· Commissioned an extrusion line in Zanesville, OH to increase manufacturing capacity, bringing a total of 5 extrusion lines across 2 facilities

Steve Silverman, President and CEO of AXION said, “Overall 2013 was a period of change and progress. We executed our plan to bring manufacturing in house, while increasing our manufacturing capacity. We also made huge strides to become a vertically integrated and diversified manufacturer with the acquisition of assets of a re-processor of recycled plastic products. This transformation has enabled us to control quality, stabilize costs, improve margins and increase revenues.”

Silverman further commented, “Sales exceeded our expectations in 2013 and our margins increased due to a more normalized revenue mix and less concentration of sales with our largest Class I rail customer. The launch of our heavy construction mat is on schedule and we saw sales pick up in the 4^th quarter with increased sales activity as we head into the spring months. Our existing customers are acknowledging our infrastructure products’ wide ranging advantages and are recognizing our consistent quality and seeing AXION as a world class manufacturer. Our pipeline and large international business development projects continue to grow and are on schedule. Strategically, we have taken a step to become a vertically integrated supplier with a diversified business that reduces overall supply chain costs in bringing our recycled engineered products to market. We have a high degree of confidence that 2014 will provide even greater returns for our shareholders.” Silverman added.
