PRMB Investor Alert: Hagens Berman Scrutinizing Alleged Undisclosed Technology Failures and Supply Chain Risks in Pending Primo Brands (PRMB) Lawsuit

Partner Reed Kathrein Urges Investors to Contact Firm Before January 12, 2026 Lead Plaintiff Deadline

SAN FRANCISCO–(BUSINESS WIRE)–National shareholder rights law firm Hagens Berman is alerting investors in Primo Brands Corporation (NYSE: PRMB) that the deadline to move the Court for appointment as lead plaintiff in the pending securities class action lawsuit is January 12, 2026. The firm urges investors who suffered substantial losses to contact our firm now.

The lawsuit seeks to recover investor losses sustained after the disclosure of an allegedly concealed severe, operational crisis following the merger of Primo Water and BlueTriton Brands. The complaint alleges that while management repeatedly assured investors that the integration was “flawless” and would accelerate growth, the alleged reality was a catastrophic failure of technology, logistics, and customer service.

The truth allegedly emerged over multiple disclosures, culminating on November 6, 2025, when Primo Brands announced a dramatic reduction in its full-year adjusted EBITDA guidance and the immediate replacement of its CEO. On this news, the stock crashed 21%, erasing substantial shareholder value.

“The crux of the complaint is the alleged contradiction between the company’s repeated assurances of a ‘flawless’ merger and the new CEO’s admission of ‘self-inflicted’ disruptions that crippled the ReadyRefresh delivery business,” said Reed Kathrein, the Hagens Berman partner leading the firm’s investigation. “We are scrutinizing when management became aware that the foundational technology and operational integration had failed.”

Alleged Undisclosed Merger Failures

The litigation focuses on how the company’s alleged misrepresentations regarding the merger integration masked severe, undisclosed operational risks.

• Misrepresentation Regarding the Integration of BlueTriton Brands: The complaint alleges Primo executives repeatedly assured investors that the merger integration was proceeding “flawlessly,” would accelerate growth, and deliver substantial synergies.

• Concealed Operational Reality: The complaint alleges the company failed to disclose that the accelerated integration process was causing severe technology breakdowns, supply disruptions, and massive customer service issues within its direct delivery segment.

• The First Disclosure Event (August 7, 2025): The company reported weak Q2 results and reduced guidance, partially blaming “service issues,” causing the stock to drop 9%.

• The Final Disclosure Event (November 6, 2025): The market’s misperception of Primo Brands was allegedly fully corrected when the company slashed its EBITDA guidance again and replaced its CEO. The new CEO described the issues as “self-inflicted,” allegedly confirming the severity of the undisclosed operational issues. This final disclosure caused the stock to drop 21%.
