Most Popular Narrative: 13.7% Undervalued

Based on the most followed narrative, IDEX's fair value of $237.71 sits above the last close at $205.15, putting the spotlight on what is driving that gap.

The recent acquisition of Mott and its integration into IDEX's existing business operations are anticipated to enrich the company's capabilities and revenue streams. Mott's agreements, such as the $40 million multiyear wastewater filtration project, are expected to contribute positively to earnings.

Analysts are tying this valuation to a structured path for higher revenue, thicker profit margins, and a future earnings base that looks meaningfully different from today. The fair value hinges on how those pieces connect over time, not just on the current share price. If you want to see exactly which growth and margin assumptions carry the most weight, the full narrative lays them out step by step.

However, this depends on tariffs not eroding margins, as well as sector softness in areas like semiconductors and agriculture not spilling into broader and more uneven demand.

Another angle on valuation: what the P/E ratio says

While the narrative and fair value estimate point to upside, the current P/E of 29.9x paints a different picture. It sits above the US Machinery industry at 26.1x, the peer average at 22.6x, and even the fair ratio estimate of 26.4x. This implies less margin for error if growth or margins disappoint.
