Form 8-K dated February 6, 2025 Exhibit 99.1, page 1 1. We note you presentation of pro forma adjusted diluted earnings per share from continuing operations. The numerator used to compute this measure, the pro forma adjusted net income from continuing operations, includes the net income attributable to noncontrolling shareholders. The denominator, pro forma weighted average shares used in this calculation, includes Class A shares plus all dilutive potential shares. It appears that this calculation includes measures which substitute individually tailored recognition and measurement methods for those of GAAP. Please tell us how you considered Question 100.04 of the Non-GAAP Financial Measures Compliance and Disclosure Interpretations. 2. We note you present several non-GAAP measures: pro forma adjusted income before taxes from continuing operations, pro forma adjusted net income from continuing operations, pro forma adjusted diluted earnings per share from continuing operations and pro forma weighted average shares of adjusted diluted Class A common stock March 12, 2025 Page 2 outstanding. Please explain why these measures are labelled as pro forma as these measures do not appear to be consistent with Article 11 of Regulation S-X. Refer to Question 100.05 of the Non-GAAP Financial Measures Compliance and Disclosure Interpretations. Also please expand disclosure to clarify the purpose of these non- GAAP measures, how management uses them and why management believes they are useful to investors.
