Select Water Solutions (WTTR) Stock Could Be 40% Undervalued Despite Its $700 Million Acquisition

Simply Wall St·09/25/2026 12:23:05
Listen to the news

Select Water Solutions has seen a powerful multi‑year share price run, and the latest acquisition news has pushed the valuation debate squarely onto one issue: whether the current price is still grounded in the cash the business can generate over time.

  • Over the past 5 years, the stock has returned about 316.0%, which puts real pressure on the question of how much future cash flow is already reflected in today's US$19.53 share price.
  • The agreed US$700 million purchase of Pilot Water Solutions, largely funded with cash alongside stock, can reshape future cash generation by potentially increasing scale in water infrastructure while also committing the company to meaningful capital outlay and integration work.
  • What if you looked at Select Water Solutions through its earnings instead? See why Select Water Solutions's 78.7x P/E tells a different valuation story.

The issue now is whether that recent share price performance, combined with the Pilot Water deal, is justified by Select Water Solutions' intrinsic value based on its cash flows.

Is Select Water Solutions Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model here values Select Water Solutions on the cash it can return to shareholders over time. Latest twelve month free cash flow sits at about $10.4 million, yet the forecast path used in this DCF assumes that future cash generation grows into the low hundreds of millions of $ per year over the next decade rather than staying near recent levels.

Those projections build in a growing free cash flow profile instead of a flat or shrinking one, which is a key reason the DCF output comes in substantially above the current $19.53 share price. Because the agreed Pilot Water Solutions purchase is expected to lift EBITDA meaningfully by 2027, the deal helps explain why the model leans toward higher long term cash flows even though it also adds a large upfront cash commitment. That mix of richer projected cash generation and a price still below what the DCF supports is what the detailed valuation work is trying to capture.
