Important Information and Where to Find It
This Current Report on Form 8-K is being made in respect of certain stockholder proposals arising out of the Exchange Offer and related transaction support agreement. The stockholder proposals will be submitted to the Company’s stockholders for their consideration and approval at a special meeting of the Company’s stockholders to be held on July 14, 2026. In connection with the stockholder proposals, the Company has filed with the Securities and Exchange Commission (“SEC”) a definitive proxy statement on Schedule 14A (the “Proxy Statement”) on June 9, 2026, which contains important information about the stockholder proposals and related matters. The Company may also file other relevant documents with the SEC regarding the stockholder proposals. This Current Report on Form 8-K is not a substitute for the Proxy Statement or any other document that the Company may file with the SEC. BEFORE MAKING ANY VOTING DECISION WITH RESPECT TO THE STOCKHOLDER PROPOSALS, INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE PROXY STATEMENT AND ANY OTHER RELEVANT DOCUMENTS THAT ARE FILED OR WILL BE FILED WITH THE SEC, AS WELL AS ANY AMENDMENTS OR SUPPLEMENTS TO THESE DOCUMENTS, CAREFULLY AND IN THEIR ENTIRETY IF AND WHEN THEY BECOME AVAILABLE BECAUSE THEY CONTAIN OR WILL CONTAIN IMPORTANT INFORMATION ABOUT THE STOCKHOLDER PROPOSALS, THE RISKS RELATED THERETO AND RELATED MATTERS.
Investors and security holders may obtain free copies of the Proxy Statement and other documents containing important information about the Company and the Stockholder Proposals that are filed or will be filed with the SEC by the Company at the SEC’s website at www.sec.gov or at the Company’s website at ir.gossamerbio.com.
Participants in the Solicitation
The Company and certain of its directors, executive officers and other members of management and employees may, under the rules of the SEC, be deemed to be participants in the solicitation of proxies from the Company’s stockholders in connection with the Stockholder Proposals. Information regarding the Company’s directors and named executive officers, including a description of their direct or indirect interests, by security holdings or otherwise, is contained in the definitive proxy statement for the 2026 annual meeting of stockholders, which was filed with the SEC on April 24, 2026 (the “2026 Annual Meeting Proxy Statement”). To the extent holdings of the Company’s securities by such directors or executive officers (or the identity of such directors or executive officers) have changed since the information set forth in the 2026 Annual Meeting Proxy Statement, such information has been or will be reflected on the Initial Statements of Beneficial Ownership on Form 3 or Statements of Changes in Beneficial Ownership on Form 4 filed with the SEC. Additional information regarding the interests of the Company’s directors and executive officers in the Stockholder Proposals is included in the Proxy Statement filed with the SEC. You may obtain free copies of these documents using the sources indicated above.
