Item 1.01

Entry into a Material Definitive Agreement.

On March 4, 2021, Five Prime Therapeutics, Inc., a Delaware corporation (the “Company” or “Five Prime”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Amgen Inc., a Delaware corporation (“Parent” or “Amgen”), and Franklin Acquisition Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Purchaser”).

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Parent has agreed to cause Purchaser to commence a cash tender offer (the “Offer”) to purchase all of the outstanding shares of common stock of the Company, par value $0.001 per share (the “Shares”), at a price of $38.00 per Share (the “Offer Price”), in cash, minus any applicable withholding taxes and without interest. Following the consummation of the Offer and subject to the terms and conditions of the Merger Agreement, Purchaser will be merged with and into the Company (the “Merger”) pursuant to Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”), with the Company continuing as the surviving corporation in the Merger and a wholly owned subsidiary of Amgen. At the effective time of the Merger, each Share (other than Shares validly tendered and irrevocably accepted for purchase pursuant to the Offer, Excluded Shares and Dissenting Shares (each as defined in the Merger Agreement)) will be converted into the right to receive an amount in cash equal to the Offer Price, without interest, minus any required withholding of taxes.

The Offer will initially remain open for 20 business days from the date of commencement of the Offer. If at the scheduled expiration time of the Offer any of the conditions to the Offer have not been satisfied (unless such condition is waivable by Purchaser or Parent and has been waived), Purchaser, at its discretion, may extend, and at the request of the Company, Purchaser will extend, the Offer to permit the satisfaction of all Offer conditions.

The obligation of Purchaser to accept for payment, and pay for, Shares validly tendered (and not validly withdrawn) pursuant to the Offer is subject to satisfaction or waiver, to the extent permitted under applicable legal requirements, of customary conditions, including (i) there being validly tendered and not validly withdrawn Shares that, considered together with all other Shares (if any) beneficially owned by Purchaser and its affiliates, represent one more Share than 50% of the total number of Shares outstanding at the expiration of the Offer, (ii) the accuracy of the Company’s representations and warranties (subject to customary materiality qualifiers), (iii) the Company’s compliance or performance in all material respects of its obligations, covenants and agreements it is required to comply with or perform at or prior to the expiration of the Offer, (iv) the absence, since the date of the Merger Agreement, of a Material Adverse Effect (as defined in the Merger Agreement) that is continuing, (v) the expiration or termination of the waiting period (or any extension thereof) applicable to the Offer under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and (vi) the absence of any law or order prohibiting the consummation of the Offer or the Merger.

The Merger Agreement includes certain representations, warranties and covenants of the Company, Parent and Purchaser, including certain restrictions with respect to the Company’s business between signing and consummation of the Merger. Parent and the Company also agreed to use their respective commercially reasonable efforts to take all actions, to file all documents and to do all things necessary, proper or advisable under applicable antitrust laws to consummate and make effective the transactions as soon as reasonably practicable, subject to certain limitations set forth in the Merger Agreement.

The Company has agreed to customary “no-shop” restrictions on its ability to solicit alternative acquisition proposals from third parties and engage in discussions or negotiations with third parties regarding alternative acquisition proposals. Notwithstanding these restrictions, the Company may under certain circumstances provide information to and engage in or otherwise participate in discussions or negotiations with third parties with respect to a bona fide written alternative acquisition proposal that the board of directors of the Company (the “Company Board”) has determined in good faith, after consultation with its financial advisor and outside legal counsel, constitutes a Superior Offer (as defined in the Merger Agreement) and that failure to take such action would reasonably be expected to constitute a breach of the Company Board’s fiduciary duties under applicable legal requirements. The Merger Agreement also requires that the Company Board recommend that the stockholders of the Company accept the Offer and tender their Shares to Purchaser pursuant to the Offer and not, among other things, (i) withdraw (or modify, amend or qualify in a manner adverse to Parent or Purchaser), or publicly propose to withdraw (or modify, amend or qualify in a manner adverse to Parent or Purchaser), the Company Board’s

