Item 8.01

Other Events.

As previously disclosed on June 15, 2023, Surface Oncology, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Coherus BioSciences, Inc., a Delaware corporation (“Parent”), Crimson Merger Sub I, Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub I”), and Crimson Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of Parent (“Merger Sub II” and together with Merger Sub I, the “Merger Subs”). On July 26, 2023, each of the Company and Parent filed the definitive version of the proxy statement with the United States Securities and Exchange Commission (the “SEC”) in connection with the Mergers (the “Proxy Statement”).

Minimum Net Cash Requirement

Pursuant to the Merger Agreement, and subject to the terms and conditions set forth therein, Merger Sub I will merge with and into the Company (the “First Merger”), with the Company surviving such First Merger as a wholly owned subsidiary of Parent, and, as part of the same overall transaction, promptly after the First Merger, the surviving corporation of the First Merger will merge with and into Merger Sub II (the “Second Merger” and together with the First Merger, the “Mergers”), with Merger Sub II surviving the Second Merger (the “Surviving Entity”).

Under the terms of the Merger Agreement, the consummation of the Mergers is subject to the satisfaction or waiver of certain customary closing conditions of the respective parties, including, among other closing conditions, that the Company Net Cash (as defined in the Merger Agreement), calculated as of the applicable dates of determination under the Merger Agreement (the “Company Net Cash Determination Dates”), shall be no less than $19,600,000 (or such lower amount as may be consented to in writing by Parent prior to the closing of the First Merger) (the “Minimum Net Cash Condition”). In accordance with the terms of the Merger Agreement, the Company delivered to Parent a schedule (the “Net Cash Schedule”) setting forth the Company’s good faith estimated calculation of the Company Net Cash as of the applicable Company Net Cash Determination Dates (the “Net Cash Calculation”). On August 24, 2023, Parent notified the Company in writing that it has no objections to the Net Cash Calculation as set forth in the Net Cash Schedule and such Net Cash Calculation is thus deemed to have been determined for purposes of the Merger Agreement and to represent the Company Net Cash as of the applicable Company Net Cash Determination Dates. Accordingly, the Minimum Net Cash Condition is deemed to have been satisfied as of the closing of the Mergers.

The consummation of the Mergers remains subject to the satisfaction (or written waiver by each of the Company, Parent and the Merger Subs if permissible by law) of other closing conditions, including, but not limited to, the approval of the adoption of the Merger Agreement by holders of at least a majority of the Company’s outstanding common stock. The parties expect that the Mergers will be consummated in September 2023.

Litigation Matters

Since the filing of the Proxy Statement, three complaints have been filed by purported stockholders of the Company as individual actions against the Company and the members of its Board of Directors. Two complaints have been filed in the United States District Court for the Southern District of New York, captioned Guentter v. Surface Oncology, Inc. et al., Case No. 1:23-cv-06687 (filed July 31, 2023) and Finger v. Surface Oncology, Inc. et al., Case No. 1:23-cv-7180 (filed August 14, 2023), respectively, and one complaint has been filed in the United States District Court for the District of Delaware, captioned Lang v. Surface Oncology, Inc. et al., Case No. 1:23-cv-897 (filed August 15, 2023). The foregoing complaints are referred to as the “Filed Merger Actions.”

Furthermore, on August 3, 2023, and August 23, 2023, two purported stockholders of the Company sent draft complaints asserting claims against the Company and the members of its Board of Directors. The foregoing draft complaints are referred to as the “Draft Merger Actions” and the Filed Merger Actions and Draft Merger Actions are referred to collectively as the “Merger Actions.”

The Merger Actions allege that the Proxy Statement misrepresents and/or omits certain purportedly material information. The Merger Actions assert claims for violations of Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder against the Company and its Board of Directors, and violations of Section 20(a) of the Exchange Act against the Company’s Board of Directors.

Additionally, on July 24, 2023, July 25, 2023, August 3, 2023, August 17, 2023, and August 18, 2023, six purported stockholders of the Company sent demand letters alleging similar insufficiencies in the disclosures in the Proxy Statement in violation of Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, and Section 20(a) of the Exchange Act (such letters, the “Demands” and collectively with the Merger Actions, the “Litigation Matters”).

The purported stockholders in the Litigation Matters seek various remedies including, among other things, an order enjoining the consummation of the Mergers, requiring the defendants to file an amended Proxy Statement, rescinding the Mergers in the event they are consummated or granting rescissory damages, and awarding costs of the action, including plaintiff’s attorneys’ fees and experts’ fees, and other relief the court may deem just and proper.

The Companyand Parent believe that the claims asserted in the Litigation Matters are without merit. The Companyand Parent deny that any further disclosure beyond that already contained in the Proxy Statement is required under applicable law to supplement the Proxy Statement, as claimed in the Litigation Matters. Nonetheless, to moot these purported stockholders’ unmeritorious claims, avoid the risk that litigation may delay or otherwise adversely affect the consummation of the Mergers and to minimize the expense of defending against the Litigation Matters, the Companyand Parent are making the following supplemental disclosures to the Proxy Statement. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the supplemental disclosures set forth herein. To the contrary, the Companyand Parent specifically deny all allegations in the Litigation Matters that any additional disclosure was or is required.

