Unaudited Notes to the Interim Condensed Consolidated Financial Statements

for the three-month period ended March 31, 2024

(Amounts in Swiss francs)

1. General information

Addex Therapeutics Ltd (the "Company"), formerly Addex Pharmaceuticals Ltd, and its subsidiaries (together, the "Group") are a clinical stage biopharmaceutical company focused on developing a portfolio of novel small molecule allosteric modulators for neurological disorders.

The Company is a Swiss stockholding corporation domiciled c/o Addex Pharma SA, Chemin des Aulx 12, CH 1228 Plan-les-Ouates, Geneva, Switzerland and the parent company of Addex Pharma SA, Addex Pharmaceuticals France SAS, Neurosterix Pharma Sàrl, Neurosterix SA and Addex Pharmaceuticals Inc. The Groups principal place of business is Chemin des Mines 9, CH 1202 Geneva, Switzerland. Its registered shares are traded at the SIX Swiss Exchange, under the ticker symbol ADXN. On January 29, 2020, the Group listed on the Nasdaq Stock Market, American Depositary Shares (ADSs) under the symbol "ADXN", without a new issuance of securities. ADSs represents shares that continue to be admitted to trading on SIX Swiss Exchange.

These interim condensed consolidated financial statements have been approved for issuance by the Board of Directors on June 5, 2024.

2. Basis of preparation

These interim condensed consolidated financial statements for the three-month period ended March 31, 2024, have been prepared under the historic cost convention and in accordance with IAS 34 "Interim Financial Reporting" and are presented in a format consistent with the consolidated financial statements under IAS 1 "Presentation of Financial Statements". However, they do not include all of the notes that would be required in a complete set of financial statements. Thus, this interim financial report should be read in conjunction with the consolidated financial statements for the year ended December 31, 2023.

Interim financial results are not necessarily indicative of results anticipated for the full year. The preparation of these unaudited interim condensed consolidated financial statements made in accordance with IAS 34 requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although these estimates are based on management's best knowledge of current events and actions, actual results ultimately may differ from those estimates. The areas involving a higher degree of judgment which are significant to the interim condensed consolidated financial statements are disclosed in note 4 to the consolidated financial statements for the year ended December 31, 2023.

A number of new or amended standards and interpretations became applicable for financial reporting periods beginning on or after January 1, 2024. Of the latter, the Group noted the publication of IFRS S1 (General requirement for disclosure of sustainability-related financial information) and IFRS S2 (climate - related Disclosures). The Group concluded that those new IFRS standards were not relevant as the Group did not opt for the publication of a sustainability report in accordance with Six Swiss Exchange listing rules.

There are other new standards, amendments and interpretations which have been deemed by the Group as currently not relevant, hence are not listed or discussed further here.

Due to rounding, numbers presented throughout these interim condensed consolidated financial statements may not add up precisely to the totals provided. All ratios and variances are calculated using the underlying amounts rather than the presented rounded amounts.

Where necessary, comparative figures have been revised to conform with the current year 2024 presentation. In particular, we re-presented the unaudited interim condensed consolidated statements of comprehensive loss of the first quarter of 2023, in order to reclass discontinued operations in accordance with IFRS 5 (note 20). In addition, the ADS numbers previously disclosed have been amended following the change in ADS ratio executed on October 23, 2023, from one ADS to six shares to a new ratio of one ADS to one hundred and twenty shares. The ADS ratio change had the same effect as a one to twenty ADS reverse split and except as otherwise indicated, all information in these consolidated financial statements gives retroactive effect to the ADS Ratio Change.

3. Material accounting estimates and judgments

The Group makes estimates and assumptions concerning the future. These estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities or may have had a significant impact on the reported results are disclosed below:

Going concern

The Group's accounts are prepared on a going concern basis. To date, the Group has financed its cash requirements primarily from share issuances, licensing certain of its research and development stage products and selling its allosteric modulator drug discovery technology platform and a portfolio of preclinical programs. The Group is a development - stage enterprise and is exposed to all the risks inherent in establishing a business. The Group expects that its existing cash and cash equivalents, at the issuance date of these unaudited consolidated financial statements will be sufficient to fund its operations and meet all of its obligations as they fall due, through 2026. The future viability of the Group is dependent on its ability to raise additional capital through public or private financings or collaboration agreements to finance its future operations, which may be delayed due to reasons outside of the Group's control including health pandemics and geopolitical risks. The sale of additional equity may dilute existing shareholders. The inability to obtain funding, as and when needed, would have a negative impact on the Group's financial condition and ability to pursue its business strategies. If the Group is unable to obtain the required funding to run its operations and to develop and commercialize its product candidates, the Group could be forced to delay, reduce or stop some or all of its research and development programs to ensure it remains solvent. Management continues to explore options to obtain additional funding, including through collaborations with third parties related to the future potential development and/or commercialization of its product candidates. However, there is no assurance that the Group will be successful in raising funds, closing collaboration agreements, obtaining sufficient funding on terms acceptable to the Group, or if at all, which could have a material adverse effect on the Group's business, results of operations and financial condition.

