Halliburton has agreed to acquire oilfield services provider Baker Hughes in a stock and cash transaction, valued at $34.6bn.
Baker Hughes, which employs 61,000 people in over 80 countries, helps customers identify, evaluate, drill, produce, transport and process hydrocarbon resources.
The transaction combines two suites of products and services into a new offering for oil and natural gas customers.
The combined company’s 2013 revenue was $51.8bn with operations in over 80 countries globally.
After completion of the transaction, Baker Hughes stockholders will hold about 36% of the combined company, which will maintain the Halliburton name with headquarters in Houston, Texas.
Halliburton chairman and chief executive Dave Lesar will lead the combined company, which is estimated to save about $2bn per year in costs.
