TOKYO, April 25, 2024 – Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, “Astellas”) today announced that at the meeting of the Board of Directors held today, it decided to change the definition of core basis in consolidated financial statements from the fiscal year 2024 (FY2024) ending March 31, 2025 onward.

Astellas has been applying International Financial Reporting Standards to consolidated financial statements since FY2013, which ended March 31, 2014, and disclosing financial results on a core basis. Astellas will change the definition of core basis from FY2024 and will newly exclude amortisation of intangible assets, gain on divestiture of intangible assets, and share of profit (loss) of investments accounted for using the equity method from the financial results on a full basis as certain significant adjusted items defined by the company.



<New Definition of Core Basis>
The Company discloses financial results on a core basis as an indicator of its profitability. Certain significant adjusted items defined by the Company that are reported in financial results on a full basis are excluded from these financial results on a core basis. These adjusted items include amortisation of intangible assets, gain on divestiture of intangible assets, share of profit and loss of investments accounted for using equity method, impairment losses, gain/loss on sales of property, plant and equipment, restructuring costs, loss on disaster, a large amount of losses on compensation or settlement of litigations and other legal disputes, and certain other items defined by the Company.

<The background to the change>
As a result of the acquisition of Iveric Bio, the amortisation of intangible assets significantly increased, and the conventional definition could not appropriately reflect the profitability of Astellas, making it difficult to understand performance trends and compare with other companies. The new definition of core basis will function as an indicator that more accurately reflects Astellas’ profitability and facilitates easier comparison with global pharmaceutical companies from a financial standpoint.
