Dear Fellow Stockholders:

On behalf of the Board of Directors of SiteOne Landscape Supply, Inc., I would like to express our appreciation for your continued interest in our company.

It is my pleasure to invite you to SiteOne’s Annual Meeting of Stockholders, to be held on Wednesday, May 12, 2021, at 9:00 a.m., Eastern Time.

2020 was a year unlike any other. Faced with many challenges associated with COVID-19, we established four key objectives to ensure we were focused on what was important:

•

Keep everyone safe, including associates, customers, suppliers and communities;

•

Serve and support our customers as the leader in the Green Industry;

•

Manage our business to meet demand; and

•

Take care of each other during every step.

I am very pleased with our accomplishment of these objectives during the year.

In light of the ongoing public health impacts of COVID-19, we have determined that the Annual Meeting will be a virtual meeting, conducted solely via the Internet, with no physical in-person meeting. Stockholders will be able to attend, vote and submit questions (both before and during a portion of the meeting) from any location via the Internet at www.virtualshareholdermeeting.com/SITE2021. If you plan to participate in the virtual meeting, please see “Proxy Statement Q&A.”

The formal Notice of Annual Meeting and Proxy Statement are enclosed with this letter. The Proxy Statement describes the matters to be acted upon at the Annual Meeting. It also describes how the Board operates and provides compensation and other information about the management team and Board.

Your vote is important. Whether or not you plan to attend the Annual Meeting, I strongly encourage you to vote as soon as possible. You may vote over the Internet, by telephone or by mailing a proxy or voting instruction card. For instructions on voting, please refer to the Notice of Internet Availability of Proxy Materials you received in the mail or the section entitled “How do I vote” beginning on page 12 of the Proxy Statement. If you received a paper copy of the Proxy Statement, please use your enclosed proxy card to vote.

As part of our commitment to transparency, this past year we developed and published our inaugural Responsibility Report which includes our reporting under the Sustainability Accounting Standards Board (“SASB”) framework and details our programs and progress across a number of important human capital and sustainability topics. We invite you to review this report and learn more about our efforts by visiting the “Responsibility” tab of our website at https://www.siteone.com/responsibility.

Finally, I would like to once again emphasize that the Board places a very high value on feedback from our stockholders. In 2020, we continued our robust stockholder outreach program, now in its third year, by meeting with investors who collectively held nearly 70% of our outstanding shares. Please review the

Vision and Values

At SiteOne, we are committed to becoming a company of excellence. While this can have many interpretations, we define this vision using five objectives:

Be a great place to work for our associates;

Deliver superior quality, service and value to our customers;

Be the distributor of choice for our suppliers;

Achieve industry-leading financial performance and growth for our shareholders; and

Be a good neighbor in our communities.

These five objectives provide our “True North” and guide us in the people that we hire, the decisions that we make and the capabilities that we build. As the largest wholesale distributor in the Green Industry, we feel a sense of responsibility to set a high bar across all five objectives in creating excellence for all of our stakeholders. To accomplish our vision, we strive to consistently practice the following seven values across all aspects of our Company:

Always Safe — We take personal responsibility for our safety and for the safety of others.

Customer Obsessed — We are passionate about making our customers successful.

Continuously Improving — We quickly adopt best practices to drive growth and deliver world-class results.

Team Players — We respect and support each other and put the team first.

Professional — We do everything with quality and integrity and never cut corners.

Talent Focused — We recruit, develop, mentor and retain the best people.

Accountable — We think and act like owners and leverage our resources to succeed.

In addition, we are committed to operating our business in a way that reflects thoughtful environmental management, including decreasing any negative environmental impacts of our business operations and offering eco-friendly products which are beneficial for the environment and more efficient for our customers. Additional details about the processes and programs we have implemented to achieve our vision may be found in our Responsibility Report, which is available on our website, at https://www.siteone.com/responsibility.

Governance Evolution Through Stockholder Engagement & Responsive Actions

The Board is committed to strong corporate governance. As we continue our transition from a “controlled company” to a widely-held company following the completion of our former sponsors’ sell-down of their equity ownership positions in 2017, we are committed to evolving our Board and our corporate governance processes to reflect the changes in our Company’s business and stockholder base. We are committed to establishing and maintaining strong corporate governance practices that reflect high standards of ethics and integrity and promote long-term stockholder value.

TABLE OF CONTENTS

[MISSING IMAGE: tm219017d2-pc_stockhold4c.jpg]

Stockholder feedback received through engagement is an integral part of the Board’s corporate governance review process. The Board and management team are committed to building and maintaining open communication whereby stockholders can express their views, as well as gain insight into our perspectives on long-term stockholder value.

We continue to engage with our stockholders to deepen the Board’s understanding of our stockholders’ interests and priorities. In addition to ordinary course investor conferences, earnings calls and one-on-one investor conference calls and meetings, in which we have been actively involved since our IPO, we conducted targeted outreach with stockholders representing a substantial portion of our stockholder base to discuss our corporate governance practices in each of the past three years. For our stockholder outreach program in 2020, we invited our top 20 stockholders to provide feedback on our governance practices. Of these top 20 stockholders, 17 (85%) engaged with us and provided feedback, representing nearly 70% of our shares outstanding. Our Board of Directors, including the Nominating and Corporate Governance Committee of the Board (the “Nominating and Corporate Governance Committee”) and the Human Resources and Compensation Committee (the “Human Resources and Compensation Committee”), reviewed feedback from our stockholders.

As a result of our discussions with stockholders since 2018, we have made a number of enhancements to our governance practices, including:

✔

Eliminating supermajority voting requirements;

✔

Appointing an additional female director;

✔

Adding performance shares to executive officer compensation;

✔

Amending our Executive Officer Ownership Policy to increase the CEO holding requirement and exclude the value of in-the-money options from ownership calculation;

✔

Issuing our inaugural Responsibility Report aligned with the SASB framework; Enhancing disclosure in our proxy statement regarding director skills, background and qualifications;

✔

Amending our anti-hedging policy to prohibit pledging of Company stock by directors and executive officers;

✔

Adopting a new Non-Employee Director Equity Ownership Policy; and

✔

Significantly improving our social and environmental policies, including adopting a Human Rights Policy, Supplier Code of Conduct and Environmental Policy.

During this year’s stockholder outreach program, stockholders shared perspectives on a number of important governance issues, including:

•

Our proactive engagement and attention to environmental, social, and governance (“ESG”) issues, which several investors noted was atypical for companies of our size;

•

Our classified board structure, which generally garners a positive or constructive view at this time; and

•

Perspectives (sometimes differing) on executive compensation design, particularly on preferred performance metrics and equity vehicles.

