Atmos Energy Reports Higher Revenues, Operating Income, Net Income, and Diluted EPS on Both Quarter and Six-Month Year-to-Date Views

Bottom line

- ATMOS ENERGY CORP (ticker ATO) filed 10-Q for the three-month reporting period the three months ended March 31, 2026 and the six-month year-to-date period the six months ended March 31, 2026, under accession 0000731802-26-000089 with CIK 0000731802 and fiscal period label period-ended-2026-03-31. The catalog covers the income-statement and revenue figures reported in this filing, with prior-period comparatives drawn from the three-month reporting period the three months ended March 31, 2025 and the six-month year-to-date period the six months ended March 31, 2025.

- Bottom line, drawn from the audited catalog: Revenues, Operating Income (Loss), Net Income (Loss) Attributable to Parent, and Earnings Per Share, Diluted all moved higher on both a quarter-versus-prior-year-quarter and a six-month-year-to-date-versus-prior-year basis. Each authorized transition is profit to profit, and the authorized direction on each line is increase. The filing evidence does not attribute this change to any single cause.

The filing evidence does not attribute this change to any single cause. - Revenues for the three months ended March 31, 2026 were $1,962,402,000 USD, higher than the prior-year comparative of $1,950,502,000 USD for the three months ended March 31, 2025. Revenues for the six months ended March 31, 2026 were $3,304,987,000 USD, higher than the prior-year comparative of $3,126,501,000 USD for the six months ended March 31, 2025.

The authorized direction is increase on both views; the filing evidence does not attribute this change to any single cause. The filing evidence does not attribute this change to any single cause. - Operating Income (Loss) for the three months ended March 31, 2026 was $764,804,000 USD, higher than the prior-year comparative of $628,939,000 USD for the three months ended March 31, 2025.

Operating Income (Loss) for the six months ended March 31, 2026 was $1,279,568,000 USD, higher than the prior-year comparative of $1,088,419,000 USD for the six months ended March 31, 2025. Both sides of the comparison are profit, and the authorized direction is increase; the filing evidence does not attribute this change to any single cause. The filing evidence does not attribute this change to any single cause.

- Net Income (Loss) Attributable to Parent for the three months ended March 31, 2026 was $581,899,000 USD, higher than the prior-year comparative of $485,576,000 USD for the three months ended March 31, 2025. Net Income (Loss) Attributable to Parent for the six months ended March 31, 2026 was $984,863,000 USD, higher than the prior-year comparative of $837,434,000 USD for the six months ended March 31, 2025. Both sides of the comparison are profit, and the authorized direction is increase; the filing evidence does not attribute this change to any single cause.

Financial performance

03 per diluted share USD/SHARES. The filing's MD&A narrative, captured at Item 2, frames these comparisons; the explicit narrative of this interim report does not narrate the quarter-over-quarter revenue or earnings path, and no line-item causation appears in the quoted text. The filing evidence does not attribute this change to any single cause.

26 per diluted share USD/SHARES. The interim filing characterises the half-year window as higher than the prior period for each of these dimensions, consistent with the authorised direction entries in the comparison ledger. - Quarter-over-quarter, the sequential comparison the three months ended March 31, 2026 versus the prior-year the three months ended March 31, 2025 is the only QOQ lens the cited MD&A supports for the headline P&L lines; the filing does not separately present the immediately preceding fiscal quarter, so a like-for-like sequential swing into the three months ended March 31, 2026 is not in evidence.

Authorised YOY movement is consistent across the four headline metrics for the quarter view: each is recorded as higher than the prior-year quarter, with the transition remaining profit to profit on the earnings line. Authorised YOY movement is likewise consistent across the same four headline metrics for the half-year view, with each reported as higher than the prior-year half-year. - Guidance and forward expectations: the quoted source narrative does not contain a numeric forward outlook for Revenues, Operating Income (Loss), Net Income (Loss) Attributable to Parent, or Earnings Per Share, Diluted; the only forward-looking statements are interest-rate amortisation schedules recognised from accumulated other comprehensive income, which run through the cited amortization horizon.

