Marathon Petroleum Posts Higher Revenue, Operating Income, Net Income, and Diluted EPS Versus Prior Year on Both the Quarter and Six-Month Windows

Bottom line

- Marathon Petroleum Corporation, filing as Marathon Petroleum Corp under ticker MPC, posted higher results across every reported profitability line — earnings per share, net income attributable to the parent, and operating income — on the three-month period and on the six-month year-to-date window versus the prior-year comparative. Revenue also moved in the authorized direction, rising on both the quarter and the half-year view against the same prior-year comparables. The bottom line stayed in profit territory in each frame, and diluted earnings per share likewise held above the prior period on both windows. - For the three-month reporting period the three months ended June 30, 2026, revenue from contracts with customers was $51,994,000,000 USD versus the prior-year comparative $33,799,000,000 USD, operating income was $7,322,000,000 USD versus the prior-year comparative $2,197,000,000 USD, net income attributable to the parent was $5,138,000,000 USD versus the prior-year comparative $1,216,000,000 USD, and diluted earnings per share was $17.73 per diluted share USD/SHARES versus the prior-year comparative $3.96 per diluted share USD/SHARES. - For the six-month year-to-date period the six months ended June 30, 2026, revenue from contracts with customers was $86,194,000,000 USD versus the prior-year comparative $65,316,000,000 USD, operating income was $8,726,000,000 USD versus the prior-year comparative $2,884,000,000 USD, net income attributable to the parent was $5,649,000,000 USD versus the prior-year comparative $1,142,000,000 USD, and diluted earnings per share was $19.30 per diluted share USD/SHARES versus the prior-year comparative $3.68 per diluted share USD/SHARES. - The filing evidence does not attribute this change to any single cause.

- Management framed the interim filing under 10-Q for fiscal period period-ended-2026-06-30 as unaudited but stated that the figures reflect all normal, recurring adjustments necessary for a fair statement of the results. Management identified the business as a leading, integrated downstream and midstream energy company headquartered in Findlay, Ohio, with midstream operations run primarily through MPLX (a consolidated subsidiary) and an additional line producing and marketing renewable diesel in the United States. Management noted that the three and six months ended June (omitted) are not necessarily indicative of full-year results. Management also flagged an ASU on Environmental Credits and Environmental Credit Obligations that is effective for fiscal years beginning after a date referenced in the filing and said it is currently evaluating the impact on consolidated financial statements and disclosures.

- The authorized direction across all four reported dimensions — revenue, operating income, net income, and diluted EPS — was uniformly higher on both the quarter and the half-year windows, and the profit-to-profit transition was preserved on every line. Within the four dimensions named here, no segment-level detail is disclosed; refining, midstream via MPLX, and renewable diesel results are not broken out in this section's quoted scope. Per Note 3, additional information on MPLX is available, and per Note 9, additional information about the company's operations is available.

- No peer or industry comparison is included in the filing evidence; the filing shows only MPC's own prior-year comparables. - No segment-level operating income, revenue, or net income split is disclosed within the four dimensions covered by this section.

UNKNOWN: - The specific cause of the higher revenue, operating income, net income, and diluted EPS results versus the prior year is not attributed in the filing evidence. - Any quarter-over-quarter movement (within the current fiscal year) is outside the scope of the authorized comparisons for this section and is therefore not asserted here.

FILING IDENTITY AND SOURCE SCOPE: - Source: 10-Q filed by Marathon Petroleum Corp (MPC), CIK 0001510295, for fiscal period period-ended-2026-06-30, accession 0001510295-26-000061. The scope of this section is the income-statement line items disclosed in the consolidated statements of income for the three and six months ended June (omitted), together with the prior-year comparables for the same windows, as carried in the unaudited interim consolidated financial statements and accompanying notes referenced via Note 7, Note 3, and Note 9.

Financial performance

- Marathon Petroleum, reporting under 10-Q for period-ended-2026-06-30 (accession 0001510295-26-000061), discloses top-line and bottom-line figures on both the three-month window and the six-month year-to-date window. Revenue from Contract with Customer, Excluding Assessed Tax was $51,994,000,000 for the three months ended June the three months ended June 30, 2026 and $86,194,000,000 for the six months ended June the six months ended June 30, 2026. The matching prior-year comparatives were $33,799,000,000 for the three-month window and $65,316,000,000 for the six-month window.

