Acquisitions, divestitures, and spinoffs

This is our unofficial directory of 157 acquisitions -- and 30 divestitures and spinoffs -- by HP, HP Inc, and Hewlett Packard Enterprise. (Minority stakes are not included.) 
The most recent events are highlighted. Updated September 1, 2017.

Additions to the directory are suggested by HPAA members and verified via news articles or annual reports.

Other sources of information on HP's acquisitions and divestitures:

  • HP. The original press releases announcing major acquisitions since 2000 are available on HP's Investor Relations site. (HP's list does not include minor acquisitions, divestitures, product line acquisitions, development team acquisitions, or acquisitions of customer IT departments through outsourcing contracts.) 

  • Wikipedia. Links to news articles and press releases covering many acquisitions are provided in a table on the Wikipedia. (Note: Wikipedia articles -- since they can be written, rewritten, or edited by anyone -- may not be accurate or current, often change dramatically over time, may not cover all aspects of the topic consistently, and may not be written from a neutral point of view.)

Dates given are generally the date of closure, not the date of announcement.

To add or correct a listing, please email.

There are independent alumni networks for many of the acquired and successor companies. For our directory of networks, groups, and websites for current and former Hewlett-Packard people around the world: Networking Directory.
