Ameron’s Independent Directors Conclude Review; Outcome Rebuts Baseless Allegations by Barington

PASADENA, Calif.—February 24, 2011—Ameron International Corporation (NYSE:AMN) today announced that the independent members of its Board of Directors (the “Independent Directors”) have completed an internal inquiry into the veracity of certain allegations made by Barington Capital Group, L.P., an activist investment firm based in New York. After a thorough inquiry, the Company’s Independent Directors concluded that Barington’s allegations were baseless and unfounded. The Independent Directors initiated the inquiry shortly after receiving a letter on January 5, 2011 from Barington.

Based on, among other things, review of the Company’s books and records, review of the Company’s past disclosure, interviews with certain of the Company’s employees and third parties and the report of outside counsel, the Independent Directors concluded that contrary to Barington’s allegations: (1) James Marlen, the Company’s Chief Executive Officer, has not committed any wrongdoing; (2) the Company’s prior disclosures relating to perquisites for Mr. Marlen were accurate in all but insignificant respects, (3) the disclosure practices for Mr. Marlen were consistent with those of the Company’s other named executive officers; and (4) the Company’s prior related party transaction disclosures complied in good faith with the rules and regulations of the Securities and Exchange Commission.

Focusing on specific Barington allegations, the Independent Directors found that the Company’s succession planning process is firmly on track, the atmosphere among employees is positive, the Company did not pay for any of Mr. Marlen’s residences, including his apartment in Pasadena, or for his expenses if he was vacationing, and that the Board held only one meeting outside of California, and that was a meeting which was fully disclosed in the Company’s 2006 proxy statement.

Regarding the employment of Mr. Marlen’s sons, the Independent Directors also found that James and John Marlen were hired by the Company in a manner consistent with the Company’s policies and procedures, and Andrew Marlen was hired by TAMCO, an uncontrolled unconsolidated affiliate, without Mr. Marlen’s involvement in the hiring process.

The Independent Directors’ Recommendations

The Independent Directors recommended that the Company make additional disclosure with respect to the employment of Mr. Marlen’s sons in its preliminary proxy statement, filed February 9, 2011, beyond what the

Company believes is required by the Securities and Exchange Commission rules. Additionally, the Independent Directors adopted a new related party policy in addition to the Company’s existing conflict of interest policy.

to our SHAREHOLDERS

Ameron’s excellent track record of consistently generating quality earnings and adhering to a responsible dividend policy has created value for our shareholders. Over the past five years, cumulative shareholder returns totaled 78% with an annualized compounded shareholder return of 12%, compared to an average annual return of 3% by relevant peer companies and leading market indices, such as the Dow Jones Index, the S&P 500 Index, the Russell 2000 Index and the broad NYSE Index.

Our primary objectives are to be effective stewards of the Company’s capital resources, execute a sound business strategy to profitably grow the Company and generate favorable returns for shareholders. For nearly twenty years, the Company has been successful with this focused approach.

In 2010, Ameron continued to be confronted with challenging market conditions caused by the global economic recession. Most of Ameron’s key market segments, such as the water and wastewater sector, wind energy, residential and commercial construction, and the infrastructure market, have not recovered. The markets, particularly in the regions in which Ameron competes, are especially exposed to the impact of state and local government budget deficits, financing difficulties, high unemployment and the collapse of the U.S. housing market. Despite these difficult conditions, Ameron had a solid financial performance in 2010. Earnings totaled $5.00 per share on sales of $503 million in 2010, compared to $3.61 per share on sales of $547 million in 2009. Earnings in 2010 included a pretax gain of approximately $48 million on the sale of TAMCO, the Company’s 50%-owned steel mini-mill. The results for 2010 also included $5.8 million of tax expenses primarily associated with the write-off of expiring tax loss carry forwards and the repatriation of approximately $44 million of cash from foreign operations, the write-down of a property of a discontinued business of $1 million pretax, and an unexpected, unfavorable French appeals court judgment of $.9 million pretax. Normalized earnings for the Company, excluding these items, was in the range of earnings guidance originally provided at the start of the year. In addition to the solid earnings performance, the Company generated positive cash flow from operations of over $52 million, and the Company’s cash position increased by $56 million, even after a special dividend of $3.00 per share, or approximately $28 million, was paid to shareholders.

OPERATIONS REVIEW

While the Fiberglass-Composite Pipe Group’s sales grew 8% in 2010, compared to 2009, sales of the Company’s construction-related businesses declined. The infrastructure markets, including residential and commercial construction and the water and wind energy sectors, were weak due to the economic conditions which impacted Ameron’s primary operations in California, Arizona, Nevada and Hawaii. The energy-related markets were strong, especially the onshore oilfield markets worldwide, which benefitted the Fiberglass-Composite Pipe Group.

The Fiberglass-Composite Pipe Group experienced stronger demand for oilfield piping in South America, Canada and the U.S., while marine and offshore energy exploration and production markets softened, with demand replaced by lower-margin industrial sales, primarily, for projects in the Middle East. While the marine and offshore market softened somewhat, compared to 2009, when two of the largest FPSO’s (Floating Production Storage and Offloading vessels) ever constructed were completed, the market continued as the major driver of the business and the most significant contributor to the profitability of the Group. Operations in Brazil improved due to higher demand for municipal water piping systems and higher onshore oilfield demand due, in part, to full commercialization of the Company’s new oilfield piping plant. The new plant will serve the South America market and supplement worldwide capacity requirements. Operations in the U.S. achieved higher sales due to the introduction of a new product line to serve the national water and wastewater market, penetration of the mining market and stronger demand for oilfield products in Canada.

Looking ahead, we expect continued growth of the Fiberglass-Composite Pipe Group. The energy-related markets, including onshore oilfield, should be strong; demand for marine and offshore vessels should improve; we expect to make progress in penetrating the South America industrial marine and offshore markets; and new growth opportunities in areas such as coal-bed methane and shale gas exploration should develop.

The Water Transmission Group continued to be adversely impacted by the lack of water infrastructure investments in the western U.S. region and the slowdown of wind energy projects throughout the U.S. While water pipe bid activity was solid in Northern California, the markets in Southern California, Arizona and Nevada remained extremely weak, with bid levels at historic lows. While it is clear that new and upgraded water infrastructure systems are needed to replace the aging infrastructure in the West and throughout the U.S., investment projects are being constrained by economic conditions, state, local and municipal budgets, financing difficulties and static population demographics. Water pipe sales in 2010 were down by 5% from the already cyclical low level of 2009. The wind tower business had sharply lower sales due to the lack of wind energy projects in the western region. Wind tower sales in 2010 were 50% lower than 2009 as the wind energy industry suffered from lack of financing, permitting issues and uncertainty regarding long-term tax and national renewable energy policies. Wind tower demand was also tempered by customers’ excess tower inventory and the importation of wind towers from Asian manufacturers. Both the water transmission pipe business and the wind tower operation serve critical U.S. industries: water and energy and, over the near term, the water pipe market and the market for wind towers are expected to continue to face cyclical issues and project financing issues that will constrain demand. However, over the long term, the water transmission pipe and wind tower businesses represent outstanding opportunities, especially given the Company’s strong market position and reputation.

The Infrastructure Products Group had lower sales and segment income in 2010 as both Ameron Hawaii and the Pole Products Division continued to face weak construction markets. The Pole Products Division serves primarily the residential construction markets in the West and the Southeast. With a strong dependence on the new housing construction market, the business experienced a 60% decline in sales of decorative concrete lighting poles since the housing peak in 2006. The U.S. housing market is still in a crisis mode and housing permits and housing starts remain at the lowest level in over 60 years, with new residential construction down 75% from the peak. The business, however, has aggressively restructured operations and reduced costs and remains profitable. The demand for decorative concrete lighting poles is not expected to experience any meaningful recovery for a number of years as new housing construction should lag an economic recovery due to the oversupply of available housing.

Ameron Hawaii experienced lower sales due to the weak demand for aggregates and concrete on both Oahu and Maui due to the decline in construction spending. While military and governmental construction spending was stable, other key markets, such as residential, commercial, time shares, high-rise condominiums and resorts, remained weak due to the Hawaiian economy. A gradual recovery of the Hawaiian economy is anticipated; however, new construction spending is expected to lag.

On balance, our businesses have performed well given the current economic environment. The management team has focused on cost containment, employment levels and aggressive working capital management since market conditions softened. In this connection, the number of employees has been reduced by 690 positions (20%) over the past three years, while working capital levels (excluding cash) have been reduced by $83 million. These efforts will continue to be a priority as we manage through the current business cycle.

