Séché Environnement: Activity as of September 30, 2026

Q3 contributed revenue up +11%, o/w +5% on an organic basis¹

2026 revenue target confirmed

LAVAL, France--(BUSINESS WIRE)--Regulatory News:

Séché Environnement (Paris:SCHP):

Q3 2026 confirms the return to growth in France and the continued strong momentum of expansion internationally.

In France, growth is driven by the strong contribution from the Services segment, improved performance in the Circular Economy segment, and the resilience of the Hazard Management segment.

Internationally, most geographic regions are showing a significant increase in business activity, in line with previous periods. The solid contributions from subsidiaries acquired at the start of the year are reinforcing sustained growth in this segment.

These positive developments enable Séché Environnement to confirm its revenue target for 2026.

Q3 2026 showed a strong level of activity, with contributed revenue (€308.8m) up +11.4% on a reported basis and 4.6% on an organic basis¹ , driven by a return to growth in France and strong performance in international markets.

In France, with activity up 1.8%, the industrial and municipal markets confirmed their resilience. The Hazardous Waste business line posted significant growth, supported by the Services and Circular Economy activities, while the Non-Hazardous Waste business line continued to be impacted by lower electricity sales due to the industrial accident early this year at a Waste-to-Energy Plant² .

The International segment confirmed its sustained growth momentum (+27.8% on a reported basis and +9.4% on an organic basis) across all regions, and particularly in Latin America and Southern Africa.

Over the first nine months, Séché Environnement generated contributed revenue of €916.6m (vs. €857.4m a year earlier), up +6.9% on a reported basis and +0.2% on an organic basis.

These positive trends are expected to continue over the coming months and reinforce the target of contributed revenue of between €1,230m and €1,260m for the current fiscal year¹.

Comments on Business Performance in Q3 2026

In Q3 2026, Séché Environnement reported consolidated revenue of €330.2m, compared to €295.5m a year earlier.

The reported revenue includes non-contributed revenue³ of €21.4m compared to €18.2m a year earlier, which breaks down as follows:

In €m	Q3 2025	Q3 2026
“IFRIC 12” investments	-	2.4
General Tax on Polluting Activities (TGAP)	18.2	19.0
Non-contributed revenue	18.2	21.4

The scope effect amounted to €17.2m: it comprises contributions from Hidronor (Chile) totaling €12.6m and from La Filippa (Italy) totaling €4.6m.

The currency effect was positive at +€1.4m compared to (€0.7m) a year earlier and primarily reflects the appreciation of the South African rand (ZAR) and, to a lesser extent, South American currencies against the Euro.

Excluding non-contributed revenue, contributed revenue totaled €308.8m in Q3 2026, compared with €277.3m a year earlier, marking an increase of +11.4% on a reported basis and +4.6% on an organic basis compared with the same period in 2025.

This trend reflects continued strong activity internationally and a return to growth in the French market.

Contributed revenue	277.3	308.8	+11.4%	+4.6%

In Q3 2025, revenue at constant exchange rates would have totaled €278.7m, reflecting a positive currency effect of €1.4m for the period.

The France perimeter confirmed the strength of its Industrial and Municipal markets, particularly in the Hazardous Waste sector, while the International perimeter posted sustained growth in most geographic regions:

• In France, revenue stood at €178.8m, marking a +1.8% increase compared to Q3 2025.
  Growth is notably driven by the Hazardous Waste business line. It is supported by the significant contribution of Services activities, particularly those in the Environmental Emergency sector, while Circular Economy activities were generally better oriented and Hazard Management activities confirm their resilience.
• The International perimeter reported revenue of €130.0m, up +27.8% compared to Q3 2025 (on a reported basis) and +9.4% on an organic basis, reflecting continued strong organic growth momentum in most geographic regions:
  • In Europe, the increase in revenue (+5.2% to €49.2m) reflects the positive performance of platform operations in Italy and the strong growth of Solarca (industrial maintenance—Spain);
  • In Southern Africa, the sharp rise in business (+13.8% at constant exchange rates to €28.3m) reflects the strong contribution from Spill Tech (environmental emergency response) and the positive performance of Interwaste (South Africa) and Rent-A-Drum (Namibia);
  • In Latin America, with revenue up +21.7% at constant exchange rates to €16.8m, the geography benefited from strong activity among industrial customers and the sustained contribution of multi-year service contracts;
  • In Asia, Eco posted growth of +4.8% at constant exchange rates, with revenue of €18.4m, reflecting the strength of Singapore’s industrial markets and the gradual rollout of materials recovery activities (chemical purification), while the Services activities (mainly soil remediation contracts) recorded a slight decline in invoicing after a particularly strong H1 2026.

