Significant Accounting Policies [Abstract] |
General principles, Statement of Compliance and Basis of Presentation | General principles The statement of consolidated financial position as of and for the years ended December 31, 2024 and 2023, the statements of consolidated operations, the statements of consolidated comprehensive income (loss), the statements of consolidated changes in shareholders’ equity and the statements of consolidated cash flows for the years ended December 31, 2024, 2023 and 2022, and related notes to financial statements were prepared under management’s supervision and were approved by the Executive Board of the Company (the “Executive Board”) and reviewed by the Supervisory Board of the Company (the “Supervisory Board”) on April 2, 2025. All amounts presented in the consolidated financial statements are presented in thousands of euros, unless stated otherwise. Some figures have been rounded. Accordingly, the totals in some tables may not be the exact sums of component items. The preparation of the consolidated financial statements in accordance with IFRS Accounting Standards requires the use of estimates and assumptions that affect the amounts and information disclosed in the financial statements (see Note 3.2. - Use of judgement, estimates and assumptions for additional information). The consolidated financial statements have been prepared using the historical cost measurement basis, with the exception of some financial assets and liabilities, which are measured at fair value. Statement of Compliance and Basis of Presentation The Company has prepared these consolidated financial statements in accordance with International Financial Reporting Standards as adopted by the European Union and IFRS ® Accounting Standards as issued by the International Accounting Standard Board (‘IASB’). The accounting principles used to prepare the consolidated financial statements for the fiscal year ended December 31, 2024 are identical to those used for the previous year except for the standards listed below that required adoption in 2024. Application of New or Amended Standards and Interpretations The Company adopted the following standards, amendments and interpretations, whose application was mandatory for period beginning on or after January 1, 2024: •Amendment to IFRS 16 – Lease liability in a sale and leaseback •Amendment to IAS 1 – Classification of liabilities as current or non-current and non-current liabilities with covenants •Amendment to IAS 7 and IFRS 7 - Supplier finance arrangements Those amendments had no material impact on the consolidated financial statements of the Company for the year ended December 31,2024. Assessment of the impacts of the Application of the standards, amendments and interpretations which will come into force subsequently The new standards, interpretations and amendments to existing standards that have been published but are not yet applicable concern: •Amendments to IAS 21 - Lack of Exchangeability - as of January 1, 2025 •Amendments to IFRS 9 and IFRS 7 - Amendments to the Classification and Measurement of Financial Instruments - as of January 1, 2026 •Annual Improvements to IFRS Accounting Standards as of January 1, 2026 – Amendments to: ◦IFRS 1 First-time Adoption of International Financial Reporting Standards; ◦IFRS 7 Financial Instruments: Disclosures and its accompanying Guidance on implementing IFRS 7; ◦IFRS 9 Financial Instruments; ◦IFRS 10 Consolidated Financial Statements; and ◦IAS 7 Statement of Cash flows •New standard - IFRS 18 - Presentation and Disclosure in Financial Statements - as of January 1, 2027 •New standard - IFRS 19 - Subsidiaries without Public Accountability : Disclosures - as of January 1, 2027 These new standards, interpretations and amendments are under analysis to see if there are applicable to the Company. The Company elected to early adopt no new standards, amendments or interpretations which application was not yet mandatory for the year ended December 31, 2024. Going concern The Company has prepared its consolidated financial statements assuming that it will continue as a going concern. Although the Company recognized significant cash inflows in 2023, derived from net proceeds from the equity offering and upfront payment from the global licensing, co-development, and commercialization agreement with Janssen, achieving its transition towards a profitability situation will depend on generating sufficient revenue to support its cost structure and achieving development, regulatory, sales milestones and royalties related to the Janssen Agreement. Therefore, the Company cannot assure that it will ever be profitable or generate positive cash flow from operating activities. Furthermore, the Company may face unforeseen challenges, complications, development delays, and other unknown factors that may incur additional expenses. The Company recorded net losses of €68.1 million in 2024, accumulated losses totalling €380.4 million since inception, inclusive of the 2024 net loss. For the year ended December 31, 2024 the Company generated negative €25.5 million cash flows and has a total of €49.7 million cash and cash equivalents balance at closing date. As of March 17, 2025, the Company signed an amendment to the Janssen Agreement (Refer to Note 25 – Subsequent events for further details), allowing to strengthen the Company’s financial position, to reduce its operational cash burn and to extend the Company’s cash runway into mid-2026. Following the signature of the amendment and based on the Company’s cash and cash equivalent balance at December 31, 2024, the Company projects that it has sufficient liquidity to meet its obligations as they become due in the normal course of business for at least the next 12 months from the authorization date of these financial statements. Accordingly, Management has determined there is no substantial doubt regarding the Company's ability to continue as a going concern.
