Forward-Looking Statements

This report contains forward-looking statements (as that term is defined by the federal securities laws) about our financial condition, results of operations and business. You can find many of these statements by looking for words such as "may," "will," "expect," "anticipate," "believe," "estimate" and similar words used in this report.

These forward-looking statements are subject to numerous assumptions, risks and uncertainties. Because the statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by the forward-looking statements. We caution readers not to place undue reliance on the statements, which speak only as of the date of this report.

The cautionary statements set forth above should be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue. We do not undertake any obligation to review or confirm analysts' expectations or estimates or to release publicly any revisions to any forward-looking statement to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated events.

You should carefully consider the factors discussed in Part I, Item 1A, "Risk Factors," in our Annual Report on Form 10-K for the year ended December 31, 2013, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deemed to be immaterial also may materially adversely affect our business, financial position and results of operations or cash flows.

We disclose important factors that could cause our actual results to differ materially from our expectations under Part I, Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations," and elsewhere in this report. These cautionary statements qualify all forward-looking statements attributed to us or persons acting on our behalf. When we indicate that an event, condition or circumstance could or would have an adverse effect on us, we mean to include effects upon our business, financial and other conditions, results of operations, prospects and ability to service our debt.

TRIMAS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Basis of Presentation

TriMas Corporation ("TriMas" or the "Company"), and its consolidated subsidiaries, is a global manufacturer and distributor of products for commercial, industrial and consumer markets. The Company is principally engaged in the following reportable segments with diverse products and market channels: Packaging, Energy, Aerospace, Engineered Components, Cequent Asia Pacific Europe Africa ("Cequent APEA") and Cequent Americas. The Company renamed its former "Aerospace & Defense" reportable segment "Aerospace" effective in the third quarter of 2014 following the cessation of operations of NI Industries. See Note 5, "Discontinued Operations," for further information. See Note 14, "Segment Information," for further information on each of the Company's reportable segments.

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries and, in the opinion of management, contain all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of financial position and results of operations. Results of operations for interim periods are not necessarily indicative of results for the full year. The accompanying consolidated financial statements and notes thereto should be read in conjunction with the Company's 2013 Annual Report on Form 10-K.

2. New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-9, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-9"). ASU 2014-9 requires that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-9 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early adoption prohibited. The Company is in the process of assessing the impact of the adoption of ASU 2014-09 on its consolidated financial statements.

In April 2014, the FASB issued ASU 2014-8, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-8"). ASU 2014-8 changes the criteria for reporting discontinued operations and requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations. ASU 2014-8 is effective for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods, and interim periods within those years, beginning on or after December 15, 2014, with early adoption permitted for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company expects to adopt ASU 2014-08 upon its required effective date.

3. Equity Offering

In September 2013, the Company issued 5,175,000 shares of its common stock via a public offering at a price of $35.40 per share. Net proceeds from the offering, after deducting underwriting discounts, commissions and offering expenses of approximately $8.5 million, totaled approximately $174.7 million. The Company used the net offering proceeds for general corporate purposes, including retirement of debt in connection with the Company's October 2013 refinancing, acquisitions, capital expenditures and working capital requirements.

4. Facility Closures and Sale of Business

Facility Closures

Goshen, Indiana facility

In November 2012, the Company announced plans to close its manufacturing facility in Goshen, Indiana, moving production from Goshen to lower-cost manufacturing facilities during 2013. The Company completed the move and ceased operations in Goshen during the fourth quarter of 2013. During 2013, the Company recorded charges, primarily for severance benefits for its approximately 350 union hourly workers to be involuntarily terminated, of approximately $4.0 million, of which $3.8 million was recorded in the three months ended March 31, 2013 and is included in cost of sales in the accompanying consolidated statement of income. Additionally, during 2012, the Company recorded charges of approximately $1.2 million, primarily for severance benefits for salaried employees to be involuntarily terminated as part of the closure. As of September 30, 2014, the hourly and salaried severance benefits have been fully paid.

(unaudited)

In addition, during the three and nine months ended September 30, 2013, the Company incurred approximately $0.5 million and $1.2 million, respectively, of pre-tax non-cash charges related to accelerated depreciation expense as a result of shortening the expected lives on certain machinery, equipment and leasehold improvement assets that the Company no longer utilizes following the facility closure.

São Paulo, Brazil facility

In June 2014, the Company announced the restructuring of its Brazilian business within the Energy reportable segment, including plans to close its manufacturing facility in São Paulo, Brazil by the end of 2014. In connection with this action, the Company recorded charges of approximately $0.5 million, primarily related to severance benefits, which is included in cost of sales in the accompanying consolidated statement of income, for its approximately 60 employees to be involuntarily terminated as a result of this closure.

The Company's manufacturing facility in São Paulo is subject to a lease agreement expiring in 2022. The Company is currently assessing the potential recoverability of its future lease obligations for this facility, and will record an estimate of any future unrecoverable lease obligations upon the cease-use date of the facility.

Sale of Business

On August 5, 2013, the Company announced the sale of its business in Italy within the Packaging reportable segment for cash of approximately $10.3 million. As a result, the Company recorded a pre-tax gain of approximately $10.5 million, of which $7.9 million related to the release of historical currency translation adjustments into income.

5. Discontinued Operations

During the third quarter of 2014, the Company ceased operations of its NI Industries business. NI Industries manufactured cartridge cases for the defense industry and was party to a U.S. Government facility maintenance contract. The Company received approximately $6.7 million for the sale of certain intellectual property and related inventory and tooling. This amount is included in the income from discontinued operations in the accompanying consolidated statement of income.

During the fourth quarter of 2011, the Company sold its precision tool cutting and specialty fittings lines of business, both of which were part of the Engineered Components reportable segment. The purchase agreement included up to $2.5 million of contingent consideration based on achievement of certain levels of financial performance in 2012 and 2013. During the second quarter of 2013, the Company was paid approximately $1.0 million of a possible $1.3 million as payout for the 2012 financial performance criteria. This amount is included in the income from discontinued operations in the accompanying consolidated statement of income. No payout was received in 2014, as the 2013 financial performance criteria were not met.

The results of the aforementioned businesses are reported as discontinued operations for all periods presented. Results of discontinued operations are summarized as follows:

	Three months ended September 30,						Nine months ended September 30,
	2014			2013			2014			2013

Vietnam, Lion Holdings specializes in the manufacture of highly engineered dispensing solutions and generated approximately $10 million in revenue for the twelve months ended June 30, 2014.

During the first nine months of 2013, the Company completed acquisitions for an aggregate amount of approximately $56 million, net of cash acquired. Of these acquisitions, the most significant are as follows:

• Martinic Engineering, Inc. ("Martinic") within the Company's Aerospace reportable segment is a manufacturer of highly-engineered, precision machined, complex parts for commercial and military aerospace applications, including auxiliary power units, as well as electrical, hydraulic and pneumatic systems located in the United States and generated approximately $13 million in revenue for the twelve months ended December 31, 2012.

• Wulfrun Specialised Fasteners Limited ("Wulfrun") within the Company's Energy reportable segment is a manufacturer and distributor of specialty bolting and CNC machined components for use in critical oil and gas, pipeline and power generation applications located in the United Kingdom and generated approximately $10 million in revenue for the twelve months ended December 31, 2012.

• C.P. Witter Limited ("Witter"), within the Company's Cequent APEA reportable segment, is a manufacturer of highly-engineered towbars and accessories which are distributed through a wide network of commercial dealers located in the United Kingdom, and generated approximately $20 million in revenue for the twelve months ended March 31, 2013.

• The towing technology and business assets of AL-KO GmbH ("AL-KO"), located in both Germany and Finland, and also within the Company's Cequent APEA reportable segment. The acquired assets generated approximately $16 million of revenue for the twelve months ended June 30, 2013. The fair value of the AL-KO net assets exceeded the purchase price, resulting in a bargain purchase gain of approximately $2.9 million, which is included in other income (expense), net in the accompanying consolidated statement of income for the three and nine months ended September 30, 2013.

The results of operations of the aforementioned acquisitions are not significant compared to the overall results of operations of the Company.

7. Arminak & Associates

During the first quarter of 2012, the Company acquired 70% of the membership interests of Arminak & Associates, LLC ("Arminak") for the purchase price of approximately $67.7 million, which is included in the Company's Packaging reportable segment. The original purchase agreement provided the Company an option to purchase, and Arminak's previous owners an option to sell, the remaining 30% noncontrolling interest at specified dates in the future based on a multiple of future earnings, as defined in the purchase agreement. The put and call options become exercisable during the first quarters of 2014, 2015 and 2016, and the original combination of a noncontrolling interest and a redemption feature resulted in a redeemable noncontrolling interest, which was classified outside of permanent equity on the accompanying consolidated balance sheet.

On March 11, 2014, in lieu of the put and call options in the original purchase agreement, the Company entered into a new agreement to purchase the entire 30% noncontrolling interest in Arminak for a cash purchase price of $51.0 million. The purchase agreement also includes additional contingent consideration of up to $7.0 million, with the amount to be earned based on the achievement of certain levels of 2015 financial performance. In order to estimate the fair value of the contingent consideration, the Company utilized the Monte Carlo valuation method, using variations of expected future payouts given certain significant assumptions including expected revenue and earnings growth, volatility and risk. As these assumptions are not observable in the market, the calculation represents a Level 3 fair value measurement. As of September 30, 2014, the estimated liability for the payout of contingent consideration is $3.1 million. The final contingent consideration is expected to be paid, if earned, in the second quarter of 2016.

As part of purchasing the remaining membership interest, the Company finalized the calculation of the redeemable noncontrolling interest as of March 11, 2014. Changes in the carrying amount of redeemable noncontrolling interest are summarized as follows:

	Noncontrolling interest
	(dollars in thousands)
Beginning balance, December 31, 2013	$	29,480
Distributions to noncontrolling interests	(580		)
Net income attributable to noncontrolling interests	810
Ending balance, March 11, 2014	$	29,710

The difference between the cash purchase price and final redeemable noncontrolling interest as of March 11, 2014 was recorded as a reduction in paid in capital, net of tax, as included in the accompanying consolidated statement of shareholders' equity.

8. Goodwill and Other Intangible Assets

During the third quarter of 2014, based on a few consecutive quarters of revenue and earnings declines compared to historical levels within the Company's Energy reporting unit, the Company determined that there were indicators of a decline in fair value of the Energy reporting unit, which also may indicate a potential impairment of the recorded goodwill. As such, the Company conducted a Step 1 quantitative goodwill impairment analysis as required by the authoritative accounting literature. The Company utilized both income and market-based approaches, placing a 75% and 25% weighting on each, respectively. Significant management assumptions used under the income approach were a weighted average cost of capital of 13% and an estimated residual growth rate of 3%. In considering the weighted average cost of capital for the reporting unit, management considered the level of risk inherent in the cash flow projections based on historical attainment of its projections and current market conditions. Upon completion of the goodwill impairment test, the Company determined that the fair value of the Energy reporting unit exceeded the carrying value by more than 20%, and thus there was no goodwill impairment. In addition, a 1% reduction in residual growth rate combined with a 1% increase in the weighted average cost of capital would not have changed the conclusions reached under the Step I impairment test.

Changes in the carrying amount of goodwill for the nine months ended September 30, 2014 are summarized as follows:

Credit Agreement

The Company is a party to a credit agreement consisting of a $575.0 million senior secured revolving credit facility, which matures in October 2018 and is subject to interest at London Interbank Offered Rates ("LIBOR") plus 1.50%, and a $175.0 million senior secured term loan A facility, which matures in October 2018 and is subject to interest at LIBOR plus 1.50% (collectively, the "Credit Agreement"). The interest rate spread is based upon the leverage ratio, as defined, as of the most recent determination date. Per the Credit Agreement, the senior secured revolving credit facility permits borrowings denominated in specific foreign currency ("Foreign Currency Loans"), subject to a $75.0 million sub limit.

The Credit Agreement also provides incremental term loan and/or revolving credit facility commitments in an amount not to exceed the greater of $300.0 million and an amount such that, after giving effect to such incremental commitments and the incurrence of any other indebtedness substantially simultaneously with the making of such commitments, the senior secured net leverage ratio, as defined, is no greater than 2.50 to 1.00. The terms and conditions of any incremental term loan and/or revolving credit facility commitments must be no more favorable than the existing credit facility.

Beginning with the fiscal year ending December 31, 2014 (payable in 2015), the Company may be required to prepay a portion of its term loan A facility in an amount equal to a percentage of the Company's excess cash flow, as defined, with such percentage based on the Company's leverage ratio, as defined.

The Company is also able to issue letters of credit, not to exceed $75.0 million in aggregate, against its revolving credit facility commitments. At September 30, 2014 and December 31, 2013, the Company had letters of credit of approximately $21.9 million and $24.1 million, respectively, issued and outstanding.

At September 30, 2014, the Company had $103.0 million outstanding under its revolving credit facility and had $452.1 million potentially available after giving effect to approximately $21.9 million of letters of credit issued and outstanding. AtDecember 31, 2013, the Company had$71.1 millionoutstanding under its revolving credit facility and had$479.8 million potentially available after giving effect to approximately $24.1 million of letters of credit issued and outstanding. However, including availability under its accounts receivable facility and after consideration of leverage restrictions contained in the Credit Agreement, the Company had $366.7 million and $360.3 million at September 30, 2014 and December 31, 2013, respectively, of borrowing capacity available for general corporate purposes.

The debt under the Credit Agreement is an obligation of the Company and certain of its domestic subsidiaries and is secured by substantially all of the assets of such parties. Borrowings under the $75.0 million foreign currency sub limit of the $575.0 million senior secured revolving credit facility are secured by a pledge of the assets of the foreign subsidiary borrowers that are a party to the agreement.  The Credit Agreement also contains various negative and affirmative covenants and other requirements affecting the Company and its subsidiaries, including restrictions on incurrence of debt, liens, mergers, investments, loans, advances, guarantee obligations, acquisitions, assets dispositions, sale-leaseback transactions, hedging agreements, dividends and other restricted payments, transactions with affiliates, restrictive agreements and amendments to charters, bylaws, and other material documents. The terms of the Credit Agreement also require the Company and its subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a maximum leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined) and a minimum interest expense coverage ratio (consolidated EBITDA, as defined, over cash interest expense, as defined). At September 30, 2014, the Company was in compliance with its financial and other covenants contained in the Credit Agreement.

