COHERENT CORP. vs TERADYNE, INC., two Scientific Instruments stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
Teradyne currently earns the margins Coherent is still assembling: a 36.9% operating margin on chip-test systems against a photonics maker whose bottom line keeps just 7.1% of revenue, with free cash slightly negative against its price. The market pays for the destination anyway, 180.1 times Coherent's thin earnings against 80.9 times Teradyne's strong ones, on the theory that optical transceivers for AI datacenters will transform the income statement faster than test demand can compound. Coherent's 3.1 current ratio and modest 0.29 leverage give it room to make the attempt. Teradyne is already there and priced accordingly; Coherent is priced for arrival before the trip is finished.