Basis of consolidation | Accounting policy In accordance with IFRS 10 – Consolidated Financial Statements, the Group controls an entity when it is exposed or has rights to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Accordingly, each of the Company’s subsidiaries has been fully consolidated from the date on which the Company obtained control over it. A subsidiary would be deconsolidated as of the date on which the Company no longer exercises control. All intercompany balances, transactions, unrealized gains and losses resulting from intercompany transactions and all intercompany dividends are eliminated in full. The accounting methods of the Company’s subsidiaries are aligned with those of the Company. The consolidated financial statements are presented in euros, which is the presentation currency and the functional currency of the parent company, Nanobiotix S.A. The financial statements of consolidated foreign subsidiaries whose functional currency is not the euro are translated into euros for statement of financial position items at the closing exchange rate at the date of the statement of financial position and for the statement of operations, statement of comprehensive loss and statement of cash flow items at the average rate for the period presented, except where this method cannot be applied due to significant exchange rate fluctuations during the applicable period. The dollar to euro exchange rate used in the consolidated financial statements to convert the financial statements of the U.S. subsidiary was $1.0389 as of December 31, 2024 and an average of $1.0821 for the year ended December 31, 2024 (source: Banque de France) compared with $1.1050 and $1.0816 for 2023 and $1.0666 and $1.0539 for 2022, respectively. The resulting currency translation adjustments are recorded in other comprehensive income (loss) as a cumulative currency translation adjustment. Consolidated entities As of December 31, 2024, the Company is comprised of one parent entity, the consolidation scope has been reduced compared to that at December 31, 2023 as Nanobiotix S.A. has three wholly owned subsidiaries: •Nanobiotix Corp., incorporated in the State of Delaware in the United States in September 2014; •Nanobiotix Germany GmbH, incorporated in Germany in October 2017; •Nanobiotix Spain S.L.U., incorporated in Spain in December 2017; Curadigm SAS, an affiliate fully owned by Nanobiotix, has been merged into our main entity Nanobiotix SA from January 1, 2024. This merger is intended to rationalize the organization, accompany Nanobiotix strategy evolution and streamline operations. Curadigm Corp. which was a wholly-owned subsidiary of Curadigm S.A.S., incorporated in the State of Delaware on January 7, 2020 was liquidated May 22, 2024. As it was a dormant company with no employee, this dissolution has not any impact on the 2024 consolidated financial statements. The consolidated financial statements as of and for the year ended December 31, 2024 include the operations of each of these subsidiaries from the date of their incorporation.
Use of judgement, estimates and assumptions | 3.2. Use of judgement, estimates and assumptions The preparation of consolidated financial statements in accordance with IFRS requires the use of estimates and assumptions that affect the amounts and information disclosed in the financial statements. The estimates and judgments used by management are based on historical information and on other factors, including expectations about future events considered to be reasonable given the circumstances. These estimates may be revised where the circumstances on which they are based change. Consequently, actual results may vary significantly from these estimates under different assumptions or conditions. A sensitivity analysis may be presented if the results differ materially based on the application of different assumptions or conditions. The main items affected by the use of estimates are going concern, revenue recognition, share-based payments, deferred tax assets, clinical trials accruals and the measurement of financial instruments (fair value and amortized costs). Measurement of share-based payments The Company measures the fair value of stock options (OSA), founders’ warrants (BSPCE), warrants (BSA) and free shares (AGA) granted to employees, members of the Supervisory Board and consultants based on actuarial models. These actuarial models require that the Company use certain calculation assumptions with respect to characteristics of the grants (e.g., option vesting terms) and market data (e.g., to determine expected share volatility) (see Note 18 - Share-based payments). Deferred tax assets Deferred taxes are recognized for temporary differences arising from the difference between the tax basis and the accounting basis of the Company’s assets and liabilities that appear in its financial statements. The primary source of deferred tax assets are related to the tax losses that can be carried forward or backward, depending on the jurisdiction. Enacted or substantively enacted tax rates are used to measure deferred taxes. The deferred tax assets are recorded in the accounts only to the extent that it is probable that the future profits will be sufficient to absorb the losses that can be carried forward or backward. Considering its stage of development, which does not allow sufficiently reliable income projections to be made, the Company has not recognized deferred tax assets in relation to tax loss carryforwards in the statements of consolidated financial position. Clinical trial accruals Clinical trial expenses, although not yet billed in full, are estimated for each study and a provision accrual is recognized accordingly. See Note 14.1. - Trade and other payables for information regarding the clinical trial accruals as of December 31, 2024 and 2023. Going Concern Management assesses the Company's ability to continue as a going concern at each reporting date, using all quantitative and qualitative information available. This assessment, by its nature, relies on estimates of future cash flows and other future events whose subsequent changes could materially impact the validity of such an assessment. See Note 2 - General Information, Statement of Compliance and Basis of Presentation). Revenue recognition In order to determine the amount and timing of revenue under the contract with customers, the Company is required to use significant judgments, mainly with respect to identifying performance obligations of the Company, determining the stand alone selling price of the performance obligations, the transaction price allocation and the timing of satisfaction of support services provided to customers Determining the distinctiveness of performance obligations — A promised good or service will need to be recognized separately in revenue if it is distinct as defined in IFRS 15. In determining whether the performance obligation is separate, the Company analyses if (i) the good or service is distinct in absolute terms, i.e. it can be useful to the customer, either on its own or in combination with resources that the customer can obtain separately; and if (ii) the good or service is distinct in the context of the contract, i.e. it can be identified separately from the other goods and services in the contract because there is not a high degree of interdependence or integration between this element and the other goods or services promised in the contract. If either of these two conditions is not met, the good or service is not distinct, and the Company must group it with other promised goods or services until it becomes a distinct group of goods or services. Allocation of transaction price to performance obligations — A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. Variable consideration — Due to the nature of the work required to be performed on many of the Company’s performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. It is common for the collaboration and license agreements to contain variable consideration