Legion Partners Holdings, LLC, a Delaware limited liability company (“Legion Partners Holdings”), and the other participants in this solicitation (collectively, “Legion” or “we”) are significant shareowners of Primo Water Corporation, a corporation continued under the laws of the Province of Ontario (“Primo”, “PRMW” or the “Company”), who beneficially own, in the aggregate, 2,393,465 common shares, no par value per share (the “Common Stock”), of the Company, constituting approximately 1.5% of the outstanding shares of Common Stock.

We are sending this proxy statement supplement (the “Proxy Supplement”) in connection with the solicitation of proxies relating to the upcoming 2023 annual and special meeting of shareowners including any and all adjournments, postponements, continuations or reschedulings thereof, or any other meeting of shareowners held in lieu thereof) (the “Annual Meeting”). The Annual Meeting will be held in virtual format on Wednesday, May 3, 2023, at 8:00 a.m. (local time in Tampa), via a live audio webcast at www.virtualshareholdermeeting.com/PRMW2023, where you will be able to vote electronically and submit questions while the meeting is being held. Legion Partners Holdings filed its definitive proxy statement for the Annual Meeting with the Securities and Exchange Commission (the “SEC”) on April 3, 2023 (the “Definitive Proxy Statement”). Defined terms used but not defined herein have the meanings ascribed to them in the Definitive Proxy Statement.

On page 39 of the Definitive Proxy Statement under the “VOTES REQUIRED FOR APPROVAL” section, the first paragraph is hereby amended and restated to read as follows:

Proposal 1: Election of Directors ─ According to the Company’s proxy statement, so long as the Nomination Notice is deemed valid by a court of competent jurisdiction through a final, non-appealable ruling, the election of directors to the Board at the Annual Meeting will remain contested and the ten (10) director nominees receiving the highest number of “FOR” votes will be elected as directors. Shareowners are permitted to vote for less than ten (10) or any combination (up to ten (10) total) of the Legion Nominees and the Company’s nominees on the WHITE universal proxy card. If you vote “FOR” less than ten (10) nominees in Proposal 1, when duly executed, your proxy card will be voted “FOR” the nominees you have so marked and default to a “WITHHOLD” vote with respect to any nominee left unmarked. If you vote “FOR” more than ten (10) nominees, all of your votes on Proposal 1 will be invalid and will not be counted. Abstentions, withhold votes and any broker non-votes will have no direct effect on the outcome of the election of directors.

Legion Partners Holdings strongly recommends that shareowners vote “for” the Legion Nominees – Timothy P. Hasara and Derek R. Lewis, and not to vote “for” the four Company nominees who we believe are most responsible for Primo’s underperformance - Jerry Fowden, Gregory Monahan, Billy D. Prim and Eric Rosenfeld.
