Underlying losses for the 2011 year expected to be £4.7m against £0.95m a year ago
Wolfson ended the 2011 financial year with a loss of s4.55 million for the fourth quarter against a loss of s0.63 million a year earlier.
The Edinburgh-based company said it expects full year revenues to be s99.1 million, down slightly from s99.3 million the previous year.
However, underlying losses for the 2011 year are expected to have risen to s4.7 million against s0.95 million a year earlier.
Operating losses for the year are also expected to have more than doubled to s15.2 million against s7.14 million last year.
Despite sizeable losses in the fourth quarter of 2011, Wolfson's operational summary for the full year shows revenue growth in mobile phones, PC/tablet computers and gaming rose by approximately 33 per cent, 90 per cent and 25 per cent respectively.
Wolfson said the launch of 24 new products last year, including the world's first HD Audio System-on-Chip (SoC) and a record 382 new design-ins (products designed based on Wolfson components) will contribute to 2012 revenues.
The company's audio chips are also being adopted by the likes of Samsung, LG Electronics, Sony Corp,Amazon Lab 126 and Research In Motion, which are expected to add incremental revenue in the 2012 year.
However, the company warned it expects to post a weak first quarter of trading for the 2012 year before it sees the benefit from design-ins and product launches.
Commenting on the results, chief executive, Mike Hickey, said: "Last year was characterised by strong first half growth, followed by a weak second half, resulting in flat year-on-year revenues for 2011.
"We delivered a record year for design-ins driven in part by establishing technology leadership over our competitors in the fast growing smartphone and tablet markets.
"Looking ahead, favourable technology trends coupled with the right products, customers and markets are improving the fundamentals of the business.
"These factors, plus record design-ins with leading brands, position the Company well to achieve a step-up in revenues as 2012 progresses, along with a return to both top line growth and underlying profitability."
Hickey is facing pressure from shareholders to justify the firms high overheads when the company is continuing to post losses.
Analysts Peel Hunt have suggested Wolfson would need to generate s25 million more in revenues to justify current running costs.
