Summit Midstream (NYSE: SMC) raises EBITDA outlook, but free cash flow falls 68.7%

What happened

Summit Midstream Corporation (NYSE: SMC) raised its 2026 Adjusted EBITDA guidance to $250 million to $260 million on Nov. 9. The prior range was $235 million to $255 million. By OptimistFi's calculation, the midpoint moves to $255 million from $245 million, a $10 million or 4.1% increase.

The raise follows a third quarter in which Adjusted EBITDA reached $70.7 million, up 16% from the second quarter. By OptimistFi's calculation, that is 7.9% above the $65.5 million of the third quarter of 2025. Net income was $15.9 million, compared with $5.0 million a year earlier.

Summit also reached a final investment decision on the Double E Mainline Compression Expansion. The company says it positions Summit to serve growing Permian Basin customer demand.

Where the growth came from

The Rockies drove the quarter. Rockies Segment Adjusted EBITDA rose 32% from the second quarter to $40.0 million, on a 40% increase in liquids volume throughput. Summit connected 51 new wells, 32 in the Williston Basin and 19 in the DJ Basin.

Third-quarter results also include about $3.7 million of commercial billing settlements, which are not volume growth.

In the Permian, Double E throughput rose 17% from the second quarter to a record 1,002 MMcf/d. The Permian Segment reported Adjusted EBITDA of $11.2 million. Mid-Con Segment Adjusted EBITDA rose 7% to $22.8 million on a 7% increase in natural gas throughput to 561 MMcf/d.

Piceance moved the other way. Its segment Adjusted EBITDA fell $0.4 million from the second quarter to $8.3 million, as higher operating expenses offset a 4.2% volume increase. The minimum volume commitments behind Piceance gathering agreements expired at the end of the quarter. They account for substantially all of SMC's shortfall payments under such commitments. Those payments added $4.1 million of Adjusted EBITDA in the third quarter.

Why it matters

OptimistFi has argued that Summit's value rests on its systems staying essential to producers in core shale areas while debt comes down. The quarter supports the first half of that view.

Seven rigs are running behind Summit's systems with approximately 140 DUCs. The company expects to connect 200 to 250 wells in 2027. Management said the Rockies and Permian outlook, along with a steady Mid-Con, could drive a mid-to-high-teens compound annual growth rate in Adjusted EBITDA over the next several years. That is a forecast, not a result.

The cash flow side is weaker. Free cash flow was $5.2 million, down 68.7% from $16.7 million in the third quarter of 2025 by OptimistFi's calculation, even as Adjusted EBITDA rose. Distributable Cash Flow fell to $32.6 million from $36.7 million. The free cash flow reconciliation deducts $10.9 million of investment in equity method investees, against $0.75 million a year earlier.

Debt, liquidity and spending

Leverage is the open question. Total net leverage was approximately 3.9x at Sept. 30. Summit expects approximately 3.6x at year-end based on the midpoint of the updated EBITDA range. Under the ABL credit agreement, the ratio excludes the $360 million Permian Transmission Term Loan, which is non-recourse to SMC.

That agreement also counts cash distributions from Double E in place of SMC's proportional share of its Adjusted EBITDA. Long-term debt, net was $1.25 billion at Sept. 30, against $1.02 billion at Dec. 31, 2025.

Covenants have room. Interest coverage was 3.0x against a 2.0x minimum. First lien net leverage was 0.3x against a 2.5x maximum. Summit had $80 million drawn on its $500 million ABL Revolver, $417 million of borrowing availability and $12.5 million of unrestricted cash.

Spending is rising with the growth. Summit expects 2026 capital expenditures, including Double E, of $100 million to $120 million. That is near the high end and up from an original $85 million to $105 million. It cites 30 additional Williston wells and new Double E firm transportation agreements. Third-quarter capital expenditures were $21.2 million.

The board continued to suspend common dividends. Summit repurchased 7,007 shares for about $0.2 million in the quarter. That leaves about $33.8 million of capacity under its $35.0 million program.

What's next

Summit hosts its earnings call at 10:00 a.m. Eastern on Nov. 10. Management attends the Bank of America Leveraged Finance Conference on Dec. 1 to 2 and the Wells Fargo Energy Power Symposium on Dec. 8 to 9.

The company said it remains on track to fully subscribe the remaining Double E forward-haul capacity by year-end. It will give more specific 2027 financial guidance early next year. A year-end leverage ratio near 3.6x and a rebound in free cash flow would back the deleveraging case. Leverage staying near 3.9x or free cash flow staying near this quarter's level would weaken it.