There continues to be uncertainty in our markets which makes business forecasting more difficult than normal. While market conditions will continue to be somewhat soft, we expect earnings from continuing operations to improve from the normalized earnings of 2010, and we estimate earnings for 2011 will be in the range of $3.00 to $3.50 per share. The earnings improvements will be attributable primarily to the strength of the Fiberglass-Composite Pipe Group, while the other business segments’ earnings will be based on steady performance. The Company’s financial performance is dependent on economic conditions and specific market factors and earnings could be stronger as the Company is well-positioned to capitalize on opportunities that could arise in the water, wind energy and infrastructure markets.

Our business have performed well given the current economic environment.

Ameron’s excellent track record has created value for our shareholders . . .

During 2010, the Company completed the sale of its 50%-ownership of TAMCO to Gerdau Ameristeel US Inc. for $82.5 million and recognized a pretax gain of $48.4 million. The decision to divest TAMCO was based on an assessment of the long-term forecasted demand for steel rebar in the western U.S. and the shift in competitive dynamics that occurred over the past couple of years. Major steel rebar competitors had added or announced plans to add capacity and had also pursued a vertical integration strategy by acquiring steel fabrication companies. These actions resulted in TAMCO being at a competitive disadvantage to the larger, fully-integrated steel companies in the region. The divestiture was timely, strategic and was consummated on favorable terms for the Company.

The Company maintains a healthy, liquid financial position. Cash balances and short-term investments totaled $237 million at the end of 2010 and outstanding debt totaled $31 million, resulting in a net positive cash position of $206, an increase of $63 million from last year. In addition, the Company has access to unused bank lines of $111 million and has the capacity to raise additional capital. Cash redeployment remains a key priority and various alternatives are being evaluated. These options range from internal growth initiatives to acquisitions, issuing another special dividend, and expanding our announced $50 million share repurchase program, which was authorized in 2010. The share repurchases will be made from time to time in the open market at market prices, and commenced in February 2011. Adequate capital resources are available to support the strategic plan of our core businesses and to pursue reinvestment opportunities.

BUSINESS STRATEGIES

Enhancing shareholder value and generating quality, consistent earnings over time can only result from developing the proper business strategies and effectively executing on those plans. Delivering on that philosophy has been our trademark over the years. The Company’s business strategies are tailored to the competitive strengths of each business and reflect market opportunities and market trends. These strategies are also long-term in nature but remain flexible to adjust to economic conditions. Following is a summary of the key strategies of each business:

Fiberglass-Composite Pipe Group

Maintain leadership position in onshore oilfield, marine and offshore markets worldwide

Continue expansion plans in South America

Strengthen leading product and manufacturing technology positions

Expand served markets and extend application utilization

Pursue geographic expansion and establish manufacturing presence in key markets

Successfully introduce sand-core pipe technology to serve national water and wastewater markets

Capitalize on emerging market opportunities, such as, coal bed methane, shale gas, and the next generation of oil and gas exploration and production vessels

Water Transmission Group

Protect water pipe market position in key western states

Closely control costs and improve manufacturing efficiencies while managing through the down cycle

Continue new product technology programs, such as Pressure Cast Steel Pipe

Diversify customer base in the wind tower market and evaluate opportunities to expand geographic reach

Selectively follow major project opportunities in Mexico

Infrastructure Products Group — Ameron Hawaii

Maintain market position on Oahu and Maui in soft economic conditions

Aggressively control cost, product quality and service levels

Capitalize on major planned infrastructure projects, such as Honolulu Light Rail Project

Develop plans for utilization of depleted sections of Kapaa quarry

Infrastructure Products Group — Pole Products

Maintain market leading position in California and southeastern U.S. markets

Control costs and continue productivity improvement programs during housing market down cycle

Pursue an expansion strategy in steel poles for highway lighting and signal control applications

Pursue growth opportunities for decorative concrete lighting poles in commercial, governmental, and military markets

The Company pursues numerous strategic initiatives as a critical part of managing and growing the business and striving to create value for shareholders. The programs are in various stages of development, from embryonic to commercialization. Some of the programs may not be successful, while others may add significant value. Following are some examples of our current growth initiatives.

Construct Fiberglass Pipe Plant in China

This initiative represents both a growth opportunity through a geographic expansion and a cost reduction opportunity for the Fiberglass-Composite Pipe Group. The marine and offshore construction market is undergoing a significant migration of shipbuilding from South Korea to China. To efficiently address the demand shift, establishing a manufacturing presence in the coastal regions of China is being evaluated. A local presence would lower costs versus serving the market from Singapore and Malaysia, provide better service and capitalize on the growing markets in China.

Construct a Steel Pole Plant

The Company recently announced plans to construct a new steel pole plant in Tulsa, Oklahoma. The 75,000 square foot facility will cost approximately $35 million and will take nearly two years to complete. The investment is expected to significantly expand the Company’s position in the national transportation market for highway lighting and traffic signal control structures and provide an opportunity to serve growing markets, such as, light rail, high mast

and smart grid structures and highway signage. The new facility will include a proprietary manufacturing process that should make the Company’s steel pole product line cost competitive across most market segments. The target markets are large and generally benefit from governmental funding. Demand is forecasted to be steady over the long term to support the necessary expansion and upgrade of the U.S. transportation system. The plant would have an initial sales capacity of approximately $75 million. We believe this represents an excellent long-term growth opportunity.

Construct Fiberglass Pipe Plant in Middle East

The Middle East continues to be the world’s largest onshore oil producer and represents a growth opportunity for the use of fiberglass pipe. Many oilfields in the Middle East are beginning to experience higher corrosion rates due to the increased quantities of water required to maintain adequate oil extraction. The Company’s subsidiary, Centron International, Inc., a leading supplier of onshore oilfield piping worldwide, would provide solutions to the corrosion problems in the Middle East. Construction of a Middle East plant could capitalize on this long-term growth opportunity in the onshore oilfield market.

Complete Development of Pressure Cast Steel Pipe

A revolutionary pipe design technology has been developed by the Company. Through a proprietary manufacturing process, a steel pipe has been designed with superior property characteristics in terms of pipe stiffness that requires significantly thinner steel. The new pipe cost savings are expected to be dramatic, and the design will also provide for lower transportation and installation costs. The Pressure Cast Steel Pipe represents a potential breakthrough technology for the water pipe industry. Development and testing needs to be completed, and the manufacturing process finalized; however, we believe this initiative holds exceptional promise.

CONCLUSION

While certain markets continue to remain weak, we are pleased with 2010 results and look forward to an improvement in 2011. The Company will be led by the Fiberglass-Composite Pipe Group and constrained by its cyclical, construction-related businesses. We will continue to focus on controlling costs to maximize profits in spite of the softness in some areas, and we are actively reviewing all operations for improvements and opportunities. Likewise, we are investing in expanding and enhancing the Company’s capabilities and markets throughout the world. We remain optimistic that as the economy recovers, the Company will achieve superior long-term results by capitalizing on its strong existing market positions and its ability to expand into new markets.

I want to thank our dedicated and talented management team, our Board of Directors for their advice and support, and employees worldwide for their extraordinary efforts during difficult business conditions. Again, I remain very optimistic on the long term potential of each of our businesses, and I am confident we will capitalize on growth opportunities as the economic cycle turns.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Ameron International Corporation (“Ameron”, the “Company”, the “Registrant” or the “Corporation”) is a multinational manufacturer of highly-engineered products and materials for the chemical, industrial, energy, transportation and infrastructure markets. Ameron is a leading producer of water transmission lines; fiberglass-composite pipe for transporting oil, chemicals and corrosive fluids and specialized materials; and products used in infrastructure projects. The Company operates businesses in North America, South America, Europe and Asia. The Company has three reportable segments. The Fiberglass-Composite Pipe Group manufactures and markets filament-wound and molded composite fiberglass pipe, tubing, fittings and well screens. The Water Transmission Group manufactures and supplies concrete and steel pressure pipe, concrete non-pressure pipe, protective linings for pipe and fabricated steel products, such as large-diameter wind towers. The Infrastructure Products Group consists of two operating segments, which are aggregated: the Hawaii Division which manufactures and sells ready-mix concrete, sand and aggregates, concrete pipe and culverts and the Pole Products Division which manufactures and sells concrete and steel lighting and traffic poles. The markets served by the Fiberglass-Composite Pipe Group are worldwide in scope. The Water Transmission Group serves primarily the western U.S. for pipe and sells wind towers primarily west of the Mississippi River. The Infrastructure Products Group’s quarry and ready-mix business operates exclusively in Hawaii, and poles are sold throughout the U.S. Ameron also participates in various affiliate companies, directly in Saudi Arabia, and indirectly in Egypt.

During the fourth quarter of 2010, the Company sold its 50% ownership in TAMCO, a steel mini-mill operating in California. The Company reports its investment in TAMCO using the equity method of accounting.

