Greencore Group plc is a food company in Ireland. It was established by the Irish government in 1991, when Irish Sugar was privatised, but today Greencore's products are mainly convenience foods, not only in Ireland but also in the United Kingdom. A major supplier to British and Irish supermarkets, Greencore is the largest sandwich manufacturer in the world. It is listed on the London Stock Exchange. History The company was established in 1926 in Carlow as a private enterprise known as the Irish Sugar Manufacturing Company, Limited. The Sugar Manufacture Act, 1933 was passed to promote self-sufficiency in sugar manufacture; this Act was brought on by a crisis in the industry and resulted in the nationalisation of sugar manufacture. Factories were built in Mallow, Thurles and Tuam, and the company became Cómhlucht Siúicre Éireann, Teoranta, the Irish for Irish Sugar Company, Limited. When run by Michael Joe Costello, Irish Sugar introduced the first electronic computer into Ireland in 1957, buying it from Dora Metcalf. The Thurles and Tuam factories were closed in the early 1980s after a rationalisation became necessary, and the company decided to concentrate manufacture at its Carlow and Mallow factories. In February 1990, the then managing director, Chris Comerford, was found to have received £9 million when the company acquired the 49% shareholding in a subsidiary that it did not already own. Comerford resigned but four years of litigation between the company and Comerford followed. The Sugar Act, 1991 privatised the entity and it became Greencore at that time. The Act was passed as the company had diversified beyond being a sugar-manufacturing company into other food products. That year 55% of the group was listed on the Irish Stock Exchange, and over the years since additional placements have led to almost 100% of the shares being in private hands. However, the Irish Government retains a special share, with a face value of EUR 1.26, in order to prevent the Irish sugar quota being sold without its consent. In 2005 the company announced that it would close its factory in Carlow, ceasing production on 11 March. In March 2006 it was announced that the last remaining factory would close in Mallow, and this closure occurred on 12 May. The reason indicated for these closures has been the reform of European Union policies on sugar which reduced the quotas and subsidies available and therefore making its manufacture unprofitable in
