PRELIMINARY PROXY STATEMENT SUBJECT TO COMPLETION

Dated March 15, 2024

[●], 2024

Dear Fellow Stockholders:

As chairman of MRC Global’s Board of Directors, I am proud of the Company’s strong commitment to its investors, customers, employees and sound governance. On behalf of the MRC Global Board of Directors, I thank you for your investment in our Company and your continued support.

We are pleased to invite you to the 2024 Annual Meeting of Stockholders that will be conducted virtually on [●], 2024, starting at [●] Houston, Texas time. Stockholders will be able to listen, vote and submit questions from any remote location with internet connectivity. A notice of the meeting and a Proxy Statement containing information about the matters to be acted upon are attached to this letter. Information on how to participate in this year’s virtual meeting can be found on page 1. Our Board of Directors recommends that you vote in accordance with our Board’s recommendations on all proposals using the WHITE proxy card.

In March of this year, we added David A. Hager to the Board as a new independent director. During his tenure as CEO and Executive Chairman of Devon Energy, Dave led the execution of a strategy that drove impressive returns for Devon’s shareholders. His breadth and depth of board and business experience, particularly in energy, will bring valuable perspectives to our board as MRC Global continues to invest in our growth drivers, serve our customer and drive to generate significant value for our shareholders. Also in March our Board determined to not re-nominate Barbara J. Duganier for re-election at the 2024 Annual Meeting of Stockholders as she had notified the Board of her desire to not stand for re-election. We want to thank Barbara for her many years of contribution to the Company and wish her the best in all of her future endeavors.

Engine Capital LP (together with its affiliates and related persons, “Engine Capital”) has notified the Company that it intends to nominate Bradley T. Favreau and Daniel B. Silvers (collectively, the “Engine Capital Nominees”) for election as directors at the Annual Meeting in opposition to the nominees recommended by our Board of Directors. As a result, you may receive solicitation materials from Engine Capital, including proxy statements and proxy cards, seeking your proxy to vote for Engine Capital’s nominees.

Our Board of Directors does not endorse the Engine Capital Nominees and unanimously recommends that you vote “FOR” the election of the eight nominees proposed by our Board:

and “FOR” the other proposals recommended by our Board using the WHITE proxy card. You may receive solicitation materials from Engine Capital, including proxy statements and [color?] proxy cards. MRC Global is not responsible for the accuracy or completeness of any information

provided by or relating to Engine Capital or its nominees in solicitation materials filed or disseminated by or on behalf of Engine Capital or any other statements Engine Capital may make.

Our Board strongly urges you to discard and NOT to vote using any [●] proxy card sent to you by Engine Capital. If you have already submitted a [●] proxy card, you can revoke the proxy and vote for our Board’s nominees and on the other matters to be voted on at the Annual Meeting by marking, signing and dating the enclosed WHITE proxy card and returning it in the enclosed postage-paid envelope or by voting via Internet by following the instructions on your WHITE proxy card, WHITE voting instruction form or notice. Only your latest validly executed proxy will count, and any proxy may be revoked at any time prior to its exercise at the Annual Meeting as described in the accompanying proxy statement.

PLEASE NOTE THAT THIS YEAR, YOUR WHITE PROXY CARD LOOKS DIFFERENT. RECENTLY ADOPTED NEW PROXY RULES REQUIRE THE COMPANY’S WHITE PROXY CARD TO LIST THE ENGINE CAPITAL NOMINEES IN ADDITION TO OUR BOARD’S NOMINEES. PLEASE MARK YOUR WHITE PROXY CARD CAREFULLY AND VOTE “FOR” ONLY THE EIGHT NOMINEES AND PROPOSALS THAT OUR BOARD RECOMMENDS.

Your vote is extremely important no matter how many shares you own. Whether or not you expect to attend the meeting, please promptly use your WHITE proxy card to vote by proxy over the Internet or by mail. If you have any questions or require any assistance with voting your shares, please call MRC Global’s proxy solicitor:

Changes to Board Composition

In March 2024, the Company added David A. Hager to the Board. Also in March 2024, the Board determined to not re-nominate Barbara J. Duganier for re-election at the 2024 Annual Meeting of Stockholders as she had notified the Board of her desire to not stand for re-election at the 2024 Annual Meeting of Stockholders. Effective as of the end of Ms. Duganier’s term of office, the Board has decreased the size of the Board from ten to nine directors.

If you plan to participate in the virtual 2024 Annual Meeting of Stockholders, please see the instructions on page 1 of the Proxy Statement.

TABLE OF CONTENTS

INSTRUCTIONS FOR THE VIRTUAL ANNUAL MEETING

Our 2024 Annual Meeting of Stockholders, or the Annual Meeting, will be a completely virtual meeting. There will be no physical meeting location.

How Can I Participate in the Virtual Annual Meeting?

The Annual Meeting will be held online via a live webcast at [●]. You are entitled to participate in the Annual Meeting only if you were a holder of Common or Preferred Stock as of the close of business on the Record Date, or your authorized representative or you hold a valid proxy for the Annual Meeting. Stockholders must pre-register to attend or vote by ballot at the Annual Meeting.

You may only participate in the virtual meeting by registering in advance at [●] prior to the deadline of [●] a.m. Central Time on [●], 2024. Please have your voting instruction form, proxy card or other communication containing your control number available and follow the instructions to complete your registration request.

If you are a beneficial holder, you must obtain a “legal proxy” from your broker, bank or other nominee if you wish to vote at the Annual Meeting. Upon completing registration, participants will receive further instructions via e-mail, including unique links that will allow them to access the meeting. Beneficial holders do not require a “legal proxy” to attend the meeting (but not vote at the meeting) and can do so by following the instructions above.

If you have any difficulty following the registration process, please email Morrow Sodali at MRC@info.morrowsodali.com.

Even if you plan to attend the virtual Annual Meeting, we recommend you also vote by proxy in advance of the Annual Meeting so that your vote will be counted if you later are unable or decide not to attend the virtual Annual Meeting.

Contested Election

Engine Capital has notified the Company that it intends to nominate Bradley T. Favreau and Daniel B. Silvers (collectively, the “Engine Capital Nominees”) for election as directors at the Annual Meeting in opposition to the nominees that our Board of Directors recommends. In accordance with our bylaws, all director nominees will be elected by a plurality of votes cast and the eight director nominees who receive the greatest number of votes will be elected to our Board at the Annual Meeting. Any shares not voted “FOR” a particular director nominee as a result of a “WITHHOLD” vote or a broker non-vote (as described below under “Voting Information”) will not be counted in that director nominee’s favor and will not otherwise affect the outcome of the election (except to the extent they otherwise reduce the number of shares voted “FOR” such director nominee).

All director nominees that our Board recommends have given their consent to be named as nominees for election and have indicated their intention to serve if they are elected. Our Board does not anticipate that any of our director nominees will be unable to serve as a director. If, at the time of the Annual Meeting, any nominee is unable to serve as a director, the discretionary authority provided in the enclosed proxy will be exercised to vote for a substitute candidate that our Board designates, unless the Board chooses to reduce its size.

