Tata Consultancy Services is buying MHP, the management and IT consultancy Porsche has owned for years, for €320m, and signing a five-year engagement with the carmaker worth €1.25bn on top of it.

The two halves are what make the deal worth reading, because Porsche is simultaneously disposing of an asset and committing to buy back a version of what it produced from a firm rebuilding itself around deployed AI engineers.

MHP is a substantial business rather than a captive department. It employs about 4,500 people, generated €742mn of revenue in 2025, and serves more than 300 clients across automotive and industrial sectors, with practices spanning SAP implementation, manufacturing digitalisation, and software-defined mobility.

All 4,500 employees move to TCS when the transaction closes, which both companies expect within three to four months. Porsche will remain a customer rather than an owner, and TCS will set up a dedicated centre of excellence for the carmaker.

“This partnership brings together TCS’ capabilities in AI, engineering, technology and business transformation with MHP’s strong automotive consulting expertise,” said K Krithivasan, the Indian firm’s chief executive. Porsche’s chief executive Michael Leiters framed it as combining the carmaker’s domain knowledge with outside digital capability to strengthen its innovative power.
