On May 15, 2026, the Board of Directors (the “Board”) of Primo Brands Corporation (the “Company”) increased the size of the Board from 10 to 11 directors, effective May 15, 2026.

Additionally, on May 15, 2026, the Board appointed Andrea Brimmer to serve on the Board, effective May 15, 2026, to fill the newly created vacancy resulting from the increase in the size of the Board. Ms. Brimmer will serve as a director until the Company’s 2027 Annual Meeting of Stockholders or until her successor shall have been elected and qualified, subject to her earlier death, resignation, retirement, disqualification or removal. Ms. Brimmer will also serve as a member of the Board’s Sustainability Committee.

Ms. Brimmer, age 60, has served as Chief Marketing and Public Relations Officer of Ally Financial Inc., a leading digital financial services company, since 2015. Ms. Brimmer has served as a director of eHealth, Inc. since December 2018. She also serves on the boards of the Women’s Sports Foundation, the Ad Council and the Detroit Sports Commission. Ms. Brimmer holds a Bachelor of Science degree in advertising from Michigan State University. The Board believes Ms. Brimmer’s extensive experience in marketing, public relations and business development and her executive leadership experience qualify her to serve as a director.

Since the beginning of the Company’s last fiscal year, there have been no transactions, and there are no currently proposed transactions, to which the Company was or is a participant and in which Ms. Brimmer had or is to have a direct or indirect material interest that would require disclosure pursuant to Item 404(a) of Regulation S-K.

Ms. Brimmer will receive compensation for her service as a director consistent with the Company’s Non-Employee Director Compensation Program as disclosed in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on March 18, 2026. In accordance with the Company’s customary practice, the Company is entering into its standard form of indemnification agreement with Ms. Brimmer, which is attached as Exhibit 10.26 to the Company’s Current Report on Form 8-K 12G3/A dated November 12, 2024.
