FOR IMMEDIATE RELEASE
October 14, 2003

A. O. Smith announces third quarter earnings of $.20 per share

     Milwaukee, Wis.--A. O. Smith Corporation (AOS-NYSE) today announced third
quarter net earnings of $6.0 million or $.20 per share, in line with the
estimate announced in September but lower than third quarter 2002 net earnings
of $10.0 million or $.34 per share.

     Sales for the quarter ended Sept. 30 were $356.4 million, $4 million higher
than sales for the same period last year.

     For the first nine months of 2003, net earnings for the Milwaukee-based
manufacturer of electric motors and water heaters were $39.6 million, compared
with $40.1 million earned during the same period of 2002. Revenues for the
nine-month period were $1.16 billion compared with 2002 nine-month revenues of
$1.11 billion.

     As indicated in its Sept. 24 press release, the company incurred costs in
the third quarter due to timing delays and disruptions, as both of its
businesses undertook significant transitions. These transitions included the
transfer of electric motor production to lower-cost facilities in Mexico and
China, as well as the introduction of flammable vapor resistant water heaters.

     According to Robert J. O'Toole, chairman and chief executive officer,
"While we are disappointed in our financial performance in the third quarter, we
are pleased in achieving major milestones in both businesses. We expect to begin
receiving the benefits of these efforts in the fourth quarter and to be fully on
track with our long-term strategic direction by year-end."

     The company also announced that it has entered into a letter of intent to
acquire the assets of Taicang Special Motor Co., Ltd., near Shanghai. Taicang
will serve to expand the company's China manufacturing capability to include
hermetic motors. The transaction is expected to be completed in the fourth
quarter.

Electrical Products

     Third quarter sales of $201.2 million were modestly higher than
third-quarter 2002 sales of $197.5 million. Operating earnings of $9.6 million
were $700,000 lower than the same period in 2002, due to expenses in relocating
production to lower-cost facilities, which adversely impacted manufacturing
costs and finished goods inventories.

Water Systems

     Water Systems' sales of $155.2 million were flat compared with the third
quarter of 2002. Higher sales in China, coupled with price increases related to
steel costs and newly launched products, were offset by lower unit sales of
residential and commercial water heaters. Operating profit of $7.9 million was
approximately $5.5 million lower than the third quarter of 2002 as a result of
one-time manufacturing and freight costs due to the flammable vapor resistant
product launch.

Outlook

     "As we indicated in our Sept. 24 press release, we expect earnings for 2003
to range between $1.75 and $1.80 per share. This reduction from our previous
forecast was due to the disruptions in the third quarter and efforts to reduce
electric motor inventory in the fourth quarter," O'Toole commented. "We expect
these implementation difficulties to be behind us as we enter 2004. Accordingly,
we expect earnings per share to be in line with our strategic plan, in a range
of $2.40 to $2.60 per share." A. O. Smith Corporation will broadcast a live
conference call beginning at 9:30 a.m. (Eastern Time) today. The call can be
