    Notes to the Consolidated Financial Statements
    1. Reporting Entity

      Daiichi Sankyo Company, Limited (the "Company") is a public company domiciled in Japan. The addresses of its registered head office and principal business locations are disclosed on the Company's website (https://www.daiichisankyo.co.jp). The Company and its subsidiaries (collectively the "Group") are engaged in manufacturing and marketing of pharmaceutical products.

      The Group's consolidated financial statements for the year ended March 31, 2026 were approved on June 19, 2026 by Hiroyuki Okuzawa, Representative Director, President and CEO.

    2. Basis of Preparation
      1. Compliance with International Financial Reporting Standards

        The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards ("IFRS") under Article 312 of the Ordinance on Terminology, Forms, and Preparation Methods of Consolidated Financial Statements, as the Group meets the criteria of a "Specified Entity" defined under Article 1-2 of this ordinance.

      2. Basis of Measurement

        The Group's consolidated financial statements have been prepared on a historical cost basis except for certain financial instruments and other items as described in Note 3 "Material Accounting Policies."

      3. Functional Currency and Presentation Currency

        The Group's consolidated financial statements are presented in Japanese Yen ("JPY"), which is the functional currency of the Company. All financial information presented in JPY has been rounded down to the nearest million JPY.

      4. Changes in Accounting Policies

        The Material Accounting Policies adopted in preparing the consolidated financial statements of the Group have not changed from the prior year.

      5. Changes in Presentation

        (Consolidated Statement of Financial Position)

        "Long-term advance payments", which was included in "Other non-current assets" under non-current assets in the previous consolidated fiscal year, is disclosed separately for the fiscal year ended March 31, since the monetary significance has increased.

        To reflect this change in presentation, the Consolidated Statement of Financial Position as of March 31, 2025 has been reclassified on a consistent basis.

        As a result, the amount of JPY 254,104 million reported in "Other non-current assets" under non-current assets in the Consolidated Statement of Financial Position as of March 31, 2025 has been reclassified as "Long-term advance payments" of JPY 167,428 million and "Other non-current assets" of JPY 86,675 million.

        (Consolidated Statement of Cash Flows)

        "(Increase) decrease in long-term advance payments" and "Increase (decrease) in provisions", which were included in "Others, net" under cash flows from operating activities in the previous consolidated fiscal year, are disclosed separately for the fiscal year ended March 31, since the monetary significance has increased.

        To reflect this change in presentation, the Consolidated Statement of Cash Flows for the fiscal year ended March 31, 2025, has been reclassified on a consistent basis.

        As a result, the amount of JPY (136,972) million reported in "Others, net" under cash flows from operating activities in the Consolidated Statement of Cash Flows for the fiscal year ended March 31, 2025 has been reclassified as "(Increase) decrease in long-term advance payments" of JPY (50,488) million, "Increase (decrease) in provisions" of JPY (11,361) million and "Others, net" of JPY (75,122) million.

    3. Material Accounting Policies
      1. Basis of Consolidation

        1. Subsidiaries

          A Subsidiary is an entity that is controlled by the Group. The Group controls an entity if the Group has power over the entity, exposure, or rights, to variable returns from its involvement with the entity and the ability to use its power over the entity to affect the amount of its returns. Consolidation of a subsidiary begins from the date the Group obtains control of the subsidiary and ceases when the Group loses control of the subsidiary. Changes in a parent's ownership interest in a subsidiary that occur after obtaining the control over the subsidiary and that do not result in the parent losing control of the subsidiary are accounted for as equity transactions.

          All intra-group balances and transactions, and any unrealized gains and losses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements.

        2. Associates

          An associate is an entity over which the Group has significant influence but is not a subsidiary of the Group. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control of those policies.

          An investment is accounted for using the equity method from the date on which the Group has the significant influence until the date on which it ceases to have the significant influence over the investment.

          When significant influence over an associate is lost, and if there is still remaining ownership interest, the remaining equity interest is measured at fair value. The difference between the fair value and the carrying value at the date on which the equity method is discontinued, is recognized in profit or loss.

          Investment in associates includes acquired goodwill.

