AVX Corporation Announces Preliminary Fourth Quarter and Fiscal Year Results

FOUNTAIN INN, S.C. – April 22, 2019 -- AVX Corporation (NYSE: AVX) today reported preliminary unaudited results for the fourth quarter and fiscal year ended March 31, 2019.

Chief Executive Officer and President, John Sarvis, stated, “We completed our fiscal year with net sales of $1,791.8 million, reflecting a 14.7 percent increase over the previous year. Our gross profit of $482.9 million, or 27.0 percent gross profit margin reflects solid operating performance, positively influenced by our operational efficiency programs, as well as improved pricing in the market when compared to the prior fiscal year. We continue to focus on providing our customers with the value added electronic components and interconnect, sensing and control devices they require in today’s sophisticated electronic products as well as our continued commitment to cost control in our operations. We are making necessary investments in manufacturing plant expansion and product line increases to support our customers’ growing requirements. We continue to be optimistic that demand for our electronic components and interconnect, sensing and control devices will remain strong during the next fiscal year.”

For the quarter and fiscal year ended March 31, 2019, net sales were $439.0 million and $1,791.8 million, respectively, compared to net sales of $446.6 million and $1,562.5 million, respectively, for the same periods last year. The increase in net sales for the fiscal year ended March 31, 2019 reflect sales of $354.7 million, in our Interconnect, Sensing and Control segment attributable to our acquisition of the AB Electronics sensing and control business and $113.3 million in our Electronic Components segment attributable to our acquisition of Ethertronics, Inc. The increased sales were partially offset by the loss of Kyocera resale product sales which were $19.0 million for the fiscal year ended March 31, 2019, as compared to $296.3 million for the fiscal year ended March 31, 2018.

Operating profits for the quarter and fiscal year ended March 31, 2019 were $76.5 million and $319.7 million, respectively, compared to operating profits of $47.3 million and $179.8 million for the three and twelve month periods ended March 31, 2018, respectively.

Net income for the quarter ended March 31, 2019 was $69.5 million, or $0.41 per diluted share compared to net income for the quarter ended March 31, 2018 of $31.8 million, or $0.19 per diluted share.

Net income for the fiscal year ended March 31, 2019 was $271.8 million, or $1.61 per diluted share. Net income for the fiscal year ended March 31, 2018 was $4.9 million, or $0.03 per diluted share, reflecting one-time tax charges of approximately $129.4 million related to the U.S. tax reform law signed in December 2017 and an enacted income tax rate reduction in France.

Chief Financial Officer, Michael Hufnagel, stated, “Our continuing long-term strategy is to maintain our financial position in order to allow flexibility for investments in acquisitions, materials, equipment and people to support the long-term growth of the Company. As of March 31, 2019, we had cash, cash equivalents and short-term investments in securities of approximately $813.2 million and no debt. We continued to use our resources to provide value to our stockholders during the fiscal year by paying $77.6 million in dividends.”
