Business
SIG Group Co., Ltd. is an independent IT services group consisting of the Company and four consolidated subsidiaries. Centered on social infrastructure domains such as public sector (mutual aid associations, pensions, national health insurance), electric power, manufacturing (semiconductors and electronic component mounting), telecommunications, finance, education, healthcare, and mobility, the group provides an integrated offering spanning system development through IT infrastructure construction and Security Services. Major clients include TEPCO Systems Corporation (11.7% of net sales), NEC Corporation (10.3%), and Hitachi, Ltd. (9.7%), among other major SIers and infrastructure companies. Net sales for FY2026 (ending March 2026) reached ¥10,877 million, representing approximately 2.2x growth compared to FY2022 (ended March 2022).
Business Model
The company's basic earnings structure is a per-person-month type IT service model with labor costs and outsourcing costs as the main expenses, where an increase in headcount directly leads to sales growth. It has set an operating margin of 7% or higher as a management target, maintaining profitability through utilization rate management. The company aims to improve profitability by expanding its business domains and talent pool through M&A, and by shifting toward higher value-added services such as cloud solutions leveraging its AWS Advanced Tier Partner qualification, security assessments, and CSIRT operational support.
Company Strengths
The company has built long-term customer relationships in mission-critical domains such as public sector, electric power, manufacturing, telecommunications, and finance. It has a stable customer base, with the top three clients—TEPCO Systems, NEC, and Hitachi—accounting for approximately 31.7% of net sales, capturing ongoing demand from regulatory changes and cloud migration.
The company began building systems using AWS in 2013, and now provides an integrated service from design and construction to operations as an Advanced Tier Services Partner. It opened the Cloud Business Center (Yokohama) in 2019, and expanded into the Microsoft Azure domain from 2022. It also offers advanced specialized services such as security assessments, penetration testing, and CSIRT operational support.
Since 2022, the company has carried out multiple M&A transactions, including Y.C.O. Co., Ltd., Act Information Service Co., Ltd., U.I. Solutions Co., Ltd., and A・Creation Co., Ltd. Most recently, A・Creation, which became a subsidiary in March 2025, contributed for a full year to System Development Business sales (up 30.9% year on year) in FY2026 (ending March 2026), driving the expansion of the group's business scale.
ENVALITH's Perspective
Performance Trend
Revenue expanded 2.2x over five periods, from ¥4,916 million in FY2022 (ended March 2022) to ¥10,877 million in FY2026 (ending March 2026). The growth rate slightly decelerated from a 27.0% increase in FY2025 (ended March 2025) to a 24.0% increase in FY2026 (ending March 2026). Operating profit came to ¥751 million (up 28.7% year on year), and the operating margin continued its improving trend, reaching 6.9% (versus 6.7% in the previous period). As an external factor, sustained high-level demand for ICT investment related to DX, cloud, and generative AI supported the revenue increase. Net profit remained flat at ¥482 million (up 0.4% year on year), affected by the absence of the extraordinary gain recorded in the previous period (gain on sale of subsidiary shares of ¥54 million) and an increase in corporate taxes and other levies. For FY2027 (ending March 2027), the company forecasts revenue of ¥12,000 million (up 10.3% year on year) and operating profit of ¥800 million (up 6.5% year on year), anticipating continued growth.
Growth Strategy
As the final year of Phase 2 of the 2030 Long-Term Vision, the company is pursuing both revenue growth and improved profitability
A-Creation Co., Ltd., which became a subsidiary at the end of the previous consolidated fiscal year, contributed for a full year in FY2026 (ending March 2026), contributing to a 30.9% year-on-year increase in System Development Business sales. The company will continue to use M&A as a means of growth to expand its personnel, technology, and customer base, aiming to maximize group synergies.
Centered on the Cloud Business Center, which leverages its AWS Advanced Tier Partner qualification, the company is strengthening its proposal capabilities in the cloud, security, and generative AI fields. Against the backdrop of a market environment in which corporate ICT investment is becoming more sophisticated and diversified, particularly around DX, the company will continue to drive the acquisition of new orders.
Infrastructure & Security Services sales reached ¥3,081 million in FY2026 (ending March 2026) (up 9.6% year on year). The company will continue to strengthen its structure while capturing increased demand from the energy sector and others, enhancing its one-stop provision capability through mutual complementation with the System Development Business.
With FY2026 (ending March 2026) positioned as the final year of Phase 2, the company aims to achieve both sales growth and improved profitability, completing the foundation for the next growth phase. For FY2027 (ending March 2027), the company targets sales of ¥12,000 million, operating profit of ¥800 million, and net income of ¥505 million, establishing a sustainable profit growth model.
