In addition, the Company has also included within Exhibit 99.1 information for the three-months ended June 30, 2023, which is consistent with the information presented in the Company's Current Report on Form 8-K filed on August 1, 2023 for the second quarter 2023 financial results. The assumptions and related pro forma adjustments in the selected unaudited pro forma financial information presented within Exhibit 99.1 are consistent with those presented in the Company's Current Report on Form 8-K filed on June 5, 2023 in connection with the acquisition and related transactions and are inclusive of the measurement period adjustments included in the Company's Quarterly Report on Form 10-Q filed on August 4, 2023. The selected unaudited pro forma information gives effect to the acquisition and related transactions as if they occurred on January 1, 2022. These estimates should not be viewed as a substitute for full unaudited pro forma condensed consolidated financial statements prepared in accordance with Article 11 of Regulation S-X. The pro forma information presented within Exhibit 99.1 does not reflect the Company's actual results or expectations of future performance, and the Company's actual future financial results may differ significantly from the pro forma information presented herein. Non-GAAP Measures 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 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 the selected unaudited pro forma financial information presented within Exhibit 99.1, we disclose the following non-GAAP financial measures, and we reconcile these measures to the most directly comparable GAAP financial measures: adjusted net sales, proforma adjusted net sales, proforma EBITDA, adjusted EBITDA, proforma adjusted EBITDA, adjusted EBITDA margin, proforma adjusted EBITDA margin, adjusted income from operations, proforma adjusted income from operations, adjusted operating margin, and proforma adjusted operating margin. 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” 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. 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.
