Revenue Environment and Outlook

"We generated record March quarter revenues, 6 percent higher than the prior year. Total unit revenue (TRASM) was down 0.7 percent compared to last year, including a nearly one-point headwind from Cargo and MRO. This result was at the high end of our guidance, with the growth rate improving three points from the December quarter," said Glen Hauenstein, Delta’s president.

“Strong demand for travel on Delta is continuing into the June quarter where we expect total revenue growth of 5 to 7 percent compared to the June quarter 2023 on TRASM of flat to down 2 percent. Within this outlook, all geographic entities are expected to achieve unit revenue approximately flat to last year, except Latin, where we expect a double-digit decline as we lap strong performance and continue to profitably invest in the network.”

| • | Record March quarter revenue: Delta delivered March quarter revenue that was 6 percent higher than 2023 driven by best-in-class operations and strong demand trends. Delta led the industry in completion factor and on-time performance, and operated 26 cancel-free, brand-perfect days in the quarter. Adjusted total unit revenue (TRASM) growth improved 3 points sequentially from the December quarter 2023 to down 0.7 percent year-over-year, including a nearly one-point headwind from cargo and MRO.
| • | Corporate travel demand accelerated: Managed corporate sales* grew 14 percent year-over-year, led by the return of large corporate accounts, particularly in the Technology, Consumer Services and Financial Services sectors. Recent corporate survey results indicate that 90 percent of companies expect their travel volumes to increase or stay the same in the June quarter and beyond.
| • | Domestic environment improved with robust demand: Domestic unit revenues were a March quarter record, growing 3 percent year-over-year with record domestic load factors. Unit revenues improved 7 points sequentially from the December quarter 2023, inflecting positive for the March quarter.
| • | International travel strength continued: International passenger revenue was 12 percent higher versus the March quarter 2023, with Transatlantic passenger unit revenue (PRASM) up 2 percent. International passenger unit revenues were down 3 percent on 16 percent higher capacity as Delta continued to invest in rebuilding the Latin and Pacific networks.
| • | Revenue diversification driving Delta's differentiation: For the quarter, diversified revenue streams, including Loyalty, Premium, Cargo and MRO comprised 57 percent of total revenues. Premium revenue grew 10 percent versus the March quarter 2023, continuing to outperform Main Cabin. Loyalty revenue was up 12 percent, driven by continued co-brand spend growth and increasing premium card mix. Remuneration from American Express for the March quarter was $1.7 billion, approximately 5 percent higher than the March quarter 2023.

*Corporate sales include tickets sold to corporate contracted customers, including tickets for travel during and beyond the referenced time period

Cost Performance and Outlook

“For the March quarter, we delivered pre-tax income of $380 million, an improvement of $163 million over last year. Delta’s operational excellence resulted in the best March quarter completion factor in our history, providing an incremental point of capacity growth and unit cost favorability with non-fuel unit costs 1.5 percent higher than last year,” said Dan Janki, Delta’s chief financial officer.

“Growth is normalizing and we are in a period of optimization, with a focus on restoring our most profitable core hubs and delivering efficiency gains. For the June quarter, non-fuel unit costs are expected to increase approximately 2 percent, consistent with our full year outlook for a low single-digit increase in non-fuel unit costs over 2023.”

Note A: The following tables show reconciliations of non-GAAP financial measures. The reasons Delta uses these measures are described below. Reconciliations may not calculate due to rounding.

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 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 tables below show reconciliations of non-GAAP financial measures used in this release to the most directly comparable GAAP financial measures.

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.

Adjustments. These reconciliations include certain adjustments to GAAP measures that are made to provide comparability between the reported periods, if applicable, and for the reasons indicated below:

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.

MTM adjustments and settlements on hedges. Mark-to-market ("MTM") adjustments are defined as fair value changes recorded in periods other than the settlement period. Such fair value changes are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period, and therefore we remove this impact to allow investors to better understand and analyze our core performance. Settlements represent cash received or paid on hedge contracts settled during the applicable period.

One-time pilot agreement expenses. In the March 2023 quarter, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement included a provision for a one-time payment made upon ratification in the March 2023 quarter of $735 million. Additionally, we recorded adjustments to other benefit-related items of approximately $130 million. Adjusting for these expenses allows investors to better understand and analyze our core cost performance.

MTM adjustments on investments. Unrealized gains/losses result from our equity investments that are accounted for at fair value in non-operating expense. The gains/losses are driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in certain companies, particularly those without publicly-traded shares. Adjusting for these gains/losses allows investors to better understand and analyze our core operational performance in the periods shown.

Loss on extinguishment of debt. This adjustment relates to early termination of a portion of our debt. Adjusting for these losses allows investors to better understand and analyze our core operational performance in the periods shown.