TABLE OF CONTENTS

Regarding our classified board structure, our stockholders acknowledged our Company’s specific circumstances including a relatively small market capitalization, cyclical industry and track record of stockholder returns since our IPO. Through our discussions, we learned that our investors generally have a positive or constructive view of our classified board structure at this point in time as a result of these company specific circumstances. Only one stockholder we engaged with this year (representing approximately 1.7% of our outstanding shares) expressed an unfavorable view of our classified board structure.

We intend to continue a cycle of year-round stockholder engagement in 2021, including our regular participation at analyst meetings and conferences and periodic engagement on corporate governance and compensation topics. 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 considers feedback from these conversations during its deliberations, and our engagement activities have produced valuable feedback that informs our decisions and our strategy.

The Board has established a process for stockholders to communicate with its members. Any stockholder or interested party who wishes to communicate with the Board as a whole, any of its committees, the independent directors, or any individual member of the Board may write to or email the Company at SiteOne Landscape Supply, Inc., 300 Colonial Center Parkway, Suite 600, Roswell, Georgia 30076, Attention: Briley Brisendine, Secretary, or boardofdirectors@siteone.com.

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. Of particular importance, we have prioritized enhancing the diversity of our Board, which is now comprised of a majority of directors who are women or from diverse backgrounds.

We have a highly-experienced Board that brings a range of relevant skills and qualifications to the Company. Key highlights of our Board composition include:

Board Independence						Board Diversity
86%			6 of 7 directors are independent			57%			4 of 7 directors are women or from diverse backgrounds 2 of 7 directors are women

Board Refreshment						Average Tenure
43%			3 of 7 directors have been added since 2017			4.5 Yrs			Average director tenure

In addition, our governance “best practices” include the following:


	Independent Committees			• All of our committees are composed solely of independent directors
	Empowered Lead Director			• Our independent directors elect our independent Lead Director • Our Lead Director has meaningful responsibilities including: — serving as liaison between independent directors and the Chairman; — chairing executive sessions of independent directors; and — consulting with the CEO on matters relating to management effectiveness and Board performance
	Board Leadership Evaluation and Succession Planning			• The Board annually evaluates the CEO’s performance • The Board annually conducts a rigorous review and assessment of the succession planning process for the CEO and other executive officers

TABLE OF CONTENTS

	Majority Vote Threshold			• Our Charter and By-laws may be amended by a majority vote of our stockholders
	Board & Committee Evaluations			• The Board and each of our committees conduct detailed annual self-evaluations
	Limits on Outside Board Service			• Outside directors are limited to service on four other public company boards • Currently, our CEO does not serve on any other public company boards
	Anti-Hedging/Pledging Policy			• Our insider trading policy prohibits our directors and executive officers from entering into pledging or hedging or monetization transactions designed to limit the financial risk of ownership of the Company’s securities • None of our directors or executive officers have any pledged SiteOne stock
	No “Poison Pill”			• We do not have a “poison pill” plan in place
	Executive Sessions			• The Board and Board committees meet regularly in executive session • In 2020, the independent directors met in executive session at each of the Board’s four quarterly meetings • At least once a year, the independent directors meet in an executive session with the CEO (without the other executive officers), with the Lead Director presiding at such sessions
	ESG Reporting and Transparency			• We publicly disclose a Responsibility Report aligned with the SASB framework

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, with clear and measurable goals and aggressive performance targets. To create a “pay for performance” environment, compensation is weighted toward at-risk compensation. Our long-term equity incentive program, which consisted of approximately 50% stock options, 25% restricted stock units (“RSUs”) and 25% performance stock units (“PSUs”) for the fiscal year ended January 3, 2021 (the “2020 Fiscal Year”), is designed to serve stockholders’ best interests in our sustained long-term performance by including performance-based awards, extended vesting schedules and meaningful stock ownership requirements. 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 metric highly correlated with stock price performance, with the actual number of shares granted subject to modification based on a three-year average absolute return on invested capital (“ROIC”) metric. PSUs are capped at 200% of target. 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. In addition, under our long-term equity incentive plan, underwater options are prohibited from being repriced without stockholder approval. We believe our named executive officers (“NEOs”) are compensated in a manner consistent with our strategy, competitive practice, sound compensation governance principles and alignment with stockholder interests.

For the 2020 Fiscal Year, base salaries for our NEOs were, in aggregate, between the 25th and 50th percentile of our peer group. The target for the Adjusted EBITDA metric under our annual incentive program was $224 million, an increase of more than 11.8% compared to the results for the fiscal year ended December 29, 2019 (the “2019 Fiscal Year”). Maximum payouts under the Adjusted EBITDA metric are capped at 250% of target, with the remaining components each capped at 150% of target. Due to our

TABLE OF CONTENTS

strong financial results that delivered double-digit growth, short-term 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) were 161% of target for the 2020 Fiscal Year as our Adjusted EBITDA exceeded target.

Compensation Best Practices:

What We Do

✔	Strong emphasis on performance-based compensation, with a significant portion of NEOs’ overall compensation tied to Company performance	✓	Human Resources and Compensation Committee, like all of the Board committees, comprised solely of independent directors
✔	Aggressive annual Adjusted EBITDA targets	✔	Rigorous measures tied to Company Net Promoter Score, Organic Daily Sales growth and individual strategic performance in the annual incentive plan and relative earnings growth and ROIC in the PSU awards
✔	Mix of short-term and long-term incentives, with performance awards representing a meaningful portion of long-term incentive pay	✔	Human Resources and Compensation Committee advised by independent compensation consultant who performs no other services to the Company
✔	Annual cash incentives for NEOs limited to 250% and 150% of target, for financial performance and other metrics, respectively	✔	Meaningful stock ownership requirements for executives and non-employee directors
✔	Double-trigger change-in-control cash severance benefits	✔	Robust clawback policy for incentive compensation paid to our executive officers, including the ability to clawback for fraud, misconduct, or illegal activity

What We Don’t Do

				Discount or reprice stock options						Allow hedging, pledging or short sales
				Gross up excise taxes that may become due upon a change in control						Guarantee incentive awards for executives
				Provide incentives that encourage excessive risk-taking						Provide perquisites for executives

Supporting Associates During COVID-19

We believe our employees, referred to by us as our “associates,”are our greatest asset and 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. During 2020 we put these values into action by implementing a comprehensive series of policies and practices to ensure the safety and well-being of our associates and their families during the COVID-19 pandemic. In addition, we provided meaningful bonuses to our frontline associates to recognize their outstanding contributions to our success in Fiscal Year 2020 in the face of unprecedented challenges.

