We are also planning to reclassify certain Loyalty-related revenue line items to better align with how we operate. In 2025, the MRO business secured a record backlog and grew revenue 25% over prior year while generating a high-single digit operating margin. In 2026, the company expects MRO revenue to grow greater than 20% year over year, with outsized growth expected in the first half of 2026. Over the next several years, the company is positioned to more than double MRO revenue and improve operating margin to the mid-teens. Reporting updates include: Revenue presentation: • MRO: Beginning in 2026, MRO will be reported as a separate line item. In 2025, MRO revenue was included within Ancillary businesses, within Other revenue. • Loyalty-related revenue stream alignment: Beginning in 2026, Delta is planning to reclassify certain revenue streams from Ancillary businesses and Miscellaneous into the Loyalty program line within Other revenue. This will better reflect how the company manages the business. Expense presentation: • MRO expenses will be reported as a separate line item rather than within Ancillary businesses and refinery. In addition, Delta will separate MRO from the adjusted non-fuel unit cost metric to preserve visibility into Delta’s core airline cost trends. The table below provides historical information on MRO revenue and expenses. .2

Non-GAAP Reconciliations Non-GAAP Financial Measures Delta sometimes uses information ("non-GAAP financial measures") that is derived from the Consolidated Financial Statements, but that is not presented in accordance with accounting principles generally accepted in the U.S. (“GAAP”). Under the U.S. Securities and Exchange Commission rules, non-GAAP financial measures may be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. The table below shows reconciliations of non-GAAP financial measures used in this presentation to the most directly comparable GAAP financial measures. Reconciliations may not calculate due to rounding. Forward Looking Projections. Delta is not able to reconcile forward looking non-GAAP financial measures without unreasonable effort because the adjusting items such as those used in the reconciliations below will not be known until the end of the period and could be significant. Non-Fuel Unit Cost or Cost per Available Seat Mile, adjusted ("CASM-Ex") We adjust CASM for the following items and reasons described below: Aircraft fuel and related taxes. The volatility in fuel prices impacts the comparability of year-over-year financial performance. The adjustment for aircraft fuel and related taxes allows investors to better understand and analyze our non-fuel costs and year-over-year financial performance. Third-party refinery sales. Refinery sales to third parties, and related expenses, are not related to our airline segment. Excluding these sales therefore provides a more meaningful comparison of our airline operations to the rest of the airline industry. Profit sharing. We adjust for profit sharing because this adjustment allows investors to better understand and analyze our recurring cost performance and provides a more meaningful comparison of our core operating costs to the airline industry. MRO expense. We adjust for MRO expenses because this adjustment allows investors to better understand and analyze our recurring cost performance and provides a more meaningful comparison of our core operating costs to the airline industry.
