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

HPInc is the overall legal successor to Hewlett-Packard and to companies acquired by Hewlett-Packard before Nov 1, 2015 – Compaq, EDS, etc. – regardless of whether a business unit ended up in HPInc 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, HPInc 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.

Service at HP predecessor companies.

Of HPInc's many predecessor companies, only HP and DEC ever had US retiree healthcare programs -- setting aside money over the years in dedicated trust funds. Employees of other acquisitions did not get credit under HP's long-service retiree healthcare program for service at the predecessor -- but generally did get service credit for other benefits. https://www.hpalumni.org/health

Of HPInc's many predecessor companies, only HP, DEC, and EDS ever had US pension plans -- setting aside money over the years in dedicated trust funds. Employees of other acquisitions did not get credit under HP's pension programs for service at the predecessor -- but generally did get service credit for other benefits. https://www.hpalumni.org/RetirementPlans

EDS alumni report that their original EDS hire date is mentioned in their HR records at HP Inc, HPE, DXC, and Peraton.

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 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.)

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.
