ARNHEM, THE NETHERLANDS – March 3, 2008 – ARCADIS (EURONEXT: ARCAD), the international consultancy, design, engineering and management services company again achieved excellent results in 2007. Net income from operations (before amortization and non-operational items) was 25% higher at € 62.3 million. Per share, this is € 3.06 against € 2.47 in 2006. Gross revenue rose 22% to € 1.5 billion, driven in part by a record organic growth of 16%. The margin improved further to 10.5% (2006: 9.4%), and for the first time surpassed the 10% goal. Performance was strong across the board. In all three business lines organic growth was (well) above our targets while margins improved. Geographically, all regions contributed to the improved profits, particularly the Netherlands, Brazil and the United States.

ARCADIS proposes to increase the dividend of € 1.23 per share (2006: € 1.00) to be distributed in cash. This is 40% of net income from operations.

In 2007 we acquired 8 companies, in total adding 1460 people and € 192 million in new revenues. The main acquisition was that of U.S.-based RTKL, a global player in architectural design and planning with 1050 people. In the Netherlands, the acquisition of Alkyon serves to strengthen our position in the strong international growth market for water management. Smaller takeovers in the Netherlands, Germany, Belgium and Chile added specialties while in the U.K. the activities in the environmental market and in project management were expanded.

CEO Harrie Noy about the results: “The excellent performance is a result of strong growth, further margin improvement and a fine contribution from acquisitions. The especially high organic growth underlines the success with which our people were able to capitalize on the favorable current market conditions. The strong focus on clients and on internal cooperation to maximize utilization of knowledge enabled us to increase market share, particularly in environmental markets. The fourth consecutive year of margin improvement is a good indication that our strategic accent on activities with higher added value is reaping results.”

Key figures

(1)          In 2007 based on 20.3 million shares outstanding (in 2006: 20.2 million)

(2)          Excluding amortization and non-operational items

Fourth Quarter

Gross revenue increased 24%. The contribution from acquisitions was 13%; the currency effect 4% negative. Organic growth was high at 15% and remained at a good level in almost all countries. In Brazil, a turn key energy project with a significant amount of subcontracting caused a strong revenue increase. In the United States, organic growth came out to 9%. Here, the strong decline in land development continued, while several large environmental projects that included considerable subcontracting were completed.

Net revenue – the part of revenues produced by our own staff – increased by 21%, of which 16% was a result of acquisitions. The currency effect was 4% negative. The 9% organic growth was lower than gross revenues due to an increase in the level of subcontracting, particularly in infrastructure.

In the fourth quarter, two acquisitions were completed: environmental consultancy Vectra (gross revenue € 14.5 million, 110 employees) in the U.K. specialized in providing health & safety and risk-management services and Idesol (gross revenue € 4 million, 70 employees) in Chile, to strengthen our position in the fast growing mining sector.

EBITA was impacted by two non-operational issues: the sale of real estate in France (book gain € 1.4 million) and the introduction of a share participation plan for employees in the U.K. (charge € 0.1 million). Excluding these two items recurring EBITA grew by 32%. Of this amount 26% came from acquisitions; the currency effect was 4% negative. The organic growth of 9% mainly came from the Netherlands and other European countries. As a result of procedural delays, the contribution from carbon credits from the biogas installations in Brazil was zero in the quarter, while this amounted to € 0.6 million in the fourth quarter of 2006. Corrected for this item, EBITA organically rose 12%. This was somewhat lower than earlier quarters due to the impact of land development in the U.S.

Net income from operations was 16% higher. This is lower than the increase in recurring EBITA, particularly because the 2006 fourth quarter saw non-recurring tax advantages.

Full year

Gross revenue increased 22%. The contribution from acquisitions was 10%; the currency effect 4% negative. At 16%, organic growth was well above our goal of 5%. Almost all countries showed double-digit organic growth, with the largest contributions coming from the Netherlands, the United States and Brazil. In Poland, project delays appear to be over which led to strong activity growth.

Net revenue grew by 20% to above one billion euros. The contribution from acquisitions was 12%; the currency effect 3% negative. Organic growth amounted to 11% and was lower than gross revenue growth as a result of considerable amounts of third party work in energy projects in Brazil and several large environmental projects in the United States.

Excluding the above mentioned two non-operational items, recurring EBITA increased 34% to € 105.9 million. Acquisitions contributed 20%; the currency effect was negative 4%. The organic increase of 18% was the result of profit increases in the Netherlands, Brazil and the United States, while Poland, Germany and Chile also saw better returns. The contribution from carbon credits was € 2.6 million (2006: € 0.6 million).

The margin (recurring EBITA as % of net revenue) improved to 10.5% (2006: 9.4%) as a result of portfolio changes and productivity improvements in existing operations. The strongest increase occurred in buildings: to 9.9% (2006: 7.3%). In the other segments margins also improved, in infrastructure to 8.8% (2006: 8.4%) and in environment to 13.5% (2006: 12.0%).

Financing charges primarily increased as a result of investments in acquisitions. Excluding derivatives to hedge interest and currency risks, financing charges increased to € 8.1 million (2006: € 4.6 million). In addition, the 2006 figure was positively impacted by a one-off interest gain of € 0.5 million.

The tax rate rose to 32.8%, (2006: 30.2%) as a result of the abovementioned non-recurring tax benefits in 2006, geographical changes in taxable income and because option costs in the Netherlands are no longer tax deductible. The loss in associated companies of € 0.8 million (2006: € 0.5 million) resulted from Brazilian energy projects that experienced start-up problems and contract delays. Minority interest increased to € 2.6 million (2006: € 1.5 million), mainly the result of positive developments in Brazil, where ARCADIS owns 50.01% of the shares.

