Micron to buy Powerchip’s P5 fab site in Taiwan for $1.8B cash, expanding DRAM wafer capacity with production planned from H2 2027

Micron ($MU) signed a letter of intent to buy Powerchip’s P5 fab site in Taiwan for $1.8B cash, adding roughly 300,000 square feet of cleanroom space to expand DRAM wafer output starting in H2 2027 as memory demand (especially AI-linked HBM) continues to outpace supply.

Why this matters to markets

1. Capacity and supply chain control: Owning more DRAM capacity can help Micron manage mix, yields, and ramp timing versus relying solely on existing footprint.

2. AI memory remains the bottleneck: HBM is essential for AI accelerators, and Micron is one of only 3 major HBM suppliers, so any credible capacity path can shift sentiment across the AI stack.

3. Longer-dated impact, nea ...
