Evaluation of Disclosure Controls and Procedures

As of September 30, 2026, our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), together with management, conducted an evaluation of the effectiveness of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based on that evaluation, the CEO and CFO concluded that these disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2026.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the three months ended September 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Notwithstanding the above, prior to November 1, 2025, we relied on certain material processes and internal controls over financial reporting performed by DuPont. In connection with our Separation, we entered into Transition Services Agreements, pursuant to which DuPont will continue to provide certain information technology, administrative and other services on a transitional basis. During the quarter ended September 30, 2026, we exited certain of the services being provided under the Transition Services Agreements. Management remains responsible for the effectiveness of disclosure controls and procedures and evaluated the information and services provided under these arrangements through oversight and monitoring controls.
