Management is asking customers to bring competitors' wafers because their own 8Gb DRAM platform is missing.
Thesis: PSMC is attempting a triple execution leap that their aging infrastructure cannot support. They are relocating a fab, skipping nodes from DDR3 to DDR4, and building an HBM backend for Micron simultaneously. They have zero pricing power. Micron owns the IP and the customer. The 20% 3DAI revenue target is a fantasy until they prove they can handle the yield on a node skip they have missed for years.
Verdict: SHORT — Conviction: MEDIUM
Catalyst: Failure to qualify 8Gb DDR4 or a miss on the PMIC volume ramp to 40,000 wafers.
Key Risk: The DRAM cycle extension keeps legacy pricing high enough to mask execution failure in the AI segment.
The Tell: Management admitted they told customers to bring wafers from competitors for stacking because their own 8Gb platform did not exist yet. This is an admission of technical obsolescence.
Friction Level: HIGH_FRICTION — The Micron deal is either a strategic entry into HBM or a capital-heavy toll-processing arrangement that strips PSMC of pricing power.
