Thomson Reuters and Blackstone in Discussions

with London Stock Exchange Group Regarding the Refinitiv Business

TORONTO, July 26, 2019 – Thomson Reuters (TSX/NYSE: TRI) confirms that it and private equity funds affiliated with Blackstone are in discussions related to a possible acquisition of Refinitiv by the London Stock Exchange Group plc (LSEG) for a total enterprise value of approximately US$27 billion. New LSEG shares are contemplated to be issued as consideration in full for Refinitiv’s equity value, after adjusting for Refinitiv’s net debt and other adjustments.

The parties anticipate that the transaction would result in Thomson Reuters holding an approximate 15% stake in LSEG if completed.

The Refinitiv business is currently 55% owned by private equity funds managed by Blackstone and 45% by Thomson Reuters. Reuters News 30-year agreement signed last year with Refinitiv will continue if ownership of Refinitiv changes.

There can be no certainty that these discussions will progress or that a transaction will be forthcoming.

Any further announcements will be made as appropriate.
