Attached are communications to employees of Moderna, Inc., a Delaware corporation (the “Company”), first made available on October 21, 2025 (the “Employee Communications”), related to the proposed stock option exchange program that would allow certain employees who are not executive officers to exchange significantly out-of-the-money or “underwater” stock options, meaning outstanding stock options that have an exercise price that is significantly greater than the market price for the Company’s common stock, for the issuance of new stock options that will be exercisable for fewer shares of the Company’s common stock, with an exercise price equal to the fair market value of the Company’s common stock on the grant date of the new stock options and with new vesting terms (the “Option Exchange Program”). The Option Exchange Program is subject to Moderna shareholder approval at a Special Meeting of Shareholders to be held on November 12, 2025, and is further described in the definitive proxy statement (the “Proxy Statement”) that was filed with the Securities and Exchange Commission (“SEC”) on October 15, 2025.
Neither the Proxy Statement nor Employee Communications constitute an offer to holders of the Company’s outstanding stock options to exchange those options. The Option Exchange Program will only be implemented, if at all, if the Company’s shareholders first approve the Option Exchange Program.
The Option Exchange Program has not yet commenced. Even if shareholder approval is obtained, the Company may decide not to implement the Option Exchange Program. The Company will file a Tender Offer Statement on Schedule TO with the SEC if and when the Option Exchange Program commences. Option holders should read the Tender Offer Statement on Schedule TO and other related materials when those materials become available, because they will contain important information about the Option Exchange Program.
The Company’s shareholders and option holders will be able to obtain the written materials described above and the other documents filed by the Company with the SEC free of charge from the SEC’s website at www.sec.gov or by directing a written request to: Corporate Secretary, at 325 Binney Street, Cambridge, Massachusetts 02142.
