RF Monolithics Reports Fourth Quarter 2005 and Fiscal Year Results; Company Avoids Major Adverse Effect from Delphi Bankruptcy

DALLAS--Oct. 1, 20053, 2005--RF Monolithics, Inc. today reported sales for the fourth quarter ended August 31, 2005, were $11.5 million compared with sales of $12.5 million in the fourth quarter of the prior year and sales of $11.3 million reported for the third quarter of fiscal year 2005. Sales for the year ended August 31, 2005, were $46.2 million compared with sales of $48.5 million for the year ended August 31, 2004.

Net loss for the fourth quarter ended August 31, 2005, was $202,000, or a loss of $0.03 per diluted share, compared to net income of $559,000, or $0.07 per diluted share, for the fourth quarter of the prior year. Net income for the year ended August 31, 2005, was $484,000 or $0.06 per diluted share, compared to the net income of $2.2 million or $0.27 per diluted share for the prior year.

David M. Kirk, President and CEO of RF Monolithics, Inc., commented, "Our fourth quarter profitability was affected by Delphi Corporation's recent filing of reorganization under Chapter 11 of the Bankruptcy Code. Delphi is a major customer representing almost 12% of sales in the quarter. In order to fully reserve against our receivable exposure, we recorded $135,000 in additional reserves for the quarter. Delphi expects operations will continue to go forward as scheduled and we have minimized our financial exposure for fiscal year 2006. Apart from Delphi, a significant order for our higher-margin Virtual Wire(TM) product was moved out of the quarter due to customer delays in the roll out of a major program which we offset with short lead-time consumer orders received and filled within the quarter. These offsetting sales were generated by our low-power components and filter products which have lower gross profit margins. Also, in order to extend a multi-year purchase contract with an increase in market share and acceptance of a new product, we accelerated reduced pricing for a major customer resulting in lower revenue and gross profit for the quarter. The over-all effect of these events on the quarter was a gross profit margin of 26.5% instead of the 29-30% gross profit margin we had anticipated.

"For the year, sales were down almost 5% from last year, primarily due to factors affecting the automotive market. Automotive production schedules for our major end users were down approximately 12% this year. We also had anticipated the TREAD ACT Regulations would have a more positive near-term effect on the demand for tire pressure monitoring, or TPM, devices. The effect of the final ruling was to delay implementation of the requirements to install TPM. These factors, combined with the ongoing decline in sales for mature products, not only eliminated the growth we had anticipated for the year, but effectively resulted in a 19% sales decline in our automotive market. Fortunately, we are not solely dependent on the automotive market and our 33% growth in the consumer market and the 38% increase in the Automated Meter Reading application in our industrial market nearly offset the automotive decline.

"In fiscal year 2006, we expect to see significant sales increases in TPM-related products as a result of the TREAD ACT. We believe that Satellite Radio subscriptions will continue to be strong, resulting in corresponding strong sales activity for our filters in this application. We expect growth in the medical market with the recent approval of our Virtual Wire(TM) product in a major application in this area. We also see a lot of potential for our new Wireless Systems products as wireless sensor applications in the industrial market grow toward the potential 2010 target of five billion dollars."

Mr. Kirk further commented, "For our first quarter of fiscal 2006, we expect sales to be up slightly compared to this quarter as we return to a more traditional product mix with less dependence on our components. We are expecting our gross profit margin to be in the 28% to 30% range. Considering the impact product mix has on our gross profit margin, going forward we expect to guide to a wider range rather than specific margins. Our operating expenses are also expected to be up slightly, as we continue to fund our strategic business plan. We will also recognize the non-cash impact of stock compensation for the first time under FAS123(R) of approximately $170,000."

Quarter/Annual Highlights:

-- Year-over-year sales declined approximately 5% due almost entirely to reductions in automotive production schedules during the year. The decline was somewhat offset by strong filter sales into Satellite Radio applications and very solid sales throughout the year in the industrial markets.

-- Backlog at year-end of $10.5 million, down 11% compared to the prior year end, reflects reduced automotive production and continued pressure for shorter lead-times, particularly in the consumer market.

-- Operating cash flow for fiscal year 2005 was $3.9 million and for the fourth quarter was $300,000, continuing to improve our cash position. We saw reductions in both receivables and inventory despite increased sales in our fourth quarter.

-- We received approval for a medical application which has been in development for the past two years. The application requires long battery life, small foot print and proven reliability which made our Virtual Wire(TM) product the ideal wireless solution. We expect scheduled shipments will begin in the first half of fiscal year 2006.

-- During the quarter, we announced FCC certification of the first mesh-enabled low-power module. Using extremely low-power microcontroller technology, the module can be programmed to operate for years without changing the battery.

-- During the quarter, we announced the formation of RFM Technologies, Inc., a wholly owned subsidiary, that will be a vehicle to assist RFM in carrying out its strategic plan to assemble wireless solutions with products, technologies and applications composed of a wide range of radio modules, gateways, wireless sensor networks, point-to-point and mesh network protocols with development tools.

-- We continued our commitment to quality and corporate responsibility as demonstrated by recent certification under ISO/TS16949:2002 international automotive quality standards and ISO 140001 environmental system standards as well as our compliance with the European Union's Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS).
