PROPOSAL 1 – ELECTION OF DIRECTORS

The Board is divided into three classes, each class consisting of approximately one-third of the Company’s directors. Class III directors’ terms will expire at the Annual Meeting. Messrs. Nick L. Stanage, Daniel P. Tredwell and Samuel Valenti III have consented to stand for re-election to serve until the 2021 Annual Meeting of Shareholders. If any of them should become unavailable, the Board may designate a substitute nominee. In that case, the proxy holders named as proxies in the accompanying proxy card will vote for the Board’s substitute nominee.

THE COMPANY’S BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” EACH OF THE THREE DIRECTORS LISTED BELOW WHO STANDS FOR RE-ELECTION, TO SERVE UNTIL THE 2021 ANNUAL MEETING.

Vote Required

The three individuals who receive the most votes cast at the Annual Meeting will be elected as directors, provided a quorum of at least a majority of the outstanding shares of the Company’s common stock (the “Common Stock”) is represented at the meeting. However, we have adopted a majority voting policy that is applicable in uncontested director elections. This means that the plurality standard will determine whether a director nominee is elected, but our majority voting policy will further require that the number of votes cast “for” a director must exceed the number of votes “withheld” from that director or the director must submit his or her resignation. The Board, taking into account the recommendation of the Governance and Nominating Committee, would then determine whether to accept or reject the resignation. A proxy card marked “Withhold” or “For All Except” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated. Abstentions and broker non-votes will each be counted as present for purposes of determining the presence of a quorum, but will have no effect on the election of directors.

Additional information regarding the directors and director nominees of the Company is set forth below.

Directors and Director Nominees

The Board currently consists of eight members divided into three classes serving staggered terms.

Director Background, Experience and Qualifications

The following sets forth the business experience during at least the past five years of each director nominee and each of the directors whose term of office will continue after the Annual Meeting.

In addition, the following includes a brief discussion of the specific experience, qualifications, attributes, and skills that led to the conclusion that the directors and nominees should serve on the Board at this time. The Governance and Nominating Committee considers the experience, mix of skills, and other qualities of the existing Board to ensure appropriate Board composition. The Governance and Nominating Committee believes that directors must have demonstrated excellence in their chosen field, high ethical standards and integrity, and sound business judgment. In addition, it seeks to ensure the Board includes members with diverse backgrounds, skills and experience, including appropriate financial and other expertise relevant to the Company’s business.

As more fully reflected in the chart and description below, the Board believes that the directors and nominees have an appropriate balance of knowledge, experience, attributes, skills, and expertise as a whole to ensure the Board appropriately fulfills its oversight responsibilities and acts in the best interests of shareholders. The Board believes that each director satisfies its criteria for demonstrating excellence in his or her chosen field, high ethical standards and integrity, and sound business judgment. In addition, the Board has seven independent directors in accordance with the applicable independence rules of Nasdaq, and such directors are also independent of the influence of any particular shareholder or shareholder groups whose interests may diverge from the interests of the shareholders as a whole. Further, each director or nominee brings a strong background and set of skills to the Board, giving the Board, as a whole, competence and experience in a wide variety of areas.

Herbert Parker on the Company’s slate for election as a Class II director at the 2017 Annual Meeting of the Company’s shareholders and to recommend, support and solicit proxies for the election of Mr. Parker in the same manner as for the Company’s other nominees standing for election to the Board at the 2017 Annual Meeting of the Company’s shareholders.

Engaged is also subject to standstill provisions under the Agreement. Such provisions generally remain in effect until 10 days prior to the expiration of the advance notice period for the nomination of directors at the Company’s 2019 Annual Meeting (the “Standstill Period”). These provisions restrict Engaged’s ability to engage in certain proxy solicitations, make certain shareholder proposals, call meetings of shareholders, solicit consents from shareholders, obtain additional representation on the Board, or seek to remove any of the Company’s directors.

The Agreement further provides that, during the Standstill Period, except as specified in the Agreement, Engaged will cause all shares of Common Stock then beneficially owned by Engaged or its affiliates to be present for quorum purposes and to be voted as recommended by the Board on any matter to be voted on at any annual meeting of shareholders during the Standstill Period.

The Board of Directors and Committees

Since June 2002, the Company has separated the roles of the Board chair and chief executive officer. The Board believes that separating these roles offers distinct benefits to the Company, including curtailing the potential for conflict of interest and facilitating objective Board evaluation of the Company’s management. Mr. Valenti has served as Board chair since 2002 and has been an independent director since November 2008.

Board of Directors Risk Management Functions

As part of its oversight function, the Board monitors how management operates the Company, in part via its committee structure. When granting authority to management, approving strategies, and receiving management reports, the Board considers, among other things, the risks and vulnerabilities the Company faces. The Audit Committee considers risk issues associated with the Company’s overall financial reporting, disclosure process, and legal compliance, as well as reviewing policies on risk control assessment and accounting risk exposure. In addition to its regularly scheduled meetings, the Audit Committee meets with the corporate audit team, and the independent registered public accounting firm in executive sessions at least quarterly, and with the general counsel and chief compliance officer as determined from time to time by the Audit Committee. Each of the Compensation Committee and the Governance and Nominating Committee considers risk issues associated with the substantive matters addressed by the committee.

During 2017, the Board held five meetings, the Audit Committee held six meetings, the Compensation Committee held three meetings, and the Governance and Nominating Committee held two meetings.

Corporate Governance

The Company’s Board of Directors currently consists of eight directors, divided into three classes as equal in number as possible. The members of each class serve for staggered, three year terms. Upon the expiration of the term of a class of directors, directors in that class may be asked to stand for re-election for a three year term at the annual meeting in the year in which their term expires.

Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the Company’s directors.

The Board has determined, after considering all of the relevant facts and circumstances, that Messrs. Gabrys, Miller, Parker, Stanage, Tredwell and Valenti, and Ms. Gougarty are “independent” from management in accordance with the Nasdaq listing standards and the Company’s Corporate Governance

Guidelines. To be considered independent, the Board must determine that a director does not have any direct or indirect material relationships with the Company and must meet the criteria for independence set forth in the Company’s Corporate Governance Guidelines. With respect to Mr. Valenti, who is also a member of the board of directors of Horizon, the Board determined that his service on the board of directors of Horizon does not impair his independence after giving consideration to the transitional relationships between the companies that were put in place in connection with the Spin-Off, including pursuant to a Separation and Distribution Agreement, a Tax Sharing Agreement, an Employee Matters Agreement, a Transition Services Agreement, and a Noncompetition and Nonsolicitation Agreement. If discussions arise regarding current or future relationships between the Company and Horizon, Mr. Valenti would not participate in such discussions or any related Board approvals. With respect to Mr. Tredwell, the Board considered that the Company has agreed to pay certain fees related to an ongoing environmental matter to Heartland Industrial Partners, L.P. (in an amount less than $120,000).

During 2017, all current directors attended at least 75%, in aggregate, of the meetings of the Board and all committees of the Board on which they served. All of the current directors who were serving on the Board at the time of the 2017 Annual Meeting of Shareholders attended the 2017 Annual Meeting. All directors are expected to attend all meetings, including the annual meeting. In addition to attending Board and committee meetings, directors fulfill their responsibilities by consulting with the president and chief executive officer and other members of management on matters that affect the Company.

Independent directors hold regularly scheduled executive sessions in which independent directors meet without the presence of management. These executive sessions generally occur around regularly scheduled meetings of the Board. For more information regarding the Company’s Board and other corporate governance procedures, see “Corporate Governance.” For information on how you can communicate with the Company’s non-management directors, see “Communicating with the Board.”

Audit Committee. The Audit Committee is responsible for providing independent, objective oversight and review of the Company’s auditing, accounting and financial reporting processes, including reviewing the audit results and monitoring the effectiveness of the Company’s internal audit function. In addition, the Audit Committee is responsible for (1) selecting the Company’s independent registered public accounting firm, (2) approving the overall scope of the audit, (3) assisting the Board in monitoring the integrity of the Company’s financial statements, the independent registered public accounting firm’s qualifications and independence, the performance of the Company’s independent registered public accounting firm and the Company’s internal audit function, and compliance with relevant legal and regulatory requirements, (4) annually reviewing the Company’s independent registered public accounting firm’s report describing the auditing firm’s internal quality control procedures and any material issues raised by the most recent internal quality control review, or peer review, of the auditing firm, (5) discussing the annual audited financial and quarterly statements with management and the independent registered public accounting firm, (6) discussing earnings press releases and any financial information or earnings guidance provided to analysts and rating agencies, (7) discussing policies with respect to risk assessment and risk management, (8) meeting separately and periodically, with management, internal auditors, and the independent registered public accounting firm, (9) reviewing with the independent auditor any audit problems or difficulties and management’s responses, (10) setting clear hiring policies for employees or former employees of the independent registered public accounting firm, (11) handling such other matters that are specifically delegated to the Audit Committee by applicable law or regulation or by the Board, and (12) reporting regularly to the full Board. See “Report of the Audit Committee.” The Audit Committee’s charter is available on the Company’s website, www.trimascorp.com, in the Corporate Governance subsection of the Investor page. The Audit Committee last updated its charter on November 5, 2015.

Each of the directors on the Audit Committee is financially literate. The Board has determined that each of Messrs. Gabrys, Miller, Parker and Tredwell qualifies as an “audit committee financial expert” within the meaning of Securities and Exchange Commission (“SEC”) regulations and that each member on the Audit

PROPOSAL 1 – ELECTION OF DIRECTORS

Committee has the accounting and related financial management expertise required by the Nasdaq listing standards and that each is “independent” from management in accordance with Nasdaq listing standards and the Company’s Corporate Governance Guidelines.

Compensation Committee. The Compensation Committee is responsible for developing and maintaining the Company’s compensation strategies and policies, including (1) reviewing and approving the Company’s overall executive and director compensation philosophy and the executive and director compensation programs to support the Company’s overall business strategy and objectives, (2) overseeing the management continuity and succession planning process (except as otherwise within the scope of the Governance and Nominating Committee) with respect to the Company’s officers, and (3) preparing any report on executive compensation required by the applicable rules and regulations of the SEC and other regulatory bodies.

