Exhibit 99.1 Rogers Corporation Raises Guidance for the Fourth Quarter ROGERS, Conn.--(BUSINESS WIRE)--Jan. 9, 2006--Rogers Corporation (NYSE:ROG) today announced revised guidance for its fiscal fourth quarter ending January 1, 2006. Rogers projects fourth quarter net sales to be approximately $97 million compared to the October 19, 2005, guidance of $85 to $88 million. Earnings for the fourth quarter are projected to be $0.52 to $0.54 per diluted share versus previous guidance of $0.40 to $0.44 per diluted share. "This increased guidance results from our ability to capitalize on our strong market position, which led to an acceleration of sales during the fourth quarter," commented Robert D. Wachob, President and CEO. "In our Printed Circuits business, both high frequency and flexible circuit material product lines had strong sales. The High Performance Foams business sales continued at near record levels, driven by the PORON(R) urethane foams product line. Of our three businesses, Polymer Materials and Components is expected to show the greatest quarterly improvement, due to the success of the DFLX(TM) flexible keypad lamp for cell phones. Lastly, our joint ventures are also expected to post increased contribution, driven by strong sales." The Company expects to report the fourth quarter and full year results in February, and will provide guidance for the first quarter 2006, at that time.
