| Category | Details |
|---|---|
| Market Position | #1 biosimilar company in Korea, top-tier global player (combined domestic biosimilar companies hold approximately 15–20% global market share) |
| Competitive Advantages | Profitability improvement driven by direct sales model (1Q26 operating margin 28.1%), expansion of high-margin portfolio through five new product launches, additional CMO revenue |
| Competitive Disadvantages | Growth stagnation ongoing in legacy three products (Remsima IV, Truxima, Herzuma) due to price erosion and intensifying competition |
3. Valuation Analysis
Based on the current price of 190,500 KRW (≈$127.2) as of 2026-05-12, the Trailing PER of 42.8x exceeds the sector average of 29.4x by 13.4 turns. Meanwhile, the Forward PER of 29.0x based on the 2026 consensus EPS of 6,116~6,780 KRW (≈$4.1~$4.5)*1 is broadly in line with the sector average Forward PER of 28.7x. This gap reflects net profit growth from the 2025 base EPS of 4,458 KRW (≈$3.0) to the projected 2026 EPS of 6,116~6,780 KRW (≈$4.1~$4.5)*1. PBR stands at 2.42x and ROE at 5.9% (2025A), with ROE lagging relative to PBR; however, operating margin improved 10.4pp year-over-year to 28.1% in 1Q26 (vs. 17.7% in the prior-year period), signaling a structural shift in profitability. Intangible assets (including goodwill) account for a significant portion of total assets, warranting separate consideration when interpreting the PBR.
📌 Trailing PER signals overvaluation, but Forward PER is converging to the sector average — the key variable is whether 2026 EPS growth materializes
| Metric | Current | Sector Average | Interpretation |
|---|---|---|---|
| Trailing PER | 42.8x | 29.4x | Overvalued by 13.4 turns vs. sector average |
| Forward PER | 29.0x | 28.7x | Converging to sector average |
| PBR | 2.42x | — | Intangible asset (goodwill) weighting requires separate review |
| ROE | 5.9% (2025A) | — | Key question is whether the improving operating margin trend is reflected |
| Operating Margin | 28.1% (1Q26) | — | Improved 10.4pp vs. prior-year period (17.7%) |
4. Risk Factors and Monitoring Points
Continued price cuts and intensifying competition for legacy products (Remsima IV, Truxima, Herzuma) are structural headwinds compressing the existing revenue base. Delays in normalizing utilization rates at the Branchburg, U.S. facility represent a near-term cost headwind, while changes in U.S. CMS biosimilar adoption policy and new competitor approvals could also weigh on market share.
- ⚠️ Risk of revenue base erosion from price cuts and heightened competition for legacy products (Remsima IV, Truxima, Herzuma)
- ⚠️ Near-term cost rate increase if utilization normalization at the Branchburg, U.S. facility is delayed
- ⚠️ U.S. CMS policy changes and new biosimilar market entries by global competitors
- 📌 Quarterly trend in new biosimilar revenue mix (50.8% as of 1Q26; tracking whether it expands to 60%+)
- 📌 Branchburg, U.S. facility utilization rate and gross margin trajectory (1Q26: 59.9% → directional trend from 2Q26 onward)*3
