Earnings Per Share [Abstract]  
EARNINGS PER SHARE EARNINGS PER SHARE
Basic EPS is computed by dividing Net earnings attributable to Labcorp Holdings Inc. by the weighted-average number of common shares outstanding. Diluted EPS is computed by dividing Net earnings attributable to Labcorp Holdings Inc., and if applicable, 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 units, and/or performance share awards.
The following represents a reconciliation of Basic EPS to Diluted EPS:
