Bosung Power Technology

Founded in 1970 and listed on KOSDAQ in 1994, Bosung Powertec is a power equipment specialist with production facilities in Chungju, North Chungcheong Province, and Naju, South Jeolla Province.

The business is split into two divisions: the steel structure division, which produces transmission towers, tubular support structures, and steel structures for power plants and substations, and the heavy electrical equipment division, which makes gas switchgear, pole-mounted transformers, and related switching and protection devices.

Transmission towers, the core product, have typically made up about 40-50% of annual revenue, but that share expanded to roughly 70% in 2025 due to the Donghaean-Singapyeong HVDC project.

Major customers include KEPCO, its generation subsidiaries, and domestic and overseas EPC contractors, with the KEPCO supply relationship forming the backbone of the company's growth history.

In exchange sector classification, the company sits in the KOSDAQ metals category (machinery under the WI26 standard), competing domestically with similarly sized power equipment names such as Jeryong Electric and Jeryong Industry.

The company has also reportedly pursued expansion into new energy areas such as solar and into overseas markets including the Philippines and Myanmar.

Annual revenue, which was in the low billions of won in its early years, grew past the 100 billion won mark in the 2010s before settling into a roughly 50-80 billion won range over the past three to four years, then jumped sharply again in 2025.

The largest shareholder group is led by Lim Jae-hwang and two related parties, with an ownership change recorded in December 2025.

Consolidated revenue in 2025 reached 147.49 billion won, up roughly 91% from 77.06 billion won a year earlier, while operating profit surged 456% to 26.81 billion won from 4.82 billion won.

Owner-attributable net profit also rose sharply to 20.31 billion won from 5.95 billion won, and the operating margin jumped from 6.3% to 18.2%.

This follows a steady profitability recovery from an operating loss in 2022 (-4.49 billion won, margin -8.3%) through 2023 (operating profit of 3.35 billion won, margin 4.3%) and 2024 (4.82 billion won, 6.3%), before a single large contract pushed results to another level in 2025.

On a quarterly basis, revenue and operating profit peaked in the second quarter of 2025 at 55.83 billion won and 13.66 billion won (owner net profit of 11.01 billion won), then gradually moderated to 36.81 billion won and 6.17 billion won in the third quarter and 37.39 billion won and 5.42 billion won in the fourth quarter.

The first quarter of 2026 saw a modest rebound to 40.86 billion won in revenue and 5.95 billion won in operating profit, but the second quarter of 2026 saw revenue drop sharply to 24.39 billion won with operating profit falling to 4.73 billion won.

Notably, the operating margin in that second quarter still held around the high-teens percentage, suggesting profitability itself was relatively well defended even as revenue scale contracted.

On cash flow, operating cash flow in 2025 came in at 43.70 billion won, a marked improvement from negative 10.00 billion won in 2024, while the debt ratio at the end of 2025 stood at 20.9%, somewhat higher than the 5.8-13.9% range seen from 2022 to 2024 but still at a low level overall.

The power equipment industry's key driver is the surge in electricity demand from AI data centers and semiconductor clusters, alongside expanding investment in high-voltage direct current (HVDC) transmission needed to move power generated in one region to the capital area and industrial complexes.

Bosung Powertec has already built up large-scale supply experience on domestic 500kV HVDC overhead transmission lines and has used that track record to participate in follow-on tenders that include load-testing requirements for 500kV HVDC six-bundle tubular towers.

The domestic tower and tubular tower market is heavily dependent on KEPCO's order schedule, a structure in which individual companies' results can swing significantly depending on the timing and scale of contract awards.

The competitive landscape includes similarly sized power equipment small-caps such as Jeryong Electric, Jeryong Industry, and GNC Energy, many of which are known to maintain relatively stable double-digit operating margins.

Demand for replacing aging grid infrastructure and expanding transmission networks to connect renewable energy are also cited as medium-to-long-term growth drivers for the sector as a whole.

However, because large order announcements are a primary catalyst for both share price and earnings momentum in this market, a gap in new orders at any given point can widen the disconnect between industry optimism and actual revenue.

Compared with large global EPC players, Bosung Powertec operates at a different scale and scope, positioning itself more as a component and structure supplier than a direct competitor.

The company's 2025 business report stated that last year's operating results were heavily dependent on the single Donghaean-Singapyeong HVDC transmission line contract, which ended on February 28, 2026.

Following that, the company attempted to diversify its order book by signing a 17.3 billion won supply contract with Sean ENC in October 2025 for transmission tower materials for the Eumseong natural gas power plant project.

In 2026, KEPCO issued an additional tender for 500kV HVDC tubular towers on the Donghaean-Dongseoul route, an estimated 9.28 billion won bid that was re-advertised as of last May and includes load-testing requirements for 500kV HVDC six-bundle tubular towers, conditions viewed as favorable for a company with existing reference experience.

The next regular disclosure, the third-quarter 2026 report, must be filed by November 16, 2026 under the Capital Markets Act, at which point it should become clear whether the second-quarter revenue gap persists into the third quarter or whether new orders have been reflected.

The company is also known to be continuing efforts to expand cooperation networks with overseas EPC contractors and diversify into new energy business areas beyond KEPCO and its generation subsidiaries.

Still, the fact that no follow-on mega order on the scale of the Donghaean-Singapyeong contract had been disclosed as of the business report filing remains a key variable for future earnings direction.