Workforce-focused Initiatives

•

Quarantine Leave Policy: We created a new sick leave policy which allows associates who quarantine in compliance with CDC or local guidelines to stay home with pay. Through January 3, 2021, 1,254 associates had received quarantine pay.

TABLE OF CONTENTS

•

PTO Donation Program: We implemented a new PTO donation program which allows associates to donate PTO to other associates whose family members are impacted by COVID-19. Through January 3, 2021, 7,380 hours of PTO had been donated to provide support for 74 associates that have utilized the program.

Safety Measures

During the COVID-19 pandemic, we have implemented a number of safety measures, including the following:

•

Implemented a policy requiring all associates to wear face coverings inside branches, warehouses, offices, vehicles and outside in branch yards where six feet social distancing cannot be maintained

•

Asked customers to follow all state and local face covering legal requirements while in branches and offices

•

Reduced non-essential travel for associates and canceled events and company gatherings to help limit exposure

•

Asked associates not to travel to any high-risk areas identified by the CDC, and required those who do to remain away from the workplace for 14 days

•

Sanitized and disinfected branch counters and kiosks, equipment, restrooms and other shared areas on a regular basis

•

Equipped all locations with additional cleaning and sanitizing supplies and instruction on how to properly disinfect frequently touched surfaces

Special Payment for Frontline Associates

To reward exceptional performance during the challenging circumstances created by the COVID-19 pandemic, we made a special “thank you” payment in August 2020 to frontline branch associates who serve our customers. The aggregate payment totaled approximately $1.5 million. In addition, on March 5, 2021, we made a second special “thank you” payment to frontline branch associates to reward their ongoing work during the pandemic as well as their contributions to our strong performance in Fiscal Year 2020. In the aggregate, this second payment totaled approximately $400,000.

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 of SiteOne Landscape Supply, Inc., a Delaware corporation (referred to as “SiteOne,” the “Company,” “we,” “us,” or “our”), in connection with our Annual Meeting to be held on Wednesday, May 12, 2021, at 9:00 a.m., Eastern Time in a virtual meeting format only at www.virtualshareholdermeeting.com/SITE2021. 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 2020 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. If you would like to receive a paper copy of our proxy materials, at no charge, please write to SiteOne Landscape Supply, Inc., c/o Briley Brisendine, Executive Vice President, General Counsel and Secretary, 300 Colonial Center Parkway, Roswell, Georgia 30076.

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 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 March 31, 2021, 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 e-mail. 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 utilizing Notice and Access will save us the cost of printing and mailing documents to you and will reduce the impact of our Annual Meeting 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 16, 2021. At the close of business on that date, we had 44,392,274 shares of common stock issued and 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. 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.

TABLE OF CONTENTS

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.

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 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 two Class II nominees named in this Proxy Statement as Class II directors for a term expiring at the 2024 Annual Meeting of Stockholders.
	Proposal 2:			Ratify the selection of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ending January 2, 2022.
	Proposal 3:			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 two Class II nominees named in this Proxy Statement as Class II directors for a term expiring at the 2024 Annual Meeting of Stockholders.
	Proposal 2:			“FOR” the ratification of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ending January 2, 2022.
	Proposal 3:			“FOR” the non-binding advisory vote to approve executive compensation.
	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. If other matters requiring a vote of the stockholders arise, Doug Black and Briley Brisendine, the persons designated as proxies for the Annual Meeting, will vote the shares represented at the Annual Meeting in accordance with their judgment on those matters.

TABLE OF CONTENTS

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 constitutes presence in person for purposes of quorum. If a quorum is not present, the Annual Meeting may be adjourned from time to time until a quorum is present.

What votes are required to approve each of the proposals?

(1)

With regard to Proposal 1, stockholders may vote their shares “FOR” any or all of the nominees for director or may “WITHHOLD” their vote with respect to any or all of the nominees. With regard to Proposals 2 and 3 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 directors will not have an effect on the outcome of the election of directors in Proposal 1.

(2)

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. Brokers will only have discretionary authority to vote on Proposal 2, the ratification of the appointment of the independent registered public accounting firm. Broker non-votes will have no effect on Proposal 3 because broker non-votes will not be counted as shares entitled to vote on either 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.

(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 the vote when making future compensation decisions for our executive officers.

Stockholders as of the record date may attend and vote virtually at the Annual Meeting by logging in at www.virtualshareholdermeeting.com/SITE2021. To log in, stockholders (or their authorized representatives) will need the control number provided on their proxy card, voting instruction form or Notice. If you are not a stockholder or do not have a control number, you may still access the meeting as a guest, but you will not be able to participate.

Can i ask questions at the virtual Annual Meeting?

Stockholders as of our record date who attend and participate in our virtual Annual Meeting at www.virtualshareholdermeeting.com/SITE2021 will have an opportunity to submit questions live via the Internet during a designated portion of the meeting. These stockholders may also submit a question in advance of the Annual Meeting at www.proxyvote.com. In both cases, stockholders must have available their control number provided on their proxy card, voting instruction form or Notice. While we intend to answer questions generally in the order in which they are received, only questions pertinent to meeting matters will be answered during the Annual Meeting, subject to time constraints. Questions regarding personal matters, including those related to employment, product or service issues, or suggestions for product innovations, are not pertinent to meeting matters and therefore will not be answered. Questions that are substantially similar may be grouped and answered together to avoid repetition.

If we are unable to answer your question during the Annual Meeting due to time constraints, you are encouraged to contact our Investor Relations department at investors@siteone.com.

TABLE OF CONTENTS

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” the ratification of Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm for the 2021 Fiscal Year and “FOR” the proposal regarding the advisory vote approving executive compensation.

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 voting at the Annual Meeting. Please note, however, that if you are a beneficial owner of shares, you must contact your nominee to change your vote or obtain a proxy to vote your shares if you wish to cast your vote at the Annual Meeting.

Who will count and certify the votes?

Representatives of 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 $132,000. 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 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.

