Acopia Networks Closes Record Quarter; Secures Additional $20 Million in Venture Funding.

LOWELL, Mass. -- Dramatic Quarterly Revenue Growth of Over 40% Fueled by Rapid Customer Adoption of ARX Products

Acopia Networks(R), the pioneer of Adaptive Resource Networking, announced today that it achieved record results from Q1, 2006, reporting over 40% sequential quarter to quarter revenue growth, and that it has closed an additional $20 million round of funding. The round was led by Meritech Capital Partners, a premier late-stage venture capital firm and a new investor to the company.

Acopia's record quarter was driven by many new customer wins, including Yahoo!, DreamWorks, Novartis, Industrial Light & Magic, United Rentals, Massachusetts Medical Society, Iron Mountain, Hartford Insurance Group, and Wellington Management, along with continued expansion within several existing Acopia ARX(R) customers.

"Our first quarter results are a clear indication that the market for file virtualization products is well established, and that Acopia's products uniquely address the needs of large scale deployment," said Christopher P. Lynch, President and CEO of Acopia Networks. "We expect the growth rate to continue, and perhaps accelerate further as we ramp up our international business."

"Our style of investing targets late stage companies that are best in class," said Paul Madera, Managing Director, Meritech Capital Partners. "Acopia's customer growth, revenue acceleration and unique ability to provide customers with a 'freedom of choice' with their storage vendors, positions them very well for an initial public offering. We are very pleased to invest in this next phase of growth at Acopia."

Meritech Capital Partners was joined in this round by Acopia's existing investors: Accel Partners, Charles River Ventures, Goldman Sachs, Star Ventures and Vesbridge Partners. Acopia Networks, the market leader in file virtualization, has raised total financing of $85 million since its inception in January 2002.

This funding round, which was based on a significant increase in valuation, will allow Acopia to aggressively expand US and international sales efforts and scale customer support operations to meet the strong market demand for its products.
