Aehr Test Systems' stock surged 6.05% during pre-market trading on Wednesday, continuing its positive momentum from the previous session.

The semiconductor testing equipment maker completed the sale of common shares for gross proceeds of approximately $60 million, according to regulatory filings. The successful capital raise appears to have generated positive investor sentiment, outweighing concerns about concurrent insider selling by company directors.

The offering was conducted under the company's effective registration statement and provides Aehr Test Systems with significant capital for its operations and growth initiatives.
