LONDON (AFP) - The London Stock Exchange on Sunday (Feb 26) said it is "highly unlikely" it will be able to meet antitrust conditions set by Brussels for its tie-up with Deutsche Boerse, throwing the merger into doubt.
The announcement by LSE, which also operates the Milan stock exchange, is the latest twist in its longstanding attempt to merge with the German stock exchange operator.
The LSE said it had examined the European Commission's request to divest its majority stake in Italian trading unit MTS, concluding it could not commit to such a request.
"The LSEG Board believes that it is highly unlikely that a sale of MTS could be satisfactorily achieved, even if LSEG were to give the commitment," LSE said in a statement.
The announcement comes after the Commission raised new concerns on Feb 16 about the merger, giving the company a deadline of midday on Feb 27 to outline a proposal for divesting in MTS.
"Based on the Commission's current position, LSEG believes that the Commission is unlikely to provide clearance for the merger," it added.
The London Stock Exchange did not put an end to the possibility of a tie-up, however, saying it would continue to seek to implement the deal.
Deutsche Boerse, which also operates the Luxembourg-based clearing house Clearstream and the derivatives platform Eurex, confirmed the decision on MTS and said a final decision from Brussels was expected within weeks.
"The parties will await the further assessment by the European Commission and currently expect a decision by the European Commission on the merger of DBAG and LSEG by the end of March 2017," Deutsche Boerse said in a statement.
The planned merger has drawn criticism from France, Belgium, Portugal and the Netherlands, fearful for their own stock exchanges, owned by Euronext.
Last month LSE agreed to offload the French arm of clearing house LCH to European rival Euronext, as part of efforts to address EU competition concerns.
LSE said on Sunday it viewed the LCH sale an "effective and capable" remedy to competition concerns, deeming the MTS demand "disproportionate".
An LSE-Deutsche Boerse merger would create a financial markets behemoth competing with the likes of the Chicago Mercantile Exchange and ICE in the United States, as well as the Hong Kong stock exchange in Asia.
Fears over such a deal have already scuppered two attempts at a merger in 2000 and 2005.
Beyond competition concerns, the proposed merger has also been shaken by Britain's decision last year to leave the EU which has created uncertainty around London's status as a European financial capital.
