PLX Technology to Acquire Teranetics

SUNNYVALE, CA - PLX Technology, Inc. [NASDAQ: PLXT], the leader in connectivity solutions for the data center and the home, today announced it has signed a definitive merger agreement to acquire all of the outstanding shares of capital stock of Teranetics, Inc., a privately held fabless provider of high-performance mixed-signal semiconductors. Teranetics, the broadly recognized leader in 10 Gigabit Ethernet over copper physical layer (10GBase-T PHY) technology, delivered the industry’s first fully integrated single-chip implementation of single-port and dual-port 10GBase-T PHY silicon. This silicon is the only known solution in production today.

Teranetics’ corporate headquarters are located in San Jose, California. Founded in 2003, Teranetics provides state-of-the-art silicon solutions that enable 10 Gigabit rates over widely installed low-cost CAT6 and CAT6a cabling. Teranetics’ products allow data centers and enterprise networks to increase scalability and improve throughput while dramatically lowering the cost of ownership for 10 Gigabit links.

Significant growth is expected over the coming years as 1 Gigabit Ethernet networks are upgraded to 10 Gigabit. Market leaders of enterprise switches, NICs, and adapters are shipping products today with Teranetics’ 10GBase-T products. As servers start to ship with 10GBase-T on motherboards next year, demand will accelerate. The Linley Group estimates that over four million ports will ship in 2012 and over 22 million ports in 2014. The total potential for this market is much greater and will take years to develop, similar to the transition from Fast Ethernet to 1 Gigabit Ethernet. Today, 1 Gigabit Ethernet is dominant in the data center, with over 200 million switch ports shipping annually.

PCI Express and 10G Ethernet have their advantages and will continue to coexist as complementary technologies in the data center. PLX will leverage its unique leadership position, technology and IP with these two dominant IOs to bring out new architectures for the data centers of tomorrow and to tap further into the $2 billion Ethernet semiconductor market. These future solutions can take advantage of both technologies while leveraging the company’s superior switching fabrics, high-speed analog, and SoC capabilities to increase performance, lower power consumption and reduce overall system costs.

“This acquisition installs a third leadership position into our product portfolio,” said Ralph Schmitt, president and CEO of PLX. “As the market leader, Teranetics has successfully solved difficult system issues with 10 Gigabit Ethernet plaguing the data center. This has allowed them to ramp their products at critical customers. PLX is fully committed to this market and will continue to invest in future PHYs and other IP to bring high-performance system-level products to market. We welcome our new team to the PLX family, where we will share our mutual core values of leadership, excellence, integrity and winning.”

Under the terms of the merger agreement, PLX Technology will acquire Teranetics in exchange for 7.4 million shares of PLX valued at approximately $27.6 million based on today’s closing price, cash of approximately $1.3 million and two promissory notes aggregating approximately $6.9 million. PLX will also assume approximately $18 million of Teranetics corporate obligations, including indebtedness, transaction expenses incurred by Teranetics and cash bonuses payable to Teranetics employees. The first note will be for $5.4 million due one year from closing and the second will be for approximately $1.5 million due three years from closing. The acquisition has been approved by both companies’ boards of directors. The acquisition, which is subject to satisfaction of certain closing conditions, is anticipated to be completed in early October 2010. Prior to signing the merger agreement, PLX also made a $1 million bridge loan to Teranetics.

“By joining forces with PLX, an established leader in server and data center connectivity, Teranetics gets the framework essential to scaling our business and strengthening our ability to win,” said Nersi Nazari, president and CEO of Teranetics. “With our combined portfolios of enterprise PCI Express switches and 10G Ethernet PHYs, and our common customer base, we envision the newly merged company dominating the backbone of the data center market.”