As of September 30, 2014 and December 31, 2013, the Company's Credit Agreement traded at approximately 99.2% and 99.8% of par value, respectively. The valuations of the Credit Agreement were determined based on Level 2 inputs under the fair value hierarchy, as defined.

Receivables Facility

The Company is a party to an accounts receivable facility through TSPC, Inc. ("TSPC"), a wholly-owned subsidiary, to sell trade accounts receivable of substantially all of the Company's domestic business operations. During the second quarter of 2014, the Company amended this $105.0 million facility, reducing the usage fee on amounts outstanding previously ranging from 1.20% or 1.35%, depending on the amounts drawn under the facility, to 1.15%. The amendment also reduced the cost of the unused portion of the facility from 0.40% to 0.35% and extended the maturity date from October 12, 2017 to October 16, 2018.

Under this facility, TSPC, from time to time, may sell an undivided fractional ownership interest in the pool of receivables up to approximately $105.0 million to a third party multi-seller receivables funding company. The net amount financed under the facility is less than the face amount of accounts receivable by an amount that approximates the purchaser's financing costs. The cost of funds under this facility consisted of a 3-month LIBOR-based rate plus a usage fee of 1.15% and 1.20% as of September 30, 2014 and 2013, respectively, and a fee on the unused portion of the facility of 0.35% and 0.40% as of September 30, 2014 and 2013, respectively.

The Company had $66.3 million and $57.0 million outstanding under the facility as of September 30, 2014 and December 31, 2013, respectively, and $27.1 million and $20.2 million, respectively, available but not utilized. Aggregate costs incurred under the facility were $0.3 million and $0.4 million for the three months ended September 30, 2014 and 2013, respectively, and $1.0 million and $1.1 million for the nine months ended September 30, 2014 and 2013, respectively, and are included in interest expense in the accompanying consolidated statement of income. The facility expires on October 16, 2018.

The cost of funds fees incurred are determined by calculating the estimated present value of the receivables sold compared to their carrying amount. The estimated present value factor is based on historical collection experience and a discount rate based on a 3-month LIBOR-based rate plus the usage fee discussed above and is computed in accordance with the terms of the securitization agreement. As of September 30, 2014, the cost of funds under the facility was based on an average liquidation period of the portfolio of approximately 1.7 months and an average discount rate of 1.8%.

Other Bank Debt

The Company's Australian subsidiary is party to a debt agreement which matures on October 31, 2014 and is secured by substantially all the assets of the subsidiary. At September 30, 2014 and December 31, 2013, the balance outstanding under this agreement was approximately $2.2 million and $0.7 million, respectively, at an average interest rate of 4.6% at each of the periods then ended.

In the second quarter of 2014, the Company's Dutch subsidiary entered into a credit agreement consisting of a $12.5 million uncommitted working capital facility agreement which matures on May 29, 2015, is subject to interest at LIBOR plus 2.75% per annum and is guaranteed by TriMas. In addition, this Dutch subsidiary is subject to an overdraft facility in conjunction with the uncommitted working capital facility up to $1.0 million, subject to interest at U.S. dollar prime rate plus 0.75%. No amounts were outstanding on this facility as of September 30, 2014.

12. Derivative Instruments

Foreign Currency Exchange Rate Risk

As of September 30, 2014, the Company was party to forward contracts to hedge changes in foreign currency exchange rates with notional amounts of approximately $11.0 million. The Company uses foreign currency forward contracts to mitigate the risk associated with fluctuations in currency rates impacting cash flows related to certain payments for contract manufacturing in its lower-cost manufacturing facilities. The foreign currency forward contracts hedge currency exposure between the Mexican peso and the U.S. dollar and the Thai baht and the Australian dollar and mature at specified monthly settlement dates through March 2015. At inception, the Company designated the foreign currency forward contracts as cash flow hedges.

Interest Rate Risk

In December 2012, the Company entered into an interest rate swap agreement to fix the LIBOR-based variable portion of the interest rates on its term loan A facility. The term loan A swap agreement fixes the LIBOR-based variable portion of the interest rate, beginning February 2013, on a total of $175.0 million notional amount at 0.74% and expires on October 11, 2017. At inception, the Company designated the swap agreement as a cash flow hedge.

13. Commitments and Contingencies

Asbestos

As of September 30, 2014, the Company was a party to 1,105 pending cases involving an aggregate of 8,001 claimants alleging personal injury from exposure to asbestos containing materials formerly used in gaskets (both encapsulated and otherwise) manufactured or distributed by certain of the Company's subsidiaries for use primarily in the petrochemical refining and exploration industries. The following chart summarizes the number of claimants, number of claims filed, number of claims dismissed, number of claims settled, the average settlement amount per claim and the total defense costs, exclusive of amounts reimbursed under the Company's primary insurance, at the applicable date and for the applicable periods:

	Claims pending at beginning of period	Claims filed during period	Claims dismissed during period	Claims settled during period	Average settlement amount per claim during period		Total defense costs during period
Fiscal Year Ended December 31, 2013	7,880	360	226	39	$	8,294	$	2,620,000
Nine Months Ended September 30, 2014	7,975	151	103	22	$	8,973	$	1,987,000

In addition, the Company acquired various companies to distribute its products that had distributed gaskets of other manufacturers prior to acquisition. The Company believes that many of its pending cases relate to locations at which none of its gaskets were distributed or used.

The Company may be subjected to significant additional asbestos-related claims in the future, the cost of settling cases in which product identification can be made may increase, and the Company may be subjected to further claims in respect of the former activities of its acquired gasket distributors. The Company is unable to make a meaningful statement concerning the monetary claims made in the asbestos cases given that, among other things, claims may be initially made in some jurisdictions without specifying the amount sought or by simply stating the requisite or maximum permissible monetary relief, and may be amended to alter the amount sought. The large majority of claims do not specify the amount sought. Of the 8,001 claims pending at September 30, 2014, 102 set forth specific amounts of damages (other than those stating the statutory minimum or maximum). Below is a breakdown of the amount sought for those claims seeking specific amounts:

	Compensatory & Punitive			Compensatory Only			Punitive Only
Range of damages sought (in millions)	$0.0 to $5.0	$5.0 to $10.0	$10.0+	$0.0 to $0.6	$0.6 to $5.0	$5.0+	$0.0 to $2.5	$2.5 to $5.0	$5.0+
Number of claims	76	13	13	26	57	19	94	7	1

In addition, relatively few of the claims have reached the discovery stage and even fewer claims have gone past the discovery stage.

Total settlement costs (exclusive of defense costs) for all asbestos-related cases, some of which were filed over 20 years ago, have been approximately $6.8 million. All relief sought in the asbestos cases is monetary in nature. To date, approximately 40% of the Company's costs related to settlement and defense of asbestos litigation have been covered by its primary insurance. Effective February 14, 2006, the Company entered into a coverage-in-place agreement with its first level excess carriers regarding the coverage to be provided to the Company for asbestos-related claims when the primary insurance is exhausted. The coverage-in-place agreement makes asbestos defense costs and indemnity coverage available to the Company that might otherwise be disputed by the carriers and provides a methodology for the administration of such expenses. Nonetheless, the Company believes it is likely there will be a period within the next one or two years, prior to the commencement of coverage under this agreement and following exhaustion of the Company's primary insurance coverage, during which the Company will be solely responsible for defense costs and indemnity payments, the duration of which would be subject to the scope of damage awards and settlements paid.

Based on the settlements made to date and the number of claims dismissed or withdrawn for lack of product identification, the Company believes that the relief sought (when specified) does not bear a reasonable relationship to its potential liability. Based upon the Company's experience to date, including the trend in annual defense and settlement costs incurred to date, and other available information (including the availability of excess insurance), the Company does not believe these cases will have a material adverse effect on its financial position and results of operations or cash flows.

Ordinary Course Claims

The Company is subject to other claims and litigation in the ordinary course of business, but does not believe that any such claim or litigation will have a material adverse effect on its financial position and results of operations or cash flows.

The Company did not incur significant stock-based compensation expense related to stock options during the nine months ended September 30, 2014 and 2013.

Restricted Shares

The Company awarded 600 restricted stock grants to certain employees during the third quarter of 2014. These shares are subject only to a service condition and vest on the first anniversary date of the award so long as the employee remains with the Company.

During the nine months ended September 30, 2014, the Company issued 7,409 shares related to director fee deferrals. The Company allows for its non-employee independent directors to make an annual election to defer all or a portion of their directors fees and to receive the deferred amount in cash or equity. Certain of the Company's directors have elected to defer all or a portion of their directors fees and to receive the amount in Company common stock at a future date.

The Company also awarded multiple restricted stock grants during the first quarter of 2014. First, the Company granted 23,226 restricted shares of common stock to certain employees which are subject only to a service condition and vest ratably over three years so long as the employee remains with the Company.

The Company awarded 40,837 restricted shares of common stock to certain employees during thefirst quarter of 2014. These shares are subject only to a service condition and vest on the first anniversary date of the award. The awards were made to participants in the Company's short-term incentive compensation plan ("STI"), where all STI participants whose target annual award exceeds $20 thousand receive 80% of the value in earned cash and 20% in the form of a restricted stock award upon finalization of the award amount in the first quarter each year following the previous plan year.

The Company awarded243,124 restricted shares of common stock to certain Company key employees during thefirst quarter of 2014. Half of the restricted shares granted are service-based restricted stock units. These awards vest ratably over three years. The other half of the shares are subject to a performance condition and are earned based upon the achievement of two performance metrics over a period of three calendar years, beginning on January 1, 2014 and ending on December 31, 2016. Of this award, 75% of the awards are earned based upon the Company's earnings per share ("EPS") cumulative average growth rate ("EPS CAGR") over the performance period. The remaining 25% of the grants are earned based upon the Company's three-year average return on invested capital ("ROIC"). ROIC is defined as the Company's after-tax operating profit, as publicly reported by the Company, plus or minus special items that may occur from time-to-time, divided by the Company's last five-quarter average of invested capital. Invested capital is comprised of the Company's long-term debt plus shareholders' equity plus non-controlling interest, less cash held. Depending on the performance achieved for these two metrics, the amount of shares earned can vary from 30% of the target award to a maximum amount of 200% of the target award for the ROIC metric and 250% of the target award for the EPS CAGR metric. However, if these performance metrics are not achieved, no award will be earned. The performance awards vest on a "cliff" basis at the end of the three-year performance period.

In addition, the Company granted 20,832 restricted shares of common stock to its non-employee independent directors, which vest one year from date of grant so long as the director and/or Company does not terminate their service prior to the vesting date.

19. Subsequent Events

Acquisition

In October 2014, the Company acquired the stock of Allfast Fastening Systems, Inc. ("Allfast") for the cash purchase price of approximately $360 million, at which time it became part of the Company's Aerospace reportable segment. The purchase price remains subject to the finalization of a net working capital adjustment, if any. Located in California, Allfast is a global manufacturer of solid and blind rivets, blind bolts, temporary fasteners and installation tools for the aerospace industry and generated approximately $56 million in revenue for the twelve months ended September 30, 2014.

Debt Financing

In October 2014, the Company amended its Credit Agreement to allow for the borrowing of an incremental $275 million senior secured term loan A facility. The proceeds from the incremental term loan A plus cash and additional borrowings under the Company’s existing senior secured revolving credit facility were used to fund the Allfast acquisition. The incremental term loan A bears interest at borrowing rates consistent with the remainder of the Credit Agreement, amortizes quarterly and matures on October 16, 2018.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition contains forward-looking statements regarding industry outlook and our expectations regarding the performance of our business. These forward-looking statements are subject to numerous risks and uncertainties, including, but not limited to, the risks and uncertainties described under the heading "Forward-Looking Statements," at the beginning of this report. Our actual results may differ materially from those contained in or implied by any forward-looking statements. You should read the following discussion together with the Company's reports on file with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended December 31, 2013.

Introduction

We are a global manufacturer and distributor of products for commercial, industrial and consumer markets. We are principally engaged in six reportable segments: Packaging, Energy, Aerospace, Engineered Components, Cequent APEA and Cequent Americas.

Key Factors and Risks Affecting Our Reported Results.  Our businesses and results of operations depend upon general economic conditions and we serve some customers in cyclical industries that are highly competitive and themselves significantly impacted by changes in economic conditions. Global economic conditions, while remaining a bit choppy, have stabilized over the past 18 to 24 months, albeit with little or no overall economic growth, particularly in the United States. Based on the implementation of our organic and acquisition growth strategies, we have generated higher year-over-year net sales levels in five of our six reportable segments, with the exception being our Energy reportable segment. After strong demand in our Energy reportable segment in the first half of 2013, principally in the United States from engineering and construction customers, demand in the back half of 2013 and into 2014 has significantly declined, both in the United States and abroad, as petrochemical plants and refinery customers continue to defer shutdown activity combined with decreases in engineering and construction and original equipment manufacturers ("OEMs") customer activity. Given the reduced demand and resulting profitability challenges, we announced the closure of a sales branch in China and a manufacturing facility in Brazil during the second quarter of 2014, and may need to evaluate further actions should this negative trend continue.

Over the past few years, we have executed on our growth strategies via bolt-on acquisitions and geographic expansion within our existing platforms in each of our reportable segments. We have also proceeded with footprint consolidation projects within our Cequent reportable segments, moving toward more efficient facilities and lower cost country production. While our growth strategies have significantly contributed to increased net sales levels over this time period, our earnings margins over the period of execution have declined from historical levels, primarily due to the incurrence of duplicate move, acquisition diligence and integration costs, resulting from the acquisition of businesses with historically lower margins than our legacy businesses and due to increasing business in new markets to TriMas, where we make pricing decisions to penetrate new markets and do not yet have volume leverage. In addition to the energy end-market challenges, we have also incurred significant costs related to manufacturing inefficiencies associated with changes in aerospace customer demand, with the trend toward smaller lot sizes and less consistent order patterns over the past few quarters. While these challenges and endeavors have significantly impacted margins, we believe that the margins in these businesses will moderate to historical levels over time (and have in Packaging, for example, where the Innovative Molding and Arminak & Associates acquisitions have been integrated) as we integrate them into our businesses and capitalize on productivity initiatives and volume efficiencies.

