AI Memory Boom Reshapes Chip Profits as Apple’s Record Quarter Runs Into Supply Strains

HBM’s surge is constricting supply chains, pressuring device margins.

Overview

  • Apple posted fiscal Q1 revenue of $143.8 billion, up 16%, with iPhone sales hitting a record $85.27 billion and the active device base topping 2.5 billion.
  • Management said AI-driven demand is squeezing memory availability and advanced packaging, leaving inventories tight; NAND is secured for Q1, DRAM commitments cover only the first half, and gross margin pressure is expected to build.
  • Samsung reported record Q4 results with 93.8 trillion won in revenue and 20.1 trillion won in operating profit, reclaimed the DRAM sales lead, and said HBM4 is complete with shipments to NVIDIA starting next month.
  • SK Hynix also delivered record quarterly revenue and profit on strong HBM demand, with analysts noting SK’s technology lead as Samsung accelerates to catch up.
  • Counterpoint said Q4 2025 smartphone revenue rose 13% to $143 billion as average selling prices topped $400 for the first time, with higher component costs and premium mix likely to curb 2026 unit growth and push vendors toward higher-value models.
