(1)	On October 1, 2026, in connection with Corteva's spin-off of its Seed business (the "Spin-off"), the Reporting Person's Performance Stock Units ("PSUs") granted prior to 2026 were adjusted in accordance with the Employee Matters Agreement, dated October 1, 2026 between Corteva and Vylor Inc. ("EMA") and converted into Restricted Stock Units ("RSUs") based on attainment of performance up to the completion of the Spin-off. The RSUs remain subject to the same time-based vesting conditions as the original PSU award. This amount includes dividend equivalent units ("DEUs") associated with the converted PSUs.
(2)	In connection with the Spin-Off, the Reporting Person's 2026 RSU award was adjusted utilizing the employer method defined under the EMA with an adjustment ratio of 6.2722 (the "Adjustment Ratio"). This amount reported represents the difference between the original grant and the grant as adjusted by the Adjustment Ratio. This amount includes DEUs associated with the converted RSUs.
(3)	In connection with the Spin-off, the exercise price for option awards were adjusted utilizing the employer method defined under the EMA by dividing the original grant price by the Adjustment Ratio.
(4)	In connection with the Spin-off, the number of options were adjusted utilizing the employer method defined under the EMA by multiplying the original number of options by the Adjustment Ratio.
(5)	The original option was granted on February 28, 2023 and is now fully vested and exercisable.
(6)	The original option was granted on February 20, 2024 and 14,005 options are vested and exercisable. The remaining options will vest on 2/20/2027.
(7)	The original option was granted on February 18, 2025 and 5,707 options are vested and exercisable. The remaining options will vest in two equal installments on February 18, 2027 and February 18, 2028.
