A MESSAGE TO OUR STOCKHOLDERS

To our Fellow Stockholders,

You are cordially invited to attend the annual meeting of stockholders of Builders FirstSource, Inc., which will take place at the Sheraton Dallas Hotel, 400 Olive Street, Dallas, Texas 75201 on Tuesday, June 14, 2022, at 1:00 p.m., local time. Details of the business to be conducted at the annual meeting are given in the Notice of Annual Meeting of Stockholders, Proxy Statement, Notice Regarding the Availability of Proxy Materials, and form of proxy.

2021 was an exceptional year for our company. We delivered record financial performance by helping our customers become more productive, managing supply chain constraints and strengthening our geographic positions around the nation. Our integration of BMC Stock Holdings, Inc. (“BMC”) following the completion of the merger on January 1, 2021 outpaced our early targets and realized our planed cost synergy and productivity savings over two years ahead of our initial expectations. It has become increasingly clear that the BMC merger has brought us closer to our mission to be the leading supplier of building materials and services to homebuilders by promoting a people-first culture that delivers exceptional customer service and innovative solutions to help build more efficiently, thereby creating superior value for stakeholders. We want to thank our more than 28,000 team members for an incredible year and we are extremely proud of their outstanding results.

We are also excited about our recent investments in our digital strategy. In August 2021, we acquired WTS Paradigm, LLC (“Paradigm”), a software solutions and services provider for the building products industry. The acquisition is an important step forward in our strategy to invest in innovative digital solutions that will help our customers build more efficiently. Our management team is committed to streamlining the home buying experience and providing the digital tools to better align and integrate the homebuilding project lifecycle for our customers and supply partners.

Delivering long-term value to our stockholders remains a top priority for our Board of Directors and our management team. We completed over $1.2 billion worth of acquisitions in 2021. We also repurchased $2.0 billion of our common stock through the beginning of 2022, and our Board of Directors recently authorized the repurchase of an additional $1.0 billion of our common stock on February 17, 2022, demonstrating the financial strength of our company and our continued commitment to deploy our robust free cash flow.

Your vote is important to us. Even if you intend to join us in person, we encourage you to vote in advance so we will know we have a quorum of stockholders for the meeting. When you vote in advance, please indicate your intention to personally attend the annual meeting. Please see the Question and Answer section on page 3 of the Proxy Statement for instructions if you plan to personally attend the annual meeting.

On behalf of the Board of Directors and the executive management team, we would like to express our appreciation for your continued interest in the affairs of Builders FirstSource, Inc.

Sincerely,	Sincerely,
Paul S. Levy Chairman of the Board	David E. Flitman Chief Executive Officer and President

PROXY STATEMENT

Annual Meeting of Stockholders

June 14, 2022

This Proxy Statement is being furnished by Builders FirstSource, Inc. (the “Corporation,” the “Company,” or “Builders FirstSource”) in connection with a solicitation of proxies by its Board of Directors (the “Board of Directors” or the “Board”) to be voted at the annual meeting of the Corporation’s stockholders to be held on June 14, 2022 (the “annual meeting” or “meeting”). Whether or not you personally attend, it is important that your shares be represented and voted at the annual meeting. Most stockholders have a choice of voting over the internet, by using a toll-free telephone number, or, for stockholders who elect to receive their proxy materials by mail, by completing a proxy card and mailing it in the postage-paid envelope provided. Check the Notice Regarding the Availability of Proxy Materials, your proxy card, or the information forwarded by your bank, broker, or other stockholder of record, as applicable, to determine which voting options are available to you. The internet voting and telephone voting facilities for stockholders of record will be available until 12:00 p.m. Central Time on June 14, 2022. The Notice Regarding the Availability of Proxy Materials will first be mailed on or about May 5, 2022.

SOLICITATION AND RATIFICATION OF PROXIES

If a proxy card is signed and returned, it will be voted as specified on the proxy card, or, if no vote is specified, it will be voted “FOR” all nominees presented in Proposal 1, “FOR” Proposals 2 and 3, and “ABSTAIN” for Proposal 4. At any time before it is exercised, you may revoke your proxy by timely delivery of written notice to the Corporate Secretary, by timely delivery of a properly executed, later-dated proxy (including by internet or telephone vote), or by voting via ballot at the annual meeting. Voting in advance of the annual meeting will not limit your right to vote at the annual meeting if you decide to attend in person. If you are a beneficial owner, and your shares are registered in the name of a bank, broker, or other stockholder of record, to be able to vote in person at the annual meeting you must obtain, from the stockholder of record, a legal proxy and submit it together with your ballot at the meeting. See “Questions and Answers about the Meeting and Voting” in this Proxy Statement for an explanation of the term “beneficial owner.”

The proxy accompanying this Proxy Statement is being solicited by the Board of Directors. The Corporation will bear the entire cost of this solicitation, including the preparation and delivery of this Proxy Statement, the proxy, and any additional information furnished to stockholders. The Corporation has retained Innisfree M&A Incorporated (“Innisfree”) to perform various proxy solicitation services in connection with the solicitation of proxies for the annual meeting. The Corporation will pay Innisfree a fee not to exceed $25,000, plus out-of-pocket expenses, for such services. In addition to using the mail and the internet, proxies may be solicited by directors, executive officers, and other employees of Builders FirstSource or its subsidiaries, in person or by telephone. No additional compensation will be paid to directors, executive officers, or other employees for their services in this regard. Builders FirstSource will also request banks, brokers, and other stockholders of record to forward proxy materials, at the Corporation’s expense, to the beneficial owners of the Corporation’s shares.

If you have questions or need assistance voting your shares, please contact our proxy solicitor:

All shares for which proxies or voting instructions are returned are counted as present for purposes of determining the existence of a quorum at the annual meeting.

Internet Availability of Proxy Materials

As permitted by federal securities laws, Builders FirstSource is making this Proxy Statement and 2021 Annual Report on Form 10-K (the “2021 Annual Report”) available to its stockholders primarily via the internet instead of mailing printed copies of these materials to each stockholder.

If you received a Notice by mail, you will not receive a printed copy of the proxy materials by mail unless you request printed materials. If you wish to receive printed proxy materials, you should follow the instructions for requesting such materials contained on the Notice.

Questions and Answers about the Meeting and Voting

QUESTIONS AND ANSWERS ABOUT THE MEETING AND VOTING

What is a proxy?

A proxy is your legal designation of another person, called a proxy holder, to vote the shares that you own. We designated Timothy D. Johnson, our Executive Vice President, General Counsel, and Corporate Secretary, and Peter M. Jackson, our Executive Vice President and Chief Financial Officer, to act as proxy holders at the annual meeting as to all shares for which proxy cards are returned or voting instructions are provided by internet or telephone.

What is a proxy statement?

A proxy statement is a document that the Securities and Exchange Commission (the “SEC”) regulations require us to give you when we ask you to provide a proxy (by voting by phone or internet or, if applicable, by returning a proxy card by mail) designating the proxy holders described above to vote on your behalf.

What is the difference between a stockholder of record and a stockholder who holds stock in street name, also called a “beneficial owner?”

If your shares are registered in your name at our transfer agent, Computershare Investor Services, you are a stockholder of record.

If your shares are held through a broker, bank, trustee, nominee, or other similar stockholder of record on your behalf, your shares are held in street name and you are the beneficial owner of the shares.

How do you obtain admission to the annual meeting?

Stockholders of Record. Stockholders of record must bring a current government-issued photo identification card to gain admission to the annual meeting.

Street Name Holders. To obtain admission to the annual meeting, a street name holder must (i) bring a current government-issued photo identification card and (ii) ask his or her broker or bank for a legal proxy and must bring that legal proxy with him or her to the meeting. If you do not receive the legal proxy in time, bring your most recent brokerage statement with you to the meeting. We can use that to verify your ownership of Common Stock and admit you to the meeting. However, you will not be able to vote your shares at the meeting without a legal proxy. Please note that if you own shares in street name, and you are issued a legal proxy, any previously executed proxy will be revoked, and your vote will not be counted unless you appear at the meeting and vote in person.

Could COVID-19 or related developments affect the Corporation’s ability to hold an in-person meeting?

We are actively monitoring the COVID-19 situation. In the event that it is inadvisable or not possible to hold our annual meeting in person, we may decide instead to hold a virtual annual meeting that is accessible only through the internet. If we decide to use that format, we will announce the decision to do so in advance via press release, and details on how to participate will be available on the investor relations page of the Corporation’s website (https://investors.bldr.com).

What different methods can you use to vote?

By Written Proxy. Stockholders who elect to receive their proxy materials by mail may vote by mailing the written proxy card.

Builders FirstSource, Inc.  |  2022 Proxy Statement    3

Questions and Answers about the Meeting and Voting

By Telephone and Internet Proxy. All stockholders of record may also vote by telephone from the U.S., using the toll-free telephone number provided on the proxy card or in the website listed on the Notice, or by the internet, using the procedures and instructions described in the Notice or proxy card. Street name holders may vote by telephone or the internet if their bank, broker, or other stockholder of record makes those methods available. If that is the case, the bank, broker, or other stockholder of record will enclose the instructions with the Proxy Statement or other notice of the meeting. The telephone and internet voting procedures, including the use of control numbers, are designed to authenticate stockholders’ identities, allow stockholders to vote their shares, and confirm that their instructions have been properly recorded.

In Person. All stockholders may vote in person at the meeting (unless they are street name holders without a legal proxy, as described in the foregoing question).

If you have questions or need assistance voting your shares, please contact our proxy solicitor:

Stockholders may call toll free: (877) 825-8964

Banks and Brokers may call collect: (212) 750-5833

What is the record date and what does it mean?

The record date for the annual meeting is April 22, 2022. The record date is established by the Board of Directors as required by Delaware law. Stockholders of record at the close of business on the record date are entitled to receive notice of the annual meeting and to vote their shares at the meeting.

What are your voting choices for director nominees, and what vote is needed to elect directors?

For the vote on the election of the Class II director nominees to serve until the 2025 annual meeting, stockholders may:

• vote in favor of all nominees,

• vote against all nominees, or

• vote in favor of specified nominees and against other specified nominees, or abstain from voting on all or certain specified nominees.

At the annual meeting in 2022, directors will be elected by a majority of the votes cast in person or by proxy at the annual meeting. Each director nominee in 2022 has submitted an irrevocable resignation that will be effective upon the occurrence of (i) the failure of such director nominee to receive a majority of the votes cast and (ii) the acceptance of that resignation by the Board. Abstentions from voting have no effect on the outcome of such vote because the election of directors is determined on the basis of votes cast and abstentions are not counted as votes cast.

THE BOARD RECOMMENDS A VOTE “FOR” EACH OF THE DIRECTOR NOMINEES.

4    Builders FirstSource, Inc.  |  2022 Proxy Statement

Questions and Answers about the Meeting and Voting

What are your voting choices on the advisory vote to approve the 2021 compensation of the Corporation’s named executive officers, including the Corporation’s compensation practices and principles and their implementation?

In the non-binding vote to approve the 2021 compensation of the Corporation’s named executive officers, including the Corporation’s compensation practices and principles and their implementation, as discussed and disclosed in this Proxy Statement, stockholders may:

• vote in favor of the proposal,

• vote against the proposal, or

• abstain from voting on the proposal.

This proposal requires the affirmative vote of a majority of the votes represented and entitled to vote at the annual meeting. Accordingly, abstentions have the effect of a vote “against” Proposal 2. This is an advisory vote, and, as such, is not binding on the Board or the Compensation Committee. However, the Board and the Compensation Committee will consider the results of the vote when setting the compensation of the Corporation’s executive officers in the future.

THE BOARD RECOMMENDS A VOTE “FOR” PROPOSAL 2.

What are your voting choices on the ratification of the appointment of PricewaterhouseCoopers LLP as the Corporation’s independent registered public accounting firm, and what vote is needed to ratify their appointment?

On the vote on the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year 2022, stockholders may:

• vote in favor of the ratification,

• vote against the ratification, or

• abstain from voting on the ratification.

The proposal to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm will require the affirmative vote of a majority of the shares represented and entitled to vote at the annual meeting. Accordingly, abstentions will have the effect of a vote “against” Proposal 3. This vote is not binding on the Board or the Audit Committee.

THE BOARD RECOMMENDS A VOTE “FOR” PROPOSAL 3.

What are your voting choices on the stockholder proposal, if properly presented at the meeting, requesting that the Corporation adopt greenhouse gas emissions reduction targets?

On the vote on the stockholder proposal, if properly presented at the meeting, requesting that the Corporation adopt greenhouse gas emissions reduction targets, stockholders may:

• vote in favor of the stockholder proposal,

• vote against the stockholder proposal, or

• abstain from voting on the stockholder proposal.

The proposal to consider a stockholder proposal, if properly presented at the meeting, requesting that the Corporation adopt greenhouse gas emissions reduction targets, will require the affirmative vote of a majority of the shares represented and entitled to vote at the annual meeting. Accordingly, abstentions will have the effect of a vote “against” Proposal 4.

THE BOARD DOES NOT MAKE A RECOMMENDATION FOR PROPOSAL 4.

Builders FirstSource, Inc.  |  2022 Proxy Statement    5

Questions and Answers about the Meeting and Voting

What if a stockholder does not specify a choice for a matter when returning a proxy card?

Stockholders should specify their choice for each proposal described on the proxy card, if they receive one. However, proxy cards that are signed and returned, but for which no specific instruction is given, will be voted “FOR” all the director candidates listed in Proposal 1, “FOR” Proposals 2 and 3, and “ABSTAIN” for Proposal 4.

If any matters not specifically set forth in this Proxy Statement properly come to a vote at the meeting, either of the members of the Proxy Committee, comprised of Timothy D. Johnson and Peter M. Jackson, will vote regarding those matters in accordance with their best judgments.

What are broker non-votes and how are they counted?

Although your broker is the record holder of any shares that you hold in street name, it must vote those shares pursuant to your instructions. If you do not provide instructions, your broker may exercise discretionary voting power over your shares for “routine” items but not for “non-routine” items. All matters described in this Proxy Statement, except for the ratification of the appointment of our independent auditor, are considered to be non-routine matters. “Broker non-votes” occur with respect to a non-routine matter when shares held of record by a broker are not voted on such matter because the beneficial owner has not provided voting instructions and the broker either lacks or declines to exercise the authority to vote the shares in its discretion.

