Key 2013 Financial Data

2013 Financial Summary

Income was CHF0.1 million in 2013 compared to CHF0.1 million in 2012, and corresponds to the first installment recognized under a grant received from The Michael J. Fox Foundation for Parkinson's Research to support characterization of dipraglurant for Parkinson's disease levodopa-induced dyskinesia.

Research & Development expenses decreased by 47% to CHF10.9 million in 2013 compared to CHF20.6 million in 2012, primarily due to our significant reduction in headcount and pipeline prioritization.

General & Administration expenses decreased by 11% to CHF5.8 million in 2013 compared to CHF6.5 million in 2012 mainly due to our reduced headcount off-set by the costs of restructuring.

Net Loss decreased by 46% to CHF14.5 million for 2013 compared to CHF27.0 million for 2012, mainly due to the decrease in our operating expenses.

Cash and Cash Equivalents amounted to CHF2.9 million at 31 December 2013, compared to CHF15.3 million at the end of 2012. 2013 cash burn of CHF12.3 million is mainly due to the cash used in operations of CHF16.0 million, off-set by the proceeds from the capital increase, net of costs, of CHF3.1 million and proceeds from the sale of property plant and equipment of CHF0.5 million.

Outlook: Based on current expectations, full year 2014 cash utilization guidance is CHF2.5 million.

Organization and Strategy

The Company has completed its reorganization and reduced its headcount to 5 full time equivalents and significantly reduced its facilities accordingly. The Company is focused on preserving the value of its assets, including the intellectual property surrounding its portfolio of allosteric modulator drug candidates and its proprietary allosteric modulator technology platform, while pursuing a strategy to secure the resources necessary to advance the pipeline and maximize value for shareholders. In parallel the Company continues to enter collaborations with academic institutions, government organizations and patient groups to advance its portfolio of drug candidates for the benefit of patients.

2013 Annual Report

The 2013 Annual report will be available at latest by 31 May 2014. The Company has been granted an extension, by the SIX Exchange Regulation, of the deadline to publish its 2013 annual report of 30 April 2014 until 31 May 2014 due to resource prioritization following its restructuring.

About Addex Therapeutics

Addex Therapeutics (www.addextherapeutics.com) is a discovery and development stage company focused on advancing innovative oral small molecules utilizing its pioneering allosteric modulation-based drug discovery platform. The Company's two lead products are being investigated in Phase 2 clinical testing: dipraglurant (an mGlu5 negative allosteric modulator or NAM) is being developed by Addex to treat Parkinson's disease levodopa-induced dyskinesia (PD-LID) and rare forms of dystonia; and ADX71149 (mGlu2 positive allosteric modulator or PAM) is being developed in collaboration with Janssen Pharmaceuticals, Inc. Addex also has several preclinical programs including: GABAB receptor positive allosteric modulator (PAM) for addiction, Charcot-Marie-Tooth (type 1a) disease, spasticity in patients with multiple sclerosis (MS), pain, overactive bladder, autism and other disorders; mGlu4 PAM for MS, Parkinson's disease, anxiety and other diseases; mGlu2 NAM for treatment resistant depression and cognitive deficits; and mGlu7 NAM for psychosomatic disorders. Allosteric modulators are an emerging class of small molecule drugs which have the potential to be more specific and confer significant therapeutic advantages over conventional "orthosteric" small molecule or biological drugs. The Company uses its proprietary discovery platform to target receptors and other proteins that are recognized as essential for the therapeutic modulation of important diseases with unmet medical needs.
