Business

Sun Corporation is a Tokyo Stock Exchange Standard Market-listed company founded in 1971. It operates four segments: digital intelligence solutions for criminal investigation agencies (Global Data Intelligence Business), gaming machine parts and game content (Entertainment-related Business), M2M/IoT communication equipment and B2B business support systems (IT-related Business), and digital health including sleep tech (Wellness Business). Its main customers span a wide range including law enforcement agencies, pachinko halls, telecom carriers, and industrial users, forming a group comprising 6 domestic and overseas subsidiaries and 15 equity-method affiliates. Its equity investment in Cellebrite DI Ltd. (listed on NASDAQ), an equity-method affiliate, occupies an important position financially.

Business Model

In the Entertainment-related Business, flow-type revenue from contract development, manufacturing, and sales of gaming machine control boards is the core business. In the IT-related Business, in addition to IoT communication device sales, subscription-type revenue such as the device management service "SunDMS" is being expanded. In the Global Data Intelligence Business, the company is accumulating stock-type revenue through subscription sales of Cellebrite products. Cellebrite's equity-method investment gains and gains from changes in equity contribute significantly to consolidated net income, forming the underlying structure.

Company Strengths

Acquired shares in Cellebrite in 2007 and continued to hold the company as an equity-method affiliate even after its NASDAQ listing in August 2021. In FY2026 (ending March 2026), the company recorded equity in earnings of affiliates of ¥4,969 million and gain on changes in equity of ¥4,727 million, which together account for the majority of consolidated net income of ¥9,664 million. This gives the company a financial structure capable of securing a high level of net income even when operating income is in deficit.

The company has built an integrated system covering planning, design, video production, programming, and control board manufacturing for pachinko and pachislot machines. It entered into a capital and business alliance with Fuji Shoji Co., Ltd. in 2013, and sales to Fuji Shoji in FY2026 (ending March 2026) reached ¥4,593,772 thousand (46.4% of total sales). The accumulation of expressive and technical capabilities through industry specialization underpins the company's strong product competitiveness.

The company holds patents related to 3G-to-LTE (4G) migration, maintaining a technological competitive advantage. Its Rooster Series (Industrial Network Equipment) achieves differentiation through dual-SIM redundancy functionality and integration with SunDMS, resulting in strong sales. It has a cumulative installation track record of over 500,000 units for beverage vending machines, forming a solid base for replacement demand.

ENVALITH's Perspective

Operating loss for FY2026 (ending March 2025) was ¥15 million, a further deterioration from the ¥1 million profit in the prior period. Revenue declined 8.6% to ¥9,907 million, marking the second consecutive year of decline. Ordinary profit of ¥5,133 million and net profit of ¥9,663 million relied on equity in earnings of affiliates of ¥4,969 million and gain on changes in equity of ¥4,728 million from Cellebrite, and the core earnings power of the mainstay business remains at a low level. The company forecasts operating profit of ¥2,131 million for FY2027 (ending March 2026), and whether this target is achieved will be the key focus for share price valuation.

The company forecasts revenue of ¥19,222 million (up 94.0% year on year), operating profit of ¥2,131 million, ordinary profit of ¥8,300 million, and net profit of ¥7,600 million, projecting a significant earnings recovery. The main drivers behind the projected doubling of revenue are the market launch of new products related to 5G and edge AI and a recovery in demand for gaming machines. However, given that delays in the rollout of new products became apparent in FY2026 (ending March 2025), and considering added uncertainty from the external environment (such as U.S. trade policy and rising energy prices), the probability of achieving this forecast needs to be carefully assessed.

In FY2026 (ending March 2025), the company acquired treasury shares worth ¥7,360 million (a substantial increase from the prior period), resulting in a large cash outflow of ¥8,088 million in financing activities. Although the equity ratio remained high at 89.7%, cash and cash equivalents at period-end were limited at ¥2,094 million. The balance of monetary trusts also shrank to ¥7,100 million (down ¥71,000 million from the prior period), and it will be necessary to closely monitor future investment capacity and dividend policy trends (the FY2027 (ending March 2026) dividend is currently undetermined).

Growth Strategy

Promoting a performance recovery plan targeting net sales of ¥19,222 million and operating profit of ¥2,131 million in FY2027 (ending March 2027)

In the IT-related Business, the company is promoting the rollout of new products such as the 5G-compatible device "DRX5510" and the Edge AI-equipped Edge Computer "LBX8110" to capture replacement demand following the shutdown of 3G services. In FY2026 (ending March 2026), delays in development and market launch were a factor in the revenue decline, but the plan positions this as the core driver of a significant revenue recovery in the FY2027 (ending March 2027) forecast.

The company is expanding subscription-based orders for forensic and intelligence solutions, primarily centered on Cellebrite products. In FY2026 (ending March 2026), contributions from a contracted project with the Ministry of Internal Affairs and Communications also helped achieve net sales of ¥1,293 million (up 8.2% year on year), but segment profit declined to ¥140 million (down 14.6%) due to deteriorating order conditions.

Through its consolidated subsidiary Sun Digital Health Co., Ltd., the company is preparing for the domestic launch of MyWaves Technologies Limited Products (Sleep Tech). In FY2026 (ending March 2026), the business remained at the stage of zero net sales and an operating loss of ¥30 million, with commercialization and the start of sales serving as the next key milestone.

In FY2026 (ending March 2026), the company conducted a share buyback of ¥7,360 million, raising net assets per share to ¥2,236.91 (up ¥101.67 year on year). By launching a BBT for executives and a J-ESOP for employees from August 2025, the company has strengthened its commitment to enhancing corporate value over the medium to long term by establishing a stock price- and performance-linked compensation system.
