“We’re pleased with our sequential quarterly sales and profit improvements,” said Rich Wasielewski, Nortech Systems’ president and CEO. “After several quarters of working through customer inventory issues, it was good to see contributions across the board.” He noted that Nortech’s overall quarterly backlog increased nine percent, both sequentially and year over year,

with all three markets — medical, industrial and defense — providing momentum heading into the second half of the year.

Gross margin in the second quarter of 2018 was 13.4 percent, an improvement of 190 basis points sequentially and 220 basis points compared to the prior-year period. The strong gross margin performance resulted from a favorable product/service mix, cost reductions and process improvements.

“Our industry continues to face tariff concerns and electronic component shortages,” concluded Wasielewski, adding that these issues may become even more challenging in the second half of the year. Nortech estimates it was unable to ship $0.6 million in customer orders in the second quarter due to component shortages.
