Sanan Optoelectronics' actual controller Lin Xiucheng arrested on suspicion of embezzlement and misappropriation of funds

[[**In October 2026, Sanan Optoelectronics' actual controller Lin Xiucheng was arrested on suspicion of embezzlement and misappropriation of funds; his chip empire, built on local resources and high leverage, is now crushed by debt with its shares frozen, and its control and business prospects face reassessment.**

**Key points**

**1. Lin Xiucheng built a chip giant through LEDs and a backdoor listing**

He encountered LEDs in 1999, mass-produced chips in 2003, and completed a backdoor listing in 2008; Sanan's market value peaked above 200 billion yuan, and he was once rated Fujian's richest person.

**2. Expansion relied on local subsidies, state capital and share pledges**

]]

Since the backdoor listing, government subsidies have exceeded 11.3 billion yuan, with state-owned capital in Hubei, Changsha, Chongqing and other places investing more than 20 billion yuan; high leverage supported multiple bases, while also planting hidden debt risks.

**3. LED and silicon carbide cycles turned down, and the company posted its first annual loss**

In 2025, revenue was 17.949 billion yuan, up 11.45%, while net profit attributable to shareholders was a loss of 353 million yuan; overcapacity, price wars, depreciation and declining subsidies continued to erode profits.

**4. The controlling shareholder faces freezing and a restructuring application, control may change hands, and governance is under pressure**

On the evening of October 23, 2026, a brief announcement from Sanan Optoelectronics once again thrust Lin Xiucheng into the spotlight: the company received notice from the family of its actual controller that Lin Xiucheng had been approved for arrest by the procuratorate on suspicion of the crimes of occupational embezzlement and misappropriation of funds. At the close that day, Sanan Optoelectronics' share price stood at 10.10 yuan, with a total market value of approximately 50.4 billion yuan.

At its peak, Sanan Optoelectronics once surpassed a market value of 200 billion yuan and was regarded as a next-generation semiconductor leader with boundless prospects. Its founder, Lin Xiucheng, was also once rated as the richest person in Fujian.

With a single arrest approval announcement, this once ambitious and domineering industrial and capital tide-rider has finally reached the point where the water spilled cannot be gathered again.

Lin Xiucheng's story begins with a pile of scrap iron.

In the 1980s, this young man born in Anxi, Fujian, made his first fortune by buying up scrap steel offcuts from steel mills and reselling them to factories, earning himself the nickname "Scrap Iron King" in southern Fujian.

In 1992, Lin Xiucheng set up Sanan Ironworks as a joint venture with Sanming Steel Works, transforming himself from a middleman into an industrialist. By 2002, Sanan Group's total assets had reached 2.6 billion yuan with about 6,000 employees, ranking 14th among Fujian's top 100 enterprise groups.

Lin Xiucheng never put all his eggs in one basket, and never lingered too long in any single industry.

What truly changed Lin Xiucheng's fate was the 1999 Shenzhen High-Tech Fair.

That was where he first came into contact with LED technology. At the time, the core technology of LED chips was held by American and Japanese companies, and domestically it was almost entirely imported. Optimistic about the prospects, Lin Xiucheng decided to dive in and make locally produced LED chips.

According to media accounts, he personally traveled to the United States to survey the technology, recruited core talent with high salaries, spent heavily on production equipment, and partnered with the American company EMCORE to build a research and industrialization center.

In November 2000, Sanan Electronics was established in Xiamen. In its first three years, the new business accumulated losses of about 600 million yuan, nearly devouring all the profits of the steel segment, yet he still did not stop—and had no intention of stopping.

In 2002, Sanan developed its first epitaxial wafer; in 2003, it achieved mass production of full-color ultra-high-brightness LED chips, breaking the long-standing domestic reliance on imports for LED chips.

During the same period, Sanan also bet on space-grade solar cells. Sanan people at the time vowed to make domestically produced satellites use batteries made in Xiamen. More than two decades later, Sanan's gallium arsenide multi-junction solar cells have indeed been used on commercial satellites.

Meanwhile, Lin Xiucheng, while working in high technology, also stepped into a traditional industry to "test the waters." With a 54% stake, he took control of the Anxi Tea Factory—the country's largest oolong tea factory, whose "Fengshan" premium Tieguanyin was about 70% exported overseas.

A veteran employee of the tea factory later assessed the new boss this way: "He is very shrewd and has a strong head for business."

