(Amounts in thousands, except share and per share data)

1. Nature of the Business
Surface Oncology, Inc. (the “Company” or “Surface”) is a clinical-stage immuno-oncology company focused on using its specialized knowledge of the biological pathways critical to the immunosuppressive tumor microenvironment (“TME”) for the development of next-generation cancer therapies. Surface was incorporated in April 2014 under the laws of the State of Delaware.
The Company is subject to risks common to early-stage companies in the biotechnology industry including, but not limited to, development by competitors of new technological innovations, protection of proprietary technology, dependence on key personnel, compliance with government regulations and the ability to obtain additional financing to fund operations. 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 infrastructure and extensive compliance-reporting capabilities. Even if the Company’s development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.
On May 22, 2020, the Company entered into a Capital on Demand™ Sales Agreement (the “2020 Sales Agreement”) with JonesTrading Institutional Services LLC (“JonesTrading") to issue and sell shares of the Company’s common stock of up to $50,000 in gross proceeds, from time to time during the term of the 2020 Sales Agreement, through an “at-the-market” equity offering program under which JonesTrading acted as the Company’s agent and/or principal (the “2020 ATM Facility”). The 2020 ATM Facility provided that JonesTrading was entitled to compensation for its services in an amount of up to 3.0% of the gross proceeds of any shares sold under the 2020 ATM Facility. The Company had no obligation to sell any shares under the 2020 ATM Facility and had the right, at any time, to suspend solicitation and offers under the 2020 Sales Agreement. In the three and nine months ended September 30, 2021, the Company sold 69,785 and 2,303,545 shares of common stock, at-the-market, under the 2020 Sales Agreement, resulting in net proceeds of approximately $497 and $19,479, respectively. The Company did not sell any shares of common stock at-the-market under the 2020 Sales Agreement in 2020. On August 5, 2021, the Company closed the 2020 ATM Facility.
On August 5, 2021, the Company entered into an amendment to the 2020 Sales Agreement (as amended, the “Amended Sales Agreement”) with JonesTrading, which amended the 2020 Sales Agreement to allow the issuance and sale of up to $80,000 in gross proceeds, from time to time during the term of the Amended Sales Agreement, through an “at-the-market” equity offering program under which JonesTrading will act as the Company’s sales agent (the “2021 ATM Facility”). The 2021 ATM Facility provides that JonesTrading will continue to be entitled to compensation for its services in an amount of up to 3.0% of the gross proceeds of any shares sold under the 2021 ATM Facility. The Company has no obligation to sell any shares under the Amended Sales Agreement and may, at any time, suspend solicitation and offers under the 2021 ATM Facility. In the three and nine months ended September 30, 2022, the Company sold 4,778,248 and 13,141,434 shares of common stock, at-the-market under the Amended Sales Agreement, resulting in net proceeds of approximately $8,666 and $31,331, respectively. Since August 5, 2021, the Company has sold 14,575,061 shares of common stock at-the-market under the 2021 ATM Facility for net proceeds of $41,377.
The Company’s 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. The Company has primarily funded its operations with proceeds from private and public sales of its securities, proceeds from a collaboration agreement with Novartis Institutes for Biomedical Research, Inc. (“Novartis”), proceeds from a license agreement with GlaxoSmithKline Intellectual Property (No. 4) Limited (“GSK”) and issuance of a term loan with K2 Health Ventures LLC (“K2HV”). The Company has a history of incurring losses and negative cash flows from operations. As of September 30, 2022, the Company had an accumulated deficit of $182,997.
The Company expects that its operating losses and negative cash flows will continue for the foreseeable future. As of November 2, 2022, the issuance date of this Quarterly Report on Form 10-Q, the Company expects that its cash, cash equivalents and marketable securities will be sufficient to fund its operating expenses, debt service obligations and capital expenditure requirements for at least the next 12 months. The future viability of the Company beyond that date is dependent on its ability to raise additional capital to finance its operations.

