Organon & Co.

Our management, with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), 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) as of the period ending June 30, 2024. Based upon that evaluation, our CEO and our CFO concluded that, as of June 30, 2024, 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.

In 2023, we began an implementation of an enterprise resource planning (“ERP”) system to replace the existing core financial system. The ERP system is designed to accurately maintain our financial records used to report operating results. The implementation of the consolidated financial reporting module was completed during the 2023 fiscal year. The implementation of the general ledger modules occurred in phases and was completed during the second quarter of our 2024 fiscal year. The changes in process under the new ERP continue to be subject to our evaluation of the operating effectiveness of internal control over financial reporting.

Except for the implementation of an ERP system, there was no change in our internal control over financial reporting that occurred during the quarter ended June 30, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
