Item 3.03. Material Modification to Rights of Security Holders.
To the extent required by Item 3.03 of Form 8-K, the information set forth in Item 5.03 of this Current Report on Form 8-K is incorporated by reference into this Item 3.03.
Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.
On November 2, 2026, Jasper Therapeutics, Inc. (the “Company”) filed a Certificate of Third Amendment to its Second Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Amendment”), with the Secretary of State of the State of Delaware to effect a 1-for-30 reverse stock split (the “Reverse Stock Split”) of the shares of the Company’s voting common stock, par value $0.0001 per share (“Common Stock”).
As previously disclosed, at the Company’s special meeting of stockholders held on September 30, 2026, the stockholders of the Company approved the Certificate of Amendment to effect, in the sole discretion of the Board of Directors of the Company (the “Board”) at any time on or before December 31, 2026, the Reverse Stock Split at a ratio to be determined by the Board within a range of 1-for-15 to 1-for-35 (or any whole number in between), without reducing the authorized number of shares of Common Stock, as described in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on September 4, 2026. The Board set the Reverse Stock Split ratio at 1-for-30 and approved and authorized the filing of the Certificate of Amendment on October 23, 2026.
As a result of the Reverse Stock Split, every thirty (30) shares of pre-Reverse Stock Split Common Stock will be combined into one (1) share of the Company’s post-Reverse Stock Split Common Stock, without any change in par value per share. Proportionate voting rights and other rights of holders of Common Stock will not be affected by the Reverse Stock Split (other than as a result of the payment of cash in lieu of fractional shares as described below).
Following the Reverse Stock Split, the number of shares of Common Stock issued and outstanding will be reduced from approximately 33.3 million shares as of October 26, 2026 to approximately 1.1 million shares, subject to adjustment for the treatment of fractional shares. The number of authorized shares of Common Stock will remain at 490,000,000 shares and will not be reduced; accordingly, the number of authorized but unissued shares of Common Stock available for future issuance will increase relative to the number of shares outstanding.
No fractional shares of Common Stock will be issued as a result of the Reverse Stock Split. In lieu of any fractional shares to which a holder of Common Stock would otherwise be entitled as a result of the Reverse Stock Split, the Company will pay cash equal to such fraction multiplied by the closing sales price of the Common Stock as reported on the Nasdaq Capital Market on November 5, 2026, which is the trading day immediately preceding the effective date of the Reverse Stock Split.
The Reverse Stock Split will become effective at 12:01 a.m., Eastern Time, on November 6, 2026, and the Common Stock is expected to begin trading on a Reverse Stock Split-adjusted basis on the Nasdaq Capital Market at the opening of the market on November 6, 2026. The trading symbol for the Common Stock will remain “JSPR,” and the new CUSIP number of the Common Stock following the Reverse Stock Split is 471871301.
The Reverse Stock Split will affect all holders of the Common Stock uniformly and will not affect any stockholder’s percentage ownership interest in the Company, except for de minimis changes resulting from the treatment of fractional shares. Stockholders holding their shares in book-entry form or through a bank, broker or other nominee do not need to take any action in connection with the Reverse Stock Split. Their accounts will be automatically adjusted to reflect the number of shares owned. Stockholders of record will be receiving information from Continental Stock Transfer & Trust Company regarding their stock ownership following the Reverse Stock Split and cash in lieu of fractional share payments, if applicable.
1
In addition, the Reverse Stock Split will apply to the Common Stock issuable upon the exercise of the Company’s outstanding warrants and stock options, with proportionate adjustments to be made to the exercise prices thereof. The Company’s outstanding warrants will be adjusted in accordance with their respective terms. Furthermore, the number of shares of Common Stock available for issuance under the Company’s equity incentive plans will be proportionately adjusted for the Reverse Stock Split ratio, such that fewer shares will be subject to such plans.
The summary of the Certificate of Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Amendment, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.
Item 7.01. Regulation FD Disclosure.

Exhibit 99.1

Jasper Therapeutics Announces 1-for-30 Reverse Stock Split
REDWOOD CITY, Calif., November 4, 2026 (GLOBE NEWSWIRE) – Jasper Therapeutics, Inc. (Nasdaq: JSPR) (“Jasper” or the “Company”), a clinical stage biotechnology company focused on the design and development of innovative therapies to treat immune-mediated diseases, today announced a 1-for-30 reverse stock split (“Reverse Split”) of the Company’s common stock (“Common Stock”) that will become effective at 12:01 a.m. Eastern Time on Friday, November 6, 2026. The Company’s Common Stock will begin trading on a split-adjusted basis on the Nasdaq Capital Market commencing at the market open on November 6, 2026. Following the reverse stock split, the Common Stock will continue to trade on the Nasdaq Capital Market under the symbol “JSPR” with a new CUSIP number of 471871301.
As a result of the Reverse Split, every thirty (30) shares of the Company’s issued and outstanding Common Stock will be automatically combined and converted into one (1) issued and outstanding share of Common Stock without any change in the par value of $0.0001 per share. No fractional shares will be issued as a result of the Reverse Split, and stockholders who otherwise would be entitled to a fractional share will automatically be entitled to receive cash in lieu of such fractional shares equal to such fraction multiplied by the closing sales price of the Common Stock as reported on the Nasdaq Capital Market on November 5, 2026. Each stockholder’s pro-rata percentage ownership will remain unchanged as a result of the Reverse Split, except for minor changes resulting from the treatment of fractional shares. The Reverse Split will not change the authorized number of shares of Common Stock and, immediately after the Reverse Split becomes effective, there will be approximately 1.11 million shares of Common Stock issued and outstanding (compared to approximately 33.3 million shares immediately prior to the Reverse Split), subject to adjustment for fractional shares.
The Reverse Split will apply to the shares of Common Stock issuable upon the exercise of Jasper’s current outstanding warrants and stock options, with proportionate adjustments to be made to the exercise prices thereof. The Company’s outstanding warrants will be adjusted in accordance with their respective terms. Furthermore, the number of shares of Common Stock available for issuance under Jasper’s equity incentive plans will be proportionately adjusted for the reverse stock split ratio, such that fewer shares will be subject to such plans.
At Jasper’s special meeting of stockholders held on September 30, 2026, Jasper’s stockholders approved the Reverse Split and granted Jasper’s board of directors discretionary authority to select a ratio for the Reverse Split ranging from 1-for-15 to 1-for-35. Jasper’s board of directors approved the Reverse Split at a ratio of 1-for-30 on October 23, 2026.
Jasper’s transfer agent, Continental Stock Transfer & Trust Company, will provide information to stockholders regarding their stock ownership following the Reverse Split and cash in lieu of fractional share payments, if applicable. Stockholders holding their shares in book-entry form or through a bank, broker or other nominee do not need to take any action in connection with the Reverse Split. Their accounts will be automatically adjusted to reflect the number of shares owned. Beneficial holders are encouraged to contact their bank, broker or other nominee with any procedural questions.
