**■Background and Overview**

The two companies announced a capital and business alliance in February 2026. This collaboration is one of the concrete initiatives under that alliance.

With the mandatory application of new lease accounting standards scheduled for April 2027, accounting departments are expected to face a significant increase in workload. To meet the urgent needs of businesses in this situation, a genuine AI solution is considered indispensable. This solution aims to combine Proship's expertise in fixed asset and lease management, including IFRS 16 compliance (with over 100 companies' implementation records), with First Accounting's specialized AI knowledge in the accounting field, to provide a highly accurate solution truly needed by the frontline.

In preparing for the application of the new lease accounting standards, corporate accounting personnel face the following practical challenges:

* Occurrence of work related to collecting, inputting, and managing scattered contracts. * Subjectivity in the identification and judgment of leases (judgment fluctuation) and disclosure risk due to misjudgment. * Estimation of impact and system adaptation based on the new lease accounting standards.

This collaboration, linking First Accounting's "Accounting AI Agent (New Lease Accounting Standards)" and Proship's "New Lease Accounting Impact Estimation Solution," solves these challenges.

* Identification and judgment of leases by reading contracts. * Efficient data linkage of necessary information for impact estimation. * Highly accurate impact estimation based on new lease accounting standards. * Creation of lease data necessary for new lease accounting system adaptation.

**■Solution Features**

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 identifies and judges leases from contracts but also consistently supports the organization of company-specific judgment criteria rules, the construction and management of contract databases based on contracts, and the visualization of judgment processes in anticipation of audit responses.

Supports decision-making by visualizing data from multiple perspectives. * **Question flowchart usable for audit response:** ... Improves transparency and reliability of audit responses by visualizing and recording the judgment process.

**■Comment from Motofumi Suzuki, Representative Director and President of Proship**

Under our basic philosophy "Speciality for Customer," we believe it is our mission at Proship to contribute to companies' new lease accounting compliance through our expertise in fixed asset and lease management. With the mandatory application of new lease accounting standards approaching in April 2027, corporate accounting departments are facing an unprecedented workload. Amidst this, expectations for AI technology are high, but in the stringent field of accounting, performing "auditable judgments at a practical level" with AI has been by no means easy.

This collaborative solution, which infuses the lease management knowledge gained from over 100 IFRS 16 implementations by our company into the AI of First Accounting, a top runner in accounting-specific AI, fundamentally solves this problem.

The "genuine" convergence of the deep expertise of both companies...