We encourage you to vote by proxy using your WHITE proxy card or WHITE voting instruction form as promptly as possible, even if you plan to attend our Annual Meeting. If you have any questions about voting by proxy using your WHITE proxy card or WHITE voting instruction form, please contact Morrow Sodali LLC, our proxy solicitation firm, at MRC@info.morrowsodali.com or (203) 658-9400. Our Board unanimously recommends that you use the WHITE proxy card or WHITE voting instruction form to vote “FOR” only each of our Board’s eight director nominees.

As a result, you may receive solicitation materials from Engine Capital, including proxy statements and proxy cards, seeking your proxy to vote for the Engine Capital Nominees.

Our Board does NOT endorse any of the Engine Capital Nominees and unanimously recommends that you disregard any materials, including any [●] proxy card, that may be sent to you by Engine Capital. Importantly, voting on a [●] proxy card to “withhold” with respect to any of the Engine Capital Nominees is NOT the same as voting “FOR” our Board’s director nominees. This is because a vote on a [●] proxy card to “withhold” with respect to any of the Engine Capital Nominees will revoke any WHITE proxy card or WHITE voting instruction form you may have previously submitted. To support our Board’s director nominees, you should use the WHITE proxy card or WHITE voting instruction form to vote “FOR” only each of our Board’s eight director nominees.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES FROM GAAP

In this Proxy Statement, we present certain financial measures that deviate from measures calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). These non-GAAP measures are not necessarily better than the nearest GAAP measure but provide additional information as described below. For more complete information on the 2023 financial and operating performance of MRC Global Inc. (“MRC Global”, the “Company”, “we”, “us” or “our”), please review the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “Form 10-K”) that was filed with the U.S. Securities and Exchange Commission (the “SEC”) and can be found on the internet at www.viewourmaterial.com/mrc. This annual report provides a complete reconciliation of certain of the non-GAAP measures as described below.

Adjusted EBITDA. Adjusted EBITDA is a non-GAAP financial measure, and we define adjusted EBITDA as net income plus interest, income taxes, depreciation and amortization, amortization of intangibles and certain other expenses, including non-cash expenses (such as equity-based compensation, severance and restructuring, changes in the fair value of derivative instruments, long-lived asset impairments, including goodwill and intangible assets), inventory-related charges incremental to normal operations and plus or minus the impact of our last-in, first-out (“LIFO”) inventory costing methodology. We believe adjusted EBITDA provides investors a helpful measure for comparing our operating performance with the performance of other companies that may have different financing and capital structures or tax rates. We believe it is a useful indicator of our operating performance without regard to items, such as amortization of intangibles, which can vary substantially from company to company depending upon the nature and extent of acquisitions. Similarly, the impact of the LIFO inventory costing method can cause results to vary substantially from company to company depending upon whether they elect to utilize LIFO and depending upon which method they may elect. We believe that net income is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to adjusted EBITDA. See the following table for a detailed reconciliation of net income to adjusted EBITDA.

Adjusted Gross Profit. Adjusted gross profit is a non-GAAP financial measure. We define adjusted gross profit as sales, less cost of sales, plus depreciation and amortization, plus amortization of intangibles plus inventory-related charges incremental to normal operations, and plus or minus the impact of our LIFO inventory costing methodology. We present adjusted gross profit because we believe it is a useful indicator of our operating performance without regard to items, such as amortization of intangibles, which can vary substantially from company to company depending upon the nature and extent of acquisitions. Similarly, the impact of the LIFO inventory costing method can cause results to vary substantially from company to company depending upon whether they elect to utilize LIFO and depending upon which method they may elect. We use adjusted gross profit as a key performance indicator in managing our business. We believe that gross profit is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to adjusted gross profit. See the following table for a detailed reconciliation of gross profit to adjusted gross profit.

Net Debt. Net debt and related leverage metrics may be considered non-GAAP measures. We define net debt as total long-term debt, including the current portion, minus cash. We define our leverage ratio as net debt divided by adjusted EBITDA (as defined above). We believe net debt is an indicator of the extent to which the Company’s outstanding debt obligations could be satisfied by cash on hand and a useful metric for investors to evaluate the Company’s leverage position. We believe the leverage ratio is a commonly used metric that management and investors use to assess the borrowing capacity of the Company. We believe total long-term debt (including the current portion) is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to net debt.

The following table reconciles total long-term debt (including the current portion), as derived from our consolidated financial statements, with net debt (in millions) and shows the calculation of our leverage ratio:

RANCE Adjusted for LIFO. Return on average net capital employed (“RANCE”) adjusted for LIFO is a non-GAAP measure. We define RANCE adjusted for LIFO as RANCE, plus or minus the impact of the

benefit or expense of our LIFO accounting. We believe that RANCE, calculated in accordance with GAAP without the adjustment, is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to RANCE adjusted for LIFO. RANCE adjusted for LIFO is not necessarily a better measure of return. However, we believe that it provides a good measure of our return without the impact of our LIFO accounting for inventory. Inflationary and deflationary conditions, which are beyond management’s control, create swings in LIFO expense or benefit. The following table reconciles RANCE to RANCE adjusted for LIFO.

PROXY SUMMARY

This summary highlights information contained elsewhere in this Proxy Statement. This summary does not contain all of the information that you should consider, and you should read the entire Proxy Statement before voting.

(“MRC Global”, the “Company”, “we”, “us” or “our”), please review the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “Form 10-K”) that was filed with the SEC and can be found on the internet at www.viewourmaterial.com/mrc.

2023 Executive Compensation Highlights

“Pay for Performance” Executive Compensation Strategy

MRC Global’s executive compensation program is designed to attract, motivate and retain our executives, including our named executive officers (“NEOs”), who are critical to the Company’s long-term success. Our executive compensation strategy is “pay for performance” and is focused on:

We provide our executive officers with a compensation package that consists primarily of:

Our Compensation & Human Capital Committee, which is composed solely of independent directors, believes in a pay for performance philosophy. While our Compensation & Human Capital Committee sets target compensation for the executive officers each year based on market practices and internal considerations, the executive officers’ realized compensation is strongly dependent on the Company’s performance relative to pre-determined and measurable financial and safety metrics and stock price performance.

Target Compensation

The following illustration represents the elements of our 2023 compensation package at target to reflect the CEO’s compensation and an average for the other active NEOs.

The CEO’s Compensation at Risk has increased from 84% in 2022 to 85% in 2023, and the average Compensation at Risk for the other NEOs has increased from 66% to 71% from 2022 to 2023.

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING

Why am I receiving these materials?

