Edminster and the Atwood-Edminster Trust dtd 4-2-2000 (the "Trust" and, together with Mr. Atwood and Ms. Edminster, the "Reporting Persons"), with respect to the Common Stock, par value $0.0001 per share ("Common Stock"), of CERo Therapeutics Holdings, Inc., a Delaware corporation (the "Issuer")..

    Item 3.Source and Amount of Funds or Other Consideration
     
    Item 3 is hereby supplemented as follows: On February 7, 2025, pursuant to a Securities Purchase Agreement, dated February 5, 2025, Mr. Atwood purchased 306,120 Pre-Funded Warrants, which are exercisable at any time on or after the date of issuance for an exercise price of $0.0001 per share, for shares of Common Stock, and 306,120 Warrants, which will become exercisable immediately upon the Issuer's receipt of stockholder approval (the "Stockholder Approval Date") for an exercise price of $1.96 per share, for shares of Common Stock. The aggregate purchase price for each pair of Pre-Funded Warrants and Warrants was $1.9599. The Warrants will expire on the fifth anniversary of the Stockholder Approval Date. In addition, GVN, LLC, a limited liability company of which the sole member is the Trust, and of which Brian G. Atwood and Lynne H.

The purchase of the Pre-Funded Warrants and Warrants was financing through the use of personal funds of the Reporting Persons.

As a result, such Pre-Funded Warrants and Warrants are not presently exercisable and none of the Reporting Persons may be deemed to have beneficial ownership of the shares of Common Stock issuable upon exercise thereof.

    (d)
    No other person is known to the Reporting Persons to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock covered by this Statement.
    (e)
    Not applicable.
