- Company allocates $704 million (78% of proceeds) to AI memory R&D
- First-half 2026 revenue jumped 136% to 24.1 billion yuan
- Net profit surged 260-fold to 10.7 billion yuan in H1 2026
- Longsys transitions from memory assembler to branded semiconductor maker
Revenue Surge and Profitability Surge
First-half 2026 revenue hit 24.1 billion yuan, up 136.3% year-over-year. Net profit for the same period reached 10.7 billion yuan, a more than 260-fold increase compared to the prior year. The explosive growth reflects rising demand for memory products across data centers and AI infrastructure.
The company completed its Hong Kong listing on September 8, raising approximately HK$7.08 billion. Founder Cai Huabo retains about 39% ownership through direct holdings and investment vehicles, maintaining significant influence over strategy.
Strategic Pivot to AI Memory
"pour 78% of it into research and development for AI memory chips. That's roughly $704 million earmarked for chip design and next-generation memory products." — Founder Cai Huabo
The move marks Longsys's formal pivot from being a memory module assembler to building its own semiconductor memory brand. Longsys claims the title of the world's second-largest independent memory product maker by revenue, trailing only integrated giants like Samsung and SK Hynix.
Longsys is targeting edge AI storage solutions: memory products designed to work at the point where AI inference actually happens. The company has launched products in this category including a Storage Processing Unit (SPU) controller and AIDIMM modules. These products address a distinct market segment—inference at the network edge and in industrial equipment—rather than competing directly with cloud-scale data center vendors.
Manufacturing and Scale
Longsys has shipped more than 280 million units of its self-designed controller chips, demonstrating manufacturing scale. The company operates manufacturing facilities in Suzhou, China, and an additional plant in Brazil. Longsys acquired Lexar in 2017, giving it a consumer-facing brand to complement its Foresee and Zilia product lines.
The R&D commitment signals confidence in edge AI adoption. Longsys's profitability surge and aggressive capital allocation suggest the company sees sustained demand for specialized memory infrastructure beyond traditional data center applications.
