Westell Technologies Fiscal 2011 First Quarter Highlights

Westell Technologies Reports Profit of $0.07 per Share

AURORA, IL, July 21, 2010 – Westell Technologies, Inc. (NASDAQ: WSTL), a leading provider of broadband products, outside plant telecommunications equipment and conferencing services, today announced results for its fiscal 2011 first quarter ended June 30, 2010. Total revenue for the quarter was $41.3 million, down 23% from $53.5 million in the fiscal first quarter of the prior year. Net income during

the quarter was $4.6 million, or $0.07 per diluted share, compared to net income of $2.0 million, or $0.03 per diluted share, in the same quarter of the prior year. Total cash and cash equivalents were $61.8 million at June 30, 2010, up $0.5 million during the quarter. Share repurchases during the quarter totaled approximately 247,000 shares at a cost of $0.4 million.

“Although total revenues declined year-over-year, they increased on a sequential basis, and we experienced strength in the more profitable areas of the business,” said Chairman and CEO Rick Gilbert. “Gross margins were strong, and we maintained stringent cost control, even while we modestly increased product development efforts in Outside Plant Systems and Customer Networking Solutions.”

Fiscal First Quarter Segment and Consolidated Results

The Customer Networking Solutions (CNS) segment reported revenue of $15.0 million in the first quarter of fiscal 2011, down 48% compared to $28.6 million in the same quarter of the prior year. The largest impact on revenue came from lower sales of the Company’s UltraLine Series3 gateway product, which were $1.9 million in the quarter, compared with $13.4 million in the same quarter of the prior year. In spite of the significantly lower revenue, CNS gross profit was down only $0.2 million, with gross margin rising to 23.9%, compared with 13.1% in the prior-year quarter. CNS gross margin benefited from a more profitable product mix, including $0.9 million of higher-margin software revenue related to customer projects. Operating expenses dropped by $1.3 million, compared with the prior-year quarter. As a result, the CNS operating results improved to a loss of $0.4 million for the quarter, compared with a loss of $1.5 million in the same quarter of the prior year.

Revenue in the Outside Plant Systems (OSP) segment was $15.7 million in the quarter, up 14% compared to $13.8 million in the same quarter of the prior year. OSP revenue benefited from strong demand for its products that service the wireless backhaul market. Fiscal 2011 first quarter gross profit increased $0.9 million as a result of increased sales and stable gross margins, and operating expenses increased $0.6 million, to produce operating income for OSP of $3.7 million, up $0.3 million versus the same quarter of the prior year.

Conference Plus (CP) revenue was $10.5 million in the quarter, down 5% compared to $11.1 million in the same quarter of the prior year. Gross profit decreased by $0.3 million on stable gross margins, and operating expenses were $0.8 million lower, resulting in operating income of $1.4 million, up $0.5 million versus the same quarter of the prior year.

On a consolidated basis, fiscal first quarter revenue of $41.3 million was $12.3 million lower than in the same quarter of the prior year. Gross profit increased $0.4 million, and gross margins were 37.8%, compared with 28.4% in the same quarter of the prior year. Operating expenses decreased $1.6 million, compared with the same quarter of the prior year. Income taxes provided a benefit of $0.5 million in the quarter, compared to an expense of $0.2 million in the prior-year quarter. These changes drove a $2.6 million improvement in consolidated net income, which was $4.6 million, compared with $2.0 million in the same quarter of the prior year.

“This is our fifth consecutive profitable quarter – and our highest quarterly operating income since September 2006,” continued Gilbert. “It gives us a great start to our fiscal year.”
