Aehr Test Systems surged 15.95% in pre-market trading on Jan. 12, 2026, as investors reacted to strategic developments and sector momentum. The stock’s sharp advance followed a series of operational updates and market positioning moves that positioned the company to capitalize on demand in semiconductor testing solutions.

Analysts noted the move aligned with broader industry trends, including increased demand for advanced wafer-level testing technologies. Recent business decisions, including partnerships and product enhancements, were highlighted as catalysts for renewed investor confidence. The pre-market rally reflected optimism around the firm’s ability to scale its offerings in a competitive market landscape.
