             Ameron Reports Record Second-Quarter Results

    PASADENA, Calif.--(BUSINESS WIRE)--June 22, 2006--Ameron
International Corporation (NYSE:AMN) today reported earnings of $2.11
per diluted share on sales of $193.7 million for the quarter ended
June 4, 2006, which compares to earnings of $.62 per diluted share and
sales of $176.2 million for the second quarter ended May 29, 2005. For
the six months ended June 4, 2006, earnings per diluted share totaled
$2.53 on sales of $369.0 million, compared to earnings of $.68 per
diluted share and sales of $315.0 million for the six months ended May
29, 2005.
    The significant improvement in results was primarily attributable
to stronger year-over-year performances in all business segments, with
the exception of the Water Transmission Group, which, as expected, is
experiencing a temporary lull in major projects in its primary water
piping market in the western U.S. TAMCO, Ameron's 50%-owned steel
mini-mill, also achieved higher income due to steady market conditions
and favorable margins.
    The results for the second quarter of 2006 included a pretax gain
of $9.0 million on the sale of excess property in Brea, California,
which had been used as a research and development laboratory and a
regional warehouse for the Performance Coatings & Finishes Group. The
site was vacated as part of a continuing restructuring program to
reduce costs and improve operating efficiencies within the Group. The
second quarter of 2005 was adversely impacted by unusual legal fees
and expenses of $6.1 million before taxes.
    "The second-quarter and first-half results were outstanding with
or without the property gain. The business conditions in the
Fiberglass-Composite Pipe Group, Infrastructure Products Group,
Performance Coatings & Finishes Group and TAMCO remain favorable. This
bodes well for the second half of 2006," said James Marlen, Ameron's
Chairman, President and Chief Executive Officer.
    The Fiberglass-Composite Pipe Group had significantly higher sales
(up 43%) in the second quarter of 2006, compared to the same period of
2005, while segment income increased (up 69%) in line with the sales
growth. The sales increase was broad-based across most markets served
worldwide. The demand for onshore oilfield piping continued at a high
level, chemical and industrial demand remained steady, and
fuel-handling piping sales in the U.S. improved. The marine and
offshore markets, served primarily from Ameron's operations in
Singapore and Malaysia, remain strong, due to the continued high level
of marine construction worldwide. The outlook for the
Fiberglass-Composite Pipe Group remains positive. The business should
continue to operate at record levels, based on the current order
backlog and generally favorable market conditions throughout the
world.
    The Performance Coatings & Finishes Group had higher sales and
segment income in the second quarter of 2006, compared to the second
quarter of 2005. The improved performance was attributable to the
steady recovery of key markets served in the U.S., primarily the
marine and offshore markets and the protective coatings markets for
chemical and industrial maintenance applications. Sales increased 13%,
based primarily on the improvements in the U.S. In local currencies,
all foreign operations achieved slightly higher sales. The improvement
in segment income was attributable primarily to higher sales and
higher selling prices. The outlook for the Performance Coatings &
Finishes Group should continue to improve as long as the current
market recovery is sustained.
    The Water Transmission Group had lower sales and segment income in
the second quarter of 2006, compared to the same period of 2005. The
soft market conditions in water piping projects in the western U.S.
had been anticipated. To counterbalance the cyclical lull of major
pipe projects, the Group has entered the wind-energy market by
fabricating large-diameter towers for wind-turbine manufacturers. This
rapidly growing market in the western U.S. provides an excellent
growth and diversification opportunity for the Water Transmission
Group. The outlook for the business is for the soft pipe market
conditions to continue beyond 2006. Longer term, the outlook is
positive, based on the projected timing of pipe projects and the need
to expand and upgrade the water infrastructure system in the western
U.S.
    The Infrastructure Products Group had higher sales (up 12%) and
segment income in the second quarter of 2006, compared to the same
period in 2005. Both Ameron's Hawaiian operation and the Pole Products
operation had improved results. The Hawaiian operation continued to
benefit from solid construction market conditions, primarily
residential construction, on Oahu and Maui. The residential
construction market drivers include increased demand for housing
subdivisions, high-rise condominiums and timeshare resorts. Pole
Products continued to achieve market penetration gains in the
southeastern U.S., while sales in the western U.S., primarily
California, remained strong due to residential demand for decorative
concrete lighting poles. The concrete pole plant in Anniston, Alabama,
which serves the southeastern U.S., is operating at capacity, and
expansion plans are being evaluated in order to continue to serve this
growing region. The increase in segment income was attributable to the
higher sales and improved margins boosted by higher selling prices.
The outlook for the Infrastructure Products Group is positive as a
result of continuing strong construction market conditions.
    TAMCO had higher net income in the second quarter of 2006,
compared to the same period of 2005. Demand for steel rebar continues
high in the western states served by TAMCO. The outlook for TAMCO
remains favorable.
    James Marlen continued, "The record earnings performance is a good
indicator that our businesses are operating efficiently and
capitalizing on growth opportunities and generally favorable market
conditions. The businesses are well positioned to have a solid second
half."
