BlackRock Inc. and Algert Global LLC established significant new positions in Aehr Test Systems. BlackRock purchased nearly 2.66 million shares valued at approximately $255.48 million. This investment grants BlackRock an 8.15% stake in the semiconductor equipment firm.

Algert Global acquired over 82,000 shares valued at roughly $7.9 million. These moves follow a period of strong order bookings and positive analyst ratings for the company.

The investments signal institutional confidence in Aehr’s expansion into the artificial intelligence and silicon photonics markets. However, regulatory filings also show the company’s CEO and COO sold shares earlier in August.
