A fast power pivot with real debt risk

01 Running thesis

Power growth, funded with debt

SEI is moving from oilfield logistics toward distributed power for big customers, especially data centers. The pivot is no longer just a plan. In Q1 2026, Solaris Power Solutions was 65% of revenue and 76% of segment adjusted EBITDA.

The bull case is simple: data centers need power faster than the grid can often provide it. SEI leases mobile natural-gas power systems under long-term contracts. Management says it now serves three investment-grade global technology companies, and total secured power generation capacity stands at 3.1 GW.

The story also changed because SEI added dealmaking to organic growth. The March 2026 Genco acquisition added 400 MW of power assets. The NovaLT16 turbine acquisition added rights to about 500 MW of future turbine supply, with deliveries scheduled from September 2026 to September 2029.

The bear case is that speed cuts both ways. SEI must integrate Genco, build large projects, manage suppliers, and fund heavy capital spending at the same time. The new $300M Bridge Term Loan, with an added $200M borrowing option, makes timing and cost control more important. The stock also needs a lot to go right, so the price question is real.

May 2026The Q1 2026 10-Q showed a bigger growth runway: Genco added 400 MW and the NovaLT16 deal added about 500 MW of future turbine supply. The same filing also raised financial risk through a new $300M Bridge Term Loan with a $200M added borrowing option.
Apr 2026Management said SEI added over 1 GW of new contracted power capacity with two new investment-grade technology customers. That reduced the single-customer concern, but shifted the main risk toward execution across many large projects.
Feb 2026The 2025 10-K confirmed the power pivot, with Solaris Power Solutions producing 68% of segment adjusted EBITDA for the full year. It also showed the old concentration problem, since one data center customer was 47% of consolidated revenue.
Feb 2026SEI announced a 10-year agreement for over 500 MW with a second major technology customer. That validated demand beyond the first anchor customer and improved visibility into future power revenue.
Nov 2025The Q3 2025 10-Q confirmed the same story: Power Solutions kept growing while the company targeted about 2,200 MW of power generation capacity by early 2028. Risk disclosures were not materially changed.
Nov 2025SEI raised its pro forma power generation target to about 2,200 MW and acquired HVMVLV to add in-house voltage distribution and regulation gear. The $748M convertible note financing also gave more flexibility for power expansion.
Aug 2025The Q2 2025 10-Q showed Power Solutions had become the main earnings driver, with more than two-thirds of segment adjusted EBITDA. It also said about 75% of the planned 1,700 MW fleet was committed under customer agreements.
Jul 2025Management raised adjusted EBITDA guidance for Q2 2025 and pointed to a path for pro forma adjusted EBITDA to exceed $1B annually. That gave investors a clearer target for the power strategy's possible earnings power.
02 Business model

Renting power where the grid is late

SEI makes money in two ways. The legacy Solaris Logistics Solutions segment provides mobile equipment and logistics for oil and gas well completions. That business can still generate cash, but it is no longer the main growth story.

Solaris Power Solutions leases configurable power packages. These use natural-gas turbines and related electrical gear to supply power at a customer site. This is often called behind-the-meter power, meaning the power is used on site before it goes through the utility grid.

The company is trying to win by locking up scarce equipment, signing long-term contracts, and offering more of the full power system. After the HVMVLV acquisition, SEI has more in-house voltage distribution and regulation equipment, which helps it provide a broader balance-of-plant package.

The model breaks if assets arrive late, costs rise, or customers slow their data center buildouts. SEI is also using joint ventures, such as Stateline, to share capital needs on large projects, while also buying assets directly through deals like Genco.

03 Product portfolio

What Solaris sells

Growth engine

Mobile gas turbine power rentals

SEI leases mobile turbine packages that run on natural gas and provide electric power for data centers, energy sites, and other industrial users. This is the core of Solaris Power Solutions.

Growth engine

Balance-of-plant equipment

These are the supporting electrical systems that make turbines useful at a customer site. SEI says newer contracts include broader project scope across this equipment and related services.