that can increase the transaction price. Variability in the transaction price arises primarily due to milestone payments obtained following the achievement of specific milestones (e.g., scientific results or regulatory or commercial approvals). The Company includes the related amounts in the estimated transaction price as soon as their receipt is highly probable. The effect of the increase of the transaction price due to milestones payments is recognized as an adjustment to revenue on a cumulative catch‑up basis. Revenue recognized over time and input method — Some of the Company’s performance obligations are satisfied over time as work progresses, thus revenue is recognized over time, using an input measure of progress as it best depicts the transfer of control to the customers. Contract modification — The Company accounts for a contract modification as if it were a part of the existing contract if the remaining goods or services are not distinct and, therefore, form part of a single performance obligation that is partially satisfied at the date of the contract modification. The effect that the contract modification has on the transaction price, and on the entity's measure of progress towards complete satisfaction of the performance obligation, is recognized as an adjustment to revenue at the date of the contract modification (i.e. on a cumulative catch-up basis). The Company is required to use significant judgments with respect to identifying and determining the amended stand alone selling price of the performance obligations, the transaction price allocation and the adjusted timing of satisfaction of the remaining services provided to customers. See Note 16. Revenues and other income for additional detail regarding the Company’s accounting policies and specific judgments taken with regards to revenue recognition, and for its additional sources of revenue and other income. Measurement of financial assets and liabilities At the renegotiation date in October 2022, the fair value measurement of the EIB loan required the Company to determine: –the discount rate of the new liability executed in October 2022. The discount rate reflects the company’s credit risk at the Amendment Agreement date as well as a premium to reflect uncertainties associated with the timing and the amount of the royalties’ payment. The Company involved external financial instruments valuation specialists to help determine the average discount rate; –the amount of additional interest (“royalties”, as defined by the royalty agreement with EIB) that will be due according to the loan agreement during a royalty calculation period commencing upon commercialization. The royalties due during this period will be determined and calculated based on the number of tranches that have been withdrawn and will be indexed to annual sales turnover relating to NBTXR3 through specific Company’s license agreement. For the purpose of measuring the fair value of the EIB loan, the Company forecast expected sales relating to NBTXR3 during the royalty period, taking into consideration operational assumptions such as market release dates of products and growth and penetration rates in each market. (see Note 4.4. - Financing Agreement with the European Investment Bank (“EIB”) and Note 13 - Financial Liabilities for details about this loan and the accounting treatment applied). Subsequent to the estimate of the fair value of the EIB loan performed at the renegotiation date, the debt has been measured at amortized cost based on a revised best estimate of future cash flows related to the debt at each closing date. Accordingly, the Company determines the amount of additional interest as described above. Any subsequent adjustment of flows indexed to turnover has been discounted at the original effective interest rate at the renegotiation date and the adjustment has been recognized in profit or loss under the “catch-up” method as of December 31, 2023. As of December 31, 2024, the fair value measurement of the EIB loan has been reassessed by the Company.
Intangible assets | Accounting policies In accordance with IAS 38 – Intangible Assets, intangible assets are carried at their acquisition cost. Research and Development costs Research costs are recorded in expenses in the period during which they are incurred. Under IAS 38 – Intangible Assets, development costs may only be capitalized as intangible assets if the following criteria are met: •it is technically feasible to complete the development of the intangible asset so that it will be available for use or sale; •the Company intends to complete the development of the intangible asset and use or sell it; •the Company has the ability to use or sell the intangible asset; •it is probable that the intangible asset will generate future economic benefits; •adequate technical, financial and other resources are available to complete the development of the intangible asset; and •the Company is able to reliably measure the expenditures attributable to the development of the intangible asset. The Company believes that because of the risks and uncertainties related to the grant of regulatory approval for the commercialization of its product candidates, the technical feasibility of completing its development projects will only be demonstrated when requisite approvals are obtained for the commercialization of products. Accordingly, pursuant to IAS 38, the Company has recognized all of its research and development costs incurred as an expense in 2024 and prior periods. Patents Costs incurred by the Company in connection with the filing of patent applications are recognized as an expense until such time as the relevant patents are obtained, in line with the treatment of research and development costs. Once the patents are obtained from relevant authorities, their related patent costs are amortized on a straight-line basis over the patent protection period. The useful life of the patents is reassessed each year, according to IAS 38. Software The costs of acquiring software licenses are recognized as assets on the basis of the costs incurred to acquire and implement the software to which the license relates. These costs are amortized on a straight-line basis over the life of the license. Recoverable amount of intangible assets Intangible assets with a definite useful life are tested for impairment when there are events or changes in circumstances that indicate that the asset might be impaired. Impairment tests involve comparing the carrying amount of an intangible asset with its recoverable amount. The recoverable amount of an asset is the higher of (i) its fair value less costs to sell and (ii) its value in use. If the recoverable amount of any asset is below its carrying amount, an impairment loss is recognized to reduce the carrying amount to the recoverable amount.
Property, plant and equipment | Accounting policies Property, plant and equipment are recorded at their acquisition cost. Major renovations and improvements necessary to bring an asset to the working condition for its use as intended by the Company’s management are capitalized. The cost of repairs, maintenance and other renovation work is expensed as incurred. Property, plant and equipment are depreciated on a straight-line basis according to the estimated useful life of the relevant assets. The depreciation periods used are as follows: •General fixtures and fittings, building work: 5 to 10 years; •Technical installations, equipment and industrial tooling: 3 to 10 years; and •Office and IT equipment and furniture: 1 to 10 years. Recoverable amount of property, plant and equipment Property, plant and equipment with a definite useful life are tested for impairment when there are events or changes in circumstances that indicate that the asset might be impaired. An impairment loss is recognized for the excess of the carrying amount of the asset over its recoverable amount. The recoverable amount of an asset is equal to the higher of (i) its fair value less costs to sell and (ii) its value in use.