PROPOSAL 1: ELECTION OF DIRECTORS

Our stockholders will be asked to elect Doug Black and Jack Wyszomierski, both of whom are currently serving on the Board, as Class II directors to each serve for a three-year term expiring at the 2024 Annual Meeting of Stockholders or until their respective successors have been elected and qualified, subject to their earlier death, resignation, retirement, disqualification or removal:

Name			Position with SiteOne
Doug Black			Chairman and Chief Executive Officer
Jack Wyszomierski			Director

Our Board continually assesses and evaluates its composition, taking into account, among other things, the experience, skills, background and diversity of its members. The relevant experiences, qualifications, attributes and skills of each nominee that led the Board to recommend them as a nominee for director are described in the section entitled “— Nominees for Director and Continuing Directors” beginning on page 15 below. The Nominating and Corporate Governance Committee has reviewed the qualifications of each of the nominees and has recommended to the Board that each nominee be submitted to a vote at the Annual Meeting.

Both of the nominees have indicated their willingness to serve, if elected. However, if either nominee should be unable or unwilling to serve, the Board may designate a substitute nominee, in which case the persons designated as proxies will cast votes for the election of such substitute nominee. In lieu of designating a substitute nominee, the Board, in its discretion, may reduce the number of directors, or allow the vacancy to remain open until a suitable candidate is located and nominated.

The Company did not receive any stockholder nominations for director. Proxies cannot be voted for more than the number of nominees named in this Proxy Statement.

Required Vote

Director nominees are elected by a plurality of the votes cast at the Annual Meeting, meaning that the nominees receiving the highest number of “FOR” votes will be elected.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” EACH OF THE NOMINEES NAMED ABOVE FOR ELECTION AS A DIRECTOR.

TABLE OF CONTENTS

CORPORATE GOVERNANCE

The Board is committed to strong corporate governance. 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, ESG 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, charters of each committee of the Board and our Responsibility Report, which details our ESG initiatives and progress.

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

Board Structure

The Board currently consists of seven 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 three directors in Class III. The terms of the directors in Classes I, II and III expire at the annual meetings in 2023, 2024 and 2022, respectively. We believe that our classified board structure provides protection against opportunistic attempts to control or influence the Company, including those that could deprive our stockholders of value or advance short-term agendas. During our stockholder outreach programs conducted in the fall of 2018, 2019 and 2020, our investors generally expressed a positive or constructive view of our classified board structure at this point in time. Only one of the stockholders we engaged with this year expressed an unfavorable view of our classified board structure.

The 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 and Selection of 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 members are considered for nomination for re-election, the Nominating and Corporate Governance Committee also takes into consideration their prior Board contributions, performance and meeting attendance records. Each director candidate (including candidates for re-election) is carefully evaluated to ensure that other existing and planned future commitments will not materially interfere with his or her responsibilities as a director of our Company. Our director biographies above, as well as the skills matrix below, highlight the experiences and qualifications that were among the most important to the Nominating and Corporate Governance Committee and the Board in concluding that the nominee should serve as a director of the Company.

TABLE OF CONTENTS

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. Set forth below is the Director Skills Matrix that the Nominating and Corporate Governance Committee reviews at its quarterly meetings in connection with discussions regarding potential new directors.

The Nominating and Corporate Governance Committee may use a variety of sources to identify candidates, including recommendations from stockholders, current directors, current executives, external consultants, and others. Evaluations of prospective candidates typically include a review of the candidate’s background and qualifications by the Nominating and Corporate Governance Committee, interviews with the members of management, the committee and other Board members, and discussions of the committee and the full Board.

The Nominating and Corporate Governance Committee considers stockholder-proposed director candidates on the same basis as recommendations from other sources. Stockholders who want to recommend a director candidate to the Nominating and Corporate Governance Committee may do so by submitting the name of the prospective candidate in writing to the following address: 300 Colonial Center Parkway, Suite 600, Roswell, Georgia 30076, Attention: Briley Brisendine, Secretary. Submissions should describe the experience, qualifications, attributes and skills that make the prospective candidate a suitable director nominee. Our By-laws set forth the requirements for direct nomination by a stockholder of persons for election to the Board. These requirements are described under “General Information — Stockholder Proposals and Nominations for Director at the 2022 Annual Meeting” on page 60.

Director Independence

The Board has determined, after considering all of the relevant facts and circumstances, that Messrs. Diaz, Douglas, Dunbar and Wyszomierski and Mses. Drake and Isbell are “independent” as defined under New York Stock Exchange (“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

The Board is led by our CEO and Chairman, 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

TABLE OF CONTENTS

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 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 independent members of the Board. William W. Douglas, III 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 independent directors, chairs executive sessions of 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 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 with an empowered and independent Lead Director, provide the appropriate leadership and Board oversight of our Company and facilitate effective functioning of both the Board and the management team.

Meetings of the Board and Attendance at the Annual Meeting

The Board held four meetings during the 2020 Fiscal Year, three of which were held virtually due to COVID-19 safety protocols. Each of our current directors attended all of the meetings of the Board and any committees of which he or she was a member held during the 2020 Fiscal Year. Directors are encouraged to attend our annual meetings, and all of our directors attended our 2020 Annual Meeting of Stockholders.

Executive Sessions

Executive sessions, which are meetings of the 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 independent directors meet with the 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

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. In addition, we recently updated our clawback policy for incentive compensation, equity compensation and performance-based compensation, paid to our executive officers, reflected in the guidelines to include the ability to clawback for fraud, misconduct or illegal activity. 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.

Environmental and Social Responsibility

We are committed to environmental and social responsibility, and work collaboratively with customers, associates, suppliers and other stakeholders to promote environmentally sustainable and socially responsible business practices. Our Board, specifically the Nominating and Corporate Governance Committee, oversees

TABLE OF CONTENTS

our environmental stewardship and corporate responsibility initiatives and is committed to supporting our efforts to operate as a good neighbor in our communities. In addition to our commitment to ongoing, organization-wide sustainability improvement, 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 inaugural Responsibility Report in 2020, which details our programs and progress across a number of important human capital and sustainability topics. In addition, our Responsibility Report follows the SASB framework and includes the disclosure of quantitative metrics relevant to our industry. In the coming years, we will continue to dedicate resources to measuring, reporting on, and improving our sustainability efforts.

Our Responsibility Report, as well as several other corporate policies, including a Human Rights Policy, a Supplier Code of Conduct and an Environmental Policy are available on our website at https://investors.siteone.com/corporate-governance/governance-documents.

Code of Conduct and Financial Code of Ethics

We have a Financial Code of Ethics that applies to the 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 each address matters such as conflicts of interest, confidentiality, fair dealing and compliance with laws and regulations. The BCCE contains a 24-hour Compliance and Ethics Hotline to anonymously report compliance or ethics concerns. Copies of the Financial Code of Ethics and the BCCE are available at our website at http://investors.siteone.com/corporate-governance.

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.