The Compensation Committee is responsible for monitoring and administering the Company’s compensation and employee benefit plans and reviewing, among other things, base salary levels, incentive awards, and bonus awards for officers and key executives, and such other matters that are specifically delegated to the Compensation Committee by applicable law or regulation, or by the Board. The Compensation Committee’s charter reflects such responsibilities and is available on the Company’s website, www.trimascorp.com, in the Corporate Governance subsection of the Investors page. The Compensation Committee last updated its charter on November 5, 2015. Each of the directors on the Compensation Committee is “independent” from management in accordance with Nasdaq listing standards (including those standards particular to Compensation Committee membership) and the Company’s Corporate Governance Guidelines. See also “Compensation Discussion and Analysis - Role of the Compensation Committee.” The Compensation Committee is entitled to delegate certain of its responsibilities to subcommittees of the Compensation Committee or other committees of the Board, subject to applicable law.

Governance and Nominating Committee. The Governance and Nominating Committee is responsible for identifying and nominating individuals qualified to serve as Board members and recommending directors for each Board committee. Generally, the Governance and Nominating Committee will re-nominate incumbent directors who continue to satisfy its criteria for membership on the Board, who it believes will continue to make important contributions to the Board, and who consent to continue their service on the Board.

In recommending candidates to the Board, the Governance and Nominating Committee reviews the experience, mix of skills, and other qualities of a nominee to assure appropriate Board composition after taking into account the current Board members and the specific needs of the Company and the Board. The Board looks for individuals who have demonstrated excellence in their chosen field, high ethical standards and integrity, and sound business judgment. The Governance and Nominating Committee does not have a formal policy with respect to diversity; however, the Board and the Governance and Nominating Committee believe that it is essential that the Board members represent diverse viewpoints. As required by Nasdaq, SEC, or such other applicable regulatory requirements, a majority of the Board will be comprised of independent directors.

The Governance and Nominating Committee generally relies on multiple sources for identifying and evaluating nominees, including referrals from the Company’s current directors and management. The Governance and Nominating Committee may also work with a third-party search firm to identify potential candidates to serve on the Board. The Governance and Nominating Committee does not solicit director nominations, but will consider recommendations by shareholders with respect to elections to be held at an annual meeting, so long as such recommendations are sent on a timely basis to the corporate secretary of the Company and are in accordance with the Company’s bylaws. The Governance and Nominating Committee will evaluate nominees recommended by shareholders against the same criteria. The Company did not receive any nominations of directors by shareholders for the Annual Meeting. See “How and when may I submit a shareholder proposal or director nomination for the 2019 Annual Meeting?” for more information.

The Board may accept or reject such resignation in its discretion after consultation with the Governance and Nominating Committee. The Board has not established term limits for the directors.

Assessment of Board and Committee Performance. The Board evaluates its performance annually. In addition, each Board committee performs an annual self-assessment to determine its effectiveness. The results of the Board and committee self-assessments are discussed with the Board and each Committee, respectively.

DIRECTOR COMPENSATION

The Compensation Committee is responsible for reviewing director compensation and making recommendations to the Board with respect to that compensation, as appropriate. The Compensation Committee and Board believe that directors should receive a mix of cash and equity over their tenure. The combination of cash and equity compensation is intended to provide incentives for directors to continue to serve on the Board and to attract new directors with outstanding qualifications. Directors may make an annual election to defer receipt of Board compensation, provided the election is made prior to the fiscal year in which the deferral is effective.

Annual Cash Retainer and Meeting Fees. For 2017, each independent director received an annual cash retainer of $100,000 and a meeting fee of $1,000 for each Board or committee meeting attended. The chair of the Board and of each of the Audit, Compensation, and Governance and Nominating Committees received an additional annual cash retainer in the amounts of $125,000, $15,000, $10,000, and $5,000, respectively.

The Company implemented a director retainer share election program effective January 1, 2014, to permit directors to make an annual election to receive unrestricted stock for deferred or non-deferred compensation for board service in lieu of cash at the time payment is made each quarter. For 2017, three of the seven independent directors (Ms. Gougarty and Messrs. Miller and Parker) elected to defer receipt of all or part of their Board compensation.

Equity Compensation. As part of the independent directors’ annual compensation package, each independent director receives an annual grant on March 1st of restricted stock units with a grant date fair market value of $100,000 (subject to rounding), with each grant generally subject to the director’s continued service on the Board for a one-year vesting period. In March 2017, the Company made the annual grant to each of the independent directors on the same terms.

Director Stock Ownership. We have established stock ownership guidelines for our independent directors to more closely tie their interests to those of shareholders. Under these guidelines, all such directors are required to own, within five years after initial election to the Board as an independent director, shares of Company stock having a value equal to three times their annual cash retainer (excluding any additional retainers for Board and committee chair service). Unrestricted stock, service-based restricted stock units, and vested in-the-money options are counted toward fulfillment of this ownership requirement. As of December 31, 2017, each independent director was in compliance with his or her stock ownership requirement. If an independent director does not meet the stock ownership guidelines, the Compensation Committee may consider such fact in determining the award of future equity awards to such director.

Indemnification. The Company has entered into indemnification agreements with each of its directors. These agreements require the Company to indemnify such individuals for certain liabilities to which they may become subject as a result of their affiliation with the Company.

Other. The Company reimburses all directors for expenses incurred in attending Board and committee meetings. The Company does not provide any perquisites to directors.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The Audit Committee represents and assists the Board in fulfilling its responsibilities for general oversight of the integrity of the Company’s financial statements, the Company’s compliance with legal and regulatory requirements, the independent registered public accounting firm’s qualifications and independence, the performance of the Company’s internal audit function and independent registered public accounting firm, and risk assessment and risk management. The Audit Committee manages the Company’s relationship with the independent registered public accounting firm (which reports directly to the Audit Committee). The Audit Committee has the authority to obtain advice and assistance from outside legal, accounting, or other advisors as the Audit Committee deems necessary to carry out its duties and receives appropriate funding as determined by the Audit Committee from the Company for such advice and assistance.

The Company’s management is primarily responsible for the Company’s internal control and financial reporting process. The Company’s independent registered public accounting firm, Deloitte, is responsible for performing an independent audit of the Company’s consolidated financial statements and issuing opinions on the conformity of reporting those audited financial statements with United States generally accepted accounting principles and the effectiveness of the Company’s internal control over financial reporting. The Audit Committee monitors the Company’s financial reporting process and reports to the Board on its findings.

In this context, the Audit Committee hereby reports as follows:

| 1. | The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2017 with the Company’s management;

| 2. | The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by Auditing Standard No. 1301 issued by the Public Company Accounting Oversight Board (“PCAOB”);

| 3. | The Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding its independence; and

| 4. | Based on the review and discussions referred to in paragraphs 1 through 3 above, the Audit Committee recommended to the Board, and the Board has approved, that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, for filing with the SEC.

The undersigned members of the Audit Committee have submitted this Report to the Board.

PROPOSAL 2 — RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE COMPANY’S BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF DELOITTE AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2018.

The Audit Committee has appointed Deloitte as the independent registered public accounting firm to audit the Company’s consolidated financial statements for the fiscal year ending December 31, 2018.Deloitte served as the Company’s independent registered public accounting firm for the fiscal years ending December 31, 2017 and December 31, 2016. Representatives of Deloitte are expected to attend the Annual Meeting, where they will be available to respond to appropriate questions and, if they desire, make a statement.

The appointment of Deloitte as the independent registered public accounting firm for the Company is being presented to the shareholders for ratification. The ratification of the appointment of the independent registered public accounting firm requires the affirmative vote of the holders of a majority of the total shares of Common Stock present in person or represented by proxy, provided that a quorum of at least a majority of the outstanding shares are present or represented at the meeting. If you abstain from voting on this matter, your abstention will have the same effect as a vote against the matter. If you hold your shares through a broker and you do not instruct the broker on how to vote on this “routine” proposal, your broker will nevertheless have authority to vote your shares on this “routine” proposal in your broker’s discretion. Proxies submitted pursuant to this solicitation will be voted “FOR” the ratification of Deloitte as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018, unless specified otherwise.

Fees Paid to Independent Auditor

The following table presents fees billed by Deloitte for professional audit services rendered related to the audits of the Company’s annual financial statements for the years ended December 31, 2017 and 2016, respectively, and fees for other services rendered during those periods.

| 2017 ($) | 2016 ($)
Audit Fees |  | 1,030,000 |  |  | 1,100,000 |
Audit-related Fees |  | 100,000 |  |  | — |

All Other Fees |  | — |  |  | — |
Total |  | 1,700,000 |  |  | 1,430,000 |

Audit and Audit-Related Fees

Integrated audit fees billed for services rendered in connection with the audit of the Company’s annual financial statements and the effectiveness of the Company’s internal control over financial reporting were approximately $1.0 million for 2017 and $1.1 million for 2016. In 2017, audit-related fees of $0.1 million were incurred primarily related to procedures performed in connection with the Company’s debt refinance.

Tax Fees

TriMas Corporation

on the Company’s current and future results. Except for the amounts disclosed above, there were no tax fees billed by Deloitte during 2017 or 2016, as the Company retained another firm to provide tax advice.

The Audit Committee has determined that the rendering of all non-audit services by Deloitte in 2017 and in 2016 is compatible with maintaining auditor independence.

We have been advised by Deloitte that neither the firm, nor any member of the firm, has any financial interest, direct or indirect, in any capacity in the Company or its subsidiaries.

Policy on Audit Committee Pre-Approval of Audit and Non-Audit Services of Independent Registered Public Accounting Firm

The Audit Committee is responsible for appointing, setting compensation and overseeing the work of the independent registered public accounting firm. The Audit Committee has established a policy regarding pre-approval of all audit and non-audit services provided by the independent registered public accounting firm.

On an ongoing basis, management communicates specific projects and categories of service for which the advance approval of the Audit Committee is requested. The Audit Committee reviews these requests and advises management if the committee approves the engagement of the independent registered public accounting firm. No services are undertaken which are not pre-approved. On a periodic basis, management reports to the Audit Committee regarding the actual spending for such projects and services compared to the approved amounts. All of the services provided by Deloitte, our independent auditor in 2017 and 2016, including services related to audit, audit-related fees, tax fees, and all other fees described above, were approved by the Audit Committee under its pre-approval policies.

