Aehr Test Systems saw its shares rise 8.7% in pre-open trading following disclosure of a follow-on production order for a FOX-XP wafer-level burn-in system from a major global networking products company that is a key supplier to the data center optical transceiver market.
The ordered FOX-XP system is set up to handle nine wafers at once and is supplied with a fully integrated WaferPak Auto Aligner plus a complete suite of FOX WaferPak Contactors. Aehr said delivery of the system is scheduled to occur within the next six months.
This purchase is a direct follow-on to an initial order placed earlier in 2026. At the time of the first purchase, the customer had indicated the possibility of buying additional systems as it increased capacity to support next-generation hyperscale data center deployments. The recent confirmation of repeat business reinforces the developing commercial relationship between Aehr and the customer and provides evidence that the customer's silicon photonics-based transceiver production volumes are expanding.
Investors have habitually responded positively to news that points to rising production volumes for customers in this segment, and that dynamic was evident in today’s premarket movement for Aehr stock. The company-specific catalyst was sufficiently strong to push the share price higher despite a cautious tone across parts of the broader market.
Market context for the move included a generally firmer premarket tape: Nasdaq 100 Futures were up 0.6% and S&P 500 Futures were up 0.1% following a broad semiconductor selloff the previous session, while Dow Jones Futures were relatively flat. Market attention was also concentrated on the Federal Reserve’s June 16-17 Federal Open Market Committee meeting. Market participants were largely expecting no change to the federal funds rate target range of 3.50% to 3.75%, although the debut press conference by new Fed Chair Kevin Warsh introduced an element of uncertainty into the immediate macro outlook.
Taken together, the tangible, revenue-generating nature of the follow-on order from a production customer in the high-growth silicon photonics space supplied a clear, company-level reason for the stock’s rise. During the session the stock reached a high of $118.69 and was trading within striking distance of its 52-week high of $126.62.
