Why Solaris Energy Infrastructure Is Back on Investor Radars

Solaris Energy Infrastructure (SEI) has drawn fresh attention after a subsidiary agreed to supply about 900 megawatts of power, equipment and long-term services under a 15-year contract with an existing industrial and technology client.

The latest contract comes amid a choppy but generally upward share price path. Solaris Energy Infrastructure is down about 7.5% on a 1-day share price return and 12.7% over 30 days, yet remains up 30.1% year to date and has delivered a 3-year total shareholder return of more than 7x. This suggests momentum that has cooled recently but remains significant over the longer term, as fresh long-term deals and a sizeable new fund investor influence how the market prices its risks and potential rewards.

Bulls view Solaris Energy Infrastructure as a discounted compounder following long-term power wins and fund backing. Bears see a hot stock cooling off. The valuation work indicates which argument the current price leans toward.

Most Popular Narrative: 35% Undervalued

Against a last close of $65.40, the most followed narrative pegs Solaris Energy Infrastructure's fair value near $101. This frames today’s pullback as a valuation gap driven by its contracted power pipeline and funded build out.

The main factor that has to go right is Solaris Energy Infrastructure successfully executing its capital intensive build out of more than 3.1 GW of secured and planned capacity, including integration of recent acquisitions and delivery of power and services projects described as high return, under increasing leverage.

Executing on a capital program funded by over $2.5b of issued notes, an undrawn $650m revolver and more than $800m of cash, alongside internal underwriting that targets unlevered returns above 20% on deployed capital, gives Solaris Energy Infrastructure a path to scale its contracted portfolio into a larger adjusted EBITDA contribution relative to current earnings.

See why 28 investors see Solaris Energy Infrastructure as 35% undervalued.

Result: Fair Value of $101.27 (UNDERVALUED)

Still, Solaris Energy Infrastructure relies heavily on rapid Power Solutions growth and a capital intensive build funded by over US$2.5b of notes. Any slowdown or higher financing drag could quickly challenge today’s upbeat narrative.

Another View: What Multiples Say About Solaris Energy Infrastructure

The first narrative leans on discounted cash flow and analyst targets to argue Solaris Energy Infrastructure looks cheap. Pricing on earnings tells a very different story. At a P/E of 81.2x versus an industry average of 24.6x and a fair ratio of 22.8x, the stock trades at more than triple the level the market could move toward, which raises the risk that sentiment rather than cash flow is doing most of the heavy lifting.
