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

A Discounted Cash Flow, or DCF, model estimates what a business might be worth by projecting its future cash flows and discounting them back to today using a required rate of return. It focuses on the cash that could, in theory, be returned to shareholders over time.

For Solaris Energy Infrastructure, the 2 Stage Free Cash Flow to Equity model starts from last twelve month free cash flow of a loss of $246.60 million. Analyst and extrapolated projections in the model move from an estimated free cash flow of $494.10 million in 2026, to $354.00 million in 2028, and up to $1.56b by 2035. All cash flows are assessed in US$, and anything beyond the explicit analyst window is extrapolated by Simply Wall St based on the earlier years.

When all those projected cash flows are discounted back to today, the model arrives at an estimated intrinsic value of about $338.73 per share. Compared with the recent share price of $57.83, this implies the stock is assessed as 82.9% undervalued under this DCF framework.

Approach 2: Solaris Energy Infrastructure Price vs Earnings

For profitable companies, the P/E ratio is often a practical way to think about value because it directly links what you pay for each share to the earnings that support it. A higher P/E can reflect stronger growth expectations or lower perceived risk, while a lower P/E can point to lower growth expectations or higher perceived risk.

Solaris Energy Infrastructure is trading on a P/E of 106.25x. That sits well above the Energy Services industry average P/E of 29.54x and the peer group average of 33.97x. On simple comparisons, the stock carries a much richer earnings multiple than both its sector and its immediate peers.

Simply Wall St’s Fair Ratio for Solaris Energy Infrastructure is 25.06x. This is a proprietary estimate of what a more “normal” P/E might look like, after considering factors such as the company’s earnings growth profile, industry, profit margins, market cap and specific risks. Because it blends these elements into a single yardstick, the Fair Ratio can be more informative than looking only at peer or industry averages that do not account for company specific characteristics. Comparing the current 106.25x P/E with the Fair Ratio of 25.06x suggests the shares are trading above what this framework would view as a more balanced level.

Result: OVERVALUED
