- Cheryl Beranek, President & CEO of Clearfield

"Revenue growth of more than 25% resulted in a record third quarter for the company.  What's more, revenue growth for our competitive local exchange carrier (CLEC) group outpaced the rest of the company, achieving a growth rate of 37% for the quarter. A strong gain in gross margin resulted in achievement of gross margin percentage of 42.8% for the third quarter. As outlined last quarter, this rebound in gross margin percentage was expected and exceeded our target zone."

"While early in its lifecycle, the FieldSmart Makwa fiber distribution hub is shipping. The industry's first and only FDH optimized for both above and below grade deployment is changing the landscape of the OSP network. We are excited to be showcasing this product to service providers planning some of the industry's largest FTTH deployments."

"FieldShield pushable fiber continues among our fastest growing product line. Unlike airblown-fiber, pushable fiber does not require significant investment in expensive blowing equipment. Service providers that we are working with are utilizing the product for not only last mile drop solutions within FTTH projects, but also within the wireless markets as a backhaul solution."  

"We are several years into the extensive product testing process for Telcordia certification. Most of those tests for the termination of optical cable types and connector types are complete, but ongoing verification will be a continual process. In addition to the third-party work that we have done to-date, positive feedback on the quality and need for our product lines from our target service provider customers has prompted us to expand our investment into on-site test labs moving forward."

"We believe the revenue rate of growth experienced this quarter as compared to the prior year third quarter will climb in the fourth quarter. The increase in backlog as of June 30, 2015 as well as recent bookings and revenue indications received from both of the incumbent local exchange carrier (ILEC) and CLEC customer groups supports Clearfield's outlook of a strong fourth quarter. However, due to the nature of our build-to-order business as well as our industry-leading short lead-times, a more definitive outlook for the year will not be issued."