Critical factors affecting our ability to succeed include: our ability to create organic growth through product development, cross selling and extending product-line offerings, and our ability to quickly and cost-effectively introduce new products; our ability to acquire and integrate companies or products that supplement existing product lines, add new distribution channels, expand our geographic coverage or enable better absorption of overhead costs; our ability to manage our cost structure more efficiently via supply base management, internal sourcing and/or purchasing of materials, selective outsourcing and/or purchasing of support functions, working capital management, and greater leverage of our administrative functions. If we are unable to do any of the foregoing successfully, our financial condition and results of operations could be materially and adversely impacted.

There is some seasonality in the businesses within our Cequent reportable segments, primarily within Cequent Americas, where sales of towing and trailering products are generally stronger in the second and third quarters, as trailer OEMs, distributors and retailers acquire product for the spring and summer selling seasons. No other reportable segment experiences significant seasonal fluctuation. We do not consider sales order backlog to be a material factor in our business. A growing portion of our sales is derived from international sources, which exposes us to certain risks, including currency risks.

The demand for some of our products, particularly in our two Cequent reportable segments, is heavily influenced by consumer sentiment. Despite the sales increases in the past few years, we recognize that consumer sentiment and the end market conditions remain unstable, primarily for Cequent Americas, given continued uncertainties in employment levels and consumer credit availability, both of which significantly impact consumer discretionary spending.

24

We are sensitive to price movements in our raw materials supply base. Our largest material purchases are for steel, copper, aluminum, polyethylene and other resins and energy. Historically, we have experienced increasing costs of steel and resin and have worked with our suppliers to manage cost pressures and disruptions in supply. We also utilize pricing programs to pass increased steel, copper, aluminum and resin costs to customers. Although we may experience delays in our ability to implement price increases, we have been generally able to recover such increased costs. We may experience disruptions in supply in the future and may not be able to pass along higher costs associated with such disruptions to our customers in the form of price increases.

We report shipping and handling expenses associated with our Cequent Americas reportable segment's distribution network as an element of selling, general and administrative expenses in our consolidated statement of income. As such, gross margins for the Cequent Americas reportable segment may not be comparable to those of our other reportable segments, which primarily rely on third party distributors, for which all costs are included in cost of sales.

Results of Operations

The principal factors impacting us during the three months ended September 30, 2014, compared with the three months ended September 30, 2013, were:

• the impact of our various acquisitions during 2014 and 2013 (see below for the impact by reportable segment);

• business unit restructuring within our Energy reportable segment, under which we incurred approximately $2.1 million of costs during the third quarter of 2014;

• manufacturing and distribution footprint consolidation and relocation projects within our Cequent Americas reportable segment, under which we incurred approximately $0.4 million of costs during the third quarter of 2014, as compared to $4.8 million of such costs during the third quarter of 2013;

• the sale of our business in Italy within the Packaging reportable segment during the third quarter of 2013, for which we recorded a pre-tax gain of approximately $10.5 million;

• our equity offering during the third quarter of 2013, where we issued 5,175,000 shares of common stock for net proceeds of approximately $174.7 million; and

• entry into our new credit agreement ("Credit Agreement") in the fourth quarter of 2013, which allowed us to reduce interest costs.

Overall, net sales increased approximately $25.2 million, or approximately 7.1%, to $380.1 million for the three months ended September 30, 2014, as compared with $354.9 million in the three months ended September 30, 2013. During the third quarter of 2014, net sales increased in all of our reportable segments. Of the sales increase, approximately $19.4 million was due to our recent acquisitions. Sales levels also increased between years due to our expansion in international markets, new customer wins, increased sales to existing customers and the impact of continued strength in certain of our end markets primarily in our Engineered Components and Packaging reportable segments. Sales in our Energy reportable segment increased primarily due to increased demand in North America and increased sales in our international branches. These increases were partially offset by a decrease in sales related to lower demand from our large distribution customers in our Aerospace reportable segment. In addition, net sales decreased due to restructuring activities in our Energy reportable segment and approximately $2.0 million related to the third quarter 2013 sale of our Italian rings and levers business in our Packaging reportable segment. Net sales increased by approximately $1.6 million due to net favorable currency exchange, as our reported results in U.S. dollars were positively impacted as a result of the weaker U.S. dollar relative to foreign currencies.

Gross profit margin (gross profit as a percentage of sales) approximated 25.8% and 26.5% for the three months ended September 30, 2014 and 2013, respectively. Gross profit margin increased in our Engineered Components reportable segment due to increased fixed cost absorption on higher sales levels and due to continued productivity. Gross profit margin also increased due to continued productivity, cost reductions and automation efforts primarily in our Packaging and Cequent Americas reportable segments. Additionally, gross profit margin was favorably impacted in our Cequent Americas reportable segment due to approximately $3.1 million of charges associated with our manufacturing facility footprint consolidation and relocation projects recorded during the three months ended September 30, 2013 that did not repeat in 2014. These increases in gross profit margin were more than offset by increased freight costs in our Cequent Americas reportable segment, less favorable product sales mix primarily in our Packaging, Aerospace, Energy and Cequent APEA reportable segments, increased material costs in our Cequent Americas, Packaging and Engineered Components reportable segments, manufacturing inefficiencies in our Aerospace reportable segment and the impact of restructuring in our Energy reportable segment. In addition, we continued to experience an overall less favorable product sales mix in those reportable segments with recent acquisitions, as the acquired businesses tend to have lower margins than our historical businesses.

Operating profit margin (operating profit as a percentage of sales) approximated 8.5% and 12.3% for the three months ended September 30, 2014 and 2013, respectively. Operating profit decreased approximately $11.3 million, or 26.0%, to $32.3 million for the three months ended September 30, 2014, from $43.6 million for the three months ended September 30, 2013, primarily due to an approximate $10.5 million gain recognized during the third quarter of 2013 within our Packaging reportable segment on the sale of the Italian business, including $7.9 million related to the release of historical currency translation adjustments into net income. Additionally, operating profit margin decreased due to a less favorable product sales mix, primarily in our Packaging, Aerospace, Energy and Cequent APEA reportable segments and as a result of the newly acquired companies comprising a larger percentage of sales and having lower margins than our legacy businesses, manufacturing and labor inefficiencies in our Aerospace

28

reportable segment and the impact of restructuring in our Energy reportable segment. Partially offsetting the decreases in operating profit margin were continued productivity, cost reductions and automation efforts primarily in our Engineered Components, Packaging and Cequent Americas reportable segments as well as operating leverage gained on the higher sales levels primarily in our Engineered Components and Packaging reportable segments. Operating profit margin also increased due to a decrease in costs incurred associated with our manufacturing facility footprint consolidation and relocation projects in our Cequent Americas reportable segment.

Interest expense decreased approximately $2.2 million, to $3.4 million, for the three months ended September 30, 2014, as compared to $5.6 million for the three months ended September 30, 2013. The decrease in interest expense was primarily due to a reduction in our overall interest rates due to the refinancing of our Credit Agreement during the fourth quarter of 2013. The effective weighted average interest rate on our variable rate borrowings, including our Credit Agreement and accounts receivable facilities, decreased to approximately 1.6% for the three months ended September 30, 2014, from 2.7% for the three months ended September 30, 2013. Interest expense further declined due to a decrease in our weighted-average variable rate borrowings to approximately $441.3 million in the three months ended September 30, 2014, from approximately $547.8 million in the three months ended September 30, 2013.

Other income (expense), net increased approximately $4.9 million, to $2.4 million of other expense, net for the three months ended September 30, 2014, compared to $2.5 million of other income, net for the three months ended September 30, 2013. The increase was primarily due to a bargain purchase gain of approximately $2.9 million on the acquisition of certain towing technology and business assets of AL-KO GmbH ("AL-KO") within our Cequent APEA reportable segment during the three months ended September 30, 2013 that did not recur, a reduction of certain indemnification assets related to uncertain tax liabilities during the three months ended September 30, 2014, and higher losses on transactions denominated in foreign currencies.

The effective income tax rates for the three months ended September 30, 2014 and 2013 were 30.7% and 25.3%, respectively. The increase in rates is due to higher earnings in the United States, both in total and as a percentage of total Company, and the absence of tax benefits resulting from the expiration of the American Taxpayer Relief Act of 2012, both of which resulted in an increase in income tax rates during the three months ended September 30, 2014, as compared to the three months ended September 30, 2013.

Net income from continuing operations decreased by approximately $11.9 million, to $18.4 million for the three months ended September 30, 2014, compared to $30.3 million for the three months ended September 30, 2013. The decrease was primarily the result of a $11.3 million decrease in operating profit, plus a $4.9 million increase in other expenses, partially offset by a $2.2 million reduction in interest expense and a $2.1 million decrease in income tax expense.

Net income attributable to noncontrolling interest was $1.3 million for the three months ended September 30, 2013. The income was related to our 70% acquisition of Arminak in February 2012, which represented the 30% interest not attributed to TriMas Corporation. We acquired the remaining 30% interest in Arminak on March 11, 2014. See Note 7, "Arminak & Associates," included in Part 1, Item 1, "Notes to Unaudited Consolidated Financial Statements," within this quarterly report on Form 10-Q.

See below for a discussion of operating results by segment.

Packaging.    Net sales increased approximately $7.3 million, or 8.9%, to $89.3 million in the three months ended September 30, 2014, as compared to $82.0 million in the three months ended September 30, 2013. Sales of our specialty systems products increased by approximately $6.0 million, primarily due to growth from existing customers in the North American and European dispensing markets and continued penetration of the Asian market. Sales further increased $1.7 million resulting from the acquisition of Lion Holdings Pvt. Ltd. ("Lion Holdings") in July of 2014. Sales of our industrial closures decreased by approximately $1.1 million, as improved demand in North America and additional growth from new customers in Europe was more than offset by the loss of approximately $2.0 million in sales from our Italian business which was sold in the third quarter of 2013. In addition, sales increased by approximately $0.7 million due to net favorable currency exchange, as our reported results in U.S. dollars were positively impacted as a result of the weaker U.S. dollar relative to foreign currencies.

Packaging's gross profit increased approximately $0.7 million to $31.2 million, or 34.9% of sales, in the three months ended September 30, 2014, as compared to $30.5 million, or 37.2% of sales, in the three months ended September 30, 2013. Gross profit increased primarily due to the increase in sales. Gross profit margin decreased primarily due to a less favorable product sales mix, as a larger percentage of our sales were generated by specialty dispensing products, increased material costs and as a result of costs incurred related to adding capacity to our two manufacturing facilities in China. These gross profit margin reductions were partially offset by continued productivity and automation initiatives.

29

Packaging's selling, general and administrative expenses increased approximately $0.7 million to $10.3 million, or 11.6% of sales, in the three months ended September 30, 2014, as compared to $9.6 million, or 11.7% of sales, in the three months ended September 30, 2013 primarily due to strategic investments made in order to continue to grow the business, including costs associated with the Lion Holdings acquisition. However, selling, general and administrative expenses remained relatively flat as a percentage of sales due to increased operating leverage gained on the higher sales levels.

Packaging's operating profit decreased approximately $10.5 million to $20.8 million, or 23.3% of sales, in the three months ended September 30, 2014, as compared to $31.3 million, or 38.2% of sales, in the three months ended September 30, 2013. Operating profit and margin decreased primarily due an approximate $10.5 million gain recognized on the sale of the Italian business in the third quarter of 2013, which included approximately $7.9 million related to the release of historical currency translation adjustments into net income. In addition, the less favorable product sales mix and additional costs incurred as we increase our capacity to meet expected demand, primarily in Asia, further reduced operating profit margins, with continued productivity and automation initiatives and additional operating leverage gained on the higher sales levels partially offsetting the decline.

Energy.    Net sales for the three months ended September 30, 2014increased approximately $2.6 million, or 5.5%, to $50.3 million, as compared to $47.7 million in the three months ended September 30, 2013. Sales in North America increased by approximately $2.7 million, as increased demand for standard bolts and gaskets more than offset lower engineering and construction sales. In addition, sales further increased by $1.4 million in our international branches due to continued geographic market expansion and new products. These increases were partially offset by lower sales in China and Brazil as a result of our restructuring activities in those regions in the second quarter of 2014.

Gross profit within Energy increased approximately $0.1 million to $10.3 million, or 20.4% of sales, in the three months ended September 30, 2014, as compared to $10.2 million, or 21.4% of sales, in the three months ended September 30, 2013. While gross profit was essentially flat year-over-year, gross profit margin decreased primarily due to the impact of costs and inefficiencies resulting from the closure of our sales branch in China and restructuring in Brazil, including closing one of our manufacturing facilities, in the second quarter of 2014, additional costs incurred as part of our branch relocation in the United Kingdom and a less favorable product sales mix in North America.

Selling, general and administrative expenses within Energy increased approximately $2.5 million to $11.2 million, or 22.3% of sales, in the three months ended September 30, 2014, as compared to $8.7 million, or 18.3% of sales, in the three months ended September 30, 2013. This increase was primarily related to a $1.9 million reduction in value of certain intangible assets following the restructuring of our business in Brazil, as well as additional selling, general and administrative expenses associated with our recent branch openings and acquisitions.

Overall, operating profit within Energy decreased approximately $2.6 million to a loss of $1.1 million, or 2.2% of sales, in the three months ended September 30, 2014, as compared to $1.5 million of income, or 3.0% of sales, in the three months ended September 30, 2013. Operating profit dollars and margin both decreased as the impact of our two facility closures, branch relocation and higher selling, general and administrative expenses more than offset the profit impact of improved sales in the quarter.

Aerospace.    Net sales for the three months ended September 30, 2014increased approximately $1.6 million, or 6.1%, to $27.4 million, as compared to $25.8 million in the three months ended September 30, 2013. Sales increased approximately $5.4 million related to the acquisition of Mac Fasteners, Inc. ("Mac") in the fourth quarter of 2013. Sales decreased in our legacy aerospace business due to lower demand from our large distribution customers.

Gross profit within Aerospace decreased approximately $2.6 million to $6.7 million, or 24.5% of sales, in the three months ended September 30, 2014, from $9.3 million, or 35.8% of sales, in the three months ended September 30, 2013, primarily due to lower sales levels in our legacy aerospace business. Gross profit margin decreased primarily due to manufacturing and labor inefficiencies resulting from increased change-over and processing related to smaller customer order quantities, less predictable than expected order patterns and a less favorable product sales mix. Additionally, gross profit margin declined due to our Mac acquisition having a lower gross margin than the legacy business.

