Business

Tokai Carbon, founded in 1918, is a manufacturer specializing in carbon products, operating six segments: Carbon Black, Fine Carbon, Smelting & Lining Business, Graphite Electrode Business, Industrial Furnaces and Related Products Business, and Other Businesses. Its core Carbon Black Business supplies tire manufacturers worldwide, while its Fine Carbon Business provides advanced materials such as the Solid SiC Focus Ring for semiconductor manufacturing. The company forms a global group including 31 consolidated subsidiaries, with consolidated net sales of ¥322,960 million for FY2025 (ending December 2025). Its main customers include tire manufacturers, semiconductor equipment manufacturers, aluminum smelters, and electric steelmaking furnace manufacturers, supplying carbon materials to a diverse range of industries.

Business Model

A vertically integrated model in which the company owns manufacturing facilities in each business segment, procuring and processing raw materials to manufacture and sell carbon products. The Carbon Black Business mass-produces at overseas sites in North America, Thailand, Canada, and elsewhere, supplying tire manufacturers, while the Fine Carbon Business provides high-value-added products for semiconductor applications through the domestic Tanoura Plant and overseas processing subsidiaries. The company enhances financial efficiency through centralized fund procurement at the head office via GCMS, using operating cash flow as its primary source of investment funds. For FY2025 (ending December 2025), capital expenditures were ¥36,854 million and operating cash flow was ¥55,872 million.

Company Strengths

The company operates manufacturing bases in North America (Tokai Carbon CB Ltd.), Thailand (THAI TOKAI CARBON PRODUCT COMPANY LIMITED), Canada (Cancarb Limited), and elsewhere, having built a global supply network for tire manufacturers. In September 2025, it acquired a Thai production site from Bridgestone to expand production capacity. In FY2025 (ending December 2025), sales of this business were ¥147,093 million, accounting for approximately 46% of total company sales.

The company offers specialty carbon products for semiconductor manufacturing, including the Solid SiC Focus Ring, achieving an operating margin of 13.7% in FY2025 (ending December 2025). Sales volume for the memory semiconductor market increased year on year, and following the consolidation of U.S. processing subsidiaries KBR and MWI, sales rose 3.9% year on year to ¥56,127 million. Capacity expansion investment at the domestic Tanoura Plant has also been completed, positioning the business for future growth.

In the Graphite Electrode Business, the company completed the termination of production at the Shiga Plant, consolidation at the Hofu Plant, and the sale of its German subsidiary, turning around from an operating loss of ¥3,529 million in the previous fiscal year to operating income of ¥2,389 million. The Smelting & Lining Business also improved, moving from an operating loss of ¥13,701 million in the previous fiscal year—which had included a large-scale impairment loss (¥61,239 million)—to operating income of ¥1,503 million, aided by reduced depreciation expenses. The company-wide cost of sales ratio declined by 1.7 percentage points to 75.3%.

ENVALITH's Perspective

Profit attributable to owners of parent for 1Q FY2026 (ending December 2026) was ¥1,556 million, down 47.1% year-on-year. Net sales (¥81,720 million, +1.7%) and ordinary income (¥6,181 million, -1.9%) were roughly in line with the previous year, but income taxes-deferred surged from ¥527 million to ¥1,947 million, significantly depressing net profit. Operating profit also declined to ¥6,345 million (-8.9%), and the increase in SG&A expenses (from ¥12,903 million to ¥13,971 million) putting pressure on profit margins warrants close attention.

The full-year forecast for FY2026 (ending December 2026) calls for net sales of ¥370,000 million (+14.6% year-on-year), operating profit of ¥28,000 million (+8.3%), and net profit of ¥12,000 million (-40.2%). The 1Q progress rate against the full-year forecast stood at 22.1% for net sales and 22.7% for operating profit, roughly in line with an even quarterly pace, but net profit of ¥1,556 million in 1Q represents only a 12.9% progress rate against the full-year forecast of ¥12,000 million, which is low, premising a normalization of the tax burden in the latter half. External factors such as U.S. tariff policy, the situation in the Middle East, and sluggish crude steel production in China remain as downside risks.

The annual dividend forecast for FY2026 (ending December 2026) was revised upward from the previous year's actual ¥30 to ¥40 (¥20 at the end of 2Q, ¥20 at year-end). Meanwhile, the full-year net profit forecast calls for a 40.2% year-on-year decline to ¥12,000 million, resulting in a structure where a dividend increase and declining profit coexist. Achieving the Vision 2030 targets (net sales of ¥500,000 million, EBITDA margin of 20%, ROIC of 12%) will require substantial business expansion from the current level, and it should also be considered that increased depreciation expenses from the new Thailand plant (1Q depreciation expenses of ¥7,887 million, up 21.6% year-on-year) will continue to be a factor weighing on profit for the time being.

Growth Strategy

Under the three pillars of Vision 2030, the company aims to achieve net sales of ¥500,000 million, an EBITDA margin of 20%, and ROIC of 12% by 2030

Following the acquisition of the Thailand base from Bridgestone, the entity was consolidated in Q4 2025. Production capacity is being enhanced through the operation of the new Thailand plant, but increased depreciation expenses will weigh on profits in the near term. The carbon black recycling project from end-of-life tires is also being advanced in parallel, strengthening the company's ability to respond to sustainable demand.

Sales volume of Solid SiC Focus Rings for memory semiconductors continues to increase. The company is promoting improved business efficiency through the reorganization and integration of its U.S. processed graphite subsidiary. It continues to expand production capacity and develop new applications in anticipation of a demand recovery in the SiC power semiconductor market. Net sales for Q1 of FY2026 (ending December 2026) were ¥16,401 million (+13.6% year-on-year), maintaining a growth trajectory.

The Graphite Electrode Business completed the consolidation of the Shiga plant and the sale of its German subsidiary (deconsolidated in April 2025), achieving a return to profitability with operating income of ¥251 million in Q1 of FY2026 (ending December 2026) (versus a loss of ¥725 million in the same period of the previous year). In the Smelting & Lining Business, recognition of RuC® license fee income supported earnings, with operating income improving significantly to ¥658 million (+310.5% year-on-year).

With support from the Ministry of the Environment, the company is working on the development and demonstration of functional solid carbon manufacturing technology. It is steadily advancing a carbon black recycling project using end-of-life tires and other materials, building a business foundation compatible with the circular economy. As a pillar of "Sustainable Value Creation" under Vision 2030, the company aims for a mid- to long-term transformation of its business portfolio.
