**NOTICE OF 2026 ANNUAL MEETING OF SHAREHOLDERS**<br>

To the shareholders of MSC Industrial Direct Co., Inc.:

NOTICE IS HEREBY GIVEN that the 2026 Annual Meeting of Shareholders (the "Annual Meeting") of MSC Industrial Direct Co., Inc., a New York corporation, will be held at 9:00 a.m., Eastern Time, on Wednesday, January 21, 2026 via live audio webcast at *www.virtualshareholdermeeting.com/MSM2026*, for the following purposes, as more fully described in the accompanying Proxy Statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.To elect the ten directors nominated by the Board of Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.To ratify the appointment of Ernst & Young LLP to serve as our independent registered public accounting firm for fiscal year 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.To approve, on an advisory basis, the compensation of our named executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.To approve Amendment No. 1 to our Amended and Restated Associate Stock Purchase Plan to increase the number of shares available for sale thereunder by 300,000 shares of our Class A common stock and to extend the plan's term; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.To consider and act upon such other matters as may properly come before the Annual Meeting or any adjournment or postponement thereof.

**The Board of Directors recommends that you vote "FOR" Items 1, 2, 3 and 4. The proxy holders will use their discretion to vote on other matters that may properly come before the Annual Meeting or any adjournment or postponement thereof.** 

Shareholders as of the close of business on November 24, 2025, the record date, are entitled to receive notice of, and to vote at, the Annual Meeting or any adjournment or postponement thereof.

The Annual Meeting will be held entirely online via live audio webcast at *www.virtualshareholdermeeting.com/MSM2026*. There will not be an option to attend the Annual Meeting in person.

Shareholders as of the close of business on the record date may participate in, and submit questions and vote during, the Annual Meeting by visiting *www.virtualshareholdermeeting.com/MSM2026*. To log in, you must enter the 16-digit control number included on your Notice of Internet Availability of Proxy Materials or proxy card or the instructions that you receive by e-mail. If you are a beneficial shareholder, you may contact the shareholder of record (e.g., your bank, broker or other nominee) if you have questions about obtaining your control number. If you do not have a control number, you may still access the live audio webcast of the Annual Meeting as a guest, but you will not be able to submit questions or to vote online during the meeting.

Whether or not you expect to participate in the Annual Meeting, your vote is important. To ensure your representation at the Annual Meeting, you are urged to cast your vote, as instructed in your Notice of Internet Availability of Proxy Materials or proxy card or the instructions that you receive by e-mail, as promptly as possible. If you received a copy of the proxy materials by mail, you may complete, sign, date and mail the proxy card in the envelope provided. Shareholders as of the close of business on the record date participating in the live audio webcast of the Annual Meeting may vote via the Internet during the meeting, even if they have voted via the Internet or by telephone or returned a completed proxy card. You may revoke your proxy or change your vote at any time prior to the taking of the vote at the Annual Meeting. If you participate in and vote during the Annual Meeting, your proxy will be revoked automatically and your vote during the meeting will be counted.

Shareholders are being notified of the Proxy Statement and form of proxy beginning on or about December 11, 2025.

**IMPORTANT: Your vote is important. Whether or not you plan to participate in the live audio webcast of the Annual Meeting, we encourage you to read this Proxy Statement and to vote your shares as soon as possible.**

**IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS** <br>**FOR THE ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON JANUARY 21, 2026:**<br>**The Notice of 2026 Annual Meeting and 2025 Proxy Statement and the 2025 Annual Report to Shareholders**<br>**are available at *https://investor.mscdirect.com/annual-results.***<br>

We are furnishing this Proxy Statement to you in connection with the solicitation of proxies by our Board of Directors (the "Board of Directors" or the "Board") to be used at the 2026 Annual Meeting of Shareholders (the "Annual Meeting"), or at any adjournment or postponement thereof. This Proxy Statement describes the matters to be presented at the Annual Meeting and related information that will help you vote your shares. References in this Proxy Statement to "MSC," the "Company," "we," "us," "our" and similar terms mean MSC Industrial Direct Co., Inc.

We have elected to take advantage of the "notice and access" rule of the United States Securities and Exchange Commission (the "SEC") that allows us to furnish proxy materials to shareholders online. We believe that electronic delivery expedites the receipt of proxy materials, while significantly lowering costs and reducing the environmental impact of printing and mailing full sets of proxy materials. As a result, on or about December 11, 2025, we mailed to our shareholders of record as of the close of business on November 24, 2025, either (i) a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy materials online and how to request paper copies of our proxy materials or (ii) a printed set of proxy materials, which includes the Notice of 2026 Annual Meeting of Shareholders, this Proxy Statement, our 2025 Annual Report to Shareholders and a proxy card. If you received a Notice of Internet Availability of Proxy Materials by mail, you will not receive a printed copy of the proxy materials unless you specifically request one. If you hold your shares through a bank, broker or other nominee, rather than directly in your own name, your intermediary will either forward to you a printed copy of the proxy materials or provide you with instructions on how you can access the proxy materials electronically.

| *Stock Ownership Requirements* | Our Chief Executive Officer must own at least six times the Chief Executive Officer's annual base salary in our common stock within five years from first being appointed or elected. |
| *Stock Ownership Requirements* | Within five years from first being appointed or elected, (i) our Chief Operating Officer must own at least four times the Chief Operating Officer's annual base salary in our common stock, (ii) each of our Executive Vice Presidents must own at least three times such Executive Vice President's annual base salary in our common stock, (iii) each of our Senior Vice Presidents must own at least two times such Senior Vice President's annual base salary in our common stock, and (iv) each of our Vice Presidents (who are executive officers) must own at least one time such Vice President's annual base salary in our common stock. |
| *Board and Board Committee Annual Composition and Performance*<br>*Evaluation* | The Nominating and Corporate Governance Committee annually reviews the composition and performance of the Board and the Board committees and considers among other factors, Board diversity and director tenure, age, skills, background and experience. |
| *Board and Board Committee Annual Composition and Performance*<br>*Evaluation* | The Board and each Board committee conduct annual self-evaluations to help ensure that the Board and the Board committee have the appropriate number and mix of members, skills and experience and the appropriate scope of activities, and considers, among other factors, Board diversity and director tenure, age, skills, background and experience. |
| *Annual Election of Directors* | All directors stand for election annually. |

In addition, our Corporate Governance Guidelines require each director nominee to tender an irrevocable conditional resignation that will be effective only upon both (i) such nominee's failure to receive the required vote at the next shareholders' meeting at which such nominee faces re-election and (ii) the Board's acceptance of such resignation. If an incumbent director fails to receive the required vote for re-election, the Nominating and Corporate Governance Committee will act on an expedited basis to make a recommendation to the Board as to whether to accept or reject the director's resignation, or to take other action. The Board will then consider the Nominating and Corporate Governance Committee's recommendation and take such action as it determines to be appropriate. |

| *Other Corporate Governance Practices* | We maintain a clawback policy to recoup incentive-based compensation in the event that we are required to prepare an accounting restatement due to our material noncompliance with any financial reporting requirement under the securities laws, as well as in cases of breach of non-competition and other post-employment restrictive covenants. |
| *Other Corporate Governance Practices* | We are committed to shareholder engagement and maintain a formal investor relations outreach program. |
| *Other Corporate Governance Practices* | The Nominating and Corporate Governance Committee oversees our ESG efforts and initiatives. |
| *Reclassification* | In the first quarter of fiscal year 2024, the Company completed the reclassification of its equity structure to eliminate its Class B Common Stock (the "Reclassification"), as contemplated by that certain Reclassification Agreement, dated as of June 20, 2023 (the "Reclassification Agreement"), with the Company, Mitchell Jacobson, Erik Gershwind, other members of the Jacobson / Gershwind family and certain entities affiliated with the Jacobson / Gershwind family (collectively, the "Jacobson / Gershwind Family Shareholders").

Although shareholder ratification of the Audit Committee's appointment of EY to serve as the Company's independent registered public accounting firm for fiscal year 2026 is not required, the Board is submitting the appointment of EY to the Company's shareholders for ratification as a matter of good corporate governance. The Board of Directors recommends that you vote "**FOR**" the ratification of the appointment of EY to serve as our independent registered public accounting firm for fiscal year 2026. Please see "***Ratification of the Appointment of Independent Registered Public Accounting Firm (Proposal No. 2)***" beginning on page [28](#iabb2672efea04a1781f060e066a7be4c_118) of this Proxy Statement.

**Advisory Vote to Approve Named Executive Officer Compensation (Proposal No. 3)**<br>

As required by Section 14A of the Exchange Act, we are giving our shareholders the opportunity to vote to approve or not approve, on an advisory basis, the compensation of our named executive officers, which is described in the "***Compensation Discussion and Analysis***" and "***Executive Compensation***" sections of this Proxy Statement. This vote is advisory, which means that the shareholder vote on the compensation of our named executive officers will not be binding on the Company, the Compensation Committee or the Board. Based on Company and individual performance, the Compensation Committee believes that compensation levels for fiscal year 2025 were appropriate and consistent with the philosophy and objectives of the Company's executive compensation programs. The Board of Directors recommends that you vote "**FOR**" the approval, on an advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement. Please see "***Advisory Vote to Approve Named Executive Officer Compensation (Proposal No. 3)***" beginning on page [62](#iabb2672efea04a1781f060e066a7be4c_217) of this Proxy Statement.

**Approval of Amendment No. 1 to our Amended and Restated Associate Stock Purchase Plan (Proposal No. 4)**<br>

Our Board adopted, subject to shareholder approval, an amendment to our Amended and Restated Associate Stock Purchase Plan (referred to in this proxy statement as Amendment No. 1 and the Stock Purchase Plan, respectively) to increase the number of shares available for sale thereunder by 300,000 shares of our Class A common stock to an aggregate of 2,150,000 shares of our Class A common stock and extend the plan's term through October 31, 2035. As of November 24, 2025, only 110,986 shares of our Class A common stock were available for future sale under the Stock Purchase Plan. After giving effect to Amendment No. 1, the total number of shares of Class A common stock of the Company remaining available for issuance under the Stock Purchase Plan will be approximately 410,986 shares. Our Compensation Committee, in consultation with our Board and senior management, believes that the ability of our associates to purchase shares of our Class A common stock under the Stock Purchase Plan helps achieve our short and long-term compensation objectives and that the amendment is necessary to ensure that we will have a sufficient reserve of our Class A common stock available under the Stock Purchase Plan. Our Board recommends that you vote "**FOR**" the approval of Amendment No. 1 to our Stock Purchase Plan. Please see "**Approval of Amendment No. 1 to our Amended and Restated Associate Stock Purchase Plan (Proposal No. 4)**" on page [64](#iabb2672efea04a1781f060e066a7be4c_1369) of this proxy statement.

**ELECTION OF DIRECTORS (PROPOSAL NO. 1)**<br>

The Board of Directors currently consists of nine members and has no vacancies. The Board intends to increase the size of the Board to ten members and appoint Ms. McIsaac to the Board on January 1, 2026. On the recommendation of the Nominating and Corporate Governance Committee, the Board has nominated the ten persons listed below for election as directors at the Annual Meeting. If elected, each nominee will serve until such term expires at the Company's 2027 Annual Meeting of Shareholders or until a successor is duly elected and qualified. All of the nominees are currently serving as directors and were elected to the Board at the Company's 2025 Annual Meeting of Shareholders, except Ms. McIsaac. Each nominee has agreed to be named in this Proxy Statement and to serve if elected.

Messrs. Erik Gershwind and Mitchell Jacobson are the nominees of the Jacobson / Gershwind Family Shareholders pursuant to the Reclassification Agreement.

Although the Company knows of no reason why any of the nominees would not be able to serve, if any nominee should become unavailable for election for any reason, the shares represented by a properly executed and returned proxy will be voted for any substitute nominee who shall be designated by the Board. There are no arrangements or understandings between any director or nominee for director and any other person pursuant to which such person was selected as a director or nominee for director of the Company.

**Board and Committee Evaluations; Qualifications of Nominees**<br>

The Nominating and Corporate Governance Committee annually reviews the composition and performance of the Board and Board committees, and considers, among other factors, Board diversity and director tenure, age, skills, background and experience. The Nominating and Corporate Governance Committee is responsible for recruiting, evaluating and recommending candidates to be presented for election or re-election to serve as members of the Board. The Board and each Board committee conduct annual self-evaluations to help ensure that the Board and each Board committee have the appropriate number and mix of members, skills and experience and the appropriate scope of activities. These self-evaluations also provide Board and Board committee members with insight for enhancing the effectiveness of their meetings. In evaluating the Board, the Nominating and Corporate Governance Committee has considered that our directors have a wide range of experience as senior executives of large publicly traded companies, and in the areas of accounting and business management consulting. In these positions, they have also gained industry experience and knowledge in core management skills that are important to their service on the Board, such as business-to-business distribution, supply chain management, mergers and acquisitions, strategic and financial planning, financial reporting, compliance, risk management, intellectual property matters and leadership development. Several of our directors also have experience serving on the boards of directors and board committees of other public companies, which provides them with an understanding of current corporate governance practices and trends and executive compensation matters. The Nominating and Corporate Governance Committee also believes that our directors have other key attributes that are important to an effective board of directors, including the highest professional and personal ethics and values, a broad diversity of business experience and expertise, an understanding of our business, a high level of education, broad-based business acumen and the ability to think strategically.

In addition to the qualifications described above, the Nominating and Corporate Governance Committee also considered the specific skills and attributes described in the biographical details below in determining whether each individual nominee should serve on the Board.

**Board Diversity**<br>

The Board of Directors does not maintain a formal policy with respect to the Board's diversity. However, as stated in the Company's Corporate Governance Guidelines, the Board seeks a board of directors that possesses, as a whole, diverse backgrounds, experiences, skills, expertise and qualifications necessary to support the current and future success of the Company and to function effectively in light of the Company's current and evolving business circumstances. With this goal in mind, the Nominating and Corporate Governance Committee considers, among other factors, Board diversity and director tenure, age, skills, background and experience in evaluating potential nominees for election or re-election to serve as members of the Board. In keeping with this commitment to diversity, our current director nominees possess a broad range of backgrounds, experiences, skills, expertise and qualifications. If our ten director nominees are elected, our Board will consist of 40% women and 10% individuals who identify as racially or ethnically diverse.

**CORPORATE GOVERNANCE**<br>

**Director Independence**<br>

Pursuant to the New York Stock Exchange (the "NYSE") listing standards, a majority of the members of the Board must be independent. The NYSE listing standards provide that a director does not qualify as "independent" unless the board of directors affirmatively determines that the director has no material relationship with the company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the company). The Board follows the criteria set forth in Section 303A of the NYSE listing standards to determine director independence. Our independence criteria are also set forth in Section 2 of our Corporate Governance Guidelines, a copy of which is available on our website at *https://investor.mscdirect.com/governance-documents*. In addition to applying these guidelines, the Board will consider all of the relevant facts and circumstances in making an independence determination.

The Board undertakes a review of director independence on an annual basis and as events arise which may affect director independence. Based upon this review, the Board determined that Mses. Goeser, Purcell and Seseri and Messrs. Kaufmann, Paladino, Peller and Aarnes are independent in accordance with Section 303A.02 of the NYSE listing standards as well as under our Corporate Governance Guidelines. The Board also determined that each member of the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee (see membership information below, under "― ***Board Committees***") is independent, including that each member of the Audit Committee is "independent" as that term is defined under Rule 10A-3(b)(1)(ii) of the Exchange Act.

