Tower said it anticipates its underlying net profit after tax including big events to be about $26m, up from a range of $21m-$25m for the September 30 year.
The insurer said underlying net profit excluding large events ($14m after tax) was expected to be about $40m, above the previously advised range of $35.4m to $39.4m.
The profit boost followed a surge in gross written premiums (GWP), reflecting rate increases and organic growth from existing and new customers, the company said.
Tower said other factors were stronger retention, and disciplined management of claims and operating costs.
Unaudited GWP had increased 13 per cent to $457m during the 2022 financial year compared to the prior year and customer numbers grew 4 per cent to 317,000.
