May 1 (Reuters) - London Stock Exchange Group ( LDNXF )

said on Wednesday it has agreed to purchase shares worth 500

million pounds ($624 million) from a consortium of investors

that sold data and analytics firm Refinitiv to the bourse

operator.

The purchase is in line with LSEG's plans to buy back shares

as it completes the integration of Refinitiv, which it bought in

2021 from investors including Blackstone, Thomson Reuters ( TRI )

, Canada's CPPIB and Singapore's GIC.

LSEG said on Wednesday it bought the shares off the market

for about 87.7 pounds per share, and that the deal completes

buybacks worth 1 billion pounds it had indicated it would

execute during the year.

LSEG shares closed the day at 88.4 pounds per share.

The company last month said that 500 million pounds in a

directed buyback was completed in its first quarter, and

shareholders had approved a further buyback of up to a billion

pounds in total in 2024.

Thomson Reuters ( TRI ), owner of Reuters News, holds a minority

stake in LSEG, which pays Reuters for news.