Three years later, Lin Xiucheng transferred out all of his shares in the tea factory.

In October 2007, Lin Xiucheng began a larger operation. A long-suspended Hubei listed company, *ST Tianyi, had the shares held by its major shareholder forcibly auctioned by a court—the company's predecessor was the laundry detergent brand "Livelihood 28," once famous across the country. Sanan Group spent only 16.781 million yuan to win the 45.43% stake; counting the purchase of bankruptcy reorganization assets and the assumption of debts, the total investment was about 149 million yuan, and thus it borrowed a listed company shell.

In July 2008, Lin Xiucheng completed the injection of Sanan Electronics' LED assets, and *ST Tianyi was renamed Sanan Optoelectronics and resumed trading on the Shanghai Stock Exchange. In just a few years thereafter, the Lin family's paper wealth grew more than tenfold.

The more prominent he became, the less Lin Xiucheng appeared in public.

Industry insiders describe him as "a typical businessman from Anxi in southern Fujian": full of drive, but a man of few words. He rarely gives interviews, and his figure is hard to find even on Sanan's official website.

It was not until November 2012 that Lin Xiucheng first appeared at a public press conference—not in Xiamen, but in Taipei. Facing Taiwanese media, he was reserved and basically answered according to a prepared script; only when the topic turned to talent did he visibly open up.

Putting all kinds of talent to good use—this, too, was the secret to Lin Xiucheng's success in repeatedly crossing industry boundaries.

That trip to Taipei was a footnote to Sanan's climb to the top.

In November 2012, Sanan Optoelectronics announced it would invest 505 million yuan to take a stake in the Taiwan, China LED chipmaker Formosa Epitaxy, holding about 19.9 percent and becoming its largest shareholder—the first time a mainland LED company had taken a stake in a Taiwanese peer.

In Taipei, Lin Xiucheng said that to raise the industry's standing, the first task was to build up economies of scale, and the second was to improve employees' pay and benefits. This money, therefore, "must be spent in Taiwan," so that employees would feel a sense of happiness and only then could there be competitiveness.

At the time, the Taiwanese industry regarded Sanan with both wariness and helplessness: on one hand, they accused it of undercutting prices to win orders and poaching engineers from Taiwanese manufacturers; on the other, they watched its capacity grow ever larger.

By 2017, the MOCVD equipment in Sanan's hands had grown from just over 10 units in 2012 to about 360, accounting for roughly 12% of the global market share, and it was still pushing toward a target of 30%.

International manufacturers such as Samsung and Philips simply handed their chips to Sanan for contract manufacturing and gave up expanding their own production. Because Lin Xiucheng's approach made producing in-house utterly uneconomical for them—and left them no chance of winning.

This scale shock objectively changed the landscape of the global LED industry. Chip prices were driven down sharply, LED lighting and displays became more widely adopted, and China transformed from an importer of LED chips into the world's largest production base.

During this period, Sanan also opened the door for domestic LED chip equipment.

In 2017, Sanan had already installed AMEC's Prismo A7 MOCVD. Lin Kechuang, then general manager of Sanan, publicly commented that AMEC was a partner capable of meeting its advanced technology requirements. As the largest domestic LED chip manufacturer, Sanan's adoption opened a window for domestic MOCVD to gain validation and scale up in a market dominated by international giants.

What supported Lin Xiucheng in rapidly achieving scale was a highly replicable formula: local governments provided land, subsidies, and industrial funds, while Sanan provided projects, production capacity, and jobs.

Under this model, Sanan bases rose one after another in Wuhu, Quanzhou, Changsha, Ezhou, and Chongqing. Among them, the Quanzhou Sanan project had a planned total investment of 33.3 billion yuan (including public supporting facilities); Hubei Sanan's Mini/Micro LED project had a budget of 12 billion yuan; Hunan Sanan's silicon carbide base had a total investment of 16 billion yuan; and the silicon carbide joint venture in Chongqing had a total investment of about US$3.2 billion, with Sanan additionally investing about 7 billion yuan to build a supporting substrate plant on its own.

In the golden age of LED, scale itself was the moat.

Local governments wanted industry, Sanan wanted capital—both sides wanted the same thing, and they hit it off immediately.

According to incomplete statistics from some media, Sanan Optoelectronics has received more than 11.3 billion yuan in government subsidies in total since its backdoor listing. And according to a review by Time Finance, state-owned capital in places such as Hubei, Changsha, and Chongqing has invested more than 20 billion yuan in industrial funds in the Sanan group over the past few years.

