FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. All statements other than statements of historical fact contained in this Quarterly Report, including without limitation statements regarding our plans to develop, manufacture and commercialize our product candidates, the timing or outcome of our ongoing or planned clinical trials for SQZ-PBMC-HPV, SQZ-AAC-HPV, SQZ-eAPC-HPV or any of our other pipeline product candidates and any future product candidates, the clinical utility of our product candidates, the anticipated impact of the COVID-19 pandemic on our business and operations, including manufacturing, research and development, clinical trials and employees, our cash needs and availability, and the plans and objectives of management for future operations, are forward-looking statements.

The forward-looking statements in this Quarterly Report are only predictions and are based largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements speak only as of the date of this Quarterly Report and are subject to a number of known and unknown risks, uncertainties and other important factors that could cause actual results to differ materially from those projected in the forward-looking statements, including, but not limited to, risks and uncertainties related to our limited operating history; our significant losses incurred since inception and expectation to incur significant additional losses for the foreseeable future; the development of our initial product candidates, upon which our business is highly dependent; the impact of the COVID-19 pandemic on our operations and clinical activities; our need for additional funding and our cash runway; the lengthy, expensive, and uncertain process of clinical drug development, including uncertain outcomes of clinical trials and potential delays in regulatory approval; our ability to maintain our relationships with our third party vendors and strategic collaborators; protection of our proprietary technology, intellectual property portfolio and the confidentiality of our trade secrets; and other important factors discussed under the caption "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and other filings with the U.S. Securities and Exchange Commission.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise.

SQZ BIOTECHNOLOGIES COMPANY

Notes to Unaudited Condensed Consolidated Financial Statements

1. Nature of the Business and Basis of Presentation

SQZ Biotechnologies Company (the “Company”) is a clinical-stage biotechnology company developing cell therapies for patients with cancer, autoimmune and infectious diseases and other serious conditions. The Company uses its proprietary Cell Squeeze technology to physically squeeze cells through a microfluidic chip, temporarily opening the cell membrane and enabling biologic material of interest, or cargo, to diffuse into the cell. The Company is using Cell Squeeze technology to create multiple cell therapy platforms focused on directing specific immune responses. The Company was incorporated in March 2013 under the laws of the State of Delaware.

The Company is subject to a number of risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, the ability to obtain additional financing, protection of proprietary technology, dependence on key personnel, the ability to attract and retain qualified employees, compliance with government regulations, the impact of the COVID-19 pandemic, and the clinical and commercial success of its product candidates. Product candidates currently under development will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Even if the Company’s drug development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

The accompanying consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. Since inception, the Company has funded its operations primarily with payments received in connection with collaboration agreements, proceeds from equity and debt financing, and most recently, with proceeds from its 2020 initial public offering (“IPO”) and its 2021 follow-on offering. On November 10, 2021, the Company entered into an Open Market Sales Agreement (the “Sales Agreement”) with Jefferies LLC (“Jefferies”) to issue and sell up to $75,000,000 in shares of the Company’s common stock from time to time during the term of the Sales Agreement through an “at-the-market” equity offering program under which Jefferies acts as the Company’s sales agent (the “ATM Facility”). During the three and six months ended June 30, 2022, the Company sold 958,663 shares of common stock under the ATM Facility for net proceeds of approximately $3.1 million. The Company has incurred recurring losses since inception, including net losses of $43.3 million for the six months ended June 30, 2022. As of June 30, 2022, the Company had an accumulated deficit of $238.8 million. The Company expects to continue to generate operating losses for the foreseeable future. As of the issuance date of these interim condensed consolidated financial statements, the Company expects that its cash, cash equivalents and marketable securities will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next 12 months. The Company will seek additional funding through private or public equity financings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations or other arrangements. The terms of any financing may adversely affect the holdings or the rights of the Company's stockholders. The future viability of the Company is dependent on its ability to raise additional capital to finance its operations. If the Company is unable to obtain funding, the Company will be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

Impact of the COVID-19 Pandemic

In December 2019, a novel strain of coronavirus, which causes the disease known as COVID-19, was initially reported and since then, COVID-19 has spread globally. In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic and the U.S. government-imposed travel restrictions on travel between the United States, Europe and certain other countries. The outbreak and government measures taken in response have had a significant impact, both direct and indirect, on hospitals, businesses and commerce, as worker shortages have occurred, supply chains have been disrupted, prices have increased and facilities and production have been suspended. The future progression of the pandemic and its effects on the Company’s business and operations are uncertain.

The COVID-19 pandemic has impacted and may continue to impact personnel at third-party manufacturing facilities or the availability or cost of materials, which would disrupt the Company’s supply chain. It also has affected and may continue to affect the Company’s ability to enroll patients in and timely complete its ongoing clinical trials of SQZ-PBMC-HPV, SQZ-AAC-HPV and SQZ-eAPC-HPV and delay the initiation of future clinical trials, disrupt regulatory activities or have other adverse effects on its business and operations.

The Company is monitoring the potential impact of the COVID-19 pandemic on its business and financial statements. To date, the Company has not incurred impairment losses in the carrying values of its assets as a result of the pandemic and it is not aware of any specific related event or circumstance that would require it to revise its estimates reflected in these interim condensed consolidated financial statements. The extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of

operations, financial condition and liquidity, including planned and future clinical trials and research and development costs, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19, the actions taken to contain or treat it, and the duration and intensity of the related effects.

Basis of Presentation

The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, SQZ Biotechnologies Security Corporation, SQZ Biotech HK Limited and SQZ Biotech (Shanghai) Co., Ltd. All intercompany accounts and transactions have been eliminated in consolidation.

2. Summary of Significant Accounting Policies

Unaudited Interim Financial Information

The accompanying condensed consolidated financial statements as of June 30, 2022 and for the three and six months ended June 30, 2022 and 2021 have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. The accompanying condensed consolidated balance sheet as of December 31, 2021 was derived from audited financial statements but does not include all disclosures required by GAAP. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 filed with the SEC on March 16, 2022. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s consolidated financial position as of June 30, 2022, the consolidated results of operations for the three and six months ended June 30, 2022 and 2021, and the consolidated cash flows for the six months ended June 30, 2022 and 2021 have been made. The Company’s consolidated results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results of operations that may be expected for the full year or any other subsequent interim period.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, revenue recognition, the accrual of research and development expenses, the valuation of common stock and the valuation of stock-based awards. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates, judgments and methodologies as there are changes in circumstances, facts and experience. Actual results may differ from those estimates or assumptions.

Segment Information

The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The Company is developing methods of engineering cell function and therapies for the treatment of patients across a range of indications. The Company has determined that its chief operating decision maker is its Chief Executive Officer. The Company’s chief operating decision maker reviews the Company’s financial information on a consolidated basis for purposes of allocating resources and assessing financial performance.

