On June 30, 2023, the Separation from Labcorp was effected through a pro-rata distribution of one share of the Company’s common stock for every share of Labcorp common stock held at the close of business on the record date of June 20, 2023. As a result, on June 30, 2023, the Company had 88.8 shares of common stock outstanding. This share amount is being utilized for the calculation of basic earnings per share for all periods presented through the Separation date. As of the Separation date, actual outstanding shares are used to calculate basic weighted average common shares outstanding. Basic earnings per share is computed by dividing net earnings attributable to the Company by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing net earnings including the impact of dilutive adjustments by the weighted average number of common shares outstanding plus potentially dilutive shares, as if they had been issued at the earlier of the date of issuance or the beginning of the period presented. Potentially dilutive common shares result primarily from the Company’s outstanding stock options, restricted stock awards, restricted stock units, and performance share awards.

Diluted earnings per share represent the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. These potential shares include dilutive stock options and unissued restricted stock awards. Potential common shares are also considered antidilutive in the event of a net loss from operations.
