In accordance with the rules of the Securities and Exchange Commission (the "SEC"), we sent a Notice of Internet Availability of Proxy Materials on or about March 29, 2023, to our Shareholders of record as of the close of business on March 20, 2023. We also provided access to our proxy materials over the Internet beginning on that date.

## Record Date; Proxies; Voting

WHO CAN VOTE; VOTES PER SHARE

The Board has set March 20, 2023, as the record date for the Annual Meeting. At the Annual Meeting, each Shareholder of record of Common Shares at the close of business on the record date will be entitled to vote on all matters proposed to come before the Annual Meeting. Each such Shareholder of record will be entitled to one vote per Common Share on each matter submitted to a vote of Shareholders, as long as those shares are represented at the Annual Meeting, either in person or by proxy.

The Company is authorized to issue an unlimited number of Common Shares and an unlimited number of special shares (the "Special Shares"). As of March 20, 2023, there were 22,217,287 Common Shares and no Special Shares outstanding.

HOW TO VOTE

You may vote your shares by attending the Annual Meeting via the Internet at https://web.lumiagm.com/213788577 or in person. For Shareholders who attend the Annual Meeting via the Internet and wish to vote their shares online during the Annual Meeting, see below under "How to Attend the Annual Meeting" for additional details.

In addition, in advance of the Annual Meeting, registered Shareholders may submit their vote by proxy through the Internet by going to www.voteproxy.com and entering their control number on their Notice of Internet Availability of Proxy Materials or proxy card. Registered Shareholders may also vote by proxy:

• using the telephone number listed on their proxy card; or

• signing, completing and returning the proxy card in the postage paid envelope provided.

When you cast your vote by proxy, you are legally authorizing another person to vote your shares. The persons specified on the enclosed proxy card are officers of the Company. A registered Shareholder who wishes to appoint any person other than those specified on the enclosed proxy card to represent that Shareholder at the Annual Meeting may do so by crossing out the persons named in the enclosed proxy card and inserting such other person's name in the blank space provided in the proxy card or by completing another proper proxy. Such other person need not be a Shareholder. Please note that if you appoint as proxy any person other than those specified by the Company on your form of proxy and neither you nor your proxy attends the Annual Meeting in person, then your shares will not be voted.

If your shares are not registered in your name but in the "street name" of a bank, broker or other holder of record (a "nominee"), then your name will not appear in the Company's register of Shareholders, and you are considered a "Beneficial Holder". Those shares are held in your nominee's name, on your behalf, and your nominee will be entitled to vote your shares, provided, in most cases, that you provide your voting instructions to your nominee. If your shares are held in street name, please refer to the information from your bank, broker or other nominee on how to provide your voting instructions, which includes the applicable deadlines. Beneficial Holders may only vote shares held in street name at the Annual Meeting if they obtain a legal proxy from the registered holder (bank, broker or other nominee) giving the Beneficial Holder the right to vote the shares and bring it to the Annual Meeting.

To be valid, forms of proxy submitted by registered holders must be deposited at the offices of American Stock Transfer & Trust Company, LLC (the "Agent"), at 6201 15th Avenue, Brooklyn, New York 11219, so as not to arrive later than 9:00 a.m. (Eastern Time) on May 10, 2023, or be provided, at the Annual Meeting, to the chair of the Annual Meeting (the "Chair of the Meeting"). If the Annual Meeting is adjourned, forms of proxy must be deposited to the Agent within 48 hours (excluding Saturdays, Sundays and holidays) before the time set for any reconvened meeting at which the forms of proxy are to be used, or be provided, at the Annual Meeting, to the Chair of the Meeting or any reconvened meeting.

The document appointing a proxy must be in writing and completed and signed by a Shareholder or his or her attorney authorized in writing or, if the Shareholder is a corporation, under its corporate seal or by an officer or

attorney thereof duly authorized.

HOW YOUR PROXY WILL BE VOTED; DISCRETIONARY AUTHORITY OF PROXIES

HOW YOUR PROXY WILL BE VOTED; DISCRETIONARY AUTHORITY OF PROXIES

The persons named in the accompanying proxy will vote the Common Shares in respect of which they are appointed, on any ballot that may be called for, in accordance with the instructions of the Shareholder as indicated in the form of proxy. If a Shareholder signs and returns a proxy card, but does not give voting instructions, the shares represented by that proxy will be voted as recommended by the Board, as follows:

• **Proposal 1:** FOR the election of Howard C. Heckes, Jody L. Bilney, Robert J. Byrne, Peter R. Dachowski, Jonathan F. Foster, Daphne E. Jones, Barry A. Ruffalo, Francis M. Scricco, and Jay I. Steinfeld to the Board to fill these positions as described under the heading "Election of Directors."

• **Proposal 2:** FOR the approval, on an advisory basis, of the executive compensation paid by the Company to its named executive officers included in this Proxy Statement as described under the heading "Advisory Vote on Executive Compensation."

• **Proposal 3:** FOR the appointment of Ernst & Young LLP, an independent registered public accounting firm, to serve until the next annual general meeting of Shareholders and to authorize the Board to fix the auditor's remuneration as described under the heading "Appointment of Independent Registered Accounting Firm."

If any other matters are properly brought before the Annual Meeting (other than the proposals contained in the Notice of Annual Meeting and this Proxy Statement), then the named proxies will have the authority to vote your shares on those matters in accordance with their discretion and judgment. The Board currently does not know of any matters to be raised at the Annual Meeting other than the proposals contained in the Notice of Annual Meeting and Proxy Statement. If a Shareholder votes via the Internet or by telephone, his, her or its electronic vote authorizes the named proxies in the same manner as if the Shareholder signed, dated and returned a proxy card by mail.

QUORUM; VOTES NECESSARY TO PASS RESOLUTIONS

Pursuant to the Articles of the Company, a quorum for the transaction of business at the Annual Meeting is at least three persons who are, or who represent by proxy, unrelated Shareholders, holding in the aggregate at least 15% of the Common Shares entitled to be voted at the Annual Meeting. For purposes of determining a quorum, abstentions and broker "non-votes" present in person or by proxy are counted as represented. A broker "non-vote" occurs when a nominee (such as a broker) holding shares for a beneficial owner abstains from voting on a particular proposal because the nominee does not have discretionary voting power for that proposal and has not received instructions from the beneficial owner on how to vote those shares. Under current New York Stock Exchange ("NYSE") rules, your broker will not have discretion to vote your uninstructed shares with respect to Proposals 1 and 2. Your broker will have discretion to vote your uninstructed shares on Proposal 3 (appointment of Ernst & Young LLP as the auditors of the Company to serve until the next annual general meeting of Shareholders and Board authorization to fix the remuneration of the auditors).

The matters being considered and voted on at the Annual Meeting are subject to differing standards for approval as follows:

• **Proposal No. 1** is the election of directors. Each Shareholder may, in respect of each Common Share held, cast one vote with respect to each vacancy on the Board. There is no cumulative voting for the election of directors. Each Shareholder should indicate its decision in respect of each director nominee by voting "FOR" the nominee or "WITHHOLD" for the nominee. Those director nominees receiving the most votes will be elected as directors until all vacancies are filled. If the number of nominees for election is equal to the number of vacancies to be filled, then all such nominees will be declared elected by acclamation. Notwithstanding the foregoing, our Corporate Governance Guidelines provide that in an uncontested election, any nominee for director who receives a greater number of votes "withheld" from his or her election than votes "for" such election is required to tender his or her resignation following certification of the Shareholder vote.

• **Proposal No. 2** (advisory vote on executive compensation) is an ordinary resolution of the Shareholders, and will be considered approved upon an affirmative vote of a majority (in excess of 50%) of the votes cast on the matter by Shareholders at the Annual Meeting represented in person or by proxy. Notwithstanding the approval or non-approval of these resolutions, it is advisory in nature and is non-binding.

QUORUM; VOTES NECESSARY TO PASS RESOLUTIONS

• **Proposal No. 3:** (appointment of Ernst & Young LLP as the auditors of the Company to serve until the next annual general meeting of Shareholders and Board authorization to fix its remuneration) is an appointment. Each Shareholder may cast a vote "FOR" or "WITHHOLD" for Ernst & Young LLP as auditor, and their appointment is dependent on no other independent registered public accounting firm being put forward at the Annual Meeting and receiving more "FOR" votes than them.

Abstentions and broker "non-votes" will not be counted as votes cast and will not affect the voting results for any of the above noted matters.

SOLICITATION OF PROXIES; TABULATION OF VOTES

The Company will bear the cost of soliciting proxies on its behalf. Our directors, officers and employees may solicit proxies in person or by telephone, electronic transmission and facsimile transmission. We will not be specially compensating our directors, officers and employees for those services, but they may be reimbursed for their out-of-pocket expenses incurred in connection with the solicitation. We will also reimburse brokers, fiduciaries and custodians for their costs in forwarding proxy materials to beneficial owners of our Common Shares. American Stock Transfer & Trust Company, LLC will act as our Scrutineer at the Annual Meeting and assist us in tabulating the votes.

MASONITE 2023 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5

## Proposal 1: Election of Directors

------

The Sustainability and Governance Committee has recommended nine director nominees named below for election as directors at the Annual Meeting. All of the nominees named below are members of the current Board of the Company. Each director nominee has consented to being named in this Proxy Statement and to serve if elected for a one-year term.

William S. Oesterle will be retiring from the Board at the end of this current term and is not standing for re-election. The Board would like to acknowledge Mr. Oesterle for his outstanding service on our Board over the last five years. The size of the Board is being reduced from ten to nine members effective immediately prior to the election of the directors at the Annual Meeting. Assuming the election of each director nominee, our Board will consist of nine members, eight of whom are independent.

The nominees for director receiving a plurality of the votes cast at the Annual Meeting will be elected as a director. Notwithstanding the foregoing, our Corporate Governance Guidelines set forth our procedures if a director is elected to the Board in an uncontested election but receives a majority of "withheld" votes. In an uncontested election, any nominee for director who receives a greater number of votes "withheld" from his or her election than votes "for" such election is required to tender his or her resignation following certification of the Shareholder vote. The Sustainability and Governance Committee is required to consider all relevant factors and make recommendations to the Board with respect to any such letter of resignation. The Board is required to take action with respect to this recommendation within 90 days after the certification of the election results.

Each nominee elected as a director will continue in office until the 2024 annual general meeting of Shareholders and until his or her successor has been duly elected and qualified or until his or her earlier resignation or removal. We do not expect any of the nominees will be unable to stand for election or be unable to serve if elected. If any nominee becomes unable to serve or withdraws his or her name as a nominee, proxies may be voted for the election of such other person as the Board may designate or the number of directors may be reduced accordingly.

Diverse Skills, Experiences and Qualifications

The skills matrix below identifies our director nominees' prominent experiences and qualifications by name. Each director nominee brings his or her own unique background and range of expertise, knowledge and experience which provides an appropriate and diverse mix of qualifications necessary for our Board to effectively fulfill its oversight responsibilities. By its nature, the information contained in this matrix is not intended to be exhaustive, however, it aims to convey the general breadth of experience and qualifications that our director nominees bring to their work on the Masonite Board of Directors.

DIRECTOR QUALIFICATIONS

DIRECTOR QUALIFICATIONS

The Board seeks to ensure that it is composed of members whose particular experience, qualifications, attributes and skills, when taken together, will allow the Board to satisfy its oversight responsibilities effectively. Consistent with the Company's Sustainability and Governance Committee charter, in identifying candidates for membership on the Board, the Sustainability and Governance Committee takes into account all factors it considers appropriate, which may include strength of character, mature judgment, career specialization, relevant technical skills, diversity and the extent to which the candidate would fill a present need on the Board. We believe that the backgrounds and qualifications of our directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow our Board to fulfill its responsibilities. Consistent with its charter, the Sustainability and Governance Committee considers diversity of experience as well as diversity in gender and whether an individual represents an underrepresented minority or class as factors it considers in conducting its assessment of director nominees, along with such other factors as it deems appropriate given the then current needs of the Board and the Company, to maintain a balance of knowledge, experience, and capability.