Revenue Recognition for Government Grants

The Company generates revenue from government contracts that reimburse the Company for certain allowable costs for funded projects. For contracts with government agencies where the funding arrangement is considered central to the Company’s ongoing operations, the Company classifies the recognized funding received as revenue. Revenue from government grants is recognized as the qualifying expenses related to the contracts are incurred, provided that there is reasonable assurance of recoverability. The Company submits a budget, which outlines the expected project costs, to the funding government agency on a periodic basis. If the government agency approves the project proposed by the Company, the government agency generally funds the project upon receipt of the support for the costs incurred. Revenue recognized upon incurring qualifying expenses in advance of receipt of funding is recorded as unbilled receivables, a component of prepaid expenses and other current assets, in the consolidated balance sheet. The related costs incurred by the Company are included in research and development expense in the Company’s consolidated statements of operations and

comprehensive loss. In certain cases, the Company may obtain grants from an economic development agency that are not central to the Company's ongoing business. The income from these grants is recognized within Other income (expense), net in the consolidated statement of operations and comprehensive loss when there is reasonable assurance of recoverability.

Recently Issued Accounting Pronouncements

The Company qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has elected not to “opt out” of the extended transition related to complying with new or revised accounting standards, which means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company will adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and will do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. The Company may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for nonpublic companies.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in the earlier recognition of credit losses, if any. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief (“ASU 2019-05”), which provides additional implementation guidance on the previously issued ASU 2016-13. For the Company, this guidance is effective for fiscal years beginning after December 15, 2022. The Company is currently evaluating the impact that the adoption of ASU 2016-13 will have on its consolidated financial statements, however the Company does not expect that the standard will have a material impact on its consolidated financial statements.

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”), which simplifies the accounting for income taxes by eliminating certain exceptions, including the approach for intraperiod tax allocation, the accounting for income taxes in an interim period, hybrid taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The Company adopted this standard as of January 1, 2022 and the standard did not have a material impact on its consolidated financial statements.

In November 2021, the FASB issued ASU 2021-10, Disclosures by Business Entities about Government Assistance, which requires business entities to provide certain disclosures when they have 1) received government assistance and 2) use a grant or contribution accounting model by analogy to other accounting guidance. The Company adopted this standard as of January 1, 2022 and the standard did not have a material impact on its consolidated financial statements.

7. Income Taxes

For the three and six months ended June 30, 2022 and 2021, the Company recorded no income tax benefits for the net operating losses incurred or for the research and development tax credits generated in each period, due to its uncertainty of realizing a benefit from those items. Substantially all of the Company’s operating losses since inception have been generated in the United States.

8. Commitments and Contingencies

Leases

The Company’s commitments under its leases are described in Note 9.

License and Supply Agreements

License Agreement with Massachusetts Institute of Technology

In December 2015, the Company entered into an exclusive patent license agreement with the Massachusetts Institute of Technology (“MIT”) (the “MIT Agreement”). The MIT Agreement replaced a May 2013 exclusive agreement with MIT. Under the MIT Agreement, the Company received an exclusive license under the licensed patent rights to develop, manufacture and commercialize any products related to certain intracellular delivery methods that were developed at MIT.

As of June 30, 2022 and December 31, 2021, the Company had no liabilities related to the MIT Agreement. During each of the three and six months ended June 30, 2022 and 2021, the Company did not recognize any research and development expense under the sublicense terms of the MIT Agreement.

Manufacturing Services Agreements

The Company has entered into agreements with a contract manufacturing organization to provide manufacturing services related to its product candidates. As of June 30, 2022, the Company had no non-cancelable payments under these agreements, as amended, other than the amounts included in the current portion of operating lease liabilities on the Company's consolidated balance sheets.

401(k) Plan

The Company sponsors a 401(k) defined contribution benefit plan (the “401(k) Plan”), which covers all employees who meet certain eligibility requirements as defined in the 401(k) Plan and allows participants to defer a portion of their annual compensation on a pre-tax basis. Contributions to the 401(k) Plan may be made at the discretion of management. For each of the three months ended June 30, 2022 and 2021, the Company contributed $0.1 million to the 401(k) Plan. For each of the six months ended June 30, 2022 and 2021, the Company contributed $0.2 million to the 401(k) Plan.

Indemnification Agreements

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to its vendors, lessors, contract research organizations, business partners and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with its executive officers and members of its board of directors that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. The Company has not incurred any material costs as a result of such indemnification agreements and is not currently aware of any indemnification claims.

Legal Proceedings

The Company is not currently party to any material legal proceedings. At each reporting date, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company expenses as incurred the costs related to such legal proceedings.

9. Leases

Table of Contents

As of June 30, 2022, the Company leases its office and laboratory facilities under a non-cancelable operating lease entered into in December 2018, which included lease incentives, payment escalations and rent holidays. In addition, the Company has an agreement entered into in April 2019 with a contract manufacturing supplier that is considered an embedded lease because the Company has substantially all the economic benefits of the related asset and can direct its use. The Company had not entered into any financing leases or any short-term operating leases as of June 30, 2022 and December 31, 2021.

10. License and Collaboration Agreements

2017 License and Collaboration Agreement with Roche

In April 2017, the Company entered into a second license and collaboration agreement with Roche (the “2017 Roche Agreement”) to allow Roche to use the Company’s Cell Squeeze technology to enable gene editing of immune cells to discover new targets in cancer immunotherapy. The 2017 Roche Agreement included several licenses granted by Roche to the Company and by the Company to Roche in order to conduct a specified research program in accordance with a specified research plan. In the first quarter of 2022, the 2017 Roche Agreement was terminated and all active work streams under the 2017 Roche Agreement were concluded. As of December 31, 2021, the Company determined that it expected to incur no additional costs to satisfy the remaining performance obligations under the 2017 Roche Agreement and all remaining deferred revenue was recognized as of that date. There was no revenue recorded under this agreement during the three and six months ended June 30, 2022.

During the three and six months ended June 30, 2021, the total costs expected to be incurred to satisfy the performance obligation under the 2017 Roche Agreement decreased by $0.1 million and $0.3 million, respectively. The Company recognized revenue of $0.2 million and $0.8 million during the three and six months ended June 30, 2021, respectively.

2018 License and Collaboration Agreement with Roche

In October 2018, the Company entered into a license and collaboration agreement with Roche (the “2018 Roche Agreement”) to jointly develop certain products based on mononuclear antigen presenting cells (“APCs”), including human papillomavirus (“HPV”), using the SQZ APC platform for the treatment of oncology indications. The Company granted Roche a non-exclusive license to its intellectual property, and Roche granted the Company a non-exclusive license to its and its affiliates’ intellectual property for the purpose of performing research activities. In connection with this agreement, the parties terminated an earlier agreement. The 2018 Roche Agreement has a term that extends until all royalty, profit-share and other payment obligations expire or have been satisfied. Roche has the right to terminate the 2018 Roche Agreement, in whole or on a product-by-product basis, upon a specified amount of notice to the

11


Table of Contents

Company. The Company or Roche may terminate the agreement if the other party fails to cure its material breach within a specified period after receiving notice of such breach.

