What has to go right for IDEX, and what could go wrong?

The investment turns on whether IDEX converts HST momentum into durable, cash-generating growth without losing the aftermarket or stretching the balance sheet.

How much cash does IDEX really make?

Net income measures accounting profit, while free cash flow measures cash generated after capital spending. A sale can count as income before the customer pays, and amortization can reduce profit without using cash in that period. In 2025, IDEX generated $680.4 million from operations and spent $63.6 million on capital equipment, leaving $616.8 million of free cash flow—more than reported net income.

IDEX defines free cash flow as operating cash flow less capital spending. An analyst might subtract the $27.3 million of stock-based compensation as an additional economic cost, producing $589.5 million of “real” free cash flow. That is not a second cash payment; it recognises the possible cost of dilution or share repurchases.

What this means. The company's own free cash flow matches ours, but our real free cash flow is lower because shares given to employees reduce what is left for shareholders.

What does an investor pay for IDEX today?

IDEX trades at $238.54 per share. That is 33.1x trailing earnings; the next-twelve-month multiple is 24.6x. Free-cash-flow yield is 3.5%, or 3.4% after stock pay.

IDEX’s calculated real free cash flow was 17.0% of revenue in 2025, and real free cash flow per share rose to $7.83 from $7.60.