Broker non-votes will be counted as present for purposes of establishing a quorum. Broker non-votes will not have any effect on Proposal 1, since broker non-votes are not votes cast. Broker non-votes will have the effect of a vote “AGAINST” on Proposal 2 and Proposal 4, since broker non-votes are entitled to vote at the annual meeting but are not entitled to vote on “non-routine” items. Brokers have discretionary authority to vote on Proposal 3.

Can I change my mind and revoke or change my proxy?

Yes. A stockholder of record may revoke a proxy or change its vote prior to its exercise at the annual meeting by:

• submitting a later-dated vote by telephone or Internet no later than 12:00 p.m. Central Time on June 14, 2022;

• signing a valid, later-dated proxy card and submitting it so that it is received before the annual meeting in accordance with the instructions included in the proxy card;

• before the annual meeting, signing a written notice of revocation dated later than the date of the proxy and submitting it to our Corporate Secretary so that it is received before the annual meeting; or

• attending the annual meeting and voting in person.

Note that attendance at the annual meeting, by itself, will not revoke your proxy.

A street name holder may revoke a proxy given pursuant to this solicitation by following the instructions of the bank, broker, trustee, or other nominee who holds his or her shares.

Proposal 1 — Election of Directors

PROPOSAL 1 — ELECTION OF DIRECTORS

On January 1, 2021 (the “Merger Effective Date”), the Corporation completed its previously announced all stock merger transaction with BMC Stock Holdings, Inc., a Delaware corporation (“BMC”). The merger between the Corporation and BMC is referred to as the “Merger” throughout this Proxy Statement.

Pursuant to the Corporation’s By-laws, the Board is “classified,” which means it is divided into three classes of directors based on the expiration of their terms. Under the classified Board arrangement, directors are elected to terms that expire on the annual meeting date three years following the annual meeting at which they were elected and the terms are “staggered” so that the terms of approximately one-third of the directors expire each year.

There are currently 12 members of the Board of Directors. Three of the 12 directors, Daniel Agroskin, David Bullock, and Floyd Sherman, whose terms all expire in 2022, are retiring from the Board and not standing for election at the annual meeting. Only one of the three vacancies will be filled at the annual meeting, and, as a result, the size of the Board will be reduced from 12 to 10 directors and the number of Class II directors will be reduced from four to two. Accordingly, Proposal 1 seeks the election of two directors to fill the continuing directorships whose terms expire in 2022.

The term of the other Class II director, Mark A. Alexander, will expire at the annual meeting in 2022. The Board of Directors has nominated Mark A. Alexander and Dirkson R. Charles for election to a term that will expire at the annual meeting in 2025.

Nominee	Age	Position Held	Independent	AuditCommittee	CompensationCommittee	Nominating and CorporateGovernance Committee
Mark A. Alexander	63	Director	X	X
Dirkson R. Charles	58	Director	X

Unless otherwise indicated, all proxies that authorize the proxy holders to vote for the election of directors will be voted “FOR” the election of the nominees listed below. If a nominee becomes unavailable for election as a result of unforeseen circumstances, it is the intention of the proxy holders to vote for the election of such substitute nominee, if any, as the Board of Directors may propose. As of the date of this Proxy Statement, each of the nominees has consented to serve and the Board is not aware of any circumstances that would cause a nominee to be unable to serve as a director.

Builders FirstSource, Inc.  |  2022 Proxy Statement    7

Director Compensation

Director Compensation Program

Under the Amended and Restated Director Compensation Policy, directors are entitled to compensation for their service on the Board if they are not concurrently employed in any capacity by the Corporation or any of its subsidiaries. Under the Amended and Restated Director Compensation Policy in effect during 2021, Directors who met these standards (“Eligible Directors”) received an annual cash retainer of $100,000. In addition, the Chairman of the Board receives an annual cash retainer of $100,000 for service in such role, which is also payable quarterly.

In connection with the Merger, the Amended and Restated Director Compensation Policy was amended effective January 15, 2021 to increase the annual cash retainer from $85,000 to $100,000 and the fair market value of the annual grant of restricted stock units from $130,000 to $150,000. The annual fees for serving on the Board’s committees were not changed. Because quarterly cash retainers are paid in advance, in the quarter following such amendment legacy Builders FirstSource directors received a cash retainer true-up for the period of time during the prior quarter in which the increased cash retainer amount was in effect.

Directors receive annual fees for serving on the Board’s committees, but do not receive separate per meeting fees for attending Board or committee meetings. The annual fees for serving on the Board’s committees are as follows:

Committee	Chair Fee	Member Fee(non-Chair)
Audit Committee	$30,000	$5,000
Compensation Committee	$20,000	$5,000
Nominating and Corporate Governance Committee	$10,000	$5,000

Eligible Directors also receive annual grants of restricted stock units. In 2021, the number of shares underlying these awards is determined by dividing a dollar value ($150,000 per year) by the fair market value of our Common Stock on the date of grant. These awards vest in full on the earlier of the first anniversary of the grant date or upon such director’s cessation of service due to death, disability, or retirement. If a new Eligible Director joins the Board, or if an existing director’s status changes to allow him or her to qualify as an Eligible Director, that director will receive a grant of restricted stock units on a pro-rated basis for the remainder of the current director compensation year, which is the year from the date of the prior annual meeting of stockholders to the date of the next annual meeting of stockholders.

In lieu of receiving cash retainers, an Eligible Director may elect to receive fully vested shares of Common Stock having a value on the first day of the service quarter for which they are issued approximately equal to the amount of the cash retainer payment he or she would otherwise receive. Such stock grants in lieu of cash retainer payments will be awarded on a quarterly basis at the same time cash retainer payments would be made. The Board amended the Amended and Restated Director Compensation Policy on November 17, 2021 to clarify that directors may only elect to receive fully vested shares of Common Stock in lieu of cash retainers during an open trading window and such election will take effect the following year.

We do not compensate directors for any period of service in which they are not Eligible Directors.

Board Purpose and Structure

The mission of the Board is to provide strategic guidance to the Corporation’s management, to monitor the performance and ethical behavior of the Corporation’s management, and to maximize the long-term financial return to the Corporation’s stockholders, while considering and appropriately balancing the interests of other stakeholders and constituencies. The Board currently consists of 12 directors, but will be reduced to 10 directors upon election of the director nominees at the annual meeting as described above.

Director Independence

The Board of Directors is comprised of one management director, Mr. Flitman (who is the Corporation’s current President and CEO), Mr. Sherman (who is the Corporation’s former CEO and was an employee of the Corporation until March 31, 2019), and ten non-management directors. As part of its annual evaluation of director independence, the Board examined, among other things, whether any transactions or relationships exist currently, or existed during the past three years, between each independent director and the Corporation or its subsidiaries or independent registered public accounting firm (the “auditors”). If such transactions or relationships exist, the Board reviews the nature of those transactions or relationships, including under the relevant New York Stock Exchange Listing Standards (the “NYSE Standards”) and SEC standards, to determine whether those transactions or relationships would impair such director’s independence. The Board also examined whether there are, or have been within the past year, any transactions or relationships between each independent director and members of the senior management of Builders FirstSource or its affiliates. As a result of this evaluation, the Board affirmatively determined that each of Messrs. Levy, Agroskin, Alexander, Bullock, Christophe, Hayes, Milgrim, O’Leary, and Steinke, and director nominee Dirkson R. Charles, is independent under those criteria.

In addition, our Board of Directors affirmatively determined that all the members of the Compensation Committee and all the members of the Audit Committee except Ms. Boydston meet the additional independence requirements of the SEC and NYSE Standards to audit and compensation committee members. Pursuant to the NYSE Standards, Ms. Boydston may remain on the Audit Committee until July 19, 2022. As a result, the Compensation Committee and the Nominating and Corporate Governance Committee are each comprised solely of independent directors, and the Audit Committee is in compliance with the independence requirements of the SEC and the NYSE Standards.

16    Builders FirstSource, Inc.  |  2022 Proxy Statement

Information Regarding the Board and its Committees

Each year, the independent directors meet in regularly scheduled executive sessions outside the presence of management representatives. Interested parties, including stockholders, may communicate with the Chairman or the independent directors as a group through the process described in this Proxy Statement under the heading “Policy on Stockholder-Director Communications.”

Board Meetings and Attendance

In 2021, our Board of Directors met ten times, our Audit Committee met eight times, our Compensation Committee met three times, and our Nominating and Corporate Governance Committee met three times, including regularly scheduled and special meetings. During 2021, each of the Corporation’s incumbent directors attended at least 75% of the combined meetings of the Board and any committee on which such director served during his or her term as a director. Pursuant to the Builders FirstSource, Inc. Corporate Governance Guidelines (available on the Governance section of our website), all directors are strongly encouraged to attend the annual meeting. Any director who is unable to attend an annual meeting of stockholders is expected to notify the Chairman of the Board in advance of such meeting. In 2021, ten members of the Board were available at our annual meeting by conference call.

Board Leadership Structure and Role in Risk Oversight

The Board is led by the Chairman of the Board, Paul Levy. Neither David Flitman, the only employee director, nor Floyd Sherman, who was an employee of the Corporation until March 31, 2019, has any formal leadership role with the Board. Mr. Levy takes a leading role in establishing the timing, agenda, and procedure of Board meetings. However, each of the directors actively participates in guiding the actions of the Board. The Board has determined that this leadership structure is appropriate and effective due to the Board’s size, the working relationship that has developed between the directors as a result of their length of service on the Board, and the significant experience that the members of the Board have as directors and members of senior management with other companies. The Board reviews and guides the Corporation in the following areas, among others:

	Safety, including COVID-19		Regulatory and legislative developments
	Environmental, social and governance matters		Cybersecurity and data privacy
	Business strategy and policy, including industry and economic developments		Human capital management and diversity and inclusion
	Operations and system integrity		Annual budget, including capital investment plan
	Litigation and other legal matters		Integration

The Corporation’s Board of Directors recognizes that, although day-to-day risk management is primarily the responsibility of the Corporation’s management team, the Board plays a critical role in the oversight of risk management. In that light, the Board is active, as a whole and also at the committee level, in reviewing management’s assessment of the major risks facing the Corporation and management’s processes for monitoring and controlling these risks. The Board regularly receives information from senior management regarding the Corporation’s financial results, credit, liquidity, operations, and other matters, as well as reports from the Corporation’s Audit Committee and Compensation Committee. During its review of such information, the Board discusses and analyzes risks associated with each area, as well as risks associated with new business ventures and those relating to the Corporation’s executive compensation plans and arrangements. The Board assumes ultimate responsibility for ensuring that the Corporation’s management adequately assesses the risks facing the Corporation and appropriately manages those risks.

Builders FirstSource, Inc.  |  2022 Proxy Statement    17

Information Regarding the Board and its Committees

The Audit Committee is specifically responsible for overseeing and monitoring the quality and integrity of the Corporation’s financial reports and other financial information provided to its stockholders. This includes reviewing the results of management’s risk assessment and compliance with management policies as they relate to financial reporting. The Audit Committee also monitors the Corporation’s compliance with legal and regulatory requirements and the risks associated therewith. On a regular basis, the Audit Committee reviews with senior management significant areas of risk exposure, including financial reporting controls, operational risks, pending litigation, employee issues, cybersecurity, disaster recovery planning, and issues arising from complaints to the Corporation’s hotline and other risk detection mechanisms.

The Board and the Audit Committee take an active role in reviewing the Corporation’s cybersecurity risk and actions to reduce or mitigate it. The Corporation’s Chief Information Security Officer (the “CISO”) and Chief Information Officer (the “CIO”), and the Chief Financial Officer, continuously monitor internal and external cybersecurity threats and review and revise the Corporation’s cybersecurity defenses on an ongoing basis. The CISO and CIO prepare reports on cybersecurity metrics for the Audit Committee on a regular basis. The Chief Financial Officer and CIO present those reports to the Audit Committee and address any questions and concerns raised by the Audit Committee. At least annually, the Audit Committee meets with the CIO and CISO in person to discuss cybersecurity in greater detail. The Audit Committee reports to the Board regarding cybersecurity matters, and the Board addresses cybersecurity issues either directly with management or through the Audit Committee.

The Compensation Committee reviewed with management the design and operation of our compensation programs for all employees, including executive officers, for the purpose of determining whether such programs might encourage inappropriate risk-taking that could have a material adverse effect on the Corporation. After conducting its evaluation, the Compensation Committee concluded that the Corporation’s compensation programs do not encourage employees to take risks that are reasonably likely to have a material adverse effect on the Corporation.

Audit Committee

The Audit Committee is composed of four directors, of which Messrs. Hayes, Alexander, and Steinke are independent (as that term is defined by the NYSE Standards and SEC regulations). Mr. Hayes serves as the Chair of the Audit Committee. The Board of Directors affirmatively determined that all Audit Committee members are financially literate as defined by the NYSE Standards. All members of the Audit Committee were also designated by the Board as audit committee “financial experts” under the SEC’s guidelines. The Board further determined that Messrs. Hayes, Alexander, and Steinke meet the independence standards of both the SEC regulations and the NYSE Standards for audit committee members. Although Ms. Boydston does not meet the independence requirements of the NYSE Standards, she can remain on the Audit Committee until July 19, 2022, the one-year anniversary of the Company’s listing on the NYSE, at which time she will no longer serve on the Audit Committee. A copy of the Audit Committee charter is available on the Governance section of our website at www.bldr.com. The Audit Committee is a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Nominating and Corporate Governance Committee is charged with identifying potential nominees for director and considers a wide range of criteria, including skills, expertise, integrity, character, judgment, age, independence, corporate experience, length of service, diversity of background and experience, including with respect to race, gender and ethnicity, conflicts of interest and commitments, and other qualities which the Nominating and Corporate Governance Committee believes enhances the Board’s ability to manage and direct, in an effective manner, the affairs and business of the Corporation. The Nominating and Corporate Governance Committee may, from time to time, engage firms that specialize in identifying director candidates. In addition, the Nominating and Corporate Governance will also consider candidates recommended by stockholders.

