E.J. Elliott, Gencor’s Chairman, stated, “The road building industry in the United States has operated under eight extensions to the SAFETEA-LU since its expiration in September 2009. The current economic environment along with the short term focus and lack of commitment on the part of the current administration has caused the domestic industry to languish over the past two years. We believe that the true road back to stability, by providing the funds and programs necessary for our customers to invest in new equipment, lies in the renewal of the traditional six year Highway Bill”.

Mr. Elliott went on to say, “Over the past couple of years we have reviewed our internal processes and related cost structures, eliminating non-value added activities and investing in equipment to make us more efficient while maintaining our strong balance sheet. We continue to focus on designing and manufacturing the heaviest-built and highest quality equipment in the industry and providing superior customer service. We also continue to evaluate opportunities to expand our existing businesses, either through organic growth, or acquisition opportunities.”

Gencor Industries is a diversified heavy machinery manufacturer for the production of highway construction materials, synthetic fuels and environmental control machinery and equipment used in a variety of applications.
