The first half of 2026 saw one of China's "Five Storage Dragons" and a leading memory module manufacturer, Longsys, deliver a financial performance report rarely seen in the A-share market, capturing significant attention from the capital markets.
The company announced this past Friday that it anticipates its net profit for the first half of 2026 to skyrocket by 600 to 744 times compared to the same period last year. This represents a leap from a net profit of less than 15 million yuan a year ago to a potential high of over 10 billion yuan.
In terms of secondary market performance, if measured from its post-IPO low of 46.52 yuan per share touched in October 2022 to its high of 749.88 yuan per share on July 1, 2026, Longsys has accumulated a gain of over 1500%.
Understanding the Company's Business
Longsys is not a traditional "memory giant" like Samsung or Yangtze Memory Technologies, lacking their wafer fabrication capacity. However, it is the world's second-largest and China's top independent memory module leader. It is deeply involved across the entire chain of memory chip design, packaging & testing, and brand sales, standing out as one of the few domestic companies in the memory industry that has moved beyond low-end assembly and possesses core in-house R&D capabilities.
From an industry chain perspective, Longsys operates at a core midstream position. It sources memory wafers from top-tier manufacturers upstream like Samsung, SK Hynix, Micron, and Yangtze Memory Technologies. Downstream, it covers a full spectrum of applications including consumer, industrial, automotive-grade, and server markets, building a dual-brand, comprehensive product portfolio.
Different from typical assembly factories, Longsys's core competitive edge lies in its integrated in-house R&D of memory modules and packaging & testing. The company independently develops SPU storage controller chips and HLC intelligent caching architecture, which effectively reduces memory consumption in AI endpoint devices and adapts to on-device AI computing demands. Simultaneously, it has built its own high-end SiP packaging and testing base in Suzhou, achieving self-sufficiency in chip packaging and testing, completely breaking reliance on external foundries. This forms a complete business model of "wafer procurement + in-house design + self-controlled packaging/testing + global sales," which is the foundation of its ability to navigate industry cycles beyond pure contract manufacturing.
The company's FORESEE brand targets industrial, automotive, and embedded B2B markets, while its Lexar brand focuses on the high-end consumer retail market. This dual-brand strategy allows it to capitalize on both industrial necessities and consumer market opportunities.
The company's core products are divided into four major segments. Embedded storage is the foundation, accounting for over 40% of revenue, widely used in smartphones, security equipment, industrial IoT, and new energy vehicles. It is a core domestic supplier of automotive-grade storage, deeply integrated with mainstream domestic automakers and smart hardware manufacturers. Solid-state drives, portable storage, and memory modules follow closely, strategically positioned in the PC, AI server, and consumer electronics sectors.
Decoding the Massive Profit Surge
The staggering 600-fold-plus increase in net profit for the first half of 2026, according to consolidated institutional views, results from a confluence of AI-driven benefits and bold counter-cyclical inventory accumulation.
First is the红利 from the AI-driven super-cycle in memory. The 2026 explosion in global AI computing capital expenditure, coupled with the widespread adoption of AI PCs, AI servers, and autonomous driving devices, has created massive, inelastic demand for storage. Concurrently, major manufacturers like Samsung, SK Hynix, and Micron had cut capital expenditure and reduced capacity for two consecutive years prior, leading to a severe shortage of wafer supply. Data from TrendForce shows that DRAM contract prices rose over 60%, and NAND flash prices rose over 55% in the first half of 2026. The industry's supply-demand gap continued to widen, pushing product prices into a steep upward trajectory.
Second is the massive price differential红利 realized from the counter-cyclical inventory strategy led by the founder. During the industry-wide downturn of 2024-2025, when memory particle prices hit a 15-year low, Longsys dared to heavily accumulate vast quantities of low-priced memory wafers against the trend, completing large-scale stockpiling at the industry's bottom.
Consolidating institutional research reports, Longsys's inventory at the end of Q4 2025 and Q1 2026 was 11.678 billion yuan and 17.961 billion yuan, respectively, representing sequential increases of 95.8% and 53.8%. Against the backdrop of extremely tight supplier capacity and shortages across almost all memory categories, the company's ability to stockpile so rapidly was predicated on first renewing LTAs (Long-Term Agreements) and MOUs (Memorandums of Understanding) with several original manufacturers, deeply locking in core supply chain resources.
The company's large-scale counter-cyclical stockpiling during the industry trough, followed by a significant rise in memory prices, transformed low-cost inventory into high profits. However, this hoarding also tied up substantial capital, resulting in negative operating cash flow for five consecutive years, with a net outflow of 2.875 billion yuan in Q1 2026.
Finally, the premium brought by in-house technology widens the gap with peers. Unlike pure assembly manufacturers, Longsys's self-developed controller chips and intelligent caching architecture give its products exclusive advantages in AI scenarios. According to institutional research, this contributes to gross margins 8 to 12 percentage points higher than ordinary module products. Combined with cost reductions from its own packaging and testing base, the company's profit elasticity far exceeds that of its peers, enabling a multiplier effect on profits during the industry upcycle.
The Founder's Journey
Many wonder about the origin of the company's name, "Jiangbolong" (江波龙). The character "Jiang" (江) is taken from the name of founder Cai Huabo's twin sister, Cai Lijiang. "Bo" (波) comes from the founder's own name, Cai Huabo, marking the core founding entity and witnessing the shared growth of the individual and the enterprise. "Long" (龙), meaning dragon, stems from the fact that both siblings were born in the Year of the Dragon in 1976.