Analysis by Activities

Consolidated figures

In €m	Q3 2025	Q3 2026	Gross Change	Organic Change
Services	137.6	153.6	+13.1%	+10.5%
of which scope effect	-	2.1
Circular Economy	72.5	74.8	+3.3%	+2.5%
of which scope effect	-	0.4
Hazard Management	69.0	80.3	+16.3%	-4.7%
of which scope effect	-	14.7
Contributed revenue	277.3	308.8	+11.4%	+4.6%

Growth in Q3 2026 was driven by the Services activities in France, Southern Africa, and Latin America. The Circular Economy activities, particularly materials recovery in France, returned to growth, while the Hazard Management activities posted non-significant weaker performance:

• The Services activities generated revenue of €153.6m, a sharp increase compared with the same period last year (+13.1% on a reported basis and +10.5% on an organic basis). This change reflects:
  • In France: the strong contribution from the Environmental Emergency business, alongside solid activity level from the Comprehensive Offers and Industrial Water Treatment businesses;
  • Internationally: the strong performance of Solarca in Spain (chemical cleaning), which benefits from a robust order backlog, and the contribution of major services contracts (Total Waste Management) in Latin America.
• The Circular economy activities generated total revenue of €74.8m, up +3.3% on a reported basis and +2.5% on an organic basis. This trend demonstrates:
  • In France: the return to growth for materials recovery activities (particularly solvent regeneration and chemical purification) within the Hazardous Waste business line, while electricity sales within the Non-Hazardous Waste business line remain hampered by the accident that occurred early this year involving the turbogenerator at a major waste-to-energy plant⁴ operating under a public service delegation contract.
  • Internationally: Eco posted significant activity level with the launch of its new solvent regeneration and chemical purification operations, and Valls Quimica (solvent regeneration) returned to growth after a weaker H1 2026.
• Hazard Management activities generated revenue of €80.3m, up +16.3% on a reported basis. The 4.7% organic decline, which is not representative of the resilience of these markets, primarily reflects:
  • In France: the apparent decline in hazardous waste incineration due to the transfer, at the beginning of the fiscal year, of a customer portfolio from Trédi (France) to Mecomer (Italy), while both business lines confirmed the strength of the markets with industrial clients and local governments;
  • Internationally: the positive performance of these activities in Latin America and Southern Africa, and Eco’s more selective approach to markets, focusing on the added value of business.

Analysis by Business Lines

Consolidated Data

In €m	Q3 2025	Q3 2026	Gross Change	Organic Change
Hazardous waste	197.1	224.3	+13.8%	+7.9%
of which scope effect	-	10.7
Non-hazardous waste	80.2	84.5	+5.4%	-3.4%
of which scope effect	-	6.5
Contributed revenue	277.3	308.8	+11.4%	+4.6%

In Q3 2026, the significant organic growth in the Hazardous Waste (HW) business line underscores the strength of industrial markets in France and internationally, while the Non-Hazardous Waste (NHW) business line was impacted in France by a decline in electricity sales due to the failure of the turboalternator in a waste-to-energy plant operating under a public service delegation contract.

• The Hazardous Waste business line reported revenue of €224.3m, up +13.8% on a reported basis and +7.9% on an organic basis. This significant increase reflects the positive trend in markets, particularly industrial markets - both in France and internationally:
  • In France, the business line is supported by strong performance in the Services business and a return to growth in the Circular Economy business, particularly in materials recovery (solvent regeneration, chemical purification, etc.);
  • Internationally, the solid growth is supported across all activities in most regions.
• The Non-Hazardous Waste business line reported revenue of €84.5m, up +5.4% on a reported basis but down -3.4% on an organic basis.
  This trend is primarily attributable to:
  • In France, a decline in electricity sales due to the failure, early in this year, of a turbogenerator at a power plant operating under a public service delegation contract, and a lower contribution from some Services activities (“spot” contracts for soil remediation) compared to the same period last year;
  • Internationally, strong growth in NHW activities in Southern Africa.

Growth Targets Confirmed for 2026

The Q3 2026 confirms a return to growth for operations in France and sustainable growth momentum internationally.

In an uncertain macroeconomic environment, Séché Environnement anticipates that these positive trends will continue in the coming months. In France, the Q4 will be compared to the low base of the same period in 2025, and operations are expected to confirm their resilience. Internationally, the main geographic regions are expected to continue their sustained growth.

These favorable prospects enable Séché Environnement to confirm its target of contributed revenue of between €1,230m and €1,260m for the current fiscal year, including a dynamic contribution from the scopes acquired at the beginning of the year and organic growth ranging between +2% to +3%.

APPENDIX 1

Definitions Related to Contributed Revenue

IFRIC 12 Revenue: investments made in concession assets, re-billed to the Grantor, and recognized as revenue in accordance with IFRIC 12.

TGAP: General Tax on Polluting Activities paid by the waste producer and collected on behalf of the government by treatment operators. This tax is remitted to the government without impacting operating margins.

Its year-to-year change according to fiscal regulations and to the sector and type of treatment results in the recognition in reported revenue of:

• Non-economic revenue resulting from the increase in the amount of tax collected, particularly within the Non-Hazardous Waste business line;
• Differentiated trends across business lines and activities that are not representative of their economic performance, particularly within the Hazard Management activities (thermal treatment and final waste management).

Its restatement as non-contributed revenue has no impact on operating margins, particularly EBITDA.
