Last month MRP affirmed its forecast for annual earnings growth of 27 percent to $498 million in the year ending June 30, 2014.
The company's shares were unchanged at $2.025 in trading yesterday, and have dropped 19 percent from the $2.50 offer price in the May float. MRP embarked on a share in October as a means to prop up the price.
