* Net Sales from Continuing Operations for 4Q06 Were $307 Million, Up 5% from 4Q05;

* Year-Over-Year Sales Growth Driven Primarily by 12% Growth in Global Fiber Connectivity Solutions, 5% Growth in Global Copper Connectivity Solutions, 10% Growth in Global Enterprise Connectivity Solutions, and 17% Growth in Professional Services Partially Offset By Lower Wireless and Wireline Access Sales;

* $0.38 GAAP Earnings Per Share from 4Q06 Continuing Operations (Includes an Addition for a Net Tax Benefit Partially Offset by a Deduction for Various Net Charges);

* Total Cash Provided by Operating Activities from Continuing Operations Was $39 Million

MINNEAPOLIS -- ADC (NASDAQ:ADCT, www.adc.com) today announced results for its fourth fiscal quarter ended October 31, 2006 prepared in accordance with generally accepted accounting principles (GAAP). The results are summarized below for ADC and its two operating segments, Broadband Infrastructure and Access, and Professional Services, on a continuing operations basis.

"In the face of challenging market conditions, we achieved year-over-year sales growth of 5% in the fourth fiscal quarter of 2006," said Robert E. Switz, president and CEO of ADC. "We remain focused on achieving profitable growth and positioning ADC well for the future by: (1) Delivering innovative solutions to help our customers reach their goals of being more effective and efficient broadband communications providers; (2) Building ADC into the leading global network infrastructure company through achieving business execution excellence, competitive cost transformation and balanced sales growth; and (3) Investing to grow ADC through organic and inorganic value-creating activities in fiber, enterprise and wireless infrastructure, as well as in fast-growing regions, such as Asia."

Continued Progress Increasing Cash Flow

"In our fourth quarter, we generated $39 million of total cash provided by operating activities from continuing operations for a cumulative $94 million in fiscal 2006," said Gokul Hemmady, ADC's chief financial officer. "This fiscal 2006 result is a significant improvement compared to $70 million in fiscal 2005."

Diluted EPS Calculation

The calculation of GAAP diluted EPS from continuing operations includes the if-converted method, which assumes that ADC's convertible notes are converted to common stock, if such treatment is dilutive. This method results in the fully diluted EPS calculation for continuing operations using a:

* Numerator equal to the sum of income from continuing operations plus the addback of after-tax interest expense from the convertible notes. The convertible notes consist of $200 million in 1.0% fixed rate notes maturing on June 15, 2008 and $200 million in variable rate notes maturing on June 15, 2013, with an interest rate equal to 6-month LIBOR plus 0.375%. The interest rate for the variable rate notes will be reset on each June 15 and December 15. The interest rate on the variable rate notes is 5.795% for the six-month period ending December 15, 2006.

* Denominator equal to weighted average common shares outstanding for basic EPS plus employee stock options (where dilutive) plus 14.2 million shares assuming the convertible notes are converted to common stock.

If adjusting GAAP earnings for the certain expenses (benefits) in the above table, the variables below may be used in determining adjusted diluted EPS from continuing operations, with and without the if-converted method to determine which is the most dilutive treatment to use.

Broadband Infrastructure and Access

Comparing fourth quarters of 2006 and 2005 on a year-over-year basis, 2006 BIA sales of $255 million were 2% higher than 2005, driven primarily by sales growth of 12% in global fiber connectivity, 5% in global copper connectivity and 10% in global enterprise connectivity. This growth was partially offset by decreased sales in wireless access systems and, to a lesser extent, wireline access systems. Global fiber connectivity sales for central-office infrastructure were strong, and fiber-to-the-x (FTTX) deployments grew as well, although by a smaller amount than central-office fiber sales. Sales of global copper connectivity solutions grew as a result of demand for ADC's products that support the copper infrastructure in wireless, digital subscriber line, and fiber-to-the-node and -curb networks. Global enterprise connectivity sales increased as a result of improved infrastructure investment in the private sector. Wireless access sales, as expected, were lower by 50% compared to 2005 due to the timing of new products and reduced customer demand for existing products. Wireline access sales were down 17% due to a decline in market demand for high-bit rate digital subscriber line products as carriers undertake product substitution by delivering fiber and Internet Protocol services closer to end-user premises.

BIA sales in the fourth quarter of 2006 decreased 13% from the third quarter of 2006. Sales of global copper connectivity solutions fell 5%, global fiber connectivity sales declined 32% and global enterprise connectivity sales were down 2%. Global copper connectivity sales decreased as a result of decreased cabinet sales in Europe and merger activity among customers that ADC believes reduced demand for copper products to support central-office infrastructure and access deployments. Global fiber connectivity sales decreased primarily due to lower demand for FTTX products as a result of seasonality and customers' high inventory levels, as well as a more modest decline in fiber sales for central-office infrastructure. Global enterprise connectivity sales decreased as a result of construction seasonality. Wireless access sales, driven by the same year-over-year factors described above, decreased 6%. Wireline access sales increased 5% due to typical seasonality in the fiscal fourth quarter.

Professional Services

On a year-over-year basis, Professional Services' fourth quarter 2006 sales of $52 million increased 17% over 2005, primarily as a result of higher sales in both the United States and Germany. On a quarterly sequential basis from the third quarter of 2006, Professional Services sales in the fourth quarter of 2006 increased 3%, primarily as a result of higher sales in Germany partially offset by lower sales in the United States. In the United States, higher year-over-year sales were primarily due to a customer resuming and expanding its network build programs, and lower sequential sales were primarily due to merger activity among customers. Higher sales in Germany were primarily due to contract timing with various customers.

