    Flagged areas: Solvency & liquidity.

    Why this surfaced

    The full financial analysis shows each value, threshold, and sector limitation.

  • Operating margin was stable

    Operating margin changed -0.5 percentage points from the prior annual period.

    Why this surfaced

    Direction threshold: more than +1 percentage point constructive; below -1 point caution. Period end 2025-12-31.

  • Revenue expanded

    Latest reported annual revenue changed +2.8% from the prior reported annual observation.

    Why this surfaced

    Direction threshold: above +2% constructive; below -2% caution; otherwise monitor. This is not labeled one-year growth when filing periods have a gap. Period end 2025-12-31.

  • Free cash flow was positive

    Latest reported free cash flow was $3.8B.

    Why this surfaced

    Free cash flow = operating cash flow minus capital expenditures; positive is supporting evidence, not a valuation conclusion. Period end 2025-12-31.

Each filer's latest fiscal year as stored by the nightly crawl; fiscal year ends differ across the universe. A metric ranks only filers for which it is computable from filed facts. Ties split; a rank reads "better than N% of filers" in the metric's own direction. Descriptive and educational, not a rating.

Per fiscal year from filed facts: cash conversion = operating cash flow / net income (net income > 0); cash-flow accrual ratio = (net income - operating cash flow) / average total assets; balance-sheet accrual ratio = change in net operating assets / average net operating assets, NOA = (assets - cash) - (liabilities - debt). Descriptive; a missing input yields a missing ratio. High accrual ratios and cash conversion well below one are the measures the accruals literature associates with less persistent earnings; they are screens to read the cash-flow statement with, not conclusions.

first-reported vs latest filing · periods since 2020-01-01 · 0 changed periods

No period on file has changed between its first report and the latest filing carrying it.

First filing reporting each period vs the latest filing carrying it (10-K and 10-Q only, periods since 2020, the extractor's winning tag per concept); a change under 0.5% is treated as rounding. A change can be a restatement, a reclassification or a re-tagging in a later comparative column; the two filings are linked so the reader can see which. Descriptive, not a verdict.

Fair value · 4,730 characters as filed

"FAIR VALUE MEASUREMENTS Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or liability. Each fair value measurement is classified into one of the following levels based on the information used in the valuation: Level 1. Observable inputs such as quoted prices in active markets. Level 2. Inputs, other than quoted prices in active markets, that are observable either directly or indirectly. Level 3. Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Assets and liabilities measured at fair value are based on the valuation techniques identified in the tables below. The valuation techniques are as follows: (a) Market Approach. Prices and other relevant information generated by observable transactions involving identical or comparable assets or liabilities. (b) Income Approach. Techniques to convert future amounts to a single present value amount based on market expectations (including present value techniques and option-pricing models).

Goodwill and intangibles · 5,140 characters as filed

GOODWILL AND INTANGIBLE ASSETS Goodwill and Indefinite-Lived Intangible Assets Our goodwill and identifiable intangible assets relate to the airline segment. We apply a fair value-based impairment test to the carrying value of goodwill and indefinite-lived intangible assets on an annual basis (as of October 1) and, if certain events or circumstances indicate that an impairment loss may have been incurred, on an interim basis. We assess the value of our goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Under a qualitative approach, we consider various market factors, including certain of the key assumptions listed below. We analyze these factors to determine if events and circumstances have affected the fair value of goodwill and indefinite-lived intangible assets. If we determine that it is more likely than not that the asset may be impaired, we use the quantitative approach to assess the asset's fair value and the amount of the impairment. Under a quantitative approach, we calculate the fair value of the asset incorporating the key assumptions listed below into our calculation. We value goodwill and indefinite-lived intangible assets primarily using market and income approach valuation techniques. These measurements include the following key assumptions (1) forecasted revenues, expenses and cash flows, (2) current discount rates, (3) observable market transactions and (4) anticipated changes to the regulatory environment (e.g., changes

Leases · 7,484 characters as filed

"LEASES We lease property and equipment under finance and operating leases. For leases with terms greater than 12 months, we record the related asset and obligation at the present value of the fixed minimum lease payments over the term. Many of our leases include rental escalation clauses, renewal options and/or termination options that are factored into our determination of lease payments when appropriate. We do not separate lease and nonlease components of contracts, except for regional aircraft and information technology (""IT"") assets as discussed below. We use the rate implicit in the lease to discount lease payments to present value, when readily determinable. When the rate implicit in the lease is not readily determinable, we use our incremental borrowing rate, which is based on the estimated interest rate for collateralized borrowing over a similar term of the lease at commencement date. Some of our aircraft lease agreements include provisions for residual value guarantees. These guarantees represent an immaterial portion of our lease liability. Aircraft As of December 31, 2025, including aircraft operated by our regional carriers, we leased 122 aircraft, of which 20 were under finance leases and 102 were operating leases.

Defined Benefit Pension Plans. We sponsor defined benefit pension plans for eligible employees and retirees. These plans are generally closed to new entrants and frozen for future benefit accruals. Our funding obligations for qualified defined benefit plans are governed by the Employee Retirement Income Security Act and any additional applicable legislation. Under current legislation, any required funding would be amortized over a rolling 15-year period and calculated using a discount rate of no less than 4.75% through 2030.

Our executive leadership team, the Delta Leadership Committee (DLC), is our CODM. The DLC regularly reviews information for our two operating segments: our airline segment and our refinery segment. The DLC uses operating income to evaluate segment performance. The DLC is involved in determining and reviewing projected operating income as part of the annual plan process. Throughout the year, the DLC considers forecast to actual results and variances on a monthly and quarterly basis to allocate resources for the airline segment's fleet and network and to optimize the refinery segment's operations. The DLC also considers this information in strategic decisions related to capital allocations, including investments in fleet, ground, information technology and refinery assets, route and network development, and human capital. Airline Segment Our airline segment is managed as a single business unit that provides scheduled air transportation for passengers and cargo throughout the U.S. and around the world and includes our loyalty program, as well as other ancillary businesses.
