The article above, claims that a quarter of DXC's earnings come from public sector (half of that from US public sector). I suspect they will keep it, but I read somewhere that from a financial perspective they are breaking out the figures (making it more attractive to purchase).
I suppose it depends on whether US gov is spending more money, the reason (lack of) that made CSC push away their US public sector business.
