Delta Air Lines posts higher revenue but lower operating income, net income, and diluted EPS year over year on both the three-month and six-month reporting windows

Bottom line

For the three-month reporting period the three months ended June 30, 2026 and the six-month year-to-date period the six months ended June 30, 2026, DELTA AIR LINES, INC. — reporting under 10-Q for period-ended-2026-06-30 and filed under accession 0000027904-26-000031 (CIK 0000027904, ticker DAL) — recorded lower Earnings Per Share, Diluted ($2.44 per diluted share, $2 per diluted share) than the prior-year comparatives ($3.27 per diluted share, $3.63 per diluted share), lower Net Income (Loss) Attributable to Parent ($1,604,000,000, $1,315,000,000) than the prior-year comparatives ($2,130,000,000, $2,370,000,000), and lower Operating Income (Loss) ($1,864,000,000, $2,365,000,000) than the prior-year comparatives ($2,102,000,000, $2,671,000,000), while Revenue from Contract with Customer, Excluding Assessed Tax was higher than the prior-year comparative for both windows ($19,757,000,000, $35,611,000,000 versus $16,648,000,000, $30,688,000,000). The headline answer for this section is that all three profit metrics contracted year over year on both windows while the top line expanded year over year on both windows. This shape — top line up, bottom lines down — mirrors the pattern seen in other recent earnings write-ups in the same coverage stream, such as Broadcom Posts Higher Revenue, Operating Income, and Diluted EPS Year-Over-Year in Filing, where the same revenue-versus-margin framing is used to anchor the reader before drilling into details. The source scope for this analysis is the unaudited Condensed Consolidated Financial Statements presented in this 10-Q, together with the auditor review report dated July for the three-month and six-month periods ended June.

Management Discussion / Explanation Management states that 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. It cautions that, 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 are not necessarily indicative of operating results for the entire year. Management further notes that it reclassified certain prior period amounts to conform to the current period presentation and that, unless otherwise noted, all amounts disclosed are stated before consideration of income taxes. The filing also flags the pending Environmental Credits and Environmental Credit Obligations accounting standard, which management is assessing for potential impact on future Consolidated Financial Statements.

Analyst Inference Reading only the authorized direction list, the pattern is straightforward: revenue moved higher year over year on both windows (the three months ended June 30, 2026 and the six months ended June 30, 2026), while each of the three profit metrics — Earnings Per Share, Diluted, Net Income (Loss) Attributable to Parent, and Operating Income (Loss) — moved lower year over year on both windows, with each line remaining in profit in both the current and prior periods. The filing evidence does not attribute this change to any single cause.

Counter-Evidence None was identified within the narrative excerpt. The auditor review report is unqualified as to material modifications, and management's only explicit caveat is the standard seasonality and fuel-volatility language, which is forward-looking caution rather than a contradiction of the reported figures.

Unknowns A segment-level breakdown of revenue or operating income is not disclosed within the excerpt surfaced for this section; per the catalog, that detail would fall under the segment-related note if cited in full. The filing evidence contains no peer or industry comparison.

Financial performance

- For the three-month reporting period, Revenue from Contract with Customer, Excluding Assessed Tax was $19,757,000,000 USD, compared with $16,648,000,000 USD in the prior-year quarter — an authorized direction increase, with both periods remaining in profit. - For the six-month year-to-date period, Revenue from Contract with Customer, Excluding Assessed Tax was $35,611,000,000 USD, versus $30,688,000,000 USD in the prior-year half — an authorized direction increase, with both periods remaining positive. - For the three-month reporting period, Operating Income (Loss) was $1,864,000,000 USD, compared with $2,102,000,000 USD in the prior-year quarter — an authorized direction decrease, with both periods still in profit and an authorized profit-to-profit transition.

- For the six-month year-to-date period, Operating Income (Loss) was $2,365,000,000 USD, versus $2,671,000,000 USD in the prior-year half — an authorized direction decrease, with both periods still in profit and an authorized profit-to-profit transition. - For the three-month reporting period, Net Income (Loss) Attributable to Parent was $1,604,000,000 USD, compared with $2,130,000,000 USD in the prior-year quarter — an authorized direction decrease, with both periods still in profit and an authorized profit-to-profit transition.

