E.J. Elliott, Gencor’s Chairman, commented, “Bookings in the first quarter of fiscal 2013 were certainly negatively impacted by the uncertainties of the Presidential election, and the turmoil over the ensuing fiscal and tax policies in the United States. As a result, contracts were signed too late in the quarter to positively impact our first quarter’s revenues. This, coupled with the year-end drop in equities markets compounded the less than satisfactory first quarter results. Currently, our factories are operating at full capacity with a healthy backlog, and the financial markets have already shown recovery.”

Mr. Elliott continued, “We fully expect the highway construction industry will improve over time, but over the near-term we do not foresee an increase above that of recent years. I am optimistic that as the industry recovers, Gencor will be a major beneficiary by providing the best technology, value and service to our markets. The Company’s financial position remains very strong and we will continue to evaluate opportunities for growth while investing further in R&D, product engineering and manufacturing efficiencies and improvements.”

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