Overview
- Micron has been a major beneficiary of AI infrastructure spending and its shares have surged roughly 1,300% over the past five years as demand for memory rose.
- The market now prices a wide gap between past and expected profits, with Micron trading at about 22.9 times trailing earnings but near 6.6 times forward estimates, reflecting concerns that this cycle could be peaking.
- Supply risk is growing because Micron is building six new fabs, including a large Idaho site that will ramp DRAM production in 2028, while South Korean rivals plan fabs coming online in 2028–2029.
- Customer-level shifts could trim demand intensity: reports say Nvidia scaled back Rubin systems to 4‑hi high‑bandwidth memory (HBM) from larger 8‑hi/12‑hi stacks, and lower stack heights cut the amount of memory used per AI server.
- What matters next is how Micron’s upcoming quarterly report addresses sustainment of AI pricing and demand because rising capacity and reduced per‑system memory could push prices down, affect Micron’s capital plans and change hiring and supplier decisions.