When determining whether our director nominees have the experience, qualifications, attributes and skills, taken as a whole, to enable our Board to satisfy its oversight responsibilities effectively in light of our business and structure, our Board considers primarily on our longer-tenured directors' contributions to our success in recent years, the specific expertise that the more recently elected directors have and are expected to continue to contribute, and on the information discussed in the biographies set forth under "Election of Directors-Biographies."

PROCESS FOR SHAREHOLDERS TO RECOMMEND DIRECTOR NOMINEES

Pursuant to its charter, the Sustainability and Governance Committee will evaluate candidates for nomination to the Board, including those recommended by Shareholders, on a substantially similar basis as it considers other nominees, as described above. Shareholders wishing to propose a candidate for consideration may do so by submitting the proposed candidate's name, age, business address and residential address, principal occupation or employment, and certain other information required by our Articles, to the attention of our Corporate Secretary in accordance with our Articles and the Business Corporations Act (British Columbia) ("BCBCA").

BOARD STRUCTURE AND DIRECTOR INDEPENDENCE

Our business, property and affairs are managed under the direction of our Board, which currently has ten directors. and which will consist of nine directors following our 2023 Annual Meeting. Our Board has determined, after considering all the relevant facts and circumstances, that all of the directors other than Mr. Heckes, our President and Chief Executive Officer, are independent, as "independence" is defined by the listing standards of the NYSE, because they have no direct or indirect material relationship with the Company (either directly or as a partner, Shareholder or officer of an organization that has a relationship with us) that would cause the independence requirements of the NYSE listing standards to not be satisfied, and otherwise meet the NYSE listing standards. Members of our Board are kept informed of our business through discussions with our Chief Executive Officer, Chief Financial Officer and other officers, by reviewing materials provided to them, by visiting our offices and facilities, and by participating in meetings of the Board and its committees. We currently separate the roles of Chief Executive Officer and Chairman of the Board. This structure properly reflects our belief that our Shareholders' interests are best served by the day-to-day management direction of the Company under Mr. Heckes, as President and Chief Executive Officer, together with the leadership of our Chairman of the Board, Mr. Byrne.

MEETINGS OF THE BOARD

In 2022, there were seven meetings of the Board, 20 meetings of its key committees and 4 meetings of a special ad hoc subcommittee. All incumbent directors attended approximately ninety-seven percent (97%) or more of the meetings of the Board and of the committees on which they served during the portion of the year that they served as directors. Absent extraordinary circumstances, we expect all directors and nominees to attend our Annual Meeting. All directors who were nominated as directors for election in 2022 were in attendance at the 2022 annual general meeting of Shareholders.

EXECUTIVE SESSIONS

As required by the NYSE listing standards, non-employee directors meet by themselves, without management or employee-directors present, at regularly scheduled in-person Board meetings, meetings of the committees of the Board and videoconference meetings, as appropriate. The Chairman of the Board, Mr. Byrne, or the Chair of the committee, as applicable, presides at these meetings.

BOARD COMMITTEES; MEMBERSHIP

We currently have the following committees: Audit Committee, Human Resources and Compensation Committee, and Sustainability and Governance Committee, each of which has the responsibilities and composition described below. The Board has adopted charters for each of these committees describing the authority and responsibilities delegated to each committee by the Board. All committee charters are available at our website, www.masonite.com, and available in print to any Shareholder without charge, upon request to Masonite International Corporation, 1242 East 5th Avenue, Tampa, FL 33605 Attention: Corporate Secretary, or by calling (800) 895-2723.

Audit Committee

The Audit Committee currently consists of Jonathan F. Foster (Chair), Peter R. Dachowski and Jay I. Steinfeld. The Audit Committee met nine times in 2022. Each member of our Audit Committee is independent under applicable NYSE listing standards and meets the heightened standards for independence required by U.S. securities law, including Rule 10A-3 of the Securities Exchange Act of 1934 (the "Exchange Act"). Each member is financially literate under applicable NYSE listing standards and our Board has determined that each of Mr. Foster and Mr. Dachowski is qualified as an audit committee financial expert within the meaning of applicable SEC regulations. The Audit Committee oversees and evaluates and, where necessary or advisable, makes recommendations as to the quality and integrity of the financial statements of the Company, the internal control

and financial reporting systems of the Company, the compliance by the Company with legal and regulatory requirements in respect of financial disclosure, the qualification, independence and performance of the Company's independent registered public accounting firm and the performance of the Company's internal audit functions. In addition, the Audit Committee is directly responsible for the appointment, compensation, retention, termination and oversight of the work of the independent registered public accounting firm (including oversight of the resolution of any disagreements between management and the independent registered public accounting firm regarding financial reporting) for the purpose of preparing audit reports or performing other audit, review or attest services for the Company, subject to any applicable approvals required from our Board or our Shareholders.

Human Resources and Compensation Committee

The Human Resources and Compensation Committee currently consists of Francis M. Scricco (Chair), Peter R. Dachowski, William O. Oesterle, and Barry A. Ruffalo. The Human Resources and Compensation Committee met six times in 2022. Each member of our Human Resources and Compensation Committee is independent under applicable NYSE listing standards and qualifies as a "non-employee director" for purposes of Rule 16b-3 under the Exchange Act. The Human Resources and Compensation Committee reviews and, as it deems appropriate, recommends to the Board policies, practices and procedures relating to the compensation and succession planning for our executive officers and other managerial employees and the establishment and administration of employee benefits plans. The Human Resources and Compensation Committee also exercises all authority under the Company's employee equity incentive plans, subject to any applicable approvals required from our Board or our Shareholders. The Human Resources and Compensation Committee may delegate its authority as it deems appropriate to a subcommittee composed of one or more members. The Human Resources and Compensation Committee has utilized Frederic W. Cook & Co. ("FW Cook") as its independent consulting firm since 2010. For a discussion concerning the processes and procedures for considering and determining executive and director compensation and the role of executive officers and the compensation consultant in determining or recommending the amount or form of executive and director compensation, see "Compensation Discussion and Analysis" and "Director Compensation."

Sustainability and Governance Committee

The Sustainability and Governance Committee currently consists of Jody L. Bilney (Chair), Francis M. Scricco, and Daphne E. Jones. The Sustainability and Governance Committee met five times in 2022. Each member of our Sustainability and Governance Committee is independent under applicable NYSE listing standards. The Sustainability and Governance Committee reviews and, as it deems appropriate, recommends to the Board policies and procedures relating to director and Board committee nominations and corporate governance policies, oversees the Company's ethics and compliance program, reviews policies with respect to risk assessment and risk management and provides oversight for risk management processes, overseeing and monitoring the Company's approach to environmental and social responsibility matters and strategies related to corporate citizenship and sustainability, oversees the Company's strategies and processes related to information security and technology risks (including cybersecurity), assist the Board in overseeing and monitoring the Company's Shareholder engagement program, and establishes and administers the process related to annual assessment of Board, committee and individual director performance. The Sustainability and Governance Committee has oversight with respect to the Company's strategies and processes related to information security matters and is updated by management at each committee meeting. The Company has an information security risk insurance policy and provides periodic information security training to employees of the Company.

BOARD ROLE IN OVERSIGHT OF RISK AND ENVIRONMENTAL AND SOCIAL MATTERS

The Board takes an active role in the oversight of our most significant risks. The Board executes its risk oversight function at the Board level and through delegation to its Board committees. The Board does not view risk in isolation. Risks are considered in virtually every business decision and as part of our business strategy. While the Board and its committees oversee risk management, management is responsible for the day-to-day management of the overall risks facing the Company. A management led enterprise risk management committee meets at least quarterly to assess and review identified risks and efforts being taken to appropriately mitigate risk and consider

MASONITE 2023 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13

BOARD ROLE IN OVERSIGHT OF RISK AND ENVIRONMENTAL AND SOCIAL MATTERS

emerging risk and the potential impact to the Company. The Audit Committee reviews the guidelines and policies governing the process by which risk assessment and risk management are managed by management with the oversight of the Sustainability and Governance Committee. The Audit Committee also reviews the Company's major financial risk exposures and management's actions to monitor and control such exposures. The Board has delegated to the Sustainability and Governance Committee the primary responsibility for overseeing our risk management framework and methods for identifying and managing management's adherence to the framework, including periodic review of the structure and effectiveness of our management risk committee. In overseeing our risk management framework the Sustainability and Governance Committee, together with management, considers the risks and opportunities that impact the long-term sustainability of the Company's business model, including ESG matters, and whether our business strategy is consistent with the Company's risk appetite. The Human Resources and Compensation Committee conducts a compensation plan risk assessment in order to ensure that our compensation plans focus on growth in Shareholder value without incentivizing undue risk. Our Board receives reports from the committees and periodically assesses the enterprise-level risks that face the Company from a strategic point of view and reviews options for risk mitigation. With respect to cyber-security oversight, the Board periodically receives updates on cybersecurity. In addition, at every meeting of the Sustainability and Governance Committee, the Committee receives reports and/or updates from management on the primary cyber-security risks facing the Company and the measures the Company is taking to mitigate such risks. In addition to such periodic reports, the Board and/or the Sustainability and Governance Committee receive updates from management as to changes to the Company's cyber-security risk profile or certain newly identified risks.

COMMITMENT TO SUSTAINABILITY AND CORPORATE RESPONSIBILITY

Our Board, together with management, recognize the importance of ESG matters and how they impact our stakeholders, including our Shareholders, customers, employees, suppliers, and the communities in which we operate. We believe that good business, economic growth, and management of environmental and social matters go hand-in-hand. We are committed to conducting operations and activities in a manner that provides and maintains safe and healthful working conditions, protects the environment and conserves natural resources. We are also committed to the continual improvement of our management of environmental matters and our environmental, health and safety programs. In light of the continued importance of these matters, we have developed a multi-year road map to enhance our ESG programs and disclosures, including assessing potential risks and opportunities of climate change.

In 2019, we published our inaugural Corporate Responsibility Highlights Report. In 2022, we published our 2021 ESG Report, which reports on our nine material topics and other topics important to Masonite. It contains highlights of our achievements from the year, including our Scope 1 and 2 greenhouse gas emissions. Our ESG Report was aligned to the Sustainability Accounting Standards Board Building Products & Furnishings standard and the Task Force for Climate-Related Financial Disclosures Index. In addition, we have issued climate-related disclosures in alignment with CDP Climate Change (formerly the Carbon Disclosure Project) framework and received a B on our 2022 response. To view our ESG policies, reports, and disclosures, and for more information about our sustainability and corporate citizenship programs, including our 2021 ESG Report, please visit the ESG section of our website at www.masonite.com. Such website is not part of this proxy solicitation and is not incorporated by reference into this Proxy Statement.

Our Board and management oversee sustainability matters to ensure that the long-term interests of our Shareholders are being served and to monitor adherence to Masonite's standards and policies relating to corporate responsibility. In 2018, we added formal responsibility for ESG matters to the Sustainability and Governance Committee charter, and management has presented to both the Board and the Sustainability and Governance Committee on issues such as safety, business continuity, and environmental matters. In 2020, we also established a management led ESG Steering Committee with a formal charter and designated subcommittees for Environmental, Social and Governance.

Finally, our Board believes that what is measured matters and, accordingly, our annual cash bonus plan for management has included specific ESG metrics for three consecutive years, which ensures that management is held accountable for our ESG performance.

CORPORATE GOVERNANCE GUIDELINES AND CODE OF ETHICS

CORPORATE GOVERNANCE GUIDELINES AND CODE OF ETHICS

Our Board has adopted Corporate Governance Guidelines that reflect the principles by which we operate. From time to time, the Sustainability and Governance Committee and the Board review and revise our Corporate Governance Guidelines in response to evolving best practices as appropriate. We have also adopted a Values Guide/Code of Conduct (the "Code of Conduct"), which applies to all of our directors, officers and employees. We have posted and intend to continue to post any amendments to or waivers from our Code of Conduct on the Corporate Governance documents page on our website to the extent applicable to our CEO, CFO, Corporate Controller, and any other officer who may function as a Chief Accounting Officer or a director. Our Corporate Governance Guidelines, the Code of Conduct, and other information are available at our website, www.masonite.com, and such information is available in print to any Shareholder without charge, upon request to Masonite International Corporation, 1242 East 5th Avenue, Tampa, FL 33605, Attention: Corporate Secretary, or by calling (800) 895-2723.

