Such forward-looking statements may include, among other things, statements about the acquisition of Altra Industrial Motion Corp. (“Altra”), the benefits and synergies of the acquisition of Altra (the "Altra Transaction"), future opportunities for Regal Rexnord and any other statements regarding Regal Rexnord’s future operations, anticipated economic activity, business levels, credit ratings, future earnings, planned activities, anticipated growth, market opportunities, strategies, competition and other expectations and estimates for future periods.

These forward-looking statements are based upon information currently available to Regal Rexnord and are subject to a number of risks, uncertainties, and other factors that could cause Regal Rexnord's performance, prospects or opportunities to differ materially from those expressed in, or implied by, these forward-looking statements. Important factors that could cause Regal Rexnord’s actual results to differ materially from the results referred to in the forward-looking statements Regal Rexnord makes in this release include: Regal Rexnord’s substantial indebtedness as a result of the Altra Transaction and the effects of such indebtedness on Regal Rexnord's financial flexibility after the Altra Transaction; Regal Rexnord’s ability to achieve its objectives on reducing its indebtedness on the desired timeline; dependence on key suppliers and the potential effects of supply disruptions; fluctuations in commodity prices and raw material costs; any unforeseen changes to or the effects on liabilities, future capital expenditures, revenue, expenses, synergies, indebtedness, financial condition, losses and future prospects; the possibility that Regal Rexnord may be unable to achieve expected benefits, synergies and operating efficiencies in connection with the Altra Transaction, and the merger with the Rexnord Process & Motion Control business (the “Rexnord PMC business”) within the expected time-frames or at all and to successfully integrate Altra and the Rexnord PMC business; expected or targeted future financial and operating performance and results; operating costs, customer loss and business disruption (including, without limitation, difficulties in maintaining relationships with employees, customers, clients or suppliers) being greater than expected following the Altra Transaction or our merger with the Rexnord PMC business; Regal Rexnord’s ability to retain key executives and employees; uncertainties regarding the ability to execute restructuring plans within expected costs and timing; challenges to the tax treatment that was elected with respect to the merger with the Rexnord PMC business and related transactions; actions taken by competitors and their ability to effectively compete in the increasingly competitive global electric motor, drives and controls, power generation and power transmission industries; the ability to develop new products based on technological innovation, such as the Internet of Things, and marketplace acceptance of new and existing products, including products related to technology not yet adopted or utilized in geographic locations in which Regal Rexnord does business; dependence on significant customers and distributors; cyclical and seasonal impact on sales of products into particular markets and industries; risks associated with climate change and uncertainty regarding our ability to deliver on our climate commitments and/or to meet related investor, customer and other third party expectations relating to our sustainability efforts; risks associated with global manufacturing, including risks associated with public health crises and political, societal or economic instability, including instability caused by ongoing geopolitical conflicts; issues and costs arising from the integration of acquired companies and businesses and the timing and impact of purchase accounting adjustments; prolonged declines in one or more markets, such as heating, ventilation, air conditioning, refrigeration, power generation, oil and gas, unit material handling, water heating and aerospace; economic changes in global markets, such as reduced demand for products, currency exchange rates, inflation rates, interest rates, recession, government policies, including policy changes affecting taxation, trade, tariffs, immigration, customs, border actions and the like, and other external factors that Regal Rexnord cannot control; product liability, asbestos and other litigation, or claims by end users, government agencies or others that products or customers’ applications failed to perform as anticipated, particularly in high volume applications or where such failures are alleged to be the cause of property or casualty claims; unanticipated liabilities of acquired businesses; unanticipated adverse effects or liabilities from business exits or divestitures, including in connection with our proposed sale of the industrial motors and generators businesses that comprise a majority of our Industrial Systems operating segment (the "Proposed Sale”); the possibility that the conditions to the consummation of the Proposed Sale will not be satisfied on the terms or timeline expected, or at all; failure to obtain, or delays in