During the third quarter of 2006, the Company sold its Performance Coatings & Finishes business (“Coatings Business”). The results from this segment are reported as discontinued operations for all the reporting periods. Accordingly, the following discussions generally reflect summary results from continuing operations unless otherwise noted. However, the net income and net income per share discussions include the impact of discontinued operations.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management’s Discussion and Analysis of Liquidity and Capital Resources and Results of Operations are based upon the Company’s consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires Management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities during the reporting periods. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.

A summary of the Company’s significant accounting policies is provided in Note (1) of the Notes to Consolidated Financial Statements, herein. In addition, Management believes the following accounting policies affect the more significant estimates used in preparing the consolidated financial statements.

The consolidated financial statements include the accounts of Ameron and all wholly-owned subsidiaries. All material intercompany accounts and transactions are eliminated. The functional currencies for the Company’s foreign operations are the applicable local currencies. The translation from the applicable foreign currencies to U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using a weighted-average exchange rate during the period. The resulting translation adjustments are recorded in accumulated other comprehensive income/(loss). The Company advances funds to certain foreign subsidiaries that are not expected to be repaid in the foreseeable future. Translation adjustments arising from these advances are also included in accumulated other comprehensive income/(loss). The timing of repayments of intercompany advances could materially impact the Company’s consolidated financial statements. Additionally, earnings of foreign subsidiaries are often permanently reinvested outside the U.S. Unforeseen repatriation of such earnings could result in significant unrecognized U.S. tax liability. Gains or losses resulting from foreign currency transactions are included in other income, net.

Revenue for the Fiberglass-Composite Pipe and Infrastructure Products segments is recognized when risk of ownership and title pass, primarily at the time goods are shipped, provided that an agreement exists between the customer and the Company, the price is fixed or determinable and collection is reasonably assured. Revenue is recognized for the Water Transmission Group primarily under the percentage-of-completion method, typically based on completed units of production, since products are manufactured under enforceable and binding construction contracts, typically are designed for specific applications, are not interchangeable between projects, and are not manufactured for stock. Revenue for the period is determined by multiplying total estimated contract revenue by the percentage of completion of the contract and then subtracting the amount of previously recognized revenue. Cost of earned revenue is computed by multiplying estimated contract completion cost by the percentage of completion of the contract and then subtracting the amount of previously recognized cost. In some cases, if products are manufactured for stock or are not related to specific construction contracts, revenue is recognized under the same criteria used by the other two segments. Revenue under the percentage-of-completion method is subject to a greater level of estimation, which affects the timing of revenue recognition, costs and profits. Estimates are reviewed on a consistent basis and are adjusted periodically to reflect current expectations. Costs attributable to unpriced change orders are treated as costs of contract performance in the period, and contract revenue is recognized if recovery is probable. Disputed or unapproved change orders are treated as claims. Recognition of amounts of additional contract revenue relating to claims occurs when amounts have been received or awarded with recognition based on the percentage-of-completion methodology.

The Company expenses environmental clean-up costs related to existing conditions resulting from past or current operations on a site-by-site basis. Liabilities and costs associated with these matters, as well as other pending litigation and asserted claims arising in the ordinary course of business, require estimates of future costs and judgments based on the knowledge and experience of Management and its legal counsel. When the Company’s exposures can be reasonably estimated and are probable, liabilities and expenses are recorded. The ultimate resolution of any such exposure to the Company may differ from expectations due to subsequent developments.

Inventories are stated at the lower of cost or market with cost determined principally on the first-in, first-out (“FIFO”) method. Certain steel inventories used by the Water Transmission Group are valued using the last-in, first-out (“LIFO”) method. Significant changes in steel levels or steel prices could materially impact the Company’s financial statements. Reserves are established for excess, obsolete and rework inventories based on estimates of salability and forecasted future demand. Management records an allowance for doubtful accounts receivable based on historical experience and expected trends. A significant reduction in demand or a significant worsening of customer credit quality could materially impact the Company’s consolidated financial statements.

Investments in unconsolidated affiliates over which the Company has significant influence are accounted for under the equity method of accounting, whereby the investment is carried at the cost of acquisition, including subsequent capital contributions and loans from the Company, plus the Company’s equity in undistributed earnings or losses since acquisition. Investments in affiliates which the Company does not have the ability to exert significant influence over the investees’ operating and financing activities are accounted for under the cost method of accounting. The Company’s former investment in TAMCO, a steel mini-mill in California, is accounted for under the equity method. Investments in Ameron Saudi Arabia, Ltd. and Bondstrand, Ltd. are accounted for under the cost method due to Management’s current assessment of the Company’s influence over these affiliates. The Company’s investment in TAMCO was sold in October 2010. Property, plant and equipment is stated on the basis of cost and depreciated principally using a straight-line method based on the estimated useful lives of the related assets, generally three to 40 years. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. If the estimated future, undiscounted cash flows from the use of an asset are less than its carrying value, a write-down is recorded to reduce the related asset to estimated fair value. Actual cash flows may differ significantly from estimated cash flows. Additionally, current estimates of future cash flows may differ from subsequent estimates of future cash flows. Changes in estimated or actual cash flows could materially impact the Company’s consolidated financial statements.

The Company is self insured for a portion of the losses and liabilities primarily associated with workers’ compensation claims and general, product and vehicle liability. Losses are accrued based upon the Company’s estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. The estimate of self-insurance liability includes

an estimate of incurred but not reported claims, based on data compiled from historical experience. Actual experience could differ significantly from these estimates and could materially impact the Company’s consolidated financial statements. The Company typically purchases varying levels of third-party insurance to cover losses subject to retention levels (deductibles or primary self insurance) and aggregate limits. Currently, the Company’s retention levels are $1.0 million per workers’ compensation claim, $.1 million per general, property or product liability claim, and $.25 million per vehicle liability claim.

When accounting for pension and other postretirement benefits, assumptions are made regarding the valuation of benefit obligations and the performance of plan assets that are controlled and invested by third-party custodians. Delayed recognition of differences between actual results and expected or estimated results is a guiding principle of these

standards. Such delayed recognition provides a gradual recognition of benefit obligations and investment performance over the working lives of the employees who benefit under the plans, based on various assumptions. Assumed discount rates are used to calculate the present values of benefit payments which are projected to be made in the future, including projections of increases in employees’ annual compensation and health care costs. Management also projects the future returns on invested assets based principally on prior performance. These projected returns reduce the net benefit costs the Company records in the current period. Actual results could vary significantly from projected results, and such deviations could materially impact the Company’s consolidated financial statements. Management consults with the Company’s actuaries when determining these assumptions. Program changes, including termination, freezing of benefits or acceleration of benefits, could result in an immediate recognition of unrecognized benefit obligations; and such recognition could materially impact the Company’s consolidated financial statements.

For pension and other postretirement benefits accounting, the discount rate is based on market interest rates. At November 30, 2010, the Company decreased the annual discount rate from 5.70% to 5.30% as a result of the then-current market interest rates on long-term, fixed-income debt securities of highly-rated corporations. In estimating the expected return on assets, the Company considers past performance and future expectations for various types of investments, as well as the expected long-term allocation of assets. At November 30, 2010, the Company maintained the long-term annual rate of return on assets assumption of 8.50% reflecting current expectations for future returns in the investment markets. In projecting the rate of increase in compensation levels, the Company considers movements in inflation rates as reflected by market interest rates. At November 30, 2010, the Company decreased the assumed annual rate of compensation from 4.25% to 3.50%. In selecting the rate of increase in health care costs, the Company considers past performance and forecasts of future health care cost trends. At November 30, 2010, the Company raised the annual rate of increase in health care costs to 10.00%, from 9.00% in 2009, decreasing ratably until reaching 5.00% in 2015 and beyond.

Different assumptions would impact the Company’s projected benefit obligations and annual net periodic benefit costs related to pensions and the accrued other benefit obligations and benefit costs related to postretirement benefits. The following reflects the impact associated with a change in certain assumptions:

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The Company utilizes market data or assumptions that the Company believes market participants would use in pricing assets or liabilities, including assumptions about risk and the risks inherent in the inputs to valuation techniques. These inputs can be readily observable, market corroborated or generally unobservable. The Company primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company classifies fair value balances based on the observability of those inputs. The ultimate exit price could be significantly different than currently estimated by the Company.

Management incentive compensation is accrued based on current estimates of the Company’s ability to achieve short-term and long-term performance targets. The Company’s actual performance and incentive compensation payouts could be significantly different than currently estimated by the Company.

Deferred income tax assets and liabilities are computed for differences between the financial statement and income tax bases of assets and liabilities. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred income tax assets to the amounts expected to be realized. Quarterly income taxes are estimated based on the mix of income by jurisdiction forecasted for the full fiscal year. The Company believes that it has adequately provided for tax-related matters. Actual income, the mix of income by jurisdiction and income taxes could be significantly different than currently estimated.

