History
Formerly an operating division of Suez, the company was spun out as a stand-alone entity as part of the merger to form GDF Suez (now Engie) on 22 July 2008. Engie remained the largest shareholder of the company with a 35% stake. On the stock market, Suez Environnement's share price increased 40% in value on its first day.
In April 2014, Suez Environnement signed three major water treatment contracts in India worth 61 million euros. In July 2015, the group Suez Environnement simplified its name to become Suez, after the group GDF-Suez changed its name to Engie, leaving the name Suez available again. In September 2015, Suez acquired Sembcorp's 40% stake in the companies' common joint-venture to provide water treatment and waste management in Australia.
On 1 October 2017 Suez bought the Water & Process Technologies unit from GE Power for 3.4 billion dollars and formed a new business unit called Suez Water Technologies & Solutions. Suez shares are listed on the Euronext exchanges in Paris and Brussels.
In 2022, the consulting firm Bioentech, founded in partnership with INRAE, was placed into compulsory liquidation. It was subsequently acquired in its entirety by the Suez Group.
Water Technologies and Solutions “WTS” subsidiary
WTS was formed as a 70%-30% joint venture between Suez and CDPQ in 2017, before becoming a subsidiary of Veolia following the Veolia–Suez merger in 2022, with CDPQ keeping its 30% minority stake. In FY2024, WTS achieved revenues of €3.3bn ($3.6bn) and EBITDA of €472M ($511M).
In 2021 this subsidiary was sold to Veolia along with other Suez entities
On 14 May 2019 Bertrand Camus was appointed as chief executive officer of Suez.
On 1 February 2022 Suez was acquired by a consortium of shareholders, and a new CEO, Sabrina Soussan, was appointed.
As of 1 August Sabrina Soussan was appointed chairman and chief executive officer of Suez.
