The PSA Group (), legally known as Peugeot S.A. (Peugeot Société Anonyme, trading as Groupe PSA; formerly known as PSA Peugeot Citroën from 1991 to 2016) was a French multinational automotive manufacturing company which produced automobiles and motorcycles under the Peugeot, Citroën, DS, Opel and Vauxhall brands. On 18 December 2019, PSA and Fiat Chrysler Automobiles (FCA) announced that they had agreed to the terms of a binding $50 billion merger. On 16 July 2020, both companies announced the new name for their merged operations, Stellantis. The deal closed on 16 January 2021. Stellantis is now the third largest automotive manufacturing company, behind only Volkswagen and Toyota. Peugeot was the largest PSA brand. PSA was listed on the Euronext Paris stock exchange and was a constituent of the CAC 40 index. Beginning in 2016, PSA began to outline a strategy which entailed the rapid expansion of the company, through both geographic expansion and acquisitions of other car companies. PSA has announced plans to enter the Indian, American, Canadian, South East Asian, and other markets in the coming years. Headquartered in Rueil-Malmaison, PSA, with sales of 3.88 million units in 2018, was the third-largest Europe-based automaker, just a fraction behind Renault. In 2019, Groupe PSA was the ninth largest automaker in the world, after Volkswagen, Toyota, the Renault–Nissan–Mitsubishi Alliance, General Motors, Hyundai Motor Group, Ford Motor Company, Honda, and Fiat Chrysler Automobiles. History Citroën acquisition In December 1974 Peugeot S.A. acquired a 38.2% share of Citroën. On 9 April 1976 they increased their stake of the then bankrupt company to 89.95%, thus creating the PSA Group (where PSA is short for Peugeot Société Anonyme), becoming PSA Peugeot Citroën. Since Citroën had two successful new designs in the market at this time (the GS and CX) and Peugeot was typically prudent in its own finances, the PSA venture was a financial success from 1976 to 1979. Chrysler Europe acquisition In late 1978, PSA purchased the failing Chrysler Europe (which had been Rootes and Simca) from the troubled US parent firm for a nominal US$1.00, plus assumption of outstanding debt, leading to losses for the consortium from 1980 to 1985. Further investment was required because PSA decided to create a new brand for the entity for the disparate French and British models, based on the Talbot sports car last seen in the 1950s. From then on, the whole Chrysler/Simca range was sold under
