"G4S saga ends as shareholders accept $5.3 billion Allied Universal offer," 16 March 2021

The G4S takeover saga finally came to an end on Tuesday after a majority of the security company’s shareholders accepted a 3.8 billion pound ($5.28 billion) offer from U.S. rival Allied Universal, snubbing hostile Canadian bidder GardaWorld... The merger between G4S and private-equity backed Allied Universal will create the world’s largest private security company, generating more than $18 billion in revenue and employing more than 750,000 security guards and other staff.

... GardaWorld made its interest public in September last year but was faced with repeated rejections from the London-listed company. Allied swooped in last December and its offer of 245 pence per share won over the G4S board, which recommended that shareholders accept.
