Item 1 Comment:
This Amendment No. 1 to Schedule 13D is being filed by AI Biotechnology LLC, Access Industries Holdings LLC ("AIH"), Access Industries Management, LLC ("AIM") and Len Blavatnik (collectively, the "Reporting Persons", and each, a "Reporting Person") in respect of the common stock, par value $0.0001 per share (the "Common Stock"), of Yarrow Bioscience, Inc. (the "Issuer"). The Schedule 13D filed with the Securities and Exchange Commission ("SEC") on November 13, 2023 (the "Schedule") is hereby amended and supplemented by the Reporting Persons as set forth below in this Amendment No. 1. This Amendment is filed by the Reporting Persons in accordance with Rule 13d-2 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and refers only to information that has materially changed since the filing of the Schedule. The items identified below, or the particular paragraphs of such items which are identified below, are amended as set forth below. Unless otherwise indicated, all capitalized terms used and not defined herein have the respective meanings assigned to them in the Schedule. The Schedule was originally filed with respect to VYNE Therapeutics Inc., which changed its name to Yarrow Bioscience, Inc. upon the consummation of the Merger described in Item 4 below. | ||
| Item 4. | Purpose of Transaction | |
The disclosure in Item 4 is hereby amended and supplemented by adding the following at the end thereof: On July 27, 2026, pursuant to the A
greement and Plan of Merger and Reorganization, dated as of December 17, 2025, as amended by Amendment No. 1 thereto on January 30, 2026, by and among VYNE Therapeutics Inc., Yellow Merger Sub Corp., a Delaware corporation and wholly owned subsidiary of VYNE Therapeutics Inc., and Yarrow Bioscience, Inc., a Delaware corporation ("Pre-Merger Yarrow"), Yellow Merger Sub Corp. merged with and into Pre-Merger Yarrow, with Pre-Merger Yarrow continuing as a wholly owned subsidiary of VYNE Therapeutics Inc. and the surviving corporation of the merger (the "Merger"). In connection with the completion of the Merger, VYNE Therapeutics Inc. changed its name to Yarrow Bioscience, Inc. Prior to the consummation of the Merger, the Issuer effected a 1-for-50 reverse stock split of its Common Stock by filing a Certificate of Amendment to its Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, which became legally effective on July 24, 2026 (the "Reverse Stock Split"). Upon the effectiveness of the Reverse Stock Split, every 50 shares of Common Stock issued and outstanding immediately prior thereto were automatically and without further action on the part of the Issuer or any holders of Common Stock combined into one share of Common Stock. No fractional shares were issued as a result of the Reverse Stock Split. Instead, any stockholder who would otherwise have been entitled to a fractional share, after aggregating all fractions of a share to which such stockholder would otherwise have been entitled, became entitled to receive a cash payment equal to the product of the resulting fractional interest in one share of Common Stock multiplied by the closing price per share as reported by Nasdaq on July 23, 2026. As a result of the Reverse Stock Split, the 1,116,585 shares of Common Stock held by AI Biotechnology were combined into 22,331 whole shares of Common Stock, and AI Biotechnology became entitled to receive cash in lieu of the resulting 0.70 fractional share. In addition, pursuant to the terms of the Warrants, the exercise price of the Warrants and the number of shares of Common Stock issuable upon exercise thereof were proportionately adjusted, with the number of shares of Common Stock issuable upon exercise of the Warrants being adjusted from 7,792,448 shares to 155,849 shares. | ||
| Item 5. | Interest in Securities of the Issuer | |
| (a) | Item 5 of the Schedule 13D is hereby amended and restated as follows: The responses of each of the Reporting Persons with respect to Rows 11, 12 and 13 of the cover pages of this Schedule 13D (including, but not limited to, the footnotes thereto) are incorporated herein by reference. The responses of each of the Reporting Persons with respect to Rows 7, 8, 9 and 10 of the cover pages of this Schedule 13D that relate to the number of shares of Common Stock as to which each of the persons or entities referenced in Item 2 above has sole or shared power to vote or to direct the vote of and sole or shared power to dispose of or to direct the disposition of (including, but not limited to, the footnotes thereto) are incorporated herein by reference. | |
| (b) | 22,331 shares of Common Stock and Warrants to purchase 155,849 shares of Common Stock are owned directly by AI Biotechnology and may be deemed to be beneficially owned by AIM, AIH and Mr. Blavatnik because (i) Mr. Blavatnik controls AIM and AIH, (ii) AIM controls AIH, and (iii) AIH owns all of the voting units of AI Biotechnology. Each of AIH, AIM and Mr. Blavatnik, and each of their affiliated entities and the officers, partners, members and managers thereof, disclaims beneficial ownership of these securities. | |
| (c) | The information set forth in Item 4 of this Schedule 13D is incorporated by reference herein. Other than as disclosed herein, the Reporting Persons have not effected any transactions in the Common Stock during the past 60 days. | |
| (d) | Not applicable. | |
