Micron Q4 Earnings Show 900%+ Profit Growth on HBM Demand Surge

Micron’s results reflect a structural shift in DRAM and NAND pricing power. Average selling prices for high-bandwidth memory (HBM) rose above $20 per unit in the quarter while legacy DRAM ASPs stabilized after 18 months of contraction. This margin expansion occurred with minimal incremental capex, producing operating margins above 25 percent versus 3 percent a year earlier.

The earnings release aligns with documented supply discipline across the top three DRAM producers. Samsung and SK Hynix have maintained 2024 bit-growth guidance below 15 percent despite recovering end demand, a pattern visible in their October 2024 investor briefings. Secondary effects appear in upstream equipment orders: ASML EUV bookings for advanced nodes increased 12 percent sequentially in Q3, consistent with memory makers allocating capacity to HBM3E and HBM4.

Valuation ripple effects extend beyond chipmakers. S&P 500 semiconductor equipment names trade at forward multiples 8 points above their five-year median, while contract manufacturers with high memory content face margin compression risk if ASP gains prove transitory. Data-center capex plans filed by hyperscalers for 2025 show memory budgets rising 35-40 percent, locking in volume commitments through 2026.

Next data points include Micron’s December 2024 capex guidance and Samsung’s Q4 earnings due in late January; divergence between the two would signal whether the current upcycle has synchronized across the oligopoly.
