It was late 2024 when the news cycle finally broke the tension. Advanced Micro-Fabrication Equipment Inc. (AMEC) wasn’t just surviving; it was winning. For anyone watching the messy divorce between U.S. and Chinese tech sectors, the saga of the AMEC China chipmaker delisting threat felt like a never-ending courtroom drama.
Honestly, it’s been a wild ride. One minute, the Pentagon has you on a "blacklist," and the next, you’re suing your way back into the light. If you’ve been following the semiconductor wars, you know AMEC isn’t just any company. They make the etching tools that literally carve the circuits into silicon. Without them, China’s dream of chip self-sufficiency basically grinds to a halt.
The Rollercoaster of the CMC List
Let's get one thing straight: the "delisting" everyone kept whispering about was tied to the U.S. Department of Defense's (DoD) "Chinese Military Companies" (CMC) list. Being on this list is a nightmare for a public company. It’s not a formal delisting from the Shanghai Stock Exchange—where AMEC is actually traded—but it acts as a massive "keep out" sign for U.S. investors.
In January 2024, the DoD slapped AMEC back onto that list. They claimed the company was part of the Chinese military-industrial complex. AMEC’s founder, Gerald Yin—who, by the way, spent decades at Intel and Applied Materials and is a U.S. citizen—wasn't having it. He’s a guy who knows how the American system works.
"We firmly believe that through effective communication and even legal action, the US Department of Defense will correct the wrong decision," the company stated during the heat of the legal battle.
And they did. By December 18, 2024, the Pentagon officially backed down. They removed AMEC from the CMC list after a high-stakes lawsuit filed in the U.S. District Court for the District of Columbia. This wasn't just a win for AMEC; it was a blueprint for other Chinese tech giants.
Why the Delisting Fear Still Lingers in 2026
You might think the drama ended there. Nope. Even though AMEC won its legal battle against the Pentagon, the ghost of the AMEC China chipmaker delisting conversation persists because of the Department of Commerce.

There’s a difference between the "Military List" and the "Entity List." AMEC is still on the Entity List. This means U.S. suppliers still need a special license to sell them high-end parts. It also creates a weird legal gray area for U.S. persons working there. Just look at what happened in late 2024: two key American technical leaders, Ni Tuqiang and Yang Wei, had to resign from their official roles because of U.S. export restrictions. They stayed with the company in "undisclosed" roles, but the message was clear: the U.S. government wants to decouple the brains from the machines.
In early 2026, the landscape has shifted again. China has now enforced a 50% domestic equipment mandate. They are forcing their own chipmakers to buy from guys like AMEC and NAURA. This "Juguo Tizhi" (Whole-Nation System) is basically a response to the delisting threats and sanctions. If the U.S. won't let them play in the global market, China is building its own walled garden.
The Real Impact on Shareholders
If you’re holding 688012 (AMEC’s ticker on the STAR Market), the last two years have been a heart-attack-inducing thrill ride.
- The 2024 Dip: When the CMC listing was announced, shares tanked.
- The Recovery: After the lawsuit victory in December 2024, the stock surged nearly 2% in a single day and hasn't looked back.
- 2026 Reality: As of mid-January 2026, AMEC's stock is trading near its 52-week high of 397 CNY.
The company is pulling in about $1.46 billion in revenue (TTM). They are growing because they have to. Since they can't easily buy ASML’s most advanced lithography machines, they’ve pivoted to something called Self-Aligned Quadruple Patterning (SAQP). It’s a way to "cheat" and make 7nm chips using older tools. AMEC’s etching systems are the secret sauce making that possible.
What Most People Get Wrong About Delisting
Most casual observers hear "delisting" and think the company is going bankrupt. That’s not what happened here. AMEC was never on the New York Stock Exchange. The "delisting" threat was actually about U.S. capital being forced to exit.
Under the 2024 and 2025 National Defense Authorization Acts (NDAA), the rules got even tighter. By June 2026, the DoD is prohibited from buying anything from companies on the CMC list. If AMEC hadn't won its lawsuit to get off that list, every U.S. defense contractor would have had to scrub AMEC-linked hardware from their supply chains. That’s a death sentence for global expansion.
Is AMEC Finally Safe?
"Safe" is a strong word in the semiconductor world.
While AMEC proved it can beat the Pentagon in court, the "Entity List" remains a chokehold. The U.S. is currently looking at "node-agnostic" tools—basically tools that can be used for both old and new chips—to see if they can tighten the screws even more.
But here is the twist: AMEC is now essential. In the 2026 market, they are one of the few companies providing "Virtual 3nm" capabilities through advanced packaging. They aren't just making tools; they are helping China bypass the need for Western lithography entirely.
Actionable Insights for the Path Ahead
If you're navigating the fallout of the AMEC China chipmaker delisting saga, here’s the ground reality you need to act on:
1. Watch the Litigation Trend
AMEC's success has emboldened other firms like Hesai and IDG Capital. If you’re invested in Chinese tech, look for companies that are willing to sue the DoD. It’s no longer a suicide mission; it’s a proven legal strategy.
2. Diverge Between Military and Commerce Lists
Don't panic just because a company is on a "list." Check if it’s the CMC (which affects investment) or the Entity List (which affects supply). AMEC’s stock recovered because it cleared the investment hurdle, even while the supply hurdle remained.
3. Focus on "Bypass" Tech
The real money in 2026 is in companies facilitating "lithography bypass." AMEC’s etching and deposition tools are the primary drivers for SAQP and chiplet architectures. These technologies are the bridge that keeps China in the AI race despite being cut off from the latest Western tech.
4. Domestic Mandate Compliance
China's 50% domestic equipment rule is the biggest tailwind for AMEC right now. Regardless of what the U.S. does, AMEC has a guaranteed customer base in SMIC and other domestic giants. This provides a floor for their valuation that didn't exist three years ago.
The era of AMEC being a "potential" delisting victim is largely over. They’ve transitioned into a cornerstone of a parallel tech ecosystem. It’s messy, it’s political, and it’s definitely not the globalized world we were promised in 2010. But for AMEC, the courtroom win in late 2024 was the moment they proved they could fight back.
Next Steps for Monitoring AMEC:
Verify the latest updates on the Bureau of Industry and Security (BIS) "Entity List" revisions for 2026. While the CMC list is clear, any change in the Entity List status would immediately impact AMEC's ability to procure spare parts for their high-end MOCVD and etching systems. Keep a close eye on the quarterly filings for SSE: 688012, specifically looking for the "Government Grants" section, as this was the original evidence used by the DoD to claim military ties. Managing these regulatory risks is now just as important as the technology itself.
