Item 1.01 Entry into a Material Definitive Agreement.

On August 25, 2026, subsidiaries of Pool Corporation (the “Company”) 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 amends the Company’s 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 million committed and $100 million uncommitted) in the months of March through September and $300.0 million ($200 million committed and $100 million uncommitted) during the remaining months of the year. Amounts outstanding under the Amended Receivables Purchase Agreement bear interest at one-month Term SOFR plus an applicable margin of 0.75% or 0.85% for committed and uncommitted tranches, respectively.

In the ordinary course of business, the Company and its affiliates have engaged, and may in the future engage, certain parties to the Amended Receivables Purchase Agreement or their affiliates to provide commercial banking, investment banking and other services for which the Company and its affiliates have paid or will pay customary fees or commissions.

The foregoing description of the Amended Receivables Purchase Agreement is not intended to be complete and is qualified in its entirety by reference to the full text of the Amended Receivables Purchase Agreement, which is filed as Exhibit 10.1 to this Form 8-K and is incorporated herein by reference. The Amended Receivables Purchase Agreement is included as an exhibit to this Form 8-K to provide information regarding the terms of the Amended Receivables Purchase Agreement and is not intended to provide any other factual or disclosure information about the Company or the other parties thereto. The Amended Receivables Purchase Agreement contains representations, warranties and covenants that the parties thereto made to each other as of specific dates. These representations and warranties may apply standards of materiality in a way that is different from what may be viewed as material to you or other investors and may have been used for the purpose of allocating risk between the parties rather than establishing matters of fact.
