German semiconductor firm Infineon Technologies AG (IFX.XE) Tuesday countered market speculation that it has lost its contract as sole supplier for Apple Inc.'s (AAPL) iPhone, a company spokesman said Tuesday.

"We have lost no contract," a spokesman said.

The speculation had sent Infineon shares sharply lower, but they recovered somewhat after the company's comment.

At 0933 GMT, Infineon shares were down 3.9% at EUR3.25.