The Audit Committee’s policies permit the Company’s independent accountants, Deloitte, to provide audit-related services, tax services and non-audit services to the Company, subject to the following conditions:

| 1. | Deloitte will not be engaged to provide any services that may compromise its independence under applicable laws and regulations, including rules and regulations of the SEC and the PCAOB;

| 2. | Deloitte and the Company will enter into engagement letters authorizing the specific audit-related services or non-audit services and setting forth the cost of such services;

| 3. | The Company is authorized, without additional Audit Committee approval, to engage Deloitte to provide (a) audit-related and tax services, including due diligence and tax planning related to acquisitions where Deloitte does not audit the target company, to the extent that the cost of such engagement does not exceed $250,000, (b) due diligence and tax planning related to acquisitions where Deloitte audits the target company, to the extent the cost of such engagement does not exceed $20,000, and (c) services not otherwise covered by (a) or (b) above to the extent the cost of such engagements does not exceed $150,000; provided, however, that the aggregate amount of all such engagements under (a), (b) and (c) may not exceed $350,000 in any calendar quarter; and

| 4. | The Chair of the Audit Committee will be promptly notified of each engagement, and the Audit Committee will be updated quarterly on all engagements, including fees.

PROPOSAL 3 - APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION PAID TO THE COMPANY’S NAMED EXECUTIVE OFFICERS

THE COMPANY’S BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION PAID TO THE COMPANY’S NAMED EXECUTIVE OFFICERS

As required pursuant to Section 14A of the Securities Exchange Act of 1934, or the Exchange Act, the Company is providing shareholders with an advisory (non-binding) vote to approve the compensation paid to our “NEOs” as disclosed in this Proxy Statement. This advisory vote is commonly known as a “Say-on-Pay” vote. At the 2017 Annual Meeting of Shareholders, a majority of the votes cast on a proposal regarding the frequency for future Say-on-Pay votes approved the Board’s recommendation to hold future Say-on-Pay votes on an annual basis. The Company adopted an annual Say-on-Pay vote program in 2017 after considering these voting results. The Company previously adopted a triennial Say-on-Pay vote program and prior Say-on-Pay votes took place at the 2014 and 2017 Annual Meetings of Shareholders, during each of which over 99% of the shareholders who voted on or abstained with respect to the Say-on-Pay proposal (disregarding broker non-votes) approved our Say-on-Pay resolution.

At its first meeting held after our 2017 Say-on-Pay vote, the Compensation Committee reviewed the voting results described above. After taking into consideration the strong level of support expressed by our shareholders for the executive compensation program for our then-NEOs, the Compensation Committee decided to continue to apply the same guiding philosophy and principles to subsequent decisions and when adopting subsequent policies regarding NEO compensation. No changes have been made to our executive compensation program specifically in reaction to the 2017 Say-on-Pay vote. The Compensation Committee also has continued to monitor voting policy changes adopted by our institutional shareholders and their advisors since 2017, and expects to continue to take those voting policies into account when considering changes to our executive compensation program.

2017 Compensation Program Highlights

As described in the Compensation Discussion and Analysis within this Proxy Statement, our NEOs are rewarded when defined financial and operational performance results are achieved, and when value is created for our shareholders. Our Compensation Committee believes that our compensation program is effective in implementing our executive compensation philosophy and establishing a link between compensation and shareholder interests.

Highlights of our compensation program include the following:

| • | A substantial percentage of each NEO’s target total direct compensation is variable, and consists of incentives that can be earned for achieving annual and long-term performance goals. Our program is weighted toward pay-for-performance and variable compensation to reinforce our philosophy of compensating our executives when they and the Company are successful in ways that support shareholder interests.

| • | Each year, the Compensation Committee establishes performance measures intended to focus executives on the most important Company objectives.

2018 Proxy Statement | I | 17

TABLE OF CONTENTS

TriMas Corporation

| • | In determining the compensation components for each NEO for 2017, the Compensation Committee generally focused on market values at the size-adjusted median of our peer group. The market information is considered a reference point rather than policy for reviewing competitiveness.

| • | Our expectations for stock ownership align executives’ interests with those of our shareholders, and all of the NEOs have exceeded their requirements.

| • | The Company’s clawback policy permits the Compensation Committee to recoup or rescind variable compensation to executives, including NEOs, under certain situations, including restatement of financial results.

| • | Our Compensation Committee has retained an independent compensation consultant to advise it with respect to executive and non-employee director compensation matters.

| • | We do not have employment agreements with our executives.

| • | We do not permit “underwater” stock options or stock appreciation rights to be repriced without stockholder approval.

| • | The Company’s anti-hedging policy prohibits the Board of Directors and the Company’s executives, including NEOs, from purchasing any financial instrument that is designed to hedge or offset any decrease in the market value of the Common Stock, including prepaid variable forward contracts, equity swaps, collars and exchange funds.

| • | The Company’s anti-pledging policy prohibits the Board of Directors and the Company’s executives, including NEOs, from pledging with respect to the Company’s Common Stock.

Shareholder Support

We are asking our shareholders to indicate their support for our NEOs’ compensation as described in this Proxy Statement. This proposal gives our shareholders the opportunity to express their views on the compensation of our NEOs. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the philosophy, policies and practices described in this Proxy Statement. Accordingly, we ask our shareholders to vote “FOR” the following resolution at the Annual Meeting:

“RESOLVED, that the Company’s shareholders approve, on an advisory basis, the compensation paid to the Company’s named executive officers, as disclosed in the Compensation Discussion and Analysis, the compensation tables and the related narrative and other disclosures in this Proxy Statement.”

As an advisory vote, this proposal is not binding on the Company. However, our Compensation Committee and Board value the opinions of our shareholders and expect to consider the outcome of the vote when making future compensation decisions regarding the Company’s NEOs. The next Say-on-Pay vote is expected to be held at our 2019 Annual Meeting.

EXECUTIVE COMPENSATION — COMPENSATION DISCUSSION AND ANALYSIS

Introduction

This Compensation Discussion and Analysis (“CD&A”) describes and analyzes the executive compensation program in place at the Company for our NEOs for 2017, which NEOs (our only executive officers serving during 2017) are:

| (1) | Thomas A. Amato - President and Chief Executive Officer;

| (2) | Robert J. Zalupski - Chief Financial Officer; and

| (3) | Joshua A. Sherbin - Senior Vice President, General Counsel, Chief Compliance Officer and Corporate Secretary.

Your understanding of our executive compensation program is important to the Company. The goal of this CD&A is to explain:

| • | Our compensation philosophy and objectives for our NEOs in 2017;

| • | The respective roles of our Compensation Committee (the “Committee”), the Committee’s external executive compensation consultant, and management in the 2017 executive compensation process;

| • | The key components of our 2017 executive compensation program and the successes and achievements our program is designed to reward;

| • | How the decisions we made in the 2017 executive compensation process align with our executive compensation philosophy and objectives; and

| • | How our NEOs’ 2017 compensation aligned with both our financial and operational performance and our shareholders’ long-term investment interests.

2017 Executive Summary

Philosophy and Objectives of Executive Compensation Program

Our executive compensation philosophy is to employ programs that help attract and retain key leaders, motivate executives to continuously strive to improve both our short-term and long-term financial and operating positions, and reward financial and operating achievement by delivering pay that varies appropriately with the actual performance results achieved. Our objectives are to align our executives’ compensation interests with the investment interests of our shareholders and encourage our executives to make decisions that will increase shareholder value over the longer-term. The Company attempts to achieve its philosophy and objectives by establishing performance criteria for its executive officers and by linking compensation to financial performance goals.

2017 Highlights

2017 was a transformational year for TriMas. In July 2016, Thomas Amato was appointed president and chief executive officer, and by the end of that year, we launched the new TriMas Business Model (“TBM”) with increased business connectivity and improved analytics to drive future performance. The TBM provides a standardized set of processes used to drive results across our multi-industry businesses. It is a platform to set near- and long-term performance objectives and goals, including safety, financial and talent development, measure against defined objectives, and utilize a reliable communication and escalation process that provides for flexibility and adjustments if market expectations change. We believe the TBM connects our operations, and allows us to benefit from sharing best practices across each of our businesses.

2018 Proxy Statement | I | 23

TABLE OF CONTENTS

TriMas Corporation

The TBM helped to drive improvement in our performance in 2017. For example, we rationalized 13 locations, streamlined fixed expenses and selling, general and administrative expenses in certain of our businesses experiencing softer end markets, and increased our focus on optimizing net working capital. We believe these actions provided an economic benefit to us, augmenting our cash conversion characteristics and performance overall. We will continue to rely on the TBM to drive continuous improvement and employee motivation to better manage our operations and to unlock TriMas’ value potential. We believe that these changes, as well as refinement of the Company’s strategies, will position TriMas for continued earnings expansion and enhanced returns.

During 2017, the management team achieved the following, as detailed below:

| • | Increased net sales approximately 3.0% to $817.7 million, as sales increased in all four reportable segments as compared to 2016;

| • | Increased operating profit to $88.5 million, while improving operating profit margin, as compared to an operating loss in 2016;

| • | Increased net cash provided by operating activities by 49.2% to $120.1 million compared to 2016;

| • | Reduced total debt by $71.6 million, or 19.1%, to $303.1 million compared to December 31, 2016;

| • | Reduced our leverage ratio to 1.9x as defined by our current credit agreement and ended 2017 with $359.7 million of cash and aggregate availability under our revolving credit and accounts receivable facilities; and

| • | Refinanced our debt, enhancing our capital structure, while also extending our maturity date to 2025 and locking-in fixed rate debt at favorable long-term rates.

In addition, TriMas’ management team also took several proactive actions in 2017 to enhance our future. We continued to invest in the Packaging segment, adding incremental capacity in the new plant in San Miguel de Allende, Mexico and developing product innovations such as several new lotion pumps and trigger sprayers for e-Commerce applications. In the Aerospace segment, we improved fastener manufacturing efficiencies and on-time delivery, enhancing both sales and profitability. And finally, in the new Specialty Products segment (combining the former Engineered Components and Energy segments), we invested in new forging capacity for steel cylinders and received extension of anti-dumping protection for Department of Transportation-certified steel cylinders. In addition, management continued to proactively reduce costs and improve efficiencies in our energy-facing businesses.

In summary, 2017 was a year of solid, improved performance, as we achieved our internal earnings per share plan and exceeded our cash flow targets. As we move forward throughout 2018, we remain focused on utilizing our TBM to drive performance, enhancing long-term growth through innovation, leveraging enterprise-wide cost optimization opportunities and continuing our relentless commitment to cash conversion to drive long-term shareholder value.

Executive Compensation Best Practices

Below we highlight certain executive compensation practices that support the needs of our business, drive performance and align with our shareholders’ long-term interests. A summary of what we do and do not do in that regard follows.