Selling, general and administrative expenses remained flat at approximately $2.9 million, or 10.4% of sales, in the three months ended September 30, 2014, as compared to $2.9 million, or 11.2% of sales, in the three months ended September 30, 2013, as this segment was able to lower spending levels in the legacy business to offset the incremental normal operating selling, general and administrative costs associated with our Mac acquisition.

Operating profit within Aerospace decreased approximately $2.5 million to $3.9 million, or 14.1% of sales, in the three months ended September 30, 2014, as compared to $6.4 million, or 24.6% of sales, in the three months ended September 30, 2013, as the profit earned on higher sales levels was more than offset by manufacturing and labor inefficiencies, a less favorable product sales mix, and lower profit margins associated with our Mac acquisition.

30

Engineered Components.    Net sales for the three months ended September 30, 2014increased approximately $7.8 million, or 16.3%, to $55.3 million, as compared to $47.5 million in the three months ended September 30, 2013. Sales in our industrial cylinder business increased by approximately $7.3 million, driven primarily by approximately $5.8 million in sales generated from our November 2013 cylinder asset acquisition, as well as increases in our domestic large high pressure cylinders. Sales in our engine business increased by approximately $0.5 million, as increased sales in our gas compression products of approximately $2.2 million resulting from both growth in our existing customer base and new customers was partially offset by decreased sales of our slow speed and compressor engines and related products primarily due to a reduced demand of our single cylinder engines.

Gross profit within Engineered Components increased approximately $4.8 million to $11.7 million, or 21.2% of sales, in the three months ended September 30, 2014, from $6.9 million, or 14.6% of sales, in the three months ended September 30, 2013, primarily as a result of margin improvement in our engine business, as well as higher sales levels in our industrial cylinder business. Gross profit margin in our industrial cylinder business remained flat with the prior year as continued productivity initiatives, increased operating leverage associated with the asset acquisition and other cost reductions were offset by a less favorable product sales mix. Gross profit margin in our engine business increased, as the lower fixed cost absorption we experienced during the third quarter of 2013 that was primarily a result of lower production and procurement levels did not recur in 2014, as well as a favorable product sales mix and continued productivity, which more than offset higher material costs.

Selling, general and administrative expenses decreased approximately $0.4 million to $3.6 million, or 6.5% of sales, in the three months ended September 30, 2014, as compared to $4.0 million, or 8.4% of sales, in the three months ended September 30, 2013, due to lower spending levels, primarily as we incurred diligence costs in 2013 associated with our cylinder asset acquisition, with selling, general and administrative expenses as a percent of sales improving primarily as a result of additional operating leverage.

Operating profit within Engineered Components increased approximately $5.2 million to $8.1 million, or 14.6% of sales, in the three months ended September 30, 2014, as compared to $2.9 million, or 6.0% of sales, in the three months ended September 30, 2013, primarily due to the increased sales levels, with operating profit margin improvement resulting from improved fixed cost absorption in our engine business, continued productivity, operating leverage of the acquired cylinder assets and lower selling, general and administrative costs as a percent of sales.

Cequent APEA.    Net sales increased approximately $3.3 million, or 8.2%, to $44.3 million in the three months ended September 30, 2014, as compared to $41.0 million in the three months ended September 30, 2013. The acquisition of the towing technology and associated assets of AL-KO, in July 2013, contributed approximately $2.9 million of incremental sales. In addition, sales increased due to the positive impact of currency exchange of approximately $0.8 million, as our reported results in U.S. dollars were positively impacted as a result of the weaker U.S. dollar relative to foreign currencies. The increase was partially offset by the loss of an OEM product line produced in Thailand.

Cequent APEA's gross profit increased approximately $0.5 million to $8.8 million, or 19.9% of sales, in the three months ended September 30, 2014, from approximately $8.3 million, or 20.3% of sales, in the three months ended September 30, 2013. Gross profit dollars increased due to the higher sales levels and the impact of approximately $0.5 million of purchase accounting adjustments recorded during the three months ended September 30, 2013 related to the step-up in value and subsequent amortization of inventory in connection with our European acquisitions that did not recur in 2014. Gross profit margin decreased due to a less favorable product and regional sales mix, as the newly acquired European businesses and the growth initiatives in the retail and industrial channels yield lower margins than the legacy business.

Selling, general and administrative expenses increased approximately $0.9 million to $5.6 million, or 12.6% of sales, in the three months ended September 30, 2014, as compared to $4.7 million, or 11.6% of sales, in the three months ended September 30, 2013, primarily in support of our growth initiatives, including approximately $0.9 million of incremental ongoing selling, general and administrative costs related to operating the acquired former AL-KO towing technology assets.

Cequent APEA's operating profit decreased approximately $0.4 million to $3.2 million, or 7.2% of sales, in the three months ended September 30, 2014, as compared to $3.6 million, or 8.7% of net sales, in the three months ended September 30, 2013, as the operating profit dollars generated by the acquisition were more than offset by a less favorable product and regional sales mix and higher selling, general and administrative expenses associated with our growth and geographic expansion efforts.

Cequent Americas.    Net sales increased approximately $2.6 million, or 2.3%, to $113.5 million in the three months ended September 30, 2014, as compared to $110.9 million in the three months ended September 30, 2013, primarily due to year-over-year increases within our aftermarket and retail channels. Net sales within our aftermarket channel increased approximately $2.2 million, primarily due to our November 2013 acquisition of DHF Soluções Automotivas Ltda ("DHF"). Sales within our retail channel increased approximately $0.2 million, primarily due to increased demand from existing customers for towing and towing accessories products and higher sales of our broom and brush product line. Our other market channels remained relatively flat year-over-year.

31

Cequent Americas' gross profit increased approximately $0.5 million to $29.4 million, or 25.9% of sales, in the three months ended September 30, 2014, from approximately $28.9 million, or 26.1% of sales, in the three months ended September 30, 2013, primarily due to higher sales levels, continued productivity projects, including labor savings on the production now moved from our former Goshen, Indiana manufacturing facility to our lower cost country facilities, and vendor cost reductions. In addition, during the three months ended September 30, 2013, we recognized approximately $3.1 million of costs related to the move of production from our Goshen, Indiana manufacturing facility. Although gross profit dollars increased during the three months ended September 30, 2014, gross profit margin decreased primarily due to higher freight costs resulting from our footprint changes and inefficiencies resulting from ramp-up of production in our lower cost country facilities and higher material cost related to increased steel pricing.

Selling, general and administrative expenses decreased approximately $0.8 million to $20.7 million, or 18.2% of sales, in the three months ended September 30, 2014, as compared to $21.5 million, or 19.4% of sales, in the three months ended September 30, 2013, primarily due to approximately $1.2 million of costs incurred during the three months ended September 30, 2013 related to our actions to move and consolidate production facilities as well as lower legal expenses during the third quarter of 2014. Partially offsetting this decrease was higher costs associated with changing our distribution footprint in connection with the Goshen closure and move completion and higher ongoing selling, general and administrative costs associated with our DHF acquisition.

Cequent Americas' operating profit increased approximately $1.3 million to $8.7 million, or 7.6% of sales, in the three months ended September 30, 2014, as compared to $7.4 million, or 6.7% of net sales, in the three months ended September 30, 2013, due to the increase in sales levels, improved productivity and reduced costs resulting from our move of production to our lower cost country facilities and vendor cost reductions.

Corporate Expenses.    Corporate expenses consist of the following:

	Three months ended September 30,
	2014		2013
	(in millions)
Corporate operating expenses	$	5.1	$	3.6
Employee costs and related benefits	6.1		5.8
Corporate expenses	$	11.2	$	9.4

Corporate expenses increased approximately $1.8 million to $11.2 million for the three months ended September 30, 2014, from $9.4 million for the three months ended September 30, 2013. The increase between years is primarily attributed to $1.9 million of acquisition due diligence costs.

Discontinued Operations.    The results of discontinued operations consists of the cessation of operations of the NI Industries business during September 2014. Income from discontinued operations, net of income tax expenses, was $3.8 million for the three months ended September 30, 2014, as compared to a loss from discontinued operations, net of income tax expenses of $0.3 million for the three months ended September 30, 2013. See Note 5, "Discontinued Operations," to our consolidated financial statements included in Part I, Item 1 of this quarterly report on Form 10-Q.

32

Nine Months Ended September 30, 2014 Compared with Nine Months Ended September 30, 2013

Overall, net sales increased approximately $80.1 million, or approximately 7.5%, to $1,148.5 million for the nine months ended September 30, 2014, as compared with $1,068.4 million in the nine months ended September 30, 2013. During the first nine months of 2014, net sales increased in all of our reportable segments except for Energy. Of the sales increase, approximately $71.7 million was due to our recent acquisitions. Sales levels also increased between years due to our expansion in international markets, new customer wins and the impact of continued strength in certain of our end markets primarily in our Packaging, Engineered Components, Cequent Americas and Aerospace reportable segments. These increases were partially offset by a decrease in our Energy reportable segment due primarily to lower engineering and construction sales. In addition, sales decreased by approximately $10.2 million related to the third quarter of 2013 sale of our Italian rings and levers business in our Packaging reportable segment and by approximately $2.3 million due to net unfavorable currency exchange, as our reported results in U.S. dollars were negatively impacted as a result of the stronger U.S. dollar relative to foreign currencies, primarily in our Cequent APEA reportable segment.

Gross profit margin (gross profit as a percentage of sales) approximated 26.4% and 26.2% for the nine months ended September 30, 2014 and 2013, respectively. The gross profit margin in our Cequent Americas reportable segment increased as compared to the first nine months of 2013, due to approximately $9.9 million of charges associated with our manufacturing facility footprint consolidation and relocation projects recorded during the nine months ended September 30, 2013 that did not repeat in 2014. Gross profit margin also increased due to continued productivity, cost reductions and automation efforts primarily in our Engineered Components, Packaging and Cequent Americas reportable segments. The increases in gross profit margin were partially offset by a less favorable product sales mix, primarily in our Energy, Aerospace, Cequent APEA and Packaging reportable segments, increased freight costs in our Cequent Americas reportable segment, manufacturing inefficiencies in our Aerospace reportable segment and the impact of the restructuring in our Energy reportable segment. In addition, we continue to experience an overall less favorable product sales mix in those reportable segments with recent acquisitions, as the acquired businesses tend to have lower margins than our historical businesses.

Operating profit margin (operating profit as a percentage of sales) approximated 9.5% and 10.2% for the nine months ended September 30, 2014 and 2013, respectively. Operating profit decreased approximately $0.2 million, or 0.2%, to $109.0 million for the nine months ended September 30, 2014, compared to $109.2 million for the nine months ended September 30, 2013,primarily due to an approximate $10.5 million gain recognized during the third quarter of 2013 within our Packaging reportable segment on the sale of the Italian business, including $7.9 million related to the release of historical currency translation adjustments into net income. Additionally, operating profit and operating profit margin decreased due to a less favorable product sales mix, primarily in our Energy, Aerospace, Cequent APEA and Packaging reportable segments and as a result of the newly acquired companies comprising a larger percentage of sales and having lower margins than our legacy businesses and manufacturing inefficiencies in our Aerospace reportable segment. Partially offsetting the decreases in operating profit margin were a decrease in costs incurred associated with our manufacturing facility footprint consolidation and relocation projects in our Cequent Americas reportable segment, continued productivity, cost reductions and automation efforts primarily in our Packaging, Engineered Components and Cequent Americas reportable segments as well as operating leverage gained on the higher sales levels primarily in our Packaging and Engineered Components reportable segments.

Interest expense decreased approximately $6.0 million, to $10.3 million, for the nine months ended September 30, 2014, as compared to $16.3 million for the nine months ended September 30, 2013. The decrease in interest expense was primarily due to a reduction in our overall interest rates due to the refinancing of our Credit Agreement during the fourth quarter of 2013. The effective weighted average interest rate on our variable rate borrowings, including our Credit Agreement and accounts receivable facilities, decreased to approximately 1.7% for the nine months ended September 30, 2014, from 2.7% for the nine months ended September 30, 2013. Interest expense further declined due to a decrease in our weighted-average variable rate borrowings to approximately $432.0 million in the nine months ended September 30, 2014, from approximately $545.0 million in the nine months ended September 30, 2013.

Other income (expense), net increased approximately $5.8 million, to $5.2 million of other expense for the nine months ended September 30, 2014, compared to $0.6 million of other income, net for the nine months ended September 30, 2013. The increase was primarily due to a bargain purchase gain of approximately $2.9 million on the acquisition of certain towing technology and business assets of AL-KO within our Cequent APEA reportable segment during the nine months ended September 30, 2013 that did not recur, a reduction of certain indemnification assets related to uncertain tax liabilities during the nine months ended September 30, 2014, and higher losses on transactions denominated in foreign currencies.

The effective income tax rates for the nine months ended September 30, 2014 and 2013 were 31.5% and 23.4%, respectively. The increase in the rate was primarily driven by an increase of earnings in the United States coupled with the absence of tax benefits as a result of the expiration of the American Taxpayer Relief Act of 2012 in the nine months ended September 30, 2014, as compared to the nine months ended September 30, 2013.

33

Net income from continuing operations decreased by approximately $7.4 million, to $64.1 million for the nine months ended September 30, 2014, compared to $71.5 million for the nine months ended September 30, 2013. The decrease was primarily the result of a $7.5 million increase in income tax expense, plus a $5.8 million increase in other expenses, partially offset by a $6.1 million reduction in interest expense.

Net income attributable to noncontrolling interest was $0.8 million for the nine months ended September 30, 2014, compared to $3.1 million for the nine months ended September 30, 2013. The income relates to our 70% acquisition in Arminak in February 2012, which represents the 30% interest not attributed to TriMas Corporation. On March 11, 2014, we acquired the remaining 30% interest in Arminak. See Note 7, "Arminak & Associates," included in Part 1, Item 1, "Notes to Unaudited Consolidated Financial Statements," within this quarterly report on Form 10-Q.

See below for a discussion of operating results by segment.

Packaging.    Net sales increased approximately $22.0 million, or 9.4%, to $257.0 million in the nine months ended September 30, 2014, as compared to $235.0 million in the nine months ended September 30, 2013. Sales of our specialty systems products increased approximately $23.3 million, primarily due to continued increases in demand from our major customers in North America and Europe, as well as continued growth in our revenue base in Asia. Sales further increased $1.7 million resulting from the acquisition of Lion Holdings in the third quarter of 2014. Sales of our industrial closures declined by approximately $5.3 million, primarily as a result of the loss of approximately $10.2 million of sales associated with our Italian rings and levers business sold in the third quarter of 2013, which was partially offset by increased sales of our other industrial closures from 2013 levels, primarily in Europe. In addition, sales increased by approximately $2.3 million due to a net favorable currency exchange, as our reported results in U.S. dollars were positively impacted as a result of the weaker U.S. dollar relative to foreign currencies.

