GCT Semiconductor Raises $20 million in Series D Funding

New funding underscores investor confidence in the Company's proprietary
RF CMOS design expertise for use in ICs for current and next-generation mobile handsets.

December 13, 2004 - San Jose, CA -- GCT Semiconductor, Inc., a leading provider of highly integrated semiconductor solutions for wireless communications, today announced the closing of its $20 million Series D round of financing. Led by Samsung Venture Investment Corporation (SVIC), the round also includes strategic investment from UTStarcom, Inc., with both companies investing after careful evaluation of GCT's product portfolio. Other investors in this round include East Gate Capital, Bokwang Investment Partnership, AT Ventures, KGI Partners, and Nexus Investment Corp. Two of the Company's primary financial investors, Parakletos Ventures and Pequot Capital, also participated in the financing.

The new capital will be used to continue expansion of the Company's manufacturing capabilities and to ramp up for production volume manufacturing of the Company's PHS and GSM/GPRS radio-frequency (RF) transceivers for worldwide markets. In addition, the funds will be used to continue development of innovative new products based on GCT's proprietary complementary metal-oxide semiconductor (CMOS) RF technology, specifically focusing on the mobile handset markets for second and third-generation mobile wireless systems, including W-CDMA and EDGE.

Jay Eum, Managing Director of Samsung Ventures America, who will join GCT's board of directors, stated, "Our strategic investment in GCT Semiconductor represents Samsung's view that RF CMOS represents the way of things to come in RF transceiver design, and GCT Semiconductor's leading edge RF competencies today will pave the way for tomorrow's ever demanding cost effective mobile handsets."

"We are very pleased with the successful closing of this round of financing, which is evidence of investors' strong confidence in our RF CMOS technology for mobile handsets. Already, our RF transceiver ICs have been designed-in to several of our strategic partners' applications," commented Dr. Kyeongho Lee, President and CEO of GCT Semiconductor. "We believe this new investment will allow us to strengthen these strategic relationships as well as rapidly expand our global mobile handset business."
