TD Cowen has maintained Marathon Petroleum Corporation as its highest-ranked stock in the refining sector after the company hosted investors at its Garyville refinery, the research firm said. Its continued top placement reflects expectations that further value-chain improvements and organic project execution will raise refining capture rates in coming years.
TD Cowens forecast calls for a 16% free cash flow yield in 2026 and 12% in 2027, using a combined view of Marathons parent-level returns together with distributions from its midstream affiliate, MPLX.
Operational progress and optimization plans
Management at Marathon signaled that there remains a substantial runway for additional value-chain optimization, indicating that opportunities ahead exceed what has already been realized. The company plans to incrementally deploy initiatives that span cross-region coordination and daily optimization of refinery operations.
Projects within the refining portfolio are proceeding as planned. At Garyville, the jet project is producing above its target of 30,000 barrels per day. The facility as a whole is operating at 655,000 barrels per day, a level that surpasses its stated nameplate capacity of 617,000 barrels per day.
TD Cowens capital return expectations for Marathon are more aggressive than consensus. The firm anticipates $7.5 billion in share repurchases through the remainder of 2026 versus a consensus figure of $6 billion, and $6 billion in repurchases in 2027 compared with consensus of $5.2 billion. TD Cowen notes that the 2027 repurchase amount would represent roughly 18% of the companys market capitalization.
Midstream alignment and capital plans
MPLX, Marathons midstream subsidiary, conveyed that distributions beyond 2027 will be aligned with growth in distributable cash flow. Marathon also described management compensation structures that partially tie rewards to EBITDA per barrel by region and to MPLX distributable cash flow, linking operational performance to executive incentives.
The company is evaluating expansion of sour gas handling capabilities and is working to bring a new fractionation and liquefied petroleum gas (LPG) export facility online earlier than the prior 2028 target date.
Market outlook and recent results
Marathon stated that it does not expect a U.S. ban on product exports and said it is taking a conservative stance while anticipating robust crack spreads through the end of the year. Management cited operating in a maximum distillate mode and low gasoline inventories heading into the summer as supporting factors for that outlook.
In first-quarter 2026 results, Marathons parent reported revenue of $34.57 billion and earnings per share of $1.65, figures that topped expectations. Following those results, BMO Capital maintained an Outperform rating on the company. By contrast, MPLX reported first-quarter results whose revenue and earnings per share missed analyst forecasts.
Implications for stakeholders
For investors and market participants, TD Cowens sustained top ranking and the firms cash-return projections underscore a bullish operational and capital-allocation view for Marathon, assuming the company continues to convert projects and optimization initiatives into higher capture rates and cash flow.
Key details:
- TD Cowen projects 16% free cash flow yield in 2026 and 12% in 2027 combining Marathon and MPLX cash flows.
- Garyville refinery is operating at 655,000 barrels per day, above its 617,000 barrels per day nameplate capacity; the Garyville jet project is producing in excess of 30,000 barrels per day.
- TD Cowen expects $7.5 billion in repurchases through the remainder of 2026 and $6 billion in 2027, versus consensus of $6 billion and $5.2 billion respectively.
Conclusion
TD Cowens continued endorsement of Marathon as its top refining pick rests on a combination of operational outperformance at Garyville, an asserted pipeline of optimization opportunities, and a capital-return plan that exceeds street expectations. The midstream relationship with MPLX and the alignment of management incentives to regional EBITDA and distributable cash flow form part of the picture that underpins the research houses projections.