Packaging's gross profit increased approximately $5.7 million to $89.8 million, or 34.9% of sales, in the nine months ended September 30, 2014, as compared to $84.1 million, or 35.8% of sales, in the nine months ended September 30, 2013, primarily due to the higher sales levels. Gross margin decreased slightly from the prior year, as ongoing productivity and automation initiatives and increased sales of our higher-margin European industrial products were more than offset by a less favorable product sales mix, with sales of our lower margin specialty dispensing products comprising a larger percentage of overall sales, as well as costs incurred in Asia as we add capacity to meet expected demand.

Packaging's selling, general and administrative expenses increased approximately $1.0 million to $30.0 million, or 11.7% of sales, in the nine months ended September 30, 2014, as compared to $29.0 million, or 12.3% of sales, in the nine months ended September 30, 2013, as this segment continued to invest in growth initiatives, including costs associated with the Lion Holdings acquisition, while reducing the spending levels as a percentage of net sales due to attaining better operating leverage on the higher sales levels.

Packaging's operating profit decreased approximately $5.9 million to $59.7 million, or 23.2% of sales, in the nine months ended September 30, 2014, as compared to $65.6 million, or 27.9% of sales, in the nine months ended September 30, 2013. Operating profit decreased primarily due an approximate $10.5 million gain recognized on the sale of the Italian business in the third quarter of 2013, which included approximately $7.9 million related to the release of historical currency translation adjustments into net income. In addition to the impact of the Italian business gain in 2013, operating profit margin decreased further as ongoing productivity initiatives and operating leverage gained during the nine months ended September 30, 2014 were more than offset by a less favorable shift in product sales mix.

Energy.    Net sales for the nine months ended September 30, 2014decreased approximately $6.0 million, or 3.7%, to $155.4 million, as compared to $161.4 million in the nine months ended September 30, 2013. Sales increased by approximately $5.3 million due to the recent acquisitions, including Wulfrun Specialised Fasteners ("Wulfrun") and substantially all the business assets of Tat Lee (Thailand) Ltd. ("Tat Lee"). These increases were more than offset by lower sales in North America of approximately $8.9 million, primarily due to lower engineering and construction sales, as the first half of 2013 was a strong period for such sales compared with historical levels, as well as lower demand in certain of the Canadian markets. Also in North America, sales levels increased as a result of increased demand of standard bolts and gaskets, which was mostly offset by the reduction in normal customer shutdown activity at refineries and petrochemical plants. In addition, sales decreased by approximately $2.3 million due to lower sales in China and Brazil as a result of our restructuring activities in those regions in the second quarter of 2014.

Gross profit within Energy decreased approximately $7.7 million to $32.7 million, or 21.0% of sales, in the nine months ended September 30, 2014, as compared to $40.4 million, or 25.0% of sales, in the nine months ended September 30, 2013, primarily due to a less favorable product sales mix, with a higher percentage of sales generated by lower margin standard gaskets and bolts, as well as a higher percentage of sales being generated from our recent acquisitions, which have lower margins than the rest of this business. In addition, gross profit margin was negatively impacted by approximately $1.0 million of costs associated with the closure of our China sales branch and Brazilian manufacturing facility.

34

Selling, general and administrative expenses within Energy increased approximately $3.8 million to $31.7 million, or 20.4% of sales, in the nine months ended September 30, 2014, as compared to $27.9 million, or 17.3% of sales, in the nine months ended September 30, 2013. This increase was primarily related to a $1.9 million reduction in value of certain intangible assets following the restructuring of our business in Brazil, as well approximately $1.4 million for the normal operating selling, general and administrative costs of our recent acquisitions.

Overall, operating profit within Energy decreased approximately $11.7 million to $0.8 million, or 0.6% of sales, in the nine months ended September 30, 2014, as compared to $12.5 million, or 7.8% of sales, in the nine months ended September 30, 2013. Operating profit and profit margin decreased due to a less favorable product sales mix, a higher percentage of our sales being generated by our recent acquisitions, which have lower margins than our historical business, lower sales levels, costs associated with our China branch and Brazil manufacturing facility restructuring and increased selling, general and administrative costs.

Aerospace.    Net sales for the nine months ended September 30, 2014increased approximately $18.2 million, or 26.7%, to $86.4 million, as compared to $68.2 million in the nine months ended September 30, 2013. Sales increased approximately $16.4 million related to the acquisitions of Mac in the fourth quarter of 2013 and Martinic Engineering, Inc. ("Martinic") in the first quarter of 2013. Additionally, we experienced higher sales levels from our new collar product line.

Gross profit within Aerospace increased approximately $0.7 million to $24.9 million, or 28.8% of sales, in the nine months ended September 30, 2014, from $24.2 million, or 35.5% of sales, in the nine months ended September 30, 2013, primarily due to higher sales levels. Gross profit margin decreased primarily due to manufacturing and labor inefficiencies resulting from increased change-over and processing related to smaller customer order quantities, less predictable than expected order patterns associated with our large distribution customers and a less favorable product sales mix. Additionally, gross profit margin declined due to our recent acquisitions having lower gross margins than the legacy aerospace business.

Selling, general and administrative expenses increased approximately $2.1 million to $10.5 million, or 12.2% of sales, in the nine months ended September 30, 2014, as compared to $8.4 million, or 12.3% of sales, in the nine months ended September 30, 2013, primarily due to higher ongoing selling, general and administrative costs of approximately $1.7 million associated with our acquisitions and increased spending in our legacy business in support of our growth initiatives.

Operating profit within Aerospace decreased approximately $1.4 million to $14.4 million, or 16.7% of sales, in the nine months ended September 30, 2014, as compared to $15.8 million, or 23.2% of sales, in the nine months ended September 30, 2013, as manufacturing and labor inefficiencies, a less favorable product sales mix, lower profit margins associated with our recent acquisitions and higher selling, general and administrative expenses in support of our growth initiatives more than offset the impact of higher sales levels.

Engineered Components.    Net sales for the nine months ended September 30, 2014increased approximately $21.3 million, or 14.8%, to $165.1 million, as compared to $143.8 million in the nine months ended September 30, 2013. Sales in our industrial cylinder business increased by approximately $16.0 million, due primarily to approximately $15.0 million in sales being generated from our November 2013 cylinder asset acquisition, as well as continued growth projects related to new products and markets.  Sales in our engine business increased approximately $5.2 million, with an approximate $5.6 million increase related to a large order for compressor packages by a significant customer in the first quarter of 2014. In addition, sales increased in our gas compression products by approximately $3.5 million resulting from both growth in our existing customer base and new customers. These increases were more than offset by an approximately $3.9 million decrease in our slow speed and compressor engine and related products business, primarily due to a reduced demand of our single cylinder engines.

Gross profit within Engineered Components increased approximately $10.7 million to $35.7 million, or 21.6% of sales, in the nine months ended September 30, 2014, from $25.0 million, or 17.3% of sales, in the nine months ended September 30, 2013, primarily due to margin improvement, as well as higher sales levels in both of our businesses. Gross profit margin in our industrial cylinder business increased due to continued productivity initiatives and operating leverage gained on the recent cylinder asset acquisition, which was partially offset by a less favorable product sales mix. Gross profit margin in our engine business increased, as the lower fixed cost absorption we experienced during the third quarter of 2013, that was primarily a result of lower production and procurement levels, did not recur in 2014, and as a result of a more favorable product sales mix and continued productivity.

Selling, general and administrative expenses increased approximately $0.2 million to $10.6 million, or 6.4% of sales, in the nine months ended September 30, 2014, as compared to $10.4 million, or 7.3% of sales, in the nine months ended September 30, 2013, as spending levels were held relatively consistent compared to the prior year, with selling, general and administrative expenses as a percent of sales improving primarily as a result of additional operating leverage.

35

Operating profit within Engineered Components increased approximately $10.4 million to $24.9 million, or 15.1% of sales, in the nine months ended September 30, 2014, as compared to operating profit of $14.5 million, or 10.0% of sales, in the nine months ended September 30, 2013, primarily due to the increased sales levels, with margin improvement resulting from improved fixed cost absorption in our engine business, continued productivity and cost reduction initiatives and the operating leverage gained on selling, general and administrative expenses.

Cequent APEA.    Net sales increased approximately $16.3 million, or 14.6%, to $127.6 million in the nine months ended September 30, 2014, as compared to $111.3 million in the nine months ended September 30, 2013. The acquisitions of C.P. Witter Limited ("Witter"), in April 2013, and the towing technology and associated assets of AL-KO, in July 2013, contributed approximately $23.2 million of incremental sales. The increase was partially offset by lower sales related to general economic conditions in Australia resulting in reduced consumer and business confidence, the loss of an OEM product line produced in Thailand and the negative impact of currency exchange of approximately $3.7 million, as our reported results in U.S. dollars were negatively impacted as a result of the stronger U.S. dollar relative to foreign currencies.

Cequent APEA's gross profit increased approximately $1.8 million to $25.0 million, or 19.6% of sales, in the nine months ended September 30, 2014, from approximately $23.2 million, or 20.8% of sales, in the nine months ended September 30, 2013. Gross profit dollars increased due to the higher sales levels and the impact of approximately $1.2 million of purchase accounting-related adjustments recorded during the nine months ended September 30, 2013 related to the step-up in value and subsequent amortization of inventory in connection with our European acquisitions that did not recur. Gross profit margin decreased due to a less favorable product and regional sales mix, as the newly acquired European businesses and the growth initiatives in the retail and industrial channels yield lower margins than the legacy business.

Selling, general and administrative expenses increased approximately $3.2 million to $17.1 million, or 13.4% of sales, in the nine months ended September 30, 2014, as compared to $13.9 million, or 12.5% of sales, in the nine months ended September 30, 2013, primarily in support of our growth initiatives, including approximately $2.6 million of incremental ongoing selling, general and administrative costs related to the acquired European businesses.

Cequent APEA's operating profit decreased approximately $1.4 million to approximately $7.9 million, or 6.2% of sales, in the nine months ended September 30, 2014, as compared to $9.3 million, or 8.4% of net sales, in the nine months ended September 30, 2013, as the higher operating profit generated by the acquisitions, net of the ongoing selling, general and administrative costs related thereto, was more than offset by the impact of lower sales levels in Australia due to economic uncertainties and their impact on reducing consumer spending levels.

Cequent Americas.    Net sales increased approximately $8.5 million, or 2.4%, to $357.1 million in the nine months ended September 30, 2014, as compared to $348.6 million in the nine months ended September 30, 2013, primarily due to year-over-year increases within our aftermarket and retail channels. While our Brazilian operations generated approximately $6.2 million of incremental net sales during the nine months ended September 30, 2014, adding to our aftermarket channel sales, the remainder of the aftermarket channel declined approximately $0.4 million as compared to the nine months ended September 30, 2013. Sales within our retail channel increased approximately $2.7 million, primarily due to increased demand from existing customers for towing, towing accessories and cargo management products and higher sales of our broom and brush product line. Our other market channels remained relatively flat year-over-year.

Cequent Americas' gross profit increased approximately $12.0 million to $95.4 million, or 26.7% of sales, in the nine months ended September 30, 2014, as compared to $83.4 million, or 23.9% of sales, in the nine months ended September 30, 2013, primarily due to approximately $9.9 million of costs incurred during the nine months ended September 30, 2013 associated with the closure of our Goshen, Indiana manufacturing facility and the relocation of the production therefrom to our lower cost country facilities that did not recur in 2014. Additionally, gross profit margin increased due to continued productivity projects, including labor savings on the production now moved from Goshen to our lower cost country facilities, vendor cost reductions and higher margins from our broom and brush product line as compared to the nine months ended September 30, 2013. The increases in gross profit dollars and margin were partially offset by approximately $1.8 million of costs recognized during the nine months ended September 30, 2014, primarily related to higher freight costs due to split shipments resulting from our footprint changes and inefficiencies resulting from ramp-up of production in our lower cost country facilities.

Selling, general and administrative expenses increased approximately $1.6 million to $64.0 million, or 17.9% of sales, in the nine months ended September 30, 2014, as compared to $62.4 million, or 17.9% of sales, in the nine months ended September 30, 2013, primarily as a result of higher ongoing selling, general and administrative costs associated with our recent acquisition, higher costs associated with changing our distribution footprint in connection with the Goshen closure and move completion, higher employee costs associated with growth initiatives and an increase in sales. The increase was partially offset by approximately $2.1 million of costs incurred during the nine months ended September 30, 2013 related to our actions to move and consolidate production facilities.

36

Cequent Americas' operating profit increased approximately $10.3 million to $31.3 million, or 8.8% of sales, in the nine months ended September 30, 2014, as compared to $21.0 million, or 6.0% of net sales, in the nine months ended September 30, 2013, due to higher sales levels, costs incurred during the first half of 2013 in connection with the footprint and lower cost country project that did not recur, productivity projects, including labor savings in our lower cost country facilities and vendor cost reductions.

Corporate Expenses.    Corporate expenses consist of the following:

	Nine months ended September 30,
	2014		2013
	(in millions)
Corporate operating expenses	$	12.2	$	11.8
Employee costs and related benefits	17.9		17.7
Corporate expenses	$	30.1	$	29.5

Corporate expenses increased approximately $0.6 million to $30.1 million for the nine months ended September 30, 2014, from $29.5 million for the nine months ended September 30, 2013. The increase between years is primarily attributed to $1.9 million related to acquisition due diligence costs, which was partially offset by a decrease in costs associated with third party professional fees.

Discontinued Operations.     The results of discontinued operations consists of the cessation of operations of the NI Industries business during September 2014, and our precision tool cutting and specialty fitting lines of business, which were sold in December 2011. Income from discontinued operations, net of income tax expenses, was $3.8 million for the the nine months ended September 30, 2014, as compared to $0.3 million for the nine months ended September 30, 2013. See Note 5, "Discontinued Operations," to our consolidated financial statements included in Part I, Item 1 of this quarterly report on Form 10-Q.