SURFACE ONCOLOGY, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
(Amounts in thousands, except share and per share data)
The Company will seek additional funding through public financings, debt financings, collaboration agreements, strategic alliances and 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. If the Company is unable to obtain funding, the Company could be required to delay, reduce, or eliminate research and development programs, product portfolio expansion, or future commercialization efforts, which could adversely affect its business prospects.
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.
The ongoing global outbreak of the novel coronavirus disease and its variants (collectively, “COVID-19”) and significant governmental and related measures implemented or reimplemented to help control the spread of the virus have impacted and could materially and adversely impact the Company's business, results of operations and financial condition. The Company is continues to monitor the impact of the COVID-19 pandemic and take steps to identify and help minimize its adverse impact on, and risks to, the Company's business, although there can be no assurance that the Company will be able to identify all such steps or that any identified steps will be effective. Although COVID-19 has not had a material adverse impact on the Company’s operations and its clinical and preclinical programs, the extent to which COVID-19 will ultimately impact the Company’s business, results of operations or financial condition will depend on future developments which are highly uncertain and cannot be predicted with confidence, such as the duration of COVID-19 and the severity of its variants or the effectiveness over time of the measures implemented or reimplemented to help contain the pandemic or mitigate against its impact, among others. Certain of the Company’s third-party service providers have experienced shutdowns or other business disruptions. As a result, the Company’s ability to conduct its business in the manner and on the timelines presently planned could be materially or negatively affected, which could have a material adverse impact on the Company’s business, results of operations and financial condition.
2. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its wholly owned subsidiary, Surface Securities Corporation, a Massachusetts corporation, after elimination of all intercompany accounts and transactions.
 
The accounting policies followed in the preparation of the interim condensed consolidated financial statements are consistent in all material respects with those presented in Note 2 to the financial statements included in the Company’s Annual Report on Form 10-K, filed with the Securities and Exchange Commission (the “SEC”) on March 2, 2022.
Use of Estimates
The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, revenue recognition and the accrual of research and development expenses. Estimates are periodically reviewed in light of changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from the Company’s estimates.

Unaudited Interim Financial Information
The accompanying condensed consolidated financial statements are unaudited. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of September 30, 2022 and the results of its operations and its cash flows for the three and nine months ended September 30, 2022 and 2021. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2022 and 2021 are also unaudited. The condensed balance sheet at December 31, 2021, was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. The results for the three and nine months ended September 30, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022, any other interim periods, or any future year period.
Recently Issued Accounting Pronouncements
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 may result in earlier recognition of credit losses. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which narrowed the scope and changed the effective date for non-public entities for ASU 2016-13. The FASB subsequently issued supplemental guidance within ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief (“ASU 2019-05”). ASU 2019-05 provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. This standard will be effective for the Company on January 1, 2023. The Company is currently evaluating the potential impact that this standard may have on its condensed consolidated financial statements and related disclosures.
Other accounting standards that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s financial statements upon adoption.

These represent a Level 2 measurement within the fair value hierarchy. During the nine months ended September 30, 2022 and 2021, there were no transfers between Level 1, Level 2 and Level 3.
5. Collaboration and License Agreements
Novartis Agreement
In January 2016, the Company entered into a collaboration agreement with Novartis, which was subsequently amended in May 2016, July 2017, September 2017, and October 2018 (as amended, the “Novartis Agreement”). Pursuant to the Novartis Agreement, the Company granted Novartis a worldwide exclusive license to research, develop, manufacture and commercialize antibodies that target cluster of differentiation 73 (“CD73”). In addition, the Company initially granted Novartis the right to purchase exclusive option rights (each an “Option”) for up to four specified targets (each an “Option Target”) including certain development, manufacturing, and commercialization rights, pursuant to which, Novartis initially had the right to exercise up to three purchased Options. Accordingly, Novartis had the ability to exclusively license the development, manufacturing and commercial rights for up to four targets (inclusive of CD73). Through September 30, 2022, the Company had received an aggregate of $150,000 from Novartis in upfront payments, milestone payments, and option purchase payments.As of January 2020, there were no Options remaining for purchase and exercise, and accordingly the Company’s performance obligations under the Novartis Agreement ended. Under the Novartis Agreement, the Company is currently entitled to potential development milestones of $325,000 and sales milestones of $200,000, as well as tiered royalties on annual net sales by Novartis ranging from high single-digit to mid-teens percentages upon the successful commercialization of NZV930 (formerly SRF373). Due to the uncertainty of pharmaceutical development and the historical failure rates generally associated with drug development, the Company may not receive any milestone payments or any royalty payments under the Novartis Agreement.

