We publish no single base value for IDEX Corporation. Our valuation methods put it between $178.00 and $189.48 a share. The valuation code's reason: no point fair value: the two anchors behind it compound the same growth rate and differ only in how they end — a perpetuity at the terminal rate against a multiple on the final year — so the midpoint between them measures terminal treatment rather than what the business is worth. The published range is the same reading with the false precision removed: read it as the span the method supports, and treat neither edge as a point estimate.
| Method | Value | vs price | Basis |

| Discounted cash flow | $178.00 | -25.2% | free cash flow $667.10m, growth 6.93% for 5 years, then fading to 3% over 5 more, discounted at 9.59%; stress floor $111.03 |
| Exit multiple (P/E) | $189.48 | -20.4% | earnings per share $8.95 valued at 26× (the stock's own median P/E) in 5 years, discounted back |

Each working is rebuilt by code from the valuation's own figures and checked against the published value.
The discount rate:
| Risk-free rate | 5.13% (10-year US Treasury yield) |
| Company's own beta | 0.95 (5 years of monthly returns against the S&P 500; standard error 0.15) |
| Peer beta | 1.00 (median of 13 S&P 500 Industrial Machinery & Supplies & Components companies) |
| Blend of own and peers | 0.98 (42% own, 58% peers, weighted by how precisely the company's own beta is measured) |
| Adjusted beta | 0.99 (0.67 × 0.98 + 0.33, pulled toward the market's 1.0) |
| Equity risk premium | 4.5% |
| Discount rate = risk-free + adjusted beta × premium | 9.59% |
Free cash flow grows 6.93% a year for 5 years, then fades in equal steps toward 3% over 5 more; each year is discounted by 1 ÷ (1 + rate)^year:

One-year price simulation: a 10% chance the price is below $190.86 and a 10% chance it is above $340.59 in a year; a 62% chance it is higher than today's $238.03, from 22.48% volatility. The simulation assumes the price drifts up at our discount rate of 9.59% a year.
At $238.03 the price implies free cash flow growing 11.9% a year for five years and then fading toward 3% over five more; its revenue has grown 6.9%.
