Eckert said in a statement. "Additionally, we are enjoying better than expected results from Preheat, Inc., our most recent acquisition that provided us with additional equipment leasing capabilities." Barring any unexpected weather or permit delays, the improved performance trend could continue through the remainder of 2006, the company said. Shares of Omni climbed 57 cents, or 5.6%, to $10.70.
