(2) Excludes approximately 220,000 shares of RSUs that would have been anti-dilutive to EPS under the treasury stock method for the three months ended June 30, 2024. Also excludes approximately 316,000 and 208,000 shares of RSUs that would have been anti-dilutive to EPS under the treasury stock method for the three and six months ended June 30, 2023. These RSUs could potentially dilute EPS in the future.

(3) Excludes approximately 14,000 shares of PSUs that would have been anti-dilutive to EPS under the treasury stock method for the three months ended June 30, 2024. Also excludes approximately 60,000 and 38,000 shares of PSUs that would have been anti-dilutive to EPS under the treasury stock method for the three and six months ended June 30, 2023. These PSUs could potentially dilute EPS in the future.

(4) Excludes approximately 1,212,000 shares of Options that would have been anti-dilutive to EPS under the treasury stock method for the three months ended June 30, 2024. Also excludes approximately 735,000 and 635,000 shares of Options that would have been anti-dilutive to EPS under the treasury stock method for the three and six months ended June 30, 2023. These Options could potentially dilute EPS in the future.
