the other point in addition to moat, patent tech, high margins; is its in a recession resistant industry l. even pandemic resistant still seen 30%+ yoy growth during covid! when its customers are hospitals /surgeons
the demand for the product is also key for growth as much as growing sales teams
globally populations are both growing and aging. rhis places enormous pressures on public and private health spending to treat more people for the same cost as when there was less people or less money. having worked in analytics, they are using analytics in hospital supply chains to spot where some doctors are using more expensive medical devices then their peers and looking to standardise care; ie meaning a certain level of healthcare for more people.
pnv is cutting edge in wound care offering as good or better outcomes then biggest competitors charging twice the price
id even hazard a guess the lower costs make it easier to get it approved for purchase internally, below internal cost limuts for treatments; the finance side of hospitals would be steering surgeons to use the product; its got a lot going for it regarding both the supply side and demand side of the market
