(NASDAQ:PMCS), a leading provider of high-speed broadband communications and storage semiconductors, and MIPS-Powered microprocessors, today reported results for the first quarter ending April 3, 2005. Net revenues in the first quarter of 2005 were $66.1 million, an increase of seven percent compared with $61.8 million for the fourth quarter of 2004, and a decrease of 16 percent on a year-over-year basis. Net income in the first quarter of 2005 on a non-GAAP basis was $3.9 million (non-GAAP diluted earnings per share of $0.02) compared with non-GAAP net income of $1.9 million (non-GAAP diluted earnings per share of $0.01) in the fourth quarter of 2004. GAAP net income in the first quarter of 2005 was $3.3 million (GAAP diluted earnings per share of $0.02) compared with GAAP net income of $13.1 million in the fourth quarter of 2004 (GAAP diluted earnings per share of $0.07). PMC-Sierra's first quarter included an additional week of business because 2005 is a 53-week fiscal year for the Company. For a full reconciliation of GAAP net income to non-GAAP net income, please refer to the supplemental schedule on page 6 of this release. The Company believes the additional non-GAAP measures provided are useful to investors for the performance of financial analysis. Management uses the non-GAAP measures internally to evaluate its in-period operating performance and to plan for the Company's future periods. However, non-GAAP measures are neither stated in accordance with, nor are they a substitute for, GAAP measures. "In the first quarter of 2005, we experienced improving trends in Asian geographies and a recovery in enterprise networking, wireless infrastructure, routing and laser printing as well as growth in new storage-related products," said Bob Bailey, president and chief executive officer of PMC-Sierra. "We continue to invest in growth opportunities including next-generation infrastructure that enables voice, video and data services as well as enhanced enterprise storage solutions." New products and company announcements in Q1 2005 include the following: - S/UNI(R) DUPLEX GE - we announced an ATM-to-Ethernet interworking device for IP DSLAMs that enables service providers to offer Triple Play services while lowering their development and field deployment costs. As ATM networks are migrating to Ethernet-based IP networks, service providers are deploying DSLAMs that can interface to the ATM-based CPE on one side and the Ethernet access network on the other. The S/UNI DUPLEX GE implements ATM to Ethernet conversion in dedicated hardware, a function deployed to date in expensive network processors or FPGAs. The device provides DSLAM vendors with increased bandwidth while significantly reducing their line card costs. The S/UNI DUPLEX GE provides the AAL5 SARing, queuing/buffering, traffic management, address translation, and multicast functions. - 4G Fibre Channel Interoperability - we successfully demonstrated system interoperability between our 4Gbit/s Fibre Channel (FC) Loop Switch product family with multiple FC initiator, fabric switch, and FC hard disk drive vendors at the Intel Developers Forum in March. The multi-vendor interoperability included: 4Gbit/s Fibre Channel Loop Switch products from PMC-Sierra; 4Gbit/s HDDs from Hitachi and Seagate; Initiators from Emulex and Agilent Technologies; and Fabric Switches from Brocade. PMC's architecture for 4G Fibre Channel SAN and NAS storage systems includes the CTS 20x4G, CTS 18x4G, CTS 4x4G and Storage Management Controller (SMC). This low cost, scalable architecture enables storage systems OEMs to differentiate their product offerings through innovative enclosure services, system performance and diagnostics. - maxSAS(TM) Reference System - we announced the availability of our maxSAS Reference System for fabric attached and server attached SATA/SAS disk array enclosures. The Reference System, combined with the SCSI Enclosure Services Software Development Kit, significantly reduces development costs while accelerating time-to-market for storage equipment vendors. The system utilizes PMC-Sierra's SXP 36x3G or SXP 24x3G high port count expander switches for SATA and SAS Hard Disk Drive interconnect. Both SXP devices integrate a MIPS-Powered programmable storage enclosure processor for managing the enclosure environment through the standards-compliant SES protocol.