Information Regarding the Board and its Committees

Stock Ownership Guidelines for Executives and Directors

Under the Corporation’s Stock Ownership Guidelines for Executives and Directors, each executive officer of the Corporation (who has not reached the normal retirement age of 67) and director of the Corporation is expected to acquire (within the later of five years after the adoption of the policy or appointment to office) and continue to hold shares of the Corporation’s Common Stock having an aggregate market value that equals or exceeds the requirement set forth below. Unvested restricted stock units will count toward the ownership requirement. Until the required level is met, a director or executive officer is required to retain fifty percent of the net shares of common stock received from the Corporation as compensation. Once the requirements are met, future sales are only permitted to the extent that such director or executive officer shall continue to meet the requirements immediately following such sale. Once the target beneficial ownership level is achieved, that director or executive officer will not be required to acquire any additional shares in the event the stock price decreases, provided the underlying number of shares remain held by such director or executive officer.

Position	Holding Requirement
CEO	5 times annual base salary
Executive Officers	3 times annual base salary
Directors	5 times annual cash retainer*

* Excluding cash retainers for serving as the chairperson of the Board or any of its committees or for serving on any of the committees.

The Nominating and Corporate Governance Committee administers compliance with this policy and has the discretion to enforce these guidelines on a case-by-case basis. An annual evaluation will be performed on April 1 of each year. As of April 1, 2022, all directors and executive officers were either in compliance with the policy or subject to the grace period for reaching the required totals.

Report of the Audit Committee

REPORT OF THE AUDIT COMMITTEE

The primary responsibility of the Audit Committee is to assist the Board of Directors of the Corporation (the “Board”) in fulfilling its oversight responsibilities relating to (i) the quality and integrity of the financial reporting process, (ii) compliance with legal and regulatory requirements, (iii) the performance of the Corporation’s internal audit function, and (iv) the appointment of the independent registered public accounting firm. Management is responsible for the financial statements and the financial reporting process, including the implementation and maintenance of effective internal controls. The independent registered public accounting firm, PricewaterhouseCoopers LLP (“PwC”), is responsible for expressing an opinion on the Corporation’s financial statements and its internal control over financial reporting. The Board has concluded that (i) Messrs. Hayes, Alexander, and Steinke satisfy the applicable independence requirements set forth in the New York Stock Exchange Listing Standards (the “NYSE Standards”), and (ii) each of the Audit Committee members satisfies the applicable independence requirements set forth under SEC Rule 10A-3, and meets the financial literacy requirements for audit committee membership under the NYSE Standards and the rules and regulations of the SEC. The Board has also designated the chair of the Audit Committee, W. Bradley Hayes, and committee members Mark A. Alexander, Cory J. Boydston, and Craig A. Steinke as Audit Committee “financial experts” under the SEC’s guidelines. The Audit Committee has reviewed and discussed with management and PwC the Corporation’s audited financial statements as of and for the year ended December 31, 2021.

During 2021, the Audit Committee conducted eight meetings. The Audit Committee chair and other members of the Audit Committee reviewed and commented on the Corporation’s earnings news release and interim financial statements contained in the Corporation’s quarterly report on SEC Form 10-Q during each quarter, and met and discussed the Corporation’s draft Annual Report on SEC Form 10-K with the chief financial officer, general counsel, and PwC prior to the report’s filing and public release. The Audit Committee considers various relevant factors including qualifications, performance, and independence when appointing the audit firm and evaluating the audit firm annually. The Audit Committee is also involved in the selection process of the lead engagement partner when rotation is required after five years under the SEC’s audit partner rotation rules or for other reasons. Due to rotational requirements, a new lead engagement partner was selected effective for the 2022 fiscal year. In addition, the Audit Committee reviewed and ratified its Charter which is available within the Governance section of the Corporation’s website.

The Audit Committee discussed with PwC the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. Both the vice president of internal audit and PwC have complete and direct access to the Audit Committee, and the Audit Committee has the same access to the vice president of internal audit and PwC. The Audit Committee met with the vice president of internal audit and PwC, with and without management present, to discuss the results of their examinations, their evaluations of the Corporation’s internal controls, and the overall quality of the Corporation’s financial reporting process. The Audit Committee met separately with the Corporation’s chief financial officer and general counsel. The Audit Committee discussed with management the status of pending litigation, taxation, and other areas of oversight relating to financial reporting and audit processes as the Committee determined to be appropriate. The Audit Committee also reviewed the Company’s Enterprise Risk Management (ERM) program, including, among other topics, specific information security risks. The Audit Committee recommended that many of these topics be addressed in presentations to the Board. The Audit Committee has discussed the overall scope of the Corporation’s internal audits and approved the annual internal audit plan. The Audit Committee reports the results of these discussions to the Board on a quarterly basis.

The Audit Committee received and reviewed the written communications from PwC as required by applicable requirements of the Public Company Accounting Oversight Board for independent auditor communications with audit committees concerning independence, and has discussed with PwC its independence. The Audit Committee has adopted procedures for pre-approving all audit, audit-related, and non-audit services provided by PwC, which included reviewing and approving estimated fees for audit, audit-related, and permitted non-audit services. The Audit Committee considers the compatibility of all services provided by PwC with its independence and has concluded the provision of the non-audit services is compatible with maintaining PwC’s independence. During the fiscal year ended December 31, 2021, PwC was employed principally to perform the annual audit and to render tax services. The Audit Committee reviewed the audit engagement letter and approved all fees paid to PwC for audit, audit-related, and non-audit services.

Corporate Governance

CORPORATE GOVERNANCE

Builders FirstSource is committed to conducting its business in a way that reflects best practices, as well as the highest standards of legal and ethical conduct. To that end, the Board of Directors has approved a comprehensive system of corporate governance documents and policies. These documents and policies are reviewed periodically and updated as necessary to reflect changes in regulatory requirements and evolving governing practices. These policies embody the principles, policies, processes, and practices followed by the Board, executive officers, and employees in governing the Corporation and serve as a flexible framework for sound corporate governance.

Code of Business Conduct and Ethics

Builders FirstSource and its subsidiaries endeavor to do business according to the highest ethical and legal standards, complying with both the letter and spirit of the law. Our Board of Directors approved a Code of Business Conduct and Ethics that applies to the Corporation’s directors, officers (including our principal executive officer, principal financial officer, principal accounting officer, and controller), and employees. Our Code of Business Conduct and Ethics is administered by the Compliance Committee, which is made up of representatives from our Finance, Legal, Human Resources, and Internal Audit Departments. Our employees are encouraged to report any suspected violations of laws, regulations, or the Code of Business Conduct and Ethics and all unethical business practices. We provide a continuously monitored hotline for anonymous reporting by employees. Our Board of Directors also approved a Supplemental Code of Ethics for Chief Executive Officer, President, and Senior Financial Officers of Builders FirstSource, Inc., which is administered by our General Counsel. Both policies can be found on the Governance section of our corporate website at www.bldr.com. Stockholders may request a free copy of these policies by contacting the Corporate Secretary, Builders FirstSource, Inc., 2001 Bryan Street, Suite 1600, Dallas, Texas 75201.

In addition, within four business days of:

• any amendment to our Code of Business Conduct and Ethics or our Supplemental Code of Ethics that applies to our Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer, or Controller, or

• the grant of any waiver, including an implicit waiver, from a provision of one of these policies to one of these officers

that relates to one or more of the items set forth in Item 406(b) of Regulation S-K, we will provide information regarding any such amendment or waiver (including the nature of any waiver, the name of the person to whom the waiver was granted, and the date of the waiver) on our website at the internet address above. Such information will be available on our website for at least a 12-month period. In addition, we will promptly disclose any waivers to our Code of Business Conduct and Ethics and our Supplemental Code of Ethics as required by the NYSE Standards.

Additionally, the Corporation has adopted a Related Party Transaction Policy that works in conjunction with the Code of Business Conduct and Ethics and sets forth the process by which the Audit Committee will review certain related party transactions between the Corporation and its executive officers, directors, and greater than five percent beneficial owners, and their immediate family members, and the Corporation.

By-law Provisions on Stockholder Nominations of Director Candidates

Builders FirstSource’s By-laws provide that, other than pursuant to the Corporation’s proxy access provision (which is described below), no director candidate may be nominated by a stockholder for election at a meeting unless the stockholder (i) has delivered to the Corporate Secretary, within the time limits described in the By-laws, a written notice containing the information specified in the By-laws and (ii) was a stockholder of record (a) at the time such notice was delivered to the Corporate Secretary and (b) on the record date for the determination of stockholders entitled to notice and to vote at the meeting at which such director is standing for election. Accordingly, in order for a stockholder’s nomination of a person for election to the Board of Directors to be

Corporate Governance

considered by the stockholders at the 2023 annual meeting in accordance with the Corporation’s By-laws, the required written notice must be received by our Corporate Secretary on or after February 14, 2023, but no later than March 16, 2023. Only individuals nominated in accordance with the procedures set forth in the By-laws are eligible to stand for election as directors at a meeting of stockholders and to serve as directors. A copy of the By-laws may be obtained on the Governance section of our website at www.bldr.com, by written request to the Corporate Secretary, Builders FirstSource, Inc., 2001 Bryan Street, Suite 1600, Dallas, Texas 75201, or by e-mail at inforequest@bldr.com. The foregoing is subject to the Corporation’s obligations under SEC Rule 14a-8 regarding the inclusion of stockholder proposals in the Corporation’s proxy statements, which is further described below in “Stockholder Proposals.”

Policy on Stockholder Recommendations for Director Candidates

The Nominating and Corporate Governance Committee adopted a Policy on Stockholder Recommendations for Director Candidates to describe the process by which the Nominating and Corporate Governance Committee (in preparing their recommendation of director nominees to the Board) will consider candidates for director recommended by stockholders in accordance with the Corporation’s By-laws. A current copy of the Policy on Stockholder Recommendations for Director Candidates is available on the Governance section of our website at www.bldr.com. To have a candidate considered by the Nominating and Corporate Governance Committee, a stockholder must submit the recommendation in writing and must include the information set forth in the Policy on Stockholder Recommendations for Director Candidates.

Proxy Access for Director Nominations

In addition to the above, Builders FirstSource’s By-laws also include a proxy access provision, which permits a stockholder, or a group of up to 20 stockholders, owning 3% or more of the Corporation’s outstanding Common Stock continuously for at least three years to nominate and include in the Corporation’s proxy materials director nominees constituting up to two individuals or 20% of the Board (whichever is greater); provided, however, that for so long as the Corporation has a classified Board of Directors, in no case shall the number of nominees appearing in the Corporation’s proxy materials exceed one-half of the number of directors to be elected at such annual meeting (rounded down to the nearest whole number).

Pursuant to the Corporation’s By-laws, to be timely for inclusion in the proxy materials for our 2023 annual meeting, a stockholder’s written notice to nominate a director using the Corporation’s proxy materials must be received by our Corporate Secretary on or after February 14, 2023, but no later than March 16, 2023. Such notice should be addressed to the Corporate Secretary, Builders FirstSource, Inc., 2001 Bryan Street, Suite 1600, Dallas, Texas 75201. The notice must contain the information required by our By-laws, and the stockholder(s) and nominee(s) must comply with the information and other requirements in our By-Laws relating to the inclusion of stockholder nominees in our proxy materials. A copy of the By-laws may be obtained on the Governance section of our website at www.bldr.com, by written request to the Corporate Secretary, Builders FirstSource, Inc., 2001 Bryan Street, Suite 1600, Dallas, Texas 75201, or by e-mail at inforequest@bldr.com.

Corporate Governance Guidelines

Builders FirstSource adopted its Corporate Governance Guidelines to assist the Board in the exercise of its duties and responsibilities. The Corporate Governance Guidelines set forth the practices the Board follows with respect to, among other matters, the composition of the Board, director responsibilities, Board committees, director access to officers and independent advisors, director compensation and the performance evaluation of the Board. A current copy of the Corporate Governance Guidelines is available on the Governance section of our website at www.bldr.com.

The Corporate Governance Guidelines limit the number of other public company boards our directors may join to ensure that a director is not “overboarded” and is able to devote the appropriate amount of time and attention to the oversight of the Corporation. Ordinarily, directors may not serve on the boards of more than four public companies, including our Board. Directors who are chief executive officers of public companies may not serve on

24    Builders FirstSource, Inc.  |  2022 Proxy Statement

Corporate Governance

the boards of more than two other public companies, in addition to our Board. No member of the Corporation’s Audit Committee may serve on more than three public company audit committees (including our Audit Committee). Service on the boards of subsidiary companies with no publicly traded stock (or that issue only debt), non-profit organizations and private companies is not included in this calculation. Any director seeking to join the board of directors of another company must first notify the Nominating and Corporate Governance Committee and obtain its approval to continue as a member of our Board.

A key responsibility of the Board is overseeing the identification and development of senior leadership. The Corporate Governance Guidelines outline a succession planning process that includes consideration of both ordinary course succession, in the event of planned promotions and retirements, and planning for situations where the Chief Executive Officer or another member of senior management unexpectedly become unable to perform the duties of their positions. To assist the Board, the Compensation Committee reviews our succession plans, monitors development of qualified candidates for principal positions in the Corporation, and reviews succession planning and management development at least annually with the Board.

Each year, the Board, as required by the Corporation’s Corporate Governance Guidelines, conducts an evaluation of its performance and effectiveness. As set forth in its charter, the Nominating and Corporate Governance Committee oversees this process. The Board and each committee conduct self-evaluations generally at the first regularly scheduled meetings of the fiscal year. These self-evaluations solicit feedback on a range of issues, including Board and committee structure, culture and dynamics, meeting content, and interactions with management.

Communication with Directors

Stockholders and other interested parties may contact any member (or all members) of the Board (including the non-management or independent directors as a group, any Board committee, or any chair of any such committee) in writing by mail or overnight service or electronically. To communicate with the Board of Directors, any individual directors, or any group or committee of directors, correspondence should be addressed to the Board of Directors or any such individual directors or group or committee of directors by either name or title. All such correspondence should be sent to the Corporation in care of the Corporate Secretary at 2001 Bryan Street, Suite 1600, Dallas, Texas 75201. A current copy of the Policy on Stockholder-Director Communications is available on the Governance section of our website at www.bldr.com.

All communications received will be opened by the office of our General Counsel for the sole purpose of determining whether the contents represent a message to our directors. Any contents that legitimately relate to the business and operation of the Corporation and that are not in the nature of advertising, promotions of a product or service, patently offensive material, charitable requests, repetitive materials, or promotions of a political or similar agenda will be forwarded promptly to the addressee.

Auditor Services Pre-Approval Policy

Our Audit and Non-Audit Services Pre-Approval Policy, available on the Governance section of our website at www.bldr.com, defines the principles and procedures followed by the Audit Committee in pre-approving audit and non-audit services performed by the Corporation’s independent registered public accounting firm.

