery of REN-001 through RCSI and anticipate submitting an IND for REN-001 in the second half of 2022.

The AAV9-BAG3 gene vector

The AAV9-BAG3 gene vector utilized in REN-001 is comprised of the four exons of the human BAG3 gene, two AAV2 inverted terminal repeat ("ITR"), segments, a CMV promoter, and the three AAV9 cap proteins VP1, VP2, and VP3 (Figure 1).

Figure 1: The entire AAV9-BAG3 vector genome is approximately 6,048 bases in length. Each ITR — derived from the AAV2 genome — is 143 bases, and the CMV and BAG3genes are 584 and 1,728 bases in length, respectively. The capsid is comprised of VP1, VP2, and VP3 cap proteins from the AAV9 genome.

The AAV9-BAG3 gene vector utilized in REN-001 is designed to be administered to patients through RCSI. AAV9-BAG3 is not cleared after a first pass via the mononuclear phagocyte system but rather circulates for up to multiple days, albeit at a much lower concentration relative to the concentration in the coronary circulation at the time of dosing. After transducing the cardiomyocyte, AAV9-BAG3 will translocate into the nucleus, where the capsid proteins will dissociate, allowing the cell’s native expression machinery to initiate transcription of the BAG3 gene.

Following transcription and translation of the BAG3 gene, we believe the function of the BAG3 protein will be restored, (including the maintenance of the sarcomeres, normalization of protein quality control, inhibition of programmed cell death, and improved responsiveness to adrenergic signals) and disease progression is expected to be halted or significantly slowed.

Safety considerations of AAV9-BAG3 administration

Prior gene therapy programs in and outside the cardiac space have raised safety concerns. Some BAG3-haploinsufficient patients will have already developed serum immunoglobulin G ("IgG") and neutralizing factors to the VP1, VP2, and/or VP3 cap proteins of the AAV9 serotype and will not be eligible for an AAV-related gene therapy.

It is of critical importance that safety be the primary concern of any study of gene therapy. Because pre-existing antibodies remain a significant problem in the use of gene therapy, we will screen and exclude BAG3-haploinsufficient patients from our clinical development studies and post-approval use in whom the titer of IgG antibodies exceeds an acceptable level. Furthermore, during the course of our preclinical studies, we will work with national experts to design standard protocols for treating patients who develop signs of inflammation after dosing.

Gene therapy also carries a risk of transduction into off-target tissues. One of the key benefits of adeno- associated viral vectors is their tropism for specific tissues. AAV9 was selected for REN-001 because of its tropism for cardiac tissue. Studies in mice and a pilot study in pigs demonstrate that our AAV9-BAG3 results in robust expression in the heart with little expression in the kidney, lung or liver.

A safety concern with all AAV-based gene therapy is that AAV administration could lead to the integration of the gene into the target cell’s genome. AAV vectors lacking an S1 domain transduce their genes into episomal DNA, rather than integrating into the chromosome. Because episomal DNA is not replicated during mitosis, the daughter cells will not contain the transduced genetic sequences. This is important in the context of BAG3 gene therapy. BAG3 is not oncogenic, as there is no evidence to date that shows it can cause a non-malignant cell to transform into a malignant cell. However, BAG3 has been shown to enhance migration, adhesion and insensitivity to chemotherapy when over-expressed in cancer cells. Therefore, there is a theoretical risk that a tumor will have increased metastasis if it over-expresses BAG3. We believe REN-001 mitigates this possibility by utilizing an AAV vector that lacks the S1 domain.

5

Across all gene therapy programs, regardless of the specificity of the vector and the promoter selected, there is at least a 0.01%-1% risk of integration as a percentage of vectors that successfully transduce and translocate into the nucleus. Due to random integration, it is unlikely that the gene will transcribe. If, however, the placement of the BAG3 gene is next to a universal enhancer, there is a chance of expression. It is also a possibility that the BAG3 gene could disrupt an otherwise healthy gene, potentially resulting in a loss-of-function mutation or other phenotypic abnormalities. Because this integration is restricted to each individual transfected cell, there is no test to identify that the event has occurred, and all patients who undergo gene therapy will require careful long-term follow-up.

Preclinical research and development for REN-001

We are currently conducting preclinical studies exploring the ability of a BAG3 gene therapy to treat patients suffering from DCM caused by BAG3 haploinsufficiency. In conducting preclinical research in this field to generate data validating this novel therapeutic approach, animal studies have been completed in several heart failure disease models, including studies involving mice subjected to trans-aortic constriction, mice suffering from left ventricular dysfunction following a myocardial infarction ("MI"), mice with left ventricular dysfunction post-ischemia and reperfusion, and large animal studies in pigs suffering from left ventricular dysfunction following an MI.

Figure 2: BAG3 protein levels in cardiac tissue from failing hearts is decreased to 50% of normal levels.

BAG3 protein levels in all heart failure models we studied, as well as other research groups, show that in failing hearts there is a decrease in BAG3 protein by approximately 50% (Figure 2). Administration of REN-001 to post-MI mice led to an increase in BAG3 cardiac protein levels bringing them up to ~70% of levels seen in non-failing hearts. This increase in BAG3 protein levels resulted in a significant functional increase as measured by ejection fraction.

Additionally, we have studied the efficacy of AAV9-BAG3 treatment in a BAG3-haploinsufficient mouse model of DCM, as well as a pilot study in a pig MI model. To further characterize BAG3 biology, we have conducted numerous studies evaluating the mechanism of action of the BAG3 protein in the cardiomyocyte.

Completed preclinical studies of REN-001

REN-001 has been studied in multiple preclinical animal models of heart failure. These studies have demonstrated the ability of REN-001 to induce increased expression of BAG3 protein and to improve cardiac function.

BAG3 haploinsufficient mouse model

To test the impact of AAV9-BAG3 on left ventricle, ("LV") function, mice with haploinsufficiency of BAG3 were injected with either AAV9-BAG3 or with AAV9-GFP (control). The mice were then observed for six weeks, after which biomarkers and proteins that may impact the pathophysiology of BAG3 depletion were measured. AAV9-BAG3 was able to restore normal LV function in BAG3 haploinsufficient mice, as illustrated below (Figure 3).

Figure 3: Ejection fraction ("EF") measurements of wild-type BAG3 and GFP transduction into haploinsufficient and control mice (* p=0.04, 0.01, and 0.003 respectively at 2, 4 and 6 weeks for +/-GFP vs. +/-WtBAG3).

Post-myocardial infarction (MI) mouse model

To test the effects of retro-orbital injection of AAV9-BAG3, eight-week old male c57BL/6 mice were randomly assigned to undergo either an induction of an MI by left coronary artery ligation that led to a significant reduction in LV function or a sham procedure. Mice in each group were randomized to receive either gene therapy with BAG3 or with GFP (MI-AAV9-BAG3, n=13, MI-AAV9-GFP, n=12, Sham-AAV9-BAG3, n=12, Sham- AAV9-GFP, n=14) 1 week after surgery. Left ventricular function across study groups was assessed using echocardiography. As illustrated below, AAV9-BAG3 significantly improved LV performance when compared with the AAV9-GFP control. Furthermore, AAV9-BAG3 had no effect on LV performance in mice in the sham arm, demonstrating that BAG3 levels are precisely regulated under normal conditions (Figure 4).

(Right) LVEF measurements for individual mice at the time of sacrifice (* p <0.0001, † p < 0.0001).

7

Trans-aortic constriction (TAC) mouse model

To test the effects of AAV9-BAG3 on LV function in mice with TAC, a ligature was tied over the ascending aorta of mice, with surgical consistency being assessed by constricting the aorta over a needle and then evaluating the subsequent obstruction to forward flow setting limits for the variation in trans-constriction pressures. Trans-aortic pressures were measured in all animals to ensure that there was little variation from animal to animal. The experimental paradigm included wild-type mice receiving AAV9-BAG3 or AAV9-GFP, and post-TAC mice receiving AAV9-BAG3 or AAV9-GFP. Dosing occurred at week 9 with a dose of 1x1012 vectors. Functional parameters were measured bi-weekly via echocardiography. As illustrated below, this TAC procedure resulted in lower relative levels of BAG3 expression compared to controls, and treatment with AAV9-BAG3 at 9 weeks following TAC resulted in significant improvements in functional measures of the LV (Figure 5).

Figure 5: (Left) BAG3 protein levels, normalized to Glyceraldehyde 3-phosphate dehydrogenase 7 weeks after a sham procedure or TAC (prior to AAV9 dosing). (Right) Fractional shortening percentage measurements over the course of sham or TAC surgical procedure and AAV9-BAG3 or AAV9-GFP administration. Note: y-axis does not extend to 0% (p=0.001).

Post-myocardial infarction (MI) pig model

We evaluated the MI pig model in a pilot study to evaluate the reproducibility of the infarcted phenotype in this model, the method of retrograde delivery of REN-001, and the transduction efficiency and efficacy of REN-001 in a large animal model. In order to be included in the study, pigs were required to be free of AAV neutralizing antibodies throughout the study and demonstrate a reduced LVEF post-infarction. Six infarcted Yucatan pigs were treated with a single dose of REN-001, and four were treated with vehicle, through RCSI at two weeks post-MI. The pigs were then followed for an additional six weeks before being sacrificed and assessed for BAG3 protein levels in cardiac tissue. Cardiac function was also assessed pre-MI, and at two and six weeks post-MI.

At the time of injection (two weeks post-MI), four of the six animals in the treatment group and four of the four animals in the vehicle control group had developed neutralizing antibodies. Additionally, of the two animals in the treatment group that did not develop neutralizing antibodies, one did not have a sufficient decline in LVEF post-MI to meet the study inclusion criteria. Thus, only one of the six animals in the treatment group met the study inclusion criteria. For this animal, REN-001 treatment resulted in diffuse BAG3 transgene expression in the cardiac tissue and improvement in LVEF. In the vehicle control group, one pig did not have a sufficient decline in EF to meet the study inclusion criteria, two pigs had an LVEF that continued to decline and one pig had improved LVEF at the conclusion of the study. Due to the challenges with neutralizing antibodies and the variability of the infarct procedure in these animals, we concluded that the MI pig model is not a reliable, reproducible animal model for further assessment of transduction efficiency and efficacy studies. The MI pig model is no longer being used for REN-001 efficacy studies. All further large animal studies are being conducted in normal Yucatan pigs to optimize intracoronary dosing and assess biodistribution. These conclusions do not impact the ongoing preclinical development plan for REN-001 which includes expression and efficacy studies in the BAG3 haploinsufficient mouse model coupled with a GLP toxicology and biodistribution study in normal Yucatan pigs as presented to the FDA in the Pre-IND briefing package.

AAV9-GFP delivery and transduction efficiency in normal Yucatan pigs

To compare antegrade vs. retrograde delivery of AAV9-GFP and to assess AAV transduction efficacy in cardiac tissue, eight non-infarcted Yucatan pigs were given an infusion of a single low dose AAV9-GFP (1x1013 vg, n=4), high dose AAV9-GFP (5x1013 vg, n=2) or vehicle (n=2). Within each treatment group, half of the pigs received antegrade infusion of AAV9-GFP while the other half received RCSI of AAV9-GFP. All of the pigs were assessed for AAV transduction in cardiac tissue via GFP reporter gene four weeks post-infusion.

Retrograde delivery of AAV9-GFP was more effective in transducing cardiac tissue than antegrade delivery. The 5x1013 vg dose of AAV9-GFP through RCSI resulted in clear expression of AAV9-GFP in cardiac tissue four weeks post treatment. Antegrade delivery of AAV9-GFP at the 5x1013 vg dose did not yield a similar level of expression. No expression was observed in animals treated with 1x1013 vg dose of AAV9-GFP through either delivery method four weeks post treatment.

REN-001 delivery via RCSI and transduction efficiency in normal Yucatan pigs

To evaluate the transduction efficiency of REN-001 administered via RCSI, a total of seven non-infarcted Yucatan pigs were administered REN-001 at multiple doses (n=4 for low-dose; n=2 for medium dose; n=1 for high dose). We quantified transduction as viral genomes per cardiomyocyte (CM), assuming 8 nuclei in each CM, and 18 tissue sections were analyzed per heart. As illustrated below, delivery of REN-001 via RCSI resulted in successful cardiac transduction above a key vector copy number ("VCN") threshold at doses less than 1x1013 vector genomes (vg) per kilogram (Figure 6).

Figure 6: Viral genomes per cardiomyocyte are shown as the mean (+SEM) of 18 tissue sections taken per heart (excluding values >3 standard deviations from the mean) and assume 8 nuclei in each cardiomyocyte (Velayuthan et al., J Mol Cell Cardiology, 2020); number of animals/group: low dose (n=4), medium dose (n=2) and high dose (n=1). All doses were <1x1013 vg/kg.

No safety issues were detected in this preclinical study. Results of this preclinical pilot study informed the design of our ongoing GLP toxicology and biodistribution IND-enabling study.

Ongoing preclinical studies of REN-001

We have several preclinical studies of REN-001 currently in progress to further evaluate AAV9 transduction efficiency, safety, and efficacy in mouse and pig models. These studies include a dose-ranging efficacy study, a durability of effect study, and a natural history study (including survival analysis), each in BAG3 haploinsufficient mice, which continue to progress at the Feldman laboratory at Temple pursuant to the Temple SRA, as defined below. Preliminary data from our ongoing natural history study has demonstrated an impaired survival phenotype, alongside left ventricular dilation and cardiac function decline, findings that are consistent with several hallmark characteristics of DCM seen clinically in patients. These new data have been leveraged to optimize the design of our ongoing dose-ranging study.

Additionally, our good laboratory practice (“GLP”) toxicology and biodistribution study in normal Yucatan pigs using the RCSI route of administration is ongoing and has completed dosing.

We anticipate the availability of key data from our ongoing preclinical studies to support an IND submission in the second half of 2022.

Clinical Development Plan for REN-001

We completed a Type B Pre-IND meeting with the FDA on June 16, 2020 to obtain FDA feedback on REN-001. We anticipate submitting an IND for REN-001 in the second half of 2022, and plan to initiate a phase I/II clinical trial of REN-001 in patients with BAG3-associated DCM if our IND submission is accepted by the FDA. We expect the phase I/II clinical trial will be conducted in two sequential parts consisting of dose escalation and dose expansion components. The dose escalation part will enroll cohorts of three to six subjects to identify a preferred dose and be followed by a dose expansion cohort to further explore the safety, tolerability and preliminary evidence of efficacy at the preferred dose. This will be an open label study with the goal of evaluating the safety and efficacy of REN-001. Safety and tolerability will be evaluated based on assessment of frequency and severity measures of adverse events and series of adverse events. Efficacy will be evaluated based on measures of cardiac structure and function, circulating biomarkers, and patient functional capacity and quality of life.

We will consult with the FDA following completion of the phase I/II clinical trial to determine the need for, and optimal design of, future clinical trials.

Other Target Indications

Our preclinical strategy includes plans to advance earlier stage research programs where we believe our BAG3 gene therapy technology has the potential to provide meaningful clinical benefit for diseases in areas of high unmet medical need. These research and discovery programs include BAG3-mediated diseases associated with the cardiovascular system and the central nervous system.

Temple retains the right to practice and use the Temple Patent Rights for noncommercial educational and research purposes, and also to license other nonprofit academic and research institutions to practice the Temple Patent Rights solely for noncommercial educational and research purposes.

In consideration for the rights granted to us under the Temple License Agreement, we issued an aggregate of 107,009 shares of our common stock to Temple. We also reimbursed Temple for the patent prosecution and maintenance costs incurred by Temple for the licensed patent rights prior to us entering into the license agreement, and we are responsible for all ongoing costs relating to the prosecution and maintenance of the licensed Temple Patent Rights going forward. We also agreed to pay Temple a minimum annual administrative fee of $20,000 per year beginning with the effective date of the License Agreement and continuing each annual anniversary thereafter.

Under the Temple License Agreement, we are also required to pay up to an aggregate of approximately $1.25 million upon the achievement of certain developmental, regulatory and commercial milestones for the first licensed product that achieves said milestones regardless of the number of licensed products that achieve them. In addition, we are required to pay Temple a low single-digit royalty on net sales of any product utilizing the Temple Patent Rights, up to 50% of which may be reduced by payments we make to third parties for freedom to operate.

In addition, we must also pay a percentage of all consideration based on a percentage of sublicense consideration we receive, which percentage ranges from the mid-teens to mid-twenties depending on the stage of development at the time of the sublicense agreement. The Temple License Agreement requires that we use commercially reasonable efforts to bring to market at least one licensed product during the term of the Temple License Agreement, effect its commercialization as soon as practicable and keep the licensed product reasonably available to the public.

The Temple License Agreement will remain effective until (i) the expiration date of the last-to-expire patents covered under the Temple License Agreement (currently expected to occur in 2041), (ii) the termination by Temple upon (a) an uncured breach by us, with a 60-day notification period, (b) our filing of a voluntary petition in bankruptcy or related proceeding, provided such petition is not dismissed within 90 days after the filing thereof, (c) a failure by us to meet certain milestones set forth in the Temple License Agreement, or (d) non-payment of undisputed monies due to Temple, with a 30-day notification period. Additionally, we may terminate the entire agreement or with respect to an individual patent or patent application, if desired, subject to a 90-day notification period.

Sponsored Research Agreement with Temple

We are party to a Sponsored Research Agreement with Temple, dated August 12, 2019, as amended August 27, 2019 and August 18, 2021 (the “Temple SRA”). Under the Temple SRA, Temple conducts certain preclinical development and translational research activities with respect to licensed technology and know-how, which, in the aggregate, are intended to support our IND submission for REN-001 and future clinical development. We are responsible for all subsequent clinical development and commercialization activities with respect to the licensed technology and know-how. We are currently obligated to fund a total of up to approximately $5.3 million to Temple under the Temple SRA in connection with certain research and development activities to be performed by Temple through June 30, 2024. See Note 9 of the Notes to Financial Statements included elsewhere in this Annual Report on Form 10-K for additional information.

Manufacturing

Gene therapy manufacturing is a critical factor in the successful development and commercialization of novel gene medicines. We do not currently own or operate, and currently have no plans to establish, any manufacturing facilities for the production of preclinical, clinical, or commercial quantities of REN-001, or any other product candidate. We currently depend on a limited number of third-party contract development and manufacturing organizations ("CDMOs") for all of our requirements of raw materials, drug substance and drug product for our preclinical research and clinical supply of REN-001. We are not currently party to any long-term agreements with our current CDMOs. We intend to rely on CDMOs for clinical and commercial manufacturing of REN-001, as well as the clinical and commercial manufacturing of our other product candidates and any other product candidates that we may identify in the future. Although we rely on CDMOs, we have employees and third-party consultants with extensive manufacturing experience to oversee the relationships with our contract manufacturers.

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. We are currently developing REN-001, our AAV9-based gene therapy designed to treat BAG-3 associated DCM. There are many other companies, both public and private, that are actively engaged in discovery, development, and commercializing products and technologies that may compete with our drug candidate, REN-001, or any other drug candidate we may develop. Our products, if approved, will compete with novel therapies developed by biopharmaceutical companies, academic research institutions, governmental agencies and public and private research institutions, in addition to standard of care treatments. Our competitors compete with us on the level of the technologies employed, or on the level of development of product candidates. In addition, many small biotechnology companies have formed collaborations with large, established companies to obtain support for their research, development and commercialization of products or combine several treatment approaches to develop longer lasting or more efficacious treatments that may potentially directly compete with our current or future product candidates. We anticipate that we will continue to face increasing competition as new therapies and combinations thereof, technologies, and data emerge within the field of gene therapy and, furthermore, within the treatment of heart failure.

Many of our competitors, either alone or with their strategic partners, have substantially greater financial, technical, and human resources than we do and significantly greater experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of treatments, and the commercialization of those treatments. Accordingly, our competitors may be more successful than us in obtaining approval for treatments and achieving widespread market acceptance.

In the field of cardiomyopathy drug development, we are aware of several companies that may compete with us, including, Alnylam Pharmaceuticals, Bayer AG, BioMarin Pharmaceutical, BridgeBio Pharma, Bristol-Myers Squibb Company, Cytokinetics, DiNAQOR AG, Ionis Pharmaceuticals, Sardocor Corp., Skyline Therapeutics, Tenaya Therapeutics and Takeda Pharmaceutical Company Limited. We are also aware of other companies developing gene therapies targeting heart failure, however, to the best of our knowledge, none of these company's' programs are aimed directly at increasing BAG3 expression and we are not aware of any formally disclosed programs actively under development for BAG3 DCM. Nevertheless, these companies may compete with us in recruiting human capital and securing licenses to complementary technologies that may be critical to the success of our business. They also compete with us for potential funding from the biotechnology and pharmaceutical industries. There may be other companies pursuing therapeutic candidates from which we may face current or future competition.

Our commercial potential 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 products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for our products, which could result in our competitors establishing a strong market position before we are able to enter the market or make our development more complicated. The key competitive factors affecting the success of all of our programs are likely to be efficacy, safety, and convenience.

These competitors may also vie for a similar pool of qualified scientific and management talent, sites and patient populations for clinical trials, as well as for technologies complementary to, or necessary for, our products.

Risks related to our competitors and our competitive position are discussed in further detail in the section entitled “Risk Factors” of this Annual Report on Form 10-K.

Intellectual Property

We strive to protect our product candidates and BAG3 technology through a variety of methods, including seeking and maintaining patent rights intended to cover our BAG3 technology, its compositions, the methods of use and processes for their manufacture, and any other inventions that may be commercially important to the development of our business. We may also rely on know-how, continuing technological innovation and in-licensing opportunities to develop and maintain our proprietary position. In addition, we may rely on trade secrets and know-how that may be important to the development of our business.

We are actively building our intellectual property portfolio around our product candidates and discovery programs, primarily based on our licensed intellectual property. As of March 15, 2022, we own or exclusively license a total of 39 pending patent applications of which there are 36 pending applications and one granted U.S. patent, one granted Japanese patent and one granted European patent license from Temple. In September 2021, an opposition was filed against the European patent. We responded in January 2022 rebutting all grounds of the opponent’s opposition. Of the 36 pending in-licensed patent applications, there are four U.S. utility applications, one pending U.S. provisional application and 31 pending ex-U.S. patent applications. In addition, we own one pending U.S. provisional application and jointly own two pending U.S. provisional applications with Temple. Collectively, these patent rights relate to various aspects of our BAG3 product candidates and technology. We expect to file additional patent applications in support of current and future product candidates.

The term of individual patents depends upon the laws of the countries in which they are obtained. In most countries in which we file, the patent term is 20 years from the earliest date of filing of a non-provisional patent application. However, the term of United States patents may be extended for delays incurred due to compliance with the FDA requirements or by delays encountered during prosecution that are caused by the U.S. Patent and Trademark Office ("USPTO"). For example, for drugs that are regulated by the FDA under the Hatch-Waxman Act, it is permitted to extend the term of a patent that covers such drug for up to five years beyond the normal expiration date of the patent. In the future, if and when our product candidates receive FDA approval, we expect to apply for patent term extensions on patents covering those product candidates. We intend to seek patent term extensions to any of our issued patents in any jurisdiction where these are available; however, there is no guarantee that the applicable authorities, including the USPTO and FDA, will agree with our assessment of whether such extensions should be granted, and even if granted, the length of such extensions. The actual protection afforded by a patent varies on a product-by-product basis, from country-to-country, and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory-related extensions, the availability of legal remedies in a particular country and the validity and enforceability of the patent. For this and more comprehensive risks related to our intellectual property, please see “Risk Factors — Risks Related to Our Intellectual Property.”

