PRESS RELEASE




Signing of a unilateral purchase offer
with a view to acquiring Groupe Flamme
This transaction would strengthen the Group’s
industrial and commercial positions in its
traditional markets across Europe



Séché Environnement announces the signing of a unilateral purchase offer with
a view to acquiring Groupe Flamme, a major player in hazardous waste
incineration in France and a key player in the industrial waste and sanitation
markets in north-eastern France.
The acquisition of Groupe Flamme would enable the integration of significant
hazardous waste treatment capacities that are available and highly
complementary in geographical, industrial and commercial terms with the
Group’s facilities in France and Europe.
A unique opportunity due to the quality of the assets acquired, this strategic
transaction would be fully in line with the Group’s strategy of strengthening its
position in France and Europe in the hazardous waste markets.
On June 5, 2025, Séché Environnement signed a unilateral purchase offer with the
shareholders of the three companies comprising “Groupe Flamme”, namely A.R.F. and
subsidiaries, Flamme Environnement and subsidiaries, and Flamme Assainissement and
subsidiary, with a view to acquiring all of the shares comprising these companies’ share capital.
With approximately 560 employees, Groupe Flamme is a long-standing family-owned operator
in the management of industrial, hazardous and non-hazardous waste, and also carries out
sanitation activities.
It has a strong foothold in the Hauts-de-France region, where it operates primarily, especially
in the hazardous waste incineration sector.

“Groupe Flamme”, a leading hazardous waste management player in France
Posting revenue of approximately €100 million and EBITDA of around €20 million in 20241,
Groupe Flamme collects, recovers, and treats all types of industrial waste. It also operates in
the environmental services and sanitation sectors.
It carries out these three activities through three independent divisions:
 Hazardous Waste Collection and Treatment Division (A.R.F., accounting for
approximately 49% of consolidated revenue in 2024): A.R.F. is present throughout the
value chain, from collection to incineration, through four industrial facilities in the
Hauts-de-France region (Chauny, Vendeuil, St Rémy-du-Nord and Gondecourt).
 Environment Division (Flamme Environnement, accounting for approximately 27%
of consolidated revenue in 2024): dedicated to the management of environmental
services for all types of everyday waste, household waste, recyclable waste, and green
waste through integrated collection, transport, recovery, and treatment services,
backed by multi-year contracts.
 Sanitation Division (Flamme Sanitation, accounting for approximately 24% of
consolidated revenue in 2024): with nine branches in France and Belgium and a
reputation for high-quality services, the Division offers its industrial clients a range of
services including sanitation, pumping, cleaning, and maintenance of their industrial
facilities.
A strategic transaction for Séché Environnement’s development
With the acquisition of Groupe Flamme, Séché Environnement would make significant
progress in its strategic development in core markets, particularly in incineration in France,
while strengthening its position among the leading hazardous industrial waste treatment
players in France and Europe.
Perfectly complementing Séché Environnement’s geographical network in the hazardous
waste markets in France (primarily in western, eastern, and southeastern France at present),
this acquisition would give the Group new access to industrial customers in northern France
and its border regions, where it could offer relevant local solutions to their hazardous waste
management issues, backed by efficient logistics tools, pre-treatment facilities (platforms), and
treatment facilities (incinerators) with significant authorized and available capacities.
These new capacities would accelerate the development of industrial and geographic
synergies within the Group by enabling the internal processing of growing volumes of
hazardous waste from its sorting and consolidation platforms.
In addition, Groupe Flamme would bring to Séché Environnement its recognized technological
expertise in promising industrial markets where the Group currently has limited presence, such
as aerosol and oil recovery.
A partnership based on shared values and a common vision
Maxime Séché, Chief Executive Officer of Séché Environnement, said: “We would be delighted
to welcome Groupe Flamme’s employees into the Séché Environnement family.
This merger would mark the union of two family-owned companies guided by a common vision
and strong values: a solid regional presence, a tangible commitment to environmental
responsibility, a strong service mindset, and genuine care for the men and women who bring
our businesses to life.

Beyond the obvious industrial and commercial synergies, this project is based on shared
convictions, complementary expertise and a common ambition to support the ecological
transition.
Together, we can enrich our industrial service offering, accelerate our development in the
Hauts-de-France region and nationwide, while consolidating our presence in European and
international markets.”
The acquisition would be carried out on the basis of a price of approximately €300 million for
100% of the shares. It concerns 100% of the share capital of the companies involved and
would be financed with the Group’s available cash.
The Groupe Flamme companies will now initiate the information and consultation process with
their employee representative bodies.
Closing of the acquisition would be subject to approval by the French Competition Authority.
