Ameron Reports First-Quarter Improvement

    PASADENA, Calif.--(BUSINESS WIRE)--March 23, 2005--Ameron
International Corporation (NYSE:AMN) today reported earnings of $.06
per diluted share on sales of $138.8 million for the first quarter
ended February 27, 2005. Ameron lost $.34 per diluted share on sales
of $129.7 million in the quarter ended February 29, 2004.
    Significant profit improvements by the Water Transmission and
Infrastructure Products Groups were partially offset by lower profits
from the Fiberglass-Composite Pipe Group and a larger loss from the
Performance Coatings & Finishes Group. Income from TAMCO, Ameron's
50%-owned steel mill in California, was slightly higher in the first
quarter of 2005.
    "The first quarter of 2005 was substantially improved over last
year when labor disputes disrupted operations," commented James S.
Marlen, Ameron's Chairman, President and Chief Executive Officer.
"Both the Water Transmission and Infrastructure Products Groups
started the year strongly in spite of record wet weather in Southern
California. The Fiberglass-Composite Pipe Group also continued to
perform well in the first quarter."
    Although wet weather slowed operations, the Water Transmission
Group returned to a traditional level of sales and profits in the
first quarter of 2005. The Group had a slight loss on lower sales in
the first quarter of 2004 due to strikes at two plants in Southern
California. The Water Transmission Group entered 2005 with a
relatively large backlog, and the forecast remains positive due to the
backlog of orders.
    The Fiberglass-Composite Pipe Group's sales and segment income
declined in the first quarter of 2005 due to the timing of projects
and mixed market conditions. Sales of piping for industrial and
fuel-handling applications, supplied by Ameron's operations in the
U.S. and Europe, were lower. Partially offsetting the decline were
higher sales of onshore oilfield piping and marine piping supplied by
Asian operations. Profits declined due to lower sales. The backlog is
robust, and the forecast for the Fiberglass-Composite Pipe Group
remains positive, driven by high oil prices, the strength of marine
and offshore markets and the high cost of competitive steel tubing.
    The Performance Coatings & Finishes Group had a larger loss in the
first quarter of 2005 than in the first quarter of 2004, on lower
sales. Sales of industrial and marine coatings into U.S. and European
markets declined due to continued sluggish demand. Additionally, the
increasing strength of the euro and the British pound impacted the
competitiveness of Ameron's operations in the Netherlands and the
U.K., reducing sales into dollar-based markets in the Middle East,
North Africa and Eastern Europe. Sales in the U.S. were down due in
part to the loss of a contract to supply coatings to the U.S. Navy.
Losses increased due to lower sales, higher raw material costs and
plant inefficiencies. The outlook for this business is uncertain as
chemical and industrial markets served by the Group have not shown
signs of recovery.
    The Infrastructure Products Group had significantly higher sales
and profits in the first quarter of 2005, compared to the same period
in 2004. The improvement came from Hawaiian operations, which were
disrupted by a strike in the first quarter of 2004. Sales of poles
declined in the first quarter as the wet weather in Southern
California affected construction projects and pole installations. The
forecast for the Infrastructure Products Group remains positive due to
the favorable level of residential, commercial and government
construction.
    TAMCO's first-quarter profits were similar in 2005 and 2004.
Shipments of construction rebar slowed in the fourth quarter of 2004
and the first quarter of 2005 as customers adjusted inventory levels
and imports increased. In spite of wet weather which reduced
construction in the first quarter, shipments began to increase in
January as customers' inventory levels returned to traditional levels.
TAMCO is forecasting a strong performance for the remainder of 2005,
based on expected demand and current steel prices.
    James Marlen continued, "The first quarter is seasonally Ameron's
slowest quarter. We are pleased with the performance of most of our
operations and are taking steps to improve those that are
underperforming. Overall, we continue to forecast a solid improvement
in 2005."
