[10-Q] Delta Air Lines, Inc. Quarterly Earnings Report

Rhea-AI Filing Summary

Citigroup Global Markets Holdings Inc., fully guaranteed by Citigroup Inc., has filed Product Supplement No. ES-01-10 to its March 7 2023 base prospectus and July 10 2025 prospectus supplement for future issuances of Equity-Linked Securities (ELKS), Callable Yield Securities, or other similarly structured notes (collectively, the “securities”). These medium-term senior notes (Series N) provide fixed coupon payments but do not assure repayment of principal. Repayment at maturity depends on the performance of one or more “Underlying Shares” – individual equities, American depositary shares (ADSs), exchange-traded funds (ETFs) or, in some structures, the worst performer among multiple underlyings.

Key structural terms (set in each future pricing supplement):

• Coupon rate and payment schedule.
• Definition of “Downside Event,” equity ratio, initial share price and downside threshold price.
• Choice of valuation method (closing price vs. intra-day trading price) and observation window (single-day, daily, or period-based testing).
• Issuer call right on specified dates (if applicable).
• Issuer option to settle in cash instead of delivering shares.

Principal risks highlighted:

• Loss of up to 100 % of principal if a downside event occurs; investors receive underlying shares (or cash equivalent) likely worth less than par.
• No participation in upside appreciation; return is capped at coupons.
• Credit risk of both Citigroup Global Markets Holdings Inc. and Citigroup Inc.; securities are senior unsecured obligations.
• Generally no exchange listing, hence limited secondary liquidity; potential reliance on Citigroup Global Markets as sole market-maker.
• Complex U.S. tax treatment; IRS may challenge issuer’s assumptions, and Section 871(m) withholding may apply to non-U.S. holders.
• Broad calculation-agent discretion (an affiliate of the issuer) in determining prices, adjustments and market-disruption resolutions, creating potential conflicts of interest.

The document incorporates extensive risk disclosures covering volatility sensitivity, dividend dilution, market-disruption events, delisting scenarios, ETF-specific considerations, emerging-market exposure, and tax uncertainties. Investors are directed to read this supplement together with the base prospectus, the July 10 2025 prospectus supplement, and the eventual pricing supplement for each issuance before investing.

Insights

Structured-Products Analyst

TL;DR Highly structured notes offering yield but expose investors to equity downside, no upside, and issuer credit risk.

The supplement outlines generic terms for future ELKS and similar securities. While coupon income may exceed plain-vanilla senior notes, investors substitute principal protection for equity risk without upside participation. Credit exposure to Citigroup adds another layer of risk. The lack of exchange listing limits liquidity, and calculation-agent discretion introduces conflicts. From a corporate perspective, the filing expands Citigroup’s structured-product toolkit but does not materially change its financial outlook. For investors, risk/return is appropriate only for those seeking yield enhancement with clear acceptance of potential full principal loss.

Tax & Regulatory Specialist

TL;DR Tax treatment is unsettled; withholding and retroactive rule changes could erode returns, especially for non-U.S. holders.

The supplement emphasizes the absence of clear IRS authority on prepaid forward-style instruments and flags Section 871(m) ‘dividend equivalent’ exposure. Future legislation or guidance could impose unexpected liabilities. The issuer will not gross-up for U.S. withholding taxes, shifting all burden to investors. These uncertainties heighten after-tax risk and should be modeled before purchase.

Forward Looking Statements

Unless otherwise indicated or the context otherwise requires, the terms "Delta," "we," "us" and "our" refer to Delta Air Lines, Inc. and its subsidiaries.

FORWARD-LOOKING STATEMENTS

Statements in this Form 10-Q (or otherwise made by us or on our behalf) that are not historical facts, including statements about our estimates, expectations, beliefs, intentions, projections, goals, aspirations, commitments or strategies for the future, may be "forward-looking statements" as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from historical experience or our present expectations. Known material risk factors applicable to Delta are described in "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 ("Form 10-K"), other than risks that could apply to any issuer or offering. All forward-looking statements speak only as of the date made, and we undertake no obligation to publicly update or revise any forward-looking statements to reflect events or circumstances that may arise after the date of this report except as required by law.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and the Stockholders of

Delta Air Lines, Inc.

