Assuming these Nautilus models will mostly be delivered within the next twelve months; with 5000 units, that means this is already going to be more than 5% of the entire annual production in unit terms (the estimated production was around 70,000 pieces for 2025, 2026 will probably be similar +/- a few percent) and around 10-12% of the entire revenue.
So, it's already significant! Especially if they deliver nearly all of them in the next 8-12 months!
