US Refining Investments Will Secure Future Market Opportunities

Key Takeaways

• Strong product demand and capacity reductions support high refinery utilization, improved margins, and revenue growth in supply-constrained markets.
  
• Portfolio optimization, disciplined capital allocation, and investment in renewables bolster operational flexibility, shareholder returns, and long-term resilience.
  
• Heavy reliance on fossil fuels and refining investments leaves Marathon Petroleum vulnerable to stricter environmental policies, declining demand, and limited diversification into renewables.

Catalysts

Operates as an integrated downstream energy company in the United States.

• Ongoing strong demand for gasoline, diesel, and jet fuel-driven by resilient U.S. transportation needs, continued ICE vehicle prevalence (especially in states like California), and sustained global population and urbanization trends-positions Marathon for high throughput volumes and stable-to-rising revenue streams for the remainder of the decade.
  
• Structural industry capacity reductions, especially on the U.S. West Coast with peer refinery closures, are causing regional product shortages; Marathon's investments in efficiency, reliability, and emissions reduction at its LA refinery are expected to improve utilization and allow capture of higher margins and revenues in increasingly supply-constrained markets.
  
• Strategic portfolio optimization, including high-return refinery "quick hit" projects and ongoing expansion in midstream logistics/NGL infrastructure (such as the Northwind Midstream acquisition), are enhancing operational flexibility and supporting incremental improvement in net margins and long-term cash flow generation.
  
• Disciplined capital allocation through continued share buybacks, increasing MPLX distributions, and maintenance of an investment-grade balance sheet are set to drive higher earnings per share and sustained shareholder returns, aligning with positive long-term company trends.
  
• Investments in renewable fuels capacity and digital/autonomous refinery technology provide incremental but growing future revenue streams, greater cost efficiencies, and improved long-term net margins, positioning the company well as demand shifts and carbon regulation increases over time.

Marathon Petroleum Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Marathon Petroleum's revenue will decrease by 2.6% annually over the next 3 years.
• Analysts assume that profit margins will increase from 1.6% today to 3.4% in 3 years time.
• Analysts expect earnings to reach $4.2 billion (and earnings per share of $15.16) by about September 2028, up from $2.1 billion today. However, there is a considerable amount of disagreement amongst the analysts with the most bullish expecting $5.2 billion in earnings, and the most bearish expecting $2.8 billion.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 13.9x on those 2028 earnings, down from 26.1x today. This future PE is greater than the current PE for the US Oil and Gas industry at 12.6x.
• Analysts expect the number of shares outstanding to decline by 5.4% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.7%, as per the Simply Wall St company report.

Marathon Petroleum Future Earnings Per Share Growth

Risks

• Marathon Petroleum's revenues remain heavily exposed to declining long-term demand for petroleum products due to accelerating electrification and decarbonization trends in transportation, which could structurally erode volumes for gasoline, diesel, and jet fuel production-directly impacting future top-line revenues.
  
• The company's large refining footprint, with ongoing investments into refining assets (e.g., in California and major multiyear projects), risks asset stranding or value impairment if environmental policies or carbon pricing become significantly stricter, thereby compressing net margins and leading to possible write-downs or higher compliance/operating costs.
  
• Although Marathon is investing in renewable diesel, this segment constitutes only a small fraction of its total throughput; limited scale and lingering market uncertainty mean renewable fuels may not offset broader declines in fossil fuel margins, thereby threatening earnings diversification and future profit growth.
  
• Wider global adoption of biofuels, synthetic fuels, and accelerated improvements in electric vehicle penetration, particularly in developed markets, could result in meaningful and sustained declines in the demand for refined products, pressuring overall industry utilization rates, compressing refining margins and earnings stability.
  
• The company's capital allocation towards traditional refining, heavy turnaround spend, and continued inorganic growth in midstream assets potentially constrains its financial flexibility to pivot rapidly into low-carbon opportunities, while high debt obligations could expose Marathon to higher financing costs as ESG pressures grow and lenders reduce support for fossil-fuel-centric business models-adversely affecting net income and credit ratings.

Valuation

• The analysts have a consensus price target of $180.444 for Marathon Petroleum based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $206.0, and the most bearish reporting a price target of just $142.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $123.8 billion, earnings will come to $4.2 billion, and it would be trading on a PE ratio of 13.9x, assuming you use a discount rate of 7.7%.
• Given the current share price of $183.18, the analyst price target of $180.44 is 1.5% lower. The relatively low difference between the current share price and the analyst consensus price target indicates that they believe on average, the company is fairly priced.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
