             Ameron Reports Strong Third-Quarter Results


    PASADENA, Calif.--(BUSINESS WIRE)--Sept. 26, 2005--Ameron
International Corporation (NYSE:AMN) earned $1.58 per diluted share on
sales of $193.0 million in the third quarter ended August 28, 2005. In
the third quarter of 2004, Ameron reported a loss of $1.05 per diluted
share on sales of $155.4 million. Prior year's results included the
costs of terminating two executive benefit plans. Excluding the plan
termination costs, Ameron would have earned $.72 per share in the
third quarter of 2004.
    For the first nine months of 2005, Ameron earned $2.26 per diluted
share on sales of $508.1 million, compared to a loss of $.56 per share
on sales of $435.6 million in the first nine months of 2004. Excluding
the plan termination costs, Ameron would have earned $1.22 per share
in the first three quarters of 2004.
    "Ameron's operating segments continued to perform very well in the
third quarter," commented James S. Marlen, Ameron's Chairman,
President and Chief Executive Officer. "The Water Transmission Group
had an outstanding quarter, and both the Infrastructure Products and
Fiberglass-Composite Pipe Groups operated at record levels.
Year-to-date 2005 sales and earnings also exceeded the normalized
results of the first nine months in 2004 because of the strength of
operations, in spite of higher legal costs and expenses in the second
quarter of 2005."
    The Water Transmission Group's profits more than tripled in the
third quarter as sales were over 50% greater than in the third quarter
of 2004. The Water Transmission Group continued to benefit from the
relatively strong order backlog associated with two large projects in
California. While demand for Ameron's traditional water and wastewater
piping remains muted due to fiscal constraints and a cyclical downturn
in water infrastructure spending in Ameron's markets, interest in
Ameron's steel fabrication capabilities for the production of towers
for wind-powered electrical generation has increased. The long-term
forecast remains positive, given the need for water and energy
infrastructure; and the short-term outlook remains positive due to the
strong backlog.
    The Fiberglass-Composite Pipe Group's profits rose in the third
quarter on higher sales. Sales continued to increase due to demand for
onshore oilfield piping and for marine piping supplied by Asian
operations, while sales by European operations into Europe and the
Middle East were lower due to weaker demand and competitive pressures.
The backlog for oilfield and marine tubing remains at record levels.
Ameron's new Malaysian plant is scheduled to begin operations in the
first quarter of 2006. The forecast for the Fiberglass-Composite Pipe
Group is positive based on the strength of the oil and marine
industries.
    Compared to prior year, the Performance Coatings & Finishes
Group's third-quarter profits increased on higher sales. Sales of
heavy-duty industrial coatings in the U.S. increased in the third
quarter of 2005, compared to the same period in 2004. Corresponding
sales of lighter-duty product finishes in Australia and New Zealand
also increased. Profits rose $1.7 million on higher sales and included
a $1.4 million gain from the sale of excess land. Demand for
industrial and marine coatings in the U.S. continues to show signs of
improvement. Additionally, the Performance Coatings & Finishes Group
is expected to participate in the rebuilding of chemical, oil and
industrial infrastructure throughout the U.S. Gulf Coast.
    The Infrastructure Products Group's sales and profits improved in
the third quarter of 2005, as both Pole and Hawaiian operations had
increased profits due to higher sales. Sales of steel and concrete
poles rose due to the continued strength of housing construction
throughout the U.S. Additionally, Ameron benefited from a major
pole-replacement program sponsored by a utility in Southern
California. Hawaiian quarry and ready-mix operations benefited from
strong construction levels in Hawaii. The forecast for the
Infrastructure Products Group remains favorable due to the level of
construction throughout the U.S.
    TAMCO, Ameron's 50%-owned steel mini-mill in Southern California,
had higher sales but lower profits in the third quarter of 2005,
compared to the third quarter of 2004. Higher sales volumes were more
than offset by lower pricing and increased conversion costs. Steel
pricing remains firm but lower than at the same time last year. TAMCO
continues to forecast a strong performance for 2005.
    James Marlen continued, "Ameron's businesses have performed well
throughout 2005. Unfortunately, several of our employees and their
families in the New Orleans area were dislocated by Hurricane Katrina;
but Ameron's operations were only minimally affected. We continue to
forecast that Ameron will achieve a solid performance in 2005."
    Management measures the Company's financial performance based on
operating results without the impact of non-routine items, and
believes that non-GAAP earnings per share, excluding the non-routine
items described above, provides a more meaningful comparison of
year-over-year operating results. Non-GAAP earnings and earnings per
share are calculated as follows:
