TRIMAS CORPORATION REPORTS RECORD SECOND QUARTER RESULTS

Company Reports Growth in Sales of 12% and Income⁽¹⁾ of 20%

Company Reaffirms 2013 Outlook of $2.15 to $2.25 EPS

BLOOMFIELD HILLS, Michigan, July 25, 2013 - TriMas Corporation (NASDAQ: TRS) today announced financial results for the quarter ended June 30, 2013. The Company reported record second quarter net sales from continuing operations of $378.0 million, an increase of 11.7% compared to second quarter2012. Second quarter 2013 diluted earnings per share from continuing operations attributable to TriMas Corporation was $0.65, as compared to $0.44 during second quarter2012. Excluding Special Items⁽¹⁾, second quarter2013 diluted earnings per share from continuing operations would have been $0.69, a 13.1% improvement from $0.61 in second quarter2012.

TriMas Highlights

• Reported record second quarter net sales of $378.0 million, an increase of 11.7% as compared to second quarter2012, due to results from bolt-on acquisitions and the successful execution of numerous growth initiatives.

• Improved income from continuing operations attributable to TriMas Corporation⁽¹⁾ by 19.7%, excluding the impact of Special Items, compared to second quarter2012. Improved diluted earnings per share⁽¹⁾, while absorbing costs related to several acquisitions and approximately 6% higher weighted average shares outstanding for second quarter2013, as compared to second quarter2012.

• Completed five bolt-on acquisitions for approximately $47 million, net of cash acquired, or approximately one-times revenue acquired, through second quarter year to date to expand and globalize existing product offerings, gain access to new customers and end markets, expand the geographic footprint internationally, further enhance management capacity, and capitalize on scale and cost efficiencies.

• Reduced interest expense by more than 45% as compared with second quarter2012.

• Continued to invest in a flexible manufacturing footprint to optimize manufacturing costs long-term, add necessary capacity, enhance customer service and support future growth.

• Today announced the acquisition of substantially all of the assets of a towbar manufacturer located in Germany and Finland. These assets, combined with the April 2013 acquisition of C.P. Witter Limited, a leading manufacturer of highly-engineered towbars and cargo management products located in the United Kingdom, position Cequent to capitalize on growth opportunities in new markets through product and geographic expansion.

"Our second quarter results are as expected with 11.7% sales growth and a 19.7% increase in income from continuing operations attributable to TriMas Corporation⁽¹⁾ compared to second quarter 2012," said David Wathen, TriMas President and Chief Executive Officer. "In addition, we delivered a record second quarter$0.69 in diluted earnings per share from continuing operations (excluding Special Items)⁽¹⁾, while absorbing the effects related to several acquisitions and approximately 6% higher weighted average shares outstanding for second quarter2013, as compared to second quarter2012. We continued to effectively invest in future growth and productivity programs, and we successfully lowered our interest expense, reduced our tax rate and generated cash as planned."

"In the midst of a challenging global economic environment, we continue to identify the bright spots and successfully execute on new product introductions, geographic expansion and market share initiatives, as well as leverage our recent bolt-on acquisitions. These initiatives have contributed to our year-over-year sales increases in five of our six segments during the second quarter. We also continued with footprint consolidation projects within our Cequent segments, moving toward more efficient and flexible manufacturing facilities."

"In the short term, our margins are lower than our expected run rates due to the temporary costs related to our recent acquisitions, including diligence and integration costs, purchase accounting adjustments and lower initial margin rates of these businesses. We remain committed to increasing margins across our businesses and we will continue to

1

implement productivity and Lean programs throughout the organization, improve the margins of our acquired businesses and leverage our flexible manufacturing footprint."

"As we look to the second half of the year, we maintain a conservative macroeconomic outlook, while remaining confident in our ability to deliver our previous guidance for full year 2013," added Mark Zeffiro, TriMas Executive Vice President and Chief Financial Officer. "We remain committed to TriMas' ability to outperform the economy, with expected 2013 sales growth of 6% to 8%, as compared to 2012. We believe our initiatives for continued revenue growth, the structural cost actions being executed this year and on-going productivity projects position TriMas well for the balance of 2013. We are reaffirming our full year 2013 diluted earnings per share range of $2.15 and $2.25 per share, with the midpoint representing more than 19% EPS growth compared to 2012.”

