Fabless
Chinese name: 乐鑫信息科技（上海）股份有限公司 (Yuèxīn Kējì)
The only Chinese fabless with genuine global developer-ecosystem dominance (Wi-Fi MCU #1 worldwide) — FY2025 revenue ¥25.65亿 (+27.8%), net ¥4.98亿, overseas revenue +40.4%. H1 2026 (interim 30 July): revenue ¥14.81亿 (+18.9%) with net profit ¥3.34亿 (+27.9%) and record 49.3% gross margin — Q2 was the first-ever >¥8亿 quarter; management also announced a ¥50–100m share buyback for equity incentives. Product cadence stayed fast: ESP32-E22 tri-band Wi-Fi 6E (CERTIFIED 6E mark obtained in Q2) and the ESP32-S31 dual-core RISC-V SoC (sampled May, in mass production since July); Wi-Fi 7 capability is targeted by mid-2027. Its pivot to fully self-developed RISC-V cores removes the last foreign-IP dependency across its mainstream line.
What does this firm design?
Wi-Fi/BLE/Thread connectivity SoCs and MCUs with self-designed RISC-V CPUs, plus modules/devkits (M5Stack majority-owned).