        3. Joint arrangements

          A joint arrangement is a contractual arrangement based on which two or more parties have joint control. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the activities that significantly affect the returns of the arrangement require the unanimous consent of the parties sharing control.

          The Group classifies its involvement with a joint arrangement as a joint operation when the Group has rights to the assets and obligations for the liabilities relating to the arrangement, and accounts for its share of the assets, liabilities, revenue and expenses in relation to its interest in the joint operation.

      2. Business Combinations

        Business combinations are accounted for using the acquisition method. The acquisition cost is measured as the sum of the consideration transferred, the amount of non-controlling interest in the acquiree, and in the case of an acquisition achieved in stages, the fair value of the previously held equity interest at the date of acquisition. The consideration transferred is measured at fair value at the date of acquisition. Non-controlling interests are measured either at fair value or at the proportionate share of the acquiree's identifiable net assets for each business combination.

        The excess of the acquisition cost over the Group's share of the acquiree's identifiable assets, liabilities, and contingent liabilities at fair value is recognized as goodwill. When the aggregate amount of the acquiree's identifiable assets, liabilities and contingent liabilities exceeds the acquisition cost, the resulting gain is recognized in profit or loss on the date of acquisition. Acquisition related costs are recognized as expenses in the period they are incurred.

      3. Foreign Currency Translation

        Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign currency monetary assets and liabilities are translated into the functional currency using the exchange rates at the end of the reporting period and the exchange differences arising on the settlement of monetary items or on translating monetary items are generally recognized in profit or loss. However, exchange differences arising from the translation of financial assets measured at fair value through other comprehensive income and cash flow hedges are recognized in other comprehensive income.

        Assets and liabilities of foreign operations (including goodwill and fair value adjustments arising on the acquisition of foreign operations) are translated into the presentation currency at the exchange rate at the end of the reporting period. Income and expenses of foreign operations are translated into the presentation currency at the average exchange rate for the period, except for the case that the exchange rates fluctuate significantly. When a subsidiary's functional currency is the currency of a hyperinflationary economy, adjustments are made to its separate financial statements to reflect current price levels, and income and expenses of the subsidiary are translated into the presentation currency at the exchange rate at the end of the reporting period.

        Exchange differences arising from translation of financial statements of foreign operations are recognized in other comprehensive income after the date of transition to IFRS. On the disposal of the entire interest in a foreign operation, or on the partial disposal of the interest in a foreign operation that involves the loss of control of a subsidiary or loss of significant influence over an associate, the cumulative amount of the exchange differences relating to that foreign operation, recognized in other comprehensive income and accumulated as a separate component of equity, is reclassified to profit or loss as a part of gain or loss on disposal.

      4. Financial Instruments

        1. Non-derivative Financial Assets

          1. Initial recognition and measurement

            Financial assets are recognized on the contract date when the Group becomes a party to the contractual provisions of the instruments.

            Financial assets, except for financial assets measured at fair value through profit or loss, are measured at fair value plus transaction costs that are attributable to the acquisition of the financial asset. However, trade receivables that do not contain a significant financing component are initially recognized at transaction price. At initial recognition, financial assets are classified as (a) financial assets measured at amortized cost; (b) financial assets measured at fair value through other comprehensive income; or (c) financial assets measured at fair value through profit or loss.

            1. Financial assets measured at amortized cost

              Financial assets are classified as financial assets measured at amortized cost if both of the following conditions are met:

              • the financial asset is held within a business model whose objective is to hold the financial asset in order to collect contractual cash flows: and

              • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

            2. Financial assets measured at fair value through other comprehensive income

              Debt instruments measured at fair value are classified as financial assets measured at fair value through other comprehensive income if both of the following conditions are met:

              • the financial asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling the financial asset: and

              • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

                For equity instruments measured at fair value, except for equity instruments held for trading which must be measured at fair value through profit or loss, the Group made an irrevocable election to present subsequent changes in fair value of certain equity instruments in other comprehensive income.

            3. Financial assets measured at fair value through profit or loss

              Financial assets, except for financial assets measured at amortized cost and financial assets measured at fair value through other comprehensive income, are classified as financial assets measured at fair value through

              profit or loss.

          2. Subsequent measurement

            After initial recognition, financial assets are measured based on their classification as follows:

            1. Financial assets measured at amortized cost

              Financial assets measured at amortized cost are measured at amortized cost using the effective interest method.

