Corporate mergers are, in reality, the sorts of things which never happen quickly. Companies may well spend years appraising each other’s position in the market, assets, potential and value before engaging in talks to take over one another. Once those discussions are taking place, there’s no guarantee that they’ll even come to anything, and if they do, due diligence could put the kibosh on the whole thing before it gets anywhere. If that doesn’t get you, then competition and regulatory bodies might well do. Needless to say then, two huge companies coming together is a tricky business.