The Business of the Group could be adversely affected by health pandemics and geopolitical risks

The business of the Group could be adversely affected by health epidemics and geopolitical risks in regions where the Group or partners have concentrations of clinical trial sites or other business operations and could cause significant disruption in the operations of third-party manufacturers and CROs upon whom the Group or partners rely. Health pandemics may pose the risk that the Group, employees, contractors, collaborators, and partners may be prevented from conducting certain pre-clinical tests, clinical trials or other business activities for an indefinite period of time, including due to travel restrictions, quarantines, "stay-at-home" and "shelter-in-place" orders or shutdowns that have been or may in the future be requested or mandated by governmental authorities. For example, the COVID-19 pandemic has impacted and could in the future impact the business of the Group and ongoing and planning clinical trials led by the Group or partners, including as a result of delays or difficulties in clinical site initiation, difficulties in recruiting and retaining clinical site investigators and clinical site staff and interruption of the clinical supply chain or key clinical trial activities, such as clinical trial site monitoring, and supply chain interruptions caused by restrictions for the supply of materials for drug candidates or other materials necessary to manufacture product to conduct clinical and preclinical tests. Geopolitical risks such as Russia-Ukraine war or Middle East conflict may create global security concerns including the possibility of an expanded regional or global conflict and potential ramifications such as disruption of the supply chain including research and development activities being conducted by the Group and its strategic partners. The Group and partners rely on global networks of contract research organizations to engage clinical study sites and enroll patients, certain of which are in Russia and Ukraine. Delays in research and development activities of the Group and its partners could increase associated costs and, depending upon the duration of any delays, require the Group and its partners to find alternative suppliers at additional expense. In addition, Russia-Ukraine war has had significant ramifications on global financial markets, which may adversely impact the ability of the Group to raise capital on favorable terms or at all.

Discontinued operations, assets and liabilities held for sale related to the Neurosterix Transaction

During the first quarter of 2024, it became highly probable that the Group would sell a part of its business constituted by its allosteric modulator drug discovery technology platform and a portfolio of preclinical programs (see note 20). As a consequence, the group recorded assets held for sale, liabilities held for sale as of March 31, 2024 and recognized discontinued operations in the financial line of the statements of comprehensive loss called "net loss from discontinued operations" for the three month-period ended March 31, 2024 and 2023 respectively, in accordance with IFRS 5. The Group identified cash flows from discontinued operations for the three month-period ended March 31, 2024 and 2023, respectively (see note 20). The identification of assets held for sale, liabilities held for sale and discontinued operations may require some degree of judgement.

Addex Therapeutics │ Unaudited Interim Condensed Consolidated Financial Statements │Notes

Revenue recognition

Revenue is primarily from fees related to licenses, milestones and research services. Given the complexity of the relevant agreements, judgements are required to identify distinct performance obligations, allocate the transaction price to these performance obligations and determine when the performance obligations are met. In particular, the Group's judgement over the estimated stand-alone selling price which is used to allocate the transaction price to the performance obligations is disclosed in note 15.

Grants

Grants are recorded at their fair value when there is reasonable assurance that they will be received and recognized as income when the Group has satisfied the underlying grant conditions. In certain circumstances, grant income may be recognized before explicit grantor acknowledgement that the conditions have been met.

Accrued research and development costs

The Group records accrued expenses for estimated costs of research and development activities conducted by third party service providers. The Group records accrued expenses for estimated costs of research and development activities based upon the estimated amount of services provided, but not yet invoiced, and these costs are included in accrued expenses on the balance sheets and within research and development expenses in the statements of comprehensive loss. These costs are a significant component of research and development expenses. Accrued expenses for these costs are recorded based on the estimated amount of work completed in accordance with agreements established with these third parties. Due to the nature of estimates, the Group may be required to make changes to the estimates after a reporting period as it becomes aware of additional information about the status or conduct of its research activities.

