Pharma internal expenses fraction total business relies acquiring?

I can’t determine what you mean by “Pharma internal expenses fraction total business relies acquiring” from the current wording. It looks like you may be asking for a specific metric related to how much of a pharma company’s total business is spent on “internal expenses” (possibly R&D, SG&A, or internal costs) as a fraction of total expenses, or how that fraction affects ability to fund acquisitions.

If you clarify one item, I can give a precise answer:

1) What exactly is “internal expenses” in your question?
- R&D only, SG&A, “operating expenses,” or something else?

2) Which “pharma” scope do you mean?
- A specific company (tell me the name), or pharma industry in general?

3) What do you mean by “relies acquiring”?
- Does the question mean “funding acquisitions,” “business depends on acquisitions,” or something like “relies on acquired products/technologies”?

Reply with those details (even short answers), and I’ll compute/translate the metric using the provided context you want (financial statements, filings, or a particular dataset).