Liquidity and Capital Resources

Cash Flows

Cash flows provided by operating activities were approximately $64.9 million and $41.3 million for the nine months ended September 30, 2014 and 2013, respectively. Significant changes in cash flows provided by operating activities and the reasons for such changes are as follows:

• For the nine months ended September 30, 2014, the Company generated $102.2 million of cash, based on the reported net income of $67.8 million and after considering the effects of non-cash items related to gains on disposition of assets, bargain purchase gain, depreciation, amortization, stock-based compensation and related changes in excess tax benefits, changes in deferred income taxes, and other, net. For the nine months ended September 30, 2013, the Company generated $99.4 million in cash flows based on the reported net income of $71.8 million and after considering the effects of similar non-cash items.

• Increases in accounts receivable resulted in a use of cash of approximately $43.5 million and $48.6 million for the nine months ended September 30, 2014 and 2013, respectively. The increase in accounts receivable is due primarily to the increase in sales between the comparable periods, as the third quarter is a higher historical sales quarter than the fourth quarter, and the timing of sales and collection of cash within the period. Our days sales outstanding of receivables remained relatively flat period-over-period.

• Decreases in inventory resulted in a cash source of approximately $7.4 million and $1.8 million for the nine months ended September 30, 2014 and 2013, respectively. During the first nine months of 2014, our gross inventory levels decreased as compared to year end, primarily due to the seasonality in our Cequent Americas reportable segment. In addition, inventory levels in our Cequent Americas reportable segment declined as the safety stock levels built in preparation for the move from our Goshen, Indiana manufacturing facility to lower cost country facilities were consumed and replenished at lower levels.

• Decreases in prepaid expenses and other assets resulted in a cash source of approximately $2.3 million for the nine months ended September 30, 2014. The decrease in prepaid expenses and other assets is primarily due to the reduction of certain indemnification assets related to uncertain tax liabilities. Increases in prepaid expenses and other assets resulted in a use of cash of approximately $7.1 million for the nine months ended September 30, 2013. The increase for the nine months ended September 30, 2013 related primarily to prepaid foreign taxes of $3.6 million. The remaining increase was due primarily to additional investments in manufacturing supplies, spare parts and tooling assets, as well as prepaid advertising costs, to support our increased sales levels.

• Decreases in accounts payable and accrued liabilities resulted in a use of cash of approximately $3.5 million and $4.3 million for the nine months ended September 30, 2014 and 2013, respectively. The change in cash used for accounts payable and accrued liabilities is primarily a result of the timing of payments made to suppliers and mix of vendors and related terms. Days of accounts payable on hand remained relatively flat period-over-period.

Net cash used for investing activities for the nine months ended September 30, 2014 and 2013 was approximately $48.3 million and $80.4 million, respectively. During the first nine months of 2014, we incurred approximately $27.8 million in capital expenditures, as we have continued our investment in growth, capacity and productivity-related capital projects. In addition, we paid approximately $27.5 million for the acquisition of Lion Holdings, and received cash from the disposition of assets of approximately $7.0 million that was primarily related to the sale of certain intellectual property and related inventory and tooling within our discontinued NI Industries business. During the first nine months of 2013, we paid approximately $56.0 million for business acquisitions, including the acquisition of Martinic in our Aerospace reportable segment, Wulfrun in our Energy reportable segment and Witter and the towing assets of AL-KO in our Cequent APEA reportable segment. During the first nine months of 2013, we invested approximately $35.2 million in capital expenditures. Cash received from the disposition of assets was approximately $10.7 million for the first nine months of 2013, primarily related to the sale of our business in Italy within our Packaging reportable segment.

Net cash used for financing activities was approximately $13.5 million for the nine months ended September 30, 2014, and net cash provided by financing activities was approximately $227.9 million for the nine months ended September 30, 2013. During the first nine months of 2014, we purchased the remaining 30% noncontrolling interest of Arminak for a cash purchase price of $51.0 million. In addition, during the nine months ended September 30, 2014, we had net additional borrowings of approximately $45.0 million on our receivables and revolving credit facilities and net additional repayments of approximately $5.7 million on our term loan facilities. We also used a net cash amount of approximately $1.2 million related to our stock compensation arrangements. During the third quarter of 2013, we completed an equity offering which resulted in net proceeds of approximately $174.7 million. During the nine months ended September 30, 2013, we had net additional borrowings of approximately $57.0

38

million on our receivables and revolving credit facilities and net additional repayments of approximately $1.6 million on our term loan facilities. In addition, we used a net cash amount of approximately $1.3 million related to our stock compensation arrangements and $1.9 million in distributions to noncontrolling interests.

Our Debt and Other Commitments

We are party to a credit agreement consisting of a $575.0 million senior secured revolving credit facility, which matures in October 2018 and is subject to interest at London Interbank Offered Rates ("LIBOR") plus 1.50% and a $175.0 million senior secured term loan A facility, which matures in October 2018 and is subject to interest at LIBOR plus 1.50% (collectively, the "Credit Agreement"). The interest rate spread is based upon the leverage ratio, as defined, as of the most recent determination date. Per the Credit Agreement, the senior secured revolving credit facility permits borrowings denominated in specific foreign currency ("Foreign Currency Loans"), subject to a $75.0 million sub limit.

At September 30, 2014, $168.4 million was outstanding on the term loan A facility and $103.0 million was outstanding on the revolving credit facility. The Credit Agreement allows issuance of letters of credit, not to exceed $75.0 million in aggregate, against revolving credit facility commitments.

The Credit Agreement also provides for incremental term loan facility and/or revolving credit commitments, not to exceed the greater of $300.0 million and an amount such that, after giving effect to the making of such commitments and the incurrence of any other indebtedness substantially simultaneously with the making of such commitments, the senior secured net leverage ratio, as defined, is no greater than 2.50 to 1.00, as defined. The terms and conditions of any incremental term loan and/or revolving credit facility commitments must be no more favorable than the existing credit facility. Under the Credit Agreement, beginning with the fiscal year ended December 31, 2014 (payable in 2015), we may be required to prepay a portion of our term loan A facility in an amount equal to a percentage of our excess cash flow, as defined, which such percentage will be based on our leverage ratio, as defined.

Amounts drawn under our revolving credit facility fluctuate daily based upon our working capital and other ordinary course needs. Availability under our revolving credit facility depends upon, among other things, compliance with our Credit Agreement's financial covenants. Our Credit Agreement contains various negative and affirmative covenants and other requirements affecting us and our subsidiaries, including restrictions on incurrence of debt, liens, mergers, investments, loans, advances, guarantee obligations, acquisitions, asset dispositions, sale-leaseback transactions, hedging agreements, dividends and other restricted payments, transactions with affiliates, restrictive agreements and amendments to charters, bylaws, and other material documents. The terms of our Credit Agreement require us and our subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a maximum leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined) and a minimum interest expense coverage ratio (consolidated EBITDA, as defined, over cash interest expense, as defined). Our permitted leverage ratio under the Credit Agreement is 3.50 to 1.00 as of September 30, 2014. If we were to complete an acquisition which qualifies for a Covenant Holiday Period, as defined in our Credit Agreement, then our permitted leverage ratio cannot exceed 4.00 to 1.00 during that period. Our actual leverage ratio was 1.74 to 1.00 at September 30, 2014. Our permitted interest expense coverage ratio under the Credit Agreement is 3.00 to 1.00 as of September 30, 2014. Our actual interest expense coverage ratio was 18.51 to 1.00 at September 30, 2014. At September 30, 2014, we were in compliance with our financial and other covenants.

In addition, this Dutch subsidiary is subject to an overdraft facility in conjunction with the uncommitted working capital facility up to $1.0 million, subject to interest at U.S. Dollar Prime Rate ("Prime Rate") plus 0.75%. No amounts were outstanding on this facility as of September 30, 2014.

Another important source of liquidity is our $105.0 million accounts receivable facility, under which we have the ability to sell eligible accounts receivable to a third-party multi-seller receivables funding company. We amended the facility in April 2014, reducing the usage fee on amounts outstanding previously ranging from 1.20% or 1.35%, depending on the amounts drawn under the facility, to 1.15%. The amendment also reduced the cost of the unused portion of the facility from 0.40% to 0.35% and extended the maturity date from October 12, 2017 to October 16, 2018. We had $66.3 million and $57.0 million outstanding under the facility as of September 30, 2014 and December 31, 2013 and $27.1 million and $20.2 million, respectively, available but not utilized.

At September 30, 2014, we had $103.0 million outstanding under our revolving credit facility and had $452.1 million potentially available after giving effect to approximately $21.9 million of letters of credit issued and outstanding. At December 31, 2013, we had$71.1 millionoutstanding under our revolving credit facility and had$479.8 million potentially available after giving effect to approximately $24.1 million of letters of credit issued and outstanding. The letters of credit are used for a variety of purposes, including support of certain operating lease agreements, vendor payment terms and other subsidiary operating activities, and to meet various states' requirements to self-insure workers' compensation claims, including incurred but not reported claims. Including availability under our accounts receivable facility and after consideration of leverage restrictions contained in the Credit Agreement, as of September 30, 2014 and December 31, 2013, we had $366.7 million and $360.3 million, respectively, of borrowing capacity available for general corporate purposes.

Before consideration of our financial covenants, our available revolving credit capacity under the Credit Agreement, after consideration of approximately $21.9 million in letters of credit outstanding related thereto, is approximately $452.1 million, while our available liquidity under our accounts receivable facility ranged from $66 million to $96 million for the last 12 months, depending on the level of our receivables outstanding at a given point in time during the year. We rely upon our cash flow from operations and available liquidity under our revolving credit and accounts receivable facilities to fund our debt service obligations and other contractual commitments, working capital and capital expenditure requirements. At the end of each quarter, we use

41

cash on hand from our domestic and foreign subsidiaries to pay down amounts outstanding under our revolving credit and accounts receivable facilities. Generally, excluding the impact and timing of acquisitions, we use available liquidity under these facilities to fund capital expenditures and daily working capital requirements during the first half of the year, as we experience some seasonality in our two Cequent reportable segments, primarily within Cequent Americas. Sales of towing and trailering products within this segment are generally stronger in the second and third quarters, as OEM, distributors and retailers acquire product for the spring and summer selling seasons. None of our other reportable segments experience any significant seasonal fluctuations in their respective businesses. During the second half of the year, the investment in working capital is reduced and amounts outstanding under our revolving credit and receivable facilities are paid down.

Our combined weighted average monthly amounts outstanding on our Credit Agreement and our accounts receivable facility during the first nine months of 2014 approximated $432.0 million, compared to the weighted average daily amounts outstanding during the first nine months of 2013 of $545.0 million. The overall reduction is due primarily to proceeds from the equity offering during the third quarter of 2013 and the additional operating cash flow generated during the first nine months of 2014 compared to the same period in 2013, as the cash use related to the purchase of noncontrolling interest and acquisitions during the first nine months of 2014 was greater than the cash use for acquisitions during the first nine months of 2013.

Cash management related to our revolving credit and accounts receivable facilities is centralized. We monitor our cash position and available liquidity on a daily basis and forecast our cash needs on a weekly basis within the current quarter and on a monthly basis outside the current quarter over the remainder of the year. Our business and related cash forecasts are updated monthly. Given aggregate available funding under our revolving credit and accounts receivable facilities of $366.7 million at September 30, 2014, after consideration of the aforementioned leverage restrictions, and based on forecasted cash sources and requirements inherent in our business plans, we believe that our liquidity and capital resources, including anticipated cash flows from operations, will be sufficient to meet our debt service, capital expenditure and other short-term and long-term obligation needs for the foreseeable future.

Our exposure to interest rate risk results from the variable rates under our Credit Agreement. Borrowings under the Credit Agreement bear interest, at various rates, as more fully described in Note 11, "Long-term Debt," to our consolidated financial statements included in Part I, Item 1 of this quarterly report on Form 10-Q. In December 2012, we entered into an interest rate swap agreement to fix the LIBOR-based variable portion of the interest rates on our term loan facility. The term loan A swap agreement fixes the LIBOR-based variable portion of the interest rate, on a total of $175.0 million notional amount at 0.74% and expires on October 11, 2017.

We are subject to variable interest rates on our term loan and revolving credit facility. At September 30, 2014, 1-Month LIBOR and 3-Month LIBOR approximated 0.15% and 0.24%, respectively. Based on our variable rate-based borrowings outstanding at September 30, 2014, and after consideration of the interest rate swap agreement associated with our term loan A, a 1% increase in the per annum interest rate would increase our interest expense by approximately $1.8 million annually.

Principal payments required under the Credit Agreement for the term loan A facility are $2.2 million due each calendar quarter beginning March 2014 through December 2016 and approximately $3.3 million from March 2017 through September 2018, with final payment of $125.8 million due on October 16, 2018.

In addition to our long-term debt, we have other cash commitments related to leases. We account for these lease transactions as operating leases and annual rent expense for continuing operations related thereto approximated $29.4 million. We expect to continue to utilize leasing as a financing strategy in the future to meet capital expenditure needs and to reduce debt levels.

In October 2014, we acquired the stock of Allfast Fastening Systems, Inc. ("Allfast") for the cash purchase price of approximately $360 million, at which time it became part of our Aerospace reportable segment. See Note 19, "Subsequent Events," included in Part 1, Item 1, "Notes to Unaudited Consolidated Financial Statements," within this quarterly report on Form 10-Q. Also, in October 2014, we amended our Credit Agreement to allow for the borrowing of an incremental $275 million senior secured term loan A facility. The proceeds from the incremental term loan A plus cash and additional borrowings under our existing senior secured revolving credit facility were used to fund the Allfast acquisition. The incremental term loan A bears interest at rates consistent with the remainder of the Credit Agreement, which may vary based on our leverage ratio, amortizes quarterly and matures on October 16, 2018.

Market Risk

We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies. The functional currencies of our foreign subsidiaries are primarily the local currency in the country of domicile. We manage these operating activities at the local level and revenues and costs are generally denominated in local currencies; however, results of operations and assets and liabilities reported in U.S. dollars will fluctuate with changes in exchange rates between such local currencies and the U.S. dollar.

42

We use derivative financial instruments to manage currency risks associated with our procurement activities denominated in currencies other than the functional currency of our subsidiaries and the impact of currency rate volatility on our earnings. As of September 30, 2014, we were party to forward contracts to hedge changes in foreign currency exchange rates with notional amounts of approximately $11.0 million.

