Global management consulting firm. McKinsey entered into a partnership arrangement with Trillian for work at Transnet and Eskom, with Trillian as its "supplier development partner." The Zondo Commission found that McKinsey agreed to subcontract to Trillian despite Trillian performing little or no substantive work — effectively legitimising the extraction of fees. McKinsey was paid approximately R1 billion combined by Transnet and Eskom. Subsequently agreed to repay R650 million. Also fined by UK and US regulators over its South African state capture involvement.
