ActRO Advanced Process Solutions Re-Rating Report
Analyzing the cash cow in mobile camera actuators together with automation and inspection-equipment growth
0. Bottom line first
ActRO appears to be trying to re-rate from a smartphone camera actuator supplier into an advanced process-solutions company by adding automation equipment, six-axis inspection, terahertz non-destructive inspection, and graphene coating equipment.
Official fact: The source gives 2025 third-quarter cumulative revenue of KRW 182.6 billion, operating profit of KRW 4.5 billion, a year-over-year swing to profit, and automation/inspection-equipment revenue rising from KRW 2.9 billion to KRW 18.0 billion, up 5,223%.
Interpretation: The key is not only that sales are growing but that revenue quality is changing. If high-margin equipment revenue attaches to component revenue, operating margin can step up.

1. Evolution: owning both components and equipment
ActRO was founded in 2012 and focused on mobile camera actuators. The key turning point was the May 2016 merger with Wintech. The source says this internalized both component design/manufacturing and production-equipment capability inside one company.
Interpretation: Process know-how from components feeds equipment development, and equipment improves component quality and yield. That circular structure is ActRO's moat.
2. Vietnam production bases
First site in Vinh Phuc
Established in 2015 near Samsung Electronics and Samsung Electro-Mechanics Vietnam sites, producing OIS Main Actuator and Folded Zoom Actuator at scale.
Second site in Phu Tho
Established in 2019 as a capacity-expansion base and dedicated line for high-value Folded Zoom Actuators.
R&D and difficult equipment
Korea focuses on R&D, sales, and high-difficulty equipment, while Vietnam handles mass production.
3. Mobile actuators: still the cash cow
The source says mobile actuators still generated about 90% of revenue as of Q3 2025. ActRO is specialized in difficult technologies such as folded zoom and OIS, not only simple autofocus.
| Technology | Content | Investment point |
|---|---|---|
| Folded Zoom | Uses periscope optics to bend light and enable high-magnification optical zoom | Requires difficult optical alignment and prism control, creating a high entry barrier |
| OIS | Moves lens or sensor in the opposite direction to stabilize images | Video demand and adoption in mid/low-end models expand the TAM |
| Customer diversification | Samsung Electro-Mechanics tier-1 vendor, Galaxy S/Z, Google Pixel, Xiaomi, Vivo, Oppo | Potential reduction in single-customer dependence |
4. Equipment business: the core transition

The central investment point is equipment-business expansion from 2024-2025. The source says ActRO signed an approximately KRW 8.0 billion OIS process automation equipment contract with actuator maker J in December 2024, the largest single equipment contract in company history.
It also describes in-house folded-zoom performance inspection equipment and six-axis inspection equipment being applied to global customer mass-production lines. The six-axis system detects tiny errors across six degrees of freedom during OIS and zoom operation. Supply visibility to a North American smartphone customer is treated as a diversification and credibility catalyst.
5. THz and graphene: expansion into batteries and semiconductors
The longer-term re-rating variable is whether ActRO can move beyond smartphones into battery and semiconductor process equipment.
Terahertz inspection
0.1-10THz electromagnetic waves are described as harmless compared with X-rays and able to penetrate plastics, ceramics, and paper.
Separator/electrode inspection
The system targets real-time, non-contact full inspection of separator thickness, density, and porosity.
Silicon anode coating
Based on technology transferred from the Korea Institute of Energy Research, ActRO is developing equipment to coat silicon particles with graphene to reduce swelling.
For semiconductors, the post points to THz inspection for voids and cracks inside advanced packages and for glass-substrate processes. For batteries, it mentions joint development and testing with a global separator company and possible revenue contribution from 2026.
6. Financial outlook
Official fact: 2025 Q3 cumulative revenue was KRW 182.6 billion, up 29% year over year, and operating profit was KRW 4.5 billion, turning profitable. Equipment revenue rose from KRW 2.9 billion to KRW 18.0 billion, up 5,223%.
| Period | Source outlook | Meaning |
|---|---|---|
| 2025 | Revenue about KRW 242.1 billion, operating profit KRW 6.1 billion | First year of meaningful equipment contribution |
| 2026 | Revenue KRW 262.5 billion, operating profit KRW 13.2 billion | Reflects THz, North American equipment supply, and actuator volume growth |
7. Risks and conclusion

- Smartphone-cycle dependence: slower foldable growth could limit actuator growth
- New-equipment adoption delays: customers may be conservative about adopting THz and other new process tools
- Chinese competition: technology catch-up and price pressure remain threats in mobile components
The core is a hybrid model that combines actuator stability with growth in inspection and automation equipment. In 2026, sustained equipment revenue, THz references, and six-axis inspection supply to North American customers will be the practical re-rating indicators.
