- Total approved guarantee quota for the company is 11 billion yuan. Outstanding guarantees come to 5.81 billion yuan.

Class A shares of Shenzhen Longsys Electronics Co., Ltd. will resume trading Monday, following a late-Friday disclosure from the memory products manufacturer announcing fresh guarantees for its overseas subsidiaries.
This isn’t an earnings update. Still, it drops into a market now scrutinizing cash demands, debt levels, and offshore exposure among China’s rapidly revalued chip names.
The timing is key for Longsys. The filing reveals parent-company guarantees remain a major prop for the group’s funding—this, despite Longsys running procurement and manufacturing outside mainland China.
Longsys, in its filing, said it’s backing a 100 million yuan loan for its Hong Kong subsidiary, with a joint-and-several guarantee, the funds coming from Postal Savings Bank of China’s Qianhai branch. The company also revealed that Zilia Eletrônicos, under its control, capped a $9 million guarantee tied to a standby letter of credit—essentially a bank’s promise to cover payments—for Zilia Semicondutores in Brazil. That guarantee covers the period from Jan. 28, 2026, through Feb. 18, 2027. Following these disclosures, Longsys put its total external guarantee quota at 11 billion yuan, or 170.08% of its latest audited net assets. The outstanding guarantee balance, as of the filing, was 5.81 billion yuan, or 89.78%, and the company reported no overdue guarantees.
The company said all the guarantees cover subsidiaries already consolidated in its financial statements. According to the company, these new guarantees remain under limits that were previously authorized, so there was no requirement for another board or shareholder vote.
Longsys slipped 4.72 yuan to finish Friday at 288 yuan, trading in a tight 285-to-292.46 yuan range. While the semiconductor sector picked up 1.16% that day, Longsys trailed, even before the filing appeared. 1

Investors are watching to see if these guarantees remain just another standard funding tactic—widespread among Chinese corporate groups—or if they begin to hint at a squeeze on working capital, as the company juggles overseas procurement and ramps up manufacturing capacity.
One risk isn’t hard to spot. Longsys flagged that its guarantees top 100% of audited net assets, with a bigger chunk tied to businesses carrying heftier leverage. If financing costs jump, exchange rates swing, or demand for memory products falters, that could turn into a real squeeze.
Looking past individual corporate moves, traders are eyeing macro data next week that could jolt sentiment around pricey tech names. China drops its January CPI and PPI numbers on Wednesday, Feb. 11. Two days later, on Friday, Feb. 13, markets will get a look at new yuan loans, M2 money supply, and total social financing, all per Trading Economics. 3
Everything starts with Monday’s open. The focus then shifts to inflation and credit data—traders want to see if those numbers move sentiment around China’s chip and storage stocks. Later in April, Longsys is due to report; its results could finally shed some light on where things stand with cash flow and funding needs.
