2. Core Product Competitiveness Analysis

Sanil Electric's key products are distribution transformers and specialty transformers. Its FY2025 operating margin of 35.6% represents a superior margin structure compared to global power equipment peers Eaton (19.0%) and Schneider Electric (18.1%). As of end-Q1 2026, the order backlog stood at KRW 451.0B (≈$301.1M).*1 A disclosure in April 2026 confirmed a single contract worth KRW 50.3B (≈$33.6M) for distribution transformers destined for Bloom Energy in the United States, with a transition underway to a direct-supply structure for in-building data center installations. The company is also making new inroads into the ultra-high-voltage transformer market.

Category	Details
Position	Specialized manufacturer of distribution and specialty transformers, focused on exports to North America and Europe
Competitive Advantage	Operating margin of 35.6% — high-margin structure vs. global peers (Eaton 19.0%, Schneider 18.1%)
Competitive Disadvantage	Domestic revenue share of 2–3%, high concentration in the distribution transformer segment

3. Valuation Analysis

As of May 13, 2026, the current price is KRW 302,500 (≈$201.9) per share, with a market capitalization of KRW 9.0T (≈$6.0B). The Trailing PER of 61.9x is at 53% of the sector average of 116.5x, while the Forward PER of 45.0x is below the sector average of 59.0x.*2 PBR of 15.70x reflects the capital efficiency of ROE at 25.4%. With a debt-to-equity ratio of 16.5%, financial leverage remains low. The declining trend from Trailing PER to Forward PER implies that 2026 earnings growth is a prerequisite. Securities firms' 2026 operating profit estimates range from KRW 242.0B (≈$161.5M) to KRW 263.0B (≈$175.6M).*3

📌 Both Trailing PER of 61.9x and Forward PER of 45.0x are below the sector averages (116.5x and 59.0x, respectively)

Metric	Current	Sector Average	Interpretation
Trailing PER	61.9x	116.5x	At 53% of sector average; in undervalued territory
Forward PER	45.0x	59.0x	Further compression expected when earnings growth is factored in
PBR	15.70x	—	Premium reflecting ROE of 25.4%
Operating Margin	35.6%	—	High-margin structure maintained vs. global peers
Debt-to-Equity Ratio	16.5%	—	Stable financial structure

4. Risk and Monitoring Points

With exports accounting for over 97% of revenue, fluctuations in the USD/KRW exchange rate directly impact quarterly results. An expansion in the scope of U.S. ultra-high-voltage transformer tariff policies could also affect the distribution transformer export structure. The continuity of the Bloom Energy supply arrangement and new ultra-high-voltage transformer order wins also warrant monitoring. During the Phase 2 plant CAPA expansion, potential mismatches between the pace of backlog drawdown and shipment volumes are also key areas to watch.

• ⚠️ With exports exceeding 97% of revenue, USD/KRW exchange rate fluctuations directly impact quarterly results
• ⚠️ Potential structural changes in distribution transformer exports if the scope of U.S. tariff policies expands

• 📌 Quarterly order backlog and Book-to-Bill Ratio (whether the backlog is maintained at approximately KRW 451.0B (≈$301.1M))
• 📌 Whether quarterly operating margin is maintained at or above 35% (to confirm fixed cost absorption as CAPA expands)

5. Recent DART Disclosures

Two major disclosures have been identified since April 2026. A large-scale single supply contract and a quarterly earnings disclosure serve as the basis for understanding the current state of operations.

날짜	공시명	요약
2026-04-23	Single Sales and Supply Contract Concluded	Disclosed a single supply contract worth 503억원 (≈$33.6M) for distribution transformers supplying power to hyperscale data centers for U.S.-based Bloom Energy. The contract is structured as a direct supply arrangement to the data center.
2026-05-13	Q1 2026 Quarterly Report	Disclosed consolidated revenue of 1,503억원 (≈$100.3M) for Q1 2026 (+52.1% YoY) and operating profit of 557억원 (≈$37.2M) (+47.9%). Operating margin came in at 37.1%.

Sanil Electric is in a phase of sustained earnings growth, underpinned by its high-margin specialty transformer structure and expanding direct sales to North America and Europe. The valuation trajectory of Trailing PER 61.9x and Forward PER 45.0x warrants ongoing monitoring alongside earnings growth trends.
