Honeywell Aerospace Inc.

Aerospace’s management, including the Chief Executive Officer (CEO) and Chief Financial Officer (CFO), conducted an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based upon that evaluation, our CEO and CFO concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, such disclosure controls and procedures were effective to ensure information required to be disclosed in the reports that Aerospace files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and that it is accumulated and communicated to our management, including our CEO, our CFO, and our Controller, as appropriate, to allow timely decisions regarding required disclosure. There were no changes that materially affected, or are reasonably likely to materially affect, Aerospace’s internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q.

Prior to June 29, 2026, we relied on certain material processes and internal controls over financial reporting performed by Honeywell. As a result of the Spin-off from Honeywell on June 29, 2026, we are in the process of reviewing, revising, and adopting policies and controls, as needed, to meet all regulatory requirements applicable to us as an independent, publicly traded company. In addition, in connection with the Spin-off, we entered into a Transition Services Agreement with Honeywell, pursuant to which Honeywell will continue to provide certain information technology, administrative, and other services on a transitional basis.