In evaluating the independence of Mr. Aarnes, the Board considered that Mr. Aarnes is the president of ADI Global Distribution, a segment of Resideo Technologies, Inc. and a sister company to Ademco Inc., each of which are a customer and supplier of the Company. Sales to and purchases from Ademco Inc., ADI Global Distribution and Resideo Technologies, Inc. in fiscal year 2025 were made in the ordinary course of business and were immaterial in amount and significance.

In evaluating the independence of Ms. Goeser, the Board considered that Ms. Goeser is a director of Watts Water Technologies, Inc., which is a customer and a supplier of the Company. Sales to and purchases from Watts Water Technologies, Inc. in fiscal year 2025 were made in the ordinary course of business and were immaterial in amount and significance.

In evaluating the independence of Ms. Purcell, the Board considered that Ms. Purcell is the Chief Transformation Officer, North America of L'Oréal USA, which is a customer of the Company.

*Policy on Service on Other Audit Committees*

Under our Corporate Governance Guidelines, members of the Audit Committee may not serve as members of the audit committees for more than three public companies, including the Audit Committee of the Board.

***Compensation Committee***

*Principal Functions*

The principal functions of the Compensation Committee are to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• review and approve corporate goals and objectives relevant to the compensation of our Chief Executive Officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluate our Chief Executive Officer's performance in light of those goals and objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• determine and approve our Chief Executive Officer's compensation level based on its evaluation of the Chief Executive Officer's performance;

*Composition and Charter*

The Compensation Committee is currently comprised of Mses. Goeser, Purcell and Seseri and Messrs. Kaufmann, Paladino and Aarnes, each of whom the Board has determined to be independent under both the rules of the SEC and the listing standards of the NYSE. Ms. Goeser is the Chairperson of the Compensation Committee. The Board has approved a written charter for the Compensation Committee, a copy of which is available on our website at *https://investor.mscdirect.com/committee-composition*.

*Delegation of Authority*

The Compensation Committee does not delegate its responsibilities to any other directors or members of management. In January 2023, shareholders approved the adoption of the MSC Industrial Direct Co., Inc. 2023 Omnibus Incentive Plan (the "2023 Omnibus Incentive Plan") for the issuance of equity-based awards. Prior to 2023, equity-based awards were authorized under the MSC Industrial Direct Co., Inc. 2015 Omnibus Incentive Plan (the "2015 Omnibus Incentive Plan"). Under both the 2023 Omnibus Incentive Plan and the 2015 Omnibus Incentive Plan, the Compensation Committee is permitted to (i) delegate to a committee of one or more directors of the Company any of the authority of the committee under such plan and (ii) authorize one or more executive officers to take certain actions with respect to grants of awards under the 2023 Omnibus Incentive Plan to associates who are not directors or executive officers of the Company, in all cases to the extent permitted under applicable law, including the NYSE listing requirements. However, as a matter of policy, the Compensation Committee previously authorized the grants of awards under the 2015 Omnibus Incentive Plan and the Compensation Committee continues to authorize all grants of awards under the 2023 Omnibus Incentive Plan.

***Compensation Processes and Procedures***

The Compensation Committee makes all compensation decisions for our executive officers. In fiscal year 2025, the views and recommendations of Mr. Mitchell Jacobson, our Non-Executive Chairman of the Board, and Mr. Erik Gershwind, our Chief Executive Officer, were considered by the members of the Compensation Committee in their review of the performance and compensation of individual executives and will continue to be considered in the foreseeable future. In fiscal year 2025, Mr. Jacobson also provided input on Mr. Gershwind's compensation. In addition, the Compensation Committee obtains input from Mr. Gershwind on the compensation of the other named executive officers and other executive officers and senior officers. Our Human Resources department assisted the Chairperson of the Compensation Committee in developing the agenda for Compensation Committee meetings and worked with the Compensation Committee in developing agenda materials for the committee's review, including coordinating and presenting management's proposals and recommendations to the Compensation Committee with respect to executive and non-executive director compensation. In fiscal year 2025, Mr. Gershwind regularly attended Compensation Committee meetings, excluding portions of meetings where his own compensation is discussed. The Compensation Committee considers, but is not bound by, management's proposals and recommendations with respect to executive compensation.

The Compensation Committee has the sole authority to retain and terminate any third-party compensation consultant and to obtain advice and assistance from internal and external legal, accounting and other advisors. In connection with compensation decisions made by the Compensation Committee for fiscal year 2025, the Compensation Committee relied on competitive market data and analysis prepared by its independent compensation consultant, Frederic W. Cook & Co., Inc. ("FW Cook"). FW Cook provides research, market data and survey information and makes recommendations to the Compensation Committee regarding our executive compensation programs and our non-executive director compensation program. FW Cook advises the Compensation Committee on the competitiveness of our compensation arrangements and provides input, analysis and recommendations for the compensation paid to our named executive officers, other executives and non-executive directors. FW Cook provides data and analysis with respect to public companies having similar characteristics (including size, profitability, geography, business lines and growth rates) to those of the Company. As discussed under "***Compensation Risk Assessment***" on page [44](#iabb2672efea04a1781f060e066a7be4c_172) of this Proxy Statement, FW Cook also conducted a comprehensive risk assessment of our incentive-based compensation plans in fiscal year 2025 to assist the Compensation Committee in its compensation risk assessment. The Compensation Committee considers, but is not bound by, consultant recommendations with respect to executive and non-executive director compensation.

During fiscal year 2025, the Compensation Committee reviewed the independence of FW Cook, which included a consideration of the factors required by the NYSE listing standards, and determined that FW Cook is independent and that its service does not raise any conflicts of interest that would prevent it from providing independent and objective advice to the committee.

***Compensation Committee Interlocks and Insider Participation***

During fiscal year 2025, Mses. Goeser, Purcell and Seseri and Messrs. Kaufmann, Paladino and Aarnes served as members of the Compensation Committee. None of the members of the Compensation Committee were, during or prior to fiscal year 2025, an officer or employee of the Company or any of its subsidiaries or had any relationship with the Company other than serving as a director and as a de minimis shareholder. In addition, none of our directors has or had interlocking or other relationships with other boards or compensation committees or our executive officers that would require disclosure under Item 407(e)(4) of Regulation S-K.

***Nominating and Corporate Governance Committee***

*Principal Functions*

The principal functions of the Nominating and Corporate Governance Committee are to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identify individuals qualified to become members of the Board consistent with criteria approved by the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• annually review the background, qualifications and independence of the director nominees, and conduct an assessment of the Board's composition, in the context of the Board's needs and objectives, including consideration of Board diversity and director tenure, age, skills, background and experience;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• recommend to the Board nominees for membership on the Board, subject to the nomination rights provided to the Jacobson / Gershwind Family Shareholders pursuant to the Reclassification Agreement (please see *"****2025 Proxy Statement Summary—Corporate Governance Highlights***" beginning on page [2](#iabb2672efea04a1781f060e066a7be4c_25) of this Proxy Statement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop and recommend to the Board corporate governance guidelines and other corporate governance policies that are applicable to the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• review and approve any related party transaction between the Company and any executive officer, director, principal shareholder or immediate family member or other affiliate of such persons proposed to be entered into and, if appropriate, ratify any such transaction previously commenced and ongoing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• oversee the evaluation of the Board, the Board committees and our management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• oversee risk management practices for risks relating to ESG, governance and compliance matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• periodically review and assist the Board in succession planning for the Company's senior executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• oversee our ESG efforts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assist the Board in its oversight of our compliance with our ethics policies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• undertake an annual evaluation of its performance.

*Composition and Charter*

The Nominating and Corporate Governance Committee is currently comprised of Mses. Purcell and Seseri and Messrs. Kaufmann and Peller, each of whom the Board has determined to be independent under both the rules of the SEC and the listing standards of the NYSE. Mr. Kaufmann is the Chairperson of the Nominating and Corporate Governance Committee. The Board has approved a written charter for the Nominating and Corporate Governance Committee, a copy of which is available on our website at *https://investor.mscdirect.com/committee-composition*.

*Director Nomination Process*

The Nominating and Corporate Governance Committee is responsible for identifying and evaluating individuals qualified to become members of the Board and for recommending to the Board the individuals for nomination as members, subject to the nomination rights provided to the Jacobson / Gershwind Family Shareholders pursuant to the Reclassification Agreement (please see ***"2025 Proxy Statement Summary—Corporate Governance Highlights***" beginning on page [2](#iabb2672efea04a1781f060e066a7be4c_25) of this Proxy Statement). The Nominating and Corporate Governance Committee believes that the best director candidates will be those who have a number of qualifications, including independence, knowledge, judgment, integrity, character, leadership skills, education, experience, financial literacy, standing in the community and a sense of collegiality and cooperation that is conducive to a productive working relationship within the Board and between the Board and management. There are no specific, minimum or absolute criteria for Board membership. The Nominating and Corporate Governance Committee seeks a mix and diversity of backgrounds, experiences, skills, expertise and qualifications on the Board necessary to support the current and future success of the Company and to function effectively in light of the Company's current and evolving business circumstances. The Nominating and Corporate Governance Committee also believes that it is important for directors to have demonstrated an ethical and successful career. Such a career may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• experience as a senior executive of a publicly traded corporation, a management consultant, an investment banker, a partner at a law firm or registered public accounting firm or a professor at an accredited law or business school;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• experience in the management or leadership of a substantial private business enterprise or educational, religious or not-for-profit organization; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• such other professional experience as the Nominating and Corporate Governance Committee determines qualifies an individual for Board service.

At all times, the Nominating and Corporate Governance Committee will make every effort to ensure that the Board and its committees include at least the required number of independent directors, as that term is defined by applicable standards promulgated by the NYSE and the SEC. In addition, prior to nominating an existing director for re-election to the Board, the Nominating and Corporate Governance Committee will consider and review such existing director's attendance and performance, independence, experience, skills and contributions as an existing director to the Board.

The Nominating and Corporate Governance Committee may employ third-party search firms to identify director candidates, if so desired. The Nominating and Corporate Governance Committee will review and consider recommendations from a wide variety of contacts, including other directors, executive officers, community leaders and business contacts, as a source for potential director candidates. The Nominating and Corporate Governance Committee will also consider director candidates appropriately recommended by shareholders, including recommendations of director candidates pursuant to the Reclassification Agreement. All director candidates, including candidates appropriately recommended by shareholders, are evaluated in accordance with the process described above.

**Shareholder Recommendations for Director Candidates**<br>

Shareholders may recommend a director candidate to be considered for the Company's 2027 Annual Meeting of Shareholders by submitting the candidate's name in accordance with the provisions of the Company's Third Amended and Restated By-Laws, which require advance notice to the Company and certain other information.

submission of a recommendation by a shareholder does not guarantee the selection of the shareholder's candidate or the inclusion of the candidate in the Company's proxy materials; however, the Nominating and Corporate Governance Committee will consider any such candidate in accordance with the director nomination process described above.

**Universal Proxy Rules for Director Nominations**

In addition to satisfying the foregoing requirements under the Company's Third Amended and Restated By-Laws, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the Company's nominees for the 2027 Annual Meeting of Shareholders must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act.

**Director Meeting Attendance**

Each incumbent director attended, or participated by means of remote communication in, 75% or more of the aggregate number of meetings of the Board and committees of the Board on which the director served during fiscal year 2025. We encourage attendance by the directors at our annual meeting of shareholders. All but one of the Company's directors participated in the Company's 2025 Annual Meeting of Shareholders, which was held virtually via live audio webcast.

**Board Leadership Structure; Executive Sessions of the Independent Directors**<br>

The Board functions collaboratively and emphasizes active participation and leadership by all of its members. The Board currently consists of nine directors, each of whom, other than Messrs. Gershwind and Jacobson, is independent under our Corporate Governance Guidelines and applicable SEC rules and the NYSE listing standards.

Mr. Gershwind has served as our Chief Executive Officer since January 2013 and as a member of the Board since 2010. On January 1, 2026, Martina McIsaac will succeed Mr. Gershwind as our Chief Executive Officer. At such time, the Board expects to appoint Ms. McIsaac to the Board and Mr. Gershwind to the role of Non-Executive Vice Chair of the Board. Mr. Jacobson, who is one of our principal shareholders, was elected Chairman of the Board in January 1998 and became Non-Executive Chairman of the Board in January 2013. Mr. Jacobson previously served as our President from October 1995 until November 2003, and as our Chief Executive Officer from October 1995 until November 2005. The Board has separated the roles of Chairman and Chief Executive Officer since 2005 and has appointed an independent Lead Director since 2007.

The Board of Directors believes that the most effective Board leadership structure for the Company at the present time is for the roles of Chief Executive Officer and Chairman of the Board to be separated. Under this structure, our Chief Executive Officer is generally responsible for setting the strategic direction for the Company and for providing the day-to-day leadership over our operations, and our Chairman of the Board sets the agenda for meetings of the Board and presides over Board meetings. In addition, our independent directors meet at regularly scheduled executive sessions without members of management present. Mr. Paladino, as Lead Director, presides over the executive sessions of the independent directors. The Lead Director also has such other duties and responsibilities as determined by the Board from time to time. Those additional duties and responsibilities include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• making recommendations to the Board regarding the structure of Board meetings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• recommending matters for consideration by the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• determining appropriate materials to be provided to the directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• serving as an independent point of contact for shareholders wishing to communicate with the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assigning tasks to the appropriate Board committees with the approval of the Nominating and Corporate Governance Committee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• acting as a liaison between management and the independent directors.

The Board retains the authority to modify this leadership structure as and when appropriate to best address our unique circumstances at any given time and to serve the best interests of our shareholders.

**Role of the Board in Risk Oversight**<br>

The Board's role in risk oversight involves both the full Board and its committees. The full Board is responsible for the oversight of the Company's risk management and reviews our major financial, operational, compliance, cybersecurity, ESG, and reputational and strategic risks, including steps to identify, monitor, manage and mitigate such risks. In addition, each of the Board committees is responsible for oversight of risk management practices for categories of risks relevant to its functions. For example, the Audit Committee has oversight responsibility for our major financial risk exposures and the steps that management has taken to monitor and mitigate such exposures, including with respect to risk assessment and risk management and receives regular reports on Enterprise Risk Management (ERM) from senior management. Similarly, the Nominating and Corporate Governance Committee has oversight responsibility over ESG, governance and compliance matters and the Compensation Committee has oversight responsibility for our risk management practices for risks relating to our overall compensation structure, including review of our compensation practices, in each case with a view toward assessing associated risks. Please see "***Compensation Risk Assessment***" beginning on page [44](#iabb2672efea04a1781f060e066a7be4c_172) of this Proxy Statement.

The Audit Committee oversees our financial and risk management policies, including risk management policies and programs related to cybersecurity designed to monitor, mitigate and respond to cyber risks, threats, and reports. To more effectively prevent, detect and respond to information security threats, the Company's cyber risk management program is led by a dedicated Vice President of Information Security whose team is responsible for leading enterprise-wide cybersecurity strategy, policy, standards, architecture and processes. The Audit Committee receives regular reports from the Vice President of Information Security on, among other things, the Company's cyber risks and threats, the status of projects to strengthen the Company's information security systems, assessments of the Company's cybersecurity program and the emerging cyber threat landscape. Additionally, the Audit Committee has engaged a consulting firm to serve in the role of a cybersecurity advisor to the Audit Committee. In fulfilling this role, the consultant will engage with the Vice President of Information Security and other associates of the Company to evaluate the Company's cybersecurity maturity and advise the Audit Committee on cybersecurity gaps, best practices and industry trends on an ongoing basis.

The Company maintains cybersecurity insurance and regularly reviews its policy and levels of coverage based on current risks. All associates of the Company complete an annual cybersecurity training program in which specific threats and scenarios are highlighted based on the cyber risk management team's analysis of current cyber risks to the Company or as required by regulatory frameworks. Associates also receive ongoing communications regarding the importance of guarding against phishing, social engineering and other cyber attack vectors.

