Shenzhen Longsys Electronics experienced a sharp intraday rally on Monday, with the stock climbing 12.5% to an intraday high of 695.26 CNY after the company released a pre-announcement for its first-half 2026 results.
The preliminary filing set a range for net profit attributable to shareholders between CNY 9.2 billion and CNY 11.0 billion for H1 2026. That range corresponds to a year-on-year increase of approximately 62,200% to 74,400%, marking one of the most pronounced profit accelerations disclosed recently in China A-shares.
Management attributed the surge in earnings expectations primarily to two operational forces. First, the company reported a sharp rise in downstream demand. Second, Longsys cited globally constrained semiconductor memory wafer capacity. The combination of elevated order flow and tighter wafer availability, the company said, pushed both shipments and margins markedly higher.
Longsys identified several additional, company-specific developments that reinforced investor interest:
- Renewal of long-term wafer supply agreements with major global memory manufacturers, which the company said secures a critical input advantage.
- A technical collaboration with AMD that, according to Longsys, reduced DRAM consumption in edge-AI devices by about 40% through its proprietary SSD and firmware architecture.
- A director share-reduction plan that was fully executed, removing what the company characterized as a near-term overhang on the stock.
The company’s update arrived amid a broadly supportive market backdrop for China’s memory and semiconductor sector. The STAR 50 Index has advanced more than 53% year-to-date, and several memory-related stocks reached all-time highs in late June, highlighting a sector-wide uptrend.
Investor sentiment received additional reinforcement from updated forecasts by global investment banks that point to a significant sequential rise in DRAM contract prices for the third quarter of 2026. Those revised expectations helped fuel buying momentum across memory names heading into today’s session.
Taken together, the profit pre-announcement, the supply and technical arrangements disclosed by Longsys, and the broader sector strength underpinned the stock’s intraday gains. The company’s emphasis on wafer supply security and a collaboration that targets DRAM efficiency positions it as a focal point in conversations about AI-related storage demand and constrained industry inputs.
Clear summary
Shenzhen Longsys Electronics pre-announced H1 2026 net profit of CNY 9.2 billion to CNY 11.0 billion - implying a year-on-year increase of about 62,200% to 74,400% - and cited stronger downstream demand, constrained wafer capacity, renewed wafer supply deals, an AMD technical collaboration reducing DRAM consumption in edge-AI devices by roughly 40%, and the completion of a director share-reduction plan as drivers of the 12.5% intraday share rise to 695.26 CNY.
Key points
- Financial shockwave - H1 2026 net profit guidance of CNY 9.2 billion to CNY 11.0 billion implies an exceptionally large year-on-year increase of roughly 62,200% to 74,400%.
- Operational drivers - increased downstream demand and constrained wafer capacity pushed both volumes and margins higher.
- Strategic supports - renewed wafer supply agreements and a technical collaboration with AMD that reportedly cuts DRAM use in edge-AI devices by approximately 40%.
Risks and uncertainties
- Execution risk - the company’s financial projection is a pre-announcement; actual reported results could differ from the preliminary range.
- Supply dynamics - ongoing wafer capacity constraints are cited as a factor in higher margins and volumes; changes in that capacity environment would affect the company’s cited advantages.
- Market sensitivity - sector-wide price expectations, including forecasts for DRAM contract prices, are influencing investor momentum; revisions to those forecasts could alter market sentiment for memory names.