recommendation, (ii) approve, recommend or declare advisable, or propose to approve, recommend or declare advisable, any alternative acquisition proposal, (iii) fail to include the Company Board’s recommendation in the Company’s Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9”) when filed with the U.S. Securities and Exchange Commission (the “SEC”) when disseminated to the Company’s stockholders, or (iv) approve, recommend or declare advisable, or propose to approve, recommend or declare advisable, or allow the Company to execute or enter into any contract with respect to any acquisition proposal (other than a confidentiality agreement). Notwithstanding these restrictions, the Company Board is permitted, subject to the terms and conditions set forth in the Merger Agreement, to change its recommendation and terminate the Merger Agreement to accept a Superior Offer or change its recommendation in response to a Change in Circumstance (as defined in the Merger Agreement), subject in each case to certain matching rights in favor of Parent.

The Merger Agreement contains certain termination rights for both the Company and Parent, including if (i) the consummation of the transactions has not occurred prior to December 4, 2021 (the “End Date”), (ii) if consummation of the Offer or the Merger is legally prohibited or permanently enjoined or (iii) if the Offer has been withdrawn or terminated in accordance with the terms of the Merger Agreement, provided that the terminating party’s material breach of any provision of the Merger Agreement is not the cause of the events specified in the foregoing subclauses (i) through (iii) occurring. The Merger Agreement may also be terminated by Parent if (i) the Company Board has effected a Company Adverse Change Recommendation (as defined in the Merger Agreement), (ii) the Company has entered into an agreement with respect to a Superior Offer, (iii) the Company Board fails to publicly reaffirm the Company Board’s recommendation upon request by Parent (subject to certain limitations), (iv) in the case of a tender offer or exchange offer, the Company Board fails to recommend in a Schedule 14D-9 the rejection by its stockholders of such tender offer or exchange offer, or (v) the Company has breached any representation, warranty or covenant that cannot be cured by the End Date or, if capable of being cured, has not been cured within 30 days following written notice, if such breach would cause certain of the conditions to closing to not be able to be satisfied. The Merger Agreement may also be terminated by the Company (i) subject to the terms and conditions set forth in the Merger Agreement, to accept a Superior Offer, (ii) if Parent or Purchaser has breached any representation, warranty or covenant that cannot be cured by the End Date or, if capable of being cured, has not been cured within 30 days following written notice, if such breach would reasonably be expected to prevent Parent or Purchaser from consummating the transactions, or (iii) in the event that Purchaser fails to commence the offer within the specified period (unless such failure to commence the tender offer is principally caused by the material breach of a covenant or obligation by the Company) or fails to purchase all Shares validly tendered (and not validly withdrawn) when required to do so under the Merger Agreement. Upon termination of the Merger Agreement (i) by the Company to accept a Superior Offer or (ii) by Parent following a Company Adverse Change Recommendation, the Company will be required to pay Parent a termination fee of $76,000,000. Under certain additional circumstances described in the Merger Agreement, the Company must also pay Parent such termination fee if the Merger Agreement is terminated and, within 12 months following such termination, the Company recommends or enters into certain alternative acquisition arrangements and such acquisition is subsequently consummated.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and which is incorporated herein by reference. The Merger Agreement has been filed to provide information to investors regarding its terms. It is not intended to provide any other factual information about the Company, Parent or Purchaser, their respective businesses, or the actual conduct of their respective businesses during the period prior to the consummation of the Offer, the Merger or the other transactions contemplated by the Merger Agreement. The Merger Agreement and this summary should not be relied upon as disclosure about the Company or Parent. None of the Company’s stockholders or any other third parties should rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or conditions of the Company, Parent, Purchaser or any of their respective subsidiaries or affiliates. The Merger Agreement contains representations and warranties that are the product of negotiations among the parties thereto and that the parties made to, and solely for the benefit of, each other as of specified dates. The assertions embodied in those representations and warranties are subject to qualifications and limitations agreed to by the respective parties and are also qualified in important part by confidential disclosure schedules delivered in connection with the Merger Agreement. The representations and warranties may have been made for the purpose of allocating contractual risk between the parties to the agreements instead of establishing these matters as facts and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors.