On a year-over-year basis, the authorized comparison is revenue higher than the prior period for both the quarter and the year-to-date view, with the period-over-period transition remaining in positive territory. - Operating Income (Loss) was $7,322,000,000 for the three-month reporting period and $8,726,000,000 for the six-month year-to-date period. The prior-year comparatives were $2,197,000,000 and $2,884,000,000.

The authorized year-over-year comparison describes operating income higher than the prior period for both windows, with a profit-to-profit transition in each case. The quarter-over-quarter framing is not supported by an authorized comparison in the catalog, so no QOQ direction is asserted here. - Net Income (Loss) Attributable to Parent was $5,138,000,000 for the quarter and $5,649,000,000 for the six months ended June, compared with $1,216,000,000 and $1,142,000,000 in the prior year.

The authorized direction is higher than the prior period for both the quarter and the year-to-date period, with a profit-to-profit transition in each case. 68 per diluted share in the prior year, following the same authorized higher-than-the-prior-period pattern with a profit-to-profit transition. - Management frames these interim statements as unaudited but reflective of all normal, recurring adjustments necessary for a fair presentation, prepared under SEC interim-period rules and read alongside the audited annual report referenced in Note 9.

The consolidation perimeter continues to include majority-owned, controlled subsidiaries such as MPLX, with noncontrolling interest recorded for the public holders of MPLX units and equity-method accounting applied to entities of significant influence but not control. Segment reporting for Marathon Petroleum Corp captures intersegment activity among Refining & Marketing, Renewable Diesel, and Midstream, with related-party detail carried in Note 4. - Accounting context includes several standards not yet adopted by Marathon Petroleum Corp.

The recently issued ASU on environmental credits and environmental credit obligations, the ASU modernizing internal-use software accounting, and the ASU on expense disaggregation disclosures are each described as currently being evaluated; the renewable-diesel business noted in the source narrative is the segment most exposed to the environmental-credits standard once effective. The filing evidence does not attribute this change to any single cause. - Guidance expectations are not stated in numerical form in the quoted evidence; the filing characterizes the interim results as not necessarily indicative of the full-year outcome, leaving forward-period direction qualitative rather than quantified.

The filing evidence contains no peer or industry comparison.

Operating drivers and segments

The filing describes Marathon Petroleum Corporation as a leading, integrated, downstream and midstream energy company headquartered in Findlay, Ohio, selling refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market and to independent entrepreneurs who operate branded outlets, and supplying transportation fuel to consumers through direct dealer locations under long-term supply contracts. Midstream activity is presented as conducted primarily through MPLX, which owns and operates crude oil and light-product transportation and logistics infrastructure as well as gathering, processing and fractionation assets, with MPC holding the general partner and a majority limited partner interest in MPLX. Renewable diesel production and marketing in the United States is also noted, and the cited note offers further detail on MPLX while the cited note provides additional information about operations.

Reported segment scope has shifted during the period: MPC's equity-method investment in TAMH was previously reported in the Refining & Marketing segment, and prior to a sale the Rockies operations were included in the Midstream segment. The BANGL Acquisition moved the acquired business into the Midstream segment within the consolidated financial results, with MPLX now owning a majority percentage of BANGL, and the purchase price allocation produced goodwill reported in the Midstream segment, partly deductible by MPLX for tax purposes. Intersegment transactions between corporate and the Midstream segment are eliminated in consolidation.

Operating income for the three-month reporting period was $7,322,000,000 USD, higher than the prior-year comparative of $2,197,000,000 USD, and the six-month year-to-date operating income reached $8,726,000,000 USD, higher than the prior-year comparative of $2,884,000,000 USD, with both windows showing a profit. Revenue from contracts with customers, excluding assessed tax, was $51,994,000,000 USD for the three-month reporting period, higher than the prior-year comparative of $33,799,000,000 USD, while the six-month year-to-date figure of $86,194,000,000 USD was higher than the prior-year comparative of $65,316,000,000 USD. Segment-level financial decomposition beyond these top-line figures is not directly shown in the quoted material.

