Motorola has announced that its fourth quarter sales and profits were lower than forecast.
Sales for the second largest mobile phone manufacturer are expected to reach between $11.6 billion and $11.8 billion (up to £6 billion) because of a lower demand for handsets. The company had forecast sales of $11.8 billion to $12.1 billion (up to £6.2 billion).
About 66 million Motorola handsets were shipped during the period, up 23 per cent on the previous quarter.
"We are very disappointed with our fourth quarter financial performance, but we remain committed to the strategic direction and long-term financial targets we discussed at our annual analysts meeting," said chief executive Ed Zander.
Motorola has seen disappointing sales in the past six quarters. A rise in handset sales has not translated to higher profit for the group, with larger competition and the availability of cheap handsets restricting prices for the brand and reducing their profit margin.
