USCF Midstream Energy Income Fund ETF (UMI)

The USCF Midstream Energy Income Fund ETF (NYSE: UMI) is a narrowly focused income fund that owns master limited partnerships and other companies operating the pipelines, storage tanks, processing plants, and terminals that transport and process oil, natural gas, and refined products. Because MLPs are required by law to distribute most of their cash to unit holders, UMI generates yields that are typically two to three times higher than the S&P 500 — a powerful draw for income investors, but one that comes with significant structural and tax complications.

What midstream energy companies actually do

The energy industry has three tiers. Upstream companies explore for and extract oil and gas from the ground. Downstream companies refine crude oil into gasoline and diesel, or process natural gas for use in power plants and homes. Midstream sits in between: it is the infrastructure — the pipelines, the compressor stations, the storage caverns, the tanker terminals — that moves physical products from where they are extracted to where they are refined or used.

A typical midstream company might own thousands of miles of pipeline that carry crude oil from wells in the Permian to refineries on the Gulf Coast, then collect fees for each barrel that passes through. Another might own a vast underground salt cavern where natural gas can be stored in summer and withdrawn in winter, earning the spread between low summer prices and high winter prices. The business is not glamorous, but it is essential: nothing moves without it, and because the infrastructure is so expensive to build and hard to replicate, companies with good assets enjoy durable competitive advantages.

Why master limited partnerships dominate this sector

Most midstream companies are structured as master limited partnerships, or MLPs — a legal form that is taxed like a partnership, not a corporation. In exchange, MLPs must distribute at least 90 percent of their cash to unit holders. This distribution requirement turns MLPs into yield machines: they cannot retain earnings to reinvest or store cash; they must send it out. Investors receive distributions (the MLP equivalent of dividends) that are often much larger than what a traditional corporation would pay, because the MLP is contractually obligated to do so.

The catch is taxes. MLP distributions are not the same as corporate dividends. They are a return of capital, and the tax treatment is complex: most of the distribution is not taxable in the year received but instead defers taxes and reduces your cost basis. When you sell, those deferred taxes hit in the form of a higher capital gain. Worse, if you hold an MLP in a regular taxable account, you will receive a Schedule K-1 at tax time — a document that can be dozens of pages long — instead of a simple 1099-DIV. This makes MLPs substantially more hassle to own outside of retirement accounts.

Why UMI owns MLPs even though they are tax-inefficient

UMI solves part of this problem by wrapping MLPs inside an ETF. When UMI collects distributions from its underlying MLPs, those distributions lose their partnership status — they are now distributed by a corporation (the ETF) to shareholders, generating a familiar 1099-DIV and no K-1. This is much simpler for tax filers.

The trade-off is that the ETF now pays corporate income tax on the distributions it receives before passing them to shareholders. This is a real drag: the MLP’s 8 percent yield to the partnership becomes a 6 or 7 percent yield to the ETF shareholder after the fund-level tax. It is still high, but not as high as owning MLPs directly. For investors who want midstream exposure but want to avoid K-1s and K-1 complexity, UMI is the answer. For tax-exempt investors (endowments, pension funds, IRAs), buying MLPs directly is usually better.

The risks: commodity cycles and rising rates

Midstream companies generate cash from volume and fees, not from the price of oil and gas. If crude oil drops from 80 dollars to 40 dollars a barrel, the pipeline company still collects the same fee per barrel. This gives midstream a defensive quality in commodity downturns that upstream exploration and downstream refining lack.

But midstream is not immune to cycles. In recessions, refineries run at lower capacity, power plants burn less gas, petrochemical producers cut output — and less product moving through pipelines means lower revenue for the midstream operators. The 2020 pandemic collapse saw midstream suffer, though less severely than upstream. Long-term, energy demand matters: in a world that materially reduces oil and gas consumption, midstream assets become less valuable.

A second risk is interest rates. MLPs are often compared to bonds — they offer predictable cash flows and high current income. When interest rates rise, bonds become more attractive, and MLP valuations compress as investors demand higher yields to hold them. In a rising-rate environment, UMI can underperform, sometimes sharply.

How to research midstream and UMI’s holdings

Start with the prospectus and the fund’s fact sheet, which list the top 10 holdings and the fund’s exposure to the major pipeline operators: companies like Energy Transfer, ONEOK, Cheniere Energy Partners, and Antero Midstream. Read the annual reports of a few of the largest holdings to understand what assets they own and what economic moats protect them. A pipeline that is the only way to move crude from a producing region has durable value; a new terminal that faces competition from three others has much less.

Watch energy demand indicators — crude oil inventory, natural gas storage, refinery utilization rates — to sense whether midstream companies are in a growth or contraction phase. And before buying, ask yourself honestly: do I have the stomach to hold UMI if crude oil crashes and interest rates rise at the same time? If the answer is no, midstream ETFs are not for you, no matter how attractive the yield looks.
