~~Additionally, some stockholders did not require a meeting as they either indicated their support for our governance practices or did not have concerns at this time.~~

The Nominating and Governance Committee of the Board (the “Nominating and Corporate Governance Committee”) and the Board’s Compensation Committee (the “Compensation Committee”) reviewed feedback from our stockholders. Through these conversations, some of our stockholders have suggested that we consider substantive changes or additional disclosures. The feedback we received covered a number of key issues including:

•

~~Our classified board structure;~~

•

~~The supermajority voting requirement to amend our Charter and By-laws (each as defined below);~~

•

~~The inclusion of performance-based awards in executive compensation; and~~

•

~~Enhanced transparency and disclosure regarding director skills and qualifications and CEO succession.~~

Below are the primary changes we have made since last year as a result of these discussions as well as our ongoing review of our corporate governance practices as we transition away from being a controlled company:

•

Proactively approved, subject to stockholder approval, amendments to the Company’s Second Amended and Restated Certificate of Incorporation (“Charter”) and the Company’s Second Amended and Restated By-laws (the “By-laws”) to eliminate supermajority voting requirements as described in Proposal 2;

•

~~Incorporated performance-based awards into the long-term equity incentive compensation of our named executive officers (“NEOs”) for 2019;~~

•

~~Provided additional disclosure in our Proxy Statement regarding the skills, experience and qualifications of our directors; and~~

In addition to input on current corporate governance topics, we invite dialogue about any other topics or trends our stockholders may wish to discuss.

The Board has also established a process ~~for~~by which stockholders tomay communicate with its members.

~~Compensation Highlights~~Governance Highlights

Since our IPO, we have undertaken an extensive board refreshment process to transition to a board with the independence, skills and qualifications reflective of our business.

Compensation Highlights

Our executive compensation program is designed to encourage high performance and results that will create value for our stockholders while avoiding unnecessary risks. We structure compensation to pay for performance,

TABLE OF CONTENTS

with clear and measurable goals and aggressive yet achievable performance targets. To create a ~~“pay~~pay for ~~performance”~~performance environment, compensation is weighted toward at-risk compensation. Our long-term equity incentive program (“LTIP”), which consisted of approximately ~~75%~~33% stock options, 33% performance stock units (“PSUs”) and ~~25%~~33% restricted stock units (“RSUs”) for the ~~fiscal year ended December 30, 2018 (the “2018~~2023 Fiscal ~~Year”),~~Year, is designed to serve stockholders’ best interests in our sustained long-term performance by including ~~extended~~performance-based awards, multi-year vesting schedules and ~~significant~~meaningful stock ownership requirements. The value of the option grants depends on our future performance, as the options carry a strike price based on the trading price of our stock on the date of grant and, under our long-term equity incentive plan, underwater options are prohibited from being repriced without stockholder approval. We believe our NEOs are compensated in a manner consistent with our strategy, competitive practice, sound compensation governance principles and alignment with stockholder interests.

In order to further ensure that our executive compensation aligns with pay for performance and facilitates long-term stockholder value creation, in February 2019, the Compensation Committee approved performance-based awards (“PSUs”) as part of our NEOs’ long term-equity incentive compensation. For the fiscal year ending December 29, 2019 (the “2019 Fiscal Year”), PSUs will represent 25% of our NEOs’ long-term incentive compensation, with stock options and RSUs representing the remaining 50% and 25%, respectively. The PSUs, which reflect a target number of shares that may be issued to the award recipient at the end of a three-year award cycle based on the achievement of rigorous performance targets established at the time of grant, utilize a three-year relative pre-tax earnings growth ~~performance~~ metric ~~closely linked to~~highly correlated with stock price performance, with the actual number of shares ~~granted~~earned subject to modification based on a three-year average absolute return on invested capital ~~metric. PSUs are~~(“ROIC”) modifier. PSU payout is capped at 200% of ~~“target.”~~

~~For~~target. The value of the ~~2018~~option grants depends on our future stock price performance, as the options carry a strike price based on the trading price of our stock on the date of grant. In addition, under our LTIP, underwater options are prohibited from being repriced or cashed out without stockholder approval. We strive to compensate our named executive officers (“NEOs”) in a manner consistent with our strategy, competitive market practices, sound compensation governance principles and in alignment with stockholder interests. To that end, in connection with its annual review of our executive compensation program, including input from the Human Resources and Compensation Committee’s independent consultant, Frederic W. Cook & Co. (“FW Cook”), and feedback received from our stockholders during the 2023 Fiscal Year, ~~base salaries~~in February 2024, our Human Resources and Compensation Committee approved an award mix for our NEOs under the LTIP consisting of 50% PSUs and 50% RSUs for the 2024 Fiscal Year. We believe this update to the award mix under our LTIP further demonstrates our commitment to designing an executive compensation program that encourages high performance and results that will create value for us and our stockholders while avoiding unnecessary risks. We also believe this updated LTIP design evidences our responsiveness to stockholder feedback to enhance the alignment of our executives’ interests with our stockholder interests and allow our executives to share in our stockholders’ success.

For the 2023 Fiscal Year, the aggregate base salaries of our NEOs were ~~in aggregate, between~~approximated to the 2550th ~~and 50~~th percentile of our peer group. The target for the Adjusted EBITDA metric under our annual incentive program was ~~$191.0~~$462-464 million, ~~an increase of approximately 22% compared to the~~in line with our results for the fiscal year ended ~~December 31, 2017~~January 1, 2023 (the ~~“2017~~“2022 Fiscal Year”). Maximum payouts under the Adjusted EBITDA metric are ~~now~~ capped at 250% of target, with the remaining components each capped at 150% of target. ~~Notwithstanding our strong financial results that delivered double-digit growth,~~The short-term annual cash incentive payouts for each of our NEOs on the Adjusted EBITDA component (constituting 70% of the performance metric weighting for each of our NEOs) ~~was only 54%~~were 58% of target for the ~~2018~~2023 Fiscal Year as our Adjusted EBITDA exceeded the threshold performance level but fell short of ~~plan.~~target performance.

Supporting Associates

We believe our employees, referred to by us as our “associates,”are our greatest asset. The safety, health and wellness of our associates and their families is our top priority. The support that we offer to our associates is an important part of our Vision to be a great place to work and the employer of choice in the green industry.

Diversity and Inclusion

We believe in the power of teamwork and in creating a great place to work for all our associates, no matter their race, age, gender, sexual orientation or military status. At SiteOne, a culture in which all our associates are respected and valued is critical. Our diversity and inclusion efforts focus on creating a work environment that is respectful and supportive of each of our associates and which places the team first. Our initiatives include the following:

•

Metrics intended to increase the Company’s diversity in certain field and field support associates’ short-term incentive bonus plans.

•

Associate Resource Groups (“ARGs”), which are voluntary, associate-led groups tied to an aspect of diversity. Membership in each ARG is open to all SiteOne associates and diverse representation is encouraged. ARGs support business objectives, create diversity awareness and offer an avenue of development for associates. Our ARGs include the following:

◦

Black Resource Inclusion and Diversity Group for Excellence — BR1DGE provides a network for Black associates to be connected and supported, and to process and discuss life experiences in a safe space.

◦

INSP1RE — INSP1RE fosters an inclusive culture with a focus on our extended Asian community — South Asia, South-East Asia, East Asia, Asian Pacific Islander, Asian American and beyond, creating a platform for our teams to feel inspired, empowered, celebrated and supported.

◦

UN1DOS — UN1DOS attracts and retains engaged and diverse associates while enhancing SiteOne’s understanding of and relationships with Hispanic communities and customers.

◦

VETS1 — VETS1 fosters an environment of diverse and engaged associates while developing SiteOne’s understanding of and relationships with veteran associates, customers and communities.

◦

Women in the Green Growing — W1GG promotes an environment of diverse and engaged associates while advocating female growth within SiteOne and the green industry.

The creation of a Diversity & Inclusion Council during 2020 that consists of ARG leaders, select operational and functional leaders, our Executive Vice President of Human Resources and our Chief Executive Officer. The Diversity & Inclusion Council assists executive leadership in the creation and execution of the Company’s inclusion strategy, including key action items and milestones.

•

Increasing our Spanish-speaking capabilities in our branches to better meet the needs of our growing customer base, with the goal to employ at least one Spanish-speaking associate in each branch in the United States.

•

Partnering with Sigma Alpha, a professional agricultural sorority, to develop a pipeline of female talent. For the past five years, female associates of SiteOne have mentored over 100 students across the country, leading to hiring Sigma Alpha sisters in both our internship and entry level roles in both field operations and field support.

•

Other diversity and inclusion partnerships and initiatives, including Minorities in Agriculture, Natural Resources, and Related Sciences (“MANRRS”) sponsorship, high school recruiting programs, particularly with JR MANRRS, Historically Black Colleges and Universities and Hispanic Serving Institutions recruiting strategies and veteran programs like Hiring Our Heroes, which has resulted in 100% conversion from fellowships to full-time hires.

Associate Engagement

We administer associate engagement surveys to determine how we are doing in our mission to be the employer of choice in the green industry. We review the survey results with all of our associates and seek their involvement in developing and executing action plans to continue our workplace improvements. We monitor associate satisfaction and aim to strengthen our pipeline of top talent by conducting talent reviews and succession planning for all critical roles in the organization. We identify, communicate, and utilize career development paths for key roles. This includes not only an upward path for associates, but exposure to parallel roles across the organization.

We engage an independent third party to implement our survey and compare our results against industry norms. For our 2023 engagement survey, we again experienced high levels of participation in our associate engagement survey with approximately 76% of our associates participating:

•

Overall favorable score of 83 (out of 100), compared to a score of 85 in 2021 and 81 in 2019 and two points above “U.S. Retail Norm” (average score of all other U.S. companies in similar industries who utilized the same third party for their surveys).

•

“Associate promoter score” of 88 (out of 100), which reflects if our associates consider SiteOne a “great place to work,” compared to a score of 87 in 2021 and 89 in 2019.

•

At or above the majority of industry benchmarks in the 15 categories that we measure, including a 94 (out of 100) score in safety, 91 (out of 100) score in empowerment and 87 (out of 100) score in strategy and direction.

We continue to focus on leveraging this feedback to identify opportunities for enhancing our associate experience.

Associate Support Programs

We offer a competitive benefits package with the goal of enabling our associates to get the most out of work and life. Among our benefits, we offer a paid military leave benefit that provides additional resources to our full-time associates as they continue to serve our country. In addition, given the difficulties our associates experienced during the COVID-19 pandemic, we adjusted our PTO carry-over rule for 2021 and 2022 to allow associates to carry over additional hours into the following year. We also offer a paid parental leave benefit for our full-time associates to help parents during the early days of parenthood. The parental leave benefit provides time away from work within the first year of the birth or adoption of a child with 100% of base pay.

In 2022, we launched SiteOne CARES, a grant assistance program designed to help our associates cope with unexpected financial challenges arising from personal hardships. We made an initial contribution of $75,000 to the SiteOne Cares fund and matched 100% of every associate contribution up to the first $25,000 associate

donations. As of December 31, 2023, we reached over $40,000 in associate donations to the fund and assisted 34 associates in need. In 2024, we made another contribution of $75,000 to the SiteOne Cares fund, with a commitment to match the next $25,000 in associate donations.

In 2022, we also created a new bonus program for our hourly associates. During 2023 and 2022, approximately 2,340 and 2,750 associates, respectively, received the bonus with payments totaling approximately $1.4 million and $2.2 million, respectively. This program made all of our previously ineligible associates eligible to receive a bonus. We continue to review our compensation and benefits program to ensure we offer a competitive total rewards package.

As a stockholder, you are invited to attend the Annual Meeting and are requested to vote on the items of business described in this Proxy Statement. This Proxy Statement includes information that we are required to provide to you under U.S. Securities and Exchange Commission (“SEC”) rules and is designed to provide you with information relevant to the voting of your shares at the Annual Meeting. The proxy materials include this Proxy Statement and our Annual Report for the 2018 Fiscal Year, and have been made available to you by either mail or Notice (as defined below).

~~All stockholders and beneficial owners may access the proxy materials at~~ ~~www.proxyvote.com. In addition, this Proxy Statement and our Annual Report are available on our investor relations website located at~~ ~~http://investors.siteone.com/sec-filings~~.

~~What is Notice and Access and why did we elect to use it?~~

As permitted by the SEC, Notice and Access provides companies with the ability to make proxy materials available to stockholders electronically via the Internet. We have elected to provide our stockholders with a Notice of Internet Availability of Proxy Materials (“Notice”) instead of mailing a full set of printed proxy materials in the mail. The Notice is a document that provides instructions regarding how to:

				~~View our proxy materials on the internet~~
				~~View your shares~~
				~~Request printed copies of these materials, including the proxy card or voting instruction card~~

On or about [ ], 2019, we began mailing the Notice to beneficial owners and posted our proxy materials on the website referenced in the Notice. As more fully described in the Notice, stockholders who received the Notice may choose to access our proxy materials on the website referenced in the Notice or may request a printed set of our proxy materials. If you choose to receive future proxy materials by e-mail, you will receive an e-mail next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by e-mail will remain in effect until you terminate it.

We have chosen to provide electronic access to our proxy materials because we are committed to environmental sustainability and responsibility. Utilizing Notice and Access will save us the cost of printing and mailing documents to you and will reduce the impact of our annual meetings on the environment.

~~Who is entitled to vote at the Annual Meeting?~~

The record date for stockholders entitled to notice of, and to vote at, the Annual Meeting is March 18, 2019. At the close of business on that date, we had 40,978,541 shares of common stock issued and outstanding and entitled to be voted at the Annual Meeting held by two stockholders of record. We have many more beneficial stockholders who hold shares through a broker, bank or other nominee. Each outstanding share of common stock is entitled to one vote. A list of stockholders entitled to vote at the Annual Meeting will be available in electronic form at the Annual Meeting and will be accessible in electronic form for ten days prior to the Annual Meeting at our headquarters, 300 Colonial Center Parkway, Suite 600, Roswell, Georgia 30076, between the hours of 9:00 a.m. and 5:00 p.m., Eastern Time.

By granting a proxy, you authorize the persons named as proxies to represent you and vote your shares at the Annual Meeting. Those persons will also be authorized to vote your shares to adjourn the Annual Meeting from time to time and to vote your shares at any adjournments or postponements of the Annual Meeting.

~~TABLE OF CONTENTS~~

~~Registered Stockholders.~~ If your shares are registered directly in your name with our transfer agent, American Stock Transfer & Trust Company (“AST”), you are considered the stockholder of record with respect to those shares and the proxy materials were provided to you directly by us. As a stockholder of record, you have the right to grant your voting proxy directly to the individuals named as proxies on the proxy card in one of the manners listed on the proxy card or to vote in person at the Annual Meeting.

~~Beneficial Stockholders.~~ If your shares are held in a stock brokerage account or by a broker, bank or other nominee, you are considered the beneficial owner of shares held in “street name” and the proxy materials were forwarded to you by your broker, bank or other nominee, who is considered, with respect to those shares, to be the stockholder of record. As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares using the methods prescribed by your broker, bank or other nominee on the voting instruction card you received with the proxy materials. Like stockholders of record, beneficial owners are invited to attend the Annual Meeting. However, because you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you follow your broker’s, bank’s or other nominee’s procedures for obtaining a legal proxy from it, as the stockholder of record.

~~What items of business will be voted on at the Annual Meeting?~~

~~The items of business scheduled to be voted on at the Annual Meeting are:~~

	~~Other Proposals:~~			At the discretion of Doug Black and Briley Brisendine, the persons designated as proxies for the Annual Meeting, either “FOR”, “AGAINST” or “ABSTAIN” with regard to any other business that may properly come before the Annual Meeting.

As of the date hereof, the Board is not aware of any other business to be transacted at the Annual Meeting.

With regard to Proposals 2, 3 and 4 stockholders may vote “FOR” or “AGAINST” each proposal or may “ABSTAIN” from voting with regard to each proposal. Because a plurality vote is required for the election of directors, which means that the nominees receiving the highest number of “FOR” votes will be elected, withholding authority to vote with respect to one or more nominees for director will not affect the outcome of the election of directors in Proposal 1.

~~Can I vote in person at the Annual Meeting?~~

For stockholders with shares registered directly in their names with AST, our transfer agent, you may vote your shares in person at the Annual Meeting. For stockholders with shares registered in the name of a broker, bank or other nominee, you will need to obtain a legal proxy from the broker, bank or other nominee that holds your shares before you can vote your shares in person at the Annual Meeting. Written ballots will be passed out to anyone who wants to vote at the Annual Meeting. Even if you plan to attend the Annual Meeting, we encourage you to vote by proxy in advance. If you vote by Internet or by telephone, you do not need to return your proxy card. Voting in advance will not limit your right to vote at the Annual Meeting if you decide to attend in person.

~~What happens if the Annual Meeting is postponed or adjourned?~~

Unless a new record date is fixed, your proxy will still be good and may be voted at the postponed or adjourned Annual Meeting. You will still be able to change or revoke your proxy at any time until it is voted.

~~How do I vote by proxy?~~

~~There are three ways to vote by proxy:~~

				~~Over the Internet by following the instructions provided in the Notice;~~
				If you requested to receive printed proxy materials, by using the toll-free telephone number listed on the proxy card enclosed therein (specific directions for using the telephone voting system are included on the proxy card); or
				~~If you requested to receive printed proxy materials, by marking, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided.~~

If your shares are held in the name of a broker, bank or other holder of record, you will receive instructions from the holder of record. You must follow the instructions of the holder of record in order for your shares to be voted. If you vote by telephone or by the Internet, you do not need to send in a proxy card or voting instruction form. The deadline for telephone and Internet voting is 11:59 p.m., Eastern Time, on May 14, 2019.

~~The giving of a proxy will not affect your right to vote in person should you decide to attend the Annual Meeting.~~

~~How will my proxy be voted?~~

Proxies are being solicited on behalf of the Board for use at the Annual Meeting. All valid proxies that are not revoked will be voted as specified by the stockholders. In the absence of instructions, the shares of the common stock represented by valid proxies will be voted “FOR” the election of the persons named in this Proxy Statement as nominees for director of the Company, “FOR” the management proposal to amend and restate our Charter to eliminate supermajority voting requirements and other obsolete provisions, “FOR” the proposal regarding the advisory vote approving executive compensation and “FOR” the ratification of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the 2019 Fiscal Year.

~~How do I change or revoke my proxy?~~

Any person submitting a proxy has the power to revoke it prior to the Annual Meeting or at the Annual Meeting prior to the vote pursuant to the proxy. A proxy may be revoked by a writing delivered to us stating that the proxy is revoked, by a subsequent proxy that is signed by the person who signed the earlier proxy and is delivered before or at the Annual Meeting, by voting again on a later date on the Internet or by telephone (only your latest Internet or telephone proxy submitted prior to the Annual Meeting will be counted) or by attendance at the Annual Meeting and voting in person. Please note, however, that if a stockholder’s shares are held of record by a broker, bank, trustee or other nominee and that stockholder wishes to vote at the Annual Meeting, the stockholder must bring a legal proxy to the Annual Meeting.

~~TABLE OF CONTENTS~~

~~Who will count and certify the votes?~~

~~Representatives of Broadridge Financial Solutions, Inc. (“Broadridge”) and our corporate secretary will count the votes and certify the election results.~~

~~When and where will I be able to find the voting results?~~

You can find the official results of the voting at the Annual Meeting in our Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If the official results are not available at that time, we will provide preliminary voting results in the Form 8-K and will provide the final results in an amendment as soon as they become available.