- For the six-month year-to-date period, Net Income (Loss) Attributable to Parent was $1,315,000,000 USD, versus $2,370,000,000 USD in the prior-year half — an authorized direction decrease, with both periods still in profit and an authorized profit-to-profit transition. 27 per diluted share USD/SHARES in the prior-year quarter — an authorized direction decrease, with both periods still positive and an authorized profit-to-profit transition. 63 per diluted share USD/SHARES in the prior-year half — an authorized direction decrease, with both periods still positive and an authorized profit-to-profit transition.

- The filing evidence does not attribute this change to any single cause. - Reported facts — Revenue moved higher on both windows while Operating Income, Net Income and Diluted EPS each moved lower; the filing does not attribute the divergence between the top-line and the lower-line movements to any single cause. - Management explanations — Management notes seasonal variation in air-travel demand, volatility in aircraft fuel prices, and other factors that make interim results not necessarily indicative of full-year outcomes; the company also discloses reclassifications of prior-period amounts to conform to the current presentation.

- Analyst inference — Across the four headline measures on both the quarter and the half-year, the top-line (revenue) is authorized as higher than the prior period while the three profitability measures (operating income, net income, diluted EPS) are each authorized as lower than the prior period, leaving each profitability metric still in positive territory versus the prior period; this is a classic "revenue up, margins softer" shape, though the catalog does not authorize a margin ratio and no margin figure is asserted here.

- Counter-evidence — None within the catalog. The filing does not present a peer or industry comparison, and no contrary direction is authorized; a comparable profit-to-profit pattern is described for other recent interim filings such as the Lizely Finance Earnings Analysis — UFP TECHNOLOGIES INC Interim Filing: Profit-to-Profit Growth on Both Windows and the Lizely Finance Earnings Analysis — ANI Pharmaceuticals Interim Filing: Profit-to-Profit Growth on Both Windows, but those references are illustrative only.

- Unknowns — Segment-level results are not in this section's fact catalog, and the filing's discussion of refinery segment revenue recognition is captured only at a high level; the Note 9 segment footnote is acknowledged but not asserted numerically here.

Operating drivers and segments

- The filing references a refinery segment alongside the airline segment in the revenue-by-geographic-region note, and points readers to Note 9 for the underlying revenue recognition policy. Note 9 is the only segment-level reference surfaced for this section, and it does not disclose split revenue, unit cost, or contribution margin between the airline and the refinery. - Operating Income (Loss) is reported by DELTA AIR LINES, INC. at $1,864,000,000 USD for the three-month reporting period the three months ended June 30, 2026 and at $2,365,000,000 USD for the six-month period the six months ended June 30, 2026. The prior-year comparators are $2,102,000,000 USD for the three months ended June 30, 2025 and $2,671,000,000 USD for the six months ended June 30, 2025. The authorized period-over-period direction for Operating Income (Loss) is a decrease on both the quarter and half-year windows, while both the current and prior periods remain in profit, consistent with a profit-to-profit transition. - Revenue from Contract with Customer, Excluding Assessed Tax is recorded at $19,757,000,000 USD for the three months ended June 30, 2026 and $35,611,000,000 USD for the six months ended June 30, 2026, against $16,648,000,000 USD for the three months ended June 30, 2025 and $30,688,000,000 USD for the six months ended June 30, 2025. The authorized direction is an increase on both windows, so top-line moved up while operating-income moved down at the consolidated level on a period-over-period basis; the gap itself is not interpreted here, only flagged. - No segment-level revenue, cost, or margin table is reproduced in the available evidence. The geographic-region disclosure also states that fuel sales from the refinery to the airline are eliminated in consolidation, with the residual refinery revenue slotted into the domestic region, which limits how much can be inferred about segment economics from the consolidated lines.

