Manager Talking Points

Use these talking points to guide your conversations with employees about Baker Hughes’ merger with Halliburton.

Today’s News

Today our company announced an agreement that will create a company with a truly comprehensive portfolio of solutions.

By combining with Halliburton, we will combine two highly complementary portfolios to deliver an unsurpassed depth and breadth of solutions to our customers.

As Martin Craighead told his leadership team today, he envisions a new company with a greater ability to grow, and a greater capacity to have a positive impact on the world.

Why Are We Doing This?

Baker Hughes was approached by Halliburton with a proposal to combine our companies.

Our Board worked with its outside advisors to carefully evaluate the proposal.

They determined that this deal represents the best way to maximize value for the company’s stockholders, while enhancing opportunities for customers and employees.

What Happens Next?

First the transaction must be approved by the two companies’ stockholders and certain regulators.

These approvals are expected to take up to twelve months.

In the meantime, we are operating as separate companies and it is business as usual.

Until the deal closes, we should not communicate or coordinate with Halliburton. It is unethical and in some cases illegal to collaborate on bids or otherwise, or discuss proprietary or confidential information with anyone from Halliburton.

How to Talk to Your Team About Change

The company will form an integration team that will carefully plan how to combine our companies in a way that is fair and that ensures a smooth transition for our customers and other stakeholders.

It is likely that some operations will need to be divested or some positions eliminated.

It is too soon to say, however, which operations or positions may be affected.

I understand that this creates some difficult uncertainty. Remember that Baker Hughes was built through countless acquisitions, and many of us joined from acquired companies.

The company will work hard to treat employees fairly and communicate ahead of any changes.

Plans for the combined company’s potential structure will be shared as they are developed.

Conclusion

Remember that there will be no changes to our company until the deal closes.

In the meantime, you can help by focusing on three things:

Stay focused on our single greatest priority: Delivering safe, compliant and reliable service.

Continue to move our business forward: Provide the outstanding service that customers expect of us.

Embrace this opportunity: Baker Hughes and Halliburton resulted from acquisitions.

I look forward to continuing to work with you all and appreciate your commitment to Baker Hughes.
