Alexander Dennis (formerly known as TransBus International) is a British bus building company based in Scotland. The largest bus and coach manufacturer in the United Kingdom, Alexander Dennis is one of the world’s fastest-growing bus builders, with manufacturing plants and partnerships in Canada, China, Europe, Malaysia, New Zealand and the United States.
In 2013, Alexander Dennis had a 34% market share in the United Kingdom. As at April 2014, Brian Souter and Ann Gloag collectively held a 55% shareholding.
Alexander Dennis was formed as TransBus International on 1 January 2001, when Mayflower Corporation (owner of Dennis and Alexander) merged with Henlys Group (owner of Plaxton).
TransBus International inherited a number of factories around the United Kingdom from all three merged companies: the former Alexander factories in Falkirk, Scotland and Belfast, Northern Ireland, the former Plaxton factories in Anston and Scarborough, the former Northern Counties factory in Wigan, and the Dennis factory in Guildford.
