HPSP(403870) Analysis: High-Pressure Annealing Equipment Monopoly Structure and 2026 Earnings Trajectory
HPSP is the world's only mass-production supplier of high-pressure annealing (HPA) equipment for semiconductor processes, listed on KOSDAQ. The company maintained an operating profit margin of 50.5% in Q1 2026 — even during the off-season — and is positioned for sequential quarterly earnings improvement in the second half as its customer base expands.
1. Company Overview and Core Business
HPSP (403870) is a KOSDAQ-listed company specializing in the manufacture of High-Pressure Annealing (HPA) equipment used for film-defect healing in semiconductor processes. Foreign ownership stands at 30.60%, with the largest shareholder being Hit2025 Holdings Co., Ltd. (20.46%). In Q1 2026, the company recorded revenue of KRW 31.9 billion (≈$21.3M) and operating profit of KRW 16.1 billion (≈$10.8M), achieving an operating profit margin (OPM) of 50.5%; EPS of KRW 292 (≈$0.20) beat the market consensus of KRW 257 (≈$0.17) by 13.8%. On an annual basis, building on 2025 revenue of KRW 173.0 billion (≈$115.7M) and operating profit of KRW 89.9 billion (≈$60.1M) (OPM 52.0%), 2026 revenue of KRW 240.2 billion (≈$160.7M) and operating profit of KRW 129.6 billion (≈$86.7M) (OPM 53.9%) are projected.*1
📌 1Q26 OPM 50.5% — Profitability maintained above 50% even in the off-season; EPS beat consensus by 13.8%
2. Core Product Competitiveness Analysis
HPA equipment is seeing broader adoption across logic and foundry segments driven by tightening film uniformity requirements as process nodes shrink (2/3/4nm). Revenue from logic/foundry-facing equipment is projected to grow from approximately KRW 90 billion (≈$60.2M) in 2025 to KRW 124.4 billion (≈$83.2M) in 2026.*1 The NAND customer base is set to expand from 1 in 2025 to 4 in 2026 and 5 in 2027, marking broad entry across major NAND suppliers.*2 Looking ahead, high-pressure oxide film equipment (currently in Beta testing) and Hybrid Bonding process applications represent mid-term product diversification pathways.
| Category | Details |
|---|---|
| Position | World's sole mass-production supplier of High-Pressure Annealing (HPA) equipment |
| Competitive Advantage | 50%+ operating margins, supply across logic and memory applications, ongoing annual expansion of customer base |
| Competitive Disadvantage | Concentration in a single core product, quarterly volatility tied to the leading customer's capex cycle |
3. Valuation Analysis
As of May 17, 2026, at a share price of KRW 52,200 (≈$34.9), Trailing PER of 60.0x, Forward PER of 40.0x, and PBR of 13.70x are applied. The decline in Forward PER relative to Trailing PER (60x → 40x) reflects the earnings recovery outlook toward a 2026 EPS of KRW 1,416 (≈$0.9).*1 Although 2025 EPS of KRW 870 (≈$0.6) declined from the prior year's KRW 1,040 (≈$0.7), quarterly earnings growth is expected to resume from 2026 onward.*1 Target prices from major securities firms are distributed in the KRW 60,000–65,000 (≈$40.1–$43.5) range,*3 and the premium to the average Fwd P/E of global semiconductor equipment peers is attributable to the company's monopolistic supply position and profitability level.
📌 A Forward PER of 40x reflects the earnings growth recovery outlook, though it remains elevated in absolute terms within the sector
| Metric | Current | Sector Avg. | Interpretation |
|---|---|---|---|
| Trailing PER | 60.0x | N/A | Based on 2025 EPS of KRW 870 (≈$0.6) |
| Forward PER | 40.0x | N/A | Based on 2026 EPS of KRW 1,416 (≈$0.9)*1 |
| PBR | 13.70x | N/A | Premium structure relative to ROE of 33.8%*1 |
4. Risk Factors & Monitoring Points
Quarterly earnings volatility may arise depending on the timing of capex execution and process transition by the primary customer. High concentration in a single core technology (HPA) creates structural vulnerability should an alternative process technology emerge. Some impact from rising raw material costs was confirmed in 1Q26, and the role of FX fluctuations as a margin-defense variable also warrants continued monitoring.
- ⚠️ Quarterly revenue volatility from delays in the primary customer's capex cycle
- ⚠️ Risk of disruption to the monopolistic supply structure should an alternative to the high-pressure annealing (HPA) process emerge
- 📌 Confirm whether DRAM 1d process development is completed (3Q26 target) and track the number of test equipment orders received
- 📌 Monitor whether quarterly operating profit margin holds above the 50% threshold — verify the path to achieving annual OPM of 53% or higher
5. Recent DART Filings
As of the analysis reference date (2026-05-18), no DART filings directly related to business operations or financial structure have been identified.
HPSP is on a path to expand order wins across logic and memory end markets, underpinned by its monopoly supply position in high-pressure annealing equipment, while sustaining an OPM of 50.5% in the Q1 2026 off-season. Whether DRAM 1d test equipment orders materialize and the pace of NAND customer additions will be the key variables driving future earnings.
