Peter R. Chase, Chairman and Chief Executive Officer, commented, “We were able to continue to improve profitability significantly in the third fiscal quarter compared to the previous year along with modest revenue growth. A strong focus on consolidation and reduction of overlapping expenses in manufacturing, selling and administration continues to produce positive results.

“Industrial revenues were down slightly with a pullback in demand for some of our wire and cable products offsetting increases in electronic coatings.

“Construction materials were very strong led by Middle East projects in the pipeline area and robust C.I.M. sales. Bridge and highway product sales were short of plan and prior year due to a slower start to the construction season and resulting project delays.

“The ERP implementation project is on track to be completed by the end of the calendar year, R&D spending is steady and our M&A program is continuing to explore both buy and sell opportunities.

“We are optimistic about the future, finishing FY 2014 successfully, and getting off to a strong start in FY 2015.”
