ABOUT THE MEETING

What is the date, time and place of the annual meeting?

The Beacon Roofing Supply, Inc. 2021 Annual Meeting of Shareholders will be held on Friday, February 19, 2021, beginning at 8:00 a.m., local time, at Beacon’s corporate headquarters, 505 Huntmar Park Drive, Herndon, VA 20170.

What is the purpose of the annual meeting?

At the annual meeting, shareholders will act upon the matters outlined in the notice of meeting on the cover page of this proxy statement, consisting of 1) election of directors; 2) ratification of the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2021; 3) approval of the compensation of our named executive officers on a non-binding, advisory basis; and 4) any other matters that properly come before the meeting.

Who is entitled to vote at the meeting?

Shareholders of record of our common stock and our Series A Cumulative Participating Preferred Stock (the “Preferred Stock”) at the close of business on December 22, 2020, the record date for the meeting, are entitled to receive notice of and to participate in the annual meeting. If you were a shareholder of record on that date, you will be entitled to vote all of the shares you held on that date at the meeting, or any postponement(s) or adjournment(s) of the meeting. As of the record date, there were 69,393,531 shares of common stock outstanding, all of which are entitled to be voted at the annual meeting. In addition, as of the record date, there were 400,000 shares of Preferred Stock outstanding, all of which are entitled to be voted at the annual meeting. The Preferred Stock is entitled to vote together with the common stock as a single class on each matter to come before the annual meeting, with a number of votes based on the number of shares of common stock into which the Preferred Stock is convertible as of the record date. Accordingly, the 400,000 shares of preferred stock are entitled to a total of 9,694,619 votes. As a result, a total of 79,088,150 votes are eligible to be cast at the annual meeting based on the number of outstanding shares of common stock and Preferred Stock as of the record date.

A list of our shareholders will be available at our headquarters at 505 Huntmar Park Drive, Suite 300, Herndon, Virginia 20170 for a period of ten days prior to the annual meeting and at the annual meeting itself for examination by any shareholder.

What are the voting rights of the holders of our common stock and Preferred Stock?

Holders of common stock are entitled to one vote per share on each matter that is submitted to shareholders for approval. The holder of the Preferred Stock is entitled to an aggregate of 9,694,619 votes on each matter submitted to the shareholders for approval, based on the aggregate number of shares of common stock into which the Preferred Stock is convertible as of the record date.

Are there any requirements on how the holder of Preferred Stock must vote?

Pursuant to the terms of the investment agreement described under “Certain Relationships and Related Transactions,” the holder of the Preferred Stock has agreed to vote in favor of each director nominated and recommended by the Board of Directors for election at the annual meeting. The holder is entitled to vote in its discretion on the other proposals described in this proxy statement.

Who can attend the meeting?

All of our shareholders as of the record date, or their duly appointed proxies, may attend the meeting. In light of the ongoing COVID-19 pandemic, no additional guests may attend. Please also note that if you hold your shares in “street name” (that is, through a broker or other nominee), you will need to bring a copy of a brokerage statement reflecting your stock ownership as of the record date.

In light of the ongoing COVID-19 pandemic, the meeting will be conducted in compliance with limitations on public gatherings mandated by state and local authorities and other preventive measures recommended by public health experts. These measures are expected to include conducting health screenings for persons seeking entry to the meeting, enforcing optimal social distancing guidelines for all attendees, and requiring all attendees to wear masks. We must reserve the right to deny admission to the meeting for persons exhibiting symptoms or behavior that could place our shareholders, employees or facilities at risk. We strongly urge shareholders to vote by proxy over the Internet, by telephone, or by signing, dating, and returning the enclosed proxy card in the enclosed pre-addressed envelope as promptly as possible. Submitting a proxy will not prevent you from voting in person, but it will help to secure a quorum, avoid added solicitation costs, and protect the health and safety of our employees, advisors and other shareholders. Information on how to submit a proxy to vote your shares in advance of the meeting is discussed below.

What constitutes a quorum?

The presence at the meeting, in person or by proxy, of the holders of common stock and Preferred Stock representing a majority of the combined voting power of the outstanding shares of stock on the record date will constitute a quorum, permitting the meeting to conduct its business.

1

What vote is required to approve each item?

The election of the eleven director nominees named in this proxy statement requires the affirmative vote of shares of common stock and Preferred Stock, voting together as a single class, representing a plurality of the votes cast for such election at the annual meeting. This means that the eleven nominees will be elected if they receive more “for” votes than any other person. “Withhold” votes and broker non-votes are not considered votes cast for the foregoing purpose and will have no effect on the election of the nominees.

Ratification of the selection of Ernst & Young LLP and approval of the compensation of our named executive officers each requires the affirmative vote of shares of common stock and Preferred Stock, voting together as a single class, representing a majority of votes cast on such proposal at the annual meeting (meaning that that number of shares voted “for” such proposal exceeds the number of shares voted “against” such proposal.) Abstentions and broker non-votes are not considered votes cast for the foregoing purpose and will have no effect on the vote for these proposals.

Although our Board of Directors intends to carefully consider the shareholder vote on the compensation of our named executive officers, that vote will not be binding on us and is advisory in nature.

The inspector of election for the annual meeting shall determine the number of shares of common stock and Preferred Stock represented at the meeting, confirm the existence of a quorum and the validity and effect of proxies, and shall also count and tabulate ballots and votes and determine the results thereof. Proxies received but marked as abstentions and broker non-votes will be included in the calculation of the number of shares considered to be present at the meeting for purposes of determining a quorum. A “broker non-vote” will occur when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary power with respect to that proposal and has not received instructions from the beneficial owner. If less than a majority of the combined voting power of the outstanding shares of common stock and Preferred Stock is represented at the annual meeting, the holders of shares representing a majority of the voting power so represented may adjourn the annual meeting from time to time without further notice.

What are the Board’s recommendations?

As more fully discussed under Summary of Business Matters to be Voted On, our Board of Directors recommends a vote FOR the election of the respective nominees for director named in this proxy statement; FOR the ratification of the selection of Ernst & Young LLP; and FOR approval of the executive compensation.

Unless contrary instructions are indicated on the enclosed proxy, all shares represented by valid proxies received pursuant to this solicitation (and which have not been revoked in accordance with the procedures set forth below) will be voted (1) FOR the election of the respective nominees for director named in this proxy statement; (2) FOR the ratification of the selection of Ernst & Young LLP; (3) FOR approval of the compensation of our named executive officers; and (4) in accordance with the recommendation of our Board of Directors, FOR or AGAINST all other matters as may properly come before the annual meeting. In the event a shareholder specifies a different choice by means of the enclosed proxy, such shares will be voted in accordance with the specification made.

How do I vote?

If you are a holder of record (that is, if your shares are registered in your own name with our transfer agent), you may vote by proxy over the Internet, by telephone, or by signing, dating, and returning the enclosed proxy card. Voting instructions for each method are provided on the proxy card contained in the proxy materials.

If you are a participant in the Beacon stock fund under the Beacon 401(k) Profit Sharing Plan or a Beacon employee holding shares on the Shareworks platform, you may furnish voting instructions over the Internet, by telephone, or by signing, dating and returning the enclosed proxy card. Voting instructions for each method are provided on the proxy card contained in the proxy materials.

If you are a street name holder (that is, if you hold your shares through a bank, broker or other holder of record), you must vote in accordance with the voting instruction form provided by your bank, broker or other holder of record. The availability of telephone or internet voting will depend upon your bank’s, broker’s, or other holder of record’s voting process.

If you come to the meeting, you can vote in person. If you are a street name holder and wish to vote at the meeting, you must first obtain a proxy from your bank, broker or other holder of record authorizing you to vote.

Can I change my vote after I return my proxy card?

Yes. The giving of a proxy does not eliminate the right to vote in person should any shareholder giving the proxy so desire. Shareholders have an unconditional right to revoke their proxy at any time prior to the exercise of that proxy, by voting in person at the annual meeting, by filing a written revocation with our Secretary at our headquarters or by submitting a later dated proxy by telephone, over the Internet, or by mail.

2

Who pays for costs relating to the proxy materials and annual meeting?

The costs of preparing, assembling and mailing this proxy statement, the Notice of Annual Meeting of Shareholders and the enclosed Annual Report and proxy card, along with the cost of posting the proxy materials on a website, are to be borne by us. In addition to the use of mail, our directors, officers and employees may solicit proxies personally and by telephone, e-mail and other electronic means. They will receive no compensation in addition to their regular salaries. We may request banks, brokers and other custodians, nominees and fiduciaries to forward copies of the proxy material to their principals and to request authority for the execution of proxies. We may reimburse these persons for their expenses in so doing.

SUMMARY OF BUSINESS MATTERS TO BE VOTED ON

Proposal 1.

ELECTION OF DIRECTORS

Our Amended and Restated Certificate of Incorporation and Bylaws provide that our Board of Directors shall consist of not less than three members to serve one-year terms of office. The authorized number of directors for this election is set at eleven members. Upon election at the annual meeting, our directors will serve terms expiring at the 2022 Annual Meeting of Shareholders or until their successors have been duly elected and qualified. The following individuals are our nominees:

Philip W. Knisely

Julian G. Francis

Carl T. Berquist

Barbara G. Fast

Richard W. Frost

Alan Gershenhorn

Robert M. McLaughlin

Neil S. Novich

Stuart A. Randle

Nathan K. Sleeper

Douglas L. Young

Each nominee has consented to serve as a director; however, in the event that a nominee for a directorship is unable to accept election or if any other unforeseen contingencies should arise, it is intended that proxies will be voted for the remaining nominees, if any, and for such other person as may be designated by the Board of Directors, unless it is directed by a proxy to do otherwise.

Our Company has grown rapidly through organic growth and acquisitions to become the largest publicly traded distributor of residential and non-residential roofing materials and complementary building products in the United States and Canada, operating branches in all 50 U.S. states and six Canadian provinces. Accordingly, our nominees have experience in a variety of areas important to our Company, such as managing and overseeing the management of large public and private companies, corporate governance and executive compensation, strategic planning, mergers and acquisitions, financing growing businesses, international operations, cybersecurity, information technology and marketing, and experience in our industry. Our Nominating and Corporate Governance Committee and Board believe that these nominees provide us with the range and depth of experience and capabilities needed to effectively oversee the management of our Company. In addition, we believe our directors complement each other well and together comprise a cohesive unit in terms of Board process and collaboration.

Information about Our Nominees

The following information sets forth, as of December 22, 2020, certain information about our nominees (age is in parentheses after each name). Unless otherwise indicated, each person has been engaged in the principal occupation shown for the past five years. There are no family relationships between any of our directors or executive officers. The Board has determined that each of the following directors is independent under Nasdaq listing standards: Carl T. Berquist, Barbara G. Fast, Richard W. Frost, Alan Gershenhorn, Robert M. McLaughlin, Neil S. Novich, Stuart A. Randle, and Douglas L. Young. Independent members of our Board shall meet in executive session at least two times a year.

