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, 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 the six-month and three-month periods ended June 30, 2024 and 2023, 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.” The net profit from discontinued operations amounted to CHF 11.98 million for the six-month period ended June 30, 2024, and primarily related to the net gain from the sale of a part of our business of CHF 13.96 million, partially offset by the net loss from operating discontinued activities of CHF 1.98 million. During the same period ended June 30, 2023, the Group incurred a net loss from discontinued operations of CHF 4.19 million. The net profit amounted to CHF 9.79 million for the six-month period ended June 30, 2024 and primarily related to the net profit from discontinued operations of CHF 11.98 million partially offset by the net loss from continuing operations of CHF 2.19 million. During the same period ended June 30, 2023, the Group incurred a net loss of CHF 5.08 million of which CHF 4.19 million was related to operating discontinued activities. Diluted net profit per share amounted to CHF 0.06 for the six-month period ended June 30, 2024, compared to a diluted net loss per share of CHF 0.08 for the same period ended June 30, 2023. Cash and cash equivalents decreased to CHF 3.8 million at June 30, 2024, compared to CHF 7.2 million at June 30, 2023. The decrease of CHF 3.4 million between June 30, 2024 and June 30, 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. During the first half of 2024, income decreased by CHF 0.8 million to CHF 0.3 million compared to CHF 1.1 million in the first half of 2023. During the second quarter of 2024, income decreased by CHF 0.5 million to CHF 0.1 million compared to CHF 0.6 million in the first quarter of 2023. R&D expenses primarily relate to our GABAB PAM program and remain stable at around CHF 0.5 million for both first half of 2024 and 2023 and at CHF 0.3 million for both second quarter of 2024 and 2023. G&A expenses increased by CHF 0.1 million to CHF 1.5 million in the first half of 2024 compared to CHF 1.4 million in the first half 2023, primarily due to increased legal fees. G&A expenses remain stable at around CHF 0.7 million for both second quarter 2024 and 2023. The net loss from continuing operations increased by CHF 1.3 million to CHF 2.2 million in the first half 2024 compared to CHF 0.9 million in the first half 2023, and by CHF 0.9 million to CHF 1.4 million in the second quarter of 2024 compared to CHF 0.5 million in the second quarter of 2023 primarily due to reduced income and the share of net loss incurred by Neurosterix from April 2, 2024 to June 30, 2024 in accordance with IFRS.
