Refer to Note 3, "Assets and Liabilities Held for Sale and Discontinued Operations" of the notes to the consolidated financial statements for further information.

At April 1, 2025, the Company reallocated goodwill of reporting units impacted by the change in reportable segments described in Note 16, "Segment Information," of the notes to the consolidated financial statements and assessed goodwill for impairment. The Company determined that the estimated fair value of each reporting unit exceeded its corresponding carrying amount including recorded goodwill, and as such, no impairment existed at April 1, 2025.

During the third quarter of fiscal 2025, the Company signed a definitive agreement to sell its ADT Mexico residential security business, resulting in a triggering event for the impacted reporting unit. The Company performed a quantitative goodwill impairment test of the reporting unit with $174 million of remaining goodwill, and its fair value was slightly in excess of its carrying value. However, for this reporting unit, a 50 basis point increase in the discount rate, or a 100 basis point decrease in the revenue growth rates, would cause the fair value to be less than the carrying value. While no impairment was recorded, it is possible that future changes in circumstances could result in a non-cash impairment charge. The Company used a discounted cash flow model to estimate the fair value of the reporting unit. The primary assumptions used in the model were management's internal projections of future cash flows, the weighted-average cost of capital and the long-term growth rate, which are classified as Level 3 inputs within the fair value hierarchy as defined in ASC 820, "Fair Value Measurement." This reporting unit was previously disclosed as being at risk of impairment in the Company’s Annual Report on Form 10-K for the year-ended September 30, 2024.
