First off, I'm not thinking about it too much at this point in time because I highly doubt this deal will go through. An international takeover is certainly something that is not likely to go well with Japanese regulators.
On the chance the deal does go through though, I'm not particularly bullish on it. This is a gigantic acquisition, more than half the size of Couche-Tard itself, and has a lot of moving parts and difficulties. Smaller tuck-in acquisitions are often beneficial, but large-scale ones like this tend to have their bumps in the road.
However, I'll cross that bridge in terms of analysis when we get there. For now, I don't think it's going to be accepted, and if it is, regulatory hurdles will come into play.