Shareholder Engagement

2022 ENGAGEMENT

To ensure the continued creation of long-term value to our Shareholders, we launched a formal, proactive Shareholder program in 2022. This program is additive to our regular, ongoing dialogue with Shareholders throughout the year, and extends beyond earnings-related discussions to topics such as, among other topics, ESG, DEI, risk management, and executive compensation. We recognize the value of engaging with our Shareholders, and intend to be thoughtful about and responsive to Shareholder feedback gained through the process. The Sustainability and Governance Committee assist the Board in overseeing and monitoring the Company's approach to the Shareholder engagement program.

Coinciding with the launch of the program, Company management engaged with key Shareholders in the fall of 2022. We sought contact with our top institutional Shareholders, and received written feedback from several Shareholders and conducted a video conference conversation with one Shareholder representing contact with holders of approximately 6% of our Common Share outstanding despite the program being in its nascent stage. Following each engagement, Shareholder feedback will be assessed by the management leadership team and communicated to the Board and its committees, as applicable. These conversations will influence potential enhancements to our ESG, risk management, executive compensation and other practices, which may ultimately be reflected in our public disclosures. The diagram on the below left depicts the key phases of our Shareholder engagement program, which we expect to be an ongoing process moving forward. The graphic on the below right depicts some of the themes of our shareholder engagement conversations.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

During 2022, Messrs. Scricco, Dachowski, Oesterle and Ruffalo served on the Human Resources and Compensation Committee.

Under the Related Person Transaction Policy, each Related Person Transaction must be approved or ratified in accordance with the guidelines set forth in the policy by the Sustainability and Governance Committee or by the disinterested members of the Board. In considering whether to approve or ratify any Related Person Transaction, the Sustainability and Governance Committee or the disinterested members of the Board, as the case may be, shall consider all factors that in their discretion are relevant to the Related Person Transaction. Additionally, any employment relationship or transaction involving an executive officer and any related compensation must be approved by the Human Resources and Compensation Committee or recommended by the Human Resources and Compensation Committee for its approval.

## Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act, as amended, requires directors, executive officers and beneficial owners of more than ten percent (10%) of our Common Shares to file with the SEC initial reports of ownership and reports of changes in ownership of our Common Shares. Based solely on our review of electronic filings with the SEC of such reports and written representations from our executive officers and directors that no Form 5 is required, we believe that all such reports were submitted on a timely basis during 2022.

## Director Compensation

------

During 2022, the annual non-employee director compensation program was structured as follows:

• Annual cash retainer: $100,000

• Annual equity retainer: $100,000 ($150,000 for the Non-Executive Chairman of the Board)

• Additional annual cash retainer for Sustainability and Governance Committee Chair: $15,000

• Additional annual cash retainer for Audit Committee Chair: $20,000

• Additional annual cash retainer for the Human Resources and Compensation Committee Chair: $17,500

• Additional annual cash retainer for the Non-Executive Chairman of the Board: $70,000

• No meeting fees (Board or Committee)

All cash retainers are payable in equal installments at the beginning of each fiscal quarter. As indicated above, our non-employee directors other than the Non-Executive Chairman of the Board also receive an annual equity retainer of restricted stock units where the number of restricted stock units granted is determined by dividing $100,000 by the fair market value of a Common Share on the grant date. The number of restricted stock units granted to the Non-Executive Chairman of the Board is determined by dividing $150,000 by the fair market value of a Common Share on the grant date. These grants are made annually immediately after a director is elected or re-elected as the case may be, to our Board and will vest on the first anniversary of the grant date, subject to the director's continued service on the Board through the vesting date.

All directors are reimbursed for reasonable costs and expenses incurred in attending meetings of our Board and its committees.

STOCK OWNERSHIP GUIDELINES

We have stock ownership guidelines that require each of our non-employee directors to own meaningful equity stakes in Company stock to further align their economic interests with those of our Shareholders. Our stock ownership guidelines require that our non-employee directors own Common Shares in an amount not less than five times the amount of their annual cash retainer. Compliance with these guidelines is measured once per fiscal year on the last day of the first fiscal quarter. Restricted stock units count as shares for purposes of the guidelines. There is no particular date by which the requisite share ownership level must be achieved. However, until the required level of ownership is achieved, each non-employee director must retain at least fifty percent of the number of Common Shares acquired by the director upon the settlement of any restricted stock units. As of the last measurement date on April 3, 2022, all of the directors owned the number of shares required by the guideline except for Mr. Oesterle and Ms. Jones (both of whom joined the Board in February, 2018), Mr. Steinfeld (who joined the Board in November, 2020) and Mr. Ruffalo (who joined the Board in July, 2021).

NAMED EXECUTIVE OFFICERS

Our Named Executive Officers

This section discusses the compensation of our Chief Executive Officer, our Chief Financial Officer and our other three most highly compensated officers for the fiscal year ended January 1, 2023 (referred to herein as 2022), who are hereafter referred to as our named executive officers or NEOs. For 2022, the following individuals were our NEOs:

• Howard C. Heckes, President and Chief Executive Officer

• Russell T. Tiejema, Executive Vice President and Chief Financial Officer

• Christopher O. Ball, President, Global Residential

• Randal A. White, Senior Vice President, Global Operations and Supply Chain

• Robert A. Paxton, Senior Vice President, Human Resources

EXECUTIVE SUMMARY

Our Business

We are a leading global designer, manufacturer, marketer and distributor of interior and exterior doors for the new construction and repair, renovation and remodeling sectors of the residential and non-residential building construction markets. Since 1925, we have provided our customers with innovative products and superior service at compelling values. As of January 1, 2023, we served over 6,500 customers globally and had over 10,000 employees and contract personnel worldwide.

Executive Compensation Program Attributes

Our executive compensation program is based on an underlying philosophy that compensation should attract, engage and retain high caliber talent, reward performance and align the interests of our executives with the interests of our Shareholders. We execute this philosophy by providing our executives with base salaries, cash bonus awards under our annual cash bonus plan, grants of a combination of performance-based and time-based equity awards under our long-term incentive plan, severance and change in control benefits, and other employee benefits. To focus our NEOs on delivering results, both short- and long-term, a significant amount of their target total direct compensation mix is weighted towards at-risk compensation.

Compensation Best Practices

As part of our compensation philosophy, we have adopted a number of practices to help ensure a balanced and transparent executive compensation structure, including:

• We deliver a majority of our long-term incentive awards in the form of performance-vesting equity awards that are tied to the achievement of challenging financial objectives and stock appreciation rights ()"**SARs**") which only have value if our share price increases, both of which we believe provide an incentive to drive long-term growth in the value of the Company and align with Shareholder interests;

• We have stock ownership guidelines for our NEOs to ensure they maintain a significant investment in our Common Shares, thereby aligning their economic interest with those of our Shareholders;

• We have "clawback" provisions within our equity compensation plans that enable us to recover both cash-based and equity-based incentive compensation from our employees, including our NEOs;

• We have a policy that prohibits pledging and hedging in our Common Shares;

• We do not have any plans or agreements that provide tax gross-ups under Section 280G of the Internal Revenue Code;

EXECUTIVE SUMMARY

• We do not grant any equity awards that provide for "single trigger" vesting on or following a change of control. All equity awards require a qualifying termination following a change of control ("double trigger") in order to accelerate vesting; and

• Our NEOs do not receive excessive or extraordinary perquisites, as we only provide such benefits for reasonable competitive purposes, such as providing newly hired executives with relocation benefits, providing our executives with more comprehensive physical examinations, and providing a capped reimbursement for financial planning, tax planning, and tax preparation services.

2022 Executive Compensation Highlights

---

| | |
|:---|:---|
| Base Salary | • After considering the results of the annual market assessment conducted by FW Cook, the Human Resources and Compensation Committee's independent compensation consultant, and management's recommendation, we approved base salary merit increases for 2022 for each NEO other than Mr. Ball (who joined the Company in September 2021). These increases were approved in connection with the Human Resources and Compensation Committee's desire to recognize individual performance while keeping our NEO's compensation near the peer group median. |
| Annual Cash Bonuses | • In 2022, for those NEOs whose performance was measured using the Corporate Masonite Incentive Plan ("MIP") goals (i.e., Mr. Heckes, Mr. Tiejema, Mr. White, and Mr. Paxton), the MIP annual cash bonus was measured using the following performance measures: Corporate MIP Adjusted EBITDA (weighted 70%) and a balanced scorecard (weighted 30%).<br>• In 2022, for those NEOs whose performance was measured against segment-specific MIP plan goals (i.e., Mr. Ball) the 2022 MIP annual cash bonus was measured using the following performance measures: Segment MIP Adjusted EBITDA (weighted 50%), Corporate MIP Adjusted EBITDA (weighted 20%), and a balanced scorecard (weighted 30%).<br>• In 2022, the MIP annual cash bonus also included an individual performance multiplier of 0.75x to 1.25x in order to drive a continued performance culture. In addition, the Human Resources and Compensation Committee provided Mr. Heckes with a discretionary pool of funding of up to 5% of the target MIP bonus pool to be used for recognition of key performers.<br>• In 2022, we achieved MIP Adjusted EBITDA of $453.0 million, which was slightly above the target level of performance and the Human Resources and Compensation Committee determined that our Corporate balanced scorecard achieved 80% of the target opportunity. As a result, the MIP paid out at 96.1% of target for Corporate Plan participants, including our NEOs other than Mr. Ball. |

| Long-Term Equity Incentive Awards | • In 2022, for our NEOs, a significant portion of their long-term incentive awards were granted in the form of "at risk" performance-based awards, with 60% consisting of performance-based restricted stock units, 10% consisting of SARs, and 30% consisting of time-based restricted stock units. The 2022 performance-based restricted stock units are earned based on incremental annual levels of achievement in Net Sales and Return on Invested Capital over a three-year performance period, subject to certain adjustments as approved by the Human Resources and Compensation Committee. NEO's long-term incentive awards targets are expressed as a dollar amount rather than as a percentage of base salary. For 2022, Mr. Heckes' target was $3.4 million, Mr. Tiejema's target was $900,000, Mr. Ball's target was $825,000, and Messrs. White's and Paxton's targets were each $550,000.<br>• In 2022, each of our NEOs received a one-time out-performance equity award in the form of performance-vesting restricted stock units. These awards are earned based on the achievement of specified Adjusted EBITDA targets over a three-year performance period. In awarding these incremental performance-vesting RSUs, the Human Resources and Compensation Committee sought to incentives our management team, including our NEO's to achieve and maintain record levels of Adjusted EBITDA, while providing an additional retention tool as any earned RSUs are subject to additional vesting requirements. The number of performance-vesting restricted stock units granted to each NEO for this one-time special award is as follows: 28,309 for Mr. Heckes, 16,985 for Mr. Tiejema, and 11,323 for each of Messrs. Ball, White and Paxton. Given the Company's financial results in 2022, the performance vesting conditions for the first 34% of the performance-vesting restricted stock have not been satisfied and will yield zero payout on this first tranche of the special one-time award.<br>• For performance period 2020-2022, performance-vesting restricted stock units were granted to Messrs. Heckes, Tiejema, White and Paxton in 2020, with performance measurements of Adjusted EBITDA Margin and ROIC improvements from 2020 through 2022, with a payout at 133.3% of target. Given his hire date, Mr. Ball did not participate in the 2020 performance-vesting restricted stock unit program. |

2022 Corporate Governance Highlights

Our Board is committed to maintaining sound governance practices and standards with respect to its oversight of our executive compensation program, including the following:

• The Human Resources and Compensation Committee's independent compensation consultant, FW Cook, is retained directly by the Human Resources and Compensation Committee and performs no other services for us;

• Upon request by the Human Resources and Compensation Committee, FW Cook conducted an updated benchmarking study of our executive compensation program in late 2021, and the Human Resources and Compensation Committee considered the results of such study in making compensation decisions in 2022;

• The Human Resources and Compensation Committee reviews our executive compensation program annually to confirm that such program does not encourage unnecessary or excessive risk-taking; and

• The Human Resources and Compensation Committee follows an equity grant policy that sets forth the timing and approvals required for equity grants.

