1.Restricted stock units are considered participating securities due to the Company's practice of paying dividend equivalents on unvested shares.

2.Share amounts for the year ended December 31, 2018 were based on 2,246.3 million DowDuPont common shares outstanding as of the Record Date for the April 1, 2019 distribution, less 4.6 million Employee Stock Ownership Plan ("ESOP") shares that had not been released and were not considered outstanding, adjusted for the Distribution Ratio. There was no dilutive effect for the year ended December 31, 2018 as the Company did not engage in activities giving rise to dilution.

3.The year ended December 31, 2019 reflected a loss from continuing operations, and as such, the basic share count was used for purposes of calculating earnings per share on a diluted basis.

4.These outstanding options to purchase shares of common stock and restricted stock units were excluded from the calculation of diluted earnings per share because the effect of including them would have been antidilutive. For the year ended December 31, 2018, the Company did not engage in activities giving rise to dilution.