Patents and pending patent applications

Of the 39 pending patent applications, there are eight families. One application family licensed from Temple relates to the treatment of heart failure in patients with reduced BAG3 expression and reduced EF. The term of any patent that issues from these applications will expire in 2035, excluding any additional term for patent term adjustment or patent term extension, if applicable. Three application families licensed from Temple relate to the use of BAG3 for increasing cardiac contractility in patients with heart failure due to reduced EF, the treatment of ischemia/reperfusion injury, and the treatment of subpopulations of individuals with BAG3 genetic variants that cause worsening outcomes in dilated cardiomyopathy. The term of any patent that issues from applications within these families will expire in 2036, 2037 and 2039 respectively, excluding any additional term for patent term adjustment or patent term extension, if applicable.

Three other application families either co-owned with or licensed from Temple relate to treatment of additional diseases. One application family we own relates to cardiac administration of therapeutics. The term of any patent that issues from applications in these families will expire in 2042, excluding any additional term for patent term adjustment or patent term extension, if applicable.

Trademarks and pending trademark applications

We intend to file applications for trademark registrations in connection with our approved products in jurisdictions relevant to our business plans. We own registered trademarks and trademark applications in the U.S., European Union, U.K, Canada, Japan, China and Israel that are directed to our name and logo covering services provided in connection with gene therapy.

13

Trade secrets

We may rely on trade secret protection for our confidential and proprietary information. We take steps to protect our confidential and proprietary information as trade secrets, including through contractual means with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors. It is our policy to require our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to execute confidentiality agreements under the commencement of employment or consulting relationships with us. These agreements provide that all confidential information concerning our business or financial affairs developed or made known to the individual during the individual’s relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees, the agreements provide that all inventions conceived by the individual, and which are related to its current or planned business or research and development or made during normal working hours, on our premises or using our equipment or proprietary information, are our exclusive property. In many cases our confidentiality and other agreements with consultants, outside scientific collaborators, sponsored researchers and other advisors require them to assign or grant us licenses to inventions they invent as a result of the work or services they render under such agreements or grant us an option to negotiate a license to use such inventions.

Government Regulation

In the United States, drug and biologic products are licensed by FDA for marketing under the Public Health Service Act (the "PHS Act") and regulated under the Federal Food, Drug, and Cosmetic Act (the "FDCA"). Both the FDCA and the PHS Act and their corresponding regulations govern, among other things, the testing, manufacturing, safety, purity, potency, efficacy, labeling, packaging, storage, record keeping, distribution, marketing, sales, import, export, reporting, advertising and other promotional practices involving drug and biological products. FDA clearance must be obtained before clinical testing of drug and biologic products. FDA licensure also must be obtained before marketing of drug and biological products. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources.

U.S. Development Process

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

14

Before testing any drug or biological product candidate in humans, the product candidate enters the preclinical testing stage. Nonclinical tests include laboratory evaluations of product chemistry, pharmacology, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the product candidate. The conduct of the nonclinical tests must comply with federal regulations and requirements including GLPs.

The clinical study sponsor must submit the results of the nonclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. Some nonclinical testing typically continues after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA requests certain changes to a protocol before the trial can begin, or the FDA places the clinical trial on a clinical hold within that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may also impose clinical holds on a drug or biological product candidate at any time before or during clinical trials due to safety concerns or non-compliance. If the FDA imposes a clinical hold, trials may not recommence without FDA authorization and then only under terms authorized by the FDA.

Clinical trials involving some products for certain diseases, including some rare diseases may begin with testing in patients with the disease. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety, including stopping rules that assure a clinical trial will be stopped if certain adverse events should occur. Clinical trials must be conducted and monitored in accordance with the FDA’s regulations comprising the GCP requirements, including the requirement that all research subjects or their legal representatives provide informed consent. Further, each clinical trial must be reviewed and approved by an independent IRB, at or servicing each institution at which the clinical trial will be conducted. An IRB is charged with protecting the welfare and rights of study participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the form and content of the informed consent that must be signed by each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. Additionally, some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety monitoring board or committee.

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

Post-approval clinical trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These clinical trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow-up.

During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA. Written IND safety reports must be promptly submitted to the FDA and the investigators for serious and unexpected adverse events, any findings from other studies, tests in laboratory animals or in vitro testing that suggest a significant risk for human subjects, or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the physical characteristics of the drug or biological product as well as finalize a process for manufacturing the product in commercial quantities in accordance with GMP requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHS Act emphasizes the importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of the final

15

biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug or biological product candidate does not undergo unacceptable deterioration over its shelf life.

Information about certain clinical trials must be submitted within specific timeframes to the NIH for public dissemination on its clinicaltrials.gov website. Sponsors or distributors of investigational products for the diagnosis, monitoring, or treatment of one or more serious diseases or conditions must also have a publicly available policy on evaluating and responding to requests for expanded access requests.

U.S. Review and Approval Processes

After the completion of clinical trials of a drug or biological product, FDA approval of an NDA or BLA must be obtained before commercial marketing of the product. The NDA or BLA must include results of product development, laboratory and animal studies, human studies, information on the manufacture and composition of the product, proposed labeling and other relevant information. The testing and approval processes require substantial time and effort and there can be no assurance that the FDA will accept the NDA or BLA for filing and, even if filed, that any approval will be granted on a timely basis, if at all.

Within 60 days following submission of the application, the FDA reviews an NDA or BLA submitted to determine if it is substantially complete before the agency accepts it for filing. The FDA may refuse to file any NDA or BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. Once the submission is accepted for filing, the FDA begins an in-depth substantive review of the NDA or BLA. The FDA reviews the NDA or BLA to determine, among other things, whether the proposed product is safe, potent, and effective for its intended use, has an acceptable purity profile, and is being manufactured in accordance with GMPs to assure and preserve the product’s identity, safety, strength, quality, potency and purity. The FDA may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. During the drug or biological product approval process, the FDA also will determine whether a REMS is necessary to assure the safe use of the drug or biological product. If the FDA concludes a REMS is needed, the sponsor of the NDA or BLA must submit a proposed REMS; the FDA will not approve the NDA or BLA without a REMS, if required.

Before approving an NDA or BLA, the FDA may inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with GMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA or BLA, the FDA will typically inspect one or more clinical trial sites to assure that the clinical trials were conducted in compliance with IND study requirements and GCP requirements. To assure GMP and GCP compliance, an applicant must incur significant expenditure of time, money and effort in the areas of training, record keeping, production, and quality control.

Notwithstanding the submission of relevant data and information, the FDA may ultimately decide that the NDA or BLA does not satisfy its regulatory criteria for approval and deny approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than the sponsor interprets the same data. If the agency decides not to approve the NDA or BLA in its present form, the FDA will issue a complete response letter that usually describes all of the specific deficiencies in the NDA or BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical trials. Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the NDA or BLA, addressing all of the deficiencies identified in the letter, or withdraw the application.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a risk management plan, or otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to as Phase 4 clinical trials, designed to further assess a drug or biological product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of approved products that have been commercialized. As a condition for approval, the FDA may also require additional nonclinical testing as a Phase 4 commitment.

One of the performance goals agreed to by the FDA under the PDUFA is to review standard NDAs or BLAs in ten months from filing and priority NDAs or BLAs in six months from filing, whereupon a review decision is to be made. The FDA does not always meet its PDUFA goal dates for standard and priority NDAs or BLAs and its review goals are subject to change from time to time. The review process and the PDUFA goal date may be extended by three months if the FDA requests or the NDA or BLA sponsor otherwise

16

provides additional information or clarification regarding information already provided in the submission within the last three months before the PDUFA goal date.

Post-Approval Requirements

Maintaining substantial compliance with applicable federal, state, and local statutes and regulations requires the expenditure of substantial time and financial resources. Rigorous and extensive FDA regulation of drug and biological products continues after approval, particularly with respect to GMP. We will rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of any products that we may commercialize. Manufacturers of our products are required to comply with applicable requirements in the GMP regulations, including quality control and quality assurance and maintenance of records and documentation.

Following approval, the manufacturing facilities are subject to biennial inspections by the FDA, and such inspections may result in an issuance of FDA Form 483 deficiency observations, untitled letter, or a warning letter, which can lead to plant shutdown and other more serious penalties and fines. Prior to the institution of any manufacturing changes, a determination needs to be made whether FDA approval is required in advance. If not done in accordance with FDA expectations, the FDA may restrict supply and may take further action. Annual product reports are required to be submitted annually. Other post-approval requirements applicable to drug and biological products include reporting of GMP deviations that may affect the identity, potency, purity and overall safety of a distributed product, record-keeping requirements, reporting of adverse events, reporting updated safety and efficacy information, and complying with electronic record and signature requirements.

We also must comply with the FDA’s advertising and promotion requirements, such as those related to direct-to-consumer advertising, the prohibition on promoting products for uses or in patient populations that are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the internet. Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions.

Drug and biological product manufacturers and other entities involved in the manufacture and distribution of approved drug and biological products 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 GMPs and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the areas of production and quality control to maintain GMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved NDA or BLA, including withdrawal of the product from the market. In addition, changes to the manufacturing process or facility generally require prior FDA approval before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant Orphan Drug Designation ("ODD") to a drug or biological product intended to treat a rare disease or condition, which is generally 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 and for which there is no reasonable expectation that the cost of developing and making a drug or biological product available in the United States for this type of disease or condition will be recovered from sales of the product. ODD must be requested before submitting a BLA. After the FDA grants ODD, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. ODD does not convey any advantage in or shorten the duration of the regulatory review and approval process.

If a product that has ODD receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same biological product for the same indication for seven years, except in limited circumstances, such as not being able to supply the product for patients or showing clinical superiority to the product with orphan exclusivity.

Competitors, however, may receive approval of different products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan product exclusivity also could block the approval of one of our products for seven years if a competitor obtains approval of the same drug or biological product as defined by the FDA or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease. If a drug or biological product designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan product exclusivity.

17

Expedited Review and Approval Programs

The FDA has various programs, including fast track designation, priority review, accelerated approval, and breakthrough therapy designation, that are intended to expedite or simplify the process for the development and FDA review of drug and biological products that are intended for the treatment of serious or life-threatening diseases or conditions and demonstrate the potential to address unmet medical needs. The purpose of these programs is to provide important new drug and biological products to patients earlier than under standard FDA review procedures. To be eligible for a fast track designation, the FDA must determine, based on the request of a sponsor, that a drug or biological product is intended to treat a serious or life-threatening disease or condition and demonstrates the potential to address an unmet medical need. The FDA will determine that a product will fill an unmet medical need if it will provide a therapy where none exists or provide a therapy that may be potentially superior to existing therapy based on efficacy or safety factors. In addition to other benefits, such as the ability to have greater interactions with the FDA, the FDA may initiate review of sections of a Fast Track NDA or BLA before the application is complete, a process known as rolling review.

The FDA may give a priority review designation, such as a rare pediatric disease designation, to drug or biological products that treat a serious condition and, if approved, would provide a significant improvement in safety or effectiveness. A priority review means that the goal for the FDA to review an application is six months, rather than the standard review of ten months under current PDUFA guidelines. Most products that are eligible for fast track designation may also be considered appropriate to receive a priority review. In addition, drug and biological products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may receive accelerated approval and may be approved on the basis of adequate and well-controlled clinical trials establishing that the drug or biological 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 approval, the FDA may require a sponsor of a drug or biological product receiving accelerated approval to perform post-marketing studies to verify and describe the predicted effect on irreversible morbidity or mortality or other clinical endpoint, and the drug or biological product may be subject to accelerated withdrawal procedures.

Moreover, under the Food and Drug Administration Safety and Innovation Act enacted in 2012, a sponsor can request designation of a product candidate as a “breakthrough therapy.” A breakthrough therapy is defined as a drug or biological product 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 or biological product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Drug and biological products designated as breakthrough therapies are also eligible for accelerated approval. The FDA must take certain actions, such as holding timely meetings and providing advice, intended to expedite the development and review of an application for approval of a breakthrough therapy.

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 decides that the time period for FDA review or approval will not be shortened. Furthermore, fast-track designation, priority review, accelerated approval and breakthrough therapy designation, do not change the standards for approval and may not ultimately expedite the development or approval process.

Biologics Price Competition and Innovation Act

The Biologics Price Competition and Innovation Act of 2009 ("BPCIA"), which was enacted as part of the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010 ("PPACA"), created an abbreviated approval pathway for biological products that are demonstrated to be “biosimilar” or “interchangeable” with an FDA-licensed reference biological product via an approved BLA. Biosimilarity to an approved reference product requires that there be no differences in conditions of use, route of administration, dosage form, and strength, and no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and potency. Biosimilarity is demonstrated in steps beginning with rigorous analytical studies or “fingerprinting”, in vitro studies, in vivo animal studies, and generally at least one clinical study, absent a waiver from the Secretary of Health and Human Services. The biosimilarity exercise tests the hypothesis that the investigational product and the reference product are the same. If at any point in the stepwise biosimilarity process a significant difference is observed, then the products are not biosimilar, and the development of a stand-alone NDA or BLA is necessary. In order to meet the higher hurdle of interchangeability, a sponsor must demonstrate that the biosimilar product can be expected to produce the same clinical result as the reference product, and for a product that is administered more than once, that the risk of switching between the reference product and biosimilar product is not greater than the risk of maintaining the patient on the reference product. Complexities associated with the larger, and often more complex, structures of biological products, as well as the process by which such products are manufactured, pose significant hurdles to implementation that are still being evaluated by the FDA. Under the BPCIA, a reference biologic is granted 12 years of exclusivity from the time of first licensure of the reference product.

18

Regulation Outside of the United States

In addition to regulations in the United States, we are subject to a variety of regulations in other jurisdictions governing clinical studies, commercial sales, and distribution of our products. Most countries outside of the United States require that clinical trial applications be submitted to and approved by the local regulatory authority for each clinical study. In addition, whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of countries outside the U.S. before it can commence clinical studies or marketing of the product in those countries. The approval process and requirements vary from country to country, so the number and type of nonclinical, clinical, and manufacturing studies needed may differ, and the time may be longer or shorter than that required for FDA approval.

To obtain regulatory approval of an orphan drug under the EU regulatory system, we are mandated to submit a Marketing Authorization Application ("MAA") to be assessed in the Centralized Procedure. The centralized procedure, which came into operation in 1995, allows applicants to obtain a marketing authorization that is valid throughout the EU. It is compulsory for medicinal products manufactured using biotechnological processes, for orphan medicinal products and for human products containing a new active substance which was not authorized in the Community before 20 May 2004 (date of entry into force of Regulation (EC) No 726/2004) and which are intended for the treatment of AIDS, cancer, neurodegenerative disorder or diabetes. The centralized procedure is optional for any other products containing new active substances not authorized in the Community before 20 May 2004 or for products which constitute a significant therapeutic, scientific or technical innovation or for which a Community authorization is in the interests of patients at Community level. When a company wishes to place on the market a medicinal product that is eligible for the centralized procedure, it sends an application directly to the European Medicines Agency ("EMA"), to be assessed by the Committee for Medicinal Products for Human Use ("CHMP"). The CHMP is responsible for conducting the assessment of whether a medicine meets the required quality, safety and efficacy requirements, and whether the product has a positive risk/benefit/risk profile. The procedure results in a Commission decision, which is valid in all EU Member States. Centrally-authorized products may be marketed in all Member States.

Centralized Procedure: Full copies of the MAA are sent to a rapporteur and a co-rapporteur designated by the competent EMA scientific committee. They coordinate the EMA’s scientific assessment of the medicinal product and prepare draft reports. Once the draft reports are prepared (other experts might be called upon for this purpose), they are sent to the CHMP, whose comments or objections are communicated to the applicant. The rapporteur is therefore the privileged interlocutor of the applicant and continues to play this role, even after the MA has been granted.

The rapporteur and co-rapporteur then assess the applicant’s replies, submit them for discussion to the CHMP and, taking into account the conclusions of this debate, prepare a final assessment report. Once the evaluation is completed, the CHMP gives a favorable or unfavorable opinion as to whether to grant the authorization. When the opinion is favorable, it shall include the draft summary of the product’s characteristics, the package leaflet and the texts proposed for the various packaging materials. The time limit for the evaluation procedure is 210 days. The EMA then has fifteen days to forward its opinion to the Commission. This is the start of the second phase of the procedure: the decision-making process. The Agency sends to the Commission its opinion and assessment report, together with annexes containing: the SmPC ("Annex 1"); the particulars of the MAH responsible for batch release, the particulars of the manufacturer of the active substance and the conditions of the marketing authorization ("Annex 2"); and the labelling and the package leaflet ("Annex 3"). The annexes are translated into the 22 other official languages of the EU. During the decision-making process, the Commission services verify that the marketing authorization complies with Union law. The Commission has fifteen days to prepare a draft decision. The medicinal product is assigned a Community registration number, which will be placed on its packaging if the marketing authorization is granted. During this period, various Commission directorates-general are consulted on the draft marketing authorization decision.

The draft decision is then sent to the Standing Committee on Medicinal Products for Human Use (Member States have one representative each in both of these committees) for their opinions. The Centralized Procedure provides for the grant of a single marketing authorization that is valid for all EU member states.

Applications from persons or companies seeking “orphan medicinal product designation” for products they intend to develop for the diagnosis, prevention, or treatment of life-threatening or very serious conditions that affect not more than five in 10,000 persons in the EU are reviewed by the Committee for Orphan Medicinal Products ("COMP"). In addition, orphan drug designation can be granted if the drug is intended for a life threatening, seriously debilitating, or serious and chronic condition in the EU and that without incentives it is unlikely that sales of the drug in the EU would be sufficient to justify developing the drug. Orphan drug designation is only available if there is no other satisfactory method approved in the EU of diagnosing, preventing, or treating the condition, or if such a method exists, the proposed orphan drug will be of significant benefit to patients.

19

Orphan drug designation provides opportunities for fee reductions, protocol assistance and access to the centralized procedure before and during the first year after marketing approval. Fee reductions are not limited to the first year after marketing approval for small and medium enterprises. In addition, if a product which has an orphan drug designation subsequently receives EMA marketing approval for the indication for which it has such designation, the product is entitled to orphan market exclusivity, which means the EMA may not approve any other application to market a similar drug for the same indication for a period of ten years. The exclusivity period may be reduced to six years if the designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity. Competitors may receive marketing approval of different drugs or biologics for the indications for which the orphan product has exclusivity. In order to do so, however, they must demonstrate that the new drugs or biologics are clinically superior over the existing orphan product. This demonstration of clinical superiority may be done at the time of initial approval or in post-approval studies, depending on the type of marketing authorization granted.

In March 2016, the EMA launched an initiative, The Priority Medicines ("PRIME") scheme, to facilitate development of product candidates in indications, often rare, for which few or no therapies currently exist. The PRIME scheme is intended to encourage drug development in areas of unmet medical need and provides accelerated assessment of products representing substantial innovation reviewed under the centralized procedure. Many benefits accrue to sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs and other development program elements, and accelerated MAA assessment once a dossier has been submitted. Importantly, a dedicated contact and rapporteur from the CHMP is appointed early in the PRIME scheme facilitating increased understanding of the product at EMA’s committee level. An initial meeting initiates these relationships and includes a team of multidisciplinary experts at the EMA to provide guidance on the overall development and regulatory strategies.

The U.K. left the EU on January 31, 2020 following which, existing EU medicinal product legislation continued to apply in the U.K. during the transition period under the terms of the EU-UK Withdrawal Agreement. A transition period, which ended on December 31, 2020, maintained access to the EU single market and to the global trade deals negotiated by the EU on behalf of its members. The transition period provided time for the U.K. and EU to negotiate a framework for partnership for the future, which was then crystallized in the Trade and Cooperation Agreement ("TCA") and became effective on January 1, 2021.

From January 1, 2021, the Medicines and Healthcare products Regulatory Agency ("MHRA") will be the U.K.’s standalone medicines and medical devices regulator. As a result of the Northern Ireland protocol, different rules will apply in Northern Ireland than in England, Wales and Scotland (together "Great Britain", or "GB"); broadly, Northern Ireland will continue to follow the EU regulatory regime, but its national competent authority will remain the MHRA. The MHRA has published a draft guidance on how various aspects of the U.K. regulatory regime for medicines will operate in GB and in Northern Ireland following the expiry of the Brexit transition period on December 31, 2020. The guidance includes clinical trials, marketing authorizations, importing, exporting and pharmacovigilance and is relevant to any business involved in the research, development or commercialization of medicines in the U.K. The new guidance will be given effect via the Human Medicines Regulations (Amendment etc.) (EU Exit) Regulations 2019 (the "Exit Regulations"). The U.K. regulatory regime largely mirrors that of the EU.

The MHRA has introduced changes to national licensing procedures, including procedures to prioritize access to new medicines that will benefit patients, an accelerated assessment procedure and new routes of evaluation for novel products and biotechnological products. All existing E.U. MAs for centrally authorized products were automatically be converted (grandfathered) into U.K. MAs free-of-charge on January 1, 2021.

There will be no pre-marketing authorization orphan designation. Instead, the MHRA will review applications for orphan designation in parallel to the corresponding MA application. The criteria are essentially the same, but have been tailored for the GB market, i.e. the prevalence of the condition in GB (rather than the EU) must not be more than 5 in 10,000. Should an orphan designation be granted, the period for market exclusivity will be set from the date of first approval of the product in GB or EU/European Economic Area, wherever is earliest.

Healthcare Laws and Regulations

Sales of our product candidate, if approved, or any other future product candidate will be subject to healthcare regulation and enforcement by the federal government and the states and foreign governments in which we might conduct our business. The healthcare laws and regulations that may affect our ability to operate include the following:

Many states have similar laws and regulations, such as anti-kickback and false claims laws that may be broader in scope and may apply regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs. Additionally, we may be subject to state laws that require pharmaceutical companies to comply with the federal government’s and/or pharmaceutical industry’s voluntary compliance guidelines, state 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, as well as state and foreign laws governing the privacy and security of health information, many of which differ from each other in significant ways and often are not preempted by HIPAA. Additionally, to the extent that our products are sold in a foreign country, we may be subject to similar foreign laws.

21

Healthcare Reform

The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the healthcare system. The United States government, state legislatures and foreign governments also have shown significant interest in implementing cost-containment programs to limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement and requirements for substitution of generic products for branded prescription drugs. In recent years, Congress has considered reductions in Medicare reimbursement levels for drugs administered by physicians. CMS, the agency that administers the Medicare and Medicaid programs, also has authority to revise reimbursement rates and to implement coverage restrictions for some drugs. Cost reduction initiatives and changes in coverage implemented through legislation or regulation could decrease utilization of and reimbursement for any approved products. While Medicare regulations apply only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that results from federal legislation or regulation may result in a similar reduction in payments from private payors.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or collectively the Affordable Care Act (the “ACA”), substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacts the pharmaceutical industry. The Affordable Care Act is intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against healthcare fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new taxes and fees on pharmaceutical and medical device manufacturers, and impose additional health policy reforms.

