The operation may have seemed modest compared to other major acquisitions in the sector, but it has ultimately become another high-level political warning. Sanan Optoelectronics and its Malaysian partner Inari Amertron have abandoned their $239 million offer to acquire the Dutch company Lumileds after the Committee on Foreign Investment in the United States (CFIUS) concluded that the deal posed “unresolvable risks to U.S. national security.” The withdrawal was formalized on April 17th.
This decision carries more weight than the amount suggests. Not only because it blocks the purchase of a European company by a Chinese group, but because it confirms that Washington continues to treat certain segments of the semiconductor industry as a red line— even when the target company is not strictly American. Lumileds is a Dutch firm, yes, but with a global business, a strong industrial presence, and operational footprints in the United States.
A deal that falters for the second time in ten years
It wasn’t the first time Lumileds became a geopolitical battleground. In 2016, Philips had to cancel the sale of 80.1% of Lumileds and Automotive to a consortium led by Go Scale Capital after failing to overcome CFIUS objections. Philips’ annual report from that year explicitly stated: despite efforts to mitigate U.S. regulators’ concerns, approval was not granted, and the deal was terminated.
Years later, Philips sold that same 80.1% stake to funds managed by Apollo Global Management, and Lumileds continued its corporate journey until entering Chapter 11 bankruptcy in August 2022. The company confirmed in October of that year that its reorganization plan had been approved by the court, affecting both Lumileds U.S. and the Dutch entity. This detail helps explain why Washington can intervene so decisively in a transaction that, on paper, involves a European company.
The new attempt was announced in August 2025, when Lumileds reported that Sanan Optoelectronics and Inari Amertron agreed to acquire 100% of the company. The transaction was presented as the next step in Lumileds’ transformation, with closure expected in the first quarter of 2026, subject to usual regulatory approvals. That schedule will no longer be met.
Lumileds and Sanan operate precisely in the area that most displeases Washington
CFIUS has not publicly provided a detailed technical explanation for its decision. However, the industrial context helps to understand why the operation was problematic. Lumileds is not just a lighting brand: it is a global provider of LED and microLED technology for automotive, displays, lighting, and mobile devices, with over 3,500 employees across more than 15 countries. Additionally, part of its catalog relies on compound semiconductors based on InGaN, i.e., gallium nitride with indium, a technology family related to one of the most sensitive materials in today’s market.
Sanan, on the other hand, is not a newcomer or a small company. Its corporate documentation describes it as a group focused on semiconductor materials, epitaxy, chips, and devices, with presence in various countries and specific activity in GaN RF, GaAs, and other advanced compounds. In other words, the operation connected not just a Chinese LED manufacturer with a European lighting firm, but two significant players in a segment increasingly seen as strategic, not just industrial.
Therefore, this case fits into a broader pattern. In 2016, the White House blocked the acquisition of Aixtron’s U.S. business by Chinese buyers, concluding the deal threatened national security. In 2017, Cree ended its sale of Wolfspeed to Infineon, admitting it couldn’t find ways to satisfy CFIUS objections. In both previous cases, Washington made it clear that certain technologies related to compound semiconductors, power, or RF could not be regarded as merely interchangeable industrial assets.
A blow to Sanan’s outward expansion
The withdrawal also comes at a difficult time for Sanan. According to the South China Morning Post, the company stated that the failed deal would not materially impact its finances or daily operations and that it would maintain its internationalization strategy. However, the blockade adds to months of particular difficulty for the group, marked by investigations into its leadership and judicial freezes on holdings linked to the founding family, as reported by Caixin Global.
This context further complicates the interpretation of the move. For Sanan, the Lumileds purchase was not just about business expansion but a way to gain more presence in high-value segments of the global LED, advanced lighting, and compound semiconductor markets. For Washington, however, it was seen as an uncontrollable risk. The outcome is the same as a decade ago: the transaction collapses, and political messaging outweighs industrial reasoning.
Europe should also take note
The European perspective is also significant. Lumileds is a Dutch company, but its sale was decided in Washington. This reality demonstrates how many tech operations are increasingly influenced not solely by the laws of the country where the company is headquartered but by the actual jurisdiction over patents, subsidiaries, assets, and activities in the U.S. For Europe, which is growing more vocal about technological sovereignty, this episode raises an uncomfortable question: how much real control does it have over companies deemed strategic when the final decision can still be outside its borders?
What happened with Lumileds is not just corporate news. It is another indication that the technological war extends beyond the most advanced AI chips. It also involves materials, processes, and seemingly more modest companies, embedded in supply chains that Washington considers sensitive. In that landscape, even a European firm can end up becoming a piece on a board it does not fully control.
Frequently Asked Questions
Why can the U.S. block the purchase of a Dutch company like Lumileds?
Because the deal involved assets and activities with a U.S. nexus. Lumileds confirmed in 2022 that its Chapter 11 process affected both its U.S. and Dutch entities, which explains CFIUS’s jurisdiction over the transaction.
Is this the first time CFIUS has blocked a Lumileds sale to a Chinese buyer?
No. In 2016, Philips had to cancel the sale of 80.1% of Lumileds and Automotive to a consortium led by Go Scale Capital due to lack of CFIUS approval.
What technology makes Lumileds particularly sensitive?
Lumileds operates in LED and microLED sectors, using InGaN, a family of compound semiconductors based on gallium nitride. Although CFIUS has not provided a detailed technical explanation, industry context helps understand the sensitivity of such cases.
What impact does this setback have on Sanan?
The company claims the failed deal will not materially affect its finances or daily operations, but the block complicates its international growth strategy, especially during a time of internal pressure on its corporate governance.
