RF Monolithics Reports Second Quarter Results; RFM Reports Continuing Profitability and Strong Cash Flow

DALLAS--March 17, 2005--RF Monolithics, Inc. today reported net income for the second quarter ended February 28, 2005, of $221 thousand or $0.03 per diluted share compared to net income of $484 thousand or $0.06 per diluted share for the second quarter of the prior year. The Company reported sales for the second quarter of $11.3 million, equal to sales in the second quarter of the prior year.

For the six months ended February 28, 2005, net income was $628 thousand or $0.08 per diluted share compared to net income of $885 thousand or $0.11 per diluted share for the same period of the prior year. The Company's sales during the first two quarters of fiscal 2005 were $23.4 million compared to $22.4 million for the prior year's first six months.

President and CEO David M. Kirk, commented, "We reported a 5% increase in first half sales over the same six month period of last year. The decrease in net income from the prior year was primarily due to our decision to invest more heavily in research and development. Unfortunately, the strength of demand we saw coming into this fiscal year appears to have slowed considerably in several of the wireless component markets we serve, resulting in sales that were softer this quarter than last quarter. In spite of this, we believe it was a good performance quarter. In meeting our guidance, we improved gross profit margins; we reported positive operating cash flow of $1.8 million; and we had net profit of $0.03 per share.

"This quarter we also began the next phase of our strategic plan with the expansion of our Mission Statement to include all low-power wireless solutions for automotive, consumer, industrial, medical and communications markets. We are known in the industry for our radio frequency (RF) expertise and for helping our customers incorporate our components and modules into their applications. We intend to use this expertise to be more market focused and provide more complete wireless solutions to our customers. Our plan is to rapidly expand our potential available markets by doing this.

"With the addition of a VP of Marketing to drive market penetration and our new product initiatives, we launched our newly created Wireless Solutions Group. The focus of this new group is to offer a wide range of products and services for delivering small area wireless solutions for industrial, commercial, medical, transportation, security, and consumer applications. We believe this next step of our strategic plan is a key factor to our continued successful growth."

Mr. Kirk further commented, "The ramping from the first half of the year to the second half that we experienced last year is not evident this fiscal year. Economic growth in many of the wireless component markets we serve, particularly automotive, has temporarily slowed. On a more positive note, our diversification allowed us to report a one-to-one book-to-bill ratio this quarter, while many of our competitors are reporting significant reductions in bookings and flat sales. As a result of the economic outlook, lack of a final ruling on the tire pressure monitoring legislation, and our very limited visibility of customer requirements, we are guiding to third quarter sales remaining flat to slightly up from our second quarter. This would be down from the exceptionally strong third quarter we experienced last year. The product mix of our bookings this quarter has shifted toward products experiencing the strongest pricing pressures. In spite of this, we believe we will hold our margins in the 29% to 30% range through continued cost reduction efforts. Our third quarter operating expenses will be up marginally as we continue our product development efforts. We expect to continue to generate a positive operating cash flow."

Quarter Highlights:

-- The Company reported a one-to-one book-to-bill ratio for the quarter despite signs of softening in many wireless components sectors.

-- For the six months ended February 2005, the Company reported 5% sales growth over its prior year's first half.

-- The Company reported another quarter of strong filter sales and bookings activity which reflects continued growth in the satellite radio application.

-- The Company achieved a 30.2% gross profit margin, despite significant average selling price decreases from the prior year resulting from competitive conditions. Ongoing cost reductions offset most of this impact and was the primary reason for the slight increase from 29.5% in its first quarter.

-- The Company continues to report positive operating cash flow of approximately $1.8 million for the quarter and a cash position of $4.7 million.

-- In its efforts to increase its presence in Asia, the Company opened a sales office in Taiwan.

-- The Company strengthened its management team with the appointment of Joe Andrulis as Vice President Marketing and head of the Company's new Wireless Solutions Group.

-- The Company successfully conducted its fiscal year 2004 annual shareholders meeting. All issues put before the shareholders were approved and management's presentation to the shareholders is available on the investor relations section of the Company's website (www.rfm.com).