Results of Review of Interim Financial Statements

We have reviewed the accompanying consolidated balance sheet of Delta Air Lines, Inc. (the Company) as of June 30, 2025, the related condensed consolidated statements of operations and comprehensive income and consolidated statements of stockholders' equity for the three-month and six-month periods ended June 30, 2025 and 2024, condensed consolidated statements of cash flows for the six-month periods ended June 30, 2025 and 2024 and the related notes (collectively referred to as the "condensed consolidated interim financial statements"). Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2024, the related consolidated statements of operations, comprehensive income, cash flows, and stockholders' equity for the year then ended, and the related notes (not presented herein); and in our report dated February 11, 2025, we expressed an unqualified audit opinion on those Consolidated Financial Statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2024, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission (SEC) and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Notes to the Condensed Consolidated Financial Statements

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Delta Air Lines, Inc. and our consolidated subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information. Consistent with these requirements, this Form 10-Q does not include all the information required by GAAP for complete financial statements. As a result, this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in our Form 10-K for the year ended December 31, 2024.

Management believes the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including normal recurring items, considered necessary for a fair statement of results for the interim periods presented.

Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and six months ended June 30, 2025 are not necessarily indicative of operating results for the entire year.

We reclassified certain prior period amounts to conform to the current period presentation. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes.

NOTE 2. REVENUE RECOGNITION

Passenger Revenue

			Three Months Ended June 30,									Six Months Ended June 30,
(in millions)			2025			2024						2025			2024
Ticket			$	12,246		$	12,349					$	22,314		$	22,182
Loyalty travel awards			1,092			975						2,033			1,820
Travel-related services			529			517						1,000			970
Passenger revenue			$	13,867		$	13,841					$	25,347		$	24,972

Ticket

We recognized approximately $5.7 billion and $5.6 billion in passenger revenue during the six months ended June 30, 2025 and 2024, respectively, that had been recorded in our air traffic liability balance at the beginning of those periods.

Loyalty Travel Awards

Loyalty travel awards revenue is related to the redemption of mileage credits ("miles") for air travel. Our SkyMiles loyalty program allows customers to earn miles by flying on Delta, Delta Connection and other airlines that participate in the loyalty program. Customers can also earn miles through participating companies, such as credit card, retail, ridesharing, car rental and hotel companies, who purchase miles from us. Our most significant contract to sell miles relates to our co-brand credit card relationship with American Express. During the six months ended June 30, 2025 and 2024, total cash sales from marketing agreements related to our loyalty program were $4.0 billion and $3.6 billion, respectively, which are allocated to travel and other performance obligations.

Current Activity of the Loyalty Program. Miles are combined in one homogeneous pool and are not separately identifiable. Therefore, revenue is comprised of miles that were part of the loyalty program deferred revenue balance at the beginning of the period as well as miles that were issued during the period. The timing of mile redemptions can vary widely; however, the majority of miles have historically been redeemed within two years of being earned.

Delta Air Lines, Inc. | June 2025 Form 10-Q 7

Notes to the Condensed Consolidated Financial Statements

The table below presents the activity of the current and noncurrent loyalty program deferred revenue and includes miles earned through travel and miles sold to participating companies, which are primarily through marketing agreements.

Balance at January 1						$	8,826		$	8,420

Miles redeemed for non-air travel and other						(109)			(114)
Balance at June 30						$	9,071		$	8,634

Travel-Related Services

Travel-related services are primarily composed of services performed in conjunction with a passenger’s flight and include baggage fees, administrative fees and on-board sales. We recognize revenue for these services when the related transportation service is provided.

Revenue by Geographic Region

Operating revenue for the airline segment is recognized in a specific geographic region based on the origin, flight path and destination of each flight segment. A significant portion of the refinery segment's revenues typically consists of fuel sales to support the airline, which is eliminated in the Condensed Consolidated Financial Statements. The remaining operating revenue for the refinery segment is included in the domestic region. Our passenger and operating revenue by geographic region is summarized in the following tables:

Long-term investments and related			2,372			2,085			160			127
Fuel hedge contracts			(17)			—			(17)			—

Cash Equivalents and Restricted Cash Equivalents. Cash equivalents generally consist of money market funds. Restricted cash equivalents generally consist of money market funds, time deposits, commercial paper and negotiable certificates of deposit. Restricted cash equivalents primarily relate to proceeds from debt issued to finance, among other things, a portion of the construction costs for our new terminal facilities at New York's LaGuardia Airport as well as certain self-insurance obligations and airport commitments. Restricted cash equivalents are recorded in other noncurrent assets and prepaid expenses and other on our Consolidated Balance Sheet ("balance sheet"). The fair value of these cash equivalents is based on a market approach using prices generated by market transactions involving identical or comparable assets.

