MPLX (MPLX) Stock Looks Reasonable On Earnings While Returns Look Stretched

MPLX has delivered a very strong 5 year share price return, yet the stock still screens as undervalued on several key checks. This raises the question of how much of its growth pipeline is already reflected in today’s US$58.46 price.

• The unit price has gained 220.2% over the past 5 years, which puts longer term holders in a strong position and makes fresh valuation checks especially important.
• RBC’s focus on MPLX’s project ramp up and its stake in new Permian to Gulf Coast pipeline capacity can support expectations for future cash flows. At the same time, the recent US$2b of new debt and ongoing acquisition plans may add financing and execution risk to that outlook.
• MPLX scores highly on Simply Wall St’s checks and is assessed as undervalued in 5 of 6 valuation tests, which suggests the broader indicators lean cheap rather than fully pricing in its past returns.

The issue now is whether MPLX’s current price still leaves enough upside to compensate for the project and balance sheet risks that come with its growth plans.

Find out why MPLX's 25.6% return over the last year is lagging behind its peers.

Is MPLX Still Cheap on Earnings?

The P/E ratio fits MPLX well because earnings are a key driver for investors watching its fee based midstream cash flows. On this metric, MPLX trades on a P/E of 12.5x, which is slightly below the Oil and Gas industry average of 13.0x and sits at a discount to the peer group average of 20.6x. That indicates a modest earnings based discount, even after the strong unit price performance over the past five years.

The tailored fair P/E ratio for MPLX is 22.9x, which reflects what investors might typically pay given its earnings profile, industry, size and risk factors. The current 12.5x multiple is therefore well below this benchmark. Despite the recent news on new Permian to Gulf Coast pipeline capacity and the US$2b debt raise to support acquisitions and projects, the earnings multiple still prices MPLX at a discount to the level suggested by this model.

On a P/E basis, MPLX appears undervalued, with its earnings multiple sitting well below both peers and the modelled fair ratio.

The Bottom Line

MPLX still screens as undervalued on earnings compared with both its industry and tailored fair P/E anchor, even after a strong 5 year run. The key question is whether that discount reflects overlooked cash flow potential or a reasonable cushion for project execution and balance sheet risk tied to new pipelines and recent debt raising. What matters from here is whether MPLX can deliver on its growth plans without eroding returns to unitholders through higher financing costs or delayed project benefits.