We are furnishing this Proxy Statement to you as part of a solicitation by the Board of Directors of MRC Global Inc., a Delaware corporation, for use at our 2024 virtual Annual Meeting of Stockholders (the “Annual Meeting”) and at any reconvened meeting after an adjournment or postponement of the Annual Meeting. We will hold the Annual Meeting online only. There will be no physical meeting location. The Annual Meeting will be held on [●], 2024, at [●] a.m. Houston, Texas time. Please see Instructions for the virtual Annual Meeting on page 1.

We have two classes of stock: common stock, $.01 par value per share (“common stock”), and 6.5% Series A Convertible Perpetual Preferred Stock (“preferred stock”, and together with the common stock, “stock”). You are receiving these materials because, at the close of business on [●], 2024 (the “Record Date”), you owned shares of stock. All stockholders of record on the Record Date are entitled to attend and vote at the Annual Meeting. Each common stockholder will have one vote on each matter for every share of common stock owned on the Record Date. On the Record Date, we had a total of [●] shares of common stock, of which [●] shares are held in treasury, resulting in [●] shares of common stock entitled to vote at the meeting. Any shares held in our treasury on the Record Date are not considered outstanding and will not be voted or considered present at the meeting. On the Record Date, we had a total of [●] shares of preferred stock outstanding entitled to [●] votes at the Annual Meeting, which number is equal to the number of shares of common stock into which the shares of preferred stock could be converted on the Record Date, rounded to the nearest share. Holders of the common stock and the preferred stock vote (on an as-converted basis) together on all matters as a single class.

How is MRC Global distributing proxy materials? Is MRC Global using the SEC’s “Notice and Access” rule?

We expect our proxy materials including this Proxy Statement, our WHITE proxy card and our 2023 Annual Report (the “Annual Report”) (which includes the Form 10-K), to first be mailed on or about [●] and to first be made available to stockholders at that time. Copies of the Form 10-K, as well as other periodic filings by the Company with the SEC, are also available on our website at [●] by clicking on “INVESTOR” and “SEC Filings”. The information included in our website is not incorporated herein by reference.

MRC Global is not using the SEC’s “Notice and Access” rule with respect to this year’s Annual Meeting.

What information is contained in this Proxy Statement?

This Proxy Statement includes information about the nominees for director and other matters to be voted on at the Annual Meeting. It also:

What matters am I voting on, how may I vote on each matter and how does the Board recommend that I vote on each matter?

The following table sets forth each of the proposals you are being asked to vote on, how you may vote on each proposal and how the Board recommends that you vote on each proposal:

We are not aware of any matter to be presented at the Annual Meeting that is not included in this Proxy Statement. However, your proxy authorizes the person named on the proxy card to take action on additional matters that may properly arise. These individuals will exercise their best judgment to vote on any other matter, including a question of adjourning the Annual Meeting.

What is the difference between a stockholder of record and a stockholder who holds stock in street name?

If your shares are registered in your name with our transfer agent, Computershare Trust Company, N.A. (“Computershare”), you are a stockholder of record.

If you hold your shares with a broker or in an account at a bank, then you are a beneficial owner of shares held in “street name”. Your broker or bank is considered the stockholder of record for purposes of voting at the Annual Meeting. Your broker or bank should provide you with instructions for directing the broker or bank how to vote your shares.

How do I vote if I am a stockholder of record?

As a stockholder of record, you may vote your shares in any one of the following ways:

		Vote online at the Virtual Annual Meeting				Vote online at [●]
		If you receive a paper copy of the proxy materials, complete, sign, date and return the proxy card or voting instruction form

Unless you or your representative attend and vote online at the virtual Annual Meeting, for your vote to count the Company must receive your vote, either by internet, proxy card or voting instruction form by 11:59 p.m., Eastern Daylight Time on [●], 2024. Internet voting will close at 11:59 p.m., Eastern Daylight Time on [●], 2024.

If I hold shares in street name, does my broker need instructions to vote my shares?

Under rules of the New York Stock Exchange (the “NYSE”), if you hold shares of stock in street name and do not submit specific voting instructions to your brokers, banks or other nominees, they generally will have discretion to vote your shares on routine matters such as Proposal III but will not have the discretion to vote your shares on non-routine matters, such as Proposals I, II and IV. When the broker, bank or other nominee is unable to vote on a proposal because the proposal is not routine, and you do not provide any voting instructions, a broker non-vote occurs and, as a result, your shares will not be voted on these proposals.

Therefore:

How do I vote my shares?

If you are a stockholder of record, you may vote your shares by proxy without attending the Annual Meeting. We encourage stockholders to submit their proxies in advance of the Annual Meeting. You can ensure that your shares are voted by completing, signing and returning the WHITE proxy card or voting your shares over the Internet pursuant to the instructions provided on the WHITE proxy card. If you are voting over the Internet, you will need to provide the control number that is printed on the WHITE proxy card that you receive. Voting your shares by proxy by any of these methods will not affect your right to attend and vote at the Annual Meeting or by executing a proxy designating a representative to vote for you at the Annual Meeting.

You are urged to follow the instructions on your WHITE proxy card or voting instruction form to indicate how your vote is to be cast. Please see the Instructions for the virtual Annual Meeting on page 1 if you wish to attend the virtual meeting.

Pursuant to Section 212(c) of Delaware Law, stockholders may validly grant proxies over the internet. Your internet vote authorizes the proxies designated by the Company to vote your shares in the same manner as if you had returned a proxy card or voting instruction form. To vote over the internet, follow the instructions provided on your Notice. If you hold shares in street name, you are encouraged to contact your bank or broker to obtain and return the appropriate voting instruction form.

Other Candidates Nominated for Election as Directors at the Annual Meeting in Opposition to the Board’s Nominees

Engine Capital has notified the Company of its intent to nominate a slate of two alternative nominees for election as directors at the Annual Meeting in opposition to the nominees recommended by the Board. The Board does NOT endorse any of the Engine Capital Nominees and strongly urges you to discard and NOT sign or return any proxy card that may be sent to you by Engine Capital. The Board unanimously recommends that you vote “FOR ALL” the nominees proposed by the Board on the WHITE proxy card.

If you have previously submitted a proxy card sent to you by Engine Capital, you can revoke that proxy and vote for the Board’s recommended nominees and on the other matters to be voted on at the Annual Meeting by:

Only your latest dated proxy will count, and any proxy may be revoked at any time prior to its exercise at the Annual Meeting as described in this Proxy Statement. We are not responsible for the accuracy of any information that may be provided by or relating to Engine Capital or the Engine Capital Nominees contained in any solicitation materials that may be filed or disseminated by or on behalf of Engine Capital or any other statements Engine Capital may make.

It will NOT help elect the nominees recommended by the Board if you sign and return proxy cards sent by Engine Capital, even if you vote to “WITHHOLD” your vote with respect to their nominees using the Engine Capital proxy card. In fact, doing so will cancel any previous vote cast by you on the Company’s proxy card. The only way to support the Board’s recommended nominees is to vote “FOR” the Board’s recommended nominees by using the enclosed WHITE proxy card. Only the last proxy received will be counted.