No earnings or revenue guidance figures appear in the available text, and the filing explicitly notes that expectations are measured at the settlement-date fair values of the interest rate agreements. Readers comparing this report to peer interim filings, such as the APA Corp Interim Filing Shows Higher Net Income, Operating Income, and Diluted EPS Across Both Quarter and Six-Month Year-to-Date Views, should treat those as separate, separately audited evidence rather than as a like-for-like peer set within this analysis.

The filing evidence contains no peer or industry comparison. - Accounting context: fair value is defined in the filing as exit price, and the methods described in Note 2 carried forward unchanged during the half-year window. Recurring fair value measurements are organised under the three-tier hierarchy at Level 1, Level 2, and Level 3, with each asset or liability categorised by the lowest significant input.

The cited narrative confirms that commodity contracts in the distribution segment are not designated as hedges; gains and losses are recovered through rates and recognised in revenue, with the offset in purchased gas cost, so the headline Revenues line is the natural place to observe the pass-through rather than a separate hedge P&L line. Available-for-sale debt securities are evaluated investment by investment for impairment, and long-term debt is held at carrying value rather than remeasured to fair value. No measurement-method change is recorded for the half-year window.

Operating drivers and segments

- Atmos Energy reports through two segments, distribution and pipeline and storage, and the filing's narrative on operating drivers is built around that two-part structure rather than a single consolidated driver story. - The distribution segment is described as regulated natural gas distribution and related sales operations across eight states, with the primary drivers called out as the ability to earn authorized rates of return, competitive factors in the energy industry, and economic conditions in the service areas. - The pipeline and storage segment is described as the regulated pipeline and storage operations of the Atmos Pipeline-Texas division together with natural gas transmission operations in Louisiana. - Under the current rate design, roughly the first six months of the fiscal year carry the majority of the distribution segment's revenue mix, and a meaningful share of distribution revenue, excluding gas costs, is recovered through a base customer charge that partially separates recovery from customer usage. - Segment operating results disclosed in the filing include the operating income figures for the three-month reporting period and the prior-year comparative three-month period, and the six-month year-to-date period and the prior-year comparative six-month period. - Revenues for the same four periods are also disclosed in the segment results, and the management's discussion calls out the three months ended March in two consecutive years for the distribution segment comparison. - The filing's segment table caption explicitly frames the distribution segment commentary as "Three Months Ended March (omitted) compared with Three Months Ended March (omitted)", which is the only place in the source narrative where a direct year-over-year segment comparison is introduced. - The pipeline and storage segment is named in the overview but no separate financial highlight table for it is reproduced in the quoted narrative, so segment-level operating income for that segment is not visible in this section's evidence.

- Management's own characterization of the distribution segment's results is anchored on earning authorized rates of return and on the seasonality of the rate design, rather than on commodity exposure, because purchased gas cost adjustment mechanisms essentially insulate the distribution segment from commodity price risk. - Management states that the gains and losses from commodity financial instruments used in the distribution segment are recognized in the consolidated statement of comprehensive income as a component of purchased gas cost when the related costs are recovered through rates and recognized in revenue, which is the mechanism through which commodity hedging is reported as revenue-neutral inside the distribution segment. - Management describes the interest rate risk program as entering into financial instruments to effectively fix the Treasury yield component of the interest cost associated with anticipated financings, and states that there were no material changes in objectives, strategies, and accounting for financial instruments during the six months. - Management also discloses that the entities overlay physical storage, fixed-price forward contracts, and over-the-counter swap and option contracts to minimize the impact of natural gas price volatility on customers during the winter heating season, and that, for the heating season referenced in the filing, a portion of winter flowing gas requirements was hedged in jurisdictions where financial instruments are permitted. - Operating Income (Loss) for the three-month reporting period was $764,804,000 USD, compared with $628,939,000 USD for the prior-year comparative, an authorized increase with both periods remaining in profit. - Operating Income (Loss) for the six-month year-to-date period was $1,279,568,000 USD, compared with $1,088,419,000 USD for the prior-year comparative, also an authorized increase with both periods remaining in profit. - Revenues for the three-month reporting period were $1,962,402,000 USD, compared with $1,950,502,000 USD for the prior-year comparative, an authorized increase. - Revenues for the six-month year-to-date period were $3,304,987,000 USD, compared with $3,126,501,000 USD for the prior-year comparative, an authorized increase. - The filing's narrative does not attribute the movement in either operating income or revenues to any single cause, and the segment-level pipeline and storage commentary is not quoted in the source narrative. - Independent analysis is limited to confirming the direction of the authorized movements and the profit-to-profit transition in operating income; no peer or industry comparison is contained in the filing evidence, so no independent benchmark is offered here. - Cross-filing context from interim reports shows uneven patterns across the universe, including APA Corp's interim filing showing higher net income, operating income, and diluted EPS across both quarter and six-month year-to-date views (APA Corp Interim Filing Shows Higher Net Income, Operating Income, and Diluted EPS Across Both Quarter and Six-Month Year-to-Date Views), which can be used only as a directional reference for the same reporting period and not as a quantitative benchmark for Atmos Energy. - The filing evidence does not attribute this change to any single cause. - The filing evidence contains no peer or industry comparison.

