    IDEX (IEX): A Fresh Look at Valuation After Recent Share Price Rebound

    Simply Wall St·12/17/2025 12:19:54
    Listen to the news

    IDEX (IEX) has quietly climbed about 11% over the past 3 months, even as its year to date and 1 year returns remain negative. That mix of recovery and lag is drawing fresh attention.

    See our latest analysis for IDEX.

    Zooming out, that 30 day 7.7% share price return sits alongside a weak year to date share price performance and a negative one year total shareholder return. This suggests recent momentum is rebuilding as investors reassess IDEX’s growth and risk profile.

    If IDEX’s rebound has you rethinking your watchlist, this could be a good moment to scout other industrial names through aerospace and defense stocks as potential additions.

    With earnings still growing and the share price trading below many analyst and intrinsic value estimates, investors now face a key question: is IDEX quietly undervalued, or is the market already pricing in its future growth?

    Most Popular Narrative Narrative: 9% Undervalued

    With IDEX closing at $177.19 versus a narrative fair value around the high $190s, the story hinges on how fast earnings and margins can compound.

    Analysts expect earnings to reach $698.2 million (and earnings per share of $9.41) by about September 2028, up from $469.4 million today.

    In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 25.8x on those 2028 earnings, down from 26.0x today.

    Read the complete narrative.

    Curious what kind of revenue climb, margin lift, and valuation reset are baked into that outlook? The narrative leans on ambitious compounding and a premium future multiple. Want to see exactly how those moving parts add up to the suggested fair value?

    Result: Fair Value of $194.62 (UNDERVALUED)

    However, rising tariffs and sector specific softness in semiconductors and agriculture could squeeze margins and unsettle the growth story that investors are buying into.

    Another View: Multiples Flash a Caution Light

    While narrative fair value and our model point to upside, the current price implies a price to earnings ratio of 27.7x, richer than both peers at 24.3x and a fair ratio of 25.1x. That premium narrows the margin of safety, so consider how comfortable you are paying up for quality here.
