I'll second that @nerdag
Nanosonics is an excellent business in my view, but the market price had baked in a huge amount of growth. A drop in revenue, even a small one, is not going to be received well when you are trading at those multiples.
Yes, a new revenue stream, a reduced development expense and a huge cash pile requires a more nuanced view, but I think the point generally stands.
There will be a point at which the price makes sense. But I've yet to do the work to figure out where that might be.
