Explanation of Responses:

1. Effective as of July 27, 2026 (the "Effective Time"), a wholly owned subsidiary of VYNE Therapeutics Inc. ("VYNE") merged with and into Yarrow Bioscience, Inc. ("Yarrow") with Yarrow continuing as a wholly owned subsidiary of VYNE and the surviving corporation of the merger (the "Merger") under the name "Yarrow Bioscience Operating Company Corp." In connection with the completion of the Merger, VYNE changed its name to "Yarrow Bioscience, Inc." (hereinafter, the "Issuer").

2. Represents options to purchase shares of common stock, par value $0.0001, of the Issuer ("Issuer Common Stock") received by the Reporting Person in the Merger in exchange for options to purchase shares of common stock of Yarrow held by the Reporting Person prior to the Merger. At the Effective Time, the Issuer assumed each such Yarrow option, whether vested or unvested, and converted it into an option to purchase shares of Issuer Common Stock on the same terms and conditions as were in effect immediately prior to the Effective Time.

3. This option represents a right to purchase 87,820 shares of Issuer Common Stock, one quarter of which will vest on April 17, 2027, with the remaining three quarters vesting in equal monthly installments over the following three years, subject to the Reporting Person's continued service to the Issuer on each such vesting date.
