Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On March 12, 2009, TriMas Corporation (the “Corporation”) received written notice from NYSE Regulation, Inc. that the Corporation had fallen below the continued listing standard of the New York Stock Exchange, Inc. (“NYSE”) set forth in Section 802.01B of the NYSE Listed Corporation Manual because over a 30 trading-day period the Corporation’s total market capitalization was less than $75 million and, at the same time, its stockholders’ equity was less than $75 million. As of March 10, 2009, the Corporation’s 30 trading-day average market capitalization was approximately $43.2 million. The Corporation’s last reported stockholders’ equity was $54.9 million as of December 31, 2008, which reflected the impact of the Corporation recording a non-cash goodwill and indefinite-lived intangible asset impairment charges of $172.2 million in the fourth quarter of 2008.

Under NYSE rules, the Corporation has 45 calendar days from receipt of the notice to submit a plan that demonstrates its ability to achieve compliance with the continued listing standard within 18 months. The Corporation has notified the NYSE of its intent to submit a plan to remedy its non-compliance. Upon receipt of the Corporation’s plan, the NYSE has 45 calendar days to review and determine whether the Corporation has made a reasonable demonstration of its ability to come into conformity with the relevant standard within the 18-month period. The NYSE will either accept the plan at which time the Corporation will be subject to ongoing monitoring for compliance with the plan, or the NYSE will not accept the plan and the Corporation will be subject to suspension and delisting procedures.

As required under NYSE rules, the Corporation issued a press release on March 13, 2009 disclosing that it had received the notice and that the Corporation intends to submit a plan to attain compliance with the NYSE continued listing standards. A copy of the press release is attached to this Form 8-K as an exhibit.

TRIMAS RECEIVES NOTICE REGARDING NYSE LISTING STANDARD

BLOOMFIELD HILLS, Michigan, March 13, 2009 — TriMas Corporation (NYSE: TRS) — a diversified engineered and applied products company — today announced that it has been notified by NYSE Regulation, Inc. that it is not in compliance with one of the continued listing standards of the New York Stock Exchange (NYSE). As previously disclosed, TriMas had expected this notice and is developing a plan to remedy the noncompliance.

TriMas is considered below criteria for the continued listing standards because over a 30 day-trading period its total market capitalization was less than $75 million and its most recently reported stockholders’ equity was less than $75 million. In accordance with the NYSE’s continued listing criteria, TriMas intends to submit a plan to the NYSE within the required 45-day period demonstrating how it plans to comply with the NYSE’s continued listing standards. This plan will build upon the Company’s most recent earnings materials reflecting its continued capacity to improve its balance sheet, while supporting its business initiatives to improve profitability and generate strong cash flow.