~~Who pays for the cost of proxy preparation and solicitation?~~

The accompanying proxy is solicited by the Board. We have engaged Broadridge to assist us in the distribution of proxy materials and to provide voting and tabulation services for the Annual Meeting for an estimated cost of $60,000, plus expenses. All costs of the solicitation of proxies will be borne by us. We pay for the cost of proxy preparation and solicitation, including the reasonable charges and expenses of brokerage firms, banks, trusts or nominees for forwarding proxy materials to street name holders. We are soliciting proxies primarily by mail. In addition, our directors, officers and employees may solicit proxies by telephone or other means of communication personally. Our directors, officers and employees will receive no additional compensation for these services other than their regular compensation.

TABLE OF CONTENTS

~~PROPOSAL 2: Charter amendment to EliminatE Supermajority Voting Requirement~~

~~Introduction~~

After careful consideration and following engagement with, and feedback from, stockholders beneficially owning over 67% of our outstanding stock, the Board has unanimously determined that it would be advisable and in the best interests of the Company to amend and restate our Charter in the form attached hereto as Appendix B (the “Third Amended and Restated Certificate of Incorporation”). The Third Amended and Restated Certificate of Incorporation incorporates amendments to remove supermajority voting thresholds and other obsolete provisions relating to the prior equity ownership of our former equity sponsors, as described below (the “Proposed Amendments”). The Board is now recommending that stockholders adopt this Third Amended and Restated Certificate of Incorporation.

~~Current Standard~~

~~Currently, our Charter provides that certain amendments to our Charter require the affirmative vote of shares representing no less than two-thirds (66~~2∕3%) of our outstanding shares of common stock that are entitled to vote at any annual or special meeting of stockholders, and that stockholders may amend our By-laws with the affirmative vote of shares representing no less than two-thirds (662∕3~~%) of our outstanding shares of common stock that are entitled to vote at any annual or special meeting of stockholders. We refer to these standards as the “Supermajority Voting Requirements.”~~

~~Rationale for Proposed Amendments~~

The Board is committed to good corporate governance. As we have transitioned the Company from a controlled company to an independent company following the exit of our former equity sponsors, the Board believes that stockholders should have the ability to make changes to our Charter and By-laws with majority support, subject to applicable laws. The Board recognizes that elimination of the Supermajority Voting Requirements is consistent with generally held views of good corporate governance, and also considered the fact that many other public companies have transitioned away from supermajority voting provisions several years after going public.

~~In view of the considerations described above, the Board has unanimously determined to eliminate the Supermajority Voting Requirements as proposed.~~

~~Proposed Amendments~~

The Board has adopted and declared advisable, and recommends that stockholders adopt, the Proposed Amendments. If the Proposed Amendments are adopted, future stockholder-approved amendments to our By-laws, and certain amendments to our Charter, will require only the affirmative vote of a majority of our outstanding shares of common stock entitled to vote thereon.

The text of the Proposed Amendments is reflected in the Third Amended and Restated Certificate of Incorporation set forth in Appendix B to this Proxy Statement, with deletions indicated by strike throughs and additions indicated by underlining. In addition to eliminating the Supermajority Voting Requirements, the Proposed Amendments would also delete certain obsolete provisions relating to the prior equity ownership of our former equity sponsors.

If the Company’s stockholders adopt the Proposed Amendments, they will become effective upon the filing of the Third Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, which the Company plans to do promptly after the Annual Meeting. If the Company’s stockholders do not adopt the Proposed Amendments, the Supermajority Voting Requirements will remain.

The Board has adopted conforming amendments to the Company’s By-laws that will become effective upon our filing of the Third Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware.

CORPORATE GOVERNANCE

~~TABLE OF CONTENTS~~

~~Vote Required~~

~~The affirmative vote of the holders of two-thirds (66~~2∕3~~%) of the outstanding shares of common stock then entitled to vote at the Annual Meeting is required to adopt this proposal pursuant to our Charter as currently in effect.~~

~~RECOMMENDATION OF THE BOARD~~

~~The Board unanimously recommends that you vote “FOR” approval of the management proposal to amend and restate our charter to eliminate supermajority voting.~~

~~TABLE OF CONTENTS~~

~~Corporate Governance~~

The Board is committed to strong corporate governance. ~~Strong~~We believe strong corporate governance promotes the long-term interests of stockholders, strengthens board and management accountability and helps build public trust in our Company. The Board and its committees have adopted policies and processes that foster effective board oversight of critical matters such as strategy, risk management, including cybersecurity, financial and other controls, ~~environmental, social~~human capital and ~~governance~~sustainability considerations, compliance and management succession planning. The Board reviews our major governance documents, policies and processes regularly in the context of current corporate governance trends, regulatory changes and recognized best practices, taking into consideration the perspectives of our stockholders. Through our website, www.siteone.com,, our stockholders have access to key corporate governance documents such as our Corporate Governance Guidelines, Business Code of Conduct and Ethics, Financial Code of Ethics, Board of Directors Communication Policy, ~~and~~ charters of each committee of the ~~Board.~~Board and our annual IMPACT Report.

Based on feedback from stockholders over the course of the last year, at this year’s Annual Meeting we are seeking stockholder approval to remove the supermajority voting requirements from our Charter as described in Proposal 2. The Board has adopted conforming amendments to our By-laws that will become effective as described in Proposal 2 if these amendments to our Charter are approved by stockholders at the Annual Meeting. The Board believes that implementing a majority voting standard to amend our Charter and By-laws enhances the ability of our stockholders to influence our governance structure and is consistent with principles of strong corporate governance.

The following sections provide an overview of our corporate governance structure, policies and processes, including key aspects of the Board operations.

~~Board Structure~~Board Structure

The Board currently consists of ~~six~~seven directors and, upon the election of Ms. ~~Drake~~Sansone to the Board by stockholders at the Annual Meeting, will ~~increase~~be increased to ~~seven.~~consist of eight directors. Our Charter provides for a classified board of directors, with members of each class serving staggered three-year terms. At each annual meeting of stockholders, the successors of the directors whose terms expire at that meeting are elected to hold office for a term expiring at the annual meeting held in the third year following the year of their election. We currently have two directors in each of Classes I and II ~~and III, with~~(with an additional director, Ms. Sansone, nominated to serve in Class II), and three directors in Class III. The terms of the directors in Classes ~~I, II~~III and ~~III~~I expire at the annual meetings in ~~2020, 2021~~2025 and ~~2019,~~2026, respectively. Our stockholders are being asked to elect our Class II directors to serve for a three-year term expiring at the 2027 Annual Meeting of Stockholders. We believe that our classified board structure provides protection against opportunistic attempts to control or influence the Company, including those that advance short-term agendas which could deprive our stockholders of ~~value or advance short-term agendas.~~long-term value. During our stockholder outreach ~~program~~programs conducted in each of the ~~fall of 2018, we learned that~~last six years, our ~~investors~~stockholders have generally ~~have a positive or constructive view of~~found our classified board structure to be acceptable. Accordingly, while we do not intend to maintain a classified board structure in perpetuity, we believe our classified board structure remains the appropriate structure at this point in ~~time. Of~~time due to the ~~stockholders we engaged with, investors representing less than 8% of our outstanding shares opposed our classified board structure.~~specific circumstances described above.

The ~~number of members~~size of the Board is fixed by resolution adopted from time to time by the Board, but in no event may be less than one. Any vacancies or newly created directorships may be filled only by the affirmative vote of a majority of directors then in office, even if less than a quorum, or by a sole remaining director. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. A director elected to fill a vacancy or a newly created directorship shall hold office until the annual meeting at which his or her term expires and until his or her successor has been duly elected and qualified, or until his or her earlier death, resignation or removal from office.

~~Director Qualifications~~Director Qualifications and ~~Selection~~ Selection of ~~Nominees~~ Nominees

Our Corporate Governance Guidelines provide that the Nominating and Corporate Governance Committee will identify and recommend director nominees to the Board, including candidates to fill any vacancies that may occur on the Board. When evaluating director candidates, the Nominating and Corporate Governance Committee considers, in view of the needs of the Board at the time, factors such as business and professional experience, reputation for integrity, judgment, diversity, age, skills, background and demonstrated commitment to full participation on the Board and its committees. When current Board

The Board seeks members from diverse backgrounds who combine a broad spectrum of experience and expertise relevant to our business with a reputation for integrity. The Board believes that a variety of viewpoints contribute to a more effective decision-making process. While the Nominating and Corporate Governance Committee does not have a formal policy with regard to diversity, the Nominating and Corporate Governance Committee considers diversity in identifying director nominees, including personal characteristics such as race, gender, age and cultural background. The Nominating and Corporate Governance Committee assesses the effectiveness of its efforts at pursuing diversity through its periodic evaluation of the Board’s composition.

~~Director Independence~~

TABLE OF CONTENTS

Director Independence

The Board has determined, after considering all of the relevant facts and circumstances, that Messrs. Diaz, Douglas, Dunbar and Wyszomierski and ~~Ms.~~Mses. Drake, Isbell and ~~Ms. Drake~~Sansone are “independent” as defined under NYSE listing standards. This means that none of those independent directors and nominees has any direct or indirect material relationship with the Company and its management, either directly or as a partner, stockholder or officer of an organization that has a relationship with us.

~~Board Leadership Structure~~Board Leadership Structure

The Board is led by our ~~Chief Executive Officer~~Chairman and ~~Chairman,~~CEO, Mr. Black. As stated in our Corporate Governance Guidelines, the Board has the flexibility to decide when the positions of Chairman and CEO should be combined or separated and whether an executive or independent director should be Chairman. This approach is designed to allow the Board to choose the most appropriate leadership structure for the Company to serve the interests of the Company and our stockholders at the relevant time. At this point in time, the Board believes that the Company and its stockholders are best served by having Mr. Black serve as both Chairman and CEO. As the officer ultimately responsible for the day-to-day ~~operation~~operations of the Company and for execution of its strategy, the Board believes Mr. Black is the director best qualified to act as Chairman and to lead Board discussions regarding the performance of the Company. The structure also reinforces accountability for the Company’s performance at the highest levels.

Our Corporate Governance Guidelines also provide that, when the position of Chairman is not held by an independent director, a lead director (“Lead Director”) will be appointed by the ~~Board. In June 2017, the~~ independent members of the ~~Board appointed~~Board. William W. Douglas III ~~to serve~~serves as our Lead Director. As Lead Director, Mr. Douglas, among other things, serves as a liaison between independent directors and the Chairman, consults with the Chairman of the Board on, and approves, the schedules, agendas and information provided to the Board for each meeting and on other pertinent matters, has the ability to call meetings of ~~non-management and~~ independent directors, chairs executive sessions of ~~non-management and~~ independent directors, and consults with the CEO on matters relating to management effectiveness and Board performance. Mr. Douglas is available for consultation and direct communication with ~~major shareholders~~stockholders upon request. The independent members of the Board selected Mr. Douglas for this role because of, among other attributes, his extensive board room experience, leadership qualities and ability to facilitate meaningful discussion by encouraging participation, soliciting feedback, ensuring all viewpoints are heard and considered and building consensus among the group.

The Board believes that Mr. Black, as Chairman and CEO, together ~~our~~with an empowered and independent Lead Director, ~~and Mr. Black~~ provide the appropriate leadership and Board oversight of our Company and facilitate effective functioning of both the Board and the management team.

~~Meetings~~Meetings of the ~~Board~~ Board and ~~Attendance~~ Attendance at the ~~Annual Meeting~~ Annual Meeting

The Board held four meetings during the ~~2018~~2023 Fiscal ~~Year.~~Year, three of which were held in person. Each of our current directors attended ~~at least 75%~~all of the ~~total number of~~ meetings of the Board and any committees of which he or she was a member held during the ~~2018~~2023 Fiscal Year. Directors are ~~encouraged~~expected to attend our annual meetings, and all of our directors attended our ~~2018~~2023 Annual Meeting of Stockholders.

Executive Sessions

~~TABLE OF CONTENTS~~

~~Executive Sessions~~

Executive sessions, which are meetings of the ~~non-management~~independent members of the Board, are held at each of the Board’s quarterly meetings. In addition, at least once a year, the independent directors meet in a private session that excludes management and non-independent directors, and the ~~non-management~~independent directors meet with the ~~Chief Executive Officer~~CEO without the other executive officers being present, with the Lead Director presiding at such sessions. The committees of the Board, as described more fully below, also meet regularly in executive session.

~~Corporate Governance Guidelines~~Corporate Governance Guidelines

The Board has adopted Corporate Governance Guidelines to address significant corporate governance issues. A copy of these guidelines is available on our website at ~~http://~~investors.siteone.com/corporate-governance. These guidelines provide a framework for our corporate governance initiatives and cover topics including, but not limited to, director qualification and responsibilities, Board composition, conflicts of interest, director compensation and

management and succession planning. The Nominating and Corporate Governance Committee is responsible for overseeing and reviewing the guidelines and reporting and recommending to the Board any changes to the guidelines.

Corporate Responsibility and Stakeholder Impact

At SiteOne, we believe our operational initiatives drive value for all of our stakeholders and will continue to make us stronger and more resilient for many years to come. We continue to enhance our sustainability profile in response to conversations with our stakeholders — particularly feedback from our stockholders received as part of our annual stockholder outreach program. We believe it is important to provide our stockholders with important information about our sustainability-related governance performance. As part of this commitment to transparency, we published our annual IMPACT Report in October 2023, which details our programs and progress across a number of important corporate responsibility topics. Our IMPACT Report follows the recommendations of the SASB and TCFD frameworks and includes the disclosure of quantitative safety, human capital and sustainability metrics relevant to our business and industry. In addition, we have incorporated feedback from our stockholder outreach program to enhance our IMPACT Report disclosures. We will continue to dedicate resources to measuring, reporting on, and improving our sustainability efforts in the coming years. Our IMPACT Report, as well as several other corporate policies, including our Human Rights Policy, Supplier Code of Conduct and ~~Financial Code~~Environmental Policy are available on our website at www.siteone.com/impact.

In 2022, we formed our Stakeholder Impact Committee, which assists the Nominating and Corporate Governance Committee and our executive leadership team in (a) setting general strategy related to human capital management and sustainability, (b) developing, implementing, and monitoring initiatives and policies based on that strategy, (c) overseeing communications with SiteOne stakeholders, including associates, customers, suppliers, stockholders and the community with respect to human capital management and sustainability, and (d) monitoring and assessing developments related to, and improving SiteOne’s understanding of ~~Ethics~~sustainability. The Stakeholder Impact Committee held four meetings during the 2023 Fiscal Year.

Our Board, specifically the Nominating and Corporate Governance Committee, oversees our environmental stewardship and corporate responsibility initiatives, including policies and operational controls of environmental, health and safety, social risks, and climate-related risks and opportunities, and is committed to supporting our efforts to operate as a good neighbor in our communities. In May 2021, the Board adopted revisions to the Nominating and Corporate Governance Committee’s charter to memorialize the committee’s responsibility for oversight of the Company’s environmental stewardship and corporate responsibility matters, including climate-related risks and opportunities. Additionally, the Audit Committee of the Board oversees the annual enterprise risk management (“ERM”) process which includes the oversight of risk mitigation controls and procedures for the material risks identified by the Company. In 2023, the Audit Committee’s ERM process included the assessment of potential climate-related risks, key mitigation efforts and the Company’s current level of risk.

Financial Code of Ethics and Business Code of Conduct

We have a Financial Code of Ethics that applies to the ~~Chief Executive Officer,~~CEO, Chief Financial Officer and Controller, or persons performing similar functions, and other designated officers and associates, including the primary financial officer of each of our business units and the Treasurer. We also have a Business Code of Conduct and Ethics ~~(“BCCE”)~~ that applies to all of our directors, officers and associates. The Financial Code of Ethics and the ~~BCCE~~Business Code of Conduct and Ethics each address matters such as conflicts of interest, confidentiality, fair dealing and compliance with laws and regulations. The Business Code of Conduct and Ethics contains a 24-hour Compliance and Ethics Hotline to anonymously report compliance or ethics concerns. These submissions, if any, are reviewed at least quarterly by the Audit Committee. Copies of the Financial Code of Ethics and the ~~BCCE~~Business Code of Conduct and Ethics are available ~~without charge on the investor relations portion of~~at our website at ~~http://~~investors.siteone.com/corporate-governance. We also disclose certain internal review procedures and metrics related to complaints received via the Hotline in our IMPACT Report, available at our website at www.siteone.com/impact.

~~Board Committees~~Board Committees

The Board maintains an Audit Committee, a Human Resources and Compensation Committee and a Nominating and Corporate Governance Committee. All members of the Audit Committee, Human Resources and Compensation Committee and Nominating and Corporate Governance Committee are independent.

TABLE OF CONTENTS

The following table shows the current members of each committee, as well as the number of meetings held during the ~~2018~~2023 Fiscal Year. At this time, the Board does not expect any changes to the composition of the committees ~~for the 2019 Fiscal Year.~~in 2024.

Audit Committee

Our Audit Committee is responsible, among its other duties and responsibilities, for assisting the Board in overseeing the quality and integrity of our financial statements, our accounting and financial reporting processes, the audits of our financial statements, the qualifications and independence of our independent registered public accounting firm, the effectiveness of our internal control over financial reporting and the performance of our internal audit function and independent registered public accounting firm. Our ~~audit committee~~Audit Committee also reviews and assesses the qualitative aspects of our financial reporting, our processes to manage business and financial risks, and our compliance with significant applicable legal, ethical and regulatory requirements. Our ~~audit committee~~Audit Committee is directly responsible for the appointment, compensation, retention and oversight of our independent registered public accounting firm. The charter of our Audit Committee is available ~~without charge~~ on our website at ~~http://~~investors.siteone.com/~~corporate-governance~~corporate-governance/governance-documents.

The members of our Audit Committee are Messrs. Douglas (Chair), Diaz and Wyszomierski.

The Board has determined that Messrs. Douglas, Diaz and Wyszomierski are “independent” as defined under NYSE and Securities Exchange Act of 1934, as amended (“Exchange Act”), rules and regulations. The Board has designated each member of the Audit Committee as an “audit committee financial expert,” and each of them has been determined to be “financially literate” under the NYSE rules.

The charter of our Audit Committee states that no director may serve on the Audit Committee if such director simultaneously serves on the audit committee of more than two other public companies, unless the Board determines that such simultaneous service would not impair the ability of such director to effectively serve on the Audit Committee. At present, Messrs. Douglas and Diaz do not sit on more than two other audit committees of public companies. Mr. Wyszomierski currently serves on three other audit committees of public companies. However, both the Board and the Nominating and Corporate Governance Committee reviewed Mr. Wyszomierski’s service on other boards and determined that such simultaneous service will not impair his ability to serve on the Company’s Audit Committee and that the Audit Committee ~~will benefit~~benefits from Mr. ~~Wyzomierski’s~~Wyszomierski’s service on other audit committees and experience as a chief financial officer.

