Tim Cook's Last Warning as Apple CEO Was That Memory Chip Shortages Won't Improve Any Time Soon. Here's What That Means for Apple's Margins Under John Ternus.

Apple expects margins to fall to 46.5% in the September quarter (from 48.1% in June, excluding tariff benefits), citing ongoing DRAM memory cost inflation tied to a supply shortage. Management warned rising memory prices could further weigh on profitability and potentially iPhone sales, even as Apple tests alternate suppliers (e.g., CXMT for China) and raises some device prices. The outlook suggests a temporary margin headwind for the early period under new CEO John Ternus.

Analysis

The important mechanism is not a one-quarter gross margin wobble; it is a transfer of bargaining power from consumer-device OEMs to memory vendors as AI/datacenter demand crowds out commodity DRAM supply. That favors the concentrated memory oligopoly and hurts hardware makers with weaker pricing power, especially those whose upgrade cycles depend on keeping entry prices stable. Apple can offset some of the pain with higher ASPs, but if it leans too hard, the risk shifts from margin compression to unit elasticity and mix down-trading over the next 1-3 quarters.

For MU and SK Hynix, this is a duration story more than a headline trade: if supply stays tight into 2026, memory pricing can support multiple expansion, not just better revenue. The second-order effect is that smartphone and PC OEMs may defer features or raise prices broadly, which tends to slow replacement cycles and push more demand toward premium tiers. That makes the demand shock asymmetric: suppliers capture scarcity rents now, while handset makers absorb the loss in volume or mix.

The contrarian point is that the market may be underestimating Apple's pricing power and overestimating the permanence of the squeeze. If AI capex cools or a new supply wave lands, DRAM can turn quickly and memory suppliers' margins can mean-revert faster than the street expects. The key falsifier is a slowdown in DRAM ASPs or signs that Apple’s price hikes are denting sell-through after the launch window.

Key Decisions for Investors

• Long MU / short AAPL pair trade over the next 1-3 months: target relative outperformance if DRAM pricing stays firm and Apple’s price hikes start to pressure units; cut if AAPL sell-through data remains resilient or MU guides to easing DRAM ASPs.
• Use any post-launch strength in AAPL to buy 1-3 month downside put spreads rather than outright shorting; the thesis only works if higher BOM costs start to show up in volume/mix, not just gross margin.
• Add to MU on pullbacks only if channel checks confirm tight DRAM inventories and long lead times; stop out if inventory days rise or management commentary turns to normalization.
• Watch for a read-through to handset and PC OEMs as a sector pair short against memory suppliers; if feature prices rise broadly, consumer-electronics margins should lag semis for the next 2 quarters.
