Why MPLX’s latest distribution move matters

MPLX (MPLX) recently lifted its distribution payment by 12.5%, a move supported by long-term contracts, regulated rate structures, and a multiyear pipeline of organic projects scheduled through 2029.

The higher distribution comes as MPLX’s share price has also been firm, with a 90 day share price return of 9.32% and a 1 year total shareholder return of 15.75%. This suggests momentum has been building over both income and capital returns.

If MPLX’s mix of income and infrastructure appeals to you, this could be a good moment to broaden your watchlist with aerospace and defense stocks as another area of the market to research.

With MPLX trading at US$55.62, modestly below an analyst price target of US$57.23 and showing solid multi year total returns, the key question is whether this income heavyweight is still mispriced or whether markets are already pricing in future growth.

Price-to-Earnings of 11.8x: Is it justified?

At a P/E of 11.8x and a last close of US$55.62, MPLX screens as undervalued compared with both its peers and an estimated fair P/E level.

The P/E ratio links what you pay today to the earnings the business is already generating, which is particularly relevant for a cash generative midstream operator. For MPLX, this means the market is valuing each dollar of current earnings at a discount to what similar oil and gas names trade on.

Against the US Oil and Gas industry average P/E of 13.5x, MPLX sits on a lower multiple, and it also stands below the peer average of 20.6x. The estimated fair P/E of 20.1x is materially higher than the current 11.8x. This gap highlights how far sentiment could shift if pricing were to move closer to that fair ratio level.

Result: Price-to-Earnings of 11.8x (UNDERVALUED)

However, steady distributions still face risks, including energy demand shifts that could affect volumes and the influence of parent Marathon Petroleum on future capital and payout decisions.

Another view, using future cash flows

While the 11.8x P/E paints MPLX as cheap, our DCF model takes a different angle and values the units at US$127.09 based on future cash flows, versus the current US$55.62 price. That signals a much wider gap. Is the market missing something? Or are the cash flow assumptions too generous?
