Turnover 2025: 35,9 M€

Perspectives 2026: Targeted Turnover to be 
between 38 M€ and 42 M€
driven by the continued development of services and the rebound in sales of export solutions, particularly in aquaculture

BIO-UV Group (Euronext Growth^® - FR001334549 - ALTUV), a specialist in water treatment and disinfection systems using UV, ozone, salt electrolysis, and AOP, publishes its annual turnover for the 2025 financial year (ended 31 December 2025).

Since January 1st, 2025, BIO-UV Group has adopted a new presentation format for its segment information in order to reflect the Group's new commercial organisation. Business is now broken down into three divisions: Products, Solutions, and Services & After-Sales Market.

At the end of the 2025 financial year, BIO-UV Group posted consolidated revenue of €35.9 million, down 9% compared with 2024.

Activity by applications

The Services & After-Sales Market division, which covers sales of engineering, training and spare parts for all of the group's activities, saw its annual turnover increase significantly, by +17% to €13.3 million. This activity benefits from the development of the equipment installed over the last 25 years at BIO-UV and Corelec, and over 35 years at Triogen.

Driven by the sharp increase in these services and the after-sales market, which are sources of more recurring and higher-margin revenue, BIO-UV Group expects its gross margin to improve in the 2025 financial year.

The Products division, which includes sales of disinfection equipment and systems (UV, salt electrolysis, ozone, AOP) for recreational water in France and abroad, returned to growth in the second half of the year (+6%), ending the year with a limited decline of -3%, penalised by a swimming pool market that fell sharply in 2025.

According to the FPP (French Federation of Swimming Pool and Spa Professionals), the first signs of recovery are visible for 2026, with order books improving (a 7.5% increase in quotes issued in the third quarter of 2025 alone).

The Products division continues to gain market share, particularly in France, thanks to salt electrolysis technology and the new AKERON range developed by its subsidiary Corelec.

The Solutions division, which manages global water treatment projects (aquaculture, wastewater, industrial water, ballast water), combining integrated equipment and technology solutions (UV, ozone) with engineering services, saw its turnover decline by 33% in 2025, penalised by various factors: 

• The impact of the end of the retrofit market in the maritime sector since September 2024;

• The structuring of the international sales organisation and particularly long sales cycles in the aquaculture sector have delayed the implementation of projects expected in 2025.

   

In the aquaculture sector, however, BIO-UV Group took a strategic step forward in December 2025, signing a major contract with a global fish production company to supply water treatment and disinfection solutions incorporating the Group's technologies.

This contract, which will be rolled out in 2026, is a key milestone for the BIO-UV Group's expansion into a rapidly growing market, driven by structural challenges in terms of health safety, sustainability, and water resource optimisation. It paves the way for further commercial developments, both in terms of equipment and related services and maintenance.

Perspectives

In 2026, BIO-UV Group aims to return to organic growth and is targeting annual revenue of between €38 million and €42 million, supported by (i) the continued dynamic development of Services & After-Sales, (ii) a return to normal activity levels in the swimming pool market, and (iii) a rebound in the Solutions division driven by aquaculture exports, with the completion of new business deals and the continued steady development of solutions for wastewater and industrial water.

Finally, BIO-UV Group confirms its ambition to continue reducing its financial debt and resume its external growth policy to develop new services or conquer new territories. In view of the commercial upheavals in North America, BIO-UV Group does not rule out other geographical areas for such development.

Financial Agenda 

The publications will be released after the close of trading on Euronext Paris.