Effective Corporate Governance Reinforces Our Compensation Program

| WHAT WE DO |  | WHAT WE DON’T DO
✔ | Pay for Performance - We tie pay to performance. The majority of NEO pay is not guaranteed but is generally conditioned upon the achievement of predetermined financial goals related to corporate and business unit performance. |  | ✘ |  | No Employment Contracts - We do not have employment contracts with our NEOs.
✔ | Mitigate Undue Risk - Our compensation practices are designed to discourage excessive risk-taking as related to performance and payout under our compensation programs. |  | ✘ |  | No Excise Tax Gross-Ups Upon Change-of-Control - We do not provide for excise tax gross-ups on change-of-control payments.
✔ | Reasonable Executive Severance/Change-of-Control Benefits - Our post-employment and change-of-control severance benefits are designed to be consistent with competitive market practice. |  | ✘ |  | No Repricing Underwater Stock Options or Stock Appreciation Rights Without Shareholder Approval - We do not permit underwater stock options or stock appreciation rights to be repriced without shareholder approval.
✔ | Stock Ownership Guidelines - Our guidelines for stock ownership align executives’ interests with those of our shareholders. Each NEO has exceeded this stock ownership requirement. |  | ✘ |  | No Hedging Transactions, Short Sales or Pledging - Our policies prohibit executives, including the NEOs, and directors from engaging in hedging, short sales or pledging with respect to the Company’s Common Stock.
✔ | Regular Review of Share Utilization - We evaluate share utilization by reviewing the dilutive impact of equity compensation on our shareholders and the aggregate shares awarded annually as a percentage of total outstanding shares. |  |  |  |
✔ | Review Tally Sheets - The Committee reviews tally sheets for our NEOs to ensure they have a clear understanding of the impact of various decisions, including possible payments under various termination scenarios prior to making annual executive compensation decisions. |  |  |  |
✔ | Double Trigger Change-of-Control Severance Benefits - Our Executive Severance/Change-of-Control Policy provides for payment of cash severance and vesting of equity awards after a change-of-control only if an executive experiences a qualifying termination of employment within a limited period following the change-of-control. |  |  |  |
✔ | Independent Compensation Consulting Firm - The Committee benefits from its utilization of an independent compensation consulting firm which provides no other services to the Company. |  |  |  |

Summary of Key Compensation Decisions and Outcomes for 2017

The key decisions the Committee made for 2017 are summarized below and discussed in greater detail in the remainder of this CD&A:

Base Salary Adjustments

Base pay for the NEOs was not adjusted in 2017.

Short-Term Incentive Program

| • | For fiscal year 2017, the short-term incentive program (“STI”) for our NEOs other than Mr. Zalupski was subject to initial funding based on achievement of a threshold level of recurring operating profit. The Committee then utilized the following underlying performance measures and weightings for our NEOs (including Mr. Zalupski) to evaluate and determine final payouts for the year: operating profit at 70%, and cash flow at 30%.

| • | The target incentive award percentages for Messrs. Zalupski and Sherbin remained unchanged from 2016. Mr. Amato began his participation in our STI for 2017 after joining the Company in July 2016.

| • | Based on Company 2017 performance, the initial funding threshold was satisfied. The 2017 STI payout was earned at 124.2% of target by each of our NEOs.

Long-Term Incentive Program

In 2017, the Committee granted performance stock units (“PSUs”) and service-based restricted stock units (“RSUs”) to the NEOs. For each NEO, his total long-term incentive (“LTI”) target award value was allocated equally between these two vehicles, and all awards earned are settled in shares. In particular:

| • | In February 2017, the Committee approved RSU and PSU awards to the NEOs. The RSUs generally vest in three equal installments on the first three anniversaries of the grant date of the award. The PSUs are subject to a performance period of 36 months. These PSU awards are subject to Relative Total Shareholder Return (“RTSR”) and Earnings Per Share Cumulative Average Growth Rate (“EPS CAGR”) performance measures, as further described below.

| • | For previously granted PSUs, the 2015 to 2017 PSU cycle was completed at the end of 2017 and, based on Company performance, the initial funding threshold was satisfied. Based on performance results for the RTSR metric, awards were earned at 126.9% of target and vested on March 1, 2018, as further described below. Mr. Amato did not receive this grant of PSUs in 2015 as he did not join the Company until 2016.

Results and Consideration of 2017 Shareholder Say-on-Pay Vote

At the Annual Meeting of Shareholders held on May 11, 2017, more than 99% of the shareholders who voted on or abstained with respect to the Say-on-Pay proposal (disregarding broker non-votes) approved the compensation of our then-NEOs.

In light of this vote outcome, which was considered by the Committee in its first meeting following the 2017 Annual Meeting of Shareholders, as well as the Committee’s ongoing program evaluation, the Committee views its 2017 decisions regarding various aspects of the compensation program as consistent with the overall philosophy and structure of the program that has been supported by our shareholders. As a result, the Committee did not make any changes to the executive compensation program for 2017 that were based specifically on the results of our 2017 Say-on-Pay vote.

The Company previously conducted its Say-on-Pay votes every three years. However, a majority of the shareholders who voted on the frequency for future Say-on-Pay votes at the 2017 Annual Meeting of Shareholders approved annual advisory Say-on-Pay votes. In alignment with the shareholder

26 | I | 2018 Proxy Statement

TABLE OF CONTENTS

EXECUTIVE COMPENSATION — COMPENSATION DISCUSSION AND ANALYSIS

recommendation, an advisory vote on the Company’s NEO compensation is currently expected to be submitted to shareholders for vote at every annual meeting. The next advisory Say-on-Pay vote is expected to be held in 2019, and we expect to hold the next required vote on the frequency of future Say-on-Pay votes in 2023.

2017 Executive Compensation Program Description

Overview of Key 2017 Program Elements

Each year, our Committee works closely with the Company’s leadership team to refine our executive compensation program, to clearly articulate its objectives to our executives and to emphasize our focus on performance-based compensation so that executives are rewarded for results that create long-term shareholder value.

Pay for Performance

A meaningful percentage of each NEO’s target total direct compensation is variable, consisting of STI awards and LTI awards. The actual amounts realized from the incentive awards depend on performance results, consistent with our belief that a substantial percentage of each NEO’s compensation should be tied to Company performance. The charts below reflect information for all reported NEOs. The mix of target compensation for 2017 for Mr. Amato and the average for the other NEOs are as follows:

2018 Proxy Statement | I | 27

TABLE OF CONTENTS

TriMas Corporation

The main elements of our compensation structure and how each supports our compensation philosophy and objectives are summarized in the following chart:

| Principal 2017 Compensation Elements
| Element | Description | Performance Consideration | Primary Objectives
Fixed | Base Salary | Fixed compensation component payable in cash, reviewed annually and subject to adjustment | Based on level of responsibility, experience, knowledge, and individual performance | Attract and retain
Variable | Short-Term Incentive Program | Short-term incentive payable based on performance against annually established goals | Measured by corporate and business unit performance oriented toward short-term financial goals | Promote achievement of short-term financial goals aligned with shareholder interests
Variable | Long-Term Incentive Program | Equity based awards consisting of restricted stock units and performance stock units | Creation of shareholder value and realization of medium and long-term financial and strategic goals | Create alignment with shareholder interests and promote achievement of longer-term financial and strategic objectives
Fixed | Retirement and Welfare Benefits | Retirement plans, health care and insurance benefits | Indirect - executive must remain employed to be eligible for retirement and welfare benefits | Attract and retain
Fixed | Perquisites - Flexible Cash Allowance and Executive Physicals | Quarterly fixed cash payment and executive physicals | Indirect - executive must remain employed to be eligible | Attract and retain

Role of the Compensation Committee

The Board-designed governance process expressly delegates to the Committee the responsibility to determine and approve Mr. Amato’s compensation, as well as to make all decisions regarding compensation for the other NEOs.

The Committee is composed entirely of independent directors, none of whom derives a personal benefit from the compensation decisions the Committee makes. Although the Committee does have responsibility for Board compensation matters, all such decisions are subject to full Board approval. The Board and Committee recognize the importance of executive compensation decisions to the management and shareholders of the Company.

The role of the Committee is to oversee compensation and benefit plans and policies, review and approve equity grants and administer share-based plans, and review and approve annually all compensation decisions relating to the Company’s directors (which decisions are subject to Board approval) and executive officers, including Mr. Amato and other NEOs. See “Summary of Key Compensation Decisions and Outcomes for 2017” for a summary of Committee decisions and outcomes during 2017.

TABLE OF CONTENTS

EXECUTIVE COMPENSATION — COMPENSATION DISCUSSION AND ANALYSIS

Input from Management

Certain senior executives provide information used by the Committee in the compensation decision-making process. Specifically, Mr. Amato provides input to the Committee regarding corporate and business unit performance goals and results. He also reviews with the Committee the performance of the executive officers who report directly to him, and makes recommendations to the Committee regarding their compensation. For 2017, Mr. Zalupski also provided input and analysis regarding financial and operating results.

The Committee carefully considers management’s input, but is not bound by their recommendations in making its final pay program decisions.

Independent Compensation Committee Consultant

Meridian Compensation Partners, LLC (“Meridian”), as the Committee’s external executive compensation consulting firm, is retained by and reports directly to the Committee.

Use of an outside consultant is an important component of our compensation setting process, as it enables the Committee to make informed decisions based on market data and best practices. Representatives from Meridian attend Committee meetings, meet with Committee members in executive session, and consult with the members as required to provide input with regard to CEO compensation based on the Committee’s assessment of performance.

Meridian has no affiliations with any of the NEOs or members of the Board other than in its role as an outside consultant. The Committee has been advised that Meridian has in place policies and procedures designed to prevent conflicts of interest and after applying such policies and procedures, determined that no conflict of interest existed in performing consulting services for the Company. Meridian does not provide any other services to the Company. All work performed by Meridian, whether with the Committee directly or with management at the direction of the Committee, requires pre-approval by the chair of the Committee. The Committee has assessed the independence of Meridian, as required under Nasdaq listing rules.

During 2017, Meridian provided quarterly updates regarding RTSR performance (relative to the S&P SmallCap 600 Capped Industrials Index), prepared estimated pay for performance modeling, provided input on our proxy statement and CD&A, provided an analysis of the historical performance of our peers, reviewed the design of incentives and other programs in place at our peers, and provided input on topics to be included in the Committee’s annual calendar.

Meridian also worked with the Committee to determine market competitive CEO compensation opportunities based on information gleaned from SEC filings of similarly-sized peer companies. Using this information, Meridian provided a set of recommended pay programs for Mr. Amato considered by the Committee.

