ADC Updates Financial Outlook for Fiscal Year 2008.

MINNEAPOLIS -- ADC (NASDAQ: ADCT)(www.adc.com) today announced an update to its financial outlook for its fiscal year 2008 ending October 31, 2008. These updated estimates are subject to the completion of ADC's actual financial results for the fiscal 2008 third quarter and year. ADC is scheduled to announce financial results on September 4, 2008 for its third quarter ending August 1, 2008.

At this time, ADC currently expects sales from continuing operations for fiscal 2008 to be in the range of $1.500-$1.520 billion. Previous annual guidance provided on June 4, 2008 was that ADC's fiscal 2008 sales would be in the range of $1.520-$1.540 billion. ADC now expects to have year-over-year sales growth for fiscal year 2008 of 13%-15%.

Compared to previous fiscal 2008 sales guidance, the updated financial outlook primarily reflects lower sales of copper and fiber connectivity products in the United States resulting mainly from customers' recent budget reviews and ordering patterns, as well as the resulting effects on original equipment manufacturers' demand for ADC products.

"We remain firmly committed to managing our business strategically for the long term, but the inherent short-lead time nature of our business sometimes results in quarter-to-quarter market-related movements, up or down, in our sales expectations," said Robert E. Switz, president and CEO of ADC. "Current industry conditions are driving a change in our financial outlook for this fiscal year, but we see no change in our customers' long-term commitment to investing in the network infrastructure required to deliver broadband services to business, residential and mobile subscribers. ADC is well positioned to continue supplying products and services to these customers' strategic builds in the high-growth segments of fiber-based and wireless communications networks."

ADC currently expects its third quarter 2008 sales will be 3-5% lower than the second quarter of 2008 and expects its fourth quarter 2008 sales to be around the third-quarter level. Due to the change in sales volume and product mix, ADC's gross margins in 2008 are now expected to be around 34% for the second half and around 35% for the full year compared to previous guidance of 36% for the full year.

Based on these current annual sales and gross margin estimates, subject to sales mix, other factors and an assumed effective income tax rate of around 10%, ADC now estimates that GAAP diluted EPS from continuing operations in 2008 will be in the range of $0.18 to $0.26 which includes estimated charges (benefits), net of tax, listed in the below table. ADC's previous annual guidance provided on June 4, 2008 for 2008 GAAP diluted EPS from continuing operations was in the range of $0.31 to $0.39.

(1) Excludes potential future restructuring or impairment charges, any incremental purchased intangible amortization, and certain non-operating gains/losses, as well as further adjustments 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.