The Board as a group is regularly updated on specific risks in the course of its review of corporate strategy, business plans and reports to the Board by management and its respective committees. The Board believes that its leadership structure supports its risk oversight function by providing a greater role for the independent directors in the oversight of the Company.

**Corporate Governance Guidelines**<br>

We have adopted Corporate Governance Guidelines, which are available on our website at *https://investor.mscdirect.com/governance-documents*.

**Non-Executive Director Stock Ownership Guidelines**<br>

To more closely align the interests of our non-executive directors with those of our shareholders, the Board of Directors, upon the recommendation of the Nominating and Corporate Governance Committee, has adopted stock ownership guidelines for our non-executive directors. The stock ownership guidelines provide for each of our non-executive directors to own a minimum number of shares having a value equal to five times such non-executive director's base annual cash retainer on the first year of service on the Board (i.e., a value equal to $210,000 for non-executive directors whose tenure began before the adoption of the stock ownership guidelines, a value equal to $250,000 for Messrs.

All shares held by our non-executive directors, including unvested restricted stock units ("RSUs"), count toward the stock ownership guideline. The stock ownership guidelines provide for our non-executive directors to reach this ownership level within the later of five years from the date on which the guidelines were adopted or five years from the date on which the director was first elected. Once a non-executive director has attained the minimum ownership requirement, such non-executive director must maintain at least that level of ownership. If a non-executive director has not satisfied the applicable proportionate minimum stock ownership guideline, the director must retain an amount equal to 100% of the net shares received as a result of the vesting of RSUs. All of our non-executive directors are in compliance with their current stock ownership guidelines as of the date of this proxy statement.

**Overview of Director Compensation**<br>

The Compensation Committee is responsible for reviewing and making recommendations with respect to the compensation of our non-executive directors. The key objective of our non-executive directors' compensation program is to attract and retain highly qualified directors with the necessary skills, experience and character to oversee our management. In addition, our compensation program is designed to align the interests of the Board with the long-term interests of our shareholders. The compensation program is also designed to recognize the time commitment, expertise and potential liability required of active Board membership. We compensate our non-executive directors with a mix of cash and equity-based compensation. Directors who are also executives of the Company do not receive any compensation for their service on the Board.

The Compensation Committee's policy generally is to engage a compensation consultant every year to conduct a full review and benchmarking of our non-executive directors' compensation in order to ensure that our directors' compensation is in line with peer companies competing for director talent. In fiscal year 2025, the Compensation Committee engaged FW Cook to conduct a competitive analysis of our non-executive director's compensation using the same peer group used to benchmark executive compensation, and the findings were presented to the committee in August. Based on its review and the analysis provided by FW Cook, the Compensation Committee recommended to the Board changes to our non-executive director compensation program beginning in fiscal year 2026, which were approved by the Board. The changes will include increases in the annual cash and equity retainer amounts.

**Fiscal Year 2025 Director Compensation**<br>

For fiscal year 2025, we paid each non-executive director the following compensation:

(\*) Represents the aggregate fair value of the shares on the grant date and 50% of these shares vest on the first anniversary of the grant date and 50% vest on the second anniversary of the grant date.

Director compensation is paid quarterly in arrears. The cash compensation of directors who serve less than a full quarter is pro-rated for the number of days actually served. In addition, we reimburse our non-executive directors for reasonable out-of-pocket expenses incurred in connection with attending in-person Board or Board committee meetings and for fees incurred in attending continuing education courses for directors that are approved in advance by the Company.

In October 2014, the Compensation Committee recommended, and the Board approved, a change in the non-executive chairman compensation for Mr. Jacobson. Due to the level of his stock ownership, Mr. Jacobson and the Company would have needed to make a filing and he would have needed to pay a filing fee under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 in connection with the annual equity grant. Given these circumstances, the Board, upon the recommendation of the Compensation Committee, decided that it was appropriate to pay Mr. Jacobson cash in lieu of the annual equity grant, such amount to be paid quarterly in arrears.

Non-executive directors may elect to defer their cash or equity-based compensation under the MSC Industrial Direct Co., Inc. Deferred Compensation Plan for non-executive directors and consultants (the "Board of Directors Deferred Compensation Plan"). Deferrals are credited to a bookkeeping account and adjusted based on the performance of certain investment funds, which are available to employees participating in the Company's tax-qualified, defined contribution plan, that are selected by the participating director. One investment option assumes that the deferrals are invested in common stock with reinvestment of all dividends. The Board of Directors Deferred Compensation Plan does not pay above-market or preferential earnings on amounts deferred. Deferred RSUs and related dividend equivalents that, by their terms, are payable in shares of our Class A Common Stock are paid in shares. All other amounts deferred are payable in cash. Except in limited hardship circumstances, participants are paid upon termination of their service on the Board in either a single lump sum or in equal installments over up to five years.

In the event that a director ceases to provide services to the Company by virtue of such director's death, disability or retirement (which means cessation of services with approval of the Board), the vesting of all outstanding RSUs granted to

the non-executive director will accelerate and the shares underlying the RSUs will become fully vested. In addition, in the event of a change in control of the Company, the vesting of all outstanding RSUs granted to the non-executive director will accelerate and the shares underlying the RSUs will become fully vested. A change in control of the Company for purposes of the 2023 Omnibus Incentive Plan and the 2015 Omnibus Incentive Plan are described below under the section entitled "***Executive Compensation*** – ***Potential Payments Upon Termination or Change in Control*** – ***Change in Control Arrangements***" beginning on page [51](#ic69866914fe5416795029943d5dca2ed_13528) of this Proxy Statement. A change in control of the Company will be deemed to have occurred for purposes of the 2023 Omnibus Incentive Plan in the same circumstances as described under the 2015 Omnibus Incentive Plan.

**RATIFICATION OF THE APPOINTMENT OF** <br>**INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (PROPOSAL NO. 2)**<br>

The Audit Committee of the Board has appointed EY to serve as our independent registered public accounting firm for fiscal year 2026. EY has served as the Company's independent registered public accounting firm since 2002. The Audit Committee reviewed and discussed the performance of EY for fiscal year 2025 prior to its appointment of EY to serve as the Company's independent registered public accounting firm for fiscal year 2026.

EY has advised us that neither it nor any of its members has any direct or material indirect financial interest in the Company. We expect that a representative from EY will participate in the Annual Meeting. The representative will have an opportunity to make a statement if he or she so desires and is expected to be available to respond to appropriate questions from shareholders.

Although shareholder ratification of the Audit Committee's appointment of EY to serve as the Company's independent registered public accounting firm for fiscal year 2026 is not required, the Board is submitting the appointment of EY to the Company's shareholders for ratification as a matter of good corporate governance. If the Company's shareholders fail to ratify the appointment, the Audit Committee will reconsider its appointment of EY. Even if this appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the fiscal year if the Audit Committee determines that such a change would be in the best interests of us and our shareholders.

**Fees Paid to Independent Registered Public Accounting Firm**<br>

For fiscal years 2025 and 2024, EY billed us for its services the fees set forth in the table below. All audit and permissible non-audit services reflected in the fees below were pre-approved by the Audit Committee in accordance with established procedures.

The Audit Committee of the Board is required to pre-approve all audit and non-audit services provided by our independent registered public accounting firm and is not permitted to engage the independent registered public accounting firm to perform any non-audit services proscribed by law or regulation. The Audit Committee may delegate pre-approval authority to the Chairperson of the Audit Committee, in which case decisions taken are to be presented to the full Audit Committee at its next meeting.

The Audit Committee has considered whether, and has determined that, the provision of non-audit services by EY is compatible with maintaining auditor independence.

**AUDIT COMMITTEE REPORT**<br>

*The information contained under this "Audit Committee Report" shall not be deemed to be "soliciting material" or to be "filed" with the SEC, nor shall such information be incorporated by reference into any filing under the Securities Act or under the Exchange Act, or be subject to the liabilities of Section 18 of the Exchange Act, except to the extent specifically incorporated by reference into any such filing.*

The Audit Committee oversees the Company's financial accounting and reporting processes and systems of internal controls on behalf of the Board. The Company's management has the primary responsibility for the consolidated financial statements and the financial reporting process, including the systems of internal controls. The Audit Committee operates under a written charter adopted by the Board of Directors, a copy of which is available on our website at *https://investor.mscdirect.com/committee-composition*. The Audit Committee is directly responsible for the appointment, termination, compensation, retention and oversight of the work of our independent registered public accounting firm. The Audit Committee consists of the four directors named below, each of whom is an independent director as defined by applicable SEC rules and NYSE listing standards.

Each year, the Audit Committee evaluates the qualifications, performance and independence of our independent registered public accounting firm and determines whether to reengage the current firm. In doing so, the Audit Committee considers the quality and efficiency of the services provided by the independent registered public accounting firm, its capabilities, its technical expertise, its knowledge of our operations and the appropriateness of its fees for audit and non-audit services. Part of that process includes the solicitation of feedback from members of management and the Chairperson of the Audit Committee. Based on this evaluation, the Audit Committee appointed EY as our independent registered public accounting firm to examine our consolidated financial statements and internal control over financial reporting for fiscal year 2025. EY has served as the Company's independent registered public accounting firm since 2002. The Audit Committee also oversees the periodic required rotation of the lead audit partner every five years or at an earlier date, as required by SEC rules. It is directly involved in that process through interviews with prospective candidates, assessment of their professional experiences and evaluating input received from their audit firm and management.

The Company's senior financial officers and executive leadership supervise our systems of internal controls and the financial reporting process. Our independent registered public accounting firm performs an independent audit of our consolidated financial statements in accordance with generally accepted auditing standards and expresses an opinion on these consolidated financial statements. In addition, our independent registered public accounting firm expresses its own opinion on the Company's internal control over financial reporting. The Audit Committee monitors these processes.

The Audit Committee has reviewed and discussed with both the management of the Company and our independent registered public accounting firm our audited consolidated financial statements for fiscal year 2025, as well as management's assessment and our independent registered public accounting firm's evaluation of the effectiveness of our internal control over financial reporting. Our management represented to the Audit Committee that our audited consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America.

The Audit Committee discussed with our internal auditors and our independent registered public accounting firm the overall scope and plans for their respective audits. The Audit Committee met with the Company's Director of Internal Audit and the independent registered public accounting firm, with and without management present, to discuss the results of their audits, their evaluations of our internal controls, including our internal control over financial reporting, and the overall quality of our financial reporting.

The Audit Committee also inquired about significant business and financial reporting risks, reviewed the Company's policies for risk assessment and risk management, reviewed the regular reports on Enterprise Risk Management (ERM) from the Director, Risk Management and assessed the steps management is taking to address these risks.

The Audit Committee also discussed with our independent registered public accounting firm the matters required to be discussed by applicable requirements of the Public Company Accounting Oversight Board and the SEC. The Audit Committee also received the written disclosures and the letter from our independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding EY's communications with the Audit Committee concerning independence, and has discussed with EY its independence as our independent registered public accounting firm. The Audit Committee has also considered whether the provision of non-audit services by our independent registered public accounting firm is compatible with maintaining the independence of the auditors. The Audit Committee's policy is to pre-approve all audit and permissible non-audit services provided by our independent registered public accounting firm, therefore all audit and permissible non-audit services performed by our independent registered public accounting firm during fiscal years 2025 and 2024 were pre-approved by the Audit Committee in accordance with established procedures.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board (and the Board approved) that the audited consolidated financial statements of the Company be included in its Annual Report on Form 10-K for the fiscal year ended August 30, 2025, which was filed with the SEC on October 23, 2025.

<br>**Executive Summary**<br>

***Fiscal Year 2025 Performance Highlights***

In fiscal year 2025, we built upon our 85-year legacy and harnessed long-term momentum driven by the continued advancement of our strategic initiatives aimed at driving profitable growth. Against a backdrop of ongoing market volatility, we returned to sales growth exiting the fiscal year as momentum began to build with noticeable improvement in our most profitable customer base, the Core customer. We generated another strong year of cash flow from operations of more than $330M, that represented 169% of net income. This continued strength in cash generation supported our sustained commitment to returning capital to shareholders in the form of dividends and share repurchases totaling $229M during the fiscal year.

We strengthened our position to drive long-term profitable growth following further advancement of the initiatives embedded in our Mission Critical strategy. The largest scope of work was improving our E-commerce experience, which underpinned our efforts in reenergizing the Core customer. We launched our enhanced website entering the second half of the fiscal year which included an improved product discovery platform, a streamlined checkout experience and increased personalization throughout the customers' buying journey. Complementing the launch of our website was an enhanced marketing campaign focused on increasing awareness of our website upgrades and our more competitive pricing structure that we introduced towards the end of fiscal year 2024. As a result of these actions, we began to see improving average daily sales trends on the website, which contributed to the Core customer improvement we experienced during the second half of the fiscal year.

We also made progress in other key operational areas of the business in fiscal 2025. We enhanced seller coverage and effectiveness by leveraging an enhanced data-driven territory model, strengthening our onboarding process, and introducing tools that help our sales team more easily identify untapped opportunities. We quickly began to see the benefits from of these endeavors as sales per representative per day trends improved during the second half of the fiscal year. Second, we continued to expand our solutions footprint through further share capture, resulting in 10% growth in our installed vending machine units and 20% growth in the number of In-Plant programs.

The execution of our initiatives throughout fiscal 2025 drove a return to growth in the fourth quarter, and we're entering fiscal 2026 with strong momentum. We are laser focused on executing across our productivity pipeline, which, combined with moderating operating expenses, creates compelling incremental margin opportunity. This positions MSC strongly on the path towards our long-term targets of adjusted operating margin in the mid-teens and delivering 400 basis points of growth above the Industrial Production index over the cycle.

Our operating performance in fiscal year 2025 was highlighted by the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our net sales decreased 1.3% to $3.77 billion;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our gross profit decreased 2.3% to $1.54 billion;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our operating expenses increased 4.8% to $1.22 billion, as compared to $1.17 billion in the prior fiscal year;

**<u>[**TABLE OF CONTENTS**](#iabb2672efea04a1781f060e066a7be4c_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our operating income was $301.6 million, representing a decrease of 22.8% from operating income of $390.4 million in the prior fiscal year;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our diluted earnings per share was $3.57 versus $4.58 in the prior fiscal year;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We generated $333.7 million of cash from operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We paid out $189.7 million in quarterly cash dividends compared to $187.3 million in the prior fiscal year;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We repurchased $39.3 million of MSC's Class A Common Stock.

**Compensation Philosophy and Objectives**<br>

We believe that the quality, skills and dedication of our executive officers are critical factors affecting the Company's performance and, therefore, long-term shareholder value. Our key compensation goals for our associates, including the NEOs, are to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• create a performance driven culture based on personal accountability by linking rewards to Company and individual performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide a market competitive compensation opportunity to enable the Company to attract, retain and motivate highly talented associates; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• align our executives' interests with those of our shareholders.

Accordingly, in determining the amount and mix of compensation, the Committee seeks to provide a market competitive compensation package, structure annual and long-term incentive programs that reward achievement of performance goals that directly correlate to the enhancement of sustained, long-term shareholder value, and promote executive retention.

(1)Adjusted Operating Profit, Average Daily Sales Growth and Adjusted Return on Invested Capital are non-GAAP financial measures. See Appendix A to this Proxy Statement for definitions and reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures.

The Committee does not maintain policies for allocating among short-term and long-term compensation or among cash and non-cash compensation. Instead, the Committee maintains flexibility and adjusts different elements of compensation based upon its evaluation of the Company's key compensation goals. As a general matter, the Committee seeks to utilize equity-based awards to motivate executives to enhance long-term shareholder value and to manage the dilutive effects of equity compensation through the Company's share repurchase program.

