Booost Sustainability Enhances Support for Early SSBJ Disclosure with New Functional Expansions

Booost Inc. (Shinagawa, Tokyo; CEO: Hironori Aoi), a provider of the market-leading "Sustainability ERP" and advocate for addressing the "Sustainability 2026 Problem," has announced major functional enhancements to its "booost Sustainability" platform. These updates, specifically the "Estimation and Forecast Management Function" and "Enterprise ID Governance (Multi-SSO)," are designed to support large enterprises in meeting the early disclosure requirements of the Sustainability Standards Board of Japan (SSBJ).

### Background: The Challenge of Accelerated Disclosure Timelines Under the Financial Services Agency’s current direction, Prime-listed companies in Japan will be required to disclose sustainability information in their annual securities reports starting as early as the fiscal year ending March 2027 (for companies with market caps of 3 trillion yen or more). This shifts the reporting deadline to within three months of the fiscal year-end, effectively requiring companies to finalize non-financial data three to six months earlier than previous voluntary reports. This acceleration demands financial-grade control, accuracy, and speed across global supply chains.

### Key Functional Enhancements 1. **Estimation and Forecast Management Function** This feature allows enterprises to perform logic-based calculations for missing data points at the time of disclosure. By utilizing unit consumption data (based on floor area or headcount), the system can estimate GHG emissions and other non-financial metrics for outstanding locations. It also supports automatic forecasting for the remaining periods of a fiscal year based on actual results, ensuring that disclosures remain audit-ready and reduce dependency on manual, error-prone spreadsheets.

2. **Multi-SSO / Enterprise ID Governance** To support large groups with diverse IT infrastructures, the platform now allows domain-specific authentication policies. This enables seamless integration with various identity providers (such as Azure AD or Google Workspace) across global subsidiaries, ensuring unified access control and high security standards essential for corporate governance.

### Looking Ahead Booost Inc. aims to transform non-financial data from a mere compliance requirement into a strategic "management infrastructure." By facilitating early and accurate disclosure, the company supports Sustainability Transformation (SX) and enhances the global corporate value of Japanese firms.
