Taiwan's microcontroller unit (MCU) designer Holtek Semiconductor posted consolidated revenue of NT$754 million (US$24.53 million) for the third quarter of 2025, up 10% from a year earlier, bringing January through September 2025 revenue to NT$2.375 billion, a 31% annual increase. The company maintained a solid gross margin of around 38% and aims to reach 40% in the near term.
Net profit attributable to the parent company jumped 137% year-over-year to NT$27.14 million in the third quarter of 2025. For the January through September 2025 period, net profit totaled NT$140 million, representing a 192% surge and a return to profitability from losses a year earlier. The rebound highlights Holtek's improving operations and stronger cost discipline.
MCUs lead revenue as inventory levels improve
In the first nine months of 2025, MCU sales contributed NT$1.82 billion, representing 77% of total revenue. Shipments of microcontroller ICs reached 309 million units, up 25% from the previous year.
Holtek also continued to optimize inventory, reducing stock levels to NT$1.05 billion by the end of September 2025, equivalent to 19% of total assets—a steady improvement from last year.
Security, health, and BLDC segments gain ground
Holtek's product mix continued to diversify in 2025. Security products saw the strongest growth, expanding their revenue share from 5% to 17% year-over-year. Health products contributed 13%, down slightly from 15%, while brushless DC motor (BLDC) applications grew from 2% to 3%.
Security segment shipments surged 215% year-over-year to 39 million units in the first three quarters of 2025, boosted by mass production of wireless smoke alarms for US customers. A new product line is set to enter volume production in the fourth quarter of 2025, expected to sustain momentum into 2026.
Meanwhile, health and wellness product shipments rose 17% to 36 million units. The company plans to step up development of continuous glucose monitoring (CGM) devices next year, although lengthy certification processes may delay market entry. Holtek also aims to strengthen its presence in the Indian market for health applications.
For BLDC motor applications, shipments rose 175% to 11 million units. Holtek is transitioning server cooling fan solutions from ASIC-based to MCU-centric designs, with 12V models in production and 48V versions under development. Although current revenue contribution is modest due to long certification cycles, early customer adoption is expected to attract new clients and boost future sales.
Navigating trade uncertainty and expanding into energy storage
Looking ahead, Holtek expects steady growth in its security and health product lines through 2026, but remains cautious about short-term order visibility, which currently extends only about three months. Some customers advanced orders in the second quarter of 2025 to avoid potential tariff impacts, leading to an earlier-than-usual sales peak.
The company acknowledged lingering uncertainty over US–China trade negotiations but remains hopeful that progress following the October 30, 2025, meeting between US and Chinese leaders in South Korea could help stabilize market sentiment.
To capture growing energy storage demand, Holtek has launched cabinet power solutions ranging from 120W to 1,000W, covering inverters, energy storage systems, battery management systems (BMS), and solar maximum power point tracking (MPPT) applications. The company also plans to introduce new bidirectional inverter products to broaden its energy portfolio.
