Why is a raise in a business worth under 2% of revenue read as a signal for the shift to optics?

FormFactor, a semiconductor test company, raised its outlook for co-packaged optics (CPO) revenue this year. It said it will pass the $10 million to $20 million range it set out at the start of the year by the end of the third quarter, and significantly exceed $20 million for the year as a whole.

FormFactor, Inc. Reports 2026 Second Quarter Results (GlobeNewswire, 2026-07-29)

That release put second quarter revenue at $258.2 million, a record and 31.9% higher than a year ago. The company said demand for HBM and CPO pushed up revenue in both the Probe Cards and the Systems segments.

What this company actually sells

FormFactor does not sell chips. It sells the equipment that tests them. Before a freshly made chip is cut out of the wafer, electrical signals are pushed through it to catch defects, and the plate that lands needles on the tiny contact pads to do that is a probe card. Think of it as a stamping bench that checks each chip one at a time.

Why it shows up at a test company first

Test equipment is bought before volume production arrives. Once the chip to be built is settled, the test line has to be laid first, so revenue at the equipment company moves ahead of revenue at the optical component makers.

On the call, chief executive Mike Slessor gave two reasons for the acceleration. The volumes of CPO chips planned for later this year, and the company's lead in the first test insertion. In the same session he said the world's leading foundry was again a customer worth more than 10% of revenue.

The number is still small

Equipment revenue rose, but the CPO share inside it is still small.

The timeline has not been pulled in

Management was clear that adoption itself has not moved earlier. It described acceleration in the very short term while saying there is no significant pull-in of the roadmap.

Facing the same acceleration, one side reads an earlier adoption date, the other reads a preparation stage moving first.

So what will settle it

The question comes down to one thing. Does demand that appeared first in test equipment turn into real volume. If CPO revenue clears the $20 million range inside the third quarter, the planned chip volumes actually arrived. If it does not, only the test line was laid early, and revenue at the optical component makers has to wait longer. Sending signals down copper is running into physical limits in speed, heat and power. The attempt to get past those limits with light is now printing as a number in a test equipment company's results. The point of this card is the order of events, not the size.