            2. Financial assets measured at fair value through other comprehensive income

              Changes in the fair value of debt instruments classified as financial assets measured at fair value through other comprehensive income are recognized in other comprehensive income, except for impairment gains or losses and foreign exchange gain and losses, which are recognized in profit or loss, and the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss as a reclassification adjustment when debt instruments are derecognized.

              Changes in the fair value of equity instruments designated as financial assets measured at fair value through other comprehensive income are recognized in other comprehensive income, and the accumulated amount of other comprehensive income is transferred to retained earnings when equity instruments are derecognized or the decrease in fair value compared to acquisition cost is significant.

            3. Financial assets measured at fair value through profit or loss

              Financial assets measured at fair value through profit or loss are measured at fair value, and any changes in fair value are recognized in profit or loss.

          3. Derecognition

            Financial assets are derecognized when the contractual rights to the cash flows from the asset expire or are transferred in a transaction in which substantially all the risks and rewards of ownership of the asset are transferred to another entity.

        2. Impairment of Financial Assets

          At the end of each reporting period, the Group evaluates whether the credit risk on financial assets measured at amortized cost has increased significantly since initial recognition, and a loss allowance for expected credit losses on such financial assets is recognized.

          If the credit risk on financial assets has not increased significantly since initial recognition, a loss allowance is measured at an amount equal to 12-month expected credit losses. If the credit risk on financial assets has increased significantly since initial recognition, a loss allowance is measured at an amount equal to lifetime expected credit losses. However, a loss allowance for trade receivables that do not contain a significant financing component is measured at an amount equal to lifetime expected credit losses.

          The Group considers, as a general rule, that there has been a significant increase in the credit risk when payments have not been made for more than 30 days passed contractual due date. The Group considers not only the information regarding due date but also other reasonable and supportable information when determining whether credit risk has increased significantly since initial recognition. The Group considers that there has not been a significant increase in the credit risk when the financial assets are determined to have low credit risk at the end of reporting period.

          Expected credit losses on financial assets are measured in a way that reflects the following factors:

          • an unbiased and probability-weighted amount that is determined by evaluating a range of possible outcomes;

          • the time value of money; and

          • reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of future economic conditions.

          Expected credit losses are measured based on the discounted present value of the differences between the contractual cash flows and the cash flows expected to be received. When expected credit losses are recognized, the carrying amount of the financial asset is reduced through use of a loss allowance for expected credit losses and expected credit losses are recognized in profit or loss. If, in a subsequent period, the amount of the expected credit losses decreases, the previously recognized credit losses are reversed by adjusting the loss allowance and the reversal is recognized in profit or loss. The carrying amount of financial assets measured at amortized cost is reduced directly when they are expected to become uncollectible in the future and all collaterals are implemented

          or transferred to the Group.

        3. Non-derivative Financial Liabilities

          1. Initial recognition and measurement

            Financial liabilities are classified as financial liabilities measured at amortized cost or financial liabilities measured at fair value through profit or loss at initial recognition.

            At initial recognition, financial liabilities are measured at fair value and, in the case of financial liabilities at amortized cost, the transaction costs that are directly attributable to the issue of the financial liabilities are deducted.

          2. Subsequent measurement

            After initial recognition, financial liabilities are measured based on classification as follows:

            1. Financial liabilities measured at amortized cost

              Financial liabilities measured at amortized cost are measured at amortized cost using the effective interest method. Amortization using the effective interest method and gains or losses arising from termination of recognition are recognized in profit or loss.

            2. Financial liabilities measured at fair value through profit or loss

              Financial liabilities measured at fair value through profit or loss are measured at fair value through profit or loss.

          3. Derecognition

            Financial liabilities are derecognized when the obligation is discharged, cancelled or expired.

        4. Offsetting Financial Assets and Liabilities

          Financial assets and financial liabilities are offset only when the Group has a legally enforceable right to offset the recognized amounts and intends to settle on a net basis or to realize the asset and settle the liability simultaneously.

        5. Derivatives and Hedge Accounting

          Derivatives are utilized to hedge foreign currency risk and interest rate risk. The derivatives primarily used by the Group include forward foreign exchange contracts and interest-rate swaps.

