Pipeline stocks like MPLX and Energy Transfer keep handing investors yields above 6%, but the cash flow statements hiding beneath those steady checks tell a very different story about how safe those payouts actually are.
Pipelines are where income investors go for yield, and MPLX (NYSE:MPLX | MPLX Price Prediction) pays about 7.4% at a unit price of $58.18. Long contracts make that check look safe. The risk sits in how the industry pays for growth. It hands most of its operating cash to investors and borrows to build. The practice is so common that few investors treat it as a warning sign anymore, and that is what makes it risky.
One key check: a payout holds up when operating cash flow covers both growth spending and the dividend. When it falls short, debt fills the gap, and the payout depends on lenders remaining generous.
Why Pipelines Borrow to Pay You
The model makes sense. Pipeline assets last for decades. ONEOK (NYSE:OKE) says about 90% of its earnings are fee-based. The newest projects at Kinder Morgan (NYSE:KMI) run on “at least 20-year take-or-pay contracts”. Partnerships are built to pass cash through to unitholders. Demand keeps coming, too. Federal forecasters say rising Appalachian gas output “requires infrastructure buildout to move natural gas to the Gulf Coast”. Put together, that means the industry pays out its cash and borrows for new projects.
This screen covers Energy Transfer (NYSE:ET), Williams Companies (NYSE:WMB), MPLX, ONEOK, Kinder Morgan and Enterprise Products Partners (NYSE:EPD), ordered from most exposed to most conservative. These yields hold up even as share prices have risen. Energy Transfer is up 28.66% year to date, and MPLX is up 15.44%. The warning signs are in the cash flow statements.
Energy Transfer (ET): Debt Climbing Faster Than the Payout
Energy Transfer yields about 6.8% on a $1.36 annualized distribution and has raised the payout for 19 straight quarters. Second-quarter distributable cash flow (DCF), the key coverage metric for a partnership, was $2.6 billion. That covered the $1.241 billion paid out about 2.1x.
Full-year figures show more pressure. In 2025, operating cash flow of $10.149 billion came up $879 million short of covering capex and distributions combined. Total debt reached $70.241 billion, up from $60.558 billion at the end of 2024. Management expects growth spending of “$5 billion plus” each year through the end of the decade, and its leverage target is 4 to 4.5 times EBITDA. Energy Transfer has cut before: quarterly distributions paid fell from $819 million to $405 million in late 2020. To keep the payout safe, signed projects like Hugh Brinson need to increase up as planned.
Williams (WMB): Spending Now Outruns Operating Cash
At about 3.0%, Williams has the lowest yield in the group. It also has the tightest cash position. Second-quarter capex of $1.834 billion was higher than operating cash flow of $1.376 billion, and cash fell 77.5% to $203 million. Growth capex guidance of $7.3 to $7.9 billion is close to adjusted EBITDA guidance of $8.3 to $8.5 billion. On top of that, the Momentum Midstream deal adds $5.5 billion and brings pro forma leverage to about 3.75x. Momentum and the power projects have to deliver EBITDA on schedule.
MPLX (MPLX): Fast Raises Meet a Bigger Build
MPLX pays $1.0765 per quarter and plans 12.5% increases in both 2026 and 2027. DCF of $1.45 billion covers the distribution about 1.34x. However, second-quarter operating cash flow fell $215 million short of capex plus distributions. The partnership also raised 2026 capex guidance by $500 million to $2.9 billion. Leverage is 3.7x against a 4.0x ceiling. The CFO said growth later in 2026 “is going to give us confidence in 1.3x” coverage, so that increase has to show up.
ONEOK (OKE): A Thin Cash Cushion Behind a Steady Check
ONEOK yields about 4.6%. In the first quarter of 2026, operating cash flow was $934 million, versus $864 million in capex and $674 million in dividends. At midyear, debt stood at $33.022 billion while cash was just $161 million. In its favor, ONEOK expects capex to ease toward $2 billion to $2.5 billion a year, and cash-tax benefits of about $2.6 billion should help free cash flow.
Kinder Morgan (KMI): Conservative, With a Growing Bill
Kinder Morgan yields about 3.4%. Year to date, it generated $5.04 billion in operating cash, paid $1.98 billion in dividends, and has leverage of 3.5 times. The project backlog, though, grew to $14.4 billion. Management also said about $225 million of the 2026 outperformance came from items that may not repeat.
Enterprise Products Partners: Benchmark for Coverage
Enterprise yields about 6.1% and covers its distribution 1.9x on a DCF basis. Its leverage remains at a 3.0 target, and 97% of its debt is fixed-rate at an average cost of 4.7%. It still plans about $3 billion of growth capex in 2027.
What Could Break the Model
Borrowing to grow works as long as credit remains cheap. Three things could break it:
- Refinancing at higher interest rates.
- Lenders pulling back.
- A drop in demand that reduces the cash flow used to justify the debt.
Enterprise’s fixed-rate debt protects it. Energy Transfer runs at higher leverage, which leaves it more exposed.
When a dividend gets cut, the share price usually falls with it, so a high yield alone doesn’t justify buying a stock (we outlined the main red flags before a big payout gets cut in a free report here: Dividend Traps). In pipelines, start by checking DCF coverage, then free cash flow after the payout, then where leverage is heading.
