As the market leader, A1 Telekom Austria AG is classified as a provider with substantial market power in Austria and is therefore subject to the corresponding regulatory measures. These include extensive network access and price regulations. The international subsidiaries of the Telekom Austria Group are also subject to far-reaching regulatory provisions in their respective national markets. The relevant regulation for A1 Telekom Austria AG in the fixed-line network applies at retail and wholesale levels, including access obligations to allow alternative providers access to infrastructure and services. However, decisions on regulation are not just made at a national level, but are increasingly also being made at a European level. For example, this is the case for the European Commission roaming regulation, which applies equally to all EU member states.