While compensation levels may differ among NEOs based on competitive factors and the role, responsibilities and performance of each NEO, there are no material differences in the compensation philosophies, objectives or policies for our NEOs. However, as an executive assumes more responsibility, a greater percentage of total target cash compensation is allocated to annual performance bonus compensation, and a greater percentage of total direct compensation is allocated to equity compensation. The Committee does not maintain a policy regarding internal pay equity, but the Committee considers internal pay equity as part of its overall review of our compensation programs.

**Shareholder Engagement and "Say-on-Pay" Vote**<br>

We are committed to engaging with our shareholders. We maintain a formal investor relations outreach program to solicit the views of institutional shareholders on a variety of topics, including executive compensation. As part of this program, and during fiscal year 2025, our senior management and investor relations team met with many institutional investors, including our top 25 investors with actively managed funds, through investor conferences, investor roadshows, virtual meetings and telephone conferences.

We are also committed to continued engagement between shareholders and the Company through our annual "say-on-pay" advisory vote on executive compensation. At our 2025 Annual Meeting of Shareholders held on January 22, 2025, the advisory vote received the support of more than 98% of the votes cast at the meeting. In its review of our executive compensation programs, the Committee carefully considered the results of the 2025 advisory vote on executive compensation. In addition, we continually monitor the views of our major institutional shareholders to assure alignment of our compensation practices with our institutional shareholders' standards. The Committee will consider feedback from our shareholders along with the results of the "say-on-pay" advisory vote as it completes its annual review of each pay element and the total compensation packages for our NEOs with respect to the next fiscal year.

**Compensation Committee**<br>

The Committee is directly responsible for determining, in consultation with the Board, the G&Os of our executive compensation programs and for the ongoing review and evaluation of our compensation programs to determine whether they are achieving their intended objectives. The Committee also evaluates the design and mix of our compensation programs and makes adjustments, as appropriate, to achieve our compensation philosophy. In consultation with the Board, the Committee has primary responsibility for overseeing and approving all compensation matters relating to, and setting the compensation levels of, the NEOs and our other executive officers and senior officers. The Committee also administers our equity compensation plans. Members of management and independent consultants provide input and recommendations to the Committee, but decisions are ultimately made by the Committee.

**How Compensation Decisions Are Made**<br>

Each August, the Committee receives a formal presentation from FW Cook, its independent compensation consultant, on the competitiveness of the Company's compensation programs, as well as the alignment of the Company's compensation programs with the Company's compensation objectives. Based on the benchmarking data prepared by the Committee's independent compensation consultant and the consultant's evaluation of the Company's compensation programs, our Human Resources department, with input from our Chief Executive Officer and our Chief Financial Officer, compiles management's recommendations for our annual performance bonus plan and equity award grants for the upcoming fiscal year. The Committee meets in September to review and consider the preliminary management recommendations. At its October meeting, when the Company's fiscal year financial results are being considered by the Board, the Committee reviews the achievement of the prior fiscal year's annual performance bonus plan financial metrics and each NEO's individual G&Os, and approves the annual bonus payouts. Equity grants are approved in early November, after the Company's Annual Report on Form 10-K has been filed with the SEC. Depending on Company or individual circumstances, base salary adjustments are made for our executive officers and other senior officers at the time of their individual performance reviews, and the Committee also may make other compensation decisions during the year.

**Role of Executive Officers in Compensation Decisions**<br>

As part of its process, the Committee meets with our Chief Executive Officer and our Chairman to obtain recommendations with respect to the structure of our compensation programs and compensation decisions, including the performance of individual executives. The Committee obtains our Chairman's input on the compensation of our Chief Executive Officer, and our Chief Executive Officer provides the Committee with input on the compensation of the other NEOs and other executive officers and senior officers. Our Human Resources department collects and analyzes relevant data, including comparative compensation data prepared by FW Cook, which is used by the Committee to inform compensation decisions.

**Compensation Consultant**<br>

The Committee has the sole authority to retain and terminate any third-party compensation consultant and to obtain advice and assistance from internal and external legal, accounting and other advisors. Since 2009, the Committee has relied on competitive market data and analysis prepared by its independent compensation consultant, FW Cook. To assist the Committee with its compensation decisions, FW Cook recommends to the Committee peer companies and general industry survey data for benchmarking, and provides competitive compensation data, benchmarking and analysis relating to the compensation of our Chief Executive Officer and other executives and senior officers based on such market data. FW Cook also furnishes the Committee with competitive compensation data and analysis for non-executive directors. In addition, FW Cook assists the Committee with its risk assessment of our compensation programs and advised on the methodology used for our 2025 CEO pay ratio disclosure. FW Cook has not provided any other services to the Company and will not provide any other services to the Company without the approval of the Committee.

**Fiscal Year 2025 Executive Compensation**<br>

***Summary of Fiscal Year 2025 Compensation Decisions***

Based on Company and individual performance, the Committee believes that compensation levels for fiscal year 2025 were appropriate and consistent with the philosophy and objectives of the Company's compensation programs and reflect the Company's pay for performance strategy. Base salaries were adjusted to be consistent with the market and equity compensation was awarded to align with market and annual grant practices to create long-term incentives for retention and future performance.

Our results in fiscal year 2025 reflected organic revenue growth and adjusted operating profit, as computed for purposes of our annual performance bonus plan, between the threshold and target level. As a consequence, bonus payouts for Company financial performance were approximately 93% of that combined target for our NEOs. In addition, the Committee determined that Mr. Gershwind, Ms. McIsaac, Mr. Dongre and Ms. Shacklett achieved aggressive targets in respect to their individual G&Os, resulting in a performance multiplier of 100% of their target awards based on G&O performance, yielding a combined payout of 95% of target. Mr. Clark was significantly above target in respect to his individual G&Os, resulting in a performance multiplier of 150% of his target awards based on G&O performance, yielding a combined payout of 108% of target.

***Elements of Compensation***

We allocate compensation among the following components for our NEOs:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• base salary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• annual performance bonuses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• stock-based compensation in the form of PSUs and RSUs; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other benefits.

***Base Salary***

Base salaries for our executive officers are established based on the scope of their responsibilities and the competitive market compensation paid by other companies for similar positions, as well as salaries paid to the executives' peers within the Company. Base salaries are reviewed each year in connection with the executives' performance evaluations and may be adjusted based on competitive market data, individual performance and promotions or changed responsibilities. The Committee seeks to target base salary levels at or below the market median. However, in individual cases, base salary levels may differ based upon the executive's experience, individual performance and other considerations. In fiscal year 2025, all NEO base salaries were increased consistent with the overall budget for base salary increases for executive and senior officers with the exception of Mr. Gershwind who did not have a salary increase in fiscal year 2025.

(1)Ms. Actis-Grande departed the Company on August 8, 2025. Base salary as of Ms. Actis-Grande's departure date was $630,000 and base salary as of the end of fiscal year 2024 was $600,000, representing a 5.0% year over year increase.

(2)In addition to the base salary reported above, Mr. Clark received an annual stipend of $110,000 for his services as interim Chief Financial Officer. The portion of the annual stipend applicable to fiscal year 2025 was $4,227.

***Annual Performance Bonus Plan***

For fiscal year 2025, we measured financial performance under our annual performance bonus plan based on two financial metrics – organic revenue growth (on an average daily sales ("ADS") basis) and adjusted operating profit, weighted at 37.5% each. Our performance bonus plan for fiscal year 2025 fixed payout levels based on achievement of financial metrics measured against our fiscal year 2025 operating plan. As in previous years, the remaining 25% of the target bonus opportunity was based on the achievement of individual G&Os. In addition, award opportunities were subject to an individual performance multiplier. Maximum bonus payout opportunities in fiscal year 2025 were capped at 188% of target.

Bonus award opportunities are designed to provide market-based, competitive award opportunities. The Committee retains discretion to modify annual bonus payouts otherwise payable under the performance bonus plan where it determines that bonus amounts are not reflective of Company and individual performance. The Committee did not make any modifications to the annual bonus payouts for fiscal year 2025. For threshold, target and maximum dollar amounts of performance bonus opportunities under our performance bonus plan for the NEOs, please see the Fiscal Year 2025 Grants of Plan-Based Awards table on page [48](#iabb2672efea04a1781f060e066a7be4c_187) of this Proxy Statement.

*Company Financial Metrics*

Company financial metrics are established by the Committee based on the Company's business plan, as reviewed and approved by the Committee, and consistent with analysts' consensus expectations. For fiscal year 2025, Company financial metrics were:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• organic revenue growth (ADS) (year-over-year); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adjusted operating profit.

The Committee used these financial metrics similar to prior fiscal years because revenue growth and operating profit are important drivers of value creation for our shareholders.

In setting award opportunities, the plan provides for three payout levels based on achievement of Company financial metrics, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• threshold – payout at 25% of target based on a minimum achievement level of performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• target – payout at 100% of target based on achievement of target level of performance, which is aligned with our budget;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• stretch – payout at 125% of target based on achievement of expected level of performance; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maximum performance – payout at 200% of target based on superior performance.

The following table sets forth the payout level opportunities available for our NEOs in fiscal year 2025 for each Company financial metric as a percentage of the target award (with each financial metric having a weighting of 37.5%) based on different levels of performance and the actual performance achievement. No payout for any financial metric is made if the threshold performance level for that financial metric is not achieved. For performance between the different payout levels indicated below, straight-line interpolation is used to arrive at the actual payout:

*Individual Goals and Objectives and Performance Multiplier*

Achievement of individual G&Os has a 25% weighting in our performance bonus plan. Individual G&Os are established annually and include strategic initiatives with both financial and non-financial goals. Executives are evaluated based upon achievement of these meaningful goals. At the end of each year, our CEO evaluates performance against the pre-established individual objectives for officers other than himself and submits a recommendation to the Committee. The Committee evaluates our CEO's performance against his pre-established individual objectives. Based on the Committee's evaluation of the CEO and the CEO's recommendations, the Committee determines and approves the achievement and payout level of the G&Os for each executive officer. Payout levels based on achievement of the individual G&Os are subject to an individual performance multiplier. We designed our performance bonus plan with this individual performance multiplier to provide increased earning potential based on individual performance, consistent with our performance-based compensation philosophy. The following table sets forth the performance multiplier payout level opportunities for our NEOs for the individual G&Os based on different levels of general performance:

---

| | |
|:---|:---|
| **Individual G&O Performance Levels** | **Performance Multiplier %** |
| Growth Opportunity | &nbsp;&nbsp;&nbsp;&nbsp;50% |
| Achieving Aggressive Targets | &nbsp;&nbsp;&nbsp;&nbsp;100% |
| Significantly Above Target | &nbsp;&nbsp;&nbsp;&nbsp;150% |

---

*Achievement of Individual G&Os*

For fiscal year 2025, the Committee determined that Mr. Gershwind, Ms. McIsaac, Mr. Dongre and Ms. Shacklett achieved aggressive targets in respect to their individual G&Os, resulting in a performance multiplier of 100% of target. Mr. Clark was significantly above target in respect to his individual G&Os, resulting in a performance multiplier of 150% of his target awards based on G&O performance.

The Committee considered the individual performance goals and performance of each NEO who was eligible for an annual performance bonus award at the end of the fiscal year, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Erik Gershwind –* Navigated the Company through a turbulent economic climate that experienced both market volatility and uncertainty introduced by tariﬀs.

*Fiscal Year 2025 Performance Bonuses for NEOs*

The following table summarizes the computations for the performance bonuses earned based on the Company's performance and the NEO's individual G&O performance for fiscal year 2025:

(1) Ms. Actis-Grande departed the Company on August 8, 2025, and was not eligible to receive any of her target annual performance bonus of $437,365 for fiscal year 2025.

The Committee retains discretion to modify annual bonus payouts otherwise payable under the performance bonus plan. After reviewing the bonus payouts earned by the NEOs, the Committee did not make any modifications to the bonus payouts for fiscal year 2025. Mr. Clark received a stipend in fiscal year 2025 for his role as Interim Chief Financial Officer which was included in his 2025 actual bonus calculation.

The Committee believes that bonuses awarded under our annual performance bonus plan appropriately reflected the Company's performance and appropriately rewarded the performance of the NEOs.

***Long-Term Stock-Based Compensation***

The Committee grants PSUs and RSUs. For fiscal year 2025, PSUs represented 50% of the grant date value of equity awards to executive officers, with the remaining 50% of the grant date value represented by RSUs. We believe that providing combined grants of RSUs and PSUs effectively focuses our executives on delivering long-term value to our shareholders, while aligning compensation with performance, as PSUs only vest if the Company achieves long-term target performance criteria specified by the Committee. RSUs reward and retain the executives by offering them the opportunity to receive MSC shares on the date the restrictions lapse so long as they continue to be employed by the Company. PSUs cliff vest after three years, with payouts ranging from 0% to 200% of target (with straight-line interpolation used for determining payouts with achievement between threshold and target and target and maximum performance levels) based upon our average adjusted return on invested capital over a period of three fiscal years (from fiscal year 2025 through fiscal year 2027 for the fiscal year 2025 grants), subject to the grantee's continued employment. No payout is made if the performance is below the threshold level.

In setting performance levels, the Committee seeks to set a target level that is a reasonable goal aligned with the Company's operating plan, with the maximum performance level requiring significant outperformance and the threshold level representing a minimally acceptable performance level. The Committee has discretion to adjust the computation of the performance level achieved for purposes of determining the number of PSUs that are earned as it deems appropriate to reflect the impact of items that are not indicative of ongoing operating results, including such items as restructuring and severance charges and acquisitions. Dividends are not paid on unvested RSUs and PSUs; instead, dividend equivalent units accrue on unvested RSUs and PSUs and vest at the same times as the underlying RSUs and PSUs, subject in the case of PSUs to the same performance vesting requirements. The Committee does not have a fixed policy on allocating between RSUs and PSUs, but seeks to balance the retentive values of RSUs and PSUs, while aligning PSU payouts with long-term growth target levels.

RSUs vest 25% ratably over four years for associates at the director and above levels, including executive officers. The Committee believes that this aspect of our equity compensation package promotes executive retention and management stability, and fosters focus on long-term growth aligned with building shareholder value.

In granting equity awards, the Committee takes into consideration the dilutive effect on earnings to our shareholders once the shares are issued or vested, and we seek to mitigate this effect by repurchasing shares from time to time under the Company's share buyback program. We also evaluate and benchmark the Company's annual equity grants as a percentage of outstanding shares and the fully diluted overhang of outstanding equity awards plus shares available for grant.

As discussed below under "— ***Change in Control Arrangements****,*" the vesting of unvested stock options, RSUs and PSUs only accelerates if there is both a change in control of the Company and if such awards are not continued, assumed or substituted in connection with the transaction or if there is a termination of employment without cause (or for executives who participate in our executive change in control severance plan, a termination by the executive for good reason) within one year (two years for executives who participate in our executive change in control severance plan) following the change in control. Because there is no acceleration of awards unless there is both a change in control and either the awards would be terminated or the grantee's employment is terminated following the change in control, our outstanding equity awards are subject to "double trigger" accelerated vesting.

*Equity Grants During Fiscal Year 2025*

The number of PSUs and RSUs granted to the NEOs in fiscal year 2025, and the grant date fair value of these awards determined in accordance with FASB ASC Topic 718, are shown in the Fiscal Year 2025 Grants of Plan-Based Awards table on page [48](#iabb2672efea04a1781f060e066a7be4c_187) of this Proxy Statement. Equity awards granted in November 2024 were benchmarked against the competitive market data.

