Sandisk Outlook Disappoints, Sending AI Memory Stocks Lower

Micron beat sales and profit forecasts for its latest quarter, driven by voracious demand from the AI boom, with guidance also strong except for margin comments on the earnings call that may have caused a muted market reaction. The memory chipmaker added about $43 billion in sales during the most recent quarter compared to the year-ago quarter, and more than $13 billion in sales from the quarter reported three months ago. Operating margins exploded in all business segments, exceeding 80% in some segments. Micron executives signaled tight capacity and higher prices for its products until 2028, with D.A. Davidson analyst Gil Luria saying expectations for tightening supply-demand conditions through both 2027 and 2028 meaningfully extend the industry's runway for strong pricing and earnings growth. The stock trades on a single-digit forward P/E ratio.

Micron CEO Sanjay Mehrotra said on the company's Q4 earnings call that physical AI, starting with self-driving cars and expanding to humanoid robots, could become a significant driver of memory and storage demand by the end of this decade. In its Q4 report on Wednesday, Micron reported earnings per share of $33.42, up 1,002% from $3.03 in the same quarter last year, while revenue climbed 379% to $54.23 billion from $11.31 billion in Q4 2025. Mehrotra said memory content in level 4 and higher autonomous vehicles typically exceeds 200 gigabytes, with storage reaching multiple terabytes, each more than an order of magnitude greater than in today's level two plus and level three semi-autonomous vehicles. He added that humanoid robots will have similar memory and storage requirements, which could serve as an additional revenue opportunity. Companies working on humanoid robots include Tesla, Figure, Hyundai's Boston Dynamics, Unitree Robotics, and Agility Robotics, though Reuters reported only 7,000 humanoid robots were sold globally in 2025 for industrial and professional services.