Long-Term Investments and Related. Our long-term investments measured at fair value primarily consist of equity investments, which are valued based on market prices or other observable transactions and inputs, and are recorded in equity investments on our balance sheet. Our equity investments in private companies are classified as Level 3 in the fair value hierarchy as their equity is not traded on a public exchange and our valuations incorporate certain unobservable inputs, including non-public equity issuances. Fair value measurement using unobservable inputs is inherently uncertain, and a change in significant inputs could result in different fair values. See Note 4, "Investments," for further information on our equity investments.

Fuel Hedge Contracts. Our derivative contracts to hedge the financial risk from changing fuel prices are related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe"). We recognized gains of $53 million and $33 million on our fuel hedge contracts in aircraft fuel and related taxes on our Condensed Consolidated Statements of Operations and Comprehensive Income ("income statement") for the three and six months ended June 30, 2025, respectively, compared to gains of $16 million and losses of $80 million for the three and six months ended June 30, 2024, respectively. The gains recognized during the first six months of 2025 were composed of $32 million of mark-to-market gains and $1 million of settlement gains on contracts. Gains and losses on settled contracts are reflected within Monroe's operating results. See Note 9, "Segments," for further information on our refinery segment.

NOTE 9. SEGMENTS

Refinery Operations

Our refinery segment operates for the benefit of the airline segment by providing jet fuel to the airline segment from its own production and from jet fuel obtained through agreements with third parties. The refinery's production consists of jet fuel, as well as non-jet fuel products. We use several counterparties to exchange non-jet fuel products produced by the refinery for jet fuel consumed in our airline operations.

Segment Reporting

NOTE 10. EARNINGS PER SHARE

We calculate basic earnings per share by dividing net income by the weighted average number of common shares outstanding, excluding restricted shares. We calculate diluted earnings per share by dividing net income by the weighted average number of common shares outstanding plus the dilutive effect of outstanding share-based instruments, including stock options, restricted stock awards and warrants. Antidilutive common stock equivalents excluded from the diluted earnings per share calculation are not material. The following table shows the computation of basic and diluted earnings per share:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Condensed Consolidated Financial Statements and the related notes and other financial information included elsewhere in this Quarterly Report on Form 10-Q and our audited Consolidated Financial Statements and related notes included in our 2024 Form 10-K.

June 2025 Quarter Financial Highlights

Our operating income for the June 2025 quarter was $2.1 billion, a decrease of $165 million compared to the June 2024 quarter.

Revenue. Compared to the June 2024 quarter, our total revenue decreased $10 million. Passenger revenue increased $26 million compared to the June 2024 quarter on an increase in revenue for premium products and loyalty travel awards, partially offset by a decline in main cabin due to reduced consumer and corporate confidence caused by macroeconomic uncertainty particularly early in the June 2025 quarter. Total revenue, adjusted (a non-GAAP financial measure, which excludes revenue related to refinery sales to third parties) increased in the June 2025 quarter by $100 million, or 1%, compared to the June 2024 quarter.

Operating Expense. Total operating expense in the June 2025 quarter increased $155 million, or 1%, compared to the June 2024 quarter, primarily due to costs associated with a 4% increase in capacity, higher employee costs from increased wages, and increased landing fees and other rents largely offset by lower aircraft fuel and related taxes. Total operating expense, adjusted (a non-GAAP financial measure, which primarily excludes expenses related to refinery sales to third parties) in the June 2025 quarter increased $320 million, or 2%, compared to the June 2024 quarter, primarily due to costs associated with the increase in capacity, largely offset by lower aircraft fuel and related taxes.

Our total operating cost per available seat mile ("CASM") decreased 3% compared to the June 2024 quarter, while non-fuel unit cost ("CASM-Ex", a non-GAAP financial measure) increased 2.7%.

Cash Flow. Our cash, cash equivalents, short-term investments and aggregate undrawn principal amount available under our revolving credit facilities ("liquidity") as of June 30, 2025 was $6.4 billion.

During the June 2025 quarter, operating activities generated $1.9 billion, primarily from ticket sales and the sale of SkyMiles to our partners. Total cash sales to American Express were approximately $2.0 billion in the June 2025 quarter, an increase of approximately 10% compared to the June 2024 quarter.