Proposal 2.

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee appointed Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2021.

The Board and the Audit Committee consider Ernst & Young LLP well qualified to serve as the Company’s independent registered public accounting firm and recommend ratification of such selection by the shareholders.

Although action by shareholders for this matter is not required, the Board and the Audit Committee believe that it is appropriate to seek shareholder ratification of the selection in order to provide our shareholders with a means of communicating their level of satisfaction with the performance of the independent registered public accounting firm and its level of independence from management. If the proposal is not approved and the selection of Ernst & Young LLP is not ratified by our shareholders, the Audit Committee will take this into consideration and will reconsider the appointment.

The Board of Directors recommends that you vote FOR the ratification of the retention of Ernst & Young LLP as our independent registered public accounting firm for our 2021 fiscal year.

11

Proposal 3.

ADVISORY VOTE ON EXECUTIVE COMPENSATION

The Company is presenting the following proposal, which gives you, as a shareholder, an advisory vote on the compensation of our named executive officers by voting for or against the following resolution:

“RESOLVED, that the shareholders approve the compensation of the Company’s named executive officers, as disclosed in the Compensation Discussion and Analysis, the compensation tables, and the related disclosure contained in the accompanying proxy statement.”

This resolution is required pursuant to Section 14A of the Securities Exchange Act. Although our Board of Directors intends to carefully consider the shareholder vote resulting from the proposal, the final vote will not be binding on us and is advisory in nature. The current frequency of the advisory vote on executive compensation is annually. The next vote on executive compensation is expected to occur at our 2022 Annual Meeting of Shareholders.

Our Company has grown rapidly through internal growth and acquisitions to become the largest publicly traded distributor of residential and non-residential roofing materials and complementary building products in the United States and Canada, operating branches in all 50 U.S. states and six Canadian provinces. We believe our past accomplishments, including consistent profitability and growth, support the effectiveness of our executive pay program, which is intended to attract, motivate and retain experienced and skilled executives. We also believe the program provides the named executive officers listed in our summary compensation table with compensation that is competitive within our industry, internally equitable and commensurate with their talents and responsibilities. The primary objective of the program is to closely align executive direct compensation with the attainment of our annual and long-term performance goals. The compensation of our executive officers consists of base salary, cash incentives, long-term incentive compensation in the form of Company stock options and stock unit awards, and certain perquisites such as an auto allowance, fuel reimbursement, and, on occasion, housing and other allowances for relocated executives. Cash incentives are linked to quantitative and qualitative performance objectives. Most of the target cash incentives for which our executives are eligible are linked directly to Company quantitative performance in accordance with the terms of the cash incentive program.

The Board of Directors recommends that you vote FOR the approval of the compensation of our named executive officers.

BOARD OF DIRECTORS’ MEETINGS,
COMMITTEES OF THE BOARD AND RELATED MATTERS

How often did the Board meet during fiscal year 2020?

During fiscal year 2020, our Board of Directors held nine meetings. No incumbent director attended fewer than 75 percent of the aggregate of (i) the number of meetings of the Board of Directors held during the period he or she served on the Board and (ii) the number of meetings of committees of the Board of Directors held during the period he or she served on these committees. All of our Board members attended the 2020 Annual Meeting of Shareholders. It is our policy for all directors to attend the Annual Meeting of Shareholders, unless attendance is not feasible owing to unavoidable circumstances, which this year may include the pandemic.

What is the Board’s leadership structure?

Philip Knisely serves as our non-executive Chairman of the Board. Our CEO, Julian Francis, also serves on the Board. The Board believes that this leadership model is appropriate for the following reasons:

• these roles enable decisive leadership, ensure clear accountability and foster alignment between the Board and management on corporate strategy;

• our Board has adopted strong and effective corporate governance policies and procedures to promote the effective and independent governance of the Company (See “Corporate Governance” and “Employee Code of Business Ethics and Conduct”);

• our independent directors meet in regularly scheduled executive sessions without management present; and

• in determining the appropriate leadership structure, the Board considered a number of factors, including the candor and dynamics of discussion among the directors and between directors and management and the effectiveness of Mr. Knisely’s service on the Board to date.

Because our Chairman of the Board has not been determined to be an independent director by our Board, our Board has elected a Lead Independent Director. Stuart Randle currently serves as the Board’s Lead Independent Director, and the responsibilities of this position include the following:

• preside at meetings of the Board’s independent directors;

• assign certain tasks to the Board’s committees from time to time;

• recommend agenda items and times for Board meetings; and

• perform such other functions as the Board may direct.

Our business and affairs are managed under the direction of our Board, which is the Company’s ultimate decision-making body, except with respect to those matters reserved to our shareholders. Our Board’s key mission is to maximize long-term shareholder value. Our Board establishes our overall corporate policies, selects and evaluates our executive management team (which is charged with the conduct of our business), and acts as an advisor and counselor to executive management. Our Board also oversees our business strategy and planning, as well as the performance of management in executing its business strategy and assessing and managing risks.

What is the Board’s role in risk oversight?

The Board takes an active role in monitoring and assessing the Company’s risks, which include risks associated with operations, credit, financing, cybersecurity, and capital investments. Management is responsible for the Company’s day-to-day risk management activities and our Board’s role is to engage in informed risk oversight. Our Board members also complete the Company’s risk assessment survey. Management, through its internal audit function, compiles an annual ranking of risks to which the Company could be subjected. Our Director of Internal Audit reviews the results of this risk assessment with the Audit Committee. Any significant risks are then reviewed by the Board and assigned for oversight. In fulfilling this oversight role, our Board focuses on understanding the nature of our enterprise risks, including our operations and strategic direction, as well as the adequacy of our risk management process and overall risk management system. There are a number of ways our Board performs this function, including the following:

• at its regularly scheduled meetings, the Board receives management updates on our business operations, financial results and strategy and discusses risks related to the business;

• the Audit Committee assists the Board in its oversight of risk management by discussing with management, particularly the Chief Executive Officer and Chief Financial Officer, our guidelines and policies regarding financial and enterprise risk management and risk appetite, including major risk exposures, and the steps management has taken to monitor and control such exposures; the Audit Committee also receives regular reports from the Company’s Chief Information Officer on cybersecurity risk management; and

13

• through management updates and committee reports, the Board monitors our risk management activities, including the annual risk assessment process, risks relating to our compensation programs, and financial and operational risks being managed by the Company.

The Compensation Committee also has oversight responsibility for risks and exposures related to employee compensation programs and management succession planning, and it assesses whether the organization’s compensation practices encourage risk taking that would have a material adverse effect on the Company. The Committee periodically reviews the structure and elements of our compensation programs and its policies and practices that manage or mitigate such risk, including the balance of short-term and long-term incentives, use of multiple performance measures, and a multi-year vesting schedule for long-term incentives. Based on these reviews, the Committee believes that our compensation programs do not encourage excessive risk taking.

Are Board members subject to a retirement age?

No person shall be nominated by the Board to serve as a director after he or she has passed his or her 72nd birthday, unless the Nominating and Governance Committee has voted, on an annual basis, to waive the mandatory retirement age for such director.

Do Board members receive orientation training and continuing development education?

All new directors are required to participate in an orientation program, which includes the introduction of the new directors to the Company’s principal officers and presentations by senior management to familiarize new directors with the Company’s strategic plans and business units. The Board has adopted a Director Education Program and will conduct at least one continuing professional development program for all Board members each year. In addition, continuing professional development opportunities for all directors will be conducted through the Company’s regular Board meetings and Board meeting materials; periodic Board or Board committee presentations by the Company’s officers concerning the Company’s strategies, business plans, management structure and significant financial, accounting and risk management issues; Board or Board committee presentations by outside parties; and other professional development opportunities, if appropriate and relevant to the duties of a director of the Company, including presentations and educational programs offered by various outside organizations, with appropriate expenses paid by the Company.

What standing committees has the Board established?

The Board of Directors has established three standing committees: (1) the Audit Committee, (2) the Compensation Committee and (3) the Nominating and Corporate Governance Committee.

Audit Committee

The Audit Committee held eight meetings in fiscal year 2020. The Audit Committee assists the Board in monitoring:

• management’s process for ensuring the integrity of our financial statements;

• the independent registered public accounting firm’s qualifications and independence;

• the performance of our internal audit function and independent registered public accounting firm; and

• management’s process for ensuring our compliance with legal and regulatory requirements.

As a key part of its responsibilities above, the Audit Committee selects the independent registered public accounting firm, approves the scope of the annual audit activities of the independent registered public accounting firm, approves the audit fee payable to the independent registered public accounting firm and reviews audit results with the independent registered public accounting firm. The Audit Committee currently is composed of Carl Berquist, Barbara Fast, Robert McLaughlin and Douglas Young, each of whom meets the independence criteria prescribed by applicable law and the rules of the SEC for Audit Committee membership and is independent under Nasdaq listing standards. The Board has also determined that Mr. Berquist and Mr. McLaughlin are “audit committee financial experts” as such term is defined in Regulation S-K promulgated by the SEC. Each of Messrs. Berquist, McLaughlin and Young and Major General Fast meet Nasdaq’s financial knowledge requirements. Mr. Berquist currently serves as the Chairman of the Audit Committee. Ernst & Young LLP currently serves as our independent registered public accounting firm and reports directly to the Audit Committee.

The Audit Committee operates under a formal charter that governs its duties and conduct. The Audit Committee charter complies with applicable Nasdaq and SEC rules and regulations. A copy of the charter is available on our web site at www.becn.com. In addition, the charter is available in print to any shareholder who requests it in writing to our Chief Financial Officer at Beacon Roofing Supply, Inc., 505 Huntmar Park Drive, Suite 300, Herndon, Virginia 20170.

Please refer to the Report of the Audit Committee, which is set forth in this proxy statement, for a further description of our Audit Committee’s responsibilities and its recommendation with respect to our audited consolidated financial statements for fiscal year 2020.

Compensation Committee

The Compensation Committee held six meetings in fiscal year 2020. The Compensation Committee of the Board of Directors reviews and makes recommendations to the Board regarding the compensation of the Chief Executive Officer. The Compensation Committee also reviews the Chief Executive Officer’s recommendations on and approves the compensation of executive officers and key employees of the Company. The Compensation Committee administers and makes awards under the Company’s stock plan. One of the key duties of the Compensation Committee is to provide a general review of our compensation and benefit plans to ensure that they meet our objectives. In addition, the Compensation Committee makes recommendations for adopting and changing major compensation policies and practices. The Compensation Committee also reviews and makes recommendations to the Board regarding the compensation of non-employee directors. The Compensation Committee reports its recommendations for cash and non-equity compensation to the full Board of Directors for approval and authorization. The Compensation Committee is composed of directors who are independent under Nasdaq listing standards (as adopted under SEC rules) and non-employee directors (as defined in Rule 16b-3 under the Securities Exchange Act) and who do not have “interlocking” or other relationships with us that would detract from their independence as committee members. At all times, at least two members of the committee shall be outside directors (as defined in Section 162(m) of the Internal Revenue Code). The current members of the Compensation Committee are Richard Frost, Alan Gershenhorn, Robert McLaughlin, Neil Novich, and Douglas Young, each of whom is independent under Nasdaq listing standards. Mr. Novich currently serves as the Chairman of the Compensation Committee.

