AVX Corporation Announces Preliminary Second Quarter Results

FOUNTAIN INN, S.C. – October 24, 2018 -- AVX Corporation (NYSE: AVX) today reported preliminary unaudited results for the second quarter ended September 30, 2018.

Chief Executive Officer and President, John Sarvis, stated, “We completed the second quarter of our fiscal year with net sales of $456.3 million, reflecting an increase over both the previous quarter and the same quarter in the prior year. Market conditions continued to be strong, resulting in healthy product demand in most of the markets we serve. Our gross profit of $126.5 million, or 27.7 percent, reflects solid operating performance, positively influenced by our operational efficiency programs, as well as an improved pricing trend in the market. Our distribution channel continues to experience favorable trends and reflect a positive outlook for succeeding quarters. While difficult to predict, we continue to be optimistic that demand for our electronic components and interconnect, sensing and control devices will remain strong during the remainder of the fiscal year.”

For the three and six month periods ended September 30, 2018, net sales were $456.3 million and $910.4 million, respectively, compared to net sales of $352.7 million and $684.0, respectively, for the same period last year. The increase in net sales for the three and six month periods ended September 30, 2018 reflect increased sales of $89.4 million and $187.1 million, respectively, in our Interconnect, Sensing and Control segment attributable to our acquisition of the AB Electronics sensing and control business and $31.8 million and $63.7 million, respectively, 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 $1.4 million for the quarter ended September 30, 2018, as compared to $85.2 million for the same period last year, and $18.6 million for the six months ended September 30, 2018, as compared to $162.0 million for the same period last year.

Operating profit for the three month period ended September 30, 2018 was $85.6 million compared to $44.8 million for the same period last year. Operating profit for the six month period ended September 30, 2018 was $153.7million compared to $87.2 million for the same period last year.

Net income for the quarter ended September 30, 2018 was $72.1 million, or $0.43 per diluted share, as compared to net income for the quarter ended September 30, 2017 of $34.8 million, or $0.21 per diluted share.

Net income for the six month period ended September 30, 2018 was $128.0 million, or $0.76 per diluted share, as compared to net income of $66.3 million, or $0.39 per diluted share, for the six month period ended September 30, 2017.

Chief Financial Officer, Michael Hufnagel, stated, “In keeping with our long-term strategy, we continue to maintain our strong financial position allowing flexibility for investments in acquisitions, materials, equipment and people to support the long-term growth of the Company. As of September 30, 2018, we had cash, cash equivalents and short-term investments in securities of approximately $844.7 million, and no debt. We continued to provide value to our stockholders during the quarter by paying $19.4 million in dividends to stockholders.”
