Market Environment for Storage ICs

  1. Rising demand for high‑performance memory
  • On 5 November 2025, SK Hynix announced that it had completed price and volume negotiations with Nvidia for next‑year HBM4 supply, with the HBM4 price expected to exceed HBM3E by more than 50 %.
  • The same day, U.S. storage‑chip indices surged: Seagate and Western Digital rose over 10 %, Micron nearly 9 %, and NetApp more than 5 %.
  1. Price pressure in DDR5 DRAM
  • A supply disruption in October 2025, triggered by Samsung Electronics’ pause on DDR5 contract pricing, led to a 25 % jump in spot DDR5 prices within one week.

  1. Sector performance in China
  • On 3 November, the Chinese “storage‑chip” index rebounded after a two‑day decline, with major constituents such as Aerospace Intelligent Equipment and Taiji Industrial posting significant gains.
  • On 4 November, the “AI PC” concept index fell 2.49 %, reflecting broader volatility in technology‑related stocks.

Implications for Shenzhen Techwinsemi

  • Product relevance – Shenzhen Techwinsemi’s core products—flash memory master chips and memory‑card control ICs—are integral to the broader memory ecosystem that is experiencing heightened demand from AI, cloud computing, and consumer electronics sectors.
  • Competitive landscape – The company operates in a segment that includes both domestic and international players. While the sector is experiencing price appreciation for advanced memory technologies, Shenzhen Techwinsemi’s focus on flash and control ICs positions it to benefit from the sustained need for high‑density storage solutions.
  • Valuation context – The negative price‑earnings ratio suggests that the market has not yet fully priced in growth expectations for the company. However, the sector’s recent rally and positive outlook for storage demand provide a backdrop that may support future valuation improvement.

Outlook

The storage‑chip market is entering a new pricing cycle, driven by supply constraints and accelerating AI workloads. Shenzhen Techwinsemi’s product portfolio aligns with this trend, offering potential upside as demand for flash and control ICs continues to rise. The company’s strong domestic presence and specialized expertise in flash memory manufacturing provide a foundation for capturing growth within the expanding Chinese memory market.
