Concerns re: costs up and delayed revenue

I note Class' website is advertising free software until 1/1/19 for new users. I strongly support an aggressive strategy to gain market share whilst your customers are still playing catch-up technically .... but I wonder if the market has factored in this delay in revenue + increase in costs and how long it may continue until EBITDA starts increasing again (my reading of the 1H results/forecast was for flat EBITDA in 2H). With continued discounting and increasing head count/marketing, maybe FY19 EBITDA won't increase either?

I like Class as a business a lot - but concerned that costs up coupled with delayed revenue may put downward pressure on the share price and maybe a big fall when their results are published.

Others thoughts?
