Background and Purpose Both companies announced a capital and business alliance in February 2026. This collaboration is one of the concrete initiatives of that partnership. With the mandatory application of the new lease accounting standards scheduled for April 2027, accounting departments are expected to face an increased workload. To meet the urgent needs of these companies, we believe that a genuine AI solution is indispensable. Proship possesses expertise in fixed asset and lease management, including IFRS 16 compliance, while First Accounting specializes in AI for the accounting field. By combining the specialized knowledge of both, we aimed to provide a highly accurate solution that truly meets the needs of the field. In preparing for the application of the new lease accounting standards, corporate accounting personnel face the following practical challenges: ● Occurrence of tasks related to collecting, inputting, and managing dispersed contracts ● Personalization of lease identification and judgment (fluctuation in judgment) and disclosure risk due to misjudgment ● Estimation of impact and system adaptation based on the new lease accounting standards This collaboration between First Accounting's "Accounting AI Agent (New Lease Accounting Standards)" and Proship's "New Lease Accounting Impact Estimation Solution" resolves these challenges: ● Lease identification and judgment by reading contracts ● Efficient data linkage for information necessary for impact estimation ● Highly accurate impact estimation based on the new lease accounting standards ● Creation of lease data necessary for system adaptation to new lease accounting

Features of the Collaborative Solution This collaborative solution, combining Proship's "New Lease Accounting Impact Estimation Solution" and First Accounting's "Accounting AI Agent (New Lease Accounting Standards)," not only reads, identifies, and judges contracts but also consistently supports the organization of judgment criteria rules for each company, the construction and management of a contract database based on contracts, and the visualization of the judgment process with an eye on audit compliance. ● Creation of judgment data that considers the requirements of each company Flexible judgment becomes possible, reflecting each company's unique accounting policies and requirements. ● Database of appropriate judgments based on contracts Accurate judgment information can be accumulated based on contracts, rather than asset data. ● Flexible visualization of amounts, numbers, etc. Data is visualized from multiple perspectives, supporting rapid decision-making by accounting departments. ● Question flowchart usable for audit compliance By visualizing and recording the judgment process, transparency and reliability in audit compliance are improved.

Shishi Suzuki, Representative Director and President, Proship Under our corporate philosophy of "Speciality for Customer," we believe it is Proship's mission to contribute to companies' new lease accounting compliance through our expertise in fixed asset and lease management. With the mandatory application of the new lease accounting standards approaching in April 2027, corporate accounting departments are facing an unprecedented workload. In this context, expectations for AI technology are high, but in the strict field of accounting, "practical level judgment that can withstand audits" by AI has never been easy. This collaborative solution, which combines the AI of First Accounting, a top runner in accounting-specific AI, with our company's lease management expertise based on over 100 IFRS 16 compliance achievements, fundamentally solves this problem. This "true" solution, where the deep expertise of both companies is concentrated.