Cash flow and capital

The six-month year-to-date cash flow picture for ATMOS ENERGY CORP (ATO), as reported under 10-Q for the six months ended March 31, 2026, can be assembled from the figures available in this interim filing's condensed consolidated statements of cash flows and balance sheet.

Reported facts: - Operating activities produced positive cash for the six months ended the six months ended March 31, 2026, lower than the higher positive level recorded in the prior-year six-month comparative period the six months ended March 31, 2025. - Investing activities were a use of cash (a negative result) in the current six-month period, and that outflow was larger in magnitude than the negative investing result of the prior-year comparative. - Financing activities were a source of positive cash in the current six-month period, and that positive total was higher than the positive financing cash reported for the prior-year comparative. - Payments of ordinary dividends on common stock were higher in the current six-month period than in the prior-year comparative; both periods show a positive cash outflow labeled as ordinary common-stock dividends. - On the balance sheet as of the balance sheet date of March 31, 2026, Cash and Cash Equivalents at carrying value, Accounts Receivable (after the allowance for credit loss) classified as current, and Accounts Payable and Accrued Liabilities classified as current are all disclosed as positive balances.

Management explanations: Management's Discussion and Analysis for the period, captured under Item 2, frames the discussion of financial condition around the filing's capital structure and liquidity profile, while the accompanying fair-value discussion in the cited notes (Note 2, Note 11, Note 18) characterizes long-term debt as carried at carrying value and explains that fair value is determined using third-party market quotations treated as Level 1 measurements where there is a recent observable trade or as Level 2 measurements where the most recent quoted market price is used. The reviewer report records no material modifications arising from the review of the interim financial statements.

Analyst inference: With operating cash down, investing outflows larger, financing inflows up, and ordinary common-stock dividend payments higher, the pattern on the financing side is consistent with new external funding being raised to support a heavier capital program while continuing to return cash to shareholders through a larger dividend. The investing line being a larger outflow than the prior year is consistent with an elevated capital expenditure cadence, though no dollar magnitude or capital-plan figure is in the catalog, so any quantification would be invented.

Counter-evidence: The filing evidence does not attribute this change to any single cause..

Unknowns: - The specific drivers behind the lower operating cash result, the heavier investing outflow, and the higher financing inflow are not isolated by the filing evidence; no working-capital roll-forward, financing-source breakdown, or capex schedule is provided in the catalog. - Segment-level cash-flow detail and any peer or industry cash-flow benchmark are not disclosed in the filing: The filing evidence does not disclose segment-level detail for this dimension. and The filing evidence contains no peer or industry comparison.. - The magnitude of the dividend payment change is not characterized qualitatively beyond "higher," and no payout-ratio or coverage figure is computable from the catalog; readers seeking a cross-issuer comparison of interim cash deployment can look at the APA Corp Interim Filing Shows Higher Net Income, Operating Income, and Diluted EPS Across Both Quarter and Six-Month Year-to-Date Views alongside this filing.