Whether or not you plan to attend the Annual Meeting, it is important that your shares be represented and voted at the Annual Meeting. We encourage you to promptly vote in advance of the Annual Meeting by completing, signing and returning the WHITE proxy card or voting your shares over the Internet pursuant to the instructions provided on the WHITE proxy card. If you attend the Annual Meeting, you can vote even if you previously submitted your proxy.

If Engine Capital proceeds with its previously announced alternative director nominations, we may conduct multiple mailings of the Proxy Statement and the accompanying proxy materials prior to the Annual Meeting date so that stockholders have our latest proxy information and materials to vote. We will send you a new WHITE proxy card with each mailing, regardless of whether you have previously voted. The latest-dated proxy you submit will be counted, and, if you wish to vote as recommended by the Board, then you should only submit WHITE proxy cards.

What if I return my proxy card or vote by internet but do not specify how I want to vote?

If you are a stockholder of record and correctly sign, date and return your WHITE proxy card or complete the internet voting procedures, but do not specify how you want to vote your shares, we will vote them as follows:

What can I do if I change my mind after I vote my shares?

Attendance virtually in the virtual Annual Meeting will not in and of itself constitute revocation of a proxy. Any stockholder of record who authorizes his or her vote or by internet or executes and returns a proxy card may revoke the proxy before it is voted by:

For shares you hold in street name, you may change your vote by submitting new voting instructions to your broker, bank or other nominee or by obtaining a legal proxy from your broker, bank or other nominee giving you the right to vote your shares at the Annual M

eeting.

What shares are included on my proxy card?

You will receive one proxy card for all the shares of MRC Global that you hold as a stockholder of record (in certificate form or in book-entry form). If you hold your shares of MRC Global in street name, you will receive voting instructions for each account you have with a broker or bank.

How may I obtain instructions on how to attend the Annual Meeting online?

Please see Instructions for the virtual Annual Meeting on page 1. If you need assistance with these directions, please call us at 713-655-1005 or 877-294-7574 or write us at MRC Global Inc., 1301 McKinney Street, Suite 2300, Houston, Texas 77010, Attn: Corporate Secretary.

What is the quorum requirement for the Annual Meeting?

There must be a quorum to take action at the Annual Meeting (other than action to adjourn or postpone the Annual Meeting for lack of a quorum). A quorum will exist at the Annual Meeting if stockholders holding a majority of the voting powers of all of the shares entitled to vote at the Annual Meeting are present virtually or by proxy. Stockholders of record who return a proxy or vote virtually at the Annual Meeting will be considered part of the quorum. Abstentions and “broker non-votes” are counted as present and entitled to vote for purposes of determining a quorum.

What is the voting requirement to approve each of the proposals?

The following table sets forth the voting requirement with respect to each of the proposals:

Other matters that may properly come before the Annual Meeting may or may not require more than a majority vote under our bylaws, our Amended and Restated Certificate of Incorporation, the laws of Delaware or other applicable laws, depending on the nature of the matter.

Who will count the votes?

A representative of First Coast Results, Inc. will act as the inspector of elections and count the votes.

Where can I find the voting results of the Annual Meeting?

We will disclose the final voting results in a Form 8-K filed with the SEC within four business days after the Annual Meeting.

May I propose actions for consideration at the 2025 Annual Meeting of stockholders?

Yes. For your proposal to be considered for inclusion in our Proxy Statement for the 2025 annual meeting of stockholders, we must receive your written proposal no later than [●], 2024. If we change the date of the 2025 annual meeting of stockholders by more than 30 days from the anniversary of the date of this year’s Annual Meeting, then the deadline to submit proposals will be a reasonable time

before we begin to print and mail our proxy materials. Your proposal, including the manner in which you submit it, must comply with SEC regulations regarding stockholder proposals.

If you wish to raise a proposal (including a director nomination) from the floor during our 2025 annual meeting of stockholders, we must receive a written notice of the proposal no earlier than the close of business on January 7, 2025, and no later than the close of business on [●], 2025. If our first announcement of the date of the 2025 annual meeting of stockholders is less than 100 days prior to the meeting, then in accordance with the Bylaws, the Corporate Secretary of the Company must receive the notice by the 10^th day following the announcement. If the date of the 2025 annual meeting is more than 30 days before or more than 30 days after the anniversary of the date of this year’s Annual Meeting, you must deliver the notice not earlier than the close of business on the 120^th day prior to the date of the 2025 annual meeting and not later than the close of business on the later of the 90^th day prior to the date of the 2025 annual meeting. Your submission must contain the additional information that our bylaws require. Proposals should be addressed to our Corporate Secretary at 1301 McKinney Street, Suite 2300, Houston, Texas 77010.

Who is paying for this proxy solicitation?

Our Board is soliciting your proxy. We expect to solicit proxies in person, by telephone or by other electronic means. We have retained Morrow Sodali LLC, 430 Park Ave., 14th Floor, New York, NY 10022 to assist in this solicitation. We expect to pay Morrow Sodali LLC an estimated [●], plus expenses and disbursements. Morrow Sodali expects that approximately 45 of its employees will assist in the solicitation.

We will pay the expenses of this proxy solicitation, including the cost of preparing, printing and mailing the Notice, this Proxy Statement and related proxy materials. These expenses may include the charges and expenses of banks, brokerage firms and other custodians, nominees or fiduciaries for forwarding proxy materials to beneficial owners of MRC Global shares. Our aggregate expenses, including those of Morrow Sodali, other outside advisors, related to our solicitation of proxies in excess of expenses normally spent for an annual meeting of stockholders in which there is not a proxy contest are expected to be approximately $[●], of which approximately $[●] has been incurred as of the date of this Proxy Statement.

Are you “householding” for stockholders sharing the same address?

The SEC has adopted rules that allow a company to deliver a single set of proxy materials to an address shared by two or more of its stockholders.

BACKGROUND TO THE SOLICITATION

The summary below details the significant contacts between the Company and Engine Capital beginning on June 6, 2022 through the date of this proxy statement. This summary does not purport to catalogue every conversation of or between members of the Board, the Company’s management and the Company’s advisors, on the one hand, and representatives of Engine Capital and their advisors, on the other hand. Engine Capital LP is a stockholder which, together with its affiliates and related persons, purportedly was the owner of an aggregate of [3,866,886 shares of our common stock, or approximately 4.6% of the outstanding shares of our common stock, as of February 14, 2024].¹ In addition to the meetings described below, members of the Board received regular updates and met with management and the Company’s advisors regarding Engine Capital throughout the period leading up to the date of this proxy statement.

The Board and the Environmental, Social, Governance & Enterprise Risk Committee (the “ESG & Enterprise Risk Committee”) are committed to maintaining a Board with the skills, experience and capabilities desirable in light of the Company’s business and strategy, including customer or end market experience, leadership experience and experience in the areas of ESG and digital technology. The ESG & Enterprise Risk Committee annually assesses new candidates for the Board and welcomes suggestions regarding Board composition from the Company’s shareholders.

