Trio-Tech's burn-in board orders keep accelerating, with another order for next-generation boards, and it ranks among the highest-conviction micro-caps to hold long term. Per @ren_stocks, it has won over $5 million of burn-in board orders this quarter, including $2.6 million for a next-generation AI GPU platform, on top of $5.3 million in March. Every AI GPU and CPU must pass burn-in testing before shipping; last quarter revenue rose 124% and back-end solutions 141%. x.comÂ
Trio-Tech has become a critical testing supplier for AI and 800V hardware: its Q3 FY2026 revenue rose 124% to $16.51M, with semiconductor back-end revenue up 141% and now about 80% of sales, driven by burn-in testing of packaged chips. Gross margin fell to 16% from 27% on high-volume contracts and ramp costs, which looks temporary, and the net loss narrowed to $38k. A new 104,000 sq ft Penang lab near AMD, Intel and Broadcom roughly doubles capacity, and in-house equipment cuts capex. x.comÂ
Trio-Tech's burn-in board orders keep accelerating because every AI GPU and CPU must pass burn-in testing before it ships. It announced another $2.6 million of orders for boards supporting a next-generation AI GPU platform, lifting this quarter's total above $5 million on top of $5.3 million in March. Last quarter's revenue rose 124% year over year, and a new 104,000 sq ft lease in Penang points to a multi-year ramp. Gross margins remain under pressure as it scales. x.comÂ
Trio-Tech's second order for the same next-gen AI GPU platform shows the customer's production ramp is real. A $2.6 million order follows $5.3 million in March, about $8 million for one program, and customers don't reorder if the first batch failed. Every AI GPU must be burned in under extreme heat, voltage and load before shipping, making its burn-in boards a quiet, mandatory chokepoint. The roughly $160 million micro-cap doubled nine-month revenue to $48 million and is expanding in Malaysia. … Show more
Trio-Tech's bear case has been validated: growth is slowing and margins are bad. The stock fell 30% on the quarter, which @JonkooTrades, a bull who admits defeats publicly, said he could not explain. x.comÂ
Trio-Tech is a high-conviction, high-risk asymmetric bet on burn-in testing demand for AI chips. Q3 revenue rose 124% to $16.5 million, new orders of $5.3 million and $2.6 million cover burn-in boards for next-gen AI GPUs, and a $10 million raise funds a Malaysia facility. At about $160 million it trades far below peers, with trailing EPS now positive. Risks: gross margin fell to 16% from 27%, dilution, insider selling, a run from $2.45 to $21.38 then a sharp pullback, and thin liquidity. x.comÂ
Trio-Tech is a risky but compelling micro-cap sitting in the middle of a burn-in testing bottleneck. Growth is huge year over year, potential new customers include Micron, and CPU demand should soar in the inference era while Trio-Tech handles burn-in testing for AMD. Real estate is roughly 10% of its market cap, and the multiple looks ridiculous if execution continues. @JonkooTrades notes Zacks just initiated the first Wall Street coverage, at Neutral, citing AI burn-in orders. x.comÂ
Trio-Tech's business looks misaligned with what the market needs. It sells burn-in boards that customers can design out quite easily, and Aehr Test Systems could build a competing segment fairly quickly. It is also heavily concentrated in one customer, risky for such a small company; Aehr is concentrated too, but its customers keep coming back for more. x.comÂ
Burn-in test is one of three areas set to run hot into the summer, alongside CPU ecosystem names and power semis, driven by the Rubin ramp and the CPU production ramp. Trio-Tech and inTEST are among the undervalued names with immediate upside. inTEST has a third tailwind from the scale-up of power semis. Capital should shift from photonics and connectivity toward these areas. Barring a prolonged Strait of Hormuz closure, other headwinds such as private credit shouldn't hit until Q3 or later. … Show more
Aehr Test Systems is the cleaner AI burn-in play, with a structural edge in wafer-level burn-in that nobody else has and a $41M single order from a hyperscaler in April. Its roughly 25x premium to Trio-Tech reflects equipment margins and that moat, not mispricing. Trio-Tech grew revenue 69% but its services margin fell to about 16% as low-margin AI testing grew, and it raised equity 30-40% below market, so at $13 it looks fairly priced. x.comÂ
Trio-Tech's gross margins are deteriorating because its testing revenue carries lower margins than its legacy segments. @yianisz counters that Trio-Tech still looks obvious and its margins will recover over the next 2-3 quarters. x.com x.comÂ
Aehr Test Systems' lead hyperscale customer is expanding production with about $6M of follow-on Sonoma orders for a second-generation AI processor. These are production-capacity orders, not evaluations, and the customer expects the second processor eventually to exceed the volumes of the first, already in high-volume production. Teradyne's new burn-in on Titan HP overlaps only with package-level Sonoma work, not FOX-XP wafer-level burn-in that screens dies before costly CoWoS packaging. x.comÂ
