The milestone payments are broken up, some are regulatory and some are sales based.
it's close to 1 billion total possible I believe when US and EU are combined, but the approval milestones will be a fraction of that. They also got an advance in place of one of the later EU ones some time ago.
There is also some language that's been shared on other boards that limits the number of milestones they can collect at one time, at least, the sales based ones, to, I think, 1 per year. The additional earned milestones in that year would then be paid later after they pay the largest earned one first. This is presumably to protect Chiesi's bank account in case it gains instant traction in the market.
This was my understanding.
