Operating revenues and profit in the first nine months of 2006
In the first nine months of 2006, Grontmij’s profit increased by 62% compared to the same period last year. Net profit amounts to EUR 12.6 million, up from EUR 7.8 million in the same period in 2005. Operating revenues increased to EUR 335 million from EUR 326 million in the same period in 2005. The results of Carl Bro are incorporated in the profit and loss account as of 1 September 2006. The market recovery in Northwest Europe led to more contracts and to a better margin. Over the first nine months of 2006 earnings per share are EUR 2.84 compared to EUR 1.93 in the first nine months in 2005 (an increase of 47%). Please note that the number of outstanding shares has increased by 400,000 in this period.

Operating revenues from continuing operations in the first nine months of 2006 increased with more than 10% to EUR 302 million (2005: EUR 271 million). Revenues are impacted by the contribution of Carl Bro. Also some adjustments (which have no impact on cash and result) in minor continuing operations have influenced the revenues. The organic growth of the continuing operations since the third quarter of 2005 amounts to approximately 3%. Third-party project expenses remained approximately the same. Result after tax of continuing operations over the first nine months is EUR 11.7 million (2005: EUR 9.4 million). In the first nine months of 2006, the margin before interest and tax for continuing operations (inclusive of third-party project expenses and holding costs) was 6.0% compared to 5.4% in the first nine months of 2005.

Result after tax of activities held for sale over the first nine months are EUR 0.9 million (2005: EUR -/-1.6 million). The related margin is 4.3%, up from -/-5.1% in 2005.

Carl Bro Integration
The Carl Bro companies are contributing to the profit and loss account as of
1 September 2006. The integration is on track. From January 2007 all companies will use the company name Grontmij.

Market developments
The market in our business sector is recovering step by step both in volume and composition, leading to better margins and capacity utilisation results. Assignments that were acquired in recent months included:

• Building: Development of Saksen Weimar military barracks complex in the Netherlands, together with other parties and consultancy and engineering services for the Military Hospital Antwerp (Belgium);
• Transportation: Widening of the Dublin ring road M50 from two to three lanes and road expansion in Helsingør in Denmark for the Danish Highway Agency;
• Environment: Handbook for waste planning for Municipalities all over Sweden and consultancy, engineering and supervision for the closing activities of a landfill (20 million m3) in Rheinland-Pfalz, Germany;
• Water: Management, maintenance and renewal of the information system of all 28 water bodies in the Netherlands (3 years);
• Industry: Framework contract engineering of industrial processes for Umicore (Belgium);
• Energy: For ABB data modelling of the power network in Sardinia in connection with building of a new undersea power link .

Divestment process
In the second quarter of 2006 various small projects and companies in the property sector were sold at their book value, leading to a reduction of activities held for sale since 31 December 2005 by approximately EUR 16 million to EUR 64 million as per 30 June 2006. The sale of capital intensive projects in Italy and the agreement to sell one of the larger Dutch divestment projects in October were a further step in the divestment process. The incoming cash flow of EUR 20 million will entirely be used for the redemption of bank loans in the fourth quarter.

Negotiations for the sale of various projects, both in the Netherlands and abroad, are fully underway. It is expected that a substantial part of the activities held for sale (net carrying amount EUR 80 million at year-end 2005) will have been sold by the end of 2006.

Outlook for 2006
In our press release given on 17 August 2006 (half year figures) we expected, in view of the development in turnover and results in the first half of 2006 and of market developments, the positive trend in results achieved in the first half of 2006 to continue for the entire year (exclusive of results of Carl Bro).

As stated before in the General Shareholders Meeting on 17 August 2006 the acquisition of Carl Bro will have a positive impact on this outlook (including the impact of interest, goodwill and dilution).
