TELLABS COMMENTS ON FIRST QUARTER EXPECTATIONS

Lisle, Ill. -- Tellabs announced today that, based on current estimates, it expects first quarter net earnings to be lower than analysts' estimates. The company expects to report revenue of approximately $630 million for the quarter ended March 31, 2000, somewhat above planned levels and up approximately 35 percent from the same period last year. The company expects diluted earnings per share for the quarter to be in the range of 27 cents to 29 cents. Excluding one time gains and charges, diluted earnings per share are expected to be in the range of 25 cents to 27 cents, compared to consensus EPS estimates of approximately 30 cents per share and 24 cents in the year-ago quarter (when restated to reflect the recent SALIX Technologies acquisition). Management remains comfortable with current full-year consensus EPS estimates.

Lower gross profit margins were the major contributor to the earnings shortfall. These lower margins were caused by several factors, including:

• Higher-than-anticipated costs associated with some components used in the company's products, which adversely affected profitability and manufacturing efficiencies.
• An unusually high number of TITAN® 5500 new systems and increased customer service installations.
• Higher-than-anticipated CABLESPAN® revenues.

The company has worked with its suppliers to obtain sufficient components, albeit at higher cost, to continue to satisfy growing customer demand. The company believes that sales of new TITAN 5500 systems, which increased dramatically in the quarter, are indicative of robust customer demand for this product and can be considered a forward indicator of continued upgrade sales in the future.

"In the first quarter, we satisfied very strong customer demand in the face of some not insignificant component issues," said Tellabs Chairman and CEO Michael J. Birck. "That, combined with the accelerated R&D and SG&A expenses we forecasted in January in support of major new products and some shifts in product mix, strained profitability during the quarter. As we look to the rest of 2000, we remain confident in our ability to reach our objectives for the year."

Tellabs expects to announce first quarter results on April 18, 2000, before the open of the Nasdaq Stock Market.
