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.

Renesas sells timing unit, quake hits plants, launches new AI memory chip

Renesas completes sale of timing business to SiTime Renesas sold its timing business to SiTime, which had about 70% gross margin and $300M annual revenue, mostly from AI data centers. This frees up cash but removes a profitable, fast-growing unit. The CEO joining SiTime's board and a planned collaboration on MEMS resonators could create future opportunities, but the net effect on Renesas's value is unclear.
This is a major strategic move that changes Renesas's business mix and could affect future growth and profitability.
Kumamoto earthquake halts production at two Renesas plants A magnitude 7.1 earthquake on July 29 forced Renesas to suspend operations at its Kawashiri and Nishiki plants for cleanroom inspections. No injuries were reported, but wall cracks and water leaks occurred. This disruption can delay chip shipments, raise costs, and hurt sales if it lasts, which is negative for the stock.
The earthquake directly disrupts Renesas's manufacturing, threatening near-term revenue and supply.
Renesas resumes Nishiki plant, aims to restart Kawashiri by Aug 5 Renesas quickly resumed production at its Nishiki plant and targets restarting the Kawashiri plant by August 5. This fast recovery reduces the negative impact of the earthquake. While other semiconductor plants in the region remain shut, Renesas's ability to bounce back quickly is a positive sign for its operations and customer confidence.
The speed of recovery limits the damage from the earthquake, which is positive for the stock.
Renesas launches Gen 3 MRDIMM chipset for AI data centers Renesas announced a third-generation DDR5 MRDIMM chipset that boosts memory bandwidth by 25% to 16,000 MT/s, designed for AI data centers. It is sampling to all major DRAM suppliers, with production in late 2027. This strengthens Renesas's position in the growing AI infrastructure market, which could drive future revenue and profit.
This new product targets a high-growth market and shows Renesas's technological leadership, supporting future earnings.