The Role of Compensation Benchmarking Peer Group Assessment and Use of Survey Data

The Committee annually reviews a comparative peer group to ensure it remains reasonable for use for both pay level and pay design benchmarking purposes. The Committee takes into account changes in the size, scope, financial performance, ownership structure and business focus of the Company and the peer companies. The peer group is comprised of companies in the same or similar Global Industry Classification Standard categories as the Company (Industrial Machinery) that are roughly comparable to the Company in revenue. The yearly selection of peer companies is intended to help ensure that the data used for benchmarking executive compensation remains robust and flexible, so as to provide relevant, meaningful data as the Company and its market counterparts continue to grow and change.

In its annual review of the appropriateness of our peer group, the Committee updated the peer group to remove eight companies (specifically, Carlisle Companies Incorporated, Colfax Corporation, Crane Co., Greif, Inc., Silgan Holdings Inc., SPX Corporation, TransDigm Group Incorporated and Flowserve Corp.) and add six companies (specifically, CIRCOR International Inc., Myers Industries Inc., Nordson Corporation,

Analysis of Key 2017 Compensation Components and Decisions

The Committee made compensation decisions for 2017 using competitive market data provided by Meridian, benchmarking each of our NEOs’ base salary, STI and LTI against the market data. For this analysis, we consider target compensation that is within plus or minus 10% of the market median for each element of compensation as approximating the median (“Market Range”). Mr. Amato’s target total compensation was 14% below the market median, with his base salary and target STI 17% and 16% below the market median, respectively, and his target LTI within the Market Range. Mr. Zalupski’s target total compensation, base salary and STI were within the Market Range, with only his LTI target above the market median by 25%. Mr. Sherbin’s target total compensation was 11% above the market median, with his base salary and target STI within the Market Range, and his target LTI above the market median by 31%. These compensation levels established relative to market median generally reflect the Committee’s views on general business conditions, each NEO’s tenure in his role, the importance of placing higher value on performance-based compensation, and, with respect to Mr. Amato, the general terms negotiated and agreed upon when he joined the Company in July 2016.

Description of the material elements of our 2017 executive compensation program are provided in the following paragraphs.

2017 Base Salary

Base salaries for our NEOs are generally established based on the scope of their responsibilities, prior relevant experience and skills, and competitive market pay levels. The Committee believes that executive base salaries should generally be competitive with the size-adjusted median salaries for executives in comparable positions at the peer companies. We believe that providing competitive salaries is key to our ability to successfully attract and retain talented executives.

Each year, the Committee considers whether to grant merit increases and/or market-based adjustments to the Company’s NEOs. In doing so, it considers several factors such as individual responsibilities, Company and individual performance, experience, and alignment with market levels.

Based on the foregoing considerations, the Committee determined base pay adjustments were not necessary during 2017 and approved the following 2017 salaries for our NEOs:

NEO | Base Salary Rate as of January 1, 2017 | % Increase
Mr. Amato |  | $625,000 |  |  | — | %
Mr. Zalupski |  | $413,000 |  |  | — | %
Mr. Sherbin |  | $400,400 |  |  | — | %

EXECUTIVE COMPENSATION — COMPENSATION DISCUSSION AND ANALYSIS

2017 Short-Term Incentive Compensation Plan

The goal of the STI is to support our overall business objectives by aligning Company performance with the goals of shareholders and focusing attention on the key measures of success. The STI also plays a key role in ensuring that our annual cash compensation opportunities remain competitive. The STI awards for 2017 were provided under the Amended 2011 Plan, and for the NEOs other than Mr. Zalupski were initially funded for 2017 based on our achievement of a threshold level of $54.6 million in operating profit. For 2017, our actual recurring operating profit achievement was $106.3 million, and thus the 2017 STI awards for the NEOs other than Mr. Zalupski were initially funded at 200% of target opportunities, subject to reduction to final payout levels as explained further below.

Target Awards. Each of our NEOs had a target STI opportunity for the year that was expressed as a percentage of base salary. Target awards for 2017 are shown in the following chart:

NEO | Target STI Amount | Target Award as Percent of Salary
Mr. Amato |  | $625,000 |  |  | 100.0 | %
Mr. Zalupski |  | 268,450 |  |  | 65.0 | %
Mr. Sherbin |  | 240,240 |  |  | 60.0 | %

Depending on the performance results achieved, actual awards generally can vary as a percent of target from a threshold of 0% to a maximum of 200%. As part of the pay package agreed upon with Mr. Amato in 2016, Mr. Amato’s STI eligibility began in 2017.

Performance Measures

Each year, the Committee approves the specific performance metrics for that year’s program, and their relative weightings based on the importance of each applicable measure to the Company for the fiscal year. If the designated target level for each performance metric is attained, the STI award will pay out at 100% for the metric. The threshold is the lowest level of payout below which no payment is made for that specific component. If performance for a metric is between the identified threshold and the maximum, the actual payout is determined based on the achievement of milestones within a matrix, with the distance between the milestones pre-determined depending on the respective metric.

STI Performance Measures. The following underlying performance metrics were selected for the 2017 STI for the NEOs:

| • | Operating Profit - 70%. This measure rewards based on performance in recurring operating profit. Recurring operating profit means earnings before interest, taxes and other income/expense, and excludes certain non-recurring items (cash and non-cash) which may include, but are not limited to, income/expenses related to business restructuring, cost savings projects, debt refinancing, changes in accounting principles and asset impairments (collectively “Special Items”). This measure of profitability was selected because it is viewed as a leading indicator of our ability to effectively manage our costs throughout the business cycle.

| • | Cash Flow - 30%. Cash flow is the sum of recurring operating profit (defined above), adjusted (1) up or down for other income/expense, (2) up or down for changes in working capital, (3) upward for depreciation and amortization, (4) downward for capital expenditures, cash interest and cash taxes, and (5) up or down for the cash impact of any Special Items. Managing our cash generation capabilities and use of cash is an important measure of our ongoing liquidity and stability.

|  |  |  |  |  |  |  |  |  |  |  |  |  |  |  | Total |  | 124.2%

| (1) | Actual 2017 results were determined on a constant currency basis, using currency rates defined at the time the measures were approved. This is intended to evaluate the operating performance of each performance measure relative to targeted levels, and remove the positive or negative impact of changes in foreign currencies relative to the U.S. dollar during the year.

Award Determination and Payouts. In December 2017, based on its evaluation of 2017 performance, the Committee approved and authorized aggregate payouts of at least $4 million of the annual incentive awards for annual incentive award recipients, including the NEOs. In February 2018, the Committee determined and certified the degree to which the underlying STI goals for the prior year were achieved, which actual results are highlighted in the tables above. As a result, our NEOs earned the following STI payouts for 2017 performance:

NEO | Target Award as Percent of Base Salary | Target STI Amounts | STI Payout as % of Total Target Award | STI Earned and Paid in Cash(1)
Mr. Amato |  | 100.0 | % |  | $625,000 |  |  | 124.2 | % |  | $776,250 |
Mr. Zalupski |  | 65.0 | % |  | 268,450 |  |  | 124.2 | % |  | 333,415 |
Mr. Sherbin |  | 60.0 | % |  | 240,240 |  |  | 124.2 | % |  | 298,378 |

| (1) | Amounts earned by the NEOs are paid in cash.

Long-Term Incentive Program

Our long-term equity program is designed to reward the achievement of long-term business objectives that benefit our shareholders through stock price increases, thereby aligning the interests of our executives with those of our shareholders.

2017 Long-Term Incentive Awards

Under the 2017 Long-Term Incentive Award Program (“2017 LTI”), equity awards were granted to our NEOs and certain other eligible participants under the Amended 2011 Plan in order to promote the achievement of the Company’s strategic goals. The Committee granted RSUs and PSUs to our NEOs, to be settled in shares, with each vehicle accounting for 50% of the overall 2017 LTI target award value. As part of the pay package agreed upon with Mr. Amato in 2016, Mr. Amato’s annual LTI eligibility began in 2017. The Committee determined no adjustments to the target levels were necessary for the other NEOs from 2016.

The 2017 LTI award sizes as a percentage of each NEO’s base salary were as follows:

NEO | 2017 LTI Award as a % of Base Salary
Mr. Amato |  | 320% |
Mr. Zalupski |  | 170% |
Mr. Sherbin |  | 150% |

As discussed above, in determining the total value of the 2017 LTI award opportunity for each executive, the Committee reviewed survey data provided by Meridian regarding competitive award levels and considered each participant’s total compensation targets and level of responsibility within the organization.

TABLE OF CONTENTS

EXECUTIVE COMPENSATION — COMPENSATION DISCUSSION AND ANALYSIS

The approved target 2017 LTI grants for our NEOs are as follows:

Name | RSUs ($ Value) | 2017-2019 Cycle PSUs ($ Value)
Mr. Amato |  | $1,000,017 |  |  | $1,000,017 |
Mr. Zalupski |  | 350,014 |  |  | 350,014 |
Mr. Sherbin |  | 300,012 |  |  | 300,012 |

The dollar values listed in the above chart for the RSUs and PSUs were converted into a number of units based on the Company’s closing stock price on March 1, 2017 of $23.00. The 2017 RSUs generally vest in three equal installments on the first three anniversaries of the grant date of the award.

The 2017 PSU awards were designed to be earned generally based on the achievement of specific performance measures over a period of three calendar years. For the 2017-2019 cycle that began on January 1, 2017 and ends on December 31, 2019, 50% of the PSU award is earned based on the achievement of a specified RTSR percentile rank, and 50% is earned based on EPS CAGR performance, during the applicable performance period. The Committee approved RTSR as a performance measure and the use of the S&P SmallCap 600 Capped Industrials Index as the peer group for the performance measurement comparison. The Committee also approved EPS CAGR as a performance measure, which measure is the cumulative average growth rate of the diluted earnings per share from continuing operations as reported in the Company’s income statement within the applicable Form 10-Q and Form 10-K, plus or minus Special Items that may occur from time to time that the Committee believes should adjust the as-reported results for measurement of performance. The tables below detail the threshold, target and maximum performance target and opportunity for each metric. If, upon the conclusion of the performance period, RTSR or EPS CAGR falls between performance levels, straight-line mathematical interpolation will be used to determine the amount of the target PSUs (rounded down to the nearest whole number of PSUs) earned.

