Solaris Energy Infrastructure (SEI) is back in focus after first quarter 2026 results showed higher sales, revenue, and net income versus a year earlier, along with raised earnings guidance and expanded long term power contracts.

SEI shares have cooled slightly after recent highs, with a 1 day share price return of 2.04% and a relatively flat 7 day move. However, the 30 day share price return of 29.62% and year to date gain of 43.91% suggest momentum has been strong, while the 1 year total shareholder return above 200% points to a very large payoff for long term holders.

With SEI posting rapid growth in sales and net income, a rising pipeline of long term power contracts, and a share price that has already delivered a very large 1 year return, is there still a buying opportunity here, or is the market already pricing in future growth?

Most Popular Narrative: 3% Overvalued

At a last close of $72.33 versus a narrative fair value of about $70.45, Solaris Energy Infrastructure is only slightly above that widely followed estimate, which leans heavily on growth in contracted power capacity and higher margins.

The accelerating demand for grid resiliency, electrification of industries, and AI-driven data center power needs is creating strong, ongoing demand for Solaris's modular, scalable power generation solutions, positioning the company for significant revenue growth as delivery of new capacity ramps through 2026 and beyond.

Want to see what kind of revenue climb and margin rebuild this story is built on? The narrative leans on compounding growth, richer profitability, and a very specific earnings profile by the end of the decade that is anything but conservative.

Result: Fair Value of $70.45 (OVERVALUED)

However, there is still meaningful execution risk if project timing slips or supply chain issues delay those 900 MW additions, and the newer contracts ramp more slowly than expected.

Another View: DCF Points to a Very Different Story

The consensus narrative prices Solaris Energy Infrastructure about 3% above a $70.45 fair value, yet our DCF model suggests something much more generous, with SEI at $72.33 trading around 91% below an estimated future cash flow value of $829.20.
