Dear Marco:

I am pleased to extend this offer to become Senior Vice President, Chief Merchandising Officer (“CMO”) of ADI Global Distribution Inc. (“ADI” or the “Company”), effective as of, and contingent upon, the anticipated spin-off of ADI Global Distribution Inc. from Resideo Technologies, Inc. (the “Spin-off”).¹ The date of the Spin-off and your consequent appointment as CMO is hereinafter referred to as the “Effective Date”.

For the sake of clarity, should the Spin-off not occur as anticipated, this offer automatically becomes null and void.

As of the Effective Date, your employment will be subject to the terms and conditions of this offer letter, and you will be entitled to the following compensation and benefits package.

COMPENSATION

Base Salary

As of the Effective Date, your annual base salary will remain $400,000. Base salary reviews occur annually, and any adjustments are generally made at the end of the first quarter of the calendar year, based on performance and other relevant factors. Any base salary adjustments will be subject to approval of the Compensation Committee of the ADI Board of Directors (the “Compensation Committee”).

Annual Incentive Compensation

As of the Effective Date, you will remain eligible for an annual bonus with a target of 70% of your annual cash base salary earnings. Incentive compensation awards are generally paid in the first quarter of the following year (e.g., in the first quarter of 2027 for the 2026 performance year), are governed by the terms of the applicable bonus plan, and are subject to approval by the Compensation Committee.

This offer is also contingent upon written approval by the ADI Board of Directors.

Annual Long-Term Incentive Awards

Beginning in 2027, you will be eligible for annual long-term incentive (“LTI”) awards which may consist of time-based restricted stock units (“RSUs”), options, performance-based restricted stock units, or some combination thereof, as determined by the Compensation Committee, in its discretion. The terms of all LTI awards will be governed by the applicable stock plan and relevant award agreements.

OTHER EXECUTIVE BENEFITS

Excess Liability Insurance: Resideo will pay the annual premium for an Excess Liability Insurance policy that provides $5,000,000 of personal liability umbrella coverage per occurrence.

Executive Physical: You will be eligible for an annual executive physical and related health concierge program, with such program to be determined by the Compensation Committee.

Officer Severance: You will be covered under the ADI Global Distribution Inc. Severance Plan for Designated Officers (the “Officer Severance Plan”) in effect at the time of your separation. In order to receive severance benefits, you will be required to execute a separation agreement including a release of claims in favor of ADI and its affiliates, and you may be required to agree to certain non-disclosure and restrictive covenants.
