G4S plc (formerly Group 4 Securicor) (LSE: GFS, OMX: G4S) is a British multinational security services company headquartered in Crawley, United Kingdom. It is the world's largest security company measured by revenues and has operations in around 125 countries. With over 657,000 employees, it is the world's third-largest private sector employer (after Wal-Mart Stores and Foxconn). G4S was founded in 2004 by the merger of the UK-based Securicor plc with the Denmark-based Group 4 Falck.
In 2006, 2007 and 2008 G4S was the subject of a global campaign by union workers alleging that its subsidiaries undermine labour and human rights standards. Some of these groups were organised under the banner of the SEIU-funded Focus on Group 4 Securicor. This group supported protests at Group 4 Securicor's annual general meeting in London in 2005 and again in 2006.
The 2006 US State Department Report on Human rights in Indonesia released in March 2006 featured the on-going dispute in Jakarta with Group4/Securicor. In July 2006 the Indonesian Securicor workers had a substantial win – but the campaigners continue to support other Group 4 Securicor workers. The company disputed these claims and pointed to its strong relationships with unions around the world, including the GMB in Britain.
In March 2008, it was announced that G4S were taking over Scottish Rock Steady Group – who steward at major sporting and music events mostly in the UK. Rock Steady events have included Live8 concerts in London, Scottish FA Cup Final & the Download Festival. In April 2008, G4S acquired RONCO Consulting Corporation, one of the world’s premier humanitarian and commercial mine action, ordnance disposal and security companies.
In May 2008, G4S acquired ArmorGroup International. Also in May 2008 G4S plc completed its £355 million acquisition of Global Solutions Limited. In December 2008 G4S and UNI, the global union, announced the launch of an Ethical Employment Partnership, which will drive improvements in standards across the global security industry. Also in December 2008, G4S and the SEIU reached an agreement to end their long dispute and establish a framework to work together in the interest of employees. In 2009, G4S continued to acquire companies: Secura Monde International Limited and Shiremoor International Engineering Limited, together, the UK’s leading specialist banknote and high security technical and commercial advisory companies; All Star International, one of the premier facilities management and base operations support companies providing services to the US Government; Adesta, US-based provider of integrated security systems and communication systems; and Hill & Associates Consultants Limited, Asia’s leading provider of specialist risk-mitigation consulting services.
In 2008, G4S also acquired Touchcom, Inc. for US$23 million. Touchcom, Inc. is located in the Burlington/Bedford, Massachusetts area. The rebranding of Touchcom, Inc. to G4S was completed by 1 January 2012.
In April 2011 G4S acquired Guidance Monitoring, an international designer and manufacturer of electronic monitoring technologies, including hardware and software used for offender monitoring and tracking.
In December 2011 G4S acquired the assets of Chubb Emergency Response, a large key holding company in the UK. The deal was finalised on 17th December 2011. G4S are now integrating the Chubb business into their existing key holding and response service.
G4S announced in late August 2012 that it would be selling its Pakistan division, Wackenhut Pakistan Limited, to its chairman Ikram Sehgal.