The accompanying English brand, Longsys, facilitates international communication, allowing this Shenzhen-rooted local enterprise to reach global markets and become a representative name in China's domestic memory industry.
In 1996, 20-year-old Cai Huabo went south to Shenzhen, immersing himself in the Huaqiangbei electronics market. Starting from basic electronic component sales, he gained a deep understanding of the industry's channel dynamics and cyclical logic.
In 1999, he and his twin sister Cai Lijiang pooled their startup capital, rented a 10-square-meter counter, and officially embarked on their entrepreneurial journey. Unlike entrepreneurs from capital market backgrounds, Cai Huabo embodies the quintessential traits of a Huaqiangbei merchant: pragmatic,敏锐, willing to take calculated risks, and possessing极强的 resilience.
An early experience with inventory hoarding taught him the potential profit prospects from the extreme volatility of the memory industry. In 2002, misjudging the market, Cai stocked up on large quantities of the冷门的 Hitachi AG-AND flash memory. Just as the goods were滞销 and the cash flow濒临断裂, an unexpected opportunity arose: Apple's iPod sparked a NAND flash craze, causing an instant market shortage and a跟着紧缺 supply of USB flash drives. Cai then repurposed the积压的 flash memory into USB drives, selling them out as "affordable alternatives."
The first cyclical gamble brought Longsys险中得利. However, merely two years later, the memory industry experienced a产能井喷 and a cyclical downturn. The spot price for 256Mb NAND chips plummeted from $30 at the beginning of the year to $12, causing massive paper losses for Longsys. Cai Huabo then tasted the bitterness of the cycle.
Experiencing the绞杀 of cycles and witnessing others become overnight millionaires only to lose their wealth just as quickly instilled a deep sense of insecurity in Cai Huabo regarding纯贸易型业务. He resolved to gradually shift the company towards manufacturing.
A "Snake Swallowing an Elephant" Transformation
After the 2008 financial crisis, the company began transitioning to OEM manufacturing. In 2011, Longsys finally fired the first shot for its own brand, launching the FORESEE storage brand targeting the enterprise market.
This was already the 12th year since Longsys's founding. At 35, Cai Huabo was for the first time truly宣告 his presence in the market with a proprietary brand.
After its launch, FORESEE passed rigorous testing by state-owned enterprises like State Grid and CRRC Group with its excellent performance and secured large orders from companies like BYD and Transsion Holdings.
However, Cai Huabo's vision extended beyond the present. While gaining recognition in the B2B market, this was only half the battle in the storage industry. The other vast half—the consumer market—remained an area where Longsys had little presence.
The opportunity finally arrived in 2017 when Longsys, at an undisclosed price, acquired the high-end consumer storage brand Lexar from memory giant Micron Technology.
At that time, Lexar's annual sales were $400 million, nearly three times Longsys's revenue that year. This "snake swallowing an elephant" deal sent shockwaves through the industry, with质疑声接踵而至: "Who is Longsys?" "Does it have the capability to manage Lexar well?" "Will Lexar's quality decline?"
After the acquisition was finalized, Cai Huabo implemented大刀阔斧的改革 on Lexar. He promptly shut down the US factory, transferred production capacity to the Zhongshan manufacturing base, invested over 200 million yuan to build the Lexar Quality Lab, and integrated its self-developed caching acceleration algorithms into the product line.
The effects of these measures were立竿见影. In the four years following the acquisition, Longsys's annual revenue surged from 4.228 billion yuan to 9.74 billion yuan, an increase of over 1.3 times, achieving a significant revenue跨越.
Founders' Wealth Approaches 100 Billion Yuan
In August 2022, Longsys was listed on the Shenzhen Stock Exchange's ChiNext board with an issue price of 55.67 yuan per share and a market capitalization of approximately 23 billion yuan.
With cash from the IPO, and having tasted the benefits from previous acquisitions, the company embarked on a new round of M&A. In 2023, it acquired a 70% stake in Suzhou Yuancheng Technology (a semiconductor packaging and testing company) for $131.6 million, followed by acquiring an 81% stake in Brazil's leading memory manufacturer Zilia (智忆) for approximately $164 million.
Through these series of actions, Longsys vertically expanded from its memory module base into multiple industry chain segments including controller chips, firmware development, and packaging & testing.
As of the close on July 3, 2026, Longsys shares were quoted at 618.02 yuan per share, with a total market capitalization reaching 261.5 billion yuan. Siblings Cai Huabo and Cai Lijiang collectively hold 177 million shares, representing 41.78% of the total share capital, with a stock value as high as 97.6 billion yuan.
In the 2026 Hurun Global Rich List, Cai Huabo, with a wealth of 52 billion yuan, became the richest person from Jiujiang, Jiangxi. The combined wealth of the Cai siblings also made them the third-wealthiest family in Jiangxi, following Chen Tianshi of Cambricon and Zou Zhinong of TFC Optical Communication.
Concluding Remarks
Looking back at Longsys's explosive growth path, the 600-fold profit surge is not mere luck but the inevitable result of two decades of industry深耕, precise cyclical博弈, and continuous technological iteration. This homegrown enterprise from Huaqiangbei has witnessed the transformation of China's memory industry from import dependence and low-end代工 to self-sufficiency and global competition.
However, behind the极致 cyclical红利, risks are never far away. Ten billion yuan worth of inventory is a profit amplifier but also a potential minefield for impairment. Cyclical红利 can create temporary神话; only through technological深耕 and稳健经营 can a company navigate the industry's bull and bear cycles.