There have been significant ongoing efforts to modify or eliminate the Affordable Care Act. On January 20, 2017, former President Trump signed an executive order directing federal agencies to exercise existing authorities to reduce burdens associated with the ACA pending further action by Congress. In October 2017, he signed an Executive Order which directed federal agencies to modify how the ACA is implemented. The Tax Act, enacted on December 22, 2017, repealed the shared responsibility payment for individuals who fail to maintain minimum essential coverage under Section 5000A of the Internal Revenue Code of 1986, as amended ("IRC"), commonly referred to as the individual mandate.

Other legislative changes have been proposed and adopted since passage of the ACA. The Budget Control Act of 2011, among other things, created the Joint Select Committee on Deficit Reduction to recommend proposals in spending reductions to Congress. The Joint Select Committee did not achieve its targeted deficit reduction of an amount greater than $1.2 trillion for the fiscal years 2012 through 2021, triggering the legislation’s automatic reductions to several government programs. These reductions included aggregate reductions to Medicare payments to healthcare providers of up to 2.0% per fiscal year, which went into effect in April 2013. Subsequent litigation extended the 2% reduction, on average, to 2030 unless additional Congressional action is taken. However, pursuant to the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act"), the 2% Medicare sequester reductions have been suspended from May 1, 2020 through March 31, 2021 due to the COVID-19 pandemic.

Further legislative and regulatory changes under the ACA remain possible, although the Biden Administration has signaled that it plans to build on the ACA and expand the number of people who are eligible for subsidies under it. President Biden indicated that he intends to use executive orders to undo changes to the ACA made by the former administration and would advocate for legislation to build on the ACA. It is unknown what form any such changes or any law would take, and how or whether it may affect our business in the future. We expect that changes or additions to the ACA, the Medicare and Medicaid programs, changes allowing the federal government to directly negotiate drug prices and changes stemming from other healthcare reform measures, especially with regard to healthcare access, financing or other legislation in individual states, could have a material adverse effect on the healthcare industry.

The ACA has been subject to challenges in the courts. On December 14, 2018, a Texas U.S. District Court judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. On December 18, 2019, the U.S. Court of Appeals for the Fifth Circuit held that the individual mandate is unconstitutional and remanded the case to the Texas District Court to reconsider its earlier invalidation of the entire ACA. An appeal was taken to the Supreme Court, which heard oral arguments in the case on November 10, 2020. On June 17, 2021, the Supreme Court upheld the ACA and dismissed the case.

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.

We expect that additional federal, state and foreign healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in limited coverage and reimbursement and reduced demand for our products, once approved, or additional pricing pressures.

Employees and Human Capital Resources

Our mission is to deliver innovative precision therapies to improve the lives of patients and families battling genetically-driven cardiovascular and mechanistically-related diseases. Accordingly, we are building a team who is passionate about our mission and establishing a culture where patients are at the center of all we do, with core values that connect us to each other and our stakeholders, and define who we are, what we stand for, and how we work.

As of March 15, 2022, we had 19 full-time employees, including our Chief Executive Officer, Magdalene Cook, M.D., our Chief Medical Officer, Marc Semigran, M.D., our Chief Scientific Officer, Matt Killeen, Ph.D., and 16 other individuals, 12 of whom are engaged in research and development. Of our 19 full-time employees, 11 have Ph.D. or M.D. degrees and 14 are engaged in research and development activities. None of our employees are represented by labor unions or covered by collective bargaining agreements, and we consider our relationship with employees to be good. We also utilize the services of several independent consultants to support our R&D and G&A operations, including our Interim CFO, Wendy DiCicco.

We are focused on effective identification, recruitment, development, and retention of, and compensation and benefits to, human resource talent, including workforce and management development, diversity and inclusion initiatives, succession planning, and corporate culture and leadership quality, which are vital to our success. The principal purposes of our equity incentive plans are to attract, retain and motivate selected employees, consultants and directors through the granting of stock-based compensation awards and cash-based performance bonus awards.

We anticipate hiring additional employees that could result in a total of up to approximately 50 full-time employees by the end of 2022, across R&D and G&A operations.

Item 1A. Risk Factors.

Investing in our securities involves a high degree of risk. You should consider carefully the risks and uncertainties described below, together with all of the other information in this Annual Report on Form 10-K, including the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes, before deciding whether to purchase any of our securities. If any of the following risks actually occurs, our business, financial condition or results of operations would likely suffer. In such case, the trading price of our securities (including our common stock, par value $0.0001 per share ("Common Stock)) could decline due to any of these risks, and you may lose all or part of your investment. Unless the context indicates otherwise, references in this section to the “Company,” “Renovacor,” “we,” “us,” “our” and similar terms refer to Renovacor, Inc. (f/k/a Chardan Healthcare Acquisition 2 Corp.) and our consolidated subsidiaries. References to “Chardan” refer to our predecessor company prior to the consummation of the Business Combination. References to “Old Renovacor” refer to Renovacor, Inc. prior to the consummation of the Business Combination and to Renovacor Holdings, Inc. (f/k/a Renovacor, Inc.), now the wholly owned subsidiary of Renovacor, upon the consummation of the Business Combination.

Risks Related to Our Financial Position and Capital Requirements

Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

We are a preclinical-stage gene therapy company with a limited operating history on which to base your investment decision. Our operations to date have been limited to organizing and staffing the company, in-licensing key intellectual property, business planning, raising capital, conducting discovery and research activities, filing and prosecuting patent applications, identifying potential product candidates and preparing to initiate and conduct clinical trials, undertaking preclinical studies, and establishing processes and arrangements with third parties for the manufacture of initial quantities of our lead product candidate and component materials necessary for our planned Phase I/II clinical trial. Our lead product candidate is still in the preclinical development phase and other planned product candidates are in the discovery and research phase. We do not expect to submit an IND for REN-001 or any other product candidate until the second half of 2022. We have not yet demonstrated our ability to successfully commence or complete a clinical trial, submit an IND, or submit a biologics license application ("BLA"), for a product candidate, obtain regulatory approval for any product candidate, manufacture a product at a commercial-scale or arrange for a third party to do so on our behalf, or conduct sales, marketing and distribution activities necessary for successful product commercialization. Consequently, any assumptions you make about our future success or viability may not be as informed as they could be if we had a longer operating history.

We have incurred significant operating losses since our inception and expect to incur significant losses for the foreseeable future.

We have incurred significant operating losses since our inception. If our product candidates are not successfully developed and approved, we may never generate any revenue. Our net losses were $14.1 million and $3.2 million for the years ended December 31, 2021 and 2020, respectively. We had an accumulated deficit of $19.0 million as of December 31, 2021. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. All of our product candidates will require the expenditure of substantial additional development time and resources before we would be able to apply for or receive regulatory approvals and begin realizing product sales. We expect to continue to incur losses for the foreseeable future, and we anticipate these losses will significantly increase as we continue our development of, seek regulatory approval for and potentially commercialize any of our product candidates and seek to identify, assess, acquire, in-license or develop additional product candidates. Our prior losses, combined with expected future losses, have had and will continue to have a negative effect on our stockholders’ deficit and working capital.

We expect that it will be several years, if ever, before we have a commercialized product. We anticipate our expenses will increase substantially if, and as, we:

24

We may never succeed in any or all of these activities and, even if we do, we may never generate revenue.

We have never generated revenue from product sales and may never achieve or maintain profitability.

We have no product candidates in clinical development or approved for commercial sale and have not generated any revenue. To become and remain profitable, we must develop and eventually commercialize product candidates with significant market potential, which will require being successful in a range of challenging activities. These activities can include successfully completing preclinical studies and initiating and successfully completing clinical trials of our product candidates, obtaining marketing approval for these product candidates, manufacturing, marketing and selling those products that are approved and satisfying any post-marketing requirements. We may never succeed in any or all of these activities and, even if we do, we may never generate sufficient revenues to achieve profitability. Because of the numerous risks and uncertainties associated with biologics product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability.

Even if we do achieve profitability, we may not be able to sustain or increase profitability. Our failure to become and remain profitable would decrease the value of the Company and could impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations.

We will require additional funding in order to finance operations. If we are unable to raise capital when needed, or on acceptable terms, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.

Developing biopharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive and uncertain process that takes years to complete. Our operations have consumed substantial amounts of cash since inception, and we expect our expenses to increase significantly in connection with our ongoing activities, particularly as we conduct additional preclinical studies and clinical trials of, and seek regulatory and marketing approval for, our product candidates. Even if one or more of our product candidates is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product candidate. We have financed our operations primarily through private placements of our securities and the Business Combination. We intend to use the additional capital made available to us to, among other uses, fund research and development of our product candidates and development programs, including the preclinical and clinical development of our lead product candidate, REN-001, with an initial focus on patients with BAG3 DCM, as well as additional indications that may benefit from BAG3-based gene therapy. Our research and development expenses increased from $2.4 million for the year ended December 31, 2020 to $11.8 million for the year ended December 31, 2021. As of December 31, 2021, we had $78.8 million of cash and cash equivalents. Based on our current business plans, we believe this will be sufficient for us to fund our operating expenses and capital expenditure requirements into the second half of 2023.

Attempting to secure additional financing will divert the company’s management team from day-to-day activities, which may impair or delay our ability to develop our product candidates. In addition, demands on our cash resources may change as a result of many factors currently unknown to us including, but not limited to, any unforeseen costs we may incur as a result of preclinical study or clinical trial delays due to the COVID-19 pandemic or other causes, and we may need to seek additional funds sooner than planned. If we are unable to obtain funding on a timely basis or at all, we may be required to significantly curtail or stop one or more of our research or development programs.

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

Until and unless we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings and debt financings, and potentially through additional license and development agreements or strategic partnerships or collaborations with third parties. Financing may not be available in sufficient amounts or on reasonable terms. In addition, market volatility resulting from the COVID-19 pandemic or other factors could adversely impact our ability to access capital as and when needed. We have no commitments for any additional financing, and will likely be required to raise such financing through the sale of additional securities. If we sell equity or equity-linked securities, our current stockholders may be diluted, and the terms may include

25

liquidation or other preferences that are senior to or otherwise adversely affect the rights of our stockholders. Moreover, if we issue debt, we may need to dedicate a substantial portion of our operating cash flow to paying principal and interest on such debt and we may need to comply with operating restrictions, such as limitations on incurring additional debt, which could impair our ability to acquire, sell or license intellectual property rights which could impede our ability to conduct our business. Furthermore, the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our Common Stock to decline.

If we raise additional funds through licensing or collaboration arrangements with third parties, we may have to relinquish valuable rights to our product candidates, or grant licenses on terms that are not favorable. 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.

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

As of December 31, 2021, we had approximately $18.5 million of federal net operating loss carryforwards, and approximately $20.1 million of state apportioned net operating loss carryforwards. To the extent that we continue to generate taxable losses, unused losses will carryforward to offset future taxable income, if any, until such unused losses expire. Under Section 382 of the Internal Revenue Code of 1986, as amended (the "IRC"), if a corporation undergoes an ownership change (generally defined as a greater than 50 percentage points change (by value) in our equity ownership over a rolling three-year period), the corporation’s ability to use its pre-change net operating losses and other pre-change tax attributes to offset our post-change income may be limited. To date, we have not yet conducted a study to assess whether a "ownership change" as defined in the IRC has occurred as a result of the Business Combination or other changes in ownership since its inception. We intend to complete a Section 382 limitation study in 2022, prior to the filing of the our federal and state corporate income tax returns, and the result of such study may affect our ability to utilize our net operating loss carryforwards. In addition, we may experience ownership changes in the future, including subsequent shifts in our stock ownership, some of which are outside our control. Similar limitations will apply to our ability to carry forward any unused tax credits to offset future taxable income. Federal net operating loss carryforwards generated in taxable years beginning after December 31, 2017 will not be subject to expiration. However, any such net operating loss carryforwards may only offset 80% of our annual taxable income in taxable years beginning after December 31, 2017.

Changes in tax law, in our tax rates or in exposure to additional income tax liabilities or assessments may materially and adversely affect our financial condition, results of operations and cash flows.

Changes in law and policy relating to taxes may materially and adversely affect our financial condition, results of operations and cash flows. For example, on March 27, 2020 the U.S. enacted the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act"). The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, NOL carryback periods, alternative minimum tax credit refunds, modification to the net interest deduction limitations, and technical corrections to tax depreciation methods for qualified improvement property.

The U.S. also enacted the Tax Cuts and Jobs Act of 2017 (the "2017 Tax Act") on December 22, 2017, which significantly changed the U.S. federal income taxation of U.S. corporations. The 2017 Tax Act remains unclear in many respects and has been, and may continue to be, the subject of amendments and technical corrections, as well as interpretations and implementing regulations by the Treasury and IRS, which have mitigated or increased certain adverse impacts of the 2017 Tax Act and may continue to do so in the future. In addition, it is unclear how certain of these U.S. federal income tax changes will affect state and local taxation, which often uses federal taxable income as a starting point for computing state and local tax liabilities. We continue to examine the impact the CARES Act and the 2017 Tax Act may have on our business in future quarters. The U.S. Congress is currently considering other legislative proposals, including increasing the U.S. federal income tax rate on corporations like us, which, if enacted, could materially impact our financial condition and cash flows in the future.

The COVID-19 pandemic, or a similar pandemic, epidemic, or outbreak of an infectious disease, may materially and adversely affect our business and our financial results and could cause a disruption to the development of our product candidates.

Public health crises, such as pandemics or similar outbreaks, could adversely impact our business. A novel virus, severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2, which causes COVID-19 has spread to most countries across the world, including the United States. The coronavirus pandemic is evolving and has led to the implementation of various responses, including government-imposed quarantines, travel restrictions and other public health safety measures. The extent to which the coronavirus impacts our operations or those of our consultants and collaborators will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, new information that will emerge concerning the

26

severity of the coronavirus, new strains or mutations of the coronavirus and the actions to contain the coronavirus or treat its impact, among others.

As a result of the coronavirus pandemic, or similar pandemics, we may experience disruptions that could severely impact our business, manufacturing, preclinical development activities and preclinical studies, including, but not limited to:

We have not yet commenced clinical trial activities for any of our product candidates. If we commence clinical trials for one or more of our product candidates, potential disruptions of those clinical activities as a result of the coronavirus pandemic or similar pandemics, include, but are not limited to:

The coronavirus pandemic continues to rapidly evolve, including as a result of new variants of COVID-19, such as the delta and omicron variants. Although many countries, including the United States, have experienced declining cases and increased vaccination rates, rises in new cases have caused certain countries, states and local geographic regions to re-initiate restrictions. The extent to

27

which the outbreak may affect our preclinical studies, clinical trials, business, financial condition, and results of operations will depend on future developments, which are highly uncertain and cannot be predicted at this time, such as the ultimate geographic spread of the disease, the duration of the outbreak, vaccination rates and efficacy, travel restrictions, and actions to contain the outbreak or treat its impact, such as social distancing and quarantines or lock-downs 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. Additionally, we are unable to predict if a different pandemic could have similar or different impacts on our business, financial condition, or share price. Future developments in these and other areas present material uncertainty and risk with respect to our clinical trials, business, financial condition, and results of operations.

Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price.

Global financial markets have experienced, as a result of the coronavirus pandemic, and have in the past experienced, extreme volatility and disruptions, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability.

Our general business strategy may be adversely affected by such economic conditions or the presence of a volatile business environment or unpredictable and unstable market conditions, such as the economic turmoil resulting from the spread of the ongoing COVID-19 pandemic and the current conflict between Russia and Ukraine. Further, the impacts of political unrest, including as a result geopolitical tension, such as a deterioration in the relationship between the U.S. and China or escalation in conflict between Russia and Ukraine, including any additional sanctions, export controls or other restrictive actions that may be imposed by the U.S. and/or other countries against governmental or other entities in, for example, Russia, also could lead to disruption, instability and volatility in the global markets, which may have an adverse impact on our business or ability to access the capital markets. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. If the current equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to delay or abandon the development of preclinical studies and clinical trial plans. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not survive these difficult economic times, which could directly affect our ability to attain our operating goals on schedule and on budget.

In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies, including very recently in connection with the ongoing coronavirus pandemic, which has resulted in decreased stock prices for many companies notwithstanding the lack of a fundamental change in their underlying business models or prospects. These fluctuations have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors, including potentially worsening economic conditions and other adverse effects or developments relating to the ongoing coronavirus pandemic, political, regulatory and other market conditions, may negatively affect the market price of shares of our Common Stock, regardless of our actual operating performance.

Risks Related to Our Product Development and Government Regulation

We are very early in our research and development efforts. Our business is dependent on our ability to advance our current and future product candidates through preclinical studies and clinical trials, obtain marketing approval and ultimately commercialize them.

We are very early in our research and development efforts and all of our product candidates are still at the preclinical stage of development. We expect to submit an IND with respect to our lead product candidate REN-001 in the second half of 2022. Additionally, we have earlier stage programs that are in the discovery research phase and may never advance to clinical-stage development. Our ability to generate product revenue, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual commercialization of our product candidates, which may never occur. We currently generate no revenue from sales of any product and we may never be able to develop or commercialize a marketable product.

Each of our programs and product candidates will require additional preclinical and clinical development, regulatory approval in multiple jurisdictions, obtaining manufacturing supply, capacity and expertise, building a commercial organization or successfully outsourcing commercialization, substantial investment and significant marketing efforts before we generate any revenue from product sales. Our product candidates must be authorized for marketing by the FDA, or certain other foreign regulatory agencies before we may commercialize our product candidates.

28

The clinical and commercial success of our product candidates will depend on several factors, including the following:

If we do not succeed in one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize our product candidates, which would materially harm our business. If we are unable to advance our product candidates to clinical development, obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed.

Our business is highly dependent on the success of our lead product candidate, REN-001, and our other product candidates.

We cannot guarantee that, based on our IND application for REN-001 or our other product candidates, the FDA, or any other comparable foreign regulatory authorities, will allow clinical trials to commence, or that REN-001 or our other product candidates will be approved for commercialization, on a timely basis or at all. We have not initiated and, therefore, have not previously completed any clinical trials or submitted an IND or a BLA to the FDA, or similar regulatory approval filings to comparable foreign authorities, for any product candidate, and we cannot be certain that REN-001 or our other product candidates will be successful in clinical trials or receive regulatory approval. The FDA and other comparable global regulatory authorities can delay, limit or deny approval of a product candidate for many reasons. Any delay in obtaining, or inability to obtain, applicable regulatory approval will delay or harm our ability to successfully initiate clinical trials and commercialize REN-001 or our other product candidates and materially adversely affect our business, financial condition, results of operations and growth prospects.

Furthermore, because REN-001 is our lead product candidate and our other product candidates could be based on similar technology, if clinical trials of REN-001 encounter safety, efficacy or manufacturing problems, development delays, regulatory issues or other problems, our development plans for REN-001 and our other product candidates in our pipeline based on similar technology would be significantly impaired, which could materially adversely affect our business, financial condition, results of operations and growth prospects.

Our business depends upon the success of our BAG3-based platform.

Our success depends on our ability to utilize the exclusive rights to our BAG3-based platform to identify potential product candidates, to obtain regulatory approval for product candidates derived from the platform, and then to commercialize our product candidates addressing one or more indications. Though gene therapy product candidates have been evaluated by others in clinical trials using similar AAV vectors, our product candidates have never been evaluated in human clinical trials, and may experience unexpected or

29

adverse results in the future. We are exposed to a number of unforeseen risks and it is difficult to predict the types of challenges and risks that we may encounter during development of our product candidates. All of our product candidates developed from our BAG3-based platform will require significant non-clinical studies, clinical development, review and approval by the FDA or other regulatory authorities in one or more jurisdictions, substantial investment, access to sufficient commercial manufacturing capacity and significant marketing efforts before they can be successfully commercialized. If REN-001 or any of our other product candidates encounter safety or efficacy problems, developmental delays or regulatory issues or other problems, such problems could impact the development plans for our other product candidates because all of our product candidates are currently based on the same core BAG3-based technology.

Additionally, a key element of our strategy is to use and expand our BAG3-based platform to build a pipeline of product candidates and progress those product candidates through clinical development for the treatment of a variety of different types of indications in heart failure and central nervous system diseases. Although our research and development efforts to date have been focused on identifying a pipeline of product candidates, we may not be able to develop product candidates that are safe and effective. Even if we are successful in building 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 approvable or marketable products that will receive marketing approval/authorization and achieve market acceptance. If we do not successfully develop, get approval for and begin to commercialize any product candidates, we will face difficulty in obtaining product revenue in future periods, which would result in significant harm to our financial position and adversely affect our share price.

Utilizing AAV/BAG3-based gene therapies to target BAG3 mutations represents a novel approach to the treatment of DCM, and we must overcome significant challenges in order to develop, commercialize and manufacture our product candidates.

We have concentrated our research and development efforts on developing AAV/BAG3-based gene therapies to target BAG3 mutations for the treatment of DCM. We are aware of several companies developing gene therapies targeting heart failure but are not aware of any companies developing gene therapies targeting the BAG3 pathway for patients suffering from BAG3 DCM. The processes and requirements imposed by the FDA or other applicable regulatory authorities may cause delays and additional costs in obtaining approvals for REN-001 and our other product candidates. Because our AAV/BAG3-based gene therapy products are novel, and gene-based therapies are relatively new, regulatory agencies may lack experience in evaluating our product candidates utilizing AAV/BAG3-based gene therapies to target BAG3 mutations for patients suffering from BAG3 DCM. This novelty may lengthen the regulatory review process, including the time it takes for the FDA to review our IND applications, if and when submitted, increase our development costs and delay or prevent commercialization of our AAV/BAG3-based gene therapy products. Additionally, advancing novel gene therapies creates significant challenges for us, including:

We must be able to overcome these challenges in order for us to develop, commercialize and manufacture our product candidates utilizing AAV/BAG3 gene therapies for our targeted indications.

The product candidates for which we intend to seek approval as biologic products may face competition sooner than anticipated.

The Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010 (the "ACA") includes a subtitle called the Biologics Price Competition and Innovation Act of 2009 (the "BPCIA"), which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application for a highly similar or “biosimilar” product may not be submitted to the FDA until 12 years following the date that the reference product was first approved 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 approved. 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 the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity, and potency of their product. 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. In

30

addition, complexities associated with the larger, and often more complex, structures of biological products, such as the gene products we are developing, 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.

We believe that any of our product candidates approved as a biological 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 competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. 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-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.

Jurisdictions in addition to the United States have established abbreviated pathways for regulatory approval of biological products that are biosimilar to earlier approved reference products. For example, the European Union has had an established regulatory pathway for biosimilars since 2004. However, biosimilars can only be authorized once the period of data exclusivity on the reference biological medicine has expired.