The Secretary may communicate with the sender for any clarification. In addition, the Secretary will promptly forward to the chair of the Audit Committee any communication alleging legal, ethical or compliance issues by management or any other matter deemed by the Secretary to be potentially material to the Company. As an initial matter, the Secretary will determine whether the communication is a proper communication for the Board. The Secretary will not forward to the Board, any committee or any director communications of a personal nature or not related to the duties and responsibilities of the Board, including, without limitation, junk mail and mass mailings, business solicitations, routine customer service complaints, new product or service suggestions, opinion survey polls or any other communications deemed by the Secretary to be immaterial to the Company.

auditing matters and the confidential, anonymous submission by associates of the Company of concerns regarding questionable accounting or auditing matters. These submissions, if any, are reviewed at least quarterly by the Audit Committee.

~~Risk Oversight~~

TABLE OF CONTENTS

Risk Oversight

The Board as a whole has responsibility for overseeing our risk management. The Board exercises this oversight responsibility directly and through its committees. The oversight responsibility of the Board and its committees is informed by reports from our management team and from our internal audit department that are designed to provide visibility to the Board about the identification and assessment of key risks and our risk mitigation strategies. The full Board has primary responsibility for evaluating strategic and operational risk management, and succession planning. Our Audit Committee has the responsibility for overseeing our major financial and accounting risk exposures and the steps our management has taken to monitor and control these exposures, ~~including policies and procedures for assessing and managing risk, as well as~~ oversight of ~~compliance related to~~ legal and regulatory ~~exposure~~compliance and ~~cybersecurity.~~oversight of our information security program, including monitoring and controlling material cybersecurity risks. The Audit Committee meets regularly with our General Counsel. The Human Resources and Compensation Committee evaluates risks arising from our human capital management and compensation policies and practices, as more fully described below. The Audit Committee and the Human Resources and Compensation Committee provide reports to the full Board regarding these and other matters.

~~Compensation Risk Assessment~~Compensation Risk Assessment

In March ~~2019,~~2024, the Human Resources and Compensation Committee assessed our compensation policies and practices to evaluate whether they create risks that are reasonably likely to have a material adverse effect on the Company. Based on its assessment, the Human Resources and Compensation Committee concluded that the Company’s compensation policies and practices do not create incentives to take risks that are reasonably likely to have a material adverse effect on the Company. We believe we have allocated our compensation among base salary, short-term incentives and long-term equity in such a way as to not encourage excessive risk taking. Additionally, the incentive compensation program uses multiple performance metrics tied to growth, profitability, asset efficiency and strategic priorities, as well as absolute stock price appreciation, to encourage a balanced focus. Finally, meaningful risk mitigators are in place, including stock ownership guidelines and retention ratio, clawback provisions (including the ability to recoup compensation for fraud, misconduct, or illegal activity), anti-hedging and pledging policies and independent Human Resources and Compensation Committee oversight.

~~Stock Ownership~~Stock Ownership and ~~Retention Guidelines~~ Retention Guidelines

~~The~~

In order to further align the long-term interests of Company leaders with the interests of our stockholders, the Company has established stock ownership and retention guidelines for our CEO and other executive officers ~~in order~~and has adopted a Non-Employee Director Equity Ownership Policy for non-employee directors. These policies limit our CEO, each member of the senior leadership team who reports directly to ~~further align~~ the ~~long-term interests of our executive officers with those of our stockholders. Also, the deferred stock units granted to our~~CEO (each a “Covered Executive”) and non-employee directors ~~under the Omnibus Incentive Plan pursuant to our non-employee director compensation policy are granted on a fully vested basis but will not settle into the Company’s~~from selling shares of common stock ~~until after~~unless they own shares equal to at least 6x and 2x of annual base salaries for our CEO and Covered Executives, respectively, and 5x the ~~director receiving the grant has ceased to serve as a~~annual cash retainer for non-employee ~~director on the Board or a change in control.~~directors. Further, unexercised stock options, unvested RSUs and unsettled PSUs do not count towards meeting these guidelines. For more information about our stock ownership and retention guidelines, see the discussion in the Compensation Discussion and Analysis under the heading ~~“Stock~~“Executive Officer Stock Ownership and Retention Guidelines” on page ~~36.~~45 and under “Director Compensation — Non-Employee Director Stock Ownership and Retention Guidelines” on page 56. Currently, each non-employee director complies with the Non-Employee Director Stock Ownership and Retention Guidelines, and our CEO and each Covered Executive complies with the Executive Officer Stock Ownership and Retention Guidelines.

~~Anti-Hedging Policy~~Anti-Hedging and Anti-Pledging Policy

Our directors, executive officers and all other associates are prohibited from entering into hedging or monetization transactions designed to limit the financial risk of ownership of the Company’s securities. These include prepaid variable forward contracts, equity swaps, collars, exchange funds and other similar transactions, as well as speculative transactions in derivatives of the Company’s securities, such as puts, calls, options (other than those granted under our compensation plans) or other derivatives. Our directors and executive officers are also prohibited from holding the Company’s securities in a margin account or otherwise pledging such securities as collateral for a loan.

TABLE OF CONTENTS

Board and ~~Committee Evaluations~~ Committee Evaluations

The Board conducts a ~~detailed~~thorough annual self-evaluation process. The charters of each of the Audit Committee, Human Resources and Compensation Committee and Nominating and Corporate Governance Committee require an annual performance evaluation. Each committee compares its performance with the requirements of its

~~TABLE OF CONTENTS~~

charter and sets forth the goals and objectives of the committee for the upcoming year. As a result of these evaluations, we also update and revise our processes and practices, providing feedback to the Board’s committees and members as needed to ensure the Board ~~and each committee operate~~operates in the most efficient and effective manner possible.

~~Conflicts~~Conflicts of ~~Interest~~ Interest

~~Our BCCE~~

The Business Code of Conduct and Ethics and our Corporate Governance Guidelines govern our conflicts of interest policy. The ~~BCCE~~Business Code of Conduct and Ethics requires ~~employees~~associates to avoid conflicts of interest, defined as situations where the person’s private interests or professional interests interfere in any way — or even appear to interfere — with the interests of the Company. The ~~BCCE~~Business Code of Conduct and Ethics requires all conflicts of interest between the Company and its ~~employees~~associates to be disclosed to an immediate supervisor or the General Counsel. The Corporate Governance Guidelines require directors to promptly inform the Chairman of the Board or the Chair of the Audit Committee if an actual or potential conflict of interest arises. Directors shall recuse themselves from any discussion or decision involving another firm or company with which the director is affiliated or other matters with respect to which the director has a personal conflict.

~~Related Person Transactions~~Related Party Transactions

See “General Information — Certain Relationships and Related Party Transactions” on page 5661 for a discussion of our policies and procedures for related person transactions.

~~Director Change~~Director Change in ~~Circumstances~~ Circumstances

In the event of a significant change in circumstances involving a director’s employment status, professional position or substantial commitments to a business or governmental organization, the director must offer to tender his or her resignation from the Board for consideration by the Nominating and Corporate Governance Committee and the Board. The Nominating and Corporate Governance Committee will evaluate the change in circumstances and will recommend to the Board whether the director should continue to serve as a member of the Board or whether the Board should accept the resignation.

~~Succession Planning~~Succession Planning and ~~Management Development~~ Management Development

Succession planning and talent development are important at all levels within our organization, and accordingly, succession planning and management development are discussed ~~at least annually~~regularly by the Board and the ~~Chief Executive Officer.~~CEO. The Board oversees management’s succession plan for key positions at the senior officer level. Our Corporate Governance Guidelines require that each year the ~~Chief Executive Officer~~CEO reports to the Board on succession planning, including the principles and process for chief executive officer selection and performance review, as well as plans regarding succession in the case of an emergency or the retirement of the ~~Chief Executive Officer.~~CEO. The Human Resources and Compensation Committee, with the full Board in attendance, also reviews succession planning and talent development of our leadership team at each of its meetings. The Nominating and Corporate Governance Committee has adopted a written CEO succession plan that includes actions to be taken in the event of a planned or unexpected absence (both short-term and longer-term) of the CEO. We believe continuity of leadership is critical to our ongoing success and that our process is effective in preparing us for sustained, long-term effective leadership.

~~Overboarding~~Overboarding

Our Corporate Governance Guidelines state that no director may serve on more than four other public company boards. No director may serve as a member of the Audit Committee if such director serves on more than two other public company audit committees, unless the Board determines that such simultaneous service would not impair the director’s ability to serve effectively on the Company’s Audit Committee.

~~Mandatory Retirement Age~~

TABLE OF CONTENTS

Mandatory Retirement Age

Our Corporate Governance Guidelines also require directors to retire from the Board when they reach the age of 72, although a director elected to the Board prior to his or her 72nd birthday may continue to serve until the next annual meeting. While directors generally will not be nominated for election or ~~reelection~~re-election to the Board after their 72nd birthday, the full Board may nominate candidates over 72 for election or ~~reelection~~re-election in special circumstances.

Compensation Clawback

Our Corporate Governance Guidelines provide that, in the event the Company is required to issue a restatement of its financial statements due to material noncompliance with applicable financial reporting requirements, the Board may, among other things, clawback an executive’s incentive compensation for the three-year period preceding the date of the financial restatement which is in excess to what would have been paid if the financial information had been correctly reported as set forth in such restatement. The Corporate Governance Guidelines further provide that, if an individual’s misconduct was a contributing factor to the Company having to restate any of its financial statements or constituted fraud, bribery or other illegal act which adversely affected the Company’s financial position or reputation, then the Board may, in its discretion, clawback all or a portion of an executive’s incentive compensation to the extent such incentive compensation was granted on or after the effective date of February 5, 2020.

In addition, the Board has adopted a clawback policy (the “Clawback Policy”) in order to comply with applicable laws and NYSE listing standards that requires the Company to clawback incentive-based compensation in the event the Company issues a restatement of its financial statements, to the extent such incentive-based compensation received by the individual exceeds the amount the individual would have received based on the restated financial statements. The Clawback Policy does not supersede the Board’s ability to clawback incentive compensation under our Corporate Governance Guidelines but, instead, supplements that ability.

PROPOSAL 2: APPROVAL OF AMENDMENT TO THE COMPANY’S CHARTER
TO LIMIT THE LIABILITY OF CERTAIN OFFICERS

Background of Proposal ~~3: Advisory Vote~~

The Board has unanimously adopted a resolution to ~~Approve Executive Compensation~~amend and restate our Third Amended and Restated Certificate of Incorporation (the “Charter”), subject to stockholder approval, to provide for the elimination or limitation of monetary liability of specified executive officers of the Company for breach of the duty of care. Our Charter currently provides for the Company to limit the monetary liability of directors in certain circumstances pursuant to and consistent with Section 102(b)(7) of the General Corporation Laws of Delaware (“DCGL”). Effective August 1, 2022, Section 102(b)(7) of the DCGL was amended to permit a corporation’s certificate of incorporation to include a provision eliminating or limiting monetary liability for certain senior corporate officers for breach of their duty of care in certain limited circumstances (the “Section 102(b)(7) Amendment”).

~~We provide our~~If stockholders approve this proposal at the Annual Meeting, the Company will file a Fourth Amended and Restated Certificate of Incorporation (the “Amended Charter”) in the form attached hereto as Appendix B (marked to show the proposed modifications). In accordance with the DGCL, however, our Board may elect to abandon the Amended Charter without further action by the stockholders at any time prior to the effectiveness of the filing of the Amended Charter with the Secretary of State of the State of Delaware, notwithstanding stockholder approval of the Amendment.

Rationale for the Proposed Amended Charter

As part of its annual ~~opportunity to cast an advisory vote to approve the compensation~~review of our ~~NEOs. This non-binding advisory vote, commonly known~~corporate governance standards and practices, the Board considered the benefits and challenges of eliminating our officers’ personal liability under certain specified circumstances as permitted by the Section 102(b)(7) Amendment. Delaware law has long permitted Delaware corporations to protect directors from personal liability for monetary damages associated with breaches of the duty of care, but that protection did not extend to a ~~“say~~Delaware corporation’s officers. However, the nature and role of corporate officers often requires them to make crucial decisions in response to time-sensitive matters, which can create significant risk of investigations, claims or actions seeking to impose liability on ~~pay” vote, gives our stockholders the opportunity to express their views on our NEOs’ compensation on an annual basis. This vote is not intended~~them in hindsight, regardless of merit. Consequently, stockholder plaintiffs routinely bring claims against officers that would otherwise be dismissed if brought against directors. The Section 102(b)(7) Amendment was adopted to address ~~any specific item of compensation but rather~~ the ~~overall compensation of~~inconsistent treatment between officers and directors and curtails rising litigation and insurance costs for stockholders.

As is currently the case with directors under our ~~NEOs and~~Charter, the ~~philosophy, policies and practices described in this Proxy Statement. At last year’s annual meeting of stockholders, approximately 98%~~Amended Charter would not protect officers from personal liability for monetary damages for breach of the ~~votes cast were~~duty of loyalty, acts or omissions not in ~~support~~good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit. Nor would the Amended Charter protect such officers from liability for claims brought by or in the right of the ~~compensation of our NEOs.~~

corporation, such as derivative claims. The Board ~~and Compensation Committee are dedicated~~believes it is appropriate to ~~ensuring that our executive~~provide this protection to officers be compensated competitively with the market and consistently with our business strategy, sound corporate governance principles, and stockholder interests and concerns. To do so, the Compensation Committee uses a combination of short- and long-term incentive compensation to motivate and reward executives who have the ability to significantly influence our long-term financial success and who are responsible for effectively managing our operations in a way that maximizes stockholder value.

~~We believe that our compensation program is effective in achieving our goals, has contributed~~ to the ~~Company’s success~~fullest extent permitted by law in order to continue to attract and retain top talent. This protection has long been afforded to directors, and accordingly, the Board believes that this proposal provides consistency and is ~~strongly aligned with~~in the ~~long-term~~best interests of ~~our stockholders~~the Company and ~~that the total compensation packages provided to our NEOs are reasonable. For these reasons, the Board is asking stockholders to vote “FOR” the following resolution:~~

“RESOLVED, that the stockholders approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed in the Compensation Discussion and Analysis, the accompanying compensation tables and the related narrative disclosure in the Company’s Proxy Statement for the 2019 Annual Meeting of Stockholders.”

As you consider this Proposal 3, we urge you to read the “Compensation Discussion and Analysis” section of this Proxy Statement beginning on page 29 for additional details on our executive compensation, including the more detailed information regarding our compensation philosophy and objectives.

As an advisory vote, Proposal 3 is not binding on the Board or the Compensation Committee, will not overrule any decisions made by the Board or the Compensation Committee, or require the Board or the Compensation Committee to take any specific action. Although the vote is non-binding, the Board and the Compensation Committee value the opinions of our stockholders and will carefully consider the outcome of the vote when making future compensation decisions for our NEOs.its stockholders.

Required Vote

~~Approval~~The affirmative vote of the ~~compensation of our NEOs as presented in this Proxy Statement requires the affirmative vote~~holders of a majority of the voting power of all of the outstanding shares ~~present, either in person or by proxy,~~of common stock then entitled to vote at the Annual ~~Meeting.~~Meeting is required to adopt this proposal pursuant to our Charter. Broker non-votes and shares that are voted “abstain” are treated as the same as voting “against” this proposal.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE ~~BOARD~~

~~The Board unanimously recommends that you vote “FOR” the approval of the compensation of our named executive officers as presented in this Proxy Statement.~~

~~Executive Compensation~~

~~Compensation Discussion and Analysis~~

In this section we provide information regarding our philosophies, plans and practices with respect to executive compensation. This section also provides information regarding the material elements of compensation that were paid to or earned by our NEOs for the 2018 Fiscal Year. Our NEOs for the 2018 Fiscal Year were:

•

~~Doug Black, Chief Executive Officer~~

•

~~John Guthrie, Executive Vice President, Chief Financial Officer and Assistant Secretary~~

•

~~Pascal Convers, Executive Vice President, Strategy, Development and Investor Relations~~

•

~~Briley Brisendine, Executive Vice President, General Counsel and Secretary~~

•

~~Ross Anker, Executive Vice President, Category Management, Marketing and IT~~

~~Compensation Philosophy and Objectives~~

Our executive compensation program is designed to encourage high performance and results that will create value for us and our stockholders while avoiding unnecessary risks. In particular, our executive compensation program has the following key objectives:

•

~~To pay for performance.~~

•

~~To reward our executives with equity in the Company in order to align their interests with the interests of our stockholders and allow our executives to share in our stockholders’ success.~~

•

~~To create a performance culture and maintain morale, which we believe drives exceptional customer service and safety performance.~~

•

~~To enable us to attract, motivate and retain top executive talent.~~

At last year’s annual meeting of stockholders our executive compensation program received strong stockholder support, with approximately 98% of votes cast in favor of the compensation of our NEOs. We value the opinions of our stockholders, and the Compensation Committee takes seriously the feedback it receives. Accordingly, the Compensation Committee will continue to consider the outcome of our say-on-pay votes and our stockholders’ views when making future compensation decisions.

~~Determination of Executive Compensation~~

~~Compensation Committee~~

The Compensation Committee is responsible for reviewing and approving the compensation and benefits of our executives (including our NEOs), directors and certain consultants, approving equity incentive compensation and other incentive arrangements, and approving employment and related agreements. In performing these duties, the Compensation Committee is supported by its independent consultant and certain members of executive management, as described below.

~~Independent Consultant~~

For the 2018 Fiscal Year, the Compensation Committee engaged Pearl Meyer as an independent consultant, and FW Cook as an independent consultant. Pearl Meyer reports to and is directed by the Compensation Committee, and provides no other services to the Company. The Compensation Committee considered the independence of Pearl Meyer in light of applicable SEC rules and NYSE listing standards and concluded that Pearl Meyer was appropriately independent and free from potential conflicts of interest. FW Cook reports to and is directed by the Compensation Committee, and provides no other services to the Company. The Compensation Committee considered the independence of FW Cook in light of applicable SEC rules and NYSE listing standards and concluded that FW Cook was appropriately independent and free from potential conflicts of interest.

To assist in evaluating our compensation program, in November 2017, the Compensation Committee worked with Pearl Meyer to establish the industry peer group listed below, which consists of companies of

~~TABLE OF CONTENTS~~

similar size and complexity, as well as companies with whom we compete for executive talent. In reviewing the appropriateness of our peer group, Pearl Meyer considered, among other factors, total market capitalization and revenue within the wholesale distribution market. At the time of Pearl Meyer’s analysis, our market capitalization approximated the peer group median and our revenues approximated the peer group 25th percentile. Pearl Meyer then conducted a competitive market assessment of the base salary, target total cash compensation (base salary plus target short-term incentive opportunity), and target total direct compensation (base salary plus target short-term incentive opportunity plus target long-term incentive opportunity) for certain senior leadership positions, including each of our NEOs, compared to similarly-situated executives at the peer group companies. Our executive compensation program aims to provide for total compensation for our executives at approximately the 50th ~~percentile of our peer group.~~

~~Industry Peer Group~~

	~~Watsco Inc.~~			~~GMS Inc.~~
	~~Beacon Roofing Supply, Inc.~~			~~Central Garden & Pet Company~~
	~~BMC Stock Holdings, Inc.~~			~~TopBuild Corp.~~
	~~MSC Industrial Direct Co., Inc.~~			~~Summit Materials, Inc.~~
	~~The Scotts Miracle-Gro Company~~			~~Advanced Drainage Systems, Inc.~~
	~~Pool Corporation~~			~~DXP Enterprises, Inc.~~
	~~Applied Industrial Technologies, Inc.~~			~~Installed Building Products, Inc.~~

~~Executive Management~~

Certain members of executive management are involved in the executive compensation determination process. For example, our Senior Vice President, Human Resources provides requested information and perspectives on the compensation program, and our General Counsel provides legal and regulatory advice and perspectives. In addition, our Chief Executive Officer makes specific recommendations for compensation levels and program designs for executives (other than himself) and our Chief Financial Officer may provide input on financial goals. Our Chief Executive Officer, Senior Vice President, Human Resources, and General Counsel generally attend Compensation Committee meetings, but are excused when their compensation is being discussed.