INTRODUCTION TO COMPENSATION DISCUSSION & ANALYSIS

INTRODUCTION TO COMPENSATION DISCUSSION & ANALYSIS

Our Compensation Discussion and Analysis ("CD&A") explains the philosophy and objectives of our compensation program and our process for setting compensation for our NEOs for 2022.

Our executive compensation program is overseen by the Human Resources and Compensation Committee. As discussed in greater detail below, we offer our NEOs a balanced compensation structure, comprised of the following components:

• Annual base salary;

• Annual cash bonuses (MIP);

• Long-term equity incentive awards (performance-based restricted stock units, time-based restricted stock units and SARs);

• Severance and change in control benefits; and

• Other employee benefits.

In making its decisions on an executive's compensation, the Human Resources and Compensation Committee considers the nature and scope of all elements of the executive's total compensation package, the executive's responsibilities and his or her effectiveness in supporting our key strategic, operational and financial goals (but does not assign any specific weighting to any of the items considered).

COMPENSATION DISCUSSION & ANALYSIS

Executive Compensation Objectives

Our executive compensation program is overseen by the Human Resources and Compensation Committee. The Human Resources and Compensation Committee consults with the Board in determining the compensation package of our Chief Executive Officer and has ultimate responsibility for determining the compensation for all of the NEOs. In making its compensation decisions, the Human Resources and Compensation Committee considers, among other things, market data and trends, input from the Human Resources and Compensation Committee's independent compensation consultant FW Cook (whose role is discussed below), and, with respect to the NEOs other than our Chief Executive Officer, the recommendations of our Chief Executive Officer (as discussed in more detail below).

The Human Resources and Compensation Committee is responsible for establishing and annually reviewing the overall compensation philosophy of the Company for its executive officers. The key principles guiding the Human Resources and Compensation Committee in making compensation determinations are as follows:

• We offer a total compensation program comprised of a fixed base salary and variable annual and long-term incentive compensation linked to share price and business performance, designed to attract, engage, retain and motivate talented executives to deliver the Company's financial and operating performance objectives and long-term vision.

• To align the interests of management with those of our Shareholders, our pay mix is weighted in favor of at-risk compensation (i.e., our annual cash bonuses and long-term equity awards may not be earned if performance goals are not met and may have reduced or no value if the price of our stock declines).

• Pay for performance is an important component of our compensation philosophy. Consistent with this focus, our annual cash incentive and long-term equity incentive program designed with pay opportunities linked to Company performance against pre-established goals and, for the MIP, the balanced scorecard (i.e., pay outcomes determined by performance above or below target goals with payouts capped and potential for zero payout below threshold performance) and stock price.

Compensation Philosophy and Pay Mix

The Human Resources and Compensation Committee strives to provide pay opportunities that align within a competitive range, generally defined as +/- 15% of the median, of the market for executive talent, as determined

MASONITE 2023 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;27

COMPENSATION DISCUSSION & ANALYSIS

using both our peer group and general industry market survey data, and considers competitive compensation practices and other relevant factors such as experience, contribution, internal equity, and performance in setting each NEO's target total direct compensation. Target total direct compensation represents the sum of target total cash compensation (base salary plus target annual incentive bonus) and target long-term equity incentive awards. Given our performance-based program, the actual amount of compensation realized will be determined by our ability to perform against pre-established performance goals and, for the MIP, the balanced scorecard, and by increasing our stock price.

Our executive compensation program provides for a mix of performance-based and fixed compensation elements and our Human Resources and Compensation Committee strives to achieve an appropriate balance between these two types of compensation, as well as an appropriate mix of cash and equity-based compensation. The mix of compensation elements is designed to reward individual and team performance and enterprise value growth and is weighted towards at-risk compensation, both in the form of performance-based annual cash bonuses and equity-based compensation, including performance-based restricted stock units, time-based restricted stock units, and SARs.

The charts below illustrate the target total direct compensation for 2022 for Mr. Heckes and the average of the other four NEOs, in each case, excluding the special one-time grant of performance-vesting restricted stock units on August 3, 2022.

Prior Year's Shareholder Advisory Vote

Each year, the Human Resources and Compensation Committee considers the outcome of the Shareholder advisory vote on executive compensation when making future decisions relating to the compensation of our NEOs and our executive compensation program and policies. We believe that our Shareholders recognize the positive attributes of our executive compensation program. We received strong support for our executive compensation program from our Shareholders at our last annual meeting of Shareholders, at which, approximately 96% of the votes cast for the "say on pay" proposal were in favor of the 2021 compensation for our NEOs.

ROLE OF OUR HUMAN RESOURCES AND COMPENSATION COMMITTEE

ROLE OF OUR HUMAN RESOURCES AND COMPENSATION COMMITTEE

The Human Resources and Compensation Committee makes compensation decisions for our NEOs after reviewing our performance for the preceding fiscal year, our short- and long-term strategies, and current economic and market conditions, and carefully evaluating each NEO's performance during the preceding fiscal year against established organizational goals, leadership qualities, operational performance, business responsibilities, tenure, current compensation arrangements and long-term potential to enhance enterprise value. The Human Resources and Compensation Committee takes a holistic view in its assessment of executive compensation arrangements, taking into consideration the foregoing factors and Shareholder considerations, not necessarily relying on any one factor exclusively in determining compensation for our NEOs. In making compensation decisions, the Human Resources and Compensation Committee receives advice from FW Cook and input from our Chief Executive Officer (and other executive officers), as further discussed below.

ROLE OF OUR CHIEF EXECUTIVE OFFICER AND OTHER EXECUTIVE OFFICERS

Our Chief Executive Officer reviews the base salaries of our NEOs (other than himself) on an annual basis and, if applicable, recommends base salary adjustments to the Human Resources and Compensation Committee, based on each NEO's performance and responsibilities. The Chief Executive Officer confers with our Senior Vice President of Human Resources and together they consider applicable market data provided by FW Cook. In addition, the Chief Executive Officer and our Senior Vice President of Human Resources provide the Human Resources and Compensation Committee with input regarding our annual cash incentive plan (as discussed below) and equity grants for executive officers, including but not limited to recommendations regarding eligibility for such grants and the size of the applicable grant. Additionally, our Executive Vice President and Chief Financial Officer provides input to our Chief Executive Officer and the Human Resources and Compensation Committee with respect to the financial performance aspects of our annual cash incentive plan and any performance-based equity awards. Although our Chief Executive Officer regularly attends meetings of the Human Resources and Compensation Committee, he recuses himself from those portions of the meetings related to his compensation. The Human Resources and Compensation Committee, in consultation with our Board, is exclusively responsible for determining any base salary changes and for making any other compensation decisions with respect to our Chief Executive Officer.

ROLE OF COMPENSATION CONSULTANT

Our independent consulting firm, FW Cook, is engaged by, and reports directly to, the Human Resources and Compensation Committee. FW Cook provides our Human Resources and Compensation Committee with input and guidance on all components of our executive compensation program. Except for services provided to the Human Resources and Compensation Committee related to executive compensation and non-employee director compensation, FW Cook did not provide any additional services to the Company during 2022.

The Human Resources and Compensation Committee has evaluated whether any work performed by FW Cook raised any conflict of interest and determined there was no conflicts of interest during 2022.

BENCHMARKING

Peer Group Review and Benchmarking Study

The Human Resources and Compensation Committee requests FW Cook to review our peer group used to benchmark executive compensation on an annual basis and recommend changes as appropriate. In 2021, FW Cook conducted an updated peer group review and examined the following general criteria in order to support its recommendation: (i) operational fit reflecting companies in the building products industry and subject to similar economic opportunities and pressures as well as similar business and performance characteristics; (ii) financial scope reflecting companies of similar size and scale (with size for purposes of peer group development generally defined as 1/3 to 3 times Masonite's revenue and market cap), in addition to relevant secondary measures such as total assets and net income; (iii) competitor companies with whom Masonite competes for executive talent and that operate in similar economic markets, (iv) public companies listed on

---

In late 2021, upon request from the Human Resources and Compensation Committee, FW Cook conducted an updated benchmarking study of our executive compensation based on the 2022 Peer Group, as well as other market information from third-party surveys. The Human Resources and Compensation Committee took the results of this benchmarking study into account in making compensation decisions in 2022. After reviewing this study, the Human Resources and Compensation Committee determined that target total direct compensation and target long-term incentive compensation were within the competitive range of market median for the CEO and for all other NEOs as a group. This determination took into account the base salary increases for each NEO described below.

The Human Resources and Compensation Committee approved base salary adjustments in February 2022 for Messrs. Heckes, Tiejema, White and Paxton after taking into consideration the results of the 2021 benchmarking study and other factors (as further described below in the "Elements of Our Executive Compensation Program - Base Salary" section).

For purposes of determining the size of the long-term incentive awards that were granted to our NEOs in February 2022 (as described below in the "Long-Term Equity Incentive Awards" section), the Human Resources and Compensation Committee considered the results of the 2021 benchmarking study as a factor, in addition to individual performance levels and responsibilities and also considered the goal of providing an appropriate long-term retention incentive for the NEOs (none of these factors were individually weighted).

The Human Resources and Compensation Committee intends to continue to provide compensation opportunities that generally align each NEOs target total direct compensation within a competitive range of the market median and expects that a significant portion of each NEOs total compensation package will continue to be focused on rewarding long-term future performance through a combination of at-risk cash and equity incentive awards.

ELEMENTS OF OUR EXECUTIVE COMPENSATION PROGRAM

For 2022, our executive compensation program consisted of the following elements:

Base Salary

Base salary is designed to provide our NEOs with a fixed amount of income that is competitive in relation to the responsibilities of each NEO's position. In February 2022, the Human Resources and Compensation Committee approved base salary merit adjustments for Messrs. Heckes, Tiejema, White and Paxton after considering prevailing market practices for executive merit adjustments and the results of the 2021 benchmarking study. The merit adjustments for the referenced NEOs, which were effective February 28, 2022, reflected the Human Resource and Compensation Committee's desire to enhance our ability to retain them and to reward them for their performance. Mr. Ball's base salary was not increased due to the fact that he joined the Company effective September 7, 2021.

Annual Cash Incentive Bonus

General

The executive compensation program for our NEOs includes our MIP. The MIP is a short-term incentive plan which provides executive officers with a cash bonus award based on the achievement of annual performance goals. The Human Resources and Compensation Committee approves the MIP each year, including the funding threshold, the maximum bonus that may become payable to each participant, the applicable performance goals, and the weighting, payout parameters and specific measures for each performance goal. Each fiscal year, our Chief Executive Officer, following discussions with our Senior Vice President of Human Resources and our Executive Vice President and Chief Financial Officer, makes recommendations to the Human Resources and Compensation Committee for the MIP performance goals (and the applicable targets for achievement of each such performance goal at threshold, target and maximum levels of performance) applicable to all NEOs (including himself) as well as any proposed changes in the terms of the MIP for that fiscal year. The Human Resources and Compensation Committee considers these recommendations, as well as input from FW Cook regarding both current incentive plan design trends and our Chief Executive Officer's recommendations, in approving the design of the MIP for each fiscal year. Our Chief Executive Officer has no involvement in the determination of an NEO's actual MIP payout each year, including his own, other than the assignment of an Individual Performance Multiplier for each of his direct reports, inclusive of the NEOs.

