It has signed a binding reservation agreement with U.S.-based X-energy to supply forged primary components for 16 Xe-100 SMR units, and has decided to invest KRW 806.8 billion to build a dedicated factory in Changwon, Gyeongnam, capable of producing 20 SMR units per year, with completion targeted by June 2031. For gas turbines, the company is expanding its lineup beyond existing 380MW large-scale products to include mid-size 90MW units. The Korean government has officially set a 2035 commercialization target for the i-SMR.
| Category | Details |
|---|---|
| Position | South Korea's only SMR core component manufacturer (niche); global competitors: NuScale (leader), Westinghouse (challenger) |
| Competitive Advantage | Domestic nuclear primary equipment manufacturing capability, binding reservation agreement to supply components for 16 X-energy Xe-100 units, decision to build dedicated Changwon factory (KRW 806.8 billion investment) |
| Competitive Disadvantage | Lack of leadership in global SMR design and licensing, commercialization timeline dependent on external regulators and client decisions |
3. Valuation Analysis
Based on the current share price of KRW 129,600, the Trailing PER stands at 969.7x, approximately 5.5x the sector average of 175.7x. The Forward PER is 276.0x (consensus), contracting relative to Trailing, but still approximately 3.5x the sector average Forward PER of 78.6x, placing it firmly in overvalued territory. PBR of 10.53x against ROE of 1.7% reflects low capital efficiency. The valuation premium is interpreted as the market pre-pricing an expanding SMR order pipeline and projected future EPS improvement. The debt-to-equity ratio stands at 129.1%.
📌 Forward PER 276x (consensus) is 3.5x the sector average of 78.6x — the pace of quarterly EPS improvement will determine whether this valuation level is sustainable
| Metric | Current | Sector Average | Interpretation |
|---|---|---|---|
| Trailing PER | 969.7x | 175.7x | 5.5x sector average — overvalued relative to current earnings |
| Forward PER | 276.0x (consensus) | 78.6x | Reflects projected EPS improvement; still 3.5x sector average |
| PBR | 10.53x | — | High market value relative to book assets |
| ROE | 1.7% | — | Low capital efficiency |
| Debt-to-Equity | 129.1% | — | Leverage level warrants monitoring |
4. Risks and Monitoring Points
A Forward PER of 276.0x is significantly above the sector average Forward PER of 78.6x, and ROE of 1.7% suggests the earnings recovery is still in its early stages. Delays in global SMR commercialization timelines could shift the order pipeline, and interest rate and refinancing risks exist at a debt-to-equity ratio of 129.1%. The major industrial accident disclosure filed on 2026-04-28 warrants further review from an operational risk perspective.
- ⚠️ SMR commercialization delay risk — potential order pipeline disruption
- ⚠️ Forward PER 276x — valuation correction pressure if EPS improvement falls short of consensus estimates
- ⚠️ Interest rate and refinancing risk at a debt-to-equity ratio of 129.1%
- ⚠️ Operational and legal risks stemming from the major industrial accident disclosure on 2026-04-28
- 📌 Quarterly new order backlog (achievement rate vs. 2026 target of KRW 13.3214 trillion)
- 📌 Changes in Forward EPS consensus estimates (sustainability of Forward PER 276x level)
- 📌 Construction progress at the Changwon dedicated SMR factory and adherence to the June 2031 completion schedule
