The potentially dilutive employee stock options, restricted share units and performance share units that were antidilutive were immaterial and 1 million for the three and six months ended December 31, 2023, respectively. The potentially dilutive employee stock options, restricted share units and performance share units that were antidilutive were 3 million and 5 million for the three and six months ended December 31, 2022, respectively. For both the three and six months ended December 31, 2022, there were 2 million potentially dilutive employee stock options, restricted share units and performance share units not included in the computation of diluted loss per common share attributable to Cardinal Health, Inc. because their effect would have been antidilutive as a result of the net loss during those periods.