2022 Masonite Incentive Plan

After considering management's recommendations and input from FW Cook, the Human Resources and Compensation Committee determined that the performance measures for the 2022 MIP would focus on our ability to grow total Company profitability (MIP Adjusted EBITDA, as defined in the "MIP and LTIP Definitions and Reconciliation" section below) and our ability to improve organizational performance based on a balanced scorecard consisting of operational, product development, and ESG focus areas (the "Balanced Scorecard") with the achievement on the Balanced Scorecard being determined in the discretion of the Human Resources and Compensation Committee, based on the Company's performance in the focus areas. The Human Resources and Compensation Committee determined that the 2022 MIP Adjusted EBITDA metric would be weighted 70% and the 2022 Balanced Scorecard would be weighted at 30% of the MIP to continue to align the 2022 MIP with Shareholder interests and the Company's strategic priorities for 2022. However, as further discussed below, for Mr. Ball, the 2022 MIP annual cash bonus was instead measured using Segment MIP Adjusted EBITDA (weighted at 50%), Corporate MIP Adjusted EBITDA (weighted at 20%), and the Balanced Scorecard (weighted at 30%).

In addition, in 2022, the Human Resources and Compensation Committee included an individual Performance Multiplier ("IPM") for MIP participants, including our NEOs, to drive a performance culture. The IPM is a multiplier of 0.75x to 1.25x, tied to individual performance objectives and results. The IPM is calculated after the Company's financial results and the corresponding baseline payout levels have been cleared. The Human Resources and Compensation Committee will consider recommendations made by the CEO for the NEOs and will decide the appropriate IPM for the CEO. The CEO can recommend and the Human Resources and Compensation Committee can reallocate funds away from any NEO with an IPM < 1.0x to the remaining pool of NEOs. The pro-rated portion of MIP funding for any performance-managed NEO termination during the year may also be reallocated to the

pool of remaining NEOs. In addition, pool funding of up to 5% of MIP Target may be used by the CEO to make additional payments to key performers.

Corporate MIP Structure

For 2022, for each NEO (other than Mr. Ball) the MIP performance goals and the individual weighting assigned to each performance goal as a percentage of the applicable target bonus were established as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;Corporate MIP Structure | Weighting |
| &nbsp;&nbsp;&nbsp;&nbsp; Corporate MIP Adjusted EBITDA | 70% |
| &nbsp;&nbsp;&nbsp;&nbsp; Corporate Balanced Scorecard | 30% |
| &nbsp;&nbsp;&nbsp;&nbsp; Individual Performance Multiplier | 0.75x to 1.25x |

For 2022, the MIP required achievement of a minimum MIP Adjusted EBITDA of $375 million in order for any MIP bonuses to become payable (even if the Human Resources and Compensation Committee exercised its discretion with respect to the Balanced Scorecard). For 2022, the payout percentages for MIP Adjusted EBITDA performance goal and the Balanced Scorecard goal for performance at threshold, target and maximum were set as follows:

Following the completion of 2022, the MIP payout pool was calculated using data derived from the audited financial results. In 2022, our Corporate MIP Adjusted EBITDA performance was $453.0 million resulting in performance of 100.2% of target. Our North American Residential MIP Adjusted EBITDA performance was $465.9 million, resulting in performance of 110.9% of target. Using a straight-line interpolation method, these financial results were then interpolated between the target and maximum levels and yielding a plan payout of 103.0% for the Corporate MIP Adjusted EBITDA performance goal and a plan payout of 200.0% for the North American Residential MIP Adjusted EBITDA performance goal.

The 2022 Balanced Scorecard included performance considerations related to launch and commercialization of new products, development of alternative sales channels, and advancement of ESG initiatives including safety, diversity and inclusion. After careful review, the Human Resources and Compensation Committee decided that the 2022 performance level for the Corporate Balanced Scorecard metrics was achieved at 80% of target for the Corporate plan and at 75% of target for the North American Residential segment plan.

Based on performance against the applicable pre-established MIP Adjusted EBITDA performance goals and consideration of the Balanced Scorecard achievement, the 2022 Corporate MIP bonus payment percentage was calculated as follows:

---

Long-Term Equity Incentive Awards

February 2022 Annual Long-Term Incentive Grant

The Human Resources and Compensation Committee believes that a significant portion of the equity awards granted to our executive officers should be earned based on the level of our performance pursuant to the financial and operating objectives over a three-year performance period as described below. Tying a significant portion of the annual equity grants to our long-term performance serves to align a greater portion of our NEOs' total direct compensation to the achievement of our long-term financial and operating performance objectives over a three-year period and serves as a balance to the MIP, which measures our performance over a one-year period. For 2022, the Human Resources and Compensation Committee determined that the target equity value granted to each NEO would consist of 60% restricted stock units subject to performance-based and time-based vesting conditions, 30% restricted stock units subject only to time-based vesting conditions, and 10% SARs subject only to time-based vesting conditions but which only retain value if our share price increase above the exercise price.

After taking into consideration the results of the 2021 benchmarking study, in addition to individual performance levels and responsibilities and providing an appropriate long-term retention incentive for the NEOs (none of which factors were individually weighted), the Human Resources and Compensation Committee approved target values for long-term incentive grants in 2022 as follows.

Performance-Vesting Restricted Stock Units

One-half of the performance-vesting restricted stock units vest on the third anniversary of the date of grant based on the annual improvement (expressed in basis points) in Net Sales during each year of the three-year performance period of 2022 through 2024, with a baseline number being set each year using the year-end results of the prior year. At the end of the three-year performance period, the final results are calculated using the arithmetic average of the results of the three one-year performance periods, with 100% of the units vesting upon achievement at the target level, 50% of the units vesting for performance at the threshold level, and 200% of the units vesting for performance at or above the maximum level. The remaining one-half of the performance-vesting restricted stock units vest on the third anniversary of the date of grant based on the annual improvement (expressed in basis points) in Return on Invested Capital during each year of the three-year performance period of 2022 through 2024, with a baseline number being set each year using the year-end results of the prior year. At the end of the three-year performance period, the final results are calculated using the arithmetic average of the results of the three one-year performance periods, with 100% of the units vesting upon achievement at the target level, 50% of the units vesting for performance at the threshold level, and 200% of the units vesting for performance at or above the maximum level. In each case, straight-line interpolation will be used to determine the number of units that will vest if the level of achievement is between threshold and target or between target and maximum and any outstanding units that do not vest once the applicable level of performance has been determined will be automatically forfeited. For purposes of this grant, "**Net Sales**" and "**Return on Invested Capital**" are defined in the "MIP and LTIP Definitions and Reconciliation" section below. The Human Resources and Compensation Committee believes that Net Sales and Return on Invested Capital are the most appropriate metrics for measuring financial performance under the LTIP because they encourage management to focus on actions to improve the long-term financial health and performance of the Company. With respect to Net Sales, the Human Resources and Compensation Committee selected this metric to incentivize growth of the organization through expanded market share and introduction of new products. With respect to Return on Invested Capital, the Human Resources and Compensation Committee selected this metric to incentivize management to achieve growth in an efficient manner while optimizing the amount of investment required to attain desired higher profitability. We believe that these performance targets will be challenging to achieve and will require substantial efforts from management in order to achieve them.

Time-Vesting Restricted Stock Units

We grant a portion of the annual long-term incentive grant in the form of time-vesting restricted stock units to help build ownership in our Company stock and to aid in our ability to retain our management team over a longer time horizon. The time-vesting restricted stock units vest over three years, with 33% vesting on the first anniversary of the date of grant, 33% on the second anniversary and 34% on the third anniversary.

Stock Appreciation Rights

We also grant a portion of the annual long-term incentive grant in the form of SARs in order to encourage actions to increase the value of the Company's stock price, to help build stock ownership in our Company stock and to aid in our ability to retain our management team over a longer time horizon. The SARs vest over three years, with 33% vesting on the first anniversary of the date of grant, 33% on the second anniversary and 34% on the third anniversary and expire 10 years after grant. Upon exercise, the SARs are settled in unrestricted Common Shares having an aggregate fair market value equal to the positive difference between the fair market value of a Common Share on the exercise date and the exercise price of the SAR multiplied by the number of shares for which the SAR is exercised. The exercise price of the SARs granted to the NEOs is not less than the fair market value of a Common Share on the grant date. The number of SARs granted is determined using the Black-Scholes model which calculates the current economic value of a SAR using assumptions that include the exercise price, the term of the award, a risk-free rate of interest, dividend yield, and market volatility.

Each of the awards described above are subject to accelerated vesting under certain circumstances as described below in the "Potential Payments on Termination or Change in Control" section.

2022 Performance-Based Out-Performance Awards

On August 3, 2022, the Human Resources and Compensation Committee made a special one-time grant of performance-vesting restricted stock units under the 2021 Plan to each of Messrs. Heckes, Tiejema, Ball, White and Paxton. This special grant was designed to enhance our ability to retain our NEOs by motivating them to achieve and maintain record levels of EBITDA performance.

The total number of performance-vesting restricted stock units granted was based on the total size of the grant divided by the closing price of our Common Shares on August 3, 2022, and is as follows:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;Executive | Performance-Vesting Restricted Stock Units&nbsp;&nbsp;&nbsp;&nbsp; | Performance-Vesting Restricted Stock Units&nbsp;&nbsp;&nbsp;&nbsp; |

| &nbsp;&nbsp;&nbsp;&nbsp; Randal A. White |  | 11323 |
| &nbsp;&nbsp;&nbsp;&nbsp; Robert A. Paxton |  | 11323 |

---

This special performance-vesting restricted stock unit grant will vest upon the satisfaction of the below described "Performance Vesting Condition", subject to the NEOs continued employment with the Company until August 3, 2025. To satisfy the Performance Vesting Condition for the first tranche representng 34% of the performance-vesting restricted stock unit awards, the MIP Adjusted EBITDA for the Company's 2022 fiscal year must equal or exceed $500 million (excluding payments under a cash retention program adopted by the Human Resources and Compensation Committee on the same date on which the special performance-vesting restricted stock unit grants were made in which the NEOs are not eligible to participate) and satisfy the Performance Vesting Condition for the remaining 66% of the performance-vesting restricted stock unit awards, the MIP Adjusted EBITDA for either the Company's 2023 or 2024 fiscal year must equal or exceed $500 million. Any performance-vesting restricted stock unit awards for which the Performance Vesting Condition is not satisfied are automatically forfeited on the date on which the Human Resources and Compensation Committee confirms that the applicable level of MIP Adjusted EBITDA was not achieved (and is no longer capable of being achieved within the applicable performance period). Except as described in the following sentence, even if a performance-vesting restricted stock unit award has satisfied the Performance Vesting Condition, performance-vesting restricted stock units will be automatically forfeited upon an NEO's termination of employment with the Company for any reason if such termination occurs prior to August 3, 2025. The award agreements governing the performance-vesting restricted stock unit awards include the same accelerated vesting provisions related to death and disability and in connection with a change in control that apply to the Company's annual equity award agreements.

Given the Company's Adjusted EBITDA financial results in 2022, the Performance Vesting Condition for the first tranche of 34% of the performance-vesting restricted stock unit awards was not achieved and no payout will be awarded for the first tranche of the special one-time award.

2020 Performance-Vesting Restricted Stock Unit Award

On February 25, 2020, the Human Resources and Compensation Committee granted the following target number of performance-vesting restricted stock units to the NEOs: Mr. Heckes – 17,549, Mr. Tiejema – 5,161, Mr. White – 2,993, and Mr. Paxton – 2,787 ("2020 PRSUs"). Mr. Ball did not join the Company until September 7, 2021, and therefore did not receive an award of 2020 PRSUs. As described under the "Performance-Vesting Restricted Stock Units" section of our proxy statement for our 2021 annual meeting of Shareholders, 50% of the 2020 PRSUs vested on February 25, 2023 based on the annual improvement (expressed in basis points) in LTIP Adjusted EBITDA Margin achieved during each year of the three-year performance period of 2020 through 2022, with a baseline number being set each year using the year-end results of the prior year. The remaining one-half of the 2020 PRSUs vested on February 25, 2023 based on the annual improvement (expressed in basis points) in Return on Invested Capital achieved during each year of the three-year performance period, with a baseline number being set each year using the year-end results of the prior year. In each case, at the end of the three-year

ELEMENTS OF OUR EXECUTIVE COMPENSATION PROGRAM

performance period, the final results were calculated using the arithmetic average of the three one-year performance periods, with 100% of the 2020 PRSUs eligible to vest upon achievement at the target level, 50% of the 2020 PRSUs eligible to vest for performance at the threshold level, and 200% of the 2020 PRSUs eligible to vest for performance at the maximum level (straight-line interpolation is used to determine the number of 2020 PRSUs that are eligible to vest if the level of achievement is between threshold and target or between target and maximum).

