This topic was covered in the now-closed Tandem Alumni Forum (operated by former Tandem employees, not by the HPAA.)

HPInc is the legal successor to the companies acquired by Compaq. Stockholder information and contact instructions: HPInc Investor Relations Site

Compare the date when you first acquired Tandem stock with the dates in the left-hand column. If you later acquired Compaq shares while a Compaq employee, those batches of stock should be tracked separately -- see our Compaq Stock Decoder.

Note: Stock plan administrators and stock brokerages vary (sometimes dramatically) in how they make gain/loss and cost basis calculations and in what they report to the IRS. Each of the 236 NYSE member firms (and others around the world) is expected to read SEC filings, analyze Corporate Action Notices, and update the records they maintain on behalf of their clients.

The black entries in the table below are from the online system available to customers of one broker, Charles Schwab & Co. The HPAA member who contributed this table did not hold this stock before 1987.

The blue entries were developed from reports by members of the Tandem Alumni Forum and contemporaneous news stories. Given Tandem's high growth rate, there must have been earlier stock splits. (EDGAR, the SEC's searchable online database, includes SEC filings from some companies back to 1994 and from all companies only back to May 1996.)

This table only covers HP/HPE stock events through 04/30/2019. See our HP Stock Decoder for subsequent stock events.