          At the inception of the hedging relationship the Group formally designates and documents the hedging relationship and the entity's risk management objective and strategy for undertaking the hedge. The documentation includes identification of the hedging instrument, the hedged item, the nature of the risk being hedged and how the entity will assess whether the hedging relationship meets the hedge effectiveness requirements.

          The Group assesses at the inception of the hedging relationship, and on an ongoing basis, whether the hedging relationship meets the hedge effectiveness requirements. At a minimum, the Group performs the ongoing assessment at each reporting date or upon a significant change in the circumstances affecting the hedge effectiveness requirements, whichever comes earlier.

          Derivatives are initially recognized at fair value with transaction costs recognized in profit or loss when they are incurred. After initial recognition, derivatives are measured at fair value.

          Hedges that meet the criteria for hedge accounting are accounted for as follows:

          1. Fair value hedges

            Changes in the fair value of the hedging instruments are recognized in profit or loss. Changes in the fair value of hedged items attributable to the hedged risks are recognized in profit or loss, adjusting the carrying amount of the hedged item.

          2. Cash flow hedges

            The effective portion of changes in fair value of hedging instruments is recognized in other comprehensive income, while the ineffective portion is recognized immediately in profit or loss. The cumulative amounts of changes in fair value of hedging instruments recognized in other comprehensive income are reclassified from equity to profit or loss in the same period or periods when the hedged forecast cash flows or hedged items affect profit or loss. If hedged items result in the recognition of non-financial assets or non-financial liabilities, the cumulative amounts recognized in other comprehensive income are accounted for as adjustments in the carrying amount of the non-financial assets or non-financial liabilities. When forecast transactions or firm commitments are no longer expected to occur, any related cumulative gain or loss that has been recognized in other comprehensive income is reclassified from equity to profit or loss. The Group discontinues hedge accounting prospectively only when the hedging relationship ceases to meet the qualifying criteria. This includes instances when the hedging instrument expires or is sold, terminated or exercised.

      5. Cash and Cash Equivalents

        Cash and cash equivalents comprise cash on hand, readily available bank deposits, and short-term, highly liquid investments having maturities of three months or less that are readily convertible to known amounts of cash and subject to an insignificant risk of changes in value.

      6. Inventories

        Inventories are measured at the lower of cost and net realizable value. Costs of inventories comprise cost of raw materials, direct labor and other costs directly attributable to the inventories and cost of related production overheads. The cost of inventories is assigned by using the weighted average cost formula. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

      7. Property, Plant and Equipment

        Property, plant and equipment is carried at cost less any accumulated depreciation and any impairment losses.

        The cost of an item of property, plant and equipment includes any costs directly attributable to the acquisition of the asset, costs of dismantlement, removal and restoration as well as borrowing costs eligible for capitalization.

        An item of property, plant and equipment, except for land, is depreciated by the straight-line method based on the estimated useful life of the asset. The estimated useful lives of major items of property, plant and equipment are as follows:

        • Buildings and structures: 15 to 50 years

        • Machinery and vehicles: 4 to 8 years

        The depreciation method, the residual value and the useful life of an item of property, plant and equipment are reviewed at least annually and adjusted as necessary.

      8. Goodwill and Intangible Assets

        1. Goodwill

          Goodwill is measured at cost less accumulated impairment loss and is not amortized. Goodwill arising from a business combination is allocated to cash-generating units or groups of cash-generating units that are expected to benefit from the synergies of the business combination.

        2. Intangible Assets

          Among rights related to products or research and development acquired separately or through business combinations, those that are still in the research and development stage or those for which marketing approval has not yet been obtained from the regulatory authorities are recognized under intangible assets as "IPR&D."

          The cost of a separately acquired intangible asset is measured at cost and the cost of an intangible asset acquired in a business combination is measured at its fair value at the acquisition date. After initial recognition, the Group applies the cost model and intangible assets are carried at cost less any accumulated amortization and any accumulated impairment loss.

