Key 2023 Financial Data

Financial Summary:
Income primarily relates to amounts received under our funded research collaboration with Indivior and is recognized as related costs are incurred. In 2023, income increased by CHF 0.2 million to CHF 1.6 million compared to CHF 1.4 million in 2022. R&D expenses decreased by CHF 7.7 million to CHF 7.0 million in 2023 compared to CHF 14.7 million in 2022, primarily due to decreased dipraglurant related external research and development activities. G&A expenses decreased by CHF 2.3 million to CHF 5.0 million in 2023 compared to CHF 7.3 million in 2022, primarily due to decreased share-based service costs and D&O insurance costs. Our net loss decreased by CHF 10.2 million to CHF 10.6 million in 2023 compared to CHF 20.8 million in 2022, primarily due to reduced R&D expenses. Basic and diluted loss per share decreased to CHF 0.14 in 2023 compared to CHF 0.46 in 2022. Cash and cash equivalents decreased to CHF 3.9 million in 2023, compared to CHF 7.0 million in 2022. The decrease of CHF 3.1 million is primarily due to the cash used in our operating activities, partially offset by the proceeds from financing activities mainly related to the USD 5 million equity offering executed on April 3, 2023 and to a lesser extent research funding from Indivior.
