⁽¹⁾Amounts may not sum due to rounding.

⁽²⁾Dilutive effect is only applicable to the periods during which GCP generated net income from continuing operations.

GCP uses the treasury stock method to compute diluted earnings (loss) per share. During the three months ended June 30, 2020, there were no anti-dilutive shares based on the treasury stock method as a result of a loss from continuing operations incurred during the period. During the six months ended June 30, 2020, 0.8 million of anti-dilutive stock awards were excluded from the computation of diluted earnings per share during each period based on the treasury stock method as a result of income from continuing operations generated during the periods then ended. During the three and six months ended June 30, 2019, 0.6 million of such anti-dilutive stock awards were excluded from the computation of diluted earnings per share.
