Well FWIW one of Macquarie's analysts has said they expect 11% compound growth in CI unit sales to justify their valuation, through to 2033. (Haven't seen any other compound growth numbers). But COH has just had 4% growth in half 2 by my numbers, and is expecting 10% approx next year - although this year COH guided to a 12.5% midpoint, and got 9%.

So if other analysts are similar we might be looking at downgrades due to lower growth expectations.

For the last 11 years we have averaged 6.1% CI unit growth. So if analysts go back to there, that will be a big decrease in growth rate expectations. The most COH has had in average growth rate is about 12% for 3 year stretches.

So in 2033 - if we have an 11% compound growth rate, there will be sales of 125k units. If the CGR stays at 6.1% we get 80k units. So roughly only 60% of what Mac bank has factored in for the future.

I wonder if single sided implants are a bit unlikely to skyrocket - why would you go for an operation etc if you could still hear OK in one ear.
