Cummins Increases Earnings Guidance.

Business Editors

COLUMBUS, Ind.--(BUSINESS WIRE)--April 6, 2004

Cummins Inc. (NYSE:CMI) today announced that it expects to earn more than its original guidance for the first quarter and all of 2004 on the basis of strong engine volumes and a broad recovery in many of the Company's key markets, which more than offset the impact of rising commodity prices.

For the first quarter, the Company expects its earnings to be in the range of $0.65 to $0.75 cents a share versus the prior guidance of $0.40 to $0.50 cents a share. Earnings in the second quarter are expected to be in the range of $1.00 to $1.10 a share. The Company did not previously provide second-quarter guidance.

For the full year 2004, Cummins is increasing its earnings guidance to $4.00 to $4.20 a share, compared to the prior forecast of $3.20 to $3.40 a share.

"With growing demand across all of our markets and our improved cost structure, Cummins is well positioned to deliver strong financial performance in 2004 and beyond," said Tim Solso, Cummins Chairman and Chief Executive Officer.

Solso is expected to tell shareholders at the Company's Annual Shareholders' Meeting today that revenues will grow by approximately 15 percent this year over 2003 because of increased demand across all engine segments, particularly the North American heavy-duty truck market, improved performance in Cummins Power Generation Business and continued strength in key international markets, such as China and India. While revenues are growing, the effect of rapid increases in commodity prices remains uncertain, notably the impact of steel pricing on the Filtration Business.

Cummins will discuss its first-quarter results in a teleconference at 9 a.m. (EST) and 10 a.m. (New York time) on April 22, 2004. The teleconference will be available through the Company's webcast on www.cummins.com.
