Item 1 Comment:
This Amendment No. 2 ("Amendment No. 2") amends the Schedule 13D originally filed on October 30, 2024, as amended by Amendment No. 1 thereto on February 7, 2025 (the "Statement"), and is filed jointly by Brian G. Atwood, Lynne H. 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").. Capitalized terms used herein but not defined shall have the meaning attributed to them in the Schedule 13D. | ||

Item 3 is hereby supplemented as follows:
On March 28, 2025, Mr. Atwood exercised 294,460 Pre-Funded Warrants and directed the issuance of the shares of Common Stock issuable upon exercise thereof to be delivered to the Trust. As a result of a processing error, the shares of Common Stock were set forth on an account statement as of March 31, 2025 that was not delivered to Mr. Atwood until April 4, 2025. Each of the Pre-Funded Warrants and Warrants contains a beneficial ownership limitation, preventing the exercise thereof if and to the extent that the exercise thereof would result in the holder thereof, together with its affiliates who may be deemed to have beneficial ownership of the securities held thereby, being deemed to have beneficial ownership of greater than 9.99% of the outstanding shares of Common Stock. As a result, such Pre-Funded Warrants and Warrants are not presently exercisable in excess of such limitation and none of the Reporting Persons may be deemed to have beneficial ownership of such shares of Common Stock issuable upon exercise thereof. | ||
| Item 4. | Purpose of Transaction | |
Item 4 is hereby supplemented as follows:
The information set forth in Item 3 of this Statement, as amended therein, is incorporated herein by reference. | ||

| (b) | See Items 7-11 of the cover pages of this Statement, as amended, and Item 2 of the Statement. | |
| (c) | On March 4, 2025, the Issuer granted stock option awards to each of its non-management directors, including Mr. Atwood. Mr. Atwood received options to purchase an aggregate of 29,871 shares of Common Stock at an exercise price of $1.43, of which 50%, or 14,936 are subject to time-based vesting, with the remainder subject to performance-based vesting conditions. Except for such option awards and the other transactions reported in this Statement, none of the Reporting Persons has effected any transactions in the Issuer's securities within the past 60 days. | |
| (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. | |
| Item 6. | Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer | |
Item 6 is hereby supplemented as follows:
The information set forth in Items 3 and 4 of this Statement is incorporated herein by reference. | ||
