Financial Summary:

Income is primarily driven by amounts received under our funded research collaboration with Indivior. During the first half of 2021, income increased by CHF 0.1 million to CHF 2 million compared to the first half of 2020. During the second quarter of 2021, income increased by CHF 0.1 million compared to CHF 1.1 million in the second quarter of 2020.

R&D expenses increased by CHF 0.6 million to CHF 6.5 million in the first half of 2021 compared to CHF 5.9 million in the first half of 2020, primarily due to the net effect of reduced costs associated with our dipraglurant phase 2b/3 PD-LID clinical study and increased costs related to our dipraglurant blepharospasm program, GABA_B PAM program and other discovery programs. During the second quarter of 2021, these expenses increased by CHF 1.4 million compared to the second quarter of 2020 primarily due to increased costs for dipraglurant PD-LID and dipraglurant blepharospasm programs. Research and development expenses consist primarily of costs associated with research, preclinical and clinical testing, and related staff costs. They also include depreciation of laboratory equipment, costs of materials used in research, costs associated with renting and operating facilities and equipment, as well as fees paid to consultants, patent costs and other outside service fees and overhead costs. These expenses include costs for proprietary and third-party R&D.

G&A expenses slightly decreased by CHF 0.1 million to CHF 3.2 million in the first half of 2021 compared to CHF 3.3 million in the first half of 2020, primarily due to reduced share-based compensation costs. During the second quarter of 2021, these expenses increased by CHF 0.3 million compared to the second quarter of 2020 mainly due to higher professional fees relating to setting-up our US shelf registration and "at-the-market" (ATM) ADS equity sale program with Cantor Fitzgerald.

The net loss is primarily driven by the evolution of the research and development costs. During the first half of 2021, the net loss slightly decreased by CHF 0.1 million to CHF 7.3 million compared to the first half of 2020. During the second quarter of 2021, the net loss increased by CHF 1.6 million to CHF 4.7 million compared to the second quarter of 2020.

Basic and diluted loss per share decreased to CHF 0.22 for the first half of 2021, compared to CHF 0.28 for the first half of 2020. For the second quarter of 2021, the basic and diluted loss per share increased to CHF 0.14 compared to CHF 0.12 for the second quarter of 2020.

Cash and cash equivalents amounted to CHF 18.1 million as of June 30, 2021 compared to CHF 20.7 million as of June 30, 2020. The decrease was primarily due to cash used in operating activities partially offset by the proceeds from the capital increase executed on January 8, 2021 and research funding from Indivior relating to our research collaboration.

About Addex Therapeutics:
Addex Therapeutics is a clinical-stage pharmaceutical company focused on the development and commercialization of an emerging class of novel orally available small molecule drugs known as allosteric modulators for neurological disorders. Allosteric modulators offer several potential advantages over conventional non-allosteric molecules and may offer an improved therapeutic approach to conventional "orthosteric" small molecule or biological drugs. Addex's allosteric modulator drug discovery platform targets receptors and other proteins that are recognized as essential for therapeutic intervention. Addex's lead drug candidate, dipraglurant (mGlu5 negative allosteric modulator or NAM), is in a pivotal registration clinical trial for Parkinson's disease levodopa induced dyskinesia (PD-LID). Addex is also investigating dipraglurant's therapeutic use in blepharospasm (a type of dystonia), for which a clinical trial is expected to be initiated in Q3 2021. Addex's third clinical program, ADX71149 (mGlu2 positive allosteric modulator or PAM), developed in collaboration with Janssen Pharmaceuticals, Inc., is in a Phase 2a proof of concept clinical trial for the treatment of epilepsy. Indivior PLC has licensed Addex's GABA_B PAM program for the development of drug candidates with a focus in addiction. Preclinical programs ongoing with Addex include GABA_B PAM for CMT1A, mGlu7 NAM for PTSD, mGlu2 NAM for mild neurocognitive disorders, mGlu4 PAM for Parkinson's disease and mGlu3 PAM for neurodegenerative disorders. Addex shares are listed on the SIX Swiss Exchange and American Depositary Shares representing its shares are listed on the NASDAQ Capital Market, and trade under the ticker symbol "ADXN" on each exchange.