At the same time, the shares in the listed company held by Lin Xiucheng were also pledged out again and again in exchange for the cash needed for expansion.

There had long been gray traces along this road as well. Public court documents in the bribery case of Zheng Yunfeng, former executive vice mayor of Xiamen, show that between 2003 and 2010, Zheng Yunfeng accepted property from Lin Xiucheng and provided assistance on matters such as corporate tax rebates and land for headquarters.

What leverage fears most is not the cost, but the cycle turning.

Lin Xiucheng's leverage also quickly pried open enormous trouble.

In recent years, the LED industry has turned sharply, with overcapacity and brutal price wars, and Sanan's core business has been continuously eroded. Silicon carbide, on which great hopes were placed, also ran into the price war brought by a global wave of capacity expansion; the production lines are still ramping up, and depreciation is already weighing on results. On top of that, government subsidies are being phased down, shrinking by hundreds of millions of yuan year after year.

And under the latest wording of “suspected of the crime of occupational embezzlement and misappropriation of funds,” Lin Xiucheng’s capital operations and even his cooperation with local governments are bound to hold other mysteries.

Sanan’s operations therefore continued to deteriorate.

In 2025, Sanan Optoelectronics reported revenue of 17.949 billion yuan, up 11.45% year on year, yet its net profit attributable to shareholders was a loss of 353 million yuan—its first annual loss since its backdoor listing in 2008.

In March this year, as soon as news of Lin Xiucheng being placed under retention came out, Sanan Optoelectronics hit the daily limit-down, losing 24% over five trading sessions. The real chain reaction, however, also occurred at the level of the controlling shareholder: creditors launched risk controls en masse, loan acceleration clauses were triggered, and recovery claims followed one after another.

By October 14, the 1.312 billion Sanan Optoelectronics shares held by Sanan Electronics and Sanan Group had been 100% frozen by judicial order, accounting for 26.30% of total share capital; adding successive freezing orders, the cumulative number of shares subject to successive freezing reached 8.213 billion, equivalent to 625.89% of their holdings. In other words, every single Sanan Optoelectronics share in the Lin family's hands is being watched by queues of more than six rounds of seizure.

In June this year, the individual creditor Lin Suzhen applied to the Xiamen Intermediate People's Court for bankruptcy reorganization of Sanan Electronics and Sanan Group, and withdrew the application on September 2. On October 15, a new reorganization application arrived, this time initiated by Hubei Changjiang Anxin Industrial Investment Fund and Hunan Lugu Development Group.

The investors of that time are now lining up to become creditors.

This is the most intriguing scene in the whole story: the ones applying for reorganization of Sanan's controlling shareholder are precisely the local industrial capital that was once deeply tied to Sanan in Hubei and Changsha.

Expansion bought with pledges must ultimately be settled with control. "Economies of scale must be expanded" made Lin Xiucheng, while the leverage added to scale is now backfiring on the kingdom he built with his own hands.

In July 2017, Lin Xiucheng stepped down as chairman of Sanan Optoelectronics, and his eldest son Lin Zhiqiang took over. Sanan erected an "isolation wall": the founder withdrew from all positions in the listed company, the second generation took charge of the board, and a professional manager system maintained day-to-day operations.

This wall is legally valid. Lin Xiucheng himself holds no position in the listed company, and the announcement did not disclose at which entity the suspected crimes of occupational embezzlement and misappropriation of funds occurred; outsiders cannot and should not directly equate this with a problem of the listed company.

But in reality, Lin Xiucheng never truly went far away.

He has always been the chairman and general manager of Sanan Group; according to reports, in February 2025, when Chongqing municipal leaders met with the president and CEO of STMicroelectronics, the person present alongside them was precisely "Lin Xiucheng, chairman of Sanan Group, and his delegation."

He withdrew from the listed company's roster, but he never left Sanan's gaming table.

The people inside the wall still bear the surname Lin. The chairman is the eldest son, Lin Zhiqiang; the director and deputy general manager is the second son, Lin Zhidong; and the vice chairman and general manager, Lin Kechuang, is Lin Xiucheng's son-in-law.

A Sanan insider said the successor, Lin Zhiqiang, is "as low-key as his father," casual in dress and diet, a man of few words who rarely interacts with employees outside of work.

