Micron’s AI-Driven Surge: Record Highs and Supply Constraints Fuel Optimism

Shares of memory chip manufacturer Micron Technology soared to a new peak recently, propelled by a potent combination of robust quarterly results and a significantly upgraded price target from Wall Street. The central narrative driving investor enthusiasm revolves around the artificial intelligence boom and a critical question: how long can the company benefit from tight supply and rising prices?

The bullish sentiment is grounded in exceptional financial results Micron reported in mid-December for its first quarter of fiscal 2026. The company delivered record figures across its profit and loss statement:

• Revenue: $13.64 billion, representing a 56% year-over-year increase and 21% sequential growth.
• GAAP Earnings Per Share (EPS): $4.60, a substantial jump from $1.67 in the prior-year period.
• Adjusted EPS: $4.78, surpassing market expectations.
• Gross Margin: Reached 56.0%, a dramatic expansion from 38.4% the previous year—a gain of 17.6 percentage points.
• Free Cash Flow: $3.9 billion, a record high compared to just $112 million in the year-ago quarter.

CEO Sanjay Mehrotra highlighted "record revenue and significant margin expansion" across all business units, noting new highs for revenue, gross margin, EPS, and free cash flow. The powerful effect of higher pricing and improved capacity utilization was clearly evident.

Analyst Upgrade Ignites Rally

The immediate catalyst for the stock's latest jump was a research note from Sanford C. Bernstein. On Friday, analyst Mark Li raised his price target for Micron from $270 to $330, reaffirming his "Outperform" rating. This endorsement sent the stock climbing by double digits, closing at a fresh 52-week high of $315.42.

Li's optimism is based on two primary drivers:

1. A significant acceleration in DRAM pricing.
2. Sustained, powerful demand from AI data centers.

He forecasts a sequential increase in DRAM prices of 20% to 25% for the second fiscal quarter, with this pricing momentum expected to persist throughout calendar year 2026. The analyst points to a structural supply-demand imbalance, where demand for AI data center infrastructure is outpacing the industry's ability to ramp up production capacity.

Forward Guidance Points to Further Margin Expansion

Perhaps more critical for the current investment thesis is Micron's own forward-looking guidance. For its second fiscal quarter of 2026, the company provided the following outlook:

Should investors sell immediately? Or is it worth buying Micron?

• Revenue: $18.70 billion, plus or minus $400 million (approximately 37% sequential growth).
• Gross Margin: 67.0% ± 1.0% (GAAP) and 68.0% ± 1.0% (non-GAAP).
• EPS: $8.19 ± $0.20 (GAAP) and $8.42 ± $0.20 (non-GAAP).

This projection implies an additional 11-percentage-point climb in gross margin from the already strong previous quarter, signaling continued pricing power and extremely high utilization rates. Concurrently, Micron has increased its capital expenditure plan for fiscal 2026 from $18 billion to $20 billion, a clear signal from management that it views the strong demand as a long-term trend rather than a short-term spike.

High-Bandwidth Memory: Capacity Fully Booked

A cornerstone of Micron's growth story is its position in High-Bandwidth Memory (HBM), a critical component for AI accelerators. The company states that its entire HBM production capacity for calendar year 2026 is already fully allocated under supply agreements, including for the upcoming HBM4 generation.

Micron anticipates the total addressable market for HBM will grow to approximately $100 billion by 2028. Starting from around $35 billion in 2025, this represents a compound annual growth rate of roughly 40%. The company does not expect supply constraints to ease quickly, predicting that tight market conditions will persist "beyond calendar year 2026." In response, Micron is increasingly focusing on multi-year contracts with clearly defined volume and pricing terms.

Sector-Wide Momentum

The positive sentiment surrounding Micron spilled over into the broader semiconductor sector on Friday. Shares of other memory and storage companies like Seagate Technology and Western Digital also posted significant gains, lifted by expectations that AI data center expansion and global chip shortages will improve industry profitability. Major CPU and GPU providers such as Intel and AMD benefited as well, with the Philadelphia Semiconductor Index outperforming the broader market.

Micron's own equity has been on a remarkable run, gaining over 50% in the past 30 days. The stock currently trades at its 52-week high, more than 400% above its low point from April 2025.

Spring Milestones Loom

The next key test for the company is already scheduled. In late March 2026, Micron will report results for its second fiscal quarter and provide guidance for the third quarter. Three areas will be of particular importance to investors:

• Confirmation of the anticipated 20–25% sequential DRAM price increases.
• Details on the ramp-up of HBM4 production and the qualification of new customers.
• Progress updates on U.S. manufacturing plans, including the accelerated timeline for its Idaho facility (now targeted for mid-2027).

Whether Micron can justify the current market optimism will become clearer this spring. However, following the substantial rally and ambitious forecasts, the bar for performance is now set considerably higher than it was just a few months ago.
