Alphen aan den Rijn (July 5, 2010) - Wolters Kluwer reiterates its guidance for the full year 2010 and medium term, based on trading conditions through May 2010. Wolters Kluwer expects organic revenue growth to be flat for the first half-year 2010 and ordinary EBITA margin to be in line with the first half-year 2009, and expects solid free cash flow. This operating performance underpins the company's confidence in reaching its previously stated full-year 2010 guidance (see table below). The company made this announcement prior to its scheduled half-year 2010 results on July 28, 2010, in light of an inadvertent release of information.

Key Performance Indicator 2010 Guidance
Ordinary EBITA margin 20-21%
Free cash flow[1] ≥ €400 million
Return on invested capital ≥ 8%
Diluted ordinary EPS[1] €1.41 to €1.45
[1] In constant currencies (EUR/USD = 1.39)

Medium-Term Outlook
Wolters Kluwer also reiterates its medium-term outlook, as stated on February 24, 2010 (see table below), supported by the shift toward higher margin electronic solutions and the additional contribution from operational excellence initiatives including the Springboard program. The company expects to deliver steadily improving operating margin, ordinary EBITA, and diluted ordinary earnings per share in constant currencies. Free cash flow is expected to be equal to or greater than €400 million per annum in constant currencies, reflecting the resilient and growing subscription base. Return on invested capital will equal or exceed 8%.
