Invensys Ltd. was a multinational engineering and information technology company headquartered in London, United Kingdom. It was formed in 1999 through the merger of BTR plc and Siebe plc. It had offices in more than 50 countries and its products were sold in around 180 countries. The company was founded on 1 April 1920 as Siebe Gorman & Company Ltd and continued through various name changes registered at Companies House from that date. In January 2014 the company was taken over by the French multinational Schneider Electric for a total consideration of $5.5 billion. Schneider phased out the "Invensys" name in favour of its own. Invensys lines of business were grouped into four segments: Software, Industrial Automation, Energy Controls and Appliance. Its brands included Avantis, Eurotherm, Foxboro, IMServ, InFusion, Triconex, SimSci, Skelta, Wonderware, Drayton, Eberle, Eliwell. History Invensys was formed through the merger of BTR plc and Siebe plc in 1999. From 1999 to 2004, it underwent a major restructuring programme to cut its costs as falling sales and large debts had led to the danger of its going bankrupt. A major disposal programme combined with a £2.7bn debt restructuring in 2004 saved it from collapse. During that time it bought and sold The Baan Corporation. In March 2011, Wayne Edmunds, who had been chief financial officer since 2009, was appointed Chief Executive, replacing Ulf Henriksson. According to The Financial Times, Henriksson, who had been Chief Executive since 2005, had had differences with chairman Nigel Rudd over running the company, in spite of the return to financial health under Henriksson. During 2011 and early 2012 the share price fell nearly 50%, in part due to delays costing £40 million in producing control and safety systems for eight Chinese nuclear reactors. In July 2013 it was announced that Invensys was to be taken over by the French multinational Schneider Electric for a total consideration of £3.4 billion. The takeover was completed on 17 January 2014. Operations Invensys was organised into four main segments: Software, Industrial Automation, Energy Controls and Appliance.
