Solaris Energy Infrastructure valuation after Q1 2026

Why Solaris Energy Infrastructure is back in focus

Solaris Energy Infrastructure (NYSE: SEI) returned to the spotlight after reporting a strong first quarter of 2026 and announcing additional long-term contracted power capacity. The company’s update combined higher year-on-year sales, revenue and net income with raised earnings guidance and expansion of multi-year customer contracts. At the same time, the stock’s recent run-up has pushed valuation back to the centre of investor discussion. Some valuation approaches suggest the shares are only slightly above fair value, while a discounted cash flow (DCF) framework presented in the note implies a far larger upside.

Stock performance: strong medium-term momentum, mixed short-term moves

SEI shares have shown sharp momentum over longer windows, even as short-term moves have been less dramatic. One market snapshot cited a 1-day share price return of 2.04% and a relatively flat 7-day move. The same snapshot showed a 30-day return of 29.62% and a year-to-date gain of 43.91%.

In a separate trading update tied to the new contract news, the stock rose 4.2% on Tuesday and touched an intraday high of $11.24 before closing at $13.66. That report also stated SEI was up 54% in 2026, with 25% of the gain coming in April.

Q1 2026 results: revenue beat, EBITDA jump

Solaris reported Q1 2026 results on April 27, with revenue and earnings metrics broadly improving versus the prior year. Revenue for the quarter was $196.2 million, up 55% year-over-year and ahead of the $183.4 million consensus expectation cited. Earnings were 32 cents per share, up from 14 cents a year ago, but one cent below the 33-cent estimate.

Profitability, as measured by adjusted EBITDA, was approximately $14 million for the quarter. The company’s adjusted EBITDA was described as up 22% sequentially and 78% year-over-year. The company also disclosed adjusted EBITDA attributable to Solaris of approximately $16 million, excluding the EBITDA loss attributable to the non-controlling interest in Stateline Power, LLC.

Power Solutions segment: higher utilisation and sequential gains

The Power Solutions segment was highlighted as a key driver of sequential improvement. In Q1 2026, the business averaged around 910 MW of capacity earning revenue, compared with around 780 MW in Q4 2025, a 17% increase. Segment revenue was approximately $129 million, up 24% quarter-on-quarter.

Segment adjusted EBITDA was approximately $12 million, up 34% from Q4 2025, with the company attributing the increase primarily to higher activity. Separately, the note also stated the Power Solutions segment delivered sequential adjusted EBITDA growth of over 30%, supported by higher revenue from both owned assets and third-party leased capacity.

Long-term contracts: 600+ MW deal and more than 2 GW contracted

A major catalyst was the announcement of a third long-term power contract linked to data centre demand. On April 24, 2026, Solaris signed an agreement to provide over 600 MW of power capacity, including balance of plant, to a new customer affiliated with an “investment-grade, global technology company.” The contract runs for 10 years and includes an option to extend for an additional five years.

The company expects deployments to begin in late 2026 and scale through 2028. Solaris also stated it had signed two long-term contracts with investment-grade global technology customers totaling over 2 GW of contracted generation capacity, alongside associated balance-of-plant equipment.

Capacity expansion: 3.1 GW fleet and 900 MW additions planned

Solaris said it expanded generation capacity by more than 40% to 3.1 GW during the quarter, alongside closing two strategic transactions that supported the fleet increase. It also referenced previously announced incremental power generation capacity additions totaling 900 MW, with expected availability between 2026 and 2029, bringing pro forma generation capacity to 3,100 MW.

The Stateline joint venture was described as a project to provide approximately 900 MW of primary power to an artificial intelligence data centre, underlining the link between hyperscaler demand and Solaris’s project pipeline.

Guidance update: higher Q2 range, new Q3 range

Following the quarter, Solaris raised its Q2 adjusted EBITDA guidance by 10% to $13 million to $13 million. In another disclosure, the company described the prior Q2 guidance band as $16 million to $14 million. Solaris also introduced Q3 adjusted EBITDA guidance of $10 million to $15 million.

The note added that the Q3 midpoint trailed a Wall Street consensus of $100.5 million. Management linked guidance dynamics to the shift from temporary to permanent power at the Stateline JV and deliveries of new equipment.

Liquidity and balance sheet: cash, leverage and term loan expansion

Solaris’s liquidity metrics in the note were framed as supportive for ongoing buildout. Cash was stated at $153.3 million, and the current ratio was cited at 3.0x. Leverage was described as conservative, with a long-term debt-to-equity ratio of 0.32.

At the same time, the note flagged that balance-sheet scale expanded faster than earnings power, with total assets reaching $1,100 million and muted equity returns mentioned. On the funding side, Solaris upsized a term loan to allow for additional commitments of $100 million, taking total commitment to $100 million.

Valuation debate: “3% overvalued” narrative vs DCF upside

Two very different valuation signals were presented. A “most popular narrative” estimate placed fair value around $10.45, compared with a last close of $12.33, implying the stock was about 3% overvalued under that framework. The narrative was described as leaning heavily on growth in contracted power capacity and higher margins, while also noting execution risk if project timing slips, supply chain issues delay the 900 MW additions, or newer contracts ramp more slowly than expected.

In contrast, the DCF view cited suggested SEI at $12.33 was trading around 91% below an estimated future cash flow value of $129.20. The article framed this gap as a question of which signal investors trust more: near-term earnings multiples or longer-duration cash flow estimates.

Street view, dividend, and what investors are watching

Morgan Stanley maintained an Overweight rating and an $11 price target on SEI, according to the report. Analyst David Arcaro said the latest contract “strengthens” that stance. He estimated the 600 MW deal, assuming $100 per kilowatt, could create around $150 million in value, or roughly $1 per share.

Solaris also declared a quarterly dividend of $1.12 per share, payable on June 12 to holders of record as of June 2. Separately, the company was cited as being included among “7 Energy Stocks that Just Hit New All-Time Highs.”

Key numbers at a glance

Market impact and analysis: what the facts imply

The immediate market reaction combined contract momentum with a clear revenue beat, even though earnings per share missed by a penny. The 600+ MW agreement added another long-duration element to contracted visibility, and the company’s guidance update gave investors a new set of reference points for Q2 and Q3 profitability.

At the same time, valuation metrics and risk framing in the note show why the stock remains debated after a sharp run. SEI was stated to be trading at a P/E multiple of 99.48x, signalling that the market is already pricing in substantial growth. The “narrative” fair value framework suggested only modest overvaluation at recent prices, while the DCF estimate was dramatically higher. Investors, in turn, are likely to focus on execution: timing of the 900 MW additions, ramp pace of new contracts through 2028, and whether expanding assets translate into durable returns.

Conclusion

Solaris Energy Infrastructure’s Q1 2026 report combined fast year-on-year growth, higher adjusted EBITDA, expanded capacity to 3.1 GW, and another 600+ MW long-term data centre contract. The stock’s strong multi-month performance has pushed valuation into sharper focus, with the note presenting both a near-fair-value narrative estimate and an outsized DCF-based value estimate. Next catalysts include the start of power deployments in late 2026, scaling through 2028, and delivery against the company’s updated Q2 and new Q3 adjusted EBITDA guidance ranges.
