Interpretation of Aehr Test Systems' Sharp Decline on September 28

Keywords: High valuation correction, sector pressure, performance loss

1. On September 28, 2026, semiconductor and high-valuation tech stocks came under pressure, and the weakness in related sectors increased short-term correction pressure on AEHR.

2. On September 28, 2026, the company's cumulative gain for the year reached 380.29%. After a substantial rise at high levels, the stock price faces profit-taking and valuation adjustment pressure.

3. As of September 21, 2026, the company's forward price-to-sales ratio was about 18.59 times, significantly higher than the industry and comparable companies; as of May 29, 2026 for the 2026 fiscal year, revenue declined year-on-year by 15.2% and net loss was approximately 7.1 million USD. The top five customers contributed nearly 70% of sales, so the company’s fundamentals still face performance realization and customer concentration risks.
