What is the infinitive of paranee, and why don't we use parantaa here?
The verb is parata (verb type 4), which means 'to get better' or 'to improve' on its own (intransitive). If you used parantaa, it would mean someone is actively improving or curing something else (transitive). Since the profitability is improving on its own, parata is the correct choice. You could also use its common synonym parantua (parantuu).