The amount of income taxes the Company pays is subject to ongoing audits by federal, state and foreign tax authorities. The Company’s estimate of the potential outcome of any uncertain tax issue is subject to Management’s assessment of relevant risks, facts, and circumstances existing at that time, with a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. A liability is recorded for the difference between the measured benefit recognized and the tax position taken or expected to be taken on the tax return. To the extent that the Company’s assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. The Company reports tax-related interest and penalties as a component of income tax expense.

LIQUIDITY AND CAPITAL RESOURCES

The following discussion of liquidity and capital resources combines the impact of both continuing and discontinued operations unless otherwise noted.

As of November 30, 2010, the Company’s working capital, including cash and cash equivalents and current portion of long-term debt, totaled $322.5 million, an increase of $35.0 million from working capital of $287.5 million as of November 30, 2009. The increase in working capital resulted primarily from higher cash and cash equivalents and inventory and lower accrued liabilities, partially offset by lower receivables and higher trade payables and income taxes payable. Inventories and payables rose due to the anticipated level of sales in 2011, while receivables fell due to the lower level of sales activity during 2010. Income taxes payable increased due to higher pretax income. Cash and cash equivalents totaled $236.7 million as of November 30, 2010, compared to $181.1 million as of November 30, 2009.

Net cash of $52.2 million was generated from operating activities in 2010, compared to $125.9 million generated in 2009. In 2010, cash from operating activities included net income of $46.3 million, less non-cash adjustments (depreciation, amortization, deferred income taxes, loss from affiliate, gain from sale of assets, stock compensation expense and the non-cash write-down of assets) of $18.7 million, plus changes in operating assets and liabilities of $24.6 million. In 2009, cash from operating activities included net income of $33.3 million, plus similar non-cash adjustments of $45.3 million, plus changes in operating assets and liabilities of $47.2 million. In 2008, cash from operating activities included net income of $58.6 million, plus similar non-cash adjustments (other than write-down of assets) of $22.5 million, plus changes in operating assets and liabilities of $7.4 million. Compared to 2009, non-cash adjustments in 2010 were lower due primarily to the sale of the Company’s ownership of TAMCO; and the net operating assets were lower primarily due to a leveling of business activity. The $73.7 million decline in net cash from operations from 2009 to 2010 was due to a sharp decline in business activity from 2008 to 2009, which did not repeat in 2010. In addition, cash from operations increased $37.4 million in 2009, compared to 2008, due to this economic slowdown.

Net cash provided by investing activities totaled $49.5 million in 2010, compared to net cash used in investing activities of $69.9 million in 2009 and $59.1 million in 2008. In 2010, net cash provided by investing activities consisted of gross proceeds from the sale of the Company’s investment in TAMCO of $78.1 million, other asset sales of $.9 million and a $1.5 million net repayment of loans by TAMCO; offset by capital expenditures of $31.0 million. In addition to normal replacement and upgrades of machinery and equipment, the Company expanded fiberglass pipe plants in Texas and Brazil in 2010 and 2009. Normal replacement expenditures are typically equal to depreciation. In 2009, net cash used in investing activities consisted of capital expenditures of $46.9 million, and $25.0 million of capital and loans to TAMCO. Net cash used in investing activities in 2009 was offset by proceeds of $2.0 million from the sale of assets. In 2008, net cash used in investing activities included capital expenditures of $60.7 million, which included the normal replacement and upgrades of machinery, the expansion of a wind tower manufacturing facility and expenditures for construction of new fiberglass pipe plants in Brazil. Net cash used in investing activities in 2008 was offset by proceeds of $1.6 million from the sale of assets. During the year ending November 30, 2011, the Company anticipates spending between $40.0 and $50.0 million on capital expenditures. Capital expenditures are expected to be funded by existing cash balances, cash generated from operations or additional borrowings.

During 2010, the Company received $1.5 million in loan repayments from TAMCO as part of a $40.0 million senior secured credit facility provided by TAMCO’s shareholders. During 2009, the Company contributed capital of $10.0 million to TAMCO. As of November 30, 2009, TAMCO had borrowed $30.0 million under the facility, of which $15.0 million was provided by the Company. On October 21, 2010, the Company sold its ownership in TAMCO which included the extinguishment of the senior secured credit facility.

Net cash used in financing activities totaled $47.4 million during 2010, compared to $28.8 million in 2009. Net cash used in 2010 consisted of net payment of debt of $8.0 million, payment of Common Stock dividends of $38.7 million and treasury stock purchases of $1.1 million (related to the payment of taxes associated with the vesting of restricted shares), offset by $.4 million provided by the issuance of Common Stock. The 2010 Common Stock dividends included a special dividend of $3.00 per

share, totaling $27.6 million, which was paid on November 30, 2010. Net cash used in 2009 consisted of net payment of debt of $16.5 million, payment of Common Stock dividends of $11.1 million, payments for debt issuance costs of $1.1 million and similar treasury stock purchases of $1.0 million. Also in 2009, the Company recognized tax benefits related to stock-based compensation of $.8 million. Net cash used in 2008 consisted of net payments of debt of $21.1 million, payment of Common Stock dividends of $10.5 million and similar treasury stock purchases of $2.6 million. Also in 2008, the Company received $.4 million from the issuance of Common Stock related to exercised stock options and recognized tax benefits related to stock-based compensation of $1.3 million.

The Company maintains a $100.0 million revolving credit facility with six banks (the “Revolver”). Under the Revolver, the Company may, at its option, borrow up to the available amount at floating interest rates (at a rate of LIBOR plus a spread ranging from 2.75% to 3.75%, based on the Company’s financial condition and performance) or utilize for letters of credit, at any time until August 2012, when all borrowings under the Revolver must be repaid and letters of credit cancelled. At November 30, 2010, $82.8 million was available under the Revolver.

The Company’s lending agreements contain various restrictive covenants, including the requirement to maintain specified amounts of net worth and restrictions on cash dividends, borrowings, liens, investments, capital expenditures, guarantees, and financial covenants. The Company is required to maintain consolidated net worth of $375.5 million plus 50% of net income and 75% of proceeds from any equity issued after November 30, 2008. The Company’s consolidated net worth exceeded the covenant amount by $142.4 million as of November 30, 2010. The Company is required to maintain a consolidated leverage ratio of consolidated funded indebtedness to earnings before interest, taxes, depreciation and amortization (“EBITDA”) of no more than 2.50 times. At November 30, 2010, the Company maintained a consolidated leverage ratio of .58 times EBITDA. Lending agreements require the Company to maintain qualified consolidated tangible assets at least equal to the outstanding secured funded indebtedness. At November 30, 2010, qualifying tangible assets equaled 5.52 times funded indebtedness. Under the most restrictive fixed charge coverage ratio, the sum of EBITDA and rental expense less cash taxes must be at least 1.50 times the sum of interest expense, rental expense, dividends and scheduled funded debt payments. At November 30, 2010, the Company maintained such a fixed charge coverage ratio of 2.04 times.

FINANCIAL SECTION

Under the most restrictive provisions of the Company’s lending agreements, $8.6 million of retained earnings were not restricted at November 30, 2010, as to the declaration of cash dividends or the repurchase of Company stock. In addition, the Company has received consents from its lenders to purchase up to $50.0 million of the Company’s Common Stock. At November 30, 2010, the Company was in compliance with all covenants of its various lending agreements.

Cash and cash equivalents at November 30, 2010 totaled $236.7 million, an increase of $55.6 million from November 30, 2009. At November 30, 2010, the Company had total debt outstanding of $31.1 million, compared to $38.3 million at November 30, 2009, and $111.3 million in unused committed and uncommitted credit lines available from foreign and domestic banks. The Company’s highest borrowing and the average borrowing levels during 2010 were $39.5 million and $37.9 million, respectively.

Cash balances are held throughout the world, including $65.3 million held outside of the U.S. at November 30, 2010. Most of the amounts held outside of the U.S. could be repatriated to the U.S. but, under current law, would be subject to U.S. federal income taxes, less applicable foreign tax credits. The Company currently plans to indefinitely maintain significant cash balances outside the U.S.

The Company also owns life insurance policies on current and former executives. The fair value of these policies is equal to the cash surrender value as determined by the insurance companies, which totaled $27.5 million, as of November 30, 2010.

The Company contributed $12.0 million to the U.S. defined-benefit pension plan and $2.2 million to the non-U.S. defined-benefit pension plans in 2010. The Company expects to contribute approximately $11.4 million to its U.S. defined-benefit pension plan and $1.4 million to the non-U.S. defined-benefit pension plans in 2011.

