Micron (MU) Stock Skyrockets 10% After Obliterating Earnings Expectations by a Staggering 75%

Micron just delivered a financial knockout punch that sent its stock soaring.

The Numbers Don't Lie

Forget beating estimates—Micron demolished them. The chipmaker's latest earnings report didn't just clear the bar; it launched the bar into orbit, surpassing Wall Street's forecasts by a colossal 75%. The market's reaction was immediate and explosive, propelling MU shares up 10% in a single session. That's the kind of performance that turns skeptical analysts into believers and sends short-sellers scrambling for cover.

A Signal in the Silicon

This isn't just a win for one company; it's a flashing indicator for the entire tech hardware and semiconductor ecosystem. When a memory and storage giant crushes numbers this hard, it speaks to underlying demand that the broader market might be underestimating. It highlights the relentless, data-hungry engines of AI, cloud computing, and next-gen devices—trends that aren't slowing down anytime soon.

While traditional finance scrambles to adjust its spreadsheets, one can't help but marvel at the sheer velocity of value creation in tech—a stark contrast to the glacial pace of innovation in some legacy sectors. Micron's surge is a reminder: in the modern economy, the most valuable real estate isn't on Wall Street; it's on a silicon wafer.

The stock responded accordingly. Shares climbed nearly 10% in premarket trading Thursday. Year-to-date, the stock has gained 168%.

The blowout numbers stem from a simple supply-demand equation. Memory chip prices are soaring. Supplies remain tight while AI data centers gobble up everything available.

Micron Technology, Inc., MU

Micron is one of only three major suppliers of high-bandwidth memory chips. These specialized components are essential for training and deploying AI models. The other two players are South Korea’s SK Hynix and Samsung Electronics.

CEO Sanjay Mehrotra told investors the company expects memory markets to stay tight past 2026. That’s a long runway of constrained supply.

Customers Can’t Get What They Need

Chief Business Officer Sumit Sadana painted a stark picture of the current market. No customer is getting 100% of what they want from Micron. Many are receiving substantially less than what they need.

The company is prioritizing AI-related demand. This strategy helps non-AI product margins too. When you’re turning away customers, you can be selective about who gets served first.

Micron beat expectations for its fiscal first quarter as well. Sales hit $13.64 billion versus estimates of $12.85 billion. Adjusted profit came in at $4.78 per share, topping the $3.95 consensus.

Revenue surged 57% year-over-year. Net income reached $5.24 billion, or $4.60 per share. That compares to $1.87 billion in the same period last year.

Betting Big on AI Infrastructure

The company is putting its money where its mouth is. Micron raised its 2026 capital expenditure plans to $20 billion. The previous estimate was $18 billion.

That cash will go toward adjusting production facilities for AI data center demand. Earlier this month, Micron announced it WOULD dissolve its consumer-facing “Crucial” brand. The company is exiting direct-to-consumer memory chip sales entirely.

Cloud memory sales doubled on an annual basis to $5.28 billion. Core data center sales reached $2.38 billion, up 4% year-over-year. Both segments benefited from higher pricing.

Server unit demand has strengthened significantly. Mehrotra said server units grew in the high teens during 2025. This growth drives demand for high-performance, high-capacity memory and storage.

The company is negotiating multiyear contracts with key customers. These agreements provide visibility and help manage capacity allocation.

For the current quarter, Micron expects revenue of $18.70 billion, plus or minus $400 million. Wall Street had been modeling $14.20 billion.
