Fourth Quarter Financial Results

Sales were $172 million, a decrease of 18% from $209 million in the third quarter of 2015, and a decrease of 15% from $203 million in the fourth quarter of 2014.

Fourth quarter net income was $25.5 million, or $0.48 per diluted share, compared to net income of $29.8 million, or $0.56 per diluted share in the third quarter of 2015, and $34.2 million, or $0.64 per diluted share in the fourth quarter of 2014.

Non-GAAP net earnings, which exclude special charges and credits, were $18.4 million, or $0.34 per diluted share, compared to $31.5 million, or $0.59 per diluted share in the third quarter of 2015, and $29.1 million, or $0.54 per diluted share in the fourth quarter of 2014.

Full Year Results

Sales were $814 million, an increase of 4% from $781 million in 2014. Net income was $122 million, or $2.28 per diluted share, compared to $116 million, or $2.16 per diluted share in 2014. Non-GAAP net earnings were $119 million, or $2.22 per diluted share, compared to $101 million, or $1.89 per diluted share in 2014. Cash and investments at December 31^st were $658 million, or approximately $12.37 per share. Total book value, net of goodwill and intangibles, was $917 million or approximately $17.24 per share.

Commenting on the company’s financial results, Gerald Colella, Chief Executive Officer and President, said, “The fourth quarter finished stronger than expected, as the softening we witnessed in the semiconductor market abated somewhat at the very end of the year. With 4% sales growth for the full year, we achieved a significant increase in profitability, testament to the continued improvements we have made to our target operating model. As we begin 2016, recent company reports and analyst estimates forecast a continued healthy environment in our served markets, which bodes well for continued strong financial results for MKS in the coming year.

“Based on current business levels, we expect that sales in the first quarter of 2016 may range from $165 to $185 million, and at these volumes, our non-GAAP net earnings could range from $0.25 to $0.38 per share and GAAP net income could range from $0.23 to $0.36 per share.”