          Internally generated research expenditure is recognized as an expense when it is incurred. Internally generated development expenditure is recognized as an intangible asset if all the criteria for capitalization can be demonstrated. However, due to the uncertainties relating to the research and development duration and process, it is considered that the criteria for capitalization are not met until marketing approval from a regulatory authority is obtained. Therefore, internally generated development expenditure is recognized as an expense when it is incurred. Subsequent expenditure, including initial upfront and milestone payments to the third parties, on an acquired IPR&D is capitalized if, and only if, it is probable that the expected future economic benefits that are attributable to the asset will flow to the Group and the asset is identifiable.

          An intangible asset recognized as IPR&D is not amortized because it is not yet available for use, but instead, it is tested for impairment annually at the same time each year or whenever there is an indication of impairment.

          Once marketing approval from the regulatory authorities is obtained and the asset is available for use, IPR&D is transferred to Commercial rights.

          Acquisition cost and development expenditure of software for internal use is recognized as an intangible asset if it can be demonstrated that the asset will generate probable future economic benefits.

          Intangible assets with finite useful lives are amortized by the straight-line method based on the estimated useful life of the asset, beginning from when the assets are available for use. The estimated useful lives of major items of intangible assets are as follows:

          - Commercial rights: 9 to 18 years

          The amortization method, the residual value and the useful lives of intangible assets are reviewed at least annually and adjusted as necessary.

      9. Leases

        1. As a lessee

          The Group recognizes a right-of-use asset and a lease liability at the lease commencement date.

          A right-of-use asset is initially measured at cost and is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term. The estimated useful lives of right-of-use assets are determined on the same basis as those of tangible fixed assets. In addition, a right-of-use asset is reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

          A lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group's incremental borrowing rate.

          Lease payments are allocated to financial expenses and repayments of lease liabilities so that the interest expenses each period during the lease term will result in a constant interest rate on the outstanding lease liability.

          A lease liability is remeasured when there is a change in future lease payments arising from a change in an index or rate, or if the Group changes its assessment of whether it will exercise a purchase, extension or termination option. When a lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.

          The Group has elected not to recognize right-of-use assets and lease liabilities for short-term leases and leases of low-value assets. The Group recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.

        2. As a lessor

          The Group determines at lease inception whether each lease is a finance lease or an operating lease.

          To classify each lease, if the lease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset, then it is a finance lease; if not, then it is an operating lease.

          When the Group is an intermediate lessor, it accounts for its interests in the head lease and the sub-lease separately. It assesses the lease classification of a sub-lease with reference to the right-of-use asset arising from the head lease, not with reference to the underlying asset. If a head lease is a short-term lease to which the Group applies the exemption described above, then it classifies the sub-lease as an operating lease.

      10. Impairment of Non-financial Assets

        The Group assesses annually whether there is any indication that a non-financial asset or cash-generating unit that generates cash inflows may be impaired.

        If there is any indication that an asset or cash-generating unit may be impaired, the recoverable amount of the asset is estimated. Goodwill, intangible assets with indefinite lives, and intangible assets not yet available for use are not amortized but are tested for impairment annually or at any time there is an indication that an asset may be impaired. The recoverable amount of an asset or a cash-generating unit is the higher of its fair value less costs of disposal and its value in use, which is calculated based on the risk-adjusted future cash flows discounted by an appropriate discount rate.

        If the carrying amount of an asset or a cash-generating unit exceeds the recoverable amount, an impairment loss is recognized in profit or loss and the carrying amount is reduced to the recoverable amount.

        An impairment loss recognized for goodwill is not reversed in a subsequent period. It is assessed whether there is any indication that an impairment loss recognized in prior periods for an asset other than goodwill may no longer exist or may have decreased. If any such indication exists, the recoverable amount of the asset or cash-generating unit is estimated. If the recoverable amount exceeds the carrying amount of the asset or cash-generating unit, an impairment loss recognized in prior periods is reversed and the carrying amount of the asset is increased to the recoverable amount. The reversal of the impairment loss is recognized in profit or loss. The increased carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss does not exceed the carrying amount that would have been determined (net of amortization or depreciation) if no impairment loss had been recognized for the asset in prior years.