We are also subject to interest risk as it relates to our long-term debt. We have historically and continue to use interest rate swap agreements to fix the variable portion of our debt to manage this risk. See Note 12, "Derivative Instruments," included in Part 1, Item 1, "Notes to Unaudited Consolidated Financial Statements," within this quarterly report on Form 10-Q.

Common Stock

TriMas is listed in the NASDAQ Global Select Market^SM. Our stock trades under the symbol "TRS".

Credit Rating

We and certain of our outstanding debt obligations are rated by Standard & Poor's and Moody's. On September 30, 2014, Moody's affirmed a rating of Ba2 to our senior secured credit facilities, as presented in Note 11, "Long-term Debt" included in Item 1, "Consolidated Financial Statements" within this Form 10-Q. Moody's also affirmed a Ba2 to our Corporate Family Rating and maintained our outlook as stable. On October 8, 2014, Standard & Poor's assigned a BB- corporate credit rating to our new $275 million incremental term loan A facility used to fund the Allfast acquisition. Standard & Poor's also affirmed a BB- rating to our senior secured credit facilities and maintained our outlook as stable. If our credit ratings were to decline, our ability to access certain financial markets may become limited, our cost of borrowings may increase, the perception of us in the view of our customers, suppliers and security holders may worsen and as a result, we may be adversely affected.

Outlook

We continue to expect demand in the remainder of 2014 to be uncertain and volatile in the end markets we serve, exhibiting limited economic growth, with the primary challenges being the energy, aerospace and Australia end markets. In our energy business, the first half of 2013 yielded record profit levels, but results in the subsequent quarters have been lower than historical levels, with a higher percentage of standard product than highly-engineered product sales, and the overall demand has not yet fully recovered. We announced the closure of two facilities in 2014, and continue to evaluate further restructuring opportunities in this business in response to the lower than historical revenue and profit levels. In our aerospace business, we have experienced challenges with smaller lot-size orders from our customers and optimizing our manufacturing of product associated with min/max programs, both of which have lowered our throughput and required additional setups and shorter part runs. In Australia, we have entered the selling-season in the third quarter with lower than expected demand levels given lower than historical discretionary spending levels in that region.

In addition to the end-market challenges, while the move of our largest manufacturing facility in the Cequent Americas reportable segment is complete, we continue to experience inefficiencies in our manufacturing and supply chain processes and input cost challenges related to localization of steel supply and elevated freight and logistics costs. We have devoted significant resources to mitigating these challenges and expect to improve profit levels as the solutions are implemented.

We also expect to devote considerable effort into fully-integrating our 12 acquisitions completed during 2013 and 2014 into our businesses and gaining the expected synergies.

While these end-market challenges and acquisition of companies with lower margins than our legacy businesses may continue to put further short-term pressure on profit margins, we believe margins in these businesses will moderate to historical TriMas levels over time as we integrate acquisitions, implement our productivity and automation initiatives and consider restructuring of our businesses to lower costs and increase efficiencies given the current economic environment.

Our priorities remain consistent with our strategic aspirations: enhancing margins via cost savings and productivity initiatives that fund core growth, reducing cycle times and securing our position as best cost producer, growing revenue via new products, global expansion and acquisitions and continuing to optimize our capital structure.

Impact of New Accounting Standards

See Note 2, "New Accounting Pronouncements," included in Part 1, Item 1, "Notes to Unaudited Consolidated Financial Statements," within this quarterly report on Form 10-Q.

43

Critical Accounting Policies

Certain of our accounting policies require the application of significant judgment by management in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, our evaluation of business and macroeconomic trends, and information from other outside sources, as appropriate.

During the quarter ended September 30, 2014, there were no material changes to the items that we disclosed as our critical accounting policies in Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations," in the Annual Report on Form 10-K for the year ended December 31, 2013.

44

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

In the normal course of business, we are exposed to market risk associated with fluctuations in foreign currency exchange rates. We are also subject to interest risk as it relates to long-term debt. See Part I, Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations," for details about our primary market risks, and the objectives and strategies used to manage these risks. Also see Note 11, "Long-term Debt," and Note 12, "Derivative Instruments," in Part I, Item 1, "Notes to Unaudited Consolidated Financial Statements," included within this quarterly report on Form 10-Q for additional information.

Item 4.    Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that the Company files or submits under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Evaluation of disclosure controls and procedures

As of September 30, 2014, an evaluation was carried out by management, with the participation of the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and Rule 15d-15(e) of the Exchange Act) pursuant to Rule 13a-15 of the Exchange Act. The Company's disclosure controls and procedures are designed only to provide reasonable assurance that they will meet their objectives. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of September 30, 2014, the Company's disclosure controls and procedures are effective to provide reasonable assurance that they would meet their objectives.

Changes in internal control over financial reporting

There have been no changes in the Company's internal control over financial reporting during the quarter ended September 30, 2014 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Acquisition

In October 2014, the Company acquired the stock of Allfast Fastening Systems, Inc. ("Allfast") for the cash purchase price of approximately $360 million, at which time it became part of the Company's Aerospace reportable segment. The purchase price remains subject to the finalization of a net working capital adjustment, if any. Located in California, Allfast is a global manufacturer of solid and blind rivets, blind bolts, temporary fasteners and installation tools for the aerospace industry and generated approximately $56 million in revenue for the twelve months ended September 30, 2014.

Debt Financing

In October 2014, the Company amended its Credit Agreement to allow for the borrowing of an incremental $275 million senior secured term loan A facility. The proceeds from the incremental term loan A plus cash and additional borrowings under the Company’s existing senior secured revolving credit facility were used to fund the Allfast acquisition. The incremental term loan A bears interest at borrowing rates consistent with the remainder of the Credit Agreement, amortizes quarterly and matures on October 16, 2018.

Asbestos

As of September 30, 2014, the Company was a party to 1,105 pending cases involving an aggregate of 8,001 claimants alleging personal injury from exposure to asbestos containing materials formerly used in gaskets (both encapsulated and otherwise) manufactured or distributed by certain of the Company's subsidiaries for use primarily in the petrochemical refining and exploration industries. The following chart summarizes the number of claimants, number of claims filed, number of claims dismissed, number of claims settled, the average settlement amount per claim and the total defense costs, exclusive of amounts reimbursed under the Company's primary insurance, at the applicable date and for the applicable periods:

	Claims pending at beginning of period	Claims filed during period	Claims dismissed during period	Claims settled during period	Average settlement amount per claim during period		Total defense costs during period
Fiscal Year Ended December 31, 2013	7,880	360	226	39	$	8,294	$	2,620,000
Nine Months Ended September 30, 2014	7,975	151	103	22	$	8,973	$	1,987,000

In addition, the Company acquired various companies to distribute its products that had distributed gaskets of other manufacturers prior to acquisition. The Company believes that many of its pending cases relate to locations at which none of its gaskets were distributed or used.

The Company may be subjected to significant additional asbestos-related claims in the future, the cost of settling cases in which product identification can be made may increase, and the Company may be subjected to further claims in respect of the former activities of its acquired gasket distributors. The Company is unable to make a meaningful statement concerning the monetary claims made in the asbestos cases given that, among other things, claims may be initially made in some jurisdictions without specifying the amount sought or by simply stating the requisite or maximum permissible monetary relief, and may be amended to alter the amount sought. The large majority of claims do not specify the amount sought. Of the 8,001 claims pending at September 30, 2014, 102 set forth specific amounts of damages (other than those stating the statutory minimum or maximum). Below is a breakdown of the amount sought for those claims seeking specific amounts:

	Compensatory & Punitive			Compensatory Only			Punitive Only
Range of damages sought (in millions)	$0.0 to $5.0	$5.0 to $10.0	$10.0+	$0.0 to $0.6	$0.6 to $5.0	$5.0+	$0.0 to $2.5	$2.5 to $5.0	$5.0+
Number of claims	76	13	13	26	57	19	94	7	1

In addition, relatively few of the claims have reached the discovery stage and even fewer claims have gone past the discovery stage.

Total settlement costs (exclusive of defense costs) for all asbestos-related cases, some of which were filed over 20 years ago, have been approximately $6.8 million. All relief sought in the asbestos cases is monetary in nature. To date, approximately 40% of the Company's costs related to settlement and defense of asbestos litigation have been covered by its primary insurance. Effective February 14, 2006, the Company entered into a coverage-in-place agreement with its first level excess carriers regarding the coverage to be provided to the Company for asbestos-related claims when the primary insurance is exhausted. The coverage-in-place agreement makes asbestos defense costs and indemnity coverage available to the Company that might otherwise be disputed by the carriers and provides a methodology for the administration of such expenses. Nonetheless, the Company believes it is likely there will be a period within the next one or two years, prior to the commencement of coverage under this agreement and following exhaustion of the Company's primary insurance coverage, during which the Company will be solely responsible for defense costs and indemnity payments, the duration of which would be subject to the scope of damage awards and settlements paid.

Based on the settlements made to date and the number of claims dismissed or withdrawn for lack of product identification, the Company believes that the relief sought (when specified) does not bear a reasonable relationship to its potential liability. Based upon the Company's experience to date, including the trend in annual defense and settlement costs incurred to date, and other available information (including the availability of excess insurance), the Company does not believe these cases will have a material adverse effect on its financial position and results of operations or cash flows.

Ordinary Course Claims

The Company is subject to other claims and litigation in the ordinary course of business, but does not believe that any such claim or litigation will have a material adverse effect on its financial position and results of operations or cash flows.

The Company did not incur significant stock-based compensation expense related to stock options during the nine months ended September 30, 2014 and 2013.

Restricted Shares

The Company awarded 600 restricted stock grants to certain employees during the third quarter of 2014. These shares are subject only to a service condition and vest on the first anniversary date of the award so long as the employee remains with the Company.

During the nine months ended September 30, 2014, the Company issued 7,409 shares related to director fee deferrals. The Company allows for its non-employee independent directors to make an annual election to defer all or a portion of their directors fees and to receive the deferred amount in cash or equity. Certain of the Company's directors have elected to defer all or a portion of their directors fees and to receive the amount in Company common stock at a future date.

The Company also awarded multiple restricted stock grants during the first quarter of 2014. First, the Company granted 23,226 restricted shares of common stock to certain employees which are subject only to a service condition and vest ratably over three years so long as the employee remains with the Company.

The Company awarded 40,837 restricted shares of common stock to certain employees during thefirst quarter of 2014. These shares are subject only to a service condition and vest on the first anniversary date of the award. The awards were made to participants in the Company's short-term incentive compensation plan ("STI"), where all STI participants whose target annual award exceeds $20 thousand receive 80% of the value in earned cash and 20% in the form of a restricted stock award upon finalization of the award amount in the first quarter each year following the previous plan year.

The Company awarded243,124 restricted shares of common stock to certain Company key employees during thefirst quarter of 2014. Half of the restricted shares granted are service-based restricted stock units. These awards vest ratably over three years. The other half of the shares are subject to a performance condition and are earned based upon the achievement of two performance metrics over a period of three calendar years, beginning on January 1, 2014 and ending on December 31, 2016. Of this award, 75% of the awards are earned based upon the Company's earnings per share ("EPS") cumulative average growth rate ("EPS CAGR") over the performance period. The remaining 25% of the grants are earned based upon the Company's three-year average return on invested capital ("ROIC"). ROIC is defined as the Company's after-tax operating profit, as publicly reported by the Company, plus or minus special items that may occur from time-to-time, divided by the Company's last five-quarter average of invested capital. Invested capital is comprised of the Company's long-term debt plus shareholders' equity plus non-controlling interest, less cash held. Depending on the performance achieved for these two metrics, the amount of shares earned can vary from 30% of the target award to a maximum amount of 200% of the target award for the ROIC metric and 250% of the target award for the EPS CAGR metric. However, if these performance metrics are not achieved, no award will be earned. The performance awards vest on a "cliff" basis at the end of the three-year performance period.

In addition, the Company granted 20,832 restricted shares of common stock to its non-employee independent directors, which vest one year from date of grant so long as the director and/or Company does not terminate their service prior to the vesting date.

During 2012, the Company awarded restricted shares of common stock to certain Company key employees which are performance-based grants. Of this award,60%are earned based on 2012 EPS growth, and the remaining40%are earned based on the EPS CAGR for 2012 and 2013. For the60%of shares subject to the 2012 earnings per share growth metric only, the performance conditions were satisfied, resulting in an attainment level of175%of target. This resulted in an additional72,576share grants during thefirst quarter of 2013. For the 40% of shares subject to the 2012-2013 EPS CAGR metric, the performance conditions were satisfied, resulting in an attainment level of 125% of target. This resulted in an additional 16,054 shares granted during the first quarter of 2014.

Information related to restricted shares at September 30, 2014 is as follows:

	Number of Unvested Restricted Shares		Weighted Average Grant Date Fair Value		Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value

Goodwill and Other Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

During the third quarter of 2014, based on a few consecutive quarters of revenue and earnings declines compared to historical levels within the Company's Energy reporting unit, the Company determined that there were indicators of a decline in fair value of the Energy reporting unit, which also may indicate a potential impairment of the recorded goodwill. As such, the Company conducted a Step 1 quantitative goodwill impairment analysis as required by the authoritative accounting literature. The Company utilized both income and market-based approaches, placing a 75% and 25% weighting on each, respectively. Significant management assumptions used under the income approach were a weighted average cost of capital of 13% and an estimated residual growth rate of 3%. In considering the weighted average cost of capital for the reporting unit, management considered the level of risk inherent in the cash flow projections based on historical attainment of its projections and current market conditions. Upon completion of the goodwill impairment test, the Company determined that the fair value of the Energy reporting unit exceeded the carrying value by more than 20%, and thus there was no goodwill impairment. In addition, a 1% reduction in residual growth rate combined with a 1% increase in the weighted average cost of capital would not have changed the conclusions reached under the Step I impairment test.

Changes in the carrying amount of goodwill for the nine months ended September 30, 2014 are summarized as follows:

Facility Closures

Goshen, Indiana facility

In November 2012, the Company announced plans to close its manufacturing facility in Goshen, Indiana, moving production from Goshen to lower-cost manufacturing facilities during 2013. The Company completed the move and ceased operations in Goshen during the fourth quarter of 2013.

In addition, during the three and nine months ended September 30, 2013, the Company incurred approximately $0.5 million and $1.2 million, respectively, of pre-tax non-cash charges related to accelerated depreciation expense as a result of shortening the expected lives on certain machinery, equipment and leasehold improvement assets that the Company no longer utilizes following the facility closure.