Under the 2018 Roche Agreement, Roche was granted option rights to obtain an exclusive license to develop APC products or products derived from the collaboration programs on a product-by-product basis. These option rights are exercisable upon the achievement of clinical Phase 1 proof of concept and expire, if unexercised, as of a date specified in the agreement. In addition, Roche was granted an option right to obtain an exclusive license to develop a Tumor Cell Lysate (“TCL”) product. This option right is exercisable upon the achievement of clinical proof of concept and expires, if unexercised, as of a date specified in the agreement. For each of the APC products and TCL product, once Roche exercises its option and pays a specified incremental amount ranging from $15.0 million to $50.0 million for APC products and of $100.0 million for the TCL product, Roche will receive worldwide, exclusive commercialization rights for the licensed products, subject to the Company’s alternating option to retain U.S. APC commercialization rights. The Company will retain worldwide commercialization rights to any APC products or the TCL product for which Roche elects not to exercise its applicable option. For the first APC product that Roche exercises its option, Roche will receive worldwide, exclusive commercialization rights for the licensed product. On a product-by-product basis for the APC products, after the first product option is exercised by Roche and for every other product for which Roche exercises its option, the Company will retain an option to obtain the exclusive commercialization rights in the United States. Upon exercise of the TCL option by Roche, (i) the Company will be entitled to receive the aforementioned milestone payment of $100.0 million and (ii) profits from the TCL product will be shared equally by the Company and Roche. Through June 30, 2022, Roche had not exercised any of its options under the 2018 Roche Agreement.

Under the 2018 Roche Agreement, the Company received an upfront payment of $45.0 million and is eligible to receive (i) reimbursement of a mid-double-digit percentage of its development costs; (ii) aggregate milestone payments on a product-by-product basis of up to $1.6 billion upon the achievement of specified milestones, consisting of up to $217.0 million of development milestone payments, up to $240.0 million of regulatory milestone payments and up to $1.2 billion of sales milestone payments; and (iii) tiered royalties on annual net sales of APC and TCL products licensed under the agreement, as described below. The Company received the upfront payment of $45.0 million in October 2018 upon execution of the agreement. In addition, during the second quarter of 2019, the Company received a payment of $10.0 million following the achievement of the first development milestone under the 2018 Roche Agreement related to submission by the Company of preclinical data to the U.S. Food and Drug Administration (“FDA”). During the first quarter of 2020, the Company received a payment of $20.0 million following the achievement of the second development milestone under the 2018 Roche Agreement related to first-patient dosing in a Phase 1 clinical trial. In the first quarter of 2022, the Company received a milestone payment of $3.0 million having achieved in the fourth quarter of 2021 the following: (i) the endorsement by an independent panel that it could advance its SQZ-PBMC-HPV clinical trial to combination therapy using checkpoint inhibitors and (ii) the initiation of that therapy.

Roche will pay tiered royalties based on annual net sales of APC and TCL products. If Roche exercises its option to obtain a license to commercialize an APC product, Roche will pay the Company tiered royalties on annual net sales of that licensed product at rates ranging from a mid-single-digit percentage to a mid-teens percentage, depending on net sales of the product. If the Company exercises its option to obtain a license to commercialize an APC product in the United States, it will pay Roche tiered royalties on annual net sales of that licensed product at rates ranging from a mid-single-digit percentage to a mid-teens percentage, depending on net sales of the product in the United States. For APC products selected by Roche, rather than mutually, Roche will pay the Company royalties on annual net sales of that licensed product at rates ranging from a mid-single-digit percentage to a high single-digit percentage, depending on net sales of the product. For APC products that are selected mutually and for which the Company has not exercised its option to commercialize the product in the United States, Roche will pay the Company tiered royalties on annual net sales of that licensed product at a rate ranging from a high single-digit percentage to a mid-teens percentage, depending on net sales of the product. For TCL products, Roche will pay the Company tiered royalties on the aggregate net sales of all TCL products at rates ranging from either a mid-single digit percentage to a percentage in the low twenties, with the caveat that the rates for sales in the United States may instead range from a low-teens percentage to a percentage in the mid-twenties, depending on whether and when the Company opts out of sharing certain profits and costs of commercializing the TCL product in the United States with Roche.

The Company identified three performance obligations at the outset of the 2018 Roche Agreement: (1) the license to the Company’s intellectual property, the research and development activities related to HPV through Phase 1 clinical trials under a specified research plan, and the manufacturing of the Company’s SQZ APC platform and equipment in order to support the HPV research plan (the “first performance obligation”); (2) the license to the Company’s intellectual property and the research and development activities on next-generation APCs (the “second performance obligation”); and (3) the license to the Company’s intellectual property and the research and development activities on TCL (the “third performance obligation”).

During the fourth quarter of 2019, the Company evaluated its overall program priorities and determined that it would continue to focus its resources on progressing the specified APC programs related to the 2018 Roche Agreement as well as its Activating Antigen Carriers (“AAC”) and Tolerizing Antigen Carriers (“TAC”) platforms. As a result of its continuing focus on these specific programs, the Company reduced the level of priority of the TCL research activities under the 2018 Roche Agreement and expects to perform such TCL

research activities over a longer time period than as originally expected under the specified research plan of the agreement. Since the fourth quarter of 2019, the Company has classified $9.2 million as non-current deferred revenue, which will remain unrecognized as revenue until TCL research activities resume or the 2018 Roche Agreement is modified by the Company and Roche.

The Company separately recognizes revenue associated with each of the three performance obligations as the research, development and manufacturing services are provided using an input method, based on the cumulative costs incurred compared to the total estimated costs expected to be incurred to satisfy each performance obligation. The transfer of control to the customer occurs over the time period that the research and development services are to be provided by the Company, and this cost-to-cost method is, in management’s judgment, the best measure of progress towards satisfying each performance obligation. The amounts received that have not yet been recognized as revenue are deferred as a contract liability in the Company’s consolidated balance sheet and will be recognized over the remaining research and development period until each performance obligation is satisfied.

During the three and six months ended June 30, 2022 and 2021, there were no significant changes in the total estimated costs expected to be incurred to satisfy the performance obligations under the 2018 Roche Agreement. The Company recognized revenue of $3.0 million and $4.3 million during the three months ended June 30, 2022 and 2021, respectively, under this agreement. The Company recognized revenue of $5.9 million and $9.1 million during the six months ended June 30, 2022 and 2021, respectively, under this agreement. As of June 30, 2022, the Company recorded as a contract liability deferred revenue related to the 2018 Roche Agreement of $15.3 million, of which $6.1 million was a current liability. As of June 30, 2022, the research and development services related to the performance obligations were expected to be performed over a remaining period of six months. As of December 31, 2021, the Company recorded as a contract liability deferred revenue related to the 2018 Roche Agreement of $21.2 million, of which $12.0 million was a current liability.

