Aehr Test Systems (AEHR 8.60%) stock surged higher by more than 14% as of 2:25 p.m. today. If you are wondering why the stock has performed so well recently (up 94% in 2026, as I write), it largely comes down to growing optimism (backed by evidence) that the company will fulfill the potential outlined in its earnings presentation in early January.
Aehr Test Systems pivots to the AI market
The company makes semiconductor test and burn-in solutions that semiconductor manufacturers rely on to ensure the quality, consistency, and reliability of their production. Its former core market was in Silicon Carbide (SiC) chips, whose main end market is electric vehicles (EVs). That market boomed with the rush to invest in EVs a few years ago, but has slowed as automakers have reset their expectations in a lower-than-expected growth environment for EVs.

Consequently, Aehr pivoted toward test systems for AI processors and secured an as-yet-unnamed lead customer described as "one of the premier large-scale data center hyperscalers that is developing its own AI processors and significantly expanding this capacity."
That said, the market always wants to see orders, not least as Aehr Test Systems is still loss-making.
Orders coming
Expectations of future orders were raised in the second quarter earnings presentation in early January when CEO Gayn Erickson told investors to expect bookings "between $60 million and $80 million" in the second half of its financial year, compared to just $6.2 million in the second quarter and $11.4 million in the first quarter.

Key Data Points
One month later, Aehr announced "an initial production purchase order from its lead production customer,"as its orders are starting to flow.
Given the recent commitments by hyperscalers to massively ramp spending, there's no indication of any slowdown in AI-related spending, and investors continue to price in the expectation that Aehr will achieve its goals. Throw in a stabilization in the EV market, and investors continue to bid the stock higher.