Policy Regarding Hedging and Pledging

The Corporation’s Insider Trading Policy, which is applicable to all directors, executive officers, and other employees, provides that such persons may not trade in options, warrants, puts and calls, or similar instruments on Corporation securities, hold Corporation securities in margin accounts, or sell Corporation securities “short” without the prior written approval of the Corporation’s General Counsel. Such persons may not enter into any other hedging transaction involving Corporation securities or pledge Corporation securities as collateral for a loan or other obligation without the prior written approval of the Corporation’s General Counsel.

Corporate Governance

2021 Sustainability Highlights

Our values are at the center of everything we do: safety; people; integrity; customers; excellence. From the boardroom to the jobsite, they define our culture and guide our priorities, decisions and actions. Our sustainability strategy and goals are reviewed and approved by our executive management team, with the Nominating and Corporate Governance Committee tasked with overseeing management’s efforts on these matters, including sustainability, human rights, labor, diversity, health and safety, supply chain and community, to enhance shareholder value.

Below are some highlights with respect to our sustainability efforts in 2021.

Publishing Our First Sustainability Report

We have committed to publish prior to the 2022 Annual Meeting the first sustainability report for Builders FirstSource following the close of the merger with BMC in 2021.

The sustainability report will apply the Sustainability Accounting Standards Board (SASB) and Task Force on Climate-Related Financial Disclosures (TCFD) frameworks.

Team Member Safety, Engagement and Diversity

In 2021, we delivered an 18% reduction in recordable injuries across the Company, resulting in a recordable injury rate of 2.84 and beating our 10% reduction goal. We have set another 10% annual safety improvement target for 2022, and this target is a component of executive and employee compensation. The Company has also implemented many processes aimed at protecting our associates during the COVID-19 pandemic, including providing personal protective equipment and encouraging remote work where appropriate.

Our dedicated internal training and development team supports the continuous professional development of our Team Members by identifying and addressing current and future training needs.

As part of our diversity, equity and inclusion strategy, in 2021 we engaged our Team Members through a DEI survey to develop our key priorities. To drive these priorities, we have launched required trainings for all Team Members, including the training modules “Unconscious Bias” and “Diversity Face to Face.” The following table sets forth the gender and ethnic diversity composition of our Team Members in 2021.

2021 Gender and Ethnic Diversity by Function

	All Team Members	Executives	Corporate	Field Ops	Field Management
Male	84%	89%	67%	85%	83%
Female	16%	11%	33%	15%	17%
Ethnically Diverse	51%	13%	29%	55%	24%

Enabling Greener, More Efficient Construction

In sourcing our materials, Builders FirstSource is committed to partnering with those companies that share our values on environmental sustainability and responsibility towards our planet. Approximately 90% of the wood we purchased in 2021 was certified sustainable by the Sustainable Forestry Initiative (“SFI”). Our top suppliers represent industry leaders in actively promoting, supplying, or collaborating with environmentally conscious organizations including SFI, the Forest Sustainability Counsel (“FSC”), ISO 14001, and the Programme for the Endorsement of Forest Certification (“PEFC”). The certification of SFI is accepted by the U.S. Green Building Council in its Leadership in Energy and Environmental Design (“LEED”) rating system. We offer a broad range of energy-efficient and sustainable-certified products, including SFI wall panels, lumber, and Energy Star^® qualified windows and doors. The Company has also enacted a Responsible Supply Chain Policy outlining that it expects all of its suppliers to buy materials from socially responsible sources in compliance with Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

Corporate Governance

Our products enable our partners to build more sustainably and efficiently. Our READY-FRAME^® computerized, precise pre-cut, labeled framing bundles enable crews to build faster, safer, and with less waste. READY-FRAME^® enables construction up to 20% faster and can deliver a 39% increase in productivity per person hour. It can require 60% less cutting and 27% less ladder time, reducing injury risk for a safer and cleaner jobsite. READY-FRAME^® also significantly reduces the amount of material sent to landfill, with up to two-thirds fewer dumpsters, meaning less waste and lower disposal costs.

Representatives at Levy Partnership, a New York City consulting firm that specializes in sustainable building, analyzed all of the data collected from construction using our READY-FRAME^® products and figured savings of approximately 2,500 pounds of carbon per completed house frame and 7.8 fewer trees harvested per home. These savings have resulted in nearly 3.4 million trees saved since January 1, 2019 and another 1,500 fewer pounds of carbon emissions per home as a result of less mill time.

As part of our climate change commitment, we have been working to harmonize the combined Builders FirstSource and BMC systems to collect and report our energy use and greenhouse gas (“GHG”) emissions data. We plan to report the operational emissions from our largest sites this year and company-wide Scope 1 and 2 GHG emissions in 2023.

Sustainability Ambitions

As we continue to drive sustainability initiatives following the Merger, we are working towards a comprehensive plan to reduce our GHG emissions. As part of our comprehensive plan to reduce our GHG, we are committed to taking the following steps:

• Quantifying and disclosing our Scope 1 and 2 greenhouse gas emissions in 2023. We are actively engaging in efforts to quantify and disclose Scope 3 greenhouse gas emissions in the near term.

• Assessing setting a net-zero science-based target with the Science Based Targets initiative (“SBTi”). As per the SBTi rules, after committing to set a science-based target, the Corporation would have two years to develop, submit, and set a target through SBTi.

• Integrating zero emission vehicles into our fleets, and we expect that our operations will become increasingly energy efficient, especially with respect to Scope 1 emissions.

• Prioritize sourcing wood from SFI or FSC certified vendors, particularly for wood from Canadian boreal forests and temperate rainforests.

We are strongly committed to meeting the challenges of reducing our greenhouse gas emissions and look forward to continuing our sustainability efforts, and communicating these efforts to shareholders, in the months and years ahead. We will continue to engage with our shareholders to solicit their perspectives on our sustainability efforts, and appropriately integrate the feedback provided by our shareholders as our policies, practices and disclosures evolve.

Our operations are internally organization into three geographic operation divisions—West, Central, and East. In 2021, Scott L. Robins served as President of our operations located in the West Division. As such, his compensation was aligned to reflect the performance of the division he oversees.

The remaining NEOs, David E. Flitman, M. Chad Crow, Peter M. Jackson, Michael A. Farmer, and Timothy D. Johnson, were corporate leaders in 2021. As such, their compensation was aligned to reflect overall company performance.

Executive Summary

In early 2021, our Board of Directors tasked our executive team with several priority objectives for the year. The Compensation Committee believes that the executive team substantially accomplished most of these objectives, which are summarized as follows:

2021 Priority Objectives	2021 Achievements
Continue to accelerate growth and stockholder value through strategic acquisitions	Completed five lumber and building material acquisitions, which continued the expansion of our geographical footprint in critical markets
Adjusted EBITDA(1) (defined below) equal to or greater than $1.3 billion target in our 2021 Annual Operating Plan (“2021 AOP”)	Achieved record Adjusted EBITDA of $3.1 billion (an increase of 186% over 2020)
Reduction of net debt/Adjusted EBITDA leverage ratio (1.7x at December 31, 2020)	Net debt/Adjusted EBITDA leverage ratio of 1.0x at December 31, 2021
Return on invested capital (“ROIC”) growth of 12.5% or more above 2020 pro-forma ROIC	Achieved ROIC growth of 233% above 2020 pro-forma ROIC
Expansion of manufacturing capacity for value-added products	•  Opened two additional truss facilities and acquired eleven facilities through acquisitions •  Improved product throughput in our manufacturing facilities with efficiency investments and lean practice deployment
Reduction of Recordable Incident Rate (“RIR”) of 3.10 or lower	RIR of 2.84 in 2021
Provide industry-leading digital solutions for our customers	Acquired two companies specializing in software solutions and services, underscoring our commitment to enhancing digital offerings for our customers and to the broader homebuilding industry
Working Capital as a Percentage of Sales equal to or less than 8.5% target in our 2021 AOP	Working Capital as a Percentage of Sales was 10.1%, which was below target largely due to commodity price volatility

With our financial and operational objectives in mind, our Compensation Committee designed the 2021 executive compensation program, which included the following components:

• Salary increases for all NEOs except M. Chad Crow, who retired as Chief Executive Officer on April 1, 2021.

• The Compensation Committee implemented a performance-based annual incentive bonus program for all corporate managers, including our NEOs (the “2021 Corporate Incentive Plan” or the “2021 Plan”). As described in more detail below, the 2021 Corporate Incentive Plan provided our NEOs with an opportunity to earn an annual incentive based on (i) the amount of Adjusted EBITDA generated by the Company in 2021, (ii) the level of working capital as a percentage of sales managed by the Company for the year, and (iii) a reduction of RIR during the year. Because of management’s significant outperformance of these financial and operational objectives, all of our NEOs received 2021 annual incentive awards of 163.5% of their respective target bonus opportunities under the 2021 Plan.

• The Compensation Committee annually considers the grant of equity incentive awards to our executive team in order to further align their financial interests with those of our stockholders. Effective in March 2021, the Compensation Committee issued new equity incentive awards to key managers, including our NEOs, in order to promote retention and to incentivize management to maximize the financial performance of our Company. The equity incentive awards consisted of both performance-based restricted stock units (“PSUs”) and time-vesting restricted stock units (“RSUs”). The PSUs vest based on the achievement of annual and three-year ROIC goals set by the Compensation Committee, with a performance modifier based on total shareholder return (“TSR”) of the Company measured over the three-year performance period, as described below. The Compensation Committee selected ROIC as the primary performance metric for the PSUs in order to better align management’s financial interest with those of our stockholders over the longer term.

1. Company provided a reconciliation of these non-GAAP financial measures to the comparable GAAP financial measures in its Form 8-K filed with the Securities and Exchange Commission on March 1, 2022.

Executive Compensation and Other Information

Compensation Principles

Our executive compensation program has been designed to provide a total compensation package that allows us to attract, retain, and motivate executives who have the talent to capably manage our business. Our executive compensation program has historically been guided by several key principles:

• Provide total compensation opportunities at levels that are competitive for comparable positions at companies with whom we compete for talent.

• Provide incentives to our executive officers to achieve key financial objectives set by the Board of Directors.

• Provide an appropriate mix of fixed and variable pay components to establish a “pay-for-performance” oriented compensation program.

• Align the financial interests of executives with stockholder interests by providing significant compensation opportunities in the form of equity awards.

• Emphasize direct pay components, such as cash and equity.

Key Executive Compensation Practices

The following is a summary of our executive compensation practices that we believe drive performance and align our executives’ interests with the interests of our stockholders:

• We strive to provide balanced pay opportunities for our executives, consisting of an appropriate mix of cash and equity, annual and longer-term incentives, and fixed and variable pay.

• Our annual incentive plan is performance-based, and payouts are subject to minimum thresholds based on performance targets and appropriate caps.

• We have a compensation clawback policy that allows the Company, in the event of a restatement of its financial results, to recover excess amounts erroneously paid to executive officers under certain circumstances.

• Our incentive plan provides for “double-trigger” vesting for equity awards upon a change in control.

• We do not provide any tax gross-ups.

• Our insider trading policy prohibits employees and directors from engaging in pledging or hedging activities involving Company stock.

Consideration of Most Recent Advisory Stockholder Vote on Executive Compensation

At the annual meeting of stockholders on June 15, 2021, over 95% of the shares represented and entitled to vote on the proposal at the annual meeting were voted to approve the compensation of the Company’s named executive officers, as discussed and disclosed in the 2021 Proxy Statement. The Board and the Compensation Committee appreciate and value the views of our stockholders. In considering the results of this advisory vote on executive compensation, the Compensation Committee concluded that the compensation paid to our named executive officers and the Company’s overall pay practices enjoy strong stockholder support.

Going forward, future advisory votes on executive compensation will serve as an additional tool to guide the Board and the Compensation Committee in evaluating the alignment of the Company’s executive compensation program with the interests of the Company and its stockholders.

2021 Executive Compensation Process

Role of the Compensation Committee. Under its charter, the Compensation Committee is responsible for (i) reviewing and approving our executive compensation program, (ii) administering our long-term incentive plan, (iii) reviewing the Company’s compensation programs in light of best practices and good corporate governance, (iv) reviewing and approving the Compensation Discussion and Analysis section of our proxy statement, and (v) monitoring the Company’s compensation-related risk. As part of its evaluation process relating to NEO compensation, the Compensation Committee reviewed information compiled by our compensation consultant as well as data compiled by the Company. At meetings held in November and December 2020 and February 2021, the Compensation Committee approved, and recommended to our Board of Directors for its ratification, the 2021 executive compensation program for all post-Merger executive officers except Mr. Flitman, which included setting 2021 base salaries, approving the 2021 Corporate Incentive Plan, and approving equity incentive awards to be granted in 2021. The Compensation Committee reviewed and approved Mr. Flitman’s compensation arrangement in August 2020 in connection with the Merger.

Role of Executives. Our CEO and General Counsel, as well as members of our Legal, Human Resources, and Finance Departments, assisted the Compensation Committee and the Board in gathering the information needed for their respective reviews of our 2021 executive compensation program. The Compensation Committee and the Board also considered our CEO’s recommendations for our executive officers (other than himself) with respect to the 2021 executive compensation program.

Role of the Board of Directors. The Board of Directors is responsible for reviewing and ratifying the decisions and recommendations of the Compensation Committee regarding our executive compensation program. In March 2021, after considering the decisions and recommendations of the Compensation Committee, the Board ratified the 2021 executive officer compensation program.

Role of Compensation Consultants. Under its charter, the Compensation Committee is authorized to engage independent outside advisors to assist it in discharging its responsibilities relating to executive compensation. The Compensation Committee has retained Meridian Compensation Partners, LLC (“Meridian”) to perform a comprehensive review of our executive compensation program and to conduct market compensation comparisons for our executive officers in order to assist the Compensation Committee in designing our 2021 executive compensation program. The Compensation Committee determined that Meridian is independent under applicable SEC rules. While the Compensation Committee takes Meridian’s advice on compensation matters into consideration, the Compensation Committee has the authority and responsibility to make final decisions on our executive compensation program.

