Material Changes vs. Prior Period

- Midstream: Adjusted EBITDA decreased to $1,598 million from $1,720 million, impacted by derivative losses and acquisition/divestiture activity.
- Renewable Diesel: Adjusted EBITDA improved to $38 million from a loss of $42 million, aided by clean fuel production tax credits.
- Cash Flow: Operating cash flow swung from a $64 million use of cash in Q1 2025 to a $1.12 billion source in Q1 2026, driven by improved operating results and favorable working capital changes.

Investor Verification Checklist

- Refining Margins: Confirm the sustainability of the $17.74 per barrel margin against current crack spreads and crude differentials.
- Capital Allocation: Review the utilization of the new $5.0 billion share repurchase authorization versus capital expenditure needs ($1.01 billion in Q1 2026).
- Midstream Acquisitions: Assess the integration and performance of recent acquisitions (Northwind Midstream, BANGL) and their contribution to EBITDA.
- Legal Contingencies: Monitor the status of climate change litigation and the Tesoro High Plains Pipeline trespass dispute, which could result in material liabilities.
