Management Discussion
  • restructuring, impairment and other charges, primarily related to employee termination costs. In addition, there was a $1.9 million gain from the sale of a building within the Electronics segment.
  • The first quarter of 2020 includes $1.2 million of acquisition integration charges related to the IXYS acquisition and other contemplated acquisitions. In addition, there were $4.0 million of restructuring, impairment and other charges, primarily related to impairment charges of $2.2 million associated with the announced consolidation of a manufacturing facility within the Industrial segment and $1.7 million of employee termination costs and other restructuring charges.
  • Net sales increased $117.7 million or 34.0% including $12.4 million or 3.6% of favorable changes in foreign exchange rates for the first quarter of 2021 compared to the first quarter of 2020. The increase was primarily due to higher sales of $72.3 million and $23.8 million, respectively, in the Electronics and Automotive segments driven by higher volumes across all businesses within these segments. The volume increase within the Electronics segment was led by greater customer demand for products and devices for work-from-home and stay-at-home needs, and strong global automotive demand driving an increase for products used in automotive electronics and electric vehicles. The volume increase within the Automotive segment was due to stronger global auto and commercial vehicle market demand. The remaining increase in net sales was due to $16.7 million of net sales resulting from the Hartland acquisition included in the Industrial segment.
