2. Acquisition of Business

On January 16, 2024, we completed the acquisition of all issued and outstanding ownership units of AMPAC Intermediate Holdings, LLC, the ultimate parent company of American Pacific Corporation (AMPAC), for approximately $700 million. Based in Cedar City, Utah, AMPAC has one operating facility from which it manufactures and sells critical specialty materials primarily used in solid rocket motors for space launch and military defense applications. AMPAC is qualified on many NASA and Department of Defense programs and has been serving space launch and national defense programs for more than 60 years. The acquisition of AMPAC expands our presence in mission-critical, resilient sectors. It was funded by cash on hand and borrowings under our then existing revolving credit facility. The purchase consideration is subject to a customary post-closing adjustment for working capital, which is expected to be finalized during the second quarter of 2024.

The preliminary fair values of the assets acquired and the liabilities assumed in the AMPAC acquisition are as follows (in millions):

Identified intangible assets acquired consisted of the following (in millions):

As part of the acquisition, we recorded $258 million of goodwill. The goodwill recognized is attributable to increased access to mission-critical, resilient sectors with a role in global safety, security, and space exploration, as well as the value of the skilled assembled workforce of AMPAC. All of the goodwill recognized is part of the specialty materials segment, andnone of the goodwill is deductible for income tax purposes.

The allocation of the purchase price of AMPAC to the tangible and intangible assets acquired and liabilities assumed was developed using preliminary estimates of fair value and based on information currently available. We are continuing to finalize the valuation of certain assets and liabilities and expect to complete our valuations within one year of the date of acquisition. Acquisition-related charges of $1 million consisted primarily of legal and professional fees and are included in selling, general, and administrative expenses in our Consolidated Statements of Income.

We are accounting for this acquisition using the acquisition method of accounting for business combinations under the provisions of Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 805, Business Combinations (ASC 805) and have included the results of operations of the acquired business in our Consolidated Statement of Income from the date of acquisition, as well as in the specialty materials segment in Note 4. These results include a charge related to the sale of finished goods inventory acquired, which was recorded at fair market value on the acquisition date and sold to customers from the date of acquisition through March 31, 2024. The following table presents the financial results for AMPAC from the date of acquisition through March 31, 2024.

The following table presents our estimated unaudited pro forma consolidated results for the three months ended March 31, 2024 and March 31, 2023, assuming the acquisition of AMPAC had occurred on January 1, 2023. The unaudited pro forma information is presented for informational purposes only and is not indicative of the results of operations that would have been realized if the acquisition had been completed at the beginning of 2023, nor is it indicative of expected results for any future period. In addition, no effect is given to any future synergistic benefits that could result from the integration of AMPAC into the NewMarket companies.

Unaudited pro forma information for the three months ended March 31, 2024 and March 31, 2023 include adjustments to depreciation and amortization based upon the fair value allocation of the purchase price to AMPAC's tangible and intangible assets acquired and liabilities assumed as though the acquisition had occurred on January 1, 2023, as well as adjustments for debt-related costs and management fees. The acquisition-related costs and the charge related to the fair value adjustment to acquisition-date inventory were recognized in actual results during the three months ended March 31, 2024, but for the presentation below, these costs are excluded from 2024 unaudited pro forma income before income taxes and are instead reflected in 2023 pro forma income before income taxes as though they were incurred during the three months ended March 31, 2023.
