"While the weak economy dragged down our efforts during the first half of the year, the Company demonstrated a strong re-bound with record revenue and net income in fourth quarter. Combining our fourth quarter success and our year-end backlog establishes a very positive trend line for the year ahead," commented Cheri Beranek, president and CEO of Clearfield. "As stated in quarterly earnings reports during the past year, the American Recovery and Reinvestment Act slowed business in the first half of our fiscal year but now represents a significant growth opportunity for Clearfield. Over the summer months, moneys have begun to flow, and Clearfield customers are beginning to deploy their networks. Among some of the early "Stimulus Award" winners are Rural Telephone, one of the largest FTTp deployments funded under the federal program and a long-standing Clearfield customer."

"The introduction of new and innovative product technologies, such as the Clearview xPAK, has launched Clearfield into new application environments, including meeting the fiber connectivity needs of cellular back-haul and business-class services among municipal/utility, wireless and cable TV providers. Technology partnerships, such as the launch of pushable fiber from Miniflex into the U.S. marketplace, expands the product suite we can provide to our current and prospective customers," continued Beranek. "Looking ahead, you can expect to see a continued focus from Clearfield to deliver next generation products that continue to reduce our customers' operating costs of delivering fiber connectivity."
