generation volumes and power prices.
  · Operating profit was EUR 634 (935) million.

Summary of outlook

  · The Generation segment's estimated Nordic generation hedges: approximately
90% at EUR 42 per MWh for the remainder of 2025, approximately 70% at EUR 41 per
MWh for 2026 and approximately 45% at EUR 39 per MWh for 2027.
  · UPDATED: For 2025, the annual optimisation premium included in the achieved
power price for the whole outright portfolio is estimated to be approximately 10
EUR/MWh (previously 7-9 EUR/MWh).
  · UPDATED: In 2025, the total generation volumes are expected to be clearly
below the normal level. Currently, the expected decrease of total nuclear
volumes for the full year is 3.6 TWh, 3.0 TWh of which realised in the first
three quarters of 2025. Fortum assumes that its annual hydro volume in 2025 will
be below that of a normal hydro year, which has been 20-20.5 TWh.
  · Capital expenditure for 2025-2027, including maintenance but excluding
acquisitions, is expected to be approximately EUR 1.4 billion, of which annual
growth capital expenditure is expected to be EUR 150-300 million and annual
maintenance capital expenditure EUR 250 million.
  · Capital expenditure for 2025-2027, including maintenance but excluding
acquisitions, is expected to be approximately EUR 1.4 billion, of which annual
growth capital expenditure is expected to be EUR 150-300 million and annual
maintenance capital expenditure EUR 250 million.

Fortum's President and CEO Markus Rauramo:

“The third quarter is typically a quarter with seasonally lower power prices and
volumes. This year, spot prices in the third quarter were notably higher than
last year due to lower hydro reservoir levels, nuclear availability and wind
speeds. Nordic energy demand in the quarter was at the same level as last year,
with a rise in non-industrial consumption. After showing signs of recovery
earlier this year, industrial demand experienced a slowdown, particularly in
Sweden.

Our third-quarter comparable result was affected by the decline in the
Generation segment's result mainly due to lower generation volumes but also due
to lower hedge prices. Our nuclear and hydro output was as much as 1.7 TWh below
last year's third quarter, mainly due to the continued unplanned outage
throughout the quarter at the Oskarshamn nuclear plant and lower hydro inflows.

Despite this, our achieved power price of 46.1 EUR/MWh was two euros higher than
last year, supported by higher spot prices and strong physical optimisation. We
also updated our optimisation premium for full-year 2025 to be approximately 10
EUR/MWh from earlier guidance of 7-9 EUR/MWh. The Consumer Solutions segment
recorded another strong quarter with its strongest third-quarter comparable
operating profit so far, driven by improved electricity and gas sales margins.
The Other Operations segment also saw an improvement in its comparable result.

Our financial position remains strong with financial net debt of EUR 1.3 billion
and a leverage ratio of 1.0 times at the end of the third quarter.

During the third quarter, we announced the acquisition of a project development
portfolio for wind power in Finland from the German renewables developer and
constructor ABO Energy. With the acquired 4.4 GW portfolio, Fortum's pipeline of
onshore wind and solar projects in the permitting phase across the Nordic
countries reaches approximately 8 GW, with more projects in the early
development phase. The transaction is expected to be completed in the fourth
quarter.

After the reporting period, we announced that our coal exit is progressing with
the decarbonisation of the Zabrze combined heat and power (CHP) plant in Poland.
We will invest approximately EUR 85 million in the Zabrze plant's retrofit and
are committed to exiting coal in all our operations by the end of 2027. A year
ago, we announced the decarbonisation of the Czestochowa CHP plant in Poland.

We continue to see robust underlying customer demand from various industrial
sectors, which we believe reflects the long-term power demand growth despite the
recent slight decrease in Nordic industrial demand. The operating environment in
the Nordics is influenced by current political and regulatory uncertainties,
which can impact the timing of large-scale industrial investment decisions.“
