Solid 9.4% increase in consolidated revenue in the first quarter of 2026

• Growth of +10.2% at constant exchange rates and scope

• Growth of +7.4% in the Explosives & Drilling & Blasting businesses, +5.5% for Urban Mining and +14.1% for Global Technical Solutions

• Sustained growth in the Europe, Mediterranean and Americas region (+11.3%) and the Africa Asia Pacific region returns to growth in 2026 (+4.2%)

EPC Groupe (Euronext - EXPL) recorded a sustained increase in consolidated revenue of +9.4% (+10.2% at constant exchange rates and scope) in the 1^st quarter of 2026, reaching €152.9 million.

The start of the financial year thus marks an acceleration in growth (+6.0% for the full 2025 financial year), driven by sustained activity in Explosives & Drilling & Blasting business (+7.4%) and the return to growth in the Africa Asia Pacific region (+4.2% and +8.6% at constant exchange rates and scope) following a decline in 2025, primarily due to lower sales in Saudi Arabia. The Global Technical Solutions (GTS) business also continued to grow at a steady pace (+14.1%).

The growth momentum of the markets in which the Groupe operates is confirmed in 2026.

To ensure the market is fully informed, the Group presents its quarterly financial information using two approaches:

• Consolidated results in line with the segment reporting in the annual financial statements (with proportional consolidation of its joint ventures), the method of reporting preferred by management and financial partners;
• IFRS revenue, excluding joint ventures.

1 The change at constant scope and exchange rates is calculated by converting the 2025 figures using the average monthly exchange rates for 2026 and by adding (or subtracting) the additions (or disposals) to the scope of consolidation from the 2025 figures.

Revenue from consolidated operations stood at €152.9 million in the 1^st quarter of 2026, compared with €139.8 million in the 1^st quarter of 2025, representing growth of +9.4% (+10.2% at constant exchange rates and scope).

The consolidation of Pirobras (since¹June 2025) had a positive impact of +1.2 percentage points on annual growth, whilst exchange rate fluctuations (primarily the US dollar, Canadian dollar and pound sterling) had an adverse impact of -1.9 percentage points.

GROWTH IN REVENUE FROM CONSOLIDATED OPERATIONS ACROSS ALL BUSINESS SEGMENTS

The Groupe's growth in the Explosives & Drilling & Blasting business stood at +7.4%. The decline in activity in Saudi Arabia and France was largely offset by the excellent performance in the Americas (Canada, first-time consolidation of Brazil) and Africa (Senegal, Morocco, Gabon and Burkina Faso).

The Urban Mining division (comprising Demolition and the Circular Economy) has continued to perform well, recording growth of 5.5% compared with a 1^st quarter that remained weak in 2025 in the wake of the Paris Olympic Games.

The GTS business saw growth of +14.1%, driven by Vibraquipo's software and measurement instruments.

THE EUROPE, MEDITERRANEAN AND AMERICA REGION REMAINS ON TRACK IN THE FIRST QUARTER OF 2026

Europe, Mediterranean and Americas

The Explosives & Drilling & Blasting business is performing very well in the Europe, Mediterranean and Americas region (+8.9%) despite unfavourable weather conditions in Europe. It thus confirms the sustained growth rate seen in the 4th quarter of 2025 (+9.9%).

In France, domestic business remains very sluggish in a construction and civil engineering market that has been hampered by particularly adverse weather conditions this winter. The temporary suspension of one of the TELT (Lyon-Turin Euralpin Tunnel) contract packages has also weighed on construction activity. Direct export activity also declined due to the postponement of a major shipment to the 2^nd quarter. Overall, revenue fell by 10.9% in the 1^st quarter of 2026 in France.

The start of the year saw a slight decline in Italy (-2.4%), which also faced a turbulent winter that slowed down quarrying activity. Spain fared better (+26.5%), notably thanks to an excellent performance in the distribution sector in the Valencia region.

Despite a weak March in Morocco (Ramadan fasting), business in the kingdom was extremely buoyant this quarter, with growth at constant exchange rates of +20.3% in the aggregates business and +40.3% in the construction business. The subsidiaries are reaping the benefits of strong activity on major projects (notably the port of Dakhla), new contracts won in the quarrying sector at the end of 2025, and export business, which is now a recurring source of revenue.

Business at the Swedish subsidiary remained sluggish this quarter, with the expected growth failing to materialize due to the extreme weather conditions encountered. The UK had a strong 1^st quarter, with growth of +18.9% at constant exchange rates, as the market share gains made in 2025 began to bear fruit. Ireland was also very buoyant, with growth of +18.0% in a market that remains buoyant.

As is usually the case in winter, mining activity drove growth in Canada. The two main mining sites performed well despite conditions in the Far North being difficult once again this year. Construction of the IAMGOLD plant is continuing in parallel with the supply of explosives to the mine currently being provided by the Dane plant in Ontario.

Operations in Brazil were hampered by technical difficulties at the country's leading nitrate producer, which forced the company to slow down production. The situation returned to normal in early March. The management structure is being strengthened to enable the company to capitalize on significant opportunities in the Brazilian market and for exports.

