Approach 1: Solaris Energy Infrastructure Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes expected future cash flows and discounts them back to what they could be worth in today’s dollars. It is essentially asking what all the future cash that Solaris Energy Infrastructure might generate is worth right now.

For Solaris Energy Infrastructure, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is a loss of about $246.6 million. Analyst and model projections then step through the next decade, with estimated free cash flow of $435.5 million in 2028 and further annual figures out to 2035, all in $. Simply Wall St extrapolates beyond the first few analyst covered years to build this longer path of cash flows.

Discounting those projected cash flows back to today results in an estimated intrinsic value of about $474.48 per share. Compared with the recent share price of $55.35, the DCF output implies the stock trades at an 88.3% discount to that estimate. This indicates that Solaris Energy Infrastructure appears materially undervalued on this cash flow view alone.

Approach 2: Solaris Energy Infrastructure Price vs Earnings

For a profitable company, the P/E ratio is a useful way to think about what you are paying for each dollar of current earnings, which helps compare businesses of different sizes. A higher or lower P/E often reflects what the market is willing to pay given expectations for earnings growth and the perceived risk of those earnings, so a company with faster expected growth or more resilient cash flows might reasonably trade on a higher multiple than one with weaker prospects or higher uncertainty.

Solaris Energy Infrastructure currently trades on a P/E of 101.70x. That sits above the Energy Services industry average P/E of 26.94x and also above the peer group average of 20.01x. Simply Wall St’s Fair Ratio framework goes a step further by estimating what a more tailored multiple could look like, based on factors such as earnings growth, profit margins, industry, market cap and specific risks. For Solaris Energy Infrastructure, this Fair Ratio is 22.01x, which is meaningfully below the current P/E of 101.70x, suggesting the shares look expensive on this metric alone.

Result: OVERVALUED
