Ghent, 18 July 2025 – 19.30 hrs Press release / Regulated information

Highlights first half-year 2025

• With sales of 53.6 million euros in the first half, the group achieved 17.7% growth. The 2^nd semester 2024 acquisitions were integrated for the first time, with an impact of 9.6%. We also achieved 8.1% organic growth.

• Belgium and France generated a growth of 17.6% and 12.8% respectively (both +2.8 million euros), the Netherlands achieved a growth of 32.5% (+2.4 million euros).

• The Monitoring & Infrastructure division experienced a robust growth of 71.9%/+2.1 million euros whilst the large Environment and Geotechnics divisions increased by 17.3%/3.6 million and 10.8%/2.3 million euros, respectively.

• EBITDA increased from 5.4 million to 5.9 million euros.

• The balance sheet structure remains sound with a solvency ratio of 28% (28.2% as of 31 December 2024) and a debt ratio of 2x EBITDA.

Outlook

• Thanks to the strong performance of the ABO Group's Geotechnical consulting arm and its Monitoring and Infrastructure companies, the group is maintaining its 2025 revenue target of between €105 million and €110 million. The slowdown in the construction sector and public procurement in Belgium and France is not affecting the ABO Group for the time being.

• During the fourth quarter of 2025, a number of large, recently secured contracts for the ministries of defence and the nuclear waste sector will commence.

• From September 2025 the group will be streamlined even more with a focus on the three countries in which we operate, with the appointment of Alexander De Palmenaer (27) as COO for Belgium and Gijs Vanreusel (35) as COO for the Netherlands with the aim of promoting operational and financial efficiency and knowledge sharing. Both De Palmenaert and Vanresuel have been active within the group for several years. Their appointment shows the organisations’ ambition to put a younger generation at the helm.

Frank De Palmenaer, CEO ABO-Group Environment: “ABO-Group is at a tipping point. The Group’s 30th anniversary marks the start of a new era, in which we are making a permanent transition from small-scale projects to large projects commissioned by 3 new categories of clients: defence, nuclear waste management and mining. This shift has several positive consequences for our organisation.

Most of these assignments are recurring, which helps shield us from the effects of a negative economic climate. For example, we are now virtually immune to the turbulence in the construction sector for the next two to three years.

These large-scale projects also require an adjustment in the way we work, which in turn accelerates the integration of our 25 specialised companies. To support this evolution, we are now appointing a COO for Belgium and one for the Netherlands: Alexander De Palmenaer and Gijs Vanreusel. From now on, they will focus on supporting and developing our Belgian and Dutch entities.

These projects also foster the growth of our employees. Greater challenges broaden their knowledge and deepen their expertise. As a result, we are able to serve our clients even better, with a service offering that is unique within our industry.

Finally, we can also state that this tipping point strengthens ABO-Group’s ability to achieve its societal goals: on the one hand, remediating historical pollution caused by more than two centuries of industrial, technological and nuclear activity. On the other, developing solutions to complex societal challenges such as climate change, the energy transition and geopolitical developments requiring an upgrade of defence infrastructure and new mining capabilities for critical raw materials.

As for our financial targets, our half-year results for 2025 show that we are on track to reach our communicated revenue goal for the year. This comes after having already approached our five-year target of 100 million euros in revenue (originally set for 2025) one year ahead of schedule in 2024.”

HY 2025 highlights

Given the slowdown in growth in the construction market and in public procurement, the group managed to achieve organic growth of 3.7 million euros or 8.1%. Combined with the revenue contribution of 4.4 million euros, or 9.6%, through acquisitions in the second half of 2024, being Eco Reest and Demey Infrabureau, group revenue amounts to 53.7 million euros for the first half of 2025. The acquisition of Délo Boringen will not contribute to the results until the 2^nd semester. Only the opening balance sheet was included in the consolidation.

REVENUE PER ACTIVITY

Growth in the Geotechnical division is almost entirely attributable to France where activities normalized following a year of project delays and unforeseen machine maintenance.