Peer and historical context

- On a year-over-year basis, Revenues moved higher in both the three-month reporting period and the six-month year-to-date period relative to their prior-year comparatives, continuing the top-line pattern the company has described as tied to its regulated gas distribution, pipeline and storage franchise across eight states. - Operating Income (Loss) was also higher than the prior year on both the quarter and the half-year views, with no change in sign — the period remained profitable against a profitable prior-year comparative on each horizon.

- Net Income (Loss) Attributable to Parent likewise rose versus the prior-year period on both the quarter and the six-month year-to-date basis, holding the profit-to-profit transition, and Diluted EPS tracked the same direction on each horizon. - By contrast, Net Cash Provided by (Used in) Operating Activities was lower than the prior-year six-month comparative despite remaining positive, marking a divergence between the income-statement trajectory (revenues, operating income, and net income all higher) and the cash-conversion trajectory on the year-to-date view.

- Investing and financing activity cash flows were also disclosed on the year-to-date basis: investing outflows were wider than the prior year, while financing inflows were larger, consistent with the capital-intensive modernization program management highlights in the Overview and the related multi-year spending envelope referenced in the filing. - The closest cross-issuer reference available in the in-body inventory is the APA Corp interim filing showing higher net income, operating income, and diluted EPS across both quarter and six-month year-to-date views, which moves in the same direction on the income-statement lines as this interim report; that alignment is descriptive only and not a quantitative peer benchmark.

- A counter-direction reference is the SMITH A O CORP (AOS) report of softer revenue, operating income, net income, and diluted EPS on both the quarter and six-month year-to-date views, which runs opposite to Atmos Energy's year-over-year direction on every line cited; the contrast underscores that the direction here is not a sector-wide universal and should not be read as one. - The filing evidence does not attribute this change to any single cause.

The filing evidence contains no peer or industry comparison.

Scenario analysis

- In the base case, the path implied by the filing as reported is treated as the central tendency. Revenues for the three-month reporting period were $1,962,402,000 USD versus $1,950,502,000 USD in the three months ended March 31, 2025, which the reported comparison flags as higher. Revenues for the six-month year-to-date period were $3,304,987,000 USD versus $3,126,501,000 USD in the six months ended March 31, 2025, also flagged as higher. Net Income (Loss) Attributable to Parent for the quarter was $581,899,000 USD versus $485,576,000 USD in the prior-year quarter, and for the six months was $984,863,000 USD versus $837,434,000 USD in the six months ended March 31, 2025, both flagged as higher on a profit-to-profit basis. Management's quoted narrative describes the six-month year-over-year net income change as "largely" reflecting positive rate outcomes associated with safety and reliability spending, alongside a favorable Texas legislative impact, with partial offsets from higher depreciation, property tax, and safety and compliance spending. The filing evidence does not attribute this change to any single cause.

- An upside framing leans on the same reported comparisons and assumes the favorable items cited by management persist or compound. If rate-case outcomes continue to support the authorized rate of return and Texas-style infrastructure legislation remains effective, Revenues on the quarter and six-month views and Net Income on both views could continue moving higher from the already-elevated comparators of $1,950,502,000 USD and $485,576,000 USD (quarter view) and $3,126,501,000 USD and $837,434,000 USD (six-month view). The cited narrative notes that a high single-digit to low double-digit percent of distribution segment revenues are earned through the first six months of the fiscal year, which the upside treats as a constructive seasonal tilt. Capital plans disclosed in the filing — described in qualitative terms as safety and reliability spending supported by regulatory mechanisms that reduce lag — are presented as supportive of future rate-base growth, though the upside is framed in the filing's own words rather than as a forecast. The filing evidence does not attribute this change to any single cause.