Performance Level | Relative Total Shareholder Return | RTSR PSUs Earned (50% of target)
Threshold | Ranked below or at 25th percentile | 0%
Above Threshold | Ranked at 35th percentile | 50%
Target | Ranked at 50th percentile | 100%

2015 PSU Grants Overview

The two 2015 PSU awards were designed to be earned based on the achievement of specific performance measures over periods of 28 months (the “2015-2017 Cycle”) and 16 months (the “2015-2016 Cycle”), respectively. For each of the 2015-2016 Cycle (which began on September 10, 2015 and ended on December 31, 2016) and the 2015-2017 Cycle (which began on September 10, 2015 and ended on December 31, 2017), the PSU award was earned based on the achievement of a specified RTSR percentile rank during the applicable performance period. The Committee approved RTSR as the performance measure and the use of the S&P SmallCap 600 Capped Industrials Index as the peer group for the performance measurement comparison, as outlined in the table below. If, upon the conclusion of the performance period, RTSR fell between performance levels, straight-line mathematical interpolation was used to determine the amount of the target PSUs (rounded down to the nearest whole number of PSUs) earned. As disclosed in last year’s proxy statement, the 2015-2016 Cycle PSU awards were earned at 121.13% and were settled in shares in early 2017.

2015 PSU Grant (2015 - 2017 Cycle) - Results

The following information is provided to describe the performance goals for the 2015-2017 Cycle PSU awards, the actual results relative to such performance goals, and how the Company calculated the payout amount for each 2015-2017 Cycle PSU award. As an initial matter, the 2015-2017 Cycle PSUs were designed for the NEOs other than Mr. Amato to be initially funded based on our achievement of a threshold level of $56.9 million in recurring operating profit. Our 2017 actual recurring operating profit achievement was $106.3 million, and thus the participating NEOs’ 2015-2017 Cycle PSU awards were initially funded at 200% of target opportunities, subject to reduction to final payout levels as explained further below.

The 2015-2017 Cycle PSU award opportunities provided to the NEOs other than Mr. Amato in 2015 represented performance based opportunities allocated 100% to RTSR results for a performance period running from September 10, 2015 to December 31, 2017. Overall achievement could vary from 0% of the target award to 200% of the target award (assuming maximum performance), with no award earned if performance fell below the threshold level.

The RTSR performance levels, achieved results, and resulting percentage of target award achieved for the 2015-2017 Cycle PSU awards are summarized in the following tables:

Performance Level | Relative Total Shareholder Return | Target PSUs Earned
Threshold | Ranked below or at 25th percentile | 0%
Above Threshold | Ranked at 35th percentile | 50%
Target | Ranked at 50th percentile | 100%
Intermediate | Ranked at 65th percentile | 150%
Maximum | Ranked at or above 80th percentile | 200%

TriMas TSR | RTSR | % of Target Earned
53.7% | 58.1 percentile | 126.9%

After performance results were determined, the earned 2015-2017 Cycle PSUs were settled in shares in early 2018.

Benefits and Retirement Programs

Consistent with our overall philosophy, the NEOs are eligible to participate during their service to the Company in benefit plans that are available to substantially all the Company’s U.S. employees. These programs include participation in our medical, dental, vision, group life, accidental death and dismemberment insurance programs, and the Company’s retirement program (comprised of a 401(k) savings plan). The TriMas Corporation Salaried Retirement Program (the “Plan”) was redesigned for 2017 by removing the non-elective and performance match contribution components, and increasing the

34 | I | 2018 Proxy Statement

TABLE OF CONTENTS

EXECUTIVE COMPENSATION — COMPENSATION DISCUSSION AND ANALYSIS

Company match contribution formula. The Plan is designed to reward continued employment with the Company and assist participants with financial preparation for retirement. Under the Plan, the Company provides a matching contribution of 75% of a participant’s contribution up to a maximum of 5% of the participant’s eligible compensation. Company matching contributions are immediately vested.

Executive Retirement Program

The Company’s executive retirement program provides senior managers with retirement benefits in addition to those provided under the Company’s qualified retirement plans. The Company offers these additional programs to enhance total executive pay so that it remains competitive in the market. Effective January 9, 2013, the Company began funding a Rabbi Trust for our obligations under this program. Trust assets are subject to the claims of the Company’s creditors in the event of bankruptcy.

Under the Supplemental Executive Retirement Plan (“SERP”), the Company makes a contribution to each participant’s account at the end of each quarter with the amount determined as a fixed percentage of the employee’s eligible compensation. The percentage is based on the employee’s age on the date of original participation in the plan (a 4.0% contribution for Messrs. Zalupski and Sherbin). Messrs. Zalupski and Sherbin’s contributions are 100% vested. Mr. Amato does not participate in the SERP.

The Compensation Limit Restoration Plan (“CLRP”) provides benefits to senior managers, including our NEOs, in the form of Company contributions which would have been payable under the Company match component of the Company’s tax-qualified retirement plan, but for tax code limits on the amount of pay that can be considered in a qualified plan. There are no employee contributions permitted under this plan. Company contributions under the CLRP vary as a percent of eligible compensation based on the employee’s elective deferrals into the qualified plan.

The executive retirement program also provides for an elective deferral compensation feature to supplement the existing executive retirement program. Employees eligible to receive SERP contributions may elect to defer up to 25% of base pay and up to 100% of bonus. This plan design component is intended to encourage the continued employment and diligent service of plan participants.

Perquisites

The Company maintains a Flexible Cash Allowance Policy. Under this program, participating executives receive a quarterly cash allowance in lieu of other Company-provided perquisites including supplemental universal life insurance, automobile allowance, private club membership and tax reimbursements. Eligibility for the cash allowances, and the amounts, are periodically reviewed by the Committee. Mr. Amato does not participate in this program. In February 2017, the Committee adjusted the quarterly cash allowance for the participating NEOs from $13,750 to $6,250 to be effective moving forward. Quarterly cash payments are made at the start of each fiscal quarter.

For the fiscal year 2017, the participating NEOs received the following cash allowances:

| • | Messrs. Zalupski and Sherbin - $32,500.

The Company also continues to make executive physical examinations available to its officers.

Change-of-Control and Severance-Based Compensation

The NEOs are covered by the Company’s Severance Policy (“Severance Policy”), the operation of which is described in further detail below under “Post-Employment Compensation.” In general, the Severance Policy provides that the Company will make severance payments to a covered executive if his or her employment is terminated under certain qualifying circumstances. The Severance Policy does not provide for any excise tax gross-ups; however, it provides for payments otherwise due upon a change-of-control to be reduced to ensure that none are subject to the golden parachute excise tax. The Severance Policy provides important financial protection to the named participants in exchange for non-compete and non-solicit covenants for the duration of an executive’s employment and a period following termination, and a requirement that an

2018 Proxy Statement | I | 35

TriMas Corporation

executive execute a release of claims in favor of the Company in order to receive any benefits under the Severance Policy. The Committee believes that offering this program is consistent with market practices, assures the Company can both attract and retain executive talent, and will assist with management stability and continuity in the face of a possible business combination.

The Committee periodically reviews the Severance Policy to evaluate both its effectiveness and competitiveness and to determine the value of potential payments.

Risk Mitigation in our Compensation Practices

The Committee focuses on risk mitigation in the design and implementation of the Company’s compensation practices. The Committee seeks to properly balance maximizing shareholder value creation, maintaining a strong pay for performance relationship, and providing for business risk mitigation. The Committee and management believe that the Company maintains appropriate compensation policies and practices, and that they do not give rise to risks that are reasonably likely to have a material adverse effect on the Company or encourage excessive risk taking. The Committee notes the employee compensation program includes a number of risk mitigation strategies, as detailed in the following chart:

COMPENSATION PRACTICE | RISK MITIGATION FACTORS
Short-Term Incentive Compensation | Multiple Performance Metrics. The short-term incentive plan uses multiple performance measures that encourage employees to focus on the overall strength of the business rather than a single financial measure.
Award Cap. STI awards payable to any individual are capped at 200% of the target award.
Clawback Provision. Our clawback policy allows us to recapture STI awards from certain executives, including NEOs, in certain situations, including restatement of financial results.
Management Processes. Board and management processes are in place to oversee risk associated with the STI plan, including, but not limited to, monthly business performance reviews by management and regular business performance reviews by the Board, Audit Committee, and our internal management disclosure committee.
Long-Term Incentive Compensation | Stock Ownership Guidelines. We have stock ownership requirements consistent with market norms for certain executives, including NEOs.
Award Cap. LTI awards payable to any individual are capped.
Retention of Shares. With respect to any certain executive, including NEOs, who has not met the ownership guidelines within the required period, the Committee may require the executive to retain all shares necessary to satisfy the guidelines, less an amount that may be relinquished for the exercise price and taxes.
Anti-Hedging/Pledging Restriction Policy. See discussion below regarding our anti-hedging and short sale/restricted pledging policies.
Clawback Provision. Our clawback policy permits the Committee to recoup or rescind equity awards to certain executives, including NEOs, under the LTI plan under certain situations, including restatement of financial results.

Accounting and Tax Effects

The impact of accounting treatment is considered in developing and implementing the Company’s compensation programs generally, including the accounting treatment as it applies to amounts awarded or paid to the Company’s executives.

The impact of federal tax laws on the Company’s compensation programs is also considered generally, including the deductibility of compensation paid to the NEOs, as regulated by Section 162(m) of the Code.

36 | I | 2018 Proxy Statement

TABLE OF CONTENTS

EXECUTIVE COMPENSATION — COMPENSATION DISCUSSION AND ANALYSIS

Under Section 162(m) of the Code, compensation paid to certain executive officers (and, beginning in 2018, certain former executive officers) in excess of $1 million is not tax deductible. Historically, compensation that qualifies as “performance-based compensation” under Section 162(m) of the Code could be excluded from this $1 million limit, but this exception has now been repealed, effective for taxable years beginning after December 31, 2017, unless certain transition relief for certain compensation arrangements in place as of November 2, 2017 is available. The Committee believes that the tax deduction limitation should not be permitted to compromise the Company’s ability to design and maintain executive compensation arrangements that will attract and retain the executive talent to compete successfully. Accordingly, achieving the desired flexibility in the design and delivery of compensation may result in compensation that in certain cases is not deductible for federal income tax purposes. Moreover, even if the Committee intended to grant compensation that qualifies as “performance-based compensation” for purposes of Section 162(m) of the Code, the Company cannot guarantee that such compensation will so qualify or ultimately is or will be deductible.

The Committee’s award of short- and long-term incentives granted in 2017 may require achievement of threshold performance metrics. The actual amount to be paid to an NEO in respect of such an incentive award may be determined in accordance with the negative discretion of the Committee, based on its assessment of overall performance results.

Likewise, the impact of Section 409A of the Code is taken into account, and the Company’s executive plans and programs are designed to comply with, or be exempt from, the requirements of that section so as to avoid possible adverse tax consequences that may result from noncompliance with Section 409A.