Cash flows used in investing activities during the quarter totaled $1.2 billion primarily from capital expenditures. These operating and investing activities yielded free cash flow (a non-GAAP financial measure) of $733 million in the June 2025 quarter. Additionally, we issued $2.0 billion in aggregate principal amount of unsecured notes and had cash outflows of $2.9 billion related to repayments of our debt and finance leases, including using a portion of the proceeds from the notes offering to repay the Payroll Support Program loan due 2030 ("PSP1 Loan").

The non-GAAP financial measures referenced above for total revenue, adjusted, operating expense, adjusted, CASM-Ex and free cash flow are defined and reconciled in "Supplemental Information" below.

(2)Total Revenue per available seat mile ("TRASM"), adjusted is a non-GAAP financial measure. For additional information on adjustments to TRASM, see "Supplemental Information" below.

Compared to the June 2024 quarter, total revenue decreased $10 million, due to a decrease in main cabin ticket revenue offset by strength in demand for premium products and long-haul international travel.

Domestic

Domestic passenger revenue decreased 1% in the June 2025 quarter compared to the June 2024 quarter on a 4% increase in capacity. Domestic revenue decreased due to a reduction in main cabin ticket revenue on reduced consumer and corporate demand caused by macroeconomic uncertainty particularly early in the June 2025 quarter.

International

International passenger revenue for the June 2025 quarter increased compared to the June 2024 quarter. The Atlantic region continues to experience strong demand for travel as we expanded service to European destinations compared to the prior year. Our Pacific region revenue reflects the continued maturation of our joint ventures and network restoration.

Refinery. Refinery sales to third parties decreased $110 million compared to the June 2024 quarter. See "Refinery Segment" below for additional details on the refinery's operations, including third party refinery sales.

Loyalty Program. This relates to revenues from brand usage by third parties and other performance obligations embedded in miles sold, as well as redemption of miles for non-air travel and other awards. These revenues are mainly driven by customer spend on American Express cards and new cardholder acquisitions.

Ancillary Businesses. This includes revenues from aircraft maintenance services we provide to third parties and our vacation package operations. The increase is attributable to higher volume of engine repairs by our aircraft maintenance services operation during the current quarter.

Miscellaneous. This is primarily composed of revenues related to lounge access, including access provided to certain American Express cardholders, codeshare agreements and certain other commercial relationships.

Total operating expense			$	14,546		$	14,391					$	155		1		%

Salaries and Related Costs. The increase in salaries and related costs primarily resulted from the implementation of base pay increases for eligible employees of 5% effective June 1, 2024 and 4% effective June 1, 2025, and 4% for Delta pilots on January 1, 2025.

Aircraft Fuel and Related Taxes. Aircraft fuel and related taxes decreased $355 million compared to the June 2024 quarter primarily due to a 17% decrease in the market price of jet fuel partially offset by an increase in consumption consistent with the 4% increase in capacity. We expect that fuel consumption for the remainder of 2025 will increase compared to 2024 aligned with capacity, partially offset by improvements in the fuel efficiency from our new aircraft acquisitions. The refinery generated a one cent incremental cost per gallon compared to a benefit of six cents per gallon in the June 2024 quarter. We expect jet fuel prices to remain volatile.

See "Refinery Segment" below for additional details on the refinery's operations.

Contracted Services. The increase in contracted services results from inflationary rate increases in our operations and volume increases on a 4% increase in capacity.

Landing Fees and Other Rents. The increase in landing fees and other rents resulted from higher rates charged by airports following extensive redevelopment projects at numerous facilities and more flights compared to the June 2024 quarter.

Regional Carrier Expense. The increase in regional carrier expense primarily resulted from higher volume of regional flights.

Aircraft Maintenance Materials and Outside Repairs. The decrease in aircraft maintenance materials and outside repairs expense primarily resulted from the timing of maintenance activities.

Aircraft Fuel and Related Taxes. Aircraft fuel and related taxes decreased $541 million compared to the six months ended June 30, 2024 due to a 15% decrease in the market price per gallon of jet fuel. The refinery generated a one cent incremental cost per gallon compared to a benefit of five cents per gallon in the six months ended June 30, 2024.

See "Refinery Segment" below for additional details on the refinery's operations.

