Micron Surges 5% as Taiwan Factory Deal and HBM4 Sell-Out Fuel Pre-Earnings Rally
Micron Technology (MU) shares jumped 5.38% to $449.05 on Monday, significantly outperforming a cautious S&P 500 as the company finalized a major manufacturing expansion in Taiwan and confirmed its high-bandwidth memory (HBM4) capacity is fully sold out through 2026. The rally comes just 48 hours before Micron is scheduled to report fiscal second-quarter earnings, with investors aggressively positioning for a projected 450% surge in year-over-year bottom-line growth.
Taiwan Expansion and HBM4 Dominance
Micron shares caught a massive bid during Monday's session following the official completion of its $1.8 billion acquisition of Powerchip Semiconductor Manufacturing Corp’s (PSMC) P5 facility in Taiwan. The deal immediately adds 300,000 square feet of clean-room capacity, which Micron intends to use for the rapid scale-up of DRAM and High Bandwidth Memory (HBM).
In a move that surprised the market, Micron also announced plans to break ground on a second, similarly sized facility at the same Tongluo site before the end of fiscal 2026. This aggressive physical expansion underscores the company's struggle to keep pace with AI-driven demand. Management confirmed that its entire HBM4 supply for calendar year 2026 is already committed under binding long-term agreements, providing the company with unprecedented revenue visibility through the next eight quarters.
Earnings Countdown: The $500 Price Target
Today's 5.38% move is being amplified by a wave of bullish analyst revisions ahead of the March 18 earnings call. Wedbush Securities recently raised its price target on MU to $500 from $320, citing memory pricing that has moved "well ahead of expectations." Analysts now expect Micron to report Q2 earnings of approximately $8.60 per share—a staggering increase from the $1.79 reported in the same period last year.
Citigroup and Susquehanna also lifted their targets this week, noting that DRAM average selling prices could rise as much as 171% in 2026. The market is currently pricing in a 97% probability of an earnings beat, as the supply-demand mismatch in the semiconductor sector remains acute. While competitors like SK Hynix and Samsung are also racing to expand, Micron’s status as the primary U.S.-based manufacturer is earning it a "geopolitical premium" among domestic hyperscalers.
Sector Context and Macro Decoupling
Micron’s performance is particularly notable given the broader market's relatively muted 0.80% gain. While geopolitical tensions in the Middle East have introduced volatility into the energy and transport sectors, the semiconductor industry is decoupling as hardware-led AI innovation becomes the dominant market theme for 2026.
Technically, MU is trading near all-time highs, with today's volume of 23.7M shares suggesting strong institutional accumulation. Investors are increasingly viewing Micron not as a cyclical commodity play, but as a structural AI infrastructure staple with margins that more closely resemble software platforms. Looking ahead to Wednesday, the focus will shift from the inevitable "beat" to management’s guidance on how soon the new Taiwan capacity can begin contributing to the bottom line, with current estimates pointing toward a production ramp in early 2027.
Key Takeaways
- Micron finalized a $1.8 billion acquisition of a Taiwan manufacturing site to immediately boost HBM and DRAM capacity.
- The company confirmed its HBM4 supply is fully sold out through calendar 2026, ensuring high pricing power for the next two years.
- Analysts at Wedbush and Citigroup have raised price targets toward $500 ahead of Wednesday's high-stakes Q2 earnings report.
- Projected Q2 EPS of $8.60 represents a more than 450% year-over-year increase, driven by insatiable AI data center demand.
