Halliburton Company distributed the following communication to its customers on or after April 7, 2015.

Dear valued customer,

I’m pleased to bring you news of important steps on our journey to close the pending acquisition of Baker Hughes. At the end of March, Halliburton’s stockholders voted overwhelmingly to approve the Company’s proposal to issue shares of Halliburton common stock as necessary for the proposed transaction. In addition, Baker Hughes’s stockholders also voted overwhelmingly to adopt the merger agreement and thereby approved the proposed acquisition. The stockholder votes were significant and we are excited to have these milestones behind us.

Today, we announced Halliburton made the decision to separately market for sale its Fixed Cutter and Roller Cone Drill Bits, its Directional Drilling and its Logging-While-Drilling (LWD)/Measurement-While-Drilling (MWD) businesses as part of the competition authorities’ review of the pending transaction. Although we prefer to retain these assets, we will be required to divest some of our overlapping businesses to obtain competition authorities’ approval as anticipated when we announced the Halliburton-Baker Hughes transaction. Competition authorities will want to ensure there will be other sustainable competitors in the market, and we know that because of their strong brands, great products and dedicated employees, these businesses can satisfy that objective.

The final sale of these businesses will be subject to our ability to negotiate acceptable terms and conditions, the approval of Halliburton’s Board of Directors and final approval of the Baker Hughes acquisition by competition authorities. We anticipate that we will complete the sale of these businesses in the same timeframe as the expected closing of the pending Baker Hughes acquisition late in the second half of 2015.

Continued focus

As we progress with our work to close the pending transaction and the sale of these businesses, Halliburton remains focused on providing you the same safe, reliable, cost-effective service you expect from us. Our commitment to superior service quality and safe, environmentally responsible operations is unwavering, and our employees remain dedicated to consistently and efficiently meeting your needs. It’s important to note, we will continue to operate as one Company until we complete the sale of these businesses and we pledge our commitment to you to adhere to the following guiding principles:

 

    We intend to sell these businesses to reputable companies that will manage them for continued success and maintain existing contractual obligations.

 

    After the acquisition of Baker Hughes is completed, we will continue to provide drilling, LWD/MWD and roller cone/fixed cutter capabilities with the addition of Baker Hughes product lines to replace the businesses we are selling.


    We will maintain the Halliburton way of doing business. You will see continuity in the way we work with you, and we will remain focused on service quality and safety throughout the divestiture and subsequent integration processes.

 

    We are keeping our eyes on the ball. We will do our utmost to maximize our focus on you and minimize any distractions as we work to complete the acquisition.

Building a strong future

We are more confident now than ever that the combination of Halliburton and Baker Hughes will result in a broader, more cost-effective service offering, and provide compelling value for our customers. Further, we believe this acquisition will accelerate the execution of our key strategies in unconventionals, deep water and mature fields, and create a bellwether global oilfield service company that will allow us to bring you improved solutions, lower cost and enhance service quality.

We will continue to update you on our progress to close the pending acquisition, as appropriate. If you have any questions, please let me know.

Sincerely,