Management believes that cash flow from operations and current cash balances, together with currently available lines of credit, will be sufficient to meet operating requirements in 2011. Cash available from operations could be affected by a general economic downturn or a decline or adverse changes in the Company’s business, such as a loss of customers, competitive pricing pressures or significant raw material price increases. The Company’s contractual obligations and commercial commitments at November 30, 2010 are summarized as follows (in thousands):

RESULTS OF OPERATIONS: 2010 COMPARED WITH 2009

General

Net income totaled $46.3 million, or $5.00 per diluted share, on sales of $503.3 million in the year ended November 30, 2010, compared to $33.3 million, or $3.61 per diluted share, on sales of $546.9 million in 2009. A sales increase by the Fiberglass-Composite Pipe Group partially offset larger declines by the Water Transmission and Infrastructure Products Groups. The Fiberglass-Composite Pipe Group benefited from increased demand in energy markets, but income decreased due to lower margins. Water Transmission Group’s sales and income declined primarily due to lower wind tower sales. Infrastructure Products Group’s profits were lower as sales continued to be impacted by weak construction spending. Net income increased in 2010 due primarily to the gain on the sale of the Company’s investment in TAMCO, the Company’s 50%-owned steel mini-mill, and lower equity in TAMCO’s losses.

Sales

Sales decreased $43.7 million, or 8.0%, in 2010, compared to 2009. Sales declined due to depressed conditions in wind energy markets and softness in water pipe markets which impacted the Water Transmission Group and continued weakness in most construction markets in Hawaii and in pole demand which impacted the Infrastructure Products Group, partially offset by increased demand in the Fiberglass-Composite Pipe Group.

Fiberglass-Composite Pipe’s sales increased $18.6 million, or 8.3%, in 2010, compared to 2009. Sales of operations in the U.S. increased $19.4 million primarily due to demand in key onshore oilfield and mining markets. Sales of Asian operations decreased $8.8 million, in spite of the weaker U.S. dollar, due to the decline in marine and offshore markets. European-originated sales decreased $5.6 million primarily due to softer market conditions in industrial and oilfield markets. Sales of Brazilian operations increased $13.6 million due to the startup of a new onshore oilfield pipe plant, growth in the municipal water market and the rising value of the Brazilian currency. Orders for marine and offshore projects continue to soften; however, looking forward, the Fiberglass-Composite Pipe Group continues to see strong demand due primarily to energy-related projects.

Water Transmission Group’s sales decreased $39.4 million, or 22.2%, in 2010, compared to 2009. The decrease was largely due to lower wind tower sales and partly due to weaker cyclical demand for water pipe in the western U.S. As of November 30, 2010, the wind tower backlog totaled $3.4 million, from $28.9 million at the end of 2009, due to production throughout 2010 and the lack of new orders. Until the wind energy markets improve and more financing becomes available to the wind energy industry, the Group’s wind tower activity is expected to remain depressed. Near term, the water pipe business is also expected to continue to experience soft market demand. The timing of bid activity has been negatively affected by the economy, municipal budgets and availability of financing. The Company continues to monitor a number of major wind tower and pipe projects; however, it remains uncertain when owners, water agencies and municipalities will proceed with these projects.

Infrastructure Products’ sales decreased $23.0 million, or 15.9%, in 2010, compared to 2009. Both the Hawaii Division and the Pole Products Division had lower sales in 2010. The Hawaii Division continued to experience lower demand for aggregates and ready-mix concrete on both Oahu and Maui as construction spending remained weak due to the recessionary economy. Construction related to military and governmental spending provided a stable base of business, while all other sectors declined. The decline in U.S. housing markets and reduced demand for concrete lighting poles for new construction and steel traffic poles impacted the Pole Products Division. The Infrastructure Products Group is expected to continue to be affected by the slowdown in construction spending in Hawaii and the low level of residential construction spending throughout the U.S. Demand for Pole Products Division’s decorative concrete poles for residential lighting applications appears to have stabilized. However, major recoveries of the residential construction markets and the Infrastructure Products Group are not expected in the near term.

Gross Profit

Gross profit in 2010 was $127.9 million, or 25.4% of sales, compared to $145.5 million, or 26.6% of sales, in 2009. Gross profit decreased $17.5 million, primarily due to lower sales, lower margins and higher last-in, first-out (“LIFO”) reserves related to steel used by the Water Transmission Group.

Fiberglass-Composite Pipe Group’s gross profit decreased $2.9 million in 2010, compared to 2009. Profit margins decreased to 37.1% in 2010, compared to 41.4% in 2009. Margins were lower due to higher raw material costs and changes in product mix, with completion of higher-margin projects from Asia and an increase in lower-margin sales from Brazil. Higher sales increased gross profit by $7.7 million, offset by unfavorable product mix and operating efficiencies of $10.6 million.

Water Transmission Group’s gross profit decreased $4.5 million in 2010, compared to 2009, due to lower sales. Profit margins increased to 12.1% in 2010, compared to 11.9% in 2009. Overall, gross profit margins remained stable as lower raw material costs were offset by unfavorable plant efficiencies. The decline in the Group’s gross profit was primarily related to wind towers. As a result of the depressed market for wind towers, Management performed an impairment analysis at the end of the third quarter of 2010 of certain wind tower assets.

32

FINANCIAL SECTION

Based on internal and third-party forecasts, the estimated future undiscounted cash flows of the wind tower facility exceed the carrying value of the related long-lived assets. However, if market conditions do not improve as expected, this could indicate a potential impairment of the Company’s long-lived assets used for the production of wind towers. No events or circumstances occurred since August 29, 2010, that indicate that the carrying amounts of these assets may not be recoverable.

Gross profit in the Infrastructure Products Group decreased $4.5 million in 2010, compared to 2009. Profit margins remained steady at 19.2%. The decline in gross profit was related to lower sales.

Consolidated gross profit was $6.1 million lower in 2010 than in 2009 due to unfavorable reserves in 2010 associated with LIFO accounting of certain steel inventories used by the Water Transmission Group due primarily to an increase in steel prices. LIFO reserves are not allocated to the operating segments.

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses totaled $101.8 million, or 20.2% of sales, in 2010, compared to $100.0 million, or 18.3% of sales, in 2009. The $1.8 million increase was due to higher pension expense of $4.7 million, higher expenses of international operations related to changes in foreign exchange rates of $1.8 million, higher depreciation expense of $1.0 million, higher severance of $.8 million, and higher compensation expense of $.5 million, offset by lower insurance costs of $4.5 million, lower legal and professional fees of $1.2 million and lower other expenses of $1.3 million.

Gain from Sale of Investment in Affiliate

The sale of the Company’s 50% ownership of TAMCO was completed on October 21, 2010. The Company sold its TAMCO investment and extinguished all outstanding debt owed by TAMCO to the Company under a shareholder loan. The Company received $78.1 million of gross proceeds after estimated working capital adjustments of $.7 million and before closing costs of approximately $2.1 million, recognizing a pretax gain of $48.4 million.

Other Income, Net

Other income, net, totaled $3.6 million in 2010, compared to $7.4 million in 2009. The decrease in other income was due primarily to lower dividends from affiliates of $2.9 million and lower scrap inventory sales of $1.2 million, partially offset by foreign currency transactions of $.6 million.

Interest Income, Net

Net interest income totaled $22,000 in 2010, compared to $.6 million in 2009. The decline was primarily due to an increase of $.4 million in interest expense and higher bank fees. Interest income decreased by $.2 million in 2010 due to lower investment yields on short-term investments.

Provision for Income Taxes

Income taxes increased to $29.7 million in 2010, from $15.5 million in 2009. The effective tax rate on income from continuing operations increased to 38.0% in 2010, from 29.0% in 2009. The effective rate in 2010 was reduced by a $.6 million decrease in the valuation allowance for deferred assets related to delayed bonuses and restricted stock. The decrease represented a correction of an amount recorded in 2009. The effective tax rate in 2009 was reduced by tax benefits of $1.2 million associated with the adjustment to a deferred tax liability related to earnings and profits from the Company’s former New Zealand subsidiary. The $1.2 million adjustment represented a correction of an amount recorded in prior period financial statements. Management believes these corrections to be immaterial to prior interim and annual financial statements. For both 2009 and 2010, the Company provided a full valuation allowance for the net operating loss carry-overs of its foreign subsidiaries except its subsidiary in the Netherlands. In 2009, the Company released $1.3 million of valuation allowance for deferred tax assets related to the Netherlands subsidiary as a result of higher profitability in 2008 and projected future profitability. In 2010, the fourth-quarter tax rate was significantly higher than the statutory rate due, in part, to an increase in the valuation allowance related to the Netherlands subsidiary of $3.1 million as a result of a revision to profitability projections. During the fourth quarter of 2010, the Company implemented a plan to repatriate $44.2 million of the undistributed earnings of its subsidiary in Singapore at a relatively low tax rate due to the realization of previously unrecognized foreign tax credits. The net tax expense in 2010 related to this repatriation was $1.7 million.

