Commentary- Cheryl Beranek, President & CEO of Clearfield

"We are very pleased with our 50% revenue growth for this quarter and year-to-date period. Our success is based upon increasing acceptance of our FieldSmart® fiber management architecture and FiberDeep^TM fiber connectivity solutions throughout our customers' network. The product line continues to earn acceptance from small and large accounts alike. Networks, such as those at Venture Communications in South Dakota with a thousand access lines to Cincinnati Bell's network of 150,000 fiber lines and growing, demonstrate the scalability of our platform. Core to our success is the personal relationships we are building with the engineers responsible for these networks, but we are also pleased with the strong reseller partnerships we are building with distributors and original equipment manufacturers that enable us to reach an even broader base of business.

"While the projects funded through the American Recovery and Reinvestment Act's stimulus program are an important part of our strategic plans, the business generated under this program remains a minority of our revenue for the third quarter of 2011.

"Engineering and product management remains aggressive with new product initiatives. Last quarter's introduction of the FieldSmart Small Count Delivery (SCD) Case showcases the innovation of our product development efforts. This product line is changing the way drop cable media is deployed introducing Clearfield to expanding market opportunities as we bring fiber closer and closer to the home.

"We are continuing to increase our manufacturing capacities, with additions in production headcount, capital equipment and facility build-outs. Our team of production and manufacturing personnel is doing a stellar job of responding to our accelerating growth demands while improving our productivity levels.  Key to our gross margin growth is continual improvements in the manufacturing process which are reducing our overall cost of production. Teamed with supply partnerships that ensure the availability of our product components, we remain confident that we can control our growth in required inventory while meeting the increasing demand being generated by our sales and marketing teams.

"We are continuing to reduce the average time between customer order and product delivery. Delivering our product line with a guaranteed delivery date is winning the Company business and enabling our customers to maintain deployment schedules that reduce installation costs.

"The increase in operating expenses over the prior year reflects our investments into building our sales team, along with higher compensation expenses associated with the achievement of revenue and income objectives. Over the upcoming months, we will continue to invest in personnel with additions in our sales, marketing and engineering talent. While it will be crucial for us to remain focused, we are confident that we can leverage our value-based business model into new accounts within our foundational business as well as emerging revenue-generating market segments."
