In 2007, UK prime minister Gordon Brown came under attack over the sell-off of Actis after it became apparent that the formerly government-owned business had made millions of pounds for its former employees.

[2][14] In July 2023, Actis faced an impending bankruptcy of Energy of Cameroon (Eneo), of which it held a 51% stake and announced its intention to start arbitration if no other solution could be agreed on.

[15] In August 2013, Actis acquired the South African firm Transaction Capital's payment services unit, Paycorp, for US$95 million.

The investment is made through the creation of Honoris United Universities, a network of institutions, including Mancosa and Regent Business School in South Africa.

Commenting on the deal, Actis' Chief Investment Officer stated it was a response after "a number of investors asked us to step in to be part of a solution in mid-2018".

[23] In August 2019, the firm reached final close for the Actis Long Life Infrastructure Fund (ALLIF), raising $1.23 billion in committed capital.

The 15-year, brownfield- and yield-focused, core infrastructure vehicle represents a strategic shift for Actis, which has historically targeted buy-and-build investments via its flagship energy funds.

[25] Despite this shift, the first two deployments for ALLIF were within renewable energy generation - a 110MW PV solar plant in Chile acquired from SunPower in 2018,[26] and a 137MW wind farm in Brazil sold by EDP Renováveis in 2019 for R$ 598 million.

[44] In September 2019, Actis sold Atlantic Energias Renováveis and its operating 642MW wind power portfolio to China General Nuclear (CGN) for a reported figure of c. R$ 4 billion, or roughly six-to-seven times of its initial investment in local currency.

[45] Actis benefited from being one of the early movers into renewable energy generation in Brazil, reaching the status of joint-largest wind operator in the country with platform companies Atlantic and Echoenergia.
