CSC said Monday holders of approximately 84.92 percent of outstanding shares in the company voted in favor of the transaction.
HPE and CSC announced the proposed merger in May 2016 in a push to establish a global information technology services company that is expected to generate $26 billion in annual revenue.
CSC will disclose the final voting results in a Form 8-K document the company will file with the Securities and Exchange Commission.
The decision of CSC shareholders on the proposed merger came two weeks after the future combined entity named members of its senior management team as well as vice presidents and directors across its operating and corporate groups.
The company that will form out the merger will operate as DXC Technology upon the deal’s closure on April 3.
