Business Editors & Technology Writers

First $1 Billion-Plus Sales Quarter, Up Approximately 60%;

EPS to Meet or Exceed Consensus Estimates in the Quarter;

Confirms Strong Outlook for 2001

MINNEAPOLIS--(BUSINESS WIRE)--Nov. 2, 2000

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 it expects sales to exceed $1 billion in the fourth quarter ended October 31, 2000, an increase of approximately 60% over sales of $634 million in the comparable quarter of 1999. All amounts are estimated as of November 1, 2000. The 1999 sales are restated to account for ADC's three pooling-of-interests acquisitions completed during fiscal year 2000.

ADC expects to meet or exceed the diluted earnings per share consensus estimates, before non-recurring credits and charges, of $0.17 per share in the fourth quarter of 2000 and $0.46 per share for fiscal year 2000. ADC also confirmed its expectation to achieve the diluted earnings per share consensus estimates, before non-recurring credits and charges, in the range of $0.68 to $0.70 per share for fiscal year 2001. The source of the consensus estimates is First Call(R).

"We are pleased to reach another significant milestone in ADC's financial performance - surpassing one billion dollars in sales for the first time in a quarter, " said William J. Cadogan, chairman and chief executive officer of ADC. "Despite recent market concerns, we remain confident that we can achieve our long-term goals for annual sales growth at 25% to 30% with earnings per share growth at the same or higher rate, before non-recurring credits and charges. ADC's strong operating results to date and continued strong growth expectations are a result of our leading market positions, diversified product mix and broad global customer base, supported by our outstanding employees, significant capacity expansions worldwide, critical-mass acquisitions and innovative new product platforms."

ADC expects to report its actual financial results for the fiscal fourth quarter of 2000, and discuss its outlook for the fiscal year 2001, on November 28, 2000, after the market close, with a conference call scheduled for the same day at 5 p.m. Eastern time.
