The London Stock Exchange Group plc (LSE) and Deutsche Boerse AG issued a joint statement on Friday indicating that their planned merger is not contingent on the outcome of the UK’s vote to pull out of Europe.

The LSE and Deutsche Boerse boards “remain fully committed to the agreed and binding merger terms, and continue the process of obtaining the necessary approvals,” the two stock exchange operators say in the joint statement.

LSE shareholders will be asked to approve the deal at its general meeting on July 4, and Deutsche Boerse shareholders can tender their shares until the end of the exchange offer period on July 12.

“The boards believe that the outcome of the referendum does not impact the compelling strategic rationale of the merger,” the exchange operators add, and they remain in talks with their respective governments and regulators to seek approval of the deal.

“The decision of the U.K. to leave the EU makes it ever more important to maintain and foster ties between the U.K. and Europe. We are convinced that the importance of the proposed combination of Deutsche Boerse and LSEG has increased even further for our customers and will provide benefits for them as well as our shareholders and other stakeholders,” says Joachim Faber, chairman of the supervisory board of Deutsche Boerse.
