Bouygues S.A. is a French engineering group headquartered in the 8th arrondissement of Paris, France. Bouygues is listed on the Euronext Paris exchange and is a blue chip in the CAC 40 stock market index. The group specialises in construction, real estate development, media, and telecommunications.
The company was founded in 1952 by Francis Bouygues and quickly secured construction opportunities from the French state, leading to it being involved in social housing and the French motorway system. It listed on the Paris Stock Exchange in 1970 and started to diversify and internationalise during the years thereafter. During the 1980s, Bouygues acquired Screg, Sacer, and Colas. On 29 May 1996, it launched Bouygues Télécom. In 2006, the company acquired 23.26 percent of the French conglomerate Alstom. Since 1989, the company has been led by Francis Bouygues's son, Martin Bouygues, while Martin's older brother, Olivier Bouygues, is a board member.Wikipedia
