POOL CORP

Note 1 – Summary of Significant Accounting Policies

Pool Corporation (the Company, which may also be referred to aswe, us orour) prepared the unaudited interim Consolidated Financial Statements following U.S. generally accepted accounting principles (GAAP) and the requirements of the Securities and Exchange Commission (SEC) for interim financial information. As permitted under those rules, we have condensed or omitted certain footnotes and other financial information required for complete financial statements.

The interim Consolidated Financial Statements include all normal and recurring adjustments that are necessary for a fair presentation of our financial position and operating results. All significant intercompany accounts and intercompany transactions have been eliminated.

A description of our significant accounting policies is included in our 2025 Annual Report on Form 10-K. You should read the interim Consolidated Financial Statements in conjunction with the Consolidated Financial Statements and accompanying notes in our 2025 Annual Report on Form 10-K. The results for our three and nine months ended September 30, 2026 are not necessarily indicative of the expected results for our fiscal year ending December 31, 2026.

We reduce federal and state income taxes payable by the tax benefits associated with the exercise of nonqualified stock options and the lapse of restrictions on restricted stock awards and increase them for tax deficiencies. To the extent realized tax deductions exceed the amount of previously recognized deferred tax benefits related to share-based compensation, we record an excess tax benefit. To the extent realized tax deductions are less than the amount of previously recognized deferred tax benefits related to share-based compensation, we record an excess tax expense. We record all excess tax benefits or deficiencies as a component of income tax benefit or expense on the Consolidated Statements of Income in the period in which stock options are exercised or restrictions on stock awards lapse. For the nine months ended September 30, 2026, we recorded an excess tax benefit of$0.7 million compared to an excess tax benefit of$4.2 million in the nine months ended September 30, 2025.

Retained Earnings

We account for the retirement of repurchased shares as a decrease to Retained earnings on the Consolidated Balance Sheets. As of September 30, 2026, Retained earnings reflects cumulative net income, the cumulative impact of adjustments for changes in accounting pronouncements, share retirements since the inception of our share repurchase programs of$3.3 billion and cumulative dividends of$1.6 billion.

Accumulated Other Comprehensive Loss

The table below presents the components of our Accumulated other comprehensive loss balance (in thousands):

Recent Accounting Pronouncements Pending Adoption

The following table summarizes recent accounting pronouncements that we plan to adopt in future periods:

Note 2 – Earnings Per Share

We calculate basic and diluted earnings per share using the two-class method. Earnings per share under the two-class method is calculated using net income attributable to common stockholders, which is net income reduced by the earnings allocated to participating securities. Our participating securities include share-based awards that contain a non-forfeitable right to receive dividends and are considered to participate in undistributed earnings with common shareholders. Participating securities excluded from weighted average common shares outstanding were 216,000 forthe three months ended September 30, 2026 and 184,000 for thethree months ended September 30, 2025, and 206,000 for thenine months ended September 30, 2026 and 184,000 for the nine months ended September 30, 2025.

The table below presents the computation of earnings per share, including the reconciliation of basic and diluted weighted average shares outstanding (in thousands, except per share data):

(1)

Since these options have exercise prices that are higher than the average market prices of our common stock, including them in the calculation would have an anti-dilutive effect on earnings per share.

Note 3 – Acquisitions

In October 2025, we acquired the distribution assets of Vegas Stone Brokers, a stone and hardscapes supplier, addingone location in Nevada.

In August 2025, we acquired the distribution assets of Great Plains Supply Pool and Spa Products, a wholesale distributor of swimming pool products and supplies, addingone location in Kansas andone location in Texas.

We have completed our accounting for these acquisitions, subject to adjustments for standard holdback provisions per the terms of the purchase agreements, which are not material.

Note 4 – Fair Value Measurements and Interest Rate Swaps

Recurring Fair Value Measurements

Our assets and liabilities that are measured at fair value on a recurring basis include the unrealized gains or losses on our interest rate swap contracts and our deferred compensation plan asset and liability. The three levels of the fair value hierarchy under the accounting guidance are described below:

•

quoted prices for similar assets or liabilities in active markets;

•

quoted prices for identical or similar assets or liabilities in inactive markets;

•

inputs other than quoted prices that are observable for the asset or liability; or

•

inputs that are derived principally from or corroborated by observable market data by correlation or other means.

The table below presents our assets and liabilities measured and recorded at fair value on a recurring basis (in thousands):

Interest Rate Swaps

We utilize interest rate swap contracts to reduce our exposure to fluctuations in variable interest rates for future interest payments on a portion of our variable rate borrowings.

We use significant other observable market data or assumptions (Level 2 inputs) in determining the fair value of our interest rate swap contracts that we believe market participants would use in pricing similar assets or liabilities, including assumptions about counterparty risk. Our fair value estimates reflect an income approach based on the terms of the interest rate swap contracts and inputs corroborated by observable market data including interest rate curves.

