How a Sheet Metal Company Became the World's Third-Largest PCB Maker Through Strategic Acquisitions

Suzhou Dongshan Precision Manufacturing has transformed itself from a traditional metal processor into a global electronics powerhouse through aggressive M&A. Now it's seeking a Hong Kong IPO to fund even more deals, but mounting debt raises questions about whether its acquisition playbook can keep working.

Buy What You Don't Have

There's a simple philosophy at work inside Suzhou Dongshan Precision Manufacturing Co. Ltd.: If you don't have it, just buy it.

That approach has taken the company on quite a journey. Starting out in 1980 as Dongshan Sheet Metal, the business spent decades as a traditional metal processor before deciding it wanted a piece of the consumer electronics action. Now, after a series of strategic acquisitions over the past decade, it's become the world's third-largest supplier of printed circuit boards, the ubiquitous components that make modern electronics possible.

Last week, the company filed an application for a Hong Kong IPO, hoping investors will buy into its acquisitive story. The company already trades in Shenzhen, but it's looking to Hong Kong to raise additional funds for its ongoing shopping spree. With five advisors enlisted for the potential offering, led by UBS and Chinese brokerage heavyweight Citic Securities, the company hasn't disclosed how much it wants to raise. But that kind of advisory firepower typically signals a substantial deal, likely north of $100 million.

The timing makes sense. Dongshan has kicked its acquisition playbook into overdrive this year, announcing two major deals that will push it into optical communications and automotive components. As those purchases come due, fresh capital would certainly come in handy.

From Metal Bender to Circuit Board Giant

The transformation really began in 2016, when Dongshan paid $600 million for Mflex, a U.S.-based company specializing in flexible printed circuits. These bendable circuit boards show up in smartphones, tablets, and other portable devices where space is tight and components need to fold or flex. It was the breakthrough the company had been seeking into consumer electronics.

Two years later, Dongshan doubled down with the $293 million acquisition of Multek, a rigid printed circuit board business that had been part of contract manufacturer Flextronics. With that deal, the company could suddenly produce all major types of PCBs.

The strategy worked spectacularly. PCBs have essentially replaced Dongshan's original business. In the first half of 2025, the PCB segment generated 11 billion yuan (around $1.5 billion) in revenue, representing 65% of the company's total sales. The old precision metal components and castings business? That's down to just 13.9% of revenue now.

According to third-party research cited in the company's prospectus, Dongshan ranked as the world's second-largest supplier of flexible printed circuits and third-largest in overall PCB shipments last year. That second-place FPC ranking translates to a hefty 23.8% market share. The overall third-place position, though, represents just 4.8% of the total PCB market, which gives you a sense of just how massive and fragmented this industry really is.

Growth Amid Fierce Competition

Dongshan's overall revenue grew 2.4% to 17 billion yuan in the first half of 2025, up from 16.6 billion yuan a year earlier. Not exactly explosive growth, but profit performance was more impressive, jumping 39% to 758 million yuan from 560 million yuan over the same period. Still, the relatively thin margins reflect the brutal competitive dynamics of the PCB business.

And the competition is fierce. Chinese companies now produce the majority of the world's PCBs, but that doesn't mean it's an easy market. According to recent research from Shenzhen Enterprise Investment, 43 PCB companies were listed on China's A-share markets as of April, many trading on the tech-focused Shenzhen exchange. The sector is crowded with players like Victory Giant Technology, Shennan Circuits, and WUS Printed Circuit all fighting for market share.

Within its PCB business, Dongshan focuses primarily on flexible circuits used in mobile devices like smartphones and laptops, which accounted for 84% of total PCB sales during the first half of 2025. It's a huge market, but also a relatively mature one where differentiation is tough and pricing pressure is constant.

The Next Chapter: AI and Automotive

Given that competitive reality, Dongshan is once again reaching for its acquisition playbook to diversify. In June, the company announced it would acquire Taiwan-based Source Photonics in a deal worth 5.9 billion yuan (roughly $815 million). Source Photonics makes optical transceivers, the components that enable high-speed data transmission in data centers and telecommunications networks. For Dongshan, it's an entry ticket into the optical communications sector.

