Monte Paschi Board Member Resigns Amid Insider Trading Probe (MPS: MPS)

A Monte Paschi di Siena (MPS) board member, Stefano Di Stefano, resigned effective immediately, citing personal reasons and in connection with ongoing investigations into suspected insider trading. Di Stefano, also director in the Ministry of Economy’s Directorate for Corporate Shareholdings and Protection of Strategic Assets, is alleged to have bought about €100,000 in shares based on confidential MPS information. The probe follows a probe of potential coordination between MPS CEO Luigi Lovaglio and top MPS investors in the Mediobanca acquisition approved in September 2025. Di Stefano, who has served on MPS’s board since April 2022 and chaired its Risk and Sustainability Committee, chairs a department with access to sensitive corporate information and is under scrutiny regarding transactions and the application of Italy’s “golden power” veto in share sales and other operations. Parliament is questioning the government on Di Stefano’s role in the Mediobanca deal and in the UniCredit–Banco BPM infringement proceeding, with the Ministry of Economy issuing no public comment.