Operating Cash Flow, adjusted. We present operating cash flow, adjusted because management believes adjusting for the following items provides a more meaningful measure for investors:

Net cash flows related to certain airport construction projects and other. Cash flows related to certain airport construction projects are included in our GAAP operating activities. We have adjusted for these items, which were primarily funded by cash restricted for airport construction, to provide investors a better understanding of the company's operating cash flow that is core to our operations in the periods shown.

Pilot agreement payment. In March 2023, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement includes a provision for a one-time payment upon ratification in the March 2023 quarter of $735 million. We adjust for this item to provide investors a better understanding of our recurring cash flow generated by our operations.

Free Cash Flow. We present free cash flow because management believes this metric is helpful to investors to evaluate the company's ability to generate cash that is available for use for debt service or general corporate initiatives. Free cash flow is also used internally as a component of our incentive compensation programs. Free cash flow is defined as net cash from operating activities and net cash from investing activities, adjusted for (i) net purchases/(redemptions) of short-term investments, (ii) net cash flows related to certain airport construction projects and other, (iii) financed aircraft acquisitions and (iv) pilot agreement payment. These adjustments are made for the following reasons:

Net purchases/(redemptions) of short-term investments. Net purchases/(redemptions) of short-term investments represent the net purchase and sale activity of investments and marketable securities in the period, including gains and losses. We adjust for this activity to provide investors a better understanding of the company's free cash flow generated by our operations.

Net cash flows related to certain airport construction projects and other. Cash flows related to certain airport construction projects are included in our GAAP operating activities and capital expenditures. We have adjusted for these items, which were primarily funded by cash restricted for airport construction, to provide investors a better understanding of the company's free cash flow and capital expenditures that are core to our operations in the periods shown.

Financed aircraft acquisitions. This adjustment reflects aircraft deliveries that are leased as capital expenditures. The adjustment is based on their original contractual purchase price or an estimate of the aircraft's fair value and provides a more meaningful view of our investing activities.

Pilot agreement payment. In March 2023, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement includes a provision for a one-time payment upon ratification in the March 2023 quarter of $735 million. We adjust for this item to provide investors a better understanding of our recurring free cash flow generated by our operations.

Adjusted Debt to Earnings Before Interest, Taxes, Depreciation, Amortization and Rent ("EBITDAR"). We present adjusted debt to EBITDAR because management believes this metric is helpful to investors in assessing the company's overall debt profile. Adjusted debt includes operating lease liabilities and sale leaseback liabilities. We calculate EBITDAR by adding depreciation and amortization to GAAP operating income and adjusting for the fixed portion of operating lease expense.

After-tax Return on Invested Capital ("ROIC"). We present after-tax return on invested capital as management believes this metric is helpful to investors in assessing the company's ability to generate returns using its invested capital as a measure against the industry. Return on invested capital is tax-effected adjusted total pre-tax income divided by average adjusted invested capital. Average adjusted invested capital represents the sum of the adjusted book value of equity at the end of the last five quarters, adjusted for pension impacts within other comprehensive income. Average adjusted gross debt is calculated using amounts as of the end of the last five quarters. All adjustments to calculate ROIC are intended to provide a more meaningful comparison of our results to the airline industry.

Amortization of retirement actuarial loss. This adjustment relates to actuarial gains/losses on our benefit plans. Adjusting for these results allows investors to better understand our core operational performance in the periods shown as it removes prior period differences in assumptions and actual experience within our benefit plans.

Interest expense, net and interest expense included in aircraft rent. This adjustment relates to interest expense related to debt and financing transactions. Adjusting for these results allows investors to better understand our core operational performance in the periods shown as it neutralizes the effect of our capital structure.

Adjusted Non-Fuel Cost and Non-Fuel Unit Cost or Cost per Available Seat Mile, ("CASM-Ex")

We adjust operating expense and CASM for certain items described above, as well as 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.

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.

Gross Capital Expenditures. We adjust capital expenditures for the following items to determine gross capital expenditures for the reasons described below:

Financed aircraft acquisitions. This adjusts capital expenditures to reflect aircraft deliveries that are leased as capital expenditures. The adjustment is based on their original contractual purchase price or an estimate of the aircraft's fair value and provides a more meaningful view of our investing activities.

Net cash flows related to certain airport construction projects. Cash flows related to certain airport construction projects are included in capital expenditures. We have adjusted for these items because management believes investors should be informed that a portion of these capital expenditures from airport construction projects are either funded with restricted cash specific to these projects or reimbursed by a third party.

Adjusted Net Debt. Delta uses adjusted total debt, including aircraft rent, in addition to adjusted debt and finance leases, to present estimated financial obligations. Delta reduces adjusted total debt by cash, cash equivalents, short-term investments and LGA restricted cash, resulting in adjusted net debt, to present the amount of assets needed to satisfy the debt. Management believes this metric is helpful to investors in assessing the company's overall debt profile.
