    IDEX (IEX) Stock May Be 16% Undervalued As Guidance Rises

    Simply Wall St·09/29/2026 23:20:03
    Listen to the news

    IDEX Corporation has delivered strong share gains over the past year, which puts fresh attention on a simple question for investors paying today’s price. Do the company’s future cash flows support where the stock now trades, or has sentiment moved faster than the underlying economics of the business?

    • The stock is up 43.7% over the past year, which raises the stakes on whether cash generation can support that kind of rerating in the share price.
    • Management recently raised its full-year outlook and extended a long dividend track record, which can influence how investors think about the durability and timing of IDEX cash flows.
    • Prefer to judge IDEX on earnings? See why IDEX's 32.7x P/E tells a different valuation story.

    The issue now is whether the value implied by IDEX current share price lines up with what its cash flows suggest when run through a Discounted Cash Flow (DCF) lens.

    For context on whether IDEX’s 43.7% one year return and cash flow story align with what you see elsewhere, it can help to compare them with 31 high quality undervalued stocks.

    Is IDEX Still Cheap on Cash Flow?

    The Discounted Cash Flow (DCF) model here looks at what IDEX might deliver in future free cash to shareholders and then discounts those streams back to today. Over the last twelve months the group produced about $641.9 million in free cash flow, and the model assumes this pool of cash continues to grow rather than contract.

    Analyst and model estimates point to higher annual free cash flows by the early 2030s, with projected figures climbing into the low $1b range before discounting. On that set of assumptions, the DCF output sits meaningfully above the current share price of $230.43. Because management recently raised full year guidance and reaffirmed a long dividend streak, the described operational outlook is used to help explain why the cash flow based value still screens above where the market prices the stock today.
