Parsippany, New Jersey – Wireless Telecom Group, Inc. (NYSE MKT: WTT) announced today results for the fourth quarter and twelve months ended December 31, 2014.

For the quarter ended December 31, 2014, the Company reported net sales of $9.3m, compared to $9.5m for the same period in 2013, a decrease of 2%. Net sales in the Network Solutions segment were $6.2m, compared to $6.0m for the same period in 2013, an increase of 3%. Net sales in the Test and Measurement segment were $3.2m, compared to $3.5m for the same period in 2013, a decrease of 10%.

For the twelve months ended December 31, 2014, the Company reported net sales of $40.3m, compared to $33.8m for the same period in 2013, an increase of 19%. Net sales in the Network Solutions segment were $28.2m, compared to $22.0m for the same period in 2013, an increase of 28%. Net sales in the Test and Measurement segment were $12.1m, compared to $11.8m for the same period in 2013, an increase of 3%.

Non-GAAP normalized EBITDA for the three and twelve month periods ended December 31 was $0.7m and $5.6m, for 2014 and $1.3m and $4.1m for 2013, respectively. Our non-GAAP normalized EBITDA results do not include the Company’s tax provision (benefit), depreciation and amortization and stock compensation expense, as well as interest expense, rental income from a property investment, a one-time gain from the sale of such property investment, a one-time gain from the sale of an investment security and certain other costs. A reconciliation of net income to non-GAAP normalized EBITDA results is included in an attachment to this press release.

Net income for the three and twelve month periods ended December 31 was $0.3m and $2.4m or $.01 and $.11 per diluted share for 2014 and $1.3m and $3.8m or $.05 and $.16 per diluted share for 2013, respectively. Net income from 2013 benefited from the non-cash recognition of the Company’s deferred tax asset.

Paul Genova, CEO of Wireless Telecom Group, Inc. commented “In 2014, we achieved strong revenue and income growth in the Network Solutions segment. Revenues increased by 28% to $28.2m and segment income increased by 36% to $7.6m driven by our strong position in the North American DAS market as well as continued global market gains in support of the carrier network build out for LTE.”

“Consistent with industry performance, the Network Solution Q4 order flow softened due to reductions in capital spending by the major domestic carriers. While we have seen an increase in current order backlog, we expect this softness to continue in the near term. However, according to a major US Carrier, global mobile data usage will more than double by 2019, increasing the need for global investment in LTE coverage and capacity for wireless operators over the long term. We believe our Network Solutions segment is well-positioned to take advantage of this growth and expect our order flow to improve as carrier spending returns to higher levels.”

Genova continued, “In 2014, our Test and Measurement segment remained steady contributing over $1m in segment income. Additionally, we generated cash flow from operating activities of $4m and we utilized $9.6m to repurchase 4.8m shares from our largest shareholder for $2 per share. We look forward to continued execution of our strategic plan, which may include additional investments in research and development as well as pursuing any opportunities that will increase shareholder value.”
