During the three months ended June 30, 2026 and 2025, weighted-average shares related to certain stock options of 1.8 and 1.9, respectively, were excluded from the denominator for diluted shareholders' earnings per share because the stock options were anti-dilutive. During the six months ended June 30, 2026 and 2025, weighted-average shares related to certain stock options of 1.8 and 1.7, respectively, were excluded from the denominator for diluted shareholders' earnings per share because the stock options were anti-dilutive.
We have issued approximately 0.8 cumulative restricted stock units under our stock incentive plans, of which vesting is contingent upon us meeting specified earnings and qualitative plan performance targets. Contingent restricted stock units are excluded from the denominator for diluted shareholders’ earnings per share and are included only if and when the contingency is met. These contingent restricted stock units are being measured over a three-year period and generally vest in March of the year following each measurement period.