The increased likelihood of biosimilar competition has increased the risk of loss of innovators’ market exclusivity. Due to this risk, and uncertainties regarding patent protection, if our clinical candidates are approved for marketing, it is not possible to predict the length of market exclusivity for any particular product with certainty based solely on the expiration of the relevant patent(s) or the current forms of regulatory exclusivity. It is also not possible to predict changes in United States regulatory law that might reduce biological product regulatory exclusivity. The loss of market exclusivity for a product would likely materially and negatively affect revenues and we may not generate adequate or sufficient revenues from them or be able to reach or sustain profitability.

Preclinical and clinical development involve a lengthy and expensive process with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our current product candidates or any future product candidates.

REN-001 and all of our other product candidates are in the preclinical stage of development and their risk of failure is high. It is impossible to predict when or if REN-001 or any of our other product candidates will receive regulatory approval. To obtain the requisite regulatory approvals to commercialize any product candidate, we must demonstrate through extensive preclinical studies and lengthy, complex and expensive clinical trials that our product candidates are safe and effective in humans. Clinical testing can take many years to complete, and the outcome is inherently uncertain. Failure can occur at any time during the clinical trial process.

The results of preclinical studies and early clinical trials or early cohorts of clinical trials of product candidates may not be predictive of the results of later-stage clinical trials or later cohorts of clinical trials. We anticipate beginning our initial clinical trials with relatively small cohorts before expanding in size in subsequent cohorts. The initial cohorts of early stage clinical trials often involve enrollment of a small number of patients and may not be as predictive as trials with larger cohorts. Additionally, if safety issues arise in an early cohort, we may be delayed or prevented from subsequently expanding into larger trial cohorts. We may be unable to establish clinical endpoints that applicable regulatory authorities would consider clinically meaningful, and a clinical trial can fail at any stage of testing. Differences in trial design between early-stage clinical trials and later-stage clinical trials make it difficult to extrapolate the results of earlier clinical trials to later clinical trials.

Moreover, clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of their products. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or to unfavorable safety profiles, notwithstanding promising results in earlier trials. There is typically a high rate of failure of product candidates proceeding through clinical trials. Most product candidates that commence clinical trials are never approved as products and there can be no assurance that any of our future clinical trials will ultimately be successful or support clinical development of our current or any of our future product candidates.

We may experience delays in initiating or completing clinical trials. We also may experience numerous unforeseen events during, or as a result of, any future clinical trials that we could conduct that could delay or prevent our ability to receive marketing approval or commercialize our lead product candidate or any future product candidates, including:

31

Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population, the number and location of clinical sites we enroll, the proximity of patients to clinical sites, the eligibility and exclusion criteria for the trial, the design of the clinical trial, the inability to obtain and maintain patient consents, the risk that enrolled participants will drop out before completion, competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new drugs or therapeutic biologics that may be approved for the indications being investigated by it. Furthermore, we expect to rely on our collaborators, CROs and clinical trial sites to ensure the proper and timely conduct of our future clinical trials, including the patient enrollment process, and we have limited influence over their performance. Additionally, we could encounter delays if treating physicians encounter unresolved ethical issues associated with enrolling patients in future clinical trials of our product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles.

We could also encounter delays if a clinical trial is suspended or terminated by us, the IRBs of the institutions in which such trials are being conducted, or the FDA or other regulatory authorities, or if a clinical trial is recommended for suspension or termination by the Data Safety Monitoring Board for such trial. A suspension or termination may be imposed due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or clinical protocols, inspection of the clinical trial operations or trial site by the FDA 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 or treatment, failure to establish or achieve clinically meaningful trial endpoints, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Clinical studies may also be delayed or terminated as a result of ambiguous or negative interim results. 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. Further, the FDA or other regulatory authorities may disagree with our clinical trial design and our interpretation of data from clinical trials, or may change the requirements for approval even after they have reviewed and commented on the design for our clinical trials.

32

Our product development costs will increase if we experience delays in clinical testing or marketing approvals. We do not know whether any of our clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates and may allow our competitors to bring products to market before we do, potentially impairing our ability to successfully commercialize our product candidates and harming our business and results of operations. Any delays in our clinical development programs may harm our business, financial condition and results of operations significantly.

There is no guarantee that the toxicology and biodistribution studies in healthy pigs and the efficacy studies in haploinsufficient mice will be successful, or that the FDA will not require further testing in these or other animal models.

Preclinical studies involve a lengthy and expensive process with an uncertain outcome. Some outcomes may demonstrate the need to conduct studies in different animal models or using different protocols. These outcomes may lead us to incur additional costs or experience delays in completing, or render us unable to complete, the development and commercialization of our current product candidates or any future product candidates.

We conducted a pilot study in infarcted pigs to assess the transduction efficiency and functional effect of REN-001. We later concluded that an infarcted pig model is untenable for further efficacy studies due to the variability of the infarcted phenotype and the development of neutralizing antibodies to AAV in the study animals during the study.

There is no guarantee that ongoing or future toxicology and biodistribution studies in healthy pigs and the efficacy studies in haploinsufficient mice will be successful, or that the FDA will not require further testing in these or other animal models. There is also no guarantee that the FDA will not reverse its interpretation of the results from past studies, such as those mentioned above.

As an organization, we have limited experience designing and no experience implementing clinical trials, and we have never conducted pivotal clinical trials. Failure to adequately design a trial, or incorrect assumptions about the design of the trial, could adversely affect the ability to initiate the trial, enroll patients, complete the trial, or obtain regulatory approval on the basis of the trial results, as well as lead to increased or unexpected costs.

The design and implementation of clinical trials is a complex process. While the employees who will implement our clinical trials may have experience in the field, we, as an organization, have limited experience designing and no experience implementing clinical trials, and we may not successfully or cost-effectively design and implement clinical trials that achieve our desired clinical endpoints efficiently, or at all. A clinical trial that is not well designed may delay or even prevent initiation of the trial, can lead to increased difficulty in enrolling patients, may make it more difficult to obtain regulatory approval for the product candidate on the basis of the study results, or, even if a product candidate is approved, could make it more difficult to commercialize the product successfully or obtain reimbursement from third-party payors. Additionally, a trial that is not well-designed could be inefficient or more expensive than it otherwise would have been, or we may incorrectly estimate the costs to implement the clinical trial, which could lead to a shortfall in funding. We also are required to register certain clinical trials and post the results of certain completed clinical trials on a government-sponsored database, www.clinicaltrials.gov, within specified timeframes. Failure to do so can result in enforcement actions and adverse publicity.

Interim, topline, or preliminary data from clinical trials that we announce or publish from time to time may change as more patient data becomes available or as we make changes to our manufacturing processes and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose interim, topline, or preliminary data from our preclinical studies and 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. We also make assumptions, estimations, calculations, and conclusions as part of our analyses of interim, topline or preliminary data, and therefore we may not have received or had the opportunity to fully and carefully evaluate all data. Further, modifications or improvements to our manufacturing processes for a therapy may result in changes to the characteristics or behavior of the product candidates that could cause our product candidates to perform differently and affect the results of our ongoing clinical trials. As a result, the topline 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. Topline 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. As a result, topline data should be viewed with caution until the final data are available.

Preliminary or interim data from clinical trials are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Adverse differences between preliminary or interim data and

33

final data could significantly harm our business prospects. Additionally, disclosure of preliminary or interim data by us or by our competitors could result in volatility in the price of our Common Stock.

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 program, the approvability or commercialization of the particular product candidate, and our company in general. If the interim, topline, or preliminary data that we report differs from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, any of our potential product candidates may be harmed, which could harm our business, operating results, prospects, or financial condition.

Even if we submit an IND to commence clinical trials for our lead product candidate, REN-001, or any of our other product candidates, the FDA may not allow testing and clinical trials to commence, or once commenced, there can be no guarantee that issues will not arise that delay, suspend or terminate such clinical trials.

We anticipate submitting an IND submission in connection with REN-001 in the second half of 2022, and expect our preclinical research pipeline to yield potential additional follow-on IND opportunities in cardiovascular and central nervous system ("CNS") diseases beyond that of our lead indication for BAG3 DCM. We cannot be sure that submission of an IND will result in the FDA allowing testing and clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate such clinical trials. The manufacturing of our product candidates remains an emerging and evolving field. Accordingly, we expect chemistry, manufacturing and control related topics, including product specifications, will be a focus of IND reviews, which may delay the clearance of INDs. Additionally, even if the FDA agrees with the design and implementation of the clinical trials set forth in an IND or clinical trial application, we cannot guarantee that the FDA will not change their requirements in the future.

We intend to study our product candidates in patient populations with significant comorbidities that may result in deaths or serious adverse events or unacceptable side effects and require us to abandon or limit our clinical development activities.

Patients we intend to treat with our product candidates may also receive angiotensin converting enzyme ("ACE") inhibitors, angiotensin receptor blockers, neprilysin inhibitors, SGLT2 inhibitors, beta-adrenergic receptor antagonists, aldosterone antagonists and/or diuretics or other medical and surgical interventions in the course of treatment of their disease, and they may therefore experience side effects or adverse events, including death, that are unrelated to our product candidates. While these side effects or adverse events may be unrelated to our product candidates, they may still affect the timeline and ultimate success of our clinical studies. The inclusion of patients that could become critically ill during our clinical studies may result in deaths or other adverse medical events due to underlying disease or to other therapies or medications that these patients may receive. Any of these events could prevent us from advancing our product candidates through clinical development and from obtaining regulatory approval, which would impair our ability to commercialize our product candidates. Any inability to advance our existing product candidates or any other product candidate through clinical development would have a material adverse effect on our business.

We may experience difficulties identifying and enrolling patients in our clinical trials, which could delay or prevent clinical trials of our lead product candidate, REN-001, or our other product candidates.

Identifying and qualifying patients to participate in clinical trials of REN-001 is critical to our success. The timing of our clinical trials depends in part on the speed at which we can recruit patients to participate in testing REN-001, and we may experience delays in our clinical trials if we encounter difficulties in enrollment. The eligibility criteria of our clinical trials may limit the pool of available study participants as we will require patients to have specific characteristics that we can measure to assure their disease is either severe enough or not too advanced to include them in a clinical trial. The process of finding and diagnosing patients may prove costly. We also may not be able to identify, recruit, and enroll a sufficient number of appropriate patients to complete our clinical trials because of demographic criteria for prospective patients, the perceived risks and benefits of the product candidate under study, the proximity and availability of clinical trial sites for prospective patients, and the patient referral practices of physicians. The availability and efficacy of competing therapies and clinical trials can also adversely impact enrollment. If patients are unwilling to participate in our trials for any reason, the timeline for recruiting patients, conducting trials, and obtaining regulatory approval of potential products may be delayed, the commercial prospects of REN-001 or our other product candidates will be harmed, and our ability to generate product revenue from any of these product candidates could be delayed or prevented. Furthermore, our inability to enroll a sufficient number of patients for our clinical trials could result in significant delays or may require us to abandon one or more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs and jeopardize our ability to achieve our clinical development timeline and goals, including the dates by which we will commence, complete and receive results from clinical trials. Enrollment delays in our clinical trials may also jeopardize our ability to commence sales of and generate revenues from REN-001 or our other product candidates. Any of these occurrences may harm our business, financial condition, and prospects significantly.

34

REN-001 and our other product candidates may cause adverse events or undesirable side effects that could delay or prevent our regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

While we believe our therapeutic BAG3 gene construct is non-immunogenic and do not expect the BAG3 gene or protein to elicit a significant immune response, gene therapy is still a relatively new approach to disease treatment and adverse side effects could develop. There also is the potential risk of delayed adverse events following exposure to gene therapy products due to persistent biologic activity of the genetic material or other components of products used to carry the genetic material including adverse side effects related to the AAV vector.

We are collecting data about REN-001 and our other product candidates in preclinical studies and will continue to do so in clinical trials, if and when they begin. To date, we have only evaluated our product candidate in preclinical animal models, and we, therefore, do not know the side effect profile of our product candidates in humans. Accordingly, we may experience unexpected side effects and/or higher levels of known side effects in clinical trials, including adverse events known in gene therapies. These include the potential for, among others, infusion reaction, vector/transgene-specific toxicities and disease-/host-specific idiosyncrasy and in rare cases certain cancers.

Any adverse events or undesirable side effects caused by, or other unexpected properties of, REN-001 or our other product candidates could cause us, any future collaborators, an IRB or ethics committee or regulatory authorities to interrupt, delay or halt clinical trials of our product candidate and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities. It is possible that as we progress REN-001 or our other product candidates through preclinical and clinical development, or as the use of REN-001 or our other product candidates become more widespread if we receive regulatory approval, illnesses, injuries, discomforts and other adverse events that were not observed in preclinical studies or clinical trials, as well as conditions that did not occur or went undetected, will be reported by patients. If such side effects become known later in development or after approval, such findings may harm our business, financial condition, and prospects significantly. Further, if a serious safety issue is identified in connection with the use of REN-001 or our other product candidates commercially or in third-party clinical trials elsewhere, such issues may adversely affect the development potential of REN-001 or our other product candidates or result in regulatory authorities restricting our ability to develop or commercialize REN-001 or our other product candidates.

Further, if REN-001 or any of our other product candidates were to receive regulatory approval and we or others identify undesirable side effects caused by the product (or any other product) after the approval, a number of potentially significant negative consequences could result, including:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercializing our product candidates and significantly impact our ability to successfully commercialize our product candidates and generate revenues, all of which would materially adversely affect our business, financial condition, and results of operations.

Public opinion and scrutiny of gene-based therapies for the treatment of human disease may impact public perception of us and our product candidates, or impair our ability to conduct our business.

Our lead product candidate, REN-001, is an AAV9 vector-based gene therapy designed to deliver a human BAG3 gene to express a fully functional human BAG3 protein in transduced cells for the treatment of BAG DCM. To date, there are no FDA-approved therapeutic interventions designed to address specific genetic mutations that result in heart failure. Public perception may be influenced by claims, such as claims that gene-based therapies are unsafe, unethical, or immoral. Accordingly, our approach may not

35

gain the acceptance of the public or the medical community. Negative public reaction to gene-based therapy in general could result in greater government regulation and stricter labeling requirements of gene-based therapeutic products, including any of our product candidates, and could cause a decrease in the demand for any products we may develop. Adverse public attitudes may adversely impact our ability to enroll clinical trials. More restrictive government regulations or negative public opinion could have an adverse effect on our business or financial condition and may delay or impair the development and commercialization of our product candidates or demand for any products we may develop.

If we do not meet our projected development goals on the timelines we announce and expect to meet, the potential approval of our products may be delayed.

From time to time, we estimate the timing of the accomplishment of various scientific, clinical, regulatory, manufacturing and other product development goals, which we sometimes refer to as milestones. These milestones may include the commencement or completion of preclinical studies and clinical trials and the submission of regulatory filings, including IND submissions. From time to time, we may publicly announce the expected timing of some of these milestones. The achievement of all of these milestones are, and will be, based on a variety of assumptions. The actual timing for achieving these milestones can vary significantly compared to our estimates, in some cases for reasons beyond our control. We may experience numerous unforeseen events during, or as a result of, any future clinical trials that we conduct that could delay or prevent our ability to receive marketing approval or commercialize our product candidates.

We rely, and expect to continue to rely, on third parties to conduct, supervise, and monitor our preclinical studies, and we will rely on third parties to conduct, supervise, and monitor future clinical trials for our product candidates.

We rely on third-party CROs, study sites, and others to conduct, supervise, and monitor our preclinical studies for our product candidates and we expect to rely on third parties to similarly conduct, supervise, and monitor any future clinical trials for our product candidates. We expect to continue to rely on third parties, such as CROs, clinical data management organizations, medical institutions, and clinical investigators, to conduct our preclinical studies, and intend to rely on third parties in connection with the commencement of future clinical trials of our product candidates. Although we have and will continue to have agreements with these third parties governing their activities, we have limited influence over their actual performance and will control only certain aspects of their activities. The failure of these third parties to successfully carry out their contractual duties or meet expected deadlines, including as a result of the impact of the coronavirus pandemic, could substantially harm our business because we may be delayed in completing or unable to complete the studies required to support future approval of REN-001 and our other product candidates, or we may not obtain marketing approval for, or commercialize, REN-001 and our other product candidates in a timely manner or at all. Moreover, these agreements might terminate for a variety of reasons, including a failure to perform by the third parties. If we need to enter into alternative arrangements our product development activities would be delayed and our business, financial condition, results of operations and prospects may be materially harmed.

Our reliance on these third parties for development activities reduces our control over these activities. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, regulatory, and scientific standards and our reliance on third parties does not relieve us of our regulatory responsibilities. For example, we will remain responsible for ensuring that each of our preclinical studies and future clinical trials is conducted in accordance with the general investigational plan and protocols for such trial. We must also ensure that our preclinical and future clinical trials are conducted in accordance with cGLP regulations, as appropriate. Moreover, the FDA and comparable foreign regulatory authorities require us to comply with cGCPs for conducting, recording, and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity, and confidentiality of trial participants are protected. Regulatory authorities enforce these requirements through periodic inspections of trial sponsors, clinical investigators, and trial sites. If we or any of our third parties fail to comply with applicable cGCPs or other regulatory requirements, we or such third parties may be subject to enforcement or other legal actions, the data generated in our preclinical studies and future clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional studies.

We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials will comply with the applicable regulatory requirements. In addition, our clinical trials must be conducted with product candidates that were produced under cGMP regulations. Failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process.

If any of our relationships with these third parties terminate, we may not be able to enter into arrangements with alternative providers or to do so on commercially reasonable terms. Switching or adding additional third parties involves additional cost and requires management’s time and focus. In addition, there is a natural transition period when a new third party commences work. As a result, delays could occur, which could compromise our ability to meet our desired development timelines.

36

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on research programs, therapeutic platforms, and product candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other therapeutic platforms or product candidates or for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs, therapeutic platforms, and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing, or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights.

Changes in regulatory requirements, guidance from the FDA and other regulatory authorities or unanticipated events during our preclinical studies and clinical trials of REN-001 or our other product candidates may result in changes to preclinical studies or clinical trials or additional preclinical or clinical trial requirements, which could result in increased costs to us and could delay our development timeline.

Regulatory requirements governing biologic drug products, including gene therapy products, are still evolving and it is difficult to determine how long it will take or how much it will cost to obtain regulatory approvals for REN-001 or our other product candidates. Changes in regulatory requirements, FDA guidance or guidance from other regulatory agencies or unanticipated events during our preclinical studies or clinical trials may force us to terminate or adjust our development program.

In addition, the clinical trial requirements of the FDA and foreign regulatory authorities and the criteria these regulators use to determine the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty and intended use and market of such product candidates. The regulatory approval process for novel product candidates such as ours can be more expensive and take longer than for other, better known or more extensively studied product candidates. The FDA, or the applicable regulatory authorities, may impose additional preclinical or clinical trial requirements. Amendments to clinical trial protocols would require resubmission to the FDA, or the applicable regulatory authorities as well as IRBs and ethics committees for review and approval, which may adversely impact the cost, timing or successful completion of a clinical trial. If we experience delays completing, or if we terminate, any of our clinical trials, or if we are required to conduct additional preclinical or clinical trials, the commercial prospects for REN-001 or our other product candidates may be harmed and our ability to generate product revenue will be delayed, and it would materially adversely affect our business, financial condition, and results of operations.

In order to market any product outside of the United States, we must comply with numerous and varying regulatory requirements of other countries regarding biologic development and commercialization. The approval process varies from country to country and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may negatively impact the regulatory process in others.

We are subject to various foreign, federal, and state healthcare and privacy laws and regulations, and our failure to comply with these laws and regulations could harm our results of operations and financial condition.

Our business operations and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors, and customers expose us to broadly applicable foreign, federal and state fraud and abuse and other healthcare and privacy laws and regulations. These laws may constrain the business or financial arrangements and relationships through which we conduct our operations, including how we research, market, sell and distribute any products for which we obtain marketing approval. Such laws include:

37

Ensuring that our internal operations and business arrangements with third-parties comply with applicable healthcare laws and regulations involve substantial costs. It is possible that governmental authorities will conclude that our business practices, including any consulting and advisory board arrangements with physicians and other healthcare providers, do not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the laws described above or any other governmental laws and regulations that may apply, we may be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from U.S. government funded healthcare programs, such as Medicare and Medicaid, or similar programs in other countries or jurisdictions, disgorgement, individual imprisonment, contractual damages, reputational harm, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, diminished profits and the curtailment or restructuring of our operations. Further, defending against any such actions can

38

be costly, time-consuming and may require significant financial and personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. If any of the physicians or other providers or entities with whom we expect to do business are found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusion from government funded healthcare programs and imprisonment. If any of the above occur, it could adversely affect our ability to operate our business and our results of operations.

Healthcare legislation, including potentially unfavorable pricing regulations or other healthcare reform initiatives, may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates.

The commercial potential for our approved products, if any, could be affected by changes in healthcare spending and policy in the United States and abroad. We operate in a highly regulated industry. New laws, regulations or judicial decisions or new interpretations of existing laws, regulations or decisions, related to healthcare availability, the method of delivery or payment for healthcare products and services could adversely affect our business, operations and financial condition. The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the healthcare system that may affect our ability to profitably sell our product and product candidates, if approved. The United States government, state legislatures and foreign governments also have shown significant interest in implementing cost-containment programs to limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement and requirements for substitution of generic products for branded prescription drugs and biologics.

The ACA was intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. There have been significant ongoing administrative, executive and legislative efforts to modify or eliminate the ACA. For example, the Tax Act enacted on December 22, 2017, repealed the shared responsibility payment for individuals who fail to maintain minimum essential coverage under Section 5000A of the IRC, commonly referred to as the individual mandate. The Trump administration issued executive orders which sought to reduce burdens associated with the ACA and modified how it was implemented. Other legislative changes have been proposed and adopted since passage of the ACA. The ACA has also been subject to challenges in the courts. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. On December 18, 2019, the Fifth Circuit U.S. Court of Appeals held that the individual mandate is unconstitutional and remanded the case to the Texas District Court to reconsider its earlier invalidation of the entire ACA. An appeal was taken to the U.S. Supreme Court (the "Supreme Court"), which heard oral arguments in the case on November 10, 2020. On June 17, 2021, the Supreme Court upheld the ACA and dismissed the case.

Further changes to and under the ACA remain possible, although the Biden administration has signaled that it plans to build on the ACA and expand the number of people who are eligible for subsidies under it. President Biden indicated that he intends to use executive orders to undo changes to the ACA made by the Trump administration and would advocate for legislation to build on the ACA. It is unknown what form any such changes or any law proposed to replace the ACA would take, and how or whether it may affect our business in the future. We expect that changes to the ACA, the Medicare and Medicaid programs, changes allowing the federal government to directly negotiate drug and biologic prices and changes stemming from other healthcare reform measures, especially with regard to healthcare access, financing or other legislation in individual states, could have a material adverse effect on the healthcare industry.

The Budget Control Act of 2011 has resulted in reductions in spending on certain government programs, including aggregate reductions to Medicare payments to healthcare providers of up to 2.0% per fiscal year. These reductions have been extended until 2030 unless additional Congressional action is taken.