The Compensation Committee operates under a formal charter that governs its duties and conduct. The Compensation Committee charter complies with applicable Nasdaq and SEC rules and regulations. A copy of the charter is available on our web site at www.becn.com. In addition, the charter is available in print to any shareholder who requests it in writing to our Chief Financial Officer at Beacon Roofing Supply, Inc., 505 Huntmar Park Drive, Suite 300, Herndon, Virginia 20170.

Please refer to the Compensation Discussion and Analysis and the Report of the Compensation Committee in this proxy statement for a further description of our Compensation Committee’s responsibilities, as well as its compensation philosophy, its engagement of Frederic W. Cook & Co., Inc. as its independent compensation consultant, and a description of considerations underlying each component of compensation paid to Beacon’s named executive officers for fiscal year 2020.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee held four meetings in fiscal year 2020. The Nominating and Corporate Governance Committee is responsible for identifying and recommending potential candidates qualified to become Board members, recommending directors for appointment to Board committees, establishing and maintaining compliance with corporate governance guidelines, and reporting to the Board of Directors on the Board’s self-evaluation questionnaire. The Nominating and Corporate Governance Committee is currently composed of Barbara Fast, Richard Frost, Alan Gershenhorn, and Stuart Randle, each of whom is independent under Nasdaq listing standards. Mr. Frost currently serves as the Chairman of the Nominating and Corporate Governance Committee.

When identifying, evaluating and considering potential candidates for membership on our Board, including those who might be recommended or nominated by our shareholders, the Nominating and Corporate Governance Committee considers, among other factors, relevant business and financial experience, integrity and willingness to devote the necessary time and energy. Our Board seeks independent directors with a broad diversity of experience, professions, skills, geographic representation and backgrounds that will enhance the quality of the Board’s deliberations and decisions. The Board is committed to actively seeking out highly qualified women and individuals from minority groups as well as candidates with diverse backgrounds, skills and experiences as part of the director selection process, and any search firm engaged by the Committee will be tasked with considering the characteristics described in the governance guidelines. The appointment of Major General Fast in 2018 and her re-nomination exemplify the Board’s commitment to highly qualified, diverse candidates. The Committee also leads the Board in an annual self-evaluation to determine whether the Board and its committees are functioning effectively and in compliance with the governance guidelines. This self-evaluation includes a review and assessment of the continuing independence of the Board’s non-management directors and whether Board membership and size reflects an appropriate level of diversity.

The Nominating and Corporate Governance Committee will consider nominees for our Board of Directors recommended by our shareholders, using the same criteria as for other candidates. Recommendations should be submitted in writing to Ross D. Cooper, our Corporate Secretary, at 505 Huntmar Park Drive, Suite 300, Herndon, VA 20170. The recommendation should include the name and address of the shareholder making the recommendation and evidence of his or her ownership of our common stock, including the number of shares and period of ownership, the name and address of the director candidate, and his or her resume or listing of qualifications, and the candidate’s signed consent to serve as a director if elected and to be named in the Proxy Statement. To be considered, the recommendation must be received by the Corporate Secretary not less than 90 calendar days and not more than 120 calendar days before the one-year anniversary date of our most recent Annual Meeting of Shareholders. The Nominating and Corporate Governance Committee may consider advice and recommendations from others, including search firms as it deems appropriate.

AUDIT COMMITTEE MATTERS

Audit Committee’s Pre-Approval and Procedures

The Audit Committee is responsible for the appointment, compensation, retention and oversight of the work of Ernst & Young LLP, our independent registered public accounting firm. The independent registered public accounting firm reports directly to the Audit Committee. As part of its responsibility, the Audit Committee established a policy requiring the pre-approval of all audit and permissible non-audit services performed by the registered public accounting firm. In pre-approving services, the Audit Committee considers whether such services are consistent with the SEC’s rules on auditor independence.

Prior to the engagement of the registered public accounting firm for an upcoming audit/non-audit service period, defined as a twelve-month timeframe, Ernst & Young LLP submits a detailed list of services expected to be rendered during that period as well as an estimate of the associated fees for each of the following four categories of services to the Audit Committee for approval.

• Audit Services consist of services rendered by an external auditor for the audit of our annual consolidated financial statements (including audit services performed to audit the Company’s accounting for income taxes) and internal controls and reviews of our quarterly financial statements. It also includes services that generally only an external auditor can reasonably provide, such as comfort letters, statutory audits, attest services, consents and assistance with and review of documents filed with the Securities and Exchange Commission.

• Audit-Related Services consist of assurance and related services by an external auditor that are reasonably related to audit or review of financial statements, including employee benefit plan audits, due diligence related to mergers and acquisitions, subscriptions for accounting research software, and accounting consultations.

• Tax Services consist of services not included in Audit Services above, rendered by an external auditor for tax compliance, tax consulting and tax planning.

• Other Non-Audit Services are any other permissible work that is not an Audit, Audit-Related or Tax Service.

Circumstances may arise during the twelve-month period when it may become necessary to engage the independent auditor for additional services not contemplated in the original pre-approval. In those instances, the Audit Committee requires specific pre-approval before engaging the independent auditor. The chairman of the Audit Committee, acting pursuant to delegated authority, may pre-approve any audit or non-audit services to be performed by the independent auditors, provided that any such approvals are presented to the Audit Committee at its next scheduled meeting.

Audit and Non-Audit Fees

The table below summarizes the fees and expenses billed by our independent registered public accounting firm, Ernst & Young LLP, for the fiscal years ended September 30, 2020 and 2019:

INFORMATION ON EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Overview

The responsibilities of our Compensation Committee are to review our compensation and benefit plans to ensure that they meet our objectives, recommend the annual compensation of the Chief Executive Officer, review the Chief Executive Officer’s recommendations on and approve compensation of our other named executive officers, and make recommendations for adopting and changing major compensation policies and practices. The Compensation Committee also administers and approves equity awards under our stock plan and administers and approves awards to our named executive offers under our cash incentive plan.

Objectives of Compensation Program

Our compensation practices are intended to attract, motivate and retain highly competent executives in a competitive marketplace. The program provides named executive officers listed in our summary compensation table with compensation that is industry competitive, internally equitable and commensurate with their skills, knowledge, experience and responsibilities.

The primary objective of our executive compensation program is to firmly align total executive compensation with the long-term interests of our shareholders and the attainment of our annual and long-term performance goals. The annual goals were historically based upon our adjusted earnings before taxes, and for fiscal 2020, adjusted earnings before interest, income taxes, depreciation and amortization and operating working capital as a percentage of net sales. The long-term goals were historically based on metrics such as our stock price, return on invested capital (“ROIC”), Adjusted Earnings Per Share (“Adjusted EPS”), acquisition synergies and average organic net sales growth, and for fiscal year 2020, Adjusted EPS and daily average organic net sales growth. Adjusted EPS is calculated by dividing Adjusted Net Income (which is net income excluding acquisition costs, restructuring costs, COVID-19 impacts (limited to costs directly related to our response to the COVID-19 pandemic), and the effects of tax reform) by the weighted-average diluted shares outstanding after assuming full conversion of the participating preferred stock and excluding the impact of any preferred stock dividends.

The compensation of our named executive officers consists of base salary, cash incentives, long-term incentive compensation in the form of Company stock options and restricted stock unit awards, and certain perquisites such as an auto allowance and fuel reimbursement. The Company also provides its named executive officers executive life insurance. From time to time, the Company will also pay for relocation expenses, including temporary housing, commuting airfare, automobile lease and related expenses, associated with relocating executives.

Use of Consultants and Peer Group Data

The Company establishes executive compensation levels through evaluation of a comprehensive benchmarking analysis prepared by Frederic W. Cook & Co., Inc. (“FW Cook”), an independent compensation consultant retained by the Compensation Committee. Although the Company does not use strict numeric benchmarking to establish individual executive compensation levels, the Company takes into account the 25^th percentile, median, and 75^th percentile level of compensation for similarly situated executives at the peer group companies used by the Compensation Committee to guide executive compensation decisions. Where direct comparisons are not available from the peer group, we utilize market-based executive pay survey data on similarly situated executives to help guide our decisions. Because job content, accountability, responsibility, incumbent seniority and performance criteria vary from one company to the next, our Compensation Committee uses the numerical benchmarking data and median levels of similarly situated executives’ information as a guideline in exercising its discretion in determining compensation for our named executive officers.

In reviewing and determining executive compensation levels for fiscal year 2020, FW Cook reviewed the latest data for a peer group of distribution companies, most of which are of similar sales, earnings, market capitalization, number of employees, and complexity as the Company, in developing its recommendations for executive compensation to the Compensation Committee. Based on the review performed by FW Cook, and at its recommendation, we continued to utilize the following peer group in assessing our executive compensation for fiscal year 2020: Anixter International, Applied Industrial Technologies, BMC Stock Holdings, Builders FirstSource, Fastenal Company, HD Supply Holdings, LKQ Corporation, MRC Global, MSC Industrial Direct, Patterson Companies, Pool Corporation, Univar, Veritiv Corporation, Watsco, W.W. Grainger, Inc. and WESCO International.

The Compensation Committee used the peer group data as general guidance, together with other information such as general business trends, the competitiveness of the markets in which we operate, individual performance, and its own judgment in setting overall executive compensation. In addition, the Committee considered the results of the then most recent shareholder advisory vote on our executive compensation held on February 11, 2020, at which almost 99% of the shares voting supported the compensation of our named executive officers. Although the approval was advisory in nature, the Committee viewed the overwhelmingly positive response as confirmation that our shareholders generally believe that the pay of the named executive officers is appropriately aligned with their performance and the performance of the Company as well as the interests of our shareholders.

20

The Compensation Committee considered various factors bearing upon FW Cook’s independence and determined that FW Cook is independent and that its engagement did not present any conflicts of interest. FW Cook provides no other services to the Company.

Base Salaries

The first element of our compensation program is salary. Each year, our Board of Directors evaluates the performance of our Chief Executive Officer, and the Compensation Committee considers the Board’s evaluation in determining an appropriate overall compensation package for our Chief Executive Officer. The Compensation Committee recommends the salary of our Chief Executive Officer to the full Board of Directors in light of that evaluation. Mr. Francis’s base salary was set at $800,000 for fiscal year 2020. The Compensation Committee considered the following quantitative and qualitative factors in evaluating the Chief Executive Officer’s performance in setting fiscal year 2020 compensation: the Company’s performance and relative total shareholder return, the value of Mr. Francis’s leadership, the compensation plans of chief executive officers of comparable companies, and the recommendations of an independent compensation consultant (discussed above).