São Paulo, Brazil facility

In June 2014, the Company announced the restructuring of its Brazilian business within the Energy reportable segment, including plans to close its manufacturing facility in São Paulo, Brazil by the end of 2014. In connection with this action, the Company recorded charges of approximately $0.5 million, primarily related to severance benefits, which is included in cost of sales in the accompanying consolidated statement of income, for its approximately 60 employees to be involuntarily terminated as a result of this closure.

The Company's manufacturing facility in São Paulo is subject to a lease agreement expiring in 2022. The Company is currently assessing the potential recoverability of its future lease obligations for this facility, and will record an estimate of any future unrecoverable lease obligations upon the cease-use date of the facility.

Sale of Business

On August 5, 2013, the Company announced the sale of its business in Italy within the Packaging reportable segment for cash of approximately $10.3 million. As a result, the Company recorded a pre-tax gain of approximately $10.5 million, of which $7.9 million related to the release of historical currency translation adjustments into income.

New Accounting Pronouncements

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-9, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-9"). ASU 2014-9 requires that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-9 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early adoption prohibited. The Company is in the process of assessing the impact of the adoption of ASU 2014-09 on its consolidated financial statements.

In April 2014, the FASB issued ASU 2014-8, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-8"). ASU 2014-8 changes the criteria for reporting discontinued operations and requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations. ASU 2014-8 is effective for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods, and interim periods within those years, beginning on or after December 15, 2014, with early adoption permitted for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company expects to adopt ASU 2014-08 upon its required effective date.

Acquisitions

Acquisitions

In July 2014, the Company completed the acquisition of Lion Holdings PVT. Ltd. ("Lion Holdings") within the Company's Packaging reportable segment for the amount of approximately $28 million, net of cash acquired. Located in both India and Vietnam, Lion Holdings specializes in the manufacture of highly engineered dispensing solutions and generated approximately $10 million in revenue for the twelve months ended June 30, 2014.

During the first nine months of 2013, the Company completed acquisitions for an aggregate amount of approximately $56 million, net of cash acquired. Of these acquisitions, the most significant are as follows:

• Martinic Engineering, Inc. ("Martinic") within the Company's Aerospace reportable segment is a manufacturer of highly-engineered, precision machined, complex parts for commercial and military aerospace applications, including auxiliary power units, as well as electrical, hydraulic and pneumatic systems located in the United States and generated approximately $13 million in revenue for the twelve months ended December 31, 2012.

• Wulfrun Specialised Fasteners Limited ("Wulfrun") within the Company's Energy reportable segment is a manufacturer and distributor of specialty bolting and CNC machined components for use in critical oil and gas, pipeline and power generation applications located in the United Kingdom and generated approximately $10 million in revenue for the twelve months ended December 31, 2012.

• C.P. Witter Limited ("Witter"), within the Company's Cequent APEA reportable segment, is a manufacturer of highly-engineered towbars and accessories which are distributed through a wide network of commercial dealers located in the United Kingdom, and generated approximately $20 million in revenue for the twelve months ended March 31, 2013.

• The towing technology and business assets of AL-KO GmbH ("AL-KO"), located in both Germany and Finland, and also within the Company's Cequent APEA reportable segment. The acquired assets generated approximately $16 million of revenue for the twelve months ended June 30, 2013. The fair value of the AL-KO net assets exceeded the purchase price, resulting in a bargain purchase gain of approximately $2.9 million, which is included in other income (expense), net in the accompanying consolidated statement of income for the three and nine months ended September 30, 2013.

The results of operations of the aforementioned acquisitions are not significant compared to the overall results of operations of the Company.

Arminak & Associates

During the first quarter of 2012, the Company acquired 70% of the membership interests of Arminak & Associates, LLC ("Arminak") for the purchase price of approximately $67.7 million, which is included in the Company's Packaging reportable segment. The original purchase agreement provided the Company an option to purchase, and Arminak's previous owners an option to sell, the remaining 30% noncontrolling interest at specified dates in the future based on a multiple of future earnings, as defined in the purchase agreement. The put and call options become exercisable during the first quarters of 2014, 2015 and 2016, and the original combination of a noncontrolling interest and a redemption feature resulted in a redeemable noncontrolling interest, which was classified outside of permanent equity on the accompanying consolidated balance sheet.

On March 11, 2014, in lieu of the put and call options in the original purchase agreement, the Company entered into a new agreement to purchase the entire 30% noncontrolling interest in Arminak for a cash purchase price of $51.0 million. The purchase agreement also includes additional contingent consideration of up to $7.0 million, with the amount to be earned based on the achievement of certain levels of 2015 financial performance. In order to estimate the fair value of the contingent consideration, the Company utilized the Monte Carlo valuation method, using variations of expected future payouts given certain significant assumptions including expected revenue and earnings growth, volatility and risk. As these assumptions are not observable in the market, the calculation represents a Level 3 fair value measurement. As of September 30, 2014, the estimated liability for the payout of contingent consideration is $3.1 million. The final contingent consideration is expected to be paid, if earned, in the second quarter of 2016.

As part of purchasing the remaining membership interest, the Company finalized the calculation of the redeemable noncontrolling interest as of March 11, 2014. Changes in the carrying amount of redeemable noncontrolling interest are summarized as follows:

	Noncontrolling interest
	(dollars in thousands)
Beginning balance, December 31, 2013	$	29,480
Distributions to noncontrolling interests	(580		)
Net income attributable to noncontrolling interests	810
Ending balance, March 11, 2014	$	29,710

The difference between the cash purchase price and final redeemable noncontrolling interest as of March 11, 2014 was recorded as a reduction in paid in capital, net of tax, as included in the accompanying consolidated statement of shareholders' equity.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill Disclosure [Text Block]

Goodwill and Other Intangible Assets

During the third quarter of 2014, based on a few consecutive quarters of revenue and earnings declines compared to historical levels within the Company's Energy reporting unit, the Company determined that there were indicators of a decline in fair value of the Energy reporting unit, which also may indicate a potential impairment of the recorded goodwill. As such, the Company conducted a Step 1 quantitative goodwill impairment analysis as required by the authoritative accounting literature. The Company utilized both income and market-based approaches, placing a 75% and 25% weighting on each, respectively. Significant management assumptions used under the income approach were a weighted average cost of capital of 13% and an estimated residual growth rate of 3%. In considering the weighted average cost of capital for the reporting unit, management considered the level of risk inherent in the cash flow projections based on historical attainment of its projections and current market conditions. Upon completion of the goodwill impairment test, the Company determined that the fair value of the Energy reporting unit exceeded the carrying value by more than 20%, and thus there was no goodwill impairment. In addition, a 1% reduction in residual growth rate combined with a 1% increase in the weighted average cost of capital would not have changed the conclusions reached under the Step I impairment test.

Foreign Currency Exchange Rate Risk

As of September 30, 2014, the Company was party to forward contracts to hedge changes in foreign currency exchange rates with notional amounts of approximately $11.0 million. The Company uses foreign currency forward contracts to mitigate the risk associated with fluctuations in currency rates impacting cash flows related to certain payments for contract manufacturing in its lower-cost manufacturing facilities. The foreign currency forward contracts hedge currency exposure between the Mexican peso and the U.S. dollar and the Thai baht and the Australian dollar and mature at specified monthly settlement dates through March 2015. At inception, the Company designated the foreign currency forward contracts as cash flow hedges.

Interest Rate Risk

In December 2012, the Company entered into an interest rate swap agreement to fix the LIBOR-based variable portion of the interest rates on its term loan A facility. The term loan A swap agreement fixes the LIBOR-based variable portion of the interest rate, beginning February 2013, on a total of $175.0 million notional amount at 0.74% and expires on October 11, 2017. At inception, the Company designated the swap agreement as a cash flow hedge.

Financial Statement Presentation

As of September 30, 2014 and December 31, 2013, the fair value carrying amount of the Company's derivatives designated as hedging instruments are recorded as follows:

Long-term Debt

The Company's long-term debt consists of the following:

	September 30, 2014		December 31, 2013
	(dollars in thousands)
Credit Agreement	$	271,430	$	246,130

Less: Current maturities, long-term debt	11,430		10,290
Long-term debt	$	329,690	$	295,450

Credit Agreement

The Company is a party to a credit agreement consisting of a $575.0 million senior secured revolving credit facility, which matures in October 2018 and is subject to interest at London Interbank Offered Rates ("LIBOR") plus 1.50%, and a $175.0 million senior secured term loan A facility, which matures in October 2018 and is subject to interest at LIBOR plus 1.50% (collectively, the "Credit Agreement"). The interest rate spread is based upon the leverage ratio, as defined, as of the most recent determination date. Per the Credit Agreement, the senior secured revolving credit facility permits borrowings denominated in specific foreign currency ("Foreign Currency Loans"), subject to a $75.0 million sub limit.

The Credit Agreement also provides incremental term loan and/or revolving credit facility commitments in an amount not to exceed the greater of $300.0 million and an amount such that, after giving effect to such incremental commitments and the incurrence of any other indebtedness substantially simultaneously with the making of such commitments, the senior secured net leverage ratio, as defined, is no greater than 2.50 to 1.00. The terms and conditions of any incremental term loan and/or revolving credit facility commitments must be no more favorable than the existing credit facility.

Beginning with the fiscal year ending December 31, 2014 (payable in 2015), the Company may be required to prepay a portion of its term loan A facility in an amount equal to a percentage of the Company's excess cash flow, as defined, with such percentage based on the Company's leverage ratio, as defined.

The Company is also able to issue letters of credit, not to exceed $75.0 million in aggregate, against its revolving credit facility commitments. At September 30, 2014 and December 31, 2013, the Company had letters of credit of approximately $21.9 million and $24.1 million, respectively, issued and outstanding.

At September 30, 2014, the Company had $103.0 million outstanding under its revolving credit facility and had $452.1 million potentially available after giving effect to approximately $21.9 million of letters of credit issued and outstanding. AtDecember 31, 2013, the Company had$71.1 millionoutstanding under its revolving credit facility and had$479.8 million potentially available after giving effect to approximately $24.1 million of letters of credit issued and outstanding. However, including availability under its accounts receivable facility and after consideration of leverage restrictions contained in the Credit Agreement, the Company had $366.7 million and $360.3 million at September 30, 2014 and December 31, 2013, respectively, of borrowing capacity available for general corporate purposes.

The debt under the Credit Agreement is an obligation of the Company and certain of its domestic subsidiaries and is secured by substantially all of the assets of such parties. Borrowings under the $75.0 million foreign currency sub limit of the $575.0 million senior secured revolving credit facility are secured by a pledge of the assets of the foreign subsidiary borrowers that are a party to the agreement.  The Credit Agreement also contains various negative and affirmative covenants and other requirements affecting the Company and its subsidiaries, including restrictions on incurrence of debt, liens, mergers, investments, loans, advances, guarantee obligations, acquisitions, assets dispositions, sale-leaseback transactions, hedging agreements, dividends and other restricted payments, transactions with affiliates, restrictive agreements and amendments to charters, bylaws, and other material documents. The terms of the Credit Agreement also require the Company and its subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a maximum leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined) and a minimum interest expense coverage ratio (consolidated EBITDA, as defined, over cash interest expense, as defined). At September 30, 2014, the Company was in compliance with its financial and other covenants contained in the Credit Agreement.

As of September 30, 2014 and December 31, 2013, the Company's Credit Agreement traded at approximately 99.2% and 99.8% of par value, respectively. The valuations of the Credit Agreement were determined based on Level 2 inputs under the fair value hierarchy, as defined.

Receivables Facility

The Company is a party to an accounts receivable facility through TSPC, Inc. ("TSPC"), a wholly-owned subsidiary, to sell trade accounts receivable of substantially all of the Company's domestic business operations. During the second quarter of 2014, the Company amended this $105.0 million facility, reducing the usage fee on amounts outstanding previously ranging from 1.20% or 1.35%, depending on the amounts drawn under the facility, to 1.15%. The amendment also reduced the cost of the unused portion of the facility from 0.40% to 0.35% and extended the maturity date from October 12, 2017 to October 16, 2018.

Under this facility, TSPC, from time to time, may sell an undivided fractional ownership interest in the pool of receivables up to approximately $105.0 million to a third party multi-seller receivables funding company. The net amount financed under the facility is less than the face amount of accounts receivable by an amount that approximates the purchaser's financing costs. The cost of funds under this facility consisted of a 3-month LIBOR-based rate plus a usage fee of 1.15% and 1.20% as of September 30, 2014 and 2013, respectively, and a fee on the unused portion of the facility of 0.35% and 0.40% as of September 30, 2014 and 2013, respectively.

The Company had $66.3 million and $57.0 million outstanding under the facility as of September 30, 2014 and December 31, 2013, respectively, and $27.1 million and $20.2 million, respectively, available but not utilized. Aggregate costs incurred under the facility were $0.3 million and $0.4 million for the three months ended September 30, 2014 and 2013, respectively, and $1.0 million and $1.1 million for the nine months ended September 30, 2014 and 2013, respectively, and are included in interest expense in the accompanying consolidated statement of income. The facility expires on October 16, 2018.

The cost of funds fees incurred are determined by calculating the estimated present value of the receivables sold compared to their carrying amount. The estimated present value factor is based on historical collection experience and a discount rate based on a 3-month LIBOR-based rate plus the usage fee discussed above and is computed in accordance with the terms of the securitization agreement. As of September 30, 2014, the cost of funds under the facility was based on an average liquidation period of the portfolio of approximately 1.7 months and an average discount rate of 1.8%.

Other Bank Debt

The Company's Australian subsidiary is party to a debt agreement which matures on October 31, 2014 and is secured by substantially all the assets of the subsidiary. At September 30, 2014 and December 31, 2013, the balance outstanding under this agreement was approximately $2.2 million and $0.7 million, respectively, at an average interest rate of 4.6% at each of the periods then ended.

In the second quarter of 2014, the Company's Dutch subsidiary entered into a credit agreement consisting of a $12.5 million uncommitted working capital facility agreement which matures on May 29, 2015, is subject to interest at LIBOR plus 2.75% per annum and is guaranteed by TriMas. In addition, this Dutch subsidiary is subject to an overdraft facility in conjunction with the uncommitted working capital facility up to $1.0 million, subject to interest at U.S. dollar prime rate plus 0.75%. No amounts were outstanding on this facility as of September 30, 2014.
