Amsterdam (July 21, 2008) - Wolters Kluwer, a leading global information services and publishing company, today reiterated its 2008 full-year earnings per share, operating profit margin, free cash flow, and return on invested capital guidance. Full-year organic revenue growth outlook is adjusted from 4% to 3% due to impact of recent market conditions in non-subscription product lines. In light of the current volatility and uncertainty in the financial markets, Wolters Kluwer is announcing the full-year outlook ahead of the scheduled publication of half-year results on July 30, 2008.

Highlights
Adjustment of 2008 full-year organic revenue growth guidance from 4% to 3%

Nancy McKinstry, CEO and Chairman of the Executive Board, commented on the company's future growth prospects:

"While the underlying profitability of the business remains strong and we reiterate all other key performance indicators, the impact of recent market conditions in our non-subscription products lines, particularly within Corporate & Financial Services, require that we adjust full-year organic revenue growth expectations. Importantly, the fundamentals of our recurring revenue business remain on track with stable margins, improving retention rates, growth in higher margin online and software solutions, and efficiencies resulting from prior restructuring initiatives. These fundamentals are driving margin growth, strong cash flow, and double-digit earnings growth.

We are confident that the foundation is in place for sustained profitability and long-term growth around our strategy of serving professionals with innovative information, software and services. We continue to invest in growth and manage the business for the long term. Our strong balance sheet allow us to seize attractive growth opportunities."