The following table shows the current members of each committee, as well as the number of meetings held during the 2020 Fiscal Year. At this time, the Board does not expect any changes to the composition of the committees for the 2021 Fiscal Year.

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

TABLE OF CONTENTS

Committee 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 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 on our website at http://investors.siteone.com/corporate-governance.

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 from Mr. Wyzomierski’s service on other audit committees and experience as a chief financial officer.

Human Resources and Compensation Committee

The Human Resources and Compensation Committee is responsible, among its other duties and responsibilities, for reviewing and approving all forms of compensation to be provided to, and employment agreements with, the executive officers and directors of our company and its subsidiaries (including the CEO), establishing the general compensation policies of our Company and its subsidiaries and reviewing, approving and overseeing the administration of the associate benefits plans of our Company and its subsidiaries. The Human Resources and Compensation Committee also periodically reviews management development, diversity and succession plans. In May 2019, the Board adopted revisions to the committee’s charter, which memorialized the committee’s responsibility for oversight of the Company’s human capital metrics including diversity, pay equity, promotions, turnover and other metrics. The charter of the Human Resources and Compensation Committee is available on our website at http://investors.siteone.com/corporate-governance.

The members of the Human Resources and Compensation Committee are Ms. Isbell (Chair) and Messrs. Dunbar and Diaz. The Board has determined that Messrs. Dunbar and Diaz and Ms. Isbell are independent directors.

The Human Resources and Compensation Committee has the authority to retain compensation consultants, outside counsel and other advisers. During the 2020 Fiscal Year, the Human Resources and Compensation Committee engaged Frederic W. Cook & Co. (“FW Cook”) to advise it on executive compensation program design matters and to prepare market studies of the competitiveness of components of the Company’s compensation program for its senior executive officers, including the NEOs and non-employee directors. The Human Resources and Compensation Committee performed an assessment of FW Cook’s independence to determine whether the consultant is independent, taking into account FW Cook’s executive compensation consulting protocols to ensure consultant independence and other relevant factors. Based on that assessment, the Human Resources and Compensation Committee determined that FW Cook’s work has not raised any conflict of interest and FW Cook is independent.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is responsible, among its other duties and responsibilities, for identifying and recommending candidates to the Board for election to the Board, reviewing the composition of the Board and its committees, developing and recommending to the Board corporate governance guidelines and policies that are applicable to us, and overseeing Board evaluations.

TABLE OF CONTENTS

The Nominating and Corporate Governance Committee also oversees and monitors significant issues affecting our culture, including our handling of ESG issues. The charter of the Nominating and Corporate Governance Committee is available on our website at http://investors.siteone.com/corporate-governance.

In September of 2020, the Board appointed Ms. Drake as a new member of the Nominating and Corporate Governance Committee. The Board believes that Ms. Drake’s extensive experience supporting the sustainability initiatives of Equity LifeStyle Properties will benefit the Nominating and Corporate Governance Committee in its oversight of the Company’s ESG efforts. At the same time, Mr. Douglas resigned from the Nominating and Corporate Governance Committee to allow him to devote more time to his duties as the Board’s Lead Director. The current members of the Nominating and Corporate Governance Committee are Mr. Wyszomierski (Chair) and Mses. Drake and Isbell. The Board has determined that Mr. Wyszomierski and Mses. Drake and Isbell are independent directors.

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.

Whistleblower Procedure

In addition to our BCCE described above, the Audit Committee has established a separate whistleblower procedure for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or 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

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 and cybersecurity. The Audit Committee meets regularly with our General Counsel. The Human Resources and Compensation Committee evaluates risks arising from our 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.

TABLE OF CONTENTS

Compensation Risk Assessment

In March 2021, 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 and Retention Guidelines

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, and has adopted a Non-Employee Director Equity Ownership Policy for non-employee directors. These policies limit our CEO, Covered Executives (as defined below) and non-employee directors from selling shares of common stock 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 annual cash retainer for non-employee directors. For more information about our stock ownership and retention guidelines, see the discussion in the Compensation Discussion and Analysis under the heading “Executive Officer Stock Ownership and Retention Guidelines” on page 44 and under “Director Compensation — Non-Employee Director Stock Ownership and Retention Guidelines” on page 56. Currently, each non-employee director is in compliance with the Non-Employee Director Stock Ownership and Retention Guidelines and our CEO and each Covered Executive is in compliance the Executive Officer Stock Ownership and Retention Guidelines.

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.

Board and Committee Evaluations

The Board conducts a 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 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 operates in the most efficient and effective manner possible.

Conflicts of Interest

Our BCCE and our Corporate Governance Guidelines govern our conflicts of interest policy. The BCCE requires 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 requires all conflicts of interest between the Company and its associates to be

TABLE OF CONTENTS

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 Party Transactions

See “General Information — Certain Relationships and Related Party Transactions” on page 59 for a discussion of our policies and procedures for related person transactions.

Director Change in 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 and Management Development

Succession planning and talent development are important at all levels within our organization, and accordingly, succession planning and management development are discussed regularly by the Board and the 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 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 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

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

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 to the Board after their 72nd birthday, the full Board may nominate candidates over 72 for election or reelection in special circumstances.

PROPOSAL 2: RATIFICATION OF SELECTION OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Deloitte audited our consolidated financial statements for the 2020 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 to be well qualified and has appointed Deloitte as our independent registered public accounting firm to audit our consolidated financial statements for the year ending January 2, 2022.

This proposal asks you to ratify the Audit Committee’s appointment of Deloitte 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’s 2020 performance as part of its consideration of whether to re-appoint Deloitte as our independent registered public accounting firm. As part of this review, the Audit Committee considered, among other things:

•

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’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’s staff and national reach;

•

the appropriateness of Deloitte’s fees; and

•

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

The Audit Committee recognized the ability of Deloitte 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 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 is independent and objective and that it is in the best interests of the Company and its stockholders to appoint Deloitte to serve as the Company’s independent registered accounting firm for 2021. Consequently, the Audit Committee has appointed Deloitte as the Company’s independent registered public accounting firm for 2021, 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 but may, nonetheless, retain Deloitte 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 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.

Audit Committee Matters

Fees Paid to Deloitte

The following table presents, for the 2020 Fiscal Year and 2019 Fiscal Year, fees billed to the Company by Deloitte for the audit of our annual financial statements, audit-related services and all other services. All services provided by Deloitte were approved by the Audit Committee in conformity with the Audit Committee’s pre-approval policy discussed below.

