Acquisitions, divestitures, and spinoffs -- with links for former employees. (Updated Aug 12, 2025)
This is the HPAA's unofficial directory of 169 acquisitions -- and 30 divestitures and spinoffs -- by HP and HPE since 1958. (Minority stakes are not included, nor are acquisitions made by EDS.)
The most recent events are highlighted.
Stock. If you were ever an HP shareholder, you may now have shares of HPQ, HPE, Keysight, and/or Agilent in different accounts. If ever an HPE shareholder, you may now have shares of DXC and may not have received cash payouts for MFGP and PRSP. Find it all and estimate your current cost basis: HP/HPE-Related Stocks
If you had stock in a company that HP or HPE acquired or merged with, check for cash payout or new shares: Autonomy (AUTNF) Compaq (CPQ) DEC (DEC) EDS (EDS) Juniper (JNPR) Micro Focus (MFGP) Perspecta (PRSP) Plantronics (POLY) Tandem (TDM) Other Predecessor Companies
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 table of original press releases announcing major acquisitions since 2000 is no longer available on HP's Investor Relations site. We have a copy as of May 15, 2018. Go to the independent non-profit Internet Archive to use the links on the page, which still work: "Mergers & acquisitions announcements". (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. There is a Wikipedia table of 116 HP acquisitions. It is in chronological order, has links to news articles and press releases, and gives acquisition costs if known. However, it is incomplete -- for example, there are no entries for 2018 through 2020. Does not mention the divestitures. (Note: Wikipedia is very useful. However, the articles can be written, rewritten, or edited by anyone -- and therefore 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.
HP Inc is the overall legal successor to Hewlett-Packard and to companies acquired by Hewlett-Packard before Nov 1, 2015 such as Compaq, DEC, EDS, Tandem, etc. -- regardless of whether a business unit ended up in HP Inc or HPE. For employees of HP -- and predecessor companies -- who left before the HPInc/HPE separation, responsibility for any health or retirement benefits varies from country to country. For the US, HP Inc has responsibility. For Canada and UK, HPE has responsibility. In many countries, plans were split between HP Inc and HPE. See: Where are my benefits?
Hewlett Packard Enterprise (HPE) is the overall legal successor to companies acquired by HPE such as Cray, Juniper, Nimble, etc.
Worldwide employment verification and experience letters for Hewlett-Packard, Hewlett Packard Enterprise, and related companies. Employment and Experience Verification
Product successor -- the company that appears to currently have the majority of the acquired company's products. For example, the notation "(HPE to Micro Focus)" indicates that product responsibility most likely moved from HP to HPE to Micro Focus as a result of the Hewlett-Packard breakup.
