- Phase 1 (Current): Real demand + irrational valuations = stock bubble
- Phase 2 (Coming): Capacity expansions + new entrants = supply glut
- Phase 3 (Inevitable): Market shakeout = winners and losers emerge
The artificial intelligence boom has supercharged the electronic fabric market—but warning signs are flashing red.
On May 8, 2026, Honghe Electronic Materials (Honghe Keji 宏和科技) dropped a bombshell risk warning.
The company’s stock had skyrocketed 1,286% in just one year.
Its P/E ratio? A mind-bending 418x.
That same day, a newcomer made headlines: Suzhou Jiejie Micro Fiber (Jiejie Weixian 聚杰微纤) announced plans to raise ¥1.1 billion RMB ($152.2 million USD) for an aggressive entry into the high-end electronic fabric market.
The contrast is stark.
One company is screaming about overvaluation while another is charging headfirst into the space.
Here’s what’s really happening in the AI-driven electronic fabric sector—and why both moves matter to investors watching the Chinese tech landscape.
The 418x P/E Ratio Problem: When Stock Price Divorces Reality
Let’s start with the actual numbers behind that insane valuation.
Honghe Electronic Materials (Honghe Keji 宏和科技) isn’t a tiny startup.
In 2025, the company generated:
- Revenue: ¥1.171 billion RMB ($162 million USD) — up 40.31% year-on-year
- Net profit: ¥202 million RMB ($27.9 million USD) — up a staggering 785.55% year-on-year
That’s solid growth, right?
Now look at Q1 2026—this is where things get wild.
In just three months, the company posted:
- Revenue: ¥442 million RMB ($61.2 million USD) — up 79.72%
- Net profit: ¥140 million RMB ($19.4 million USD) — up 354.22%
Here’s the kicker: Q1 2026’s profit alone represents nearly 70% of the entire company’s annual profit for 2025.
The company is printing money because AI servers are consuming massive quantities of specialty electronic fabrics, and those products carry gross margins of 61.31%.
But even with this explosive earnings trajectory, the stock price has grown even faster than the fundamentals.
From May 29, 2025, to May 8, 2026, Honghe’s stock rocketed up 1,286%—resulting in that infamous 418x P/E ratio.
Compare that to the industry average of 69.86x.
That’s a 6x multiple above the sector benchmark.
The company’s warning message was clear: the core business hasn’t changed.
Honghe still manufactures electronic-grade glass fiber fabric—the fundamental building block for Printed Circuit Boards (PCBs).
They’re still focused on R&D and production.
But here’s what they emphasized: the small external float makes the stock susceptible to irrational speculation.
Translation: when fewer shares are available to buy, it doesn’t take much capital to move the stock price dramatically.
The Contagion Effect: How One Stock Pumped the Entire Sector
Honghe’s surge didn’t happen in a vacuum.
Riding the coattails of the electronic fabric excitement, other players in the space saw massive gains between May 29, 2025, and May 8, 2026:
- China Jushi (Zhongguo Jushi 中国巨石): +230%+
- Sinoma Science & Technology (Zhongcai Keji 中材科技): +230%+
- CPIC Fiberglass (Guoji Fucai 国际复材): +230%+
- Feilihua (Feilihua 菲利华): ~200%
- Shengyi Technology (Shengyi Keji 生益科技): ~200%
When one stock in a sector experiences that kind of return, money flows into the entire industry on the assumption that all players will benefit.
It’s classic sector rotation, amplified by AI hype.
The problem?
Not all companies in the space have the same fundamentals or growth trajectory.

Enter the Disruptor: Suzhou Jiejie’s Risky Cross-Industry Bet
On the same day Honghe issued its risk warning, Suzhou Jiejie Micro Fiber (Jiejie Weixian 聚杰微纤) announced an aggressive move into electronic fabrics.
Until recently, Jiejie was a domestic leader in ultra-fine composite fabrics—a completely different market.
But in February 2026, they decided to pivot.
First, they acquired Anhui Genyin Technology to gain a foothold in electronic fabrics.
Three months later, in May 2026, they announced plans to raise ¥1.1 billion RMB ($152.2 million USD) for a new high-end electronic fabric production facility—with a target to complete it in just 12 months.
Let’s talk about why this is ambitious (and risky).
Problem #1: Shaky Financial Performance
Jiejie Micro Fiber (Jiejie Weixian 聚杰微纤) is entering this market from a position of weakness, not strength.
- 2025 Revenue: ¥577 million RMB ($79.8 million USD) — down 3.68% year-on-year
- 2025 Net Profit: ¥56.18 million RMB ($7.77 million USD) — down 12.82% year-on-year
- Q1 2026 Revenue: Down 5.51%
- Q1 2026 Net Profit: ¥10.40 million RMB ($1.44 million USD) — down 29.33%
Their core business is contracting, which makes the aggressive expansion into a new market segment look like a Hail Mary pass rather than a calculated strategic move.
Problem #2: Electronic Fabric Is Capital & Tech Intensive
This isn’t like entering a new market segment where you can leverage existing expertise.
Electronic fabric production requires:
- Massive capital expenditure for specialized equipment
- Extreme precision in manufacturing processes
- Rigorous certification from downstream customers (Copper Clad Laminate and PCB manufacturers)
- Certification cycles that typically last 1-2 years
Jiejie lacks industry accumulation and deep customer relationships.
That’s a massive disadvantage in an industry where trust and proven reliability are paramount.
Building yield on new production lines and achieving profitability in this environment is notoriously difficult—even for established players.
Problem #3: The Equipment Supply Chain Gamble
On April 17, 2026, Jiejie announced plans to purchase Toyota air-jet looms from Toyota Tsusho (Zhushi Huishe Fengtong Jixie 株式会社丰通机械) for up to ¥150 million RMB ($20.75 million USD).
These looms are essential equipment for producing high-end fabric.
The catch?
Delivery timelines are uncertain, and the industry consensus is that current lead times stretch 18-24 months.
A company pledging to build a production facility in 12 months while ordering equipment with 18-24 month lead times is operating on wishful thinking.