Base salaries of our named executive officers other than the Chief Executive Officer are set annually by the Compensation Committee, taking into account the recommendations of the Chief Executive Officer. The base salary of each named executive officer is recommended by the Chief Executive Officer to the Compensation Committee after evaluating each named executive officer’s performance over the year in consideration of (i) the Company’s overall financial performance, (ii) the individual’s performance during the year and contributions to the Company, and (iii) other relevant factors (for example, market conditions). The amounts for named executive officers other than the CEO are set forth in the Summary Compensation Table under the heading “Salary.”

The Compensation Committee considers a number of factors when evaluating the Chief Executive Officer’s recommendations regarding base salaries for the other named executive officers. Periodically, the Compensation Committee reviews industry specific compensation surveys that provide detailed information regarding the compensation practices of industry peers, competitors and companies of similar market value. The Compensation Committee also considers the compensation recommendations provided by FW Cook. Other information that the Committee deems relevant, such as general business trends, the competitiveness of the markets in which we operate and special circumstances, also may be considered in its evaluation.

During the early stages of the COVID-19 pandemic and in response to the potential of prolonged business disruption, the named executive officers, excluding the CEO, had their annual base pay temporarily reduced by 25% over four bi-weekly pay periods, and in the case of the CEO, annual base pay was temporarily reduced by 25% over six bi-weekly pay periods.

Annual Cash Incentives

The second element of our compensation program is an annual cash incentive. Annual incentives are a significant component of executive compensation, reflecting the Company’s belief that management’s contribution to long-term shareholder returns (via increasing stock prices) comes from increasing current earnings and properly preparing the Company for future earnings growth. We believe these incentives play a key role in enabling us to attract, retain and motivate our employees.

For fiscal year 2020, under the terms of our management cash incentive plan, a target incentive amount was set for each participant. Those amounts are set forth below in the Grants of Plan-Based Awards table under the heading “Target.”

The incentives for our executive officers named in the Summary Compensation Table were based 60% on a Company-wide adjusted earnings before interest, taxes, depreciation and amortization (“AEBITDA”) target, 20% on a Company-wide operating working capital as a percentage of sales target (“Operating Working Capital”), and 20% on qualitative performance evaluations of strategic performance goals (“individual goals”). AEBITDA means net income (loss) excluding the impact of interest expense (net of interest income), income taxes, depreciation and amortization, stock-based compensation, acquisition costs, restructuring costs, COVID-19 impacts (limited to costs directly related to our response to the COVID-19 pandemic, which increased AEBITDA by $4.2 million in fiscal year 2020) and the effects of tax reform. AEBITDA is a non-GAAP financial measure that is equivalent to Adjusted EBITDA as reported in the Company’s periodic reports filed with the SEC and earnings releases. The numerator in the Operating Working Capital calculation is defined as inventory plus accounts receivable less accounts payable. The Operating Working Capital calculation is based on thirteen (13) month average Operating Working Capital divided by trailing twelve (12) month net sales, as reported in the Company’s consolidated financial statements. If the AEBITDA target was not met at the 100% level, the participant’s incentive with respect to that target was prorated on a straight-line basis if the participant achieved a range of 80% to 100% of target, with no incentive paid at or less than 80% of target. If the Operating Working Capital target was not met at 100% of target, the participant’s incentive with respect to that target was prorated on a straight-line basis if the participant achieved a range of 30 bps to 0 bps above target, with no incentive paid at or more than 30 bps higher than target. The individual goals are outlined below. In addition, each participant could receive an additional incentive above the target incentive amount if: (i) actual AEBITDA exceeds 100% of AEBITDA target (in an amount up to 100% of the AEBITDA portion of the target incentive if actual AEBITDA performance is 120% of the AEBITDA target); and/or (ii) actual Operating Working Capital exceeds 100% of Operating Working Capital target (in an amount up to 100% of the Operating Working Capital portion of the target incentive if actual Operating Working Capital performance is 50 bps below the Operating Working Capital target); and/or (iii) individual goals are exceeded (in an amount up to 20% of the individual goals portion of the target incentive if actual individual goals performance is 120% of target performance). Taken together,

21

each participant could earn an additional incentive up to 84% of their target incentive (if the participant achieves the maximum total payout of 200% for the AEBITDA target, weighted at 60%, the maximum total payout of 200% for the Operating Working Capital target, weighted at 20%, and the maximum total 120% payout for the individual goals, weighted at 20%, the overall total payout is 184% of the target incentive amount). The Chair of the Compensation Committee, in consultation with our Chairman, performs the individual goals evaluations of our Chief Executive Officer, and our Chief Executive Officer performs the individual goals evaluations of the remaining named executive officers. In each case, the results are then presented to and discussed with the Compensation Committee and FW Cook, and in the case of the Chief Executive Officer, presented to and discussed with the Board of Directors.

For fiscal year 2020, the Company achieved AEBITDA of approximately $471.6 million, compared to an established target of $514.5 million, and Operating Working Capital as a percent of trailing twelve (12) month sales of 18.81%, compared to an established target of 19.40% for the named executives. Our Board of Directors established the annual AEBITDA target and the Operating Working Capital target based on market conditions, reasonable rates of expected annual growth and reasonable working capital management. Based on the Company’s actual AEBITDA results that fell below target, each participant earned sixty percent (60%) of the AEBITDA portion of their target incentive. Based on the Company’s actual Operating Working Capital results that out-performed target, each participant earned two hundred percent (200%) of the Operating Working Capital portion of their target incentive. Although the Company did not meet all of its financial objectives, each participant achieved (or, in the case of Mr. Swank, exceeded) all long-term strategic objectives included in the participant’s individual goals. The qualitative portions of the performance incentive are described below. The incentive amounts paid to each named executive officer for fiscal year 2020 are set forth below in the Summary Compensation Table under the heading “Non-Equity Incentive Plan Compensation,” except for a small portion of Mr. Lonegro’s incentive which was guaranteed and is reported under the heading “Bonus.” Total incentives earned for fiscal year 2020, were $768,000 for Mr. Francis, $197,692 for Mr. Lonegro, $435,600 for Mr. Swank, $224,127 for Mr. Harrison, and $248,294 for Mr. Cooper.

In addition to the duties and responsibilities associated with their executive positions, each of our named executive officers are assigned specific individual goals in order to qualify for part or all of a 20% portion of their target incentive amount. If the goal objectives are exceeded, each named executive office can receive an additional incentive. For fiscal year 2020, these specific management objectives were largely equally weighted and are described below, along with the percentage of the target incentive amount earned by the complete achievement of the objective. In each case, each percentage can increase up to 20% (for example, 5% can be increased to 6%) if the performance criteria for the goal objective is exceeded.

Mr. Francis — in addition to his responsibility to lead and manage all aspects of the Company’s operational and financial performance, including vendor relations, environmental health & safety, human resources, sales and marketing, supply chain, information technology, credit, legal and investor relations, Mr. Francis’s specific fiscal year 2020 goals were:

Mr. Swank — in addition to being responsible for the management of the Company’s operations, supply chain, sales and marketing departments, including e-commerce and product pricing, Mr. Swank’s specific fiscal year 2020 goals were:

• ensure the Company’s gross margin rates were achieved (6.67%). Mr. Swank exceeded this goal through his leadership and development of strategies that coalesced the efforts of sales and operations, marketing, digital, logistics, procurement and pricing functions to drive improved price, cost and mix performance. The combination of these efforts led to the company outperforming expectations during the COVID-19 pandemic;

• achieve established organic growth rates (6.67%). Mr. Swank exceeded this goal through his leadership of key company initiatives, including enhancing performance of the lowest quintile branches, execution of the company’s On Time & Complete (Beacon OTC^®) service model, and the development and deployment of a remote selling effort that leveraged the company’s industry leading digital platform to enable a safe and touchless sales environment during the COVID-19 pandemic; and

Mr. Cooper successfully completed this goal through team development and effective distribution of the workload enabling a greater focus on the core business and improved profitability.

Each of the above-named executive officer’s respective specific management objectives reflect our focus on continued growth and improvement in execution over our past performance. Mr. Novich, in consultation with Mr. Knisely, reviewed the level of achievement of Mr. Francis’s specific management objective set forth above. Mr. Francis reviewed the level of achievement of Messrs. Lonegro, Swank, Harrison, and Cooper’s specific management objectives set forth above and reported his recommendations to the Compensation Committee. After careful consideration of the outcomes, the Compensation Committee recommended to the Board of Directors the payment of the incentive awards in the amounts set forth in the narrative above and in the Summary Compensation Table under the heading “Non-equity incentive plan compensation.”

In addition to the management cash incentive plan, the Compensation Committee retains full discretion to award discretionary bonuses to the Chief Executive Officer and others to reward extraordinary efforts by named executive officers in various projects or initiatives during the year. The Compensation Committee considers the Chairman’s and Chief Executive Officer’s recommendations in determining discretionary cash awards for our other named executive officers.

Equity Compensation

The third element of our compensation program is equity compensation. Equity compensation is intended to more closely align total compensation with the long-term financial interests of our shareholders. The equity compensation component of our compensation program is based upon awards of stock options and other stock awards.

Our Compensation Committee administers our stock plan. The purpose of the stock plan is to advance the interests of our shareholders by aligning compensation to the long-term performance results of the Company by:

• providing directors, officers, employees and other eligible persons with additional incentives;

• encouraging stock ownership by eligible persons;

• aligning the interests of eligible persons with the interests of the Company;

• encouraging eligible persons to remain with the Company or its affiliates; and

• attracting new employees, officers or directors to the Company or its affiliates.

In determining whether to grant stock options and other stock awards, and how many of such to grant to eligible persons under our stock plan, the quantitative analysis of peer group company stock awards provided by FW Cook is considered, and then consideration is given to each individual’s past performance and contribution to the Company, as well as that individual’s expected ability to contribute to the Company in the future. As part of the Company’s annual performance evaluation process each year, the CEO, after consultation with each other named executive, establishes that named executive’s performance objectives for the coming year. These performance objectives are not intended to be rigid or formulaic, but rather to serve as the framework upon which the CEO evaluates the executive’s overall performance. Individual performance objectives may include operational metrics and qualitative goals that may reflect corporate or departmental goals or may include specific operational and qualitative objectives with respect to the executive’s area of responsibility. These performance objectives also include the demonstration of leadership and decision making, effective communication, promotion of the Company’s strategic initiatives and values, commitment to excellence and work ethic and may include more specific objectives for the executive, such as the successful completion of major projects, successful integration of acquisitions, and organization capability building. The CEO’s evaluation of an executive’s performance relative to these objectives is inherently subjective, involving a high degree of judgment based on the CEO’s observations of, and interaction with, the executive throughout the year. The CEO also considers the executive’s prospects for future development and advancement within the Company in formulating an equity compensation recommendation. As an additional input to the CEO’s evaluation of an executive’s performance, the CEO assesses the overall performance of the Company in light of the dynamics of the markets in which the Company competes. As a result, no single performance objective or group of objectives is material to the CEO’s evaluation of the executive’s performance.

