Find your next quality investment with Simply Wall St’s easy and powerful screener, trusted by over 7 million individual investors worldwide.

With Marathon Petroleum trading at US$253.56, many investors are asking the same question: is the stock pricing in too much optimism, or is there still value on the table?

The share price performance is strong, with returns of 4.4% over 7 days, 2.2% over 30 days, 53.5% year to date, 54.3% over 1 year, 131.8% over 3 years, and 366.0% over 5 years, which naturally raises questions about what is already embedded in the price.

Recent news coverage has focused on Marathon Petroleum’s position within the broader energy sector and how investors are weighing refining exposure against other parts of the market. Commentary has also highlighted how company specific developments and capital allocation decisions are feeding into sentiment, which helps explain some of the share price strength you see in the recent returns.

Marathon Petroleum currently has a value score of 3/6. This indicates it screens as undervalued on half of the six checks used. The next sections will walk through the different valuation approaches behind that score, while also pointing to an even more useful way to think about valuation at the end of the article.

Approach 1: Marathon Petroleum Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model projects a company’s future cash flows and then discounts them back to today’s value, giving an estimate of what the entire business might be worth per share.

For Marathon Petroleum, the model used here is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $6.7b. Analyst estimates and subsequent extrapolations suggest free cash flow of $11.0b in 2026 and $5.9b in 2030, with Simply Wall St extending these projections out to 2035 using its own assumptions.

When those projected cash flows are discounted back to today, the DCF model points to an estimated intrinsic value of $416.08 per share. Compared with the current share price of $253.56, this implies the stock screens as about 39.1% undervalued on this measure.

Approach 2: Marathon Petroleum Price vs Earnings

For profitable companies like Marathon Petroleum, the P/E ratio is a common way to think about value because it links what you pay for the stock directly to the earnings it generates. In general, higher growth expectations and lower perceived risk can justify a higher P/E, while slower growth and higher risk usually point to a lower, more cautious multiple.

Marathon Petroleum currently trades on a P/E of 16.0x. This sits slightly above both the Oil and Gas industry average P/E of 12.9x and the peer group average of 15.3x. Simply Wall St also provides a proprietary “Fair Ratio” of 18.5x, which is the P/E level its model suggests could be reasonable given factors such as earnings growth characteristics, industry, profit margins, market cap and risk profile.

The Fair Ratio is more tailored than a simple comparison with peers or the industry because it adjusts for company specific traits rather than assuming that all Oil and Gas companies deserve the same multiple. Comparing the Fair Ratio of 18.5x with the current P/E of 16.0x, Marathon Petroleum is described as undervalued on this metric.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Marathon Petroleum Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives are introduced here as a simple way for you to attach a clear story about Marathon Petroleum, including your view on fair value and future revenue, earnings and margins, to the numbers on screen.

On Simply Wall St, Narratives link that story to a financial forecast and then to a Fair Value estimate. This allows you to quickly compare your view with the current share price to help decide whether the stock looks attractive, fully priced or expensive based on your own assumptions.

Narratives sit in the Community page and are designed to be easy to use. They update automatically when fresh information such as news or earnings is added, which helps keep the story, the forecast and the Fair Value aligned without you rebuilding a model from scratch.

For Marathon Petroleum, for example, one investor might build a Narrative around the higher analyst Fair Value of about US$318.81 with earnings assumptions closer to US$8.6b. Another might lean toward the more cautious Fair Value of about US$163.00 with earnings closer to US$3.4b. By comparing each Fair Value with the current price they can decide which story, if any, they are comfortable acting on.

For Marathon Petroleum, however, we will make it really easy for you with previews of two leading Marathon Petroleum Narratives:

These sit at opposite ends of the current community range, so you can quickly see how different assumptions on refining margins, earnings and long term demand for fuels translate into very different views on what the stock might be worth.

🐂 Marathon Petroleum Bull Case

Fair value used in this bullish narrative: US$271.59 per share.

The current price of US$253.56 is about 6.6% below that fair value estimate.

Analyst revenue outlook in this narrative points to an annual contraction of about 23.4%.

Focuses on strong product demand, tight refining capacity and portfolio optimisation that support higher utilisation, firmer margins and cash generation for Marathon Petroleum.

Assumes steady progress on buybacks, MPLX distributions and select renewables projects, which together support earnings per share and flexibility in capital returns.

Flags that long term exposure to fossil fuels, policy risk and the relatively small renewables footprint could still pressure volumes and margins if decarbonisation trends accelerate.

🐻 Marathon Petroleum Bear Case

Fair value used in this bearish narrative: US$163.00 per share.

The current price of US$253.56 is about 35.6% above that fair value estimate.

Analyst revenue outlook in this narrative points to an annual contraction of about 2.2%.

Highlights that large refining projects and sour crude exposure at Marathon Petroleum could be vulnerable if crack spreads, differentials or global fuel tightness ease from current conditions.

Questions whether planned midstream and NGL projects, along with expected MPLX distributions, will achieve targeted returns if LNG, gas and export demand soften or are delayed.

Warns that if these pressures play out, earnings and free cash flow could fall short of current expectations, making the recent share price look demanding against the bearish fair value.

If you want to go beyond the previews and see how your own assumptions on margins, demand and capital returns stack up against these community views, it is worth reading the Narratives in full and tracking how they evolve as new data comes through, including See what the community is saying about Marathon Petroleum.