Cash and cash equivalents | Accounting policy Cash equivalents are held for the purpose of meeting short-term cash commitments rather than for investment or other reasons. They are readily convertible into known amounts and are subject to an insignificant risk of value changes. Cash and cash equivalents consist of short-term highly liquid investments available immediately, and short-term deposits that were fully release in July 2024. Cash equivalents are measured at amortized cost.
Capital issued | Accounting policies Ordinary shares are classified in shareholders’ equity. The cost of equity transactions that are directly attributable to the issue of new shares or options is recognized in shareholders’ equity as a deduction from the proceeds of the issue.
Provisions | Accounting policies Provisions for contingencies and charges Provisions for contingencies and charges reflect obligations resulting from various disputes and risks for which due dates and amounts are uncertain, that the Company may face as part of its normal business activities. A provision is recognized when the Company has a present obligation (legal or constructive) as a result of a past event, where 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. The amount recorded in provisions is a best estimate of the outflow of resources that will be required to settle the obligation, discounted, if required, at year-end.
Accounting policies | Accounting policies Non-current financial assets Non-current financial assets are recognized and measured in accordance with IFRS 9 – Financial Instruments. No non-current financial assets are accounted for at fair value through other comprehensive income (OCI). Pursuant to IFRS 9 – Financial Instruments, financial assets are classified in three categories according to the Company’s business model for managing the financial asset and the contractual cash flows characteristics of the financial asset: •Financial assets at fair value through profit and loss; •Financial assets at fair value through other comprehensive income; and •Financial assets at amortized cost. All regular way purchases and sales of financial assets are recognized at the settlement date. Financial assets at fair value through profit or loss This category includes marketable securities. They represent financial assets held for trading purposes, i.e., assets acquired by the Company to be sold in the short-term. They are measured at fair value and changes in fair value are recognized in the consolidated statements of operations as financial income or expense, as applicable. As of December 31, 2024, the Company has no financial assets at far value through profit and loss. Financial assets at amortized cost This category includes other financial assets (non-current), trade receivables (current) and other receivables and related accounts (current) and cash and cash equivalents. Other financial assets (non-current) include advances and security and guarantee deposits granted to third parties as well as term deposits and restricted cash, which are not considered as cash equivalents. They are non-derivative financial assets with fixed or determinable payments that are not listed on an active market. They are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition or issue of the financial asset, except trade receivables that are initially recognized at the transaction price as defined in IFRS 15. After initial recognition, these financial assets are measured at amortized cost using the effective interest rate method when both of the following conditions are met: •The financial asset is held within a business model whose objective is to hold financial assets 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. Gains and losses are recorded in the consolidated statements of operations when they are derecognized, subject to modification of contractual or expected cash flows and/or impaired. IFRS 9 – Financial Instruments requires an entity to recognize a loss allowance for expected credit losses on a financial asset at amortized cost at each Statement of Financial Position date. The amount of the loss allowance for expected credit losses equals: (i) the 12 - month expected credit losses or (ii) the full lifetime expected credit losses. The latter applies if credit risk has increased significantly since initial recognition of the financial instrument. An impairment is recognized, where applicable, on a case–by–case basis to take into account collection difficulties which are likely to occur based on information available at the time of preparation of the financial statements. Disputed receivables are written-off when certain and precise evidence shows that recovery is impossible and existing credit loss allowance are released. Financial liabilities The Company receives assistance in the form of grants, conditional advances and interest-free loans. Under IFRS, a repayable advance that does not require the payment of annual interest is considered to be an interest-free loan. The difference between the amount of the advance at historical cost and the advance discounted at the Company's average borrowing rate is considered to be a government grant. These grants are deferred over the estimated duration of the projects they finance. The long-term (more than one year) portion of conditional advances is recognized in non-current financial liabilities and the short-term portion in current financial liabilities. Non-repayable conditional loans are treated as government grants when there is reasonable assurance that the Company will comply with the conditions for non-repayment. Otherwise, they are classified in liabilities. Government grants made available to offset expenses or losses already incurred, or as immediate financial assistance to the Company with no future related costs, are recognized in income in the period in which the grant is allocated. Financial liabilities are recognized and measured in accordance with IFRS 9 – Financial Instruments. Financial liabilities, including trade and other payables are valued at amortized cost. Financial liabilities at amortized cost Loans and other financial liabilities are recognized and measured in accordance with IFRS 9 – Financial Instruments. They are recognized at amortized cost, which is defined under IFRS 9 as the amount at which the financial asset or financial liability is measured at initial recognition minus the principal repayments, plus or minus the cumulative amortization using the effective interest method of any difference between that initial amount and the maturity amount and, for financial assets, adjusted for any loss allowance. Transaction costs directly attributable to the acquisition or issuance of financial liabilities are deducted from the financial liabilities. The costs are then amortized on an actuarial basis over the life of the liability using the effective interest rate, namely the rate that exactly discounts estimated future cash flows to the net carrying amount of the financial liability in order to determine its amortized cost.
