AI Memory Boom Lifts Biwin; Buyback and Expansion Plans

AI-Driven Profit Surge Biwin swung to a 7.17 billion yuan first-half profit from a year-ago loss, with revenue up 298% and AI edge storage revenue up 434%, as an AI-driven memory upcycle boosted demand.
This is the core fundamental driver of the stock's performance this quarter.
Buyback and Expansion Plans Management proposed a 200–250 million yuan buyback for cancellation and a 4.5 billion yuan advanced packaging expansion, while a subsidiary seeks up to 600 million yuan from outside investors.
These capital actions signal confidence and growth ambitions, supporting the stock.
High Expectations and Valuation Risk The stock had already risen over 165% year-to-date, leaving expectations high and much good news priced in, so any disappointment on storage prices or AI demand could hit shares hard.
This is a key counterweight that could reverse gains if expectations are not met.
Small Buyback Relative to Market Cap The buyback is small relative to the roughly 143 billion yuan market value, limiting its potential impact on the share price.
This tempers the positive effect of the buyback announcement.

Biwin Storage swings to huge profit on AI storage boom, expands capacity

First-half profit swing to 7.17 billion yuan Biwin Storage reported first-half revenue up 298% to 15.6 billion yuan and net profit of 7.17 billion yuan, reversing a year-ago loss.

This is the core fundamental result that validates the bull case and directly supports the share price.
4.5 billion yuan advanced packaging expansion Biwin Storage plans to invest 4.5 billion yuan in a third-phase wafer-level advanced packaging and testing project in Dongguan. This expands capacity for advanced memory packaging, positioning the company to capture more AI-driven demand and supporting future revenue growth.
This is a new, large capital commitment that signals confidence and future capacity, a key driver for the stock.
Share buyback of 200-250 million yuan Biwin Storage intends to repurchase 200-250 million yuan of shares for capital reduction, at a price up to 468.24 yuan per share. This signals management's confidence and can support the stock price by reducing shares outstanding and returning capital to shareholders.
Buybacks are a direct capital action that can lift the stock price and show insider confidence.
Subsidiary raises up to 600 million yuan Biwin Storage's holding subsidiary Guangdong Xinchenghanqi plans to bring in outside investors to raise up to 600 million yuan. This fresh capital can fund expansion and growth without straining the parent company's balance sheet, supporting the subsidiary's development.
This is a new financing event that provides capital for growth, a positive for the company's expansion plans.

Biwin Storage profit explodes on AI storage boom; buyback adds support

First-half profit forecast up over 30x on AI storage demand Biwin guided first-half 2026 net profit to 7–7.5 billion yuan, versus a 226 million yuan loss a year earlier, with second-quarter profit up 41–58% from the first. Management credits the AI computing boom and a strong storage-industry upcycle, plus its own chip-design and packaging investment. That is a huge, concrete jump in earnings, the main force pushing the stock up.
The profit forecast is the core new fundamental driver of the stock.
Chairman proposes 200–250 million yuan buyback for cancellation Chairman Sun Chengsi proposed repurchasing 200–250 million yuan of shares and cancelling them, shrinking the share count and lifting per-share earnings. It signals management confidence and puts a supportive bid under the stock, though the amount is small next to the company's roughly 143 billion yuan market value.
The buyback is a new capital-return action that supports the share price.
Storage industry in a high-growth cycle as AI computing power demand surges The company ties its profit surge to AI computing power exploding and storage entering a high-growth cycle, echoing peers like Lianxun Instruments and Sino Wealth Electronic that also cite AI-driven demand. This shows the driver is industry-wide, not a one-off, which supports the view that Biwin's earnings strength can persist.
It explains the durable industry force behind the earnings jump.
Stock already up over 165% this year, so expectations are high Biwin shares closed at 304.4 yuan on July 15, up more than 165% year-to-date, with a market value around 143.5 billion yuan. The huge run means much of the good news may already be priced in, so any disappointment on storage prices or AI demand could hit the stock hard.
It is the main counterweight: strong gains raise the risk of a pullback.
