                    ADC UPDATES GUIDANCE ON FINANCIAL RESULTS

MINNEAPOLIS -- JANUARY 19, 2001 -- ADC (Nasdaq: ADCT, WWW.ADC.COM), a leading
global supplier of fiber optics, network equipment, software and integration
services for broadband, multiservice networks, today announced that despite
strong sales growth it expects to report results below its previous guidance for
the first fiscal quarter ending January 31, 2001. ADC is also revising its
guidance for fiscal year 2001.

As a result of the current challenging economic environment and
lower-than-expected domestic spending by communications service providers in
2001, ADC now expects sales in the first quarter of 2001 to be approximately
$800 million (compared to $594 million in the first quarter of 2000) and pro
forma diluted earnings per share to be $0.05 to $0.07 (compared to $0.07 in the
first quarter of 2000). ADC expects lower operating profit margins in the
quarter as a result of changes in the mix of products sold and not yet
benefiting from the full effect of recent cost reduction actions. International
sales growth in the first quarter of 2001 is expected to remain strong with
growth exceeding that in the U.S. International sales are expected to reach
25-30% as a portion of total ADC sales compared to 22% in the first quarter of
2000.

"At this time, ADC sees a significant change in economic and market conditions
compared to the assumptions in our November 2000 guidance. Given these current
conditions, we believe it is appropriate to be more cautious regarding our
growth assumptions," said William J. Cadogan, chairman and chief executive
officer of ADC. "Consequently, we are revising our annual growth assumptions for
sales and pro forma diluted earnings per share to approximately 15% from
previous guidance of 25-30%. Until economic and market conditions improve, we
expect this revised year-over-year growth rate of sales and earnings per share
for both fiscal year 2001 and the remaining quarters of 2001. We remain
confident that our strategy to provide broadband products and services for the
`last mile/kilometer' of communications networks is focused on one of the most
rapidly expanding areas of the communications industry."

During the quarter, ADC began implementing plans to control expense growth in
2001. As a result of cost reduction actions to rationalize product lines and
reduce the number of employees in 2001, ADC expects to record non-recurring
charges in the first and second quarters in amounts that have not yet been
determined.

Sales by business group as a percent of total sales are expected to remain at
approximately 50-55% for Broadband Connectivity, 25-30% for Broadband Access and
Transport, and 15-20% for Integrated Solutions for the first quarter and the
fiscal year of 2001.
