Organon & Co.

Our management, with the participation of our Chief Executive Officer (“CEO”) (our principal executive officer) and Chief Financial Officer (“CFO”) (our principal financial officer), evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended (the “Exchange Act”)) as of the period ending June 30, 2025. Based upon that evaluation, our CEO and our CFO concluded that, as of June 30, 2025, the end of the period covered by this report, our disclosure controls and procedures were effective and provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our CEO and our CFO, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an evaluation of any changes in our internal control over financial reporting that may have occurred during our most recently completed fiscal quarter. Based on that evaluation, our CEO and CFO concluded that during the quarter ended June 30, 2025, there have been no changes in internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