As of June 30, 2022 and December 31, 2021, the expected remaining period of performance of the Company’s research and development services related to the third performance obligation was not determinable, and it will not become determinable until TCL research activities resume or the 2018 Roche Agreement is modified by the Company and Roche.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission, or SEC, on March 16, 2022 (the “2021 Form 10-K”). Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of our 2021 Form 10-K, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage biotechnology company focused on unlocking the full potential of cell therapies to benefit patients with cancer, autoimmune and infectious diseases, and other serious conditions. The company was founded on the therapeutic potential of Cell Squeeze® technology, our proprietary technology which allows for rapid delivery of a variety of cargo into different cell types. We aim to create multiple cell therapies that drive the immune system to combat diseases.

In oncology, we are developing cell therapy platforms that are based on directing tumor antigen-specific immune activation via engineered antigen presentation. We believe that by engineering physiological antigen presentation signals in subsets of peripheral blood cells that act on immune priming pathways, we have the potential to develop cell therapies that are designed to be potent drivers of tumor-specific immunity, well-tolerated, administered without lymphodepleting preconditioning or hospitalization, and produced in under 24 hours. We have three oncology candidates in clinical trials across our SQZ® Antigen Presenting Cell, or APC, SQZ® enhanced APC, or eAPC, and SQZ® Activating Antigen Carrier, or AAC, cell therapy platforms. In our autoimmune diseases portfolio, we are developing our SQZ® Tolerizing Antigen Carrier, or TAC, cell therapy platform with the aim to restore immune tolerance to self-antigens or other autoimmune disease-associated antigens that are central to disease pathogenesis.

In 2021, we executed on several key areas of our pipeline and advanced our APC platform objectives. As of December 31, 2021, we have dosed 20 patients in our Phase 1 trial for our lead APC candidate, SQZ-PBMC-HPV, in HPV16+ advanced solid tumors. We reported interim data from the first three monotherapy dose-escalation cohorts at the 2021 American Society of Clinical Oncology, or ASCO, Annual Meeting, and presented interim safety, biomarker, and clinical data from the highest dose SQZ-PBMC-HPV monotherapy cohort at the 2021 European Society for Medical Oncology Immuno-Oncology, or ESMO-IO, Congress. Key observations from the reported data include, as of a cutoff date of October 8, 2021 (n=18 patients):

SQZ-PBMC-HPV induced a radiographic response and led to symptomatic improvement as a monotherapy treatment in a checkpoint refractory head-and-neck cancer patient
Across all dose levels, there were no observed treatment-related Grade 3 or greater serious adverse events, and no patient met the dose limiting toxicity, or DLT, criteria
Autologous cell therapy manufacturing was demonstrated in under 24 hours for all monotherapy patients, with multiple doses produced and an average vein-to-vein time of approximately one week

We have advanced our trial to evaluate SQZ-PBMC-HPV in combination with checkpoint inhibitor therapies, and are continuing to enroll patients in the highest dose monotherapy cohort. We are targeting additional data in the second half of 2022. In April 2022, the U.S. Food and Drug Administration, or FDA, granted Fast Track Designation to SQZ-PBMC-HPV for the treatment of HPV16+ advanced or metastatic solid tumors.

We have continued to build upon the progress of our SQZ® APC platform through the development of the novel SQZ® eAPC platform. Our lead eAPC product candidate leverages the added capabilities and functionality of multiple antigen presentation and immunological signals achieved through multiplexed mRNA delivery to diverse immune cell types. In January 2022, we received allowance to proceed with clinical trials from the FDA under our Investigational New Drug, or IND, application for SQZ-eAPC-HPV, our lead eAPC candidate engineered with HPV16 antigens and costimulatory signals. We initiated the SQZ-eAPC-HPV trial, the COMMANDER-001 Phase 1/2 study, in patients with HPV16+ advanced solid tumors in the first half of 2022. We anticipate announcing initial interim data from this study in the second half of 2022. In addition to our efforts in the oncology field, we are also continuing to advance development of the eAPC platform in the infectious diseases field.

In 2021, we received allowance to proceed with clinical trials from the FDA under our IND for SQZ-AAC-HPV, our lead AAC product candidate derived from red blood cells engineered with tumor-specific antigens. We are currently enrolling monotherapy cohorts as part of the Phase 1 ENVOY-001 trial to assess safety and tolerability as well as secondary outcome measures of the investigational SQZ-AAC-HPV therapy in HPV16+ advanced solid tumors, and plan to announce initial interim data in the second half of 2022.

We are also advancing our SQZ® TAC platform focused on creating novel and proprietary cell therapies as it relates to modulating or restoring immune tolerance. We have selected Celiac disease as the first proposed autoimmune indication for SQZ® TAC platform development. We believe the evidence of a causal disease antigen and T-cell driven pathology, and the substantial unmet need for a

15


Table of Contents

tolerizing treatment option provide a compelling opportunity for us to pursue Celiac disease. We presented characterization of TAC-mediated mechanisms of antigen-specific tolerance in preclinical models at the 2021 Federation of Clinical Immunology Societies, or FOCIS, Meeting. We anticipate further development of our TAC-Celiac candidate through IND-enabling studies in 2022 to support an IND submission in the first half of 2023, and, in parallel, are planning to use our proprietary, point-of-care manufacturing system for the production of the clinical batches.

Since our inception, we have focused substantially all of our resources on building our Cell Squeeze technology, establishing and protecting our intellectual property portfolio, conducting research and development activities, developing our manufacturing process and manufacturing product candidate materials, preparing for and initiating clinical trials of our product candidates, organizing and staffing our company, business planning, raising capital and providing general and administrative support for these operations. We do not have any products approved for sale and have not generated any revenue from product sales. Through June 30, 2022, we have funded our operations primarily with upfront and milestone payments received under our collaboration agreements with Hoffman La Roche Inc. and F. Hoffman La Roche Ltd. (together, "Roche",) and with proceeds from equity and debt offerings, most recently from our initial public offering, or IPO, and follow-on public offering of common stock, or the Follow-on Offering. During the three and six months ended June 30, 2022, we raised $3.1 million, utilizing an “at-the-market” offering facility, pursuant to which we sold 958,663 shares of our common stock.

Since our inception, we have incurred significant operating losses. Our ability to generate any product revenue or product revenue sufficient to achieve profitability will depend on the successful development and eventual commercialization of one or more of our product candidates. We reported a net loss of $43.3 million for the six months ended June 30, 2022. As of June 30, 2022, we had an accumulated deficit of $238.8 million. We expect to continue to incur significant expenses and increasing operating losses for at least the next several years. We expect that our expenses and capital requirements will increase substantially in connection with our ongoing activities, particularly if and as we:

conduct clinical trials for our product candidates, including our ongoing clinical trials of SQZ-PBMC-HPV, SQZ-AAC-HPV and SQZ-eAPC-HPV, both in the United States and abroad;
further develop our Cell Squeeze® technology;
continue to develop additional product candidates;
maintain, expand and protect our intellectual property portfolio;
hire additional clinical, scientific manufacturing and commercial personnel;
expand external and/or establish internal commercial manufacturing sources and secure supply chain capacity sufficient to provide commercial quantities of any product candidates for which we may obtain regulatory approval;
acquire or in-license other product candidates and technologies;
seek regulatory approvals for any product candidates that successfully complete clinical trials;
establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain regulatory approval; and
add operational, financial and management information systems and personnel to support our product development, clinical execution and planned future commercialization efforts, as well as to continue to support our status as a public company.

