REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Benefits Committee, Plan Administrator

and Plan Participants of the SiteOne Savings and Investment Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the SiteOne Savings and Investment Plan (the Plan) as of December 31, 2023 and 2022, and the related statement of changes in net assets available for benefits for the year ended December 31, 2023, and the related notes and schedule (collectively referred to as the financial statements). In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2023 and 2022, and the changes in net assets available for benefits for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risk of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental information in the accompanying Schedule of Assets (Held at End of Year) as of December 31, 2023 has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

1.    Description of Plan

The following description of the SiteOne Savings and Investment Plan ("the Plan") provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan under Section 401(k) of the Internal Revenue Code covering substantially all employees of SiteOne Landscape Supply, Inc. and its subsidiaries ("the Company"), except for collective bargaining employees, leased employees, non-resident aliens with no U.S. source income, and seasonal employees. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA").

From time to time, the Company enters into strategic acquisitions in an effort to better service existing customers and to attract new customers. The Company’s policy is to have the seller terminate any benefit plans that they had in place. Any onboarded employees are offered participation in the Plan in accordance with the Plan’s eligibility provisions.

On December 23, 2022, Congress passed the Consolidated Appropriations Act of 2023 which included SECURE Act 2.0. SECURE Act 2.0 contains approximately 90 new retirement provisions, with varying effective dates through 2027. Since SECURE Act 2.0 provisions include both required and optional elements, the plan administrator will determine the optional provisions to elect and amend the Plan document accordingly. Most of the significant provisions will become effective in 2024 and thereafter. Accordingly, there is no material impact to the Plan’s 2023 financial statements.

Contributions

Eligible employees are automatically enrolled into the Plan after 30 days of employment unless the employee elects otherwise. Pre-tax contributions are withheld at 3% of eligible compensation and increased by 1% each year until it reaches 50% of eligible compensation unless the employee elects differently. Each year, participants may make pre-tax or Roth after-tax contributions up to 50% of eligible compensation, as defined by the Plan document, not to exceed a maximum of $22,500 for the Plan year. Participants who have attained age 50 before the end of the Plan year are eligible to make catch-up contributions of up to $7,500 for the Plan year. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. The Company may make discretionary matching contributions. For the year ended December 31, 2023, the Company made matching contributions equal to 120% of the first 2% of the participant’s eligible compensation plus 40% of the next 4% of the participant’s eligible compensation. No allowance for credit losses has been recorded as of December 31, 2023 or 2022.

Participant Accounts

Each participant’s account is credited with the participant’s contributions and any Company matching contributions as well as allocations of Plan earnings and losses and charged with certain administrative expenses. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account. Participants direct the investment of their contributions into various investment options offered by the Plan. The Plan currently offers mutual funds, Company stock, a money market fund, self-directed brokerage accounts, and collective investment trust funds as investment options for participants.

Notes to Financial Statements (continued)

Vesting

Participants are vested immediately in their voluntary contributions plus actual earnings and losses thereon. A participant is 100% vested in employer matching contributions after three years of credited service if employed after December 23, 2013. If employed prior to that date, a participant is always 100% vested in the employer matching contribution. Certain matching contributions from prior employers of merged plans are subject to vesting schedules in place at the time of the merger.

Notes Receivable from Participants

Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance. The notes are secured by the balance in the participant’s account and bear interest at a rate commensurate with prevailing rates as determined by the plan administrator. All notes currently bear rates ranging from 4.25% to 10.50%. Principal and interest is paid ratably through payroll deductions.

Payment of Benefits

On termination of service due to separation, death, disability, or retirement, a participant may elect to receive an amount equal to the value of the participant’s vested interest in his or her account in a lump-sum amount. The Plan also permits in-service distributions for participants that have attained age 59 ½. Hardship distributions are permitted upon demonstration of a financial hardship, as defined by the Plan document.

Forfeited Accounts

Forfeitures may be used to reduce Company contributions or Plan expenses. At December 31, 2023 and 2022, forfeited non-vested account balances amounted to $78,618 and $170,478, respectively. During 2023, $1,446,337 in forfeitures was used to reduce employer contributions, and $7,114 was used to pay administrative expenses.

Company Stock Funds

The Plan invests in common stock of the Company through its Company Stock Funds. The Company Stock Funds may also hold cash or other short-term securities, although these are expected to be a small percentage of the fund. Dividends received by the Company Stock Funds are reinvested in Company common stock.

The Plan limits the amount a participant can invest in the Company Stock Funds to encourage diversification of participants’ accounts. Contribution limits were set at a maximum of 10% of a participant’s contributions. In addition, a participant may not transfer amounts from other investment funds into the Company Stock Funds to the extent the transfer would result in more than 10% of the participant’s total account balance being invested in the Company Stock Funds.