~~Elements of Our Executive Compensation Program~~

To create a “pay for performance” environment, compensation is weighted toward at-risk compensation, consisting of salary, short-term annual cash incentive compensation, long-term equity incentive compensation and certain other benefits. Our relatively low base salaries, which are, in the aggregate, between the 25th ~~and 50~~th percentile of our peer group, tie a large portion of our NEOs’ total compensation to Company performance and long-term stock growth. In addition, our short-term cash incentive program approximates the median of our peer group, includes aggressive Adjusted EBITDA and Company Net Promoter Score (“NPS”) targets and challenging Company safety and individual performance goals. In addition, the Adjusted EBITDA, Company NPS and Company safety and individual performance components of our annual incentive awards are capped at 250%, 150% and 150% of “target”, respectively. Our long-term equity inventive program provides for extended vesting schedules and prohibits repricing of underwater options, and for the 2019 Fiscal Year, includes PSUs with three-year relative and absolute performance criteria and capped payouts at 200% of “target.” And finally, while we provide customary benefits as discussed below, we provide virtually no perquisites to our executives.

Set forth below is a chart outlining each element of our compensation program for our executive officers and the objectives of each component, and the key measures used in determining each component. For 2018, our NEOs’ target total direct compensation, which includes base salary, target short-term cash incentive and long-term equity awards, approximated the median of peer group practice.

~~TABLE OF CONTENTS~~

~~Pay Component~~			~~Objective of Pay Component~~
~~Base Salary~~			• ~~To attract and retain a high-performing leadership team~~
~~Short-Term Annual Cash Incentives~~			• ~~To reward achievement of short-term business objectives and results, such as Adjusted EBITDA, Company NPS, Company safety and individual performance goals~~
~~Long-Term Equity Awards~~			• ~~To align executive and stockholder interests, create “ownership culture” and provide retention incentives~~
~~Other Benefits~~			• ~~To provide a safety net of protection in the case of illness, disability, death or retirement, through health, disability and life insurance, 401(k) retirement plan and other employee benefits~~

~~Base Salary~~

Base salaries are set to attract and retain high-performing executive talent. The determination of any particular executive’s base salary is based on personal performance, experience in the role, competitive rates of pay for comparable roles, significance of the role to the Company, the availability of potential replacement executives and anticipated economic conditions. Each year, the Compensation Committee considers merit and market-based salary increases, using data from our peer group, for our executives generally, including our NEOs. Based on these factors, in February 2018, the Compensation Committee approved salary increases for each of our NEOs in the range of 2.7% to 6.3%. Mr. Black, however, declined a base salary increase for the 2018 Fiscal Year. The base salaries paid to each of our NEOs in our 2018 Fiscal Year are shown in the “Summary Compensation Table” on page 38.

~~Short-Term Annual Cash Incentives~~

Our annual cash incentives are designed to focus our NEOs on achieving superior performance against business objectives and results for the Company as a whole and, in addition, reward them for the achievement of specific individual performance and/or other goals which the Compensation Committee and Chief Executive Officer (in the case of NEOs other than himself) subjectively determine based on its assessment of the executive’s performance during the year. By conditioning a significant portion of our NEOs’ potential total cash compensation on the Company’s achievement of clearly defined metrics, we reinforce our focus on creating a strong pay-for-performance culture.

All of our NEOs were eligible in the 2018 Fiscal Year to receive cash incentive bonuses based on the achievement of a pre-established annual financial performance metric approved by the Compensation Committee. For the 2018 Fiscal Year, each NEO had a target incentive opportunity expressed as a percentage of his salary for the year. The threshold, target, stretch and actual percentages of target for our NEOs for the 2018 Fiscal Year were as follows:

Threshold(1)

Target(1)

~~Expressed as a percentage of the target bonus opportunity.~~

~~TABLE OF CONTENTS~~

The Compensation Committee selected Adjusted EBITDA as the financial performance metric for our NEOs’ annual incentive opportunity, measured against the Adjusted EBITDA goals established by the Compensation Committee in the beginning of the year. In order to ensure our team continues to deliver outstanding customer service, the Compensation Committee also utilized Company-wide NPS as a component of each NEO’s annual incentive award, with a target score set at 65 and a maximum payout (150% of target) for a score of 80 or higher. This NPS target score represents a meaningful increase of 7.3% over our 2017 company-wide NPS score. The Compensation Committee also evaluated each NEO’s achievement of individual performance goals. The Compensation Committee subjectively assessed Mr. Black’s achievement with respect to the Company safety performance measure and Mr. Black’s individual performance measures and, with respect to the other NEOs, Mr. Black evaluated the performance of each NEO based on his individual performance measures and made a recommendation to the Compensation Committee. The Company safety objective is achieved through reduced incident rates, improvement in safety of operating company vehicles and facilities and improved safety behaviors of company associates. The following table shows the weighting of the 2018 Fiscal Year performance metrics for each NEO, expressed as a percentage of his 2018 Fiscal Year total bonus opportunity.

Adjusted EBITDA was calculated using EBITDA for the Company for the fiscal year, as further adjusted for items such as stock-based compensation expense, (gain) loss on sale of assets, financing fees, acquisitions and other adjustments. See Appendix A to this Proxy Statement for a reconciliation of Adjusted EBITDA to Net income (loss), the corresponding GAAP financial measure.

~~(2)~~

In order to mitigate the impact of acquisitions not reflected in the levels of achievement for the Adjusted EBITDA performance metric originally approved by the Compensation Committee in February 2018, in August 2018, the Compensation Committee increased the threshold, target and stretch goals by $7.0 million, $7.0 million and $8.0 million, respectively, to take into account anticipated Adjusted EBITDA contributions from acquisitions completed during the first half of the 2018 Fiscal Year. Acquisitions completed during the second half of the 2018 Fiscal Year were excluded from the calculation of Adjusted EBITDA for purposes of determining annual bonuses.

The Adjusted EBITDA weighted performance multiplier is determined by linear interpolation of the percentage achievement between the threshold, target and stretch levels and for achievement beyond stretch level.

Company NPS is based on responses from a customer survey regarding customer experience. Respondents to the survey are categorized as detractors (0 – 6 score for likelihood to recommend), passives (7 – 8), and promoters (9 – 10). Company NPS is then calculated by subtracting the percentage of detractors from the percentage of promoters.

To determine the level of achievement of the NEOs’ individual performance criteria, the Compensation Committee subjectively assessed Mr. Black’s achievement with respect to the Company safety and his individual performance measures. For Fiscal Year 2018, Mr. Black declined the portion of his annual incentive award related to Company safety, which comprised 10% of his total award opportunity. With respect to the other NEOs, Mr. Black evaluated the performance of each NEO based on their individual performance measures and made a recommendation to the Compensation Committee. These individual criteria were related to specific individual categories of performance measures, as described below.

			~~Company Safety and Individual Performance Categories~~
~~Mr. Black~~			• ~~Company safety improvement; improvements in Company diversity and inclusion; execution of Company foundation-building initiatives~~
~~Mr. Guthrie~~			• ~~Finance team development and strategic planning; field reporting; financial reporting and Sarbanes-Oxley compliance~~
~~Mr. Convers~~			• ~~Acquisition growth, integration and performance; investor relations leadership~~
~~Mr. Brisendine~~			• ~~Corporate governance oversight and execution; risk management enhancements; field operations support; customer service initiative progress~~
~~Mr. Anker~~			• ~~Gross margin growth; IT team development and strategic planning; execution of marketing strategies~~

Achievement of the Adjusted EBITDA, Company NPS and the individual performance measures, taken together, resulted in bonus payments for the 2018 Fiscal Year of $554,696 to Mr. Black, $135,700 to Mr. Guthrie, $163,686 to Mr. Convers, $179,479 to Mr. Brisendine and $139,760 to Mr. Anker. The 2018 annual bonus plan award paid to each of our NEOs is shown in the “Summary Compensation Table” on page 38 ~~under the “Non-Equity Incentive Plan Compensation” column.~~

~~Long-Term Equity Incentives~~

In connection with our initial public offering in 2016, we adopted the SiteOne Landscape Supply, Inc. 2016 Omnibus Equity Incentive Plan (the “Omnibus Incentive Plan”), which serves as the primary vehicle for providing equity incentives to our associates and directors. In 2017, the Compensation Committee began making annual equity grants to our executives as part of our compensation program. In addition, the

~~TABLE OF CONTENTS~~

Compensation Committee may, from time to time, provide an equity award to one or more of our NEOs to retain and reward key talent or to reflect increased responsibilities. The Compensation Committee may also review and approve equity awards for promotions. For more information regarding the equity awards granted to our NEOs under the Omnibus Incentive Plan during the 2018 Fiscal Year, see the “Grants of Plan-Based Awards for 2018 Fiscal Year” table on page 39 ~~and the discussion under “Options and RSUs Granted During 2017, 2018 and 2019 under the Omnibus Incentive Plan” on page~~ 40 ~~below.~~

Prior to our initial public offering and the adoption of the Omnibus Incentive Plan, our NEOs participated in the Amended and Restated SiteOne Landscape Supply, Inc. Stock Incentive Plan (f/k/a CD&R Landscapes Parent, Inc. Stock Incentive Plan) (the “Stock Incentive Plan”). Each of our NEOs received options under the Stock Incentive Plan in connection with the commencement of their employment. For more information regarding these options, see the “Outstanding Equity Awards at 2018 Fiscal Year End” table on page 42 ~~and the discussion under “Options Granted During 2015 under the Stock Incentive Plan” on page~~ 40 ~~below.~~

~~Employment Arrangements and Severance Agreements~~

Under certain circumstances, we recognize that special arrangements with respect to an executive’s employment may be necessary or desirable. In connection with their commencement of employment, we entered into an employment agreement with Mr. Black setting forth the terms of his employment as our CEO and letter agreements with the other NEOs setting forth the terms of their employment with the Company. The agreements for each NEO provide for employment on an “at will” basis. Mr. Black’s employment agreement includes severance benefits, salary, bonus, benefits and the specific terms described below under “— Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — Material Terms of Employment Arrangements” on page 39 ~~and under “Potential Payments Upon Termination or Change in Control” on page~~ 42. The letter agreements with the other NEOs include salary, bonus, benefits and the specific terms described below under “— Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — Material Terms of Employment Arrangements” on page 39. In addition, we have entered into severance agreements with Messrs. Guthrie, Convers, Brisendine and Anker, which set forth certain severance benefits to be received by the executive upon a qualifying termination of employment. The severance arrangements with our NEOs operate with a “double trigger” in the event of a change of control, meaning severance payments do not occur unless the executive’s employment is involuntarily terminated (other than for cause or with good reason) within 12 months following a change-in-control. For a further discussion of these benefits, see below under “Potential Payments Upon Termination or Change in Control — Separation Benefits Agreements with Messrs. Guthrie, Convers, Brisendine and Anker” on page 43.

~~Other Benefits~~

The benefits provided to our NEOs are generally the same as those provided to our other salaried associates and include, but are not limited to, medical, dental, health, life, accident, hospitalization and disability insurance, and a tax-qualified 401(k) plan. Several of our NEOs and their spouses attend an annual customer event. In prior years, we have also covered certain of Mr. Convers’ commuting, lodging and other travel expenses.

~~Tax and Accounting Considerations~~

While the accounting and tax treatment of compensation generally has not been a consideration in determining the amounts of compensation for our executive officers, the Compensation Committee and management have taken into account the accounting and tax impact, including Section 162(m) (“Section 162(m)”) of the Internal Revenue Code, of various program designs to balance the potential cost to us with the value to the executive. Section 162(m), as most recently amended in December 2017 in connection with tax reform legislation, limits the deductibility of compensation paid to “covered employees” in excess of $1,000,000 in any taxable year. While the Compensation Committee may consider the impacts of Section 162(m) when determining executive compensation, it may authorize compensation payments that do not comply with the exemptions in Section 162(m) when it believes that such payments are appropriate to attract and retain executive talent.

~~TABLE OF CONTENTS~~

The expenses associated with executive compensation issued to our executive officers and other key associates are reflected in our financial statements. We account for stock-based programs in accordance with the requirements of ASC 718, Compensation-Stock Compensation, which requires companies to recognize in the income statement the grant date value of equity-based compensation issued to associates over the vesting period of such awards.

~~Stock Ownership and Retention Guidelines~~

The Company has established stock ownership and retention guidelines in order to further align the long-term interests of our executive officers with those of our stockholders. Our stock ownership guidelines require our CEO and each executive officer who reports directly to the CEO (each, a “Covered Executive”) to own shares of the Company’s common stock having an aggregate value equal to a multiple of annual base salary, as follows:

~~Position~~			~~Multiple~~
~~Chief Executive Officer~~			~~5x Annual Base Salary~~
~~Covered Executives~~			~~2x Annual Base Salary~~

~~Shares that count for purposes of ownership under the share ownership guidelines include (i) shares held directly by the individual and (ii) shares underlying in-the-money vested stock options.~~

Generally, the CEO and each Covered Executive will have five years from the date he or she becomes subject to these guidelines to achieve compliance. The CEO and each Covered Executive are required to hold 100% of shares acquired as a result of settlement of compensatory awards (net of any shares withheld for taxes) until ownership guidelines have been met. Also, the deferred stock units granted to our non-employee directors under the Omnibus Incentive Plan pursuant to our non-employee director compensation policy are granted on a fully vested basis but will not settle into the Company’s common stock until after the director receiving the grant has ceased to serve as a non-employee director on the Board or a change in control.

~~TABLE OF CONTENTS~~

~~Compensation Committee Report~~

This report shall not be deemed to be incorporated by reference by any general statement incorporating by reference this Annual Report into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, and shall not otherwise be deemed filed under such acts.

~~Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table~~

~~Material Terms of Employment Arrangements~~

On April 21, 2014, the Company entered into an employment agreement with Mr. Black. Mr. Black’s employment agreement provides for his employment at-will, and he may be terminated at any time by either party. Under his agreement, Mr. Black is entitled to a base salary to be determined annually by the

~~TABLE OF CONTENTS~~

Company’s Compensation Committee and is eligible for payment of an annual cash bonus, with a target amount equal to 125% of his base salary. Mr. Black’s employment agreement also specifies the payments and benefits to which he is entitled upon a termination of employment for specified reasons, which are discussed further below.

In connection with their offers of employment, the Company entered into letter agreements with each of Messrs. Convers, Brisendine and Anker. Under these letter agreements, each of Messrs. Convers, Brisendine and Anker is entitled to a base salary to be determined annually by the Compensation Committee and is eligible for payment of an annual cash bonus. The target annual cash bonus for Messrs. Convers, Brisendine and Anker is equal to 60% of his base salary, subject, in each case, to meeting performance goals set annually. The target cash bonus for Messrs. Convers, Brisendine and Anker of 60% of base salary for the 2018 Fiscal Year are consistent with the target cash bonuses for Fiscal Year 2017. In addition, each of Messrs. Brisendine, Guthrie, Convers and Anker has a severance agreement, which specifies the payments and benefits to which such executives are entitled upon a termination of employment for specified reasons, which are discussed further below.

~~Options Granted During 2015 under the Stock Incentive Plan~~

The Stock Incentive Plan and an employee stock option agreement govern each grant of stock options to our NEOs during the 2015 Fiscal Year and provide, among other things, the vesting provisions of the options and the option term. Options granted under the Stock Incentive Plan generally vest in five equal annual installments, subject to the recipient’s continued employment, and have a term of ten years. In the event an executive’s employment is terminated due to death or disability, the remaining options will immediately vest. In the case of a termination for “cause” (as defined in the Stock Incentive Plan), all of an executive’s options, whether vested or unvested, will be canceled effective upon the executive’s termination of employment. Following a termination of an executive’s employment other than for “cause,” vested options granted under the Stock Incentive Plan are canceled unless the executive exercises the options within 90 days (or 180 days if the termination was due to death, disability or retirement after age 65) or, if sooner, prior to the options’ normal expiration date. For more detail on the Stock Incentive Plan, see “— Determination of Executive Compensation — Long-Term Equity Incentives” on page 34.

~~Options and RSUs Granted During 2017, 2018 and 2019 under the Omnibus Incentive Plan~~

In the 2017 Fiscal Year, we began awarding RSUs as a vehicle to improve the balance and durability of our long-term incentive program. While we believe RSU grants are an effective retention incentive tool, we have historically maintained a 75% to 25% mix of options to RSUs in order to preserve our “pay for performance” environment and encourage continued growth. For the 2019 Fiscal Year, 25% of the long-term incentive compensation for our NEOs will consist of performance awards (“PSUs”), as discussed below, with options and RSUs representing the remaining 50% and 25%, respectively.

The Omnibus Incentive Plan and an award agreement govern the grant of stock options to Mr. Brisendine during the 2016 Fiscal Year and the grant of stock options and RSUs to each of our NEOs during the 2017, 2018 and 2019 Fiscal Years and provide, among other things, the vesting provisions and other terms. Options and RSUs under the Omnibus Incentive Plan generally vest in four equal annual installments, subject to the recipient’s continued employment, and have a term of ten years. In the event an executive’s employment is terminated other than for “cause” (as defined in the Omnibus Incentive Plan), a pro-rated amount of options and RSUs, as applicable, or in the case of retirement (subject to certain age and service conditions discussed below), the full amount of options and RSUs, as applicable, that would have vested at the next anniversary of the grant date (if any) would vest. Following a termination of an executive’s employment other than for “cause,” vested options under the Omnibus Incentive Plan are canceled unless the executive exercises the options (i) within 90 days, (ii) within one year if the termination was due to death or disability, (iii) within two years in case of retirement or, if sooner, (iv) prior to the options’ normal expiration date. In the case of a termination for “cause” (as defined in the Omnibus Incentive Plan), all of an executive’s options, whether vested or unvested, will be canceled effective upon the executive’s termination of employment.

During the 2016 Fiscal Year, the form of option agreement for future grants was revised (the “2016 Revised Option Agreement”) to provide for immediate vesting of unvested options if the executive’s employment is terminated due to death or disability. The 2016 Revised Option Agreement also provides that

~~TABLE OF CONTENTS~~

in the event of the executive’s retirement after attaining the age of 60 with ten years of service with the Company, subject to continued compliance with a non-competition agreement, the executive’s options continue to vest for one additional year following retirement. No options were granted to NEOs under the 2016 Revised Option Agreement during 2016, but the Company granted options under the 2016 Revised Option Agreement in February of 2017. During the 2018 Fiscal Year, the form of option agreement for future grants was revised (the “2018 Revised Option Agreement”) to provide that in the event of the executive’s retirement after attaining the age of 60 with ten years of service with the Company, subject to continued compliance with a non-competition agreement, the executive’s options continue to vest for two additional years following retirement. The Company granted options under the 2018 Revised Option Agreement in February 2018 and February 2019. The 2016 Revised Option Agreement and the 2018 Revised Option Agreement provide that options that were vested at the time of the executive’s retirement would be canceled unless the executive exercises the options within two years following retirement. Options granted under the 2016 Revised Option Agreement or the 2018 Revised Option Agreement that become vested during the one-year or two-year period following the executive’s retirement, as applicable, are canceled unless the executive exercises the options within two years following such options becoming vested. In all other material respects, the terms of options granted under the 2016 Revised Option Agreement and the 2018 Revised Option Agreement are the same as the terms of options granted in the 2016 Fiscal Year under the Omnibus Incentive Plan, discussed above.

