Comtech Telecommunications Corp. Wednesday posted lower sales and net income for the quarter ended Oct. 31 on weakness in its telecommunications transmission business.

Net income was $1.4 million, or 9 cents per diluted share, versus $5.2 million, or 32 cents per diluted share, in the year-earlier period.

The company maintained its fiscal 2016 revenue guidance of $300 million to $310 million.

Stanton Sloane, president and chief executive, said in a statement that the $430.8 million acquisition of Maryland-based TeleCommunications Systems Inc. announced in November will improve the company’s outlook.

“I believe that the acquisition of TCS is a turning point for Comtech and I am excited about the growth opportunities that are ahead of us,” he said.

Shares of Comtech were at $20.90 in after-hours trading following the earnings release.