The following table sets forth the performance level opportunities for the PSUs granted in November 2024 with a performance period that runs through fiscal year 2027. For performance between the different payment levels indicated below, straight-line interpolator is used to arrive at the actual payment.

*Completed 2022 Equity Grants Earned During Fiscal Year 2025*

The PSUs granted in November 2022 were not earned based on the Company's average adjusted return on invested capital for the three year fiscal performance period that ended in fiscal year 2025 falling below threshold as shown below:

(1)See Appendix A to this Proxy Statement for information regarding non-GAAP financial measures, including a reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures.

NEOs would have become vested in November 2025 if the PSUs were earned.

*Administration of Equity Award Grants*

RSU and PSU awards to executive officers and other senior officers are approved on an annual basis by the Committee in early November, after the Company's Annual Report on Form 10-K has been filed with the SEC. The approval process specifies:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the individual receiving the grant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the dollar value of RSUs or PSUs, with the number of RSUs or PSUs to be determined based on the closing price of our shares of Class A Common Stock on the date of grant.

Grants for associates other than officers also are approved by the Committee, and the Committee does not delegate authority for making grants to any member of management. Our current policy provides that off-cycle grants and promotion and new hire grants may be approved at regularly scheduled or special Committee meetings. We do not time our equity award grants relative to the release of material non-public information.

*Hedging Policy; Pledging*

Under our insider trading policy, executive officers and Board members may not engage in short-selling, margin transactions, trading in exchange-traded options or hedging or monetization transactions, such as zero-cost collars and forward sale contracts, with respect to our common stock. Our insider trading policy also prohibits pledging Company shares in margin accounts. Executive officers and Board members may only pledge Company shares as collateral for a loan outside of a margin account up to 10% of their ownership of Company shares (excluding options and unvested RSUs and PSUs), provided that shares required to be held pursuant to our stock ownership guidelines may not be pledged. Our

**<u>[**TABLE OF CONTENTS**](#iabb2672efea04a1781f060e066a7be4c_7)</u>**

Nominating and Corporate Governance Committee retains discretion to permit limited exceptions to the 10% restriction. None of our executive officers or Board members currently have pledged any Company shares.

***Benefits and Perquisites***

We provide our executives with certain health and insurance benefits, as well as an automobile allowance and other perquisites. Our executives can participate in the MSC Industrial Direct 401(k) Plan (which includes Company matching contributions of 50% up to the first 6% of a participant's contributions), the MSC Industrial Direct Co., Inc. Amended and Restated Associate Stock Purchase Plan (the "Associate Stock Purchase Plan") and our health benefit and insurance programs on the same basis as our associates. Mr. Gershwind does not participate in the Associate Stock Purchase Plan. We also provide our executives with either a car allowance or a leased vehicle, and a spouse or guest of our executives are invited to attend our annual company award event.

We do not provide any other executive perquisites such as supplemental life insurance, financial planning, country club membership, or special health benefits.

***Change in Control Arrangements***

Our NEOs participate in our executive change in control severance plan. For a description of our executives' change in control arrangements, please see "***Executive Compensation*** — ***Potential Payments Upon Termination or Change in Control***" beginning on page [51](#iabb2672efea04a1781f060e066a7be4c_199) of this Proxy Statement.

We believe that our executive change in control severance plan promotes the stability of our business and our key personnel during the transition period surrounding a change in control transaction, and would keep our executives focused on the business rather than on their employment prospects. The plan serves to assure the retention of key executives in order to successfully execute a change in control transaction. To this end, the change in control benefits only are provided if the executive remains with the Company through the change in control and if there is a termination of employment without cause or by the executive for good reason, commonly referred to as a "double trigger." Please see "***Executive Compensation*** — ***Potential Payments Upon Termination or Change in Control*** — ***Change in Control Arrangements***" on page [51](#ic69866914fe5416795029943d5dca2ed_13528) of this Proxy Statement.

Under both the 2015 Omnibus Incentive Plan and the 2023 Omnibus Incentive Plan and the forms of PSU awards respectively thereunder, in the event of a change in control transaction pursuant to a merger agreement, outstanding stock options and RSU and PSU awards shall be continued, assumed or substituted if so provided in the merger agreement. In the case of PSUs, if the merger agreement provides for assumption, then the PSUs would convert to RSUs based on the target level of performance, provided that if the change in control occurs after the first full year of performance and the performance level is higher than the target level, the PSUs would convert to RSUs at such higher level. If the merger agreement does not provide for continuation, assumption or substitution of equity awards, the vesting of outstanding options shall accelerate, the restrictions applicable to all RSU awards shall lapse and PSUs will vest and be earned at the target level of performance, except if the change in control occurs after the first fiscal year of the performance period and the actual level of achievement based on (1, 2 or 3 full fiscal years) is higher than the target level, then the actual level of achievement shall be used to determine the level of achievement of the performance criteria. In addition, following any change in control, if an associate's employment is terminated without cause within one year following the change in control, vesting shall also accelerate. For executive officers who participate in our executive change in control severance plan, the protection period is extended to two years and vesting also accelerates in cases of termination by the executive for good reason. The Committee believes that these provisions provide the Board with appropriate flexibility to address the treatment of options and RSU and PSU awards in a merger or similar transaction that is approved by the Board, while providing appropriate protections to our executives and other associates in transactions which are not approved by the Board. Because there is no acceleration of awards unless there is both a change in control and either the awards are terminated or the grantee's employment is terminated following the change in control, our outstanding equity awards are subject to "double trigger" accelerated vesting. Please see the section entitled "***Executive Compensation*** — ***Potential Payments Upon Termination or Change in Control*** — ***Equity Award Plans***" beginning on page [52](#ic69866914fe5416795029943d5dca2ed_13527) of this Proxy Statement.

***MSC Executive Severance Plan***

Under the MSC Executive Severance Plan, amended and restated in March 2023, Vice Presidents, Senior Vice Presidents and Executive Vice Presidents of the Company are eligible to receive certain severance benefits in the event of limited qualifying termination events. Please see the section entitled "***Executive Compensation*** — ***Potential Payments Upon Termination or Change in Control*** — ***MSC Executive Severance Plan***" beginning on page [53](#ic69866914fe5416795029943d5dca2ed_13529) of this Proxy Statement.

**Competitive Positioning**<br>

The Committee uses peer group information, together with compensation data by functional position derived from general industry surveys, as a reference point for assessing compensation levels and practices, based on market data from FW Cook. The Committee, with the assistance of FW Cook, annually reviews and approves the list of companies to ensure its appropriateness. In fiscal year 2025, based on a qualitative review of our peer group, the Committee added Boise Cascade Company to the peer group and removed Beacon Roofing Supply, Inc. and Patterson Companies, Inc.

Key criteria for inclusion include similar size, industry focus, scope and complexity of business as well as companies with which we compete for executive talent. The fiscal year 2025 peer group is listed in the chart below, together with comparative fundamental statistics.

The Committee generally seeks to set base salary, total target cash compensation (the sum of base salary and target annual performance bonus) and total target direct compensation (the sum of total target cash compensation and long-term equity compensation) at the median, or 50<sup>th</sup> percentile, of the market data. Total cash compensation based on achievement of stretch performance goals under our performance bonus plan generally is targeted to approximate the 75<sup>th</sup> percentile of the market data. Long-term equity compensation in the form of PSUs and RSUs generally is targeted to approximate the median of the market data. The Committee believes that this competitive positioning is consistent with the goals of the Company's compensation programs, by linking pay to performance and providing top-tier compensation only when the Company achieves superior performance.

**<u>[**TABLE OF CONTENTS**](#iabb2672efea04a1781f060e066a7be4c_7)</u>**

**Executive Incentive Compensation Recoupment Policy**<br>

The Company has an Executive Incentive Compensation Recoupment Policy which covers all executive officers of the Company, as well as the Company's corporate controller. The policy is designed to recoup incentive-based compensation in the event that we are required to prepare an accounting restatement due to our material noncompliance with any financial reporting requirement under the securities laws, and effective October 2, 2023, it was amended and restated to comply with SEC rules under Section 10D-1 of the Exchange Act and the NYSE listing standards.

In addition to requiring the recovery of erroneously awarded incentive-based compensation under the amended and restated policy, our equity award documents provide for forfeiture of awards in cases where a grantee violates a confidentiality, non-competition or non-solicitation covenant or agreement and for recoupment in cases where, following a termination of employment, the Company determines that a termination for cause would have been justified prior to such termination.

**Executive Stock Ownership Guidelines** <br>

To more closely align the interests of our management with those of our shareholders, the Board of Directors has adopted stock ownership guidelines for our executive officers. The guidelines require that each of our executive officers own a minimum number of shares having a value equal to the following:

---

| | |
|:---|:---|
| **Role** | **Minimum Value of Shares** |
| Chief Executive Officer | 6x annual base salary |
| Chief Operating Officer | 4x annual base salary |
| Executive Vice Presidents | 3x annual base salary |
| Senior Vice Presidents | 2x annual base salary |
| Vice Presidents | 1x annual base salary |

---

All shares held by our executives, including unvested RSUs, but not including unearned PSUs or shares underlying unexercised stock options, count toward these guidelines. The guidelines provide for our executives to reach these goals within five years from the date on which the executive is elected (or three years in the case of a promotion). Once an executive has attained the applicable minimum ownership requirement, such executive must maintain at least that level of ownership. If an executive has not satisfied the applicable proportionate minimum stock ownership guideline, the executive must retain an amount equal to 100% of the net shares (i.e., after tax withholding and shares sold to pay the exercise price of options) received as a result of the exercise of stock options or the vesting of PSUs or RSUs. All of our executive officers are in compliance with their current stock ownership guidelines. In addition to our stock ownership guidelines, we believe that our long-term stock-based compensation program properly aligns the interests of our executives with those of our shareholders, and encourages and incentivizes long-term planning and strategic initiatives to enhance shareholder value.

**Federal Income Tax Deductibility of Executive Compensation**<br>

Section 162(m) of the Internal Revenue Code of 1986 (the "Code") imposes a $1.0 million limit on the amount that a publicly held corporation may deduct for compensation paid to its "covered employees." Covered employees include any officer who is a named executive officer in any taxable year beginning after December 31, 2016. Due to the deduction limitation in Section 162(m), compensation paid to our named executive officers in excess of $1.0 million is not deductible. While the Committee considers the deductibility of compensation as one factor in determining executive compensation, the Committee believes that it is in the best interests of our shareholders to maintain flexibility in our approach to executive compensation in order to structure a program that we consider to be the most effective in attracting, motivating and retaining key executives.

**COMPENSATION RISK ASSESSMENT**<br>

The Compensation Committee engaged FW Cook to conduct a comprehensive risk assessment of our incentive-based compensation plans in fiscal year 2025 to assist the Compensation Committee in its compensation risk assessment. In its report to the Compensation Committee, FW Cook determined that our incentive plans were well-aligned with sound compensation design principles and that there were no significant areas of concern from a compensation risk perspective. FW Cook noted that while the compensation plans have evolved over the years to align with market standards, the changes to the plans have not resulted in elevated risk concerns. FW Cook also noted key risk mitigating practices continue to be present, including among other features, robust stock ownership guidelines and a compensation recoupment policy for executive officers and the Company's controller. Based on the Compensation Committee's review and the FW Cook report, the Compensation Committee believes that our compensation programs do not encourage excessive or inappropriate risk-taking on the part of our associates, including our executive and senior officers. The Compensation Committee believes that the design and mix of our compensation programs appropriately encourage our executive and senior officers to focus on the creation of long-term shareholder value. In its review, the Compensation Committee noted the following features:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• executive and senior officer pay mix balances fixed and variable cash compensation, cash and equity, and annual and longer-term incentive compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our executive performance bonus plan includes the following design features which the Compensation Committee believes properly incentivize senior management:

maximum payouts are capped at 188% of target;

payout levels based on achievement of financial metrics generally are calculated on a straight-line interpolation basis between threshold and target levels and between target and maximum levels, rather than providing for significantly different payout levels based on small changes in operating results;

the annual performance bonus is largely based on achievement of multiple financial metrics, rather than a single financial metric;

the annual performance bonus plan includes a weighting for achievement of individual G&Os. In addition, all levels within the organization also include an individual performance multiplier, which is evaluated by the Compensation Committee, which serves to focus management on achievement of strategic business and long-term initiatives;

the Compensation Committee retains discretion to adjust Company financial metrics to account for non-recurring and other similar items; and

the Compensation Committee retains discretion to modify annual bonus payouts otherwise payable under the performance bonus plan where it determines that bonus amounts are not reflective of Company and individual performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• annual non-management bonus plans for corporate, sales and other business functions allocate a lower percentage of variable cash compensation than for management with bonus awards based on subjective assessment of individual performance;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• long-term equity awards constitute a significant portion of executives' and senior officers' compensation, thereby focusing such individuals on enhancing long-term shareholder value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• equity awards for associates provide three-year cliff vesting for PSUs and four- or five-year vesting for RSUs, depending on the position of the associate in question; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• PSUs vest based on Company performance over a three-year period and provide for maximum payouts of 200% of target.

In addition to the design and mix of our compensation programs, to further align our executive officers' interests with our shareholders and mitigate risk relating to our compensation programs, we have adopted an Executive Incentive Compensation Recoupment Policy, which is described in the section entitled "***Compensation Discussion and Analysis*** — ***Executive Incentive Compensation Recoupment Policy***" on page [43](#iabb2672efea04a1781f060e066a7be4c_163) of this Proxy Statement and stock ownership guidelines for all of our executive officers, which is described in the section entitled "***Compensation Discussion and Analysis*** — ***Executive Stock Ownership Guidelines***" on page [43](#iabb2672efea04a1781f060e066a7be4c_166) of this Proxy Statement.

(1)These columns reflect the potential threshold, target and maximum annual performance bonuses payable to such named executive officer under our 2025 annual performance bonus plan. Amounts actually earned in fiscal year 2025 are reported as Non-Equity Incentive Plan Compensation in the Summary Compensation Table. Under our 2025 annual performance bonus plan, bonus awards for 2025 were designed to be based on achievement of two Company financial metrics, each weighted 37.5%, and the remaining 25% was based on the achievement of individual G&Os. In addition, award opportunities were designed to be subject to an individual performance multiplier ranging from 50% to 150%. For additional information, please see "***Compensation Discussion and Analysis*** — ***Fiscal Year 2025 Executive Compensation*** — ***Annual Performance Bonus Plan***" beginning on page [37](#i2745688ba46847c39fcef836d20a238f_33219) of this Proxy Statement.

(2)These columns reflect the potential threshold, target and maximum amounts of PSUs granted in fiscal year 2025 pursuant to the 2023 Omnibus Incentive Plan. These PSUs cliff vest after three years, with payouts ranging from 0% to 200% of target (with straight-line interpolation used for determining payouts with achievement between threshold and target and target and maximum performance levels) based upon our average adjusted return on invested capital from fiscal year 2025 through fiscal year 2027, subject to the grantee's continued employment (with exceptions for termination of employment due to death, disability, retirement and change in control). For additional information, please see "***Compensation Discussion and Analysis*** — ***Fiscal Year 2025 Executive Compensation*** — ***Long-Term Stock-Based Compensation***" beginning on page [39](#i2745688ba46847c39fcef836d20a238f_33250) of this Proxy Statement and "— ***Potential Payments Upon Termination or Change in Control***" beginning on page [51](#iabb2672efea04a1781f060e066a7be4c_199) of this Proxy Statement.

