Woofun AI reports that Goldman Sachs maintained a "mildly positive" outlook in its June 30th DRAM Sentiment Index while significantly revising its forecast for Samsung Electronics' 2027 High Bandwidth Memory (HBM) price increase from 14% to 44%. This adjustment reflects a complex interplay between HBM supply constraints, surging traditional DRAM valuations, and downstream requirements from NVIDIA, AMD, and other AI accelerator card manufacturers. The shift directly influences the projected profit margins for major memory producers including Samsung, SK Hynix, and Micron as they navigate an evolving market landscape.

Market dynamics have shifted sharply since early May, with DDR5 spot prices climbing 20% and trading at a 25% premium over May contract levels. Simultaneously, DDR4 spot prices rose 11% during the same period, establishing a substantial 45% premium against May contracts. As these mainstream DRAM price increases become more pronounced, the reference pricing for HBM in next year's supply agreements has been correspondingly elevated. This pricing power stems from the fact that memory manufacturers now hold a stronger position when negotiating with cloud providers and AI chip companies, leveraging the broader strength of the traditional memory sector.

Structurally, HBM presents unique challenges compared to standard DRAM, including higher capacity conversion complexity, extended customer certification cycles, and significantly reduced supply elasticity. These factors limit the ability of manufacturers to rapidly scale production in response to demand spikes, thereby reinforcing the pricing leverage observed in recent months. The June DRAM Sentiment Index remained "mildly positive", consistent with the April reading, supported by upward trends in spot prices, server-related revenue, South Korean exports, and Taiwanese manufacturer earnings.

However, a drag factor exists in the second-order change of Samsung's DRAM average selling price growth rate, suggesting that while prices remain on an upward trajectory, the momentum of price hikes may decelerate following the second quarter.

Official data from South Korea underscores the robustness of the DRAM export sector. South Korean MOTIE data indicates that total exports reached $87.8 billion in May 2026, representing a year-on-year surge of 53.2%. Within this total, DRAM exports accounted for $18.6 billion, a staggering year-on-year increase of 369.8%, while NAND exports grew by 206.8% year-on-year. South Korea's May DRAM export revenue expanded by 21% compared to the previous month, significantly surpassing the highs recorded in March. These figures validate the strength of the export market and support the bullish sentiment held by major financial institutions.

Data compiled by Woofun AI shows that Taiwanese manufacturers are also reflecting strong price elasticity, particularly in the DDR4 segment. Nanya Technology reported consolidated revenue of NT$27.67 billion in May 2026, marking an 8.55% month-on-month increase and a massive 730.14% year-on-year jump. Distributor WPG Holdings experienced similar growth, with revenue surging 253% year-on-year and 54% month-on-month in May.

Furthermore, Taiwanese server ODM manufacturers saw monthly revenue rise by 53% year-on-year in May, driven primarily by increased shipments of rack-level AI servers and ASIC AI servers. Inventec specifically recorded a 69% year-on-year revenue increase during the same period, highlighting the direct correlation between server demand and component pricing.

Goldman Sachs projects that Samsung's DRAM average selling price will rise approximately 46% quarter-over-quarter in 2Q26E, followed by a moderation to 15% in 3Q26E and 7% in 4Q26E. Despite the strong performance in the memory sector, the consumer electronics market faces headwinds. Chinese smartphone shipments grew 19% year-on-year and 7% month-on-month in May, yet cumulative shipment volume from 2026 to date remains essentially flat compared to 2025. Analysts predict a 14% year-on-year decline in 2Q26 shipments, largely attributed to rising memory prices potentially dampening terminal demand.

In terms of investment strategy, Goldman Sachs maintains a "Buy" rating for both Samsung's common and preferred stock. The firm set a 12-month target price of 480,000 Korean won for common stock and 360,000 Korean won for preferred stock. Downside risks identified include a significant deterioration in memory supply and demand dynamics, a sharp contraction in smartphone profit margins, and a potential loss of market share in mobile OLEDs. This marks a critical juncture where memory pricing power could either sustain high margins or trigger a demand correction in the broader consumer electronics ecosystem.
