CEO Joseph Ram said the company enjoyed record total shipments of products last year but was hurt by increased research and development, marketing, and carrier certification expenses.

“Our operating expenses included a high level of R&D spending as we invested heavily in a new line of ruggedized smartphones. The concurrent development of these models over the last two quarters required an expansion of our team,” Ram said.

Traded on the Nasdaq under IFON, shares were at 60 cents recently, giving the company a market capitalization of $8.5 million. Its 52-week range was 52 cents to $1.78.