obtaining, or adverse conditions related to obtaining regulatory approvals sought in connection with the Proposed Sale; Regal Rexnord's ability to identify and execute on future M&A opportunities, including significant M&A transactions; the impact of any such M&A transactions on Regal Rexnord's results, operations and financial condition, including the impact from costs to execute and finance any such transactions; unanticipated costs or expenses that may be incurred related to product warranty issues; infringement of intellectual property by third parties, challenges to intellectual property, and claims of infringement on third party technologies; effects on earnings of any significant impairment of goodwill; losses from failures, breaches, attacks or disclosures involving information technology infrastructure and data; costs and unanticipated liabilities arising from rapidly evolving data privacy laws and regulations; cyclical downturns affecting the global market for capital goods; and other risks and uncertainties including, but not limited, to those described in Regal Rexnord's Annual Report on Form 10-K on file with the Securities and Exchange Commission (the "SEC") and from time to time in other filed reports including Regal Rexnord's Quarterly Reports on Form 10-Q. For a more detailed description of the risk factors associated with Regal Rexnord, please refer to Part I, Item 1A - Risk Factors in Regal Rexnord’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 on file with the SEC and subsequent SEC filings. Shareholders, potential investors, and other readers are urged to consider these factors in evaluating the forward-looking statements and are cautioned not to place undue reliance on such forward-looking statements.

©2023 Regal Rexnord Corporation, Proprietary and Confidential Creating a better tomorrow™… NON-GAAP FINANCIAL MEASURES 3 4Q 2023 We prepare our financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We also periodically disclose certain financial measures in our quarterly earnings releases, on investor conference calls, and in investor presentations and similar events that may be considered “non-GAAP” financial measures. This additional information is not meant to be considered in isolation or as a substitute for our results of operations prepared and presented in accordance with GAAP. In this earnings release, we disclose the following non-GAAP financial measures, and we reconcile these measures in the tables below to the most directly comparable GAAP financial measures: adjusted diluted earnings per share, adjusted income from operations, adjusted operating margin, adjusted net sales, adjusted gross margin, net debt, EBITDA, adjusted EBITDA, proforma EBITDA, proforma adjusted EBITDA, proforma adjusted EBITDA (including synergies), interest coverage ratio, interest coverage ratio (including synergies), adjusted EBITDA margin, adjusted net income attributable to Regal Rexnord, adjusted cash flows from operations, adjusted free cash flow, adjusted free cash flow as a percentage of adjusted net income attributable to Regal Rexnord (or free cash flow conversion), adjusted income before taxes, adjusted provision for income taxes, and adjusted effective tax rate. We believe that these non-GAAP financial measures are useful measures for providing investors with additional information regarding our results of operations and for helping investors understand and compare our operating results across accounting periods and compared to our peers. Our management primarily uses adjusted income from operations and adjusted operating margin to help us manage and evaluate our business and make operating decisions, while the other non-GAAP measures disclosed are primarily used to help us evaluate our business and forecast our future results. Accordingly, we believe disclosing and reconciling each of these measures helps investors evaluate our business in the same manner as management. In addition to these non-GAAP measures, we use the term “organic sales growth” and "pro forma organic sales growth" to refer to the increase in our sales between periods that is attributable to organic sales. “Organic sales” refers to GAAP sales from existing operations excluding any sales from acquired businesses recorded prior to the first anniversary of the acquisition and excluding any sales from business divested/to be exited recorded prior to the first anniversary of the exit and excluding the impact of foreign currency translation. “Proforma organic sales” refers to "organic sales" giving effect to the acquisition of Altra. The impact of foreign currency translation is determined by translating the respective period’s organic sales using the currency exchange rates that were in effect during the prior year periods. The assumptions and related pro forma adjustments in the selected financial information presented within this release are consistent with those presented in the Company's Current Reports on Form 8-K filed on June 5, 2023 and September 8, 2023 giving effect to the acquisition of Altra and related transactions and are inclusive of the measurement period adjustments included in the Company's Annual Report on Form 10-K to be filed on February 23, 2024.
