1.Share amounts for all periods prior to the Corteva Distribution were based on 748.8 million shares of Corteva, Inc. common stock distributed to holders of DowDuPont's common stock on June 1, 2019, plus 0.6 million of additional shares in which accelerated vesting conditions have been met.

2.Diluted earnings per share considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares would have an anti-dilutive effect.

3.These outstanding potential shares of common stock relating to stock options, restricted stock units and performance-based restricted stock units were excluded from the calculation of diluted earnings per share because the effect of including them would have been anti-dilutive.