- Management describes the period-over-period movements without attributing them to a single driver in the disclosed text; the "Forward Looking Statements" preamble notes that known material risk factors applicable to Delta are described in Item 1A of the most recent Annual Report and that all forward-looking statements speak only as of the date made, with no obligation to update except as required by law. - The accounting-policies note flags seasonal variation in air-travel demand, aircraft-fuel-price volatility, and other factors as reasons the three- and six-month results are not necessarily indicative of full-year operating results, and states that certain prior-period amounts were reclassified to conform to the current presentation; this is consistent with the customary interim-disclosure caution rather than with a specific cause-and-effect claim. - Management confirms that the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments considered necessary for a fair statement of results for the interim periods presented, and that the statements should be read together with the prior-year audited financial statements referenced in the review report.

Cash flow and capital

The cash flow statement for the six-month period covered by this interim filing shows the classic airline split between strong day-to-day generation and heavy capital demands. Net cash provided by operating activities was positive for the period, as reported under 10-Q for the six months ended June 30, 2026, continuing a pattern of positive operating cash generation seen in the prior-year comparative for the six months ended June 30, 2025; on a year-over-year basis, operating cash flow decreased against the prior year, with current and prior figures drawn from $4,027,000,000 and $4,235,000,000 respectively. The filing evidence does not attribute this change to any single cause.

Investing activity remained a net use of cash, reflecting continued fleet and infrastructure spending typical of a carrier of DELTA AIR LINES, INC.'s scale. The investing line for the six months ended June 30, 2026 came in negative, lower (i.e., a smaller outflow) than the prior-year comparative for the six months ended June 30, 2025, based on -$2,775,000,000 and -$2,423,000,000. Financing activity also stayed negative across both windows, with the current six-month figure and the prior-year comparative drawn from -$980,000,000 and -$1,704,000,000; year-over-year, the cash used in financing increased (became a larger outflow) against the prior period. The filing evidence does not attribute this change to any single cause.

The balance sheet at the balance sheet date of June 30, 2026 provides the snapshot behind these flows. Cash and cash equivalents, at carrying value, stood at the level reported under $4,665,000,000, while accounts payable, current, were recorded at $6,738,000,000. Long-term debt, excluding current maturities, was reported at $10,101,000,000, reflecting the substantial long-dated borrowings that the filing's notes describe, including the SkyMiles term loan credit facility amendment referenced in the source narrative. The interplay between operating cash inflow, investing outflow, and financing outflow leaves liquidity roughly balanced between cash on hand and supplier obligations, with long-term debt continuing to anchor the right-hand side of the balance sheet.

On capital returns to shareholders, the six-month period recorded dividend payments of $252,000,000, compared with $196,000,000 for the prior-year window. Year-over-year, dividend payments increased against the prior period, indicating a stepped-up cash return to shareholders despite the wider reduction in operating cash flow. The filing evidence does not attribute this change to any single cause.

Broader liquidity items referenced elsewhere in the filing, including restricted cash equivalents tied to self-insurance obligations, debt-related reserves and airport commitments, sit outside the cash and cash equivalents balance and are recorded in prepaid expenses and other noncurrent assets rather than in the headline cash figure. The filing evidence contains no peer or industry comparison.

Peer and historical context

- Year-over-year context drawn from DELTA AIR LINES, INC.'s own prior periods sits inside this filing under 10-Q for period-ended-2026-06-30 (accession 0000027904-26-000031, CIK 0000027904, ticker DAL), so any comparison written here is internal, not against named competitors. - The filing evidence contains no peer or industry comparison.

When a filing stands alone, the only peer an analyst really has is the company itself a year ago. The filing evidence for DELTA AIR LINES, INC. under 10-Q for period-ended-2026-06-30 does exactly that, restating the prior-year column so the reader can line up three-month and six-month totals side by side. That gives the section a usable historical reference, but it does not give a peer reference, and that asymmetry needs to be acknowledged up front.

On the top line, Revenue from Contract with Customer, Excluding Assessed Tax moved higher year over year on both windows. The three-month window for the three months ended June 30, 2026 came in at $19,757,000,000 USD, above the $16,648,000,000 USD reported for the three months ended June 30, 2025. The six-month window for the six months ended June 30, 2026 landed at $35,611,000,000 USD, also above the $30,688,000,000 USD figure for the six months ended June 30, 2025. The authorized direction on both comparisons is "increase", so the reported moves are consistent with the pre-cleared year-over-year calls and do not need any narrative correction here.

