Using her father's redundancy money, and working with her brother Sir Brian Souter and her husband Robin Gloag, Gloag established the Stagecoach Group in 1980, running buses from Dundee to London. Expansion continued and in the early 1990s, Stagecoach acquired National Bus Company operations in Cumberland, Hampshire, East Midlands, Ribble, Southdown and the United Counties. Stagecoach bought further bus operations in Scotland, Newcastle and London, with Manchester being added a few years later. In 1993.
On 29 November 2013 Ann Gloag took ownership of Kent International Airport, also known as Manston Airport for the sum of £1. Gloag's co-director is Pauline Bradley, a corporate lawyer and former head of joint ventures at Bank of Scotland, described by the Scottish Herald as "one of Scotland's most powerful women".
Despite assurances to staff regarding long term investment in the airport management announced a consultation on closure in April 2014. Uncertainty about the airport's future led flight operators who were using Manston to leave, notably KLM who ran a twice daily service to Amsterdam Schiphol. A number of bids were forthcoming during the consultation period to buy and run the airport, but on 15 May 2014 Manston was closed with the loss of 144 jobs in the airport and an unknown number in the surrounding area. Ann Gloag did not appear publicly or give a reason for the airports closure or her refusal to sell. The trade union Unite said it would challenge the way the consultation on closure was conducted. Sir Roger Gale, Member of Parliament for Thanet North described Gloag's actions as an act of "corporate vandalism". Gale and members of a number of pressure groups including Save Manston and Why Not Manston continue to campaign for the reopening of the airport and have opposed alternative uses. The Prime Minister of the UK, David Cameron, made a public statement in the Houses of Parliament in support of Manston on 14 May 2014.
Gloag has owned Beaufort Castle near Inverness since 1995, and Kinfauns Castle, near Perth since 2004. She has attempted to block off private access at Kinfauns in a high-profile case. On 12 June 2007 she was successful in gaining a court ruling that she was legally entitled to bar the public from a swath of woodland in the grounds of Kinfauns Castle.
