Summary

Jeryong Electric is a KOSDAQ-listed power equipment manufacturer that produces distribution transformers, switchgear, and GIS (gas-insulated switchgear), exporting mainly to the United States (founded in 1986; the current corporate entity was established via a spin-off in 2011). Per the FY2025 business report, revenue was KRW 224.017 billion (-14.7% YoY) and operating profit was KRW 67.027 billion (-31.4%), while H1 2026 (cumulative) revenue was KRW 70.323 billion, operating profit KRW 11.123 billion, and net income KRW 26.086 billion (disclosure receipt no. 20260813001320). On 2025-12-22 the company signed a distribution transformer supply contract with PSE&G in the US, and the contract value was increased to KRW 53.1 billion via a correction disclosure on 2026-01-08. The closing price on 2026-08-14 was KRW 48,700, with a market cap of KRW 781.4 billion.

Price-Change Context Note

After several years of large average annual revenue growth from 2021 to 2024 (+113.7% in 2023, +42.8% in 2024), both revenue and operating profit turned to decline in 2025; the company attributed this to intensifying competition amid supply-chain stabilization in the North American distribution transformer market, US tariffs, and higher fixed costs from preemptive investment (Digital Today, 2026-02-09). Over the same period, the US Trade Act Section 232 tariff rate on large transformers was temporarily reduced from 25% to 15% effective 2026-06-08. Over the most recent month (2026-07-16 to 2026-08-14), supply-demand flows showed net inflows from institutions and foreign investors (+81,917 / +37,187 shares) and a net outflow from retail investors (-121,240 shares), though in the most recent week (2026-08-10 to 08-14) foreign investors switched to a net outflow (-5,861 shares) (alphasquare, as of 2026-08-14).

Risk Factors

  • Customer Concentration As of 2025, the top 3 customers are believed to account for 74.6% of revenue, with the largest single customer at 37.9% (web research, C — needs cross-check against the original business report).
  • Trade & Tariffs The US Trade Act Section 232 tariff rate was temporarily reduced from 25% to 15% (effective 2026-06-08), but the expiration date is unavailable, and a re-hike could negatively affect margins.
  • Intensifying Competition Competitor HD Hyundai Electric surpassed cumulative production of 1,000 transformers at its Alabama, US plant and began a $200 million expansion (2026-08-07, Global Economic).
  • Raw Materials Copper prices rose 47.4% YoY as of 2026-08-14, exerting upward pressure on the cost ratio (TradingEconomics).
  • Fair Trade / Antitrust Following the detection of bid-rigging in a KEPCO GIS procurement tender, the company received a 6-month bidding eligibility restriction and was designated as an ineligible bidder (exact effective date unavailable, thebell, 2026-03-12).
  • Exchange Rate A shift to won strength could pressure export profitability; as of 2026-08-14, the KRW/USD rate was around 1,417–1,421.
  • Data Consistency Some web sources' figures for Q2 and H1 2026 results were inconsistent with confirmed financial data (H1 cumulative revenue of KRW 70.323 billion) and were discarded in this report.
