**Micron's fiscal Q1 2027 DRAM revenue outlook is shaped by sustained AI-driven demand for high-bandwidth memory (HBM) and conventional DRAM amid tight industry supply.** Following record fiscal 2026 results—with full-year DRAM revenue surpassing $100 billion and Q4 DRAM at $39.8 billion (73% of $54.2 billion total revenue)—the company guided fiscal Q1 total revenue to $61.5 billion ±$1.5 billion. This implies DRAM likely in the mid-$40 billion range assuming a similar mix, supported by pricing strength, high-teens sequential ASP gains in recent quarters, and long-term supply agreements locking in substantial commitments. Key catalysts include continued data center growth, HBM ramp, and expectations for tighter supply-demand balance through 2028, with sequential quarterly revenue increases projected for fiscal 2027. Traders are monitoring bit shipment trends, competitive output from Samsung and SK Hynix, and any shifts in ASPs or inventory dynamics ahead of the next earnings release.
