In comparison, third quarter 2008 income from continuing operations was $8.1 million, or $0.24 per diluted share, including a ($0.01) per share impact of severance and business restructuring costs. The Company reduced total indebtedness, including amounts outstanding under its receivables securitization facility, by $22.0 million compared to June 30, 2009 and by $101.4 million compared to September 30, 2008.

TriMas Third Quarter Business Highlights

·                 Continued to execute its $30 million Profit Improvement Plan (PIP) ahead of schedule with over $9 million in cost reductions realized during the quarter.

·                 Improved operating profit margin (excluding the impact of Special Items) by 280 basis points compared to second quarter 2009 and by 50 basis points compared to third quarter 2008.

·                 In the Packaging segment, grew specialty dispensing and new product sales by approximately 40% compared to the third quarter of 2008. These products are designed for end markets such as pharmaceutical, medical, personal care and food/beverage.

·                 Continued to demonstrate improvements in Cequent with an increase in operating profit margin (excluding the impact of Special Items) of 560 basis points, compared to third quarter 2008.

·                 Launched a strategic sourcing initiative across the businesses to drive additional synergies and productivity.

“We are executing on our productivity, working capital and growth initiatives,” said David Wathen, TriMas President and Chief Executive Officer. “Compared to last quarter, we improved operating profit margin by 280 basis points on slightly lower revenues, decreased operating working capital by almost $23 million and generated over $43 million of free cash flow. Sales and end market demand are still down, but we are using this environment to make TriMas a permanently better business.”

“As we move forward, we will continue our focus on reducing costs and working capital in each business segment,” Wathen continued. “We remain focused on debt reduction and the protection of our liquidity. During the quarter, we reduced total indebtedness by $22 million and ended the quarter with almost $25 million in cash. While we are pleased with the progress we are making across these initiatives, there is more work to be done.”

“For the full year of 2009, we continue to anticipate revenue to be down 20% to 25% compared to 2008, consistent with our comments last quarter. We are allocating some resources to key growth initiatives aimed at expanding end markets and geographies. We are also beginning to see positive signs in some of our businesses, as our Packaging and Cequent segments project fourth quarter 2009 revenues close to fourth quarter 2008 levels.

These developments lead us to expect at least modest revenue gains for next year. We are, however, continuing to operate our company with the realization we are still in a time of economic uncertainty. We are committed to maintaining cushion on our bank covenants, delevering TriMas and ensuring liquidity for our future endeavors,” Wathen concluded.

Third Quarter Financial Results — From Continuing Operations

·                 TriMas reported third quarter net sales of $203.7 million, a decrease of 21.9% in comparison to $260.7 million in the third quarter 2008. Although several businesses benefited from new product introductions and new sales promotions, sales in all five segments declined in comparison to the prior year third quarter. The sales declines were primarily due to reductions in volume as a result of continued weak global economic activity and reduced consumer discretionary spending. Net sales were also negatively impacted by approximately $3.1 million due to unfavorable currency exchange.

·                 The Company reported operating profit of $20.2 million for the third quarter 2009, a decrease of 26.7% compared to operating profit of $27.5 million for the third quarter 2008. Despite this decline, which was driven by the decrease in sales, operating profit margin, excluding the impact of Special Items, would have increased from 10.8% of sales during the third quarter of 2008 to 11.3% of sales during the third quarter of 2009. This improvement was a result of the Company’s cost reduction and productivity initiatives, with the largest positive impact experienced in the Packaging and Cequent segments.

·                 Adjusted EBITDA(2) for the third quarter 2009 decreased 14.2% to $31.9 million, as compared to $37.2 million in the third quarter 2008. Management’s actions, however, enabled the Company to achieve an increase in Adjusted EBITDA margin from 14.3% during the third quarter of 2008 to 15.7% during the third quarter of 2009.

·                 Income from continuing operations for the third quarter 2009 decreased 19.2% to $6.5 million, or $0.19 per diluted share, compared to income from continuing operations of $8.1 million, or $0.24 per diluted share, in the third quarter 2008. These results include the after-tax impact of Special Items of $1.8 million, or ($0.05) per diluted share, and gain on extinguishment of debt of $0.7 million, or $0.02 per diluted share, in the third quarter of 2009 and the after-tax impact of Special Items of $0.4 million, or ($0.01) per diluted share, in the third quarter of 2008.

·                 Free Cash Flow(2) for third quarter 2009 increased 85.3% to $43.4 million from $23.4 million during the third quarter of 2008, driven by improvements in net working capital resulting from reduced inventory and accounts receivables levels.