Market Comparisons. The Compensation Committee periodically examines the competitiveness of our executive compensation program to determine how our compensation levels compare to our overall philosophy and target markets. The Compensation Committee has retained Meridian to assist in updating our Peer Group (defined below) list for purposes of reviewing market compensation comparisons. In our case, peer selection is somewhat difficult due to the lack of publicly-traded companies with whom we compete and the absence of available data for privately-held competitors. We revised our Peer Group in November 2020 to align more closely with the size of our company after the Merger. We removed six companies from the 2020 peer group (including BMC Stock Holdings, Inc.) and added six new companies, resulting in a peer group of 18 companies.

Elements of our Compensation Program

Components of Compensation. Our executive compensation program for 2021 consists of the following elements for our NEOs:

	Plan	Purpose	Relevant Performance Metric and Description
	Base Salary	To provide fair and competitive compensation for individual performance and level of responsibility of position held.	Individual Performance
	2021 Corporate Annual Incentive Plan	To provide performance-based annual cash awards for Company and divisional performance to motivate and reward key employees for achieving our short-term business objectives and drive performance.	Mix of metrics, including: •  Adjusted EBITDA •  Working Capital •  Safety
	2021 Long-Term Incentive Plan: Performance Stock Units (50%) (“PSUs”)	To provide performance-based equity compensation in the form of restricted stock units to maximize stockholder value and retain key employees.	Awards vest at the end of a three-year performance period based on achievement of goals tied to return on invested capital, +/- 10% TSR modifier compared to Peer Group.
	2021 Long-Term Incentive Plan: Restricted Stock Units (50%) (“RSUs”)	To enhance the program’s ability to retain participants and drive long-term behavior by allowing for time-based awards.	The RSUs are time-vested awards that generally vest in equal annual installments on the first three anniversaries of the applicable grant date, subject to the award recipient’s continued employment by the Company.

The Compensation Committee generally seeks to provide total direct compensation opportunities to our executive officers, consisting of base salary, target annual cash incentive, and long-term equity award value (“TDC”), at approximately the median of the market or below, but individual market positioning may be more or less than median for a variety of reasons such as Company and individual performance, experience, tenure, retention concerns, internal alignment, unique aspects of their role relative to external benchmarks, or other relevant factors. Based on the market comparison surveys conducted by Meridian, the 2021 TDC target opportunities established for our executive officers were consistent with this compensation philosophy and were within the following percentile ranges relative to our Peer Group:

Name	Peer Group Range
David E. Flitman	Approximately 50%
M. Chad Crow	25-50%
Peter M. Jackson	Approximately 50%
Scott L. Robins	Approximately 50%
Michael A. Farmer	25-50%
Timothy D. Johnson	25-50%

Builders FirstSource, Inc.  |  2022 Proxy Statement    35

Executive Compensation and Other Information

The following sections describe in greater detail each of the elements of our executive compensation program, why they were selected, and how the amounts of each element were determined.

Base Salary

Base salary is designed to compensate the executive officers for their roles and responsibilities and to provide a stable and fixed level of compensation that serves as a retention tool throughout the executive’s career. In determining base salaries, we generally consider each executive’s role and responsibilities, unique skills, the salary levels for similar positions in our Peer Group companies, and internal pay equity.

The salaries approved for our executive officers are listed below and were within the following percentage ranges of our Peer Group:

Name	2020 Salary	2021 Salary	Increase	Peer Group Range
David E. Flitman	N/A	$    1,050,000	N/A	Approximately 50%
M. Chad Crow	$        950,000	$        950,000	0.0%	Approximately 25%
Peter M. Jackson	$        550,000	$        625,000	13.6%	25-50%
Scott L. Robins	$        500,000	$        525,000	5.0%	Approximately 50%
Michael A. Farmer	N/A	$        425,000	N/A	<25%
Timothy D. Johnson	N/A	$        450,000	N/A	<25%

The 2020 salaries of Messrs. Flitman, Farmer, and Johnson are not included because they were not employed by the Company until the Merger Effective Date.

Annual Cash Incentives

We provide annual cash incentive opportunities to our executive officers that are designed to reward the achievement of financial results measured over the current fiscal year. The Compensation Committee selects the financial performance goals applicable to the annual incentive program, which are based on key financial metrics that are deemed critical to the Company’s near-term success.

2021 Corporate Annual Incentive Plan. For 2021, the Compensation Committee decided to implement an annual cash incentive program for our corporate office managers, including our NEOs. Under the 2021 Corporate Incentive Plan, a target bonus opportunity for each participant was set as a percentage of base salary determined by their position. Actual bonus amounts that could be earned by our NEOs ranged from 0% (for performance below threshold levels) to a maximum of 200% (for performance above target levels) of their respective target bonus amounts.

For 2021, the Compensation Committee set the target bonus opportunity for Mr. Flitman at 125% of his base salary and for each other NEO at 100% of such NEO’s base salary, as provided in each NEO’s employment agreement. Because Mr. Crow retired as CEO on April 1, 2021, he did not participate in the 2021 Corporate Incentive Plan.

Under the 2021 Plan, 90% of an NEO’s bonus potential was based solely on the Company’s achievement of financial goals in 2021, while the remaining 10% was based on achievement of a safety-focused Recordable Incident Rate (“RIR”) target.

Specifically, the 2021 Corporate Incentive Plan provided for bonuses for our NEOs based on the following metrics:

Metric	Weighting
Adjusted EBITDA	70%
Working Capital as a Percentage of Sales	20%
Safety Goal	10%

36    Builders FirstSource, Inc.  |  2022 Proxy Statement

Executive Compensation and Other Information

The Compensation Committee chose Adjusted EBITDA (as defined below) and Working Capital as a Percentage of Sales as the financial performance goals under the 2021 Plan because it believes that these metrics provide an effective incentive to maximize financial performance and closely align management awards with Company performance and the financial interests of stockholders.

Adjusted EBITDA Metric. The 2021 Plan provided that 70% of the bonuses for Messrs. Flitman, Jackson, Farmer, and Johnson and 35% of the bonus for Mr. Robins were based on the amount of Adjusted EBITDA earned by the Company for the year as compared to the budgeted target amount of Adjusted EBITDA included in the Company’s 2021 AOP. The other 35% of the Adjusted EBITDA bonus component for Mr. Robins was based on the amount of Adjusted EBITDA earned in 2021 by the West Division, for which Mr. Robins was operationally responsible, as compared to the 2021 AOP. “Adjusted EBITDA” is calculated as earnings before interest, taxes, depreciation, and amortization, as adjusted for other non-recurring and/or non-cash items.

The 2021 Plan provided that no bonuses would be earned under the Adjusted EBITDA component unless the Company achieved more than 80% of its Adjusted EBITDA target included in the 2021 AOP, as set by the Board of Directors.

The following grid outlines the scaled bonus payments for this component of the 2021 Plan based on the Company’s Adjusted EBITDA performance in 2021. Any performance between levels was calculated based on the linear interpolation between such levels.

Adjusted EBITDA Targets (70% Weighting)
Target Levels	Percentage of Target Earned
Under $1.03 billion	0%
$1.03 billion	25%
$1.09 billion	50%
$1.29 billion	100%
$1.55 billion	maximum 200%

The Adjusted EBITDA target included in the 2021 AOP was $1.3 billion. As noted above, the Company achieved Adjusted EBITDA of $3.1 billion for fiscal year 2021, 200% above the AOP target. Additionally, Adjusted EBITDA for the West Division for fiscal year 2021 was 200% above target. The following chart shows the 2021 performance of each NEO under the Adjusted EBITDA component of the 2021 Plan.

Adjusted EBITDA Actual Performance (70% Weighting)
Name	Percentage of Target Earned
David E. Flitman	200%
M. Chad Crow	N/A
Peter M. Jackson	200%
Scott L. Robins	200%
Michael A. Farmer	200%
Timothy D. Johnson	200%

The Adjusted EBITDA-related bonus amounts paid to our NEOs for 2021 are included in the “Non-Equity Incentive Plan Compensation” column of the “Summary Compensation Table” in this Proxy Statement.

Working Capital Metric. Working capital is a measurement of the Company’s operating liquidity and includes funds invested in accounts receivable, product inventories, and accounts payable. The Compensation Committee set the Working Capital as a Percentage of Sales target under the 2021 Plan for the NEOs at 8.5%, because that matched the Company’s budgeted working capital target included in the 2021 AOP. This working capital target included both working capital managed at the corporate level (e.g., checks outstanding, corporate accruals, and prepaid assets) and regional working capital results. If the actual working capital percentage for the year was lower than the target, the bonus payment would increase. If the actual working capital percentage was higher than

Builders FirstSource, Inc.  |  2022 Proxy Statement    37

Executive Compensation and Other Information

the target, the bonus payment would decrease. Under the 2021 Plan, the Company had to achieve at least 80% of the 2021 working capital target (or a maximum of 10.2% Working Capital as a Percentage of Sales) to trigger any payment.

The following grid outlines the scaled bonus payment for this component of the 2021 Plan for the actual Working Capital percentage achieved by the Company for the year. Any performance between levels was calculated based on the linear interpolation between such levels.

Working Capital Targets (20% Weighting)
Target Levels	Percentage of Target Earned
Above 10.20%	0%
10.20%	25%
9.78%	50%
8.50%	100%
6.80% or below	maximum 200%

The Company achieved a 10.1% Working Capital as a Percentage of Sales result for 2021, which was above its budget threshold. For purposes of this component of the 2021 Plan, the performance of all NEOs was determined based on results of the entire Company. The following chart shows the 2021 performance of each NEO under the Working Capital as a Percentage of Sales component of the 2021 Plan.

Working Capital Actual Performance (20% Weighting)
Name	Percentage of Target Earned
David E. Flitman	29%
M. Chad Crow	N/A
Peter M. Jackson	29%
Scott L. Robins	29%
Michael A. Farmer	29%
Timothy D. Johnson	29%

The working capital-related bonus amounts paid to our NEOs for 2021 are included in the “Non-Equity Incentive Plan Compensation” column of the “Summary Compensation Table” in this Proxy Statement.

Safety Component. The Compensation Committee believes that the safety of the Company’s employees is a critical component of the Company’s success and one of the Company’s core values. Therefore, in addition to the Adjusted EBITDA and Working Capital metrics described above, the Compensation Committee decided that the 2021 Plan should include the reduction of the Company’s RIR as a component of our NEO bonus program. For 2021, the Compensation Committee set a 3.10 RIR target to trigger any payment under the 2021 Plan.

The following grid outlines the scaled bonus payment for this component of the 2021 Plan for the RIR achieved by the Company for the year. Any performance between levels was calculated based on the linear interpolation between such levels.

RIR Targets (10% Weighting)
Target Levels	Percentage of Target Earned
Above 3.10 RIR	0%
3.10 RIR	100%
2.76 RIR or below	maximum 200%

The Compensation Committee, in consultation with our CEO, set this objective on a company-wide basis. For purposes of this component of the 2021 Plan, the performance of all NEOs was determined based on the RIR target for the overall performance of the Company as a whole during 2021. The Company’s RIR in 2021 was

38    Builders FirstSource, Inc.  |  2022 Proxy Statement

Executive Compensation and Other Information

2.84. The following charts show the 2021 performance of each NEO against the RIR target set by the Compensation Committee.

RIR Actual Performance (10% Weighting)
Name	Percentage of Target Earned
David E. Flitman	177%
M. Chad Crow	N/A
Peter M. Jackson	177%
Scott L. Robins	177%
Michael A. Farmer	177%
Timothy D. Johnson	177%

Overall Payout. As a result of the Company’s 2021 financial performance, as well as the substantial achievement by our executive team of the operational objectives described above, our NEOs received aggregate bonuses as follows:

Name	2021 Target Bonus (percentage of salary)	2021 Target Amount	Percentage of 2021 Target      Bonus Earned
David E. Flitman	125%	$    1,312,500	163.5%
M. Chad Crow	N/A	N/A	N/A
Peter M. Jackson	100%	$        625,000	163.5%
Scott L. Robins	100%	$        525,000	163.5%
Michael A. Farmer	100%	$        425,000	163.5%
Timothy D. Johnson	100%	$        450,000	163.5%

The bonus amounts paid to our NEOs for 2021 are included in the “Non-Equity Incentive Plan Compensation” column of the “Summary Compensation Table” in this Proxy Statement.

Long-Term Equity Incentives

A key component of our executive compensation program consists of rewards for long-term strategic accomplishments and enhancement of long-term stockholder value through the use of equity-based incentives. We believe that long-term incentive compensation performs an essential role in attracting and retaining talented executives and providing them with incentives to maximize stockholder value. Restricted stock unit awards and stock options have historically been the primary long-term incentive vehicles that we use in our executive compensation program. In 2021, the Compensation Committee decided to grant performance-based restricted stock units (“PSUs”) and time-vesting restricted stock units (“RSUs”), consistent with our practice in recent years. These award vehicles were selected by the Compensation Committee due to their retention value and the performance link to our stock price.

Effective March 15, 2021, the Compensation Committee and the Board approved equity awards to key managers, including our NEOs other than M. Chad Crow, in order to promote retention and provide incentive to management to maximize the Company’s financial performance over an extended period. 50% of the awards were RSUs and 50% were PSUs, as described below:

• Time-Vesting. The RSUs vest over three years in equal annual installments.

• Performance-Vesting. The PSUs vest in full on the third anniversary of the grant date based on the Company’s achievement of annual and three-year ROIC targets, with the payout subject to a modifier in the event that the Company’s TSR significantly outperforms or underperforms the TSR of our Peer Group over the three-year measurement period.

The Compensation Committee chose the foregoing performance metrics for the PSU grants to each NEO other than M. Chad Crow in order to (i) incentivize our executive team to grow the Company’s ROIC in conjunction with the Adjusted EBITDA and Working Capital financial metrics utilized in our 2021 Corporate Incentive Plan and

Builders FirstSource, Inc.  |  2022 Proxy Statement    39

Executive Compensation and Other Information

(ii) ensure that our NEOs’ financial interests are aligned with those of our stockholders over an extended period. The Compensation Committee determined that 50% of the award to each NEO should be RSUs that vest based on continued employment with the Company, because it views retention of key management talent as a critical function of our long-term equity incentive program.

The Compensation Committee determined that it was critical to retain key legacy BMC executives following the Merger. The Compensation Committee therefore granted to Mr. Flitman a one-time sign-on RSU award with a target value of $2,000,000 as set forth in his Employment Agreement and to Messrs. Farmer and Johnson a one-time sign-on RSU award with a target value of $1,500,000, in each case that vest in three equal installments on March 15, 2022-2024 (the “BMC Sign-On RSU Awards”).

