A public company must file a current report on Form 8-K with the SEC within four business days of completing a significant acquisition or disposition of assets, under Item 2.01 of the report. The acquired company sometimes files one too, when the deal makes it a subsidiary of the buyer.
Every fact on this page is taken from one of those filings and linked to it: which company acquired which, the date the filing gives for completion, and the price when the filing states one in dollars, shown next to the sentence that states it. A filing states what was bought and on what terms; it rarely states why, and neither does this page.
