Westell Technologies Fiscal 2012 Fourth Quarter Highlights

Westell Technologies Reports Fourth Quarter and Full Year Results

Revenue of $11.3 million, GAAP EPS loss of $0.04, non-GAAP EPS loss of $0.01 in the quarter

AURORA, IL, May 16, 2012 – Westell Technologies, Inc. (NASDAQ: WSTL), a leading provider of telecommunications equipment for wireline, wireless and home networks, today announced results for its fiscal fourth quarter and year ended March 31, 2012. Results reflect the sale in the fiscal 2012 first quarter of certain assets of the Customer Networking Solutions (CNS) division. Results also reflect the sale in the fiscal 2012 third quarter of the Conference Plus (CP) division, which is included in discontinued operations.

Consolidated revenue from continuing operations for the quarter was $11.3 million, down 71% compared to $38.5 million in the fiscal fourth quarter of the prior year. Consolidated revenue from continuing operations for the 2012 fiscal year was $69.7 million, down 53% compared to $147.8 million in the prior year. Revenue from the CP division is excluded from continuing operations. The declines resulted primarily from the CNS sale transaction.

Net loss in accordance with U.S. Generally Accepted Accounting Principles (GAAP) for the fiscal 2012 fourth quarter was $2.4 million, or a net loss of $0.04 per share, compared to net income of $55.6 million, or $0.79 per share, in the fourth quarter of the prior year. Fiscal 2012 results reflect tax adjustments, including adjustments to the valuation allowance against deferred tax assets. Prior year results include a tax benefit of $53.2 million for the release of valuation allowance against deferred tax assets.

Adjusting for the CNS and CP sales transactions, the Company’s statutory tax rate and other factors, non-GAAP net loss for the fiscal 2012 fourth quarter was $0.5 million, or $0.01 per share, compared to non-GAAP net income of $2.5 million, or $0.03 per share in the fourth quarter of the prior year.

Net income for the 2012 fiscal year was $42.0 million, or $0.62 per share, compared to net income of $67.9 million, or $0.98 per share, in the prior year. Fiscal 2012 net income includes after-tax gains of $19.0 million and $20.5 million from the CNS and CP sale transactions, respectively. Fiscal 2011 results include release of a $53.2 million valuation allowance against deferred tax assets. Non-GAAP net income for the 2012 fiscal year was $0.7 million, or $0.01 per share, compared to non-GAAP net income of $14.5 million, or $0.21 per share, in the prior year.

The Company repurchased 2.1 million shares at a cost of $4.8 million during the fiscal fourth quarter. Repurchases during the full fiscal year totaled 6.6 million shares at a cost of $17.4 million. As of March 31, 2012, there was $12.5 million remaining for share repurchases under the Company’s board authorization. Total cash and short-term investments at March 31, 2012 were $142.7 million.

“We benefited from a modest rebound in the markets for our core products,” said Chairman and CEO Rick Gilbert. “Compared with the fiscal third quarter, we saw marked improvement in fuse panels, custom systems integration and related enclosures. We also see promise for new products in areas like industrial Ethernet, components for distributed antenna systems, and cell-site optimization, and we remain focused on organic product development and acquisitions to drive growth in wireline and wireless markets.”

Fiscal Fourth Quarter Division Results

The Company renamed its OSPlant Systems division as the Westell division to help emphasize Westell’s focus on a broader array of products, including wireless products. Revenue for the Westell division was $10.7 million in the fiscal fourth quarter, down 29% compared to $15.2 million in the same quarter of the prior year, but up 40% compared to $7.7 million in the fiscal third quarter. Fiscal fourth quarter customer demand improved from the severely depressed levels in the fiscal third quarter, despite some customers continuing to work through inventories or otherwise curbing spending. Demand for mountings, enclosures, fuse panels and custom systems integration services improved during the fourth quarter. Sales of network interface units and similar products were up slightly but continue to be constrained by a technology shift from T1 to Ethernet.

Fiscal fourth quarter gross profit for the Westell division was $4.2 million, compared to $6.3 million in the same quarter of the prior year. Gross margins were 39.1%, compared to 41.8% in the prior-year quarter. The lower gross profit and gross margins reflected lower revenues, lower overhead absorption and changes in product mix. Operating expenses increased $0.7 million as a result of costs to develop new products, reallocation of shared costs following the CNS sale transaction, and a restructuring charge related to the consolidation of certain Canadian operations that commenced in February 2012. The division reported fiscal fourth quarter operating income of $0.3 million, compared to operating income of $3.2 million in the same quarter of the prior year.

The CNS division recorded revenues of $0.6 million in the fiscal fourth quarter, compared to $23.3 million in the same quarter of the prior year. During fiscal 2012, the division largely completed its wind-down of sales to its remaining customer following the CNS sale transaction. Product sales essentially have ceased, and remaining revenues relate primarily to software and services, which are also expected to cease during fiscal 2013.

CNS gross profit was $0.2 million, compared to $3.5 million in the prior-year quarter. Gross margin was 36.0% for the fiscal fourth quarter, up from 15.2% in the same quarter of the prior year. Operating expenses declined to $0.8 million for the quarter, compared to $4.2 million in the prior-year quarter. Ongoing expenses are focused on the Homecloud^TM project. As a result, CNS posted an operating loss of $0.6 million in the quarter, compared to an operating loss of $0.7 million in the prior-year quarter.

On a consolidated basis, operating expenses for the fiscal fourth quarter include unallocated costs which totaled $1.0 million, compared to $1.2 million in the fourth quarter of the prior year.