Any reduction in reimbursement from Medicare, Medicaid, or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain and maintain profitability of our product and product candidates, if approved.

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 or our collaborators are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or our collaborators are not able to maintain regulatory compliance, REN-001 or any future product candidates may lose any marketing approval that may have been obtained and we may not achieve or sustain profitability, which would materially adversely affect our business, financial condition and results of operations.

Risks Related to Manufacturing

The manufacture and distribution of our recombinant AAV-derived gene product candidates is complex and subject to a multitude of risks. These risks could substantially increase our costs, limit the clinical and commercial supply of our product candidates, and result in delays in our development or commercialization programs.

The manufacture and supply of REN-001 and our other product candidates based on the BAG3 gene and protein involve novel processes that are more complex than those required for most drugs and biologics and, accordingly, present significant challenges and are subject to multiple risks.

Our product candidates require processing steps that are more complex than those required for most small molecule drugs. These are complex biological processes which include transfection of the gene of interest into a viral vector, production of viral vector in a host cell line, purification and characterization of the vector gene product. Moreover, unlike small molecules, the physical and chemical properties of a biologic such as ours generally cannot be fully characterized. Accordingly, we will employ multiple analytical methods to control the manufacturing process to assure that the process works consistently and the product candidate is made strictly and consistently in compliance with current regulatory expectations. Problems with the manufacturing process, even minor deviations from the normal process, could result in product defects or manufacturing failures that result in lot failures, low lot yields, product recalls, product liability claims or insufficient inventory. As a result, we may encounter problems achieving adequate quantities and quality of clinical-grade materials that meet the FDA or other applicable standards or specifications with consistent and acceptable production yields and costs. Accordingly, we expect chemistry, manufacturing and control of related topics, including product release specifications, will be a focus of IND reviews, which may delay the clearance of INDs.

In addition, the FDA and other regulatory authorities may require us to submit samples of any lot of any approved product together with the protocols showing the results of applicable tests at any time. Under some circumstances, the FDA or other regulatory authorities may require that we not distribute a lot until the agency authorizes its release. Slight deviations in the manufacturing process, including those affecting quality attributes and stability, may result in unacceptable changes in the product that could result in lot failures, low lot yields or product recalls. Lot failures, low lot yields or product recalls could cause us to delay product launches or clinical trials, which could be costly to and otherwise harm our business, financial condition, results of operations and prospects.

As a result of the complexities in manufacturing biologics and distributing gene therapies, the cost to manufacture and distribute biologics and gene therapies in general, and our gene product candidates in particular, is generally higher than traditional small molecule chemical compounds. In addition, our cost of goods development is at an early stage. The actual cost to manufacture and process our product candidates could be greater than we expect and could materially and adversely affect the commercial viability of REN-001 and our other product candidates.

We currently rely on and expect to continue to rely on third parties for the manufacture of our product candidates for development and such reliance may adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and competitive basis.

We currently do not operate manufacturing facilities and rely, and will continue to rely, on CDMOs for the manufacture of our product candidates and related raw materials for clinical and preclinical development and expect to rely on third parties for commercial manufacture if any of our product candidates receive marketing approval. We have partnered with CDMOs for the manufacture and supply of certain of our product candidates for future clinical development, but we may partner with other third party manufacturers for supplies in future clinical development. We have not yet secured manufacturing capabilities for commercial quantities of our product candidates. The competition for gene therapy contract development, manufacturing and testing is intense and we may be unable to negotiate binding agreements with the manufacturers to support our potential commercialization activities at commercially reasonable terms. Further, even with contractual agreements in place for the production and supply of our product candidates and related raw materials for our future clinical development, there can be no assurance the CDMOs or the manufacturing facilities will meet our demands on schedule or at all.

The facilities that may in the future be used by us, third-party CDMOs or any other manufacturers with which we may collaborate must be approved by the FDA pursuant to inspections that will be conducted after we submit a BLA to the FDA. For manufacturing facilities in which we do not operate, we do not control the manufacturing process of, and are completely dependent on, CDMOs for compliance with cGMP requirements for manufacture of biologic products. If these CDMOs cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities. In addition, we have no control over the ability of CDMOs to maintain adequate quality control and quality assurance. The CDMOs may also encounter problems hiring and retaining the experienced scientific, quality-control and manufacturing personnel needed to operate the required manufacturing processes, which could result in delays in production or difficulties in maintaining compliance with applicable regulatory requirements. If the FDA or a comparable

40

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 regulatory approval for or market our product candidates, if approved. Our failure, or the failure of our CDMOs, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, seizures or recalls of product candidates or products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates.

Our CDMO’s failure to execute on manufacturing requirements, to do so on commercially reasonable terms and comply with cGMP could adversely affect our business in a number of ways, including:

Any performance failure on the part of us or our existing or future CDMOs could delay clinical development or marketing approval, and any related remedial measures may be costly or time consuming to implement. If our current CDMOs cannot perform as agreed, we may be required to replace such manufacturers and we may be unable to replace them on a timely basis, with attractive terms or at all.

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

Changes in methods of product candidate manufacturing or formulation may result in additional costs or delay.

As product candidates proceed through preclinical studies to late-stage clinical trials towards potential approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize processes and results. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product candidates to perform differently and affect the results of planned preclinical studies or future clinical trials conducted with the materials manufactured using altered processes. Such changes may also require additional testing, FDA notification or FDA approval. This could delay completion of preclinical studies and clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase costs, delay approval of our product candidates and jeopardize our ability to commence sales and generate revenue.

CDMOs and suppliers use biological materials and may use hazardous materials, and any claims relating to improper handling, storage or disposal of these materials could be time consuming or costly.

Our CDMOs and suppliers may use hazardous materials, including potent chemicals and biological agents and compounds that could be dangerous to human health and safety or the environment. The operations of our CDMOs and suppliers also produce hazardous waste products. Federal, state and local laws and regulations govern the use, generation, manufacture, storage, handling and disposal of these materials and wastes. Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair our product development efforts. In addition, we cannot entirely eliminate the risk of accidental injury or contamination from these materials or wastes. We do not carry specific biological or hazardous waste insurance coverage, and our property, casualty and general liability insurance policies specifically exclude coverage for damages and fines arising from biological or hazardous waste exposure or contamination. 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.

41

Any contamination in our CDMO process, shortages of raw materials, labor or reagents or failure of any of our key suppliers to deliver necessary components of our platform could result in delays in our clinical development or marketing schedules.

Given the nature of biologics manufacturing, there is a risk of contamination. Any contamination could materially adversely affect our or our third-party vendor’s ability to produce our gene therapies on schedule and could therefore harm our results of operations and cause reputational damage.

The raw materials required in our third-party vendor’s manufacturing processes are derived from biological sources. We cannot be assured that our third-party vendors have, or will be able to obtain on commercially reasonable terms, or at all, sufficient rights to these materials derived from biological sources. Such raw materials are difficult to procure, may be difficult to substitute and may also be subject to contamination or recall. Further, COVID-19 has impacted supply chains globally, and my make it difficult for our third-party vendors to procure necessary materials in the future. A material shortage, contamination, recall, or restriction on the use of biologically derived substances in the manufacture of our product candidates could adversely impact or disrupt the clinical trials and commercial manufacturing of our product candidates, which could materially and adversely affect our operating results and development timelines.

We rely and will continue to rely on third-party suppliers for the supply and manufacture of certain components of our technology. We currently rely on a limited number of CDMOs as our suppliers of our preclinical and clinical materials for REN-001 and our other product candidates. Even if we were able to source REN-001 or our other product candidates from alternative suppliers or produce them by ourselves, such alternatives may cost more, result in lower yields or not be as suitable for our purposes. Should our ability to procure these material components from our suppliers be compromised, our ability to continuously operate would be impaired until an alternative supplier is sourced, qualified and tested, which could limit our ability to produce a clinical and commercial supply of our product candidates and harm our business.

Risks Related to Commercialization of Our Product Candidates

If we are unable to successfully commercialize REN-001 or any of our other product candidates for which we receive regulatory approval, or experience significant delays in doing so, our business will be materially harmed.

If we are successful in obtaining marketing approval from applicable regulatory authorities for REN-001 or any of our other product candidates, our ability to generate revenues from such product candidates will depend on our success in:

To the extent we are not able to do any of the foregoing, our business, financial condition, results of operations and prospects will be materially harmed.

42

We face significant competition, and if our competitors develop product candidates more rapidly than we do or their product candidates are more effective, our ability to develop and successfully commercialize products may be adversely affected.

The biopharmaceutical and pharmaceutical industries are characterized by rapid innovation, intense and dynamic competition and a strong emphasis on proprietary and novel products and product candidates. While we believe that our technology, scientific knowledge and foundational understanding in the field of BAG3 mutations provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biopharmaceutical companies, academic institutions and governmental agencies and public and private research institutions, as well as standard-of-care treatments, new products undergoing development and combinations of existing and new therapies. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies, including combinations thereof, that may become available in the future. We compete with these organizations to recruit management, scientists and clinical development personnel, which could negatively affect our level of expertise and our ability to execute our business plan. We will also face competition in establishing clinical trial sites, enrolling subjects for clinical trials and in identifying and in-licensing new product candidates. Smaller or early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies.

We are developing a pipeline of BAG3-based therapies for diseases of high unmet medical need associated with BAG3 biology. While we believe our proposed therapeutic intervention for BAG3 DCM derived from our AAV/BAG3 gene therapy product is significantly differentiated, a number of companies are currently focused on drug development and other therapies for the treatment of heart failure. Our principal competitors in the field of cardiomyopathy include, but are not limited to, Bayer AG, BioMarin Pharmaceutical, BridgeBio, Bristol-Myers Squibb Company, Cytokinetics, DiNAQOR AG, Ionis Pharmaceuticals, Sardocor Corp., Skyline Therapeutics, Tenaya Therapeutics and Takeda Pharmaceutical Company Limited. We are also aware of several companies developing gene therapies targeting heart failure, however, to the best our knowledge, none of these competitors’ programs are aimed directly at increasing BAG3 expression and we are not aware of any formally disclosed programs actively under development for BAG3 DCM. Nevertheless, these companies may compete with us in recruiting human capital and securing licenses to complementary technologies that may be critical to the success of our business. They also compete with us for potential funding from the biotechnology and pharmaceutical industries. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. Additionally, there may be other companies pursuing therapeutic candidates from which we face current or future competition.

Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we successfully obtain approval for any product candidate, we will face competition based on many different factors, including the safety and effectiveness of our products, the ease with which our products can be administered and the extent to which patients accept relatively new routes of administration, the timing and scope of regulatory approvals for these products, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position. Competing products could present superior treatment alternatives, including by being more effective, safer, more convenient, less expensive or marketed and sold more effectively than any products we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for our, which could result in our competitors establishing a strong market position before we are able to enter the market. Competitive products may make any products we develop obsolete or noncompetitive before we recover the expense of developing and commercializing our product candidates. If we are unable to compete effectively, our opportunity to generate revenue from the sale of the products we may develop, if approved, could be adversely affected.

We expect to face uncertainty regarding the pricing of our existing product candidates and any other product candidates that we may develop.

Due to the novel nature of our product candidates, we face significant uncertainty as to the pricing of any such products for which we may receive marketing approval. While we anticipate that pricing for any product candidates that we develop will be relatively high due to their anticipated use in the prevention or treatment of life-threatening diseases where therapeutic options are limited, the biopharmaceutical industry has recently experienced significant pricing pressures. In particular, drug pricing and other healthcare costs continue to be subject to intense political and societal pressures, which we anticipate will continue and escalate on a global basis. These pressures may result in harm to our business and reputation, cause our stock price to decline or experience periods of volatility and adversely affect results of operations and our ability to raise funds.

43

The insurance coverage and reimbursement status of newly-approved products is uncertain. Failure to obtain or maintain adequate coverage and reimbursement for new products could limit our product revenues.

Our ability to commercialize our lead product candidate, REN-001, or any of our other product candidates successfully will depend in part on the extent to which reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers, and other organizations. In the United States, the principal decisions about reimbursement for new therapies are typically made by Centers for Medicare and Medicaid Services, an agency within the U.S. Department of Health and Human Services ("CMS"). CMS decides whether and to what extent a new therapy will be covered and reimbursed under Medicare, and private payors tend to follow CMS determinations to a substantial degree. The availability and extent of reimbursement by governmental and private payors is essential for most patients to be able to afford expensive treatments, such as gene therapy. There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products by government and third-party payors. In particular, there is no body of established practices and precedents for reimbursement of gene therapy, and it is difficult to predict what the regulatory authority or private payor will decide with respect to reimbursement levels for novel products such as ours. Our products may not qualify for coverage or direct reimbursement, or may be subject to limited reimbursement. If reimbursement or insurance coverage is not available, or is available only to limited levels, we may not be able to successfully commercialize our product candidates. Even if coverage is provided, the approved reimbursement amount may not be sufficient to allow us to establish or maintain pricing to generate income.

In addition, reimbursement agencies in foreign jurisdictions may be more conservative than those in the United States. Accordingly, in markets outside the United States, the reimbursement for our products may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenues and profits. Moreover, increasing efforts by governmental and third-party payors, in the United States and abroad, to cap or reduce healthcare costs may cause such organizations to limit both coverage and level of reimbursement for new products approved and, as a result, they may not cover or provide adequate payment for our product candidates. Failure to obtain or maintain adequate reimbursement for any products for which we receive marketing approval will adversely affect our ability to achieve commercial success, and could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products, and our overall financial condition.

Even if we obtain regulatory and marketing approval for a product candidate, our product candidates will remain subject to regulatory oversight and we may be subject to penalties and other penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our product candidates.

Even if we receive marketing and regulatory approval for REN-001 or any of our other product candidates, regulatory authorities may still impose significant restrictions on the indicated uses or marketing or impose ongoing requirements for potentially costly post-approval studies. REN-001 and our other product candidates will also be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping and submission of safety and other post-market information. The FDA has significant post-market authority, including, for example, the authority to require labeling changes based on new safety information and to require post-market studies or clinical trials to evaluate serious safety risks related to the use of a biologic. Any regulatory approvals that we receive for REN-001 or our other product candidates may also be subject to a risk evaluation and mitigation strategy ("REMS"), limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including post-approval clinical trials, and surveillance to monitor the quality, safety and efficacy of the product, all of which could lead to lower sales volume and revenue. For example, the holder of an approved BLA is obligated to monitor and report adverse events and any failure of a product to meet the specifications in the BLA. The holder of an approved BLA also must submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling or manufacturing process. Advertising and promotional materials must comply with FDA rules and are subject to FDA review, in addition to other potentially applicable federal and state laws.

In addition, product manufacturers and their facilities are subject to payment of user fees and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP requirements and adherence to commitments made in the BLA or foreign marketing application. If we, or a regulatory authority, 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 that product, a regulatory authority may impose restrictions relative to that product, the manufacturing facility or us, including requiring recall or withdrawal of the product from the market or suspension of manufacturing.

If we or our contractors fail to comply with applicable regulatory requirements following approval of REN-001 or our other product candidates, a regulatory authority may:

44

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize REN-001 or our other product candidates and adversely affect our business, financial condition, results of operations, and prospects.

Even if we receive marketing approval for REN-001 or our other product candidates, we may not achieve broad market acceptance.

The commercial success of our lead product candidate, REN-001, or our other product candidates, if developed and approved for marketing by the FDA or comparable foreign regulatory authority, will depend upon the awareness and acceptance of REN-001 or such other product candidate among the medical community, including physicians, patients, advocacy groups and healthcare payors. Market acceptance of our product candidates, if approved, will depend on a number of factors, including, among others:

If REN-001 or any of our other product candidates are approved but do not achieve an adequate level of acceptance by patients, advocacy groups, physicians and payors, we may not generate sufficient revenue to become or remain profitable and our business, financial condition, and results of operations could be materially adversely affected. Our efforts to educate the medical community and third-party payors about the benefits of REN-001 and our other product candidates may require significant resources and may never be successful.

Even if we receive marketing approval for REN-001 or our other product candidates in the United States, we may never receive regulatory approval to market REN-001 or our other product candidates outside of the United States.

In order to market any product outside of the United States, we must establish and comply with the numerous and varying safety, efficacy and other regulatory requirements of other jurisdictions, including potential additional clinical trials and/or preclinical studies. Approval procedures vary among jurisdictions and can involve additional testing and additional administrative review periods. The

45

time required to obtain approvals in other jurisdictions might differ from that required to obtain FDA approval. The marketing approval processes in other jurisdictions may implicate all of the risks detailed above regarding FDA approval in the United States as well as other risks. In particular, in many jurisdictions outside of the United States, products must receive pricing and reimbursement approval before the product can be commercialized. Obtaining this approval can result in substantial delays in bringing products to market in such jurisdictions. Marketing approval in one jurisdiction does not necessarily ensure marketing approval in another, but a failure or delay in obtaining marketing approval in one country may have a negative effect on the regulatory process or commercial activities in others. Failure to obtain marketing approval in other jurisdictions or any delay or other setback in obtaining such approval would impair our ability to market a product candidate in such foreign markets. Any such impairment would reduce the size of our potential market, which could have a material adverse impact on our business, financial condition, results of operations, and prospects.

We may be unable to establish effective marketing, sales and distribution capabilities or enter into agreements with third parties to market and sell REN-001 or our other product candidates, if approved.

We currently do not have a commercial infrastructure for the marketing, sale, and distribution of our lead product candidate, REN-001, or our other product candidates. If REN-001 or our other product candidates receive marketing approval, we intend to commercialize such product candidates in the United States and potentially in other geographies. In order to commercialize our products, we must build our marketing, sales, and distribution capabilities or make arrangements with third parties to perform these services. We may not be successful in doing so. Should we decide to move forward in developing our own marketing capabilities, we may incur expenses prior to product launch or even approval in order to recruit a sales force and develop a marketing and sales infrastructure. If a commercial launch is delayed as a result of the FDA’s or comparable foreign regulatory authority’s requirements or for other reasons, we would incur these expenses prior to being able to realize any revenue from sales of REN-001 and our other product candidates. Even if we are able to effectively hire a sales force and develop a marketing and sales infrastructure, our sales force and marketing teams may not be successful in commercializing REN-001 or our other product candidates. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

We may also or alternatively decide to collaborate with third-party marketing and sales organizations to commercialize any approved product candidates in the United States, in which event, our ability to generate product revenues may be limited. To the extent we rely on third parties to commercialize any products for which we obtains regulatory approval, we may receive less revenues than if we commercialized these products ourselves, which could materially harm our prospects. In addition, we would have less control over the sales efforts of any other third parties involved in our commercialization efforts, and could be held liable if they failed to comply with applicable legal or regulatory requirements.

We have no prior experience in the marketing, sale, and distribution of biopharmaceutical products, and there are significant risks involved in building and managing a commercial infrastructure. The establishment and development of commercial capabilities, including compliance plans, to market any products we may develop will be expensive and time-consuming and could delay any product launch, and we may not be able to successfully develop this capability. We will have to compete with other biopharmaceutical and pharmaceutical companies to recruit, hire, train, manage, and retain marketing and sales personnel, which is expensive and time consuming and could delay any product launch. Developing our sales capabilities may also divert resources and management attention away from product development.

In the event we are unable to develop a marketing and sales infrastructure, we may not be able to commercialize REN-001 or our other product candidates in the United States or elsewhere, which could limit our ability to generate product revenues and materially harm our business, financial condition, results of operations and prospects.

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

The initial planned clinical trials for REN-001 are designed to evaluate its safety and tolerability in humans, as well as efficacy in the treatment of patients with BAG3 DCM. We do not know at this time whether REN-001 or any of our other product candidates will be safe for use in humans or produce efficacious results. Subsequently, we plan to conduct additional clinical trials in related indications, but there is no guarantee that product candidates we develop, even if approved for multiple related indications, would be approved for others, and, prior to any such approvals, we may have to conduct additional clinical trials.

We focus our research and product development on the use of AAV/BAG3-based gene therapy platforms for the treatment of a variety of different types of indications in heart failure and central nervous system diseases. Our projections of both the number of people who have BAG3 mutations, as well as the subset of people with these mutations who have the potential to benefit from treatment with our product candidates, are based on beliefs and estimates. These estimates have been derived from a variety of sources, including the scientific literature, surveys of clinics, patient foundations or market research, and may prove to be incorrect. Further, new trials may

46

change the estimated incidence or prevalence of such mutations. The total addressable market across all of our product candidates will ultimately depend upon, among other things, the diagnosis criteria included in the final label for each of our product candidates approved for sale for these indications, the availability of alternative treatments and the safety, convenience, cost and efficacy of our product candidates relative to such alternative treatments, acceptance by the medical community and patient access, drug and biologic pricing and reimbursement. The number of patients in the United States and other major markets and elsewhere may turn out to be lower than expected, patients may not be otherwise amenable to treatment with our products or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business.

Risks Related to Our Intellectual Property

If we are unable to protect our intellectual property and our proprietary technologies, we may not be able to compete effectively in the market.

Our commercial success depends in part on our ability to obtain and maintain patent protection and trade secret protection for REN-001 and any of our other product candidates, proprietary technologies and their uses as well as our ability to operate without infringing upon the proprietary rights of others. If we are unable to protect our intellectual property rights or if our intellectual property rights are inadequate for our technology or our product candidates, our competitive position could be harmed, which could have a material adverse impact on our business, results of operations, financial conditions and prospects. We generally seek to protect our proprietary position by filing patent applications in the United States and abroad related to REN-001 and any of our other product candidates, proprietary technologies and their uses that are important to our business. Our patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless, and until, patents are issued from such applications, and then only to the extent the issued claims cover the technology. There can be no assurance that our patent applications will result in patents being issued or that issued patents will afford sufficient protection to prevent competitors from using identical or similar technology, nor can there be any assurance that the patents if issued will be sufficiently broad or will not be infringed, designed around or invalidated by third parties. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. The degree of future protection for our proprietary rights is uncertain. Only limited protection may be available and may not adequately protect our rights or permit us to gain or keep any competitive advantage. These uncertainties and/or limitations in our ability to properly protect the intellectual property rights relating to REN-001 and any of our other product candidates could have a material adverse effect on our financial condition and results of operations.

Although we license an issued patent in Europe and license or jointly own pending patent applications in the United States and foreign countries, we cannot be certain that the claims in these U.S. pending patent applications, corresponding international patent applications and patent applications in certain foreign countries will be considered patentable by the United States Patent and Trademark Office (the "USPTO"), courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that the claims in our issued patent will not be found invalid or unenforceable if challenged.

The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or any of our potential future collaborators will be successful in protecting REN-001 and any of our other product candidates by obtaining and defending patents. These risks and uncertainties include the following:

47

The patent prosecution process is also expensive and time consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner or in all jurisdictions where protection may be commercially advantageous. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. Moreover, in some circumstances, we do not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, directed to technology that we license from third parties. We may also require the cooperation of our licensor in order to enforce the licensed patent rights, and such cooperation may not be provided. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. We cannot be certain that patent prosecution and maintenance activities by our licensors have been or will be conducted in compliance with applicable laws and regulations, which may affect the validity and enforceability of such patents or any patents that may issue from such applications. If they fail to do so, this could cause us to lose rights in any applicable intellectual property that we in-license, and as a result our ability to develop and commercialize products or product candidates may be adversely affected and we may be unable to prevent competitors from making, using and selling competing products.