Africa Asia-Pacific

The Africa-Asia-Pacific region returned to clear growth this quarter despite a still unfavorable year-on-year comparison in Saudi Arabia.

In the Middle East, MCS (in Saudi Arabia) is down on the 1^st quarter of 2025 (-9.6% at constant exchange rates). The Mansoura Massara plant, which came on stream at the end of 2025, is gradually ramping up production. Output is expected to accelerate in the coming months following the new mining contracts secured in March (see below). The war in the Arabian Gulf has had no significant impact on business.

Despite the disruptions caused by the ongoing conflict in March, business grew slightly over the quarter in the United Arab Emirates. The commissioning of the new production unit gives this joint venture a significant competitive advantage over its rivals.

Activity is growing strongly in New Caledonia Activity gradually picked up in the 1^st quarter of 2025, providing a favourable year-on-year comparison. The difficulties currently faced by nickel producers in Indonesia (who are heavily reliant on raw materials from the Gulf) could have a positive impact on the business of EPC Group's client in the coming months.

Growth continues at a steady pace in Malaysia, with revenue up by +15.3% at constant exchange rates

In sub-Saharan Africa, business performance varies by country.

Pending the start of the Montage Gold contract in the 2^nd half of 2026, Ivory Coast has seen a slight decline in activity (-3.7%) due to lower volumes on existing contracts. This is also the case in Guinea, with a 29.3% decline at subsidiaries working for the CBG, where production remained low at the start of the year. The start-up of the detonator assembly line in March and the first sales on the market have boosted growth at the subsidiary leading this project, with an increase of over 50% compared to the 1^st quarter of 2025.

Cameroon and Benin are lagging this quarter. The political climate continues to hamper business activity.

Business in Senegal is extremely buoyant (+74.5%), driven by a surge in mining activity. The same is true in Gabon, which has continued to perform well, with business volumes doubling despite ongoing significant logistical constraints. Burkina Faso is also seeing significant growth.

HIGHLIGHTS OF THE FIRST QUARTER OF 2026

Signing of three major contracts in the gold mining sector in the Middle East

Through its subsidiaries, EPC Groupe announces a significant strengthening of its position in the Middle Eastern mining market following the signing of three major contracts in the gold mining sector.

Valued at approximately €240 million, these contracts were concluded by the MCS joint venture (40.0% owned by EPC Groupe) for terms of 5 and 7 years. They cover the following services: the supply of explosives and accessories from local production, logistics and on-site delivery, and the execution of operations.

Strengthening of positions in Canada with the signing of two major contracts in the metal mining sector

EPC Groupe has significantly strengthened the position of its subsidiary EPC Canada in the Canadian mining market, through the award of a contract in Ontario with IAMGOLD and the extension of its strategic partnership with MFQ (Minerai de Fer Québec).

EPC Canada has been awarded a long-term contract to supply explosives and mining services at the Coté Gold mine in Ontario, owned by the IAMGOLD group. Valued at over 100 million Canadian dollars (approximately 67 million euros), this four-year contract covers a full range of mining services, including the supply of explosives and accessories from a dedicated plant, logistics and on-site delivery, as well as the execution of mining operations.

Building on this momentum, EPC Canada and MFQ have also agreed to extend their strategic partnership for on-site emulsion production for a further four years. This contract extension is accompanied by the modernization of logistics and production lines to make them more efficient and flexible.

UPDATE ON THE PROPOSED MERGER BETWEEN EPC GROUPE AND SOCIÉTÉ SUISSE DES EXPLOSIFS

Cross-due diligence work between the two groups has continued intensively since the announcement to the market of exclusive negotiations between EPC Groupe and SSE. This has confirmed the strategic alignment of the merger and the cultural affinity between the two companies.

The transaction remains subject to the negotiation of contractual documentation, applicable regulatory conditions precedent, and the approval of the general meetings of EPC Groupe and SSE. The parties hope to complete the transaction by the end of the 3^rd quarter of 2026.

OUTLOOK

Since the outbreak of the war in the Arabian Gulf, the Groupe, like many industrial groups, has faced disruption to some of its supply chains.

The work carried out over the past several years to diversify the supply sources for critical supplies is paying off. No critical supply shortages are anticipated in the short or medium term.

However, rising material costs are a reality that is gradually becoming apparent and having a very significant impact. The Groupe's teams are working to activate contractual mechanisms designed to protect the Groupe's profit margin. EPC Groupe prioritized transparency with its customers during the Ukraine crisis without seeking to take advantage of what were at times tense situations. This partnership-based approach is currently being maintained in order to preserve trust among industry stakeholders during this critical period.

Despite this context, the growth posted by the Groupe in the 1^st quarter confirms the underlying momentum supporting its activities. The rising cost of fossil fuels is accelerating the ongoing electrification drive, and thus the demand for metals. Infrastructure construction and the use of recycled materials are also on the rise.

EPC Groupe's accession to the United Nations Global Compact fits perfectly with this trajectory. The Groupe wishes to contribute, in its own way, to the achievement of these objectives whilst respecting the environment and people.
