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 under leading brand names for customers primarily in the consumer products and industrial markets.

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries and, in the opinion of management, contain all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of financial position and results of operations. 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, and 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.

Results of operations for interim periods are not necessarily indicative of results for the full year. The accompanying consolidated financial statements and notes thereto should be read in conjunction with the Company's 2025 Annual Report on Form 10-K.

On March 16, 2026, the Company completed the previously announced sale of its Aerospace segment ("Aerospace"), a transaction entered into with an affiliate of Tinicum L.P., and funds managed by Blackstone, Inc. on November 4, 2025. Aerospace was sold for approximately $1,456.9 million in cash, subject to customary post-closing adjustments. The financial results of Aerospace were previously reported within the Company's Aerospace reportable segment, and are presented as discontinued operations for all periods presented in the financial statements attached hereto.
