The Company’s reporting of Non-GAAP net income excludes expenses for restructuring, gain or loss on sale of assets, stock based compensation, amortization and impairment of intangible assets and goodwill related to the Company’s acquisitions, and non-cash related income tax expense.

Non-GAAP operating margin of negative three percent in the quarter, compared to four percent in the same period last year.

Non-GAAP net loss of $494,000 or $(0.03) per diluted share in the quarter, compared to $904,000 or $0.05 per diluted share in the same period last year.

“Over the past 15 months, we took several actions to align the business with significant changes in the industry,” said Marty Singer, PCTEL’s Chairman and CEO. “These changes include carrier spending declines which impacted our small cell kitting and engineering services revenue. We are confident, though, that our investments in direct sales to infrastructure vendors and in crowd-based, cloud-based network test and measurement will result in revenue growth and profit for the remainder of 2016 and in 2017. We are particularly well-positioned to participate in the growth associated with FirstNet, utilities, fleet, and network performance engineering,” added Singer.
