Really quite silly for them to buy DXC. DXC customers are fleeing as fast as commercial contracts allow due to poor service and high prices.
All ATOS has to do is put in a better tender as they come up for renewal and they'll get the job without a ton of capex. And I can say as being on the recieving end of IT support now by ATOS, previously by DXC that they will win easily on every single metric over DXC.
