We are confident that we are well positioned to capitalize on an economic recovery.”

Notable items include the following:

-Earnings per diluted share of $1.13 compared with $1.23

-Net sales increased to $443.7 million compared with $428.3 million

• Heritage aggregates product line volume up 6.3 percent for the quarter

• Specialty Products record third-quarter earnings from operations of $12.0 million

“The infrastructure end-use market, which had volume growth of 3 percent, was supported by an increase in state transportation spending that was somewhat offset by a decline in shipments to projects funded by the American Recovery and Reinvestment Act (ARRA), a.k.a. “the stimulus”). “We continue to believe that this is a timing issue since stimulus-related projects contributed volume growth in some states during the quarter. In other states, principally Iowa, where they aggressively completed their stimulus-related work in 2009, our shipments actually declined.”

Overall, However, aggregates shipments to the infrastructure end-use market, excluding projects funded by ARRA, increased more than 6 percent, Nye notes.
