RF Micro Devices Updates Fourth Quarter Business Outlook

RF Micro Devices Updates Fourth Quarter Business OutlookCompany Anticipates Sequential Revenue Growth in June Quarter

Conference Call Scheduled for April 14, 2005 at 5:00 p.m. Eastern Time

GREENSBORO, N.C., April 14 /PRNewswire-FirstCall/ -- RF Micro Devices, Inc. (Nasdaq: RFMD), a leading provider of proprietary radio frequency integrated circuits (RFICs) for wireless communications applications, announced today that it will host a conference call on April 14 at 5:00 p.m. Eastern Time to discuss updated financial guidance based on preliminary unaudited results for its fiscal 2005 fourth quarter ended March 31, 2005.

Based upon the preliminary review of unaudited financial results, RF Micro Devices currently anticipates its revenue for the March 2005 quarter will be approximately $150 million, which represents the low end of the range provided by the Company on January 25, 2005. In addition, the Company currently anticipates that GAAP and pro forma per share results will be adversely impacted by lower-than-anticipated gross profit, resulting from increased inventory reserves and efforts during the quarter to reduce the value of the Company's inventory. The Company also anticipates that its financial results will be adversely impacted by greater-than-anticipated product development expenses, related primarily to the Company's efforts to speed time to market for its POLARIS™ TOTAL RADIO™ modules, its next-generation cellular transceivers and its world-leading power amplifier (PA) modules. These factors are in addition to the anticipated effect of the discontinuation of the Company's wireless local area network (WLAN) chipset development efforts, announced on February 28, 2005.

RF Micro Devices currently expects that its net loss per share for the quarter ended March 31, 2005 will be approximately ($0.33) to ($0.34) per share on a GAAP basis and approximately ($0.08) to ($0.09) per share on a pro forma basis. The pro forma results exclude the effects of the previously announced discontinuation of the WLAN chipset development efforts, deferred compensation and intangible amortization and an accounting correction related to lease expenses for prior periods, which amount to approximately ($0.22), ($0.01) and ($0.01) per share, respectively. In its January 25, 2005 earnings release and conference call, the Company had previously forecasted a GAAP net loss per share for the March quarter of approximately ($0.03) to ($0.04) and a pro forma net loss per share for the March quarter of approximately ($0.01) to ($0.03).

Dean Priddy, chief financial officer of RF Micro Devices, commented, "The Company's quarterly revenue will be within the range of our previous guidance, driven by growth in EDGE cellular transceivers and infrastructure products, relative flatness in wireless connectivity and a seasonal decline in cellular PAs. The inventory reserves taken this quarter were related primarily to three products. Two of the products - our first-generation POLARIS™ 2 transceiver and our first-generation PowerStar® PA - have been succeeded by next-generation products, while the third - our WLAN 802.11g transceiver - experienced less-than-anticipated demand. Additionally, we believe the Company's efforts to reduce inventory levels and significant price reductions from several key suppliers will benefit margins in future periods. In terms of expenses, we responded to our customers' requests to expedite several key products, including our industry-leading, highly integrated POLARIS™ TOTAL RADIO™ module, which enables our customers to bring out smaller, more highly integrated products and also provides RFMD with higher content per handset. These products are now expected to commence mass production in the second half of 2005.

"We currently anticipate June quarterly revenue and gross margin will increase sequentially," Priddy concluded.

Bob Bruggeworth, chief executive officer of RF Micro Devices, commented, "While we are disappointed in our results for the quarter, we are pleased to have executed on a number of key new product initiatives. During the March quarter, RF Micro Devices shipped its market-leading POLARIS™ 2 Total Radio™ transceiver into a growing portfolio of EDGE handsets. We achieved sequential growth in POLARIS™ 2 transceiver shipments, despite normal seasonality in the handset market.

"The Company is positioned well for its upcoming fiscal year. The handset industry continues to adopt next-generation air interface standards, such as EDGE and WCDMA, and RFMD's cellular power amplifiers command greater than 50% market share in both standards. RFMD is also the leader in merchant market EDGE transceivers, having shipped greater than 4 million units to date. The Company continues to expect it will increase its content in handsets this year as we launch transmit modules and our POLARIS™ Total Radio™ module solutions."