On the equity side, Lin Xiucheng still holds 59.68% of Sanan Group, and together with Lin Zhiqiang about 71.83%; Sanan Group in turn controls Sanan Electronics. Management was handed to the son, while control remained in the father's hands.

This wall has already been hit hard once this year.

On March 30, Lin Kechuang stated at a press conference that the actual controller's detention was a personal matter unrelated to the company, and announced that he would increase his shareholding together with Lin Zhiqiang. Just one week later, on April 7, he himself was placed under detention and formally investigated by the Yuzhong District Supervisory Commission of Chongqing Municipality. The detention was lifted on October 5, and Lin Kechuang resumed his duties; his shareholding increase commitment was fulfilled on his behalf by Lin Zhiqiang, who cumulatively increased his holdings by 3.57 million shares at a cost of about 49.86 million yuan.

The general manager position was vacant for a full six months, yet the company operated as usual and continued deliveries to customers. From an operational standpoint, this wall withstood the first round of impact. But the operating data show that the pressure never left.

In the first half of this year, Sanan Optoelectronics reported revenue of 6.468 billion yuan, down 28.04% year on year (mainly because revenue from precious metal scrap recycling is no longer recognized; excluding this factor, revenue rose 8.97% year on year); net profit attributable to shareholders was a loss of 98 million yuan, and the loss after deducting non-recurring items was 504 million yuan; inventory write-down provisions alone amounted to 329 million yuan.

Broken down, it is a picture of the old giving way to the new: LED epitaxial wafer and chip revenue was 3.103 billion yuan, up 11.81%, as the legacy business stabilized through price increases and a shift toward high-end products; integrated circuit business revenue was 1.268 billion yuan, down 15.40%, with filters and silicon carbide still the biggest drags on profit.

The new bright spot comes from AI. Sanan's optical chips have established partnerships with 4 of the world's top ten optical module manufacturers; 400G and 800G optical chips are shipping in volume, 1.6T products have been submitted for sample validation, and the company is planning to expand monthly capacity from 2,750 wafers to 4,500 wafers. The silicon carbide joint venture project in Chongqing was announced in March this year to have entered mass production.

As local subsidies gradually recede, the pressure of heavy assets has plunged Sanan into a new predicament: the budget for Hunan Sanan's silicon carbide project was 16 billion yuan, yet cumulative investment had reached 21.163 billion yuan by the end of June, exceeding the budget by more than 30%; the Hubei Mini/Micro display project has been delayed by two years; and of the 7 billion yuan budget for the Chongqing substrate project, only 1.159 billion yuan has been invested.

In semiconductor expansion, large investment is feared, but running out of funds halfway through is feared even more.

Now that Lin Xiucheng has been approved for arrest, Sanan Optoelectronics must answer at least three questions:

First, how will the frozen 26.30% stake be handled? If the court accepts the restructuring, new investors will come in at the controlling shareholder level, and control of Sanan Optoelectronics may change hands. Who the new shareholders are, at what price they come in, and what resources they bring will directly determine where this semiconductor platform goes next.

Second, how will the controlling shareholder's debt be resolved? Some media estimates put the publicly disclosed rigid debt of the Sanan Electronics and Sanan Group system at roughly 12 billion to 15 billion yuan. If this account cannot be settled, it will be difficult for the listed company to fully shake off the "related-party risk" discount in its financing capacity, bank credit lines, and funding arrangements for major projects.

Third, can Lin Zhiqiang prove that the second generation's governance is truly independent? Legal separation is not the same as credit separation. What suppliers, customers, banks, and local governments look at is not just the list of officers in the business registration, but also whether the company can still get orders, get money, and make products once it leaves the founder's relationship network.

Whether the separation wall can hold does not depend on how many times the announcement says "unrelated to the company," but on whether Sanan can earn the money back on its own in the days without Lin Xiucheng.

Lin Xiucheng dared to make a huge bet in a completely unfamiliar industry, and he was "good at" using local and capital forces to keep magnifying that bet. That Sanan could become an important platform for China's compound semiconductors, and that China could transform from an importer of LED chips into a global production base, cannot be separated from this gambling instinct.

But this gambling instinct has piled up a towering balance sheet, and has also stacked layer upon layer of risk onto his own prospects and fate.

After building an enterprise up through "boldness + local resources + capital leverage," how should it be transitioned to the next generation, so that the next-generation enterprise can rely on governance and transparency to last?

This is not Lin Xiucheng's proposition alone, but a hurdle that a large group of people must pass together.