The RSUs granted during the 2017 Fiscal Year contain similar vesting provisions as the 2016 Revised Option Agreement in the case of death, disability and retirement. The RSUs granted during the 2018 Fiscal Year and 2019 Fiscal Year contain similar vesting provisions as the 2018 Revised Option Agreement in the case of death, disability and retirement.

~~PSUs Granted During 2019 Fiscal Year under the Omnibus Incentive Plan~~

As noted above, in February 2019, we began awarding PSUs in order to further ensure that our executive compensation aligns with pay for performance and facilitates long-term stockholder value creation. The PSUs will be earned based upon the Company’s performance, over a three-year period, measured by pre-tax income plus amortization (“EBTA”) growth relative to a select peer group, subject to adjustment based upon the application of a return on invested capital (“ROIC”) modifier, as set forth below. The “Performance Period” for the PSUs is a three-year period commencing December 31, 2018 and ending January 2, 2022. Vesting of PSUs is contingent upon each NEO’s continued employment, subject to certain exceptions as set forth in the PSU agreement.

~~Potential Payments Upon Termination or Change in Control~~

~~Employment Agreement with Mr. Black~~

Mr. Black’s employment agreement specifies the payments and benefits to which he is entitled upon a termination of employment for specified reasons. Pursuant to his employment agreement, if Mr. Black’s employment is terminated without “cause,” or if he terminates his employment for “good reason,” he is entitled to receive (a) all salary, bonus and benefits earned but unpaid as of the date of termination,

~~TABLE OF CONTENTS~~

(b) severance pay consisting of 18 months of his base salary, (c) his bonus for the year in which his employment terminates based on actual results, (d) an additional amount equal to the bonus for the year in which his employment terminates based on actual results, prorated for the portion of the performance year that Mr. Black had remained employed and (e) continued medical, dental and vision insurance coverage for 18 months at active employee rates (on an after tax-basis). Severance will be paid in monthly installments, except that if Mr. Black is terminated within 12 months after a change in control then his severance will be paid in a lump sum. If Mr. Black is terminated for “cause,” or he voluntarily terminates his employment, or if Mr. Black’s employment is terminated due to death, he is only entitled to receive salary, bonus and benefits earned but unpaid as of the date of termination. If Mr. Black’s employment is terminated due to disability, he is entitled to receive (a) salary, bonus and benefits earned but unpaid as of the date of termination and (b) continued medical, dental and vision insurance coverage for 18 months at active employee rates. Any severance payments payable are conditioned upon to Mr. Black’s execution and non-revocation of a release.

Mr. Black’s severance arrangement operates with a “double trigger” in the event of a change of control, meaning severance payments do not occur unless his employment is involuntarily terminated (other than for cause or good reason) within 12 months following a change-in-control.

~~“Cause” is defined in the employment agreement as (i) conviction of, or plea of~~ ~~nolo contendere~~ to, a crime constituting a felony in the U.S. or a specified type of misdemeanor, (ii) willful or grossly negligent failure to perform material duties, (iii) willful material violation of company policy, (iv) material breach of a binding agreement to which he is a party and (v) willful conduct that materially and demonstrably harms the Company or any of its subsidiaries. Notice and cure provisions apply.

“Good Reason” is defined in the employment agreement as (i) a material reduction in base salary, (ii) a material reduction in annual incentive compensation opportunity, (iii) a material reduction in his authority, (iv) a transfer of the executive’s primary workplace to a location more than 50 miles from the Company’s headquarters (v) the failure to elect (or re-elect upon term expiration) him to the Board, the removal of Mr. Black from the Board or (vi) material breach by the Company or any of its subsidiaries of an agreement to which Mr. Black is the counterparty. Notice and cure provisions apply.

~~Separation Benefits Agreements with Messrs. Guthrie, Convers, Brisendine and Anker~~

The Company is party to a separation benefits agreement with each of Messrs. Guthrie, Convers, Brisendine and Anker that provide for certain severance benefits in the event of each executive’s termination of employment. Pursuant to the agreements, if the executive’s employment is terminated without “cause,” or if he terminates his employment for “good reason,” he is entitled to receive (a) all salary, bonus and benefits earned but unpaid as of the date of termination, (b) severance pay consisting of 18 months of his base salary, paid in monthly installments (except that if Mr. Brisendine is terminated within 12 months after a change in control then his severance will be paid in a lump sum), (c) an amount equal to his bonus for the year in which his employment terminates based on actual results, prorated for the portion of the performance year that the executive had remained employed, paid at the same time that the Company pays its executive annual bonuses for such fiscal year, and (d) continued medical, dental and vision insurance coverage for 18 months at active employee rates (on an after tax-basis). If the executive’s employment is terminated for “cause,” or the executive voluntarily terminates his employment without “good reason,” or if the executive’s employment is terminated due to death, he is only entitled to receive salary, bonus and benefits earned but unpaid as of the date of termination. If the executive’s employment is terminated due to disability, he is entitled to receive (a) salary, bonus and benefits earned but unpaid as of the date of termination and (b) continued medical, dental and vision insurance coverage for 18 months at active employee rates. Any severance payments payable are conditioned upon the executive’s execution and non-revocation of a release.

The severance arrangements for each of Messrs. Guthrie, Convers, Brisendine and Anker operate with a “double trigger” in the event of a change of control, meaning severance payments do not occur unless the his employment is involuntarily terminated (other than for cause or good reason) within 12 months following a change-in-control.

The definition of “Cause” in each separation benefit agreement is the same as the definition of “Cause” in Mr. Black’s employment agreement, which is described above under “— Employment Agreement with Mr. Black.”

~~TABLE OF CONTENTS~~

“Good Reason” is defined in the separation benefit agreement as (i) a reduction in base salary, (ii) a reduction in annual incentive compensation opportunity that is not offset with other increases in compensation, (iii) a material reduction in his authority, (iv) a material reduction in his aggregate welfare benefits, (v) a transfer of the executive’s primary workplace to a location more than 30 miles from the Company’s headquarters or (vi) material breach by the Company or any of its subsidiaries of an agreement to which the executive is the counterparty. Notice and cure provisions apply.

~~Accelerated Vesting of Options and RSUs on Certain Terminations of Employment or a Change in Control~~

~~Stock Incentive Plan~~. If a NEO’s employment is terminated as a result of the NEO’s death or disability, then the unvested options held by the NEO at the time of his or her death or disability will accelerate and become vested. Upon a termination for cause, all of the NEO’s options, whether vested or unvested, are forfeited. Upon a termination for any other reason, all unvested options will be forfeited.

If we undergo a “change in control,” as defined below, stock options granted under the Stock Incentive Plan will generally accelerate and be cancelled in exchange for a cash payment equal to the change in control price per share minus the exercise price of the applicable option, unless the Compensation Committee elects to provide for alternative awards in lieu of cancellation and payment.

~~Under the Stock Incentive Plan, a “change in control” is generally defined as the first to occur of the following events:~~

•

the acquisition by any person, entity or “group” (as defined in Section 13(d) of the Exchange Act) of more than 50% of the combined voting power of our then outstanding voting securities, other than any such acquisition by us, any of our subsidiaries, any employee benefit plan of ours or any of our subsidiaries, or any affiliates of any of the foregoing;

•

the merger, consolidation or other similar transaction involving us, as a result of which persons who were our stockholders immediately prior to such merger, consolidation, or other similar transaction do not, immediately thereafter, own, directly or indirectly, more than 50% of the combined voting power entitled to vote generally in the election of directors of the merged or consolidated company;

•

within any 12-month period, the persons who were our directors at the beginning of such period (called “incumbent directors”) cease to constitute at least a majority of the Board, except that any director elected or nominated for election to the Board by a majority of the incumbent directors then still in office is deemed to be an incumbent director for these purposes; or

•

the sale, transfer or other disposition of all or substantially all of our assets to one or more persons or entities that are not, immediately prior to such sale, transfer or other disposition, affiliates of ours.

~~Omnibus Incentive Plan.~~ For the options and RSUs granted in 2017 and 2018 under the Omnibus Incentive Plan, if a NEO’s employment is terminated as a result of the NEO’s death or disability, then all unvested options and RSUs held by the NEO at the time of his or her death or disability will accelerate and become vested. If a NEO resigns or retires at or after the age of 60, and has been an employee of the Company for at least 10 years, subject to certain non-competition requirements, then unvested options and RSUs will continue to vest on the prescheduled vesting dates in the one-year period following the effective date of such resignation or retirement (in the case of options and RSUs granted in 2017), or the two-year period following the effective date of such resignation or retirement (in the case of options and RSUs granted in 2018). Upon a termination without cause, unvested options and RSUs will vest in an amount equal to the number of options and RSUs, as applicable, that would have vested on the next scheduled vesting date, had he remained employed through such vesting date, multiplied by a fraction, (x~~) the numerator of which is the number of days from the immediately preceding vesting date (or the grant date, if the termination of employment occurs prior to the first vesting date) and (~~y) the denominator is the number of days from the immediately preceding vesting date (or the grant date, if the termination of employment occurs prior to the first vesting date) through such next vesting date.

~~TABLE OF CONTENTS~~

For the options granted in 2016 under the Omnibus Incentive Plan, in the event of the NEO’s termination of employment by reason of death, disability or retirement, or upon a termination without cause, unvested options will vest in an amount equal to the number of options that would have vested on the next scheduled vesting date, had he remained employed through such vesting date, multiplied by a fraction, (x~~) the numerator of which is the number of days from the immediately preceding vesting date (or the grant date, if the termination of employment occurs prior to the first vesting date) and (~~y) the denominator is the number of days from the immediately preceding vesting date (or the grant date, if the termination of employment occurs prior to the first vesting date) through such next vesting date.

If we undergo a “change in control,” as defined below, no vesting or cancellation of awards granted under the Omnibus Incentive Plan will occur if awards are assumed and/or replaced in the change in control with substitute awards having the same or better terms and conditions, provided that any substitute awards must fully vest on a participant’s involuntary termination of employment without “cause” or voluntary termination with “good reason,” in each case occurring within one year following the date of the change in control. If the Compensation Committee determines that substitute awards will not be provided in the change in control, all outstanding awards would fully vest and be cancelled for the same per share payment made to the stockholders in the change in control (less, in the case of options and SARs, the applicable exercise or base price). The Compensation Committee has the ability to prescribe different treatment of awards in the award agreements.

~~Under the Omnibus Incentive Plan, a “change in control” is generally defined as the first to occur of the following events:~~

•

any transaction that results in the acquisition by any person, entity or “group” (as defined in Section 13(d) of the Exchange Act) of more than 50% of the combined voting power of our then outstanding voting securities, other than any such acquisition by us, any of our subsidiaries, any employee benefit plan of ours or any of our subsidiaries, or any affiliates of any of the foregoing;

•

~~Our initial public offering did not constitute a change in control for purposes of the equity plans.~~

~~Summary of Potential Payments Upon Termination of Employment or Upon the Occurrence of a Change in Control~~

The following table shows the estimated value of benefits to Messrs. Black, Guthrie, Convers, Brisendine and Anker if their employment had been terminated under the various circumstances described below as of December 28, 2018, the last business day of the 2018 fiscal year, or upon the occurrence of a change in control. The amounts shown in the table exclude accrued but unpaid base salary, unreimbursed employment-related expenses, accrued but unpaid vacation pay (which payments and reimbursements would be made to all salaried associates), distributions under our 401(k) retirement plan (which plan is generally available to all of our salaried associates), and the value of equity awards that were vested by their terms as of December 28, 2018. For a description of the definition of “cause” and the timing of the payments see “Potential Payments Upon Termination or Change in Control — Employment Agreement with Mr. Black” on page 42 ~~and “Potential Payments Upon Termination or Change in Control — Separation Benefits Agreements with Messrs. Guthrie, Convers, Brisendine and Anker” on page~~ 43.

~~Director Compensation~~

In connection with our initial public offering, the Board adopted a non-employee director compensation policy that is designed to provide a total compensation package that enables us to attract and retain, on a long-term basis, high-caliber non-employee directors. In May 2018, the Board amended and restated the policy to increase the cash retainer and annual equity portions by $10,000 each as a result of a market benchmarking survey conducted by Pearl Meyer. Under this policy, all non-employee directors are entitled to cash compensation as set forth below, payable in arrears on a quarterly basis:

Annual Retainer
Board:
All non-employee members $ 60,000
Lead Director $ 35,000
Audit Committee:
Chair $ 25,000
Non-Chair members $ 12,500
Compensation Committee:
Chair $ 20,000
Non-Chair members $ 10,000
Nominating and Corporate Governance Committee:
Chair $ 15,000
Non-Chair members $ 7,500

Each non-employee director has the right to elect to receive all or a portion of his or her annual cash retainer in the form of fully-vested deferred stock units using the fair market value of a share of the Company’s common stock on the payment date subject to deferral requirements of Section 409A of the Internal Revenue Code of 1986, as amended.

Under the policy, on the date of each annual meeting of our stockholders, each continuing non-employee director is eligible to receive a prospective equity award for the coming year of service with a grant date fair value of $90,000 in the form of fully vested deferred stock units (“DSUs”). The DSUs are granted to our non-employee directors under the Omnibus Incentive Plan on a fully vested basis but will not settle into the Company’s common stock until after the director receiving the grant has ceased to serve as a non-employee director on the Board or a change in control.

~~We have also agreed to reimburse all reasonable out-of-pocket expenses incurred by non-employee directors in attending Board and committee meetings.~~

~~Director Compensation for 2018 Fiscal Year~~

Mr. Diaz elected to receive 100% of his cash compensation in the form of DSUs and, accordingly, received 890 DSUs, as payment in lieu of his cash compensation. Mr. Pressler assigned all of his DSUs to Clayton, Dubilier & Rice, LLC, our former equity sponsor.

The grant date fair value of the DSUs is computed in accordance with FASB ASC Topic 718, modified to exclude any forfeiture assumptions related to service-based vesting conditions, determined by dividing the grant value by the closing price of our common stock on the grant date.

~~Compensation Committee Interlocks and Insider Participation~~

Messrs. Dunbar and Diaz and Ms. Isbell and former director Mr. Grebe all served as members of the Compensation Committee during the 2018 Fiscal Year. No member of the Compensation Committee during the 2018 Fiscal Year is or at any time has been an officer or employee of the Company or any of its subsidiaries. None of our executive officers serves or has served on the compensation committee or the board of directors of another entity which had an executive officer serving on the Compensation Committee during the 2018 Fiscal Year.

~~Includes 1,508,345 stock options, 28,708 RSUs and 25,042 DSUs granted to officers and directors pursuant to the Omnibus Incentive Plan and the Stock Incentive Plan.~~

~~CEO Pay Ratio~~

For the 2018 Fiscal Year: (i) the total compensation of our median employee (excluding Mr. Black, our CEO) was $49,950; and (ii) the annual total compensation of Mr. Black, our CEO, was $3,516,748. Based on this information, the ratio of the annual total compensation of our CEO to the median employee is 70.4 to 1.

~~Methodology~~

During the 2018 Fiscal Year, there were no changes to our employee population or employee compensation arrangements that we believe would result in significant changes to our pay ratio disclosure compared to the disclosure in our Proxy Statement delivered in connection with our 2018 annual meeting of stockholders. Accordingly, pursuant to SEC rules, we are using the same median employee as last year for purposes of our pay ratio disclosure. To identify the median employee last year, as well as to determine the annual total compensation of such median employee, we used our total employee population as of October 31, 2017, which consisted of a total of 3,448 individuals, 3,399 of whom were located in the United States and 49 of whom were located in Canada.

~~Compensation Measure~~

~~We use a variety of pay elements to structure the compensation arrangements of our employees, including an annual cash bonus plan for a portion of our full-time employees, commissioned-based~~

~~TABLE OF CONTENTS~~

~~incentive compensation for employees in our various sales organizations, and hourly compensation for those employees who are not eligible to receive incentive compensation.~~

Consequently, for purposes of identifying the median compensated employee, we used the annualized pay rate for both our hourly and salary associates active as of October 31, 2017. We included all permanent employees, including new employees who were hired in fiscal 2017 but did not work for the company for the entire fiscal year. For our Canadian employees, we converted their local CAD to USD using the 2017 annual exchange rate of 1.2573. We did not make any cost-of-living adjustments in identifying the median employee.

Using this methodology, we determined that our median employee was a full-time, salaried employee located in the United States. Using the same methodology we used in calculating Mr. Black’s annual total compensation, for Fiscal Year 2018, the total annual compensation of the median employee was $49,950.

~~With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of our 2018 Summary Compensation Table on page 38.~~

PROPOSAL 4:3: RATIFICATION OF SELECTION OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Deloitte & Touche LLP (“Deloitte”) audited our consolidated financial statements for the ~~fiscal year ended December 30, 2018.~~2023 Fiscal Year. As discussed below, our Audit Committee, which has sole and direct responsibility for the appointment, compensation, oversight, evaluation, retention and termination of any independent registered public accounting firm engaged by the Company, considers Deloitte ~~& Touche~~ to be well qualified and has appointed Deloitte ~~& Touche~~ as our independent registered public accounting firm to audit our consolidated financial statements for the ~~year ending December 29, 2019.~~2024 Fiscal Year.

This proposal asks you to ratify the Audit Committee’s appointment of Deloitte ~~& Touche~~ as our independent registered public accounting firm. Although we are not required to obtain such ratification from our stockholders, the Board believes it is a sound corporate governance practice to do so.

As in prior years, the Audit Committee, along with senior management and the Company’s internal auditor, reviewed ~~Deloitte & Touche’s 2018~~Deloitte’s performance as part of its consideration of whether to re-appoint Deloitte ~~& Touche~~ as our independent registered public accounting firm. As part of this review, the Audit Committee considered, among other things:

•

~~the length of time that Deloitte & Touche has served as our independent registered accounting firm;~~Deloitte’s independence and objectivity;

•

the communication and interaction with our Deloitte team over the course of the prior year, the breadth and complexity of our business and its national footprint and the resulting demands placed on the auditing firm;

•

external data and management’s perception relating to the depth and breadth of ~~Deloitte & Touche’s~~Deloitte’s auditing qualification and experience;

•

Deloitte’s historical and recent performance;

•

recent Public Company Accounting Oversight Board (United States) (“PCAOB”) inspection reports on the firm;

•

the length of time that Deloitte has served as our independent registered accounting firm;

•

the quantity and quality of ~~Deloitte & Touche’s~~Deloitte’s staff and national reach;

•

the ~~communication~~appropriateness of Deloitte’s fees; and ~~interaction with our Deloitte & Touche team over the course of the prior year; and~~

•

the potential impact of changing our independent registered public accounting firm.

The Audit Committee recognized the ability of Deloitte ~~& Touche~~ to provide both the necessary expertise to audit our business and the matching national footprint to audit the Company nationwide, as well as other factors, including the policies that Deloitte ~~& Touche~~ follows with respect to the rotation of its key audit personnel so that there is a new partner-in-charge at least every five years. The Audit Committee is involved in the selection of the new partner-in-charge of the audit engagement when there is a rotation.