Research and development costs

The Group recognizes expenditure incurred in carrying out its research and development activities, including development supplies, until it becomes probable that future economic benefits will flow to the Group, which results in recognizing such costs as intangible assets, involving a certain degree of judgement. Currently, such development supplies are associated with preclinical and clinical trials of specific products that have not demonstrated technical feasibility.

Share-based compensation

The Group recognizes an expense for share-based compensation based on the valuation of equity incentive units using the Black-Scholes valuation model. A number of assumptions related to the volatility of the underlying shares and to the risk-free rate are made in this model. Should the assumptions and estimates underlying the fair value of these instruments vary significantly from management's estimates, then the share-based compensation expense would be materially different from the amounts recognized.

Equity instruments

The group records in equity the prefunded warrants sold to investors and the warrants granted to investors at a fair value whose valuation is calculated using Black - Scholes model.

Pension obligations

The present value of the pension obligations is calculated by an independent actuary and depends on a number of assumptions that are determined on an actuarial basis such as discount rates, future salary and pension increases, and mortality rates. Any changes in these assumptions will impact the carrying amount of pension obligations. The Group determines the appropriate discount rate at the end of each period. This is the interest rate that should be used to determine the present value of estimated future cash outflows expected to be required to settle the pension obligations. In determining the appropriate discount rate, the Group considers the interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating the terms of the related pension liability. Other key assumptions for pension obligations are based in part on current market conditions.

4. Interim measurement note

Seasonality of the business:The business is not subject to any seasonality, but expenses and corresponding revenue are largely determined by the phase of the respective projects, particularly with regard to external research and development expenditures.

Costs: Costs that incur unevenly during the financial year are anticipated or deferred in the interim report only if it would also be appropriate to anticipate or defer such costs at the end of the financial year.

Prepayments			651,567				217,008
Total other current assets			878,994				369,124

Prepayments increased by CHF 0.5 million as of March 31, 2024 compared to December 31, 2023 primarily due to retirement benefits paid annually at the beginning of the year. Prepayments related to retirement benefits of employees transferred to Neurosterix on April 2, 2024 are not considered as an asset held for sale. The Group applies the IFRS 9 simplified approach to measuring expected credit losses ("ECL"), which uses a lifetime expected loss allowance for all contract assets, trade receivables and other receivables. The Group has considered that the contract asset, trade receivables and other receivables have a low risk of default based on historic loss rates and forward-looking information on macroeconomic factors affecting the ability of the third parties to settle invoices. As a result, expected loss allowance has been deemed as nil as of March 31, 2024 and December 31, 2023.

15. Revenue from contract with customer

License & research agreement with Indivior PLC

On January 2, 2018, the Group entered into an agreement with Indivior for the discovery, development and commercialization of novel GABAB PAM compounds for the treatment of addiction and other CNS diseases. This agreement included the selected clinical candidate, ADX71441. In addition, Indivior agreed to fund a research program at the Group to discover novel GABAB PAM compounds.

The contract contains two distinct material promises and performance obligations: (1) the selected compound ADX71441 which falls within the definition of a licensed compound, whose rights of use and benefits thereon was transferred in January 2018 and, (2) the research services to be conducted by the Group and funded by Indivior to discover novel GABAB PAM compounds for clinical development that may be discovered over the research term of the agreement and selected by Indivior.

Indivior has sole responsibility, including funding liability, for development of selected compounds under the agreement through preclinical and clinical trials, as well as registration procedures and commercialization, if any, worldwide. Indivior has the right to design development programs for selected compounds under the agreement. Through the Group's participation in a joint development committee, the Group reviews, in an advisory capacity, any development programs designed by Indivior. However, Indivior has authority over all aspects of the development of such selected compounds.

Under terms of the agreement, the Group granted Indivior an exclusive license to use relevant patents and know-how in relation to the development and commercialization of product candidates selected by Indivior. Subject to agreed conditions, the Group and Indivior jointly own all intellectual property rights that are jointly developed and the Group or Indivior individually own all intellectual property rights that the Group or Indivior develop individually. The Group has retained the right to select compounds from the research program for further development in areas outside the interest of Indivior including Cough. Under certain conditions, but subject to certain consequences, Indivior may terminate the agreement.

