Summit Midstream Corp (SMC) stock intrinsic value fair value estimate & owner earnings analysis

Summit Midstream Corporation gathers, processes and transports natural gas -- along with some crude oil and produced water -- for producers across five US regions: the DJ Basin and Piceance Basin in Colorado, the Williston Basin in North Dakota, the Permian/Delaware Basin in New Mexico and Texas, and the Mid-Continent in Oklahoma. It also owns 70% of the Double E Pipeline, a long-haul gas pipeline to the Waha, Texas hub, alongside ExxonMobil's 30%. The business looks very different today than it did two years ago. In December 2024 the company closed a $425 million acquisition of Tall Oak Midstream in Oklahoma and added the Moonrise system, roughly doubling its Mid-Continent footprint; around the same time it sold a large slice of its older pipeline joint-venture stakes for about $333 million and used part of the proceeds to restructure its balance sheet. The parent entity also converted from a limited partnership into a regular corporation in August 2024, which triggered a one-time, non-cash tax charge large enough to swamp that year's reported results. Because of that, 2024 is not representative of the business going forward, and 2023 describes a meaningfully smaller company that no longer exists in its current form. Fiscal 2025 is the first full year after the transformation and is the year this valuation is anchored to. On that basis, the company generated $133.6 million of operating cash flow in 2025. After removing the swing in working capital and the cost of stock-based compensation, and after deducting the capital spending needed just to sustain existing gathering systems (separate from spending that adds new wells or new geography), and after setting aside the cash that goes to preferred shareholders and to a subsidiary-level preferred unit that sits ahead of common stock, roughly $38 million -- about $3.14 per diluted share -- was left for common shareholders in 2025. The maintenance-spending estimate used here is deliberately cautious: it assumes future maintenance needs scale with revenue growth the way they have historically. The company's own reporting splits its 2025 capital spending more favorably, citing only about $17 million of its $89 million total as strictly required to sustain existing operations (versus roughly $70 million on our estimate); using the company's own split would put owner earnings closer to $6 per share. We used the more conservative figure because unconventional gas wells decline faster than conventional ones, and the company's own filings flag that this can require higher sustaining capital over time than a simple split implies. Three cases, each built from things the company has already done or already has on contract, not from hoped-for outcomes: Base case ($64/share): 2026 owner earnings per share are roughly flat versus 2025, since the company's own guidance calls for $85-105 million of 2026 capital spending (up from $89 million), absorbing the benefit of continued revenue growth (revenue was up about 8% year-over-year through the first half of 2026). From 2027 onward, growth resumes at a mid-single-digit pace as a 2025 precedent agreement for 100 million cubic feet/day of new Double E Pipeline capacity, tied to a processing-plant expansion in Lea County, New Mexico, and a new 15-year gathering agreement signed in 2025 with a key Williston Basin customer, phase in. Growth tapers toward the back half of the ten-year window, in line with the roughly 6.5-year average remaining life of Double E's current take-or-pay contracts, and beyond year ten we assume the business holds its earning power flat rather than keeps growing -- there isn't a specific, dated commitment to point to beyond that horizon, but the pipeline network itself, and a demonstrated pattern of re-contracting (Double E has added capacity commitments repeatedly since 2020), support the earnings persisting at that level rather than fading to zero. Bull case ($81/share): the 2025 Double E precedent agreement and a second capacity agreement for 210 million cubic feet/day signed after year-end 2025 both execute on schedule, the new Williston contract performs, and maintenance spending comes in closer to the company's own lower estimate rather than our more conservative one. Owner earnings grow at a high-single-digit rate in the first several years, moderating over the decade. Bear case ($33/share): commodity prices weigh on the roughly 48% of 2025 revenue tied to processing and other volume/price-sensitive activity (as opposed to fixed gathering fees), maintenance spending trends toward the higher end implied by faster well-decline rates, and no capacity beyond what is already contracted gets added. The company carries $825 million of 8.625% second-lien notes due October 2029, and that maturity is refinanced at a similar or modestly higher rate given the size and structure of the debt. Owner earnings decline over the first few years before leveling off. What would have to be true for the shares to be worth meaningfully less than even the bear case: gas prices fall further and stay down for years, a producer that has dedicated acreage to the company's gathering systems defaults or exits -- the company's own filings note that customer non-performance can trigger termination rights or release dedicated acreage, which would remove volumes without a corresponding volume commitment ("minimum volume commitment") payment -- and the 2029 notes have to be refinanced into a much tighter high-yield market than exists today. One thing worth stating plainly, because it's a real and non-obvious part of the story: Summit Midstream has not paid a common dividend since May 2020, and its preferred stock dividend was itself suspended for a period, only resuming in February 2025. As of the end of 2025 it had $46.6 million of accrued, unpaid preferred dividends built up during that suspension, which the board approved paying in March 2026. There is no formal doubt-about-continuing-as-a-going-concern warning in the audited financial statements, and cash flow has been sufficient to fund the recent catch-up payment and operations. But this is a real history of a capital structure that has, in the recent past, been unable to service every layer of equity ahead of the common stock, and together with the concentrated 2029 debt maturity, it is the main reason the margin-of-safety price sits at a large discount to intrinsic value. The margin-of-safety price is $20 per share, well below even the bear-case estimate; from that price the bear case still implies a gain, and the base case implies a strong annual return if the business performs in line with it.
