Longsys Electronics forecasts 600-fold profit surge in H1 2026
Synopsis
Key Takeaways
Shenzhen Longsys Electronics, one of China's largest memory module manufacturers, has forecast a net profit of between 9.2 billion yuan (US$1.36 billion) and 11 billion yuan for the six months ended June 30, 2026 — a year-on-year jump of between 62,204 per cent and 74,394 per cent — as a global memory-chip upcycle supercharges the mainland's downstream storage sector.
The numbers behind the forecast
According to the company's preliminary earnings disclosure released on Friday evening, net profit attributable to shareholders is expected to soar from just 14.8 million yuan in the same period a year earlier to as much as 11 billion yuan. Revenue is projected to reach between 22 billion yuan and 25 billion yuan, up from 10.2 billion yuan in H1 2025, reflecting a near-doubling of the company's top line alongside the extraordinary margin expansion.
Market reaction
Shares of Longsys surged 12.5 per cent on the Shenzhen bourse on Monday morning, trading at 695.25 yuan as of around 10am. The rally spilled over into the broader Chinese storage sector: Shenzhen-listed CEAC International hit its 10 per cent daily limit, while Shanghai-listed Biwin Storage Technology gained 3.7 per cent.
Why it matters
The company attributed the dramatic improvement to stronger downstream demand and constrained growth in global memory wafer capacity, which it said had created a favourable pricing environment across the semiconductor memory industry. Longsys also disclosed that it had renewed wafer supply agreements — including long-term contracts and memorandums of understanding — with several major global memory wafer suppliers, securing resources for future production cycles.
The competitive backdrop
The forecast reinforces a broader pattern: China's memory supply chain, spanning DRAM and NAND segments, is capturing outsized gains from a global storage rebound driven in large part by artificial intelligence workloads. Surging demand for AI applications has tightened supply and lifted pricing across the industry, benefiting downstream integrators such as Longsys alongside upstream wafer producers including ChangXin Memory Technologies and Yangtze Memory Technologies Corp. Solid-state drive and storage controller chip makers are also riding the same tailwind.
What's next
Investors and industry analysts will be watching whether Longsys can sustain these margins once the full H1 2026 results are audited and published, and whether the renewed wafer supply agreements translate into stable input costs as competition for memory capacity intensifies globally. The trajectory of AI-driven storage demand through the second half of 2026 remains the single biggest variable for the entire Chinese memory supply chain.
