With its recent stock performance and earnings announcement causing anxiety for many investors, let's explore together whether this is a moment of crisis or a new opportunity. Why Q2 2025 Earnings Fell Short of Expectations According to the DS Investment & Securities report, Samsung SDI's Q2 2025 performance unfortunately fell short of market expectations (consensus). While revenue was about 3.2 trillion KRW, the operating loss reached 397.9 billion KRW. So, why did this happen? The biggest reason was the slump in the large-to-medium-sized battery division . This was due to delays in electric vehicle (EV) supply to major clients and the increased burden of fixed costs from its joint venture (JV) with Stellantis. Furthermore, tari...

SK Hynix : DS Investment & Securities report KOREA Memory Semiconductor Market in 2025

SK Hynix: Opening a New Chapter in the Memory Semiconductor Market in 2025

SK Hynix: Opening a New Chapter in the Memory Semiconductor Market in 2025

SK Hynix's (000660) impressive Q2 2025 performance and future outlook, based on the latest report from DS Investment & Securities. Let's explore how SK Hynix, along with HBM (High Bandwidth Memory), a hot topic in the semiconductor market, will lead the market.

Clear Strong Performance, Exceeding Expectations!

SK Hynix recorded its highest quarterly performance in Q2 2025 with revenue of KRW 22.2 trillion (+26% QoQ) and operating profit of KRW 9.2 trillion (+24% QoQ). Notably, its operating profit margin (OPM) reached 41%, demonstrating overwhelming profitability.

  • DRAM's Driving Force: In Q2, the DRAM segment led the overall performance, recording a Bit Growth (B/G) of +25% and an Average Selling Price (ASP) of +3%.
  • NAND's Reversal: The NAND segment recorded a B/G of +71%, significantly exceeding the forecast (+20%). Although ASP decreased by -9%, the increase in shipments due to rising unit prices, increased demand for eSSD (enterprise Solid State Drive) from hyperscalers (companies operating large-scale data centers), and increased mobile set sales in Greater China were key factors. It's very positive that the company reached normal inventory levels in Q2 thanks to increased shipments.

2026 HBM, A Future Already Secured!

At this earnings announcement, SK Hynix sent a clear message regarding the most significant concerns: the progress of HBM supply contracts for 2026 and worries about intensified competition. The upward adjustment of Capex (capital expenditure) for 2025 (mid-KRW 20 trillion range) is interpreted as a strong signal that visibility and profitability for 2026 HBM volumes have already been secured.

Of course, a price decline for older products after a new product launch is a common phenomenon. However, this issue is not exclusive to SK Hynix. Given SK Hynix's cost competitiveness, which currently yields HBM margins of 60-70%, the margin gap with competitors could widen further. This suggests that its leadership in the HBM market will be further solidified.

The Unextinguished Flame of the Memory Upcycle

With recent requests for long-term DDR4 supply contracts, memory manufacturers are expected to maintain a conservative supply stance. This anticipates an acceleration in DDR5 adoption and tight supply-demand conditions in 2026.

Some in the market believe that the rise in DRAM prices is due to temporary pull-in demand (demand brought forward) and that its sustainability will be low in the second half. However, the report analyzes that memory suppliers' DRAM inventories in the second half are tight, and component inventories are also healthy despite increased B/G. This is strong evidence that the memory upcycle (a period of upward growth in the industry's cycle) will continue, leading to expectations of SK Hynix's record-breaking performance in 2026.

The Infinite Potential of HBM in the Age of Artificial Intelligence (AI)

The growth of the AI market is a key driver for increased HBM demand. The continuous expansion of CAPEX by big tech companies, rapidly increasing token usage, and the growth of AI startups confirm the explosive growth of the AI market. As AI workloads expand from training to inference, and further subdivide into Reasoning, Agent (AI that autonomously achieves goals), etc., bandwidth bottlenecks are intensifying, meaning HBM's role is becoming even more crucial.

Furthermore, there is a movement to offload (transferring workload to another device to reduce burden) AI inference data caching (a technique to temporarily store frequently used data for faster access) to eSSD, with initial demand expected to become visible in 2-3 years. This will also positively impact SK Hynix's NAND business.

Investment Areas and Strategic Suggestions

Based on the SK Hynix report, we suggest investment areas and strategies for investors to consider, linked to current market conditions.

  • Semiconductor Stock Investment (Focus on SK Hynix):
    • Strategy: SK Hynix is a leader in the HBM market and a key beneficiary of the AI era. From a long-term perspective, consider staggered purchases and focus on the company's fundamental growth rather than short-term market volatility.
    • Potential Risks: Global economic recession, recurrence of semiconductor oversupply, intensifying US-China tech rivalry, and competitors catching up in HBM technology.
  • Memory Semiconductor ETF (Exchange Traded Fund) Investment:
    • Strategy: If individual stock investment is a burden, consider investing in ETFs that hold domestic and international memory semiconductor-related companies to diversify. This approach reduces the risk of specific companies while investing in the overall industry growth.
    • Potential Risks: ETFs may not offer the high returns of individual stocks and are concentrated in a specific sector, posing a risk of loss if that sector declines.
  • AI-related Tech Stock Investment:
    • Strategy: Focus on the growth of the AI market driving HBM demand and seek investment opportunities across the entire AI ecosystem, including AI semiconductor design companies and AI software development companies.
    • Potential Risks: The rapid changes in AI technology and intensifying competition can lead to uncertainty in the growth potential of specific companies, and regulatory risks also exist.
  • Long-term Growth Theme Investment (Future Technologies):
    • Strategy: High-performance memory like HBM is a core component of various future technologies such as data centers, autonomous driving, and the Internet of Things (IoT). Consider a strategy of diversifying your portfolio across industries related to these long-term growth themes.
    • Potential Risks: Future technologies may not yet be commercialized or may fail in technological development, and excessive stock price increases may occur due to market expectations.
