PATRICK INDUSTRIES INC

Disclosure Controls and Procedures

The Company maintains “disclosure controls and procedures”, as such term is defined under Securities Exchange Act Rule 13a-15(e) or 15d-15(e), that are designed to ensure that information required to be disclosed in our Securities Exchange Act of 1934, as amended (the “Exchange Act”) reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, the Company’s management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and the Company’s management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Under the supervision and with the participation of our senior management, including our Chief Executive Officer and Chief Financial Officer, the Company conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report (the “Evaluation Date”). Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded as of the Evaluation Date that our disclosure controls and procedures were effective such that the information relating to the Company, including consolidated subsidiaries, required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to Company’s management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control system was designed to provide reasonable assurance regarding the fair and reliable preparation and presentation of our published financial statements. We continually evaluate our system of internal control over financial reporting to determine if changes are appropriate based upon changes in our operations or the business environment in which we operate.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an assessment of the effectiveness of our internal control over financial reporting based on the framework in the 2013 Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). This assessment included a review of the documentation of controls, an assessment of the design effectiveness of controls, testing of the operating effectiveness of controls, and a conclusion on this evaluation. As permitted under SEC guidance, management’s assessment of and conclusion regarding the design and effectiveness of internal control over financial reporting excluded the internal control over financial reporting of the operations of businesses acquired in 2025, which are described in Note 3 "Acquisitions" of the Notes to Consolidated Financial Statements included elsewhere in this Form 10-K. Businesses acquired in 2025 represented approximately 1% of consolidated net sales for the year ended December 31, 2025 and approximately 2% of consolidated total assets as of December 31, 2025. Based on our assessment, we have concluded that our internal control over financial reporting was effective as of December 31, 2025.

The Company’s independent registered public accounting firm, Deloitte & Touche LLP, audited our internal control over financial reporting as of December 31, 2025, as stated in their report in the section entitled “Report of Independent Registered Public Accounting Firm” included elsewhere in this Form 10-K, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025.

Changes in internal control over financial reporting

There have been no changes in our internal control over financial reporting that occurred during the fourth quarter ended December 31, 2025 or subsequent to the date the Company completed its evaluation, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
