Business Overview: Stabilis Solutions, Inc. (NASDAQ: SLNG)

---

Executive Summary

Stabilis Solutions, Inc. is a small-cap energy transition company that produces, stores, transports, and delivers liquefied natural gas (LNG) to customers who lack pipeline access or need a cleaner, more flexible fuel than diesel or propane. Incorporated in Florida and headquartered in Houston, Texas, Stabilis has more than two decades of operating history and has delivered over 530 million gallons of LNG through more than 55,000 truck deliveries since inception.

Stabilis is not a large-scale LNG exporter in the mold of the multi-million-gallon-per-day terminals built by the major oil and gas majors. It is instead a niche, small-scale "LNG-as-a-service" provider — it liquefies and moves gas in volumes that larger players generally ignore, serving marine bunkering, remote power generation, aerospace (including a direct relationship with SpaceX), mining, and industrial customers. It matters because it sits at the intersection of two growing themes — the marine industry's shift away from heavy fuel oil, and surging behind-the-meter power demand from data centers and other remote loads — while holding one of the relatively few active U.S. Department of Energy (DOE) LNG export authorizations in its weight class.

The business swung from net income of $4.6 million in 2024 to a small net loss in 2025 as two large multi-year contracts (a marine bunkering agreement and a Louisiana remote-power contract) concluded in the fourth quarter, but the company has since signed a roughly $200 million multi-year take-or-pay supply agreement tied to behind-the-meter power generation, expected to ramp starting in early 2027.

1. Core Business Model & How They Work

Stabilis generates revenue from three related streams built around physically moving natural gas from the pipeline grid into a liquid, transportable form and delivering it to customers who cannot otherwise get it.

[ Pipeline Natural Gas ] ➡️ [ Liquefaction (owned plants + ~31 third-party sources) ] ➡️ [ Cryogenic Storage & Trucking ] ➡️ [ End Customer Fueling / Power Generation ]
                                                                 │
                                                                 ├──► LNG Product Sales (commodity + logistics margin)
                                                                 ├──► Cryogenic Equipment Rental (170+ mobile storage/vaporization units)
                                                                 └──► Engineering & Field Support Services

1. LNG Production and Sourcing: Stabilis owns a liquefier in George West, Texas (up to 100,000 LNG gallons/day) and one in Port Allen, Louisiana (up to 30,000 gallons/day), and supplements its own output by purchasing from roughly 31 third-party LNG production sources across North America, giving it a flexible, asset-light supply network layered on top of owned capacity.
2. Rental Fleet: A fleet of more than 170 mobile cryogenic storage and vaporization units is rented to customers who need on-site LNG storage and regasification, generating a recurring, less commodity-sensitive revenue stream.
3. Services: Engineering and field support help customers design and operate LNG-fueled or LNG-powered systems, deepening the customer relationship beyond a simple fuel sale.
4. Regulatory Moat: A DOE authorization (received in 2022, with roughly 25 years remaining on its 28-year term) permits export of up to 51.75 Bcf/year (~1.0 MTPA) of U.S. LNG to both free-trade and non-free-trade countries — exports to non-FTA countries began in Q3 2024, including deliveries to Europe.
5. Growth Project: A proposed 350,000 gallon/day liquefaction and bunkering facility in Galveston, Texas is in development, with a Final Investment Decision targeted for around Q1 2026.

3. Competitive Landscape

Stabilis does not primarily compete against other LNG liquefiers — it competes against the substitute fuels that customers would otherwise use where pipeline gas isn't available.

                 SCALE OF LIQUEFACTION CAPACITY
                 Small (<~100k gal/day)         Large (multi-million gal/day)
              ┌───────────────────────────┬───────────────────────────────┐
  High        │                           │                                │

              └───────────────────────────┴───────────────────────────────┘

• Distillate fuels (diesel, marine gas oil) and propane: The largest competitive threat by volume — these are the incumbent fuels Stabilis is trying to displace, and they remain cheaper to access in many locations even if dirtier.
• Pipeline natural gas and CNG: Compete where pipeline infrastructure exists; Stabilis's value proposition is specifically for locations pipelines don't reach.
• Utilities: Some utilities offer competing fuel-delivery solutions with a lower cost of capital and long-standing customer relationships, a structural disadvantage for a company of Stabilis's size.
• Large-scale/world-scale liquefiers: The company states it does not believe it competes with liquefiers producing more than 1.7 million gallons/day — those players serve bulk marine export and pipeline-scale markets, a different part of the LNG value chain entirely.

4. Strategic Strengths & Risks

Strengths (The Moat)

• DOE Export Authorization: A 28-year license (roughly 25 years remaining) to export up to 51.75 Bcf/year to FTA and non-FTA countries is a real, hard-to-obtain regulatory asset that few small-scale LNG players hold.
• Niche Positioning: By operating below the scale threshold of major liquefiers, Stabilis avoids head-to-head competition with oil and gas majors while still serving real, growing demand (marine bunkering, remote/behind-the-meter power, aerospace).
• Data Center Power Tailwind: Management cites active discussions with data center customers needing fast, flexible behind-the-meter power — a new demand source layered on top of legacy marine and industrial markets.

Risks

• Customer Concentration: In 2025, Carnival Corporation, Aggreko Plc, and SpaceX each accounted for more than 10% of revenue, and two large multi-year contracts (marine bunkering ~32% of 2025 revenue; Louisiana remote power ~19%) both concluded in Q4 2025, directly causing the swing from net income to a net loss.
• Commodity Exposure: Revenue is tied to natural gas prices relative to diesel and propane; a narrowing price advantage reduces the economic case for switching to LNG.
• Small Scale vs. Capital-Intensive Growth: The Galveston expansion requires project financing and a Final Investment Decision that has not yet been reached; execution risk is real for a company of Stabilis's size.
• Competitive Disadvantage vs. Utilities: Some incumbent competitors have structurally lower costs of capital and longer customer relationships.

6. Summary Conclusion

Stabilis Solutions operates a capital-light, niche LNG logistics business that profits from the gap between pipeline-connected markets and the many customers — marine vessels, remote power sites, aerospace launch operations, mines — that pipelines don't reach. Its moat is modest but real: a long-dated DOE export license, an asset base too small to interest the major liquefiers, and growing relationships with large, credit-worthy customers in structurally growing end markets like marine decarbonization and data-center power.

The company's near-term story is a transition: two legacy contracts that drove 2025 results rolled off just as a new, larger take-or-pay agreement and the proposed Galveston facility move toward reality. Whether Stabilis converts its current data-center and marine-bunkering pipeline into contracted, recurring revenue before its existing book shrinks further is the single biggest swing factor for the business over the next two years.
