Re: Offer Letter
Dear Jim:
I am pleased to confirm our offer to you to become the President and Chief Executive Officer (“CEO”) of Honeywell Aerospace, Inc. (“New Aerospace”), a division of Honeywell International Inc. (“Honeywell”) that is expected to be spun off as an independent public company at some point in the third quarter of 2026 (the actual spin-off date, if applicable, is hereinafter referred to as the “Separation Date”). The role is effective as of the Separation Date and is based in Phoenix, Arizona.
In connection with your new role, you will be entitled to the following compensation and benefits package with New Aerospace:
COMPENSATION
Base Salary: As of the Separation Date, your annual base salary will be $1,400,000. After the Separation Date, your base salary shall adjusted by the compensation committee of New Aerospace’s Board of Directors from time to time. Adjustments are based on your performance and other relevant factors.
Annual Incentive Compensation Opportunity From New Aerospace: As of the Separation Date, your target incentive compensation opportunity with New Aerospace will be 175% of your annual cash base salary earnings during the year. For the calendar year that contains the Separation Date, you will be eligible for an incentive compensation award from New Aerospace for post-Separation Date earnings. New Aerospace incentive compensation awards are paid in the first quarter of the following year.
Pre-Separation Date Annual Incentive Compensation Opportunity: You will continue to be eligible to receive an incentive compensation award for your services with Honeywell up through the Separation Date. Such award shall be based on your pre-Separation Date cash base salary earnings and incentive plan target percentage with Honeywell for the pre-separation period and shall be payable in the first quarter of the following year. Honeywell retains the right to assign the related payment obligation to New Aerospace.
Annual Long-Term Incentive Awards From New Aerospace: After the Separation Date, you will be eligible to receive annual long-term incentive (“LTI”) awards from New Aerospace consisting of stock options, restricted stock units, performance stock units or cash awards, or

some combination thereof, as determined by New Aerospace in its sole discretion. The New Aerospace awards shall have an annual target grant date value equal to $13,000,000.1 The actual size and mix of your future New Aerospace LTI awards will be determined by the compensation committee of New Aerospace’s Board of Directors based on your performance and future career potential. The terms of the New Aerospace LTI awards will be governed by the terms of the applicable stock plan and the relevant award agreements.2