Revenue and other income | Accounting policies Revenue and other income Revenue is recognized in accordance with IFRS 15. Under IFRS 15, revenue is recognized when the Company satisfies a performance obligation by transferring a distinct good or service (or a distinct bundle of goods and/or services) to a customer, i.e. when the customer obtains control of these goods or services. Given the wide spectrum of therapeutic research and development opportunities, aside from the fields that the Company intends to research and develop with its own scientific and financial resources, the Company has entered and expects to enter into new license and collaboration agreements with third parties in certain specific fields that have generated or may generate future revenue. Therefore, each agreement has been and will be analyzed, on a case-by-case basis to determine whether the arrangement contains performance obligations to the other party and, if so, to identify the nature of these performance obligations in order to determine the appropriate accounting under IFRS 15 principles of the amounts that the Company has received or is entitled to receive from the other party, e.g.: •Development services performed by the Company to create or enhance an intellectual property controlled by the client, for which revenue is recognized over time, when services are rendered; •A transfer of control of an existing intellectual property of the Company for which revenue is recognized at the time such control is transferred; •A license: ◦If the license is assessed to be a right to access the Company’s intellectual property as it exists throughout the license period, revenue is recognized over the license period; or ◦If the license is a right to use the Company’s intellectual property as it exists (in term of forms and functionality), revenue is recognized when the other party is able to use and benefit from the license; or •Product supply for which the revenue is recognized once the control over the delivered products is transferred. Contingent revenue arising from successful milestones are included in the estimated transaction price when it becomes highly probable that the resulting revenue recognized would not have to be reversed in a future period. Sales-based milestones or royalties are not recognized before the related milestone has been reached or sale has occurred. Application of IFRS 15 to the Janssen Agreement In July 2023, the Company entered into the Janssen Agreement, granting Janssen an exclusive worldwide license for the development, the manufacturing and the commercialization of NBTXR3. The license is exclusive, except for territories previously licensed to the Company initial licensee LianBio (see below). Unless terminated earlier, the Janssen Agreement will remain in effect for so long as royalties are payable under the Janssen Agreement. The Janssen Agreement may be terminated earlier by either party in the event that the other party commits an uncured material breach, or in the case of certain insolvency or bankruptcy events. Additionally, Janssen has the right to terminate the agreement without cause, provided they give prior written notice to the Company. The Company is responsible for on all ongoing studies, along with NBTXR3 manufacturing, clinical supply, and initial commercial supply, subject to Janssen’ right to object based on concern regarding safety risks or that the study is reasonably likely to adversely affect the development (including commercialization) of the licensed product. Janssen will be fully responsible for an initial Phase 2 study evaluating NBTXR3 for patients with stage three lung cancer. Additionally, as per the license agreement, Janssen may request that Nanobiotix transfer and assign the regulatory documentation and sponsorship for ongoing studies (including NANORAY-312 trial) to Janssen. Subsequently, further to the agreements signed in October 2024 regarding the transfer of the global sponsorship of NANORAY-312 study (see below), Janssen will become sponsor on a country by country basis upon acceptance by local or applicable regulatory authorities and the Company will continue to conduct the execution of the on-going studies in accordance with established protocols. Following the HSR antitrust clearance, the Company received in 2023 an upfront cash licensing fee of $30 million. The Company is eligible for success-based payments of up to $1.8 billion, in the aggregate, relating to potential development, regulatory, and sales milestones. Moreover, the agreement includes a framework for additional success-based potential development and regulatory milestone payments of up to $650 million, in the aggregate, for five new indications that may be developed by Janssen at its sole discretion; and of up to $220 million, in the aggregate, per indication that may be developed by the Company in alignment with Janssen. Following commercialization, the Company will also be eligible tiered double-digit royalties (low 10s to low 20s) on net sales of NBTXR3. Revenue is recognized under IFRS 15 – Revenue from contracts with customers (see Note 3.2. – Us e of judgement, estimates and assumptions). The Janssen Agreement, being a license to develop, manufacture, commercialize a product candidate, and ongoing development services, is within the scope of IFRS 15, as it is an output of the Company’s ordinary activities. Following the IFRS 15 analysis, two main distinct performance obligations under the Janssen Agreement have been identified: •License Grant: transfer of all data and information that is useful for the development, manufacture or commercialization of the licensed compound (NBTXR3) worldwide, excluding the Asia Licensing Territory. The license grant corresponds to a right-to-use license and the transfer of this license has been completed by December 31, 2023. Revenue is recognized point in time accordingly in 2023 (see below); and •Ongoing Nanobiotix-conducted studies: the Company is committed to perform the head and neck (“H&N”) study and other ongoing Nanobiotix-conducted studies. These studies will benefit to Janssen (who holds the license) and therefore represent a service promised to the customer. In the course of the ongoing Nanobiotix-conducted studies, the Company provides development services in connection with the license, which is controlled by Janssen since the date of its transfer, until the end of the studies. Based on the Company’s assessment of the nature of the services, the ongoing Nanobiotix-conducted studies were determined to be a separate performance obligation as the promise is separately identifiable as part of the contract and Janssen can benefit from the services with the license that has already been transferred. Janssen has access to the development progress over time and revenue is recognized overtime accordingly (see below). Under the Janssen Agreement, Janssen is committed to make the following payments: •Upfront payment: Non-refundable upfront fee for $30 million, due within 10 days after the contract execution date as defined in the contract.; •Success-based milestones: Success-based development, regulatory and commercial milestones for up to $1.8 billion in the aggregate; •Royalties: Sales-based royalties. In addition to the above, the Janssen Agreement includes several additional success-based potential development and regulatory milestone payments: •up to $650 million, in the aggregate, for