Second Quarter Financial Results - From Continuing Operations

• TriMas reported record second quarter net sales of $378.0 million, an increase of 11.7% as compared to $338.4 million in second quarter2012. During second quarter, net sales increased in five of the six reportable segments, primarily as a result of additional sales from bolt-on acquisitions, market share gains, new product introductions, geographic expansion and increased market demand as compared to second quarter2012. More than half of the sales increase was due to organic growth, while the remainder was the result of recent acquisitions, partially offset by approximately $1.2 million of unfavorable currency exchange.

• The Company reported operating profit of $41.6 million in second quarter2013. Excluding Special Items⁽¹⁾ related to facility consolidation and relocation projects within Cequent, second quarter2013 operating profit would have been $43.6 million, as compared to $46.2 million during second quarter2012.Second quarter2013 operating profit and the related margin percentage were impacted by costs related to recent acquisitions including purchase accounting adjustments, higher costs associated with global growth initiatives and new plant and equipment ramp-up costs. The Company continued to generate significant savings from capital investments, productivity projects and Lean initiatives, which contributed to the funding of growth initiatives.

• Excluding noncontrolling interests related to Arminak & Associates, second quarter2013 income from continuing operations attributable to TriMas Corporation was $26.2 million, or $0.65 per diluted share, compared to income from continuing operations attributable to TriMas Corporation of $16.7 million, or $0.44 per diluted share, during second quarter2012. Excluding Special Items⁽¹⁾, second quarter2013 income from continuing operations attributable to TriMas Corporation would have been $27.6 million, an improvement of 19.7%, and diluted earnings per share from continuing operations would have been $0.69, a 13.1% improvement from second quarter2012, primarily due to lower interest expense, while absorbing approximately 6% higher weighted average shares outstanding.

• The Company reported Free Cash Flow (defined as Cash Flow from Operating Activities less Capital Expenditures) of $39.5 million for second quarter2013, compared to $19.3 million in second quarter2012. The Company reported a year to date Free Cash Flow use of $12.4 million for 2013, compared to a use of $31.5 million year to date 2012. The Company expects to generate between $40 million and $50 million in Free Cash Flow for 2013, while continuing to invest in capital expenditures, working capital investments in acquisitions and future growth and productivity programs.

• Through June 30, 2013, the Company invested $25.9 million in capital expenditures (included in Free Cash Flow above) primarily in support of future growth and productivity opportunities and $46.6 million, net of cash acquired, in bolt-on acquisitions.

Financial Position

As of June 30, 2013, TriMas reported total indebtedness of $480.7 million, as compared to $422.4 million as of December 31, 2012, and $506.2 million as of March 31, 2013. This increase from year end was primarily as a result of the seasonality related to higher working capital levels and the funding of five acquisitions during the first half of 2013. TriMas ended the second quarter with $198.1 million of cash and aggregate availability under its revolving credit and accounts receivable facilities.

Business Segment Results⁽²⁾ - From Continuing Operations

Packaging - (Consists of Rieke Corporation including Arminak & Associates, Innovative Molding and the foreign subsidiaries of Englass, Rieke Germany, Rieke China and Rieke Italia)

Net sales for second quarterincreased11.2% compared to the year ago period primarily due to increases in specialty systems product sales resulting from additional demand from North American and European dispensing customers, as well as new customer opportunities in Asia. In addition, sales of industrial closures, rings and levers increased.

2

Operating profit and the related margin percentage for the quarter increased primarily due to higher sales levels and savings from ongoing productivity and automation initiatives, both in the legacy and acquired businesses. The Company continues to develop specialty dispensing and closure applications for growing end markets, including personal care, cosmetic, pharmaceutical, nutrition and food/beverage, and expand into complementary products.

