Based on the last 12 months of reports, through 31 March 2026
The sector median covers every company in the sector on the US market, loss-making ones included.
Teradyne makes the machines that test finished chips before they ship.
Every chip is tested before sale: does it run at the rated frequency, is any block defective. A tester costs millions, is bought by manufacturers and assembly houses, and demand for it is set not by phones sold but by fabs' decisions to expand capacity. Hence cyclicality sharper than that of chips themselves.
Test complexity grows faster than chip complexity: a processor with dozens of cores and integrated memory has disproportionately more states to verify. That is a structural tailwind. The second line is industrial robots for assembly lines, a separate and still small market. The company pays a dividend and buys back stock.