Operating Income (Loss) tells the opposite story on both windows, even though it stayed in profit territory in each period. The current three-month result of $1,864,000,000 USD for the three months ended June 30, 2026 is lower than the $2,102,000,000 USD recorded for the three months ended June 30, 2025, and the six-month result of $2,365,000,000 USD for the six months ended June 30, 2026 is lower than the $2,671,000,000 USD recorded for the six months ended June 30, 2025. The authorized direction on both comparisons is "decrease" with the transition labeled "profit to profit", so the historical comparison can be reported as a contraction in operating profit, not a swing into a loss.

Net Income (Loss) Attributable to Parent follows the same pattern: lower than a year ago on both windows, still a profit in every column. For the three months ended June 30, 2026 the current figure is $1,604,000,000 USD versus $2,130,000,000 USD for the three months ended June 30, 2025; for the six months ended June 30, 2026 it is $1,315,000,000 USD versus $2,370,000,000 USD for the six months ended June 30, 2025. The authorized direction here is again "decrease" with a "profit to profit" transition.

On cash generation, the only year-over-year comparison the filing evidence supports is Net Cash Provided by (Used in) Operating Activities for the six-month window. The current period came in at $4,027,000,000 USD for the six months ended June 30, 2026, lower than $4,235,000,000 USD for the six months ended June 30, 2025. The authorized direction is "decrease" with both columns remaining positive, so this reads as a softer cash-generating year rather than a swing into a cash burn.

Because every line item above is a year-over-year change drawn from the same filing, The filing evidence does not attribute this change to any single cause. applies to all of them; the filing does not attribute any of the revenue growth, operating-income contraction, net-income decline, or softer operating cash flow to a single cause. Readers looking for an external cross-reference can compare the same shape — higher revenue with lower operating profit — in Broadcom Posts Higher Revenue, Operating Income, and Diluted EPS Year-Over-Year in the reporting period Filing, but that link is illustrative only, because The filing evidence contains no peer or industry comparison. remains true for DELTA AIR LINES, INC. specifically.

Scenario analysis

- Top-line context for the base case rests on Revenue from Contract with Customer, Excluding Assessed Tax of $35,611,000,000 for the six months ended June 30, 2026 and $19,757,000,000 for the three months ended June 30, 2026, with both windows showing higher than the prior-year comparatives of $30,688,000,000 and $16,648,000,000 under the authorized direction. - Profitability on the base case reflects Net Income (Loss) Attributable to Parent of $1,315,000,000 for the six months ended June 30, 2026 and $1,604,000,000 for the three months ended June 30, 2026, each lower than the prior-year comparatives of $2,370,000,000 and $2,130,000,000 under the authorized direction, and each remaining in a profit-to-profit transition. - The base path therefore is sustained top-line growth alongside continued but reduced bottom-line profitability on both the six-month and three-month reporting windows.

- A constructive trajectory assumes Revenue from Contract with Customer, Excluding Assessed Tax continues to expand on both the six months ended June 30, 2026 and the three months ended June 30, 2026 relative to the prior-year comparatives already reported, building on the directionally higher readings of $35,611,000,000 versus $30,688,000,000 and $19,757,000,000 versus $16,648,000,000. - On the profit side, an upside path would require Net Income (Loss) Attributable to Parent of $1,315,000,000 and $1,604,000,000 to hold above the lower prior-year comparatives of $2,370,000,000 and $2,130,000,000, sustaining the profit-to-profit transition. - Refinancing actions described in the cited note, including the SkyMiles Credit Facility amendment and the Corporate Revolving Credit Facility replacement, leave the issuer with variable-rate exposure to adjusted term SOFR plus a margin, so an upside outcome is sensitive to the path of short-term rates relative to the spread locked in at closing. - For context on how peer issuers have handled comparable revenue-and-profit splits, see Broadcom Posts Higher Revenue, Operating Income, and Diluted EPS Year-Over-Year in Filing.

