Phillips 66 Q2 2026 earnings: Higher refining margins lift net income to $3.8 billion

Phillips 66 (NYSE: PSX) reported Q2 2026 net income attributable to the company of $3.847 billion, up from $877 million in Q2 2025, while diluted EPS rose to $9.55 from $2.15. For the quarter ended June 30, adjusted earnings reached $3.788 billion, with the increase concentrated in Refining and Renewable Fuels; operating cash flow was $7.259 billion, and total debt fell by $6.6 billion during the quarter.

Core financial results

Phillips 66’s bottom-line performance improved substantially from both the prior-year quarter and Q1 2026. GAAP and adjusted earnings were close, indicating that special-item adjustments had a limited net effect relative to total quarterly profit.

The company disclosed year-over-year comparisons for earnings and EPS, while adjusted EBITDA and cash-flow comparisons were provided sequentially.

Adjusted earnings, adjusted EPS, adjusted EBITDA and operating cash flow excluding working capital are non-GAAP measures. Second-quarter adjustments included a gain related to post-closing changes from a previously completed retail asset sale and a legal accrual.

Business and segment performance

Refining generated most of the year-over-year increase in adjusted pre-tax income, while Renewable Fuels moved from a loss to a profit. Chemicals also improved, but Marketing and Specialties remained below its prior-year result despite rebounding from a Q1 loss.

Refining margins drove most of the profit increase

Refining’s realized margin rose to $24.08 per barrel from $10.11 in Q1 2026. Management attributed the improvement primarily to higher market crack spreads and favorable mark-to-market effects. Crude capacity utilization reached 96%, compared with 95% in Q1, while turnaround expense declined to $123 million from $178 million following completed work at the Wood River and Humber refineries.

Investors should note that the year-over-year Refining comparison is not fully like-for-like. Results through September 30, 2025, included Phillips 66’s proportional share of WRB Refining equity earnings; beginning October 1, 2025, the company consolidated 100% of the Borger and Wood River refineries after acquiring the remaining 50% of WRB.

Renewable Fuels returned to profitability

Renewable Fuels improved from a $41 million pre-tax loss in Q1 to a $544 million profit in Q2. The company cited higher regulatory credit pricing, increased renewable-fuel production and favorable mark-to-market effects. Production increased to 53,000 barrels per day from 40,000 in the previous quarter.

Midstream income benefited from higher margins and volumes, partly because the quarter did not repeat Q1’s Winter Storm Fern disruption. NGL fractionation reached a record 1.020 million barrels per day, while NGL pipeline throughput increased to 943,000 barrels per day.

Chemicals benefited from higher margins even as global olefins and polyolefins capacity utilization declined to 91% from 94%. Marketing and Specialties recovered sequentially from a $141 million adjusted loss to a $514 million profit, supported by higher global marketing margins and favorable mark-to-market effects.

Phillips 66 also reached full production at the 220 MMCFD Dos Picos II gas plant. It announced a 300 MMCFD Zeus gas plant and a 100,000-barrel-per-day Coastal Bend NGL fractionator, while CPChem continued work on polymer projects in Texas and Qatar that are expected to reach full operations in 2027.

Profitability, cash flow and balance sheet

Operating cash flow of $7.259 billion exceeded the $4.317 billion generated excluding working-capital movements. The roughly $2.9 billion difference shows that working capital made a material contribution to reported quarterly cash generation.

Total debt declined from $27.124 billion at March 31 to $20.565 billion at June 30. Because cash and equivalents also fell from $5.150 billion to $4.099 billion, net debt decreased by $5.508 billion to $16.466 billion. The debt-to-capital ratio improved from 48% to 39%, while the net debt-to-capital ratio fell from 43% to 33%.

During the quarter, Phillips 66 spent $726 million on capital expenditures and investments and returned $887 million to shareholders, consisting of $508 million in dividends and $379 million in share repurchases. At quarter-end, the company had $4.1 billion in cash and $6.4 billion of committed credit-facility capacity.

Recent insider transactions

The supplied Yahoo Finance summary recorded 196,080 shares acquired across 16 transactions and 140,159 shares sold across nine transactions over the preceding six months, resulting in net acquisitions of 55,921 shares. Its acquisition category includes stock awards and derivative exercises; the only transactions explicitly classified as open-market purchases were two director purchases by Kevin Omar Meyers, each involving approximately 175 shares.

The latest 10 reported transactions included several instances in which CFO Kevin J. Mitchell exercised derivative securities and sold shares on the same date. These records describe the transactions but do not establish the insiders’ views on the company’s outlook.

Risks investors should monitor

• Refining-margin sensitivity: Much of the earnings increase came from higher crack spreads, a realized refining margin of $24.08 per barrel and favorable mark-to-market effects. Reversals in those factors could produce significant earnings volatility.
• Renewable-fuel credit exposure: The segment’s return to profit depended partly on higher regulatory credit pricing. Changes in credit prices or government renewable-fuel policies could affect both revenue and margins.
• Working-capital contribution to cash flow: Approximately $2.9 billion of reported operating cash flow reflected working-capital movements, making cash flow excluding working capital an important measure of underlying generation.
• Project execution: The Zeus gas plant, Coastal Bend fractionator and CPChem polymer projects introduce construction, permitting, cost and timing risks before they contribute fully to operations.

Summary

Phillips 66’s Q2 2026 improvement was driven primarily by higher refining margins, stronger crack spreads, regulatory credits and favorable mark-to-market effects, with Renewable Fuels also moving back into profit. Cash generation supported substantial debt reduction, although working capital contributed materially to reported operating cash flow. Future results will depend heavily on the durability of refining margins and renewable credits, continued operating performance and execution of the company’s expansion projects.
