Title

Tallinna Vesi’s fourth-quarter sales reached €18.9 million

Message

The sales of AS Tallinna Vesi in the fourth quarter of 2025 were EUR18.9 million,
up by 5.9% compared to the same period last year. Growth in revenue was mainly
affected by price changes related to investments.

In the fourth quarter, investments amounted to EUR18.6 million, which is 15.6%
more than in the same period of 2024. Aleksandr Timofejev, the CEO of Tallinna
Vesi, said that in the fourth quarter the company moved ahead with planned
investments and was reassured that its earlier environmental investments had put
it on the right track. "The Green Company of the Year award we received at the
end of the year shows that we are making an impact and that we are on the right
track in investing for the future. When planning investments, we must consider
not only future trends and operational continuity, but also the affordability of
water services for consumers. At Tallinna Vesi, we are responsible for providing
drinking water to about half a million people, as well as ensuring that
wastewater is treated in an environmentally friendly way and returned to
nature," said Timofejev. In 2025, Tallinna Vesi invested a total of EUR56 million.

"On the last day of 2025, an exceptional natural event put our crisis plan to
the test, but the team quickly resolved the disruptions that occurred. Once
again, we apologise that many people in Tallinn had to spend New Year's Eve
stocking up on water, which was otherwise readily available from their taps for
all the other 364 days of the year. The water supply was restored to all
consumption points during New Year's Eve. We are analysing technologies to
mitigate the impact of similar natural events and improve customer service based
on this experience," said Aleksandr Timofejev.

The quality of drinking water remained excellent throughout the fourth quarter,
meeting 99.9% of all quality requirements. During the quarter, the company took
1,019 water samples. According to Timofejev, clean tap water is ensured by an
efficient water treatment process, regular monitoring of the water distribution
network and ongoing preventive maintenance activities, as well as timely
investment. Revenue from the sale of water services increased by 7.3% year-on-
year, or EUR1.11 million, to EUR16.33 million. Revenues from the sale of water
services decreased for water services to business customers and increased for
water services to private customers. The change in the sales of water services
was mainly due to the new prices for water services introduced on 1 May. These
prices took into account both the legal obligation to harmonise prices for
private and business customers by 1 July 2026, and the need for investment to
ensure the sustainability of water services.

Tallinna Vesi's annual return on assets was 4.2%. The company's net profit for
the fourth quarter of 2025 was EUR4.51 million, which is an increase of EUR0.36
million compared to the same period the previous year. The growth in net profit
has been driven by operational efficiency and the justified return on
investments made to ensure a clean environment and service continuity.

"The services provided by our subsidiary Watercom and the successful start-up of
the cogeneration plant, which produced 100% of the heat and 59% of the
electricity needed for wastewater treatment, made a significant contribution to
the company's financial results," explained Aleksander Timofejev. The effective
management of treatment processes also had a positive effect on this result.

Tallinna Vesi aims to provide an excellent customer experience, future-proof its
infrastructure and ensure the continuity of the vital service it provides, all
the while keeping the price for the service affordable for consumers.

At the water treatment plant, activities related to the reconstruction of the
osonation stage and the procurement of the new building design are ongoing.

In wastewater treatment, the installation of primary and secondary screens in
the mechanical treatment, upgrading of the biological treatment, reconstruction
of the sludge treatment, and renovation of the secondary clarifiers have been
completed. Investments in the wastewater treatment plant amounted to EUR15.3
million in 2025.

By the end of the fourth quarter, we had rehabilitated and constructed 45.1
kilometres of pipes. Almost half of these, or 22 kilometres, were built using
environmentally friendly no-dig methods. We are working closely with the City of
Tallinn and other partners so that we can complete as much work as possible at
the same time.

In the fourth quarter, major pipe construction work was carried out on Kolde
Avenue as part of the development of a strategic stormwater receiving system for
the North Tallinn area, on Peterburi Road in cooperation with the City of
Tallinn, and on Retke Road in cooperation with Utilitas. Pipe construction also
continued on Paljassaare Road. Construction of the Nõlvaku collector is in its
final stages, with the final works to upgrade ventilation systems underway. Work
started on the reconstruction of water and sewer pipes in Lauteri Street and at
the intersection of Endla and Tehnika streets. The renovation of the water pipes
on Bornhöhe Road, as well as the construction work in Tuukri and Uus-Sadama
streets as part of the extension to the stormwater collector starting from Reidi
Road, has been completed. In cooperation with the City of Tallinn and Utilitas,
the renovation of Värvi and Mustjõe streets was completed.

A stormwater scheme is being developed for the Mustamäe area. The scheme uses
nature-based solutions to ensure longer retention times for stormwater and
create a greener urban environment. These stormwater solutions help to reduce
the risk of flooding during periods of heavy rainfall.

In the fourth quarter, the quality of treated effluent from the Paljassaare
wastewater treatment plant outperformed the effluent standards. To keep the
Baltic Sea clean, the company uses efficient treatment processes that helped to
remove approximately 326 tonnes of solid waste, 55 tonnes of grit, 511 tonnes of
nitrogen and 64 tonnes of phosphorus from wastewater during the fourth quarter
of 2025.

The water loss rate in the water distribution network fell to 11.87% in the
fourth quarter from 12.67% a year earlier. In order to keep water loss rates
low, the company carries out continuous online monitoring of the water
distribution network and continues with its planned water network rehabilitation
programme.

By the end of the fourth quarter of 2025, Tallinna Vesi had installed smart
meters for more than 80 per cent of its customers, with the project due to be
completed in 2026. The new meters provide information on water consumption,
allowing leaks in customers' pipes to be detected as early as possible. This
will help to protect the environment and minimise the risk of property damage
caused by water accidents. The switch to smart meters has received very positive
feedback from customers, and the meters provide the water company with a clear
picture of water consumption in the service area.

As a vital service provider, Tallinna Vesi recognises the importance of raising
consumer awareness of the benefits of fresh tap water and of environmental
protection. In the fourth quarter, we took part in the Impact Day sustainability
festival, and opened the doors of the water treatment plant to the public as
part of the Open House Tallinn architecture event.

We were awarded the title of Green Company of the Year at the Estonian
Successful Companies Awards. The Estonian Waterworks Association recognised two
of our employees and named our cogeneration plant the Water Achievement of the
Year.

AS Tallinna Vesi is the largest water utility in Estonia, providing services to
approximately 25,000 private and business customers and approximately 500,000
end consumers in Tallinn and its surrounding municipalities. Tallinna Vesi is
listed on the main list of the Nasdaq Tallinn Stock Exchange. The largest
shareholdings in the company are held by the City of Tallinn (55.06%) and the
energy group Utilitas (20.36%). 24.58% of the company's shares are freely
floating on the Nasdaq Tallinn Stock Exchange.
