From Startup to Global Powerhouse in 5 Years
Hangzhou-based CoreMega Semiconductor has filed for a Hong Kong IPO, marking a meteoric rise for China’s latest power semiconductor unicorn. Valued at $3.4 billion (RMB 22B), the company—founded in 2019—has become a key player in power management ICs (PMICs) and gallium nitride (GaN)/silicon carbide (SiC) power devices, supplying giants like Samsung, Xiaomi, LG, BYD, and CATL10.
As someone who has tracked China’s semiconductor boom, I’ve rarely seen a firm scale this fast. CoreMega’s secret? Aggressive M&A, deep R&D, and heavyweight backers—including Sequoia China, Hillhouse, Xiaomi, CATL, and China’s National IC Fund II. Their 2020 acquisition of Korean PMIC firm SMI (for $330M) was a masterstroke, instantly granting global reach and 40+ patents26.
Why Power Semiconductors Matter
Power chips are the “invisible backbone” of EVs, AI servers, and smartphones—regulating voltage, minimizing energy loss, and boosting efficiency. The global market will hit $115B by 2029 (7.1% CAGR), with China accounting for 40%+ demand8. CoreMega’s two-pillar strategy covers:
✔ PMICs (90% of revenue): Used in phones (Xiaomi/OPPO), displays (BOE), and EVs (CATL’s battery systems)
✔ Power Devices (SiC/GaN MOSFETs): Critical for 800V EV fast-charging and data centers
The “Fab-Lite” Playbook: How CoreMega Outpaced Rivals
1. Acquisition-Driven Growth
Most Chinese chip firms struggle to go global—but CoreMega’s 2020 SMI buyout changed the game:
- Gained Samsung/LG as anchor clients
- Secured Korean-optimized PMIC designs (critical for OLED displays)
- Added Dr. Huh Youm (ex-SK Hynix VP) as CTO6
2. R&D at Scale ($300M+ Invested)
Despite revenue dips (more later), CoreMega prioritized R&D:
🔹 150+ patents (60+ for GaN/SiC)
🔹 4B+ PMIC chips shipped in 2024 (vs. 5B power devices)
🔹 First Chinese firm to mass-produce 100V GaN FETs for Xiaomi’s 120W fast chargers
3. Strategic Backing from Tech Titans
CoreMega’s cap table reads like a “Who’s Who” of Chinese tech:
- Xiaomi/CATL: Secured PMIC supply for phones/EVs
- National IC Fund II: Endorsement as a national champion
- Sequoia/Hillhouse: Betting on China’s “power chip independence”6
Financial Snapshot: Growth Pains Before IPO?
| Metric | 2022 | 2023 | 2024 |
|---|---|---|---|
| Revenue (RMB) | 16.88B | 16.40B | 15.74B |
| Gross Margin | 37.4% | 33.4% | 29.4% |
| Adjusted Net Profit | 237.9M | 76.9M | (53.3M) |
Data: CoreMega’s HKEX filing (2025)28
Key Challenges
⚠ Client Concentration: 61.4% revenue from top customer (rumored to be Samsung)6
⚠ Price Wars: Competing with TI, Infineon, and domestic rivals squeezed margins
⚠ R&D Costs: 25.8% of revenue in 2024 (vs. industry avg. ~15%)
Yet, the post-IPO roadmap looks promising:
✅ Expand SiC/GaN production (for EV/industrial markets)
✅ Acquire European/US chip firms (per HKEX filing)
✅ Cut reliance on Korean clients via Xiaomi/CATL deals
China’s Semiconductor IPO Wave: Why Now?
CoreMega isn’t alone—2025 is China’s “Semiconductor IPO Year”:
🚀 Moore Threads (GPU): Filed for $1.5B Shanghai IPO
🚀 Muxi (AI chips): Prepping dual-track (A+H) listing
🚀 Nexperia (SiC): Eyeing Hong Kong debut
Two macro trends fuel this rush:
1️⃣ Geopolitics: US/Japan/EU export controls force China to “de-risk” chip supply chains
2️⃣ Policy Support: Beijing’s “Little Giant” fund now backs 1,000+ domestic IC firms8
From my visits to Shenzhen/Hangzhou fabs, I’ve noticed VCs now prefer “fab-lite” models like CoreMega’s—owning design/IP while outsourcing wafer production. It’s capital-efficient yet still qualifies for state subsidies.
The Bottom Line: Can CoreMega Become China’s Infineon?
CoreMega’s IPO is a litmus test for China’s power semiconductor ambitions. Success hinges on:
✔ Diversifying beyond PMICs (SiC/GaN gross margins can hit 50%+)
✔ Leveraging CATL/Xiaomi to penetrate EV/smart home markets
✔ Using HKEX listing as a springboard for global M&A
My take: While short-term margins worry investors, CoreMega’s tech stack and client roster make it a long-term bet on China’s chip self-sufficiency. If they execute well, this Hangzhou unicorn could join SMIC/Huawei HiSilicon as national champions.
