Sony slides 3% as Bernstein slashes target 27% on memory cost fears
AI-driven DRAM and NAND price surge expected to pressure PlayStation 5 margins and semiconductor earnings
Sony Group Corp shares tumbled 3% on Tuesday after Bernstein downgraded the electronics and entertainment conglomerate, citing an imminent surge in memory prices that threatens to erode profitability across its gaming and semiconductor businesses.
The Wall Street firm cut its rating on Sony to "Market Perform" from "Outperform" and reduced its price target by 27% to $22 from $30, according to a research note. The downgrade triggered a sell-off that pushed NYSE-listed shares down to $20.99, marking the stock's steepest single-day decline in nearly three months.
The catalyst for Bernstein's bearish shift is a dramatic escalation in DRAM and NAND flash prices, driven by insatiable demand from artificial intelligence infrastructure providers. Analysts project memory prices could rise more than sevenfold by year-end as manufacturers prioritize production of high-bandwidth memory for AI accelerators, creating severe supply constraints for conventional consumer electronics.
"Soaring DRAM and NAND prices, driven by intense AI-related demand, are creating a major cost challenge for consumer-electronics makers," Bernstein analysts wrote in their report. The firm estimated that PlayStation 5 hardware contained approximately $100 in memory costs per unit during 2025, with high double-digit percentage increases expected this year.
The memory cost surge comes at a particularly vulnerable moment for Sony's gaming division. In February, the company reduced its full-year PlayStation 5 sales forecast by 4 million units to 21 million, citing weaker-than-expected holiday performance. Bernstein now expects Sony to further reduce PS5 shipment volumes to manage hardware losses, noting that the company has "fewer cost-cutting options" after scaling back live-service game development investments.
The structural nature of the memory supply crunch compounds Sony's challenges. DRAM prices have nearly tripled since early 2026, with contract prices rising 90-95% quarter-over-quarter in Q1. PC DRAM could jump 105-110% this quarter, effectively doubling, while NAND flash prices are projected to increase 55-60%, with some forecasts calling for an 85-90% surge. All 2026 high-bandwidth memory capacity is already sold out, and manufacturers are allocating production capacity away from consumer markets to serve AI data center customers.
Sony's semiconductor segment, which generates substantial revenue from smartphone image sensors, faces additional headwinds. Bernstein warned that elevated memory prices combined with declining global smartphone shipments could lead to slower growth and market share losses to competitors including Samsung Electronics. The brokerage noted that smartphone makers are already raising device prices to absorb memory cost increases, which could dampen consumer demand for new handsets equipped with Sony's camera sensors.
The downgrade represents a sharp reversal from Bernstein's previous bullish stance, despite Sony reporting record operating income of ¥515 billion ($3.4 billion) in its fiscal third quarter. The company's strong earnings performance, driven by robust demand for PlayStation software and network services, had previously overshadowed concerns about component costs. However, the scale and persistence of the memory price surge—expected to continue through 2027 and potentially into 2028—has shifted the risk-reward calculation.
Sony's chief financial officer acknowledged memory cost pressures during the February earnings call, saying the company was working with suppliers to secure adequate supply and planned to mitigate the impact by focusing on monetizing the PlayStation installed base through software and services revenue. However, Bernstein's note suggests these measures may be insufficient to offset a cost environment characterized by unprecedented price increases across all memory categories.
The downgrade highlights a growing divide in the semiconductor sector between AI beneficiaries and traditional consumer electronics companies. While chipmakers like SK Hynix, Samsung, and Micron are prioritizing AI-related production and capturing premium pricing, companies like Sony that depend on conventional memory for mass-market products face margin compression and potential demand destruction as retail prices rise.
Sony's stock had been trading near its 52-week high of $30.34 earlier this month before Tuesday's decline, reflecting investor optimism about the company's entertainment and financial services businesses. The Bernstein downgrade now places Sony's shares below both its 50-day moving average of $22.93 and 200-day moving average of $26.18, signaling potential technical weakness as the stock adjusts to a more cautious growth outlook.