Supplemental Disclosures

This supplemental information to the Proxy Statement should be read in conjunction with the Proxy Statement, which should be read in its entirety. All page references in the information below are to pages in the Proxy Statement, and all terms used but not defined below shall have the meanings set forth in the Proxy Statement. To the extent the following information differs from or conflicts with the information contained in the Proxy Statement, the information set forth below shall be deemed to supersede the respective information in the Proxy Statement. New text within the amended and supplemented language from the Proxy Statement is indicated in bold and underlined text (e.g., bold, underlined text), and deleted text within the amended and supplemented language from the Proxy Statement is indicated in bold and strikethrough text (e.g., bold, strikethrough text).

The disclosure in the section entitled “Background of the Mergers,” beginning on page 62 of the Proxy Statement, is hereby amended and supplemented as follows:

The following text is added after the first sentence of the second full paragraph on page 64 of the Proxy Statement:

As directed by the Surface board of directors, Surface management conducted the strategic review of potential Group A and Group B companies, and had preliminary discussions with certain of these companies to ascertain interest in a potential transaction with Surface. As part of this strategic review, 23 Group A companies (including Coherus as described below) and nine Group B companies (including Company A (as defined below)) executed a mutual confidentiality agreement with Surface, which did not contain standstill obligations.

The following text is added to the third full paragraph on page 66 of the Proxy Statement:

During February and March 2023, members of Surface management, as authorized by the Surface board of directors, had preliminary discussions with another publicly traded oncology company (“Company A”) regarding a potential business combination transaction. Company A was already subject to an existing mutual confidentiality agreement with Surface executed in 2022 that did not contain a standstill provision.

The disclosure in the last paragraph on page 66 of the Proxy Statement which ends on page 67 of the Proxy Statement is amended as follows:

During the period beginning on March 1, 2023 and continuing until April 14, 2023, as authorized by the Surface board of directors, representatives of Wedbush and Surface management contacted a broad selection of 217 private and public companies in the life sciences industry. Included in these 217 companies, representatives of Wedbush contacted Company A, Coherus and two other Group B companies (“Company B” and “Company C”) and. Surface management also contacted certain Group A companies it had previously contacted in 2022 to ascertain interest in a strategic transaction or acquisition at that time, of which there was none.

The disclosure in the first sentence of the first full paragraph on page 67 of the Proxy Statement is amended as follows:

Of the 217 companies: (i) 183 declined interest for a variety of reasons or did not respond to the outreach; (ii) 31 of these companies had management calls or meetings with Surface between March 14 and April 21, 2023; (iii) 27 companies submitted a non-binding indication of interest; (iv) seven companies expressed interest but did not submit a non-binding indication of interest; and (v) 41 executed a mutual confidentiality agreement with Surface. All of these mutual confidentiality agreements included customary standstill obligations (including a “don’t ask / don’t waive” provision) that automatically terminated upon Surface’s announcement of the execution of a definitive agreement with a third party to effect a change of control of Surface, except that (1) two mutual confidentiality agreements that did not include a “don’t ask / don’t waive” provision, (2) the mutual confidentiality agreement with Company E (as defined below) provided that Company E can submit a confidential proposal to Surface at any time and (3) the mutual confidentiality agreement with Company A executed in 2022 that did not contain a standstill provision as described above.

The following text is added after the second sentence of the third full paragraph on page 67 of the Proxy Statement:

Carsten Brunn (Chair) and David Grayzel, non-management independent directors, and J. Jeffery Goater, a non-management director, have significant strategic transaction experience and were appointed to the Transaction Committee. The Transaction Committee was authorized to explore strategic alternatives to enhance value to Surface’s common stockholders and granted the powers to (a) consider and evaluate all proposals that might be received by Surface in connection with a possible sale or other business transaction or series of transactions involving all or substantially all of Surface’s equity or assets on a consolidated basis, through any form of transaction, including, without limitation, merger, stock purchase, asset purchase, recapitalization, reorganization, going-private transaction, “reverse merger,” consolidation, amalgamation, spin-out of assets, licensing, collaboration of all or certain assets, dividends or distribution of assets or rights to assets or future payments, debt or equity financing, or other transaction (any of the foregoing, a “Transaction”), (b) participate in and direct the negotiation of the material terms and conditions of any such Transaction, (c) consider any alternatives to any such Transaction, including without limitation, Surface continuing to operate as an independent company, (d) recommend to the Surface board of directors the advisability of entering into a definitive agreement (and any ancillary agreements relating thereto) with respect to any such Transaction, or the advisability of pursuing any other alternative, in each case subject to applicable law, and (e) perform any other activities or responsibilities incidental to the foregoing, including keeping the Surface board of directors apprised of the status of any potential Transaction.

The following text is added after the second sentence of the fifth full paragraph on page 74 of the Proxy Statement:

Representatives of Goodwin provided an update on the negotiation of the Merger Agreement and the CVR Agreement. Wedbush was advised that, given the risks and uncertainties of drug development, there may not be any payments at all or during the period required by the CVR Agreement for the holders of Surface common stock to receive the payments due pursuant to the CVR and to accordingly ascribe no value to the CVRs.

