The AMF Enforcement Committee fines Visiomed and its former directors, Éric Sebban and Olivier Hua, for market manipulation. It also fines Negma Group Ltd for breach of its reporting obligations
Executive Summary
The AMF Enforcement Committee imposed fines on Visiomed and its former directors Éric Sebban and Olivier Hua for market manipulation, and on Negma Group Ltd for failing to meet reporting obligations. This enforcement action underscores the AMF's rigorous enforcement of market abuse rules under EU Regulation 596/2014 (MAR), serving as a critical reminder for listed companies, directors, and major shareholders to prioritize compliance with manipulation prohibitions and threshold crossing disclosures. It matters because it demonstrates personal liability for executives and ongoing scrutiny of disclosure failures, potentially influencing enforcement trends in 2026 amid strengthened AMF powers. #
What Changed
This is an enforcement decision rather than new regulatory changes, reinforcing existing requirements under MAR (Regulation (EU) No 596/2014), transposed into AMF's General Regulation (Book VI on market abuse). It highlights prohibitions on market manipulation (e.g., disseminating false or misleading information or engaging in fictitious transactions to influence prices) and mandatory reporting of shareholdings crossing 5% thresholds or changes therein for listed issuers. No novel rules are introduced, but it aligns with AMF's 2026 priorities on market integrity and recent legislative pushes to expand enforcement tools like web scraping and penalty payments.
Suggested Considerations
- Conduct internal audits: Review past and current communications, trading patterns, and disclosures for manipulation risks or unreported positions.
- Enhance monitoring systems: Implement surveillance for market abuse, including automated tools for detecting unusual trading or information dissemination.
- Train personnel: Educate directors, compliance teams, and traders on MAR prohibitions and reporting thresholds; report suspicions via AMF forms.
- Update policies: Ensure prompt filing of threshold declarations (e.g., within 4 trading days for >5% holdings) and consistency with prospectus rules.
- Cooperate with regulators: Prepare for AMF investigations, leveraging potential penalty reductions for early cooperation as per emerging powers.