(3)The amounts in this column represent RSUs granted in fiscal year 2025 pursuant to the 2023 Omnibus Incentive Plan. These awards vest 25% on each of the first through fourth anniversaries of the grant date (with exceptions for termination of employment due to death, disability, retirement and change in control). The RSUs granted to our named executive officers have no performance criteria. For additional information, please see "***Compensation Discussion and Analysis*** — ***Fiscal Year 2025 Executive Compensation*** — ***Long-Term Stock-Based Compensation***" beginning on page [39](#i2745688ba46847c39fcef836d20a238f_33250) of this Proxy Statement and the section entitled "— ***Potential Payments Upon Termination or Change in Control***" beginning on page [51](#iabb2672efea04a1781f060e066a7be4c_199) of this Proxy Statement.

(4)The grant date fair value is the amount that we will expense in our consolidated financial statements over the award's vesting schedule. For RSUs and PSUs, fair value is the closing price of a share of our Class A Common Stock as quoted on the NYSE on the date of grant. The closing price of a share of our Class A Common Stock as quoted on the NYSE on November 4, 2024 was $80.52. For PSUs, the fair value is based on the Company achieving a target level of performance. For additional information on the valuation assumptions, please refer to Note 13 to our audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended August 30, 2025.

(5)Ms. Actis-Grande departed the Company on August 8, 2025 (before the end of fiscal year 2025) and, therefore, was not eligible to receive an annual performance bonus under the terms of the award. In accordance with the terms of the RSUs and PSUs, all of her unvested RSUs and PSUs were forfeited upon termination of employment.

Dividends are not paid on unvested RSUs and PSUs; instead, dividend equivalent units accrue on unvested RSUs and PSUs and vest at the same times as the underlying RSUs and PSUs, subject in the case of PSUs to the same performance vesting requirements. The quarterly dividend rate for fiscal year 2025 was $0.85 per share.

**Outstanding Equity Awards at 2025 Fiscal Year-End**<br>

The following table shows the amounts of outstanding stock options, RSU awards and PSU awards previously granted and held by the named executive officers as of August 30, 2025.

The market value of the stock awards is based on the closing price of a share of our Class A Common Stock as of August 29, 2025, the last business day of fiscal year 2025, which was $90.23.

Kristen Actis-Grande departed the Company on August 8, 2025. In accordance with the terms of the RSUs and PSUs, all of her unvested RSUs and PSUs were forfeited upon termination of her employment.

**Pension Benefits and Nonqualified Deferred Compensation**<br>

Our named executive officers do not receive any compensation in the form of pension benefits or nonqualified deferred compensation.

**Potential Payments Upon Termination or Change in Control**<br>

***Change in Control Arrangements***

Each of our named executive officers participates in the MSC Industrial Direct Co., Inc. Executive Change in Control Severance Plan (the "Executive Change in Control Severance Plan"). The Executive Change in Control Severance Plan provides for payment of certain benefits to the named executive officers upon a qualifying termination following a change in control of the Company. In addition to these arrangements, each of our current named executive officers executed a confidentiality, non-solicitation and non-competition agreement under which each of them agreed not to use or disclose any confidential information relating to the Company during employment and after termination. Each of them also agreed not to compete with the Company or to solicit any associates of the Company during such employment and for two years following termination of such employment. All payments under the change in control arrangements are contingent on them complying with the foregoing obligations. The terms of these arrangements are discussed below.

Under the terms of these arrangements, "cause" is generally defined to include (i) the willful and continued failure by the executive to substantially perform applicable duties (other than any such failure resulting from incapacity due to physical or mental illness) after a written demand for substantial performance is delivered to the executive by the Company, (ii) the willful engaging by the executive in conduct which is demonstrably and materially injurious to the Company, monetarily or otherwise, or (iii) the executive's conviction of, or entering a plea of nolo contendere to, a felony. A change in the executive's "circumstances of employment" will generally be deemed to have occurred if there is (a) a material reduction or change in the executive's employment duties or reporting responsibilities, (b) a reduction in the executive's annual base salary, (c) a material diminution in the executive's status, working conditions or other economic benefits, or (d) the Company requiring the executive to be based at any place outside a 30-mile radius from the Company's offices where the executive was based prior to a change in control.

A change in control of the Company will generally be deemed to have occurred under these arrangements if (i) a person or entity, other than members of the Jacobson or Gershwind families, acquires beneficial ownership of 50% or more of the combined voting power of the Company's voting securities, (ii) there is a change in the Board as a result of which the Board members cease to constitute a majority of the Board, (iii) there is a consummation of a merger or consolidation, other than a merger or consolidation that results in our shareholders holding more than 50% of the combined voting power of the voting securities of the surviving entity, (iv) there is a liquidation or dissolution approved by our shareholders, or (v) there is a consummation of a sale of all or substantially all of the Company's assets.

**<u>[**TABLE OF CONTENTS**](#iabb2672efea04a1781f060e066a7be4c_7)</u>**

The Executive Change in Control Severance Plan provides that if, within two years after the occurrence of a change in control of the Company, (i) we terminate the executive's employment other than for cause or (ii) the executive terminates employment following a change in the executive's "circumstances of employment," then we will be obligated to pay the executive a severance payment equal to (a) two times the executive's annual base salary, plus (b) two times the executive's targeted annual cash incentive bonus, plus (c) the pro rata portion of the executive's targeted annual cash performance bonus. In addition, any unvested stock options and stock awards would accelerate. As a condition to receiving the applicable severance payments and benefits, the executive would be required to execute a general release in favor of the Company.

In addition, if the executive's employment is terminated after the occurrence of a change in control as described above, we are obligated to provide the executive with outplacement services for up to six months and a lump sum payment equal to 18 months of healthcare coverage, and the executive is entitled to receive, at our expense, an automobile allowance for the lesser of two years or the remainder of the automobile lease in effect following the termination of such executive's employment.

Under the Executive Change in Control Severance Plan, the amount of severance benefits for these executives would be subject to reduction to the extent that the after-tax payments would be increased as a result of the payments being classified as "excess parachute payments" under Section 280G of the Code.

***Equity Award Plans***

The number of outstanding equity awards held by each named executive officer under the 2015 Omnibus Incentive Plan and the 2023 Omnibus Incentive Plan as of August 30, 2025 is listed above in the Outstanding Equity Awards at 2025 Fiscal Year-End table. The terms of these benefits are described below.

In connection with their long-term incentive awards, the named executive officers are required to sign an agreement containing confidentiality and non-competition provisions designed to protect the Company's confidential and proprietary information and to preserve the Company's competitive advantages.

*2015 Omnibus Incentive Plan and 2023 Omnibus Incentive Plan*

The 2015 Omnibus Incentive Plan and the 2023 Omnibus Incentive Plan are each a "double trigger" plan, meaning that unvested stock options and RSUs vest if there is a change in control of the Company <u>only if</u> both (i) a change in control occurs and (ii) such options or awards are not continued, assumed or substituted in connection with the transaction or if there is a termination of employment without cause (or for executives who participate in the Executive Change in Control Severance Plan, a termination by the executive for good reason) within one year (two years for executives who participate in the Executive Change in Control Severance Plan) following the change in control. In the case of PSUs, if unvested PSUs are not assumed, the PSUs will vest and be earned at the target level of performance, provided that if the change in control occurs after the first full year of performance and the performance level is higher than the target level, the PSUs would vest and be earned at such higher level. If in connection with a change in control the PSUs are assumed, then the PSUs would convert to RSUs based on the target level of performance, provided that if the change in control occurs after the first full year of performance and the performance level is higher than the target level, the PSUs would convert to RSUs at such higher level. In addition, following any change in control, if an associate's employment is terminated by the Company without cause (or for executives who participate in the Executive Change in Control Severance Plan, a termination by the executive for good reason) within one year (two years for executives who participate in the Executive Change in Control Severance Plan) following the change in control, vesting of any converted RSUs would accelerate. A change in control of the Company will be deemed to have occurred for purposes of the 2015 Omnibus Incentive Plan and the 2023 Omnibus Incentive Plan in the same circumstances as described above under the section entitled "— ***Change in Control Arrangements***."

Under the 2015 Omnibus Incentive Plan and the 2023 Omnibus Incentive Plan and awards thereunder, in the event that the employment of a named executive officer is terminated by reason of death, disability or retirement, all unvested stock options held by the named executive officer become immediately exercisable until the first anniversary of such termination or until the stock options expire by their terms, whichever is shorter, and the restrictions on outstanding RSUs shall lapse and the shares underlying such RSUs shall become fully vested. The named executive officer will be deemed to have retired if such named executive officer's employment is terminated without cause, or upon death or disability, on or after age 65, provided the named executive officer has a total of five years of service with the Company. In the case of PSUs, where a participant retires or voluntarily terminates employment or in cases of a termination without cause (other than in the case of a change in control discussed above and other than in the case of a "qualifying termination" as described below under "— ***MSC Executive Severance Plan***") if the participant has reached age 55 and the participant's age plus years of continuous service equals at least 65, the PSUs will pay out on a pro rata basis based on the full number of years of service (rounded down) during the performance period, based on actual performance. If the participant has reached age 65 with at least five full years of service, then the PSUs would pay out fully, based on actual performance. In cases of death or disability, the PSUs would pay out fully, based on actual performance.

***MSC Executive Severance Plan***

The Board adopted, upon the recommendation of the Compensation Committee, the MSC Executive Severance Plan. Under the MSC Executive Severance Plan, Vice Presidents, Senior Vice Presidents and Executive Vice Presidents of the Company are eligible to receive certain severance benefits in the event of a qualifying termination. For purposes of the MSC Executive Severance Plan, a "qualifying termination" means the occurrence of any of (i) the involuntary termination of a participant's employment with the Company as a result of the elimination of such participant's job or position with the Company because of reorganization, job elimination or site closure; (ii) the termination of a participant's employment with the Company upon the participant's failure to accept a material change in the geographic location where such participant is required to primarily perform his services for the Company, such that the distance between the previous geographic location and the new geographic location exceeds 50 miles (one way); or (iii) the termination of a participant's employment with the Company upon the participant's failure to accept a reduction in such participant's base salary of 20% or more.

Severance benefits consist of a severance allowance, a benefits credit payment, a vesting acceleration benefit and, at the discretion of the plan administrator, outplacement services. The severance allowance generally will be (i) 18 months of base pay for Executive Vice Presidents, (ii) 15 months of base pay for Senior Vice Presidents and (iii) 12 months of base pay for Vice Presidents, plus in each case a pro rata bonus (based on 100% of the individual's bonus target prorated for the current fiscal year based on the date of the qualifying termination so long as the qualifying termination date is on or after the first day of MSC's third fiscal quarter). The benefits credit will be an amount equal to the credit provided by the Company toward the cost of the participant's coverage under our healthcare exchange for 18 months in the case of Executive Vice Presidents, 15 months in the case of Senior Vice Presidents and 12 months in the case of Vice Presidents. The vesting acceleration benefit will be the acceleration of equity awards that otherwise would have vested on the next scheduled vesting date after a participant's termination date, except that in the case of PSUs, payouts shall be made at 33-1/3% and based on actual performance, except that if the participant has reached age 55 and the participant's age plus years of continuous service equals at least 65, the PSUs will pay out on a pro rata basis based on the full number of years of service (rounded up) during the performance period, based on actual performance and if the participant has reached age 65 with at least five full years of service, then the PSUs would pay out fully, based on actual performance. Finally, the plan administrator may, in its discretion, provide outplacement services for such duration as the plan administrator may determine.

As a condition of receiving any severance benefit under the MSC Executive Severance Plan, a participant will be required to execute and not revoke a severance and release agreement in favor of the Company in such form and of such content as the plan administrator, in its sole discretion, may require.

Under the MSC Executive Severance Plan, no participant will be entitled to receive severance benefits in the event that the plan administrator determines, in its sole discretion, among other things, that at the time of the participant's qualifying termination, we had cause to terminate the participant due to failure to meet our established performance criteria, the participant's misconduct, or the participant's violation of any applicable Company policy. In addition, if a participant incurs a qualifying termination, and the plan administrator determines, in its sole discretion, that thereafter (i) the participant breached any provision(s) of his severance and release agreement or (ii) the participant breached any provision(s) of any confidentiality, non-compete, non-solicitation, non-disparagement or other restrictive covenant or similar agreement with the Company, any unpaid or unused severance benefits will be immediately forfeited, and the participant will be required to repay to us severance allowance amounts previously paid to such participant.

**Potential Payments Upon Termination or Change in Control Table as of August 29, 2025**<br>

The following table sets forth the estimated amounts that would be payable to each of our named executive officers upon the termination of such named executive officer's employment under certain circumstances or upon a change in control in limited circumstances, assuming that the termination of employment or change in control had occurred on August 29, 2025 (which was the last business day of fiscal year 2025) and based on the price per share of our Class A Common Stock on that date, which was $90.23. The actual amounts payable can only be calculated at the time of the event. None of the named executive officers, except Mr. Clark and Ms. Shacklett, would have been eligible for retirement under the terms of our equity grant agreements as of August 29, 2025, for purposes of the termination provisions under their PSU awards.

Kristen Actis-Grande departed the Company on August 8, 2025 and is not included in the following table.

(1)Unvested stock awards will vest if there is a change in control of the Company only if such awards are not continued, assumed or substituted in connection with the transaction or if there is a termination of employment without cause or by the executive for good reason within two years following the change in control. The estimated values of the PSU and RSU awards listed in this column for each of the named executive officers are based on the closing price of a share of our Class A Common Stock as reported on the NYSE on August 29, 2025, which was $90.23.

(2)Each of the named executive officers executed a confidentiality, non-solicitation and non-competition agreement under which each executive agreed not to use or disclose any confidential information relating to the Company during the executive's employment and after termination. Each executive also agreed not to compete with the Company or to solicit any associates of the Company during such executive's employment and for two years following termination of such executive's employment. All payments under the change in control arrangements are contingent on the executives complying with the foregoing obligations and executing a general release in favor of the Company.

(3)For the named executive officers, the severance amounts in this column reflect estimated amounts payable upon the occurrence of (i) a change in control of the Company and (ii) the termination of employment of the named executive officers within two years following such change in control, (a) by the Company, without cause, or (b) by the executive for good reason. The estimated severance amount listed in this column for each of the named executive officers was calculated using the named executive officer's base salary that was in effect as of August 30, 2025. The estimated values of the PSU and RSU awards listed in this column for each of the named executive officers are based on the closing price of a share of our Class A Common Stock as reported on the NYSE on August 29, 2025, which was $90.23.

(4)The amounts in this column reflect estimated amounts payable upon the death or disability of a named executive officer under the terms of the 2015 Omnibus Incentive Plan and the 2023 Omnibus Incentive Plan and the respective awards thereunder. The estimated values of the accelerated PSU and RSU awards listed in this column for each of the named executive officers are based on the closing price of a share of our Class A Common Stock as reported on the NYSE on August 29, 2025, which was $90.23.

(5)The amounts in this column reflect estimated amounts payable upon the retirement of a named executive officer under the terms of the 2015 Omnibus Incentive Plan and 2023 Omnibus Incentive Plan and the respective awards thereunder. None of our named executive officers are currently eligible for retirement, except that Mr. Clark and Ms. Shacklett qualify as having reached age 55 with their ages and years of continuous service equaling at least 65, for purposes of the termination provisions under their PSU awards. The estimated values of the PSU awards listed in this column are based on the closing price of a share of our Class A Common Stock as reported on the NYSE on August 29, 2025, which was $90.23.