The target value of the RSU and PSU awards made to each executive officer for 2021 was as follows:

Name	Value of Award
David E. Flitman	$    6,800,000
M. Chad Crow	N/A
Peter M. Jackson	$    1,500,000
Scott L. Robins	$       800,000
Michael A. Farmer	$    2,075,000
Timothy D. Johnson	$    2,000,000

Excluding the BMC Sign-On RSU Awards, the RSU awards to each of our executive officers were set between the 25^th percentile and the median of the market. The restricted stock unit awards granted to our NEOs in 2021 are reflected in the “2021 Grants of Plan-Based Awards” table later in this Proxy Statement.

Performance Measurement – ROIC Component. The Compensation Committee believes that ROIC is an effective metric to measure the Company’s efficiency at allocating capital and generating returns for stockholders.

In establishing a long-term performance goal, the Compensation Committee and management believe it is appropriate to incentivize immediate and continued performance against pre-established goals. Additionally, as we operate in a cyclical industry, it is important to mitigate large swings in performance (either up or down). As such, the ROIC incentive plan was designed to reward for three individual performance years based on continual improvement from prior year results as well as the achievement against a pre-set three-year objective. This provides the appropriate balance between year-over-year improvement and long-term sustained performance.

ROIC is defined as:

                                         Adjusted EBIT                                        

(Total Debt + Finance and Operating Lease Obligations

– Cash and Cash Equivalents + Stockholders’ Equity) *

*  Calculated based on trailing four quarter average for each of the annual tranches

ROIC performance is measured over four separate measurement tranches: an annual ROIC measurement for each of 2021-2023 and a cumulative ROIC measurement for performance over the three-year period.

Measurement Tranche	Weight
2021 ROIC	25%
2022 ROIC	25%
2023 ROIC	25%
3-year Avg. ROIC (2021-2023)	25%

For each tranche, payout would begin at 50% at the minimum performance goal, would increase to 100% at the full payout target, and would be capped at 200% at the maximum target. There will be no payout for a tranche

40    Builders FirstSource, Inc.  |  2022 Proxy Statement

Executive Compensation and Other Information

where the minimum goal is not met. Payout percentages between targets would be determined by linear interpolation. The payout scale is set forth in the following table.

Tranche	Minimum (50% Payout)	Full Payout (100% Payout)	Maximum (200% Payout)
2021 ROIC	2020 Pro Forma ROIC	2020 Pro Forma ROIC + 12.5% Improvement	2020 Pro Forma ROIC + 25% Improvement
2022 ROIC	2021 Actual ROIC	2021 Actual ROIC + 12.5% Improvement	2021 Actual ROIC + 25% Improvement

3-year Avg. ROIC	2020 Pro Forma ROIC + 12.5% Improvement	3-year Avg. Minimum Target + 12.5% Improvement	3-year Avg. Minimum Target + 25% Improvement

As shown in the above grid, for each of the annual tranches, (i) minimum payout requires hitting the actual ROIC performance for the prior year, (ii) target payout is based on achieving the actual ROIC performance for the prior year plus a 12.5% improvement, and (iii) maximum payout would require generating a 25% improvement over the actual ROIC performance for the prior year. For the three-year average tranche, (i) the minimum payout threshold is a 12.5% improvement over 2020 pro forma ROIC, (ii) the target payout is a 12.5% increase over that minimum target, and (iii) the maximum target is a 25% increase above the minimum payout threshold. 2020 ROIC is calculated on a combined pro forma basis for the Company and BMC.

As mentioned above, the Company’s TSR measured over the three-year vesting period of the awards will be used as a modifier rather than a primary metric. If the Company’s TSR is in the bottom two of the selected peer group of 18 companies, the payout based on the ROIC percentage will be reduced by 10%. If the Company’s TSR is in the top two of that group, the payout based on the ROIC percentage will be increased by 10%. For this purpose, the peer group is identical to the Peer Group used for executive compensation and shown earlier in this Proxy Statement.

Any payouts generated by the 2021 and 2022 tranches would be subject to additional time-based vesting requirements such that they would vest in each of the annual 2021, 2022, and 2023 tranches upon the conclusion of the three-year performance period based on achievement of the ROIC and TSR performance goals for each tranche, provided that our NEOs remain employed by the Company for the full three-year period of the grant.

Executive Benefits and Perquisites

The Company generally does not provide its executive officers with perquisites or special benefits that are not available to other employees. Company-provided air travel for officers is for business purposes only. The Company’s health care, insurance, 401(k) plan (including Company matching contributions), and other welfare and employee-benefit programs are the same for all eligible employees, including the NEOs, except that employees making over $100,000 annually make higher monthly contributions for their health insurance benefits and certain senior officers are eligible for reimbursement of executive physicals.

The benefits provided to our named executive officers during 2021 are set forth in the “All Other Compensation” column of the “Summary Compensation Table” later in this Proxy Statement.

Post-Termination Compensation

The Board believes that severance benefits are necessary in order to attract and retain the caliber and quality of executive that the Company needs in its most senior positions.

The Company had entered into employment agreements with each of its executive officers. The terms of these agreements are described under the caption “Employment Agreements” later in this Proxy Statement. These agreements provide the Company with protection in the form of restrictive covenants, including non-competition, non-solicitation, and confidentiality covenants. The Board considered the advisability of using employment

Builders FirstSource, Inc.  |  2022 Proxy Statement    41

Executive Compensation and Other Information

agreements with its executive officers and determined that they are in the best interests of the Company insofar as they permit the Company to achieve its goals of attracting and retaining the best possible executive talent while obtaining post-employment non-competition and non-solicitation covenants from executive officers.

Under the terms of their employment agreements in effect for 2021, our executive officers are entitled to certain severance benefits in the event their employment is terminated by the Company without “cause” or by the NEO under certain circumstances, as described in the employment agreements. For Mr. Flitman, these severance benefits include (i) salary continuation for a period of 18 months if terminated without “cause,” (ii) continuation of health and welfare benefits during this period, and (iii) a payment equal of 150% of his annual target bonus if he is terminated without “cause.” For the other NEOs, these severance benefits include (i) salary continuation for a period of one year, (ii) continuation of health and welfare benefits during this period, and (iii) a payment equal of 100% of his annual target bonus. These severance benefits are described under the caption “Potential Payments Upon Termination or Change in Control” later in this Proxy Statement.

As disclosed above (and previously announced), M. Chad Crow stepped down as President as of the Merger Effective Date, but continued to serve as CEO until April 1, 2021, at which time he retired. Mr. Crow entered into a consulting agreement with the Company pursuant to which Mr. Crow will provide executive-level advisory consulting services to the Company for two years after the date of his retirement. Under the consulting agreement, Mr. Crow’s outstanding restricted stock unit awards will continue to remain outstanding and vest in accordance with the terms of the original award agreements, subject to Mr. Crow’s continued service to the Company under the consulting agreement.

Retirement / Post-Employment Benefits

The Company does not provide any retirement programs or benefits to its NEOs other than its 401(k) program, which is available to all employees.

1. Reflects the aggregate grant date fair value of restricted stock unit awards, which for 2021 included both time-based vesting and performance-based vesting RSUs. The fair value of these awards was determined in accordance with the Compensation – Stock Compensation topic of the Financial Accounting Standards Board Accounting Standards Codification. The grant date fair value of time-based vesting RSUs was equal to the closing price of our Common Stock on the grant date. The grant date fair value of the performance-based vesting RSUs, utilizing an annual return on invested capital (“ROIC”) measurement for each of 2021-2023 individually and a cumulative ROIC measurement for performance over that three-year period, and subject to a total shareholder return modifier, was determined using the Monte Carlo simulation model, which is based on a number of factors. If achievement of the highest level of performance conditions is assumed, the grant date fair value of the awards to Messrs. Flitman, Jackson, Robins, Farmer, and Johnson would increase by $2,930,813, $915,849, $488,453, $351,028, and $305,235, respectively. The weighted average assumptions used in determining the grant date fair value of these awards are set forth in Note 2, “Summary of Significant Accounting Policies,” in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2021.

Flitman, Farmer, and Johnson each received a 50% match for his contributions up to 6% of his annual compensation in 2021, subject to a maximum match pursuant to Internal Revenue Service regulations. Messrs. Jackson and Robins received a 40% match for his contribution up to 5% of his annual compensation in 2021, subject to a maximum match pursuant to Internal Revenue Service regulations.

4. Mr. Flitman was elected as President effective January 1, 2021 and as Chief Executive Officer effective April 1, 2021.

5. Mr. Crow retired as President effective January 1, 2021 and as Chief Executive Officer effective April 1, 2021.

1. Represents threshold, target, and maximum payout levels for 2021 performance under the 2021 Corporate Annual Incentive Plan, which was established under the 2014 Incentive Plan. The threshold amount for each of Messrs. Flitman, Jackson, Robins, Farmer and Johnson represents the minimum amount that could be paid under the 2021 Corporate Annual Incentive Plan, which would occur if the Company only achieved the minimum payout under the Working Capital as a Percentage of Sales metric. For more information regarding the 2021 Corporate Annual Incentive Plan, see the discussion in the “Compensation Discussion and Analysis” section above.

2. Reflects awards of performance-based vesting RSUs under the 2014 Incentive Plan. Each award vests on the third anniversary of the grant date based on four separate performance measures: an annual return on invested capital (“ROIC”) measurement for each of 2021-2023 and a cumulative ROIC measurement for performance over that three-year period. For each of the annual tranches, (i) minimum payout requires achieving the actual ROIC performance for the prior year, (ii) full payout requires achieving the actual ROIC performance for the prior year plus a 12.5% improvement, and (iii) maximum payout requires achieving a 25% improvement over the actual ROIC performance for the prior year. When used as a target to calculate 2021 ROIC, actual ROIC for 2020 will be calculated on a combined pro forma basis for the Corporation and BMC. For the three-year average tranche, (i) minimum payout requires achieving pro forma 2020 ROIC plus a 12.5% improvement, (ii) the full payout target is a 12.5% increase over that minimum target, and (iii) the maximum target is a 25% increase above the minimum payout threshold. Additionally, the awards are subject to a total shareholder return (“TSR”) modifier. If the Corporation’s TSR is in the bottom two of a selected peer group, the payout based on the ROIC percentage will be reduced by 10%. If the Corporation’s TSR is in the top two of the selected peer group, the payout based on the ROIC percentage will be increased by 10%.

3. Reflects the aggregate grant date fair value of restricted stock unit awards granted in 2021. The fair value of these awards was determined in accordance with the Compensation — Stock Compensation topic of the Financial Accounting Standards Board

44    Builders FirstSource, Inc.  |  2022 Proxy Statement

Executive Compensation and Other Information

Accounting Standards Codification. For time-based vesting RSUs, the grant date fair value of such RSUs is equal to the closing price of our Common Stock on the grant date. The grant date fair value of performance-based vesting RSUs was determined using the Monte Carlo simulation model, which is based on a number of factors. The weighted average assumptions used in determining the grant date fair value of these awards are set forth in Note 2, “Summary of Significant Accounting Policies,” in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2021.

4. Reflects awards of time-based vesting RSUs under the 2014 Incentive Plan. Each award vests in three equal annual installments on March 1, 2022, 2023, and 2024.

5. Reflects awards of one-time sign-on time-based vesting RSUs under the 2014 Incentive Plan. Each award vests in three equal annual installments on March 1, 2022, 2023, and 2024. For more information regarding these awards, see the discussion in the “Compensation Discussion and Analysis” section above.

6. Mr. Crow retired as Chief Executive Officer on April 1, 2021 and was not granted any plan-based awards in 2021.

1. Reflects the value as calculated using the closing market price of our Common Stock as of December 31, 2021 ($85.71).

2. Restricted stock units awarded to the executive on March 15, 2021 under the 2014 Incentive Plan. The restricted stock units vest in three equal annual installments on each of March 15, 2022, 2023, and 2024. Each restricted stock unit converts into one share of common stock upon vesting.

Executive Compensation and Other Information

3. Restricted stock units awarded to the executive on March 15, 2021 under the 2014 Incentive Plan. The award vests on March 15, 2024 based on four separate performance measures: an annual return on invested capital (“ROIC”) measurement for each of 2021-2023 and a cumulative ROIC measurement for performance over that three-year period. For each of the annual tranches, (i) minimum payout requires achieving the actual ROIC performance for the prior year, (ii) full payout requires achieving the actual ROIC performance for the prior year plus a 12.5% improvement, and (iii) maximum payout requires achieving a 25% improvement over the actual ROIC performance for the prior year. When used as a target to calculate 2021 ROIC, actual ROIC for 2020 is calculated on a combined pro forma basis for the Corporation and BMC. For the three-year average tranche, (i) minimum payout requires achieving pro forma 2020 ROIC plus a 12.5% improvement, (ii) the full payout target is a 12.5% increase over that minimum target, and (iii) the maximum target is a 25% increase above the minimum payout threshold. Payout percentages between targets are linear. Additionally, the awards are subject to a total shareholder return (“TSR”) modifier. If the Corporation’s TSR is in the bottom two of a selected peer group, the payout based on the ROIC percentage will be reduced by 10%. If the Corporation’s TSR is in the top two of the selected peer group, the payout based on the ROIC percentage will be increased by 10%. The amounts reflected assume target payouts.

4. Restricted stock units awarded to the executive on October 31, 2017 under the 2014 Incentive Plan. One half of the award vests on March 1, 2022 if the Corporation’s earnings before adjustments for interest, taxes, depreciation, and amortization for the year ended December 31, 2021 (“2021 Adjusted EBITDA”) equals or exceeds $650 million. The other half of the award vests on March 1, 2022 if the Corporation’s ratio of net debt to 2021 Adjusted EBITDA on December 31, 2021 is equal to or less than 3.0:1. Each restricted stock unit converts into one share of common stock upon vesting. The performance period has been completed and the amount reflected is the actual amount earned.

5. Restricted stock units awarded to the executive on March 1, 2019 under the 2014 Incentive Plan. The restricted stock units vest in three equal annual installments on each of March 1, 2020, 2021, and 2022. Each restricted stock unit converts into one share of common stock upon vesting.

