Dusk Acquisition Corporation

On November 4, 2025, we acquired 100% of the equity interests of Dusk Acquisition Corporation and its wholly owned subsidiaries, Motors & Armatures Parts, LLC and HVAC South, LLC (collectively, “MARS Parts”), based in Hauppauge, New York, for an aggregate purchase price of $667.5 million (including $6.0 million cash acquired), comprised of cash consideration of $650.0 million, estimated cash on balance sheet at closing of $4.1 million, and contingent considerations initially measured at $13.4 million based on MARS Parts meeting defined financial targets over a period of one year. The cash consideration was funded with a combination of the TLA (as defined in Note 7) and borrowings under our existing Revolving Credit Facility (as defined in Note 7). As of the acquisition date, the estimated fair value of the contingent consideration was classified as a current liability of $13.4 million, which was determined using an option pricing model simulation that determines an average projected payment value across numerous iterations. MARS Parts is one of the largest providers of HVAC/R parts and supplies in North America, and a leading provider of motors and capacitors. With a product mix more heavily focused on repair versus replacement, we expect MARS Parts will strategically complement our current HVAC/R end market, which traditionally has been more focused on new unit installations and replacements.

The MARS Parts acquisition was accounted for as a business combination under FASB Accounting Standards Codification Topic 805, Business Combinations ("Topic 805"). Pursuant to Topic 805, the Company allocated the MARS Parts purchase price to tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date, November 4, 2025. The excess of the purchase price over those fair values was recorded to goodwill. The Company's evaluation of the facts and circumstances available as of November 4, 2025, to assign fair values to assets acquired and liabilities assumed, including income tax related amounts, is ongoing. The primary areas of preliminary purchase accounting price allocation subject to changes relate to the assumptions used in the valuation model, the valuation of working capitals and property, plant and equipment, and deferred tax balances. We expect to finalize the purchase price allocation as soon as practicable, but no later than one year from the acquisition date. The following table summarizes the Company's best initial estimate of the aggregate fair value of the assets acquired and liabilities assumed at the date of acquisition (in thousands).

Goodwill of $265.0 million represents the excess of the purchase price over the fair value of the underlying tangible and intangible assets acquired and liabilities assumed. The acquisition goodwill represents the value expected to be obtained from expanding the Company’s product offerings more broadly across the HVAC/R end market. The goodwill recorded as part of this acquisition is included in the Contractor Solutions segment. The Company has assumed the seller's tax basis in goodwill ($16.7 million) and intangible assets ($143.9 million), which will continue to be amortized over the remaining tax life of 14 years.

MARS Parts generated net revenue of $16.9 million and net loss before income taxes of $3.8 million for the period from the acquisition date to December 31, 2025, primarily driven by the expenses incurred to rapidly integrate the business post acquisition. MARS Parts activity is currently included in our Contractor Solutions segment. During the three and nine months ended December 31, 2025, the Company incurred $1.9 million and $3.4 million, respectively, of transaction expenses in connection with the MARS Parts acquisition. Transaction expenses are included in selling, general and administrative expenses in the Consolidated Statement of Operations under the Contractor Solutions and Other segments.

Aspen Manufacturing, LLC

On May 1, 2025, we acquired 100% of the equity interests of Aspen Manufacturing, LLC (“Aspen Manufacturing”), based in Humble, Texas, for an aggregate purchase price of $327.6 million (including $2.3 million cash acquired), comprised of cash consideration of $313.5 million and working capital adjustments of $14.1 million. The cash consideration was funded with cash on hand and borrowings under our existing Revolving Credit Facility (as defined in Note 7). Aspen Manufacturing is one of the largest independent evaporator coil and air handler manufacturers for the HVAC/R industry and is recognized as a leader in product quality and indoor comfort. Aspen Manufacturing’s current product suite includes a vast range of high-quality residential and light commercial evaporator coils, blowers, and air handling units for single-family, multi-family, and manufactured homes.

The Aspen Manufacturing acquisition was accounted for as a business combination under Topic 805. Pursuant to Topic 805, the Company allocated the Aspen Manufacturing purchase price to tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date, May 1, 2025. The excess of the purchase price over those fair values was recorded to goodwill. The Company's evaluation of the facts and circumstances available as of May 1, 2025, to assign fair values to assets acquired and liabilities assumed, including income tax related amounts, is ongoing. The primary areas of preliminary purchase accounting price allocation subject to changes relate to the valuation of working capitals, income tax contingency and related indemnification asset and value of property, plant and equipment. We expect to finalize the purchase price allocation as soon as practicable, but no later than one year from the acquisition date. The following table summarizes the Company's best initial estimate of the aggregate fair value of the assets acquired and liabilities assumed at the date of acquisition (in thousands).