We recognize any differences between the variable interest rate in effect and the fixed interest rates per our swap contracts as an adjustment to interest expense over the life of the swaps. To the extent our derivatives are effective in offsetting the variability of the hedged cash flows, we record the changes in the estimated fair value of our interest rate swap contracts to Accumulated other comprehensive loss on the Consolidated Balance Sheets.

Our interest rate swaps in effect during the first nine months of 2026 were previously forward-starting and converted the variable interest rate to a fixed interest rate on a portion of our variable rate borrowings. Interest expense related to the notional amounts under our swap contracts was based on the fixed rates plus the applicable margin on our variable rate borrowings. Changes in the estimated fair value of these interest rate swap contracts were recorded to Accumulated other comprehensive loss on the Consolidated Balance Sheets.

We currently have two interest rate swap contracts in place. The following table provides additional details related to these swap contracts:

For the interest rate swap contracts in effect at September 30, 2026, a portion of the change in the estimated fair value between periods relates to future interest expense. Recognition of the change in fair value between periods attributable to accrued interest is reclassified from Accumulated other comprehensive loss on the Consolidated Balance Sheets to Interest and other non-operating expenses, net on the Consolidated Statements of Income. These amounts were not material in the three and nine months ended September 30, 2026 or September 30, 2025.

Failure of our swap counterparties would result in the loss of any potential benefit to us under our swap agreements. In this case, we would still be obligated to pay the variable interest payments underlying our debt agreements. Additionally, failure of our swap counterparties would not eliminate our obligation to continue to make payments under our existing swap agreements if we continue to be in a net pay position.

Our interest rate swap contracts are subject to master netting arrangements. According to our accounting policy, we do not offset the fair values of assets with the fair values of liabilities related to these contracts.

Other

Our deferred compensation plan asset represents investments in securities (primarily mutual funds) traded in an active market (Level 1 inputs) held for the benefit of certain employees as part of our deferred compensation plan. We record an equal and offsetting deferred compensation plan liability, which represents our obligation to participating employees. We have reflected changes in the fair value of the plan asset and liability in Selling and administrative expenses on the Consolidated Statements of Income.

The carrying values of cash and cash equivalents, receivables, accounts payable and accrued expenses approximate fair value due to the short maturity of those instruments. The carrying value of long-term debt approximates fair value. Our determination of the estimated fair value reflects a discounted cash flow model using our estimates, including assumptions related to borrowing rates (Level 3 inputs).

Note 5 – Debt

The table below presents the components of our debt (in thousands):

On August 25, 2026, our subsidiaries entered into Amendment No. 14 to the Receivables Purchase Agreement by and among Superior Commerce LLC, as Seller, SCP Distributors LLC, as the Servicer, the purchasers from time to time party thereto, and Wells Fargo Bank, National Association, as Administrative Agent (as amended, the Amended Receivables Purchase Agreement). The Amended Receivables Purchase Agreement amended our receivable securitization facility principally to extend the facility termination date to August 25, 2028 and increase the maximum facility limit to$400.0 million in the months of March through September. As amended, the facility has a maximum facility limit of$400.0 million ($300.0 million committed and$100.0 million uncommitted) in the months of March through September and$300.0 million ($200.0 million committed and$100.0 million uncommitted) during the remaining months of the year. Amounts outstanding under the Amended Receivables Purchase Agreement bear interest at the one-month term secured overnight financing rate (Term SOFR) plus an applicable margin of 0.75% or 0.85% for committed and uncommitted tranches, respectively.

Our receivable securitization facility (the Receivables Facility) provides for the sale of our receivables to a wholly-owned subsidiary (the Securitization Subsidiary). The Securitization Subsidiary transfers variable undivided percentage interests in the receivables and related rights to certain third-party financial institutions in exchange for cash proceeds, limited to the applicable funding capacities.

We account for the sale of the receivable interests as a secured borrowing on our Consolidated Balance Sheets. The receivables subject to the agreement collateralize the cash proceeds received from the third-party financial institutions. We classify the entire outstanding balance as Long-term debt, net on our Consolidated Balance Sheets as we intend and have the ability to refinance the obligations on a long-term basis. We present the receivables that collateralize the cash proceeds separately as Receivables pledged under receivables facility on our Consolidated Balance Sheets.

Note 6 – Segment Information

Since all of our sales centers have similar operations and share similar economic characteristics, we aggregate our sales centers into a single reportable segment andone reportable revenue stream. These similarities include (i) the nature of our products and services, (ii) the types of customers to whom we sell and (iii) the distribution methods we use. Our chief operating decision maker (CODM) is our president and chief executive officer. The accounting policies for our segment are the same as those described in Note 1 of our “Notes to Consolidated Financial Statements,” included in Part II, Item 8 in our 2025 Annual Report on Form 10-K and in Note 1 above.
