Prologis piles pressure on SEGRO as takeover deadline looms Proactive uses images sourced from ShutterstockPrologis has intensified its pursuit of SEGRO PLC (LSE:SGRO), publicly attacking the warehouse landlord's defence a day before a deadline that forces the US giant to bid or walk away. The FTSE 100 property group rejected a third approach from Prologis on Monday, worth 993p a share, or about £13.5 billion. Under Takeover Panel rules, Prologis must announce a firm intention to bid or step away by 5 pm on Tuesday, the so-called put up or shut up deadline. The US firm also invoked history, noting the SEGRO board rejected an earlier approach in March 2024 within 72 hours. The proposal comprises 0.089 new Prologis shares for each SEGRO share, with a partial cash alternative of up to £2.7 billion, equal to a fifth of the total.
