NEW YORK — Micron Technology shares surged more than 6% on Monday after the Boise-based memory chipmaker announced the completion of its $1.8 billion acquisition of Powerchip Semiconductor Manufacturing Corporation's P5 facility in Tongluo, Taiwan, and unveiled plans for a second manufacturing facility at the same site. The stock's jump extended a 7.3% gain from Friday, making Micron one of the strongest performers in the semiconductor sector this week ahead of its closely watched quarterly earnings report on Wednesday.
The P5 site in Miaoli County adds approximately 300,000 square feet of existing 300mm cleanroom space to Micron's production footprint, located roughly 15 miles from the company's existing mega campus in Taichung. Retrofitting work has already begun, with the facility being equipped for extreme ultraviolet lithography to manufacture leading-edge DRAM products including HBM3E and the upcoming HBM4 chips. Micron said meaningful product shipments from the new site are expected by fiscal 2028, with construction on a second comparable facility at the same Tongluo location scheduled to begin by the end of fiscal 2026.
"This is a generational inflection point in memory pricing," wrote analysts at Wedbush Securities, which raised its price target for Micron to $500 following the announcement. The firm cited a supply-demand imbalance in high-bandwidth memory that it expects to persist well into 2027. Micron's 2026 HBM capacity is fully sold out, and the company has been unable to fully satisfy demand from hyperscale data center customers who are scaling AI training and inference infrastructure at record pace.
The acquisition and expansion announcement arrives at a strategically sensitive moment: Micron is set to report fiscal second-quarter 2026 results on Wednesday, with Wall Street consensus pointing to approximately $18.7 billion in revenue and $8.42 in non-GAAP earnings per share. Prediction market data suggests a nearly 98% probability of Micron beating the revenue consensus, reflecting the extraordinary demand environment for AI memory products. Micron's Q1 revenue of $13.6 billion represented a 57% increase from the year-earlier period.
The strategic logic of the Taiwan expansion is difficult to challenge. High-bandwidth memory has emerged as one of the most critical bottlenecks in AI system performance, with HBM chips stacked alongside graphics processing units in AI accelerators to provide the massive memory bandwidth needed for large language model inference. Nvidia's Blackwell and Vera Rubin chip families — highlighted extensively at the GTC conference on Monday — require significant HBM content per chip, and both Samsung and SK Hynix, Micron's primary competitors in the HBM market, are also operating at or near full capacity.
From a valuation standpoint, Micron's forward price-to-earnings ratio of roughly 13 times next year's estimates appears undemanding relative to its growth profile, which has attracted institutional accumulation from prominent funds. Year-to-date, Micron shares have gained approximately 49%, vastly outpacing the S&P 500's slight decline over the same period. Mizuho, Wolfe Research, and Deutsche Bank have all raised their price targets in recent weeks, with a consensus bull case pointing to continued upside through the current AI infrastructure cycle.
Analysts also highlighted the geopolitical dimension of the Taiwan expansion, noting that Micron's deepening manufacturing presence on the island — at a time when the semiconductor industry is under pressure to diversify production — could attract regulatory scrutiny but also positions the company to benefit from the next phase of government incentive programs supporting allied-nation chip manufacturing investment.