Equity in Loss of Affiliate, Net of Taxes

Equity in loss of affiliate, which consists of the Company’s share of the net loss of TAMCO, decreased to a loss of $1.2 million in 2010, compared to a loss of $5.5 million in 2009. Equity income is shown net of income taxes at an effective rate of 7.8% in 2010 and 2009, respectively, reflecting the dividend exclusion provided to the Company under tax laws. TAMCO’s losses were due to the collapse of infrastructure spending for steel rebar in California, Arizona and Nevada which began in late 2008. During 2010, the Company recognized losses for TAMCO until the sale of its 50% ownership on October 21, 2010.

(Loss)/Income from Discontinued Operations, Net of Taxes

In 2006, the Company completed the sale of the Coatings Business to PPG Industries, Inc. (“PPG”). As part of the sale, PPG agreed to pay to the Company future dividends from Oasis-Ameron, Ltd. (“OAL”), a former affiliate of the Company held by the Coatings Business, up to the amount of OAL’s unremitted earnings at the time of the sale of the Coatings Business to PPG. In 2009, the Company recorded $1.2 million, net of tax, from PPG in exchange for any claims on OAL’s dividends. Also in 2009, the Company wrote down by $.4 million, net of tax, real property located in Hull, England formerly used by the Coatings Business and currently held for sale. In 2010, the Company further wrote down the property by an additional $1.0 million, net of tax. The real property write-downs were due to declining real estate values.

RESULTS OF OPERATIONS: 2009 COMPARED WITH 2008

General

Net income totaled $33.3 million, or $3.61 per diluted share, on sales of $546.9 million in the year ended November 30, 2009, compared to $58.6 million, or $6.35 per diluted share, on sales of $667.5 million in 2008. The Fiberglass-Composite Pipe Group had lower sales and profits due primarily to continued soft market conditions and foreign exchange. Water Transmission Group’s sales declined due to weak demand, but profitability improved due principally to better project cost control and plant efficiencies. The Infrastructure Products Group had lower sales and income due to the decline in both the Pole Products Division and the Hawaii Division associated with continued weak construction spending throughout the U.S. Equity in earnings of TAMCO decreased by $15.8 million in 2009, compared to 2008, due to the decline in the steel rebar market in California, Arizona and Nevada.

Sales

Sales decreased $120.6 million, or 18.1%, in 2009, compared to 2008. Sales decreased due to generally weaker economic conditions affecting all of the Company’s businesses.

Fiberglass-Composite Pipe’s sales decreased $48.7 million, or 17.8%, in 2009, compared to 2008. Sales from operations in the U.S. decreased $21.7 million in 2009 primarily due to weaker oilfield piping demand and weak industrial markets. Sales from Asian subsidiaries decreased $13.7 million in 2009, driven by weaker conditions in Middle Eastern industrial markets and the impact of foreign exchange. Sales from European operations decreased $8.7 million in 2009 primarily due to softer market conditions in Europe, North Africa and Russia and weaker foreign currencies in 2009 than in 2008. Sales from Brazilian operations decreased $4.6 million in 2009, due to the impact of foreign exchange, project delays in municipal water markets, and a halt in activity in the pulp and paper market. Worldwide demand declined in key onshore oilfield, chemical and industrial market segments. However, marine and offshore markets remained strong, sustained by new vessel construction at Asian shipyards.

Water Transmission Group’s sales decreased $38.0 million, or 17.7%, in 2009, compared to 2008. The sales decrease was primarily due to weaker demand for water pipe in the western United States and completion of large orders in Colombia during 2008. Wind tower sales remained steady in 2009, compared to prior year.

Infrastructure Products’ sales decreased $34.8 million, or 19.4%, in 2009, compared to 2008. The Company’s Hawaii Division had lower sales as residential and commercial construction markets in Hawaii contracted. Demand for aggregates and ready-mix concrete on both Oahu and Maui declined as construction spending continued to soften due to the recessionary economy. Military and governmental spending held steady in Hawaii. The Pole Products Division continued to be impacted by the decline in U.S. housing markets and reduced demand for concrete lighting poles and steel traffic poles.

Gross Profit

Gross profit in 2009 was $145.5 million, or 26.6% of sales, compared to $153.6 million, or 23.0% of sales, in 2008. Gross profit decreased $8.2 million in 2009, compared to 2008, due to lower sales offset by better cost control, improved plant efficiencies, lower LIFO reserves, favorable product mix and lower raw material costs.

Fiberglass-Composite Pipe Group’s gross profit decreased $14.8 million in 2009, compared to 2008. Profit margins improved to 41.4% in 2009, compared to 39.5% in 2008. Margins were higher in 2009 due to favorable product mix, plant efficiencies and lower raw material costs. Decreased sales, from lower volume and prices, reduced gross profit by $19.2 million, offset by favorable product mix and operating efficiencies of $4.4 million in 2009.

Water Transmission Group’s gross profit increased $17.3 million in 2009, compared to 2008. Profit margins increased to 11.9% in 2009, compared to 1.8% in 2008. Improved profit margins resulted from plant efficiencies with the completion of newly-constructed wind tower facility, cost controls and completion of low-margin pipe projects in 2008.

Gross profit in the Infrastructure Products Group decreased $11.5 million in 2009, compared to 2008. Profit margins declined to 19.2% in 2009, compared to 21.9% in 2008. Margins were lower in 2009 due to pricing pressures related to challenging market conditions. Lower sales negatively impacted gross profit by $7.6 million in 2009, while lower margins primarily related to unfavorable plant utilization decreased gross profit by an additional $3.9 million in 2009.

34

FINANCIAL SECTION

Consolidated gross profit was $2.1 million higher in 2009 than in 2008 due to decreased reserves in 2009 associated with LIFO accounting of certain steel inventories used by the Water Transmission Group due to lower LIFO inventory quantities and a decrease in steel prices.

Selling, General and Administrative Expenses

SG&A totaled $100.0 million, or 18.3% of sales, in 2009, compared to $98.2 million, or 14.7% of sales, in 2008. The $1.8 million increase in SG&A was due to higher pension expense of $8.0 million, higher legal expenses of $1.9 million, due primarily to the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) inquiry, offset by lower stock compensation costs of approximately $2.2 million, favorable foreign exchange impact of $1.8 million, lower insurance premiums of $1.6 million and lower other expenses of $2.5 million.

Other Income, Net

Other income totaled $7.4 million in 2009, compared to $8.2 million in 2008. The decrease in other income in 2009 was due primarily to higher dividends from affiliates of $.8 million, higher gains on asset sales of $.5 million, and lower foreign currency losses of $.2 million, more than offset by $.5 million lower royalties and $1.8 million lower scrap inventory sales.

Interest

Net interest totaled $.6 million in 2009, compared to $1.5 million in 2008. Interest income was $1.1 million in 2009, a decrease of $2.7 million compared to 2008, due to lower interest rates on short-term investments. Interest expense declined from $.5 million in 2009 to $2.3 million in 2008, due to lower debt levels.

Provision for Income Taxes

Income taxes decreased to $15.5 million in 2009, from $17.0 million in 2008. The effective tax rate on income from continuing operations increased to 29.0% in 2009, from 26.0% in 2008. The effective tax rate in 2009 was reduced by tax benefits of $1.2 million associated with the adjustment to a deferred tax liability related to earnings and profits from the Company’s former New Zealand subsidiary. The effective tax rate in 2008 was reduced by tax benefits of $2.9 million associated with tax years no longer subject to audit and settlement of the 2005-2006 Internal Revenue Service (“IRS”) examinations. For both 2008 and 2009, the Company provided a full valuation allowance for the net operating loss carry-overs of its foreign subsidiaries except its subsidiary in the Netherlands. The Company released $1.3 million in 2009 and $1.1 million in 2008 of valuation allowance for deferred tax assets related to the Netherlands subsidiary due to profitability in 2008 and projected future profitability.

Equity in Earnings of Affiliate, Net of Taxes

Equity in earnings of affiliate, which consists of the Company’s share of the net income or loss of TAMCO, decreased to a loss of $5.5 million in 2009, compared to income of $10.3 million in 2008. Equity income is shown net of income taxes at an effective rate of 7.8% and 9.6% in 2009 and 2008, respectively. The decline in TAMCO’s earnings was due to the collapse of infrastructure spending for steel rebar in California, Arizona and Nevada. TAMCO halted production in the first quarter of 2009 and had limited production during the remainder of 2009.

Income from Discontinued Operations, Net of Taxes

Income from discontinued operations totaled $.8 million in 2009, net of taxes.

OFF-BALANCE SHEET FINANCING

The Company does not have any off-balance sheet financing, other than listed in the Liquidity and Capital Resources section herein. All of the Company’s subsidiaries are included in the financial statements, and the Company does not have relationships with any special purpose entities.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Risk

The Company operates internationally, giving rise to exposure to market risks from changes in foreign exchange rates. From time to time, the Company borrows in various currencies to reduce the level of net assets subject to changes in foreign exchange rates or purchases foreign exchange forward and option contracts to hedge firm commitments, such as receivables and payables, denominated in foreign currencies. The Company does not use the contracts for speculative or trading purposes. At November 30, 2010, the Company had four foreign currency forward contracts expiring at various dates through February 14, 2011 with a fair value loss of less than $.1 million. Such instruments are carried at fair value, with related adjustments recorded in other income.

