Core Viewpoint - Samsung Electronics faces increasing pressure to revitalize its competitiveness in the memory chip market, particularly in high bandwidth memory (HBM), which is crucial for advanced AI computing. Establishing a supply agreement with major buyer Nvidia is essential for Samsung [1][2]. Group 1: HBM Market Dynamics - SK Hynix has dominated the HBM market since 2022, supplying Nvidia exclusively with HBM3, while Samsung has not yet passed Nvidia's stringent certification tests. Analysts predict that by 2025, SK Hynix will hold a 57% market share, followed by Samsung at 24% and Micron at 19% [1]. - Samsung's relative weakness in HBM is a key factor in its declining position in the broader DRAM market, where it lost its leadership to SK Hynix for the first time, with market shares of 34% and 36% respectively [2]. - Samsung is focusing on improving its HBM products and aims to pass Nvidia's certification for HBM3E chips, which could open doors for future orders [2]. Group 2: Semiconductor Business Performance - Samsung's foundry division has secured a significant order from Tesla for next-generation AI chips, which may help offset substantial losses in its memory division [3][4]. - The foundry's 2nm process is reportedly achieving expected yields and production stability, with plans for mass production by the end of the year [4]. - The contract with Tesla is seen as a critical achievement, potentially leading to more orders from other major tech companies and improving Samsung's competitive position against TSMC [5]. Group 3: Future Strategies and Expectations - Samsung plans to implement a dual-track strategy to enhance its existing mature process business while accelerating its pursuit of TSMC [6]. - The foundry's strong performance is expected to positively impact Samsung's overall semiconductor results and help restore its memory competitiveness [6]. - Samsung is working on the next generation of HBM (HBM4) and has submitted its sixth-generation DRAM (D1c) for validation, with production expected to ramp up soon [7].

Core Viewpoint - Samsung Display is restructuring its IT business department by adding an IT sales team to prepare for a full-scale launch of its IT OLED business, despite previous poor sales of Apple's OLED iPad [1]. Group 1: Organizational Changes - On July 1, Samsung Display restructured its IT business department, adding an IT sales team alongside the existing IT technology and development teams [1]. - In December 2024, Samsung Display announced that Lee Jong-hyuk, head of the large-size division, would also take on the role of head of the IT division, while Lee Joo-hyung would lead the small-size division [3]. Group 2: Business Focus - The large-size division focuses on producing quantum dot (QD)-OLED panels for TVs and monitors, while the small-size division is responsible for OLED panels for Samsung's Galaxy series and Apple's iPhone [4]. - The appointment of the large-size division head to the IT division is expected to benefit the overall expansion of the IT OLED business, potentially creating synergies despite the differences in technology between QD-OLED and small-size IT OLED [4]. Group 3: Strategic Adjustments - The personnel changes on July 1 also included a swap between the heads of the headquarters planning team and the small-size division planning team, both of which are involved in investment decisions [4].