five potential new indications that may be developed by Janssen at its sole discretion; and •up to $220 million, in the aggregate, per indication that may be developed by the Company in alignment with Janssen. Thus, the consideration for Janssen Agreement consists of fixed and variable parts. As of December 31, 2023, the Company estimated the constrained transaction price for $50 million, which includes: •The $30 million upfront payment, allocated among each performance obligation based on their respective standalone selling prices. •Regulatory and development milestones payments whose payment depends on the achievement of certain technical or regulatory events, as provided in the contract. Variable considerations are included in the estimated transaction price if and when, it becomes highly probable that the resulting revenue recognized would not have to be reversed in a future period. Subsequently, as of December 31, 2023, the Company was entitled to receive a $20 million milestone with no refund risk; had Janssen terminated the contract on January 1, 2024, the Company would still have been entitled the $20 million conditional payment, included in the estimated transaction price due to the high probability of achieving the first milestone as of December 31, 2023. •Estimated variable considerations for commercial milestones are included in the estimated transaction price only when the cumulative threshold specified in the contract has been reached, starting upon the potential commercialization of the licensed products. Sales-based royalties’ revenue are included in the estimated transaction price at the later of (i) when the subsequent sale occurs or (ii) when the performance obligation has been satisfied. Subsequently, no variable consideration relating to commercial milestones or royalties was included in the estimated transaction price as of December 31, 2023 or as of December 31, 2024. In order to allocate the estimated transaction price to the performance obligations, the Company determined that : •Commercial milestones and royalties should be allocated directly to the license grant, in accordance with IFRS 15.85. •Remaining payments (i.e. upfront payment and R&D milestones related to ongoing Nanobiotix-conducted studies) should be allocated to each performance obligation. The allocation of the remaining payments to each performance obligation has been performed by determining the stand-alone selling price of the ongoing Nanobiotix-conducted studies on cost plus margin basis and the allocation to the license was determined on the residual method. Revenue is recognized at a point in time or overtime depending on the allocation to each performance obligation. Revenue is recognized at a point in time for the existing know-how transferred to Janssen and overtime for the percentage completed (input method) of the ongoing Nanobiotix-conducted studies. The Janssen Agreement provides a distinct right-to-use license; therefore under IFRS 15, the fixed part of the consideration is included in the estimated transaction price as soon as the licensee can direct the use and benefit from the license. Royalties on commercial sales and commercial milestones, if any, will be recognized as revenue when the underlying sales will be made, under the terms and timeframes set out in the agreement. No amount was recognized in either 2023 or 2024. Separately, the Company received approximatively $30 million in equity investments from JJDC, comprising an initial tranche of $5 million issued without preferential subscription rights which was received as of September 13, 2023; and a second tranche of $25 million received as follows: $20.2 million received on November 7, 2023, and $4.8 million received on December 4, 2023 (see Note 10 – S hare Capital). Regarding the first tranche, the Company determined that a reallocation of consideration between revenue contract and equity contract was not necessary as there was no significant difference between the fair value of the shares and the subscription price at the date of contract. In addition, regarding the second tranche, as the subscription price was equal to the market price in the framework of the Global Offering (see Note 10 – Share Capital), which is the fair value of the shares, no reallocation was made. The Company announced in May 2024 its intent, aligned with Janssen, to transfer the global sponsorship of the ongoing NANORAY-312 Phase 3 pivotal trial in head and neck cancer to Janssen, in preparation for potential regulatory submission in the event of positive trial results. The parties mutually agreed on the conditions of this transfer and detailed them in agreements signed in the fourth quarter of 2024. Janssen will progressively take over from the Company the operational conduct and execution responsibility of the study, on a country by country basis, starting November 2024, with the objective to complete the transfer of sponsorship in the short term, while the Company remains liable for the overall costs of the study towards Janssen. The Company will continue to support Janssen in execution of NANORAY-312 clinical study during the transition process and following the sponsorship transfer. The Company signed a new amendment to this contract after the end of the reporting period. The details of this amendment are presented in the Note 25 - Subsequent Events. These agreements aim to transfer rights and obligations of the Company to Janssen at the date of the sponsorship transfer in each country. The impact on the performance obligations are the following: •License grant: no impact, •Ongoing Nanobiotix-conducted studies: decrease in the scope of development services that were initially to be provided by the Company to Janssen, as Janssen will take over progressively those activities and direct responsibilities for conducting the studies. As at December 31, 2024, the Company still had a funding obligation towards Janssen as the Company remains liable for the overall costs of the clinical study NANORAY-312 further to the Janssen Agreement. These agreements have been considered and accounted for as a contract modification under IFRS 15, which amends the Janssen Agreement by decreasing significantly the transaction price due to the replacement of the R&D performance obligation by a pure funding obligation for the Company to reimburse Janssen for all the remaining costs of the NANORAY-312 clinical study, slightly offset by a transaction price increasing as the Company has to rebill certain transition R&D activities to Janssen. The net negative impact in the transaction price was accounted for as a cumulative catch-up impact, as the remaining goods or services are not distinct. Revenue for the the year ended December 31, 2024 therefore included a negative one-off impact of €23.4 million, directly due to the contract modification as explained above, leading to a total cumulated negative €19.3 million net revenue impact over the year 2024. Still in accordance with IFRS 15, the funding obligation towards Janssen resulted in a net refund liability recognition amounting to €35.6 million. See Note 14.4. - Refund liabilities An amendment of the Janssen Agreement has been signed on March 17, 2025 with Janssen (See Note 25 - Subsequent Events). The amendment provides that Janssen will finally assume nearly all remaining costs for the ongoing pivotal Phase 3 trial through completion, less a limited portion