We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for 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 marketing, distribution or licensing arrangements. Currently, market conditions in the biotechnology sector are challenging due to ongoing global and economic uncertainties. Accordingly, we may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as, and when, needed, we would have to significantly delay, scale back or discontinue the development and commercialization of one or more of our product candidates.

Because of the numerous risks and uncertainties associated with cell therapy 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 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 be forced to reduce or terminate our operations.

We believe that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2023. See “—Liquidity and Capital Resources.”

Impact of the COVID-19 Pandemic

The COVID-19 pandemic and government measures taken in response have had a significant impact, both direct and indirect, on hospitals, businesses and commerce, as worker shortages have occurred, supply chains have been disrupted, prices have increased and facilities and production have been suspended. The future progression of the pandemic and its effects on our business and operations are uncertain.

The COVID-19 pandemic has impacted and may continue to impact personnel at third-party manufacturing facilities or the availability or cost of materials, which would disrupt our supply chain. It also has affected and may continue to affect our ability to enroll patients in and timely complete our ongoing clinical trials of SQZ-PBMC-HPV, SQZ-AAC-HPV and SQZ-eAPC-HPV and delay the initiation of future clinical trials, disrupt regulatory activities or have other adverse effects on our business and operations. For example, we have experienced delays in receiving supplies of raw materials for our preclinical activities due to the impact of COVID-19 on our suppliers’ ability to timely manufacture these materials, and we have experienced an increase in the transportation cost of our product candidates due to the decreased availability of commercial flights. In addition, we have experienced delays in opening clinical trial sites and sites that are open may also have challenges enrolling patients. Further, staff shortages, including staff that are required to conduct certain testing, such as biopsies, at our clinical sites or at third-party vendors have resulted in delays in site initiations and in some tests not being properly or timely performed or being delayed. In response to the public health directives and to help reduce the risk to our employees, we took precautionary measures, including implementing work-from-home policies for our administrative employees and staggered work times for our lab employees. We plan to continue to implement restrictive measures and are assessing when and how to resume normal operations. The effects of the public health directives and our work-from-home policies may negatively impact productivity, disrupt our business and delay our clinical programs and timelines and future clinical trials, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. These and similar, and perhaps more severe, disruptions in our operations could negatively impact our business, results of operations and financial condition, including our ability to obtain financing.

The pandemic and related uncertainties have already caused significant disruptions in the financial markets, and may continue to cause such disruptions, which could impact our ability to raise additional funds to support our operations. Moreover, the pandemic has significantly impacted inflation and economies worldwide and could result in adverse effects on our business and operations. We are monitoring the potential impact of the COVID-19 pandemic on our business and financial statements. To date, we have not incurred impairment losses in the carrying values of our assets as a result of the pandemic and we are not aware of any specific related event or circumstance that would require us to revise our estimates reflected in our interim condensed consolidated financial statements. We cannot be certain what the overall impact of the COVID-19 pandemic will be on our business and people. The extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations, financial condition, and liquidity, including planned and future clinical trials and research and development costs, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19, the actions taken to contain or treat it, and the duration and intensity of the related effects.

Components of Our Results of Operations

Revenue

To date, we have not generated any revenue from product sales and do not expect to do so for the next several years. All of our revenue to date has been derived from three collaboration agreements with Roche, and, to a lesser extent, from government grants.

If our development efforts for our product candidates are successful and result in regulatory approval, or in license or additional collaboration agreements with third parties, we may generate revenue in the future from product sales, payments from additional collaboration or license agreements that we may enter into with third parties, or any combination thereof. We expect that our revenue for the next several years will be derived primarily from our collaboration agreements with Roche as well as any additional collaborations that we may enter into in the future. We cannot provide assurance as to the timing of future milestone or royalty payments or that we will receive any of these payments at all.

Collaboration Revenue

2017 License and Collaboration Agreement with Roche

In April 2017, we entered into a second license and collaboration agreement with Roche (the “2017 Roche Agreement”) to allow Roche to use our Cell Squeeze® technology to enable gene editing of immune cells to discover new targets in cancer immunotherapy. The 2017 Roche Agreement included several licenses granted by Roche to us and by us to Roche in order to conduct a specified research program in accordance with a specified research plan. In the first quarter of 2022, the 2017 Roche Agreement was terminated and all active work

17


Table of Contents

streams under the 2017 Roche Agreement were concluded. As of December 31, 2021, we had determined that we expected to incur no additional costs to satisfy the remaining performance obligations under the 2017 Roche Agreement and all remaining deferred revenue was recognized as of that date. There was no revenue recorded under this agreement during the three and six months ended June 30, 2022.

During the three and six months ended June 30, 2021, the total costs expected to be incurred to satisfy the performance obligation under the 2017 Roche Agreement decreased by $0.1 million and $0.3 million, respectively. We recognized revenue of $0.2 million and $0.8 million during the three and six months ended June 30, 2021, respectively.

2018 License and Collaboration Agreement with Roche

In October 2018, we entered into a license and collaboration agreement with Roche, or the 2018 Roche Agreement, to jointly develop certain products based on mononuclear antigen presenting cells, or APCs, including human papillomavirus, or HPV, using our SQZ APC platform for the treatment of oncology indications. We granted Roche a non-exclusive license to our intellectual property, and Roche granted us a non-exclusive license to its and its affiliates’ intellectual property for the purpose of performing research activities. In connection with this agreement, the parties terminated an earlier agreement.

Under the 2018 Roche Agreement, Roche was granted option rights to obtain an exclusive license to develop APC products or products derived from the collaboration programs on a product-by-product basis and to develop a Tumor Cell Lysate, or TCL, product. For each of the APC products and TCL product, once Roche exercises its option and pays a specified incremental amount, Roche will receive worldwide, exclusive commercialization rights for the licensed products. Through June 30, 2022, Roche had not exercised any of its options under the 2018 Roche Agreement.

