Mr Lauda wanted put in a bid to buy the airline back after hearing about the grounding.
IAG will retain about 740 former Niki staff and will run the airline as a new subsidiary of its budget carrier Vueling.
The assets will be inclusive of 15 planes along with slots in airports such as Vienna, Munich and Palma.
The deal has to be approved by European authorities.
