In response to media inquiries, Halliburton Company issued the following statement to certain media outlets:

Response to European Commission Phase II Review Extension

Halliburton and the European Commission have reached an agreement under which the Commission will extend its Phase II review of Halliburton’s pending acquisition of Baker Hughes by 20 working days. Halliburton believes the extension will facilitate the Commission’s review of a remedies package, which will be formally offered by the company in the near future in order to address the Commission’s concerns. Halliburton continues to work cooperatively with the Commission, as well as all other competition enforcement authorities that have expressed an interest in the proposed transaction. Halliburton remains focused on closing the transaction as early as possible in 2016.
