Prologis Inc. submitted a final £14.0 billion ($18.72 billion) proposal to acquire UK-based SEGRO plc.

The revised offer provides 0.0920 new Prologis shares for every SEGRO share. It includes an increased partial cash alternative totaling up to £3.5 billion. The bid values each SEGRO share at 1,031.7 pence.

Prologis confirmed it will not increase this final offer. The company urged SEGRO’s board to request a deadline extension beyond July 22 from UK regulators. SEGRO shares rose more than 4% in London following the announcement. The acquisition aims to significantly expand Prologis’s logistics footprint across Europe.
