Bad news
SInce the company starts getting overvalued (market price jumps after announcements) by the suitor, they end up paying a bigger price than originally intended, and end up charging the consumers to recoup this costs and justify it to their shareholders.
Mega takeovers and mergers are never in the customers and consumers inetrests.
It only fatten the moneymen (ie buyers, shareholders and bankers). Their only interest is how to milk the max out of any venture.
And end up with poorer service standards.
