On 31st March 2004, the Mayflower Group was put into administration. On 17th May 2004, the Plaxton coach business was sold to its management and returned to its separate Plaxton identity (TransBus had been in the process of eradicating the traditional company names from the vehicles). Four days later, on 21st May 2004, the remaining part of the business (Alexander and Dennis) was bought by independent businessmen, one of whom was Brian Souter, although this acquisition was kept separate from the Stagecoach bus and train operation. The new company quickly adopted the trading name Alexander Dennis Ltd (ADL). The sale did not include the former Alexander Belfast plant, which later closed down. Stagecoach remains a major customer of Alexander-Dennis.