Debt Risk

The Company can have variable-rate, short-term and long-term debt as well as fixed-rate, long-term debt. The fair value of the Company’s fixed-rate debt is subject to changes in interest rates. The estimated fair value of the Company’s variable-rate debt approximates the carrying value of such debt since the variable interest rates are market-based and the Company believes such debt could be refinanced on materially similar terms. The Company is subject to the availability of credit to support new requirements and to refinance long-term and short-term debt.

35

AMERON INTERNATIONAL

At November 30, 2010, the estimated fair value of notes payable by the Company’s wholly-owned subsidiary in Singapore totaling approximately $15.4 million, with a fixed rate of 4.25% per annum, was $16.4 million. These notes must be repaid in installments of approximately $7.7 million per year. The Company had $7.2 million of variable-rate industrial development bonds payable at an interest rate of .49% per annum at November 30, 2010, payable in 2016. The Company also had $8.5 million of variable-rate industrial development bonds payable at an interest rate of .49% per annum at November 30, 2010, payable in 2021. The industrial revenue bonds are supported by standby letters of credit issued under the Revolver, which has a scheduled maturity of August 2012.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of Ameron International Corporation and all wholly-owned subsidiaries (“Ameron” or the “Company”). All material intercompany accounts and transactions have been eliminated.

Reclassifications

Certain prior-year balances have been reclassified to conform with the current-year presentation.

Use of Estimates

The preparation of financial statements in conformity with United States Generally Accepted Accounting Principles (“GAAP”) requires Management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Significant estimates include revenue and costs recorded under percentage-of-completion accounting, assumptions related to benefit plans and reserves associated with management incentives, receivables, inventories, income taxes, self insurance and environmental and legal contingencies. Actual results could differ from those estimates.

Revenue Recognition

Revenue for the Fiberglass-Composite Pipe and Infrastructure Products segments is recognized when risk of ownership and title pass, primarily at the time goods are shipped, provided that an agreement exists between the customer and the Company, the price is fixed or determinable and collection is reasonably assured. Revenue is recognized for the Water Transmission Group primarily under the percentage-of-completion method, typically based on completed units of production, since products are manufactured under enforceable and binding construction contracts, are typically designed for specific applications, are not interchangeable between projects, and are not manufactured for stock. In those cases in which products are manufactured for stock or are not related to specific construction contracts, revenue is recognized under the same criteria used by the other two segments. Revenue under the percentage-of-completion method is subject to a greater level of estimation, which affects the timing of revenue recognition, costs and profits. Estimates are reviewed on a consistent basis and are adjusted periodically to reflect current expectations. Costs attributable to unpriced change orders are treated as costs of contract performance in the period, and contract revenue is recognized if recovery is probable. Disputed or unapproved change orders are treated as claims. Recognition of amounts of additional contract revenue relating to claims occurs when amounts have been received or awarded with recognition based on the percentage-of-completion methodology.

Research and Development Costs

Research and development costs, which relate primarily to the development, design and testing of products, are expensed as incurred. Such costs, which are included in selling, general and administrative expenses, were $2,759,000 in 2010, $5,969,000 in 2009, and $4,347,000 in 2008.

Environmental Clean-up Costs and Other Claims

The Company expenses environmental clean-up costs related to existing conditions resulting from past or current operations on a site-by-site basis. Liabilities and costs associated with these matters, as well as other pending litigation and asserted claims arising in the ordinary course of business, require estimates of future costs and judgments based on the knowledge and experience of Management and the Company’s legal counsel. When the Company’s exposures can be reasonably estimated and are probable, liabilities and expenses are recorded.

Income Taxes

Deferred income tax assets and liabilities are computed for differences between the financial statement and income tax bases of assets and liabilities. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to reverse. Valuation allowances are established to reduce deferred income tax assets to the amounts expected to be realized.

The Company is subject to income taxes in the U.S. and in numerous foreign jurisdictions. Judgments, estimates and assumptions are required in determining tax return reporting positions and in calculating provisions for income taxes, which are based on interpretations of tax regulations and accounting pronouncements. Liabilities are established for uncertain tax positions when it is more likely than not that such positions will be challenged and may not be sustained upon review by taxing authorities. These liabilities are established through the income tax provisions and are recorded as liabilities on the consolidated balance sheets. These liabilities are recalculated as governing laws and facts and circumstances change, such as the closing of a tax audit or the expiration of the statute of limitations for a specific exposure.

Earnings Per Share

Basic and diluted net income per share are computed using the two-class method which allocates earnings to both Common Stock and participating securities. Under the two-class method, unvested restricted Common Stock with non-forfeitable rights to dividends are considered participating securities. Dividends from such participating securities are excluded from net income allocated to Common Stock for purposes of the two-class method calculation.

Basic shares are computed on the basis of the weighted-average number of shares of Common Stock outstanding during the periods presented. Diluted shares are computed on the basis of the weighted-average number of shares of Common Stock outstanding plus the effect of outstanding stock options and restricted stock using the treasury stock method. Stock options and restricted stock of 19,286, 39,483 and 58,802 shares are excluded from the below calculation for the years ended November 30, 2010, 2009 and 2008, respectively, as inclusion would be anti-dilutive.

Following is a reconciliation of net income allocated to Common Stock, using the two-class method, and the weighted-average number of shares used in the computation of basic and diluted earnings per share allocated to Common Stock:

Cash and Cash Equivalents

Cash equivalents represent highly liquid investments with original maturities of three months or less when purchased. Total cash and cash equivalents were comprised of the following, as of November 30:

(In thousands) 2010 2009

Cash $ 21,066 $ 21,718 Money market funds 169,621 66,935 Time deposits 46,050 92,461 $ 236,737 $ 181,114

Inventory Valuation

Inventories are stated at the lower of cost or market with cost determined principally on the first-in, first-out (“FIFO”) method except for certain steel inventories used by the Water Transmission Group that are valued using the last-in, first-out (“LIFO”) method. Significant changes in steel levels or costs could materially impact the Company’s financial statements. Reserves are established for excess, obsolete and rework inventories based on estimates of salability and forecasted future demand.

Affiliates

Investments in unconsolidated affiliates over which the Company has significant influence are accounted for under the equity method of accounting, whereby the investment is carried at the cost of acquisition, including subsequent capital contributions and loans from the Company, plus the Company’s equity in undistributed earnings or losses since acquisition. Investments in

affiliates which the Company does not have the ability to exert significant influence over the investees’ operating and financing activities are accounted for under the cost method of accounting. The Company’s investment in TAMCO, a steel mini-mill in California, was accounted for under the equity method. On October 21, 2010, the Company completed the sale of its 50% ownership interest in TAMCO. Investments in Ameron Saudi Arabia, Ltd. and Bondstrand, Ltd. are accounted for under the cost method due to Management’s current assessment of the Company’s influence over these affiliates.

Property, Plant and Equipment

Items capitalized as property, plant and equipment, including improvements to existing facilities, are recorded at cost. Construction in progress represents capital expenditures incurred for assets not yet placed in service. Capitalized interest was $892,000 and $1,600,000 for the years ended November 30, 2010 and 2009, respectively. Amortization of capitalized interest totaled $792,000 and $701,000 for the years ended November 30, 2010 and 2009, respectively. Depreciation is computed principally using the straight-line method based on estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the life of the improvement or the term of the lease. Useful lives are as follows:

Useful Lives (in years)

Buildings 10-40 Machinery and equipment Autos, trucks and trailers 3-8 Cranes and tractors 5-15 Manufacturing equipment 3-15 Other 3-20

43

AMERON INTERNATIONAL

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. If the estimated future, undiscounted cash flows from the use of an asset are less than its carrying value, a write-down is recorded to reduce the related asset to estimated fair value. As a result of the depressed market for wind towers, Management performed an analysis at the end of the third quarter of 2010 of certain wind tower assets. Based on internal and third-party forecasts, the estimated future undiscounted cash flows of the wind tower facility exceed the carrying value of the related long-lived assets. However, if market conditions do not improve as expected, this could indicate a potential impairment of the Company’s long-lived assets used for the production of wind towers. No events or circumstances occurred since August 29, 2010, that indicate that the carrying amounts of these assets may not be recoverable.

Goodwill and Intangible Assets

Intangible assets are amortized on a straight-line basis over periods ranging from three to 15 years.

The cost of an acquired business is allocated to the acquired net assets based on the estimated fair values at the date of acquisition. The excess of the cost of an acquired business over the aggregate fair value is recorded as goodwill. Goodwill is not amortized, but instead tested for impairment at least annually. Such tests require Management to make estimates about future cash flows and other factors to determine the fair value of the respective assets.