Based on the results of its review, the Audit Committee concluded that Deloitte ~~& Touche~~ is independent and objective and that it is in the best interests of the Company and its stockholders to appoint Deloitte ~~& Touche~~ to serve as the Company’s independent registered accounting firm for ~~2019.~~the 2024 Fiscal Year. Consequently, the Audit Committee has appointed Deloitte ~~& Touche~~ as the Company’s independent registered public accounting firm for ~~2019,~~the 2024 Fiscal Year, and the Board is recommending that the Company’s stockholders ratify this appointment.

If the Company’s stockholders do not ratify the selection, the Audit Committee will reconsider whether or not to retain Deloitte ~~& Touche~~ but may, nonetheless, choose to retain Deloitte ~~& Touche~~ as the Company’s independent registered public accounting firm. Even if the selection is ratified, the Audit Committee in its discretion may change the appointment at any time if it determines that such change would be in the best interests of the Company and its stockholders.

A representative of Deloitte ~~& Touche~~ is expected to be present at the Annual Meeting, will have the opportunity to make a statement and is expected to be available to respond to appropriate questions by stockholders.

The sections below provide information relevant to the Audit Committee’s selection of ~~Deloitte & Touche.~~Deloitte.

~~(4)~~

“All other ~~fees~~fees” are fees for any products and services provided by Deloitte ~~& Touche~~ not included in the first ~~three~~two categories.

Audit Committee Pre-Approval Policies and Procedures

The Audit Committee charter provides that the Audit Committee has the sole authority and responsibility to pre-approve all audit and non-audit services to be performed for the Company by its independent registered public accounting firm and the related fees. Audit Committee pre-approval is required in order to help assure that the services provided by the independent registered public accounting firm do not impair the registered public accounting firm’s independence from the Company.

In compliance with rules of the SEC and the ~~Public Company Accounting Oversight Board (United States) (“PCAOB”),~~PCAOB, the Audit Committee has established a pre-approval policy that requires the pre-approval of all services to be performed by the independent registered public accounting firm. Services provided by the independent registered public accounting firm must be approved by the Audit Committee on a ~~case by case~~case-by-case basis unless such services fall within a detailed list of pre-approved audit, audit-related, and tax services, and related fee limitations set forth in the pre-approval policy. The Audit Committee may also grant pre-approval to those permissible non-audit services classified as all other services that it believes are routine or recurring services and would not impair the independence of the independent registered public accounting firm. The independent registered public accounting firm may be considered for other services not specifically approved as audit, audit-related, and tax services so long as the services are not prohibited by SEC or PCAOB rules and would not otherwise impair the independence of the independent registered public accounting firm.

All of the services performed by Deloitte ~~& Touche~~ during ~~2018~~the 2023 Fiscal Year and ~~2017~~the 2022 Fiscal Year were approved in advance by the Audit Committee pursuant to the pre-approval policy.

PROPOSAL 4: ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

We provide our stockholders with the opportunity to cast an advisory vote to approve the compensation of our NEOs. This non-binding advisory vote, commonly known as a “say on pay” vote, gives our stockholders the opportunity to express their views on our NEOs’ compensation on an annual basis. This vote is not intended to address any specific item of compensation but rather the overall compensation of our NEOs and the philosophy, policies and practices described in this Proxy Statement. Since our IPO, we have received strong “say on pay” support, including more than 93% “say on pay” support at last year’s 2023 Annual Meeting of Stockholders.

The Board and Human Resources and Compensation Committee are dedicated to ensuring that our executive officers are compensated competitively with the market and consistently with our business strategy, sound corporate governance principles and stockholder interests and concerns. To do so, the Human Resources and Compensation Committee uses a combination of short- and long-term incentive compensation, including performance-based awards, to motivate and reward executives who can significantly influence our long-term financial success and who are responsible for effectively managing our operations in a way that maximizes stockholder value.

We believe that our compensation program is effective in achieving our goals, has contributed to the Company’s success and is strongly aligned with the long-term interests of our stockholders and that the total compensation packages provided to our NEOs are reasonable. For these reasons, the Board is asking stockholders to vote “FOR” the following resolution:

As you consider this proposal, we urge you to read the “Compensation Discussion and Analysis” section of this Proxy Statement on page 34 for additional details on our executive compensation, including the more detailed information regarding our compensation philosophy and objectives.

As an advisory vote, this proposal is not binding on the Board or the Human Resources and Compensation Committee, will not overrule any decisions made by the Board or the Human Resources and Compensation Committee or require the Board or the Human Resources and Compensation Committee to take any specific action. Although the vote is non-binding, the Board and the Human Resources and Compensation Committee value the opinions of our stockholders and will carefully consider the outcome of the vote when making future compensation decisions for our NEOs.

Required Vote

Approval of the compensation of our NEOs as presented in this Proxy Statement requires the affirmative vote of a majority of the shares present, either in person or by proxy, at the Annual Meeting.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS PRESENTED IN THIS PROXY STATEMENT.

Compensation Philosophy and Objectives

•

To pay for performance.

•

To reward our executives with equity in the Company in order to align their interests with the interests of our stockholders and allow our executives to share in our stockholders’ success.

•

To create a performance culture and maintain morale, which we believe drives exceptional customer service and safety performance.

•

To enable us to attract, motivate and retain top executive talent.

At last year’s 2023 Annual Meeting of Stockholders, our executive compensation program received strong stockholder support, with more than 93% of votes cast in favor of the compensation of our NEOs. We value the opinions of our stockholders, and the Human Resources and Compensation Committee carefully considers the feedback it receives. Accordingly, the Human Resources and Compensation Committee will continue to consider the outcome of our say-on-pay votes and our stockholders’ views when making future compensation decisions.

2024 Incentive Plan Design Changes

For the 2024 Fiscal Year, the Human Resources and Compensation Committee approved changes to the award mix for our NEOs under the LTIP, which will consist of 50% RSUs and 50% PSUs. We believe this update to the award mix under our LTIP further demonstrates our commitment to designing an executive compensation program that encourages high performance and results that will create value for us and our stockholders while avoiding unnecessary risks. The Human Resources and Compensation Committee retained the existing vesting and performance conditions for the RSUs and PSUs.

For the 2024 Fiscal Year, the Human Resources and Compensation Committee also approved modest changes to the customer-centric metric in our Short-Term Annual Incentive Plan. We retained the use of Company Net Promoter Score (“Company NPS”) and added metrics related to customer retention and per-customer value. We believe these updates capture a broader view of our customer relationships with a goal of maintaining our strong reputation, and retaining and deepening our relationships with our existing customers. The Human Resources and Compensation Committee retained the other metrics and weightings for the balance of our Short-Term Annual Incentive Plan.

2023 Business Highlights

	Net Sales			$4.30 billion, up 7% from 2022
	Customer Net Promoter Score			84.9, up from 78.9 in 2022
	Safety – Lost Time Incident Rate			0.21, down 49% from 2022

2023 Compensation Highlights

2023 Base Salaries

For 2023, the Human Resources and Compensation Committee approved salary increases for our NEOs ranging from 4.1% to 5.7% based on external factors, including competitive market data, retention considerations and internal factors such as personal performance, experience, and the significance of the role to the Company. Adjustments generally positioned our NEOs near the 50th percentile of market.

2023 Bonus Payments

Our NEOs earned bonuses ranging from 70% to 78% of the target award. Our 2023 annual cash bonus plan included three financial metrics: Adjusted EBITDA (weighted 70%), Company NPS (weighted 5%), Organic Daily Sales Growth (weighted 5%), as well as individual strategic goals (weighted 20%, with 2-3 goals per NEO). Each metric provided for a maximum payout of 250% (EBITDA) or 150% (All Other) of target, a target payout of 100%, and a threshold payout of 50% of target, with zero payout for performance below the threshold level. We achieved above threshold performance for Adjusted EBITDA and Organic Daily Sales Growth, near maximum for Company NPS, and between target and maximum for individual strategic goals.

2021 Performance Stock Unit Award Payouts

In early 2021, PSUs were granted contingent on three-year performance based on our earnings before taxes and amortization (“EBTA”) growth relative to a performance peer group, modified by our return on invested capital (“ROIC”), with a maximum potential payout of 200% of target. The Human Resources and Compensation Committee will review and certify the actual payout in May 2024 after it can assess our performance versus the peer group, which includes our then-current compensation peer group plus other best-in-class distributors viewed as having comparable business models.

Determination of Executive Compensation

Human Resources and Compensation Committee

The Human Resources and Compensation Committee is responsible for reviewing and approving the compensation and benefits of our executives (including our NEOs), directors and certain consultants, approving equity incentive compensation and other incentive arrangements and approving employment and related agreements. In performing these duties, the Human Resources and Compensation Committee is supported by its independent consultant and certain members of executive management, as described below.

Independent Consultant

For the 2023 Fiscal Year, the Human Resources and Compensation Committee engaged FW Cook as its independent consultant. FW Cook reports to and is directed by the Human Resources and Compensation Committee and provides no other services to the Company. The Human Resources and Compensation Committee considered the independence of FW Cook in light of applicable SEC rules and NYSE listing standards and concluded that FW Cook was appropriately independent and free from potential conflicts of interest.

Industry Peer Group

To assist in evaluating our compensation program for 2023, in August 2022, the Human Resources and Compensation Committee reviewed our Company’s industry peer group, considering among other factors, total market capitalization and revenue, and whether the peer is a company with which we compete for talent and/or has a similar business model. At that time, the Human Resources and Compensation Committee approved the removal of DXP Enterprises, Inc. and H&E Equipment Services, Inc. (as both were considered less relevant as peers considering their smaller size relative to SiteOne and the other peer companies) to maintain a robust sample size and position the Company within a reasonable range of median in various measures of company size. The

Use of Market Data

The Human Resources and Compensation Committee reviews competitive market data from our industry peer group and general industry surveys as part of its process to set the target pay opportunities for our NEOs. Our executive compensation program aims to provide for total compensation for our executives at approximately the 50th percentile of our peer group, with flexibility to position an individual executive above or below the 50thpercentile based on factors including, but not limited to, contribution, performance and uniqueness of role.

Executive Management

Certain members of the executive management team are involved in the executive compensation determination process. For example, our Executive Vice President, Human Resources provides requested information and perspectives on the compensation program, and our General Counsel provides legal and regulatory advice and perspectives. In addition, our CEO makes specific recommendations for compensation levels and program designs for executives (other than himself) and our Chief Financial Officer provides input on financial metrics and goals. Our CEO, Executive Vice President, Human Resources and General Counsel generally attend Human Resources and Compensation Committee meetings but are excused when their individual compensation is being discussed.

Elements of Our Executive Compensation Program

To create a “pay-for-performance” environment, compensation is weighted toward at-risk compensation, consisting of salary, short-term annual cash incentive compensation, long-term equity incentive compensation and certain other benefits. Our base salaries provide a fixed level of compensation, our short-term annual cash incentive program rewards achievement of key financial and strategic objectives, and our long-term incentive opportunities tie a large portion of our NEOs’ total compensation to Company performance and long-term stock growth. Our short-term annual cash incentive program includes Adjusted EBITDA, Company NPS, Organic Daily Sales Growth and other individualized strategic performance targets. The Adjusted EBITDA component of our short-term annual cash incentives, which represents 70% of the incentive opportunity, is capped at 250% of target, and each additional component, which collectively represent the remaining 30% of the incentive opportunity, is capped at 150% of target. Our long-term equity incentive program provides for extended vesting schedules and includes PSUs with three-year relative and absolute performance criteria and capped payouts at 200% of target. Lastly, we provide other benefits as discussed below.

Set forth below is a chart outlining each element of our compensation program for our executive officers and the objectives of each component, and the key measures used in determining each component. For the 2023 Fiscal Year, each NEO’s target total direct compensation, which includes base salary, target short-term annual

cash incentives and long-term equity incentives, approximated the median (i.e., 50th percentile) of competitive market data compiled by FW Cook.

Pay Component			Objective of Pay Component
Base Salary			• To attract and retain a high-performing leadership team
Short-Term Annual Cash Incentives			• To reward achievement of short-term business objectives and results, and individual performance goals viewed as drivers of stockholder value
Long-Term Equity Incentives			• To align executive and stockholder interests, create “ownership culture,” promote retention and “pay-for-performance”
Other Benefits			• To provide a safety net of protection in the case of illness, disability, death or retirement, through health, disability and life insurance, 401(k) retirement plan and other employee benefits

Base Salary

Base salaries are set to attract and retain high-performing executive talent. The determination of each executive’s base salary is based on personal performance, experience in the role, competitive rates of pay for comparable roles, significance of the role to the Company, the availability of potential replacement executives and anticipated economic conditions. Each year, the Human Resources and Compensation Committee considers merit and market-based salary increases, using data from our peer group, for our executives, including our NEOs. Based on these factors, in February 2023, the Human Resources and Compensation Committee approved salary increases for each of our NEOs in the range of 4.1% to 5.7%, which generally positioned salaries near the 50th percentile of market. The salary increases for our NEOs took effect on February 20, 2023. The base salaries approved by the Human Resources and Compensation Committee for each NEO during the 2022 Fiscal Year and 2023 Fiscal Year are shown below.

	2022 Base Salary			2023 Base Salary			Base Salary Increase
Doug Black		$	875,000		$	925,000		5.7%
John Guthrie		$	500,000		$	525,000		5.0%
Briley Brisendine		$	470,000		$	490,000		4.3%
Scott Salmon		$	420,000		$	440,000		4.8%
Joseph Ketter		$	370,000		$	385,000		4.1%

Short-Term Annual Cash Incentives

Our short-term annual cash incentives are designed to focus our NEOs on achieving superior performance against business objectives and results for the Company as a whole and, in addition, reward them for the achievement of specific individual performance and/or other goals which the Human Resources and Compensation Committee and CEO (in the case of NEOs other than himself) subjectively determine based on their assessment of the executive’s performance during the year. By conditioning a significant portion of our NEOs’ potential total cash compensation on the Company’s achievement of clearly defined metrics and goals, we reinforce our focus on creating a strong pay-for-performance culture.

For the 2023 Fiscal Year, all of our NEOs were eligible to receive short-term annual cash incentives based on the achievement of pre-established annual Company financial and performance metrics and goals approved by the Human Resources and Compensation Committee. Each NEO had a target incentive opportunity expressed as

a percentage of his base salary paid during the year. The threshold, target and maximum percentages of base salary and actual percentages of target for our NEOs for the 2023 Fiscal Year were as follows:

	Threshold(1)		Target(1)		Maximum(1)
Doug Black		62.5%		125%		275%
John Guthrie		30%		60%		132%

Expressed as a percentage of base salary. For the 2023 Fiscal Year, each of the various components of the annual incentive awards were subject to a cap, as set forth below.

The Human Resources and Compensation Committee selected Adjusted EBITDA as the primary financial performance metric for our NEOs’ short-term annual cash incentive opportunity, measured against the Adjusted EBITDA goals established by the Human Resources and Compensation Committee in the beginning of the 2023 Fiscal Year and increased mid-year for acquisitions completed prior to the Human Resources and Compensation Committee’s August 8, 2023 meeting. The Human Resources and Compensation Committee reviewed the Company’s 2023 Fiscal Year outlook in establishing the initial Adjusted EBITDA target range, noting that 2023 results were projected to fall below 2022 Fiscal Year actual results given margin contraction from higher input costs that had already materialized with respect to fourth quarter results for the 2022 Fiscal Year. However, the Human Resources and Compensation Committee determined to set our initial Adjusted EBITDA target range at $450 – 464 million, with the high end of that range equal to our record-setting 2022 Fiscal Year results. The Human Resources and Compensation Committee set the target based on its judgment that the Company needed to exceed prior year performance to merit an above-target payout. Subsequently, in order to mitigate the impact of acquisitions not reflected in the levels of achievement for the Adjusted EBITDA performance metric originally approved by the Human Resources and Compensation Committee in February 2023, in August 2023, the Human Resources and Compensation Committee increased the threshold, target and stretch goals to take into account anticipated Adjusted EBITDA contributions from acquisitions completed prior to the Human Resources and Compensation Committee’s August 8, 2023 meeting. If actual performance fell within the Adjusted EBITDA target range, then the payout is at target for such metric. To ensure our Company continues to deliver outstanding customer service, the Human Resources and Compensation Committee also utilized Company NPS as a component of each NEO’s short-term annual cash incentive. In addition, to drive continued sales growth, the Human Resources and Compensation Committee also utilized Organic Daily Sales Growth as a component of our NEOs’ short-term annual cash incentives. The Human Resources and Compensation Committee subjectively assessed Mr. Black’s achievement for the strategic performance goals, and for the other NEOs, Mr. Black evaluated the performance of each NEO based on his individual strategic performance goals and made a recommendation to the Human Resources and Compensation Committee. The following table shows the weighting of the 2023 Fiscal Year performance metrics for each NEO, expressed as a percentage of each NEO’s 2023 Fiscal Year total short-term annual cash incentive opportunity.

(1)

Adjusted EBITDA was calculated using EBITDA for the Company for the 2023 Fiscal Year, as further adjusted for items such as stock-based compensation expense, (gain) loss on sale of assets, financing fees, acquisitions and other adjustments. See Appendix A to this Proxy Statement for a reconciliation of Adjusted EBITDA to Net income (loss), the corresponding GAAP financial measure.

(2)

Acquisitions completed after the Human Resources and Compensation Committee’s August 8, 2023 meeting were excluded from the calculation of Adjusted EBITDA for purposes of determining short-term annual cash incentive compensation.

(3)

The Adjusted EBITDA weighted performance multiplier is determined by linear interpolation of the percentage achievement between threshold and target goals, between target and stretch and between stretch and max goals.

The following table shows the threshold, target, maximum and actual performance levels, along with the multiple of target incentive opportunity, for the Company NPS component of the 2023 Fiscal Year short-term annual cash incentive opportunities for our NEOs.

Company NPS(1)	Level of Achievement(2)		Payout as % of Target Opportunity
Threshold		72		50%
Target		80		100%
Maximum		85		150%
Actual		84.9		149%

(1)

Company NPS is based on responses from a customer survey regarding customer experience. Respondents to the survey are categorized as detractors (0-6 score for likelihood to recommend), passives (7-8) and promoters (9-10). Company NPS is then calculated by subtracting the percentage of detractors from the percentage of promoters.

(2)

The Company NPS weighted performance multiplier is determined by linear interpolation of the percentage achievement between threshold and target goals and between target and max goals.

The following table shows the threshold, target, maximum and actual performance levels, along with the multiple of target incentive opportunity, for the Organic Daily Sales Growth component of the 2023 Fiscal Year incentive opportunities for our NEOs.

Threshold		0%		50%
Target		5%		100%
Maximum		7%		150%
Actual		0.2%		52%

“Organic Daily Sales” refers to Organic Sales in the fiscal reporting period divided by the number of business days, excluding Saturdays, Sundays and holidays, that our branches are open during such relevant fiscal reporting period. “Organic Sales” is defined as all sales, including sales from newly-opened greenfield branches and decreases in sales from closing existing branches, but excluding any sales from acquired branches until they have been under our ownership for at least four full fiscal quarters at the start of the fiscal reporting period. Organic Daily Sales is a non-GAAP financial measure. Reconciliation to the corresponding GAAP financial measure can be found in Appendix A to this Proxy Statement.

