What Happened?
Shares of semiconductor equipment provider Amtech Systems (NASDAQ: ASYS) plunged after the company reported mixed results for the fourth quarter of 2025, where a significant earnings miss overshadowed revenue that was in line with expectations.
Adjusted earnings per share came in at $0.03, which was 57.1% below analysts' consensus estimates of $0.07. While revenue for the quarter fell 22.2% year-on-year to $18.97 million, this figure met Wall Street’s forecasts. Investors were also likely concerned by the increase in inventory days outstanding, which suggested weakening demand. Even a stronger-than-expected revenue forecast for the next quarter was not enough to offset the concerns over the company's declining profitability.

What Is The Market Telling Us
Amtech’s shares are extremely volatile and have had 55 moves greater than 5% over the last year. But moves this big are rare even for Amtech and indicate this news significantly impacted the market’s perception of the business.
The previous big move we wrote about was 2 days ago when the stock dropped 10% on the news that uncertainty increased over when key companies can resume large-scale sales of high-end artificial-intelligence chips to China. The U.S. government reportedly extended its review of export license applications for AI hardware, such as Nvidia's H200 chips, on national security grounds. This delay created uncertainty for chipmakers and reportedly led some Chinese customers to postpone orders until clearer guidance was issued. While there were earlier signals that some shipments could restart, the extended review process stalled progress, weighing on the stock of major exporters who saw China as a significant market. The situation highlighted the ongoing geopolitical tensions impacting the semiconductor industry's global supply chain.
Amtech is down 16.9% since the beginning of the year, and at $10.76 per share, it is trading 41.2% below its 52-week high of $18.28 from January 2026. Investors who bought $1,000 worth of Amtech’s shares 5 years ago would now be looking at an investment worth $1,284.