6. Restricted stock units awarded to the executive on March 1, 2019 under the 2014 Incentive Plan. The award vests on March 1, 2022 based on four separate performance measures: an annual return on invested capital (“ROIC”) measurement for each of 2019-2021 and a cumulative ROIC measurement for performance over that three-year period. For each of the annual tranches, (i) minimum payout requires achieving the actual ROIC performance for the prior year, (ii) full payout requires achieving the actual ROIC performance for the prior year plus a 7.5% improvement, and (iii) maximum payout requires achieving a 17.5% improvement over the actual ROIC performance for the prior year. When used as a target to calculate 2021 ROIC, actual ROIC for 2020 is calculated on a combined pro forma basis for the Corporation and BMC. For the three-year average tranche, (i) minimum payout requires achieving the average of the 2019-2021 ROIC minimum targets plus a 7.5% improvement, (ii) the full payout target is a 7.5% increase over that minimum target, and (iii) the maximum target is a 17.5% increase above the minimum payout threshold. Payout percentages between targets are linear. Additionally, the awards are subject to a TSR modifier. If the Corporation’s TSR is in the bottom two of a selected peer group, the payout based on the ROIC percentage will be reduced by 10%. If the Corporation’s TSR is in the top two of the selected peer group, the payout based on the ROIC percentage will be increased by 10%. The performance period has been completed and the amounts reflected are the actual amounts earned.

7. Restricted stock units awarded to Mr. Crow on April 10, 2020 and to Messrs. Jackson and Robins on March 1, 2020 under the 2014 Incentive Plan. The restricted stock units vest in three equal annual installments on each of March 1, 2021, 2022, and 2023. Each restricted stock unit converts into one share of common stock upon vesting.

8. Restricted stock units awarded to Mr. Crow on April 10, 2020 and to Messrs. Jackson and Robins on March 1, 2020 under the 2014 Incentive Plan. The award vests on March 1, 2023 based on four separate performance measures: an annual return on invested capital (“ROIC”) measurement for each of 2020-2022 and a cumulative ROIC measurement for performance over that three-year period. For each of the annual tranches, (i) minimum payout requires achieving the actual ROIC performance for the prior year, (ii) full payout requires achieving the actual ROIC performance for the prior year plus a 7.5% improvement, and (iii) maximum payout requires achieving a 17.5% improvement over the actual ROIC performance for the prior year. When used as a target to calculate 2021 ROIC, actual ROIC for 2020 is calculated on a combined pro forma basis for the Corporation and BMC. For the three-year average tranche, (i) minimum payout requires achieving the average of the 2020-2022 ROIC minimum targets plus a 7.5% improvement, (ii) the full payout target is a 7.5% increase over that minimum target, and (iii) the maximum target is a 17.5% increase above the minimum payout threshold. Payout percentages between targets are linear. Additionally, the awards are subject to a TSR modifier. If the Corporation’s TSR is in the bottom two of a selected peer group, the payout based on the ROIC percentage will be reduced by 10%. If the Corporation’s TSR is in the top two of the selected peer group, the payout based on the ROIC percentage will be increased by 10%. The amounts reflected assume maximum payouts excluding any TSR modifier.

9. Restricted stock units awarded to the executive on March 1, 2020 under the 2014 Incentive Plan. The restricted stock units vest in full on March 1, 2022. Each restricted stock unit converts into one share of common stock upon vesting.

10. Stock options assumed by the Company in connection with the Merger and converted into options to purchase the common stock of the Company.

11. Restricted stock units awarded to the executive on June 24, 2021 under the 2014 Incentive Plan. The restricted stock units vest in three equal annual installments on each of March 15, 2022, 2023, and 2024. Each restricted stock unit converts into one share of common stock upon vesting.

Potential Payments Upon Termination or Change in Control

As described above in “Employment Agreements,” we entered into employment agreements with our NEOs, which, among other things, provide benefits to them in the event of a termination of employment under certain circumstances. These agreements, as in effect for 2021, are described below.

Termination by the Corporation Without Cause; Certain Terminations by the Executive; Non-Renewal of Employment Agreement; Mutual Consent to Termination.  Under Mr. Flitman’s employment agreement and following the Merger Effective Date, in the event that (i) his employment is terminated by us without “cause” (as defined in the employment agreement), or (ii) he terminates his employment for “good reason” (as defined in the employment agreement, and which includes a “change in control”), he is entitled to (a) the sum of Mr. Flitman’s base salary and target bonus, payable in equal installments according to our normal payroll practices over the period of 12 months following the termination date and health benefit continuation for 12 months following the termination date if such date is on or before the Merger Effective Date, or (b) 1.5 times the sum of Mr. Flitman’s base salary and target bonus, payable in equal installments according to our normal payroll practices over the period of eighteen months following the termination date and health benefit continuation for eighteen months following the termination date if such date is after the Merger Effective Date.

Under each of the employment agreements for Messrs. Jackson, Robins, Farmer, and Johnson, in the event that (i) the executive’s employment is terminated by us without “cause” (as defined in the employment agreement), or (ii) the executive terminates his employment for “good reason” (as defined in the employment agreement, and which includes a “change in control”), the executive is entitled to (a) the sum of his base salary and target bonus, payable in equal installments according to our normal payroll practices over the period of 12 months following the termination date and (b) health benefit continuation for 12 months following the termination date. Under the employment agreements for each of Messrs. Jackson and Robins, in the event that he is terminated without cause or for good reason on or prior to June 30, 2022, all of executive’s unvested restricted stock units issued prior to December 15, 2020 shall accelerate and immediately vest.

Mr. Crow’s consulting agreement does not contain provisions related to termination without “cause” or for “good reason.”

Restrictive Covenants.  Mr. Flitman’s employment agreement contains customary restrictive covenants, including non-competition, non-interference, and non-solicitation covenants that apply during the period of his employment and for 18 months after his termination date. The employment agreement for our other NEOs and Mr. Crow’s consulting agreement also contain customary restrictive covenants, including non-competition, non-interference,

Executive Compensation and Other Information

and non-solicitation covenants that apply during the period of his employment and for 12 months after an executive’s termination date or the termination of Mr. Crow’s consulting period on April 1, 2023, respectively.

Death or Disability.  The employment agreements do not provide for any payments in such event.

Summary of Termination Payments and Benefits

The following table summarizes the value of the termination payments and benefits that our NEOs would receive if they had terminated employment on December 31, 2021 under the circumstances shown. The amounts shown in the table exclude distributions under our 401(k) retirement plan and any additional benefits that are generally available to all of our salaried employees. Mr. Crow’s consulting agreement may not be terminated before the end of the consulting period ending on April 1, 2023 and he is therefore not entitled to any termination payments or benefits.

1. This amount includes the dollar value of continuation of the executive’s then-current base salary for a period of 12 months and the payment of his target bonus in equal installments over 12 months for Messrs. Flitman, Jackson, Farmer, and Johnson. For Mr. Robins, this amount only includes the dollar value of continuation of his then-current base salary for 12 months.

2. The dollar value represents the cost of providing continued health and welfare benefits to the executive for one year after his date of termination of employment.

3. Amount reflects the acceleration of all outstanding and unvested time-based and performance-based RSUs at target payouts granted to executive prior to December 15, 2020, held by executive on December 31, 2021, and multiplied by the closing market price of our Common Stock on that date ($85.71).

4. Payments of cash severance under these agreements will be made in accordance with the Corporation’s regular payroll practices. However, to the extent any amount or benefit would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Internal Revenue Code of 1986, as amended, (i) the payment of such amount or benefit shall only be in connection with an event that constitutes a Section 409A-compliant “separation from service” and (ii) if the amount or benefit would otherwise be payable or distributable during a period in which the executive is a “specified employee” (as defined in Code Section 409A and the final regulations thereunder), then the executive’s right to receive such payment or distribution will be delayed until the earlier of the executive’s death or the first day of the seventh month following the executive’s separation of service.

5. Amount reflects the acceleration of all outstanding and unvested time-based and performance-based RSUs at target payouts held by executive on December 31, 2021 and multiplied by the closing market price of our Common Stock on that date ($85.71).

6. Amount reflects the acceleration of all outstanding and unvested time-based RSUs held by executive on December 31, 2021 and multiplied by the closing market price of our Common Stock on that date ($85.71).

Executive Compensation and Other Information

Chief Executive Officer Pay Ratio Disclosure

Below is: (i) the 2021 annual total compensation of our CEO; (ii) the 2021 annual total compensation of our median employee; (iii) the ratio of the annual total compensation of our CEO to that of our median employee; and (iv) the methodology we used to calculate our CEO pay ratio:

CEO Pay Ratio
CEO Annual Total Compensation	$	10,138,201
Median Employee Annual Total Compensation	$	61,301
Median Employee Pay Ratio		165:1

To determine our median employee’s pay, we chose total cash compensation paid through our payroll system in 2021 as our consistently applied compensation measure. That amount does not include any 401(k) match. We then annualized base salary for those employees who commenced work during 2021 and any employees who were on an unpaid leave of absence for a portion of 2021. As of December 31, 2021, we had 27,834 employees. Using this methodology, we identified the median employee as of December 31, 2021.

That median employee’s total annual compensation in 2021 includes total cash compensation paid through our payroll system in 2021, the value of company-paid cost of health and life insurance, and the value of company-paid contributions to the employee’s 401(k) plan, if any. Because Mr. Flitman was elected President of the Company on January 1, 2021 and the terms of his compensation did not change when he became CEO on April 1, 2021, Mr. Flitman’s total annual compensation includes his base salary, long-term equity incentives awards, non-equity incentive plan bonus, company-paid contributions to his 401(k) plan, and the value of company-paid cost of health and life insurance. The value of company-paid health and life insurance is not included for Mr. Flitman in the Summary Compensation Table above because that benefit is available to all full-time employees and does not discriminate against lower-paid employees.

Given the different methodologies that various public companies will use to determine an estimate of their pay ratio, the estimated ratio reported above should not be used as a basis for comparison between companies.

Proposal 2 — Advisory Vote on Executive Compensation

PROPOSAL 2 — ADVISORY VOTE ON EXECUTIVE COMPENSATION

As required by Section 14A of the Securities Exchange Act, this proposal provides stockholders with an opportunity to cast a non-binding, advisory vote on the 2021 compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the disclosure rules of the Securities and Exchange Commission. This proposal, commonly known as a “say on pay” proposal, gives stockholders the opportunity to approve, reject, or abstain from voting with respect to our fiscal 2021 executive compensation program.

At the 2021 annual meeting of stockholders, over 95% of the shares represented at the meeting in person or by proxy and entitled to vote were voted in support of the Corporation’s compensation program. At the 2017 annual meeting of stockholders, the Corporation’s stockholders selected, on a non-binding, advisory basis, an annual vote for the frequency at which the Corporation should include a say on pay vote in its proxy statement for stockholder consideration. In light of this result and other factors considered by the Board, the Board determined that the Corporation will hold say on pay votes every year until the next required non-binding, advisory vote on the frequency of such votes, which is required to be held no later than the Corporation’s 2023 annual meeting of stockholders.

As discussed in the “Compensation Discussion and Analysis” section of this Proxy Statement, our 2021 executive compensation program has been designed to provide a total compensation package that allows us to attract, retain, and motivate executives who have the talent to capably manage our business.

Our compensation program is intended to:

• Provide total compensation opportunities at levels that are competitive for comparable positions at companies with whom we compete for talent,

• Provide incentives to our executive officers to achieve key financial objectives set by the Board,

• Provide an appropriate mix of fixed and variable pay components to establish a “pay-for-performance” oriented compensation program,

• Align the financial interests of executives with stockholder interests by providing significant compensation opportunities in the form of equity awards, and

• Emphasize direct pay components such as cash and equity and avoid indirect compensation such as benefits and perquisites that are not available to employees generally.

This proposal allows our stockholders to express their opinions regarding the decisions of the Board and the Compensation Committee on the annual compensation for the NEOs in 2021. This advisory vote will serve as an additional tool to guide the Board and the Compensation Committee in evaluating the alignment of the Corporation’s executive compensation program with the interests of the Corporation and its stockholders. Approval of this proposal requires the affirmative vote of the holders of a majority of the shares represented and entitled to vote on this proposal at the annual meeting.

Because the vote on this proposal is advisory in nature, it will not affect any compensation already paid or awarded to any NEO and will not be binding on or overrule any decisions by the Board. The Compensation Committee and the Board will consider the outcome of the vote when setting future compensation arrangements for our NEOs.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” APPROVAL OF THE 2021 EXECUTIVE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT.

Certain Relationships and Related Party Transactions

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

The Corporation’s Code of Business Conduct and Ethics and its Supplemental Code of Ethics, both of which are in writing, provide guidelines for identifying, reviewing, approving, and ratifying related party transactions. Related party transactions include those transactions that create an actual, apparent, or potential conflict of interest. Related party transactions involving the Corporation’s Chief Executive Officer, President, Chief Financial Officer, or Controller (or persons forming similar functions, including our Chief Accounting Officer) must be submitted to the General Counsel for review. If the General Counsel determines that an actual or apparent conflict of interest exists, the transaction must be submitted to the Audit Committee for approval. The directors and executive officers, as well as all other employees of the Corporation, must obtain a waiver for any activity that violates the Corporation’s Code of Business Conduct and Ethics. The Corporation’s Compliance Committee, which is made up of representatives from our Finance, Legal, Human Resources, and Internal Audit Departments, is responsible for the administration of the Code of Business Conduct and Ethics. However, only the Audit Committee may waive any violation of this code by directors or executive officers.

Additionally, the Corporation has adopted a Related Party Transaction Policy that sets forth the process by which the Audit Committee will review certain related party transactions between the Corporation and its executive officers, directors, and greater than five percent beneficial owners, and their immediate family members, and the Corporation.

The Corporation’s By-laws provide that no contract or transaction between the Corporation and one or more of its directors or officers, or between the Corporation and any other entity in which one or more of its directors or officers are directors or officers or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board or committee thereof that authorizes the contract or transaction, or solely because any such director’s or officer’s vote is counted for such purpose, if: (i) the material facts as to the director’s or officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the Board or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum, (ii) the material facts as to the director’s or officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders, or (iii) the contract or transaction is fair as to the Corporation as of the time it is authorized, approved, or ratified by the Board, a committee thereof, or the stockholders.

Certain members of the Corporation’s Board of Directors serve on the board of directors for one of our suppliers, PGT Innovations, Inc. The Corporation purchases building materials from PGT Innovations, Inc. in the ordinary course of business and on terms no less favorable to us than we could obtain from unaffiliated third parties. We anticipate that such purchases will continue in the foreseeable future. In addition, as of January 1, 2021, a member of the Board is an executive officer of one of our customers, Ashton Woods USA, L.L.C. Sales to Ashton Woods USA. L.L.C. made up approximately 1% of our net sales in 2021.