Energy - (Consists of Lamons including South Texas Bolt & Fitting, CIFAL, Gasket Vedações Técnicas and Wulfrun)

Second quarter net sales increased24.7% compared to the year ago period primarily due to increased sales to engineering and construction customers, recent acquisitions and higher sales levels from the European branches. Second quarter operating profit increased, while the related margin percentage decreased as incremental margin driven by increased sales and manufacturing productivity was more than offset by higher selling, general and administrative expenses in support of branch expansion and acquisition costs incurred during the second quarter of 2013. The Company continues to grow its sales and service branch network in support of its global customers. The Company acquired the assets of Tat Lee (Thailand) Ltd. in April 2013, a manufacturer and distributor of standard and specialty gaskets, in addition to the acquisitions of Gasket Vedações Técnicas Ltda of Brazil in January 2013 and Wulfrun Specialised Fasteners Limited of the United Kingdom in March 2013.

Aerospace & Defense - (Consists of Monogram Aerospace Fasteners, Martinic Engineering and NI Industries)

Net sales for the second quarterincreased22.8% compared to the year ago period primarily due to the acquisition of Martinic Engineering and higher sales levels in the blind bolt fastener product lines, partially offset by a decrease in sales from the defense business. Second quarter operating profit increased, while the related margin percentage decreased primarily due to the impact of Martinic, including purchase accounting adjustments, additional selling, general and administrative costs and a less favorable product mix, as well as new equipment and plant ramp-up costs in the legacy aerospace business during the second quarter of 2013. The Company continues to invest in this segment by developing and marketing highly-engineered products for aerospace applications, as well as bidding on new projects for defense customers.

Engineered Components - (Consists of Arrow Engine and Norris Cylinder)

Second quarter net sales decreased4.9% compared to the year ago period primarily due to lower demand for engines, gas compression products and other well-site content related to decreased levels of drilling activity and well completions as compared to second quarter 2012. However, sales of industrial cylinders increased primarily due to growth in international markets and continued domestic market share gains. Second quarter operating profit and the related margin percentage decreased compared to the prior year period primarily due to the decreased sales and lower fixed cost absorption in the engine business, which was partially offset by improvements in the industrial cylinder business. The Company continues to develop new products and expand its international sales efforts.

Cequent APEA -(Consists of Cequent operations in Australia, Asia, Europe and Africa)

The Company renamed its former Cequent Asia Pacific segment to Cequent APEA (Cequent Asia Pacific Europe Africa) effective in the second quarter of 2013 following the Company's recent acquisitions to more appropriately reflect the expanding geography covered by this segment.

Net sales for second quarterincreased34.1% compared to the year ago period, primarily due to the April 2013 acquisition of C.P. Witter in the United Kingdom, the July 2012 acquisition of Trail Com and various growth initiatives in Asia and South Africa. Second quarter operating profit decreased after Special Items, and the related margin percentage decreased primarily as the profit earned on the increased sales levels was offset by costs related to the acquisitions including purchase accounting adjustments and higher selling, general and administrative expenses associated with the recent acquisitions. The Company continues to focus on reducing fixed costs and leveraging Cequent's strong brand positions. Today, the Company announced the acquisition of substantially all of the assets of a towbar manufacturer located in Germany and Finland which enables the Company to continue to capitalize on growth opportunities in new markets.

Cequent Americas -(Consists of Cequent Performance Products and Cequent Consumer Products with operations in North and South America)

Net sales for second quarterincreased7.0% compared to the year ago period, resulting primarily from increased sales within the retail, auto original equipment and aftermarket channels, as well as the sales related to the July 2012 acquisition of Engetran in Brazil. Second quarter operating profit and the related margin percentage decreased compared to the prior year period, as a result of a less favorable product sales mix and increase in selling, general and administrative expenses in support of growth initiatives. The Company continues to reduce fixed costs and leverage Cequent's strong brand positions and new products for increased market share in the United States and faster growing markets.
