## Exhibit 99.1

**EXHIBIT 99.1**

**Addex Regains Nasdaq Listing Compliance**

**Ad Hoc Announcement Pursuant to Art. 53 LR**

**Geneva, Switzerland, February 9, 2023 -** Addex Therapeutics (SIX and Nasdaq: ADXN), a clinical-stage pharmaceutical company pioneering allosteric modulation-based drug discovery and development, today announced notification from The Nasdaq Stock Market LLC (Nasdaq) that it has regained compliance with the minimum bid price requirement of $1.00 per ADS share under Nasdaq Listing Rule 5550(a)(2) and currently meets all other applicable criteria for continued listing.

Addex announced on November 3, 2022 that it had been notified by Nasdaq that its ADSs were not in compliance with the minimum bid price rule. To regain compliance, Addex was required to maintain a minimum closing bid price of $1.00 for at least 10 consecutive business days. This requirement was met on February 7, 2023.

**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, 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. Addex's second clinical program, dipraglurant (mGlu5 negative allosteric modulator or NAM), is under evaluation for future development in a range of indications. Indivior PLC has licensed Addex's GABAB PAM program for the development of drug candidates, with a focus on substance use disorder. Addex is also advancing a broad preclinical pipeline, which includes development of a range of GABAB PAMs for CMT1A, chronic cough and several types of pain, mGlu7 NAM for stress related disorders, mGlu2 NAM for mild neurocognitive disorders and depression, M4 PAM for schizophrenia and other forms of psychosis, as well as mGlu4 PAM and mGlu3 PAM. 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.