      11. Non-current Assets Held for Sale and Discontinued Operations

        A non-current asset, or disposal group comprising assets and liabilities, is classified as asset held for sale if its carrying amount will be recovered primarily through sale rather than continuing use. The asset or disposal group is classified as held for sale only if it is available for immediate sale in its present condition, and the sale is highly probable meaning that the appropriate level of management of the Group is committed to the sale and principally that the sale is expected to be completed within one year. After the asset or disposal group is classified as held for sale, it is measured at the lower of its carrying amount and fair value less costs to sell and is not depreciated or amortized.

        Discontinued operations include a component of an entity that either has been disposed of or is classified as held-for-sale, and represents a separate major line of business or geographic area of operations.

      12. Employee Benefits

        1. Post-employment Benefits

          1. Defined benefit plans

            The present value of defined benefit obligations and related current service cost and, where applicable, past service cost are determined using the projected unit credit method for each plan separately.

            The discount rate is determined by reference to market yields at the end of the reporting period on high-rated corporate bonds, reflecting the estimated timing of benefit payments.

            Net defined benefit liabilities or assets are calculated by deducting the fair value of the plan assets from the present value of the defined benefit obligations.

            If the defined benefit plan has surplus, the defined benefit asset is limited to the asset ceiling that is the present value of any future economic benefits available in the form of reductions in the future contributions to the plan or cash refunds.

            Past service costs are recognized in profit or loss as incurred.

            Remeasurements of defined benefit plans are recognized in other comprehensive income in the period when they are incurred and transferred to retained earnings immediately.

            Service costs and net interest on the net defined benefit liabilities (assets) are recognized in profit or loss.

          2. Defined contribution plans

            The contributions to defined contribution plans are recognized as expenses when the related service is rendered by the employees.

        2. Others

          Short-term employee benefits are not discounted and are recognized as expenses when the related service is rendered by the employees. The expected costs of accumulating short-term compensated absences are recognized as liabilities when the Group has present legal or constructive obligations to pay as a result of past employee service and when reliable estimates of the obligation can be made.

      13. Provisions

        A provision is recognized when there is a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation.

        An onerous contract is a contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under the contract. When the Group has an executory contract that includes an onerous contract, the present obligation under the contract is recognized as a provision.

        When the effect of the time value of money is material, the amount of a provision is measured at the present value of the expenditures expected to be required to settle the obligation. The present value is determined by using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks inherent in the liabilities. The increase in the carrying amount of a provision reflecting the passage of time is recognized as a financial expense.

      14. Treasury Shares

        Treasury shares are recognized as a deduction from equity. No gain or loss is recognized on the purchase, sale or cancellation of the treasury shares. Any difference between the carrying amount and the consideration paid is recognized in capital surplus.

      15. Share-based Payments

        The Company and certain of its subsidiaries operate an equity-settled share-based payment plan and a cash-settled share-based payment plan as share-based payment plans.

        1. Equity-settled share-based payment plan

          The shares are measured at the fair value at the date of grant based on the fair value of the equity instrument granted, and recognized as expenses over the vesting period, with a corresponding increase in equity.

        2. Cash-settled share-based payment plan

          The fair value of the amount of payments is recognized as an expense with a corresponding liability. The change in the fair value of the liability at each reporting date is recognized in profit or loss until the liability is settled.

      16. Revenue

        Revenue from contracts with customers is recognized by applying the following five steps: Step 1: Identify the contract with a customer

        Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price

        Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation

        1. Sales of finished goods and merchandise

          Revenue from sale of finished goods and merchandise is recognized when the performance obligation is satisfied, considering the following indicators:

          • the Group has a present right to payment for the asset;

          • the customer has legal title to the asset;

          • the Group has transferred physical possession of the asset; and

          • the customer has accepted the asset.

            Revenue is measured at the amount after deducting the impact of trade discounts, cash discounts, rebates and returns from the consideration promised in the contract.

        2. License fee revenue

        Revenue arising from license agreements is recognized at a point in time or over time depending on the content of performance obligation(s).

        Variable consideration from contracts with customers are included in the transaction price only to the extent that is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

      17. Government Grants

        Government grants are recognized at fair value when there is reasonable assurance that the Group complies with the conditions attached to them and that the grants will be received.

        Government grants which are intended to compensate specific costs are recognized in profit or loss on a systematic basis over the period in which the Group recognizes the corresponding expenses.