(6)The amounts in this column reflect estimated amounts that would be payable under the MSC Executive Severance Plan, which was amended and restated on March 21, 2023, in the event of a "qualifying termination," (i) assuming that the qualifying termination had occurred on August 30, 2025 and (ii) based on the closing price per share of our Class A Common Stock on August 29, 2025, which was $90.23. Mr. Gershwind is not a participant in the MSC Executive Severance Plan. The estimated severance amount listed in this column for each of the named executive officers (other than Mr. Gershwind) was calculated using the named executive officer's base salary that was in effect as of August 30, 2025. Severance amounts and medical benefits would be payable in equal installments in accordance with the Company's normal payroll practices over the applicable period of either 12, 15 or 18 months. As described above under the section entitled "—Potential Payments Upon Termination or Change in Control — MSC Executive Severance Plan," the accelerated stock options and RSU and PSU awards listed in this column consist of awards that otherwise would have vested on the next scheduled vesting date after the named executive officer's qualifying termination, except that in the case of PSUs, payouts shall be made at 33-1/3% and based on actual performance, with the exceptions of Mr. Clark and Ms. Shacklett who meet the definition of retirement eligible per the PSU award agreements. The PSUs in this column for Mr. Clark and Ms. Shacklett are calculated on a pro rata basis based on full number of years of service (rounded up) during the performance period and based on actual performance as described above under the section entitled "Executive Severance Plan." The estimated values of the accelerated RSU awards listed in this column are based on the closing price of a share of our Class A Common Stock as reported on the NYSE on August 29, 2025, which was $90.23. The estimated values of the accelerated PSU awards listed in this column are based on the number of adjusted shares per the MSC Executive Severance Plan and the closing price of a share of our Class A Common Stock as reported on the NYSE on August 29, 2025, which was $90.23. Values for PSUs which had a performance end date of August 30, 2025 are based on actual performance, 0%, and values for PSUs which have a future performance end date are based on target performance. As a condition of receiving any severance benefit under the MSC Executive Severance Plan, a participant will be required to execute and not revoke a severance and release agreement in favor of the Company in such form and of such content as the plan administrator, in its sole discretion, may require. In addition, no participant will be entitled to receive severance benefits in the event that the plan administrator determines, in its sole discretion, among other things, that at the time of the participant's qualifying termination, the Company had cause to terminate the participant due to failure to meet Company-established performance criteria, the participant's misconduct, or the participant's violation of any applicable Company policy.

**CEO PAY RATIO**<br>

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our median associate and the annual total compensation of our Chief Executive Officer.

For fiscal year 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the annual total compensation of our median associate was $66,908; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the annual total compensation of our Chief Executive Officer, as reported in the Summary Compensation Table appearing under "***Executive Compensation***," was $5,873,837

Based on this information, the ratio of the annual total compensation of our Chief Executive Officer to the annual total compensation of our median associate for fiscal year 2025 was 88:1.

The SEC rules permit companies to identify the median paid associate once every three years as long as there has been no change in the Company's associate population or compensation arrangements that significantly impacts the pay ratio disclosure. We determined that there were no changes during fiscal year 2025 that would significantly impact our pay ratio disclosure. Therefore, the Company used the same median associate identified in fiscal year 2024 to determine the median annual total compensation of all associates (excluding our Chief Executive Officer) and to calculate the pay ratio for the 2025 fiscal year.

To identify the median of the annual total compensation of all of our associates for our fiscal year 2025 CEO pay ratio, as well as to determine the annual total compensation of our median associate, the methodology and the material assumptions, adjustments and estimates that we used were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We selected August 31, 2024 as the date for identifying our median associate. We determined that, as of August 31, 2024, our associate population, which includes our U.K., Canada and Mexico operations, consisted of approximately 7,000 associates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our associate population data described above excludes approximately 43 associates of KAR Industrial, Inc., which was acquired in January 2024, and excludes approximately 30 and 27 associates of ApTex, Inc. and Premier Tool Grinding, Inc., respectively, which we acquired in June 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We identified our median associate based on the total cash compensation earned for fiscal year 2024. Total cash compensation earned for fiscal year 2024 included base salary, bonus and incentives, commissions and overtime earned for such period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For purposes of identifying the median associate, we applied the following exchange rates at August 31, 2024: (i) 1 British pound to 1.31 U.S. dollars, (ii) 1 Canadian dollar to 0.74 U.S. dollars and (iii) 1 Mexican peso to 0.05 U.S. dollars.

We determined our median associate's annual total compensation for fiscal year 2025 in the same manner that we determine the annual total compensation of our named executive officers for purposes of the Summary Compensation Table appearing under "***Executive Compensation.***" The annual total compensation of our median associate for fiscal year 2025 was determined to be $66,908, which was then compared to the annual total compensation of our Chief Executive Officer, as reported in the Summary Compensation Table appearing under "***Executive Compensation***."

The SEC's rules for identifying the median compensated associate and calculating the pay ratio based on that associate's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their associate populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different associate populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

We believe this pay ratio is a reasonable estimate calculated in a manner consistent with applicable rules of the SEC. This information is being provided for compliance purposes. Neither the Compensation Committee nor management of the Company used the pay ratio measure in making compensation decisions for fiscal year 2025.

**PAY VERSUS PERFORMANCE**

(4)Total shareholder return ("TSR") is calculated based on the value of an initial fixed investment of $100 on August 29, 2020, assuming reinvestment of dividends. The peer group TSR represents TSR of the Dow Jones U.S. Industrial Supplier Index, which is the peer group used by the Company for purposes of Item 201(e) of SEC Regulation S-K in the Company's Annual Report on Form 10-K for the fiscal year ended August 30, 2025.

(5)Adjusted Operating Margin and Organic Revenue Growth (ADS) are non-GAAP financial measures. See Appendix A to this Proxy Statement for definitions and reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures. We are including Organic Revenue Growth (ADS) in the table because ADS is a key driver of incentive compensation and is an important driver of value creation for our shareholders.&nbsp;&nbsp;&nbsp;&nbsp;

(6)We determined Adjusted Operating Margin to be the most important financial performance measure used to link Company performance to "compensation actually paid" to our CEO and other NEOs in 2025. This performance measure may not have been the most important financial performance measure for years 2024, 2023 and 2022 and we may determine a different financial performance measure to be the most important financial performance measure in future years.

**ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION** <br>**(PROPOSAL NO. 3)**<br>

As required by Section 14A of the Exchange Act, this proposal, commonly known as a "say-on-pay" proposal, gives our shareholders the opportunity to vote to approve or not approve, on an advisory basis, the compensation of our named executive officers, which is described in the "***Compensation Discussion and Analysis***" and "***Executive Compensation***" sections of this Proxy Statement. This vote is not intended to address any specific item or element of compensation or the compensation of any particular officer, but rather the overall compensation of our named executive officers and the philosophy, principles and policies used to determine compensation.

Shareholders were most recently asked to approve the compensation of our named executive officers at the Company's 2025 Annual Meeting of Shareholders, and shareholders approved our named executive officer compensation with more than 98% of the votes cast in favor. At the Company's 2024 Annual Meeting of Shareholders, we asked shareholders to indicate whether future advisory say-on-pay votes should occur every one, two or three years, with the Board recommending an annual advisory vote. Because the Board views it as a good corporate governance practice, and because at the Company's 2024 Annual Meeting of Shareholders a majority of the votes cast were in favor of an annual advisory say-on-pay vote, the Company currently intends to include an advisory say-on-pay vote in its proxy materials on an annual basis until the next required advisory vote on the frequency of future advisory say-on-pay votes, which will occur no later than the Company's 2030 Annual Meeting of Shareholders. Accordingly, the next advisory say-on-pay vote is expected to be held at the Company's 2027 Annual Meeting of Shareholders.

As described in greater detail in the section entitled "***Compensation Discussion and Analysis***," our key compensation goals are to: create a performance driven culture based on personal accountability by linking rewards to Company and individual performance; provide a market competitive compensation opportunity to enable the Company to attract, retain and motivate highly talented associates; and recruit, retain and motivate highly talented executives, align our executives' interests with those of our shareholders and provide performance-based compensation that appropriately rewards our executives. Our compensation programs include a number of key features designed to accomplish these goals.

The Board urges our shareholders to read the section entitled "***Compensation Discussion and Analysis***," which describes in detail how our executive compensation practices operate and are designed to achieve our key compensation goals, as well as the Summary Compensation Table and other related compensation tables and narrative discussion appearing under the section entitled "***Executive Compensation***," which provide detailed information about the compensation of our named executive officers. Based on Company and individual performance, the Compensation Committee believes that compensation levels for fiscal year 2025 were appropriate and consistent with the philosophy and objectives of the Company's executive compensation programs.

Accordingly, we are asking shareholders to vote, on an advisory basis, "**FOR**" the following resolution at the Annual Meeting:

RESOLVED, that the Company's shareholders hereby approve the compensation of the named executive officers, as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC, including the "***Compensation Discussion and Analysis***" section, the compensation tables and the related narrative discussion.

This vote is advisory, which means that the shareholder vote on this proposal will not be binding on the Company, the Compensation Committee or the Board. However, the Compensation Committee and the Board value the opinions of the Company's shareholders and will carefully consider the outcome of the vote when making future compensation decisions for the named executive officers of the Company.

**THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT. UNLESS OTHERWISE SPECIFIED, PROXIES WILL BE VOTED "FOR" THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT.**

**APPROVAL OF AMENDMENT NO. 1 to AMENDED AND RESTATED ASSOCIATE STOCK PURCHASE PLAN (PROPOSAL NO. 4)**<br>

Our Board has adopted, subject to shareholder approval, an amendment to our Amended and Restated Associate Stock Purchase Plan, which we refer to below as Amendment No.1 and the Stock Purchase Plan, respectively. We are asking our shareholders to approve Amendment No. 1 to: (i) increase the number of shares available for sale thereunder by 300,000 shares of our Class A common stock to an aggregate of 2,150,000 shares of our Class A common and (ii) extend the term of the plan by an additional five years, through October 31, 2035. The text of Amendment No. 1 is attached to this proxy statement as Appendix B.

Approval of Amendment No. 1 will require the affirmative vote of at least a majority of the votes cast in person or by proxy at the annual meeting, assuming the presence of a quorum. For this Proposal, abstentions will be counted as votes cast and therefore will have the same effect as votes cast against this Proposal. As further discussed in the section titled "What is a broker non-vote" on page [72](#i1ab0953fc5874284a3a189460b8d32e7_16356) of this proxy statement, if you own shares through a bank, broker or other holder of record, you must instruct your bank, broker or other holder of record how to vote in order for them to vote your shares so that your vote can be counted on this Proposal.

If shareholders approve Amendment No. 1, it will become effective as of that date. If shareholders do not approve Amendment No. 1, the Company will continue to have the authority to issue shares under the Stock Purchase Plan with its existing terms and shares currently available.

***Reasons for the Amendment***

The Compensation Committee, in consultation with our Board and senior management, has determined that the ability of our associates to purchase shares of our Class A common stock under the Stock Purchase Plan helps achieve our short and long-term compensation objectives. However, as of November 24, 2025, only 110,986 shares of our Class A common stock were available for future sale under the Stock Purchase Plan. Accordingly, on December 2, 2025, our Board adopted Amendment No. 1 to the Stock Purchase Plan which will be effective upon shareholder approval. Amendment No. 1 (i) increases the authorized shares of the Class A common stock of the Company reserved for sale under the Stock Purchase Plan by 300,000 shares to 2,150,000 shares and (ii) extends the term of the Stock Purchase Plan for an additional five years, through October 31, 2035. If our shareholders do not approve Amendment No. 1, we expect that we will exhaust our remaining share reserve under the Stock Purchase Plan during our fiscal year 2027, and we will then be unable to use the Stock Purchase Plan to provide eligible associates with the opportunity to purchase shares of our Class A common stock under the Stock Purchase Plan. After giving effect to Amendment No. 1, the total number of shares of Class A common stock of the Company remaining available for issuance under the Stock Purchase Plan will be approximately 410,986 shares.

***Purpose of the Stock Purchase Plan***

The purpose of the Stock Purchase Plan is to provide our associates with an opportunity to purchase shares of our Class A common stock through payroll deductions. We intend that the Stock Purchase Plan qualify as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"). Accordingly, the provisions of the Stock Purchase Plan are to be construed so as to extend and limit participation in a manner consistent with the requirements of that section of the Code.

***Plan History***

Our Board adopted the Stock Purchase Plan on May 4, 1998 and our shareholders approved the plan at the 1999 annual meeting of shareholders. The initial share reserve of the Stock Purchase Plan was 500,000 shares of our Class A common stock, which was increased by our shareholders on January 4, 2005, by 300,000 shares, to a total of 800,000 shares of our Class A common stock.

On October 29, 2003, our Board adopted amendments to the Stock Purchase Plan, approved by our shareholders on January 6, 2004, to:

&nbsp;&nbsp;&nbsp;&nbsp;• modify the price as which shares of our Class A common stock could be purchased under the plan;

***Administration***

The Stock Purchase Plan is administered by the Compensation Committee.

***Eligibility and Extent of Participation***

Each of our associates who is customarily employed for at least 20 hours per week and for more than five months in a calendar year is eligible to participate in the Stock Purchase Plan, commencing on the first day of the month following the completion of both the month in which he or she was hired and the next full calendar month. Participation in the Stock Purchase Plan is further subject to certain limitations imposed by Section 423(b) of the Code. As of November 24, 2025, eight executive officers and approximately 6,500 other associates were eligible to participate in the Stock Purchase Plan.

An associate may become a participant in the Stock Purchase Plan by completing a subscription agreement authorizing payroll deductions on the form provided by us and filing it with the human resources department of the company prior to the first day of the offering period with respect to which it is to be effective.

Payroll deductions will be equal to the percentage of eligible compensation (not to exceed 15%) specified by the participant. Once enrolled, a participant remains enrolled in each subsequent offering period of the Stock Purchase Plan at the designated payroll deduction unless the participant withdraws by providing us with written notice of withdrawal or files a new subscription agreement prior to the applicable offering date changing the associate's designated payroll deduction.

***Purchase of Shares***

The maximum number of shares of our Class A common stock a participant may purchase during each offering period may not exceed 5,000 shares, subject to certain limitations set forth in the Code and the availability of shares under the Stock Purchase Plan.

Unless a participant withdraws from the Stock Purchase Plan during an offering period, his or her option to purchase shares will be exercised automatically at each exercise date (the last business day of the offering period), and the maximum number of full and fractional shares subject to the option will be purchased at the applicable purchase price with the accumulated payroll deductions in his or her account. A participant's option to purchase shares under the Stock Purchase Plan may be exercised only by the participant.

***Offering Periods***

Options are granted under the Stock Purchase Plan to purchase shares of our Class A common stock in consecutive three-month offering periods, with a new offering period commencing on each November 1, February 1, May 1 and August 1, unless otherwise determined by our Board.

***Purchase Price***

The purchase price per share at which shares of our Class A common stock are sold under the Stock Purchase Plan is 90% of the fair market value of our Class A common stock as of the date options are exercised in each period to purchase shares of the company. Under our Stock Purchase Plan, our Board may, without shareholder approval, change the discount under the plan, from time to time, provided that the purchase price may not be less than the lesser of (a) 85% of the fair market value of our Class A common stock on the first day of an offering period, and (b) 85% of the fair market value of our Class A common stock on the exercise date.

***Valuation***

The fair market value of our Class A common stock on any relevant date under our Stock Purchase Plan is the closing sale price of a share of our Class A common stock on the New York Stock Exchange on such date. If there is no sale of our Class A common stock on the New York Stock Exchange on such date, the fair market value of the shares will be the average of the bid and asked prices on the exchange on such date. If our Class A common stock is no longer traded on the New York Stock Exchange, the fair market value will be determined by the plan administrator in its reasonable

discretion. As of December 4, 2025, the closing price of our Class A common stock on the New York Stock Exchange was $82.44.