With respect to the 2020 PRSUs:

• Performance Year 1 achieved 200% based on year-over-year improvement in Adjusted EBITDA Margin of 349 basis points (yielding attainment of the maximum performance level) and year-over year improvement in Return on Invested Capital of 328 basis points (yielding attainment of the maximum performance level); and

• Performance Year 2 achieved 100% based on a year-over year decrease in Adjusted EBITDA Margin of 33 basis points (which resulted in performance not attaining the threshold level) and a year-over-year improvement in Return on Invested Capital of 232 basis points which (yielding attainment of the maximum performance level); and

• Performance Year 3 achieved 100% based on a year-over-year decrease in Adjusted EBITDA Margin of 44 basis points (which resulted in performance not attaining the threshold level) and year-over-year improvement in Return on Invested Capital of 356 basis points (yielding attainment of the maximum performance level).

As a result, the 2020 PRSUs vested a 133.3% of the target number of 2020 PRSUs on February 25, 2023.

As was the case with determining payments under the MIP for each such year and as an "other adjustment" approved by the Human Resources and Compensation Committee as permitted by the terms of the 2020 PRSUs, in determining the amount of LTIP Adjusted EBITDA Margin and Return on Invested Capital for 2020, the Human Resources and Compensation Committee excluded the impact of $40.55 million for an accrual related to the settlement of two class action antitrust lawsuits brought against the Company in 2018.

Timing of Equity Grants

The Human Resources and Compensation Committee follows an equity grant policy that sets forth the timing and approvals required for equity grants. Pursuant to this policy, the Human Resources and Compensation Committee typically makes annual awards of equity at its first scheduled meeting taking place after the release of earnings for the fourth fiscal quarter and the year (generally at the end of February), which meeting date is set in advance. The Board of Directors and the Human Resources and Compensation Committee have in the past made, and may in the future make, limited grants of equity on other dates in order to recognize exceptional performance or contributions, to help retain key employees, to compensate an employee in connection with a promotion, or to compensate newly hired executives for equity or other benefits lost upon termination of their previous employment or to otherwise induce them to join the Company. Our Board and the Human Resources and Compensation Committee may make the foregoing "off-cycle" equity grants to employees who are below the executive level on (i) the last business day prior to the 15th day of each month or (ii) the last business day of each month, whichever date first follows the applicable approval date for such awards. Grants to newly hired or promoted executive level employees are made at meetings of our Board or the Human Resources and Compensation Committee, as the case may be, at which such new hire or promotion is to be considered, and in accordance with applicable laws and regulations. Recognition or special retention grants to executive level employees are made at meetings of our Board or the Human Resources and Compensation Committee, as the case may be, at which such recognition or special retention is to be considered, and in accordance with applicable laws and regulations.

The Human Resources and Compensation Committee has delegated to Mr. Heckes the authority to make limited "off-cycle" grants to employees below the executive level of the types and on the pre-established grant dates described above.

STOCK OWNERSHIP GUIDELINES

STOCK OWNERSHIP GUIDELINES

We have stock ownership guidelines that require each of our NEOs and all executive officers to own meaningful equity stakes in the Company's stock to further align their long-term economic interests with those of our Shareholders. Our stock ownership guidelines require that (1) our Chief Executive Officer owns Common Shares in an amount not less than five (5) times his base salary and (2) all other executive officers (including our NEOs) own Common Shares in an amount not less than three (3) times their respective base salaries. Compliance with these guidelines is measured once per fiscal year on the last day of the first quarter. Vested SARs and all vested and unvested time-based restricted stock units count as shareholdings for purposes of the guidelines, but unvested SARs do not count. Performance-based restricted stock units only count towards the guideline if and when earned. There is no particular date by which the requisite share ownership level must be achieved; however, until the required level of ownership is achieved, each executive must retain at least fifty percent of the number of Common Shares acquired upon the exercise of SARs or the settlement of any restricted stock units (net of shares forfeited to pay any applicable exercise price and to satisfy any applicable tax withholding). All NEOs had achieved the required level of stock ownership as of the 2022 measurement date except for Mr. Ball who joined the Company in September, 2021.

SEVERANCE AND CHANGE IN CONTROL BENEFITS

Each NEO is entitled to receive severance benefits under the terms of his or her employment agreement upon either termination by us without cause or a resignation by the NEO for good reason. We provide these severance benefits in order to provide an overall compensation package that is competitive with that offered by other companies with whom we compete for executive talent. Additionally, such severance benefits allow our executives to focus on our objectives and the interests of our Shareholders without concern for their employment security in the event of a termination.

The severance benefits provided upon a qualifying termination of an NEO's employment in connection with a change in control are higher than severance benefits provided under other qualifying termination events, which is consistent with market practice. The Human Resources and Compensation Committee approved these enhanced change in control severance benefits because it considers maintaining a stable and effective management team to be an important factor to protecting and enhancing the best interests of the Company and its Shareholders. To that end, the Human Resources and Compensation Committee recognizes that the possibility of a change in control may exist from time to time, and that this possibility, and the uncertainty and questions it may raise among management, could result in the departure or distraction of management to the detriment of the Company and its Shareholders. Accordingly, the enhanced severance benefits have been put in place to encourage the attention, dedication and continuity of members of our management team to their assigned duties without the distraction that may arise from the possibility or occurrence of a change in control and concern for their employment security in the event of a termination.

OTHER COMPENSATION

We provide the following benefits to our NEOs on the same basis provided to all of our U.S.-based employees:

• medical, dental and vision insurance;

• 401(k) retirement savings plan;

• short- and long-term disability, life insurance, accidental death and dismemberment insurance;

• health, limited purpose health and dependent care flexible spending accounts and/or a health care saving account; and

• various voluntary supplemental insurance products.

Additionally, we provide our executives with more comprehensive physical examinations. Also, upon the hiring of a new executive, we may provide such executive with certain relocation benefits. Each of our NEOs and certain other executives are eligible to participate in a non-qualified deferred compensation plan which permits the NEO

38&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2023 PROXY STATEMENT MASONITE

Executive Compensation

OTHER COMPENSATION

to defer base salary and/or bonuses. Finally, each NEO is provided a reimbursement benefit of up to $10,000 per calendar year (without tax gross-up) for financial planning, tax planning, and tax preparation services.

We believe these benefits are consistent with those offered by companies with which we compete for employees.

CLAWBACK POLICIES

Management Incentive Plan

We have a clawback policy under the MIP, which provides that if an employee engages in (i) certain conduct during a plan year which is injurious to the Company or its reputation, (ii) illegal acts, theft, fraud, intentional misconduct or gross negligence related to the employee's position with the Company or (iii) fraud, gross negligence, or intentional or willful misconduct that contributes to the Company's financial or operational results that are used to determine the extent to which any MIP award is payable being misstated (regardless of whether we are required to prepare an accounting restatement) that is discovered during or within three years after the relevant plan year, the employee will forfeit his or her right to any MIP award for that plan year and will be required to return to us any amounts relating to previously paid MIP awards for such plan year. The plan administrator of the MIP is responsible for determining whether a recoverable event has occurred based on relevant facts and circumstances. The compensation recovery will be in addition to any other remedies available to the Company for any such behavior.

Equity Incentive Plans

The award agreements under the 2012 Plan provided, and the award agreements under the 2021 Plan provide, that if we determine that a participant has materially violated any of the participant's covenants regarding non-disclosure of confidential information and, during the applicable period of time following such participant's termination of employment as specified in such award agreement, non-competition or non-solicitation of employees, then the following will result:

• any outstanding awards, whether vested or unvested, will immediately be terminated and forfeited for no consideration;

• if shares have already been distributed to the participant but the participant no longer holds some or all of such shares, the participant must repay us, in cash, an amount equal to the sum of (i) the total amount of any cash previously paid to the participant in respect of the award and (ii) the total amount of any value received by the participant upon any sale of the shares; and

• if shares have been distributed to the participant and the participant continues to hold some or all of the shares, the participant will transfer such shares to the company for no consideration.

Additionally, equity awards granted under the 2012 Plan after December 31, 2014 are subject to, and all equity awards granted under the 2021 Plan are subject to, a clawback policy in accordance with the same terms in effect for cash-based incentive compensation under the MIP as described above.

ACCOUNTING AND TAX IMPLICATIONS

As a general matter, the Human Resources and Compensation Committee always takes into account the various tax and accounting implications of compensation. When determining amounts of equity grants to executives and employees, the Human Resources and Compensation Committee also takes into consideration the accounting treatment of such grants.

We account for stock-based compensation in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 718 Compensation—Stock Compensation, which requires us to recognize compensation expense for share-based payments. The Human Resources and Compensation Committee considers FASB ASC Topic 718 in determining the amounts of long-term incentive grants to executives and employees.

(1) Value realized on exercise of SARs is calculated based on the difference between the per share price of our stock at the time of exercise and the exercise price of such SARs.

(2) Value realized on vesting of restricted stock units is calculated by multiplying the number of restricted stock units that vested by the per share price of our stock on the applicable vesting date.

Deferred Compensation Plan

The Masonite International Corporation Deferred Compensation Plan ("Deferred Compensation Plan") is an unfunded nonqualified deferred compensation plan that permits certain key employees to defer a portion of their compensation to a future time. Eligible employees may elect to defer a portion of their base salary, bonus and/or restricted stock units and eligible directors may defer a portion of their director fees or restricted stock units under the Deferred Compensation Plan. All contributions to the Deferred Compensation Plan on behalf of the participant are fully vested (other than restricted stock unit deferrals which remain subject to the vesting terms of the applicable equity incentive plan) and are placed into a grantor trust, commonly referred to as a "rabbi trust." Although we are permitted to make matching contributions under the terms of the Deferred Compensation Plan, we have not elected to do so. The Deferred Compensation Plan invests the deferred base salary and bonus contributions in diversified securities from a selection of investments chosen by the participants who may periodically reallocate the assets in their respective accounts. Participants are entitled to receive the benefits in their accounts upon separation of service or upon a specified date, with benefits payable as a single lump sum or in annual installments. In the event of a change in control, each participant's account will be distributed in the form of a single lump-sum payment on the second anniversary of the change in control, unless such participant elects, during the 12-month period beginning on the change in control, to receive a single lump-sum payment or installments commencing on either (i) any specified date that is at least 5 years after the second anniversary of the change in control or (ii) the seventh anniversary of the change in control. In 2022, none of our NEOs elected to defer their compensation under the Deferred Compensation Plan. Additionally, none of our NEOs have earnings, withdrawals, or an aggregate balance under the Deferred Compensation Plan.

POTENTIAL PAYMENTS ON TERMINATION OR CHANGE IN CONTROL

POTENTIAL PAYMENTS ON TERMINATION OR CHANGE IN CONTROL

*NEO Employment Agreements* 

The employment agreements entered into with each of our NEOs entitle them to receive the payments and benefits upon each termination and change in control event described below.

*Termination without cause or for good reason, other than in connection with a change in control*

If the employment of an NEO is terminated by us other than for cause or disability (as defined below), or if an NEO resigns for good reason (as defined below), and such termination is not in connection with a change in control, the NEO will be entitled to receive:

• a lump sum payment of an amount equal to a pro-rata portion of the annual bonus, based on actual performance, that the NEO would have been paid if he had remained employed by us; and

• continued payment of base salary for 24 months if the date of termination is more than two years after the NEO became employed by the Company, and for 12 months if the date of termination is less than two years after the NEO became an employee of the Company; and

• continued participation in our medical, dental and hospitalization coverage for 12 months on the same terms and conditions as immediately prior to such NEO's date of termination (i.e., at active employee rates).