Management's commentary emphasizes organizational reshaping and accounting change rather than per-barrel or unit-economics drivers. The narrative ties reported-segment commentary to the BANGL Acquisition, the repositioning of TAMH out of Refining & Marketing, the prior inclusion of Rockies operations in Midstream, and the goodwill recognized in the Midstream segment from the purchase price allocation. Two pending accounting standards are also referenced: an ASU modernizing internal-use software capitalization under the cited ASC subtopic, and an ASU requiring more detailed disaggregation of specified expense categories on the face of the income statement, both of which are framed as prospective policy matters rather than current-period drivers.

Independent reading: the year-over-year direction on both revenue and operating income is favorable across the quarter and the six-month year-to-date view, but the quoted evidence does not separate which segment — Refining & Marketing versus Midstream — accounted for the change. The filing evidence does not attribute this change to any single cause. The filing evidence contains no peer or industry comparison. The omission patterns in the purchase price allocation leave several balance figures unavailable for restatement here, so goodwill and acquired-asset totals are noted as presented rather than paraphrased.

Cash flow and capital

- Operating cash generation expanded on a year-over-year basis, with Net Cash Provided by (Used in) Operating Activities for the six-month year-to-date period of the six months ended June 30, 2026 at $11,448,000,000 USD, up from $2,575,000,000 USD in the prior-year comparative window of the six months ended June 30, 2025. - Investing activity remained a use of cash, with Net Cash Provided by (Used in) Investing Activities of -$2,441,000,000 USD over the six months ended June 30, 2026, compared with -$1,897,000,000 USD over the six months ended June 30, 2025.

- Financing activity was also a net use of cash in both years, with Net Cash Provided by (Used in) Financing Activities of -$4,912,000,000 USD for the six months ended June 30, 2026, against -$2,215,000,000 USD for the six months ended June 30, 2025. - Reported facts: management explains the investing line through the capital program, including Payments to Acquire Property, Plant, and Equipment of $2,099,000,000 USD for the six months ended June 30, 2026 versus $1,358,000,000 USD for the six months ended June 30, 2025, and through completed portfolio moves such as MPLX's Northwind Delaware Holdings acquisition and the BANGL Acquisition, both consolidated within the Midstream segment and disclosed across the cited notes that include Note 3, Note 9, and Note 14.

- Management explanation: within the financing outflows, the return-of-capital mix is described through Payments for Repurchase of Common Stock of $3,283,000,000 USD for the six months ended June 30, 2026 versus $1,837,000,000 USD for the six months ended June 30, 2025, alongside Payments of Ordinary Dividends, Common Stock of $585,000,000 USD for the six months ended June 30, 2026 versus $564,000,000 USD for the six months ended June 30, 2025. - Analyst inference: the operating-versus-financing spread suggests internally generated cash continued to absorb both a heavier capital program and a heavier shareholder-return load than the prior period, leaving financing cash usage wider even as operating cash rose.

- Counter-evidence: the prior-period financing line was also a use of cash, so the directional deterioration sits inside an outflow rather than a swing from inflow to outflow, which limits how much margin a capital-allocation squeeze can be inferred. - Unknowns: a single attributable cause for the larger financing outflow is not pinned down in the cited evidence. The filing evidence does not attribute this change to any single cause.

- Balance sheet posture at the balance sheet date of June 30, 2026 is shown through Cash and Cash Equivalents, at Carrying Value of $7,768,000,000 USD and Accounts Payable, Current of $19,227,000,000 USD, providing the closing liquidity and short-term trade-payable snapshot against which the cash-flow story above is read. ](/insights/finance/aes-corp-interim-filing-shows-higher-revenue-and-a-loss-to-profit-swing-on-net/).

Peer and historical context

- The filing presents MPC's three-month and six-month year-to-date lines in period-ended-2026-06-30 under accession 0001510295-26-000061, and the only authorized cross-period arrows in this section's ledger are year-over-year, so any peer read is structurally absent from the evidence set rather than implied by it. - Because every authorized comparison is internal-to-internal (this quarter against the prior-year quarter, and the half-year window against the same window a year earlier), the cleanest framing is to walk the four reported dimensions — revenue, operating income, net income, and operating cash flow — in that sequence and then close with what the filing does and does not let a reader conclude.

- The same filing that authorizes the year-over-year arrows also discloses two sizable business combinations — the Whiptail Midstream acquisition and the BANGL step-up to full ownership — whose purchase accounting moved intangible assets, goodwill, and previously held equity-method investments into the Midstream segment, so a clean prior-period match across the half-year boundary cannot be assumed without further reconciliation.

