NOTE 4: NET EARNINGS PER SHARE AND SHARE REPURCHASES

Our basic and diluted earnings per share were:

●

$0.11 during third quarter 2025 and$0.35 during year-to-date 2025;

●

$0.04 during third quarter 2024 and$0.43 during year-to-date 2024.

Basic earnings per share is net earnings divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued. Diluted earnings per share is net earnings divided by the sum of the weighted average number of our outstanding common shares and the effect of our outstanding dilutive potential common shares.

We use the treasury stock method to calculate the dilutive effect of our outstanding stock options, restricted stock units and performance share units.

Potential Shares Not Included in the Computation of Diluted Earnings per Share

The following shares were not included in the computation of diluted earnings per share because they were either antidilutive or the required performance or market conditions were not met. Some or all of these shares may be dilutive potential common shares in future periods.

On May 8, 2025, we announced the board approved a new share repurchase program (the 2025 Repurchase Program) under which we are authorized to repurchase up to $1 billion of outstanding shares. Concurrently, the board of directors terminated the completed purchase authorization under the 2021 Repurchase Program.
