Market risks relating to the Galapagos shares

We have identified the following major market risks:

• Possible volatility of share price
  The market price of the shares might be affected by a variety of factors outside management control, such as the global economic situation, the business development of competitors, sector mergers and acquisitions; it is difficult to mitigate this risk.

• Economic risk due to failure in confidence
  General public confidence about future economic conditions or performance of us or our suppliers or customers may impact the ability or willingness of others to trade with us.

• Dilution through capital increases
  Raising additional capital may cause dilution to our existing shareholders. By raising additional capital through capital increases with cancellation of the preferential subscription rights of our existing shareholders, these shareholders will be diluted.

• Dilution through exercise of subscription right plans
  The exercise of existing subscription rights can significantly increase the number of outstanding Galapagos shares.

• Inability to distribute dividends
  We have a limited operating history and future profitability cannot be guaranteed. Galapagos NV has significant losses carried-forward and will thus not be able to distribute dividends in the near future. This can cause people to refrain from investing in Galapagos shares.

• Reputational damage
  High ethical standards are maintained throughout the entire organization at all levels. Laws and guidelines are complied with. Our suppliers are required to adhere to contractual terms which include anti-bribery and anti-corruption provisions. In addition, our external consultants are required to comply with our Code of Business Conduct and Ethics and U.S. Foreign Corrupt Practices Act Policy.

• Belgian law provisions
  There are several provisions of Belgian company law and certain other provisions of Belgian law, such as the obligation to disclose important shareholdings and merger control, that may apply to us and which may make an unfriendly tender offer, merger, change in management or other change in control, more difficult. These provisions could discourage potential takeover attempts that third parties may consider and thus deprive the shareholders of the opportunity to sell their shares at a premium (which is typically offered in the framework of a takeover bid).