Ownership of our Common Stock is shown in terms of “beneficial ownership.” Amounts and percentages of Common Stock beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which he or she has a right to acquire beneficial ownership within 60 days. More than one person may be considered to beneficially own the same shares. In the table below, unless otherwise noted, a person has sole voting and dispositive power for those shares shown as beneficially owned by such person.

Total		2,256,476		$      9.60(2)		7,969,483

1. Includes (i) 174,243 shares to be issued upon exercise of options granted under the Builders FirstSource, Inc. 2005 Equity Incentive Plan, the Builders FirstSource, Inc. 2007 Incentive Plan, and the Builders FirstSource, Inc. 2014 Incentive Plan and (ii) 2,063,383 shares to be issued upon the full vesting of restricted stock units granted under the 2014 Incentive Plan. The 2005 Equity Incentive Plan was approved by the Corporation’s stockholders in June 2005. The Corporation’s stockholders approved the 2007 Incentive Plan in May 2007 and reapproved the plan in January 2010. The 2014 Incentive Plan was approved by the Corporation’s stockholders in May 2014 and reapproved by the Corporation’s stockholders in May 2016. The Stock Building Supply Holdings, Inc. 2013 Incentive Compensation Plan (the “BMC 2013 Plan”) was assumed by the 2014 Incentive Plan on January 4, 2021 pursuant to the Registration Statement on Form S-8 filed by the Company with the SEC on such date. The 2005 Equity Incentive Plan expired in June 2015, and the 2007 Incentive Plan expired in May 2017, but such expirations will not adversely affect any awards issued under either plan prior to its expiration. It is assumed that the maximum number of shares will be issued on payout for RSUs that contain variable payout provisions. If it is assumed that shares will be issued at the target vesting amount for outstanding RSUs with variable payout provisions, an additional 844,864 shares would be included in the shares available for future issuance under the 2014 Incentive Plan.

2. Restricted stock units are excluded from the calculation of weighted average exercise price.

3. Securities available for future awards pursuant to the 2014 Incentive Plan, which was approved by the Corporation’s stockholders in May 2014 and reapproved in May 2016, including the shares assumed under the BMC 2013 Plan. Under our 2014 Incentive Plan, the Corporation is authorized to grant awards in the form of incentive stock options, non-qualified stock options, restricted stock shares, restricted stock units, other common stock-based awards, and cash-based awards. The maximum number of shares of Common Stock initially reserved for awards (including future grants, currently outstanding awards, and previously exercised awards) under the 2014 Incentive Plan (including the BMC 2013 Plan) as of December 31, 2021 was 15,152,523, subject to adjustment as provided by the plan. All 15,152,523 shares under the 2014 Incentive Plan may be made subject to options, SARs, or stock-based awards. The 6,652,523 shares assumed under the BMC 2013 Plan may only be issued to participants who were not Builders FirstSource employees on the Merger Effective Date.

4. Includes securities to be issued upon exercise of options under the Builders FirstSource, Inc. 1998 Stock Incentive Plan, as amended. No grants were made under this plan after the Corporation’s initial public offering in June 2005. No further grants will be made under this plan.

Proposal 3 — Ratification of Selection of Independent Registered Public Accounting Firm

PROPOSAL 3 — RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Based upon the recommendation of the Audit Committee, the Board of Directors selected PricewaterhouseCoopers LLP (“PwC”) to serve as the Corporation’s independent registered public accounting firm (the “auditors”) for the year ending December 31, 2022. As a matter of good corporate governance, the stockholders will be requested to ratify the Audit Committee’s selection at the annual meeting. Representatives of PwC will be present at the annual meeting, have the opportunity to make a statement if they desire to do so, and be available to answer appropriate questions.

If the stockholders do not ratify the appointment of PwC, the selection of auditors will be reconsidered by the Audit Committee. Even if the appointment is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm, subject to ratification by the Board, at any time during the year if it determines that such a change would be in the best interests of the Corporation and its stockholders.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

Fees Paid to PricewaterhouseCoopers LLP

The following table shows the fees paid or accrued by the Corporation for the audit and other services provided by PwC for fiscal years 2021 and 2020.

	2021		2020
Audit fees(1)		$5,840,000		$3,615,000
Audit-related fees(2)		754,150		671,210
Tax fees(3)		547,180		308,101
All other fees(4)		—		15,000
Total PwC fees		$7,141,330		$4,609,311

1. Audit fees of PwC for 2021 and 2020 consisted of the audit and quarterly reviews of the consolidated financial statements of the Corporation, the audit of the effectiveness of management’s internal control over financial reporting, the review of filings made with the SEC, preparation of comfort letters, and work on registration statements.

2. Audit-related fees of PwC for 2021 and 2020 include assistance with due diligence in connection with the Corporation’s acquisition of BMC and other acquisitions and transactions.

3. Tax fees for 2021 and 2020 include assistance with the preparation of tax returns of certain of the Corporation’s subsidiaries and assistance with audits, as well as tax planning and advising management as to the tax implications of certain transactions undertaken by the Corporation.

4. All other fees in 2020 relate to certain other advisory services provided to the Corporation by PwC.

The Audit Committee determined that the provision of services related to audit services, audit-related services, tax compliance, advisory services, and other services is compatible with maintaining the independence of PwC. PwC did not render professional services relating to financial information systems design and implementation for the fiscal years ended December 31, 2020 or 2021.

The Audit Committee has the sole and direct authority to engage, appoint, and replace our auditors. In addition, the Audit Committee has established in its charter a policy that every engagement of PwC to perform audit or permissible non-audit services on behalf of the Corporation or any of its subsidiaries requires pre-approval from the Audit Committee or its designee before PwC is engaged to provide those services. Pursuant to the Audit Committee Charter, the Audit Committee reviews and, in its sole discretion, approves in advance the Corporation’s auditors’ annual engagement letter, including the proposed fees contained therein, as well as all audit and, as provided in the Sarbanes-Oxley Act of 2002 and the SEC rules and regulations promulgated thereunder, all permitted non-audit engagements and relationships between the Corporation and such auditors

Builders FirstSource, Inc.  |  2022 Proxy Statement    59

Proposal 3 — Ratification of Selection of Independent Registered Public Accounting Firm

(which approval should be made after receiving input from the Corporation’s management, if desired). Approval of audit and permitted non-audit services will be made by the Audit Committee as set forth in the Audit and Non-Audit Services Pre-Approval Policy (the “Pre-Approval Policy”). Under the Pre-Approval Policy, the Audit Committee may delegate either specific or general pre-approval authority to one or more of its members. The Pre-Approval Policy delegates specific pre-approval authority to its chair for services subject to the policy, provided that the estimated fees for any such proposed pre-approved services do not exceed $500,000 in the aggregate and the services are not specifically prohibited by the Pre-Approval Policy. The Chair of the Audit Committee must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

Under the Pre-Approval Policy, the Audit Committee must specifically pre-approve a service unless the type of service has received general pre-approval. The Audit Committee annually reviews and generally pre-approves the services that may be provided by the independent auditor during the following calendar year without obtaining specific pre-approval from the Audit Committee. The Corporation’s Chief Financial Officer, in consultation with the Chair of the Audit Committee, will determine whether services are eligible for general pre-approval. The Pre-Approval Policy sets out certain audit, audit-related, and tax services that have the general pre-approval of the Audit Committee for an amount not to exceed $500,000. The Audit Committee may specifically pre-approve any services in these categories that exceed the permitted general pre-approval amount.

As a result, the Audit Committee or its designee approved 100% of all services performed by PwC on behalf of the Corporation and its subsidiaries in 2021.

Proposal 4 — Adopt Greenhouse Gas Emissions Reduction Targets

PROPOSAL 4 — ADOPT GREENHOUSE GAS EMISSIONS REDUCTION TARGETS

The following stockholder proposal has been submitted to the Corporation for action at the annual meeting by Green Century Capital Management, Inc., 114 State Street, Suite 200, Boston, Massachusetts 02109. The proposal will be voted on at the annual meeting only if properly presented by or on behalf of the proponent. In accordance with applicable proxy regulations, the proposal and supporting statement, for which we accept no responsibility, are set forth below exactly as they were submitted by the proponent.

Whereas: In 2018, the Intergovernmental Panel on Climate Change advised that greenhouse gas emissions must be reduced 45% by 2030 and reach net zero by 2050 to limit warming to 1.5° Celsius, prevent the worst consequences of climate change, and meet the goals of the Paris Agreement. The UN reports that the world is “way off track” in its efforts to achieve these targets, spurring investors to seek corporate commitments to science-based greenhouse gas emissions (GHG) reduction goals.

Companies, such as Builders FirstSource (BFS), that provide construction services and forestry products are vulnerable to the physical, operational, and supply chain risks caused by climate change. With predicted increases in the severity of hurricanes, heat waves, wildfires and long-lasting droughts, BFS’ wood product supply may be disrupted, and its facilities, vehicles, and equipment may be damaged or destroyed. In its 2020 10-k, BFS acknowledges that climate change could “reduce or delay construction activity, which could adversely impact our financial condition, operating results and cash flows”.

Wood products contribute significantly to deforestation and forest degradation, which are responsible for approximately 12.5 percent of global greenhouse gas emissions. In 2020, BFS derived nearly 36% of its net sales from selling lumber and lumber sheet goods, but the Company has yet to account for emissions linked to the harvesting and manufacturing of wood products or for any other emissions from its operations or value chain. Further, BFS has neither greenhouse gas emissions reduction targets nor time-bound commitments to set targets for reducing its Scope 1, 2, and 3 emissions.

Given the current and predicted impacts of climate change and the resulting threats to BFS’ financial health, and more broadly, to natural systems and the global economy, proponents believe that the Builders FirstSource board and management have a responsibility to their investors and stakeholders to mitigate climate-related risks by committing to and adopting science-based greenhouse gas goals that cover Scope 1, 2 and 3 emissions and that align with a 1.5° Celsius scenario.

Resolved: Shareholders request that Builders FirstSource adopt short, medium, and long-term science-based greenhouse gas emissions reduction targets, inclusive of emissions from its full value chain, in order to achieve net-zero emissions by 2050 or sooner and to effectuate appropriate emissions reductions prior to 2030.

Supporting Statement: In assessing targets, proponents recommend, at management’s discretion:

• Consideration of approaches used by advisory groups such as the Science Based Targets initiative;

• Adopting emissions reduction targets inclusive of all GHG Protocol-defined sources of Scope 3 emissions—including from deforestation and forest degradation—that align with limiting temperature increases to 1.5° Celsius;

• Within the Company’s operations, setting goals for renewable energy sourcing, energy efficiency improvements, and transitioning to zero emissions vehicles.

Builders FirstSource Sustainability Strategy

We are actively engaged in implementing our own sustainability strategy that substantially complies with this stockholder proposal, which we outline below. While the Board does not believe the stockholder proposal benefits the Company, the Board is not making a recommendation with respect to the stockholder proposal because (i) the Company already has plans to substantially comply with the goals of the proposal and (ii) the disclosures and timeline that would be required to comply with the proposal are overly burdensome for the Company in light of the recent Merger.

Builders FirstSource, Inc.  |  2022 Proxy Statement    61

Proposal 4 — Adopt Greenhouse Gas Emissions Reduction Targets

We are committed to long-term greenhouse gas emission reductions, forest protection and continuing our efforts to build a more sustainable company. Following the Merger in early 2021, we have made considerable strides integrating BMC’s products, operations and people in order to efficiently and effectively maximize the benefits of the Merger. As part of these efforts, we integrated BMC’s environmental, social and governance practices with our own existing policies and programs.

Historically, our core sustainability efforts have focused on responsibly sourcing our products and reducing our use of traditional, non-renewable energy sources. As part of our sourcing initiatives, we prioritize sourcing Sustainable Forestry Initiative (“SFI”) certified wood. Approximately 90% of the wood we purchased in 2021 was certified sustainable by SFI. In addition, we have also taken steps to improve renewable energy sourcing and energy efficiency and reduce vehicle emissions. These efforts include the use of renewable energy, LED lighting and fans at many of our facilities in order to reduce our reliance on traditional energy sources, maximizing fleet efficiency through DDMS delivery routing systems, and the use of electric forklifts.

Currently, our focus is on continuing to expand our existing sustainability efforts in addition to improving our sustainability reporting and disclosures.

In 2021, we published information regarding our sustainability efforts, which is available on our website at investors.bldr.com/ESG.

Moreover, our executive leadership continues to emphasize the importance of these goals and has publicly committed to publishing our first Corporate Social Responsibility Report (the “CSR Report”) prior to the 2022 Annual Meeting. The CSR Report will disclose environmental sustainability metrics that are material to

the Company and its business using the framework developed by the Task Force on Climate-Related Financial Disclosures and the Building Products and Furnishings standards set forth by the Sustainability Accounting Standards Board.

Additionally, we are working towards a comprehensive plan to reduce our greenhouse gas emissions. As part of our comprehensive plan to reduce our greenhouse gas emissions, we are committed to taking the following steps:

• Quantifying and disclosing our Scope 1 and 2 greenhouse gas emissions in 2023. We are actively engaging in efforts to quantify and disclose Scope 3 greenhouse gas emissions in the near term.

• Assessing setting a net-zero science-based target with the Science Based Targets initiative (“SBTi”). As per the SBTi rules, after committing to set a science-based target, the Company would have two years to develop, submit, and set a target through SBTi.

• Integrating zero emission vehicles into our fleets, and we expect that our operations will become increasingly energy efficient, especially with respect to Scope 1 emissions.

• Prioritize sourcing wood from SFI or FSC certified vendors, particularly for wood from Canadian boreal forests and temperate rainforests.

We are strongly committed to meeting the challenges of reducing our greenhouse gas emissions and look forward to continuing our sustainability efforts, and communicating these efforts to shareholders, in the months and years ahead. We will continue to engage with our shareholders to solicit their perspectives on our sustainability efforts, and appropriately integrate the feedback provided by our shareholders as our policies, practices, and disclosures evolve.

FOR THE REASONS OUTLINED ABOVE, THE BOARD OF DIRECTORS DOES NOT MAKE A RECOMMENDATION WITH RESPECT TO THE STOCKHOLDER PROPOSAL.