*Termination without cause or for good reason in connection with a change in control*

In the event the employment of an NEO is terminated by us other than for cause or disability, or by an NEO for good reason, either during the two year period following a change in control or if such NEO's employment is terminated at the request of a third party or otherwise arises in anticipation of a change in control, the NEO will be entitled to receive:

• a lump sum payment of an amount equal to a pro-rata portion of the annual bonus, based on actual performance, that the NEO would have been paid if the NEO had remained employed by us; and

• a lump sum payment equal to two times the sum of base salary and the average amount of such NEO's annual bonuses earned during the two calendar years immediately preceding the date of termination; and

• continued participation in our medical, dental and hospitalization coverage for 24 months on the same terms and conditions as immediately prior to such NEO's date of termination (i.e., at active employee rates).

If any payments or benefits provided to an NEO in connection with a change in control are subject to excise taxes as a result of the application of Sections 280G and 4999 of the Internal Revenue Code, such payments and benefits will be reduced so that no excise tax is payable, but only if this reduction results in a more favorable after-tax position for such NEO.

*Termination upon expiration of the term*

If the term of an NEO's employment agreement expires without the Company offering to renew it on the same terms and conditions upon the expiration of the term, such NEO will be entitled to receive:

• continued payment of base salary for 24 months; and

• continued participation in our medical, dental and hospitalization coverage for 12 months on the same terms and conditions as immediately prior to the date of termination (i.e., at active employee rates).

*Release and Restrictive Covenants* 

All severance payments to our NEOs are subject to the execution and non-revocation of an effective release in our favor and the NEO's continued compliance with the restrictive covenants set forth in the employment agreement.

POTENTIAL PAYMENTS ON TERMINATION OR CHANGE IN CONTROL

*Definitions* 

For purposes of all of the employment agreements:

"cause" is generally defined as:

• conviction of, or plea of no contest to a felony (other than in connection with a traffic violation);

• the NEO's continued failure to substantially perform his or her material duties under the employment agreement;

• an act of fraud or gross or willful material misconduct;

• any act of workplace harassment which exposes the Company to risk of material civil or criminal legal damages and materially adversely affects the Company's business or reputation; or

• a material breach by the NEO of the restrictive covenants of his or her employment agreement.

"change in control" means:

• an acquisition of more than 50% of our voting securities (other than acquisitions from or by us);

• an acquisition of more than 30% of our voting securities in one or a series of related transactions during any 12-month period (other than acquisition from or by us);

• certain changes in a majority of the Board of Directors;

• a merger or consolidation of the Company other than a merger or consolidation in which the Company is the surviving entity (other than a recapitalization in which no person or entity acquires more than 50% of our voting securities); or

• a sale or disposition of at least 40% of the total gross fair market value of our assets, other than a sale or disposition of all or substantially all of our assets to a person or entity that owns more than 50% of our voting securities.

"disability" is generally defined as the NEO being unable to perform their material duties under the employment agreement due to illness, physical or mental disability or other similar incapacity that continues for 180 consecutive days or 240 days in any 24-month period.

"good reason" is generally defined as:

• any material diminution or material adverse change to the applicable NEO's title, duties or authorities;

• a reduction in the NEO's base salary or target bonus, except for a base salary reduction of up to 10% as part of across-the-board reductions in base salary for all senior executives;

• a material adverse change in the applicable NEO's reporting responsibilities or the assignment of duties substantially inconsistent with his or her position or status with the Company;

• a relocation of the NEO's primary place of employment to a location more than 25 miles further from his or her primary residence than the current location of the Company's offices;

• any material breach by the Company of the material provisions of the employment agreement or any other agreement with the Company or its affiliates;

• any material diminution in the aggregate value of employee benefits provided to the NEO on the effective date of the employment agreement; however, if such reduction occurs at any time other than within the two year period following a change in control, such NEO will not have good reason for across-the-board reductions in benefits applicable to all senior executives.

NEO EQUITY AWARD AGREEMENTS

NEO EQUITY AWARD AGREEMENTS

The equity award agreements governing the outstanding restricted stock units and stock appreciation rights held by the NEOs provide for certain accelerated vesting of the underlying award, as summarized below:

*Change in Control* 

For purposes of the 2021 Plan and the 2012 Plan and the applicable equity award agreements, a "change in control" generally has the same meaning as set forth in the employment agreements with the NEOs as described above.

With respect to all unvested restricted stock units and stock appreciation rights, if within 30 days prior or 24 months following the completion of a change in control or at any time prior to a change in control at the request of a prospective purchaser whose proposed purchase would constitute a change in control upon its completion, the participant's employment is terminated either without "cause" or by the participant for "good reason" (each as defined above for the NEOs), any such awards will become fully vested on the date of such termination of employment.

*Death or Disability* 

If a participant's employment is terminated due to death or disability, all awards will become fully vested. With respect to any performance-based restricted stock units, the number of units subject to such accelerated vesting will be counted at target.

For purposes of the 2021 Plan and the 2012 Plan and the applicable equity award agreements, a "disability" generally means the inability of a participant to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.

## CEO Pay Ratio

------

In accordance with the SEC rules, we are providing the ratio of the annual total compensation of our CEO, to the annual total compensation of our median employee.

For 2022, we used the same median employee that was identified in our 2021 proxy statement, as we believe there have been no significant changes in the employee population or compensation arrangements during 2022 that would significantly affect our CEO pay ratio calculation.

To identify our median employee for our 2021 disclosure, we determined our global employee population of approximately 10,093 employees (excluding our CEO, contract and leave of absence employees) as of December 31, 2021, which included 6,072 U.S. employees and 4,021 non-U.S. employees. We excluded all employees in Malaysia (267) and China (3) under the *de minimus* exception, as an aggregate number of employees (270) represents less than 5% of our total global employee population. After taking into account this *de minimis* exception, 9,823 employees, including 3,751 non-U.S. employees, were considered in identifying the median employee.

After determining our global employee population, we used annual taxable compensation as derived from our tax and/or payroll records, converted to U.S. dollars, as our consistently applied compensation measure. We believe that using taxable compensation encompasses all the principal methods of gathering compensation of our employees and provides a reasonable estimate of annual compensation for our employees. Furthermore, in identifying our median employee, we annualized base wages for employees who were not employed for the full 2021 fiscal year.

After identifying our median employee, we then calculated the annual total compensation for our median employee using the same methodology used for our CEO as set forth in the Summary Compensation Table of this Proxy Statement. Below is the calculation of our 2022 CEO pay ratio:

---

| | |
|:---|:---|
| &nbsp;&nbsp; CEO Total Annual Compensation | $7897415 |
| &nbsp;&nbsp; Median Employee Total Annual Compensation | $46318 |
| &nbsp;&nbsp; **CEO to Median Employee Compensation Ratio** | **171:1** |

---

Our CEO received a special one-time grant of performance-based restricted stock units on August 3, 2022 of $2,499,968. Excluding this one-time special grant, our CEO Pay Ratio for 2022 would be 117:1. We offer this information as additional consideration and point of reference only.

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

## Pay Versus Performance
As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K ("Item 402(v)"), the Company is providing the following information regarding the relationship between the executive "Compensation Actually Paid" as defined in Item 402(v)) ("CAP") by the Company and the financial performance of the Company over the applicable time period of the disclosure, calculated in a manner consistent with Item 402(v). For a more accurate description of our executive compensation program and the factors used by the Human Resources and Compensation Committee to determine pay for our NEOs, see the "Compensation Discussion and Analysis" section of this Proxy Statement. Accordingly, the following table sets forth the CAP for the Company's Principal Executive Officer ("PEO") and the average CAP for non-PEO NEOs and the Company's financial performance metrics for 2022, 2021 and 2020.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) This column represents the dollar amounts of the Stock Awards and Option Awards from the Summary Compensation Table for 2022, 2021 and 2020.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) This column represents the method for calculating the fair value of SARs and PRSUs as defined by Item 402(v). The fair value of each SAR was estimated as of the relevant valuation date in accordance with FASB ASC Topic 718 using the Black-Scholes option pricing model and the key input variables (assumptions) of that model as described in Note 12 to our financial statements for the fiscal year ended January 1, 2023 included in the Company's Annual Report on Form 10-K. The assumptions used were not materially changed from those described in Note 12 but were updated at each valuation date to reflect the then-current value of each variable. The fair value of PRSUs was estimated at each valuation date using: (i) the market price of the Company's Common Shares on the relevant valuation date, and (ii) an adjustment to reflect actual performance for any completed performance year and an assumption regarding attainment of the performance goals for the remaining performance period.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The dollar amounts reported in this column are the average of the amounts of total compensation reported for each non-PEO NEO for the covered years: Messrs. Tiejema, Ball, White and Paxton for 2022, Messrs. Tiejema, White, Lewis and Paxton for 2021, and Messrs. Hair, Tiejema, Lewis and White for 2020, collectively our non-PEO NEOs for each covered year as reported in the "Total" column of the "Summary Compensation Table" in this and prior years' Proxy Statements.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Total shareholder return as calculated based on a fixed investment of $100 in the Company's Common Shares measured from the market close on December 27, 2019 (the last trading day of our fiscal 2019) through and including the end of the first year for each year reported in the table.

&nbsp;&nbsp;&nbsp;&nbsp;(5) Total shareholder return as calculated based on a fixed investment of $100 in the S&P Composite 1500 Building Products Index, which is the peer group used for this Pay versus Performance analysis, measured from the market close on December 27, 2019 (the last trading day of our fiscal 2019) through and including the end of the first year for each year reported in the table.

&nbsp;&nbsp;&nbsp;&nbsp;(6) As reported in the Annual Report on Form 10-K for the fiscal year ended January 1, 2023, these amounts reflect "Net Income" of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;(7) For purposes of Item 402(v)(2)(iii), we have identified Adjusted EBITDA as our Company-Selected Measure. Although Adjusted EBITDA is one important financial performance measure, among others, that the Human Resources and Compensation Committee considers when making executive compensation decisions with the intent of aligning compensation with Company performance and has been selected as the primary performance metrics under the MIP by the Human Resources and Compensation Committee and does not use any one financial or other performance measure to specifically link executive CAP to Company performance.

PAY VERSUS PERFORMANCE RELATIONSHIP DESCRIPTION

The Human Resources and Compensation Committee strives to achieve its compensation philosophy and objectives by establishing an executive compensation program that links compensation to the financial and operating performance goals of the Company and is designed to align the interest of management with those of our Shareholders and to drive long-term Shareholder value.

Total Shareholder Return

As shown in the following graph, the CAP to our PEO and non-PEO NEOs was generally correlated to the Company's Total Shareholder Return ("TSR") over the three-year period. In 2021, the CAP to our PEO and non-PEO NEOs had a slight decline from the prior year as our Company's TSR and peer group TSR increased, and the CAP to our PEO and non-PEO NEOs for 2022 continued to decrease slightly and was more closely correlated with our Company's TSR and peer group TSR year-over-year change from 2021 to 2022. For fiscal years 2020,

Pay Versus Performance

PAY VERSUS PERFORMANCE RELATIONSHIP DESCRIPTION

2021 and 2022, the Human Resources and Compensation Committee did not select the Company's TSR, peer group TSR or Net Income as specific financial performance measures to align executive compensation and financial and operational performance. In 2022, the Human Resources and Compensation Committee, as described in more detail under "Elements of our Executive Compensation Program — Long Term Equity Incentive Awards—Performance-Vesting Restricted Stock Units" in the "Compensation Discussion and Analysis" section of this Proxy Statement, selected, as a component of our Long-Term Incentive Award, Net Sales and Return On Invested Capital as the most appropriate financial metrics to incentivize growth by encouraging management's focus on actions to improve the long-term financial health and performance of the Company. Additionally, our NEOs receive SARs as part of our executive compensation program which, although not directly tied to our TSR, are directly tied to the share price of our Common Shares as the SARs only retain value if the share price of our Common Shares increases above the exercise price and therefore further aligns our NEOs' interests with those of our Shareholders by providing a continuing financial incentive to maximize long-term Shareholder value.

![](g326829g38z01.jpg)

Net Income

As shown in the following graph, the CAP of our PEO and non-PEO NEOs did not highly correlate to the Net Income growth of the Company, as indicated by a slight decline in CAP over the 3-year period compared to significant growth in the Company's Net Income as reported.

