Increased Authorization After Repurchasing Over Three Million Shares in Fourth Quarter 2025

TriMas (NASDAQ:TRS) today announced that its Board of Directors has increased the Company's common stock share repurchase authorization to a total of up to $150 million, adding to the $48.9 million remaining under the previous authorization.

During 2025, TriMas repurchased 3,124,866 shares of its outstanding common stock for $103.3 million, with more than three million shares repurchased since the announcement of the Aerospace divestiture. As of December 31, 2025, the Company had approximately 37.6 million shares outstanding.

"Increasing our share repurchase authorization to $150 million reflects our confidence in TriMas' long‑term value," said Thomas Snyder, TriMas President and Chief Executive Officer. "As we continue to focus our portfolio and deploy capital with discipline, this expanded authorization provides additional flexibility to repurchase shares as we advance our strategic priorities and complete the pending divestiture."

The extent to which TriMas repurchases its shares, and the timing of such repurchases, will depend upon a variety of factors, including market conditions, share price, regulatory requirements, other available uses of capital and other corporate considerations. The share repurchase program does not require the purchase of any minimum number of shares and may be suspended, modified or discontinued at any time without prior notice.
