Enbridge, Oneok Face Divergent Paths as Energy Midstream Demand Holds

The energy midstream sector is not a monolith, even when the headline story sounds the same. Enbridge and Oneok both move oil and gas across North America. Both pay dividends north of 4%. Both have spent years telling investors that demand for their infrastructure will grow regardless of what OPEC does or where crude settles.

But the numbers behind each company tell a different story about who is positioned for the next few years and who is running harder just to stay in place.

Enbridge reported second-quarter results that showed the core liquids pipelines business holding steady. Mainline throughput averaged 3.0 million barrels per day, roughly in line with the same quarter last year. The company affirmed its 2026 adjusted EBITDA guidance range of C$19.4 billion to C$20.0 billion. That is not a miss, but it is also not the acceleration some investors had hoped for after the company closed its US$14 billion acquisition of three gas utilities from Dominion Energy in 2024.

That deal added 9,400 miles of gas distribution pipes and roughly 3 million customer connections across Ohio, North Carolina, Utah, Wyoming, and Idaho. On the call, CFO John Whelen said the integration was on track and that the utilities would contribute about C$2.4 billion in EBITDA this year. The market's response was muted. Enbridge shares are up about 3% over the past six months, lagging the broader energy sector.

The concern is not about the assets. It is about the balance sheet. Enbridge ended the quarter with net debt to adjusted EBITDA at 4.6 times, above the 4.0 times target the company has set. Management said it expects leverage to fall below 4.5 times by year-end as cash flows from the new utilities build. But that leaves little room for a major new project or an acquisition unless the company issues equity or sells assets, neither of which management has signaled.

Oneok's quarter looked different. The company reported adjusted EBITDA of US$1.52 billion for the second quarter, up 16% from a year earlier. The growth came from its refined products and natural gas liquids segments, where volumes rose 12% and 9% respectively. Oneok has been spending aggressively on its own expansion. It closed the US$5.9 billion acquisition of Medallion Midstream in 2024, adding crude oil gathering assets in the Permian Basin. It also launched the US$1.4 billion Saguaro natural gas pipeline project, which will move gas from the Permian to the Waha hub and connect to Gulf Coast markets.

Oneok's leverage is lower than Enbridge's, at 3.8 times net debt to EBITDA. That gives it more flexibility to fund growth without straining the dividend. The company raised its dividend by 4% this year, marking the 11th consecutive annual increase. The yield sits at 4.5%.

Enbridge has a longer dividend track record, with 31 consecutive years of increases in Canadian dollars. But the growth rate has slowed. The company raised its dividend by 3% for 2026, down from 5% the year before. That is still a raise, but it signals that management is being cautious about how much cash it can return to shareholders while paying down debt.

On the AlphaScala scoring system, Enbridge carries a score of 58 out of 100, labeled Moderate. Oneok scores 55, also Moderate. Neither is flashing a strong buy signal on that metric alone. But the scores reflect different risk profiles. Enbridge's score is dragged by its leverage and slower earnings growth. Oneok's is held back by its higher capital spending relative to cash flow, a trade-off that could pay off if the new pipelines fill as expected.

What both companies share is exposure to North American energy demand, which remains robust. The U.S. Energy Information Administration expects domestic natural gas consumption to rise by about 2% this year, driven by power generation and liquefied natural gas exports. Oil demand is flat but not falling. The midstream business model works as long as the pipes keep flowing. The question is which company has the balance sheet to keep building them.

For now, Enbridge is the safer yield at 4.9%, with a longer track record and a more conservative approach. Oneok offers a slightly lower yield but faster earnings growth and a cleaner balance sheet. The dividend investor who wants to hold through 2030 can make a case for either. The case for owning both is weaker. They are not the same bet, even if the sector label says they are.