Under the 2018 Roche Agreement, we received an upfront payment of $45.0 million and are eligible to receive (i) reimbursement of a mid-double-digit percentage of our development costs; (ii) aggregate milestone payments on a product-by-product basis of up to $1.6 billion upon the achievement of specified milestones, consisting of up to $217.0 million of development milestone payments, up to $240.0 million of regulatory milestone payments and up to $1.2 billion of sales milestone payments; and (iii) tiered royalties on annual net sales of APC and TCL products licensed under the agreement at specified rates ranging from a mid-single-digit percentage to a percentage in the mid-twenties. We received the upfront payment of $45.0 million in October 2018 upon execution of the agreement. In addition, during the second quarter of 2019, we received a payment of $10.0 million following the achievement of the first development milestone under the 2018 Roche Agreement related to submission by us of preclinical data to the FDA. During the first quarter of 2020, we received a payment of $20.0 million following the achievement of the second development milestone under the 2018 Roche Agreement related to first-patient dosing in a Phase 1 clinical trial. In the first quarter of 2022, we received a milestone payment of $3.0 million having achieved in the fourth quarter of 2021 the following: (i) the endorsement by an independent panel that we could advance our SQZ-PBMC-HPV clinical trial to combination therapy using checkpoint inhibitors and (ii) the initiation of that therapy.

We identified three performance obligations at the outset of the 2018 Roche Agreement: (1) the license to our intellectual property, the research and development activities related to HPV through Phase 1 clinical trials under a specified research plan, and the manufacturing of our SQZ APC platform and equipment in order to support the HPV research plan (the “first performance obligation”); (2) the license to our intellectual property and the research and development activities on next-generation APCs (the “second performance obligation”); and (3) the license to our intellectual property and the research and development activities on TCL (the “third performance obligation”).

In addition, we determined that the upfront payment of $45.0 million as well as the reimbursable costs of $10.8 million estimated by us constituted the entirety of the consideration to be included in the transaction price. This transaction price of $55.8 million was initially allocated to the three performance obligations based on the relative standalone selling price of each obligation. The potential milestone payments that we may be eligible to receive were excluded from the transaction price at the outset of the arrangement. We reevaluate the transaction price at the end of each reporting period and as uncertain events are resolved or other changes in circumstances occur, and, if necessary, we will adjust our estimate of the transaction price.

We separately recognize revenue associated with each of the three performance obligations as the research, development and manufacturing services are provided using an input method, based on the cumulative costs incurred compared to the total estimated costs expected to be incurred to satisfy each performance obligation. The amounts received from Roche that have not yet been recognized as revenue are deferred as a contract liability in our consolidated balance sheet and will be recognized over the remaining research and development period until each performance obligation is satisfied.

During the fourth quarter of 2019, we evaluated our overall program priorities and determined that we would continue to focus our resources on progressing the specified APC programs related to the 2018 Roche Agreement as well as our SQZ AAC and SQZ TAC platforms. As a result of our continuing focus on these specific programs, we reduced the level of priority of the TCL research activities under the 2018 Roche Agreement and expect to perform such TCL research activities over a longer time period than as originally expected under the specified research plan of the agreement. Since the fourth quarter of 2019, we have classified $9.2 million as

18


Table of Contents

non-current deferred revenue, which will remain unrecognized as revenue until TCL research activities resume or the 2018 Roche Agreement is modified by us and Roche.

 

During the three months ended June 30, 2022 and 2021, there were no significant changes in the total estimated costs expected to be incurred to satisfy the performance obligations under the 2018 Roche Agreement. We recognized revenue of $3.0 million and $4.3 million during the three months ended June 30, 2022 and 2021, respectively, under this agreement. We recognized revenue of $5.9 million and $9.1 million during the six months ended June 30, 2022 and 2021, respectively, under this agreement. As of June 30, 2022, we recorded as a contract liability deferred revenue related to the 2018 Roche Agreement of $15.3 million, of which $6.1 million was a current liability. As of June 30, 2022, the research and development services related to the performance obligations were expected to be performed over a remaining period of six months.

 

As of June 30, 2022, the expected remaining period of performance of our research and development services related to the third performance obligation was not determinable, and it will not become determinable until TCL research activities resume or the 2018 Roche Agreement is modified by us and Roche.

 

Grant Revenue

We generate revenue from a government contract with the National Institutes of Health (NIH), which reimburses us for certain allowable costs for funded projects, plus an agreed upon fee. Revenue from government grants is recognized as the qualifying expenses related to the contracts are incurred, provided that there is reasonable assurance of recoverability. Revenue recognized upon incurring qualifying expenses in advance of receipt of funding is recorded as unbilled receivables, a component of prepaid expenses and other current assets, in our consolidated balance sheet.

Operating Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research activities, including development of our product candidates and costs incurred under our collaboration arrangements with Roche, which include:

employee-related expenses, including salaries, related benefits and stock-based compensation expense for employees engaged in research and development functions;
expenses incurred in connection with the preclinical and clinical development of our product candidates and research programs, including under agreements with third parties, such as consultants, contractors and contract research organizations, or CROs;
the costs of developing and scaling our manufacturing process and of manufacturing our product candidates for use in our preclinical studies and clinical trials, including the costs under agreements with third parties, such as consultants, contractors and contract manufacturing organizations, or CMOs;
laboratory and consumable materials and research materials;
facilities, depreciation and other expenses, which include direct and allocated expenses for rent and utilities; and
payments made under third-party licensing agreements.

We expense research and development costs as incurred. Nonrefundable 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. Upfront payments under license agreements are expensed upon receipt of the license, and annual maintenance fees under license agreements are expensed in the period in which they are incurred. Milestone payments under license agreements are accrued, with a corresponding expense being recognized, in the period in which the milestone is determined to be probable of achievement and the related amount is reasonably estimable.

Our direct research and development expenses are tracked on a program-by-program basis and consist of external costs and fees paid to consultants, contractors, CMOs and CROs in connection with our preclinical and clinical development and manufacturing activities. Such program costs also include the external costs of laboratory and consumable materials and costs of raw materials that are directly attributable to and incurred for any single program. We do not allocate employee costs, costs associated with our platform development and discovery efforts, payments made under third-party licensing agreements, costs of laboratory supplies and consumable materials that are not directly attributable to any single program, and facilities expenses, including rent, depreciation and other indirect costs, to specific product development programs because these costs are deployed across multiple programs and our platform technology and, as such, are not separately classified.

Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect that our research and development expenses will increase substantially in connection with our planned preclinical and clinical development activities in the near term and in the future, particularly should Roche determine not to exercise its options and we decide to continue clinical development of a product candidate. At this time, we cannot accurately estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical and clinical development of any of our product candidates. The successful development of our product candidates is highly uncertain. This is due to the numerous risks and uncertainties associated with product development, including the following:

the timing and progress of preclinical and clinical development activities, including geographic expansion of our clinical sites into Europe and Asia;
the number and scope of preclinical and clinical programs we decide to pursue;
raising additional funds necessary to complete preclinical and clinical development of our product candidates;
the progress of the development efforts of parties with whom we have entered, or may enter, into collaboration arrangements;
our ability to maintain our current research and development programs and to establish new ones;
our ability to establish new licensing or collaboration arrangements;
the successful initiation and completion of clinical trials with safety, tolerability and efficacy profiles that are satisfactory to the FDA or any comparable foreign regulatory authority;
the receipt and related terms of regulatory approvals from applicable regulatory authorities;
the availability of specialty raw materials for use in production of our product candidates;
our ability to consistently manufacture our product candidates for use in clinical trials;
our ability to establish and operate a manufacturing facility, or secure manufacturing supply through relationships with third parties;
our ability to obtain and maintain patents, trade secret protection and regulatory exclusivity, both in the United States and internationally; and
our ability to protect our rights in our intellectual property portfolio.