	2020			2019
Audit fees(1)		$	1,470,000		$	1,410,000
Audit-related fees(2)			98,500			57,500
All other fees(3)			3,790			3,408
Total Fees			1,572,290		$	1,470,908

(1)

Audit fees are fees we paid Deloitte for the audit of our consolidated financial statements included in our Annual Report on Form 10-K, review of the financial statements included in our Quarterly Reports on Form 10-Q and services in connection with statutory and regulatory filings.

(2)

Audit-related fees for the 2020 Fiscal Year and 2019 Fiscal Year consisted of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and were not reported under “Audit Fees.” Audit-related fees for 2020 also include fees related to our filings on Forms S-3 and S-8.

(3)

All other fees are fees for any products and services provided by Deloitte not included in the first 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 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 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 during 2020 and 2019 were approved in advance by the Audit Committee pursuant to the pre-approval policy.

TABLE OF CONTENTS

Report of the Audit Committee

Management of the Company is responsible for the preparation, presentation and integrity of the Company’s consolidated financial statements, maintaining a system of internal control and having appropriate accounting and financial reporting principles and policies.

PROPOSAL 3: ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

We provide our stockholders with the annual 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 more than 96% say on pay support each year, including over 98% at last year’s Annual Meeting of Stockholders.

The Board and Human Resources and Compensation Committee are dedicated to ensuring that our executive 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 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 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 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:

“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 2021 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 35 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 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.

Virtual attendance at the Annual Meeting constitutes presence in person for purposes of the required vote.

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.

TABLE OF CONTENTS

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

In this section we provide information about 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 2020 Fiscal Year. Our NEOs for the 2020 Fiscal Year were:

•

Doug Black, Chief Executive Officer

•

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

•

Briley Brisendine, Executive Vice President, General Counsel and Secretary

•

Scott Salmon, Executive Vice President, Strategy and Development

•

Joseph Ketter, Executive Vice President, Human Resources

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 over 98% 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 takes seriously 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.

TABLE OF CONTENTS

Compensation Best Practices

What We Do

✔	Strong emphasis on performance-based compensation, with a significant portion of NEOs’ overall compensation tied to Company performance	✔	Human Resources and Compensation Committee, like all of the Board committees, comprised solely of independent directors
✔	Aggressive annual Adjusted EBITDA targets	✔	Rigorous measures tied to Company Net Promoter Score, Organic Daily Sales growth and individual strategic performance in the annual incentive plan and relative earnings and ROIC in the PSU awards

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 2020 Fiscal Year, the Human Resources and Compensation Committee engaged FW Cook as an 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.

To assist in evaluating our compensation program for 2020, in August 2019, the Human Resources and Compensation Committee reviewed our Company’s industry peer group, considering among other factors,

TABLE OF CONTENTS

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. 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

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

In relation to the peer group, our revenues and net income were between the 25th percentile and median and our market capitalization was between the median and 75th percentile of the peer companies, respectively, at the time that the Human Resources and Compensation Committee approved the peer group.

Executive Management

Certain members of executive management 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 may provide input on financial goals. Our CEO, Executive Vice President, Human Resources, and General Counsel generally attend Human Resources and 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 base salaries provide a fixed level of compensation, our short-term 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 cash incentive program includes Adjusted EBITDA, Company Net Promoter Score (“NPS”), Organic Daily Sales growth and other individualized strategic performance targets. The Adjusted EBITDA component of our annual incentive awards, 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. During the first half of Fiscal Year 2020, our Human Resources and Compensation Committee evaluated making adjustments to certain targets and calculations under our short-term cash-incentive plan to neutralize the extraordinary impacts of the COVID-19 pandemic, particularly its impact on our business in the second quarter. However, given the developing recovery in our markets, our results relative to the original performance goals and the Board’s focus on performance-based compensation, the Human Resources and Compensation Committee ultimately elected not to make any adjustment to our 2020 performance targets or to apply positive discretion to increase the funded level of short-term incentive payout. The Human Resources and Compensation Committee did elect to decrease the Adjusted EBITDA threshold and target goals by $1.5 million with respect to the August 2020 special “thank-you” payment to avoid penalizing Company associates eligible for the annual cash incentive program. Our long-term equity inventive program provides for extended vesting schedules and prohibits repricing of underwater options and includes PSUs with three-year relative and absolute performance criteria and capped payouts at 200% of target. Lastly, while we provide customary benefits as discussed below, we provide limited perquisites to our executives.

TABLE OF CONTENTS

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 2020 Fiscal Year, our NEOs’ target total direct compensation, which includes base salary, target short-term cash incentive and long-term equity awards, approximated the median (i.e., 50th percentile) of peer group practice.

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, Organic Daily Sales growth and individual performance goals
Long-Term Equity Awards			• To align executive and stockholder interests, create “ownership culture,” provide retention incentives 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 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 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 2020, the Human Resources and Compensation Committee approved salary increases for each of our NEOs in the range of 2.9% to 8.1% to move salaries toward the 50th percentile of our peer group. The base salaries paid to each of our NEOs for our 2020 Fiscal Year are shown in the “Summary Compensation Table” on page 46.

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 Human Resources and Compensation Committee and CEO (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.

TABLE OF CONTENTS

All of our NEOs were eligible in the 2020 Fiscal Year to receive cash incentive awards based on the achievement of pre-established annual Company financial and performance metrics approved by the Human Resources and Compensation Committee. For the 2020 Fiscal Year, each NEO had a target incentive opportunity expressed as a percentage of his salary paid during the year. The threshold, target and maximum percentages of base salary and actual percentages of target for our NEOs for the 2020 Fiscal Year were as follows:

	Threshold(1)		Target(1)		Maximum(2)		Actual Percentage of Target(2)
Doug Black		62.5%		125%		220%		151%
John Guthrie		30%		60%		220%		152%
Briley Brisendine		30%		60%		220%		154%
Scott Salmon		30%		60%		220%		142%
Joseph Ketter		30%		60%		220%		153%

Expressed as a percentage of base salary. For the 2020 Fiscal Year, each of the various components of the annual incentive awards were subject to a cap, as set forth below.

(2)

Expressed as a percentage of the target annual incentive opportunity.

The Human Resources and 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 Human Resources and Compensation Committee in the beginning of the year. The Adjusted EBITDA target goal of $224 million represented an increase of more than 11% compared to 2019 actual performance of $201 million, after giving effect to the inclusion of acquisitions completed during the first half of the 2020 Fiscal Year. In order to ensure our team continues to deliver outstanding customer service, the Human Resources and Compensation Committee also utilized Company-wide NPS as a component of each NEO’s annual incentive award, with a target score set at 72.5 and a maximum payout (150% of target) for a score of 80 or higher. In addition, in order to drive continued sales growth, the Human Resources and Compensation Committee also utilized Organic Daily Sales growth as a component of each NEO’s annual incentive award. The Human Resources and Compensation Committee subjectively assessed Mr. Black’s achievement with respect to the strategic performance goals and, with respect to 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 2020 Fiscal Year performance metrics for each NEO, expressed as a percentage of each NEO’s 2020 Fiscal Year total incentive opportunity.

