In a particular country, there is only a single natural gas provider. Due to a government anti-trust regulation, this natural gas provider has been forced to price so that at least 90% of the country will buy gas.

One year, the country decides to deregulate the natural gas provider and allow them to price as they desire. As a result, the provider raises prices substantially and collects higher profits than before. Which of the following can be concluded about the natural gas provider?