2.    Summary of Significant Accounting Policies

Basis of Accounting

The financial statements of the Plan have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

SiteOne Savings and Investment Plan

Notes to Financial Statements (continued)

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Investment Valuation and Income Recognition

The Plan’s investments are reported at fair value. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). See Note 3 for discussion of fair value measurements.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded when received. Dividends are recorded on the ex-dividend date. Net appreciation/(depreciation) includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Notes Receivable from Participants

Notes receivable from participants are measured at their unpaid principal balance. Interest income is recorded when received. Related fees are recorded as administrative expenses and are expensed as they are incurred. No allowance for credit losses has been recorded as of December 31, 2023 or 2022. If a participant ceases to make loan repayments and the plan administrator deems the participant loan to be in default, the participant loan balance is reduced, and a benefit payment is recorded. There were $58,929 in deemed distributions recorded during the year ended December 31, 2023.

Payment of Benefits

Benefits are recorded when paid.

Expenses

Certain expenses of maintaining the Plan are paid directly by the Company and are excluded from these financial statements. The Company does not expect reimbursement from the Plan for these expenses. Participants are charged an asset-based service fee for administrative expenses of the Plan related to recordkeeping, accounting, and investment advisory services. Participants also pay certain administrative fees for participant-initiated transactions. Investment related expenses are included in net appreciation/(depreciation) of fair value of investments.

3.    Fair Value Measurements

The framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under the Financial Accounting Standards Board Accounting Standards Codification 820, Fair Value Measurement (“FASB ASC 820”) are described as follows:

Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets.

SiteOne Savings and Investment Plan

Notes to Financial Statements (continued)

Level 2: Inputs to the valuation methodology include:

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes to the methodologies used at December 31, 2023 and 2022.

Cash, Interest Bearing: Valued at amortized cost plus accrued interest, which approximates fair value.

Mutual Funds, Money Market Fund, Self-Directed Brokerage Accounts, and Company Common Stock: Valued at the daily closing price as reported by the respective fund. Mutual funds held by the Plan are open-end mutual funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily net asset value (“NAV”) and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded.

Collective Investment Trust Fund: The Fidelity Managed Income Portfolio (“MIP”) is a collective investment trust fund that seeks to preserve principal by maintaining a stable NAV. The funds trade daily using NAV as a practical expedient. The fund has redemption restrictions that limit the timing of withdrawals. Participant directed withdrawals may be made on any business day, provided that the exchange is not directed into a competing fund. Transferred amounts must hold a non-competing investment option for 90 days before funds may be transferred to a competing fund. In addition, redemptions of the fund directed by the Company must be preceded by 12 months written notice to Fidelity.

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

4.    Investment that Trades at NAV as a Practical Expedient

The following tables set forth additional disclosures of the investments whose fair value is estimated using NAV per share or its equivalent as a practical expedient as of December 31, 2023 and 2022 for the Plan:

5.  Plan Termination

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants would become fully vested in their Company contributions. The Plan’s assets would be distributable to the participants in accordance with the respective values of their accounts.

6.    Income Tax Status

The Company has adopted a pre-approved Plan document, which has received a determination letter dated June 30, 2020, that the Plan document is designed in accordance with applicable sections of the Internal Revenue Code (“IRC”). The plan administrator and the Plan’s management believe that the Plan, as restated, is designed and is currently being operated in compliance with the applicable requirements of the IRC and therefore believe the Plan is qualified and the related trust is tax-exempt.

7.    Risks and Uncertainties

The Plan invests in various investments. Investments are exposed to various risks such as interest rate, market, and credit volatility. Market risks include U.S. and global events that could impact the value of Plan investments. Such events may include public health emergencies such as a pandemic, as well as international conflicts, cybersecurity attacks (including increasingly sophisticated attack leveraging artificial intelligence capabilities), supply chain disruptions, global monetary policy decisions, inflation and elevated interest rates for prolonged periods, significant economic influences, and other adverse credit and market events and conditions. Due to the level of risk associated with certain investments, it is at least reasonably possible that changes in the values of investments will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

8.    Related Party Transactions and Party-in-Interest Transactions

The Plan held 31,739 and 30,101 shares of Company common stock valued at $5,159,539 and $3,533,109 at December 31, 2023 and 2022, respectively. There were no dividends declared on the Company common stock during 2023.

Plan investments include shares of mutual funds, a money market fund, self-directed brokerage accounts, and a collective investment trust fund managed by Fidelity. Fidelity is a service provider for the Plan; therefore, transactions in these investments qualify as party-in-interest transactions. Fees incurred by the Plan for investment management services are included in net appreciation of fair value of investments, as they are paid through revenue sharing rather than a direct payment.
