FOR IMMEDIATE RELEASE

TRIMAS CORPORATION REPORTS SECOND QUARTER 2008 RESULTS

Company Achieves Record Quarterly Sales

BLOOMFIELD HILLS, Michigan, July 31, 2008 – TriMas Corporation (NYSE: TRS) today announced financial results for the quarter ended June 30, 2008. The Company reported record quarterly revenues from continuing operations of $297.1 million, an increase of 3.3% from the second quarter of 2007. Second quarter 2008 income from continuing operations was $9.4 million, or $0.28 diluted earnings per share, including $0.04 per share in previously announced restructuring costs. In comparison, the second quarter 2007 net loss from continuing operations was $4.1 million, or a loss of $0.15 per diluted share, which included the $0.52 per share impact of costs and expenses related to use of the initial public offering proceeds. The Company reported net cash provided by operating activities, net of acquisition impact, of $13.6 million in the second quarter of 2008, compared to net cash used for operating activities of $1.0 million in the second quarter of 2007.

SECOND QUARTER RESULTS – From Continuing Operations

·TriMas reported record second quarter sales of $297.1 million, up 3.3% in comparison to $287.7 million in the second quarter 2007. Sales in the Packaging Systems, Energy Products and Industrial Specialties segments increased 1.3%, 29.6% and 6.4%, respectively. Sales in the RV & Trailer Products and Recreational Accessories segments declined 6.3% and 4.1%, respectively, due to lower demand as a result of reduced consumer discretionary spending and current economic conditions in the United States.

·The Company reported operating profit of $29.9 million for the second quarter 2008, in comparison to operating profit of $20.4 million in the second quarter 2007. Excluding the Special Items⁽¹⁾ detailed in Appendix II for both periods, second quarter 2008 operating profit would have been $32.1 million, as compared to $34.6 million in second quarter 2007. This decrease between years resulted primarily from demand declines in the businesses serving the recreational vehicle and trailer-related end markets.

·Adjusted EBITDA⁽²⁾ for the second quarter 2008 was $39.4 million, as compared to $28.9 million in the second quarter 2007. Excluding the impact of the Special Items⁽¹⁾, second quarter 2008 Adjusted EBITDA⁽²⁾ would have been $41.7 million, as compared to $43.1 million in the second quarter 2007, consistent with the decline in operating profit.

·The Company reported income from continuing operations of $9.4 million in the second quarter 2008, or $0.28 per diluted share, compared to a loss from continuing operations of $4.1 million, or $0.15 per diluted share in the second quarter 2007. Excluding the impact of Special Items⁽¹⁾, second quarter 2008 income from continuing operations would have improved 12.8% to $10.8 million, as compared to $9.6 million in the second quarter 2007.

·The Company reduced total indebtedness, including amounts utilized under its receivables securitization facility, by $23.4 million from March 31, 2008 to June 30, 2008. Aggregate availability under the Company’s revolving credit and receivables securitization facilities was $143.9 million as of June 30, 2008.

⁽¹⁾In evaluating the quality of the Company’s operating performance, management considers Adjusted EBITDA, among other metrics, as a key indicator of financial operating performance together with a careful review of results reported under GAAP. Appendix II details certain one-time costs, expenses and other charges, collectively described as “Special Items,” that are included in the determination of net income (loss) under GAAP and are not added back to net income (loss) in determining Adjusted EBITDA, but that management would consider important in evaluating the quality of the Company’s Adjusted EBITDA and operating results under GAAP.

⁽²⁾See Appendix I for reconciliation of Non-GAAP financial measure Adjusted EBITDA to the Company’s reported results of operations prepared in accordance with GAAP.

“In light of the current economic environment, our performance during the second quarter met our expectations,” said Grant H. Beard, TriMas’ President and Chief Executive Officer. “The diversity of our businesses and end markets remains a strength as the United States faces challenging economic times. During the quarter, our Energy Products segment reported significant growth in sales and operating profit of 29.6% and 51.8%, respectively, as a result of increased demand and new product introductions. Sales in our Industrial Specialties segment increased 6.4%, led by growth in our aerospace fastener business, while our Packaging Systems segment was up slightly compared to the prior year quarter. The Packaging Systems, Energy Products and Industrial Specialties segments collectively generated 77.4% of our segment operating profit during the quarter, and sales within this collection of businesses grew at a combined rate of 10.8% year over year.”

“Consistent with our first quarter results, our RV & Trailer Products and Recreational Accessories segments continue to face difficult end market conditions, resulting from the decline in consumer discretionary spending, consumer confidence and credit availability,” Beard continued. “While we estimate the end markets for these businesses are down approximately 15% to 20%, we believe we outperformed the market and our sales were down only 5%, as a result of market share gains, cross-selling, regional expansion and the introduction of new product content.”

“As we look forward across the remainder of 2008, we continue to execute pricing initiatives across our businesses to offset rising commodity costs,” Beard noted. “We expect continued weak end market demand within our RV & Trailer Products and Recreational Accessories businesses and have implemented actions in those businesses to reduce costs and decrease inventory to mitigate these economic pressures. We expect strength in our energy, aerospace and packaging businesses as we focus on launching new products and expanding geographically in growing end markets. We remain committed to aggressive cost reductions, working capital declines and the execution of pricing initiatives.”

