The unaudited pro forma condensed combined financial information were prepared using the acquisition method of accounting in accordance with Accounting Standards Codification 805, Business Combinations (“ASC 805”) with the Company considered the accounting acquirer.

Any excess of purchase price over the fair value of the net assets acquired is recorded as goodwill.

The unaudited pro forma adjustments, reflecting the consummation of the Durango Acquisition on June 24, 2024, are based on certain currently available information to the Company and may be revised as additional information becomes available and is evaluated by the Company. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments, and it is possible that the differences may be material.

(b) Reflects the elimination of Durango’s historical depreciation and amortization expense and the recognition of depreciation and amortization expense based on the estimated fair values and estimated remaining useful lives of the acquired property, plant, and equipment and intangible assets on the Closing Date.