Pay Versus Performance

PAY VERSUS PERFORMANCE RELATIONSHIP DESCRIPTION

Company Selected-Measure: Adjusted EBITDA

As shown in the following graph, the CAP of our PEO and non-PEO NEOs did not highly correlate to the Adjusted EBITDA growth of the Company. The Company selected Adjusted EBITDA as our Company-Selected Measure as Adjusted EBITDA is already a component of our executive compensation program as described in more detail under the "Elements of our Executive Compensation Program – Annual Cash Incentive Bonus" section of this Proxy Statement. The Human Resources and Compensation Committee has utilized Adjusted EBITDA as the primary performance measure for purposes of our MIP to focus our NEOs on growing total Company profitability. Human Resources and Compensation Committee believes that using Adjusted EBITDA as a key financial performance metric in our MIP is effective in driving total Company profitability and long-term Shareholder value.

![](g326829g00w24.jpg)

TABULAR LIST OF FINANCIAL PERFORMANCE MEASURES

In accordance with the requirements of Item 402(v)(6), we have identified an unranked list of the most important financial performance measures, which the Human Resources and Compensation Committee considered, among others, when making executive compensation decisions for performance year 2022. The use of each performance measure is further described in the "Compensation Discussion and Analysis" section of this and previous Proxy Statements within the sub-section titled "Elements of our Compensation Program."

• Adjusted EBITDA

• Adjusted EBITDA Margin

• Return on Invested Capital

• Net Sales

As noted above in this section, the Human Resources and Compensation Committee has not historically and does not currently evaluate CAP as calculated pursuant to Item 402(v)(2) as part of its executive compensation determinations; accordingly, the Human Resources and Compensation Committee does not actually use any financial or non-financial performance measures specifically to link NEO CAP to Company performance.

All information provided above under the "Pay Versus Performance" heading will not be deemed to be incorporated by reference in any filing of our Company under the Securities Act of 1933, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

## Proposal 2: Advisory Vote on Executive Compensation

------

In accordance with the requirements of Section 14A of the Exchange Act and the related rules of the SEC, our Shareholders are being asked to approve, in an advisory, non-binding vote, the compensation of our NEOs as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion.

In considering their vote, we urge Shareholders to review the information on our compensation policies and decisions regarding the NEOs presented in the Compensation Discussion and Analysis of this Proxy Statement, as well as the discussions regarding Human Resources and Compensation Committee described in the "Corporate Governance - Board and Committee Matters - Board Committees - Membership".

This advisory resolution, commonly referred to as a "say-on-pay" resolution, is non-binding. Although this resolution is non-binding, the Board and the Human Resources and Compensation Committee value the opinions of our Shareholders and will review and consider the voting results when making future compensation decisions for our NEOs. We currently intend to hold this vote annually. The next such vote will be held at the Company's 2024 annual general meeting.

We believe that our compensation components provide a reasonable balance of base compensation, cash incentive compensation and long-term equity-based incentive compensation that is closely aligned with the Company's overall performance. The Company aims to provide executive officers with a reasonable level of security through base salary and benefits, while rewarding them through cash and equity-based incentive compensation to achieve business objectives and create Shareholder value. We believe that each of our executive compensation components is integral to attracting, retaining and rewarding our qualified NEOs.

The text of the resolution in respect of Proposal No. 2 is as follows:

**RESOLVED**, that, the compensation paid to the Company's Named Executive Officers as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby approved.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

## Audit Committee Report

------

The Audit Committee operates pursuant to a charter that is reviewed annually by the Audit Committee. Additionally, a brief description of the primary responsibilities of the Audit Committee is included in "Corporate Governance; Board and Committee Matters - Board Committees; Membership - Audit Committee" of this Proxy Statement. Under the Audit Committee charter, management is responsible for the preparation, presentation and integrity of the Company's financial statements, the application of accounting and financial reporting principles and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The independent registered public accounting firm is responsible for auditing the Company's financial statements and expressing an opinion as to their conformity with U.S. generally accepted accounting principles. In addition, the independent registered public accounting firm is responsible for auditing and expressing an opinion on the Company's internal controls over financial reporting.

In the performance of its oversight function, the Audit Committee reviewed and discussed the audited financial statements of the Company with management and with Ernst & Young LLP ("**EY**"), the Company's independent registered public accounting firm. The Audit Committee also discussed with EY the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("**PCAOB**") and the SEC. In addition, the Audit Committee received the written disclosures and the letter from EY required by applicable requirements of the PCAOB regarding EY's communications with the Audit Committee concerning independence, and discussed with the independent registered public accounting firm their independence.

Based upon the review and discussions described in the preceding paragraph, the Audit Committee recommended to the Board that the audited financial statements of the Company be included in the Annual Report on Form 10-K for the year ended January 1, 2023 filed with the SEC.

Submitted by the Audit Committee of the Company's Board.

## Proposal 3: Appointment of Independent Registered Public Accounting Firm

------

Our consolidated financial statements for the fiscal year ended January 1, 2023 have been audited by Ernst & Young LLP, our independent registered public accounting firm. On the recommendation of the Audit Committee, the Board recommends the appointment of EY as the independent registered public accounting firm to serve until the next annual general meeting of Shareholders and to authorize the Board to fix its remuneration for such term.

A representative of EY is expected to be present at the Annual Meeting in order to respond to appropriate questions and to make any other statement deemed appropriate.

SERVICE FEES PAID TO THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

EY began acting as our independent auditors with respect to the audit of our financial statements beginning with the 2017 fiscal year. The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the independent registered public accounting firm retained to audit our financial statements. The Audit Committee is responsible for the audit fee negotiations associated with the appointment of EY as our independent registered public accounting firm for the fiscal year ending January 1, 2023.

The fees charged by EY for professional services rendered in connection with all audit and non-audit related matters for fiscal years ended January 1, 2023 and January 2, 2022 were as follows:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp; Type of Fees | 2022 ($) | 2021 ($) |
| &nbsp;&nbsp; Audit-Fees | 3261298 | 3141592 |
| &nbsp;&nbsp; Audit-Related Fees | 580366 | 17980 |
| &nbsp;&nbsp; Tax Fees | 479814 | 375802 |
| &nbsp;&nbsp; All Other Fees |  |  |
| &nbsp;&nbsp; **Totals** | 4321478 | 3535374 |

INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS-FEE INFORMATION

Audit Fees

Fees for audit services in 2022 and in 2021 consisted of (a) audits of the Company's annual consolidated financial statements, (b) reviews of the Company's quarterly condensed consolidated financial statements included in our Quarterly Reports on Form 10-Q, and (c) annual stand-alone statutory audits. Fees for audit services also included services in connection with SEC registrations and other offering or filings.

Audit-Related Fees

Audit-related services principally include assurance and related services by the independent auditors that are reasonably related to the performance of the audit or review of our financial statements, or other filings that are not captured under "Audit Fees" above.

Tax Fees

Tax services in 2022 and 2021 consisted of professional services rendered by EY for tax return preparation, tax compliance, and tax advice.

All Other Fees

There were no other fees in 2022 or 2021.

The Audit Committee considered whether EY's provision of the above non-audit services is compatible with maintaining such firm's independence and satisfied itself as to EY's independence.

POLICY ON AUDIT COMMITTEE PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT SERVICES OF INDEPENDENT AUDITORS

POLICY ON AUDIT COMMITTEE PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT SERVICES OF INDEPENDENT AUDITORS

Consistent with the SEC policies regarding auditor independence and the Audit Committee charter, the Audit Committee has responsibility for appointing, setting compensation and reviewing the performance of the independent auditors. In exercising this responsibility, the Audit Committee has established pre-approval policies with respect to audit and permissible non-audit services to be provided by the independent auditors and the related fees. Pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and is generally subject to a specific limit above which separate pre-approval is required. Management is required to periodically report to the Audit Committee regarding the extent of services provided by the independent auditors in accordance with this pre-approval, and the fees for the services performed to date. To ensure prompt handling of unexpected matters, the Audit Committee has delegated to the Chairman of the Audit Committee the authority to pre-approve permissible non-audit services and fees. Any action taken in this regard is reported to the Audit Committee at the next scheduled Audit Committee meeting.

The Board requests that Shareholders approve the appointment of EY and authorize the Board to fix EY's remuneration for such term. This appointment will be dependent on no other independent registered public accounting firm being put forward at the Annual Meeting and receiving more "FOR" votes than EY. If the approval of this appointment (or the appointment of an alternate registered public accounting firm) does not occur, then the BCBCA provides that the current auditors, EY, will continue to act for the Company until such time as the Shareholders approve successor auditors.

THE BOARD RECOMMENDS A VOTE "FOR" THE APPOINTMENT OF ERNST & YOUNG LLP AS AUDITORS TO SERVE UNTIL THE NEXT ANNUAL GENERAL MEETING OF THE COMPANY AND THE AUTHORIZATION OF THE BOARD OF DIRECTORS TO FIX THE AUDITOR'S REMUNERATION.

## Shareholder Proposals for 2024 Annual General Meeting

------

It is currently contemplated that our 2024 annual general meeting of Shareholders will take place on May 9, 2024. In accordance with the rules established by the SEC, any Shareholder proposal submitted pursuant to Rule 14a-8 to be included in the proxy statement and form of proxy for that meeting must be received by us by November 30, 2023. In order for your proposal to be included in the proxy statement and form of proxy, the proposal must comply with the requirements established by the SEC, the BCBCA and our Articles. If you would like to submit a Shareholder proposal to be included in our proxy materials, you should send your proposal to our Corporate Secretary at the Company's principal executive office located at 2771 Rutherford Road, Concord, Ontario, Canada L4K 2N6.

Our Articles require the timely notice of certain information to be provided by any Shareholder who proposes director nominations for consideration at a Shareholders' meeting. Failure to deliver a proposal in accordance with these requirements may result in it not being deemed timely received. To be timely, notice of a director nomination must be received by our Corporate Secretary at the registered office or the principal executive office of the Company no less than 30 days nor more than 65 days before the date of the 2024 annual general meeting of Shareholders, subject to certain exceptions as described in our Articles. As such, assuming the 2024 annual general meeting of Shareholders is held on May 9, 2024, any such director nominations submitted for consideration at such meeting must be received no earlier than March 5, 2024 and no later than April 9, 2024 in order for it to be deemed timely received.

In addition to satisfying the foregoing requirements under our Articles, to comply with the universal proxy rules, Shareholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 12, 2024.

Pursuant to the BCBCA, a registered or beneficial Shareholder who holds no less than 1/100 of the issued Common Shares of the Company and provided those shares have a fair market value of no less than Cdn$2,000 (approximately US$1,568.18 as of March 20, 2023, the record date for the Annual Meeting), may submit a proposal (other than a proposal to appoint a director as outlined above) for consideration at an annual general meeting of the Company (a "BCBCA Proposal"). In order to be valid, the proposal must meet several technical requirements, including a requirement that the proposal be for a valid purpose relating to the business and affairs of the Company, and that the form of proposal is delivered to the registered office of the Company no less than three months prior to the anniversary of the last annual general meeting of the Company. If a Shareholder submits a BCBCA Proposal for consideration at the 2024 annual general meeting outside the processes of Rule 14a-8 of the Exchange Act, and that submission occurs after the close of business on February 11, 2024, assuming the Meeting is held on May 9, 2024, then the Company would not need to include such proposal with the notice of meeting and other meeting materials for the 2024 annual general meeting and, in accordance with the BCBCA and the Articles of the Company, could prohibit that matter from being considered at that meeting.

## Householding of Proxy Materials

------

SEC rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and notices with respect to two or more shareholders sharing the same address by delivering a single proxy statement or a single notice addressed to those shareholders. This process, which is commonly referred to as "householding", provides cost savings for companies. Some brokers household proxy materials, delivering a single proxy statement or notice to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate Proxy Statement or notice, or if you are receiving duplicate copies of these materials and wish to have householding apply, please notify your broker. You can also request prompt delivery of a paper copy of this Proxy Statement and Annual Report on Form 10-K ending January 1, 2023, by contacting Masonite Investor Relations, by mail at 1242 East 5th Avenue, Tampa, Florida 33605, by telephone at (813) 877-2726, or by email at investorrelations@masonite.com.
