Losers

The company said it recorded third quarter sales of about $225 million, lower than last year's $278.79 million, while Street predicted $250.21 million. The company had expected to report third-quarter sales of $250 million. RF Micro Devices said its Cellular Products Group's third-quarter sales was about $179 million, as demand for 2G components from China-based customers for entry-level handsets failed expectations. In Multi-Market Products Group, revenue was about $46 million, reflecting weakness in end markets. Additionally, the company said it expects gross margin for the quarter to decline about 9 points sequentially, due to the lower revenue, pared factory utilization, and inventories. Looking ahead into the fourth quarter, the company said it expects normal seasonality in the handset industry and in Multi-Products Group's end markets.

The company said the reduced expectations for revenue and earnings in 2012 were the result of the soft performance in the fourth quarter of 2011, a stronger dollar compared to the Euro, international economic risk, and slightly lower growth expectations for the domestic extremity product lines.

Additionally, Integra said it received a warning letter from the United States Food and Drug Administration (FDA) related to quality systems and compliance issues at its collagen manufacturing facility located in Plainsboro, New Jersey.

Since the conclusion of the inspection in late August, 2011, Integra said it had undertaken significant efforts to remediate the observations that the FDA has made and that it continues to do so.
