YMTC Holdings Sells XMC Stake as Optics Valley State Capital Takes Over Wuhan Chip Assets
N.R. Finch
YMTC Holdings sold its 39% stake in Wuhan Xinxin Semiconductor (XMC) to Optics Valley Semiconductor Investment, lifting the buyer's holding to 47.88% and making it the new controlling shareholder — a move widely seen as clearing the path for YMTC's A-share IPO.
What exactly is being split apart?
YMTC Holdings sold its entire 39% stake in XMC to Wuhan Optics Valley Semiconductor Industry Investment, exiting XMC completely.
Optics Valley Semiconductor's combined holding rises to 47.88%, replacing YMTC Holdings as XMC's controlling shareholder.
This means → two companies that once sat inside the same group have now completed a full separation of business and equity.
Why split now?
In May 2026, YMTC filed its IPO coaching registration with the China Securities Regulatory Commission, formally launching pre-listing preparations.
At the same time, XMC withdrew its listing application from the Shanghai STAR Market.
In plain terms = if two affiliated companies pursued IPOs simultaneously, regulators would scrutinize related-party transactions, asset ownership, and governance independence — a clean split now removes that obstacle.
How is XMC performing on its own?
Net profit attributable to shareholders fell from RMB 717 million in 2022 to RMB 201 million in 2024; first-half 2025 profit shrank further to roughly RMB 7.12 million.
In late 2024, XMC was added to the U.S. Entity List, restricting access to certain equipment and technology.
This means → XMC's profitability has been declining steadily, and sanctions have further narrowed its room to expand — the new shareholder is not inheriting an easy asset.
What value does XMC still hold?
XMC operates central China's first 12-inch wafer fab, offering foundry services at 40 nm and above.
Applications span industrial control, networking equipment, consumer electronics, and MCUs — microcontroller units, the small chips that run simple device functions.
In plain terms = XMC does not chase leading-edge nodes, but in NOR flash — a type of memory chip prized for fast reads in automotive and industrial uses — and specialty-process foundry work, it remains one of China's few mature production lines.
Why is Optics Valley state capital stepping in?
The new controlling shareholder, Wuhan Optics Valley Semiconductor Industry Investment, was established under Hubei Science & Technology Investment Group and serves as the core platform for semiconductor development in Wuhan's East Lake High-Tech Zone.
In recent years the Optics Valley system has been steadily building positions across specialty processes, power semiconductors, compound semiconductors, and memory-related supply chains.
This reflects a systematic effort by Wuhan's local state capital to consolidate regional semiconductor assets — taking control of XMC is the latest move on that board.
Where does each company go from here?
YMTC Holdings will focus on 3D NAND flash — the high-capacity storage chips most widely used in smartphones and data centers — along with R&D and capital-market execution, aiming for a standalone A-share listing.
XMC returns to the local state-capital system, concentrating on NOR flash and specialty-process foundry services.
This means → whether the two companies can break through independently on their respective tracks is the key test of whether this split was worth it.
