This follows a sale in May of about $3.4 billion shares in the bourse operator as the investor group seeks to offload its stake in LSEG. The consortium, which includes Canada's CPPIB and Singapore's GIC, aims to sell a total of about 43.1 million shares over time in LSEG through the offering, a directed buyback and a sale of call options, bookrunners said. LSEG separately said it plans to buy back about 750 million pounds worth of limited-voting ordinary shares through an off-the-market purchase.