The above evaluation provides the basis for the CEO’s recommendation to the Compensation Committee of equity compensation for each named executive. The Compensation Committee meets with the CEO and discusses the CEO’s recommendations before meeting separately in executive session to discuss the CEO’s and FW Cook’s recommendations and making a final determination of the equity compensation to the named executives. The Compensation Committee applies similar factors in determining the equity compensation to the CEO. The Compensation Committee’s evaluation of the CEO’s overall performance relative to these factors also is inherently subjective, involving a high degree of judgment. As additional input to the Compensation Committee’s evaluation of the CEO’s performance, the Compensation Committee assesses the overall performance of the Company in light of the dynamics of the markets

24

in which the Company competes. As a result, no single performance objective or group of objectives is material to the Compensation Committee’s evaluation of the CEO’s performance.

Since the Company’s initial public offering and through fiscal year 2020, non-qualified stock options have been granted to key members of management at an exercise price equal to the closing price of the Company’s common stock as reported by Nasdaq on the date of grant. Accordingly, grants of stock options will produce value only if there are increases in the underlying stock price. In fiscal year 2011, we began issuing performance-based restricted stock unit awards to certain key members of management. Beginning in fiscal year 2014, we also began issuing time-based restricted stock unit awards to certain key members of management. Similar to stock options, we believe that restricted stock unit awards reward performance because the value of the stock is also linked to our Company’s long-term performance. The Compensation Committee believes that time-based and performance-based restricted stock unit awards can play an important retentive and motivational role that stock options alone may not.

The Company’s annual equity awards are typically made by the Compensation Committee in November of each year following the close of the Company’s fiscal year and subsequent to the approval of the annual budget for the upcoming fiscal year. The Company typically does not make stock option and other stock awards other than annually, except in certain cases for key members of management hired during the course of a year or to improve the retention of key management members.

On November 12, 2019, the Compensation Committee authorized awards of stock options, time-based restricted stock units and performance-based restricted stock units. All these awards were granted to our named executive officers and a number of other key employees using the recommendations from FW Cook and other considerations described above. For our named executive officers, the Compensation Committee set a target equity award value based upon recommendations from FW Cook, which reviewed peer group data, and taking into account the value of each named executive officer’s equity awards in prior years. Of that target value, and pursuant to the guidelines approved by our Board, approximately 50% of the target value was represented by performance-based restricted stock units, approximately 25% in time-based restricted stock units and approximately 25% in stock options. Under this methodology, the awards to each of our named executive officers were as follows:

• Mr. Francis was granted options to acquire 54,545 common shares (approximately 13.4% of the total stock option awards) and 53,780 restricted stock units (approximately 14.4% of the total restricted stock unit awards), composed of 17,927 time-based restricted stock units and 35,853 performance-based restricted stock units. These grants were based on the factors described above, Mr. Francis’ key role as Chief Executive Officer and his leadership to develop and execute the Company’s strategic plan and increase shareholder value.

• Mr. Swank was granted options to acquire 20,455 common shares (approximately 5.0% of the total stock option awards) and 20,167 restricted stock units (approximately 5.4% of the total restricted stock unit awards), composed of 6,722 time-based restricted stock units and 13,445 performance-based restricted stock units. These grants were based on the factors described above, Mr. Swank’s key role as Chief Operating Officer, his position in leading the company’s sales and marketing programs, and his influence on developing pricing and e-commerce strategies.

• Mr. Harrison was granted options to acquire 7,955 common shares (approximately 2.0% of the total stock option awards) and 7,843 restricted stock units (approximately 2.1% of the total restricted stock unit awards), composed of 2,614 time-based restricted stock units and 5,229 performance-based restricted stock units. These grants were based on the factors described above, Mr. Harrison’s key role as Chief Human Resources Officer, his position in assisting with our continued future growth, including the selection and development of the Company’s human resources, and his influence on leading the company’s physical safety programs.

• Mr. Cooper was granted options to acquire 7,045 common shares (approximately 1.7% of the total stock option awards) and 6,947 restricted stock units (approximately 1.9% of the total restricted stock unit awards), composed of 2,316 time-based restricted stock units and 4,631 performance-based restricted stock units. These grants were based on the factors described above, Mr. Cooper’s key role as General Counsel and his position in assisting with our continued future growth, including assisting with all acquisitions, as well as monitoring company-wide legal compliance.

• Mr. Nowicki was granted options to acquire 12,955 common shares (approximately 3.2% of the total stock option awards) and 12,773 restricted stock units (approximately 3.4% of the total restricted stock unit awards), composed of 4,258 time-based restricted stock units and 8,515 performance-based restricted stock units. These grants were based on the factors described above, Mr. Nowicki’s key role as Chief Financial Officer, his position to assist with our continued future operational growth and success, and his influence on formulating our future capital structure and maintaining positive investor relationships.

The stock option awards granted to our named executive officers had an exercise price of $33.47, vest one-third annually starting on the first anniversary of the grant and expire on the tenth anniversary of the date of grant. The time-based restricted stock unit awards granted to our named executive officers will vest and convert into common shares upon the third anniversary of the date of grant.

The performance-based restricted stock unit awards granted to our named executive officers will vest and convert after the end of fiscal year 2022, subject to the Company achieving fiscal year 2020, 2021 and 2022 Adjusted EPS and daily average organic net sales

growth targets established on the grant date for each component year, each weighted at 50%. Performance of each metric will be calculated at the end of the three-year period for each component year independently. The actual number of units that will vest can range from 0% to 200% of the award target, depending upon actual company performance and with respect to one-third of the award for each fiscal year, weighted for each metric, above or below the target levels. If the achievement of an Adjusted EPS target is at or less than 80% of target for a component year, no units associated with that target will vest. If the achievement is 100% of a target for a component year, 100% of the units associated with that target will vest. If the achievement is 120% or more of a target for a component year, 200% of the units associated with that target will vest. Achievement of a target between 80% and 100% and between 100% and 120% will be adjusted on the basis of straight-line interpolation. If the achievement of a daily average organic net sales growth rate target is two percentage points or more below target for a component year, no units associated with this target will vest. If the achievement of a daily average organic net sales growth rate target is 100% of target for a component year, 100% of the units associated with this target will vest. If the achievement of a daily average organic net sales growth rate target is two percentage points or more above target for a component year, 200% of the units associated with this target will vest. Achievement of a daily average organic net sales growth rate between two percentage points below target and target, and between target and two percentage points above target, will be adjusted on the basis of straight-line interpolation.

On November 17, 2019, the performance-based restricted stock awards that were granted in fiscal year 2017 vested. This award had two performance measures, two-year cumulative Adjusted EPS and average organic net sales growth, both equally weighted at 50%. The two-year cumulative Adjusted EPS target for this grant was $5.73. The Company achieved an actual two-year cumulative Adjusted EPS of $4.84. The two-year average organic net sales growth target for this grant was 4.0%. The Company achieved an actual two-year average organic net sales growth of 2.0%. As a result, the grant vested and settled at 13% of the original share target.

General Counsel Transition to Special Advisor

On December 28, 2020, the Company entered into an Executive Employment, Severance and Restrictive Covenant Agreement with Ross D. Cooper (the “Agreement”). The Agreement contemplates that Mr. Cooper will transition from his current role as Executive Vice President and General Counsel to a new position as Special Advisor. The transition will occur as of June 30, 2021, any earlier date on which Beacon appoints a new General Counsel, or otherwise as mutually agreed upon by the Company and Mr. Cooper (the “Transition Date”). The Agreement shall continue in effect from the Transition Date until December 31, 2023 (the “Term”). As the Company’s Special Advisor, Mr. Cooper’s duties shall consist of (i) sourcing, negotiating, and completing business development activities and (ii) any other projects assigned by Beacon’s Chief Executive Officer with Mr. Cooper’s consent. Mr. Cooper shall report to the Company’s Chief Executive Officer. It is expected that Mr. Cooper’s duties will require an average of approximately 25 hours per week. Mr. Cooper’s employment with Beacon shall be exclusive, other than with respect to teaching and related duties for American University or other educational institutions.

As of the Transition Date, Mr. Cooper’s existing Executive Severance and Restrictive Covenant Agreement (described below under “Executive Compensation—Potential Payments upon Termination or Change-in-Control—Severance Agreements”) shall terminate. If Mr. Cooper’s employment terminates prior to the Transition Date, the rights and obligations of the parties shall be determined solely under the terms of such earlier severance agreement.

Effective as of June 30, 2021 or, if later, the Transition Date, Mr. Cooper’s annual base salary shall be adjusted to $300,000. Mr. Cooper shall receive his full annual cash incentive for the performance period ending September 30, 2021, based on actual performance, unless Mr. Cooper’s employment is terminated for cause or he resigns without good reason. Mr. Cooper will not receive future annual cash incentive awards or equity-based compensation grants.

The Agreement contains non-competition provisions continuing through a restriction period. The restriction period is 12 months in the case of termination by the Company for cause or by Mr. Cooper without good reason. The restriction period is 24 months in the case of a termination by the Company without cause or by Mr. Cooper for good reason. In the case of a 12-month restriction period (termination for cause or voluntary resignation without good reason), the non-competition provisions shall apply broadly with respect to industry participants. In the case of a 24-month restriction period (termination without cause or for good reason), the non-competition provisions shall only apply with respect to a list of industry participants identified in, or pursuant to, the Agreement. During the applicable restriction period, Mr. Cooper will be subject to covenants with respect to non-solicitation, non-disparagement, and non-endorsement of competing products. Mr. Cooper is also subject to a perpetual confidentiality covenant.

In the event the Company terminates Mr. Cooper without cause or Mr. Cooper terminates for good reason, in addition to the annual cash incentive described above, the Company shall provide Mr. Cooper with the following benefits:

• annual base salary until the end of the Term, paid in equal periodic installments on the Company’s regular payroll dates; and

• continued vesting in all unvested equity awards which would have vested had Mr. Cooper remained employed through such vesting date.

26

“Cause” and “good reason” have definitions identical to those included in the Severance Agreements described below under “Executive Compensation—Potential Payments upon Termination or Change-in-Control—Severance Agreements.”

Mr. Cooper’s receipt of the above payments and benefits is conditioned upon the execution and delivery, not subsequently revoked, of a waiver and release of claims.

