Greatbatch, Inc. announced preliminary earnings results for the year ended December 28, 2012. For the year, the company's preliminary revenue increased approximately 13.5% over the prior year to $645 million driven primarily by the acquisition of MicroPower, a provider of portable medical solutions, in December 2011. Preliminary 2012 Adjusted Operating Margin and Adjusted Diluted EPS are in line with previously discussed guidance of the lower-end of 11.5% to 12.5% and $1.75 to $1.85 ranges, respectively, as a result of expense management during the year and a decrease in estimated incentive compensation payout.

The company also provided earnings guidance for the year 2013. For the year, the company's total sales are expected to be in a range of $660 million to $680 million, an increase of 2% to 5% primarily driven by growth in the Portable Medical and Vascular product lines. Adjusted operating margin is targeted to be 12.0% to 12.5%. Adjusted diluted EPS growth is expected to be in the range of $1.90 to $2.00, an increase of 7% to 13%. Adjusted effective tax rate includes only the 2013 benefit of the recently reenacted R&D Tax Credit to be in a range of 33% to 35%.
