Wow, this has been a long time coming! I stopped following Nanosonics for a bit -- but from what i understand one of the key reasons for the delay was that biofilm buildup in endoscopes was just a super tricky technical problem. With that seemingly sorted, and the regulators happy, they have a very attractive runway..
Nanosonics is a beast of a business. Love the razor and blade model, fortress level balance sheet, it gushes free cash flow while spending heavily on R&D... what's not to love!!?? Well, for me, it was the price... it just got stoopid in the Covid era and spent the subsequent few years dropping from an ATH of ~$8 all the way to ~$3.
Even now, on a trailing basis, the PE is 120 and the P/S is almost 8x.. Would love to add it to my portfolio again, but I just find it hard to justify at the current price.
Still, the devil is in the detail here. A large chunk of their cost base is associated with growth initiatives -- R&D, geographic expansion, digital transformation (new ERP and manufacturing automation). If you just look at the Trophon business, they get EBITDA margins somewhere around 25% (based on my rough estimates, but that aligns with most mature medical device companies). At scale, you could easily see a future where revenue doubles in the next 5 years and generates a 15-20%net margin (compared with only 7.5% at present).
That would be an EPS of ~20cps, or roughly 5x what it was in FY24. *IF* they achieve that, and shares trade at a PE of 40x in 2030, you'd get a 10% compound annual return. Not terrible. So you could certainly argue shares are reasonably priced. Especially if you look at in on an enterprise value basis, and you account for the very low risk business cash flows.
I just prefer a bigger margin of safety.
