Micron, a big chip maker, had a strong third quarter, beating expectations with its earnings and revenue.
But investors weren't happy when they saw Micron's forecast for the next quarter, which was just okay, not as good as they hoped.
Micron's stock dropped after hours because investors were worried about the company's future growth potential.
Micron is a big player in the artificial intelligence market, and they are hoping to capitalize on the growing demand for high-bandwidth memory chips.