CFO Transition

The Company announced on November 25, 2019, that its Executive Vice President and Chief Financial Officer Joseph Nowicki would leave the Company during the fiscal year ending September 30, 2020. In connection with his departure, the Company and Mr. Nowicki executed a Separation Agreement dated November 24, 2019 (the “Agreement”). Pursuant to the Agreement, Mr. Nowicki remained Executive Vice President and Chief Financial Officer until his successor’s start date in the Chief Financial Officer role on May 15, 2020, after which he remained a full-time employee until his separation date on June 30, 2020. The other material terms of the Agreement are as follows: a) payment of current base salary and participation in benefit plans through the separation date; b) payment of continued salary for one year from the separation date at an annual rate of $505,918; c) payment of $493,271, representing 18 months of annual cash incentive based on Mr. Nowicki’s target 2020 fiscal year annual cash incentive; and d) reimbursement of COBRA premium for one year. At the separation date, the following long-term incentive awards became vested: a) any unvested options that would have vested in calendar year 2020; b) all outstanding unvested time-based RSUs; and c) unvested performance-based RSUs granted in February 2018. Vested stock options could be exercised for 90 days following the separation date. Benefits under the Agreement were subject to Mr. Nowicki’s execution of a general release and compliance with his existing restrictive covenant agreement (with Mr. Nowicki’s separation date being considered the date of resignation under the restrictive covenant agreement).

On May 15, 2020, Frank A. Lonegro became the Company’s Executive Vice President and Chief Financial Officer. Mr. Lonegro’s compensation consists of an annual salary of $550,000, with a target annual incentive of 80% of his annual salary. His incentive for fiscal year 2020 was prorated from his start date. The financial performance portion of his fiscal year 2020 incentive paid out at a minimum of target achievement.

For fiscal year 2020, on his start date, Mr. Lonegro was granted stock options and time-based restricted stock units under the Company's Second Amended and Restated 2014 Stock Plan (the “2014 Stock Plan”) having an aggregate value, after pro-ration, of $500,000 at the date of grant, with 25% of the value in options and 75% in time-based restricted stock units. The stock options will vest one-third annually starting on the first anniversary of the grant and expire on the tenth anniversary of the date of grant. The restricted stock units will vest on the third anniversary of the date of grant. In addition, on his start date, Mr. Lonegro was granted a sign-on award of stock options and time-based restricted stock units under the 2014 Stock Plan having an aggregate value of $700,000 at the date of grant, with 25% of the value in stock options and 75% in time-based restricted stock units. The stock options will vest one-third annually starting on the first anniversary of the grant and expire on the tenth anniversary of the date of grant. The restricted stock units will vest one-half annually starting on the first anniversary of the grant. Mr. Lonegro also receives relocation assistance and other benefits typical for Company executives.

Employment Agreements

Except for Mr. Cooper’s Executive Employment, Severance and Restrictive Covenant Agreement described above, and the Executive Severance and Restrictive Covenant Agreements described below under “Executive Compensation—Potential Payments upon Termination or Change-in-Control—Severance Agreements”, there are no other employment, severance or change-in-control agreements currently entered into by and between any current executive officer and the Company.

Stock Ownership Guidelines

Our named executive officers and members of our Executive Committee (consisting of divisional executive vice presidents and corporate executive vice presidents) are expected to own stock of the Company having a value set forth below:

• Chief Executive Officer = 5 times annual base salary

• Named executive officers and Executive Committee members = 2 times annual base salary

Until the ownership level is met, executives are required to retain 50% of net profit shares attributable to stock option exercises or vesting of restricted stock units until the specified ownership level is attained. Profit shares represent the shares remaining after payment of applicable tax obligations and, in the case of stock options, payment of the stock option exercise price. There is no defined time period to meet the stock ownership requirement. Participants may satisfy their ownership guidelines with (i) shares directly owned, (ii) shares held in the Company 401(k) plan, (iii) time vested restricted stock units (which settle in stock), even if not vested and (iv) “in-the-money” value of vested stock options, based upon the spread between the exercise price and the current stock price. Unvested stock options and unearned performance based restricted stock units are not counted.

27

In addition, pursuant to the Company’s Insider Trading and Prohibition of Hedging and Pledging Policy (available on the “Investor Relations” page at www.becn.com), Company directors, officers, employees and members of their households may not enter into hedging or monetization transactions or similar arrangements with respect to Company securities, including the purchase or sale of puts or calls or the use of any other derivative instruments, nor may they hold Company securities in a margin account or pledge Company stock as collateral for a loan.

Retirement and Executive Life Insurance Plans

The Company sponsors a defined contribution 401(k) plan, which covers substantially all of our U.S. employees, including our named executive officers. We currently provide a match of 50% of participants’ before-tax contributions up to 3% of eligible compensation. During fiscal year 2020, we contributed a match for each of the named executives. Additional annual profit-sharing contributions may be made at the discretion of the Board of Directors but were not made for fiscal year 2020.

Our named executive officers do not participate in any special or separate executive retirement plans. We consider our 401(k) plan to be an important factor in our ability to hire, retain and motivate our employees by providing an added measure of financial security for our employees.

The Company provides an executive life insurance benefits program for the named executive officers and other key executives. The program provides life insurance at a coverage level of three times (3x) base salary up to $2.0 million. The Company subsidizes the required premium payments for each employee.

Perquisites

We have no formal perquisites program. Personal benefits may be provided from time to time when we determine that such personal benefits are a useful part of an executive’s compensation package. Specifically, we have agreed to provide each of the named executive officers with a monthly auto allowance of $1,000 and reimbursement of their fuel costs and other driving expenses.

Tax Deductibility of Compensation

Section 162(m) of the Internal Revenue Code as in effect for fiscal years prior to 2018 limited the deductibility of executive compensation paid to the Chief Executive Officer and to each of the three other most highly compensated officers of a public company (other than the Chief Financial Officer) who are named executive officers to $1 million per year. However, compensation that was considered qualified “performance-based compensation” generally did not count toward the $1 million deduction limit.

The Tax Cuts and Jobs Act of 2017 amended Section 162(m) to cover a public company’s chief financial officer and eliminated the performance-based exception. Accordingly, the Company’s grants of stock options, performance-based restricted stock units and annual cash incentive payments made for fiscal year 2018 and later years no longer qualify for this exception. Under a transition rule, outstanding stock options and performance-based restricted stock units will not be subject to Section 162(m) as amended to the extent such compensation is considered paid pursuant to a binding written contract in effect as of November 2, 2017.

The Compensation Committee takes into consideration the potential deductibility of the compensation as one of the factors to be considered when establishing our executive compensation program. However, the Compensation Committee believes that its primary responsibility is to provide a compensation program that attracts, retains, and rewards our executive officers that are critical to our success. Following the Tax Cuts and Jobs Act, the Compensation Committee may continue to consider tax deductibility as a factor in determining executive compensation but may not structure its compensation arrangements around tax deductibility. The Compensation Committee will continue to monitor the effect of tax reform on our executive compensation program.

Incentive Compensation Recoupment Policy

In the event of a financial statement restatement resulting from misconduct by a named executive officer or an officer who is a member of our Executive Committee, the Compensation Committee will review all incentive compensation paid, awarded or granted on or after January 1, 2017 to the involved officer. In its sole discretion, the Compensation Committee can decide to recoup from the officer all or a portion of the following incentive compensation:

• Incentive Plan:  The Compensation Committee can (i) cancel and forfeit the officer’s annual incentive opportunity for the then current plan year, and/or (ii) require repayment of any incentive awards previously paid for prior years within the recoupment period described below.

• Equity:  The Committee can (i) cancel and forfeit any outstanding equity awards, (ii) require the officer to return a number of shares of Company stock received upon vesting and settlement of any restricted stock unit awards during the recoupment period described below (or pay the cash value of such shares), and (iii) require the officer to return a number of shares received upon the exercise of any stock options during the recoupment period described below (or pay the cash value of such shares).

28

The Compensation Committee may seek recoupment if the officer’s misconduct occurs within 36 months following the payment, vesting or award of the incentive compensation.

All named executive officers and members of the Executive Committee have agreed to the terms of this policy.

Report of the Compensation Committee

The Compensation Committee has reviewed and discussed the “Compensation Disclosure and Analysis” section of this proxy statement with management, including our Chief Executive Officer, Chief Financial Officer and General Counsel. Based on this review and discussion, the Compensation Committee recommended to the Board of Directors that the “Compensation Discussion and Analysis” section be included in this proxy statement.

¹ For Mr. Francis, this amount reflects a sign-on cash award and an amount equal to the prorated unpaid annual cash incentive from his previous employer. For Mr. Lonegro, this amount reflects the portion of the financial component of his annual incentive paid in excess of amounts earned under the performance measure.

² These amounts represent the estimated grant date fair value of time-based and performance-based restricted stock unit awards computed in accordance with FASB ASC Topic 718. They are recognized by the Company as share-based compensation expense over a three-year period. Assuming performance-based restricted stock units vest at the maximum level, which is 200% of the target, the grant date values of fiscal year 2020 performance-based restricted stock units would be as follows: Mr. Francis — $2,400,000; Mr. Swank — $900,008; Mr. Harrison — $350,029; Mr. Cooper — $309,999; and Mr. Nowicki — $569,994. For additional information regarding assumptions underlying the valuation of stock awards, please refer to Notes 2 and 6 of our audited financial statements included in our Annual Report on Form 10-K for fiscal year 2020.

³ These amounts represent the grant date fair value of the stock options computed in accordance with FASB ASC Topic 718. They are recognized by the Company as share-based compensation expense over the three-year vesting period. For additional information, please refer to Notes 2 and 6 of our audited financial statements included in our Annual Report on Form 10-K for fiscal year 2020.

⁴ These amounts represent the annual cash incentives that were paid during the first quarter of the following fiscal year.

⁵ For fiscal year 2020, these amounts include Company matching contributions to the 401(k) plan (combined totals of $8,550 for Mr. Francis, $2,594 for Mr. Lonegro, $10,650 for Mr. Swank, $10,650 for Mr. Harrison, $8,530 for Mr. Cooper and $4,265 for Mr. Nowicki) along with executive life insurance payments (including a tax gross-up of $42 for Mr. Francis, $71 for Mr. Swank, $70 for Mr. Harrison, $85 for Mr. Cooper and $130 for Mr. Nowicki), auto allowance, and fuel and other driving cost reimbursement. Mr. Francis' amount also includes a housing allowance of $52,598 (including a tax gross-up of $16,598) and a relocation reimbursement of $108,717 (including a tax gross-up of $49,031). Mr. Nowicki's amount also includes $112,859 of base pay continuation and $3,727 of COBRA medical benefits premium reimbursement as part of his separation agreement.

¹ These non-equity incentive plan awards were based on Company-wide AEBITDA, average operating working capital as a percentage of sales and individual performance. Mr. Lonegro’s award was based on a partial year of employment at the Company. See Compensation Discussion and Analysis under the headings “Annual Cash Incentives” and “CFO Transition.”

