Ultralife Corporation Reports Third Quarter Results

NEWARK, N.Y. – October 27, 2016 -- Ultralife Corporation (NASDAQ: ULBI) reported operating income of $1.1 million on revenue of $19.6 million for the third quarter ended September 25, 2016. For the quarter ended September 27, 2015, the Company reported operating income of $1.2 million on revenue of $19.0 million.

“Successful execution of the strategy to diversify beyond our core U.S. government/defense business while abiding by our business model parameters produced solid third quarter results,” said Michael D. Popielec, President and Chief Executive Officer. “Although weak economic conditions continued to constrain revenue growth, we delivered operating income for the third quarter that was more than double the second quarter, and profitability for the eighth consecutive quarter. We also remain poised to achieve profitable growth for 2016. Finally, we continue to build resources to support investments in organic and inorganic growth opportunities through greater operating leverage and inventory reductions.”

Third Quarter 2016 Financial Results

Revenue was $19.6 million, an increase of $0.6 million, or 3.1%, compared to $19.0 million for the third quarter of 2015 reflecting the addition of Accutronics and higher Communications Systems sales partially offset by lower core Battery & Energy sales. Battery & Energy Products sales declined to $14.9 million compared to $16.4 million last year due primarily to lower sales to a large U.S. government/defense OEM and lower 9-Volt sales, partially offset by higher medical sales, the contribution of Accutronics, and a large shipment to a non-U.S. government/defense customer. Communications Systems sales grew 76.6% to $4.7 million compared to $2.7 million for the same period last year reflecting shipments under the Vehicle Installed Power Enhanced Riflemen Appliqué (“VIPER”) Program.

Gross profit was $6.0 million, or 30.5% of revenue, compared to $5.9 million, or 31.0% of revenue, for the same quarter a year ago. Battery & Energy Products’ gross margin was 30.3%, compared to 29.1% last year, an increase of 120 basis points reflecting favorable product mix including the contribution of Accutronics. Communications Systems’ gross margin declined to 31.4% compared to 42.4% for the prior year primarily due to sales mix.

Operating expenses were $4.9 million compared to $4.7 million last year reflecting the addition of Accutronics, partially offset by certain cost reduction actions along with continued tight control over discretionary spending. Operating expenses were 24.8% of revenue equal to 24.8% of revenue for the year earlier period.

Operating income was $1.1 million compared to $1.2 million last year for an operating margin of 5.8% compared to 6.2% last year.

Net income was $1.0 million, or $0.07 per share, equal to net income of $1.0 million, or $0.07 per share, for the third quarter of 2015.
