(1)Diluted earnings per share does not reflect any incremental shares related to redeemable equity, as such instruments are not participating securities and do not give rise to potentially dilutive common shares. However, the accretion of redeemable equity to its redemption value is treated as a deemed dividend and reduces net income available to common shareholders in the calculation of both basic and diluted earnings per share. Accordingly, the impact of redeemable equity on earnings per share is limited to this income allocation adjustment, with no effect on the weighted-average shares outstanding.

(2)For the nine months ended September 30, 2026, the Company's net income reflects the accretion of redeemable non-controlling interest to its redemption value as of the reporting date. Diluted earnings per share for the nine months ended September 30, 2026 excludes 10.6 million weighted average shares of Class B common stock, as the effect would be anti-dilutive. Diluted earnings per share for the three and nine months ended September 30, 2025 excludes 11.2 million and 11.3 million weighted average shares of Class B common stock, as the effect would be anti-dilutive.
