Copper Mountain Named No. 1 of 50 Fastest-Growing Companies by Worth Magazine; Company Highlighted as a Leading Vendor for Internet Infrastructure Equipment.

PALO ALTO, Calif.--(BUSINESS WIRE)--Nov. 1, 1999--

Copper Mountain Networks, Inc., (Nasdaq:CMTN) the market share leader in business Digital Subscriber Line (DSL) equipment, today announced that Worth magazine has identified it as the fastest-growing Internet-related company in the magazine's November 1999 issue. The magazine based its ranking on revenue growth in dollar and percentage terms.

The Worth article, entitled "The Web's 50 Fastest-Growing Companies," noted that Copper Mountain, like most of the companies cited by Worth, is "in the business of building the infrastructure for the Internet of the future. While the consumer sites have gotten most of the attention so far, it's in the business-to-business arena that the Internet's greatest impact is likely to be felt." Copper Mountain develops and markets a comprehensive family of DSL solutions that enable high-speed internetworking over existing copper telephone wires, connecting offices and homes to the public telephone network.

Worth has ranked Copper Mountain No. 1 on a list that includes other cutting-edge infrastructure companies such as Redback Networks (Nasdaq: RBAK, No. 13) and Convergent Communications (Nasdaq: CONV, No. 18) as well as such consumer powerhouses as America Online (NYSE: AOL, No. 3), Amazon.com (Nasdaq: AMZN, No. 7), and eBay (Nasdaq: EBAY, No. 37).

"Our growth cited by Worth reflects the market momentum of DSL as a mainstream broadband technology for small and medium businesses," said Rick Gilbert, president and CEO of Copper Mountain. "We are actively working to maintain our momentum by continually expanding the capabilities of, and thus the market for, Copper Mountain's DSL solutions. For example, Copper Mountain's recently introduced G.lite line card expands the target market of our service provider customers beyond small and medium-sized businesses to teleworkers and technologically advanced families. Our Inverse Multiplexing solution increases DSL bandwidth from 1.5 Mbps to as much as 12 Mbps. And our support for Voice over DSL enables service providers to offer users both voice and data over one copper loop."