Other GAAP Data & Related Statistics

Below are summarized certain ADC balance sheet and cash flow information on a GAAP basis and related statistics:

[TABLE OMITTED]

ADC's total cash, cash equivalents and available-for-sale securities (short- and long-term) were $562 million as of October 31, 2006. The increase from both July 28, 2006 and October 31, 2005 was primarily a result of cash provided by operating activities from continuing operations. ADC believes that the remaining cash and securities balance is sufficient to meet anticipated needs for executing our near-term business plan. ADC's $200 million of fixed rate convertible notes outstanding do not mature until June 15, 2008, and the $200 million of variable rate convertible notes do not mature until June 15, 2013. All convertible notes have a conversion price of $28.091 per share. In addition, ADC's deferred tax assets, which are substantially reserved at this time, should reduce its income tax payable on U.S. taxable earnings in future years.

[TABLE OMITTED]

Employees

Total employees were approximately 8,600 as of October 31, 2006 compared to approximately 9,100 on July 28, 2006 and approximately 8,200 as of October 31, 2005. The decrease from July 28, 2006 was primarily the result of reducing the workforce in Mexico and the United States in response to variations in demand and cost reduction actions. The increase from October 31, 2005 was primarily the result of increasing the workforce in Mexico due to increased sales and movement of production from the United States to Mexico.

Outlook for 2007 Annual Guidance and Information on Long-term Business Direction

ADC is continuing to provide annual numeric guidance with qualitative information on the long-term direction of its business.

"The strategic fundamentals of our business continue to be solid, and we remain committed to strategically managing our business for long-term growth and profitability," said Switz. "We believe that we have significant long-term growth opportunities ahead of us, but our near-term visibility into the timing of these opportunities remains cloudy due primarily to market uncertainties. These uncertainties about our opportunities include how long it will take our customers to reduce current excess FTTX inventory levels, as well as how long and to what degree spending by our customers will be deferred during regulatory reviews and integration of customers' mergers. Regulatory reviews involve both consolidation of significant customers in the United States and the deployment of FTTX networks outside the United States. The timing and extent of our growth opportunities are unclear until these uncertainties are resolved."

In fiscal 2005 and 2006, ADC's sales fluctuated from quarter to quarter, something that may continue. ADC expects sales in our first fiscal quarter of 2007 to be down from the fourth quarter of 2006 by around 15% due to the timing issues noted above. In addition, the sequential percentage increase of sales in the second quarter of 2007 from the first quarter may be less than in comparable quarters in fiscal 2005 and 2006 depending on when the current timing uncertainties are resolved. Assuming that these uncertainties are favorably resolved, we expect to see a positive impact on our business. Gross profit margins are expected to rise and decline with sales volume levels from quarter to quarter.

On a continuing operations basis, ADC currently expects its fiscal 2007 sales to be in the range of $1.260-$1.290 billion. Based on this annual sales estimate and subject to sales mix and other factors, GAAP diluted EPS from continuing operations in fiscal 2007 is estimated to be in the range of $0.53 to $0.63, which includes estimated charges listed in the below table.

[TABLE OMITTED]

1 Excludes potential future restructuring, impairment and acquisition-related charges, and certain non-operating gains/losses, as well as benefits from any reduction of the deferred tax asset valuation reserve, of which the amounts are uncertain at this time. The calculation of GAAP diluted EPS from continuing operations includes the if-converted method, which assumes that ADC's convertible notes are converted to common stock, if such treatment is dilutive.

We are currently executing a four-part strategy to grow long-term value.

* Focus on targeted growth segments and geographies. Our carrier and enterprise customers need network infrastructure solutions for wireless, broadband, video, data and voice services. Our original equipment manufacturer customers also look to us for related solutions. Specifically, we are targeting FTTX, wireless capacity and coverage, metro Ethernet, and enterprise network upgrades. ADC believes it is differentiating itself from the competition with strong customer service, quality, delivery and long-term relationships.

* Achieve product/service growth. We are innovating products and services to achieve organic growth in next-generation networks, gaining market share in certain existing markets, and planning to acquire for global scale and presence.

* Improve production and delivery efficiencies. We are aggressively executing the competitive cost transformation of ADC. To increase our profit margins, we are streamlining our product portfolio by reducing the number of part numbers and designing products for modularity. We are also moving more of our manufacturing from the United States, Germany and Australia to low-cost facilities in China, the Czech Republic and Mexico.

* Optimize operating expense. We are working to optimize our operating expenses by utilizing shared services to centralize functions, simplifying our business structure and consolidating facilities to increase operating efficiencies.

Income Tax Expense

As of October 31, 2006, ADC had a total of $1,017 million in deferred tax assets (primarily for U.S. income taxes) that have been offset by a valuation allowance of $972 million. Approximately $222 million of these deferred tax assets relate to capital loss carryovers that can be utilized only against realized capital gains through October 31, 2009. Excluding the deferred tax assets related to capital loss carryovers, most of the remaining deferred tax assets are not expected to expire until after fiscal 2021. During the quarter ended October 31, 2006, the valuation allowance was reduced by $49 million attributable to deferred tax assets, which are expected to be utilized over the subsequent two-year period. As it generates pre-tax income in future periods, ADC currently expects to record reduced income tax expense until either its deferred tax assets are fully utilized to offset future income tax liabilities or the value of its deferred tax assets are fully restored on the balance sheet.
