United Biscuits (UB) was formed in 1948 by a merger of two Scottish family businesses: McVitie & Price and MacFarlane Lang.

[4] In 1962, William Crawford & Sons, a business founded in Leith, Edinburgh in 1813 which was best known for its shortbread, was acquired by United Biscuits for £6 million.

[12] United Biscuits was de-listed from the London Stock Exchange and acquired in May 2000 by Finalrealm, a consortium of financial investors, as well as Nabisco Holdings Corporation.

As part of the transaction, UB acquired Nabisco's European businesses[13] and divested several parts of its international business in Scandinavia, continental Europe, Asia (Keebler Malaysia and Singapore), several brands including TUC and 70% shareholding in Fazer Keksit (Biscuit) in Finland to Groupe Danone and Far East (China, Hong Kong, and Taiwan) to Nabisco.

[16] In July 2006, the company sold its Southern European biscuits business to Kraft Foods, which in turn left the owner syndicate.

[21] On 3 November 2014, private equity funds managed by Blackstone and PAI Partners announced the sale of United Biscuits to Yıldız Holding.
