Methodology

This edition covers eight days, September 24 to October 1, 2026. A deal counts if it has a US target or a US buyer and the buyer takes control; minority and growth investments, a joint venture with no controlling partner, and a REIT takeover the buyer described as acquiring a portfolio of shopping centers were left out. Dates and values come from each company's own release or SEC filing, so later law firm announcements and closings do not move a deal into the window. That rule removed six deals that surfaced as this week's news but were first announced between July and September 22. A firm is credited only where a release or the firm's own page names it as counsel for one side. The $20.5 billion total uses the headline value each company states, enterprise value where one is given, and leaves out earn-outs, contingent value rights, press-reported valuations and the SPAC combination.
