On completion in early April, the deal will create one of the world's top IT services companies with US$26 billion in annual revenues and nearly 6000 clients in over 70 countries.
"With a mission of leading clients on their digital transformation journeys, DXC Technology will be recognised globally as a force multiplier, enabling clients to seize the opportunities presented by today's rapidly changing technologies," said CSC chairman, president and chief executive, Mike Lawrie.
Lawrie will become chairman, president and chief executive of DXC Technology when the merger is completed.
Until the completion of the merger, CSC and HPE ES will operate as separate organisations.
All necessary regulatory clearances for the merger have been granted, the companies have announced.
HPE Enterprise Services came about as a result of the then HP's 2008 acquisition of EDS.
In 2015, the "old" CSC split into two companies. The government services business was merged with SRA to form CSRA. The "new" CSC went on to acquire other companies, including Australia's UXC, before the merger with HPE Enterprise Systems was announced.
