Clarification regarding the article published yesterday in the newspaper Les Echos related to the investigation by the French market authorities

AB Science SA (Euronext - FR0010557264 - AB) has taken note of the article published yesterday in the newspaper Les Echos regarding an investigation led by the Financial Markets Authority (Autorité des Marchés Financiers or AMF) related to AB Science financial information and market trading.

AB Science reminds that this investigation which started in 2017 was disclosed when the Company released its annual financial report for the fiscal year ended December 31, 2018.

AB Science is puzzled to read in the press an inaccurate and unfounded statement of the AMF investigators, in violation of the rights of the Company and its management, despite the fact that the investigation is still ongoing and that no formal grievances have been notified.

AB Science, which does not intend to comment on an ongoing investigation, reminds that the facts outlined in this article are formally contested and that the management of the Company is totally confident about the outcome of this investigation.
