05:59 PM EDT, 10/14/2025 (MT Newswires) -- Sturm, Ruger & Co. ( RGR ) adopted a one-year shareholder rights plan after Beretta Holding disclosed a growing stake in the gunmaker and signaled interest in potential collaborations.

The plan, effective immediately, is designed to protect shareholder value and prevent Beretta or others from gaining control without fair compensation, Ruger said Tuesday in a statement.

Beretta disclosed that it owns 9% of Ruger's shares and "refused to enter into a customary confidentiality and standstill agreement to facilitate discussions," according to the statement.

The rights plan gives the board time to evaluate Beretta's intentions while remaining open to discussions on "lasting value creation," Ruger Chairman John Cosentino Jr. said in the statement.

Beretta didn't immediately reply to a request for comment from MT Newswires.

Ruger shares rose 0.7% in after-hours trading.
