AEHR will release its FY2026 Q4 earnings report after the market closes today. The market expects revenue of approximately $18.7 million, a quarter-over-quarter growth of about 81%, with Non-GAAP EPS close to breakeven. The options market is pricing in a post-earnings stock price fluctuation of around ±18%, indicating significant market disagreement over this report. AEHR operates upstream in this industry chain. Its equipment is responsible for Wafer-Level Burn-In (WLBI) testing of silicon photonics chips, screening out early failures before the chips are integrated into optical modules. Over the past few months, the company has consistently received additional orders from silicon photonics customers, with the latest two orders placed after the fiscal year ended. These will not be reflected in tonight's Q4 backlog. Four key points to watch tonight: 1. Whether silicon photonics customers reveal more expansion plans or announce new additional orders. 2. Whether demand for the FOX-XP automation system continues to grow, as this is tied to the pace of silicon photonics mass production. 3. The conversion of the $41 million AI testing equipment order backlog and the revenue realization timeline. 4. Whether the FY2027 guidance remains optimistic, especially management's outlook on AI, silicon photonics, and optical interconnect markets. While AEHR doesn’t directly represent the entire optical communications industry, it provides insight into whether silicon photonics mass production is still accelerating. If management continues to confirm customer expansions, additional orders, and production ramp-up, it will further validate the ongoing expansion trend in the industry chain. Combined with upcoming earnings reports from AAOI, Lumentum, Coherent, and others, the market will gain a more comprehensive view of demand in the AI optical communications industry chain.