The Incumbent Giants Are Already Moving (Much Faster)
Here’s what makes Jiejie’s timeline even more problematic: established players are already accelerating their own capacity expansions.
China Jushi (Zhongguo Jushi 中国巨石): In March 2026, they ignited their Huai’an production line with massive capacity—100,000 tons of electronic yarn and 390 million meters of fabric.
These are numbers that dwarf small new entrants.
Sinoma Science & Technology (Zhongcai Keji 中材科技): Planning to raise ¥4.5 billion RMB ($622 million USD) for low-dielectric fiber fabric projects—3x what Jiejie is raising.
CPIC Fiberglass (Guoji Fucai 国际复材): Also boosting capacity.
Shengyi Technology (Shengyi Keji 生益科技): Ramping up production.
And then there are the vertically integrated plays:
Kingboard Laminates (Jiandao Jicengban 建滔积层板) and Shengyi Technology (Shengyi Keji 生益科技) are expanding internal fabric production to ensure supply chain security.
These companies have existing customer relationships, proven manufacturing expertise, and the financial firepower to out-execute newcomers.

The Supply-Demand Equation Is Shifting (Fast)
Here’s the core economic reality: a single AI server uses significantly more PCBs and electronic fabric than traditional servers.
That’s why demand has exploded.
Currently, high-end specialty fabric is in short supply due to:
- Equipment bottlenecks (limited capacity for specialized looms)
- Long certification cycles (1-2 years with customers)
But here’s the problem: low-to-mid-end fabrics are already facing risks of overcapacity and price wars.
As more capacity comes online—which it will in 2026 and beyond—the market dynamics will shift.
The timeline matters:
- Through end of 2026: High-end supply remains tight (but not for long)
- 2027 onward: New capacity from incumbents and entrants will hit the market
- Mid-tier segment: Already facing pressure from oversupply
Consider Sinoma’s stated goal: increase market share in specialty fiber fabrics from 20% to 30%.
That’s not a 10% increase in total market share—that’s consolidation, where they’re taking share from competitors.
In a market with expanding capacity, that’s a sign of intensifying competition, not demand growth.
The Bubble Question: Is AI-Driven Electronic Fabric Overheated?
Let’s synthesize what we’re seeing:
On one side: Legitimate AI-driven demand is pushing spectacular growth for companies in the space.
Honghe’s 785% earnings growth in 2025 and 354% growth in Q1 2026 are real.
On the other side: Valuations have divorced from fundamentals, creating a 418x P/E ratio that screams speculation.
The sector is experiencing a classic boom-cycle pattern:
- Phase 1 (current): Real demand + irrational valuations = stock bubble
- Phase 2 (coming): Capacity expansions + new entrants = supply glut
- Phase 3 (inevitable): Market shakeout = winners and losers emerge
The companies that will survive and thrive are those with:
- Genuine technological moat: Proprietary processes and know-how
- Established customer relationships: Trust and proven reliability
- Financial discipline: Not overextending into risky expansions
- Scale advantages: Lower costs through established production lines
The companies that will struggle are those that:
- Enter the market from weakness (like Jiejie)
- Bet on aggressive timelines they can’t achieve
- Lack deep industry expertise and customer moats
- Rely on irrational valuations to fund expansion
For investors: the current moment is less about “is there a bubble?” and more about “who survives the bubble bursting?”
Honghe’s risk warning wasn’t panic—it was realism.
The company knows its valuation is disconnected from fundamentals, and it’s being honest about it.
That kind of transparency is rare in bull markets.
Jiejie’s aggressive expansion, meanwhile, looks like chasing a trend with borrowed time and borrowed money—a strategy that historically doesn’t age well.
The electronic fabric sector will absolutely benefit from AI-driven demand for years to come.
But the winners will be the incumbents with moats, not the entrants betting the farm on 12-month timelines and equipment with 18-24 month lead times.
Key Takeaways: Navigating the AI-Driven Electronic Fabric Market
- Valuations are stretched: A 418x P/E ratio is 6x above industry averages—sustainable? Unlikely.
- Earnings are real: But they’re growing slower than stock prices, creating an unsustainable gap.
- Capacity is coming: New facilities from incumbents will shift the supply-demand equation by 2027.
- Competition will intensify: Market share battles (not total market growth) will dominate the next phase.
- New entrants face structural headwinds: Long certification cycles and limited customer relationships make cross-industry pivots risky.
- The shakeout is coming: Only companies with real moats and financial discipline will thrive through the cycle.
The AI-driven electronic fabric boom is real.
The bubble pricing is also real.
Investors and founders should focus on which companies will win the next phase of competition—because someone will, and those bets matter far more than betting on the sector as a whole.