***Transferability***

Neither contributions credited to an associate's account under the Stock Purchase Plan nor any option to purchase shares pursuant to the plan may be assigned in any way, except that contributions credited to an associate's account may be transferred to a designated beneficiary upon such associate's death.

Any shares acquired by a participant pursuant to the plan may not be assigned, transferred, pledged or otherwise disposed of in any way by the participant for a period of 45 days (or such other longer or shorter time period as may be established by our Board in its sole discretion) following the date on which the participant acquired such shares as a result of the exercise of such participant's option.

***Adjustments***

In the event of any stock dividend, stock split, combination or exchange of shares, recapitalization or other change in the capital structure of the company, corporate separation or division of the company (including a split-up, spin-off, split-off or other distribution to our shareholders other than a normal or special cash dividend), sale by the company of all or a substantial portion of its assets, reorganization, rights offering, partial or complete liquidation, merger or consolidation in which the company is the surviving corporation, or any other corporate transaction or other event involving the company and having an effect similar to any of the foregoing, our Board shall make such substitution or adjustments in (i) the number and kind of shares made available for sale under the Stock Purchase Plan, (ii) the number and kind of shares or other property, including cash, subject to outstanding options under the Stock Purchase Plan, (iii) the purchase price for outstanding options under the Stock Purchase Plan and (iv) other characteristics or terms of the options, as necessary or appropriate to equitably reflect such corporate transaction or other event and to prevent dilution or enlargement of participants' rights under the Stock Purchase Plan. In the event of the dissolution or liquidation of the company, or a merger, reorganization or consolidation in which the company is not the surviving corporation, our Board, in its discretion, may accelerate the exercise of each option and/or terminate the same within a reasonable time thereafter.

***Withdrawal; Termination of Employment***

A participant may withdraw all, but not less than all, of the payroll deductions credited to his or her account under the Stock Purchase Plan at any time prior to an exercise date by giving written notice to us on a form provided for such purpose. If the participant withdraws from the Stock Purchase Plan during an offering period, all of the participant's payroll deductions credited to his or her account will be paid to the participant as soon as practicable after receipt of the notice of withdrawal and his or her option for the current offering period will be automatically canceled, and no further payroll deductions for the purchase of shares will be made during such offering period or subsequent offering periods, except pursuant to a new subscription agreement filed in accordance with the Stock Purchase Plan.

Upon the termination of a participant's continuous status as an associate prior to an exercise date of an offering period for any reason, including retirement or death, he or she will be deemed to have elected to withdraw from the Stock Purchase Plan, the payroll deductions accumulated in his or her account will be returned to him or her as soon as practicable after such termination or, in the case of death, to his or her designated beneficiary, and his or her option to purchase shares will be automatically canceled.

All payroll deductions received or held by us under the Stock Purchase Plan may be used by us for any corporate purpose, and we are not obligated to segregate such payroll deductions.

***Duration and Modification***

The Stock Purchase Plan is set to expire on October 31, 2030 in accordance with its terms. However, on December 2, 2025, our Board approved an amendment to extend the term of the plan by an additional five years, through October 31, 2025. Our Board may at any time and for any reason terminate or amend the plan as it may deem advisable. However, we must obtain shareholder approval of any amendment to the Stock Purchase Plan to the extent that such approval is necessary to comply with Section 423 of the Code or any other applicable rules and regulations.

***Federal Income Tax Consequences***

The following is a general summary as of the date of this proxy statement of the U.S. federal income tax consequences to the company and the associates participating in the Stock Purchase Plan. Federal tax laws may change and the federal, state and local tax consequences for any participating associate will depend upon his or her individual circumstances. Each participating associate has been and is encouraged to seek the advice of a qualified tax adviser regarding the tax consequences of participation in the Stock Purchase Plan. The following discussion relates only to the federal income tax consequences of plan participation. It does not, for example, describe state or local income tax consequences in the United States, employment tax or social insurance consequences, nor any income or other tax consequences for participants who are subject to tax in countries other than the United States.

The Stock Purchase Plan, and the right of participants to make purchases thereunder, is intended to qualify under the provisions of Sections 421 and 423 of the Code. Participant contributions to the Stock Purchase Plan that are deducted from compensation constitute taxable wages to the participant for which we are generally entitled to a tax deduction.

Generally, no income will be taxable to a participant when an option is exercised and the shares are purchased. Upon disposition of the shares, the participant will be subject to tax and the amount of the tax will depend on the length of time the participant held the shares. If the participant sells or disposes of the shares no earlier than two years after the beginning of an offering period and one year from the date the shares are purchased (a "qualifying disposition") then in the year of the qualifying disposition, the participant (or the participant's estate in the event of death) must recognize ordinary compensation income equal to the lesser of (a) the excess of the fair market value of the shares as of the beginning of the offering period over the purchase price (determined as of the beginning of the offering period) and (b) the excess of the amount realized upon disposition of the shares over the purchase price. Any additional gain or loss recognized on the disposition of the shares will be long-term capital gain or loss. We will not be entitled to an income tax deduction with respect to such disposition.

If the participant sells or disposes of the shares before the end of the above-described holding period (a "disqualifying disposition") then in the year of the disqualifying disposition, the participant must recognize as ordinary compensation income an amount equal to the excess of the fair market value of the shares on the date the shares were purchased over the purchase price, and the company will be entitled to an income tax deduction for the taxable year in which such disposition occurs equal to the amount of such excess. Any additional gain or loss recognized on the disposition of the shares will be short or long-term capital gain or loss to the participant, depending upon the length of time that the participant holds the stock after the date the shares were purchased.

***Number of Shares Purchased by Certain Individuals and Groups***

The following table sets forth the number of shares of our Class A common stock that were purchased under the Stock Purchase Plan from the date of the inception of the plan through November 24, 2025, for each of our named executive officers, all current executive officers as a group, and all other associates who participated in the Stock Purchase Plan as a group.

***New Plan Benefits Under the Stock Purchase Plan***

No options have been granted, and no shares have been issued, on the basis of the 300,000 share increase that we are requesting in this Proposal. The total number of shares to be received by or allocated to eligible associates under the Stock Purchase Plan cannot be determined at this time because the amount of contributions set aside to purchase shares of our Class A common stock under the plan is within the discretion of each plan participant and the amount of shares which will be purchased is dependent on the fair market value of our Class A common stock on various future dates. Non-executive directors are not eligible to participate in the Stock Purchase Plan.

**SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT**<br>

The information set forth in the table below is based on information furnished as of the close of business on November 24, 2025, except as otherwise noted, regarding the beneficial ownership of our Class A Common Stock by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each shareholder known to us to be the beneficial owner of more than 5% of our Class A Common Stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each director and nominee for director of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each of our named executive officers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all directors and executive officers as a group.

Beneficial ownership is determined in accordance with the rules of the SEC that deem shares to be beneficially owned by any person who has or shares voting or investment power with respect to such shares. In computing the number of shares of Class A Common Stock beneficially owned by a person and the ownership percentage of such person, shares of Class A Common Stock deemed outstanding include (i) RSUs and performance share units that are currently vested or vest within 60 days of November 24, 2025 and (ii) shares of Class A Common Stock that were deferred under our Board of Directors Deferred Compensation Plan that can be acquired at the elective termination of service by the applicable director. However, these shares or units are not deemed outstanding for the purpose of computing the ownership percentage of any other person. The ownership percentage is based on 55,791,582 shares of our Class A Common Stock outstanding as of the close of business on November 24, 2025. Except as otherwise indicated in the footnotes below, the persons listed in the table below have advised us that they have sole voting and investment power with respect to the shares listed as beneficially owned by them. Unless otherwise indicated in the footnotes below, the address for each of the beneficial owners is c/o MSC Industrial Direct Co., Inc., 515 Broadhollow Road, Suite 1000, Melville, New York 11747. All fractional shares reported in the table below have been rounded to the nearest whole share.

***What is a shareholder of record?***

You are a shareholder of record if you are registered as a shareholder with our transfer agent, Computershare Trust Company, N.A.

***What is a beneficial shareholder?***

You are a beneficial shareholder if a bank, broker or similar organization holds your shares in its name for your benefit. This form of ownership is often called ownership in "street name," since your name does not appear in our records. If you are a beneficial shareholder, you may vote by following the voting instructions provided by your bank, broker or other nominee included with your proxy materials or with the instructions on how to access the proxy materials electronically.

***What is a broker non-vote?***

If you hold shares beneficially in street name and you do not provide the organization that holds your shares with voting instructions, then your shares could constitute "broker non-votes." Generally, broker non-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and the beneficial owner does not provide instructions.

If you are a beneficial owner whose shares are held in the name of a broker, and you do not provide your broker with voting instructions, the broker has the authority to vote your shares for or against certain "routine" matters. The proposal to ratify the appointment of EY to serve as our independent registered public accounting firm for fiscal year 2026 is the only routine matter being considered at the Annual Meeting.

We encourage you to provide instructions to your bank, broker or other nominee so that your shares may be voted. If you do not provide instructions to your bank, broker or other nominee, your shares will not be voted in the election of directors, on the advisory vote to approve the compensation of our named executive officers or the approval of Amendment No. 1 to our Associate Stock Purchase Plan.

***What is a quorum?***

A quorum is the minimum number of shares required to hold a shareholders meeting. Under New York law and our Third Amended and Restated By-Laws, the presence, in person or by proxy, of the holders of a majority of the shares of our Class A Common Stock that are entitled to vote is necessary to constitute a quorum at the Annual Meeting.

***What is the vote required for each proposal?***

The election of each nominee for director, the ratification of the appointment of EY to serve as our independent registered public accounting firm for fiscal year 2026, the approval, on an advisory basis, of the compensation of our named executive officers and the approval of Amendment No. 1 to our Associate Stock Purchase Plan each requires the affirmative vote of a majority of the votes cast in person or by proxy at the Annual Meeting. Abstentions will not affect the outcome of any matter being voted on at the Annual Meeting, assuming that a quorum is obtained. Broker non-votes are not counted for any purpose in determining whether a matter has been approved, but, along with abstentions, are considered present and entitled to vote for purposes of determining a quorum for the Annual Meeting.

***Can I ask questions if I participate in the live audio webcast of the Annual Meeting?***

Shareholders as of the close of business on the record date who participate in the live audio webcast of the Annual Meeting will have an opportunity to submit questions live via the Internet during a designated portion of the meeting. Shareholders must have available their 16-digit control number included on their Notice of Internet Availability of Proxy Materials or proxy card or the instructions that they receive by e-mail. If you are a beneficial owner and you do not have a control number, you may contact your bank, broker or other nominee to obtain a control number.

***What will happen if another matter properly comes before the Annual Meeting?***

The Board of Directors does not intend to bring any matter before the Annual Meeting except as specifically indicated in the accompanying notice and these proxy materials, nor does the Board know of any matter that anyone else proposes to present for action at the meeting. However, if any other matters are properly presented at the Annual Meeting for a vote, the enclosed proxy card confers discretionary authority to the proxy holders to vote the shares represented by proxy as to those matters.

***If I plan to participate in the live audio webcast of the Annual Meeting, should I still vote by proxy?***

All shareholders are cordially invited to participate in the live audio webcast of the Annual Meeting at *www.virtualshareholdermeeting.com/MSM2026*. To ensure your representation at the Annual Meeting, you are urged to vote via the Internet, by telephone or by completing, signing, dating and mailing the enclosed proxy card as promptly as possible. If you participate in the live audio webcast of the Annual Meeting, you may vote your shares online during the meeting even though you have submitted proxies or authorized a proxy to vote online. You will need the 16-digit control number included on your Notice of Internet Availability of Proxy Materials or proxy card or the instructions that you receive

by e-mail in order to vote your shares online during the Annual Meeting. If you are a beneficial owner and you do not have a control number, you may contact your bank, broker or other nominee to obtain a control number or voting instructions.

***Who pays the cost for the solicitation of proxies?***

We will pay any expenses for the solicitation of proxies for the Annual Meeting. Upon request, we will reimburse brokers, dealers, banks and trustees, or their nominees, for reasonable expenses that they incur in forwarding material to the beneficial owners of shares of our Class A Common Stock and obtaining their proxies. In addition to soliciting proxies by mail and the Internet, certain of the Company's directors, officers and associates, without additional compensation may solicit proxies personally or by telephone, facsimile and email.

***How can I revoke my proxy or change my vote?***

Shareholders of record may revoke their proxy or change their vote at any time prior to the taking of the vote at the Annual Meeting by (i) submitting a written notice of revocation to our Vice President, General Counsel and Corporate Secretary at MSC Industrial Direct Co., Inc., 515 Broadhollow Road, Suite 1000, Melville, New York 11747; (ii) delivering a proxy bearing a later date (either in writing, by telephone or via the Internet) and until the applicable deadline for each method of voting specified in the Notice of Internet Availability of Proxy Materials or proxy card; or (iii) participating in the meeting via live audio webcast and voting online during the meeting prior to the closing of the polls. Participating in the Annual Meeting will not cause your previously granted proxy to be revoked unless you vote online during the meeting prior to the closing of the polls. For all methods of voting, the last vote cast will supersede all previous votes.

Beneficial shareholders may revoke or change their voting instructions by participating in the Annual Meeting via live audio webcast and voting online during the meeting prior to the closing of the polls or by following the instructions provided by their bank, broker or other nominee. If you are a beneficial shareholder and do not have your control number, you must contact your bank, broker or other nominee for instructions on how to revoke or change your voting instructions.

***How may I obtain a separate set of proxy materials or request a single set for my household?***

For registered shareholders who receive paper copies of this Proxy Statement, copies of our 2025 Annual Report to Shareholders are being mailed simultaneously with this Proxy Statement. All other registered shareholders will receive a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy materials and annual report online and how to request paper copies of our proxy materials and annual report. If you are a registered shareholder and want to save us the cost of mailing more than one copy of our proxy materials and annual report or notice of internet availability of proxy materials, as applicable, to the same address, we will discontinue, at your request to the Senior Vice President, General Counsel and Corporate Secretary of the Company, mailing the duplicate copy to the account or accounts you select. Beneficial owners sharing an address who are receiving multiple copies of proxy materials and annual reports or notices of internet availability of proxy materials, as applicable, and who wish to receive a single copy of such materials in the future, will need to contact their bank, broker or other nominee to request that only a single copy of each document be mailed to all shareholders at the shared address.

If you are the beneficial owner, but not the record holder, of shares of our Class A Common Stock, your bank, broker or other nominee may deliver only one copy of this Proxy Statement and our 2025 Annual Report to Shareholders or instructions on how to access the proxy materials electronically, as applicable, to multiple shareholders who share an address, unless that nominee has received contrary instructions from one or more of the shareholders. If you are a beneficial holder and wish to receive multiple copies of such materials in the future, you will need to contact your bank, broker or other nominee to request multiple copies.

We will deliver promptly, upon written or oral request, a separate copy of this Proxy Statement and our 2025 Annual Report to Shareholders or the Notice of Internet Availability of Proxy Materials, as applicable, to any registered shareholder at a shared address to which a single copy of the document or documents was delivered. A registered shareholder who wishes to receive a separate copy of the proxy statement and the annual report to shareholders or the notice of internet availability of proxy materials, as applicable, now or in the future, should submit this request by writing to Senior Vice President, General Counsel and Corporate Secretary, MSC Industrial Direct Co., Inc., 515 Broadhollow Road, Suite 1000, Melville, New York 11747, or calling (516) 812-2000.

***What is the address of your principal executive offices?***

The mailing address of our principal executive office is 515 Broadhollow Road, Suite 1000, Melville, New York 11747. We also maintain a co-located headquarters at 525 Harbour Place Drive, Davidson, North Carolina 28036.
