Finally, we are now evaluating the future development of ADX71149, our mGlu2 PAM after regaining full control of this asset.”

Operating Highlights:

• Launched Neurosterix with Perceptive Advisors, raising USD 65 million in Series A to accelerate the development of a preclinical portfolio including M4 PAM for schizophrenia;
• Received CHF 5.0 million and 20% of equity interest in Neurosterix;
• Successfully completed funded research phase of the Indivior collaboration with both Indivior and Addex each selecting GABAB PAM drug candidate for further development in SUD and chronic cough, respectively;
• Repositioned our phase 2 mGlu5 NAM asset, dipraglurant in brain injury recovery
• Regained rights to our phase 2 mGlu2 PAM asset, ADX71149
  
  

Key 2024 Financial Data

* The comparative information has been re-presented due to discontinued operations that have been reclassed to the financial line called “Net profit or loss from discontinued operations” following Neurosterix transaction.

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 the Group and discontinued operations, including the net gain from the sale of a part of our business and discontinued operating activities related to income and expenses of divested activities by the Group during 2024 and 2023 periods, respectively. The net gain from the sale of a part of our business, the income and expenses from discontinued operating activities have been reclassed to the financial line called “Net profit or loss from discontinued operations.”

During the 2024 period, net profit from discontinued operations amounted to CHF 12.0 million, and was primarily related to the net gain of CHF 13.9 million from the sale of part of our business, partially offset by the net loss of CHF 1.9 million from discontinued operating activities. During the 2023 period, the Group incurred a net loss from discontinued operations of CHF 8.1 million.

During the 2024 period, net profit amounted to CHF 7.1 million, primarily related to the net profit from discontinued operations of CHF 12.0 million partially offset by the net loss from continuing operations of                 CHF 4.9 million. During the 2023 period, the Group incurred a net loss of CHF 10.6 million of which CHF 8.1 million was related to operating discontinued activities.

Diluted net gain per share amounted to CHF 0.04 for 2024, compared to a diluted net loss per share of CHF 0.14 for 2023.

Cash and cash equivalents decreased to CHF 3.3 million at December 31, 2024, compared to CHF 3.9 million at December 31, 2023. The decrease of CHF 0.6 million between December 31, 2024 and December 31, 2023 is primarily due to the cash used in operating activities, partially offset by gross proceeds of CHF 5.0 million from the Neurosterix Transaction received in April 2024.

All financial variances described below relate to continuing operations:

Income is primarily driven by amounts received under our funded research collaboration with Indivior, recognized as related costs are incurred. In 2024, income decreased by CHF 1.2 million to CHF 0.4 million in 2024 compared to CHF 1.6 million in 2023, primarily due to the completion of the research agreement on June 30, 2024. On August 27, 2024, Indivior selected a compound for future development in substance use disorder and undertakes all future development of its selected compound.

R&D expenses primarily relate to our GABAB PAM program and decreased by CHF 0.3 million to CHF 0.8 million in 2024 compared to CHF 1.2 million in 2023, primarily due to the completion of the research agreement with Indivior on June 30, 2024.

G&A expenses decreased by CHF 0.4 million to CHF 2.3 million in 2024 compared to CHF 2.7 million in 2023, primarily due to reduced D&O insurance costs.

The net loss from continuing operations increased by CHF 2.4 million to CHF 4.9 million in 2024 compared to CHF 2.5 million in 2023, primarily due to reduced revenue and increased costs related to the share of the net loss of the Neurosterix Group.
