MPLX is a master limited partnership (MLP) formed by refining giant Marathon Petroleum to own and operate midstream energy infrastructure and logistics assets. The MLP has two focus areas: crude oil and products logistics, and natural gas and natural gas liquids (NGL) services. The company's pipelines, processing plants, storage terminals, and export facilities generate fairly stable earnings, backed by government-regulated rate structures and long-term contracts with high-quality customers, such as Marathon.
The midstream company has generated $2.6 billion in distributable cash flow through the first half of this year, representing a 5% increase from the same period last year. That provided it with enough money to cover its cash distribution payments by 1.5 times. That's a comfortable level for the MLP, which generated over $950 million in excess free cash flow after paying distributions. That performance allowed MPLX to return an additional $200 million to investors by repurchasing some of its units while retaining the remaining funds to invest in its continued expansion.
MPLX further fortifies its lucrative distribution payment with a strong balance sheet. The MLP ended the second quarter with a low 3.1 leverage ratio. That's comfortably below the 4.0 range its stable cash flows can support.
These financial metrics suggest that MPLX's high-yielding distribution isn't a trap. The payout is on a very sustainable foundation with minimal risk of a reduction on the horizon.
MPLX offers investors more than a bond-like income stream. The MLP is growing its earnings at a healthy mid-single-digit annual rate, which should continue.
The MLP currently has a long list of organic expansion projects under construction:
Those projects will provide the MLP with growing streams of incremental earnings and cash flow through the end of the decade.
In addition, MPLX is using its financial flexibility to make acquisitions. It agreed to buy Whiptail Midstream, the remaining 55% of the BANGL pipeline, a 5% interest in the Matterhorn Express Pipeline, and Northwind Midstream this year. At nearly $2.4 billion, Northwind is the largest deal. The transaction will immediately boost its earnings and cash flow, while providing additional growth in 2026 from in-process expansion projects. The company has ample financial capacity to continue approving expansion projects and making acquisitions as new opportunities arise.
The MLP's growth catalysts will provide it with plenty of fuel to continue increasing its distribution. MPLX has raised its payout every single year since its formation in 2012. It has delivered robust distribution growth in recent years, with 10.7% compound annual growth since 2021. Distribution growth is likely to moderate in the future to align with the mid-single-digit growth rate of its cash flow.
MPLX offers investors a rock-solid distribution yielding over 7.7%. However, that's not all. It also has a healthy growth profile that extends through the end of the decade, giving it the fuel to continue increasing its distribution. This combination of high income and solid growth positions the MLP to potentially produce high-octane total returns in the coming years. If you're comfortable with the Schedule K-1 federal tax form that the MLP sends its investors each year, MPLX is a no-brainer buy for income and upside potential.
