Hewlett-Packard's board has approved its previously announced split into two separate listed entities - computers and printers, and corporate hardware and services.
Hewlett-Packard said on Thursday it expected its split into Hewlett Packard Enterprise and HP to be completed on November 1.
A day later, Hewlett Packard Enterprise, comprising the corporate hardware and service business, will start trading on the New York Stock Exchange under the ticker symbol "HPE".
Hewlett-Packard, which will be renamed HP and comprise the computers and printers business, will continue to trade under its current ticker symbol.
Hewlett-Packard shareholders will get one share of Hewlett Packard Enterprise for each share held as of October 21.
The tax-free distribution will be on a pro-rata basis, the 75-year-old company said.
Hewlett-Packard announced the split in October 2014 after years of struggling to adjust to the post-PC computing era.
It said it expected Hewlett Packard Enterprise to start trading on a "when issued" basis on or around October 19 under the ticker symbol "HPE WI".
Hewlett-Packard shares were unchanged at US$25.61 (A$36.43) in premarket trading on Thursday.
Up to Wednesday's close, the stock had fallen about 27 percent since October 3, the last trading day before the company announced plans to split.