Stock Ownership Guidelines for Executives

To further align the interests of executives with those of shareholders, the Committee adopted stock ownership guidelines for certain executives, including the NEOs. The guidelines are expressed as a multiple of base salary, as set forth below:

Mr. Amato | 5x
Messrs. Zalupski and Sherbin | 3x

As of December 31, 2017, all of the continuing NEOs were in compliance with the stock ownership guidelines then applicable to them. New executives designated as participants will have five years from the time they are named to a qualifying position to meet the ownership guidelines. Adherence to these guidelines will be evaluated each year on the last trading day of the year, using the executive’s base salary and the value of the executive’s holdings and stock price on such day. Once an executive attains the required ownership level, the executive will not be considered noncompliant solely due to subsequent stock price declines as long as the executive continues to hold at least the number of shares the executive held as of the measurement date until the guideline ownership is again achieved.

Generally, Common Stock owned or beneficially owned by the executive, service-vesting restricted stock or restricted stock units, and vested, in-the-money stock options count toward satisfaction of the guidelines. Before satisfying the guidelines, an executive must hold at least 50% of shares acquired from equity compensation awards (generally, after recognition of shares or cash used for tax withholding or to pay the exercise price of an option).

The Committee has the discretion to consider non-compliance with the guidelines in determining whether or the extent to which future equity awards should be granted and may require all stock attained through Company grants be retained until the guidelines are satisfied.

Anti-Hedging, Short Sale and Pledging Policies

The Company’s anti-hedging policy prohibits our directors and executives, including NEOs, from purchasing any financial instrument that is designed to hedge or offset any decrease in the market value of the Common Stock, including prepaid variable forward contracts, equity swaps, collars, and exchange funds. The policy

2018 Proxy Statement | I | 37

TABLE OF CONTENTS

TriMas Corporation

also prohibits our directors and executives from engaging in short sales related to the Common Stock. Under the policy, directors and executives are prohibited from pledging shares of Common Stock. The prohibition on pledging implemented in 2018 modifies a policy adopted in 2014 that permitted pledging on a limited basis.

Recoupment Policy

In 2009, the Committee implemented a recoupment (or clawback) policy subjecting incentive compensation and grants under the Company’s equity compensation plans to executive officers and business unit presidents to potential recoupment. The Board has the authority to trigger recoupment in the event of a material financial restatement or manipulation of a financial measure on which compensation is based where the employee’s intentional misconduct contributed to the restatement or manipulation and, but for such misconduct, a lesser amount of compensation would have been paid. The Committee will reevaluate and, if necessary, revise the Company’s recoupment policy to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act once the rules implementing the recoupment requirements have been finalized by the SEC.

TriMas Corporation

Post-Employment Compensation

The Company maintains the revised Severance Policy, approved by the Committee in 2013. The Severance Policy applies to the Company’s executives identified by the Committee, including the NEOs while employed by the Company. The Severance Policy provides that the Company will make severance payments to an executive if his or her employment is terminated under certain circumstances. The Severance Policy includes an excise tax “cap” provision, which reduces the total amount of payments due under the Severance Policy so as to avoid the imposition of excise taxes and the resulting loss of tax deductions to the Company under Section 280G of the Code. The Severance Policy provides for non-compete and non-solicit covenants for the duration of an executive’s employment and a period following termination, and includes a requirement that an executive sign a release of claims in favor of the Company in order to receive any benefits under the Severance Policy.

If the Company terminates the employment of each of Mr. Amato, Mr. Zalupski or Mr. Sherbin for any reason other than for cause, disability, or death (cause and disability as defined in the Severance Policy), or if he terminates his employment for good reason (as defined in the Severance Policy), the Company will provide him with: (1) one year’s annual base salary (generally paid in equal installments over a year); (2) STI payment equal to one year’s payout at his target level in effect on the date of termination (generally paid in equal installments over two years); (3) accrued but unpaid base salary and unused vacation; (4) any STI payment that has been declared for him but not paid; (5) his pro-rated STI for the year of termination through the date of termination based on his target level and actual full-year performance; (6) his pro rata portion of time-based vesting equity awards and certain performance equity awards based on actual performance under all equity plans through the termination date; (7) executive level outplacement services for up to 12 months; and (8) continued medical benefits for up to 24 months following the termination date.

In the case of any participating executive’s voluntary termination or termination for cause, the Company pays the executive the accrued base salary through termination plus earned but unused vacation compensation (and, in the case of voluntary termination, any STI payment that has been declared for the executive but not paid). All other benefits cease as of the termination date. If an executive’s employment is terminated due to death, the Company pays the accrued but unpaid base salary as of the date of death, and accrued but unpaid STI compensation and fully vests all of the executive’s outstanding equity awards including performance-based equity awards at the target performance level. Other than continued participation in the Company’s medical benefit plan for the executive’s dependents for up to 36 months, all other benefits cease as of the date of the executive’s death. If an executive is terminated due to becoming disabled, the Company pays the executive earned but unpaid base salary and STI payments and fully vests all of the executive’s outstanding time-based equity awards and performance-based equity awards at the end of the performance period based on actual performance. All other benefits cease as of the date of such termination in accordance with the terms of such benefit plans.

In the case of a qualifying termination of Mr. Amato’s employment within two years of a change-of-control (as defined below), then, in place of any other severance payments or benefits, the Company will provide Mr. Amato with: (1) a payment equal to 24 months of his base salary rate in effect at the date of termination; (2) an STI payment equal to two years’ payout at his target level in effect at the date of termination; (3) any STI payment that has been declared for the executive but not paid; (4) his pro-rated STI payout for the year of termination through the date of termination based on his target level and actual full-year performance; (5) immediate vesting upon the termination date of all unvested and outstanding time-based vesting equity awards; (6) immediate vesting upon the termination date of all unvested and outstanding performance-based equity awards based on target performance; (7) executive level outplacement services for up to 12 months; and (8) continued medical benefits for up to 24 months following the termination date provided that the timing of the foregoing payments will be made in compliance with Code Section 409A.

In the case of a qualifying termination of each of Mr. Zalupski or Mr. Sherbin’s employment within two years of a change-of-control (as defined below), then, in place of any other severance payments or benefits, the Company will provide the executive with: (1) a payment equal to 36 months of his base salary rate in effect at the date of termination; (2) an STI payment equal to three years’ payout at his target level in effect at the

date of termination; (3) any STI payment that has been declared for the executive but not paid; (4) his pro-rated STI payout for the year of termination through the date of termination based on his target level and actual full-year performance; (5) immediate vesting upon the termination date of all unvested and outstanding time-based vesting equity awards; (6) immediate vesting upon the termination date of all unvested and outstanding performance-based equity awards based on target performance; (7) executive level outplacement services for up to 12 months; and (8) continued medical benefits for up to 36 months following the termination date provided that the timing of the foregoing payments will be made in compliance with Code Section 409A.

For purposes of the Severance Policy, “Change-of-Control” shall be deemed to have occurred upon the first of the following events to occur (as further described in the Severance Policy):

| 1. | a person is or becomes the beneficial owner of securities of the Company representing 35% or more of the combined voting power of the Company’s then outstanding securities (subject to certain exceptions);

| 2. | individuals who constitute the Board cease for any reason to constitute a majority of the number of directors then serving on the Board, unless their replacements are approved as described in the Severance Policy (subject to certain exceptions);

| 3. | the Company closes a merger, consolidation, wind-up, reorganization, or restructuring of the Company with or into any other entity, or a similar event or series of such events, resulting in a substantial change in the Company’s ownership or leadership, as further described in the Severance Policy, subject to certain exceptions; or

| 4. | the shareholders of the Company approve a plan of complete liquidation or dissolution of the Company or there is consummated an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets, as further described in the Severance Policy, and subject to certain exceptions.

Notwithstanding the foregoing, (1) a “Change-of-Control” shall not be deemed to have occurred by virtue of the consummation of any transaction or series of integrated transactions immediately following which the record holders of the common stock of the Company immediately prior to such transaction or series of transactions continue to have substantially the same proportionate ownership in an entity which owns all or substantially all of the assets of the Company immediately following such transaction or series of transactions and (2) if required to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, a “Change-of-Control” shall be deemed to have occurred only if the transaction or event qualifies as a Section 409A Change-of-Control.

In addition, the Severance Policy states that in return for these benefits, each executive covered under the Severance Policy must refrain from competing against the Company for a period following termination that corresponds to the duration of any severance payments the executive would be entitled to receive or 24 months if no severance payments are payable.

The Severance Policy may be modified by the Committee at any time, provided that the prior written consent of the executive is required if the modification adversely impacts the executive. Further, the Committee may amend or terminate the Severance Policy at any time upon 12 months’ written notice to any adversely affected executive.

TABLE OF CONTENTS

CEO Pay Ratio Disclosure

Mr. Amato, our CEO, had 2017 total compensation of $3,424,722, as reflected in the 2017 Summary Compensation Table. We estimate that the median of 2017 total compensation for all employees of the Company and its consolidated subsidiaries as of December 31, 2017 (the “Determination Date”), excluding our CEO, was $35,730, which amount comprises all applicable elements of compensation for 2017 in accordance with Item 402(c)(2)(x) of Regulation S-K (the “Median Annual Compensation”). The ratio of Mr. Amato’s 2017 total compensation to the Median Annual Compensation was approximately ninety-six to one. We note that, due to our permitted use of reasonable estimates and assumptions in preparing this pay ratio disclosure, the disclosure may involve a degree of imprecision, and thus this ratio disclosure is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K using the data and assumptions described below.

To identify the employee who received the Median Annual Compensation (the “Median Employee”), we measured annual base pay (consisting of regular base earnings and overtime) for the period beginning on January 1, 2017 and ending on December 31, 2017 for 4,013 employees, representing all full-time, part-time, seasonal, temporary and contract employees (whose compensation is determined by the Company) of the Company and our consolidated subsidiaries as of the Determination Date. In determining the Median Employee, we also annualized compensation for employees who worked less than all of 2017 (other than temporary employees) based on reasonable assumptions and estimates relating to our employee compensation program, including new hires.

ADDITIONAL INFORMATION

What is the purpose of the Annual Meeting?

At the Annual Meeting, holders of the Company’s Common Stock will act upon the matters outlined in the accompanying Notice of Annual Meeting, including: to elect three directors to serve until the annual meeting in 2021; to ratify the appointment of Deloitte as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018; to approve, on a non-binding advisory basis, the compensation paid to the Company’s NEOs; and to transact such other business as may properly come before the meeting. In addition, management will report on the performance of the Company and will respond to appropriate questions from shareholders.