In addition, although we enter into non-disclosure and confidentiality agreements with parties who have access to patentable aspects of our research and development output, such as our employees, outside scientific collaborators, CROs, third-party manufacturers, consultants, advisors and other third parties, any of these parties may breach such agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection.

We rely on licenses of intellectual property from Temple and may license intellectual property from other third parties in the future, and such licenses may not provide adequate rights or may not be available in the future on commercially reasonable terms, if at all, and our licensors may be unable to obtain and maintain patent protection for the technology or products that they license to us.

We have acquired rights to the intellectual property underlying REN-001 through the license agreement (the "Temple License Agreement"), dated August 12, 2019, with Temple University of the Commonwealth System of Higher Education ("Temple"), and may in the future enter into other license agreements with third parties for other intellectual property rights or assets. We are heavily reliant on licenses to the patent rights and proprietary technology from Temple provided to us under the License Agreement, and these licenses are necessary to the development of our technology and products, including the technology related to REN-001. These and other licenses may not provide adequate rights to use such technology in all relevant fields of use. Licenses to additional third-party technology that may be required for our development programs may not be available in the future or may not be available on commercially reasonable terms, which could have a material adverse effect on our business.

In some circumstances, we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, covering technology that we license from Temple and other third parties in the future. In addition, some of our agreements with our licensors require obtaining consent from the licensor before we can enforce patent rights and the licensor may withhold such consent or may not provide it on a timely basis. Thus, we cannot be certain that these patents and applications will be prosecuted and enforced in a manner consistent with the best interests of our business. In addition, if third parties from whom we license patents fail to maintain such patents, or lose rights to those patents, the rights we have licensed may be reduced or eliminated.

If we fail to comply with our obligations in the License Agreement under which we license intellectual property and other rights from Temple or otherwise experiences disruptions to our business relationships with Temple, we could lose license rights that are important to our business.

Our commercial success will depend in part on the maintenance of our license agreements. We have acquired rights to the intellectual property underlying REN-001 through the License Agreement with Temple, and may in the future enter into other license agreements with third parties for other intellectual property rights or assets. The License Agreement imposes, and future license agreements may impose, various diligence, milestone payment, royalty, and other obligations on us. If we fail to comply with our obligations under the License Agreement or any future license agreements with any party, or are subject to a bankruptcy, the licensor may have the right to terminate the license, in which event we would not be able to market products covered by the license. The License Agreement further provides Temple with a right to terminate the License Agreement for our material breach or default under the agreement, including the failure to make any required milestone or other payments. Should Temple exercise such a termination right, we would lose our right to the intellectual property under the License Agreement, and such loss may materially harm our business.

We may need to obtain licenses from third parties to advance our research or allow commercialization of REN-001 and any of our other product candidates, and we cannot provide any assurances that third-party patents do not exist which might be enforced against REN-001 and any of our other product candidates in the absence of such a license. We may fail to obtain any of these licenses on commercially reasonable terms, if at all, which could have a material adverse effect on our business and financial condition. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies. In that event,

48

we may be required to expend significant time and resources to develop or license replacement technology. If we are unable to do so, 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. Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues. Disputes may arise between us and our licensors regarding intellectual property subject to a license agreement, including:

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may not be able to successfully develop and commercialize the affected product candidates, which would have a material adverse effect on our business.

In addition, certain of our agreements may limit or delay our ability to consummate certain transactions, may impact the value of those transactions, or may limit our ability to pursue certain activities. For example, if we choose to sublicense or assign to any third parties our rights under our existing license agreements with respect to any licensed product, we may be required to pay a specified percentage of all revenue to be received in connection with such transaction.

We may need to obtain a license from REGENXBIO Inc. to develop and commercialize REN-001 and any of our other product candidates, and we cannot provide any assurances that we will be able to obtain such license.

We are aware of patents issued to REGENXBIO Inc. that claim AAV vectors that have an AAV9 capsid serotype. As such, we may need to obtain a license from REGENXBIO Inc. to develop and commercialize REN-001 and any of our other product candidates utilizing the AAV9 capsid serotype. If we commercialize any of our product candidates utilizing the AAV9 capsid serotype prior to the expiry of those patents in January 2026 without a license, it is possible that REGENXBIO Inc. could bring an action claiming infringement. If we fail to obtain a license from REGENXBIO Inc. on commercially reasonable terms, or at all, this could have a material adverse effect on our business and financial condition. Even if we are able to obtain such a license, it may be non-exclusive, thereby giving our competitors access to the same technologies or intellectual property rights licensed to us. In the event that we fail to obtain a license from REGENXBIO Inc., we may be required to expend significant time and resources to develop or license replacement technology which may be impossible or require substantial time and monetary expenditure. If we are unable to do so, we may be unable to develop and commercialize the affected product candidates, including our lead product candidate REN-001, which could materially harm our business and if we fail to obtain a license, REGENXBIO Inc. 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 which could limit our ability to generate revenue or achieve profitability. A finding of infringement could prevent us from commercializing our lead product candidate REN-001, which could harm our business, possibly prevent us from generating revenue sufficient to sustain our operations and force us to cease some of our business operations. In addition, under certain circumstances, we could be held liable for substantial monetary damages, potentially including enhanced damages and attorney fees if we are found to have willfully infringed the patent. Given our current expectation of submitting our first IND with respect to our lead product candidate REN-001 in the second half of 2022, and the anticipated timing of our expected approval pathway for our lead product candidate with the FDA, we expect that it will be at least several years, if ever, and in any event beyond January 2026, before we are able to commercialize our lead product candidate, and thus the need for a license from REGENXBIO Inc. with respect to commercialization of REN-001 is expected to be remote.

49

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 developing and commercializing similar or identical 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 applications may not result in patents being issued which protect our product candidates or which effectively prevent others from commercializing competitive 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. Even if patent applications we license or own currently or in the future issue as patents, they may not issue 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 that we license or own may be challenged or circumvented by third parties or may be narrowed or invalidated as a result of challenges by third parties. Consequently, we do not know whether REN-001 and any of our other product candidates 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 not cover REN-001 and any of our other product candidates or 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 USPTO, or become involved in opposition, derivation, revocation, reexamination, post-grant review ("PGR"), and inter partes review ("IPR"), or other similar proceedings in the USPTO or foreign patent offices challenging our patent rights. 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 or our predecessors and the patent examiner were unaware during prosecution. There is no assurance that all potentially relevant prior art relating to our patents and patent applications or those of our licensors has been found. There is also no assurance that there is not prior art of which we, our predecessors or licensors are aware, but which we do not believe affects the validity or enforceability of a claim in our patents and patent applications or those of our licensors, which may, nonetheless, ultimately be found to affect the validity or enforceability of a claim. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate or render unenforceable, our patent rights, allow third parties to commercialize REN-001 and any of our other product candidates and compete directly with us, without payment to us. Such loss of patent rights, loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable 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 REN-001 and any of our other product candidates. Such proceedings also may result in substantial costs and require significant time from our scientists and management, even if the eventual outcome is favorable to us. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

The patent protection and patent prosecution for some of our product candidates may be dependent on third parties and the failure to appropriately prosecute and maintain patent protection for patents covering REN-001 and any of our other product candidates, may adversely impact our ability to develop and commercialize those product candidates.

We or our licensors may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If we or our licensors, whether current or future, fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business.

As a licensee of third parties, we rely on third parties to file and prosecute patent applications and maintain patents and otherwise protect the licensed intellectual property under some of our license agreements. We have not had and do not have primary control over these activities for certain of our patents or patent applications and other intellectual property rights. We cannot be certain that such activities by third parties have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents or other intellectual property rights. Pursuant to the terms of the license agreements with some of our licensors, the licensors may have the right to control enforcement of these licensed patents or defense of any claims asserting the invalidity of these patents. Even if we are permitted to pursue such enforcement or defense, it will require the cooperation of our licensors. We cannot be

50

certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent us from continuing to license intellectual property that we may need to operate our business. If any of our licensors or any of our future licensors or future collaborators fail to appropriately prosecute and maintain patent protection for patents covering REN-001 and any of our other product candidates, our ability to develop and commercialize those product candidates may be adversely affected and we may not be able 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 acquired or licensed from third parties, we may still be adversely affected or prejudiced by actions or inactions of our predecessors or licensors and their counsel that took place prior to us assuming control over patent prosecution.

Our technology acquired or licensed from various third parties may be subject to retained rights. Our predecessors or licensors often retain certain rights under their agreements with us, including the right to use the underlying technology for noncommercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our predecessors or licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.

If we are limited in our ability to utilize acquired or licensed technologies, or if we lose our rights to critical in-licensed technology, we may be unable to successfully develop, out-license, market and sell our products, which could prevent or delay new product introductions. Our business strategy depends on the successful development of licensed and acquired technologies into commercial products. Therefore, any limitations on our ability to utilize these technologies may impair our ability to develop, out-license or market and sell REN-001 and any of our other product candidates.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

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 could significantly harm our business, results of operations and prospects.

51

Our success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties. Claims by third parties that we infringe their proprietary rights may result in liability for damages or prevent or delay our development and commercialization efforts.

Our success depends in part on avoiding infringement of the patents and proprietary rights of third parties. However, our research, development and commercialization activities may be subject to claims that they infringe or otherwise violate patents or other intellectual property rights owned or controlled by third parties. Other entities may have or obtain patents or proprietary rights that could limit or prevent our ability to make, use, sell, offer for sale or import REN-001 or any of our other product candidates that may be approved in the future, or impair our competitive position. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biopharmaceutical industry, including patent infringement lawsuits, oppositions, reexaminations, IPR proceedings and PGR proceedings before the USPTO and/or foreign patent offices. Numerous third-party U.S. and foreign issued patents and pending patent applications exist in the fields in which we are developing product candidates. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of REN-001 and any of our other product candidates.

As the biopharmaceutical industry expands and more patents are issued, the risk increases that REN-001 and any of our other product candidates may be subject to claims of infringement of the patent rights of third parties. Because patent applications are maintained as confidential for a certain period of time, until the relevant application is published we may be unaware of third-party patents that may be infringed by commercialization of REN-001 and any of our other product candidates, and we cannot be certain that we were the first to file a patent application related to REN-001 and any of our other product candidates. Moreover, because patent applications can take many years to issue, there may be currently-pending patent applications that may later result in issued patents that REN-001 and any of our other product candidates may infringe. In addition, identification of third-party patent rights that may be relevant to our technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. Furthermore, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. Any claims of patent infringement asserted by third parties would be time consuming and could:

Although no third party has asserted a claim of patent infringement against us as of the date of this Annual Report on Form 10-K, others may hold proprietary rights that could prevent REN-001 and any of our other product candidates from being marketed. Any patent-related legal action against us claiming damages and seeking to enjoin activities relating to REN-001 and any of our other product candidates or processes could, if successful, subject us to liability for damages, including treble damages if we were determined to willfully infringe, and require us to obtain a license to manufacture or develop REN-001 and any of our other product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. We cannot predict whether we would prevail in any such actions or that any license required under any of these patents would be made available on commercially acceptable terms, if at all. Moreover, even if we or our future strategic partners were able to obtain a license, the rights may be nonexclusive, which could result in our competitors gaining access to the same intellectual property. In addition, we cannot be certain that we could redesign REN-001 and any of our other product candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure to obtain necessary licenses, could prevent us from developing, manufacturing and commercializing REN-001 and any of our other product candidates, which could harm our business, financial condition and operating results.

Parties making claims against us may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or administrative proceedings, there is a risk that some of our confidential information could be compromised by disclosure. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a

52

material adverse effect on our ability to raise additional funds or otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time consuming and unsuccessful. Further, any of our issued patents could be found invalid or unenforceable if challenged in court.

Competitors may infringe our intellectual property rights or those of our licensors. To prevent infringement or unauthorized use, we and/or our licensors may be required to file infringement claims, which can be expensive and time consuming. In addition, in a patent infringement proceeding, a court may decide that a patent we own or license is not valid, is unenforceable and/or is not infringed. If we or any of our licensors or potential future collaborators were to initiate legal proceedings against a third party to enforce a patent directed at REN-001 or any of our other product candidates, the defendant could counterclaim that our patent is invalid and/or unenforceable in whole or in part. In patent litigation, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge include an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, written description or non-enablement. Grounds for an unenforceability assertion could include an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution.

If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on such product candidate. In addition, if the breadth or strength of protection provided by our patents and patent applications or those of our licensors is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates. Such a loss of patent protection would have a material adverse impact on our business. In September 2021, an opposition was filed against our European patent for BAG3 as a target of heart failure. We responded in January 2022 rebutting all grounds of the opponent’s opposition. There can be no assurance such opposition will not succeed.

Even if resolved in our favor, litigation or other legal proceedings relating to our intellectual property rights may cause us to incur significant expenses, and could distract our technical and management personnel from their normal responsibilities. 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. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our ability to compete in the marketplace.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or other legal proceedings relating to our intellectual property rights, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation or other proceedings.

Intellectual property litigation may lead to unfavorable publicity that harms our reputation and causes the market price of our Common Stock to decline.

During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as results of hearings, rulings on motions, and other interim proceedings in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our existing products, programs or intellectual property could be diminished. Accordingly, the market price of shares of our Common Stock may decline. Such announcements could also harm our reputation or the market for our future products, which could have a material adverse effect on our business.

Derivation or interference proceedings may be necessary to determine priority of inventions, and an unfavorable outcome may require us to cease using the related technology or to attempt to license rights from the prevailing party.

Derivation or interference proceedings provoked by third parties or brought by us or declared by the USPTO or similar proceedings in foreign patent offices may be necessary to determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Our defense of such proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. In addition, the uncertainties associated with such proceedings could have a material adverse effect on our ability to raise the funds necessary to continue our clinical trials, continue our research programs, license necessary technology from third parties or enter into development or manufacturing partnerships that would help us bring REN-001 and any of our other product candidates to market.

53

Changes in U.S. patent law, or laws in other countries, could diminish the value of patents in general, thereby impairing our ability to protect REN-001 and any of our other product candidates.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involve a high degree of technological and legal complexity. Therefore, obtaining and enforcing biopharmaceutical patents is costly, time consuming and inherently uncertain. Changes in either the patent laws or in the interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property and may increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. We cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. In addition, the U.S. Congress or other foreign legislative bodies may pass patent reform legislation that is unfavorable to us.

For example, the Supreme Court has ruled on several patent cases, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the U.S. federal courts, the USPTO, or similar authorities in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents we might obtain in the future.

The patent positions of companies engaged in the development and commercialization of biopharmaceuticals is particularly uncertain. Two significant cases involving diagnostic method claims and “gene patents” were decided by the Supreme Court. On March 20, 2012, the Supreme Court issued a decision in Mayo Collaborative Services v. Prometheus Laboratories, Inc. ("Prometheus"), a case involving patent claims directed to a process of measuring a metabolic product in a patient to optimize a drug dosage for the patient. According to the Supreme Court, the addition of well-understood, routine or conventional activity such as “administering” or “determining” steps was not enough to transform an otherwise patent-ineligible natural phenomenon into patent-eligible subject matter. On June 13, 2013, the Supreme Court issued its decision in Association for Molecular Pathology v. Myriad Genetics, Inc. ("Myriad"), a case involving patent claims held by Myriad relating to the breast cancer susceptibility genes BRCA1 and BRCA2. Myriad held that an isolated segment of naturally occurring DNA, such as the DNA constituting the BRCA1 and BRCA2 genes, is not patent- eligible subject matter, but that complementary DNA, which is an artificial construct that may be created from RNA transcripts of genes, may be patent-eligible.

The USPTO has issued a number of guidance memorandum and updates to USPTO patent examiners on the ramifications of the Prometheus, Myriad and other court rulings in the application of the rulings to natural products and principles including all naturally occurring nucleic acids. USPTO guidance may be further updated in view of developments in the case law and in response to public feedback. Patents for certain of our product candidates contain claims related to specific DNA sequences that are naturally occurring and, therefore, could be the subject of future challenges made by third parties. In addition, USPTO guidance or changes in guidance or procedures issued by the USPTO could make it impossible for us to pursue similar patent claims in patent applications it may prosecute in the future.

We cannot assure that our efforts to seek patent protection for our technology and products will not be negatively impacted by the decisions described above, rulings in other cases or changes in guidance or procedures issued by the USPTO. We cannot fully predict what impact the Supreme Court’s decisions in Prometheus and Myriad may have on the ability of life science companies to obtain or enforce patents relating to their products and technologies in the future. These decisions, the guidance issued by the USPTO and rulings in other cases or changes in USPTO guidance or procedures could materially harm our existing patent portfolio and our ability to protect and enforce our intellectual property in the future.

Moreover, although the Supreme Court has held in Myriad that isolated segments of naturally occurring DNA are not patent-eligible subject matter, certain third parties could allege that activities that we may undertake infringe other gene-related patent claims, and we may determine it is necessary to defend ourselves against these claims by asserting noninfringement and/or invalidity positions, or paying to obtain a license to these patents. In any of the foregoing or in other situations involving third-party intellectual property rights, if we are unsuccessful in defending against claims of patent infringement, we could be forced to pay damages or be subjected to an injunction that would prevent us from utilizing the patented subject matter. Such outcomes could harm our business, financial condition, results of operations or prospects.

54

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property which could result in substantial costs.

We may also be subject to claims that former employees or other third parties are inventors of, or have an ownership interest in, our patents or other intellectual property. For example, we are aware of a complaint filed against Temple by an individual alleging a claim to inventorship and ownership rights to U.S. application 15/115.807 and ex-U.S. equivalents. While we believe the claims are without merit, litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and distraction to management and other employees.

Patent terms may be inadequate to protect our competitive position on REN-001 and any of our other product candidates for an adequate amount of time.

Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the term of a patent, and the protection it affords, is limited. Even if patents covering REN-001 and any of our other product candidates are obtained, once the patent 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 product candidates, patents protecting REN-001 and any of our other product candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

If we do not obtain patent term extension for REN-001 or any of our other product candidates, our business may be materially harmed.

Depending upon the timing, duration and specifics of FDA marketing approval of REN-001 and any of our other product candidates, one or more of our U.S. patents may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984 (the "Hatch Waxman Act"). The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. A maximum of one patent may be extended per FDA approved product as compensation for the 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 and only those claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. Patent term extension may also be available in certain foreign countries upon regulatory approval of our product candidates. However, we may not be granted an extension 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. In addition, we may be reliant on third party licensors and collaborators in applying for such patent term extensions and we may not be able to obtain their cooperation. If we are unable to obtain patent term extension or restoration or the term of any such extension is less than we request, our competitors may obtain approval of competing products following our patent expiration, and our revenue could be reduced, possibly materially. Further, if this occurs, our competitors may take advantage of our investment in development and trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case.

We may not be able to protect our intellectual property rights throughout the world, which could diminish the value of the intellectual property and lead to impairment of our competitive position.

Although we have patents and pending patent applications in the United States and certain other countries, filing, prosecuting and defending patents in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States or from selling or importing products made using our inventions in the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop its 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 product candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

55

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of many foreign countries, particularly in certain foreign countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biotechnology patents, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights. Proceedings to enforce our patent 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 and 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 rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Many foreign 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 are 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.

Obtaining and maintaining our patent protection depends on compliance with various procedural, documentary, fee payment and other requirements imposed by regulations and governmental 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 governmental fees on patents and/or applications will be due to the USPTO and various foreign patent offices at various points over the lifetime of our patents and/or applications. We rely on third parties to pay these fees when due. Additionally, the USPTO and various foreign patent offices require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. We employ reputable law firms and other professionals to help us comply and are also dependent on our licensor to take the necessary action to comply with these requirements with respect to our licensed intellectual property. In many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with rules applicable to the particular jurisdiction. However, there are situations in which noncompliance can result in irreversible abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If such an event were to occur, potential competitors might be able to enter the market which could have a material adverse effect on our business.

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

In addition, we rely on the protection of our trade secrets, including unpatented know-how, technology and other proprietary information to maintain our competitive position. Although we have taken steps to protect our trade secrets and unpatented know-how, including entering into confidentiality agreements with third parties, and confidential information and inventions agreements with employees, consultants and advisors, we cannot provide any assurances that such agreements were obtained in all circumstances or that all have been duly executed, and any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets. We may not be able to obtain adequate remedies for such breaches, even if these agreements have been obtained.

Adequate remedies may not exist in the event of unauthorized use or disclosure of our confidential information, including a breach of our confidentiality agreements. 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.

Moreover, third parties may still obtain this technology or information or may come upon this or similar information independently, and we would have no right to prevent them from using that technology or information to compete with us. If any of these events occurs or if we otherwise lose protection for our trade secrets, the value of this information may be greatly reduced and our competitive position would be harmed. If we do not apply for patent protection prior to such publication or if we cannot otherwise maintain the confidentiality of our proprietary technology and other confidential information, then our ability to obtain patent protection or to protect our trade secret information may be jeopardized.

56

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.

We have two pending trademark applications with the USPTO for the mark “RENOVACOR” and the Renovacor logo, approval of which is not guaranteed. Once registered, our trademarks or trade names can be challenged, infringed, circumvented, declared generic or determined to be infringing on other marks. We may not be able to protect the 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 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 and unregistered trademarks or trade names. Over the long term, if we were 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 result in substantial costs and diversion of resources, which could adversely impact our financial condition.

We may be subject to claims that we have wrongfully hired an employee or consultant from a competitor or that we or our employees or consultants have wrongfully used or disclosed alleged confidential information or trade secrets of their former employers.

As is common in the biopharmaceutical industry, in addition to our employees, we engage the services of consultants to assist us in the development of REN-001 and our other product candidates. Some of these consultants or employees may have been employed at, or may have previously provided or may be currently providing, consulting services to other biopharmaceutical companies including our competitors or potential competitors. We may become subject to claims that we, our employees or a consultant inadvertently or otherwise used or disclosed trade secrets or other information proprietary to their former employers or their former or current clients. 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, which could adversely affect our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management team and other employees.

Risks Related to Employee Matters, Managing Growth and Other Risks Related to Our Business

We are dependent on the services of our management and other clinical and scientific personnel, and if we are not able to retain these individuals or recruit additional management or clinical and scientific personnel, our business will suffer.

Our success depends in part on our continued ability to attract, retain and motivate highly qualified management, clinical and scientific personnel, many of whom have been instrumental for us and have substantial experience with our BAG3-based platform, underlying technologies and related product candidates. Given the specialized nature of our BAG3-based platform and the fact that it is a novel field, there is an inherent scarcity of experienced personnel in this field. As we continue developing our product candidates in our pipeline, we will require personnel with medical, scientific, or technical qualifications specific to each program.

