Business

S&J Corporation is a cybersecurity-focused company founded in 2008. Targeting large and mid-sized enterprises as its main customers, it operates on two pillars: the Consulting Service, which provides security advisory, incident response, vulnerability assessment, and other offerings; and the SOC Service, a 24-hour, 365-day operation utilizing its in-house developed SIEM "SOC Engine," the cloud-based EDR "KeepEye®," and AD monitoring, among others. The company also leverages a sales agency network including SIer partners to offer domestically produced, low-cost products and services to small and medium-sized enterprises. It listed on the Tokyo Stock Exchange Growth Market in December 2023.

Business Model

The majority of revenue is composed of subscription-based recurring revenue built primarily on annual contracts. As of the end of FY2026 (ending March 2026), ARR stood at ¥2,134,256 thousand (up 18.4% year-on-year), with contract liabilities exceeding ¥599 million. While maintaining a high retention rate through continued service to existing customers, the company captures spot projects such as incident response through its Consulting Service, and builds a circular model that guides those customers toward the SOC Service. The company is also expanding its sales channels through agencies such as Macnica and Softcreate.

Company Strengths

Through a stock-type revenue model based primarily on annual contracts, ARR at the end of FY2026 (ending March 2026) reached ¥2,134,256 thousand (up 18.4% year on year). Contract liability balances also increased by ¥43,473 thousand year on year, and total order backlog stood at ¥1,695,415 thousand (up 47.3% year on year), providing high visibility into future revenue. A high customer retention rate forms a stable revenue base.

The company owns multiple in-house developed products, including SOC Engine (proprietary SIEM), KeepEye® (cloud-based EDR), and S&J AD Agent® (AD monitoring agent). It has established a mechanism to feed back insights accumulated through consulting for large enterprises into its products and services, and possesses the technical flexibility to also support the operation of third-party SIEM and EDR products.

The operating margin for FY2026 (ending March 2026) was 23.8% (improved from 21.6% in the previous fiscal year). The company has no borrowings from financial institutions, and cash and cash equivalents stood at ¥2,249,429 thousand. With an equity ratio of 71.2%, the company maintains a solid financial base, enabling autonomous growth investment funded by retained earnings.

ENVALITH's Perspective

In FY2026 (ending March 2026), the company achieved revenue growth of 20.1% and operating income growth of 32.2%, but the company's forecast for FY2027 (ending March 2027) indicates a slowdown in profit growth, with revenue expected to grow 17.4%, operating income 11.5%, and net income only 0.1%. The forecast, in which profit growth significantly lags behind revenue growth, suggests an increase in upfront costs such as personnel hiring and technology investment, and it is necessary to closely monitor the company's track record in cost control.

As an external factor, against the backdrop of increasingly severe cyberattacks on major corporations and frequent ransomware incidents, IT investment in information security continues to trend upward regardless of company size or industry, and the demand environment remains favorable. On the other hand, the growth potential of this market is encouraging entry by major IT vendors and emerging security companies, raising the risk of intensifying competition. The recruitment and development of specialized talent is a rate-limiting factor for business expansion, and it appears that the pace of increase in selling, general and administrative expenses is reflected in the FY2027 (ending March 2027) forecast.

In FY2026 (ending March 2026), the company implemented its first year-end dividend of ¥15 per share (payout ratio of 20.6%), and plans to increase the dividend to ¥17 per share (forecast payout ratio of 23.3%) in FY2027 (ending March 2027). In addition, the company invested ¥354 million in share buybacks during the fiscal year, making clear a shift in management's stance toward shareholder returns. However, the disposal of treasury shares (proceeds of ¥78 million) was also carried out simultaneously, and it is necessary to continue monitoring the overall picture of capital policy, including its relationship to stock option exercises and similar matters.

Growth Strategy

The company aims to accelerate growth through a three-pronged approach combining ARR accumulation, expansion of new services, and strengthening of sales capabilities.

The company continues to promote new customer acquisition utilizing in-house developed products such as KeepEye®. SOC Service revenue in FY2026 (ending March 2026) reached ¥1,767 million (up 22.6% year on year), steadily expanding as a core service, and new order acquisition will remain the primary growth driver in FY2027 (ending March 2027) as well.

The company has secured engagements centered on suspicious email training support and security incident response. Consulting Service revenue in FY2026 (ending March 2026) was ¥565 million (up 13.0% year on year). It also serves as a gateway to SOC Service, positioned as an entry point for deepening customer relationships.

The company continues to promote detailed understanding of customer needs, technical improvement, corporate brand strengthening, and talent recruitment. The anticipated increase in SG&A expenses in FY2027 (ending March 2027) is seen as reflecting upfront investment, with priority given to building a mid- to long-term foundation for growth.

The company paid its first dividend in FY2026 (ending March 2026) (year-end dividend of ¥15), and plans to increase the dividend to ¥17 in FY2027 (ending March 2027) (payout ratio of 23.3%). It is also actively conducting share buybacks, pursuing a capital policy that balances growth investment with shareholder returns.