The following text is added after the first sentence of the first full paragraph on page 76 of the Proxy Statement:

Also at the meeting, representatives of Wedbush reviewed Wedbush’s preliminary financial analyses of Surface, Coherus, and certain financial terms of the Merger Agreement. Wedbush did not consider any financial projections or analyses other than the Liquidation Analysis due to Surface’s lack of anticipated revenue for the foreseeable future, and Surface management did not furnish Wedbush with any such materials.

The disclosure in the section entitled “Opinion of Surface’s Financial Advisor,” beginning on page 84 of the Proxy Statement, is hereby amended and supplemented as follows:

The following text is deleted from the second sentence of the last paragraph on page 86 of the Proxy Statement:

Surface has also agreed to pay Wedbush a success fee in an amount equal to 1% of the transaction value, subject to a minimum fee of $1,500,000, for its services as Surface’s exclusive strategic financial advisor, which fee is contingent upon consummation of the Mergers.

The disclosure under the subheading “Summary of Analyses” is hereby amended and supplemented by adding the following text after the first sentence of the first full paragraph after the first bullet point list on page 87 of the Proxy Statement:

Representatives of Wedbush and members of Surface’s management determined that a discounted cash flow analysis was not an appropriate indicator to measure the value of Surface because Surface did not anticipate any significant revenue for the foreseeable future. Surface management therefore did not furnish Wedbush with any financial projections or analyses for use in preparing its fairness opinion.

The disclosure under the subheading “Summary of Analyses” is hereby amended and supplemented by adding the following text to the third full paragraph after the first bullet point list on page 87 of the Proxy Statement:

At Surface’s instruction, Wedbush did not value the CVRs and assumed for purposes of its analysis that the CVRs had no value due to the risk that there may not be any payments at all or during the period required by the CVR Agreement for the holders of Surface common stock to receive the payments due pursuant to the CVR.

The following text is added after the last sentence of the fifth full paragraph on page 150 of the Proxy Statement:

Surface and Coherus have discussed the potential for certain Surface executives to provide assistance to Coherus post-closing pursuant to consulting agreements. All such discussions occurred only after the execution and announcement of the Merger Agreement.

potential negative effects related to this announcement or the consummation of the proposed transaction on the market price of the Company’s or Parent’s common stock and/or the Company’s or Parent’s operating or financial results; the difficulty of predicting the timing or outcome of regulatory approvals or actions; the risks that holders of the contingent value rights (“CVRs”) will not receive payments in respect of the CVRs; uncertainties as to the long-term value of Parent’s common stock, including the dilution caused by Parent’s issuance of additional shares of common stock in connection with the proposed transaction; unknown liabilities related to the Company or Parent;

risks related to global as well as local political and economic conditions, including interest rate and currency exchange rate fluctuations; potential delays or failures related to research and/or development of the Company’s or Parent’s programs or product candidates; risks related to any loss of the Company’s or Parent’s patents or other intellectual property rights; any interruptions of the supply chain for raw materials or manufacturing for the Company’s or Parent’s product candidates, the nature, timing, cost and possible success and therapeutic applications of product candidates being developed by the Company, Parent and/or their respective collaborators or licensees; the extent to which the results from the research and development programs conducted by the Company, Parent, and/or their respective collaborators or licensees may be replicated in other studies and/or lead to advancement of product candidates to clinical trials, therapeutic applications, or regulatory approval; uncertainty of the utilization, market acceptance, and commercial success of the Company’s or Parent’s product candidates, and the impact of studies (whether conducted by the Company, Parent or others and whether mandated or voluntary) on any of the foregoing; unexpected breaches or terminations with respect to the Company’s or Parent’s material contracts or arrangements; risks related to competition for the Company’s or Parent’s product candidates; the Company’s or Parent’s ability to successfully develop or commercialize the Company’s or Parent’s product candidates; the Company’s, Parent’s, and their collaborators’ abilities to continue to conduct current and future developmental, preclinical and clinical programs; potential exposure to legal proceedings and investigations; risks related to changes in governmental laws and related interpretation thereof, including on reimbursement, intellectual property protection and regulatory controls on testing, approval, manufacturing, development or commercialization of any of the Company’s or Parent’s product candidates; unexpected increases in costs and expenses with respect to the potential transaction or the Company’s or Parent’s business or operations; and risks and uncertainties related to epidemics, pandemics or other public health crises and their impact on the Company’s and Parent’s respective businesses, operations, supply chain, patient enrollment and retention, preclinical and clinical trials, strategy, goals and anticipated milestones. While the foregoing list of factors presented here is considered representative, no list should be considered to be a complete statement of all potential risks and uncertainties. There can be no assurance that the Mergers or any other transaction described above will in fact be consummated in the manner described or at all. A more complete description of these and other material risks can be found in the Company’s and Parent’s respective filings with the SEC, including each of their Annual Reports on Form 10-K for the year ended December 31, 2022, subsequent Quarterly Reports on Form 10-Q and other documents that may be filed from time to
