The unaudited pro forma condensed combined balance sheet as of September 30, 2022 gives effect to the Merger and the Debt Financing as if those transactions had been completed on September 30, 2022 and combines the unaudited condensed consolidated balance sheet of Regal Rexnord as of September 30, 2022 with Altra’s unaudited condensed consolidated balance sheet as of September 30, 2022. The unaudited pro forma condensed combined statements of income for the year ended January 1, 2022 and the nine months ended September 30, 2022 give effect to the Merger, the Debt Financing and the merger with the Rexnord PMC business as if they had occurred on January 3, 2021, the first day of Regal Rexnord’s year ended January 1, 2022, and combine the historical results of Regal Rexnord, the Rexnord PMC business and Altra, as applicable. The unaudited pro forma condensed combined statement of income for the year ended January 1, 2022 combines the audited consolidated statement of income of Regal Rexnord for the year ended January 1, 2022, the unaudited condensed combined statement of operations of the Rexnord PMC business for the nine months ended September 30, 2021 and the audited consolidated statement of operations of Altra for the year ended December 31, 2021. The unaudited pro forma condensed combined statement of income for the nine months ended September 30, 2022 combines the unaudited consolidated statement of income of Regal Rexnord for the nine months ended September 30, 2022 with the unaudited consolidated statement of operations of Altra for the nine months ended September 30, 2022. Regal Rxxxxxx’s, Axxxx’s and the Rexnord PMC business’ historical financial statements were prepared in accordance with GAAP and are presented in U.S. dollars. As discussed in Note 2, certain reclassifications were made to align Regal Rxxxxxx’s, the Rexnord PMC business’, and Axxxx’s financial statement presentation. Regal Rexnord is currently in the process of evaluating Altra’s accounting policies. That review will be finalized upon completion of the Merger, or as more information becomes available. As a result of that review, differences could be identified between the accounting policies of the two companies that, when conformed, could have a material impact on the combined company’s financial information. With the information currently available, Regal Rexnord has determined that no significant adjustments are necessary to conform Axxxx’s financial statements to the accounting policies used by Regal Rexnord. As of January 2, 2022, Regal Rexnord changed the methodology for valuing certain inventories to the first-in, first-out (“FIFO”) cost method from the last-in, first-out (“LIFO”) cost method (the “LIFO to FIFO Change”). The Company believes that this change in accounting is preferable as it provides a better matching of costs and revenues, more closely resembles the physical flow of inventory, better reflects acquisition cost of inventory on the balance sheet, conforms the Company’s method of inventory valuation to a single method, results in improved comparability with industry peers and reduces the administrative burden of determining the LIFO valuation. The effects of the LIFO to FIFO Change have been reflected in the Company’s financial statements for the period ended September 30, 2022. The effects of the LIFO to FIFO Change have not been reflected in the Company’s financial statements and in the unaudited pro forma condensed combined statement of income for the year ended January 1, 2022. The unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting in accordance with ASC 805, with Regal Rexnord as the accounting acquirer, using the fair value concepts defined in ASC Topic 820, Fair Value Measurement, and based on the historical consolidated financial statements of Regal Rexnord and Altra. Under ASC 805, all assets acquired and liabilities assumed in a business combination are recognized and measured at their assumed acquisition date fair value, while transaction costs associated with the business combination are expensed as incurred. The excess of the Merger Consideration over the estimated fair value of assets acquired and liabilities assumed, if any, is allocated to goodwill. The allocation of the Merger Consideration depends upon certain estimates and assumptions, all of which are preliminary. The allocation of the Merger Consideration has been made for the purpose of developing the unaudited pro forma condensed combined financial information. The final determination of fair values of assets acquired and liabilities assumed relating to the Merger could differ materially from the preliminary allocation of the Merger Consideration. The final valuation will be based on the actual net tangible and intangible assets of Altra existing at the acquisition date. The allocation of the Merger Consideration set forth herein will be revised as additional information becomes available. Any such revisions or changes may be material. The unaudited pro forma condensed combined financial information does not reflect any anticipated synergies or dyssynergies, operating efficiencies or cost savings that may result from the Merger or any acquisition and integration costs that may be incurred. Regal Rexnord is not aware of any material transactions between Regal Rexnord, the Rexnord PMC business, and Altra during the periods presented. Accordingly, adjustments to eliminate transactions between Regal Rexnord, the Rexnord PMC business, and Axxxx have not been reflected in the unaudited pro forma condensed combined financial information. Regal Rexnord believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Merger and the Debt Financing and, as applicable, the merger with the Rexnord PMC business, based on information available to Regal Rexnord’s management at this time and that the pro forma transaction accounting adjustments give effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information. Differences between these preliminary estimates and the final acquisition accounting may arise, and these differences could have a material impact on the accompanying unaudited pro forma condensed combined financial statements and the combined company’s future results of operations and financial position.