Item 8.01

Other Events.

On March 4, 2021, the Company and Parent issued a joint press release announcing the Merger Agreement, a copy of which is filed as Exhibit 99.1 and incorporated herein by reference.

Forward Looking Statements

This filing contains forward-looking statements. These forward-looking statements generally include statements that are predictive in nature and depend on or refer to future events or conditions, and include words such as “expect,” “anticipate,” “outlook,” “could,” “target,” “project,” “intend,” “plan,” “believe,” “seek,” “estimate,” “should,” “may,” “assume” and “continue” as well as variations of such words and similar expressions. By their nature, forward-looking statements involve risks and uncertainty because they relate to events and depend on circumstances that will occur in the future, and there are many factors that could cause actual results and developments to differ materially from those expressed or implied by these forward-looking statements. Forward-looking statements include, among other things, statements about the potential benefits of the proposed transaction; the prospective performance and outlook of the Company’s business, performance and opportunities; any potential strategic benefits, synergies or opportunities expected as a result of the proposed transaction; the ability of the parties to complete the proposed transaction and the expected timing of completion of the proposed transaction; potential marketing or regulatory approvals for bemarituzumab, or potential future revenues from such product; as well as any assumptions underlying any of the foregoing.

These statements are not guarantees of future performance and they involve certain risks, uncertainties and assumptions that are difficult to predict. We caution you that actual outcomes and results may differ materially from what is expressed, implied or forecasted by our forward-looking statements. There can be no guarantee that the proposed tender offer or the transaction described in this press release will be completed, or that it will be completed as currently proposed, or at any particular time. Neither can there be any guarantee that Amgen or the Company’s product, bemarituzumab, will achieve any particular future financial results, or that Amgen will be able to realize any of potential strategic benefits, synergies or opportunities as a result of the proposed acquisition. Nor can there be any guarantee that bemarituzumab will be submitted or approved for sale in any market, or at any particular time.

Neither can there be any guarantee that such product will be successfully commercialized even if regulatory approvals are obtained. In particular, our expectations could be affected by, among other things: uncertainties as to the timing of the tender offer and the merger; the risk that the proposed transaction may not be completed in a timely manner or at all; uncertainties as to the percentage of the Company’s stockholders tendering their shares in the tender offer; the possibility that competing offers or acquisition proposals for the Company will be made; the possibility that any or all of the various conditions to the consummation of the tender offer or the merger may not be satisfied or waived, including the failure to receive any required regulatory approvals from any applicable governmental entities (or any conditions, limitations or restrictions placed on such approvals); regulatory actions or delays or government regulation generally, including potential regulatory actions or delays relating to the completion of the potential transaction described in this release, as well as potential regulatory actions or delays with respect to the development of bemarituzumab; the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement; the effect of this announcement or pendency of the proposed transaction on the Company’s ability to retain and hire key personnel, its ability to maintain relationships with its customers, suppliers and others with whom it does business, its business generally or its stock price; risks related to diverting management’s attention from the Company’s ongoing business operations; the risk that stockholder litigation in connection with the proposed transaction may result in significant costs of defense, indemnification and liability; the potential that the strategic benefits, synergies or opportunities expected from the proposed acquisition may not be realized or may take longer to realize than expected; the successful integration of the Company into Amgen subsequent to the closing of the transaction and the timing of such integration; and other risks and factors referred to from time to time in Amgen’s and Franklin’s filings with the SEC, including Amgen’s current Form 10-K and Franklin’s current Form 10-K on file with the SEC, including those related to the uncertainties inherent in the research and development of new healthcare products, including clinical trial results and additional analysis of existing clinical data; our ability to obtain or maintain proprietary intellectual property protection; safety, quality or manufacturing issues; changes in expected or existing competition; and global trends toward health care cost containment, including government, payor and general public pricing and reimbursement pressures. The effects of the COVID-19 pandemic may give rise to risks that are currently unknown or amplify the risks associated with many of these factors. The Company is providing the information in this filing as of this date and does not undertake any obligation to update any forward-looking statements as a result of new information, future events or otherwise.
