On March 17, 2026, Serina Therapeutics, Inc. (the “ Company ”) entered into a Securities Purchase Agreement (the “ Purchase Agreement ”) with Greg Bailey, as lead investor, and certain other investors (collectively, the “ Investors ”), pursuant to which the Company agreed to issue and sell, in a private placement (the “ Private Placement ”), shares of its common stock, par value $0.0001 per share (the “ Common Stock ”), pre-funded warrants to purchase shares of Common Stock (the “ Pre-Funded Warrants ”) redeemable warrants to purchase shares of Common Stock (the “ Redeemable Warrants ” and, together with the Common Stock and the Pre-Funded Warrants, the “ Securities ”). The purchase price for the Securities in the Private Placement is $2.25 per share of Common Stock (or $2.2499 per Pre-Funded Warrant, reflecting a $0.0001 exercise price). Each Investor will also receive a Redeemable Warrant to purchase a number of shares of Common Stock equal to 50% of the shares purchased (including shares underlying Pre-Funded Warrants), at an exercise price of $5.00 per share, a four-year term, and customary beneficial ownership limitations. The Redeemable Warrants are not exercisable until six months after the date of the Purchase Agreement. The exercise price and the number of shares of Common Stock issuable upon exercise of the Pre-Funded Warrants and the Redeemable Warrants is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Common Stock. The Company has the right to call the Redeemable Warrants, in whole or in part, for redemption at a price of $0.01 per underlying share of Common Stock on the earlier of (i) 30 days after the dosing of the first patient in Cohort 2 of the Company’s SER-252 Phase 1b single-ascending dose (SAD) clinical study or (ii) September 30, 2026, provided that the closing price of the Common Stock reported equals or exceeds $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) on the business day prior to the date on which the notice of redemption is sent.  Holders of Redeemable Warrants will have 30 days to exercise the Redeemable Warrants subject to any such call by the Company. The Purchase Agreement provides that at the initial closing on or before March 20, 2026, Investors would purchase at least an aggregate of $15.0 million of Securities, with one or more additional closings for aggregate gross proceeds of at least $5.0 million and up to $15.0 million to be funded within 20 days after the initial closing, with the lead investor obligated to backstop such amount, subject to syndication. Any additional amounts may be funded within a subsequent 20-day period. As of March 20, 2026, Investors funded the full $15.0 million of the first closing. As a condition to the initial closing, the Company and the holders of its outstanding Senior Unsecured Convertible Promissory Note, dated September 9, 2025, entered into an amendment of such note, effective upon the initial closing, removing any further obligations to borrow or loan funds under the Note. Notwithstanding anything in the Purchase Agreement to the contrary, the Company will not issue shares of Common Stock to Dr. Bailey in the Private Placement unless and until the Company first obtains stockholder approval in accordance with the rules of the NYSE American. The Company has agreed to seek such stockholder approval at the next annual meeting of its stockholders following the initial closing and, if such approval is not obtained at such annual meeting, the Company shall call subsequent stockholder meetings approximately every ninety (90) days thereafter until such stockholder approval is obtained. Registration Rights Agreement In connection with each closing, the Company will enter into a registration rights agreement with the Investors providing for the resale registration of the shares of Common Stock issued or issuable in the Private Placement. The registration rights agreement provides that the Company will file a registration statement covering the resale of all of the registrable securities (as defined in the registration rights agreement) with the Securities and Exchange Commission (the "SEC") no later than the 45th calendar day following the date on which at least $20 million of the Securities have been sold, and have the registration statement declared effective by the SEC as promptly as practicable after the filing thereof, but no later than the 90 th date following the filing of the registration statement in the event of a "full review" by the SEC.