Steady

Specialty voltage distribution and regulation

The HVMVLV acquisition brought more electrical engineering and specialty voltage equipment in-house. That can make SEI a more complete power supplier instead of only a turbine lessor.

Option

Acquired Genco power assets

The Genco acquisition added 400 MW of distributed power generation assets. The open question is whether those acquired assets earn returns as attractive as SEI's organic projects.

Option

Stateline JV and large project development

SEI uses joint ventures for some large projects to reduce the capital burden. Stateline remains an important proof point for deployment and revenue start dates.

Cash cow

Oilfield logistics equipment

Solaris Logistics Solutions provides equipment and services for handling raw materials in oil and gas well completions. It is less exciting than power, but it can help fund the transition.

04 Business segments

Power now leads the mix

Solaris Power Solutions65%growing fast
Solaris Logistics Solutions35%flat

Segment shares use Q1 2026 revenue mix from the latest 10-Q: Power Solutions was 65% of total revenue, leaving 35% for Logistics Solutions. Power also supplied 76% of segment adjusted EBITDA, so the profit mix is even more tilted toward power.

05 Risk factors

What could break the story

Project delays across many sites

High impact · Medium odds

SEI is trying to deploy several large power projects at once, including Stateline. A delay can push revenue out while debt and equipment costs still need to be paid. This matters more now because the company has expanded capacity plans quickly.

We watchTrack announced in-service dates, Stateline revenue start, and management updates on deployment timing.

Genco integration risk

Medium impact · Medium odds

The Genco acquisition added 400 MW of assets, but the filing gives limited detail on customer terms and contract economics. If the acquired fleet needs more spending or earns lower returns than organic projects, the deal could dilute the growth story.

We watchWatch for disclosed Genco contract terms, utilization, margins, and any one-time integration costs.

Higher leverage and funding strain

High impact · Medium odds

SEI entered a $300M Bridge Term Loan in March 2026 and later added the ability to borrow another $200M. Debt can help fund growth, but it raises risk if turbines arrive late, customers delay projects, or capex runs over budget.

We watchMonitor total debt, bridge loan draws, interest expense, and updates on remaining 2026 capital spending.

Customer concentration

High impact · Medium odds

SEI has improved this risk by moving from one main data center customer toward three global technology customers. Still, the 2025 10-K said one data center customer was 47% of consolidated revenue and 88% of Power Solutions revenue for that year. A change in one large customer's plans could still hurt growth.

We watchTrack revenue by major customer, contract renewals, and whether new power awards keep broadening the customer base.

Supplier and tariff cost pressure

Medium impact · Medium odds

Power generation equipment has long lead times, and SEI relies on key suppliers for turbines and related gear. The NovaLT16 agreement helps secure supply, but tariffs or supplier delays could raise costs and slow project delivery.

We watchWatch turbine delivery updates, tariff disclosures, and any changes to expected project cost per MW.

Mobile Energy Rentals lawsuit

Medium impact · Low odds

SEI has previously disclosed a class action lawsuit tied to the Mobile Energy Rentals acquisition. Legal outcomes are hard to predict, and even a non-core lawsuit can create cost or distraction.

We watchCheck quarterly filings for changes in legal reserves, settlement talks, or court milestones.
06 Quick answers

In one breath

What does Solaris Energy Infrastructure do?

Solaris leases mobile power systems and provides oilfield logistics equipment. Its fastest growing business is Solaris Power Solutions, which supplies behind-the-meter power for data centers and other large sites.

Why are data centers important to SEI?

Data centers need huge amounts of reliable power, and grid connections can take time. SEI offers on-site power equipment under long-term contracts, which can help customers bring capacity online faster.

Why is SEI risky even though growth is strong?

The company is growing fast, buying assets, and taking on more debt at the same time. If project timing, Genco integration, or equipment costs go wrong, the financial pressure could rise quickly.

What should investors watch next?

Watch Genco integration, first NovaLT16 turbine deliveries, any draw on the extra $200M bridge loan capacity, and Stateline project revenue. These will show whether the growth plan is converting into cash flow.
