PRAGUE--Czech financial company PPF said Monday it had decided not to bid for a license to operate a fourth-generation mobile telephone network due to a new condition in the process set by the telecommunications regulator.

PPF's withdrawal has boosted the share price of dominant operator Telefonica Czech Republic (BAATELEC.PR), a unit of Spain's Telefonica SA (TEF), as it removes the threat of well-financed competition.

Radek Stavel, a spokesman for privately held PPF, said the company had decided to withdraw from the auction because the Czech Telecommunications Office, or CTU, "set an unprecedented condition that effectively prevents a new company from gaining access to the domestic telecommunications market."

The condition prevents a new player in the market from partnering an existing operator that is also participating in the auction for 15 years, PPF said.

As a result, PPF has sold its fledgling telecom unit PPF Mobile Services AS, Mr. Stavel said.

Monday is the last day that interested parties can submit non-binding expressions of interest in bidding in the auction for new long-term-evolution, or LTE, frequencies among others.

The CTU, which aims to introduce a fourth operator to the market through the tender, will announce the names of the companies that are interested in bidding in the auction on Tuesday. Binding bids are expected in the second half of November.

The two other operators active in the Czech republic are a local unit of Vodafone Group PLC (VOD), and T-Mobile Czech Republic, a unit of Germany's Deutsche Telekom AG (DTE.XE).

At 0935 GMT, Telefonica CR shares were up 2.7% at 300 koruna ($15.76), outperforming the broader Prague market, which opened lower.
