| Business Combination, Pro Forma Information [Table Text Block] | The following table presents the financial results in thousands for AMPAC from the date of acquisition through June 30, 2024 and for the second quarter ended June 30, 2024 (in thousands).
The following table presents our estimated unaudited pro forma consolidated results for the second quarter and six months ended June 30, 2024, 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 NewMarket. Unaudited pro forma information for the second quarter and six months ended June 30, 2024 includes 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 second quarter and six months ended June 30, 2024, but for the presentation below, these costs are excluded from 2024 unaudited pro forma income before income taxes since on a pro forma basis, they would have been incurred during 2023.
