FWIW, I suspect you are barking up the wrong tree. Companies generally don't break out subs in that sort of detail so I'm thinking the question isn't a finance / accounting question. Plus, foreign currency translation under GAAP tends to distort what is really going on anyway.
My guess is the question is more of a soft - type question about integrating different cultures, or possibly a question regarding pricing and deriving a demand curve - though getting that data will be tough too.
If you are absolutely convinced this requires financial data, call the company and ask for the CFO (not investor relations). Claim you are an analyst for some sell side firm (make up a name for one). Say it is a start up boutique targeting clients who are interested in biotech and growth health care stocks. This may well get his attention because Johnny John is a slow grower who covets a growth stock multiple and desperately wants to be perceived as a growth stock. It might be enough to get him on the phone. Trouble is, you have to know exactly what info you need because you will probably get a couple minutes with him tops.
Like I said, I think the question doesn't require such data. No B-school would expect a student to call the company and use subterfuge to get some data that hasn't been publicly disclosed.
