Securities
Litigation
Financial
and Banking Regulatory Litigation
Securities litigation exposes issuers, officers and investors to significant reputational and financial risk through judicial and regulatory proceedings that often run in parallel. Disputes between market participants, liability claims and post-transaction litigation all demand a thorough understanding of market mechanisms and the applicable regulatory framework.
Our practice focuses primarily on proceedings before the Autorité des marchés financiers (AMF): market abuse investigations, regulatory inspections, analysis of notified charges, negotiation of settlements with the AMF’s enforcement division, representation before the Sanctions Committee and judicial appeals.
We handle cases involving misleading disclosures, insider dealing and market manipulation.
Where these matters trigger parallel criminal investigations, we also provide white-collar criminal defence. Listed issuers, corporate officers, financial intermediaries and institutional investors entrust us with their most sensitive proceedings.
our Interventions
We represent clients throughout AMF investigations and inspections, analyse the charges brought against them and build a comprehensive defence strategy. When sanctions are contemplated, we negotiate administrative settlement agreements (compositions administratives) or appear before the Sanctions Committee on their behalf. We also bring appeals against enforcement decisions, whether on behalf of issuers, market professionals or any individual or entity under scrutiny. Our in-depth knowledge of regulatory practice enables us to anticipate risks and manage both regulatory and media exposure.
When a criminal investigation is opened alongside administrative proceedings, we defend our clients at every stage of the judicial process: police custody, witness hearings, formal investigations and trial. Insider dealing, market manipulation and misleading disclosures frequently carry both administrative and criminal liability. We coordinate responses across authorities to ensure a consistent defence strategy and mitigate the risk of self-incrimination. This integrated approach allows us to anticipate the interplay between proceedings and protect our clients’ interests across the full spectrum of the dispute.

FAQ
AMF investigations into insider dealing, market manipulation or misleading disclosures expose issuers, officers and investors to financial penalties of up to EUR 100 million, or ten times the profit derived from the infringement, under Article L. 621-15 of the French Monetary and Financial Code. We assist clients from the investigation and inspection stage, analyse the charges notified and build a comprehensive defence strategy. Our in-depth knowledge of the AMF’s regulatory practices enables us to anticipate risks and manage both regulatory and media exposure simultaneously.
When sanctions are contemplated by the AMF, respondents have two main avenues: negotiating an administrative settlement (composition administrative) with the AMF’s enforcement division, or appearing before the Sanctions Committee. The administrative settlement mechanism, introduced by the Sapin II Act in 2016, allows cases to be resolved through a negotiated agreement subject to Committee validation. We handle the negotiation of such agreements, represent clients before the Sanctions Committee and bring appeals against enforcement decisions, whether on behalf of issuers, market professionals or any individual or entity under scrutiny.
Securities offences frequently carry both administrative liability before the AMF and criminal liability before the courts. Article L. 465-1 of the French Monetary and Financial Code punishes insider dealing with up to five years’ imprisonment and a fine of EUR 100 million, which may be increased to ten times the profit derived from the offence. We defend our clients throughout the criminal process: police custody, witness hearings, formal investigations and trial. We coordinate responses across administrative and criminal authorities to ensure a consistent defence strategy and mitigate incrimination risks.
Listed issuers, corporate officers, financial intermediaries and institutional investors entrust us with their most sensitive proceedings.
