The AMF has required the suspension of MEXEDIA shares and calls on investors to be vigilant
Executive Summary
The AMF enforced a trading suspension on MEXEDIA S.p.A. shares on Euronext from 11 September 2025 to 30 September 2025 due to indicators of **pump and dump** market abuse, urging investors to exercise extreme caution against unauthorized high-upside recommendations. This enforcement action underscores the AMF's proactive market surveillance and highlights ongoing risks of manipulative practices in listed equities, serving as a reminder for firms to bolster internal controls against such schemes. Compliance teams should note this as a signal of heightened regulatory scrutiny on price manipulation, potentially informing future enforcement trends. #
What Changed
This is an enforcement action rather than new regulatory changes; no legislative or rule amendments are introduced. Key elements include: - AMF's invocation of financial markets and market abuse regulations to mandate trading suspension via Euronext. - Explicit warning on pump and dump tactics, defined as unauthorized promotions inflating share prices for insider sales, leading to investor losses. - Follow-up resumption of trading on 1 October 2025 after suspension ended, with continued vigilance calls. #

Key Dates
Compliance Impact
Urgency: Medium - This is a resolved, case-specific enforcement (suspension lifted 1 October 2025), not imposing new firm-wide rules, reducing immediate action needs as of January 2026. It matters for market abuse surveillance programs, signaling AMF's focus on pump-and-dump in equities, which could elevate fines or scrutiny in audits; firms should review systems for similar indicators to mitigate
