Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

TriMas Corporation ("TriMas" or the "Company"), and its consolidated subsidiaries, designs, engineers and manufactures innovative products for customers primarily in the consumer products and industrial markets.

The preparation of financial statements requires management of the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities. Actual results may differ from such estimates and assumptions due to risks and uncertainties, including uncertainty and volatility in the current economic environment due to input cost inflation, supply chain disruptions, shortages in global markets for commodities, logistics and labor. To the extent there are differences between these estimates and actual results, the Company's consolidated financial statements may be materially affected.

On November 4, 2025, the Company announced it entered into a definitive agreement to sell its Aerospace segment ("Aerospace") to an affiliate of Tinicum L.P., and funds managed by Blackstone, Inc. for a purchase price of approximately $1.45 billion in cash, subject to customary post-closing adjustments. The closing is expected to occur by the end of the first quarter of 2026, subject to customary regulatory approvals and closing conditions. The financial results of Aerospace were previously reported within the Company's Aerospace reportable segment, and are presented as held for sale in the consolidated balance sheet and as discontinued operations in the consolidated statement of income for all periods presented in the financial statements attached hereto.
