NEW YORK (TheStreet) -- Shares of Summit Materials (SUM) - Get Report were gaining on heavy trading volume Wednesday afternoon after the company posted better-than-expected earnings for the 2016 third quarter.

Before today's opening bell, the Denver-based construction materials company reported adjusted earnings of 73 cents per diluted share, higher than Wall Street's projections of 71 cents per share.

Revenue for the quarter was $480.2 million, below analysts' forecasts of $483.2 million.

"Sustained organic growth in aggregates and cement pricing, coupled with improved cost discipline and margin capture, contributed to significant year-over-year increases in operating cash flow and net income in the third quarter," CEO Tom Hill said in a statement.
