   Financial Summary: 
 
   Income increased by CHF 1.0 million to CHF 3.9 million in 2020 compared 
to CHF 2.8 million in 2019, primarily due to amounts received under the 
licensing and research agreement with Indivior, recognized as related 
costs are incurred. 
 
   R&D expenses decreased by CHF 2.1 million to CHF 10.4 million in 2020 
compared to CHF 12.4 million in 2019, primarily due to delays in 
starting certain clinical development activities due to the global 
coronavirus pandemic. R&D 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 increased by CHF 0.7 million to CHF 5.7 million in 2020 
compared to CHF 5.0 million in 2019 mainly due to the increase of CHF 
1.3 million relating to increased directors and officer's liability 
insurance premiums partially offset by a decrease of CHF 0.5 million in 
audit and legal fees. 
 
   The net loss for 2020 was CHF 12.9 million compared to CHF 14.8 million 
for 2019 primarily due to the decrease in R&D costs. Basic and diluted 
loss per share decreased to CHF 0.48 for 2020, compared to CHF 0.56 for 
2019. 
 
   Cash and cash equivalents amounted to CHF 18.7 million at December 31, 
2020 compared to CHF 31.5 million at December 31, 2019. This decrease of 
CHF 12.8 million is mainly due to the net loss.

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 
poised to start a pivotal registration clinical trial for Parkinson's 
disease levodopa induced dyskinesia (PD-LID) in H1 2021. 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 H1 
2021. Addex's third clinical program, ADX71149 (mGlu2 positive 
allosteric modulator or PAM), developed in collaboration with Janssen 
Pharmaceuticals, Inc, is scheduled to enter a phase 2a proof of concept 
clinical study for the treatment of epilepsy in Q2 2021. Addex's GABAB 
PAM program has been licensed to Indivior PLC who are focused on 
development for the treatment of addiction. Preclinical programs include 
GABAB 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 is listed on the SIX Swiss 
Exchange and the NASDAQ Capital Market and trades under the ticker 
symbol "ADXN".
