So revenue is up 24%, however EBITDA is down
The decline in EBITDA is due to delay in shipment of devices.

This doesn't hold up to me - how can revenue be up, but EBITDA be down, unless costs are up, either in the cost of good sold or in operating expenses.
Yes if they had shipped those units in June rather than July, EBITDA would be higher (as would revenue even more-so), however revenue is already up 24% despite the delay in shipping, so somewhere costs must be up. I can't see how they can blame a decline in EBITDA on delayed sales, when revenue is already up 24%.
