MELBOURNE, Florida, April 29, 2014 — Harris Corporation (NYSE:HRS) reported revenue in the third quarter of fiscal 2014 of $1.27 billion and income from continuing operations of $137 million, or $1.27 per diluted share. In the prior year, revenue was $1.20 billion and income from continuing operations was $125 million, or $1.12 per diluted share. Orders in the third quarter were $1.11 billion compared with $1.13 billion in the prior year.

“Third quarter revenue and earnings were higher than the prior year as a result of strong performance in Government Communications Systems and RF Communications’ international tactical radio business,” said William M.

Tactical Communications revenue was $335 million, increasing 21 percent, and Public Safety revenue was $122 million, decreasing 14 percent. Segment operating income was $144 million compared with $116 million in the prior year.

Orders for the segment totaled $405 million, including $285 million in Tactical Communications and $120 million in Public Safety. Book-to-bill was 0.89 for the segment, and funded backlog was $680 million in Tactical Communications and $578 million in Public Safety.

International tactical radio orders included $82 million and $49 million from two countries in Asia.