- A weaker trajectory assumes the already-lower Net Income (Loss) Attributable to Parent readings of $1,315,000,000 versus $2,370,000,000 and $1,604,000,000 versus $2,130,000,000 continue to compress, even as Revenue from Contract with Customer, Excluding Assessed Tax of $35,611,000,000 and $19,757,000,000 remains directionally above $30,688,000,000 and $16,648,000,000. - Equity investments classified as Level 3 in the fair value hierarchy remain sensitive to unobservable inputs and non-public equity issuances, and a downside path exposes the issuer to further mark-to-market movement in those positions. - Variable-rate borrowings under the credit facilities described in the cited note carry exposure to adjusted term SOFR plus a margin, so a downside path includes the risk of higher interest expense relative to the current base. - The filing evidence contains no peer or industry comparison to anchor a downside read against the wider sector. The filing evidence contains no peer or industry comparison. - The filing evidence does not disclose segment-level detail for these dimensions beyond the segment reference in the cited note. The filing evidence does not disclose segment-level detail for this dimension. - The filing evidence does not attribute the lower net income to any single cause. The filing evidence does not attribute this change to any single cause.

Risks and what to watch

- Reported facts: for the three-month reporting period, DELTA AIR LINES, INC. reported Net Income (Loss) Attributable to Parent of $1,604,000,000 USD, against a prior-year comparative of $2,130,000,000 USD; on a six-month year-to-date basis, the figure stood at $1,315,000,000 USD versus $2,370,000,000 USD in the prior period. Revenue from Contract with Customer, Excluding Assessed Tax was $19,757,000,000 USD for the quarter (prior year: $16,648,000,000 USD) and $35,611,000,000 USD for the half year (prior year: $30,688,000,000 USD).

- Management explanations: the filing's narrative points to three concrete areas that frame downside risk. First, the SkyMiles term loan refinancing was repriced to a variable rate based on an adjusted term SOFR plus a margin, with a prepayment premium attaching to a Repricing Event within six months of the amendment — meaning an early re-pricing within that window would crystallise an additional cost. Second, the Corporate Revolving Credit Facility was refinanced into three-year and five-year variable-rate tranches, leaving both the loyalty financing and the corporate revolver more exposed to a higher-rate environment than a fixed-rate structure would be.

Third, the discussion of fair value of debt explicitly frames the risk as a potential reduction in fair value and a negative impact to future earnings from an increase in interest rates. - Analyst inference: with earnings higher on the quarter but revenue higher year over year on the same window, the spread between the two lines is the headline tension. On the half year the authorised comparison shows net income moving down while revenue moves up, and the operating-income and EPS comparisons on the same window likewise show a decrease against higher revenue — a profit-margin compression rather than a top-line shortfall.

The authorised cash-flow comparisons add context: operating cash flow is positive but lower than the prior year, financing and investing flows remain negative, and dividend payments are larger than the prior period. Together these point to a period where cash returned to shareholders rose while internal generation softened. - Counter-evidence: the filing does disclose the refinery-segment revenue recognition mechanics via the cited segment note, but does not separate refinery contribution from passenger revenue on the face of the statements, which can either flatter or obscure the headline top line depending on commodity moves.

The fair-value disclosure is a tiered presentation using the cited Level inputs, and the level-three cash equivalents line shows no carrying balance — limiting how much volatility can be inferred from that ladder. - Unknowns: the filing does not attribute the divergence between revenue and net income to any single cause, so The filing evidence does not attribute this change to any single cause. applies to the gap between the authorised revenue direction and the authorised net-income direction on the half year.

Segment-level detail beyond the cited refinery note is not disclosed here, so The filing evidence does not disclose segment-level detail for this dimension. applies to any airline-versus-refinery split for this period. The filing evidence contains no peer or industry comparison, so The filing evidence contains no peer or industry comparison.

applies to any read on competitors' margins. Aircraft purchase commitments of roughly (omitted) billion are disclosed, but the timing of those commitments and their impact on cash flow are not quantified here. - Metrics to watch next period: the spread between revenue growth and net income on a half-year basis; the variable-rate exposure on both the SkyMiles facility and the corporate revolver against any move in the underlying rate index; the level of dividend payments versus the prior period; the refinery segment contribution flagged in the cited segment note; and any disclosure about the fuel hedge contracts referenced in the cited investments note.
