Exhibit 99.8

ADI GLOBAL DISTRIBUTION INC.

PERFORMANCE STOCK UNIT ASSUMPTION NOTICE

2026 Stock Incentive Plan

of ADI Global Distribution Inc. and its Affiliates

2026 [rTSR] [ROIC] PSUs

Dear [____]:

As you know, on August 3, 2026 (the “Spin Date”), the spin-off (the “Spin-Off”) of ADI Global Distribution Inc. (“ADI”) from Resideo Technologies, Inc. (“Resideo”) was completed. On the Spin Date you held outstanding and unvested performance stock units (“PSUs”) payable in shares of Resideo common stock (“Resideo Stock”) that were previously granted to you under the Amended and Restated 2018 Stock Incentive Plan of Resideo Technologies, Inc. and its Affiliates (the “Resideo Stock Incentive Plan”) and pursuant to performance stock unit agreement(s) and any amendments thereto (collectively, the “Resideo PSU Agreement”).

Pursuant to the Employee Matters Agreement entered into between Resideo and ADI in connection with the Spin-Off (the “EMA”), on the Spin Date, ADI assumed all obligations of Resideo under your PSUs that were outstanding and unvested as of the Spin Date, and such unvested PSUs automatically converted to performance stock units (“Converted PSUs”) payable in shares of ADI common stock (“ADI Stock”) under the 2026 Stock Incentive Plan of ADI Global Distribution Inc. and its Affiliates (the “ADI Stock Incentive Plan”). Pursuant to the EMA, 100% of the target number of shares subject to your 2026 PSUs have been converted into Converted PSUs subject to time- and performance-based vesting criteria as determined by the Compensation and Human Capital Management Committee of the Board of Directors of Resideo.

This Performance Stock Unit Assumption Notice (the “Assumption Notice”) evidences the terms of ADI’s assumption of your Converted PSUs pursuant to the EMA, including the necessary adjustments for assumption of your PSUs that are required by the Spin-Off. Following the Spin Date, your Converted PSUs will be governed by the ADI Stock Incentive Plan but shall generally remain subject to the terms and conditions of your Resideo PSU Agreement.

The table below summarizes your PSUs before and after the Spin-Off, and the material terms applicable to your Converted PSUs:

All of the terms and conditions of your Resideo PSU Agreement as in effect immediately prior to the Spin Date shall continue in full force and effect, except as expressly modified by this Assumption Notice, the EMA, certain administrative changes, or otherwise in connection with the Spin-Off.

Any capitalized term that is used but not defined in this Assumption Notice or your Resideo PSU Agreement will have the meaning assigned to it in the Resideo Stock Incentive Plan; provided, that, unless the context requires otherwise, any references in the Resideo Stock Incentive Plan and your Resideo PSU Agreement to: (i) the “Company” means ADI, (ii) “Stock,” “Common Stock” or “Shares” means shares of ADI Stock, (iii) “Board of Directors” or “Board” means the Board of Directors of ADI, and (iv) the “Committee” or the “Compensation and Human Capital Management Committee” means the Compensation Committee of the Board of Directors of ADI or such other committee designated by the Board of Directors of ADI in accordance with the ADI Stock Incentive Plan.

Please follow the instructions below to acknowledge and accept this Assumption Notice and your Converted PSUs. If you would like any further information or have any questions regarding this Assumption Notice or your Converted PSUs, please contact HRAdvisor via email at HRAdvisor@adiglobal.com.
