Micron Technology Inc. (MU) shares took a hit Wednesday, trading lower in the hours before the memory chip maker was set to report first-quarter earnings. The pressure comes from a couple of developments rattling the AI chip sector more broadly.

What's Spooking Investors?

According to Reuters, Chinese scientists have built a prototype machine that can produce advanced semiconductor chips used in artificial intelligence. This marks potentially significant progress toward semiconductor self-sufficiency for China. The prototype generates extreme ultraviolet light, which happens to be critical technology currently dominated by Western suppliers.

Here's where it gets interesting: the machine was reportedly built by former ASML engineers who reverse-engineered extreme ultraviolet lithography systems. While the prototype hasn't actually produced working chips yet, its mere existence suggests China may be closer to developing advanced chipmaking capabilities than most people expected.

Adding to the sector-wide jitters, reports emerged that Blue Owl Capital won't be providing funding for a $10 billion deal to build Oracle's next data center. That's sparking investor caution across the AI sector Wednesday.

The Earnings Picture

Micron is scheduled to report earnings after the market close Wednesday. Analysts are estimating earnings per share of $3.95 and revenue of $12.83 billion.

The company has been on quite a roll. Last quarter, Micron reported earnings per share of $3.03, beating the consensus estimate of $2.86. Revenue came in at $11.31 billion, also topping the consensus estimate of $11.22 billion.

"In fiscal 2025, we achieved all-time highs across our data center business and are entering fiscal 2026 with strong momentum and our most competitive portfolio to date. As the only U.S.-based memory manufacturer, Micron is uniquely positioned to capitalize on the AI opportunity ahead," CEO Sanjay Mehrotra said last quarter.

Micron will look to extend its impressive streak of beating both earnings per share and revenue estimates, having exceeded expectations in seven consecutive quarters. The stock is up over 40% over the past three months, reflecting strong investor confidence in the AI memory chip story.

Analyst Optimism

Ahead of the earnings report, multiple analysts issued price target adjustments, all landing at the same $300 mark:

• Needham analyst N. Quinn Bolton maintained a Buy rating on Micron and raised the price target from $200 to $300.
• Wedbush analyst Matt Bryson maintained an Outperform rating on Micron and raised the price target from $220 to $300.
• Stifel analyst Brian Chin maintained a Buy rating on Micron and raised the price target from $195 to $300.
• Citigroup analyst Christopher Danely maintained a Buy rating on Micron and raised the price target from $275 to $300.

At the time of writing, Micron shares were trading 2.65% lower at $226.27.
