River Valley Pipe is included in the Stormwater reportable segment. The purchase price allocation for assets acquired and liabilities assumed is complete and there were no changes to the valuations of assets acquired and liabilities assumed disclosed in the Fiscal 2026 Form 10-K. Acquisition of NDS - On February 2, 2026, the Company completed the acquisition of the water management business of Norma Group SE, known as NDS. NDS expands the Company’s water management offering into complementary products through the addition of NDS’ residential water management, access box and irrigation solutions. The preliminary fair value of consideration transferred was approximately $972.5 million, which represented the purchase price of $984.9 million, net of cash acquired of $3.2 million and cash included in held for sale of $9.2 million. The preliminary purchase price excludes transaction costs. The acquisition was primarily funded from cash on hand. NDS is included in the Stormwater reportable segment. Summary of Consideration Transferred - The Company has applied the acquisition method of accounting in accordance with ASC 805, Business Combinations (“ASC 805”) and recognized assets acquired and liabilities assumed at their fair value as of the date of acquisition, with the excess purchase consideration recorded to goodwill. As of June 30, 2026, there has been no change to the preliminary purchase price allocation of identified assets acquired and liabilities assumed as disclosed in the Fiscal 2026 Form 10-K. The purchase price allocation for assets acquired and liabilities assumed is preliminary and will be finalized when valuations are complete and final assessments of the fair value of acquired assets and assumed liabilities are completed. As the Company finalizes the estimation of the fair value of the assets acquired and liabilities assumed, additional adjustments may be recorded during the measurement period (up to one year from the closing date). Pro Forma Financial Information - The unaudited pro forma information for the three months ended June 30, 2025 presented below includes the effects of the NDS acquisition as if it had been consummated as of April 1, 2024, with adjustments to give effect to pro forma events that are directly attributable to the acquisition of NDS. Adjustments include those related to the depreciation and amortization of acquired fixed and intangible assets, transaction costs, inventory step-up and the estimated tax impacts thereof. The unaudited pro forma information does not reflect any operating efficiency or potential cost savings that could result from the consolidation of NDS. Accordingly, the unaudited pro forma information is presented for informational purposes only and is not necessarily indicative of the actual results of the combined company if the acquisition had occurred at the beginning of the period presented, nor is it indicative of the future results of operations.
