Aehr Test Systems' stock surged 5.10% during Tuesday's trading session, reflecting positive investor sentiment following a significant corporate action.

The semiconductor testing equipment maker completed the sale of common shares for gross proceeds of approximately $60 million, according to a regulatory filing. The offering was conducted under the company's effective registration statement, which had previously registered up to $100 million of securities.

Separately, company director Scott Geoffrey Gates reported dispositions of 60,000 common shares at prices ranging from $91 to $95 per share on the same day. The successful capital raise appears to have outweighed any concerns about insider selling, driving the stock's upward movement.
