Two stories which tell you what the market thinks...
This one tells you that the combined company still doesn't have the capability to compete with the upstarts:

This one tells you pretty much the same plus pointing out why ten billion won't be enough to convince the shareholders :

I think the shareholders won't take it and even if they do, due diligence from atos should reveal that what they think they are buying (ie the company dxc talks about being) doesn't actually exist.
I think it will fall through, which isn't bad news because the market also thinks that Salvino is on track to get dxc at least to stable if not growth immediately. That would be an impressive win given the starting point.
