The full text of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information in this Item 2.02 (including Exhibit 99.1) shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the "Securities Act"), or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On November 12, 2025, the Company’s board of directors (the “Board”) approved the following changes to executive leadership effective as of December 1, 2025 (the “Effective Date”).

On November 12, 2025, B. John Lindeman tendered his resignation from his position as Chief Executive Officer and director of the Company to be effective on the Effective Date. Mr. Lindeman’s resignation is not due to any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

On the Effective Date, William Toler will assume the role of Chief Executive Officer. Mr. Toler, age 66, previously served as the Company’s Chief Executive Officer from January 1, 2019, until his appointment to the office of Executive Chairman of the Board in January 2025. Prior to joining Hydrofarm in 2019, Mr. Toler was the Chief Executive Officer of Hostess Brands, Inc. (Nasdaq: TWNK) (“Hostess”), a food and beverage company, from April 2014 to March 2018. Under his leadership, Hostess successfully re-established the iconic Hostess brand as a leader within the sweet baked goods category, returned the company to profitability and transitioned Hostess from a private to public company. Mr. Toler has over 35 years of executive leadership experience in supply chain management and consumer packaged goods, including previously having served as Chief Executive Officer of AdvancePierre Foods, from September 2008 to August 2013, and President of Pinnacle Foods. He has also held executive roles at Campbell Soup Company (NYSE: CPB), Nabisco, and Procter & Gamble (NYSE: PG). Mr. Toler served on the board of directors of Collier Creek Holdings from September 2018 to September 2020, Hostess Brands from May 2014 to March 2018, AdvancePierre Foods from 2008 to 2013 and Pinnacle Foods from 2007 to 2008. In addition, Mr. Toler has also served as a senior advisor at Oaktree Capital Management, an investment management firm, from September 2013 to April 2014. Mr. Toler holds a B.A. in Business Management and Economics from North Carolina State University.

In connection with his appointment as Chief Executive Officer, the Company entered into an employment agreement with Mr. Toler dated November 12, 2025 (the “Employment Agreement”), which sets forth the terms and conditions of Mr. Toler’s employment. Pursuant to the terms of the Employment Agreement, the Company will pay Mr. Toler a base salary of $275,000. Mr. Toler will be eligible to receive an annual performance bonus with a target of 100% of his base salary, based upon an assessment of his performance by the Board. Mr. Toler will also be eligible to participate in the Company’ standard employee benefits and receive reimbursement for reasonable business travel, entertainment or other expenses in accordance with the Company’s reimbursement policy in effect at the time. Mr. Toler is subject to certain restrictive covenants under the Employment Agreement including among other things, non-competition, non-solicitation, and non-disparagement provisions that apply during the term of Mr. Toler’s employment and for sixth months thereafter.

In the event of resignation without Good Reason, termination for Cause or termination by either party of his employment (each as defined in the Employment Agreement), Mr. Toler will receive (i) his base salary accrued through the last date of his employment; (ii) any unused vacation accrued through the last day of his employment; (iii) any unpaid annual bonus for the calendar immediately prior to the date of separation; and (iv) reimbursement for any unreimbursed business expense, subject to certain terms and conditions in the Employment Agreement (“Accured Amounts”). In the event of termination of his employment other than for Cause, his resignation for Good Reason, or termination due to the Company’s non-renewal of the Employment Agreement (each as defined in the Employment Agreement), provided such termination or resignation constitutes a Separation of Service (as defined under Treasury Regulation Section 1. 409A-1(h)), Mr. Toler will receive Accrued Amounts. Subject to the execution of a release of claims in favor of the Company and compliance with the restrictive covenants and other terms of the Employment Agreement, Mr. Toler will also receive (i) cash severance in an amount equal to one year of his base salary in effect as of the date of separation; (ii) reimbursement for the premium charged for Consolidated Budget Reconciliation Act of 1985 (COBRA) coverage until the earlier of the sixth month anniversary of the date of separation or the date he obtains

alternative coverage; and (iii) accelerated vesting over the twelve month period following the separation of all unvested time-based awards of restricted stock units and stock options.

The foregoing description of the Employment Agreement is a summary of its material terms, does not purport to be complete and is qualified in its entirety by reference to the full text of the Employment Agreement, which is filed as Exhibit 10.1 hereto and is incorporated herein by reference. Mr. Toler will no longer receive compensation for services as a director of the Company.

There are no arrangements or understanding between Mr. Toler and any other persons or entities with respect to their appointments, and there are no family relationships between Mr. Toler and any of the Company’s directors, executive officers, or persons nominated or chosen by the Company to become a director or executive officer. Mr. Toler has not been involved in any related person transactions with the Company that would require disclosure under Item 404(a) of Regulation S-K.