        Government grants related to assets are recognized as deferred revenue and recognized in profit or loss on a systematic basis over the estimated useful lives of the relevant assets.

      18. Income Taxes

        Income taxes comprise current and deferred income taxes.

        Current income taxes are measured at the amount expected to be paid to or recovered from the taxation authorities, using the tax rates that have been enacted or substantively enacted by the end of the reporting period. They are recognized in profit or loss, except to the extent that the taxes arise from transactions or events which are recognized either in other comprehensive income or directly in equity, or the taxes arise from business combinations.

        Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates that have been enacted or substantively enacted by the end of the reporting period. Deferred tax assets and liabilities are recognized for temporary differences between the carrying amount of assets or liabilities for accounting purpose and the tax basis, and unused tax losses and tax credits.

        Deferred tax assets are recognized to the extent that it is probable that future taxable profit will be available against which they can be utilized.

        When uncertainties exist if the taxing authorities will accept a particular tax treatment, the said uncertainties are reflected when determining the taxable profit, the carrying amount for the tax basis, unused tax losses and tax credits, and the tax rate.

        Deferred tax assets and liabilities are not recognized for temporary differences that arise from the initial recognition of goodwill or that arise from the initial recognition of assets or liabilities in transactions which are not business combinations and which do not give rise to equal taxable and deductible temporary differences at the time of the transaction and affect neither accounting profit nor taxable profit or tax loss.

        Deferred tax liabilities for taxable temporary differences associated with investments in subsidiaries and associates are recognized, except to the extent that the Group is able to control the timing of the reversal of the temporary differences and that it is probable that the temporary differences will not reverse in the foreseeable future. Deferred tax assets for deductible temporary differences arising from investments in subsidiaries and associates are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized.

        Deferred tax assets and deferred tax liabilities are offset if there is a legally enforceable right to offset current tax assets against current tax liabilities and the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on the same taxable entity.

    4. Significant Accounting Judgments, Estimates and Assumptions

      The preparation of these consolidated financial statements requires management of the Group to make judgments, estimates and assumptions that affect the amount of reported income, expenses, assets and liabilities as well as disclosure of contingent liabilities. However, due to uncertainty in the estimates and assumptions, it is possible that significant adjustments to carrying amounts of assets and liabilities may be required in future periods.

      Significant items that required management to make estimates and judgments are as follows:

      • Impairment of non-financial assets (Note 13. Property, Plant and Equipment, Note 14. Goodwill and Intangible Assets)

      • Provisions (Note 19. Provisions)

      • Measurement of defined benefit obligations (Note 20. Employee Benefits)

      • Revenue recognition (Note 24. Revenue)

    5. Standards and Interpretations Issued but Not Yet Adopted

      The new and revised accounting standards and interpretations that have not been early adopted by the group are mainly as follows.

      The Group is still in the progress of assessing the impact of adopting IFRS 18 on its consolidated financial statements.

        Year ended March 31, 2026

        There were no significant business combinations for the fiscal year ended March 31, 2026.

      2. Contingent consideration

        The "contingent consideration" arises from the business combinations of HBT Labs, Inc.

        The contingent consideration for the business combination with HBT Labs, Inc. is the estimated amount of future milestone payments and royalty payments over a certain period based on sales of the development pipeline, taking into account the time value of money.

        The total amount of future payments that the Company may be required to make for all future milestones under the contingent consideration agreement is JPY3,198 million (before discount). There is no upper limit on the royalty payments to be made based on future sales of the development pipeline, and the estimated payment amounts are calculated based on future forecast sales. The exposure to foreign currency exchange risks at the reporting date is 9,667 thousand U.S. dollars. The impact of a 1% appreciation in the Yen against the U.S. dollar on profit before tax is JPY15 million at the reporting date.

        The fair value hierarchy level for this contingent consideration is Level 3. The fair value change of contingent consideration is recognized in "Financial income" or "Financial expenses." The fair value hierarchy is summarized in Note 30 "Financial Instruments."

        Reconciliation of the movement in the contingent consideration which is classified as Level 3 from the opening balances to the ending balances is as follows:

The amount of expensed research and development expenditure were JPY435,965 million and JPY466,005 million for the fiscal years ended March 31, 2025 and 2026, respectively.

