Investors in Banca Monte dei Paschi di Siena SpA rejected a €25 billion (approximately $27.9 billion) plan to acquire Banco BPM SpA. This move represents a significant setback for Monte Paschi CEO Luigi Lovaglio's efforts to fend off a takeover bid from Intesa Sanpaolo SpA. The proposed acquisition of Banco BPM failed to secure the required two-thirds majority support at Thursday's meeting.
