Business

Ryoyu Systems Co., Ltd. was founded in 1968 and is listed on the Standard Market of the Tokyo Stock Exchange. As an equity-method affiliate of Mitsubishi Heavy Industries, Ltd., it provides the group with design, development, operation, and maintenance of information and communication systems, analysis and simulation of industrial products, information processing services, and sales of system-related equipment. The company operates as a group including three consolidated subsidiaries, and net sales for FY2026 (ending March 2026) totaled ¥43,229 million. Sales to Mitsubishi Heavy Industries accounted for 61.1% of the total, reflecting deep expertise in IT services for the manufacturing industry.

Business Model

Based on long-term business relationships with the Mitsubishi Heavy Industries Group, its primary customer, the company secures stable revenue by continuously providing diverse services including system development, maintenance, operation, and analysis/design. Sales to Mitsubishi Heavy Industries account for 61.1% of net sales, under an order-based business model that has built up an order backlog of ¥9,553 million. Working capital and capital expenditures are funded internally, and with interest-bearing debt limited to only ¥6 million in lease obligations, the company maintains a high level of financial soundness.

Company Strengths

As an equity-method affiliate of Mitsubishi Heavy Industries, Ltd., sales to the company reached ¥26,432 million (61.1% of the total). This represents an increase in both amount and ratio from ¥22,563 million (52.8%) in the previous fiscal year, indicating steady progress in deepening customer relationships. Since its founding in 1968, the track record and trust cultivated through IT services for the manufacturing industry form a barrier to entry.

The operating margin for FY2026 (ending March 2026) stood at 12.7%, maintaining a high level for an information services company. This represents a 5.0 percentage point improvement over four years from the 7.7% operating margin recorded in FY2022, driven by company-wide initiatives such as thorough project management, optimized staff allocation, and quality improvement, which have contributed to the enhanced profit margin. Interest-bearing debt consists solely of lease obligations of ¥6 million, underscoring a solid financial base.

The company has accumulated advanced technical computation and engineering service capabilities in fluid analysis, structural analysis, electromagnetic field analysis, and other areas since the establishment of Ryoyu System Giken Co., Ltd. (菱友システム技術) in 1984. The analysis and design domain, deeply embedded in the product development processes of manufacturing companies, is a specialized field difficult for competitors to imitate, and is leveraged both to deepen relationships with existing customers and to expand into new analysis fields.

ENVALITH's Perspective

In FY2026 (ending March 2026), the operating margin continued to improve to 12.7% (11.3% in the previous fiscal year), but the consolidated earnings forecast for FY2027 (ending March 2027) calls for net sales of ¥45,000 million (+4.1%) against profit attributable to owners of parent of ¥3,600 million (-7.9%), indicating a decline in earnings. Operating profit is also forecast to decrease slightly to ¥5,450 million (-0.7%), and rising personnel expenses and upfront costs for investment in new business areas could weigh on profitability. Uncertainty in the external market environment also remains.

The company's business structure, characterized by a single segment and concentration on key customers, inherently carries the risk that fluctuations in the performance of the Mitsubishi Heavy Industries group or changes in its investment policy will directly affect the company's results. While the medium-term management plan also emphasizes new customer development, non-consolidated net sales for FY2026 (ending March 2026) were ¥32,968 million (-1.0% year on year), falling short of the growth in consolidated net sales, suggesting a structure that relies on sales expansion through subsidiaries and group companies. Continued attention is needed on the progress of customer diversification.

In terms of the market environment, the expansion of demand driven by the shift to cloud computing, the commercialization of generative AI, and the strengthening of cybersecurity is a factor continuously boosting IT investment, and the company's business environment is favorable. On the other hand, labor shortages across the information services industry as a whole are severe, and the company has positioned strengthening recruitment, revising its education system, and promoting the use of external resources as key measures in its medium-term plan. Since delays in securing and developing human resources directly lead to lost order opportunities, the effectiveness of human capital investment is seen as the largest internal variable determining medium- to long-term growth.

Growth Strategy

Under "Ryoyu that runs alongside its customers," the company is pursuing expansion into new business areas, strengthening human capital, and optimizing the group.

Actively promoting sales activities and business development in new areas such as generative AI and information security. R&D expenses increased to ¥145 million (from ¥130 million in the previous period), continuing upfront investment in product development and other areas. The policy is to continue actively investing in the expansion of new areas in FY2026 as well.

Promoting thorough project management for large-scale system development, expanding orders in adjacent areas, and deepening relationships with existing customers in areas such as analysis & design and AI. Aiming to expand involvement from customers' planning and design stages to build deeper relationships of trust. In FY2026 (ending March 2026), an expansionary trend was maintained, centered on system development and analysis & design-related businesses.

Continuing to promote human capital enhancement measures, including strengthening recruitment, revising education systems to strengthen technical capabilities, enriching training programs for developing management personnel, promoting the use of external resources, and flexible reassignment of personnel. Employee salaries and allowances increased to ¥1,682 million (from ¥1,487 million in the previous period), indicating progress in human capital investment.

Working to strengthen company-wide functions such as quality improvement and to promote cybersecurity measures in the company's operations. Improving productivity through optimized staff allocation is also positioned as an ongoing issue.

Promoting business expansion through strengthened collaboration with group companies and business partners. Against consolidated net sales of ¥43,229 million for FY2026 (ending March 2026), non-consolidated net sales were ¥32,968 million (down 1.0%), a structure in which sales expansion through group companies is supporting consolidated results. Non-controlling interests increased to ¥1,743 million.