Total non-operating expense, net			$	472		$	(494)					$	966					$	224		$	(986)		$	1,210

Interest expense, net. Interest expense, net includes interest expense and interest income. This decreased compared to the prior year primarily due to reduced interest expense resulting from our debt reduction initiatives. During 2024, we made payments of $4.0 billion related to our debt and finance lease obligations. We have continued to pay down our debt during the six months ended June 30, 2025 with $3.5 billion of payments on debt and finance lease obligations. During the June 2025 quarter, we issued $2.0 billion in aggregate principal amount of unsecured notes and used a portion of the proceeds to repay the PSP1 Loan. The new unsecured notes carry a lower interest rate than the PSP1 Loan repaid. We continue to seek opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities, and refinance higher cost debt.

Gain/(loss) on investments, net. Changes in the valuation of investments accounted for at fair value are recorded in gain/(loss) on investments, net and 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. See Note 4 of the Notes to the Condensed Consolidated Financial Statements for additional information on our equity investments measured at fair value on a recurring basis.

Loss on extinguishment of debt. Loss on extinguishment of debt reflects the losses incurred in the early repayment of certain loans and notes.

Miscellaneous, net. Miscellaneous, net primarily includes employee benefit plans net periodic cost, charitable contributions, our share of our equity method investments' results, dividends received from our equity investees and foreign exchange gains/(losses).

Income Taxes

We project our annual effective tax rate for 2025 will be between 22% and 25%. In certain periods, we may have adjustments to our net deferred tax liabilities as a result of changes in prior year estimates, mark-to-market adjustments on our equity investments and tax laws enacted during the period, which will impact the effective tax rate for that period.

Delta Air Lines, Inc. | June 2025 Form 10-Q 23

Item 2. MD&A - Refinery Segment

Refinery Segment

The refinery operated by Monroe primarily produces gasoline, diesel and jet fuel. Monroe exchanges non-jet fuel products the refinery produces with third parties for jet fuel consumed in our airline operations. The jet fuel produced and procured through exchanging gasoline and diesel fuel produced by the refinery typically provides approximately 200,000 barrels per day, or approximately 75% of our consumption, for use in our airline operations. The refinery regularly optimizes its sales and exchange activities based on market conditions. The refinery generated a small operating loss in the six months ended June 30, 2025 compared to operating income in the six months ended June 30, 2024, primarily as a result of lower pricing of refined products.

For more information regarding the refinery's results, see Note 9 of the Notes to the Condensed Consolidated Financial Statements.

Item 2. MD&A - Financial Condition and Liquidity

Financial Condition and Liquidity

As of June 30, 2025, we had $6.4 billion in cash, cash equivalents, short-term investments and aggregate undrawn principal amount available under our revolving credit facilities. We expect to meet our liquidity needs for the next twelve months with cash and cash equivalents and cash flows from operations. We expect to meet our long-term liquidity needs with cash flows from operations and financing arrangements.

Undrawn Lines of Credit. As of June 30, 2025, we had approximately $3.1 billion undrawn and available under our revolving credit facilities.

Sources and Uses of Liquidity

Operating Activities

We generated cash flows from operations of $4.2 billion and $4.9 billion in the six months ended June 30, 2025 and 2024. We expect to continue generating positive cash flows from operations during the remainder of 2025.

Our operating cash flow is impacted by the following factors:

Seasonality of Advance Ticket Sales. We sell tickets for air travel in advance of the customer's travel date. When we receive a cash payment at the time of sale, we record the cash received on advance sales as deferred revenue in air traffic liability. The air traffic liability typically increases during the winter and spring months as advance ticket sales grow prior to the summer peak travel season and decreases during the summer and fall months.

Fuel. Fuel expense represented approximately 17% and 20% of our total operating expense for the six months ended June 30, 2025 and 2024, respectively. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. Fuel consumption was higher during the three and six months ended June 30, 2025 compared to the prior year period due to the increase in capacity. We expect that fuel consumption for the remainder of 2025 will increase compared to 2024 aligned with capacity, partially offset by improvements in the fuel efficiency from our new aircraft acquisitions.

Profit Sharing. We paid $1.4 billion in profit sharing payments in February 2025 related to our 2024 pre-tax profit in recognition of our employees' contributions toward achieving the year's financial results.