On June 6, 2022, Engine Capital introduced itself as a interested potential shareholder to a member of the Company’s investor relations team and had its first virtual meeting with members of the Company’s executive management team on August 18, 2022. From August 2022 through September 2023, the Company engaged periodically in constructive dialogue with Engine Capital with respect to the various questions relating to the strategic direction of the Company and other related topics.

On September 18, 2023, Rob Saltiel, the Company’s President and Chief Executive Officer, and Kelly Youngblood, the Company’s Executive Vice President and Chief Financial Officer, had a call with Arnaud Ajdler, a managing partner at Engine Capital, and Brad Favreau, a partner at Engine Capital. During this call, Messrs. Ajdler and Favreau stated that Engine Capital owned 2.5% of the Company’s common stock. They then previewed the contents of a letter Engine Capital intended to send to the Board and provided the Company with Engine Capital’s views as follows:

On September 18, 2023, Engine Capital e-mailed a letter to the Board setting forth Engine Capital’s 2.5% ownership of the Company’s outstanding common stock, its favorable views of the Company’s management and its belief that the Company should pursue strategic alternatives to increase the Company’s stock price (the “September 18, 2023 Letter”). 

On September 22, 2023, Engine Capital e-mailed the Company to state that it had increased its ownership of the Company’s outstanding common stock from 2.5% to closer to 4%.

On September 24, 2023, the Board met and, together with management and the Company’s advisors, discussed Engine Capital’s interactions with the Company, the September 18, 2023 Letter and response options.

On October 3, 2023, the Company e-mailed Engine Capital to thank Engine Capital for its continued interest and support and to advise that the Company had shared the letter with its Board and was in the process of reviewing Engine Capital’s suggestions and questions.

On October 4, 2023, Engine Capital replied by e-mail and requested that the Company implement its suggestions in the September 18, 2023 Letter “with a sense of urgency.”

On October 16, 2023, pre-market open, Bloomberg News published an article disclosing certain details contained in the September 18, 2023 Letter, including Engine Capital’s request that the Company explore a sale and that Engine Capital owned an approximately 4% stake of the Company.

On October 17, 2023, Engine Capital e-mailed the Company and wrote, with respect to the Bloomberg News article, that it was “unfortunate as we were hoping to keep [the September 18, 2023 Letter] private for now,” and requested a conversation with the Company about next steps.

On October 20, 2023, at the request and direction of the Board, representatives from J.P. Morgan (“JPM”), the Company’s financial advisor, telephonically met with Engine Capital in an effort to better understand Engine Capital’s thesis and intentions with the Company.

On October 27, 2023, Robert L. Wood, Chairman of the Board, and Leonard M. Anthony, a member of the Board, met virtually with Messrs. Ajdler and Favreau to discuss Engine Capital’s views on strategic alternatives available to the Company.

On October 31, 2023, Mr. Ajdler sent an e-mail to Mr. Wood and Mr. Anthony requesting that the Company:

On November 3, 2023, the Board met and, together with management and the Company’s advisors, discussed Engine Capital’s recent communications. Separately, on November 3, 2023, upon the recommendation of the ESG & Enterprise Risk Committee, as part of its annual governance review the Board approved and adopted changes to the Company’s bylaws and Corporate Governance Guidelines focused on mechanics related to universal proxy changes and other standard market practices for director nominations.

On November 8, 2023, members of the Company’s management conducted its third-quarter earnings call, during which, among other things, they spoke about the Company’s plans for growth in the future, including possible M&A to grow the Company.

On November 9, 2023, Mr. Ajdler e-mailed Messrs. Saltiel, Youngblood, Wood and Anthony with Engine Capital’s feedback on the earnings call. In his e-mail, Mr. Ajdler stated his belief that the Company should be taken private and should not attempt to grow through acquisitions. Later that day, Mr. Youngblood and a member of the Company’s investor relations team, met telephonically with Engine Capital to discuss the earnings call, as well Engine Capital’s thesis and its request to add an individual selected by Engine Capital to the Board.

On November 12, 2023, Mr. Wood responded to Mr. Ajdler’s October 31, 2023 e-mail and advised that the Board is open to receive names of qualified directors with needed skill sets, including skill sets in technology (enterprise systems technology) and cyber security.

On November 14, 2023, Mr. Ajdler e-mailed Mr. Wood, copying certain other members of the Board, and saying that Engine Capital wants a director with “an investor mindset in the boardroom,” because it will be “important in the context of evaluating a potential sale” and that Engine Capital, as a “large shareholder,” would like to have “a seat at the table.”

On November 17, 2023, at the request and direction of the Board, Daniel Churay, General Counsel and Corporate Secretary of the Company, e-mailed Engine Capital to request the name of its proposed nominee to the Board.

On November 29, 2023, Engine Capital e-mailed Mr. Churay and advised that Engine Capital proposed that Mr. Favreau be added to the Board.

Between December 5, 2023 and December 13, 2023, the Company exchanged e-mails and coordinated with Engine Capital to schedule an interview of Mr. Favreau with members of the ESG & Enterprise Risk Committee.

On December 15, 2023, the Board met and, among other things, Mr. Churay provided the Board with an update on discussions with Engine Capital and noted that an interview of Mr. Favreau would be held in January to discuss his candidacy. Further, it was noted that the ESG & Enterprise Risk Committee was scheduled to meet on December 18, 2023 to discuss the current composition, profile and skills of the Board to provide a view as to the qualifications and profile of a new director that the Board might consider, if any.

On December 18, 2023, the ESG & Enterprise Risk Committee met and, among other things, discussed the current composition, profile and skills of the Board, to identify the current needs of the Board.

On January 8, 2024, Mr. Favreau met in person at the Company’s corporate headquarters with each of Barbara J. Duganier and Deborah G. Adams, members of the ESG & Enterprise Risk Committee, as well as with Messrs. Saitel, Youngblood and Churay.

On January 23, 2024, in line with the Company’s standard process, Mr. Churay sent to Mr. Favreau a director and officer questionnaire and asked that it be completed by Mr. Favreau in connection with the ESG & Enterprise Risk Committee’s evaluation of him as a Board candidate.

On January 25, 2024, Messrs. Ajdler and Favreau met virtually with Messrs. Wood, Anthony, Churay and Youngblood and Ms. Duganier, and reviewed written materials to reiterate Engine Capital’s position that the Company should consider a sale of the Company or, alternatively, consider stock repurchases and add Mr. Favreau to the Board. The Board met the same day to review and discuss Engine Capital’s written presentation and the request to add Mr. Favreau to the Board.

On January 25, 2024, the Board met and, among other things, discussed the skill sets and qualifications of the current members of the Board of directors and of Mr. Favreau. Additionally, the ESG & Enterprise Risk Committee authorized the retention of the Heidrick & Struggles (“Heidrick”) to assist the committee to identify qualified director candidates.

