Aehr Test Systems, founded in 1977 and headquartered in Fremont, California, is a specialized provider of mission-critical test and burn-in systems serving the global semiconductor industry. The company maintains a focused operational footprint with 138 employees while generating $50.9 million in trailing twelve-month revenue, reflecting its position as a niche supplier of high-value equipment to semiconductor manufacturers.

VP Alistair Sporck’s Aug. 10 sale of Aehr Test Systems stock occurred after shares attained a 484% one-year total return. It appears Sporck was capitalizing on the price increase to capture gains.
That said, the disposition only comprised a modest 3% of Sporck’s total equity position. Post-transaction holdings of over 27,000 suggest the insider maintains continued alignment with shareholder interests.
Aehr Test Systems is up thanks to an outstanding earnings report for its fiscal fourth quarter ended May 29. Revenue rose to $18.8 million, up from $14.1 million in the prior year. This demonstrates the growing customer demand the company is seeing for its semiconductor testing capabilities as a result of the rapidly expanding artificial intelligence sector.
Its growing revenue enabled the company to achieve fiscal Q4 net income of $1.4 million, an impressive reversal from the prior year’s net loss of $2.9 million. For its 2027 fiscal year, Aehr forecasted approximately 160% to 200% year-over-year sales growth. The astounding increase in net income and the next fiscal year’s revenue also contributed to the stock’s rise.
