Micron to Buy PSMC Taiwan Fab for $1.8B as Q3 Revenue Soars 57%

MUMU

Micron’s Q3 FY2025 revenue jumped 57% YoY to $13.6B on AI-driven DRAM and HBM growth, with net income margins climbing nearly eightfold since Q1 2024. The company will acquire PSMC’s Taiwan P5 fab for $1.8B to expand capacity—extra DRAM output arrives by H2 2027—and trades at ~11x forward P/E.

1. Structural Shift to AI-Driven Memory Demand

Micron Technology has effectively transitioned from traditional consumer-driven memory cycles to enduring, AI-centric demand, positioning itself as a key beneficiary of the generative AI boom. In Q3 2025, the company reported revenue of $13.6 billion, up 57% year-over-year, driven largely by cloud data-center build-outs and HBM deployment. Since Q1 2024, net income margins have expanded nearly eightfold, a testament to sustained pricing power and mix improvement as Micron reallocates capacity toward high-margin HBM products and exits commodity PC DRAM.

2. Rapid HBM Market Share Gains and Technical Leadership

Micron’s investment in high-bandwidth memory (HBM3 and HBM4E) has yielded a rise to roughly 26% of global HBM/DRAM market share in Q3 2025, up from the mid-teens a year earlier. Technical advancements—such as a customized HBM4E module offering 2.5× greater bandwidth—have underpinned share gains against peers. The company’s IDM model, with in-house wafer fabs and advanced stacking capabilities, contrasts with fabless competitors and reinforces its control over the end-to-end AI memory supply chain.

3. Strategic Expansion via Taiwan Fab Acquisition

In a landmark deal, Micron signed a $1.8 billion letter of intent to acquire Powerchip’s P5 fabrication facility in Taiwan, securing additional DRAM output to meet anticipated AI infrastructure needs. Although integration and yield ramp are expected to complete by H2 2027, this acquisition bolsters Micron’s capacity roadmap amid industry-wide supply constraints and underpins long-term pricing leverage.

4. Valuation and Future Margin Upside

Analyst consensus maintains a Strong Buy rating, citing a forward P/E near 11×—below the semiconductor industry average—and projected EPS of $33 in fiscal 2026 and $41.50 in fiscal 2027. With gross margins having climbed from 38.5% to over 56% in the past year and further upside possible as HBM volume grows, Micron’s valuation reflects both its deepening AI footprint and the potential for continued margin expansion through the next AI supercycle.