	Adjusted EBITDA(1)			Company NPS(2)						Organic Daily Sales Growth(2)						Strategic Performance(2)						Total Target STI
	70%					10%						10%						10%						100%

(1)

The Adjusted EBITDA component of the annual incentive opportunity is capped at 250% of target.

(2)

The Company NPS, Organic Daily Sales growth and Strategic Performance components of the annual incentive opportunity are each capped at 150% of target. Safety was included in the Strategic Performance component for Messrs. Black, Brisendine and Ketter.

TABLE OF CONTENTS

The following table shows the threshold, target, and actual performance levels, along with the multiple of target incentive opportunity, for the Adjusted EBITDA component of the 2020 Fiscal Year incentive opportunities for our NEOs.

Adjusted EBITDA(1)	Level of Achievement(1)(2)(3)(4)	Multiple of Target Opportunity
Threshold	$202 million		50%
Target	$224 million		100%
Stretch	$252 million		150%
Maximum	$308 million		250%
Actual	$258 million		161%

(1)

Adjusted EBITDA was calculated using EBITDA for the Company for the 2020 Fiscal Year, as further adjusted for items such as stock-based compensation expense, (gain) loss on sale of assets, 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 Human Resources and Compensation Committee in February 2020, in August 2020, the Human Resources and Compensation Committee increased threshold and target goals by $8.1 million each to take into account anticipated Adjusted EBITDA contributions from acquisitions completed during the first half of the 2020 Fiscal Year. Acquisitions completed during the second half of the 2020 Fiscal Year were excluded from the calculation of Adjusted EBITDA for purposes of determining annual incentive compensation.

(3)

To reward exceptional performance during the COVID-19 pandemic, the Human Resources and Compensation Committee approved a special “thank you” payment awarded to frontline branch associates. The Human Resources and Compensation Committee decreased the Adjusted EBITDA threshold and target goals by $1.5 million to avoid penalizing Company associates eligible for the annual cash incentive program for the effect of this special payment on Adjusted EBITDA.

(4)

The Adjusted EBITDA weighted performance multiplier is determined by linear interpolation of the percentage achievement between threshold and target 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 2020 Fiscal Year incentive opportunities for our NEOs.

Company NPS(1)	Level of Achievement		Multiple of Target Opportunity
Threshold		62		50%
Target		72.5		100%
Maximum		80		150%
Actual		74.8		115%

(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.

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 2020 Fiscal Year incentive opportunities for our NEOs.

Threshold		2.7%		50%
Target		4.7%		100%
Maximum		6.7%		150%
Actual		7.5%		150%

“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.

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. These individual criteria were related to specific individual categories of performance measures, as described below.

			Individual Performance Categories
Mr. Black			• Improved safety metrics, Company financial plan achievement, diversity improvement, team development
Mr. Guthrie			• Finance team development and strategic planning, field reporting and tracking, financial reporting
Mr. Brisendine			• Company safety, corporate governance oversight and execution, risk management enhancements, field operations support
Mr. Salmon			• Acquisition growth, integration and performance; National Accounts sales and gross margin growth
Joseph Ketter			• Company safety, recruiting and onboarding, associate training/development, diversity improvement

Achievement of the Adjusted EBITDA, Company NPS, Organic Daily Sales growth and the individual performance measures, taken together, resulted in short-term annual cash incentive awards for the 2020 Fiscal Year of $1,623,182 to Mr. Black, $365,873 to Mr. Guthrie, $401,763 to Mr. Brisendine, $310,049 to Mr. Salmon and $313,161 to Mr. Ketter. The award paid to each of our NEOs is shown in the “Summary Compensation Table” on page 46 under the “Non-Equity Incentive Plan Compensation” column.

Long-Term Equity Incentives

Our 2020 Omnibus Equity Incentive Plan (the “2020 Plan”) serves as the primary vehicle for providing equity incentives to our associates and directors. Prior to obtaining shareholder approval of the 2020 Plan at our 2020 Annual Meeting, we granted equity awards under the 2016 Omnibus Equity Incentive Plan (the “2016 Plan”). The 2020 Plan replaced the 2016 Plan, under which no additional awards will be granted; however, outstanding awards granted under the 2016 Plan will remain outstanding and will continue to be administered in accordance with the terms of the 2016 Plan and the applicable award agreements.

The Human Resources and Compensation Committee began making annual equity grants to our executives in 2017 as part of our compensation program. In addition, the Human Resources and

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 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 2016 Plan and the 2020 Plan during the 2020 Fiscal Year, see the “Grants of Plan-Based Awards for 2020 Fiscal Year” table on page 47.

Prior to our IPO and the adoption of the 2020 Plan and 2016 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 other than Mr. Salmon, who was hired post-IPO, 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 2020 Fiscal Year End” on page 49 and the discussion under “Options Granted under the Stock Incentive Plan” on page 48 below.

Awards Granted During 2020 under the 2016 Plan

To create a “pay-for-performance” environment, compensation is weighted toward at-risk compensation. Our long-term equity incentive program, which consisted of approximately 50% stock options, 25% RSUs and 25% PSUs for the 2020 Fiscal Year, is designed to serve stockholders’ best interests through sustained long-term performance.

[MISSING IMAGE: tm219017d2-pc_awardmic4c.jpg]

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 return on invested capital (“ROIC”) modifier, as set forth below. The “Performance Period” for the PSUs awarded in February 2020 is a three-year period commencing December 30, 2019 and ending January 1, 2023. Vesting of PSUs is contingent upon each NEO’s continued employment, subject to certain exceptions as set forth in the PSU agreement.

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 48 and under “Potential Payments Upon Termination or Change in Control” on page 50. 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 48. In addition, we have entered into severance agreements with Messrs. Guthrie, Brisendine, Salmon and Ketter, 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 without 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, Brisendine, Salmon and Ketter” on page 51.

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, 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. Prior to the COVID-19 pandemic, certain of our NEOs and their spouses attended an annual customer event of which the Company covered certain expenses for the NEOs’ spouses as an additional benefit.

