Mohawk Industries ( MHK) rose 6% Friday after second-quarter earnings rose 21.9%. The Calhoun, Ga.-based carpet maker earned $119.5 million, or $1.76 a share, in the quarter, compared with $98.1 million, or $1.45 a share, a year ago. Analysts polled by Thomson First Call were expecting earnings of $1.55 a share in the most recent quarter. Second-quarter revenue rose 26.7% to $2.06 billion as against analysts' estimate of $2.05 billion. The growth was helped by the Unilin acquisition, total hard surface sales growth, internal growth, price increases and new patent licenses, the company said. The company forecasts its third-quarter earnings at $1.76 a share to $1.85 a share as against analysts' estimate of $1.80 a share. "I am pleased with our second quarter performance, especially in light of the economic and industry factors we are facing. Hard surface growth and higher selling prices positively affected our sales while replacement demand for carpet remains slow," the company said. "The change from LIFO to FIFO inventory accounting removes some uncertainty in predicting future results." Shares rose $4.02 to $69.89.
