What is the impact of rising memory prices on smartphone sector?

Bernstein warns that a sharp rally in DRAM and NAND prices—fueled by hyperscalers’ AI demand—will unevenly squeeze smartphone economics, forecasting mobile DRAM contract prices up 30–40% QoQ in Q4 with further increases and supply constraints likely into H1 2026. The impact is tiered: memory is ~4% of iPhone ASP, ~7% of a Xiaomi flagship and >10% of a Redmi mid-range device, so a 40% memory increase could shave 2–3 percentage points off Xiaomi’s smartphone gross margin; Xiaomi’s shift to higher-end models (Xiaomi 17 shipments +30%, 80% Pro mix) provides some insulation but passing costs risks volumes. Component suppliers face mixed outcomes—camera lens makers are relatively protected while module vendors and low-end camera budgets are vulnerable—and Bernstein argues concern over Sunny Optical is overstated, still forecasting modest 2026 revenue and EPS growth even in a downside scenario. Overall, OEMs are reworking product mixes, the Android supply chain is cautious, and consumers—especially at the low end—may see higher handset prices next year.

Analysis

Bernstein highlights a sharp rally in mobile DRAM and rising NAND prices driven by “strong demand from hyperscalers for AI,” forecasting mobile DRAM contract prices to rise 30–40% quarter-on-quarter in Q4 with further increases and supply constraints likely into H1 2026. Suppliers are reportedly “very adamant on price increases,” implying sustained upstream pricing pressure through 2026.

The price shock will be uneven across device tiers: memory is roughly 4% of an iPhone ASP, ~7% of a Xiaomi flagship and >10% of a Redmi mid‑range phone, so Bernstein estimates a 40% memory rise could shave 2–3 percentage points off Xiaomi’s smartphone gross margin. Xiaomi’s shift toward higher‑end models (Xiaomi 17 shipments +30% with an 80% Pro mix) provides partial insulation, but passing costs to consumers risks volume declines and the margin impact typically lags memory moves by about one quarter.

Component outcomes are mixed: camera lens makers are relatively insulated by consolidation and technical barriers, while modules and low‑end camera budgets face delayed margin pressure and potential downgrade of features next year. Bernstein revisits Sunny Optical and, even in a bear case of no smartphone revenue growth and margin deterioration in low‑to‑mid products, still models modest 2026 revenue and EPS growth, leading analysts to suggest accumulation before the next earnings release amid cautious Android supply‑chain sentiment.

Key Decisions for Investors

• Investors should underweight exposure to low‑to‑mid‑range Android OEMs whose margins are most exposed to DRAM/NAND inflation and where memory is >10% of ASP,
• Prefer suppliers and OEM exposure tied to high‑end devices or Apple’s supply chain where memory is a smaller ASP component and disruption is limited,
• Consider a measured accumulation of Sunny Optical ahead of the next earnings release as Bernstein views current concerns as overstated, sizing positions conservatively given near‑term Android weakness,
• Monitor Q4–H1 2026 DRAM/NAND contract price trajectories, hyperscaler AI demand trends, and Xiaomi volume/mix data (Xiaomi 17 shipments and Pro mix) as key triggers to reassess positioning and potential pass‑through to consumer pricing
