Class A Common Stock, $0.0001 par value per share Grove Collaborative Holdings, Inc. 1301 Sansome Street San Francisco CA 94111 This Amendment No. 1 (this "Amendment") to Schedule 13D is filed by HCI Grove, LLC ("HCI Grove"), HCI Grove Management, LLC ("HCI Grove Management"), Jason H. Karp ("Karp") and Ross Berman ("Berman" and, together with HCI Grove, HCI Grove Management and Karp, the "Reporting Persons"), with respect to the securities of Grove Collaborative Holdings, Inc. (as amended by this Amendment No. 1, the "Schedule 13D"). As previously disclosed, on July 8, 2025, the Reporting Persons delivered the July 8 Letter, which urged the Board to pursue strategic alternatives. In response to discussions between the Reporting Persons and members of the Board and the Company's senior management that followed the July 8 Letter, as of August 7, 2025, the Reporting Persons and the Issuer determined to establish a working group (the "Working Group") comprised of three members of the Issuer's Board (Stuart Landesberg, Larry Cheng and Jeff Yurcisin) and Messrs. Karp and Berman to facilitate the Company's identification and pursuit of avenues to create stockholder value through strategic and operational initiatives. The Working Group is expected to meet periodically to develop recommendations to the Board regarding opportunities to drive value creation for stockholders. Consistent with the July 8 Letter, the Reporting Persons continue to believe that pursuing strategic alternatives, including a sale to a strategic company, a merger with a profitable partner or a take-private transaction with a financial sponsor are the avenues that are most likely to maximize value for the Issuer's stockholders. The Reporting Persons anticipate that, from time to time, they and their representatives will communicate with members of the Board and members of the Issuer's management, in connection with Messrs. Karp and Berman's participation in the Working Group or otherwise, and potentially with other stockholders of the Issuer, with respect to potential strategic opportunities that may be available to the Issuer, potential investment and acquisition opportunities, capital allocation and other operational, strategic, financial or governance matters. Among other things, the Reporting Persons may introduce the Issuer to potential candidates for a business combination or financing transaction, and/or discuss and assist the Working Group in its review of one or more strategic or other opportunities (whether or not the opportunities are introduced by the Reporting Persons). As of the date hereof, the Reporting Persons beneficially own an aggregate of 2,188,109 shares of Class A Common Stock, representing approximately 5.3% of the outstanding shares of Class A Common Stock (based upon 41,012,879 shares of Class A Common Stock issued and outstanding as of August 4, 2025, as set forth on the front cover of the Issuer's Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025 filed with the U.S. Securities and Exchange Commission on August 7, 2025).
