Result: Fair Value of $89.73 (UNDERVALUED)

However, Solaris Energy Infrastructure's story could be tested if current demand proves more one off than recurring, or if major data center contracts slip or scale back.

Another View: Solaris Energy Infrastructure Through the P/E Lens

The narrative and DCF style work suggest Solaris Energy Infrastructure is trading well below an estimated fair value, but the simple earnings multiple tells a very different story. SEI trades on a 108.7x P/E versus 26.4x for the US Energy Services industry, 46.8x for peers, and a fair ratio of 46.6x. That gap implies meaningful valuation risk if expectations cool, so which signal do you trust more?