In January 2018, the Group received, under the terms of the agreement, a non-refundable upfront fee of USD 5.0 million for the right to use the clinical candidate, ADX71441, including all materials and know-how related to this clinical candidate. In addition, the Group is eligible for payments on successful achievement of pre-specified clinical, regulatory and commercial milestones totaling USD 330 million and royalties on net sales of mid-single digits to low double-digits.

Addex Therapeutics │ Unaudited Interim Condensed Consolidated Financial Statements │Notes

On February 14, 2019, Indivior terminated the development of their selected compound, ADX71441. Separately, Indivior funds research at the Group, based on a research plan to be mutually agreed between the parties, to discover novel GABAB PAM compounds. These future novel GABAB PAM compounds, if selected by Indivior, become licensed compounds. The Group agreed with Indivior to an initial research term and duration of two years with a funding of USD 4 million over the period for the Group's R&D costs incurred, that can be extended by twelve-month increments. R&D costs are calculated based on the costs incurred in accordance with the contract. Following Indivior's selection of one newly identified compound, the Group has the right to also select one additional newly identified compound. The Group is responsible for the funding of all development and commercialization costs of its selected compounds and Indivior has no rights to the Group's selected compounds. The initial two-year research term was expected to run from May 2018 to April 2020. In 2019, Indivior agreed to an additional research funding of USD 1.6 million, for the research period. On October 30, 2020, the research term was extended until June 30, 2021 and Indivior agreed to additional research funding of USD 2.8 million. Effective May 1, 2021, the research term was extended until July 31, 2022 and Indivior agreed additional research funding of CHF 3.7 million, of which CHF 2.7 million was paid to the Group and CHF 1.0 million paid directly by Indivior to third party suppliers that are supporting the funded research program. In August 2022, the research agreement was extended until March 31, 2023 and Indivior agreed to additional research funding of CHF 0.85 million. The reserved indications, where Addex retains exclusive rights to develop its own independent GABAB PAM program, have also been expanded to include cough. Effective November 1, 2022, the research term was extended until June 30, 2023 and Indivior agreed to additional research funding of CHF 0.95 million. Effective July 1, 2023, the research agreement with Indivior has been extended until June 30, 2024 and Indivior committed additional research funding of CHF 2.7 million including CHF 1.1 million expected to be paid to the Group and CHF 1.6 million paid directly by Indivior to third party suppliers that are supporting the funded research program.

For the three-month period ended March 31, 2024, the Group recognized CHF 0.2 million as revenue in continuing operations (for the three-month period ended March 31, 2023: CHF 0.5 million) and recorded CHF 0.1 million in contract asset as of March 31, 2024 (December 31, 2023: CHF 0.1 million relating to contract assets and trade receivables).

Janssen Pharmaceuticals Inc. (formerly Ortho-McNeil-Janssen Pharmaceuticals Inc)

On December 31, 2004, the Group entered into a research collaboration and license agreement with Janssen Pharmaceuticals Inc. (JPI). In accordance with this agreement, JPI has acquired an exclusive worldwide license to develop mGlu2 PAM compounds for the treatment of human health. The Group is eligible to receive up to EUR 109 million in success-based development and regulatory milestone, and low double-digit royalties on net sales. The Group considers these various milestones to be variable considerations as they are contingent upon achieving uncertain, future development stages and net sales. For this reason, the Group considers the achievement of the various milestones as binary events that will be recognized as revenue upon occurrence.

No amounts have been recognized under this agreement for the three-month period ended March 31, 2024 and 2023.

16. Other income

Under grant agreements with Eurostars/Innosuisse the Group is required to complete specific research activities within a defined period of time. The Group's funding is fixed and received based on the satisfactory completion of the agreed research activities and incurring the related costs.

In July 2019, the Group was awarded a grant of CHF 0.5 million by Eurostars/Innosuisse to support the mGlu7 NAM program totally recognized as income as of December 31, 2021.

In September 2023, the Group was awarded a grant of CHF 0.5 million by Eurostars/Innosuisse to support the mGlu2 NAM program of which CHF 0.3 million were received in December 2023. As of April 2, 2024, following the Neurosterix Transaction, other income recognized through this grant in the first quarter of 2024 has been reclassed in the statements of comprehensive loss under "net loss from discontinued operations". The remaining funds and the associated deferred income amount of CHF 0.3 million as of March 31, 2024 has been recorded as assets and liabilities held for sale, respectively (see note 20).

The Group additionally recognized other income from IT consultancy agreements.
