Industrial transformer company Sanil Electric has improved its financial structure in recent years and laid the groundwork for succession. While stable results and a succession blueprint are in place, the fact that its current strong performance relies on the industry cycle of U.S. power infrastructure investment and the expansion of renewable energy is expected to be a variable going forward.
According to the electronic disclosure system on the 18th, Sanil Electric's liability ratio, which had been around 52%, fell to 13% last year, and most borrowing fund was repaid. Korea Credit Data's corporate credit rating also rose from BBB in 2021 to A last year.
Sanil Electric was founded in Aug. 1987 by Chair Park Dong-seok. After working at power equipment manufacturer Yuil Electric, Park started the business at age 26. Park is now the largest shareholder with 36.02% equity. With this stake, Park controls Sanil Partners and The Summit Solar One, both 100% subsidiaries of Sanil Electric.
At the time of its founding, the company focused on power transformers that raise or lower AC voltage. It built a foundation for growth by supplying transformers to Korea Electric Power Corporation and Korea National Railway, and expanded its business to overseas markets such as Japan and the Middle East.
Recently, as global big tech corporations have kicked off a full-fledged race to invest in hyperscale data centers, transformer demand has surged and Sanil Electric has drawn attention as a beneficiary. Sanil Electric's share price closed at 251,000 won on the 17th, up about 82% from early January (137,800 won).
Buoyed by market conditions, the company achieved both earnings growth and stronger financial stability. Revenue hovered between 64.3 billion and 107.7 billion won from 2020 to 2022, but reached 214.5 billion won with 46.6 billion won in operating profit in 2023. Last year, revenue expanded to 501.9 billion won and operating profit to 179.0 billion won. While total equity increased from 125.9 billion won to 585.7 billion won over the same period, total liabilities rose only from 65.4 billion won to 95.4 billion won, meaning capital expansion outpaced top-line growth.
Behind the earnings growth is a trend of expanding global investment in power infrastructure. Centered on the United States, demand for replacing aging power grids has increased, and the spread of generative artificial intelligence (AI) has led to a string of data center construction projects, boosting demand for power facility expansion. On top of that, the broader rollout of renewables such as solar and wind has ushered in a boom for the transformer market. Riding these market shifts, Sanil Electric expanded orders in overseas markets, including North America, and sustained its growth momentum.
The broad outline of the succession plan is also in place. Chair Park has two sons and one daughter. The eldest son, Park Hye-seong, has been serving at Sanil Electric, including as an inside director through 2023; the second son, Park Hye-jun, is the second-largest shareholder and a registered executive at related party Sanil Sensor; and the eldest daughter, Park Hye-su, is the second-largest shareholder of Tiwoom Co., Ltd.
Sanil Sensor was established in 2023 through a physical partitioning of Sanil Electric's sensor division, and the 100% equity stake held by Sanil Electric was sold to Chair Park Dong-seok and second son Park Hye-jun. Their current equity ratios are 68.25% and 31.75%, respectively. Tiwoom, a livestock manure biogas producer, is said to be 25.42% owned by Park Hye-su and 60.3% owned by Chair Park.
The market sees changes in the business environment as the factor that will determine Sanil Electric's corporations growth trajectory. Because more than 90% of revenue comes from exports, exchange-rate swings have a major impact. Another key is how long the boom in U.S. power grid investment, AI data center expansion, and renewable energy investment can last.
An accountant said, "Trade receivables and inventories are increasing rapidly, so if the global economy slows or client investments are delayed, the working-capital burden could grow," and added, "In particular, trade receivables have roughly quadrupled over three years and could become a key risk factor if demand cools."