Our broad-based employee profit sharing program provides that for each year in which we have an annual pre-tax profit, as defined by the terms of the program, we will pay a specified portion of that profit to eligible employees. In determining the amount of profit sharing, the program defines profit as pre-tax profit adjusted for profit sharing and certain other items. During the six months ended June 30, 2025, we accrued $594 million in profit sharing expense based on the year-to-date performance and current expectations for 2025 profit.

Sale of Miles to Participating Companies. Customers earn miles based on their spending with participating companies such as credit card, retail, ridesharing, car rental and hotel companies with which we have marketing agreements to sell miles. Payments are typically due to us monthly based on the volume of miles sold during the period. Our most significant contract to sell miles relates to our co-brand credit card relationship with American Express. Total cash sales to American Express were $3.9 billion in the six months ended June 30, 2025, an increase of 9% compared to the prior year period. See Note 2 of the Notes to the Condensed Consolidated Financial Statements for further information regarding the cash sales from marketing agreements.

Item 2. MD&A - Financial Condition and Liquidity

Investing Activities

Capital Expenditures. Our capital expenditures were $2.4 billion and $2.5 billion for the six months ended June 30, 2025 and 2024, respectively. We have committed to future aircraft purchases and have obtained, but are under no obligation to use, long-term financing commitments for a substantial portion of the purchase price of the aircraft. Our expected 2025 capital spend of approximately $5.0 billion will be primarily for aircraft, including deliveries and advance deposit payments, as well as fleet modifications and technology enhancements.

Financing Activities

Debt and Finance Leases. In the six months ended June 30, 2025, we had cash outflows of $3.5 billion related to repayments of our debt and finance lease obligations. We continue to seek opportunities to pre-pay our debt, in addition to periodic amortization and scheduled maturities, and refinance higher cost debt.

In June 2025, we issued $2.0 billion in aggregate principal amounts of unsecured notes, consisting of $1.0 billion of 4.95% Notes due 2028 and $1.0 billion of 5.25% Notes due 2030 (collectively, the "Notes"). The net proceeds from the offering of the Notes were used to repay the PSP1 Loan and for general corporate purposes.

In February 2025, Moody's credit rating agency upgraded its rating for Delta to Baa2, an investment grade rating.

See Note 5 of the Notes to the Condensed Consolidated Financial Statements for further information on our debt agreements.

Capital Return to Shareholders. On April 24, 2025, the Board of Directors approved a quarterly dividend of $0.15 per share which we paid on June 3, 2025 for total cash dividends of $97 million. Total cash dividends for the six months ended June 30, 2025 were $196 million.

On June 18, 2025, the Board of Directors approved a quarterly dividend of $0.1875 per share to shareholders of record as of July 31, 2025, which we will pay on August 21, 2025.

In the June 2025 quarter, the Board of Directors authorized a $1.0 billion opportunistic share repurchase program open through June 30, 2028. No shares were repurchased under this program in the June 2025 quarter.

Covenants. We were in compliance with the covenants in our debt agreements at June 30, 2025.

Critical Accounting Estimates

There have been no material changes in our Critical Accounting Estimates from the information provided in the "Critical Accounting Estimates" section of "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Form 10-K.

Item 2. MD&A - Supplemental Information

Supplemental Information

We sometimes use information (non-GAAP financial measures) that is derived from the Condensed Consolidated Financial Statements, but that is not presented in accordance with 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.

Included below are reconciliations of non-GAAP measures used within this Form 10-Q to the most directly comparable GAAP financial measures. Reconciliations below may not calculate exactly due to rounding. These reconciliations include certain adjustments to GAAP measures 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.

•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.

Item 2. MD&A - Supplemental Information

Free Cash Flow

The following table shows a reconciliation of net cash provided by operating and used in investing activities (GAAP measures) to free cash flow (a non-GAAP financial measure). 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. Adjustments include:

•Pension plan contributions. Cash flows related to pension funding are included in our GAAP operating activities. We adjust to exclude these contributions to allow investors to understand the cash flows related to our core 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 because management believes investors should be informed that a portion of these capital expenditures from airport construction projects are either reimbursed by a third party or funded with restricted cash specific to these projects.

The following table presents information with respect to purchases of common stock we made during the June 2025 quarter. The table reflects shares withheld from employees to satisfy certain tax obligations due in connection with grants of stock under the Delta Air Lines, Inc. Performance Compensation Plan (the "Plan"). The Plan provides for the withholding of shares to satisfy tax obligations. It does not specify a maximum number of shares that can be withheld for this purpose.