That deal followed another major acquisition announced in May, when Dongshan agreed to pay 100 million euros ($115 million) for Groupe Mécanique Découpage, a French manufacturer of automotive components.

The Source Photonics acquisition is particularly interesting because it positions Dongshan to ride the AI wave. The explosion in AI applications has driven surging demand for AI servers and the infrastructure needed to handle massive data processing workloads. Those AI servers need optical transceivers like the ones Source Photonics makes, and they also need sophisticated PCBs. The potential synergies could help Dongshan build relationships to sell higher-end circuit boards into this fast-growing segment.

Sensing the opportunity, Dongshan announced in July that it would invest up to $1 billion to build high-end PCB facilities in Zhuhai, near Macao in South China, and also in Thailand. The high-end server market is genuinely driving much of the PCB industry's growth right now, so the strategic logic is sound.

The Debt Question

But here's where things get complicated. All this aggressive expansion and acquisition activity comes with a price tag, and Dongshan is increasingly paying that price through debt.

The company's debt-to-asset ratio has remained persistently high, generating substantial financial expenses that eat into profits. According to filings with the Shenzhen Stock Exchange, Dongshan's short-term debt reached a staggering 98.36 billion yuan (more than $13 billion) by the end of the third quarter of 2025. That's up 35% from the end of 2024.

Think about that for a moment. The company's short-term debt alone is now more than five times its total revenue for the first half of the year. That's a lot of financial pressure, especially for a business operating in a highly competitive industry with relatively modest margins.

The massive $1 billion investment in new PCB facilities, while strategically sound, only adds to the concern. The company is essentially betting it can grow its way out of its debt burden by capturing a larger slice of the high-end AI server market. That might work, but it also means Dongshan is doubling down at a time when its balance sheet is already stretched.

Market Reaction and Valuation

Chinese investors have been enthusiastic about Dongshan's story. The Shenzhen-listed stock is up 133% so far this year, a spectacular run by any measure. But even after that surge, the shares trade at a forward price-to-earnings ratio of just 17, the same multiple as competitors like Victory Giant and WUS Printed Circuit. That relatively muted valuation reflects the market's recognition that the PCB industry, despite pockets of growth in areas like AI servers, remains competitive and mature.

The company clearly views strategic M&A as one of its core competitive advantages, even touting it in the IPO prospectus as a proven playbook for growth into new areas. And to be fair, the track record supports that claim. The acquisitions of Mflex and Multek genuinely transformed Dongshan from a traditional sheet metal processor into a global PCB powerhouse.

Can the Formula Keep Working?

But past success doesn't guarantee future results, especially when you're moving into entirely new sectors like optical communications and automotive components. These businesses operate under different dynamics and present fresh management challenges. Integrating acquired companies is hard enough. Integrating them while simultaneously managing a massive debt load and investing $1 billion in new production capacity is significantly harder.

The upcoming Hong Kong listing should provide some breathing room by bringing in fresh capital. But it won't solve the fundamental question facing Dongshan: Can the company execute its ambitious expansion without overextending itself financially?

Investors considering the Hong Kong IPO will need to weigh the company's proven acquisition track record against the very real risks of its current strategy. Moving into so many new business areas so quickly, while carrying such significant debt, is a high-wire act. Dongshan has successfully walked that wire before, but the height keeps getting higher and the safety net keeps getting thinner.

The company's management clearly believes in the strategy. The question is whether investors in Hong Kong will share that confidence, particularly given the more conservative valuation multiples that similar companies command in the market. At 17 times forward earnings, Dongshan isn't getting much credit for its growth story despite the impressive stock performance in Shenzhen this year.

For now, the acquisition playbook continues. But with mounting debt, ambitious expansion plans, and entry into unfamiliar markets, Dongshan is testing the limits of its own formula. The Hong Kong IPO will be an important test of whether international investors believe the company can pull it off.