The Organic Daily Sales weighted performance multiplier is determined by linear interpolation of the percentage achievement between threshold and target goals and between target and max goals.

To determine the level of achievement of the NEOs’ individual strategic performance criteria, the Human Resources and Compensation Committee subjectively assessed Mr. Black’s achievement and, with respect to the other NEOs, Mr. Black evaluated the performance of each NEO based on their individual strategic performance measures and made a recommendation to the Human Resources and Compensation Committee with respect to each NEO’s level of achievement. The individual criteria related to specific individual categories of performance measures, level of achievement and factors supporting such level of achievement are set forth below.

Eligible earnings reflect the actual base salaries earned by each NEO during the 2023 Fiscal Year.

The award paid to each of our NEOs is also shown in the “Summary Compensation Table” on page 47 under the “Non-Equity Incentive Plan Compensation” column.

Long-Term Equity Incentives

The Human Resources and Compensation Committee makes annual equity grants to our executives as part of our compensation program under our 2020 Omnibus Equity Incentive Plan (the “2020 Plan”). In addition, the Human Resources and Compensation Committee may, from time to time, provide an equity award to one or more of our NEOs to retain and reward key talent or to reflect increased responsibilities. No such equity awards were made during 2023. The Human Resources and Compensation Committee may also review and approve equity awards for promotions. For more information regarding the equity awards granted to our NEOs under the 2020 Plan during the 2023 Fiscal Year, see the “Grants of Plan-Based Awards for 2023 Fiscal Year” table on page 48.

Awards Granted During 2023 under the 2020 Plan

To support our “pay-for-performance” culture, compensation is weighted toward at-risk compensation. Our long-term equity incentive program, which consisted of approximately 33% stock options, 33% RSUs and 33% PSUs for the 2023 Fiscal Year, is designed to serve stockholders’ best interests through sustained long-term financial and stock price performance.

TABLE OF CONTENTS

In connection with its annual review of our executive compensation program, including input from FW Cook and feedback received from our stockholders during the 2023 Fiscal Year, in February 2024, our Human Resources and Compensation Committee approved an award mix for our NEOs under the LTIP consisting of 50% RSUs and 50% PSUs for the 2024 Fiscal Year. We believe this update to the award mix under our LTIP further demonstrates our commitment to designing an executive compensation program that encourages high performance and results that will create value for us and our stockholders while avoiding unnecessary risks. We also believe this updated LTIP design evidences our responsiveness to stockholder feedback to enhance the alignment of our executives’ interests with our stockholder interests and allow our executives to share in our stockholders’ success.

The table below sets forth the number of stock options, RSUs and PSUs awarded to each NEO in the 2023 Fiscal Year:

Name	Number of Options Awarded		Number of RSUs Awarded		Number of PSUs Awarded		Targeted Fair Value for All 2023 Awards

Performance Stock Units

PSUs are earned based upon the Company’s performance, over a three-year period, measured by pre-tax income plus amortization (“EBTA”) growth relative to a select peer group, subject to adjustment based upon the application of a ROIC modifier, as set forth below. The “Performance Period” for the PSUs awarded in February 2023 is a three-year period commencing January 2, 2023 and ending December 28, 2025. The Performance Period for the PSUs awarded in February 2022 is a three-year period commencing January 3, 2022 and ending December 29, 2024. The Performance Period for the PSUs awarded in February 2021 is a three-year period commencing January 4, 2021 and ending December 31, 2023. Vesting of PSUs is contingent upon each NEO’s continued employment, subject to certain exceptions as set forth in the PSU agreement.

The value of the earned PSUs was based on our closing stock price ($148.09) on May 11, 2023.

The benefits provided to our NEOs are generally the same as those provided to our other salaried associates and include, but are not limited to, medical, dental, health, accident, hospitalization and disability insurance, and a tax-qualified 401(k) plan. In addition, NEOs receive company-paid life insurance benefits of 2X base salary.

Tax and Accounting Considerations

The Human Resources and Compensation Committee and management have taken into account the accounting and tax impact, including Section 162(m) (“Section 162(m)”) of the Internal Revenue Code, of various program designs to balance the potential cost to us with the value to the executive. Section 162(m), as most recently amended in December 2017 in connection with tax reform legislation, limits the deductibility of compensation paid to “covered employees” in excess of $1,000,000 in any taxable year. While the Human Resources and Compensation Committee may consider the impacts of Section 162(m) when determining executive compensation, it may authorize compensation payments that do not comply with the exemptions in Section 162(m) when it believes that such payments are appropriate to attract and retain executive talent.

The Human Resources and Compensation Committee and management also consider the accounting implications of our executive officer compensation program. The expenses associated with executive compensation issued to our executive officers and other key associates are reflected in our financial statements. We account for stock-based compensation programs in accordance with the requirements of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718, Compensation-Stock Compensation, which requires companies to recognize in the income statement the grant date value of equity-based compensation issued to associates over the vesting period of such awards.

Executive Officer Stock Ownership and Retention Guidelines

The Company has established stock ownership and retention guidelines in order to further align the long-term interests of our executive officers with those of our stockholders. Our stock ownership guidelines limit the ability of our CEO and each Covered Executive from selling shares of the Company’s common stock unless they own shares having an aggregate value equal to a multiple of annual base salary, as follows:

Position			Multiple
Chief Executive Officer			6x Annual Base Salary
Covered Executives			2x Annual Base Salary

Only shares held directly by the individual count for purposes of ownership under the stock ownership guidelines.

The CEO and each Covered Executive is required to hold 50% of shares acquired as a result of any settlement of compensatory awards (net of any shares withheld for taxes and the exercise price of stock options) until ownership guidelines have been met. Currently, our CEO and each Covered Executive is in compliance with the Executive Officer Stock Ownership and Retention Guidelines.

We have also established stock ownership requirements for our non-employee directors. See “Director Compensation — Non-Employee Director Stock Ownership and Retention Guidelines” on page 56.

and PSUs granted to our NEOs prior to the adoption of the 2020 Plan, including, among other things, the vesting and forfeiture provisions. The 2020 Plan and applicable equity award agreement govern the terms of the options, RSUs and PSUs granted to our NEOs since 2021.

(2)

The options granted under the 2016 Plan and 2020 Plan vest in four equal installments on each of the first through fourth anniversaries of the date of grant.

(3)

Prior to our IPO and the adoption of the 2020 Plan and our 2016 2016 Plan, certain of our NEOs received stock options pursuant to our Amended and Restated SiteOne Landscape Supply, Inc. Stock Incentive Plan (f/k/a CD&R Landscapes Parent, Inc. Stock Incentive Plan) (the “Stock Incentive Plan”). The options granted under the Stock Incentive Plan vested in five equal installments on each of the first through fifth anniversaries of the date of grant.

(4)

(5)

The RSUs will vest and settle into shares of common stock in four equal annual installments on each of the first through fourth anniversaries of the date of grant, subject to the NEO’s continued employment (except for the 2/9/2023 grants to Mr. Black and Mr. Guthrie who satisfied the conditions for retirement under the 2020 Plan or the applicable award agreements).

(6)

Based on the closing price of the Company’s stock on December 29, 2023 ($162.50), the final trading day of the 2023 Fiscal Year.

(1)

The value realized on option exercises is the difference between the market price of the underlying securities at exercise and the exercise or base price of the options.

(2)

A participant is vested in the right to receive PSUs granted in 2021 under the applicable PSU award agreement as of December 31, 2023 (the end of the performance cycle). However, pursuant to the terms of the award, the actual number of shares to be awarded to the participant is not known until the Human Resources and Compensation Committee determines the applicable performance levels of the underlying (i) relative EBTA growth and (ii) absolute ROIC after the end of the performance cycle. Accordingly, the values in the table above reflect the target number of PSUs awarded in 2021 multiplied by the closing price of the Company’s stock on December 29, 2023 ($162.50), the final trading day of the 2023 Fiscal Year. The final value realized will not be known until after the Human Resources and Compensation Committee completes its determination in verifying the financial information used to calculate the applicable performance level achievements, which may result in a greater or lesser value than shown above. After completion of this process, the actual transfer of common stock is made to participants. As a result, the following amounts have been added to the “Stock Awards” column above to reflect the PSUs that have vested but not settled and, therefore, no value has been received by our NEOs as of March 26, 2024:

	Estimated PSU Stock Awards
	Number of shares vested (#)		Value realized on vesting ($)
Doug Black		6,018		977,925
John Guthrie		1,153		187,363
Briley Brisendine		1,253		203,613
Scott Salmon		1,103		179,238
Joseph Ketter		952		154,700

(3)

The value realized on vesting is determined by multiplying the number of units vested by our closing stock price on the date the units vested. For 2023, units granted on February 6, 2019 vested on February 6, 2023, units granted on March 11, 2019 vested on March 11, 2023, units granted on February 5, 2020 vested on February 5, 2023, units granted on February 11, 2021 vested on February 11, 2023 and units granted on February 10, 2022 vested on February 10, 2023, and the closing stock price on those dates was $155.52, $135.60, $159.86, $146.87 and $146.87, respectively.

Potential Payments Upon Termination or Change-in-Control

Separation Benefit Agreements with Messrs. Black, Guthrie, Brisendine, Salmon and Ketter

Severance protections, particularly in the context of a change-in-control transaction, can play a valuable role in attracting and retaining key executive officers. The potential occurrence of a change-in-control transaction would create uncertainty regarding the continued employment of our NEOs. This uncertainty results from the fact that many change-in-control transactions result in significant organizational changes, particularly at the NEO-level. In order to encourage our NEOs to remain employed with the Company during an important time when their prospects for continued employment are often uncertain, we provide our NEOs and other senior executives with severance benefits if the executive’s employment is terminated by the Company “without cause” or by the executive for “good reason” (each as defined below) in connection with a change-in-control and outside of a change-in-control. Because a termination by the executive for good reason may be conceptually the same as a termination by the Company without cause, and because in the context of a change-in-control, potential acquirers would otherwise have an incentive to constructively terminate the executive’s employment to avoid paying severance, it is appropriate to provide severance benefits in these circumstances.

The Board evaluates the level of severance benefits to each NEO on a case-by-case basis, and in general, considers these severance protections to be an important part of the compensation provided to our NEOs and consistent with competitive practices.

Accordingly, in November 2023, the Company entered into separation benefit agreements (collectively, the “Separation Agreements”) with each of the Company’s NEOs, as well as other senior executives of the Company. The Separation Agreements replace, on the one hand, the employment agreement previously entered into by the Company with Mr. Black and, on the other hand, the separation benefit agreements previously entered into by the Company with the other NEOs.

The Separation Agreements provide that, if the NEO’s employment is terminated “without cause” or if the NEO terminates his employment for “good reason” outside of the 12-month period following a change-in-control, the NEO is entitled to receive the following:

•

all salary, prior year bonus, expense reimbursements and benefits earned or incurred but unpaid as of the date of termination (the “Base Termination Compensation”);

•

severance pay consisting of an amount equal to (a) 18 months of the NEO’s base salary, at the greater of the rate in effect (1) at the effective time of termination and (2) prior to the event giving rise to good reason, paid in monthly installments beginning on the 60th day following the termination date, and (b) the NEO’s annual bonus for the year in which his employment terminates based on actual results, prorated for the portion of the year that the NEO had remained employed and paid at the time executive annual bonuses are paid for the fiscal year of termination (but no later than 2.5 months after the end of such year); and

•

continued medical, dental and vision insurance coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) for 18 months at active employee rates, with the COBRA premium amount reimbursed to the NEO on a monthly basis (the “Benefit Continuation”).

With respect to the description of severance pay described above, Mr. Black’s Separation Agreement provides that, in addition to the benefits described above, Mr. Black is also entitled to an annual bonus for the year in which his employment terminates, determined based on target results.

If the NEO’s employment is terminated “without cause” or if the NEO terminates his employment for “good reason” within the 12-month period following a change-in-control, the NEO is entitled to receive the following:

•

the Base Termination Compensation;

•

severance pay consisting of an amount equal to two times the sum of (a) the NEO’s base salary, at the greater of the rate in effect (1) at the time of termination and (2) prior to the event giving rise to good reason and (b) the NEO’s annual bonus for the year in which his employment terminates determined based on target results, paid in a lump sum on the 40th day following the termination date;

•

an amount equal to the NEO’s annual bonus for the year in which his employment terminates determined based on actual results, prorated for the portion of the year that the NEO had remained

TABLE OF CONTENTS

employed and paid at the time executive annual bonuses are paid for the fiscal year of termination (but no later than 2.5 months after the end of such year); and

•

the Benefit Continuation.

If the NEO’s employment is terminated for “cause” or the NEO voluntarily terminates his employment without “good reason” or if the NEO’s employment is terminated due to death, he is only entitled to receive the Base Termination Compensation. If the NEO’s employment is terminated due to disability, he is entitled to receive (a) the Base Termination Compensation and (b) continued medical, dental and vision insurance coverage for 18 months at active employee rates.

Payment of the above termination compensation and/or benefits under the Separation Agreements (other than the Base Termination Compensation) is conditioned on each NEO signing and not revoking a general release of claims in favor of the Company and complying with the restrictive covenants set forth in any written agreement between the NEO and the Company.

“Cause” is defined in the Separation Agreements as (a) conviction of, or plea of nolo contendere to, a crime constituting a felony in the U.S. or a specified type of misdemeanor, (b) willful or grossly negligent failure to perform material duties, (c) willful material violation of Company policy, (d) material breach of a binding agreement to which he is a party and (e) willful conduct that materially and demonstrably harms the Company or any of its subsidiaries. Notice and cure provisions apply.

“Good Reason” is defined in the Separation Agreements as (a) a material reduction in base salary, (b) a material reduction in annual incentive compensation opportunity, (c) a material diminution in his authority, duties or responsibilities without consent (d) a relocation of the NEO’s principal place of employment by more than 50 miles, or (e) material breach by the Company or any of its subsidiaries of an agreement to which the NEO is the counterparty. Mr. Black’s Separation Agreement further provides that a failure to nominate Mr. Black to the Board also constitutes “Good Reason.” Notice and cure provisions apply.

Accelerated Vesting of Options, RSUs and PSUs on Certain Terminations of Employment or a Change-In-Control

2020 Plan and 2016 Plan

For awards granted under the 2020 Plan or 2016 Plan, if a NEO’s employment is terminated as a result of the NEO’s death or disability, then all unvested options and RSUs held by the NEO at the time of his or her death or disability will accelerate and become vested. For PSUs granted under the 2020 Plan, if a NEO’s employment is terminated as a result of the NEO’s death or disability, then a pro rata portion of the PSUs will vest (based on target level performance), determined by multiplying the target award by (x) the number of completed months that the NEO was employed with the Company during the performance period and (y) 36 months.

If a NEO resigns or retires at or after the age of 60, and has been an employee of the Company for at least 10 years, subject to certain non-competition requirements, then unvested options and RSUs will continue to vest on the prescheduled vesting dates in the two-year period following the effective date of such resignation or retirement (in the case of options granted since 2018, and in the case of RSUs granted in since 2020). PSUs will vest in a pro-rated number at the end of the performance cycle (based on actual performance) as follows: (x) if retirement occurs in year one of the performance period, then 33% of the PSUs will vest; (y) if retirement occurs in year two of the performance period, then 66% of the PSUs will vest; and (z) if retirement occurs in year three of the performance period, then 100% of the PSUs will vest.

In February 2023, our Human Resources and Compensation Committee approved amendments to the applicable equity award agreements governing the terms of the options, RSUs and PSUs granted under the 2020 Plan. Pursuant to such amendments, all unvested options and RSUs granted to a NEO after the effective date of the amendments under an applicable award agreement, as amended, will fully vest following the end of their employment, generally in four equal annual installments and expire in 10 years for options, if such NEO’s combined age (minimum of 55 years of age) and completed years of employment with the Company (minimum of 5 years of service) equals 65 or more (i.e., the “Rule of 65”). The amendments did not alter (i) any equity award agreements outstanding on or prior to February 8, 2023, or (ii) the pro-rated vesting schedule with respect to PSUs, as described above, other than to change the definition of retirement to reflect the Rule of 65.

Upon a termination without cause, unvested options and RSUs will vest in an amount equal to the number of options and RSUs, as applicable, that would have vested on the next scheduled vesting date, had the NEO remained

TABLE OF CONTENTS

employed through such vesting date, multiplied by a fraction, (x) the numerator of which is the number of days from the immediately preceding vesting date (or the grant date, if the termination of employment occurs prior to the first vesting date) and (y) the denominator is the number of days from the immediately preceding vesting date (or the grant date, if the termination of employment occurs prior to the first vesting date) through such next vesting date. PSUs will vest (based on actual performance) at the end of the performance period, determined by multiplying the target award by a fraction (x) the numerator of which equals the number of completed months that the NEO was employed with the Company during the performance period and (y) the denominator of which equals 36 months.

If the Company experiences a “change-in-control,” as defined below, no vesting or cancellation of awards granted under the 2020 Plan or 2016 Plan will occur if awards are assumed and/or replaced in the change-in-control with substitute awards having the same or better terms and conditions, provided that any substitute awards must fully vest on a participant’s involuntary termination of employment “without cause” or voluntary termination with “good reason,” in each case occurring within one year following the date of the change-in-control. If the Human Resources and Compensation Committee determines that substitute awards will not be provided in the change-in-control, all outstanding awards would fully vest and be cancelled for the same per share payment made to the stockholders in the change-in-control (less, in the case of options and SARs, the applicable exercise or base price). The Human Resources and Compensation Committee has the ability to prescribe different treatment of awards in the award agreements.

Notwithstanding the foregoing, in the event of a change-in-control, PSUs will automatically convert into RSUs (based on target level, in the event the change-in-control occurs prior to the completion of year two of the performance period, or based on performance to date, in the event the change-in-control occurs in year three of the performance period). The RSUs will vest at the end of the performance period unless the RSUs are not assumed and/or replaced or the participant’s employment is terminated without cause or voluntarily with good reason as described above, in which case the RSUs will vest immediately.

Under the 2016 Plan, a “change-in-control” is generally defined as the first to occur of the following events:

•

any transaction that results in the acquisition by any person, entity or “group” (as defined in Section 13(d) of the Exchange Act) of more than 50% of the combined voting power of the Company’s then outstanding voting securities, other than any such acquisition by the Company, any of the Company’s subsidiaries, any employee benefit plan of the Company or any of the Company’s subsidiaries, or any affiliates of any of the foregoing;

•

within any 12-month period, the persons who were the Company’s directors at the beginning of such period (called “incumbent directors”) cease to constitute at least a majority of the Board, except that any director elected or nominated for election to the Board by a majority of the incumbent directors then still in office is deemed to be an incumbent director for these purposes; or

•

the sale, transfer or other disposition of all or substantially all of the Company’s assets to one or more persons or entities that are not, immediately prior to such sale, transfer or other disposition, affiliates of the Company.