² These restricted stock units vest and convert into common shares after the end of fiscal year 2022, subject to the Company achieving fiscal year 2020, 2021 and 2022 Adjusted EPS and average organic net sales growth targets, each weighted at 50%, and the units can vest at a percentage equal to 0% to 200% of the target. See Compensation Discussion and Analysis under the heading “Equity Compensation.”

³ These time-based restricted stock units will vest and convert into common shares upon the third anniversary of the grant date, except for 29,983 of the restricted stock units granted to Mr. Lonegro, which will vest in two equal installments on the first and second anniversary of the date of the award. See Compensation Discussion and Analysis under the heading “CFO Transition.”

⁴ These stock options vest (become exercisable) in three annual installments on the first, second and third anniversaries of the grant date, and expire ten years from the date of grant. See Compensation Discussion and Analysis under the heading “Equity Compensation.”

⁵ These amounts represent the grant date fair value of stock options and restricted stock units awarded to the named executive officers in fiscal year 2020, computed in accordance with FASB ASC Topic 718. Assumptions used in calculating these amounts are included in Notes 2 and 6 of our audited financial statements included in our Annual Report on Form 10-K for fiscal year 2020.

^{____________________________}

¹ All stock options granted under our 2004 Stock Plan and our 2014 Stock Plan vest in three annual installments on the first, second and third anniversary of the grant date.

² These time-based restricted stock units vest and convert into common shares upon the third anniversary of the grant date, unless otherwise noted. The total market value is based on the price of our common stock of $31.07 per share at the end of fiscal year 2020.

³ These performance-based restricted stock units vest on the third anniversary of the grant date, subject to the Company meeting defined performance metrics. The total market value is based on the price of our common stock of $31.07 per share at the end of fiscal year 2020 and vesting at target.

⁴ These performance-based restricted stock units vest on November 16, 2020, subject to the Company meeting defined performance metrics. The performance conditions were satisfied during fiscal year 2020 and thereafter were subject only to time-based vesting. Accordingly, these restricted stock units are shown with other time-based restricted stock units.

The following table sets forth certain information regarding stock option awards exercised and restricted stock unit awards vested by the named executive officers during the fiscal year ended September 30, 2020:

OPTIONS EXERCISED AND STOCK VESTED

¹ Calculated by multiplying the difference between the market price and exercise price on the date(s) of exercise by the number of common shares acquired.

² Calculated by multiplying the market price on the vesting date(s) by the number of underlying common shares.

Potential Payments upon Termination or Change-in-Control

Equity Award Agreements

Pursuant to stock option award agreements with our named executive officers, all of their outstanding stock options will vest upon death, disability or retirement (i.e., termination on or after age 65) and in the event of a change in control (subject to the conditions discussed below).

Pursuant to restricted stock unit award agreements with our named executive officers, restricted stock units will vest upon death, disability, or, subject to the conditions discussed below, a change of control (at target in the case of performance-based units). In the case of retirement, restricted stock units will vest (in the case of performance-based units, at the end of the performance period based on actual performance, or upon death, if earlier, at the target level).

Equity awards granted in fiscal year 2015 and later contain a “double trigger” change in control mechanism. Unless an award is continued or assumed by a public company in an equitable manner, it shall become fully vested immediately prior to a change in control (at 100% in the case of a performance-based award). If an award is so continued or assumed, vesting will continue in accordance with the terms of the award, unless there is a qualifying termination (without cause or for good reason) within one-year following the change in control, in which event the award shall become fully vested immediately (at 100% in the case of a performance-based award). Options granted prior to fiscal year 2015 vest immediately upon a change in control.

For purposes of the equity award agreements, “change in control” means: (a) any individual or entity becomes the beneficial owner of securities of the Company representing 50.1% or more of the combined voting power of the Company; (b) the Company consummates a merger, consolidation or other similar transaction unless, following such transaction, more than 50% of the combined voting power of the surviving entity or its parent is then beneficially owned by all or substantially all of the beneficial owners of the Company’s outstanding securities immediately prior to such transaction, in substantially the same proportions; (c) the Company sells all or substantially all of its business and/or assets unless, following such sale, more than 50% of the combined voting power of the outstanding securities of the acquiring entity or its parent is then beneficially owned by all or substantially all of the beneficial owners of the Company’s outstanding securities immediately prior to such sale, in substantially the same proportions; or (d) during any period of two consecutive years or less, individuals who at the beginning of such period constituted the Board (and any new directors, whose appointment by the Board or nomination for election was approved by a vote of at least two-thirds of the directors who either were directors at the beginning of the period or whose appointment or nomination was so approved, other than those elected as a result of an

33

actual or threatened proxy contest) cease for any reason to constitute a majority of the Board. “Cause” and “good reason” have definitions substantially similar to those included in the Severance Agreements discussed below.

Severance Agreements

Pursuant to Executive Severance and Restrictive Covenant Agreements (the “Severance Agreements”) with each of our named executive officers (other than Mr. Nowicki), in the event the Company terminates a named executive officer without cause, or a named executive officer terminates for good reason, the Company shall provide the named executive officer with the following payments and benefits:

• 18 months of annual base salary (24 months in the case of the CEO), paid in equal periodic installments on the Company’s regular payroll dates;

• 150% (200% in the case of the CEO) of the named executive officer’s target annual cash incentive, paid in equal periodic installments over the salary continuation period;

• the annual cash incentive with respect to any fiscal year completed prior to the termination date but not yet paid, paid in a lump sum on the date such cash incentive is paid to other employees;

• to the extent named executive officer elects health benefit continuation under COBRA, continued participation in Beacon’s health plan at active employee rates for 12 months (18 months in the case of the CEO); and

• continued vesting in all unvested equity awards that are scheduled to vest in the 12-month period following the termination date.

For purposes of the Severance Agreement, “cause” means: (i) gross negligence or willful misconduct in the performance of duties, (ii) refusal to perform duties as reasonably and lawfully directed (subject to notice and cure period), (iii) any act of fraud or embezzlement, wrongful taking for personal use, or self-dealing, (iv) conviction for (or plea of guilty or nolo contendre to) any felony or lesser crime involving moral turpitude that reasonably would be expected to materially damage the Company financially or reputationally, (v) material failure to comply with any material written policy (subject to notice and cure period), (vi) use of any illegal drug or abuse or misuse of alcohol and/or prescription drugs which materially adversely affects performance, or (vii) dissemination of confidential information or breach of restrictive covenants (excluding any unintentional and de minimis violations that are promptly cured). “Good reason” means, without the named executive officer’s consent, (i) a material reduction in authority, duties, or responsibilities, (ii) a greater than ten percent (10%) reduction in base salary (on an annualized basis), other than as part of an across-the-board reduction affecting similarly situated Beacon executives of not greater than twenty percent (20%) on an annualized basis and not in excess of 12 months, (iii) a relocation of primary work location more than 50 miles (and not closer to the then primary residence), or (iv) a material breach by the Company of any employment agreement (subject to notice and cure period, and resignation after cure period).

A named executive officer’s receipt of the above payments and benefits is conditioned upon the execution and delivery, not subsequently revoked, of a waiver and release of claims.

The Severance Agreements contain non-competition provisions continuing through a restriction period. The restriction period is 12 months in the case of termination by the Company for cause or by the named executive officer without good reason. The restriction period is 24 months (36 months in the case of the CEO) in the case of a termination by the Company without cause or by the named executive officer for good reason. In the case of a 12-month restriction period (termination for cause or voluntary resignation without good reason), the non-competition provisions shall apply broadly with respect to industry participants. In the case of a 24-month or 36-month restriction period (termination without cause or for good reason), the non-competition provisions shall apply with respect to a list of industry participants identified in, or pursuant to, the Severance Agreement. During the applicable restriction period, the named executive officer will be subject to covenants with respect to non-solicitation, non-disparagement, and non-endorsement of competing products. The named executive officers are also subject to a perpetual confidentiality covenant.

Cooper Agreement

For a description of Mr. Cooper’s Executive Employment, Severance and Restrictive Covenant Agreement, please see “General Counsel Transition to Special Advisor” in the Compensation Discussion and Analysis.

Amounts Payable

The following table quantifies the amounts that would be payable to the named executive officers (1) upon termination of their employment without cause or for good reason under the terms of our Severance Agreements and (2) upon death, disability or retirement, or, if applicable, upon a change in control or qualifying termination following a change in control under the terms of our equity award agreements. The amounts shown assume that the triggering events occurred on the last day of our fiscal year, September 30. 2020. Mr. Nowicki is not included in the table as his separation date was prior to September 30, 2020, and amounts paid or payable under his Separation Agreement are set forth below the table. Amounts that would be payable to Mr. Cooper as

34

severance benefits under his Executive Employment, Severance and Restrictive Covenant Agreement cannot be quantified as of September30, 2020, since this agreement was entered into after the end of the last fiscal year and any potential severance benefits are not available until a Transition Date, which cannot currently be determined.

^{____________________________}

¹ Equity awards granted in fiscal years 2015 and later are subject to a “double trigger.” Amounts presented assume such awards were not continued or assumed by a public company in an equitable manner (with or without a termination), or were so continued or assumed followed by a qualifying termination (without cause or for good reason) within one year following the change in control.

² Based on a Company stock price of $31.07 as of September 30, 2020, and the difference between such stock price and the exercise price of unvested options. Pursuant to the terms of the Severance Agreements, stock option awards will continue to vest over 12 months following a termination without cause or for good reason. Accordingly, values for such a termination cannot be determined as of September 30, 2020, and the amounts shown assume a stock price of $31.07 on each future vesting date.

³ Based on a Company stock price of $31.07 as of September 30, 2020. Pursuant to the terms of the Severance Agreements, restricted stock awards will continue to vest over 12 months following a termination without cause or for good reason. Accordingly, values for such a termination cannot be determined as of September 30, 2020, and the amounts shown assume a stock price of $31.07 on each future vesting date. In addition, in the case of retirement, performance-based restricted stock units will vest at the end of the performance period based on actual performance, or upon death, if earlier, at the target level. Accordingly, values of performance-based restricted stock units at retirement cannot be determined as of September 30, 2020, and the amounts shown assume vesting at target and a stock price of $31.07 on the vesting date.

⁴ Amounts in this row consist of projected premiums for health benefit coverage, reduced by the amount of projected employee premiums, during the coverage continuation period for each named executive officer.

For a description of Mr. Nowicki’s Separation Agreement, please see “CFO Transition” in the Compensation Discussion and Analysis. Under the terms of his agreement, the values of his separation benefits as of June 30, 2020, the date of his separation, were as follows:vesting of restricted stock units — $582,619; salary continuation — $505,918; cash incentive amount — $493,271; reimbursement of COBRA premium — $14,908. The value of the vesting restricted stock units was calculated based on the price of the Company’s stock of $26.37 as of June 30, 2020, the date of vesting.In addition, the value of his vesting options of $21,178 was calculated based on actual value received (proceeds less exercise price) upon the subsequent exercise of such options.The total estimated value of his separation benefits was $1,617,894. Such benefits are conditioned on Mr. Nowicki’s continued compliance with his existing restrictive covenant agreement.