of costs remaining covered by the Company. The Company is currently assessing the expected impacts of the amendment on the consolidated financial statements (including on revenue and refund liability) for the period starting January 1, 2025. Application of IFRS rules to the Asia Licensing Agreement In May 2021, the Company executed the Asia Licensing Agreement, pursuant to which LianBio received an exclusive right to develop and commercialize NBTXR3 in China and other east Asian countries. Under the Asia Licensing Agreement, the Company remains responsible for the manufacturing of the licensed products. The Company is not required to transfer manufacturing know-how, unless the Company, at any time following a change of control of the Company, fails to provide at least 80% of LianBio's requirements for licensed products in a given calendar year. Pursuant to the Asia Licensing Agreement, the parties will collaborate on the development of NBTRX3 and LianBio will participate in global Phase 3 registrational studies, for several indications, by enrolling patients in China. The Company received in June 2021 a non-refundable upfront payment of $20 million from LianBio. In addition, the Company may receive up to $205 million in potential additional payments upon the achievement of certain development and sales milestones, as well as tiered, low double-digit royalties based on net sales of NBTXR3 in the licensed territories thereunder. The Company is also entitled to receive payments for development and commercial vials ordered by LianBio and supplied by the Company. The license to commercialize a product candidate, ongoing transfer of unspecified know-how related to development and commercialization and the supply services (for commercial products) are in the scope of IFRS 15, as they are an output of the Company’s ordinary activities. For IFRS 15 purpose, it was determined that the license is not distinct from the commercial manufacturing services because the customer cannot benefit from the license without the manufacturing services and such services are not available from third party-contract manufacturers. Accordingly, the license and commercial manufacturing services are treated as one single performance obligation which is recognized as manufacturing services are performed. Milestone payments linked to regulatory marketing approvals will be included in the transaction price only when and if the contingency is resolved and will be recognized as revenue when manufacturing services are provided. Sales-based milestone payments will be recognized when the sales thresholds are achieved. Royalties will be recognized when the underlying sales are made by LianBio. The $20 million upfront payment received from LianBio in June 2021 has been recognized as a Contract Liability and will be recognized as revenue over the term of the arrangement, as manufacturing services (for commercial products) are provided. The mutualization of development efforts leading to the regulatory marketing approvals are treated as a collaboration arrangement outside of the scope of IFRS 15. If any R&D cost incurred is eligible for partial reimbursement by Lianbio, the corresponding recharge is recognized as Other Income. This includes the supply of products necessary to conduct the clinical trials, R&D cost incurred that is eligible for partial reimbursement by Lianbio, that are recognized as Other Income. The related income is recognized respectively when the products are delivered to LianBio and when the eligible costs are incurred by LianBio. Milestone payments linked to regulatory marketing approvals will be included in the transaction price only when and if the contingency is resolved and will be recognized to revenue as manufacturing services are provided. Sales-based milestone payments will be recognized when the sales thresholds are achieved. Royalties will be recognized when the underlying sales are made by LianBio. On May 9, 2022, the Company signed the clinical supply agreement with LianBio as defined in the license, development, and commercialization agreement. This agreement provides for the supply by the Company to LianBio of vials of NBTXR3 and Cetuximab products for clinical trial development activities. For the year ended December 31, 2023, the Company billed the delivery of NBTXR3 and other clinical supplies to LianBio amounting to €334.3 thousand, recorded within Other Income as it relates to the non-IFRS 15 components of the agreement (the development collaboration). Subsequent to the novation agreement (see below), the Company billed the delivery of NBTXR3 and other clinical supplies to Janssen amounting to €237 thousand, for the year ended December 31, 2024 in connection with the supply agreement. On June 30, 2023, the Company signed a Global Trial Clinical Agreement (“GTCA”) with LianBio in connection with the Asia Licensing Agreement signed on May 11, 2021. As contemplated by the Asia Licensing Agreement, LianBio shall participate in the global registrational Phase 3 trial “HNSCC 312” conducted by Nanobiotix, with regard to NANORAY-312 trials conducted within the licensed territories thereunder. According to the ‘GTCA’, LianBio is responsible for all internal and external costs incurred in connection with the study in the licensee territories as well as all external costs and expenses incurred by or on behalf of the Company for the global study. In this context, for the year ended December 31, 2023, the Company billed the costs to LianBio for an amount of €1.6 million, recorded within Other Income as it relates to the non-IFRS 15 components of the agreement (the development collaboration). Subsequent to the novation agreement (see below), the Company billed the costs to Janssen amounting to €778 thousand, for the year ended December 31, 2024 in connection with the GTCA. On December 22, 2023, the Company, LianBio and Janssen executed a novation agreement whereas all the rights and obligations of Asia Licensing Agreement, dated May 11, 2021, between the Company and LianBio, as well as other related agreements, were assigned from LianBio to Janssen. Whereas the Company analyzed that the rights and obligations of the original License Agreement were transferred without any alteration or modification, the Company concluded that as a result of the novation agreement, the original contract with LianBio was terminated while a new contract was entered onto with Janssen. As a result, the Company derecognized the original contract liability to LianBio, corresponding to the $20 million upfront payment received in 2021, and recognized a new contract liability to Janssen at its fair value, resulting in a loss of €1.6 million as of December 31, 2023 (See Note 4.1. - New Global License Agreement, Note 4.2. - Asia Licensing Agreement, Note 14 - Trade and other payables, and Note 17.5. - Other operating income and expenses). The Company determined that the new contract meets the definition of a separate contract, in accordance with IFRS 15.20 and on the other hand does not meet the definition of a contract modification as defined by IFRS 15.18 as the novation agreement resulted from a pre-existing contractual right of LianBio which did not require the approval of the Company. Consequently the contract modification model should not be applied. The Company determined as, in the LianBio contract, the license and manufacturing services are not distinct and represent