Current SP appreciation, page-135

Thanks for the quality of your contributions.
For those who have arrived recently,
I was particularly impressed with this one:
https://hotcopper.com.au/threads/par-the-billion-dollar-timeline.4960102/
As it happens PAR have surpassed my expectations to this point, i was thinking (around August) $2.50 would have been a good return till now.
My main concerns now might seem overblown but i think they need careful evaluation
1. what is the exposure to the source of the product from their supplier.
Can anyone shed any light on that, how secure is that?
2. Is the market that big, are the PAR patents effective for excluding other delivery channels for the off-patent original pharmaceutical?
I guess this is easy to dismiss, but does anyone KNOW?