We are highly dependent upon Magdalene Cook, M.D., our President and Chief Executive Officer, Marc Semigran, M.D., our Chief Medical Officer, and Matthew Killeen, Ph.D., our Chief Scientific Officer, as well as our senior scientists and advisors. The loss of services of any of these individuals could delay or prevent the successful development of our product pipeline, initiation or completion of our planned preclinical studies and clinical trials or the commercialization of REN-001 and our other product candidates. We have executed an employment agreement with Dr. Cook, Dr. Semigran and Dr. Killeen, each of which is terminable at will with or without notice and, therefore, we may not be able to retain their services as expected. We do not currently maintain “key person” life insurance on the lives of our executives or any of our employees.

Our research and development programs, clinical operations and sales and marketing efforts depend on our ability to attract and retain highly skilled scientists, engineers and sales professionals. The competition for qualified personnel in the biotechnology and pharmaceutical industries is intense, and we have experienced, and expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications on acceptable terms, or at all. Many of the companies with which we compete for experienced personnel have greater resources than we do, and any of our employees may terminate their employment with us at any time. If we hire employees from competitors or other companies, their former employers may attempt to assert that we or these employees have breached legal obligations, resulting in a diversion of our time and resources and, potentially, damages. In addition, job candidates and existing employees often consider the value of the stock awards they receive in connection with their employment. If the perceived benefits of our stock awards decline, it may harm our ability to recruit and retain highly skilled employees. If we fail

57

to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects would be harmed.

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

As of March 15, 2022, we had 19 full-time employees and approximately 15 part-time consultants. As our development and commercialization plans and strategies develop, and as we continue to transition into operating as a public company, 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, our ability to advance REN-001 and our other product candidates will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities. In addition, we expect to incur additional costs in hiring, training and retaining such additional personnel.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize REN-001 and our other product candidates and, accordingly, may not achieve our research, development and commercialization goals.

If we fail to maintain proper and effective internal controls over financial reporting, our ability to produce accurate and timely financial statements could be impaired.

We are required to maintain internal controls over financial reporting. Commencing with our 2022 fiscal year, we must perform system and process design evaluation and testing of the effectiveness of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting in our Annual Report on Form 10-K for that year, as required by Section 404 of the Sarbanes-Oxley Act. This will require that we incur substantial additional professional fees and internal costs to expand our accounting and finance functions and expend significant management efforts. Prior to the Business Combination, we have never been required to test our internal controls within a specified period and, as a result, we may experience difficulty in meeting these reporting requirements in a timely manner. In addition, if we identify material weaknesses in our internal control over financial reporting in the future or otherwise fail to maintain an effective system of internal controls, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect our business.

If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, if our independent registered public accounting firm determines that we have a material weakness or a significant deficiency in our internal control over financial reporting, or we are unable to maintain proper and effective internal controls over financial reporting, we may not be able to produce timely and accurate financial statements. As a result, our investors could lose confidence in our reported financial information, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities.

We believe that any 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. We may discover weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Our internal control over financial reporting will not prevent or detect all errors and all fraud. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. For example, our directors or executive officers could inadvertently fail to disclose a new relationship or arrangement causing us to fail to make a required related party transaction disclosure. 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

58

controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and may not be detected.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.

Because we currently rely on other third parties to manufacture our product candidates and to perform certain quality testing, we must, at times, share our proprietary technology and confidential information, including trade secrets, with them. We seek to protect our proprietary technology, in part, by entering into confidentiality agreements, consulting agreements or other similar agreements with our advisors, employees and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are intentionally or inadvertently incorporated into the technology of others or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets and despite our efforts to protect our trade secrets, a competitor’s discovery of our proprietary technology and confidential information or other unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on our business, financial condition, results of operations and 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 are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing, and use of pharmaceutical products. While we currently have no product candidates that have commenced clinical trials or been approved for commercial sale, the future use of product candidates by us in clinical trials, and the sale of any approved products in the future, may expose us to liability claims. For example, we may be sued if REN-001 and our other product candidates allegedly cause injury or are found to be otherwise unsuitable during product testing, manufacturing, marketing or sale. 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 candidate, negligence, strict liability and a breach of warranties. Claims may be brought against us by clinical trial participants, patients or others using, administering or selling products that may be approved in the future. Claims could also be asserted under state consumer protection acts.

If we cannot successfully defend against product liability claims, we may incur substantial liabilities or be required to limit or cease the commercialization of our products. Even a successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

We currently hold approximately $4.0 million in general liability insurance coverage in the aggregate and hold a $1.0 million umbrella policy. We may need to increase our insurance coverage as we expand our clinical trials or if we commence commercialization of REN-001 or our other product candidates. Insurance coverage is increasingly expensive. Our inability to obtain and retain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the

59

commercialization of REN-001 or our other product candidates. Although we maintain such insurance, any claim that may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies will also 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.

We may be unable to adequately protect our information systems from cyberattacks, which could result in the disclosure of confidential or proprietary information, including personal data, damage our reputation, and subject us to significant financial and legal exposure.

We rely on information technology systems that we or our third-party providers operate to process, transmit and store electronic information in our day-to-day operations. In connection with our product discovery efforts, we may collect and use a variety of personal data, such as names, mailing addresses, email addresses, phone numbers and clinical trial information. Despite our implementation of security measures, our internal computer systems, and those of our CROs, CDMOs, information technology suppliers and other contractors and consultants are vulnerable to damage from computer viruses, cyberattacks and other unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical failures. A successful cyberattack could result in the theft or destruction of intellectual property, data, or other misappropriation of assets, or otherwise compromise our confidential or proprietary information and disrupt our operations. Cyberattacks are increasing in their frequency, sophistication and intensity, and have become increasingly difficult to detect. Cyberattacks could include wrongful conduct by hostile foreign governments, industrial espionage, wire fraud and other forms of cyber fraud, the deployment of harmful malware, denial-of-service, social engineering fraud or other means to threaten data security, confidentiality, integrity and availability. A successful cyberattack could cause serious negative consequences, including, without limitation, the disruption of operations, the misappropriation of confidential business information, including financial information, trade secrets, financial loss and the disclosure of corporate strategic plans. Although we devote resources to protect our information systems, we realize that cyberattacks are a threat, and there can be no assurance that our efforts will prevent information security breaches that would result in business, legal, financial or reputational harm to us, or would have a material adverse effect on our results of operations and financial condition. Any failure to prevent or mitigate security breaches or improper access to, use of, or disclosure of our clinical data or patients’ personal data could result in significant liability under state (e.g., state breach notification laws), federal (e.g., HIPAA, as amended by HITECH), and international law (e.g., the GDPR) and may cause a material adverse impact to our reputation, affect our ability to conduct new studies and potentially disrupt our business.

We rely on our third-party providers to implement effective security measures and identify and correct for any such failures, deficiencies or breaches. If we or our third-party providers fail to maintain or protect our information technology systems and data integrity effectively or fail to anticipate, plan for or manage significant disruptions to our information technology systems, we or our third-party providers could have difficulty preventing, detecting and controlling such cyberattacks and any such attacks could result in the losses described above as well as disputes with physicians, patients and our partners, regulatory sanctions or penalties, increases in operating expenses, expenses or lost revenues or other adverse consequences, any of which could have a material adverse effect on our business, results of operations, financial condition, prospects and cash flows. Any failure by such third parties to prevent or mitigate security breaches or improper access to or disclosure of such information could have similarly adverse consequences. If we are unable to prevent or mitigate the impact of such security or data privacy breaches, we could be exposed to litigation and governmental investigations, which could lead to a potential disruption to our business. By way of example, the CCPA, which went into effect on January 1, 2020, creates individual privacy rights for California consumers and increases the privacy and security obligations of entities handling certain personal data. 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. The CCPA may increase our compliance costs and potential liability, and many similar laws have been proposed at the federal level and in other states. By way of example regarding foreign laws and regulations with respect to data privacy and security, the GDPR went into effect in the EU in May 2018 and introduced strict requirements for processing the personal data of EU data subjects. Companies that must comply with the GDPR face increased compliance obligations and risk, including more robust regulatory enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or 4% of the annual global revenues of the noncompliant company, whichever is greater.

60

Our employees and independent contractors, including principal investigators, CROs, consultants and vendors, may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements that could result in us incurring significant penalties.

We are exposed to the risk that our employees and independent contractors, including principal investigators, CROs, consultants and vendors may engage in misconduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violate: the laws and regulations of the FDA and other similar regulatory requirements, including those laws that require the reporting of true, complete and accurate information to such authorities; manufacturing standards, including cGMP requirements; federal and state data privacy, security, fraud and abuse and other healthcare laws and regulations in the United States and abroad; or laws that require the true, complete and accurate reporting of financial information or data. Activities subject to these laws also involve the improper use or misrepresentation of information obtained in the course of clinical trials, the creation of fraudulent data in preclinical studies or clinical trials, or illegal misappropriation of drug or biologic product, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct by employees and other 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 or regulations. In addition, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending or asserting our rights, those actions could have a significant impact on our business and financial results, including, without limitation, the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgements, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, individual imprisonment, contractual damages, reputational harm, diminished profits and future earnings, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

Risks Related to Ownership of Our Securities

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will be influenced to some extent by the research and reports that industry or financial analysts publish about us and our business. We do not control these analysts. As a newly public company, we may be slow to attract research coverage and the analysts who publish information about our common stock will have had relatively little experience with us or our business and products, which could affect their ability to accurately forecast our results and could make it more likely that we fail to meet their estimates. In the event we obtain securities or industry analyst coverage, if any of the analysts who covers us provide inaccurate or unfavorable research or issue an adverse opinion regarding our stock price, our stock price could decline. If one or more of these analysts cease coverage of us or fail to publish reports covering us regularly, we could lose visibility in the market, which om turn could cause our stock price or trading volume to decline and result in the loss of all or a part of your investment in us.

If the Business Combination’s benefits do not meet the expectations of investors, stockholders or financial analysts, the market price of our securities may decline. Additionally, trading prices for our securities could be highly volatile, and purchasers of our securities could incur substantial losses.

If the benefits of the Business Combination do not meet the expectations of investors, stockholders or securities analysts, the market price of our securities may decline. The market values of our securities may vary significantly from their prices on the date of this Annual Report on Form 10-K.

In addition, fluctuations in the price of our securities could contribute to the loss of all or part of your investment. Immediately prior to the Business Combination, there was not a public market for stock relating to Old Renovacor’s business and trading in shares of our Common Stock has not been active. Accordingly, the valuation ascribed to our business and our Common Stock in the Business Combination may not be indicative of the price that will prevail in the trading market.

The trading price of our Common Stock may fluctuate substantially and may be lower than its current price. This may be especially true for companies like ours with a small public float. If an active market for our securities develops and continues, the trading price of our securities could be volatile and subject to wide fluctuations. The trading price of our Common Stock will depend on many factors, including those described in this “Risk Factors” section, many of which are beyond our control and may not be related to our operating performance. These fluctuations could cause you to lose all or part of your investment in our Common Stock since you might be unable to sell your shares at or above the price attributed to them in the Business Combination. Any of the factors listed

61

below could have a material adverse effect on your investment in our securities and our securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of our securities may not recover and may experience a further decline.

Factors affecting the trading price of our securities may include:

Broad market and industry factors may materially harm the market price of our securities irrespective of our operating performance. The stock market in general and the NYSE American LLC (the "NYSE") have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of our securities, may not be predictable. A loss of investor confidence in the market for the stocks of other companies which investors perceive to be similar to ours could depress our stock price regardless of our business, prospects, financial conditions or results of operations. Broad market and industry factors, including, most recently, the impact of the novel coronavirus, COVID-19, and any other global pandemics, as well as general economic, political and market conditions such as recessions or interest rate changes, may seriously affect the market price of our Common Stock, regardless of our actual operating performance. A decline in the market price of our securities also could adversely affect our ability to issue additional securities and our ability to obtain additional financing in the future.

62

In addition, in the past, following periods of volatility in the overall market and the market prices of particular companies’ securities, securities class action litigations have often been instituted against these companies. Litigation of this type, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources. Any adverse determination in any such litigation or any amounts paid to settle any such actual or threatened litigation could require that we make significant payments.

Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide.

Our quarterly and annual operating results may fluctuate significantly, which makes it difficult for us to predict our future operating results. These fluctuations may occur due to a variety of factors, many of which are outside of our control, including, but not limited to:

The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our future performance.

This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our Common Stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated revenue or earnings guidance we may provide.

Changes in laws, regulations or rules, or a failure to comply with any laws, regulations or rules, may adversely affect our business, investments and results of operations.

We are subject to laws, regulations and rules enacted by national, regional and local governments and the NYSE. In particular, we are required to comply with certain SEC, NYSE and other legal or regulatory requirements. Compliance with, and monitoring of, applicable laws, regulations and rules may be difficult, time consuming and costly. Those laws, regulations or rules and their interpretation and application may also change from time to time and those changes could have a material adverse effect on our business, investments and results of operations. In addition, a failure to comply with applicable laws, regulations or rules, as interpreted and applied, could have a material adverse effect on our business and results of operations.

63

Our second amended and restated certificate of incorporation designates specific courts as the exclusive forum for substantially all stockholder litigation matters, which could limit the ability of our stockholders to obtain a favorable forum for disputes with us or our directors, officers or employees.

Our second amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against current or former directors, officers or other employees for breach of fiduciary duty, any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law ("DGCL"), our second amended and restated certificate of incorporation or our amended and restated bylaws, any action asserting a claim governed by internal affairs doctrine of the State of Delaware or any other action asserting an “internal corporate claim” (as defined in Section 115 of the DGCL), confers jurisdiction to the Court of Chancery of the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware does not have subject matter jurisdiction thereof, any state court located in the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware), unless we consent in writing to the selection of an alternative forum. This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Our second amended and restated certificate of incorporation also provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. This provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us and our directors, officers or other employees and may have the effect of discouraging lawsuits against our directors, officers and other employees. Furthermore, stockholders may be subject to increased costs to bring these claims, and the exclusive forum provision could have the effect of discouraging claims or limiting investors’ ability to bring claims in a judicial forum that they find favorable.

In addition, the enforceability of similar exclusive forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with one or more actions or proceedings described above, a court could rule that this provision in our second amended and restated certificate of incorporation is inapplicable or unenforceable. In March 2020, the Delaware Supreme Court issued a decision in Salzburg et al. v. Sciabacucchi, which found that an exclusive forum provision providing for claims under the Securities Act to be brought in federal court is facially valid under Delaware law. We intend to enforce this provision, but we do not know whether courts in other jurisdictions will agree with this decision or enforce it. If a court were to find the exclusive forum provision contained in our second amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, prospects, financial condition and operating results.

Our second amended and restated certificate of incorporation could discourage another company from acquiring us and may prevent attempts by our stockholders to replace or remove our management.

Provisions in our second amended and restated certificate of incorporation and our amended and restated bylaws may discourage, delay or prevent, a merger, acquisition or other Change in Control (as defined in the Merger Agreement) of us that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our Common Stock, thereby depressing the market price of our Common Stock. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. As our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our stockholders to replace current members of our management team. These provisions provide, among other things, that:

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the DGCL, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Delaware law may delay or prevent a Change in Control, and may discourage bids for our Common Stock at a premium over its market price.

We are subject to the provisions of section 203 of the Delaware General Corporation Law. These provisions prohibit large stockholders, in particular a stockholder owning 15% or more of the outstanding voting stock, from consummating a merger or combination with a corporation unless this stockholder receives board approval for the transaction or 66 2/3% of the shares of voting stock not owned by the stockholder approve the merger or transaction. These provisions of Delaware law may have the effect of delaying, deferring or preventing a Change in Control, and may discourage bids for our Common Stock at a premium over its market price.

Risks Related to Accounting and Financial Reporting

We are currently an emerging growth company and a smaller reporting company within the meaning of the Securities Act, and to the extent we have taken advantage of certain exemptions from disclosure requirements available to emerging growth companies or smaller reporting companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are currently an “emerging growth company” within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, our stockholders may not have access to certain information they may deem important. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company, which is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

65

We will cease to be an emerging growth company upon the earliest of (i) December 31, 2025, or the end of the fiscal year following the fifth anniversary of the closing of the initial public offering of Chardan, which closed on April 28, 2020 (the "Chardan IPO"); (ii) the first fiscal year after our annual gross revenues are $1.07 billion or more; (iii) the date on which we have, during the three-year period, issued more than $1.0 billion in nonconvertible debt securities; or (iv) the end of any fiscal year in which we are deemed to be a large accelerated filer, which means the market value of our Common Stock held by non-affiliates exceeded $700 million as of the end of the second quarter of that fiscal year.

Additionally, we are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements.

We will remain a smaller reporting company until the last day of the fiscal year in which (1) the market value of our Common Stock held by non-affiliates exceeds $250 million as of the end of that fiscal year’s second fiscal quarter, or (2) our annual revenues exceeded $100 million during such completed fiscal year and the market value of our Common Stock held by non-affiliates exceeds $700 million as of the end of that fiscal year’s second fiscal quarter. To the extent we take advantage of such reduced disclosure obligations, it may also make comparison of our financial statements with other public companies difficult or impossible.

Once we lose our “emerging growth company” and/or “smaller reporting company” status, we will no longer be able to take advantage of certain exemptions from reporting, and we will also be required to comply with the auditor attestation requirements of section 404 of the Sarbanes-Oxley Act. We will incur additional expenses in connection with such compliance and our management will need to devote additional time and effort to implement and comply with such requirements.

Our Private Placement Warrants, Sponsor Earnout Shares, and Earnout Shares are currently accounted for as liabilities and the changes in value of our Private Placement Warrants, Sponsor Earnout Shares and Earnout Shares could have a material effect on our financial results.

On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the SEC together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”)” (the "SEC Statement"). Specifically, the SEC Statement focused on certain settlement terms and provisions related to certain tender offers following a business combination, which terms are similar to those contained in the Warrant Agreement, dated as of April 23, 2020, by and between Chardan and Continental Stock Transfer & Trust Company (the "Warrant Agreement"), governing Chardan’s warrants issued to the Sponsor in a private placement simultaneously with the closing of the Chardan IPO (the "Private Placement Warrants"). As a result of the SEC Statement, Chardan reevaluated the accounting treatment of the Private Placement Warrants and determined to classify the Private Placement Warrants as derivative liabilities measured at fair value, with changes in fair value each period reported in earnings. As a result, included on our balance sheet as of December 31, 2021 are derivative liabilities related to embedded features contained within the Private Placement Warrants. In addition, the Sponsor Earnout Shares and the Earnout Shares are accounted for as derivative liabilities, with changes in fair value each period reported in earnings. Accounting Standards Codification 815-40, Derivatives and Hedging — Contracts in Entity’s Own Equity (ASC 815), provides for the remeasurement of the fair value of such derivatives at each balance sheet date, with a resulting non-cash gain or loss related to the change in the fair value being recognized in earnings in the statement of operations. As a result of the recurring fair value measurement, our financial statements and results of operations may fluctuate quarterly, based on factors, which are outside of our control. Due to the recurring fair value measurement, we expect that we will recognize non-cash gains or losses on our Private Placement Warrants, Sponsor Earnout Shares and Earnout Shares each reporting period and that the amount of such gains or losses could be material.

Chardan identified a material weakness in its internal control over financial reporting. Although this material weakness was remediated, and we have since adopted the controls and procedures of Old Renovacor following closing of the Business Combination, those controls and procedures may not be adequate to prevent material weaknesses in the future.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Our management also evaluates the effectiveness of our internal controls and we will disclose any changes and material weaknesses identified through such evaluation in those internal controls. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or surrounding interim financial statements will not be prevented or detected on a timely basis.

66

Chardan implemented a remediation plan, described under Item 4, Controls and Procedures of our March 31, 2021 Quarterly Report on Form 10-Q filed with the SEC on May 25, 2021, to remediate the material weakness related to the historical presentation of the Private Placement Warrants but can give no assurance that the measures taken will prevent any future material weaknesses or deficiencies in internal control over financial reporting. Even though we have adopted the controls and procedures of Old Renovacor following closing of the Business Combination, in the future those controls and procedures may not be adequate to prevent or identify irregularities or errors or to facilitate the fair presentation of our financial statements.

We may face litigation and other risks as a result of the material weakness previously identified in Chardan's internal control over financial reporting prior to the closing of the Business Combination.

Following the issuance of the SEC Statement, Chardan’s management and audit committee concluded that it was appropriate to revise its previously issued financial statements as of and for the year ended December 31, 2020, as well as certain interim periods within 2020, on Form 10-Q filed with the SEC on May 25, 2021. See above under the heading “ —Our Private Placement Warrants, Sponsor Earnout Shares, and Earnout Shares are currently accounted for as liabilities and the changes in value of our Private Placement Warrants, Sponsor Earnout Shares and Earnout Shares could have a material effect on our financial results.” As part of the restatement, Chardan identified a material weakness in its internal controls over financial reporting.

As a result of such material weakness, the restatement, the change in accounting for the warrants and other matters raised or that may in the future be raised by the SEC, we face potential for litigation or other disputes which may include, among others, claims invoking the federal and state securities laws, contractual claims or other claims arising from the restatement and material weaknesses in Chardan's internal control over financial reporting and the preparation of our financial statements. As of the date of this Annual Report on Form 10-K, we have no knowledge of any such litigation or dispute. However, we can provide no assurance that such litigation or dispute will not arise in the future. Any such litigation or dispute, whether successful or not, could have a material adverse effect on our business, results of operations and financial condition and related transactions.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Until the consummation of the Business Combination, we maintained our executive offices at 17 State Street, 21st Floor, New York, NY 10004.

All preclinical lab operations to date have been conducted at the Feldman laboratory pursuant to the Temple SRA. We plan to establish principal executive offices and lab operations in Pennington, New Jersey, and Boston, Massachusetts.

Item 3. Legal Proceedings.

From time to time, we may become involved in various legal proceedings that arise in the ordinary course of our business. We are not currently a party to any material legal proceedings and are not aware of any pending or threatened legal proceeding against us that we believe could have an adverse effect on our business, operating results or financial condition.

Item 4. Mine Safety Disclosures.

None.

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

The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements and accompanying notes appearing elsewhere in this Annual Report on Form 10-K; and

In addition to historical information, this discussion and analysis includes forward-looking statements that are subject to risks and uncertainties, including those discussed in the section titled “Risk Factors,” set forth in Part I, Item 1A of this Annual Report on Form 10-K, that could cause actual results to differ materially from historical results or anticipated results.

Prior to September 2, 2021, we were known as Chardan Healthcare Acquisition 2 Corp. On September 2, 2021, we completed the Business Combination with Renovacor Holdings, Inc., a private company. For accounting purposes, Chardan Healthcare Acquisition 2 Corp. was deemed to be the acquired entity. Unless the context indicates otherwise, references in this section to the “Company,” “Renovacor,” “we,” “us,” “our” and similar terms refer to Renovacor, Inc. (f/k/a Chardan Healthcare Acquisition 2 Corp.) and our consolidated subsidiaries. References to “Chardan” refer to our predecessor company prior to the consummation of the Business Combination. References to “Old Renovacor” refer to Renovacor, Inc. prior to the consummation of the Business Combination and to Renovacor Holdings, Inc. (f/k/a Renovacor, Inc.), now the wholly owned subsidiary of Renovacor, upon the consummation of the Business Combination.