      4. Impairment of Goodwill

        The Group performs impairment testing for goodwill annually and at any time there is an indication that goodwill may be impaired. Impairment tests for goodwill for the cash-generating unit of the prescription drug business were performed as follows:

        The recoverable amount was estimated based on value in use using the mid-term plan through fiscal 2030, which was approved by management, and the valuation included a terminal value assuming a growth rate of 0% after fiscal 2031.

        The value in use was calculated using a pre-tax discount rate and exceeded the carrying amount, therefore no impairment loss was recognized for the fiscal year ended March 31, 2026. The pre-tax discount rates for the fiscal year ended March 31, 2025 and 2026 were 8.2% and 7.7%, respectively. The value in use exceeded the carrying amount, and the Group determined that the possibility of the value in use becoming lower than the carrying amount was remote, even if the discount rate were to increase within a reasonable range.

      5. Impairment of Intangible Assets

        The Group performs impairment testing for intangible assets which indicate impairment at all such times and for intangible assets not yet available for use annually and at any time there is an indication that an asset may be impaired.

        The recoverable amount of an intangible asset is the higher of its fair value less costs of disposal and its value in use, which is calculated based on risk-adjusted future cash flows discounted by an appropriate discount rate. If the carrying amount of an intangible asset exceeds the recoverable amount, an impairment loss is recognized in profit or loss and the carrying amount is reduced to the recoverable amount.

        For measurement of the value in use, the Group considers the possibility that the manufacturing and marketing of new products are approved, sales forecasts of products and other factors. Due to uncertainty in the underlying assumptions, it is possible that actual results may differ and, as a result, significant adjustments in the amount of intangible assets may be required in the consolidated financial statements for the year ending March 31, 2027.

        As a result of the impairment testing, impairment losses of JPY2,970 million and JPY1,127 million were recognized for the fiscal years ended March 31, 2025 and 2026, respectively, and recorded in "Selling, general and administrative expenses" and "Research and development expenses" in the consolidated statement of profit or loss.

        Notes:

        1. The Company is subject to corporate tax, inhabitant tax, and enterprise tax, which is tax deductible against taxable income for corporate tax purposes when paid. The applicable tax rate based on these taxes was 30.5% for the fiscal years ended March 31, 2025 and 2026. The statutory tax rate applied in the calculation of deferred tax assets and liabilities was 30.5% for amounts expected to be recovered or settled during the period from April 1, 2025 to March 31, 2026 in the year ended March 31, 2025, and 31.4% for those expected to be recovered or settled on or after April 1, 2026, in the year ended March 31, 2025, and 31.4% in the year ended March 31, 2026. Overseas operations are subject to income taxes of the jurisdictions in which they are located.

        2. Tax credit for research and development expenses mainly arises in Japan and the United States.

        3. In the year ended March 31, 2025, "Impact of liquidation of consolidated subsidiaries" that were included in "Others" have been separately presented starting from the year ended March 31, 2026, as their monetary materiality has increased. Accordingly, the comparative information has been reclassified.

      7. Global Minimum Tax

        In Japan, a corporate tax corresponding to the global minimum tax was established in the 2023 tax reform (hereinafter referred to as "Japan's Global Minimum Tax"), and the Tax Reform Act ("Act for Partial Revision of the Income Tax Act, etc." (Act No. 3 of 2023)) (hereinafter referred to as the "Revised Corporation Tax Act"), together

        with provisions related to it, was enacted on March 28, 2023. The Revised Corporation Tax Act introduced the Income Inclusion Rule (IIR), which is one of the BEPS Global Minimum Tax rules (hereinafter referred to as "Pillar Two model rules"). Effective from the fiscal year ended March 31, 2025, an additional tax has been imposed on parent companies located in Japan until the tax burden of their subsidiaries and other affiliated entities reaches the minimum tax rate (15%).

        The Group has applied the temporary exemption set forth in IAS 12 "Income Taxes" and has not recognized deferred tax assets and liabilities related to income taxes arising from tax law enacted or substantively enacted to implement the Pillar Two model rules (hereinafter referred to as "Pillar Two income taxes"), also has not included such amounts in the financial statement disclosures.
