Well firstly they have committed to the ASX that they will complete a capital raise that will fund the company through the next 12 months, that is a very big deal! At approximately $1.5 M / month operating expenses that's already $18 M, I think they will probably raise $20 M + which means an insto or two is involved, hopefully US based and with some real market clout. That will allow RSH to execute their current US commercial plans, bring on more hospitals, more patients, increased revenues, sell more wheezos towards break even late 2024.
Hopefully with the right instos and investor strategy this gets the SP really moving in the right direction on the basis of real tangible progress and success. As others have pointed out the market is huge, even in the hospital setting with medicare and private insurers picking up the bill.
Imagine in a couple of years when this is in the mainstream and the average family is buying it for their kid with asthma - what is the sales potential of that market?
So who is investing $18 - $20 M capital in a company they believe is going to fail ?
