Samwha Electric

Samwha Electric is an aluminum electrolytic capacitor specialist founded in 1973, operating as an affiliate within the Samwha Capacitor Group alongside Samwha Capacitor, Samwha Electronics, Samwha Techcom, and Korea JCC.

Its core products include aluminum electrolytic capacitors, conductive polymer hybrid capacitors, electric double-layer capacitors (EDLC, Green-Cap), and S-Cap products for SSDs, supplied as single cells or modules.

The company serves more than 300 customers worldwide and has stated a goal of reaching the global top three in the electrolytic capacitor segment through continued technology and quality improvements.

Its flagship Hybrid-Cap (YC/YH series) was the first domestically developed product to use both solid and liquid electrolytes simultaneously, addressing voltage-limit and short-circuit issues while doubling product lifespan.

The EDLC (Green-Cap) line is a supercapacitor offering rapid charge-discharge characteristics and near-permanent cycle life, produced as single cells or modules. End markets span smart appliances, eco-friendly energy, 5G communications, electric vehicles, and AI/ICT applications.

Beyond its headquarters in Cheongju, the company operates an overseas subsidiary in Tianjin, China, along with sales entities in the United States, Europe, Hong Kong, and Poland.

The global aluminum electrolytic capacitor market is led by Japan's Nichicon and Nippon Chemi-Con along with Taiwanese vendors, making Samwha Electric a comparatively smaller player against these larger incumbents.

Consolidated revenue in 2025 came in at KRW 230.1 billion, down 1.3% from KRW 233.1 billion in 2024, while operating profit plunged 51.4% from KRW 24.8 billion to KRW 12.0 billion, and net profit attributable to owners fell 51.9% from KRW 19.6 billion to KRW 9.4 billion.

As a result, the operating margin roughly halved, from 10.6% in 2024 to 5.2% in 2025. Looking across the four disclosed years, operating margin bottomed at 3.9% in 2023 after 5.7% in 2022, rebounded to 10.6% in 2024, and then reverted to 5.2% in 2025, illustrating a pronounced cyclical pattern.

Quarterly results show similar volatility. In the second quarter of 2025, revenue of KRW 59.2 billion and operating profit of only KRW 0.8 billion coexisted with a comparatively large owners' net profit of KRW 4.8 billion, suggesting a quarter with meaningful non-operating contributions.

Subsequent quarters—2025Q3 (revenue KRW 54.0 billion, operating profit KRW 3.1 billion, net profit KRW 1.8 billion), 2025Q4 (KRW 55.1 billion, KRW 2.4 billion, KRW 1.8 billion) and 2026Q1 (KRW 57.4 billion, KRW 3.4 billion, KRW 1.4 billion)—showed a narrower gap between operating and net profit, but 2026Q2 saw both revenue (down to KRW 53.6 billion) and operating profit (down to KRW 1.4 billion) contract again, interrupting the improvement trend.

Over the latest four quarters (2025Q3-2026Q2), combined revenue reached KRW 220.2 billion and operating profit KRW 10.3 billion, implying an operating margin of roughly 4.7%, below even the full-year 2025 level.

Owners' net profit over this same four-quarter window totaled KRW 6.2 billion, underscoring the need to continue monitoring the quality and one-off nature of quarterly earnings.

Industry commentary suggests the global aluminum electrolytic capacitor market entered an unusual price up-cycle in 2026 as AI data-center demand collided with rising raw-material costs.

The build-out of AI server capacity has reportedly increased the number of power supplies per rack and the share of high-ripple, long-life aluminum electrolytic capacitors used in those designs.

Japan's Nichicon and Nippon Chemi-Con have notified customers of across-the-board price increases, with initial plans for 9-12% adjustments said to have shifted toward 10-15% for series used in AI server and power-system applications.

Reports also indicate Taiwanese aluminum capacitor vendors joined price increases during mid-2026 in response to higher input costs and tighter supply-demand conditions. Chemical material costs are said to have risen roughly 30-40% and metal costs around 10%, giving suppliers rationale to pass through price increases.

Capacity utilization at major aluminum electrolytic capacitor lines in Japan, China and Taiwan has reportedly remained high since early 2026.

However, the benefits of this up-cycle appear concentrated among larger suppliers of high-end products for AI servers, and there is no company-specific disclosure or news confirming the extent to which a smaller specialist such as Samwha Electric is participating in this trend.

Domestically, expanding imports of low-cost products from Southeast Asia and China have been cited as a competitive pressure, placing the company in an environment where rising input costs and low-cost competition are occurring simultaneously.

The company has stated that while intensifying global competition and rising imports of low-cost products from Southeast Asia and China weighed on revenue, it is strengthening competitiveness in the 5G communications and automotive segments through a quality- and technology-focused strategy.

Samwha Electric reportedly holds domestic and international patents covering EDLC electrodes and solid electrolytic capacitor manufacturing methods, which it has leveraged to build technological competitiveness in the renewable energy market.

However, no specific company-level order wins, capacity expansion plans, or revenue guidance for Samwha Electric itself were identified through available sources.

By contrast, affiliate Samwha Capacitor has drawn market attention in connection with rising MLCC demand tied to AI data centers, and it remains to be seen how much of that group-level tailwind extends to Samwha Electric's electrolytic capacitor business.

Should the broader up-cycle in aluminum electrolytic capacitor pricing persist, the extent to which cost increases can be passed through to selling prices is likely to be a key variable for future margins.

Given that operating margin has fluctuated around the 5% level over the past four quarters, how the balance between input costs and selling prices evolves in coming quarters will be worth watching.

The operating status and any additional investment at the company's overseas production base in Tianjin also warrant confirmation through future disclosures.