On February 2, 2024, Engine Capital delivered a written notice formally nominating three individuals, Marjorie L. Bowen, Bradley T. Favreau, and Daniel B. Silvers, as stockholder nominees to be elected to the Board at the Annual Meeting. On the same day, Mr. Ajdler e-mailed Messrs. Saltiel, Youngblood, Anthony and Wood to apprise them of Engine Capital’s nominations, its reasons for making the nominations and its desire to keep the nominations private.

On February 7, 2024, the Board met and discussed, among other things, the date of the Annual Meeting and proposed slate of directors to be elected at the meeting.

During the month of February 2024, at the request and direction of the Board and the ESG & Enterprise Risk Committee, Mr. Churay coordinated interviews of 10 potential director candidates, including nominees identified by Heidrick and Engine Capital’s nominees.

On February 19, 2024, the Board met and received a report from members of the ESG & Enterprise Risk Committee relating to director candidate interviews that had been conducted through that date and to review biographical background, including skill sets and experience of select candidates.

On February 23, 2024, Mr. Churay requested that Engine Capital provide contact information for each of Ms. Bowen and Mr. Silvers to schedule interviews with members of the ESG & Enterprise Risk Committee. On February 24, 2024, Mr. Ajdler replied to the Company’s e-mail and declined to provide the requested contact information unless and until the Company and Engine Capital discuss and agree upon terms of a potential settlement agreement.

On February 26, 2024, at the request and direction of the ESG & Enterprise Risk Committee, Mr. Churay e-mailed Engine Capital to again request contact information for each of Ms. Bowen and Mr. Silvers and to apprise Engine Capital that, consistent with the Board’s past practice, prior to appointment or nomination of any new director, interviews with nominees need to be conducted.

On February 26, 2024, Mr. Jadin and Ms. Duganier, members of the ESG & Enterprise Risk Committee, and Mr. Wood met virtually with David A. Hager, a board candidate that Heidrick identified to discuss his background and qualifications to serve on the Board.

On February 27, 2024, Mr. Ajdler responded via e-mail that Engine Capital needed to understand the context of these interviews and asked the Company to acknowledge that the interviews of its proposed candidates would be conducted in good faith.

On February 28, 2024, Messrs. Wood, and Anthony met virtually with Messrs. Arnaud and Favreau. Mr. Wood apprised Engine Capital of the Company’s process for identifying new directors to the Board and noted that the Board has a responsibility to its shareholders to have all board candidates, including Engine Capital’s nominees, undergo substantially similar vetting processes. Mr. Arnaud responded that Engine Capital “wants and earned representation” on the Board.

On February 28, 2024, Dr. McEntee met virtually with Mr. Hager to discuss his background and qualifications to serve on the Board.

On February 29, 2024, Mr. Arnaud e-mailed Mr. Churay the contact information for Ms. Bowen and Mr. Silvers, and Mr. Churay organized interviews with each of them.

On March 1, 2024, Ms. Adams and Mr. Anthony met virtually with Mr. Hager to discuss his background and qualifications to serve on the Board.

On March 4, 2024, Barbara Duganier, Deborah Adams and George Damiris, members of the ESG & Enterprise Risk Committee along with Mr. Saltiel met virtually with Ms. Bowen to discuss her background and qualifications to serve on the Board.

Also, on March 4, 2024, Ms. Adams and Messrs. Damiris and Saltiel, met virtually with Mr. Silvers to discuss his background and qualifications to serve on the Board.

On each of March 4, 2024 and March 6, 2024, the Board met, together with members of management and the Company’s advisor, and discussed, among other things, the interviews conducted by members of the ESG & Enterprise Risk Committee and the skills sets and experience of select candidates, including those of Ms. Bowers, Mr. Favreau, Mr. Silvers and Mr. Hager, as well as Board diversity.

On March 11, 2024, the ESG & Enterprise Risk Committee and the Board, together with members of management and the Company’s advisors, met to consider and approve a proposed slate of directors for election at the Annual Meeting, as well as consider and approve a proposal to increase the size of the Board. At the meeting, the Board determined to increase the size of the Board from nine to 10 directors and to appoint David A. Hager as a member of the Board as of March 11, 2024. In deciding to appoint Mr. Hager, the Board considered Mr. Hager’s breadth and depth of board and business experience, his transactional experience, his financial literacy, his knowledge of upstream and midstream markets and the North America energy business and his independence per the rules and regulations of the New York Stock Exchange and the Securities and Exchange Commission (“SEC”). In addition, at the meeting Barbara J. Duganier announced her desire to not run for re-election at the

Annual Meeting, and the Board determined to recommend the following persons as the slate of directors nominated to be elected at the Annual Meeting: Ms. Adams, Dr. McEntee and Messrs. Anthony, Damaris, Hager, Jadin, Saltiel and Wood.

On March 11, 2024, Messrs. Wood and Anthony met virtually with Messrs. Ajdler and Favreau to notify them that the Board had determined to not recommend any of Engine Capital’s nominees to the slate of directors for election at the Company’s 2024 annual meeting of stockholders.

On March 14, 2024, Engine Capital delivered a written notice formally withdrawing their nomination of Marjorie L. Bowen as a stockholder nominee. The letter stated that Engine Capital’s nomination of Bradley T. Favreau and Daniel B. Silvers remained in full force and effect.

On March 15, 2022, the Company filed this preliminary proxy statement with the SEC.

SECURITY OWNERSHIP

Directors and Executive Officers

The following table shows, as of February 15, 2024, the number of shares of our common stock that each of our directors, each of our named executive officers (NEOs) and all of our executive officers and directors as a group beneficially own.

The rules of the SEC generally determine beneficial ownership, which generally includes voting or investment power with respect to securities. Unless indicated below, to our knowledge, the persons and entities that the table names have sole voting and sole investment power with respect to all shares beneficially owned, subject to community property laws where applicable. Shares of common stock subject to options that are currently exercisable or exercisable within 60 days of February 15, 2024, are deemed to be outstanding and to be beneficially owned by the person holding the options for the purpose of computing the percentage ownership of that person but are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unvested restricted stock units (RSUs) and performance share units (PSUs) are not included to the extent they will not definitively vest within 60 days of February 15, 2024. Except as otherwise indicated, the business address for each of our beneficial owners is c/o MRC Global Inc., 1301 McKinney Street, Suite 2300, Houston, Texas 77010.

As of February 15, 2024, the Company’s directors and executive officers beneficially owned 20.9% of our outstanding common stock (assuming conversion of all preferred stock to common stock). The percentage beneficially owned was calculated based on 85,232,679 shares of common stock and preferred stock convertible into 20,302,009 shares of common stock for a total of 105,534,688 shares outstanding on February 15, 2024.

Certain Beneficial Owners

The following table sets forth information regarding persons or groups known to the Company to be beneficial owners of more than 5% of our outstanding preferred stock or common stock as of February 15, 2024, including the business address of each.

