Business

CK SanEtsu is a pure holding company headquartered in Takaoka City, Toyama Prefecture, overseeing 14 group companies including SanEtsu Metal, Nippon Shindo, Mitani Shindo, and CK Metal. In its core Copper Rolling & Extrusion business, the company manufactures Brass Rods, Wire, and Tubes, supplying them widely as materials for automobiles, home appliances, and Faucet Fittings (Precision Parts), among others. The Precision Parts business handles forged and machined products such as Camera Mounts and Synchro Rings, while the Piping & Plating business offers PVC-free fittings and environmentally friendly hot-dip galvanizing. The company holds numerous patents for environmentally friendly alloys and plating processes that do not use lead, cadmium, or similar substances, and boasts the top share in the domestic copper rolling & extrusion industry. In April 2025, the company made Mitani Shindo a consolidated subsidiary, expanding its scale to sales volume of 100,389 tons and net sales of ¥149,438 million.

Business Model

The company procures copper and zinc, the main raw materials, from the market and processes them into Brass Rods, Wire, Tubes, etc., which are sold to the automotive, home appliance, and construction industries. Since product prices are linked to the copper price benchmark, the company hedges price volatility risk through derivative transactions to stabilize results at the recurring profit level. While supplementing profit margins through the high-value-added Precision Parts and Piping & Plating segments, the company maintains competitiveness through scale expansion via M&A of peer companies and production synergies.

Company Strengths

Through the three-company structure of San-Etsu Metals, Nippon Chuzo, and Mitani Shindo, sales volume in the copper rolling & extrusion business for FY2026 (ending March 2026) reached 100,389 tons (up 11.7% year on year), with sales of ¥131,442 million achieved. The company can leverage scale merits through joint raw material procurement and consolidation of production sites, and possesses negotiating power backed by its top industry market share.

The company has commercialized environmentally friendly alloys that do not use environmentally hazardous substances such as lead and cadmium, and has obtained numerous patents. In the Piping & Plating business as well, it holds patented technologies such as PVC-free fittings and the environmentally friendly hot-dip galvanizing process "CKe Mekki Super," which is registered with the Ministry of Land, Infrastructure, Transport and Tourism's NETIS. The company also has products that have won the Good Design Award, achieving differentiation in demand driven by regulatory compliance.

The company has continuously executed M&A of competitors, including making Nippon Chuzo a consolidated subsidiary in 2015 and Mitani Shindo a consolidated subsidiary in April 2025 (final voting rights ratio of 94.06%). Since transitioning to a holding company structure in 2011, it has accumulated acquisitions such as CK Metals, Okino Kogyo, and the Hitachi Alloy business, achieving a track record of expanding sales from ¥115,343 million (FY2022, ended March 2022) to ¥149,438 million (FY2026, ending March 2026).

ENVALITH's Perspective

In FY2026 (ending March 2026), the copper benchmark price rose to ¥2.19 million per ton (an external factor), and as a result operating profit performed well at ¥14,161 million (up 38.0% year on year). However, derivative losses of ¥8,936 million and derivative valuation losses of ¥251 million arose, causing ordinary profit to fall to ¥5,636 million (down 32.8% year on year). The structure in which derivatives, used as a hedge against price volatility risk, significantly depress ordinary profit and net profit during phases of sharp price surges is a factor that reduces the visibility of earnings for investors and warrants close attention.

Mitani Shindo, consolidated in April 2025, contributed to the Copper Rolling & Extrusion segment's revenue of ¥131,442 million (up 23.5% year on year) and segment profit of ¥11,177 million (up 57.7% year on year) from its first year, and the integration effect got off to a numerically favorable start. Going forward, the focus of evaluation will be whether mutual utilization of production technology and know-how, consolidation of production sites through OEM production, and cost reduction through joint purchasing actually materialize as improved profit margins. The voting rights ratio has been raised to 94.06%, and unification of group management is progressing steadily.

The earnings forecast for FY2027 (ending March 2027) is revenue of ¥180,000 million (up 20.5% year on year), operating profit of ¥10,000 million (down 29.4% year on year), and ordinary profit of ¥10,000 million (up 77.4% year on year). Operating profit is expected to decline on the assumption that the price gains recorded in the current period will not recur in the next period, while ordinary profit is expected to increase on the assumption that the derivative losses recorded in the current period will not recur in the next period. If the assumed prices of ¥2,110 thousand/ton for electrolytic copper and ¥586 thousand/ton for electrolytic zinc deviate from actual market prices, there is a risk that the earnings forecast could fluctuate significantly. The introduction of a progressive dividend policy (to be adopted from FY2027 (ending March 2027), with an annual dividend of ¥100 planned) can be evaluated as a clarification of the company's stance on shareholder returns.

Growth Strategy

Leading industry consolidation through M&A while breaking through the mature market via production technology synergies and expansion of high-value-added products

In April 2025, Mitani Copper Rolling & Extrusion was made a consolidated subsidiary (acquisition cost of ¥2,733 million), and through subsequent additional acquisitions, the voting rights ratio was raised to 94.06%. Sales volume in the Copper Rolling & Extrusion business expanded to 100,389 tons (up 11.7% year on year), and contributions to sales and profit were confirmed from the first year of integration.

State-of-the-art horizontal continuous casting equipment will be introduced at the Tonami Plant of San-Etsu Metals Co., Ltd., aiming to improve productivity and realize a night-shift-free operation. This initiative addresses labor shortages while reducing manufacturing costs, and is expected to contribute to strengthening medium- to long-term competitiveness.

Within the Precision Parts segment, San-Etsu Metals Co., Ltd. is focusing on increasing production of Backing Plates for semiconductor manufacturing equipment. Precision Parts segment profit for FY2026 (ending March 2026) showed strong growth at ¥906 million (up 45.2% year on year), with the expansion of high-value-added products contributing to improved profitability.

CK Metals Co., Ltd. is focusing on developing new pipe fitting products and new hot-dip galvanizing technologies. The Piping & Plating segment struggled in FY2026 (ending March 2026), with net sales of ¥11,985 million (down 8.2% year on year) and segment profit of ¥1,872 million (down 15.2%), making profitability recovery through new products and new technologies a key challenge.

Starting from FY2027 (ending March 2027), the company has adopted a "progressive dividend" policy of maintaining or increasing dividends without reduction. The annual dividend for FY2026 (ending March 2026) was ¥90 (payout ratio of 20.8%), and ¥100 is planned for FY2027 (ending March 2027). The company aims to enhance medium- to long-term shareholder value through continued stable dividends that are less susceptible to short-term earnings fluctuations.
