Tera Probe, Inc. (TSE: 6627), the Yokohama-based chip tester that checks wafers and finished processors before they ship, posted a 94% jump in operating profit for the six months to June 2026. The company attributes the surge primarily to testing demand for data-center processors, alongside contributions from a new customer's mass production and EV-related products.
Net sales for the half rose 44% year-on-year to ¥27.31bn, and operating profit rose to ¥7.21bn from ¥3.72bn, pushing the operating margin to 26.4% from 19.6% a year earlier. Net profit attributable to shareholders more than doubled to ¥2.72bn. Tera Probe attributes the swing to continued demand growth for data-center processor testing, the start of mass production for a new customer, and a modest lift from EV-related products. Automotive testing volumes held broadly steady, though results varied customer by customer.
The June quarter alone beat the company's own forecast: sales of ¥14.59bn ran 7% ahead of the ¥13.58bn Tera Probe had guided, and operating profit of ¥4.00bn came in 18% above the ¥3.39bn forecast. The company points to data-center processor production volumes running higher than planned and a weaker yen, it now assumes ¥160 to the dollar from August, as the reasons for the beat. Quarterly operating margin reached 27.4%, a record for the company, even after utility costs rose on summer peak electricity surcharges in Taiwan and depreciation increased from continued spending on advanced test equipment.
| Metric | 1H (to June) FY2025 | 1H (to June) FY2026 | FY2026 full-year guidance |
|---|---|---|---|
| Net sales | ¥19.02bn | ¥27.31bn | ¥59.10bn |
| Operating profit | ¥3.72bn | ¥7.21bn | ¥16.30bn |

Tera Probe now guides to record full-year levels: sales of ¥59.10bn, up 42%, and operating profit of ¥16.30bn, up 83%. To keep pace with data-center order flow, its Taiwan subsidiary, TeraPower Technology Inc., bought a new plant from DARWIN PRECISIONS CORPORATION, adding 8,328 square metres of land and 20,221 square metres of floor space near the Hsinchu and Taichung science parks, and separately leases additional production floor from Powertech Technology Inc. The Taiwan plant purchase alone accounted for about ¥8.6bn of the company's first-quarter capital spending.
Separately, Tera Probe will carry out a five-for-one stock split, with a record date of September 30, 2026 and an effective date of October 1. Shares outstanding will rise from 9,282,500 to 46,412,500, with the company's authorized share count moving to 150 million. Management frames the split as a liquidity and shareholder-base measure rather than a capital-raising step.
The results also update investors on the Kyushu plant, in Ashikita, Kumamoto, after the region's 2026 earthquake. The company says employees, on-site contractors and customers all evacuated safely with no injuries, and that its buildings and infrastructure escaped damage, aided by graded ground, an elevated 45-metre site and newer seismic-code construction. Some production equipment, tooling and product were damaged and are under repair, and the plant has been restarting output in stages since July 31. Tera Probe says it is still assessing the financial effect of the disruption.