Preferred Stock Issuance

In June 2015, we filed with the Secretary of State of the State of Delaware a Certificate of Designations, Preferences, Rights and Limitations of Series A Convertible Perpetual Preferred Stock (the “Certificate of Designations”) creating the Series A Convertible Perpetual Preferred Stock, par value $0.01 per share (the “preferred stock”), and establishing the designations, preferences, and other rights of the preferred stock. On June 10, 2015, we issued 363,000 shares of preferred stock and received gross proceeds of $363 million. In connection with the issuance, we entered into a shareholders’ agreement (the “Shareholders’ Agreement”) with Mario Investments LLC, the initial holder of the preferred stock (the “Initial Holder”). The following description is qualified in its entirety by reference to the full text of the Certificate of Designations and the Shareholders’ Agreement, each of which were filed as exhibits to our Current Report on Form 8-K, which was filed with the SEC on June 11, 2015. Capitalized terms used in this “Preferred Stock Issuance” description that are not defined in this Proxy Statement shall have the terms that the Certificate of Designations assigns to those terms.

Voting and Other Rights

The preferred stock ranks senior to our common stock with respect to dividend rights and rights on liquidation, winding-up and dissolution. The preferred stock has a stated value of $1,000 per share, and holders of the preferred stock are entitled to cumulative dividends payable quarterly in cash at a rate of 6.50% per annum.

The preferred stock does not create a dual class voting structure as it is does not constitute a second class of common stock with special voting rights. Holders of the preferred stock are entitled to vote together with the holders of the common stock as a single class, in each case, on an as-converted basis, except in rare instances when the law requires a separate class vote of the common stockholders. The preferred stockholders also have certain rights regarding the issuance of stock that is Parity Stock or Senior Stock (as each of those terms are defined in the Certificate of Designations). A vote of two-thirds of the preferred stock is required to:

or, in either case, certain additional requirements are not met.

Pursuant to the Shareholders’ Agreement, the Initial Holder and certain related parties if the preferred stock is transferred to those parties (collectively, the “Original Holder’s Group”) are entitled to vote their shares in their discretion. Holders of the preferred stock have certain limited special approval rights, including with respect to the issuance of pari passu or senior equity securities of the Company.

Lapse of Certain Voting Requirements

Prior to June 10, 2020, the Original Holder’s Group agreed to vote their shares in favor of director nominees that the Board nominates. This provision has lapsed, and the Original Holder’s Group is no longer required to vote their shares in favor of director nominees that the Board nominates.

Sunset Provisions

The preferred stock is convertible at the option of the holders into shares of common stock at an initial conversion rate of 55.9284 shares of common stock for each share of preferred stock, which represents an initial conversion price of $17.88 per share of common stock, subject to adjustment. The Company currently has the option to redeem, in whole but not in part, all of the outstanding shares of preferred stock at par value, subject to certain redemption price adjustments. We may elect to convert the preferred stock, in whole but not in part, into the relevant number of shares of common stock if the last reported sale price of the common stock has been at least 150% of the conversion price then in effect for a specified period. The conversion rate is subject to customary anti-dilution and other adjustments.

Fundamental Change

If a Fundamental Change occurs, each holder of the preferred stock has the right, at the holder’s option, to require the Company to repurchase all or part of the holder’s shares of preferred stock for cash. Among other things, as described as follows, an all-cash acquisition of the Company would constitute a Fundamental Change, but a stock-for-stock merger of the Company would not so long as the shares received in exchange for Company common stock were quoted or listed on a major U.S. stock market. A “Fundamental Change” occurs when:

provided, that any transaction described in clause (B) above in which the holders of all classes of the Company’s Common Equity immediately prior to such transaction(s) own, directly or indirectly, more than 50% of all classes of Common Equity of the continuing or surviving corporation or transferee or the parent thereof immediately after such transaction(s) in substantially the same proportions as such ownership immediately prior to such transaction(s) will not be a Fundamental Change;

provided, that:

Board Representation Rights

Pursuant to the Shareholders’ Agreement, for so long as the Original Holder’s Group maintained at least 33% of their original investment (whether in preferred stock or shares of common stock issued upon conversion of the preferred stock), the Original Holder’s Group has the right to appoint a single representative, in a non-voting observer capacity, to attend all meetings of the Board, subject to certain exceptions.

Pursuant to the Certificate of Designations and the Shareholders’ Agreement, on June 10, 2018, the Original Holder’s Group had the right to designate one person to serve as a director on the Board if the Original Holder’s Group maintained at least 33% of their original investment and shares of the preferred stock remained outstanding. The Original Holder’s Group met such requirement, and the Company was required to increase the size of the Board to accommodate the appointment of Henry Cornell, as a director designated by the Original Holder’s Group on June 10, 2018. The holders of the preferred stock also have certain Board representation rights if dividends payable on the preferred stock are in arrears for six or more quarterly periods, but in no event may the holders of the preferred stock appoint more than two directors. Also, pursuant to the Shareholders’ Agreement, if no shares of the preferred stock remain outstanding but the Original Holder’s Group maintains at least 33% of their original investment through their shares of common stock received upon conversion of the preferred stock, the Original Holder’s Group may designate one nominee to serve as a director on the Board (the “Investor Designee”), subject to the Investor Designee’s satisfaction of all applicable requirements regarding service as a director of the Company under applicable law, regulation or stock exchange rules and such other criteria and qualifications the Company maintained that is applicable to all directors as of the date of the issuance of the preferred stock. The Company is required to increase the size of the Board by one director and fill the vacancy with the Investor Designee. Thereafter, the Company is required to nominate the Investor Designee for election by the Company’s stockholders and recommend that the Company’s stockholders vote in favor of the election of the Investor Designee.

If for any reason the director that the Original Holder’s Group appointed or designated is no longer serving as a director, the Original Holder’s Group may appoint or designate a new person to fill the vacancy. At such time as the Original Holder’s Group owns less than 33% of their original investment, pursuant to the Shareholders’ Agreement, the rights of the Original Holder’s Group terminate, and the Investor Designee must resign.

Certain Other Provisions

Pursuant to the Shareholders’ Agreement, the Original Holder’s Group has certain registration rights, including customary demand and piggyback registration rights in respect of the shares of preferred stock and any shares of common stock issued upon conversion of the preferred stock.

Pursuant to the Shareholders’ Agreement, for so long as the Original Holder’s Group maintains at least 33% of their original investment (whether in preferred stock or shares of common stock issued upon conversion of the preferred stock), the Company is required to, prior to the issuance of equity securities to a third party (subject to certain exceptions), offer the Original Holder’s Group the right to acquire its pro rata portion of such equity securities.

MRC Global Inc. may not enter into any new, or amend, or modify any existing agreement or arrangement that by its terms restricts, limits, prohibits or prevents the MRC Global Inc. from paying dividends on the Preferred Stock, redeeming or repurchasing the Preferred Stock or effecting the conversion of the Preferred Stock. Any such agreement, amendment or modification would require the consent of the holder of the Preferred Stock.