A change in the outcome of any of these variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. In addition, we may never succeed in obtaining regulatory approval for any of our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, for personnel in executive, finance and administrative functions. General and administrative expenses also include direct and allocated facility-related costs as well as professional fees for legal, patent, consulting, investor and public relations, accounting, and audit services. We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research activities and development of our product candidates. We also anticipate that we will incur increased accounting, audit, legal, regulatory, compliance and director and officer insurance costs as well as investor and public relations expenses associated with operating as a public company.

Other Income (Expense)

Interest Income

Interest income consists of interest earned on our cash equivalents balances.

Other Income (Expense), Net

Other income (expense), net consists of miscellaneous income and expense unrelated to our core operations.

Income Taxes

Since our inception, we have not recorded any income tax benefits for the net losses we have incurred in each year or for our earned research and development tax credits, as we believe, based upon the weight of available evidence, that it is more likely than not that all of our net operating loss carryforwards and tax credit carryforwards will not be realized.

Revenue

Collaboration revenue decreased by $1.5 million to $3.0 million for the three months ended June 30, 2022, compared to $4.5 million for the three months ended June 30, 2021. The decrease in revenue was primarily due to the following:

an increase in the expected remaining performance period of the 2018 Roche Agreement at the end of 2021, resulting in a longer period over which revenue is recognized in 2022 as compared to the same period in 2021.
a decrease in the number of performance obligations for which revenue is being recognized. During the three months ended June 30, 2021, we recognized revenue of $0.2 million under the 2017 Roche Agreement whereas during the three months ended March 31, 2022, we recognized no revenue under this agreement as the performance obligations were fully satisfied.

Grant revenue increased by $0.2 million. We were awarded a government grant by the NIH at the end of the first quarter of 2022 and began performing services under this grant during the second quarter of 2022.

Research and development expenses increased by $1.1 million to $18.8 million for the three months ended June 30, 2022, from $17.7 million for the three months ended June 30, 2021. The net increase was primarily due to the following:

 

SQZ-PBMC-HPV program costs decreased by $0.6 million primarily due to a decrease in allocated manufacturing costs partially offset by an increase in direct manufacturing expenses.
SQZ-AAC-HPV program costs increased by $0.5 million primarily as a result of an increase in allocated manufacturing costs partially offset by a decrease in technology transfer costs and a decrease in research materials costs.

Table of Contents

SQZ-eAPC-HPV program costs decreased by $1.5 million due to a decrease in manufacturing, materials and setup costs partially offset by an increase in allocated manufacturing costs and an increase in clinical trial-related costs.
Other program costs increased by $1.2 million primarily due to expenses incurred on developing a point-of-care system to manufacture our product candidates.
The increase in personnel-related costs of $1.4 million was primarily due to a $0.2 million increase in stock-based compensation expense and a $1.2 million increase in salary and benefit costs as a result of increased headcount in our research and development function.
The changes in facilities, laboratory and consumable materials and platform-related external services and other costs were not significant.

an increase of $0.6 million in personnel-related costs due to a $0.4 million increase in stock-based compensation expense and a $0.2 million increase in salary and benefit costs as a result of increased headcount and higher salary costs.
an increase of $0.2 million in professional, consultant and patent related costs due to higher legal costs.
an increase of $0.2 million in facility related and other costs primarily due to higher operational costs.

Interest Income

Interest income for the three months ended June 30, 2022 and 2021 was $0.2 million and $11 thousand, respectively. The increase in interest income was due to the increase in average interest rates during the respective periods.

Other Income (Expense), Net

Other income (expense), net for the three months ended June 30, 2022 was $0.1 million. The other income of $0.1 million for the three months ended June 30, 2022 was primarily related to a grant received from a Massachusetts economic development and investment agency. Other income (expense), net for the three months ended June 30, 2021 was insignificant.

Revenue

Collaboration revenue decreased by $4.1 million to $5.9 million for the six months ended June 30, 2022, compared to $10.0 million for the three months ended June 30, 2021. The decrease in revenue was primarily due to the following:

an increase in the expected remaining performance period of the 2018 Roche Agreement at the end of 2021, resulting in a longer period over which revenue is recognized in 2022 as compared to the same period in 2021.
a decrease in the number of performance obligations for which revenue is being recognized. During the six months ended June 30, 2021, we recognized revenue of $0.8 million under the 2017 Roche Agreement whereas during the six months ended June 30, 2022, we recognized no revenue under this agreement as the performance obligations were fully satisfied.

Grant revenue increased by $0.2 million. We were awarded a government grant by the NIH at the end of the first quarter of 2022 and began performing services under this grant during the second quarter of 2022.

an increase of $0.4 million in professional, consultant and patent related costs due to higher, legal, recruiting and public relations costs.
an increase of $0.2 million in facility related and other costs primarily due to higher operational costs.

Interest Income

Interest income for the six months ended June 30, 2022 and 2021 was $0.2 million and $20 thousand, respectively. The increase in interest income was due to the increase in average interest rates during the respective periods.

Other Income (Expense), Net

Other income (expense), net for the six months ended June 30, 2022 was $0.1 million. The other income of $0.1 million for the six months ended June 30, 2022 was primarily related to a grant received from a Massachusetts economic development and investment agency. Other income (expense), net for the six months ended June 30, 2021 was insignificant.

 

Liquidity and Capital Resources

Since our inception, we have incurred significant operating losses. We have not yet commercialized any of our product candidates and we do not expect to generate revenue from sales of any product candidates for the next several years, if at all. Through June 30, 2022, we have funded our operations primarily with payments received in connection with collaboration agreements, proceeds from equity and debt financing, most recently, with proceeds from our IPO, Follow-On Offering and our at-the market offering facility with Jefferies LLC ("ATM Facility"). During the three and six months ended June 30, 2022, we raised $3.1 million, under the ATM Facility, pursuant to which we sold 958,663 shares of our common stock. See Note 1 to our consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q for further information on the ATM Facility. As of June 30, 2022, we had cash and cash equivalents of $105.6 million.

Operating Activities

During the six months ended June 30, 2022, operating activities used $40.9 million of cash, primarily resulting from our net loss of $43.3 million and changes in our operating assets and liabilities of $7.4 million, partially offset by net non-cash charges of $9.7 million. Net cash used by changes in our operating assets and liabilities for the six months ended June 30, 2022 consisted primarily of a $5.9 million decrease in deferred revenue, a $4.8 million decrease in operating lease liabilities, a $0.4 million increase in prepaid expenses and other current assets, a $2.9 million increase in accrued expenses, all of which were partially offset by a $3.0 million decrease in accounts receivable. The decrease in deferred revenue during the six months ended June 30, 2022 was due to the revenue we recognized in that same period under the 2018 Roche Agreement.

