Approach 1: MPLX Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes estimates of the cash a business could generate in the future and discounts those cash flows back to today to arrive at an intrinsic value per unit.

For MPLX, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $4.57b. Analyst estimates and subsequent extrapolations in the model point to free cash flow of around $5.58b by 2030, with a series of annual projections between 2026 and 2035 that are discounted back to present values.

Bringing all those projected cash flows back to today produces an estimated intrinsic value of about $135.09 per unit. Compared with a recent unit price around $57, the DCF output in this model suggests MPLX trades at a 57.5% discount to this intrinsic value, indicating the units are priced below what this particular model implies.

Result: UNDERVALUED (per this DCF model)

Our Discounted Cash Flow (DCF) analysis suggests MPLX is undervalued by 57.5%. Track this in your watchlist or portfolio, or discover 49 more high quality undervalued stocks.

Approach 2: MPLX Price vs Earnings

For a profitable business like MPLX, the P/E ratio is a straightforward way to relate what you pay per unit to the earnings generated per unit. It ties directly to the cash the business is producing today, which many investors find easier to anchor than long range forecasts.

What counts as a “normal” P/E depends on what the market expects for earnings growth and how much risk investors see in those earnings. Higher expected growth or lower perceived risk often go with higher P/E ratios, while slower growth or higher risk usually mean lower P/E ratios.

MPLX currently trades on a P/E of 11.86x. That sits below the Oil and Gas industry average of 15.71x and below a peer group average of 20.12x. Simply Wall St’s Fair Ratio for MPLX is 23.95x, which is a proprietary estimate of the P/E that would be reasonable given factors such as its earnings growth profile, profit margins, industry, market cap and key risks.

The Fair Ratio can be more tailored than a simple comparison with peers or the industry because it adjusts for company specific characteristics rather than treating all pipeline or midstream names the same. Comparing 11.86x to the Fair Ratio of 23.95x points to MPLX trading below what this model suggests could be a fair earnings multiple.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your MPLX Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Think of a Narrative as your own clear story for MPLX that links what you believe about its business, future revenue, earnings and margins to a financial forecast, a Fair Value, and finally a comparison with today’s price. All of this happens within an easy tool on Simply Wall St’s Community page that millions of investors use. Narratives refresh automatically when new information such as earnings or news arrives. One investor might look at the higher analyst target of US$64 and build a more optimistic MPLX story, while another might anchor on the lower US$51 target and build a more cautious view. Both can then see how their chosen Narrative translates into a Fair Value vs price gap that helps them decide whether the units currently look appealing, fully priced, or closer to a hold in their own framework.
