Item 8.01 Other Events.

TriMas Corporation (the “Company”) has attached hereto as Exhibit 99.1 a press release containing a preliminary review of its financial performance for the first quarter of 2011.

At this time, the Company is finalizing its financial results for the first quarter of 2011 and will report those results on April 28, 2011. The results described in the attached press release are estimated, preliminary and may change. Since the Company has not completed the normal quarterly closing and review procedures for the quarter ended March 31, 2011, and subsequent events may occur that require adjustments to these results, there can be no assurance that the final results for the quarter ended March 31, 2011 will not differ materially from these estimates. These estimates should not be viewed as a substitute for full interim financial statements prepared in accordance with GAAP.
