TriMas (NASDAQ: TRS) surged 10.74% in premarket trading after announcing a definitive agreement to sell its Aerospace segment for $1.45 billion in an all-cash transaction to an affiliate of Tinicum L.P., with Blackstone funds as minority investors. The deal, valued at 18x LTM adjusted EBITDA, aligns with the company’s strategic shift to focus on its high-margin packaging platform.

The premium valuation and clarity on post-divestiture strategy drove the sharp premarket rally.
