A. O. Smith reduces forecast for 2005

Milwaukee, Wis.--A. O. Smith Corporation (AOS-NYSE) today lowered its forecast for 2005 to a range of between $1.25 and $1.45 per share, from the previously communicated forecast of $1.45 to $1.65 per share. The company expects earnings for the second quarter to range between $.15 and $.20 a share. As previously announced the company will record an estimated $.35 annual charge for restructuring which includes approximately $.30 in the second quarter. Excluding the restructuring charge, the company expects to earn between $1.60 and $1.80 per share for the year and $.45 to $.50 per share for the quarter.

After reviewing water heater industry shipment data for April and May, which declined fourteen percent in residential and twenty five percent in commercial compared with 2004, the company is reducing its projection for industry shipments for the year. The company believes this lower commercial and residential market projection is primarily caused by higher than expected wholesale inventories. As a result the company has reduced its projection for full year sales and earnings at its Water Systems business. Expectations for the Electrical Products business are essentially unchanged from the company's outlook at the time of its earnings forecast in April.

A.O. Smith will issue its second quarter earnings results on July 15, 2005 and will broadcast a live conference call at 10:00 a.m. (Eastern Time). The call can be heard on the company's web site, www.aosmith.com. An audio replay of the call will be available on the company's web site after the live event.
