(the “Company”) or (“ADS”), following the acquisition of National Diversified Sales (“NDS”) we realigned our reportable segments to align with the manner in which the Chief Operating Decision Maker (“CODM”) assesses performance and makes resource allocation decisions (the “Segment Realignment”). Our revised reportable segments consist of Stormwater and Wastewater (formerly referred to as the “Infiltrator” reportable segment). Further, we changed the measure used to evaluate segment profitability from adjusted gross profit to Adjusted EBITDA.\n\nSegment results for the historical periods presented in these consolidated financial statements have been recast to reflect these changes. The Segment Realignment had no impact on our previously reported consolidated net sales, income from operations, net income attributable to ADS or earnings per share.\n\nADS provided certain recast historical financial information for quarterly periods within fiscal 2026, 2025 and 2024 attached hereto as Exhibit 99.1 to this Current Report on Form 8-K.
