IEC Announces Third Quarter Results for Fiscal 2013

Newark, NY – August 8, 2013 – IEC Electronics Corp. (NYSE MKT: IEC) announced its results for the fiscal third quarter ending June 28, 2013.

For the quarter ended June 28, 2013, the Company reported revenue of $35,154,000, and net income of $382,000 or $0.04 per diluted share. This compares to revenue of $36,022,000, and net income of $1,843,000 or $0.18 per diluted share for the quarter ended June 29, 2012.

IEC reported revenue of $101,824,000 and a net loss of ($863,000) or ($0.09) cents per diluted share for the first nine months of fiscal 2013. This compares to revenue of $107,900,000 and net income of $5,108,000 or $0.51 per diluted share for the first nine months of fiscal 2012.

W. Barry Gilbert, Chairman of the Board and CEO, stated, “While revenue and earnings are down from the same quarter last year, we made quite a bit of progress from the $1.1 million loss in the second quarter. This sequential improvement was delivered in spite of approximately $1.1 million of legal and accounting costs associated with the restatement of our financial information. We expect to have additional legal and accounting charges. Nonetheless, we expect our fiscal Q4 to show stronger sales and earnings than fiscal Q3.

“I am very pleased that we continue adding new customers and programs across our operations; two are military and aerospace, three are medical and several are industrial accounts. All these customers represent multi-billion dollar organizations seeking a higher level of technical capability and support than their current supplier offers. We expect to see some benefit from these new customers in about six to nine months.

“It is important to provide some texture with respect to the slight reduction in sales compared to last year, the margin change and the lack of debt reduction for the quarter. Last year one of our large industrial customers was introducing a new product and we were given the opportunity to handle virtually all of their assemblies. As discussed at the time, the margins were extraordinary. Their historic practice, as is common in our industry, is to have two suppliers for key programs. Once the program was underway they dual sourced the assembly for this product and volume returned to more normal levels. In addition, we had a medical customer that was in the last stages of an FDA recall and once that spike in production volume was over, their volume and margins also returned to more normal levels. Both of those volume reductions were largely offset by increased business from our new telecom customer. The telecom customer’s volume has steadily increased over the last three quarters, however for a long time the product was unstable and we absorbed a lot of costs. At this juncture our actions are targeted to improving efficiency which will take some time now that the number of engineering changes and supply chain issues have been substantially reduced.

“During the quarter we used our cash to purchase inventory to support shipments for our fourth quarter and to support the significant costs associated with the restatement. Our debt has increased and it is our goal to reduce our debt over the next twelve months.

“We made progress in the third quarter and believe that maintaining a long run perspective about our business is the best way to succeed in creating future value for our shareholders and opportunity for our employees.”
