(1)Income allocation is based on the weighted-average number of as-converted class A common stock outstanding as shown in the table below.
(2)Figures in the table may not recalculate exactly due to rounding. Basic and diluted earnings per share are calculated based on unrounded numbers.
(3)Diluted class A common stock earnings per share calculation includes the assumed conversion of any class B-1, B-2 and C common stock and participating securities on an as-converted basis as shown in the table below and the incremental common stock equivalents related to employee stock plans, as calculated under the treasury stock method. For the three and six months ended March 31, 2026 and 2025, the common stock equivalents were not material for each period.
