Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

As previously disclosed on a Current Report on Form 8-K filed by Pool Corporation (the “Company”) on May 4, 2026 (the “Original Form 8-K”), the Company and Peter D. Arvan mutually agreed that Mr. Arvan will cease to serve as President and Chief Executive Officer, effective May 4, 2026. Accordingly, the Company and Mr. Arvan entered into a separation agreement and general release (the “Separation Agreement”). The Company is filing this Amendment No. 1 (the “Amendment”) to the Original Form 8-K to provide information regarding the Separation Agreement, which was not available at the time of filing of the Original Form 8-K.

As a result of Mr. Arvan’s resignation, under the Separation Agreement, he will receive his base salary for a period of 54 weeks after termination. In addition, Mr. Arvan is entitled to reimbursement of health insurance premiums for twelve months and will be eligible to continue vesting up to 55,156 shares of performance-based restricted stock awards subject to achievement of the applicable performance goals and up to 21,870 shares of restricted stock awards, in both cases provided he continues to comply with the non-competition requirements and the terms of the Separation Agreement. Receipt of these severance benefits is conditioned upon Mr. Arvan’s execution of a general release of claims, allowing such release to become effective and continued compliance with any applicable post-termination obligations as set forth in the Separation Agreement.

The Separation Agreement includes customary waiver and release provisions in favor of the Company, as well as non-competition, confidentiality, and non-disparagement provisions. In addition, certain payments and benefits due to Mr. Arvan under the Separation Agreement are subject to recovery by the Company in accordance with the Company’s compensation Clawback Policy and also upon the occurrence of certain specified events. The foregoing description of the Separation Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the agreement, a copy of which is filed as Exhibit 10.1 hereto and incorporated herein by reference.

Except as expressly set forth herein, this Amendment does not amend the Original Form 8-K in any way and does not modify or update any other disclosures contained in the Original Form 8-K. This Amendment supplements the Original 8-K and should be read in conjunction with the Original Form 8-K.
