Business

Taiyo Holdings Co., Ltd. is composed of two core businesses: Electronics, centered on the development, manufacture, and sale of chemical materials for electronic components—principally Solder Resist (SR) for printed circuit boards (PCBs)—and Healthcare & Pharmaceuticals, which manufactures, sells, and undertakes contract manufacturing of Long-listed Products. The Electronics business operates globally through 25 consolidated subsidiaries in Japan and overseas, with overseas sales accounting for over 90% of the total. Its main customers are dedicated PCB manufacturers and in-house PCB divisions of electronics manufacturers, supplying materials for a wide range of end products including smartphones, AI servers, and automotive equipment. In the Healthcare & Pharmaceuticals business, Taiyo Pharma Co., Ltd. sells 19 Long-listed Products, while Taiyo Pharmatech Co., Ltd. handles contract manufacturing. Consolidated net sales for FY2026 (ending March 2026) totaled ¥137,851 million.

Business Model

In Electronics, the company sells high-value-added chemical materials centered on Solder Resist (SR) and Dry Film (DF) products for rigid substrates and semiconductor package substrates. As many product sales prices are denominated in foreign currency, the company maintains cost competitiveness by promoting local production and local procurement under its "local production, local sales" policy. In Healthcare & Pharmaceuticals, revenue is generated through two pillars: manufacture and sale of Long-listed Products (Manufacture & Sale of Prescription Drugs) and Contract Manufacturing of Prescription Drugs. In FY2026 (ending March 2026), the Electronics segment profit margin remains at a high level of approximately 30.6%.

Company Strengths

The company's annual securities report explicitly states that it holds a world-class share in the SR market and that its overseas sales ratio exceeds 90%. It operates global manufacturing and sales bases, with consolidated subsidiaries in South Korea, Taiwan, China, the United States, Vietnam, and other locations. Through its long-established customer base and accumulated technology, it has built a market position that competitors find difficult to replicate in the short term.

The company opened its technology development center 'InnoValley' in 2024, and R&D expenses reached ¥7,637 million in FY2026 (ending March 2026) (up ¥425 million year on year). DF-type Solder Resist (SR) meets requirements such as thickness precision and opening precision for PKG substrates, and is widely adopted in PKG substrates for AI-related memory, CPUs, and GPUs. New products such as inkjet-compatible SR, photosensitive coverlay, and interlayer insulating materials have also reached the mass production and adoption stage.

Taiyo Pharma Tech Co., Ltd. is a dedicated contract manufacturing company that took over the Takatsuki Plant from Daiichi Sankyo Propharma, and contract manufacturing from new client companies gained momentum in full in FY2026 (ending March 2026). Sales in Healthcare & Pharmaceuticals grew sharply to ¥36,490 million (up 15.6% year on year), with segment profit surging to ¥5,063 million (up 147.1% year on year). The two-business structure alongside Electronics contributes to risk diversification.

ENVALITH's Perspective

In FY2026 (ending March 2026), Electronics segment sales reached ¥95,285 million (up 16.6% year on year), with segment profit of ¥29,177 million (up 36.0% year on year), representing substantial growth. As an external factor, demand for Dry Film (DF) products for semiconductor memory expanded consistently throughout the period, driven by the spread of AI. The consolidated operating profit margin improved by 5.1 percentage points to 23.6% from 18.5% in the previous period, clearly reflecting the effect of fixed cost leverage.

In FY2026 (ending March 2026), the Healthcare & Pharmaceuticals segment achieved a substantial profit increase (segment profit up 147.1% year on year), but the forecast for FY2027 (ending March 2027) projects segment profit of ¥4,000 million (down 21.0% year on year), a decline. The main causes are rising raw material prices and increases in cost of sales and selling, general and administrative expenses. The decline in sales volume of Long-listed Products (Manufacture & Sale of Prescription Drugs) due to the introduction of the selected medical care system continues to be a persistent headwind, making it necessary to monitor the sustainability of profitability.

Regarding the planned commencement of a tender offer by KJ005 Co., Ltd. as of March 31, 2026, the Board of Directors has expressed its support (leaving the decision of whether to tender to the judgment of individual shareholders). In connection with this, the company has resolved not to pay a year-end dividend for FY2026 (ending March 2026), and no dividend is planned for FY2027 (ending March 2027) either. The FY2027 (ending March 2027) earnings forecast may incur additional expenses related to the tender offer, presenting a risk that actual results could diverge from the forecast figures. The progress of the tender offer and any changes to the management structure going forward will be the most closely watched points.

Growth Strategy

Long-term strategy centered on continued growth in the Electronics business, restructuring of the Healthcare business, and creation of new businesses

Continuously capture expanding demand for Dry Film (DF) products used in semiconductor memory, driven by the spread of AI. In FY2027 (ending March 2027), sales volume is expected to increase further, led by memory-related products, with Electronics segment sales forecast at ¥102,200 million (up 7.3% year on year) and segment profit forecast at ¥31,300 million (up 7.3% year on year).

Promote the full-scale ramp-up of contract manufacturing for new outsourcing clients at Taiyo Pharma Tech, along with increased order volumes from existing customers. Revenue is expected to increase in FY2027 (ending March 2027), but profit is expected to decrease due to higher cost of sales and SG&A expenses. Continued expansion of sales to Daiichi Sankyo will be key to stabilizing earnings.

Expenditures for acquisition of property, plant and equipment in FY2026 (ending March 2026) increased to ¥7,335 million (from ¥6,312 million in the previous fiscal year). Construction in progress increased substantially, from ¥3,477 million at the end of the previous fiscal year to ¥6,410 million at the end of the current fiscal year, reflecting ongoing investment to expand production capacity going forward. The increase in tangible and intangible fixed assets in the Electronics segment amounted to ¥5,993 million.

With respect to the planned commencement of a tender offer by KJ005 Co., Ltd. effective March 31, 2026, the Board of Directors has expressed its support. The tender offer price has been determined on the premise that no dividend will be paid with a record date of March 31, 2026, and the company plans not to pay a year-end dividend for FY2026 (ending March 2026) or any dividend for FY2027 (ending March 2027). Future changes in management structure and capital policy will be closely watched.