Under the 2020 Plan, a “change-in-control” is generally defined as the first to occur of the following events:

•

the consummation of any transaction that results in the acquisition by any person, entity or “group” (as defined in Section 13(d) of the Exchange Act) of more than 50% of the combined voting power of the Company’s then outstanding voting securities, other than any such acquisition by the Company, any of the Company’s subsidiaries, any employee benefit plan of the Company or any of the Company’s subsidiaries, or any affiliates of any of the foregoing;

•

within any consecutive 24-month period, incumbent directors cease to constitute at least a majority of the Board, except that any director elected or nominated for election to the Board by a majority of the incumbent directors then still in office is deemed to be an incumbent director for these purposes (provided, that that any member of the Board whose initial assumption of office occurs as a result of (including by reason of the settlement of) an actual or threatened proxy contest, election contest or other contested election of directors will not be considered an Incumbent Director for the purposes of the 2020 Plan);

Summary of Potential Payments Upon Termination of Employment or Upon the Occurrence of a Change-In-Control

The following table shows the estimated value of benefits to Messrs. Black, Guthrie, Brisendine, Salmon and Ketter if their employment had been terminated under the various circumstances described below as of December 31, 2023, the last day of the 2023 Fiscal Year, or upon the occurrence of a change-in-control (“CIC”). The amounts shown in the table exclude accrued but unpaid base salary, unreimbursed employment-related expenses, accrued but unpaid vacation pay (which payments and reimbursements would be made to all salaried associates), distributions under our 401(k) retirement plan (which plan is generally available to all of our salaried associates) and the value of equity awards that were vested by their terms as of December 31, 2023 (other than vested but unsettled PSUs awarded in February 2021). For a description of the definition of “cause” and the timing of the payments see “Potential Payments Upon Termination or Change-In-Control — Separation Benefits Agreements with Messrs.

Director Compensation

The Board has adopted a non-employee director compensation policy. The Human Resources and Compensation Committee has engaged FW Cook as an outside compensation consultant to ensure the compensation paid to our directors remains competitive, specifically as a result of a market benchmarking survey, using the same peer companies that are used to benchmark executive compensation. Under current policy, all non-employee directors are entitled to cash compensation as set forth below, payable in arrears on a quarterly basis:

	Annual Retainer
Board:
All non-employee members		$	80,000
Lead Director		$	35,000
Audit Committee:
Chair		$	32,500
Non-Chair members		$	12,500
Human Resources and Compensation Committee:
Chair		$	27,500
Non-Chair members		$	10,000
Nominating and Corporate Governance Committee:
Chair		$	22,500
Non-Chair members		$	7,500

Each non-employee director has the right to elect to receive all or a portion of his or her annual cash retainer in the form of, as applicable based on whether such non-employee director has met the stock ownership and retention requirements set forth in the Company’s Non-Employee Director Equity Ownership Policy, deferred share units (“DSUs”) or fully vested RSUs, in each case, using the fair market value of a share of the Company’s common stock on the applicable grant date. The DSUs are subject to the deferral requirements of Section 409A of the Internal Revenue Code of 1986, as amended. Non-employee directors may also elect to defer RSUs until the termination of their Board service (or a specified date).

Under the policy, on the date of each annual meeting of our stockholders, each continuing non-employee director is eligible to receive a prospective equity award for the coming year of service with a grant date fair value of $130,000 in the form of DSUs. The DSUs granted to our non-employee directors under the 2020 Plan vest upon the earlier of (i) the first anniversary of the grant date and (ii) the next annual meeting of stockholders, in each case, subject to such non-employee director’s continued service as a director or other service provider.

In the event of a non-employee director’s termination of service prior to the end of the vesting period due to a voluntary resignation from the board or involuntary removal without cause, a prorated portion of the DSUs will become vested.

In the event of a director’s termination due to death or disability or change-in-control prior to the non-employee director’s termination of service, the vesting period will lapse and the DSUs will become fully vested.

We have also agreed to reimburse all reasonable out-of-pocket expenses incurred by non-employee directors in attending in-person Board and committee meetings.

In August 2022, the Board approved certain amendments to the non-employee director compensation policy. Pursuant to the amended non-employee director policy, our non-employee directors will receive either DSUs or RSUs depending on whether such director has met the stock ownership and retention requirements set forth in the Company’s Non-Employee Director Equity Ownership Policy on the applicable grant date. Those non-employee directors that have met the applicable stock ownership and retention requirements are entitled to receive RSUs and may elect to defer settlement of their RSUs until the termination of their Board service (or a specified date). Vested RSUs granted to non-employee directors settle into the Company’s common stock at the earlier to occur of the vesting date, termination of the director’s service on the Board, or until a change of control of the Company. Settlement may also be deferred at the director’s election until a specified date after the vesting date.

Director Compensation for 2023 Fiscal Year

The following table summarizes the compensation paid to our non-employee directors for the 2023 Fiscal Year.

(1)

Reflects the grant date fair value of 878 DSUs granted to Messrs. Douglas, Dunbar and Wyszomierski and of 878 RSUs granted to Mr. Diaz and Mses. Drake and Isbell, each of which have met the stock ownership and retention requirements set forth in the Company’s Non-Employee Director Equity Ownership Policy as further described above, on May 11, 2023. The grant date fair values of the DSUs and RSUs are computed in accordance with FASB ASC Topic 718, modified to exclude any forfeiture assumptions related to service-based vesting conditions, determined by dividing the grant value by the closing price of our common stock on the grant date.

Non-Employee Director Stock Ownership and Retention Guidelines

Our Non-Employee Director Equity Ownership Policy requires each non-employee director to own shares of the Company’s common stock having an aggregate value equal to a multiple of the annual cash retainer as followers:

Position			Multiple
Non-Employee Director			5x Annual Cash Retainer

All shares of the Company’s common stock owned directly or indirectly, and DSUs held by the non-employee director, count for purposes of the ownership policy. Non-employee directors are required to maintain 100% of after-tax shares earned from the non-employee director compensation program until the ownership threshold has been achieved but are not required to purchase equity in the open market in order to comply with the ownership policy.

Also, DSUs granted to our non-employee directors under the 2020 Plan and grants under the 2016 Plan pursuant to our non-employee director compensation policy will not settle into the Company’s common stock until after the director receiving the grant has ceased to serve as a non-employee director on the Board or a change-in-control. Currently, each non-employee director is in compliance with the Non-Employee Director Stock Ownership and Retention Guidelines.

Human Resources and Compensation Committee Interlocks and Insider Participation

Messrs. Dunbar and Diaz and Ms. Isbell all served as members of the Human Resources and Compensation Committee during the 2023 Fiscal Year. No member of the Human Resources and Compensation Committee during the 2023 Fiscal Year is or at any time has been an officer or employee of the Company or any of its subsidiaries. None of our executive officers serves or has served on the compensation committee or the board of directors of another entity which had an executive officer serving on the Human Resources and Compensation Committee during the 2023 Fiscal Year.

Includes 555,736 stock options, 36,563 RSUs, 38,870 PSUs, and 54,669 DSUs granted to officers and directors pursuant to the 2020 Plan, 2016 Plan, and the Stock Incentive Plan.

CEO Pay Ratio

For the 2023 Fiscal Year: (i) the total compensation of our median employee (excluding Mr. Black, our CEO) was $59,013; and (ii) the annual total compensation of Mr. Black, our CEO, was $5,430,348. Based on this information, the ratio of the annual total compensation of our CEO to our median employee was 92 to 1.

Methodology

To identify our median employee, as well as to determine the annual total compensation of such median employee, we used our total employee population located in the United States as of December 31, 2023, which consisted of approximately 7,500 individuals. Employees located in Canada were excluded, as permitted under applicable SEC rules. We used the annualized pay rate for both our hourly and salaried associates active as of December 31, 2023. We included all permanent associates, including new associates who were hired during the 2023 Fiscal Year but did not work for the Company for the entire fiscal year. We did not make any cost-of-living adjustments in identifying the median employee.

With respect to the annual total compensation of our CEO, we used the amount shown in the 2023 “Total” column of the “Summary Compensation Table” on page 47.

Median Employee

Using the methodology described above we determined our median employee was a full-time associate located in South Carolina. Our median employee’s total annual compensation, calculated using the same methodology used in calculating Mr. Black’s annual total compensation for the 2023 Fiscal Year, was $59,013.

Pay Versus Performance

As required by Section 953(a) of the Dodd-Frank Act and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid (“CAP”) and certain financial performance of the Company. The Human Resources & Compensation Committee does not utilize CAP as the basis for making compensation decisions.For further information concerning the Company’s variable pay-for-performance philosophy and how the Company aligns executive compensation with the Company’s performance, refer to “Compensation Discussion and Analysis” beginning on page 34. Because CAP includes multiple years of grants, the calculation of CAP each year is heavily impacted by the change in Company stock price and, therefore, may be higher or lower than the values shown in the “Summary Compensation Table” on page 47.

GENERAL INFORMATION

~~Stock Ownership~~Stock Ownership

The following table sets forth information as of March ~~18, 2019~~8, 2024 with respect to the ownership of our common stock by:

•

each person known to own beneficially more than five percent of our common stock;

•

each of our directors;

•

each of our NEOs; and

•

all of our current executive officers and directors as a group.

The amounts and percentages of shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Percentage computations are based on ~~40,978,541~~45,186,208 shares of our common stock outstanding as of March ~~18, 2019.~~8, 2024.

Except as otherwise indicated in these footnotes, each of the beneficial owners listed has, to our knowledge, sole voting and investment power with respect to the indicated shares of common stock. Unless otherwise set forth in the footnotes to the table, the address for each listed stockholder is c/o SiteOne Landscape Supply, Inc., 300 Colonial Center Parkway, Suite 600, Roswell, Georgia 30076.

QUESTIONS AND ANSWERS ABOUT
THE PROXY MATERIALS AND ANNUAL MEETING

What are the proxy materials and why am i receiving them?

The accompanying proxy is delivered and solicited on behalf of the Board, in connection with our Annual Meeting to be held at the Atlanta Airport Marriott Gateway Hotel, located at 2020 Convention Center Concourse, Atlanta, Georgia 30337, on Tuesday, May 7, 2024, at 9:00 a.m., Eastern Time. As a stockholder, you are invited to attend the Annual Meeting and are requested to vote on the items of business described in this Proxy Statement. This Proxy Statement includes information that we are required to provide to you under SEC rules and is designed to provide you with information relevant to the voting of your shares at the Annual Meeting. The proxy materials include this Proxy Statement and our Annual Report for the 2023 Fiscal Year and have been made available to you by either mail or Notice.

All stockholders and beneficial owners may access the proxy materials at www.proxyvote.com. In addition, this Proxy Statement and our Annual Report are available on our investor relations website located at investors.siteone.com/sec-filings. If you would like to receive a paper copy of our proxy materials at no charge, please write to SiteOne Landscape Supply, Inc., 300 Colonial Center Parkway, Suite 600, Roswell, Georgia 30076, Attention: Briley Brisendine, Secretary.

What is notice and access and why do we elect to use it?

As permitted by the SEC, Notice and Access provides companies with the ability to make proxy materials available to stockholders electronically via the Internet. We have elected to provide our stockholders with the Notice instead of mailing a full set of printed proxy materials in the mail. The Notice is a document that provides instructions regarding how to:

	①			View our proxy materials on the Internet
	②			View your shares
	③			Request printed copies of these materials, including the proxy card or voting instruction card

On or about March [•], 2024, we began mailing the Notice to beneficial owners and posted our proxy materials on the website referenced in the Notice. As more fully described in the Notice, stockholders who received the Notice may choose to access our proxy materials on the website referenced in the Notice or may request a printed set of our proxy materials. You may also choose to receive future proxy materials by email. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you revoke it.

We have chosen to provide electronic access to our proxy materials because utilizing Notice and Access will save us the cost of printing and mailing documents to you and will reduce the environmental impact of our Annual Meeting.

Who is entitled to vote at the annual meeting?

The record date for stockholders entitled to notice of, and to vote at, the Annual Meeting is March 8, 2024. At the close of business on that date, we had 45,186,208 shares of common stock outstanding and entitled to be voted at the Annual Meeting. We have one stockholder of record, with many more beneficial stockholders who hold shares through a broker, bank or other nominee. Each outstanding share of common stock is entitled to one vote.

Registered Stockholders. If your shares are registered directly in your name with our transfer agent, Equiniti (“EQ”), you are considered the stockholder of record with respect to those shares and the proxy materials were

TABLE OF CONTENTS

provided to you directly by us. As a stockholder of record, you have the right to grant your voting proxy directly to the individuals named as proxies on the proxy card in one of the manners listed on the proxy card or to vote at the Annual Meeting.

Beneficial Stockholders. If your shares are held in a stock brokerage account or by a broker, bank or other nominee, you are considered the beneficial owner of shares held in “street name” and the proxy materials were forwarded to you by your broker, bank or other nominee, who is considered, with respect to those shares, to be the stockholder of record. As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares using the methods prescribed by your broker, bank or other nominee on the voting instruction card you received with the proxy materials. Like stockholders of record, beneficial owners are invited to attend the Annual Meeting. However, because you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you follow your broker’s, bank’s or other nominee’s procedures for obtaining a legal proxy from it, as the stockholder of record.

What items of business will be voted on at the annual meeting?

The items of business scheduled to be voted on at the Annual Meeting are:

	Proposal 1:			Elect the three Class II nominees named in the accompanying Proxy Statement as Class II directors for a term expiring at the 2027 Annual Meeting of Stockholders.
	Proposal 2:			Approve an amendment to our Charter to limit the liability of certain officers of the Company as permitted pursuant the Delaware General Corporation Law.
	Proposal 3:			Ratify the selection of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 29, 2024.
	Proposal 4:			Hold a non-binding advisory vote to approve executive compensation.
	Other Proposals:			Transact such other business as may properly come before the Annual Meeting or any reconvened meeting following any adjournment or postponement thereof.

How does the board recommend i vote on these proposals?

	Proposal 1:			“FOR” each of the Class II nominees named in this Proxy Statement as Class II directors for a term expiring at the 2027 Annual Meeting of Stockholders.
	Proposal 2:			“FOR” the proposal to amend our Charter to limit the liability of certain officers of the Company as permitted pursuant to the Delaware General Corporation Law.

	Other Proposals:			At the discretion of Doug Black and Briley Brisendine, the persons designated as proxies for the Annual Meeting, either “FOR”, “AGAINST” or “ABSTAIN” with regard to any other business that may properly come before the Annual Meeting.

How many shares are needed to hold the annual meeting?

A quorum is required for our stockholders to conduct business at the Annual Meeting. The presence in person or by proxy of the holders of record of a majority of the shares of common stock entitled to vote at the Annual Meeting is necessary to constitute a quorum at the Annual Meeting. Virtual attendance at the Annual Meeting

With regard to Proposals 2, 3 and 4, stockholders may vote “FOR” or “AGAINST” each proposal or may “ABSTAIN” from voting with regard to each proposal. A plurality vote is required for the election of directors, which means that the nominees receiving the highest number of “FOR” votes will be elected. “WITHHOLD” votes will have no effect on the election of the nominees in Proposal 1 because they are not considered votes cast for the foregoing purpose.

A “broker non-vote” occurs when a broker holding shares for a street name holder submits a valid proxy but does not vote on a particular proposal because the broker has not received voting instructions from the stockholder for whom it is holding shares and does not have discretionary authority to vote on the matter. Broker non-votes will have no effect on Proposal 1 because broker non-votes are not considered a vote cast for purposes of determining a plurality. Broker non-votes will have the same effect as a vote “AGAINST” on Proposal 2. Brokers will only have discretionary authority to vote on Proposal 3, the ratification of the appointment of the independent registered public accounting firm. Broker non-votes will have no effect on Proposal 4 because broker non-votes will not be counted as shares entitled to vote on this matter.

(3)

As an advisory vote, this proposal is not binding. However, the Board and its Human Resources and Compensation Committee will consider the outcome of this vote when making future compensation decisions with respect to our executive officers.

How do i vote?

To be valid, your vote by Internet, telephone or mail must be received by the deadline specified on the proxy card or voting information form, as applicable. Whether or not you plan to attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the meeting.

Stockholders voting by Internet or telephone should understand that, while we and Broadridge Financial Solutions, Inc. (“Broadridge”) do not charge

any fees for voting by Internet or telephone, there may still be costs, such as usage charges from Internet access providers and telephone companies, for which you are responsible.

The deadline for telephone and Internet voting is 11:59 p.m., Eastern Time, on May 6, 2024. The giving of a proxy will not affect your right to vote at the Annual Meeting should you decide to attend.

How can i attend the annual meeting?

Attendance at the Annual Meeting will be limited to stockholders of the Company as of the record date (or their authorized representatives). All stockholders should be prepared to present a valid government-issued photo identification, such as a driver’s license or passport. Beneficial stockholders holding their shares through a broker, bank or other nominee will need to bring proof of beneficial ownership as of March 8, 2024, the record date, such as a recent brokerage account statement, the voting instruction card provided by their broker, bank or other nominee or similar evidence of ownership. Stockholders of record will be verified against an official list available at the registration area. We reserve the right to deny admission to anyone who cannot show sufficient proof of stock ownership as of the record date.

Can i vote in person at the annual meeting?

For stockholders with shares registered directly in their names with our transfer agent (EQ) on the record date (March 8, 2024), you may vote your shares in person at the Annual Meeting. For stockholders with shares registered in the name of a broker, bank or other nominee, you will need to obtain a legal proxy from the broker, bank or other nominee that holds your shares before you can vote your shares in person at the Annual Meeting. Written ballots will be passed out to anyone who wants to vote at the Annual Meeting. Even if you plan to attend the Annual Meeting, we encourage you to vote by proxy in advance. If you vote by Internet or by telephone, you do not need to return your proxy card. Voting in advance will not limit your right to vote at the Annual Meeting if you decide to attend in person.

What happens if the annual meeting is postponed or adjourned?

Unless a new record date is fixed, your proxy will still be valid and may be voted at the postponed or adjourned Annual Meeting. You will still be able to change or revoke your proxy at any time until it is voted.

How will my proxy be voted?

Proxies are being solicited on behalf of the Board for use at the Annual Meeting. All valid proxies that are not revoked will be voted as specified by the stockholder authorizing the proxy. In the absence of instructions, the shares of the common stock represented by valid proxies will be voted “FOR” the election of the persons named in this Proxy Statement as nominees for director of the Company, “FOR” on the proposal to amend the Company’s Charter, “FOR” the ratification of Deloitte as the Company’s independent registered public accounting firm for the 2023 Fiscal Year and “FOR” the proposal regarding the advisory vote approving executive compensation.

How do i change or revoke my proxy?

Who will count and certify the votes?

Representatives of Broadridge and our corporate secretary will count the votes and certify the election results.

TABLE OF CONTENTS

When and where will i be able to find the voting results?

You can find the official results of voting at the Annual Meeting in our Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If the official results are not available at that time, we will provide preliminary voting results in the Form 8-K and will provide the final results in an amendment as soon as they become available.

Who pays for the cost of proxy preparation and solicitation?

The accompanying proxy is solicited by the Board. We have engaged Broadridge to assist us in the distribution of proxy materials and to provide voting and tabulation services for the Annual Meeting for an estimated cost of $165,000. All costs of the solicitation of proxies will be borne by us. We pay for the cost of proxy preparation and solicitation, including the reasonable charges and expenses of brokerage firms, banks, trusts or nominees for forwarding proxy materials to street name holders. To reduce costs, we primarily solicit proxies via Notice and Access. We are also soliciting proxies by mail. In addition, our directors, officers and associates may solicit proxies by telephone or other means of communication personally. Our directors, officers and associates will receive no additional compensation for these services other than their regular compensation.