The main share of the Environmental Division’s growth is due to the Dutch Eco Reest acquisition, which accounts for 75% of the growth. Moreover, environmental divisions in the field are under pressure as a result of intense competition from small new players entering the market.

The acquisition of Demey Infrabureau represents 79% of the growth of the Monitoring and Infrastructure Division. It is complemented by solid growth in Monitoring, amongst other things as a result of winning major, long-term contracts such as Oosterweel Antwerp and the start-up of GEO-ICT.

REVENUE PER COUNTRY

Belgian activities increased by 2.8 million to 18.9 million euros. Acquisitions in 2024 represent 59% of the increase. Existing Belgian activities are increasing mainly in Monitoring & Infrastructure (see above) and in Environment. With respect to the latter, growth has been driven by large framework contracts and increasing consulting assignments despite the slowdown in the construction market.

Sales from Dutch operations grew by 2.4 million euros to 9.9 million euros. This growth is mainly found in the Environmental Division where the revenue from the Eco Reest acquisition is a major contributor. Our Dutch companies are facing a particularly competitive market combined with the switch to larger-scale projects that pose operational challenges.

The revenue increase in France is a combination of, among other things, the recovery in geotechnical orders following a weak 2024, growth in Environment - partially offset by a decline in geophysics - a specific part of geotechnical engineering.

Margin and net results evolution

The decrease in our EBITDA margin from 11.8% to 11.1% is primarily the result of:

• A negative EBITDA margin in geophysics, where the decline in business means that sales levels are insufficient to cover fixed costs.

• A decline in the margin of Geotechnics in the Netherlands and in Belgium where 2024 was a highly exceptional year.

• A decline in fieldwork Environmental Departments in Belgium and the Netherlands due to increasing competition in basic drilling.

Depreciations rose from 3.7 million to 4.2 million euros. However, this section was positively impacted in 1H24 by a reversal of the ABO Logistics provision to the tune of 0.5 million euros. Abstracting this reversal, depreciation would remain virtually unchanged compared to 1H24.

Mainly due to increased financing for acquisitions, the financial loss increased from 0.8 million euros as of 1H24 to 0.9 million euros.

The increase in the tax expenses is mainly due to the tax credit on R&D in France recorded in 1H24, whilst no such credits were accounted for in 1H25. Given the uncertainty of the amount as well as the timing of such benefits, they are only recognized once they have been granted.

As a result of the above-mentioned effects, net profit decreased from 0.5 million euros in 1H24 to 0.2 million euros in 1H25.

Key points relating to balance sheet and cash flow

ABO-Group achieved a sound cash flow from operating activities of 5.2 million euros in 1H25, up 3.2 million euros from 1H24. Efforts with respect to working capital contributed to this increase to the tune of 2.5 million euros.

Net financial debt increased from 24.7 million euros at the end of 2024 to 25.6 million as of 1H25. The annualized debt ratio thus increases from 2.03 to 2.14 and remains healthy.

The balance sheet total as of 1H25 is 100.9 million euros, an increase of 2.7 million euros as per the end of 2024. In terms of assets the increase is mainly found in goodwill (acquisition Délo Boringen), trade receivables and other current assets, offset by the decrease in cash and cash equivalents. On the liabilities side, the increase in other short-term debt and long-term financial debt is partially offset by the decrease in short-term financial debt.

The full consolidated income statement and balance sheet, statement of changes in equity and consolidated cash flow statement are included below.

Outlook

We observe that in the second half of 2025, the slowdown in the construction sector is becoming more pronounced, which is affecting the number of orders coming from that sector. However, this is precisely the semester where several large projects that we secured are starting up and for which we are currently organizing ourselves.

Over the past years, ABO-Group has acquired specialized niche players, giving us all the necessary expertise and the capacity to participate in the largest projects. These projects relate to military reinvestments in infrastructure, the disposal of nuclear waste and the development of the mining sector under the ‘Critical Raw Materials Act’, aimed at making Europe more self-sufficient in terms of raw materials.

Ongoing geopolitical turbulence is making ABO-Group increasingly resilient to economic cycles, supporting our expectations for continued growth in 2026 and 2027.
