The business has its origins in the
share registration business of
Lloyds TSB which was bought out from Lloyds by
Advent International, a private equity institution, in 2007. The company was the subject of an
initial public offering in October 2015. In July 2017 it announced the acquisition of the share registration business of
Wells Fargo. On 30 July 2020, the company announced its intention to rebrand as "EQ". In April 2021 Siris Capital made an offer worth £661 million for the company. The transaction was completed on 10 December 2021. Members of the PCS trade union, who were working for MyCSP, a wholly-owned subsidiary of Equiniti, and who administered the pensions of around 1.7 million past and present civil servants, began a strike in July 2025 which lasted for almost five months, running until the end of the company's contract. The strike followed the refusal by MyCSP/Equiniti to recognise the union, and their refusal to negotiate with PCS regarding the transfer of both the work and the staff to
Capita. ==Operations==
