Puya's profit surge on AI memory demand; sector pullback a risk

First-half profit to jump ~1,925% on AI memory demand Puya expects H1 2026 net profit of about 825 million yuan, up 1,925% from a year earlier. Revenue is seen at 3.95 billion yuan, up 336%. The company credits AI data-center build-out, which lifted both prices and sales volumes of its general-purpose memory chips, plus growing sales of new analog products like MCUs and drivers.
This is the core new fundamental driver that explains why the stock is moving and gives investors the big picture.
AI infrastructure and Beijing AI-agent push support demand Global AI computing build-out is driving memory chip demand. On July 24, Beijing introduced measures to accelerate AI agents, encouraging general-purpose processors and inference chips. This policy support reinforces the long-term demand outlook for Puya's memory and analog chips used in AI and industrial applications.
It shows a broader, policy-backed demand tailwind that supports the positive earnings story.
PBOC injects 500 billion yuan, easing market liquidity The People's Bank of China conducted a 500 billion yuan one-year medium-term lending facility operation on July 24. This adds cash to the financial system, which can support stock market sentiment and make it easier for growth companies like Puya to access funding. Lower funding stress generally helps share prices.
It is a new macro liquidity event that can lift the whole market, including Puya.
Memory chip sector pullback dragged Puya down 11% On July 13, the memory chip sector tumbled, with Puya falling over 11% in a broad market selloff. This shows the stock is still sensitive to sector-wide swings and profit-taking, even as its business fundamentals improve. Investors should expect sharp short-term moves alongside the positive earnings trend.
It provides a fair counterweight, showing the stock is not immune to sector volatility.

GigaDevice surged on profit jump, then slid on memory selloff

Profit surge and strategic stakes GigaDevice forecast a first-half profit jump of over 1,000%, driven by memory-chip shortages, its stake in CXMT's Shanghai IPO, and China's carbon-peak plan boosting chip demand.
This was the main positive catalyst that initially drove the stock higher.
Memory selloff and overcapacity fears The stock then slid amid a global memory selloff and overcapacity fears, with GigaDevice dropping 10% in a broad tech rout, highlighting its exposure to volatile sector sentiment.
This was the key negative force that reversed the early gains.
Chairman buyback and stake increase Sentiment later improved as Chairman Zhu Yiming proposed a 1–2 billion yuan buyback for cancellation and increased his stake, signaling insider confidence.
This insider action helped stabilize and lift the stock after the selloff.
DRAM expansion and LPDDR4 production The company expanded DRAM investment and prepared LPDDR4 mass production, supporting its long-term growth prospects in the memory market.
This fundamental development underpins future revenue potential.

GigaDevice slides on memory selloff, then chairman's buyback and DRAM plans lift it

Memory-stock selloff drags GigaDevice down A global memory selloff hit the sector: Demingli fell limit-down twice and US memory names dropped over 8%, with GigaDevice among leading decliners. Worries that memory price rises are slowing and that chip supply may outrun demand pushed the stock down.
Explains the main downward force on the stock this period.
Overcapacity fears spark broad chip selloff Chinese stocks hit a one-week low as investors worried about semiconductor overcapacity and huge AI spending. The STAR 50 fell 6.3% and GigaDevice dropped 10% in the broad tech selloff, showing how sector-wide sentiment, not company news, can move the stock.
Shows a second, market-wide negative driver hitting the shares.
Chairman's buyback and stake increase signal confidence Chairman Zhu Yiming proposed buying back 1-2 billion yuan of shares for cancellation and raising his stake by at least 1 billion yuan, while pledging no sales for 12 months. Cancelling shares lifts earnings per share and signals insiders see the stock as cheap.
This is the biggest new positive catalyst for the stock.
DRAM expansion and new LPDDR4 product near mass production GigaDevice is injecting 500 million yuan into its Zhuhai subsidiary for a DRAM project, and says niche DRAM prices keep rising on shortages, with its own LPDDR4 chip about to enter mass production and LPDDR5 in development. That points to future sales growth.
Shows the company's own growth pipeline beyond the buyback.

GigaDevice profit surge and CXMT IPO lift chip shares

First-half profit to jump over 1,000% on memory chip shortage GigaDevice expects first-half net profit of about 6.9 billion yuan, up roughly 1,099% from a year earlier, as tight memory chip supply lifted both sales volumes and prices, with microcontroller shipments also growing. This is the core reason the stock hit its daily limit up.
The profit forecast is the main fundamental force behind the move and is new this period.
CXMT Shanghai IPO bookbuilding boosts GigaDevice as shareholder Bookbuilding began for ChangXin Memory Technologies' Shanghai listing, and GigaDevice, as a CXMT shareholder, jumped 10% as part of a broad semiconductor rally. The stake gives GigaDevice a direct link to China's memory-chip expansion.
This is a separate, new catalyst driving the stock beyond its own earnings.
Carbon-peak plan targets energy storage and EVs, lifting chip demand The State Council's 15th Five-Year Carbon Peaking Action Plan sets 2030 goals for energy storage and new energy vehicles, which should raise demand for the memory and microcontroller chips GigaDevice sells into those sectors.
A new policy driver that supports future demand for GigaDevice's products.
Profit surge partly from investment gains, not only chip sales Part of the profit jump came from fair value gains on securities investments, which are less predictable than chip sales. The memory shortage driving prices and volumes is the durable force, but the investment gains add a one-off element investors should weigh.
Gives the fair counterweight that not all of the profit surge is from core operations.