Cash flow, investments and balance sheet

Cash flow from operational activities was at the healthy level of € 79 million (2006: € 86 million). The slight decline compared to 2006 mainly resulted from changes in tax payments and a limited increase in working capital. Investments in acquisitions amounted to € 102 million of which € 17 million was for after payments. Goodwill acquired amounted to € 85 million and identifiable intangible assets amounted to € 15 million.

The balance sheet total rose to € 922 million (2006: € 736 million). Despite the strong organic growth, working capital declined as a percentage of gross revenue. Predominantly due to investments in acquisitions, net debt increased to € 134 million (2006: € 45 million). The balance sheet ratios remained strong. The net debt to EBITDA ratio was 1.0 (2006: 0.4); and the interest coverage ratio was 14 (2006: 17).

Developments per service area

The figures stated below relate to gross revenue developments and discuss the comparison between the full years 2007 and 2006, unless otherwise note.

·      Infrastructure

Gross revenue rose 11% with a currency impact of minus 2% and an acquisition effect of on balance minus 1% as a result of the divestment of Euroconsult. Organic growth was 13%. Principally in the Netherlands solid growth occurred due to investments in (rail) infrastructure and a favorable municipal market. In Belgium, France and Poland, revenues also increased, as they did in Brazil and Chile where investments in mining and energy projects drove growth. In the U.S., water and transportation drove growth, which was somewhat offset by a strong decline in land development due to the poor housing market.

·      Environment

Gross revenue increased 16%. The contribution from acquisitions was 2%; the currency effect negative 8%. The very strong organic growth of 22% mainly came from the United States where the introduction of a client focused business model resulted in a larger market share, particularly with industrial clients. Although no new GRiP® contracts were won, backlog in the United States increased by 16% measured in net revenue terms. In Brazil, activities saw strong growth, particularly for multinationals, while also in most European countries and Chile a healthy growth level was achieved.

·      Buildings

Gross revenue grew 71% of which 60% was a result of acquisitions. This was primarily driven by RTKL (acquired early July) but also included PinnacleOne in the United States and a number of smaller acquisitions in European countries. There was no currency effect. The organic growth of 11% was driven by the expansion in management and consulting services in the Netherlands, Belgium, Germany and the U.K. ARCADIS Worldwide Project Consulting, aimed at services for international property investors, took off strongly. Demand for ‘green buildings’ is increasing strongly, offering opportunities for the combination of real estate and environmental expertise.

Strategy sharpened with higher growth goal

The ARCADIS strategy in recent years has been successful. In the 2003 – 2007 time frame, average annual revenue growth was more than 15%, while margins improved from 6% to 10.5%. Acquisitions and divestments served to adjust the portfolio and change the profile of the Company. Because the strategy is reviewed every 2 to 3 years, this was again done in 2007. This resulted in a revised strategy entitled: ‘Building global leadership’.

The revised strategy builds on our achievements with the sharper ambition to reach leading positions in each of the three market segments in which ARCADIS is active. In infrastructure we want a leading position in rail, water and large transportation corridors. In environment, the goal is a leading market position in environmental services for private companies, while in buildings it is our ambition to create a differentiating position through internationally providing high level design, management and consultancy services. Client focus through systematic account management, globally seamless service delivery and operating as one company from strong local positions, remain core elements of the strategy.

Because of the changing activity mix and the long term market outlook, the growth goal has been raised to15%, with at least half coming from organic growth. The target for the growth of earnings per share was raised to 15% (based on net income from operations and the current financing structure). Both of these goals are excluding currency effects. Because the size of acquisitions can vary considerably, these targets are set as average over a period of a number of years. The margin target was maintained at minimally 10%. The growth goals per business line are as follows:

In case of structural portfolio changes, for example acquisitions, the goals will be re-evaluated. The policy remains aimed at productivity improvement and activities with higher added value and growth potential. Achieving the above mentioned targets will also depend on market conditions.

Outlook

In all countries where ARCADIS is active, expansion and improvement of infrastructure is an important priority. In Europe, the solid economic conditions positively impact the investments in infrastructure, while PPP initiatives are used to solve bottlenecks quicker with private sector money. In the United States, the transportation market is expected to be stable, while the framework contract that was won in New Orleans last year, is a good basis for further growth in the water market. Meanwhile, less than 1% of total revenues comes from the American market for land development, rendering its impact limited. Raw material demand drives continued favorable market conditions in Brazil and Chile.

The considerable attention for sustainability and climate change is positive for the environmental market. Many multinational companies want international service providers, as a result of which our market share in the environmental market can increase further. It is expected that new opportunities will arise in 2008 for GRiP®, both with the U.S. Department of Defense, and with the redevelopment of private sector polluted sites. The acquisition of LFR ($ 127 million gross revenue, 480 employees) completed at the end of January 2008, has strengthened our geographic position in the western United States and adds air quality, industrial hygiene, geotechnical and guaranteed remediation services and will allow us to create synergy benefits similar to BBL.

In the buildings market, our position has been considerably strengthened in recent years with services high in the value chain. RTKL has a backlog that is 40% higher than a year ago, and concentrates on opportunities in hospitals, government buildings and the international market. For project management and consultancy services the backlog is good. Activities in the Middle East will be expanded. With the recently won 5-year facility management contract for Philips, we can further expand these services.

CEO Harrie Noy concludes: “The outlook for ARCADIS is positive. The markets in which we operate offer significant prospects. Our strong home market positions, client focused approach and internal synergy, provide a fine basis for growth and enlargement of our market share. In addition, acquisitions remain high on our priority list. Barring unforeseen circumstances, we expect further growth of revenue and income for 2008.”
