Aehr Test Systems (AEHR) is up 10.6% today. Here is some analysis on what might have caused this price movement. ([aehr.com](https://www.aehr.com/2026/06/aehr-receives-follow-on-order-from-major-silicon-photonics-customer-for-fully-automated-wafer-level-burn-in-system-for-hyperscale-data-center-optical-interconnect/))

Analysis: The most likely catalyst is a June 17 announcement that Aehr received a follow-on production order from a major silicon photonics customer tied to hyperscale data center optical interconnects. Investors also may be reacting to the implication of more orders ahead, since the customer provided a forecast for additional systems later this calendar year and Aehr had already highlighted strong bookings momentum and a path to significant fiscal 2027 growth.