a single performance obligation. Consequently, the whole amount of the contract liability should be replaced with the fair value of the contract liability of the new contract (see above) and no amount should be released to revenue. Grants Due to its innovative approach to nanomedicine, the Company has received various grants and other assistance from the government of France and French public authorities since its creation. The funds are intended to finance its operations or specific recruitments. Grants received are recognized by the Company in the financial statements when there is reasonable assurance that the Company will comply with the conditions attached to the subsidies and that the subsidies will be received, independently of cash flows received. A government grant receivable either as compensation for expenses or losses already incurred or as immediate financial support to the Company with no future related costs is recognized as income in the period in which it becomes receivable. A grant is recognized in the income statement based on the actual progress of the projects for which it is awarded. More specifically, the grant is recognized as deferred income and reported in the income statement based on project progress, which is assessed by taking into account, firstly, the time spent by employees and, secondly, subcontracting expenses allocated to the projects and covered by the grant. Research tax credit The French tax authorities grant a research tax credit (Crédit d’Impôt Recherche, or “CIR”), to companies in order to encourage them to conduct technical and scientific research. Companies demonstrating that they have incurred research expenditures that meet the required criteria (research expenses in France or, since January 1, 2005, other countries in the European Community or the European Economic Area that have signed a tax treaty with France containing an administrative assistance clause) receive a tax credit that can theoretically be compensated with the income tax due on the profits of the financial year during which the expenses have been incurred and the following three years. Any unused portion of the credit is then refunded by the French Treasury. If the Company can be qualified as small and medium-sized enterprises, in France the “PME”, it can request immediate refund of the remaining tax credit, without application of the three-year period). The Company has received research tax credits since its creation. These amounts are recognized as "Other income" in the fiscal year in which the corresponding charges or expenses were incurred. In case of capitalization of research and development expenses, the portion of research tax credit related to capitalized expenses is deducted from the amount of capitalized expenses on the statements of financial position and from the amortization charges for these expenses on the statements of operations.
Operating expenses | Accounting policies Leases included in the practical expedients under the IFRS 16 standard and used by the Company (low value asset and short-term leases) are recognized in operating expenses. Payments made for these leases are expensed, net of any incentives, on a straight-line basis over the contract term (see Note 23 - Commitments).
Income tax | Accounting policy The Company and its subsidiaries are subject to income tax in their respective jurisdictions. Deferred taxes are recognized when there are temporary differences between the carrying amount of assets and liabilities in the Company’s financial statements and the corresponding tax base used to calculate taxable profit. Deferred taxes are not recognized if they arise from the initial recognition of an asset or liability in a transaction other than a business combination which, at the time of the transaction, does not affect either the accounting or the taxable profit (tax loss). The main source of deferred taxes relate to unused tax loss carryforwards. Deferred taxes are measured at the tax rates that are expected to apply to the period when the asset is expected to be realized or the liability is expected to be settled, based on tax rates and tax laws enacted or substantively enacted by the end of the reporting period. Deferred tax assets, which mainly arise as a result of tax loss carryforwards, are only recognized to the extent that it is probable that sufficient taxable income will be available in the future against which to offset the tax loss carryforwards or the temporary differences. The recoverable amount of deferred tax assets is reviewed at the end of each reporting period and their carrying amount is reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of the deferred tax assets to be utilized. Unrecognized deferred tax assets are reassessed at the end of each reporting period and are recognized when it becomes probable that future taxable profit will be available to offset the temporary differences. Management uses its best judgment to determine such probability. Given the Company’s current stage of development and its short-term earnings outlook, no deferred tax assets have not been recognized;
Segment reporting | In accordance with IFRS 8 – Operating Segments, reporting by operating segment is derived from the internal organization of the Company’s activities; it reflects management’s viewpoint and is established based on internal reporting used by the chief operating decision maker (the Company’s Chief Executive Officer and Chairmen of the Executive Board and of the Supervisory Board) to allocate resources and to assess performance. The Company operates in a single operating segment: research and development in product candidates that harness principles of physics to transform cancer treatment. The negative net revenue, as disclosed in the ‘Note 16 - Revenue and other Income’, is primarily recognized by the Company towards one principal customer, Janssen BV, located in Belgium. The assets, liabilities and operating loss realized are primarily located in France.
Loss per share | Accounting policy Loss per share is calculated by dividing the net loss due to shareholders of the Company by the weighted average number of ordinary shares outstanding during the period. The diluted loss per share is calculated by dividing the results by the weighted average number of common shares in circulation, increased by all dilutive potential common shares. The dilutive potential common shares include, in particular, the share subscription warrants, stock options, free shares, founder subscription warrants as detailed in Note 10 and 18. Dilution is defined as a reduction of earnings per share or an increase of loss per share. When the exercise of outstanding share options and warrants decreases loss per share, they are considered to be anti-dilutive and excluded from the calculation of loss per share.
Subsequent events | Accounting policy The statements of consolidated financial position and statements of consolidated operations are adjusted for post-closing events until the date of authorization for issuance of the financial statements as long as they have a significant impact on the amounts presented at the closing date of the statement of financial position. If they do not, they are disclosed in the Note 25 - Subsequent Event. Adjustments and disclosures are made up to the date on which the consolidated financial statements are approved and authorized for issuance by the Supervisory Board.
