Supplemental Unaudited Pro-Forma—The unaudited consolidated financial information summarized in the following table gives effect to all acquisitions completed in 2024 assuming they occurred on January 1, 2024. These unaudited consolidated pro-forma operating results do not assume any impact from revenue, cost or other operating synergies that are expected or may have been realized as a result of the acquisitions. These unaudited consolidated pro forma operating results include results from certain acquired companies that have not been audited and whose accounting policies prior to acquisition may differ from those of the Company. As a result, these unaudited consolidated pro forma operating results may not be comparable to revenues and earnings had these consolidated pro forma results been audited and consistent accounting policies applied. These unaudited consolidated pro-forma operating results are presented for illustrative purposes only and are not indicative of the operating results that would have been achieved had the acquisitions occurred on January 1, 2024 nor does the information project results for any future period. Please refer to the Company's 2024 Form 10-K for information regarding the 2024 acquisitions.