PROPOSAL I: ELECTION OF DIRECTORS

The directors of the Company are elected by the stockholders annually. As of the date of this proxy statement, the Board consists of ten members. Eight directors will stand for re-election and be elected by holders of our common stock and preferred stock, voting together, and the holder of the Company’s preferred stock has designated and will designate the other director.

Each director’s term of office expires when his or her successor is elected and qualified at the Annual Meeting. At the Annual Meeting, our stockholders will elect the eight directors named below to hold office until the 2025 annual meeting of stockholders (the “2025 Annual Meeting of Stockholders”), or until their successors are elected and qualified, or their earlier retirement, removal or death. Each director has served continuously since the date of his or her appointment. All nominees have consented to being named in this Proxy Statement and to serve if elected. If any nominee should be unable or unwilling to stand for election as a director, it is intended that the common stock represented by proxies will be voted for the election of a substitute director that the Board may nominate.

As set forth in the Company’s Certificate of Designations and the Shareholders’ Agreement, the Original Holder’s Group has the right to designate one person to serve as a director on the Board. The Original Holder’s Group designated Henry Cornell to serve as a director on the Board effective June 10, 2018. The Original Holder’s Group, as holders of the preferred stock, have indicated to the Company their intent to continue to designate Mr. Cornell. Because the holders of the preferred stock designate Mr. Cornell, the holders of our common stock will not vote to elect him.

As described under “Corporate Governance Matters—Process for Identifying and Adding New Directors” below, the Board seeks a diverse group of candidates who possess the background, skills and expertise to make a significant contribution to the Board and the Company. The structure and composition of the Board are intended to leverage diverse perspectives of the Board members and promote effective oversight.

As described under “Background to the Solicitation” above, based upon the Company’s criteria for nominations of directors to the Board and the unanimous recommendation of the ESG & Enterprise Risk Committee, the Board unanimously determined to nominate Deborah G. Adams, Leonard M. Anthony, George J. Damiris, David A. Hager, Ronald L. Jadin, Dr. Anne McEntee, Robert J. Saltiel, Jr. and Robert L. Wood to serve until the 2025 Annual Meeting. See the section of this proxy statement titled “—Certain Information Regarding Nominees” below for more information about the skills, qualifications, attributes and experiences upon which the Board based its determination that its nominees should serve as directors.

As described previously, Engine Capital has notified the Company that it intends to nominate Bradley T. Favreau and Daniel B. Silvers (collectively, the “Engine Capital Nominees”) for election as directors at the Annual Meeting in opposition to the nominees recommended by the Board.

The Board does not endorse the Engine Capital Nominees, and unanimously recommends that you use the WHITE proxy card to vote “FOR” ONLY the election of the eight nominees proposed by the Board of Directors:

The Board strongly urges you to discard and NOT to vote using any [●] proxy card that may be sent to you by Engine Capital. If you have already voted using a [●] proxy card sent to you by Engine Capital, you have every right to change your vote and we strongly urge you to revoke that proxy by using the

WHITE proxy card to vote in favor of ONLY the eight nominees that the Board recommends—by internet or by signing, dating and returning the enclosed WHITE proxy card in the postage-paid envelope provided. Only the latest validly executed proxy that you submit will be counted—any proxy may be revoked at any time prior to its exercise at the Annual Meeting. If you have any questions or require any assistance with voting your shares, please contact Morrow Sodali LLC, our proxy solicitation firm, at (203) 658-9400.

If Engine Capital withdraws its nominees, abandons its solicitation or fails to comply with the universal proxy rules after a shareholder has already granted proxy authority, shareholders can still sign and date a later submitted WHITE proxy card.

If Engine Capital withdraws its nominees, abandons its solicitation or fails to comply with the universal proxy rules, any votes cast in favor of any Engine Capital Nominee will be disregarded and not be counted, whether the vote is provided on the Company’s WHITE proxy card or the Engine Capital [●] proxy card.

Although the Company is required to include all nominees for election on its proxy card, for additional information regarding the Engine Capital Nominees and any other related information, please refer to the Engine Capital proxy statement. You may receive solicitation materials from Engine Capital, including proxy statements and [●] proxy cards. The Company is not responsible for the accuracy or completeness of any information provided by or relating to Engine Capital or its nominees contained in solicitation materials filed or disseminated by or on behalf of Engine Capital or any other statements Engine Capital may make. Shareholders will be able to obtain, free of charge, copies of all proxy statements, any amendments or supplements thereto and any other documents (including the WHITE proxy card) when filed by the applicable party with the SEC in connection with the Annual Meeting at the SEC’s website (http://www.sec.gov).

If you are a registered holder and submit a validly executed WHITE proxy card but do not specify how you want to vote your shares with respect to the election of directors, then your shares will be voted in line with the Board’s recommendation with respect to the proposal, i.e., “FOR” the eight nominees that the Board proposes as set forth in this proxy statement. You are permitted to vote for fewer than eight nominees. If you vote for fewer than eight nominees, your shares will only be voted “FOR” with respect to those nominees you have so marked. However, if you are a registered holder and submit a validly executed WHITE proxy card but vote “FOR” more than eight nominees, all of your votes with respect to the election of directors will be invalid and will not be counted. It is, therefore, important that you do not vote “FOR” more than eight nominees, so that your vote with respect to this item is counted.

If you are a beneficial holder and properly mark, sign and return your WHITE voting instruction form or use your WHITE voting instruction form or notice to vote via internet, your shares will be voted as you direct your bank or broker. However, if you sign and return your WHITE voting instruction form but do not specify how you want your shares voted with respect to the election of directors, they will be voted in line with the Board’s recommendation with respect to the proposal, i.e., “FOR” the eight nominees that the Board proposes as set forth in this proxy statement, depending on the bank or broker through which you hold your shares. You are permitted to vote for fewer than eight nominees. If you vote for fewer than eight nominees, your shares will only be voted “FOR” with respect to those nominees you have so marked. If you are a beneficial holder and you vote “FOR” more than eight nominees on your WHITE voting instruction form, all of your votes with respect to the election of directors will be invalid and will not be counted. It is therefore important that you provide specific instructions to your broker or bank regarding the election of Directors so that your vote with respect to this item is counted.

Each nominee has consented to serve if elected. If any nominee becomes unavailable to serve as a Director before the Annual Meeting, the Board may designate a substitute nominee. In that case, the persons named as proxies will vote for the substitute nominee that the Board designates. At this time, the Board knows of no reason why any of the Board’s nominees would not be able to serve as a director if elected.

Knowledge, Skills and Experience of Nominees Plus our Designated Director

The chart below summarizes the number of Board nominees plus the designated director that possess knowledge, skills and experiences covering areas we believe are important to our sustainable success and certain demographic information.