Who is entitled to vote?

The Company’s Common Stock constitutes the Voting Stock of the Company. As of March 13, 2018 (the “Record Date”), there were no outstanding shares of preferred stock of the Company. Only record holders of Common Stock at the close of business on the Record Date are entitled to receive notice of the Annual Meeting and to vote those shares of Common Stock that they held on the Record Date. Each outstanding share of Common Stock is entitled to one vote on each matter to be voted upon at the Annual Meeting.

What constitutes a quorum?

For business to be conducted at the Annual Meeting, a quorum must be present. The presence at the Annual Meeting, in person or by proxy, of the holders of a majority of the shares of Common Stock issued and outstanding and entitled to vote on the Record Date will constitute a quorum for all purposes. As of the Record Date, 45,926,794 shares of Common Stock were issued and outstanding and entitled to vote. Broker non-votes and proxies marked with abstentions or instructions to withhold votes will be counted as present in determining whether there is a quorum.

What is the difference between holding shares as a shareholder of record and being a beneficial owner?

Shareholders of Record. If, at the close of business on the Record Date, your shares are registered directly in your name with the Company’s transfer agent, Computershare, you are considered the shareholder of record with respect to those shares, and these proxy materials (including a proxy card) are being sent directly to you by the Company. As a shareholder of record, you have the right to grant your voting proxy directly to the Company through the enclosed proxy card or to vote in person at the Annual Meeting.

Beneficial Owners. If, at the close of business on the Record Date, your shares were not issued directly in your name, but were held in a stock brokerage account or by a bank, trustee or other nominee, you are considered the beneficial owner of shares, and these proxy materials (including a voting instruction card) are being forwarded to you by your broker, trustee, bank or nominee who is considered the shareholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, trustee, bank, or nominee on how to vote the shares in your account and are also invited to attend the Annual Meeting. However, since you are not the shareholder of record, you may not vote these shares in person at the Annual Meeting unless you request and obtain a proxy from your broker, trustee, bank, or nominee. Your broker, trustee, bank or nominee has enclosed a voting instruction card for you to use in directing the broker, trustee, bank, or nominee on how to vote your shares.

How do I vote?

Shareholders of Record. If you complete and properly sign the accompanying proxy card and return it to the Company, it will be voted as you direct. You may also vote via telephone or internet (as indicated on your proxy card). If you attend the Annual Meeting, you may deliver your completed proxy card in person or vote by ballot.

ADDITIONAL INFORMATION

Beneficial Owners. If you complete and properly sign the accompanying voting instruction card and return it to your broker, trustee, bank or other nominee, it will be voted as you direct. You may also vote via telephone or internet (as indicated on your voting instruction card). If you want to vote your shares at the Annual Meeting, you must request and obtain a proxy from such broker, trustee, bank or other nominee confirming that you beneficially own such shares and giving you the power to vote such shares.

Can I change my vote after I return my proxy card or voting instruction card?

Shareholders of Record. You may change your vote at any time before the proxy is exercised by filing with the Corporate Secretary of the Company, at 38505 Woodward Avenue, Suite 200, Bloomfield Hills, Michigan 48304, either written notice revoking the proxy or a properly signed proxy that is dated later than the proxy card. If you attend the Annual Meeting, the individuals named as proxy holders in the enclosed proxy card will nevertheless have authority to vote your shares in accordance with your instructions on the proxy card unless you properly file such notice or new proxy.

Beneficial Owners. If you hold your shares through a bank, trustee, broker or other nominee, you should contact such person to submit new voting instructions prior to the time such voting instructions are exercised.

How will my shares be voted?

Shareholders of Record. All shares represented by the proxies mailed to shareholders will be voted at the Annual Meeting in accordance with instructions given by the shareholders. Where no instructions are given, the shares will be voted: (1) for the election of the Board of Directors’ nominees for three directors; (2) for the ratification of the appointment of Deloitte as the Company’s independent registered public accounting firm for the year ending December 31, 2018; and (3) for the approval, on a non-binding advisory basis, the compensation paid to the Company’s NEOs.

Beneficial Owners. The brokers, banks or nominees holding shares for beneficial owners must vote those shares as instructed, and if no instructions from the beneficial owner are received on a matter deemed to be non-routine, they may not vote the shares on that matter. Under applicable law, a broker, bank or nominee has the discretion to vote on routine matters, such as Proposal 2, but does not have discretion to vote with respect to non-routine matters, such as Proposals 1 or 3. Common Stock subject to broker non-votes will be considered present at the meeting for purposes of determining whether there is a quorum. Broker non-votes will have no effect in determining the outcome of the vote on Proposal 1 and will have the effect of a vote against Proposal 3. In order to avoid a broker non-vote of your shares on this proposal, you must send voting instructions to your bank, broker or nominee.

What are the Board’s recommendations?

The Board recommends a vote:

Proposal 1 — FOR the election of the nominated slate of directors.

Proposal 2 — FOR the ratification of the appointment of Deloitte as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018.

Proposal 3 — FOR the approval, on a non-binding advisory basis, of the compensation paid to the Company’s NEOs.

What vote is required to approve each item?

Proposal 1 - Election of Directors.

The three nominees who receive the most votes cast at the Annual Meeting will be elected as directors, provided a quorum of at least a majority of the outstanding shares of the Company’s Common Stock is represented at the meeting. However, we have adopted a majority voting policy that is applicable in

2018 Proxy Statement | I | 49

TriMas Corporation

uncontested director elections. This means that the plurality standard will determine whether a director nominee is elected, but our majority voting policy will further require that the number of votes cast “for” a director must exceed the number of votes “withheld” from that director or the director must submit his or her resignation. The Board, taking into account the recommendation of the Governance and Nominating Committee, would then determine whether to accept or reject the resignation. A proxy card marked “Withhold” or “For All Except” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated. Abstentions and broker non-votes will each be counted as present for purposes of determining the presence of a quorum, but will have no effect on the election of directors.

Proposal 2 - Ratification of the Appointment of Independent Registered Public Accounting Firm.

The affirmative vote of a majority of the shares of Common Stock present or represented by proxy at the Annual Meeting will be necessary to ratify the Audit Committee’s appointment of Deloitte as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018, provided that a quorum is present. Abstentions will have the same effect as a vote against the matter. Although shareholder ratification of the appointment is not required by law and is not binding on the Company, the Audit Committee will take the appointment under advisement if such appointment is not so ratified.

Proposal 3 - Approval, on a non-binding advisory basis, of the compensation paid to the Company’s NEOs.

The affirmative vote of a majority of the shares of Common Stock present or represented by proxy at the Annual Meeting will be necessary to approve the non-binding advisory resolution approving the compensation paid to the Company’s NEOs. While the Board of Directors intends to carefully consider the shareholder vote resulting from this proposal, the final vote is advisory in nature. Abstentions will have the same effect as a vote against the matter.

What will happen if other matters are raised at the meeting?

If any other matter is properly submitted to the shareholders at the Annual Meeting, its adoption will require the affirmative vote of a majority of the shares of Common Stock outstanding on the Record Date that is present or represented at the Annual Meeting. The Board does not propose to conduct any business at the Annual Meeting other than as stated above.

How do I find out the voting results?

Preliminary voting results will be announced at the Annual Meeting, and final voting results will be published by the Company in a Current Report on Form 8-K.

How may I obtain an additional copy of the proxy materials?

If you share an address with another shareholder, you may receive only one set of proxy materials unless you have provided contrary instructions. If you wish to receive a separate set of proxy materials now or in the future, please request the additional copy by contacting TriMas Corporation, Attention: Investor Relations, 38505 Woodward Avenue, Suite 200, Bloomfield Hills, Michigan 48304, Telephone 248-631-5450, or by email to generalcounsel@trimascorp.com. Additionally, if you have been receiving multiple sets of proxy materials and wish to receive only one set of proxy materials, please contact the Company’s Investor Relations department in the manner provided above.

What does it mean if I receive more than one proxy card or voting instruction card?

If you receive more than one proxy card or voting instruction card, it means that you have multiple accounts with banks, trustees, brokers, other nominees, and/or the Company’s transfer agent. Please sign and deliver

each proxy card and voting instruction card that you receive to ensure that all of your shares will be voted. We recommend that you contact your nominee and/or the Company’s transfer agent, as appropriate, to consolidate as many accounts as possible under the same name and address.

Who pays for the solicitation of proxies?

The accompanying proxy is being solicited by the Company’s Board. The Company will bear the cost of soliciting the proxies. Officers and other management employees of the Company will receive no additional compensation for the solicitation of proxies and may use mail, e-mail, personal interview, and/or telephone.

How can I access the Company’s proxy materials and Annual Report on Form 10-K?

The Financial Information subsection under “Investors” on the Company’s website, www.trimascorp.com, provides access, free of charge, to SEC reports as soon as reasonably practicable after the Company electronically files such reports with, or furnishes such reports to, the SEC, including proxy materials, Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to these reports. The Company has posted printable and searchable 2018 proxy materials to the Company’s website at http://ir.trimascorp.com. A copy of the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC, will be sent to any shareholder, without charge, upon written request sent to the Company’s executive offices at TriMas Corporation, Attention: Investor Relations, 38505 Woodward Avenue, Suite 200, Bloomfield Hills, Michigan 48304 or by email to generalcounsel@trimascorp.com.

Is a registered list of shareholders available?

The names of shareholders of record entitled to vote at the Annual Meeting will be available to shareholders entitled to vote at the meeting on Thursday, May 10, 2018 at the Company’s headquarters.

How and when may I submit a shareholder proposal or director nomination for the 2019 Annual Meeting?

For a shareholder proposal to be considered for inclusion in the Company’s proxy statement for the 2019 Annual Meeting, the Corporate Secretary must receive the written proposal at the Company’s principal executive offices no later than November 29, 2018.

For a shareholder proposal or director nomination that is intended to be considered at the 2019 Annual Meeting, but not included in the Company’s proxy statement, the shareholder must give timely notice to the Corporate Secretary not earlier than January 10, 2019 and not later than the close of business on February 9, 2019. Any shareholder proposal must set forth (1) a brief description of the business desired to be brought before the 2019 Annual Meeting and the reasons for conducting such business, (2) the name and address, as they appear on the Company’s books, of the shareholder proposing such business, (3) the number of shares of Common Stock that are beneficially owned by the shareholder, (4) any material interest of the shareholder in such business, and (5) any additional information that is required to be provided by the shareholder pursuant to Regulation 14A under the Exchange Act or the Company’s Third Amended and Restated Bylaws.
