TENET HEALTHCARE CORP

In March 2024, subsidiaries of our wholly owned USPI Holding Company, Inc. subsidiary, acquired controlling interests in 41 ambulatory surgery centers (together, the “March 2024 ASCs”). We have excluded the March 2024 ASCs’ operations from our assessment of and conclusion on the effectiveness of our internal control over financial reporting. The March 2024 ASCs represent 3% of our consolidated total assets and 1% of our consolidated net operating revenues as of and for the year ended December 31, 2024. SEC rules require us to include acquired entities in our assessment of the effectiveness of internal control over financial reporting no later than the annual management report following the first anniversary of the acquisition. We will complete the evaluation and integration of the March 2024 ASCs’ operations within the required timeframe and report management’s assessment of our internal control over financial reporting in our first annual report in which such assessment is required. Other than this transaction, there were no changes in our internal control over financial reporting during the quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined by Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act as of the end of the period covered by this report. The evaluation was performed under the supervision and with the participation of management, including our chief executive officer and chief financial officer. Based upon that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are effective as of December 31, 2024 to ensure that material information is recorded, processed, summarized and reported by management on a timely basis in order to comply with our disclosure obligations under the Exchange Act and the SEC rules thereunder.

Management’s report on internal control over financial reporting is set forth on page 70 and is incorporated herein by reference. The independent registered public accounting firm that audited the financial statements included in this report has issued an attestation report on our internal control over financial reporting as set forth on page 71 herein.