<prose> Marathon Petroleum's period-ended-2026-06-30 report, filed as 10-Q under accession 0001510295-26-000061, frames its year-over-year story on two reporting windows: a three-month period ending in the quarter closed this period, and a six-month year-to-date period covering the first half of the fiscal year. Each of the four headline measures — revenue from contracts with customers, operating income, net income attributable to the parent, and net cash provided by operating activities — is presented against the matching window of the prior year, and the authorized direction for every one of those arrows is the same: higher than the prior period. That uniformly upward set is the strongest comparative signal the filing supports on its own.

The half-year comparisons are the broadest lens. Revenue from contracts with customers moved from $65,316,000,000 in the prior-year window to $86,194,000,000 in the six months ended June 30, 2026, while operating income moved from $2,884,000,000 to $8,726,000,000, and net income attributable to the parent moved from $1,142,000,000 to $5,649,000,000. Operating cash flow, drawn from the consolidated cash flow statement rather than the income statement, moved from $2,575,000,000 to $11,448,000,000 over the same the six months ended June 30, 2026 window, with the authorized direction again reading as higher than the prior period. Earnings per share, diluted, is also reported as higher on both the half-year and the quarter views, with the current and prior periods both in profit — a profit-to-profit transition that the filing itself flags.

The three-month window tells a similar story at a narrower scope. Revenue moved from $33,799,000,000 to $51,994,000,000 across the three months ended June 30, 2026 versus the three months ended June 30, 2025, operating income moved from $2,197,000,000 to $7,322,000,000, and net income attributable to the parent moved from $1,216,000,000 to $5,138,000,000 — every arrow again reading higher than the prior period and every pair showing a profit-to-profit transition.

What the filing does not do is equally important for this section. No peer or industry comparison is offered: there is no benchmark against another refiner, no index-relative read, and no segment-versus-segment ranking versus MPLX peers. The filing evidence therefore does not attribute the year-over-year movement to any single cause, and the only honest read available is that the directions are uniformly upward across revenue, operating income, net income, and operating cash flow on both windows. Readers looking for a peer anchor can turn to related filings on the platform, such as the AES Corp interim filing showing higher revenue and a loss-to-profit swing on net income and diluted EPS for both the quarter and the six-month year-to-date period, while capital and dividend outflows also stepped up, which sits in the same interim-filing universe but covers a different issuer and cannot be used as a direct benchmark for MPC. The filing evidence does not attribute this change to any single cause.

Scenario analysis

In the base case, Marathon Petroleum Corporation's reported results represent the continuation of the directional pattern visible in this filing. Revenue from contracts with customers, excluding assessed tax, is reported at $51,994,000,000 for the three-month period of the three months ended June 30, 2026, compared with $33,799,000,000 for the three months ended June 30, 2025, and at $86,194,000,000 for the six months ended June 30, 2026, compared with $65,316,000,000 for the six months ended June 30, 2025. Net income attributable to the parent is reported at $5,138,000,000 for the three months ended June 30, 2026, against $1,216,000,000 for the three months ended June 30, 2025, and at $5,649,000,000 for the six months ended June 30, 2026, against $1,142,000,000 for the six months ended June 30, 2025. Within this base view, both revenue and net income remain positive on both reporting windows, consistent with the authorized profit-to-profit transition recorded in the reported comparisons for the quarter and the half year. Management's commentary, drawn from Item 1A and Note 3, frames the period around the completion of the BANGL Acquisition by MPLX, the Whiptail Midstream Acquisition, and the prior Rockies operations contribution now reclassified into the Midstream segment, with the equity method investment in TAMH previously reported in the Refining & Marketing segment. The filing evidence does not attribute this change to any single cause.

In an upside scenario, the directional momentum already disclosed would extend into the second half without reversal. Revenue of $51,994,000,000 for the three months ended June 30, 2026 and $86,194,000,000 for the six months ended June 30, 2026 would continue to print higher than the prior-year comparative lines of $33,799,000,000 and $65,316,000,000, respectively. Net income attributable to the parent of $5,138,000,000 for the three months ended June 30, 2026 and $5,649,000,000 for the six months ended June 30, 2026 would likewise remain above the prior-year bases of $1,216,000,000 and $1,142,000,000. The upside read leans on the integration narrative presented in Note 9, where MPLX's full ownership of a strategically located NGL transport asset is described as advancing the wellhead-to-water strategy and further integrating midstream infrastructure between the Permian and the Gulf Coast, together with the San Juan basin gathering systems added through the Whiptail Midstream Acquisition. The midstream consolidation detail in Note 14 provides further reference for how the contingent consideration and previously held equity interest were measured. The filing evidence does not attribute this change to any single cause.

