Under generally accepted accounting principles (GAAP), net revenues for the fourth quarter were $11,506,000, up slightly from $11,492,000 in the previous quarter and down 11% from $12,967,000 in the comparable period last year. Net loss for the quarter was $370,000, or ($0.01) per share, compared to a net loss of $631,000, or ($0.02) per share, in the previous quarter and versus a net loss of $694,000, or ($0.03) per share, in the comparable period a year ago. For the twelve months ended June 30, 2003 net revenues were $44,958,000, down 6% from $47,589,000 in the previous fiscal year. For the twelve months ended June 30, 2003, net loss was $4,327,000 or ($0.17) per share as compared with a net loss of $5,267,000 or ($0.21) per share in the previous fiscal year. Pericom management believes pro forma financial information is useful to investors because it illuminates the underlying operational trends by excluding significant non-recurring or otherwise unusual transactions. The following results reflect certain pro forma adjustments for the three-month period ended June 30, 2002 and the twelve-month periods ending June 30, 2002 and June 30, 2003. There were no pro forma adjustments for the June 2003 or March 2003 quarters. The amount and nature of these pro forma items are explained in the reconciliation of pro forma and GAAP financial results that appears in the financial statements portion of this release. On a pro forma basis, net revenues for the fourth quarter were $11,506,000, up slightly from $11,492,000 in the previous quarter and down 11% from $12,967,000 in the comparable period last year. Pro forma net loss for the fourth quarter was $370,000 or ($0.01) per share compared to a pro forma net loss of $631,000, or ($0.02) per share, in the previous quarter and a pro forma net loss of $118,000, or ($0.00) per share, in the comparable period last year. For the twelve months ended June 30, 2003 pro forma net revenues of $44,958,000 were down 12% from pro forma net revenues of $50,807,000 for the previous fiscal year. Pro forma net loss for the twelve months ended June 30, 2003 was $2,739,000, or ($0.11) per share, as compared with pro forma net loss of $473,000, or ($0.02) per share, for the twelve months ended June 30, 2002. Alex Hui, President and Chief Executive Officer of Pericom said, "The business environment continues to be challenging. The timing of a sustained global economic recovery remains elusive. We are committed to a number of major programs that are key to our growth strategy, although the timing of the ramp to volume production is difficult to predict. Many of these opportunities involve our new product offerings that are being well received across multiple product lines and markets. Our confidence in the future is supported by a strong balance sheet with ample cash reserves, an excellent customer base, an increasing product portfolio and technical capabilities augmented by our pending acquisition of Saronix LLC, strong presence in Asian markets, and sufficient operating capacity." NEW PRODUCTS The company developed 10 new products during the quarter aimed at key server, notebook, networking, and communication markets. Eight of these products were proprietary. -- Pericom began sampling to industry leading PC Notebook and PC peripheral suppliers a new USB 2.0 switching solution as part of Pericom's Silicon Switch product line. The USB 2.0 product introductions reinforce Pericom's commitment to provide industry leading Application Specific Switching solutions. -- Complimented our Clock product line with a 500MHz, low jitter, and low skew PLL clock generator targeted toward the networking space. -- We rounded out our LVTC product offering by introducing 4 new 8-bit logic products. These new products along with our previously introduced 16 bit LVTC products offer Telecom and Networking customers a lower power equivalent performance solution to replace high power consuming BiCMOS LVT based logic. -- We continue to enhance our leadership position in Register Logic and Clock drivers for the DDRI and DDRII memory market used in Server platforms. The PI74SSTU32864 register and PI6CU877 PLL clock products continue to be well received by Tier 1 and Tier 2 DIMM memory module suppliers. This market is expected to gain further momentum in 2004 as Server platforms migrate from DDRI-333 MHz memory modules to DDRII-400 MHz memory modules. SEPTEMBER 2003 QUARTER OUTLOOK -- We entered the September quarter with less backlog than the previous quarter, and are thus dependent on a higher level of turns to achieve a flat sequential quarter. Indications are that turns will occur later in the quarter, therefore with low turns visibility at this time our revenue guidance range is between $10.0 million and $11.0 million. -- Gross margin should remain in the 30% range but continues to be highly dependent on product mix and pricing. -- Operating expenses are expected to increase slightly. -- Other income will be approximately $1.0 million. Pericom will adhere to Regulation Fair Disclosure. The company will provide its investors and analysts with guidance in the areas of total revenues, gross margin, operating expenses and other income each quarter in our earnings releases and in our conference calls. We will not provide further guidance or updates during the quarter unless we do so via a press release. NOTE: Our Fourth Quarter Results telephone conference call will begin at 1:45 p.m. PDT today.