Termination
Unless terminated earlier, the Novartis Agreement will continue in effect until neither the Company nor Novartis is researching, developing, manufacturing or commercializing NZV930. Novartis may terminate the Novartis Agreement for any or no reason upon prior notice to the Company within a specified time period. Either party may terminate the Novartis Agreement in full if an undisputed material breach is not cured within a certain period of time or upon notice of insolvency of the other party. To the extent Novartis terminates for convenience, or the Company terminates for Novartis’ uncured material breach, Novartis will grant the Company, on mutually agreeable financial terms, an exclusive, worldwide, irrevocable, perpetual and royalty-bearing license with respect to intellectual property controlled by Novartis that is reasonably necessary to research, develop, manufacture or commercialize NZV930.
Revenue Recognition – Collaboration Revenue – Related Party
In determining the appropriate amount of revenue to be recognized under ASC 606, the Company performed the following steps: (i) identified the promised goods or services in the contract; (ii) determined whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.
Under ASC 606, the Company recognized revenue using the cost-to-cost method, which it believes best depicts the transfer of control to the customer. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation. Under this method, revenue will be recorded as a percentage of the estimated transaction price based on the extent of progress towards completion. Under ASC 606, the estimated transaction price will include variable consideration. The Company does not include variable consideration to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will occur when any uncertainty associated with the variable consideration is resolved. The estimate of the Company’s measure of progress and estimate of variable consideration to be included in the transaction price will be updated at each reporting date as a change in estimate. The amount related to the unsatisfied portion will be recognized as that portion is satisfied over time.
Under ASC 606 the Company accounted for (i) the license it conveyed with respect to CD73; and (ii) its obligations to perform research on CD73 and other specified targets as a single performance obligation under the Novartis Agreement. Novartis’ right to purchase exclusive options to obtain certain development, manufacturing and commercialization rights would have been accounted for separately as they did not represent material rights, based on the criteria of ASC 606. Upon the exercise of any purchased option by Novartis, the contract promises associated with an Option Target would have used a separate cost-to-cost model for purposes of revenue recognition under ASC 606.
The Company did not recognize any revenue relating to the Novartis Agreement during the three and nine months ended September 30, 2022 and 2021 as it does not have any remaining performance obligations under the agreement.