Second Quarter Segment Results – From Continuing Operations

Packaging Systems - Sales for the second quarter of 2008 increased 1.3% compared to the prior year. Sales of industrial closures and specialty dispensing products, which comprised the majority of the sales in this segment, increased 7.6% in the second quarter 2008 and benefited from the favorable effects of currency exchange and pricing initiatives. This increase was partially offset by a significant decline in laminate and insulation product sales resulting from a weakening commercial construction end market. Operating profit for the quarter declined due to volume declines in laminate and insulation products and additional expenses associated with growth initiatives. The Company continues to diversify its product offering by developing specialty dispensing product applications for growing end markets, including pharmaceutical, personal care and food/beverage markets, and expanding geographically to generate long-term growth.

Energy Products - Sales increased 29.6% for the second quarter due to strong market demand and continued high utilization rates of refinery and petrochemical facilities. These trends, combined with the Company’s initiatives to service this market growth and gain additional share, resulted in increased

3

sales of engines and related parts, new compressors and gas production equipment products for use at well-sites, and specialty gaskets and related fastening hardware for the refinery and petrochemical industries. Operating profit for the quarter increased 51.8%, in line with higher sales volumes and as a result of favorable cost leverage. The Company plans to continue to launch new products to complement its engine business, while expanding its gasket business internationally.

Industrial Specialties - Sales for the second quarter increased 6.4% due to increased demand, most notably in the aerospace fastener business resulting from market share gains and strong overall market demand. This segment also benefited from sales growth in the industrial cylinder and defense businesses, and the August 2007 acquisition of a medical device manufacturer. Operating profit for the quarter increased slightly as the benefits of higher sales volumes were partially offset by increased expenditures to invest in growth initiatives and lower absorption of fixed costs in the specialty fittings business, as a result of lower production volumes. The Company plans to drive growth in this segment by developing specialty products for growing end markets such as medical and aerospace, while continuing to expand international sales efforts.

RV & Trailer Products - Sales for the second quarter declined a net 6.3%, as sales growth in the Australian business was more than offset by the continued weak demand in most end markets in the United States. Operating profit decreased 65.7% due to reduced sales volumes and lower absorption of fixed costs as the Company reduced its production to manage inventory levels, combined with a less favorable product sales mix. The Company’s focus in this segment is to aggressively manage costs and to leverage strong brand positions for increased market share, cross-sell the product portfolio into all channels and expand internationally.

Recreational Accessories - Sales decreased 4.1% for the second quarter, as the Company continued to experience weak consumer demand for towing accessories. Operating profit declined 11.8% as a result of lower sales volumes. The Company plans to continue to manage costs, increase market share in the United States and Canada, and pursue new market opportunities in select international markets.

Financial Position

The Company reduced total indebtedness, including amounts outstanding under its receivables securitization facility, by $23.4 million from March 31, 2008 to June 30, 2008. TriMas ended the quarter with total debt of $616.4 million and funding under its receivables securitization facility of $33.0 million for a total of $649.4 million. TriMas ended the quarter with cash of $6.9 million and $143.9 million of aggregate availability under its revolving credit and receivables securitization facilities.

Outlook

In its March 13, 2008 fourth quarter earnings release, TriMas provided a full year 2008 diluted earnings per share from continuing operations guidance range of $0.85 to $0.95 per share. The Company also provided a full year 2008 net income from continuing operations range of $28.5 million to $31.9 million. Second quarter results met the Company’s expectations, and 2008 guidance remains as previously announced, excluding the second quarter Special Items of $0.04 per diluted share related to charges associated with restructuring and cost reduction initiatives.

This outlook does not include the impact of any future unidentified restructuring charges and divestitures or acquisitions of operating assets that may occur from time to time due to management decisions and changing business circumstances. The outlook above also does not include the impact of

4

any potential future non-cash impairment charges of goodwill, intangibles and fixed assets. This outlook also excludes benefit costs related to contractual obligations to Metaldyne or discontinued operations. The Company is currently unable to forecast the likelihood of occurrence, timing and/or magnitude of any such amounts or events.

⁽¹⁾The Company defines Adjusted EBITDA as net income (loss) before cumulative effect of accounting change, interest, taxes, depreciation, amortization, non-cash asset and goodwill impairment write-offs, and non-cash losses on sale-leaseback of property and equipment.  Lease expense and non-recurring charges are included in Adjusted EBITDA and include both cash and non-cash charges related to restructuring and integration expenses.  In evaluating our business, management considers and uses Adjusted EBITDA as a key indicator of financial operating performance and as a measure of cash generating capability.  Management believes this measure is useful as an analytical indicator of leverage capacity and debt servicing ability, and uses it to measure financial performance as well as for planning purposes.  However, Adjusted EBITDA should not be considered as an alternative to net income, cash flow from operating activities or any other measures calculated in accordance with U.S. GAAP, or as an indicator of operating performance.  The definition of Adjusted EBITDA used here may differ from that used by other companies.
