The AMF Enforcement Committee fines three individuals and one legal entity a total of €700,000 for insider dealing breaches
In its decision of 5 May 2025, the Enforcement Committee imposed fines of €150,000, €400,000, €50,000 and €100,000 respectively on Karen Pignet-Aiach, Gad Aiach, Michaël Chetrit and Mikostart for having disclosed or used inside information, or having recommended an investment on the basis of this inside information.
Ms Pignet-Aiach was accused of having transmitted information about Lysogene having obtained approval from the Food and Drug Administration (FDA), the US agency responsible for monitoring foodstuffs and drug products, to begin clinical trials for one of its drug candidates to her ex-husband, Mr Aiach. Mr Aiach was accused of having used this information to acquire Lysogene shares, and of having transmitted this information to two of his friends, one of whom was Mr Chetrit, and of having recommended an investment to his partner on the basis of this information. Mr Chetrit and Mikostart were also accused of having used this information to acquire Lysogene shares.
The Enforcement Committee first held that the information in question constituted inside information on 10 February 2021 at around 7pm, at the latest. It found that Ms Pignet-Aiach, the CEO of Lysogene, was in possession of this inside information on 10 February 2021 at 7.29pm, at the latest.
For each of the respondents, the Committee then examined all the indicators relating to the existence of plausible channels for transmitting the inside information, the atypical nature of the disputed operations, their timing and the eagerness to execute them, as well as the explanations adduced by the respondents to justify their transactions.
On the basis of this analysis, the Enforcement Committee held that Ms Pignet-Aiach had transmitted this inside information to Mr Aiach, and that the latter had used it to acquire Lysogene shares and had transmitted it to Mr Chetrit, who in turn had used it on behalf of Mikostart. It also found that Mr Aiach had recommended an investment to his partner on the basis of this inside information. However, the Committee held that the breach of having transmitted this inside information to a second friend, of which Mr Aiach was also accused, was not proven.
An appeal may be lodged against this decision.
