What this transaction means for investors
Aehr Test Systems founder and Board of Directors member Rhea Posedel’s April 22 sale of company stock is understandable given the massive increase in share price. The April 16 announcement of a record $41 million order from an AI hyperscale customer propelled shares to a 52-week high of $102.48 on April 24, just days after Posedel’s disposition.
Aehr’s solutions are seeing strong demand because of their application towards testing for artificial intelligence systems. This led to more than $37 million in quarterly bookings in its fiscal third quarter ended Feb. 27.
However, this has not translated into revenue growth yet. In fiscal Q3, sales totaled $10.3 million, down from $18.3 million in the prior year. Investors believe Aehr’s growth in orders will eventually translate into higher sales.
This positive investor outlook led to Aehr stock reaching a sky-high price-to-sales ratio of 64, a multi-year peak. Consequently, now is a good time to sell shares, but those interested in buying should wait for the stock price to drop first.
