Adjustment To PEO Compensation, Footnote

(2)

The table below describes the adjustments, each of which is required by SEC rules, to calculate the CAP amounts from the SCT Totals of our PEO (columns (b) and (c)) and the average CAP amounts from the average SCT Totals of the Other NEOs (columns (d) and (e)). The SCT Totals and CAP amounts do not reflect the actual amount of compensation earned by or paid to our named executive officers during the applicable years. In accordance with SEC rules, values for awards that vested on December 31, 2024 and awards that were outstanding and unvested as of December 31, 2024 were based on the $60.50 closing price of Delta common stock on the NYSE on December 31, 2024. If the values of the awards were based on average closing price of Delta common stock on the NYSE from March 5, 2025 to April 15, 2025 (i.e., $45.06), then the CAP amount for the PEO would have been $39,739,925.

Award Timing Disclosure	12 Months Ended
Award Timing Disclosure	Dec. 31, 2024
Awards Close in Time to MNPI Disclosures [Table]
Award Timing MNPI Disclosure	Delta’s equity award grant policy provides objective and standardized criteria for the timing, practices and procedures used in granting equity awards. Under this policy, the Personnel & Compensation Committee generally will consider approval of annual equity awards for management employees in the first quarter of the calendar year. However, if circumstances arise and the Personnel & Compensation Committee determines that it is advisable to grant equity awards at another time, it may decide to do so. Once approved, the grant date of these awards will be the later of (1) the date the Personnel & Compensation Committee approves the awards and (2) the third business day following the date on which Delta publicly announces its financial results for the most recently completed fiscal year. Equity awards for new hires, promotions or other off-cycle grants may be approved as appropriate and, once approved, these awards will be made on the later of (1) the date on which the grant is approved and (2) the third business day following the date on which Delta publicly announces its quarterly or annual financial results if this date is in the same month as the grant. Although Delta does not currently grant stock option awards to employees, the equity award grant policy prohibits the granting of stock options or option-like instruments to officers who are subject to Section 16 of the Securities Act of 1933 during the period starting four business days before and ending one business day after the filing of Delta’s 10-K or Form 10-Q or the filing or furnishing of a Form 8-K that discloses material non-public information.
