Effective pricing measures and continued focus on operational efficiency
resulted in a significant improvement in the insurance service result. Profit
for the pension business was negatively impacted by the termination of the
implementation of the core IT system. Results from the investment portfolios
contributed to an annualised return on equity of 29.6 per cent. Gjensidige's
capital position is strong.

-Our strong growth momentum continued in the quarter. The insurance service
result increased substantially, driven by the continued strong top line growth
and higher margins. We are making good progress toward delivering on our
financial targets this year and in 2026," says Geir Holmgren, CEO of Gjensidige.

-We are very pleased that we have seen a solid increase in the number of
customers this year, reaching 850,000 customers in Private Norway. This shows
that we continue to deliver high value to our customers," says Holmgren.

Gjensidige Forsikring Group recorded a profit before tax expense of NOK 2,067.4
million (2,337.6) for the quarter. The profit includes a negative impact of NOK

in the pension business. The profit after tax expense from continuing operations
was NOK 1,563.8 million (1,788.2).

General insurance

Insurance revenue increased by 13.3 per cent to NOK 11,201.9 million (9,888.8)
in the quarter, or by 13.0 per cent measured in local currency. Adjusted for a
non-recurring effect related to the change in recognition of home seller
insurance policies in Private Norway, the growth was 11.3 per cent in local
currency. This was mainly driven by pricing measures across the private and
commercial portfolios in all geographies, solid renewals in the commercial
portfolios and higher volumes in Denmark and Sweden.

The insurance service result was NOK 2,270.6 million (1,590.0). The increase was
driven by a higher insurance revenue and an improved loss ratio.

The combined ratio was 79.7 (83.9). The loss ratio decreased by 3.2 percentage
points, mainly driven by an improvement in the underlying frequency loss ratio
and lower large losses. Lower run-off gains contributed negatively. The
underlying frequency loss ratio improved by 1.4 percentage points. All segments
showed an improvement, except Commercial in Denmark.

The cost ratio improved by 1.0 percentage points, reflecting revenue growth and
operational efficiency.

Pension

The pension segment recorded a profit before tax expense of minus NOK 414.5
million (123.8), with the decrease mainly reflecting the non-recurring expense
related to the core IT system. A lower net finance income also contributed to
the decrease in profit.

Financial result

The financial result for the quarter was NOK 534.0 million (1,306.5),
corresponding to a return on total assets of 0.8 per cent (2.1). The result for
the quarter reflects positive return from all asset classes, driven by running
yields, lower credit spreads and positive equity and real estate markets.

Other items

Other items amounted to minus NOK 229.6 million (minus 117.1). The decrease was
mainly driven by profits from natural perils insurance transferred to the
natural perils pool and provisions related to the termination of cooperation
agreements with seven fire-mutuals effective from 2026.

Discontinued operations

The profit from discontinued operations was NOK 40.7 million (minus 91.2). The
loss in the third quarter of 2024 included a NOK 123.0 million write-down of
goodwill related to the agreement on the sale of ADB Gjensidige. Adjusted for
this, the profit improved, reflecting a higher insurance service result and
lower net financial income. The insurance service result from discontinued
operations was NOK 33.4 million (12.9), reflecting higher run-off gains and
lower loss and cost ratios.