GSK Agreement
In December 2020, the Company entered into a license agreement with GSK, which was subsequently amended in August 2021 (as amended, the “GSK Agreement”). Pursuant to the GSK Agreement, the Company granted GSK a worldwide exclusive, sublicensable license to develop, manufacture and commercialize antibodies that target the antibody GSK4381562 (formerly SRF813), targeting CD112R, also known as PVRIG (the “Licensed Antibodies”). GSK is responsible for the development, manufacturing and commercialization of the Licensed Antibodies and a joint development committee was formed to facilitate information sharing between the Company and GSK. GSK is responsible for all costs and expenses of such development, manufacturing and commercialization and is obligated to provide the Company with updates on its development, manufacturing and commercialization activities through the joint development committee. Under the terms of the GSK Agreement, GSK made a one-time upfront payment of $85,000 and was required to make additional payments to the Company for supply services and transition services of $4,314 and $950, respectively. In November 2021, GSK notified the Company it received clearance from the FDA for GSK4381562 to proceed into a first-in-human clinical trial, and as a result, the Company’s performance obligations under the GSK Agreement ended. In March 2022, the Company earned a $30,000 milestone payment from GSK upon the dosing of the first patient in the Phase 1 trial of GSK4381562, which it received in the second quarter 2022. The Company is currently eligible to receive up to $60,000 in clinical and $155,000 in regulatory milestones. In addition, the Company may receive up to $485,000 in sales milestone payments. The Company is also eligible to receive royalties on global net sales of any approved products based on the licensed antibodies, ranging in percentages from high single digits to mid-teens. Due to the uncertainty of pharmaceutical development and the historical failure rates generally associated with drug development, the Company may not receive any milestone payments or any royalty payments under the GSK Agreement.
Termination
Unless terminated earlier, the GSK Agreement expires on a licensed product-by-licensed product and country-by-country basis on the later of ten years from the date of first commercial sale or when there is no longer a valid patent claim or regulatory exclusivity covering such licensed product in such country. Either party may terminate the GSK Agreement for an uncured material breach by the other party or upon the bankruptcy or insolvency of the other party. GSK may terminate the GSK Agreement for its convenience. The Company may terminate the GSK Agreement if GSK institutes certain actions related to the licensed patents or if GSK ceases development activities, other than for certain specified technical or safety reasons. In the event of termination, the Company would regain worldwide rights to the terminated program.
Revenue Recognition – License-Related Revenue
In determining the appropriate amount of revenue to be recognized under ASC 606, the Company performed the following steps: (i) identified the promised goods or services in the contract; (ii) determined whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.
The Company assessed the GSK Agreement in accordance with ASC 606 and concluded that GSK is a customer. The Company identified the following promises under the contract: (i) a worldwide exclusive, sublicensable license to develop, manufacture and commercialize the Licensed Antibodies; (ii) supplying Licensed Antibodies until an IND is accepted by a regulatory authority (iii) transition services until an IND is accepted by a regulatory authority; and (iv) participation on the joint development and joint patent committees. The Company assessed the above promises and determined that the worldwide exclusive, sublicensable license to develop, manufacture and commercialize the Licensed Antibodies is considered functional intellectual property and distinct from other promises under the contract. This functional license is distinct in the context of the GSK Agreement as GSK can benefit from the license on its own or together with other readily available resources. In addition, the supply and transition services are not complex or specialized, could be performed by another qualified third party, are not expected to significantly modify or customize the license to GSK4381562 (formerly SRF813), and are expected to be performed only for a short period of time. The Company determined that the impact of participation on the joint development and joint patent committees was insignificant and had an immaterial impact on the accounting model. Based on these assessments, the Company identified three distinct performance obligations at the outset of the GSK Agreement.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
(Amounts in thousands, except share and per share data)
The Company determined the transaction price of the GSK Agreement, under ASC 606, to be $90,264, consisting of the upfront payment of $85,000 plus $4,314 for supply of the Licensed Antibodies and $950 for the transition services. The Company evaluated how much variable consideration related to clinical and regulatory milestones to include in the transaction price using the most likely amount approach and concluded that no amount should be included in the transaction price due to the high degree of uncertainty and risk associated with these potential payments. The Company also determined that royalties and sales milestones relate solely to the licenses of intellectual property and are therefore excluded from the transaction price under the sales- or usage-based royalty exception of ASC 606. Revenue related to these royalties and sales milestones will only be recognized when the associated sales occur, and relevant thresholds are met.
As noted above, the Company identified three performance obligations in the GSK Agreement: (i) the delivery of the worldwide exclusive, sublicensable license to develop, manufacture and commercialize the Licensed Antibodies; (ii) supply of Licensed Antibodies until an IND is accepted by a regulatory authority; and (iii) transition services until an IND is accepted by a regulatory authority. The selling price of each performance obligation in the GSK Agreement was determined based on the Company’s standalone selling price with the objective of determining the price at which it would sell such an item if it were to be sold regularly on a standalone basis. The Company recognized revenue for the license performance obligation upon transfer of the license to GSK. As control of the license was transferred on the effective date of December 16, 2020, and GSK could begin to use and benefit from the license, the Company recognized $85,000 of license-related revenue during the year ended December 31, 2020. The Company recognized the costs allocated to supply services and transition services over time as the Company transferred control of these services and GSK received and consumed the benefit as the Company performed the services. The Company re-evaluated the transaction price at the end of each reporting period and as uncertain events were resolved, or other changes in circumstances occurred, adjusted its estimate of the transaction price as necessary. The transaction and supply services were completed in November 2021.
In November 2021, GSK notified the Company it received clearance from the FDA for GSK4381562 to proceed into a first-in-human clinical trial and as a result the Company's performance obligations under the GSK Agreement ended.
In March 2022, GSK notified the Company it had dosed the first patient in its in Phase 1 study of GSK4381562 in patients with solid tumors. As a result of this Phase 1 study initiation, the first clinical milestone under the GSK Agreement was achieved. The Company concluded the variable consideration associated with this milestone was no longer constrained and recognized $30,000 in license-related revenue for the nine months ended September 30, 2022, as it had no further performance obligations associated with the milestone. The Company did not recognize license-related revenue under the GSK Agreement in the three months ended September 30, 2022.
During the three and nine months ended September 30, 2022, the Company did not recognize any license-related revenue related to the transition services or supply services, as the Company's performance obligations under the GSK Agreement had ended. During the three and nine months ended September 30, 2021, the Company recognized $48 and $709 of license-related revenue related to the transition services, respectively, and recognized $344 and $1,823 of license-related revenue related to the supply services, respectively, which represents the costs incurred for the manufacturing and transition services that were performed.
For the three and nine months ended September 30, 2022 and 2021, the Company recognized the following totals of license-related revenue:
