Item 7.01 Regulation FD Disclosure. The information contained in this Current Report on Form 8-K, including the accompanying Exhibit 99.1, is being furnished pursuant to Item 2.02 and 7.01 of Form 8-K and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of that section. The information contained in this Current Report on Form 8-K that is furnished under this Item 2.02 and 7.01, including the accompanying Exhibit 99.1, shall not be incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof, except as shall be expressly set forth by specific reference in such a filing. Segment Reorganization On January 22, 2024, Brown & Brown, Inc. (the “Company”) issued a press release announcing that in conjunction with the divestiture of certain businesses within the Company’s Services segment in the fourth quarter of 2023, it had aligned its business from four to three segments beginning in 2024. As a result of the segment reorganization, the Services segment was eliminated as a business segment. Effective for fiscal year 2024, which began January 1, 2024, the Company will report its financial results in the following three reportable segments: Retail, Programs and Wholesale Brokerage. The Company’s new business segment structure reflects that the ongoing operations that had been part of the Services segment were integrated into the operation and management of the Retail segments, where the services provided more closely align with the services in Retail than they do with the Company’s other ongoing segments. The historical results for the businesses that were sold were combined with the Programs segment as they either derived a certain portion of their business from activities associated with managing general underwriter (MGU) programs in this segment or have similar customers to other businesses in the Programs segment. Supplemental Information The Company is providing Exhibit 99.1 to this Current Report on Form 8-K, as supplemental information, unaudited historical business segment information for each quarter of the Company’s fiscal year 2023 and for each of the full years from 2019 -2023, as recast to reflect the new business segment structure. Exhibit 99.1 is furnished herewith and is incorporated herein by reference. The segment reorganization has no impact to the Company’s previously reported consolidated statements of income, balance sheets, statements of cash flows, statements of comprehensive income or statements of shareholders’ equity. The Company did not operate under the realigned segment structure for any of these prior periods. The information in this Current Report on Form 8-K, including Exhibit 99.1, should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and the Company’s Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2023, June 30, 2023 and September 30, 2023, which reports have previously been filed with the Securities and Exchange Commission.