·                  The Company continued to focus on its Profit Improvement Plan (PIP) to achieve over $30 million in cost savings during 2009 and is on plan to exceed these cost savings. TriMas realized over $9 million in cost reductions and incurred approximately $2.9 million in cash and non-cash charges related to its PIP during the third quarter of 2009. The Company has substantially completed the elimination of the production and distribution functions in Mosinee, Wisconsin as of September 30, 2009, and expects to fully complete the move of these operations by December 31, 2009. The Company continues to pursue additional fixed and variable cost saving actions and productivity initiatives.

the third quarter of 2009, the Company retired approximately $10.0 million face value of the Company’s senior subordinated notes in open market transactions for approximately $8.7 million.

The Company does not have any significant debt maturities under its credit agreement or subordinated notes until 2012.  As of September 30, 2009, the Company was in compliance with all debt covenants.

Business Segment Results — From Continuing Operations

Packaging — Sales for the third quarter decreased 8.4% compared to the year ago period, due primarily to a decline in industrial closure product sales resulting from the overall economic slowdown, partially offset by the growth in specialty dispensing product sales and the launch of other new products. Sales were also negatively impacted by the unfavorable effects of currency exchange. Despite the decrease in sales, operating profit for the quarter increased due to lower material costs and reduced selling, general and administrative costs associated with the Company’s cost reduction plans, partially offset by the decline in industrial product sales and the unfavorable effects of currency exchange. As a result of the cost reduction actions, operating profit as a percentage of sales improved approximately 400 basis points compared to the third quarter of 2008. 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 — Third quarter sales decreased 35.1% compared to the year ago period due primarily to reduced demand for engines and other well-site content, resulting from a reduction in drilling activity and the deferred completion of previously drilled wells in North America. Sales in the Energy segment were also negatively impacted due to lower sales of specialty gaskets and related fastening hardware, as a result of decreased levels of turn-around activity at petrochemical refineries and reduced demand from the chemical industry. Operating profit for the quarter decreased as a result of lower sales volumes and related lower absorption of fixed costs, partially offset by reductions in discretionary spending. The Company continues to launch new well-site products to complement its engine business, while continuing to expand its sales and service branch network for the specialty gasket business, in anticipation of improvements in underlying demand in both of these businesses.

Aerospace & Defense — Sales for the third quarter decreased 34.6% compared to the year ago period due primarily to lower blind-bolt fastener sales resulting from program delays at commercial airframe manufacturers and inventory reductions at distribution customers, partially offset by sales of new products which increased the Company’s content on certain aircraft. Sales in the defense business were also lower compared to the year ago period, due to the lack of cartridge case sales resulting from the ongoing relocation of the defense facility, partially offset by new product sales and revenue associated with managing the facility relocation and closure. Operating profit for the quarter decreased primarily due to lower sales volumes, partially offset by a more favorable product sales mix and reduced selling, general and administrative expenses. The Company continues to develop and market highly-engineered products for the aerospace market, as well as expand its offerings to military and defense customers.

Engineered Components — Third quarter sales declined 54.3% compared to the year ago period due to demand declines in the Company’s industrial cylinder, precision cutting tools and medical device businesses, primarily as a result of the current economic downturn. Sales in the specialty fittings business increased slightly due to new product offerings. Operating profit for the quarter decreased due to lower sales volumes and lower absorption of fixed costs, which were partially offset by reduced selling, general and administrative expenses. The Company continues to develop specialty products for growing end markets such as medical and expand its international sales efforts.

Cequent — Sales decreased 6.5% for the third quarter compared to the year ago period. The Company continued to experience weak, but improving, consumer demand for heavy-duty towing, trailer and electrical products, as a result of uncertain economic conditions and reductions in consumer discretionary spending, and the unfavorable

effects of currency exchange, partially offset by a slight increase in sales in the Australia/Asia Pacific business. Operating profit for the quarter improved as a result of cost reductions implemented as part of the Company’s Profit Improvement Plan, partially offset by lower sales volumes, unfavorable foreign currency exchange and lower absorption of fixed costs. Due to the cost reduction actions, operating profit as a percentage of sales also improved approximately 560 basis points compared to the third quarter of 2008. The segment was negatively impacted by $2.1 million in charges associated with the closure of its Mosinee, Wisconsin manufacturing facility and other business restructuring costs. The Company continues to aggressively reduce fixed costs, decrease working capital and leverage strong brand positions for increased market share.

Reconciliation of Non-GAAP Measure Adjusted EBITDA(1) and Free Cash Flow(2)

(Unaudited)

(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.

(2)       The Company defines Free Cash Flow as Adjusted EBITDA from continuing operations, plus Special Items and net proceeds from sale of businesses, less cash paid for interest, taxes and Special Items, capital expenditures, changes in operating working capital and non-cash (gains) losses on debt extinguishment. As detailed in Appendix I, for purposes of determining Free Cash Flow, Special Items, net, include those one-time costs, expenses and other charges incurred on a cash basis 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 Free Cash Flow, as defined.