Overview

We are a biotechnology company focused on delivering innovative precision therapies to improve the lives of patients and families battling genetically-driven cardiovascular and mechanistically-related diseases. Our initial focus is on the treatment of BCL2-associated athanogene 3 (BAG3) mutation-associated dilated cardiomyopathy ("DCM") ("BAG3 DCM"). BAG3 DCM is a heritable rare disease that leads to early onset, rapidly progressing heart failure and significant mortality and morbidity. Our lead product candidate, REN-001, is a recombinant adeno-associated virus ("AAV") 9-based gene therapy designed to deliver a fully functional BAG3 gene to augment BAG3 protein levels in cardiomyocytes and slow or halt progression of BAG3 DCM.

We believe that development of a BAG3 gene replacement therapy for DCM patients who carry BAG3 gene mutations has the potential to prevent progression of DCM and heart failure. Diseases caused by monogenic defects are especially tractable targets for gene therapies. Recently approved therapies have successfully utilized AAV as a vehicle to deliver genes to patients suffering from these diseases and there are many additional ongoing clinical development programs utilizing AAV-based gene therapies to address monogenic diseases.

We believe we are the first company to apply AAV technology to patients with DCM specifically due to mutations in the BAG3 gene. REN-001 utilizes an AAV9 vector intended to deliver a healthy version of the BAG3 gene to produce functional BAG3 protein in patients with genetic mutations that cause insufficient levels of functional BAG3 protein. This approach has shown promise in multiple preclinical models, demonstrating production of functional BAG3 protein and improvement in cardiac function.

We anticipate submitting an Investigational New Drug ("IND") application in connection with our lead product candidate, REN-001, in the second half of 2022, and plan to initiate a phase I/II clinical trial of REN-001 in patients with BAG3 DCM following IND application acceptance by the U.S. Food and Drug Administration (“FDA”).

The Business Combination

On September 2, 2021, we consummated the previously announced business combination contemplated by that certain Agreement and Plan of Merger, dated March 22, 2021 (the “Merger Agreement”), by and among the Company, CHAQ2 Merger Sub, Inc., a wholly owned subsidiary of the Company (“Merger Sub”), and Renovacor Holdings, Inc. (f/k/a Renovacor, Inc. ("Old Renovacor")). Pursuant to the Merger Agreement, on September 2, 2021 (the "Closing Date"), Merger Sub merged with and into Old Renovacor, with Old Renovacor as the surviving company in the merger and, after giving effect to such merger, continuing as a wholly owned subsidiary of the Company (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Business Combination”). On the Closing Date, the Company changed its name from Chardan Healthcare Acquisition 2 Corp. to Renovacor, Inc.

The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Chardan was treated as the “acquired” company and Old Renovacor is treated as the acquirer for financial reporting purposes as more fully explained in Note 3 of the accompanying notes to the condensed consolidated financial statements contained elsewhere in this Annual Report on Form 10-K.

69

Prior to the Business Combination, we were a special purpose acquisition company, formed for the purpose of acquiring, through a merger, share exchange, asset acquisition, stock purchase, reorganization, recapitalization, or other similar business transaction, one or more operating businesses or entities, and prior to consummation of the Business Combination, our operating activities consisted of our formation, initial public offering and costs associated with the Business Combination. The intended strategy of the combined company will continue to focus on Old Renovacor’s core product/service offerings related to precision medicine treatments for genetically-driven cardiovascular and mechanistically-related diseases, as more fully described below.

On September 2, 2021, our common stock, par value $0.0001 per share ("Common Stock") and our warrants originally issued in our initial public offering, began trading on the NYSE American LLC ("NYSE") under the ticker symbols “RCOR” and “RCOR.WS,” respectively.

COVID-19

We continue to monitor the potential impact of the novel coronavirus disease ("COVID-19") pandemic, including variants thereof such as the delta and omicron variants, on our business and financial statements. To date, we have not experienced material business disruptions. We are following, and will continue to follow, recommendations from the U.S. Centers for Disease Control and Prevention as well as federal, state, and local governments regarding working-from-home practices for non-essential employees. For example, the COVID-19 outbreak in Pennsylvania resulted in a temporary reduction in workforce presence at the Temple research facility, including the Feldman laboratory, located in Philadelphia, at which we operate. While the Feldman laboratory is currently operating at normal capacity, we cannot be certain that the Temple facility or the Feldman laboratory will not be closed in the future, or experience labor shortages, as a result of the COVID-19 outbreak. Accordingly, the full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including expenses and manufacturing, preclinical and clinical trials and research and development costs, will depend on future developments that are highly uncertain at this time.

Results of Operations

Years Ended December 31, 2021 and 2020

Overview

During the year ended December 31, 2021, our loss from operations totaled $18.6 million, a 477% increase, compared to a loss from operations of $3.2 million for the year ended December 31, 2020. Research and development expenses comprise the majority of our total operating expenses, as shown in the table below.

Research and Development Expenses

Research and development expenses consist of costs incurred for our research activities, including our discovery efforts, and the development of our programs. These expenses include:

We expense research and development costs as incurred. Non-refundable advance payments that we make for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed, or when it is no longer expected that the goods will be delivered or the services rendered.

Our direct external research and development expenses consist of costs that include fees, reimbursed materials, and other costs paid to consultants, contractors, CDMOs and other research organizations in connection with our preclinical activities. We do not allocate employee costs, costs associated with our discovery efforts, laboratory supplies, facilities expenses, including depreciation or other indirect costs, to specific product development programs because these costs are deployed across multiple programs and, as such, are not separately classified.

71

In the table below, research and development expenses are set forth in the following categories: (i) compensation and related benefits and (ii) other external research and development costs.

Total research and development expenses were $11.8 million for the year ended December 31, 2021, a 385% increase compared to total research and development expenses of $2.4 million for the year ended December 31, 2020. The increase during year ended December 31, 2021, as compared to 2020, was primarily due to increases in (i) compensation-related costs associated with the hiring of key personnel, (ii) drug supply costs associated with our preclinical activities, including IND-enabling studies and preparation for potential clinical trials, and (iii) external costs associated with the execution of ongoing preclinical studies as we prepare for an IND submission for REN-001, which is anticipated in the second half of 2022, and related clinical activities.

Substantially all research and development expenses incurred by us to date relate to the discovery and preclinical development of REN-001.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and personnel-related costs, including stock-based compensation, for personnel in executive, finance and accounting, and other administrative functions. General and administrative expenses also include legal fees relating to patent and corporate matters; professional fees paid for accounting, auditing, consulting, and tax services; insurance costs and travel expenses.

Total general and administrative expenses were $6.9 million for the year ended December 31, 2021, a 754% increase compared to total general administrative expenses of $0.8 million for the year ended December 31, 2020. The increase during the 2021 period was primarily due to increases in (i) compensation-related costs associated with the hiring of key personnel, (ii) professional and consulting fees due to increases in patent-related legal costs and fees incurred with investor/public relations and financial advisory firms, (iii) merger-related costs, including legal and accounting fees, incurred in connection with the Business Combination which were allocated to warrant and share earnout liabilities, and (iv) other costs related to additional spending as a result of our growth and operating as a publicly-traded company.

Interest Expense

During the year ended December 31, 2021, we recorded interest expense of approximately $0.1 million representing interest paid and amortization of debt discounts (e.g., issuance costs and embedded derivative) related to our convertible note issued in July 2021, which was converted into shares of our common stock in September 2021 upon closing of the Business Combination.

Change in Fair Value of Derivative Liability

During the year ended December 31, 2021, we recorded a change in fair value of derivative liability, representing a non-cash derivative revaluation gain of approximately $0.1 million, related to the derecognition of the derivative liability associated with certain embedded features in the Note Purchase Agreement (as defined herein) which were required to be bifurcated and accounted for separately as derivative financial instrument, due to the conversion of the Convertible Promissory Note (as defined herein) upon closing of the Business Combination.

72

Change in Fair Value of Warrant Liability

During the year ended December 31, 2021, we recorded a change in the fair value of warrant liability, representing a non-cash warrant revaluation gain of approximately $2.2 million, related to our liability-classified Private Placement Warrants, as more fully described in Note 10 of the notes to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K. Due to the nature of and inputs in the model used to assess the fair value of our outstanding Private Placement Warrants, it is not abnormal to experience significant fluctuations during each remeasurement period. These fluctuations may be due to a variety of factors, including changes in our stock price and changes in estimated stock price volatility over the remaining life of the warrants. Changes in the fair value of the warrant liability and resulting warrant revaluation gain for the year ended December 31, 2021 was driven primarily by the decrease in our stock price as of December 31, 2021, compared to our stock price as of the September 2, 2021 issuance date.

Change in Fair Value of Share Earnout Liability

During the year ended December 31, 2021, we recorded a change in fair value of share earnout liability, representing a non-cash share earnout revaluation gain of approximately $2.4 million, related to our liability-classified Earnout Shares, as more fully described in Note 3 of the notes to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K. Due to the nature of and inputs in the model used to assess the fair value of the outstanding Earnout Shares, it is not abnormal to experience significant fluctuations during each remeasurement period. These fluctuations may be due to a variety of factors, including changes in our stock price and changes in estimated stock price volatility over the remaining life of the warrants. Changes in the fair value of the share earnout liability and resulting share earnout revaluation gain for the year ended December 31, 2021 was driven primarily by the decrease in our stock price as of December 31, 2021, compared to our stock price as of the September 2, 2021 issuance date.

Net Loss Applicable to Common Stockholders

As a result of the factors discussed above, our net loss applicable to common stockholders for the years ended December 31, 2021 and 2020 was $14.1 million and $3.2 million, respectively.

73

Financial Condition, Liquidity and Capital Resources

Financial Condition

As of December 31, 2021, we had an accumulated deficit of $19.0 million. To date, we have not generated any revenues.

Since our inception, we have focused substantially all of our resources on organizing and staffing the company, in-licensing key intellectual property, business planning, raising capital, conducting research and development activities, filing and prosecuting patent applications, and engaging in other preclinical activities. We do not have any products approved for sale and have not generated any revenue from product sales or from any other sources. To date, we have funded our operations with proceeds from the Business Combination and the PIPE Investment (as defined herein), sales of convertible preferred stock, and a convertible note. Since our inception, we have incurred significant operating losses. Our ability to generate any product revenue, and in particular to generate product revenue sufficient to achieve profitability, will depend on the successful development and eventual commercialization of one or more of our product candidates.

Liquidity and Capital Resources

Overview

We require cash to fund our operating expenses and to make capital expenditures. Historically, we have funded our cash requirements primarily through the sale of preferred stock, common stock, pre-funded warrants, common stock warrants and a convertible note. As of December 31, 2021 we had $78.8 million of cash.

Note Purchase Agreement

On July 20, 2021, in accordance with the Merger Agreement and pursuant to a note purchase agreement (the “Note Purchase Agreement”), dated July 20, 2021, by and between Old Renovacor and Chardan Healthcare Investments, LLC ("Chardan Healthcare"), an affiliate of our sponsor, Chardan Investments 2, LLC (the "Sponsor"), Old Renovacor issued a $2.5 million convertible promissory note to Chardan Healthcare (the “Convertible Promissory Note”) in exchange for $2.5 million in cash to be used to finance Old Renovacor’s operations through the consummation of the Merger. In connection with the consummation of the Merger, the total principal of $2.5 million converted automatically into shares of Common Stock, at a price per share equal to $10.00.

PIPE Investment (Private Placement)

Concurrently with the execution of the Merger Agreement, we entered into subscription agreements (the "Subscription Agreements"), with certain investors ("PIPE Investors"), including Chardan Healthcare, certain stockholders of Old Renovacor and certain other institutional and accredited investors, pursuant to which, on the Closing Date, and concurrently with the closing of the Business Combination, the PIPE Investors purchased an aggregate of 2,284,776 shares Common Stock, at a price of $10.00 per share, and a pre-funded warrant entitling the holder thereof to purchase 715,224 shares of Common Stock (the "Pre-Funded Warrant") at an initial purchase price of $9.99 per share underlying the Pre-Funded Warrant, for aggregate gross proceeds of approximately $30.0 million (the "PIPE Investment").

Funding Requirements

We believe that, based on our current operating plan, our existing cash on hand as of December 31, 2021 will enable us to fund our operations into the second half of 2023. Specifically, we believe our available funds will be sufficient to enable us to perform the following:

However, we have based this estimate on assumptions that may prove to be wrong, and our operating plan may change as a result of many factors currently unknown to us. In addition, we could utilize our available capital resources sooner than expected.

74

Our net losses were $14.1 million and $3.2 million for the years ended December 31, 2021 and 2020, respectively. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. We expect our expenses and capital expenditures to increase substantially in connection with our ongoing activities, particularly if and as we:

We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for one or more of our product candidates. If we obtain regulatory approval for any of our product candidates, we expect to incur significant expenses related to developing our commercialization capability to support product sales, marketing, and distribution. As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy.

Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. Additionally, we may receive up to an aggregate of approximately $89.8 million from the exercise of our warrants outstanding as of December 31, 2021, assuming the exercise in full of such warrants for cash. See Note 10 of the notes to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K for additional details on our outstanding warrants. However, certain warrants may be exercised on a cashless basis and our warrants may never be exercised. If we fail to raise capital or enter into such agreements or arrangements as, and when, needed, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more of our product candidates. The timing and amount of our funding requirements will depend on many factors, including:

75

In addition, increases in expenses or delays in clinical development may adversely impact our cash position and require additional funds or cost reductions.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, it will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and may be forced to reduce or terminate our operations, or relinquish rights to portions of our technology and/or product candidates.

Cash Flows

The following table provides a summary of the primary sources and uses of cash for the periods presented:

Operating Activities. The net cash used in operating activities for each period presented consists primarily of net loss adjusted for non-cash charges and changes in components of working capital. The increase in cash used in operating activities for the year ended December 31, 2021, as compared to 2020, was primarily due to significant increases in expenditures and corresponding cash outflows related to our REN-001 development program, including payments to consultants and contract research and manufacturing organizations, as we prepare for our potential clinical activities for REN-001.

Financing Activities. Net cash provided by financing activities primarily consisted of the following amounts received in connection with the following transactions:

Investing Activities. Net cash used in investing activities during the year ended December 31, 2021 was nominal and related to equipment purchases. There was no cash used in or provided by investing activities during the year ended December 31, 2020.

Contractual Obligations and Commitments

Temple License Agreement and SRA

In August 2019, we entered into both the Temple License Agreement and Temple SRA, as further discussed within Note 9 of the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Pursuant to the Temple License Agreement, we are responsible for all the ongoing costs relating to the prosecution and maintenance of the licensed Temple Patent Rights going forward. We also agreed to pay Temple a minimum annual administrative fee of $20,000 per year beginning with the effective date of the License Agreement and continuing each annual anniversary thereafter.

Additionally, the Temple License Agreement requires us to pay up to an aggregate of $1.25 million to Temple upon the achievement of certain developmental, regulatory and commercial milestones for the first licensed product that achieves said milestones regardless of the number of licensed products that achieve them. In addition, we are required to pay Temple a low single-digit royalty on net sales of any product utilizing the Temple Patent Rights, up to 50% of which may be reduced by payments we make to third parties for freedom to operate. In addition, we must also pay a percentage of all consideration based on a percentage of sublicense consideration received by it, which percentage ranges from the mid-teens to mid-twenties depending on the stage of development at the time of the sublicense agreement.

The Temple License Agreement will remain effective until (i) the expiration date of the last-to-expire patents covered under the Temple License Agreement (currently expected to occur in 2041), (ii) the termination by Temple upon (a) an uncured breach by us, with a 60-day notification period, (b) our filing of a voluntary petition in bankruptcy or related proceeding, provided such petition is not dismissed within 90 days after the filing thereof, (c) a failure by us to meet certain milestones set forth in the License Agreement, or (d) non-payment of undisputed monies due to Temple, with a 30-day notification period. Additionally, we may terminate the entire agreement or with respect to an individual patent or patent application, if desired, subject to a 90-day notification period.

As it relates to the Temple SRA, which was amended effective as of August 12, 2019, August 27, 2019 and July 1, 2021, Temple will conduct certain preclinical activities through June 2024, unless terminated sooner or extended by mutual written consent, for which we will be obligated to fund approximately $5.3 million through June 30, 2024, of which approximately $1.4 million has been funded and/or incurred since inception of the Temple SRA through December 31, 2021.

Other

We enter into contracts in the normal course of business with CDMOs, CROs, and other third parties for preclinical study activities. These contracts do not contain minimum purchase commitments and are cancelable by us upon prior written notice. Payments due upon cancellation consist only of payments for services provided or expenses incurred, including non- cancelable obligations of our service providers, up to the date of cancellation.

Critical Accounting Policies and Significant Judgments and Estimates

This management’s discussion and analysis of financial condition and results of operations is based on our audited consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and judgments which are affected by the application of our accounting policies

Management bases its estimates and judgments on historical experience and on various other factors that are believed to be appropriate under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

We regard an accounting estimate or assumption underlying our financial statements as a “critical accounting estimate” where:

While our significant accounting policies are described in more detail in Note 2 of the accompanying notes to the consolidated financial statements contained in this Annual Report on Form 10-K, not all of these significant policies, however, fit the definition of critical accounting policies and estimates. We believe the following accounting policies to be most critical to the judgments and estimates used in the preparation of our financial statements:

Research and Development Prepayments, Accruals and Related Expenses

As part of the process of preparing our financial statements, we are required to estimate our accrued and prepaid expenses for research and development activities performed by third parties, including CROs and clinical investigators. These estimates are made as of the reporting date of the work completed over the life of the individual study in accordance with agreements established with CROs and clinical trial sites. Some CROs invoice us on a monthly basis, while others invoice upon achievement of milestones and the expense is recorded as services are rendered. We determine the estimates of research and development activities incurred at the end of each reporting period through discussion with internal personnel and outside service providers as to the progress or stage of completion of trials or services, as of the end of each reporting period, pursuant to contracts with clinical trial centers and CROs and the agreed upon fee to be paid for such services. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. Clinical trial site costs related to patient enrollments are recorded as patients are entered into the trial.

Warrant Liabilities and Related Change in Fair Values (Gains / Losses)

We utilize a Black-Scholes model to value our outstanding Private Placement Warrants at each reporting period, with changes in fair value recognized in the consolidated statements of operations. The estimated fair value of the warrant liability is determined using Level 3 inputs. Inherent in an options pricing model are assumptions related to expected share-price volatility, expected life, risk-free interest rate and dividend yield. We estimate the expected volatility of our common stock based on historical volatility of a peer group, considering the expected remaining life of the Private Placement Warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the valuation date for a maturity similar to the expected remaining life of the Private Placement Warrants. The expected life of the Private Placement Warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which we anticipate to remain at zero. Due to the nature of and inputs in the model used to assess the fair value of the warrants, it is not abnormal to experience significant fluctuations during each remeasurement period.

Share Earnout Liabilities and Related Change in Fair Values (Gains / Losses)

We utilize a Monte Carlo simulation to value our outstanding Earnout Shares. We selected this model as we believe it is reflective of all significant assumptions that market participants would likely consider in negotiating the transfer of the Earnout Shares. Such assumptions include, among other inputs, expected stock price volatility, risk-free rates, and change in control assumptions. We estimate probability of a change in control based on both market data for the biotechnology industry and managements own assessment. We estimate the expected volatility of our common stock based on historical volatility of a peer group, considering the remaining term of the Earnout Shares. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the valuation date for a maturity similar to the expected remaining life of the Earnout Shares. The expected life of the Earnout Shares is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which we anticipate to

remain at zero. Due to the nature of and inputs in the model used to assess the fair value of the Earnout Shares, it is not abnormal to experience significant fluctuations during each remeasurement period.

Additionally, see Note 3 of the accompanying notes to the consolidated financial statements contained in this Annual Report on Form 10-K for information pertaining to accounting for the Business Combination.

New Accounting Pronouncements

New accounting pronouncements are discussed in Note 2 in the notes to the consolidated financial statements in this Annual Report on Form 10-K.

Emerging Growth Company Status

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that we (1) are no longer an emerging growth company, or (2) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

We will remain an emerging growth company until the earliest of (1) the last day of the fiscal year following the fifth anniversary of the closing of the initial public offering of Chardan, (2) the last day of the fiscal year in which we have total annual gross revenue of at least $1.07 billion, (3) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year, or (4) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

As of December 31, 2021, all material assets and liabilities are in U.S. dollars, which is our functional currency.

Market risk is the potential loss arising from adverse changes in market rates and market prices such as interest rates, foreign currency rates and changes in the market value of equity instruments. As of December 31, 2021, we had a cash and cash equivalents balance of $78.8 million, consisting of non-interest-bearing deposits and money market funds denominated in U.S. Dollars. We do not believe we are currently exposed to any material market risk. However, changes to our investment portfolio and operations may be subject us to certain risks with respect to fluctuations in interest rates and foreign currency exchange rates in the future. Additionally, inflation could adversely affect the Company’s business, financial condition, or results of operations in the future by increasing our cost of labor and clinical trial costs.

Item 8. Financial Statements and Supplementary Data.

All financial statements required to be filed hereunder are filed as listed under Item 15(a) of this Annual Report on Form 10-K and are incorporated herein by this reference.

There have been no retrospective changes to our statements of operations for any of the quarters within the two years in the period ended December 31, 2021.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

Not Applicable.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2021. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applied its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on this evaluation, our principal executive officer and principal financial officer concluded that as of December 31, 2021, our disclosure controls and procedures were (1) designed to ensure that material information relating to us is made known to our principal executive officer and principal financial officer by others, particularly during the period in which this report was prepared, and (2) effective, in that they provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Internal Control over Financial Reporting

Our management, with the participation of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Exchange Act.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

This Annual Report on Form 10-K does not include a report of management’s assessment regarding internal control over financial reporting as allowed by the SEC for reverse acquisitions between an issuer and a private operating company when it is not possible to conduct an assessment of the private operating company’s internal control over financial reporting in the period between the consummation date of the reverse acquisition and the date of management’s assessment of internal control over financial reporting (see Section 215.02 of the SEC Division of Corporation Finance’s Regulation S-K Compliance & Disclosure Interpretations). As discussed elsewhere in this Annual Report on Form 10-K, we completed the Business Combination on September 2, 2021 pursuant to which we acquired Old Renovacor. Prior to the Business Combination, we were a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, recapitalization, reorganization or similar business combination with one or more businesses. As a result, previously existing internal controls are no longer applicable or comprehensive enough as of the assessment date, as our operations prior to the Business Combination were insignificant compared to those of the consolidated entity post-Business Combination. As a result, management was unable, without incurring unreasonable effort or expense, to complete an assessment of our internal control over financial reporting as of December 31, 2021.

Not Applicable.

No change in our internal control over financial reporting occurred during the fourth quarter of the fiscal year ended December 31, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information.

None.

INDEX TO CONSOLIDATED FINANCIAL STATEMENTS

F-1

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Renovacor, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Renovacor, Inc. (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, convertible preferred stock and stockholders’ equity (deficit) and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