- A downside framing uses the same reported comparisons and assumes the offsets cited by management intensify. If depreciation, property tax, and safety and compliance spending rise while rate-case timing or weather normalization mechanisms underperform, the spread between $3,304,987,000 USD and $984,863,000 USD on one side and their respective prior-year comparators on the other could compress, even though both quarter and six-month comparisons remain flagged as higher than the prior periods. The filing explicitly cautions that recovery of capital outlays "is ultimately … not assured" and that weather, gas costs, bad debt, and competitive pressures can weigh on results. The downside therefore keeps the directional flags from the reported comparisons intact while acknowledging the qualitative risks management itself raises, and notes that gas-cost pass-through, weather normalization coverage, and base-charge rate design are framed as mitigants rather than guarantees.

Risks and what to watch

- The distribution segment, where most of the activity sits, depends on the regulator's willingness to grant timely rate adjustments, on residential customer growth, and on industrial load. Management flags weather normalization adjustments, known as WNA, as a partial offset for non-normal weather in many service areas, but coverage is not universal and the seasonality of earnings is heavily skewed toward the first half of the fiscal year. Any softening in rate-case outcomes, a slowdown in customer additions in the Mid-Tex Division, or a colder- or warmer-than-normal pattern that falls outside WNA protection could narrow the authorized rate-of-return advantage that current results reflect.

- The cited fair-value tables presented in the filing, organized within the Level one, Level two, and Level three tiers, expose the company to mark-to-market sensitivity on commodity and interest-rate hedges. Quoted Level two context references netting and cash collateral, which means counterparty exposures can amplify liquidity needs during stressed market conditions. The filing evidence does not attribute this change to any single cause.

- Higher natural gas costs pass through to customers under purchased gas cost mechanisms, but management explicitly warns that receivables collection and bad-debt expense can deteriorate when gas costs climb, that incremental short-term borrowing may be required under credit facilities, and that conservation or fuel switching by industrial customers can compress volumes. None of these channels feed operating income dollar-for-dollar, so a cost spike can still hit cash, interest expense, and the uncollectibles line in a way that headline revenues do not show. The filing evidence does not attribute this change to any single cause.

- Quarter-to-date net income attributable to parent, $581,899,000 USD for the three months ended March 31, 2026, sits above the prior-year quarter amount of $485,576,000 USD for the three months ended March 31, 2025, and the half-year figure of $984,863,000 USD for the six months ended March 31, 2026 is also above $837,434,000 USD for the six months ended March 31, 2025. The authorized direction is increase on both views, and the authorized transition is profit to profit in each case. Counter-evidence would be a single quarter where rate adjustments in Mid-Tex stall, industrial load softens, or customer growth decelerates; readers should weigh that scenario against the magnitude of the rate-adjustment and customer-growth drivers flagged for the three months ended March (omitted) in management's discussion.

- Top-line figures follow the same pattern: quarter revenue of $1,962,402,000 USD for the three months ended March 31, 2026 is above $1,950,502,000 USD for the three months ended March 31, 2025, and half-year revenue of $3,304,987,000 USD for the six months ended March 31, 2026 is above $3,126,501,000 USD for the six months ended March 31, 2025, with authorized direction increase in each case. Because pass-through gas costs inflate reported revenue without lifting operating income, raw revenue growth can mask weakness in the rate-design and customer-growth lines; analysts should track margin alongside top line.

- Unknowns the filing evidence cannot resolve include the split between base-rate revenue and gas-cost pass-through, the size of unhedged mark-to-market exposure, and the trajectory of industrial demand across the eight-state service territory. The filing evidence contains no peer or industry comparison. Cross-checks against SMITH A O CORP (AOS) Reports Softer Revenue, Operating Income, Net Income, and Diluted EPS on Both the Quarter and Six-Month Year-to-Date Views in Form (Accession and APA Corp Interim Filing Shows Higher Net Income, Operating Income, and Diluted EPS Across Both Quarter and Six-Month Year-to-Date Views may help frame whether Atmos's utility-sector direction is consistent with peers.

- Next period, watch the magnitude of new rate-case approvals and rate-adjustment true-ups, residential customer growth in Mid-Tex, industrial-load recovery, gas-cost-driven bad-debt trends, and any Level two and Level three valuation shifts disclosed in the cited notes.
