Financial Summary:

Under IFRS, the sale of our allosteric modulator drug discovery platform and unpartnered preclinical portfolio to Neurosterix on April 2, 2024, required the identification of continuing operations related to retained programs by Addex and discontinued operations for the three-month period ended March 31, 2024 and 2023. The income and expenses from discontinued operations have been reclassed to the financial line called "Net loss from discontinued operations". All financial variance described below relate to continuing operations.

Income decreased by CHF 0.3 million to CHF 0.2 million in the first quarter 2024 compared to CHF 0.5 million in the first quarter 2023, primarily driven by amounts received under our funded research collaboration with Indivior, recognized as related costs are incurred.

R&D expenses primarily relate to our GABAB PAM program and remain stable at CHF 0.3 million for both first quarters of 2024 and 2023.

G&A expenses increased by CHF 0.2 million to CHF 0.8 million in the first quarter 2024 compared to CHF 0.6 million in the first quarter 2023, primarily due to legal fees.

The net loss from continuing operations increased by CHF 0.4 million primarily due to reduced income and increased G&A.

Basic and diluted loss per share from continuing operations remain stable at CHF 0.01 for the first quarter 2024 compared to the first quarter 2023.

Cash and cash equivalents decreased to CHF 1.6 million at March 31, 2024, compared to CHF 5.6 million at March 31, 2023. The decrease of CHF 5.4 million between March 31, 2024 and March 31, 2023 is primarily due to the cash used in operating activities, partially offset by funds raised from one single institutional investor in April 2023. Gross proceeds of CHF 5.0 million from Neurosterix's transaction was received in April 2024.