In a downside scenario, the same reported lines would lose their year-over-year improvement. Revenue would either compress back toward $33,799,000,000 for the three months ended June 30, 2025 and $65,316,000,000 for the six months ended June 30, 2025, or fall below those bases, reversing the higher direction recorded for $51,994,000,000 against $33,799,000,000 and for $86,194,000,000 against $65,316,000,000. Net income attributable to the parent would similarly retreat from $5,138,000,000 and $5,649,000,000 toward or below $1,216,000,000 and $1,142,000,000. The accounting mechanics disclosed in Note 14, including the contingent consideration and the remeasurement of the previously held equity method investment in TAMH at fair value, and the variable interest entity presentation in Note 7 that records a noncontrolling interest for MPLX's public unitholders, remain the structural anchors of this view, while the BANGL Acquisition's goodwill recognised by the Midstream segment is highlighted by management as supporting integration rather than as a standalone growth driver. The filing evidence contains no peer or industry comparison.

Risks and what to watch

- Reported facts: Marathon Petroleum Corp's 10-Q for period-ended-2026-06-30 (accession 0001510295-26-000061, ticker MPC) frames this section around the three- and six-month windows. Top-line Revenue from Contract with Customer, Excluding Assessed Tax for the quarter came in at $51,994,000,000 USD for the three months ended June 30, 2026, against $33,799,000,000 USD for the three months ended June 30, 2025, with the year-to-date view at $86,194,000,000 USD for the six months ended June 30, 2026 versus $65,316,000,000 USD for the six months ended June 30, 2025.

Net Income (Loss) Attributable to Parent ran to $5,138,000,000 USD for the three months ended June 30, 2026 against $1,216,000,000 USD for the three months ended June 30, 2025, and $5,649,000,000 USD for the six months ended June 30, 2026 against $1,142,000,000 USD for the six months ended June 30, 2025. The earnings-per-share, operating-income, and cash-flow comparisons authorized for this filing all show a profit-to-profit year-over-year direction with higher values for revenue and earnings, alongside larger investing- and financing-related outflows.

- Management explanations: The narrative in Note 3 describes the BANGL and Whiptail Midstream acquisitions by MPLX, framed as advancing a "wellhead-to-water strategy" by integrating NGL transport and San Juan gathering systems into the Midstream segment. Note 9 carries the basis-of-presentation language, Note 4 covers related-party sales and purchases of utilities, transportation services and renewable diesel from equity affiliates, Note 7 describes the basic earnings-per-share computation that allocates income to participating securities, Note 14 discusses fair-value measurement inputs, and Note 22 addresses the equity / preferred-stock disclosure.

Item 1 flags legal proceedings, Item 1A flags risk factors, Item 3 flags market-risk disclosures, Item 4 flags controls and procedures, Item 2 flags unregistered equity sales and use of proceeds, Item 5 flags other information, Item 6 flags exhibits and signatures. - Analyst inference: The filing evidence does not attribute this change to any single cause. - Counter-evidence: The filing evidence contains no peer or industry comparison.

Even so, the headline P&L and revenue lines move in the same direction as the year-ago period, and authorized operating-income and diluted-EPS year-over-year comparisons also remain profit-to-profit, which cuts against a narrative of deterioration on those dimensions. Readers can place the reported quarter in a broader cross-section using CMS Energy Reports Softer Bottom Line Against Higher Contract Revenue in period-ended-2026-06-30 10-Q Filing.

- Unknowns: The cited note language treats pro forma revenue and earnings from the BANGL Acquisition as not material for disclosure, which leaves the precise contribution of recent MPLX transactions to the six months ended June 30, 2026 results undisclosed in this filing. - Metrics to watch next period: quarterly and year-to-date Revenue from Contract with Customer, Net Income (Loss) Attributable to Parent, operating-income direction, investing- and financing-related cash flow, and any update to MPLX-related balances and guarantee disclosures in the next interim filing.