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 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

TABLE OF CONTENTS

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 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 FASB 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 executive officer who reports directly to the CEO (each, a “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. During the 2019 Fiscal Year, the Human Resources and Compensation Committee amended the Executive Officer Ownership Policy to increase the CEO holding requirement (from 5x base salary to 6x base salary) and exclude the value of in-the-money options from the ownership calculation.

The CEO and each Covered Executive are required to hold 50% of shares acquired as a result of 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 55.

Letter from the Human Resources and Compensation Committee

Dear Fellow Stockholders,

In May of 2019, the Committee amended its charter document to reflect its existing oversight of matters beyond compensation and changed the Committee’s name to the Human Resources and Compensation Committee. At each of its quarterly meetings, the Committee reviews a number of human capital metrics, including metrics related to diversity, pay equity, associate development and associate turnover. In Fiscal Year 2020, the Committee continued to enhance its emphasis on diversity and inclusion and associate engagement with the introduction of an associate resource group to support our Black associates and the formation of a Diversity and Inclusion Council to assist our executive leadership with the creation and execution of our diversity and inclusion strategy. In addition, the Committee also closely monitored the Company’s response to the COVID-19 pandemic that prioritized the safety of our associates and customers.

The Committee continues to closely evaluate the Company’s linkage between pay and performance, carefully considering feedback from our stockholders. We remain committed to considering stockholder views as we continue this important work.

Human Resources and Compensation Committee Report

The Human Resources and Compensation Committee has reviewed and discussed with management the Company’s Compensation Discussion and Analysis, and based on such review and discussions, has recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement and incorporated by reference into the Company’s Annual Report on Form 10-K for the 2020 Fiscal Year.

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 Company’s Human Resources and 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 his offer of employment, the Company also entered into a letter agreement with Mr. Brisendine. Under the letter agreement, Mr. Brisendine is entitled to a base salary to be determined annually by the Human Resources and Compensation Committee and is eligible for payment of an annual cash bonus. The target annual cash bonus for Mr. Brisendine is equal to 60% of his base salary, subject to meeting performance goals set annually. The target cash bonus for Mr. Brisendine of 60% of base salary for the 2020 Fiscal Year is consistent with the target cash bonus for Fiscal Year 2019. In addition, each of Messrs. Brisendine, Guthrie, Salmon and Ketter 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 under the Stock Incentive Plan

The Stock Incentive Plan and an employee stock option agreement govern the stock options granted to our NEOs prior to the adoption of the 2016 Plan, including, 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 “— Elements of Our Executive Compensation Program — Long-Term Equity Incentives” on page 41.

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)

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 2020, units granted on February 17, 2017 vested on February 17, 2020, units granted on February 14, 2018 vested on February 14, 2020, units granted on February 6, 2019 vested on February 6, 2020 and units granted on March 11, 2019 vested on March 11, 2020, and the closing stock price on those dates was $105.71, $105.71, $101.32 and $86.88, respectively.

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, (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 without 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

TABLE OF CONTENTS

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, Brisendine, Salmon and Ketter

The Company is party to a separation benefits agreement with each of Messrs. Guthrie, Brisendine, Salmon and Ketter 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, Brisendine, Salmon and Ketter operate with a “double trigger” in the event of a change of control, meaning severance payments do not occur unless the 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.”

“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 Human Resources and 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;

TABLE OF CONTENTS

•

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.

2020 Plan and 2016 Plan

For the options and RSUs granted in 2017, 2018, 2019 and 2020 under the 2016 Plan and future awards under the 2020 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 in 2019 or 2020, 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 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, 2019 and 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 (with the exception of PSUs granted in 2020 for which 67% of the PSUs will vest); and (z) if retirement occurs in year three of the performance period, then 100% of the PSUs will vest.

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 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.

For the options granted in 2016 under the 2016 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 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

TABLE OF CONTENTS

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 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;

•

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

•

the consummation 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;

•

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);

•

the approval of a plan of complete liquidation or dissolution by our stockholders.

Our IPO did not constitute a change in control for purposes of the equity plans.

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 deferred share units (“DSUs”) 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 $105,000 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.

Mr. Diaz elected to receive 100% of his cash compensation in the form of DSUs and, accordingly, received 845 DSUs, as payment in lieu of his cash compensation.

Reflects the grant date fair value of 1,228 DSUs granted to each director on May 13, 2020 and 312 DSUs, 210 DSUs, 185 DSUs and 138 DSUs granted to Mr. Diaz on March 27, 2020, June 26, 2020, September 25, 2020 and December 31, 2020, respectively. 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.

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, the 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 2020 Fiscal Year. No member of the Human Resources and Compensation Committee during the 2020 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 Human Resources and 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 2020 Fiscal Year.

Includes 1,145,050 stock options, 40,784 RSUs, 35,598 PSUs and 40,981 DSUs granted to officers and directors pursuant to the 2020 Plan, 2016 Plan and the Stock Incentive Plan.

CEO Pay Ratio

For the 2020 Fiscal Year: (i) the total compensation of our median employee (excluding Mr. Black, our CEO) was $50,640; and (ii) the annual total compensation of Mr. Black, our CEO, was $4,875,559. Based on this information, the ratio of the annual total compensation of our CEO to the median employee is 96.3 to 1.

Methodology

During the 2020 Fiscal Year, there were no changes to our associate population or 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 2019 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 December 31, 2019, which consisted of a total of 4,615 associates, 4,536 of whom were located in the United States and 79 of whom were located in Canada.

Compensation Measure

We use a variety of pay elements to structure the compensation arrangements of our associates, including an annual cash incentive award plan for a portion of our full-time associates, commissioned-based incentive compensation for associates in our various sales organizations, and hourly compensation for those associates 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 December 31, 2019. We included all permanent associates, including new associates who were hired during the 2019 Fiscal Year but did not work for the Company for the entire fiscal year. For our Canadian associates, we converted their local CAD to USD using the 2019 annual exchange rate of 0.76. We did not make any cost-of-living adjustments in identifying the median employee.

Median Employee

Using the methodology describe above we determined that during the 2019 Fiscal Year our median employee was a full-time, salaried associate located in the United States. Our median employee’s total annual compensation, calculated using the same methodology we used in calculating Mr. Black’s annual total compensation for the 2020 Fiscal Year, was $50,640. This represents an increase of 5.5% over our median employee’s 2019 Fiscal Year total compensation of $47,980.

With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of our 2020 Summary Compensation Table on page 46.

GENERAL INFORMATION

Stock Ownership

The following table sets forth information as of March 16, 2021 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 44,392,274 shares of our common stock outstanding as of March 16, 2021.

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.