Pay Ratio

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Company is providing the following disclosure about the ratio of the annual total compensation of Mr. Francis, our Chief Executive Officer, to the median employee’s annual total compensation. SEC rules for identifying the median employee and calculating the pay ratio allow companies to apply various methodologies and assumptions and, as a result, the pay ratio reported by us may not be comparable to the pay ratio reported by other companies.

Identification of Median Employee

We selected September 30, 2020, the end of our fiscal year, as the date on which to determine our median employee. For purposes of identifying the median employee, we considered all 7,381 U.S. employees, excluding the CEO. We selected gross earnings (which we define as all earnings before pre-tax payroll deductions) as it represents a broad and comprehensive measure of all compensation delivered to our U.S. employees and is readily available. In addition, we measured compensation for purposes of determining the median employee using the twelve-month period ending September 30, 2020. Relying on the de minimis exemption under the rules, we excluded all non-U.S. employees (all located in Canada) who in the aggregate comprised less than 5% of our total employees. Our total number of U.S. employees was 7,381 and our total number of non-U.S. employees was 218.

Ratio

Mr. Francis’s annual total compensation, as reported in the 2020 Summary Compensation Table, was $4,105,918. The median employee’s fiscal year 2020 annual total compensation that would be reportable in the Summary Compensation Table was $60,383. Based on this information, the ratio of the annual total compensation of Mr. Francis to the annual total compensation of our median employee is 68 to 1.

Compensation Committee Interlocks and Insider Participation

During fiscal year 2020, Neil Novich, Barbara Fast, Alan Gershenhorn, Douglas Young, Robert McLaughlin and Richard Frost served on the Compensation Committee. There are no Compensation Committee interlocks. None of the members of the Compensation Committee is an officer, employee or former officer or employee of the Company or any of our subsidiaries.

Compensation of Directors

The following table summarizes the compensation earned by our directors during the year ended September 30, 2020:

Corporate Governance Committee chair annual retainer. In addition, the Committee instituted an annual Chairman’s retainer in connection with the transition from an executive to non-executive Chairman.

In July 2020, the Board of Directors established a Transaction Committee, currently consisting of Stuart Randle, Alan Gershenhorn, Rick Frost, Robert McLaughlin, Nathan Sleeper and Carl Berquist, for the purpose of exploring, evaluating and negotiating of a potential sale of Beacon’s interior products business. Mr. Randle serves as chair. The Transaction Committee will serve until the consummation of the recently announced sale of the business to affiliates of American Securities LLC. As compensation for service on the Committee, the chair will receive an annual retainer of $15,000 and each other member will receive an annual retainer of $7,500, in each case prorated for partial year service.

Additional fees may be payable if the number of Board or committee meetings exceed 12 or 8, respectively, during a fiscal year. We reimburse members of our Board of Directors for any out-of-pocket expenses they incur in connection with services provided as directors.

Directors who are employees of the Company do not receive compensation for their services as directors. The compensation set forth in the table above for Mr. Buck, consisting of salary, an annual cash incentive payment, time-based restricted stock units and certain other compensation, was paid for services as an employee. Employee compensation for Mr. Francis is set forth in the Summary Compensation Table above.

CORPORATE GOVERNANCE

We operate within a comprehensive plan of corporate governance for the purpose of defining responsibilities, setting high standards of professional and personal conduct and assuring compliance with such responsibilities and standards. We regularly monitor developments in the area of corporate governance. We are subject to the Sarbanes-Oxley Act and the Dodd-Frank Act which, among other things, establish, or provide the basis for, a number of corporate governance standards and disclosure requirements. We are following the requirements of the Sarbanes-Oxley Act, the Dodd-Frank Act and SEC rules as they relate to us.

EMPLOYEE CODE OF BUSINESS ETHICS AND CONDUCT

We have adopted the Beacon Roofing Supply, Inc. Code of Conduct, a code of ethics that applies to all of our directors, officers and employees, including our Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer and any other persons performing similar functions. This code of conduct is available on our website at www.becn.com. If we make any substantive amendments to this code of conduct or grant any waiver, including any implicit waiver, from a provision of the code to our Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer or any other persons performing similar functions, we will disclose the nature of such amendment or waiver on our website within four business days.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

We purchase products from Cornerstone Building Brands, Inc. (formerly Ply Gem Industries, Inc.) and its subsidiaries (collectively, “Cornerstone”), the largest North American integrated manufacturer and marketer of external building products for the commercial, residential, and repair & remodel construction industries. Investment funds managed by, or affiliated with, Clayton, Dubilier & Rice, LLC own a substantial minority of the capital stock of Cornerstone. During the twelve months ending September 30, 2020, Cornerstone invoiced us an aggregate of approximately $114 million. We believe that the terms of the purchases made from Cornerstone were no less favorable to the Company in the aggregate than would otherwise have been obtained from unrelated third parties. Our relationship with Cornerstone predates the CD&R investment in the Company.

On August 24, 2017, in connection with the execution of a stock purchase agreement with respect to the acquisition of Allied Building Products Corp. (the “Allied Acquisition”), the Company entered into an investment agreement (the “Investment Agreement”) with CD&R Boulder Holdings, L.P. (the “CD&R Stockholder” and, together with its affiliated funds, the “CD&R Investors”) and Clayton, Dubilier & Rice Fund IX, L.P. for the purchase of shares of Series A Cumulative Convertible Participating Preferred Stock, par value $0.01 per share (the “Preferred Stock”). On January 2, 2018, in conjunction with the closing of the Allied Acquisition, CD&R Stockholder purchased 400,000 shares of Preferred Stock with an aggregate liquidation preference of $400.0 million, at a purchase price of $1,000 per share. The Preferred Stock is convertible perpetual participating preferred stock of the Company, with an initial conversion price of $41.26 per share, subject to customary anti-dilution adjustments, and accrue dividends at a rate of 6.0% per annum (payable in cash or in-kind), subject to adjustment to 9.0% per annum on the occurrence of certain triggering events.

Subject to certain limitations, the Company has the option to redeem the outstanding Preferred Stock, in whole or in part, for an aggregate redemption price equal to two times the liquidation value of the shares being redeemed. In the event of a change of control of the Company, each holder of the Preferred Stock will have the option to require the Company to purchase all or any portion of its shares at a price per share equal to the liquidation value of such shares.

Holders of the Preferred Stock generally will be entitled to vote with holders of shares of the Company’s common stock on all matters submitted for a shareholder vote (voting together with holders of shares of the Company’s common stock as one class) and will be entitled to a number of votes equal to the number of votes to which shares of the Company’s common stock issuable upon conversion of such Preferred Stock would have been entitled. Additionally, certain matters will require the approval of the holders of a majority of the outstanding Preferred Stock, voting as a separate class. Holders of the Preferred Stock have agreed to cause the Preferred Stock and common stock beneficially owned to be voted at any meeting of shareholders (i) in favor of each director nominated and recommended by the Board for election and (ii) against any shareholder nominations for director or other shareholder proposals which are not approved and recommended by the Board.

The Investment Agreement provides that the CD&R Investors (i) may designate two directors, for so long as the CD&R Investors hold Preferred Stock (or shares of the Company’s common stock issued upon conversion of the Preferred Stock) representing at least 50% of the shares of Preferred Stock initially issued to the CD&R Stockholder at closing, and (ii) may designate one director, for so long as the CD&R Investors hold Preferred Stock (or shares of the Company’s common stock issued upon conversion of the Preferred Stock) representing less than 50%, but at least 25%, of such shares so received by the CD&R Stockholder.

For so long as the CD&R Investors hold Preferred Stock (or shares of the Company’s common stock issued upon conversion of the Preferred Stock) representing at least 25% of the shares of the Preferred Stock initially issued to the CD&R Stockholder at closing, the CD&R Investors will have customary preemptive rights to participate in future equity and equity-linked issuances by the Company up to the extent necessary to maintain its pro rata ownership percentage in the Company, subject to customary exceptions.

39

On January 2, 2018, pursuant to the Investment Agreement, the Company entered into a registration rights agreement with the CD&R Stockholder, pursuant to which the Company agreed to file a resale shelf registration statement for the benefit of the CD&R Stockholder and its permitted transferees (collectively, the “CD&R Stockholders”) upon the request of the CD&R Stockholder, and pursuant to which the CD&R Stockholders may make up to four requests that the Company conduct an underwritten offering of, or register, shares of the Company’s common stock received upon conversion of the Preferred Stock held by the CD&R Stockholders. The CD&R Stockholders also have customary piggyback registration rights and may request that the Company include their registrable securities in certain future registration statements or offerings of common stock by the Company. These registration rights will terminate when the CD&R Stockholders no longer own any registrable securities or Preferred Stock.

POLICIES AND PROCEDURES WITH RESPECT TO TRANSACTIONS WITH RELATED PERSONS

Our finance and legal departments are primarily responsible for identifying and reviewing relationships and transactions in which the Company and our directors, executive officers, and/or certain of our shareholders or their immediate family members are participants to determine whether any of these related parties had or will have a direct or indirect material interest. In order to identify potential related person transactions, our legal department annually prepares and distributes to all directors and named executives a written questionnaire which includes questions intended to elicit information about any related person transactions. Pursuant to the Company’s written contract review policy, approved by our Board, all agreements covered by this policy with “Related Persons,” as that term is defined pursuant to Item 404(a) of SEC Regulation S-K, must be submitted for review and approval by the Audit Committee. In evaluating related person transactions, our Audit Committee members apply the same standards of good faith and fiduciary duty they apply to their general responsibilities as a committee of the Board and as individual directors. The Audit Committee may approve a related person transaction when, in its good faith judgment, the transaction is in the best interests of the Company.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The firm of Ernst & Young LLP, independent registered public accounting firm, has been our auditor since 1997 and has advised us that the firm does not have any direct financial interest or indirect financial interest in the Company or any of its subsidiaries. It is expected that a representative of such firm will (i) attend the 2021 Annual Meeting of Shareholders, (ii) have an opportunity to make a statement if they desire to do so, and (iii) be available to respond to appropriate questions.

OTHER BUSINESS

The Board of Directors knows of no other business to be brought before the annual meeting. If, however, any other business should properly come before the 2021 Annual Meeting of Shareholders, the persons named in the accompanying proxy will vote proxies as in their discretion they may deem appropriate, unless they are directed by a proxy to do otherwise.

A copy of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020, including the financial statements and schedules but excluding certain exhibits, will be made available without charge to interested shareholders upon written request to us.