During the six months ended June 30, 2021, operating activities used $40.2 million of cash, primarily resulting from our net loss of $34.5 million and changes in our operating assets and liabilities of $14.7 million, partially offset by net non-cash charges of $8.9 million. Net cash used by changes in our operating assets and liabilities for the six months ended June 30, 2021 consisted primarily of a $9.8 million decrease in deferred revenue, a $4.6 million decrease in operating lease liabilities, a $2.0 million decrease in accrued expenses and a $0.4 million increase in prepaid expenses and other current assets, all of which were partially offset by a $1.9 million decrease in accounts receivable. The decrease in deferred revenue during the six months ended June 30, 2021 was due to the revenue we recognized in that same period under the 2018 Roche Agreement.

In all periods presented, other changes in prepaid expenses and other current assets, accounts receivable, accounts payable, accrued expenses and other liabilities not described above were generally due to growth in our business, the advancement of our research programs and the timing of vendor invoicing and payments. In all periods presented, decreases in operating lease liabilities were primarily due to our recurring payments made under recorded operating lease liabilities, including those arising from embedded leases.

Investing Activities

During the six months ended June 30, 2022 and 2021, net cash used in investing activities was $0.3 million and $0.5 million, respectively, consisting of purchases of property and equipment.

The purchases of property and equipment in each period were primarily for equipment purchases and leasehold improvements related to the expansion of our research and development activities and the growth of our business.

Financing Activities

During the six months ended June 30, 2022, net cash provided by financing activities was $3.2 million consisting of proceeds from the ATM Facility, employee stock purchase plan issuances, and stock option exercises during the period.

During the six months ended June 30, 2021, net cash provided by financing activities was $55.5 million, consisting of net proceeds from the Follow-on Offering in February 2021, of $56.4 million, in addition to proceeds of $1.0 million from stock option exercises during the period, offset by the payment of $1.9 million of IPO and Follow-on Offering costs.

Funding Requirements

We expect that our expenses will increase substantially in connection with our ongoing activities, particularly as we advance the preclinical activities and clinical trials for our product candidates in development. The timing and amount of our operating and capital expenditures will depend largely on:

the timing and progress of preclinical and clinical development activities, including geographic expansion of our clinical sites into Europe and Asia;
the commencement, enrollment or results of the planned clinical trials of our product candidates or any future clinical trials we may conduct, or changes in the development status of our product candidates;

25


Table of Contents

the timing and outcome of regulatory review of our product candidates;
our decision to initiate a clinical trial, not to initiate a clinical trial or to terminate an existing clinical trial as well as Roche’s decision whether to exercise its options;
changes in laws or regulations applicable to our product candidates, including but not limited to clinical trial requirements for approvals;
adverse developments concerning our manufacturers and other third-party providers;
our ability to obtain materials to produce adequate product supply for any approved product or inability to do so at acceptable prices;
our ability to establish collaborations if needed;
the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we obtain marketing approval;
the legal patent costs involved in prosecuting patent applications and enforcing patent claims and other intellectual property claims;
additions or departures of key scientific or management personnel;
unanticipated serious safety concerns related to the use of our product candidates;
the terms and timing of any collaboration, license or other arrangement, including the terms and timing of any milestone payments thereunder; and
the severity, duration and impact of the COVID-19 pandemic and macroeconomic conditions, which may adversely impact our business.

We believe that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2023. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, existing stockholders' interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, including due to adverse macroeconomic conditions such as rising interest rates, we would be required to delay, scale back or discontinue our research, product development or future commercialization efforts, or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Contractual Obligations and Commitments

There have been no material changes to our contractual obligations from those described in our 2021 Form 10-K. For additional information, see Note 8 and 9 to our condensed consolidated financial statements appearing in this Quarterly Report on Form 10-Q.

Critical Accounting Policies and Significant Judgments and Estimates

Our financial statements are prepared in accordance with generally accepted accounting principles in the United States. The preparation of our financial statements and related disclosures requires us to make estimates, assumptions and judgments that affect the reported amount of assets, liabilities, revenue, costs and expenses, and related disclosures. Our critical accounting policies are described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Significant Judgments and Estimates” in our 2021 Form 10-K. If actual results or events differ materially from the estimates, judgments and assumptions used by us in applying these policies, our reported financial condition and results of operations could be materially affected. There have been no significant changes to our critical accounting policies from those described in the 2021 Form 10-K.

Recently Issued Accounting Pronouncements

A description of recently issued accounting pronouncements that may potentially impact our financial position, results of operations or cash flows is disclosed in Note 2 to our condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

Emerging Growth Company Status

The Jumpstart Our Business Startups Act of 2012 permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. 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 will adopt the new or revised standard at the time private companies adopt the new or revised standard and will do so until such time that we either (i) irrevocably elect to “opt out” of such extended transition period or (ii) no longer qualify as an emerging growth company. We may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

As of June 30, 2022, we had cash and cash equivalents of $105.6 million, which consisted of cash and money market funds. Interest income is sensitive to changes in the general level of interest rates; however, due to the nature of these balances, an immediate 10% change in interest rates would not have a material effect on the fair market value of our cash and cash equivalents.

We are not currently exposed to significant market risk related to changes in interest rates or foreign currency exchange rates. Our operations may be subject to fluctuations in foreign currency exchange rates in the future.

We do not believe that inflation has had a material effect on our business, financial condition, or results of operations. Our operations may be subject to inflation in the future.

Item 4. Controls and Procedures.

Limitations on Effectiveness of 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 management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Principal Executive Officer and Principal Financial Officer, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934). Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2022.

Changes in Internal Control over Financial Reporting

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the three months ended June 30, 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On October 29, 2020, the SEC declared effective our registration statement on Form S-1 (File No. 333-249422), as amended, filed in connection with our IPO, or the Registration Statement. Pursuant to the Registration Statement, we registered the offer and sale of 5,073,529 shares of our common stock with a proposed maximum aggregate offering price of approximately $91.3 million. On November 3, 2020, we issued and sold 4,411,765 shares of our common stock at a price to the public of $16.00 per share. Upon completion of the IPO on November 3, 2020, we received net proceeds of approximately $65.6 million, after deducting underwriting discounts and commissions, but before deducting offering costs payable by us, which were $2.6 million. On November 12, 2020, in connection with the full exercise of the over-allotment option granted to the underwriters of our IPO, we issued and sold 661,764 additional shares of common stock at a price of $16.00 per share, generating additional net proceeds of $9.8 million after deducting underwriting discounts of $0.7 million.

As of June 30, 2022, we estimate that we have used 100% of the net proceeds for advancing the clinical development of our product candidates, development of additional product candidates as well as for working capital and general corporate purposes. There were no material changes in the use of the net proceeds from our IPO as described in our final prospectus relating to the Registration Statement, filed with the SEC on October 30, 2020 pursuant to Rule 424(b)(4).