The Company reviews the recoverability of intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. If the estimated, future, undiscounted cash flows from the use of an asset are less than its carrying value, a write-down is recorded to reduce the related asset to estimated fair value.

Self Insurance

The Company typically utilizes third-party insurance subject to varying retention levels (deductibles or primary self insurance) and aggregate limits. The Company is self insured for a portion of the losses and liabilities primarily associated with workers’ compensation claims and general, product and vehicle liability. Losses are accrued based upon the Company’s estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. The estimate of self-insurance liability includes an estimate of incurred but not

reported claims, based on data compiled from historical experience.

Foreign Currency Translation

The functional currencies for the Company’s foreign operations are the applicable local currencies. The translation from the applicable foreign currencies to U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using a weighted-average exchange rate during the period. The resulting translation adjustments are recorded in accumulated other comprehensive income/(loss). Translation adjustments arising from intercompany advances that are permanent in nature are also included in accumulated other comprehensive income/(loss). Gains or losses resulting from foreign currency transactions are included in other income, net.

Derivative Financial Instruments and Risk Management

The Company operates internationally, giving rise to exposure to market risks from changes in foreign exchange rates. From time to time, derivative financial instruments, primarily foreign exchange contracts, are used by the Company to reduce those risks. The Company does not hold or issue financial or derivative financial instruments for trading or speculative purposes. As of November 30, 2010 and 2009, the Company had foreign currency forward contracts with fair value losses of $16,000 and $16,000, respectively. The Company does not apply hedge accounting for these derivative financial instruments. Net changes in fair values of the underlying instruments are recognized in earnings.

Fair Value of Financial Instruments

The fair value of financial instruments, other than long-term debt or derivatives, approximates the carrying value because of the short-term nature of such instruments.

Concentration of Credit Risk

Financial instruments that subject the Company to credit risk consist primarily of cash equivalents, trade accounts receivable, and forward foreign exchange contracts. The Company records an allowance for doubtful accounts based on historical experience and expected trends. Credit risk with respect to trade accounts receivable is generally distributed over a large number of entities comprising the Company’s customer base and is geographically dispersed. The Company performs ongoing credit evaluations of its customers, maintains an allowance for doubtful accounts and, in certain limited instances, maintains credit insurance. The Company actively evaluates the creditworthiness of the financial institutions with which it conducts business. If the financial condition of the Company’s customers were to deteriorate, resulting in an inability to make payment, additional allowances may be required.

No customer individually accounted for 10% or more of total consolidated sales in 2010 or 10% or more of gross accounts receivable as of November 30, 2010 and 2009, respectively. In 2009, one customer individually accounted for approximately 12% of the Company’s total consolidated sales.

FINANCIAL SECTION

New Accounting Pronouncements

In June 2008, the Financial Accounting Standards Board (“FASB”) issued guidance requiring unvested instruments granted in share-based payment transactions that contain nonforfeitable rights to dividends or dividend equivalents to be accounted for as participating securities subject to the two-class method of computing earnings per share. All earnings per share data for periods prior to adoption are required to be adjusted retrospectively. The Company adopted the guidance as of December 1, 2009, and the adoption did not have a material effect on the Company’s consolidated financial statements. See above for a reconciliation of net income allocated to Common Stock using the two-class method.

In December 2008, the FASB issued revised guidance for employers’ disclosures about postretirement benefit plan assets effective for fiscal years ending after December 15, 2009. The FASB requires an employer to disclose investment policies and strategies, categories, fair value measurements, and significant concentration of risk among its postretirement benefit plan assets. The Company adopted the revised guidance as of November 30, 2010. Adoption did not have a material effect on the Company’s consolidated financial statements.

In June 2009, the FASB issued guidance to revise the approach to determine when a variable interest entity (“VIE”) should be consolidated. The new consolidation model for VIE’s considers whether the Company has the power to direct the activities that most significantly impact the VIE’s economic performance and shares in the significant risks and rewards of the entity. The guidance on VIE’s requires companies to continually reassess VIE’s to determine if consolidation is appropriate and provide additional disclosures. The Company adopted the guidance as of December 1, 2009, and adoption did not have a material effect on the Company’s consolidated financial statements.

In January 2010, the FASB required new disclosures about fair value of financial instruments for interim and annual reporting periods. These new disclosures were effective for interim and annual reporting periods beginning after December 15, 2009, except for disclosures about purchases, sales, issuances and settlements of Level 3 financial instruments, which are effective for interim and annual reporting periods in fiscal years beginning after December 15, 2010. Adoption is not expected to have a material effect on the Company’s consolidated financial statements.

NOTE 2 DISCONTINUED OPERATIONS

In 2006, the Company completed the sale of its Performance Coatings & Finishes business (the “Coatings Business”) to PPG Industries, Inc. (“PPG”). As part of the sale, PPG agreed to pay to the Company future dividends from Oasis-Ameron, Ltd. (“OAL”), a former affiliate of the Company held by the Coatings Business, up to the amount of OAL’s unremitted earnings at the time of the sale of the Coatings Business to PPG. In 2009, the Company recorded $1,232,000, net of tax, from PPG in exchange for any claims on OAL’s dividends. Also in 2009, the Company wrote down by $415,000, net of tax, real property located in Hull, England, formerly used by the Coatings Business and currently held for sale. In 2010, the Company wrote down the property by an additional $1,014,000, net of tax. The real property write downs were due to declining real estate values.

Certain steel inventories used by the Water Transmission Group are valued using the LIFO method. Inventories valued using the LIFO method comprised 8.7% and 14.8% of consolidated inventories at November 30, 2010 and 2009, respectively. During 2010, the LIFO reserve increased $2,114,000 primarily due to the rise in steel prices subject to valuation using the LIFO method. During 2009, the LIFO reserve decreased $3,984,000 due to lower steel prices, offset by a decrease in steel inventory. If inventories valued using the LIFO method were valued using the FIFO method, total inventories would have increased by $6,036,000 and increased by $3,922,000 at November 30, 2010 and 2009, respectively.

As of November 30, 2010, the Company had foreign net operating loss carry-overs of approximately $29,132,000. A full valuation allowance has been provided against these net operating losses except for $9,969,000 of net operating losses generated by the Company’s subsidiary in the Netherlands (these net operating loss carry-overs expire between 2012 and 2019). The Company assessed its ability to realize deferred tax assets (including its net operating losses in the Netherlands) and determined certain deferred tax assets were realizable and others were not realizable. The valuation allowance increased by $3,118,000 in 2010, compared to 2009, primarily due to certain deferred tax assets expiring unused in the Netherlands during their carry-over periods. In 2009, the Company released $1,269,000 of valuation allowance for deferred tax assets related to the Netherlands subsidiary as a result of higher profitability in 2008 and projected future profitability. The Company’s subsidiary in the Netherlands with net operating losses of $9,969,000 is projecting future taxable income and has an ongoing tax planning strategy to prevent a substantial portion of these net operating loss carry-overs from expiring unutilized. The balance of the valuation allowance applies to certain foreign deferred tax assets and certain other deferred tax assets that will likely not result in a tax benefit. The tax effects of the changes to the valuation allowance related to the Company’s foreign subsidiaries are included in foreign earnings taxed at different rates in the table below.

The tax provision from continuing operations represents effective tax rates of 38.0%, 29.0% and 26.0% of income from continuing operations before income taxes for the years ended November 30, 2010, 2009 and 2008, respectively. A reconciliation of income taxes provided at the effective income tax rate and the amount computed at the federal statutory income tax rate of 35.0% is as follows for the year ended November 30:

In 2010, the Company recorded a tax benefit of $599,000 associated with a decrease in the valuation allowance for deferred assets related to delayed bonuses and restricted stock and a $361,000 decrease in current taxes payable related to the same issue. These 2010 adjustments represent corrections of amounts recorded in 2009. In 2009, the Company recorded a tax benefit of $1,199,000 (included in foreign earnings taxed at different rates) associated with the adjustment to a deferred tax liability related to earnings and profits from the Company’s New Zealand subsidiary. The $1,199,000 adjustment in 2009 represents a correction of an amount recorded in prior period financial statements. Management believes these corrections to be immaterial to prior interim and annual financial statements.

During the fourth quarter of 2010, the Company implemented a plan to repatriate $44,190,000 of the undistributed earnings of its subsidiary in Singapore due to the realization of previously unrecognized foreign tax credits. The net tax expense in 2010 related to this repatriation was $1,713,000, which is net of a $1,509,000 deferred tax benefit that the Company will realize in connection with its 2011 federal income tax return as a result of the repatriation plan. This net tax expense is included in foreign earnings taxed at different rates in the table above. The Company intends to permanently reinvest the remaining undistributed earnings of its Singapore subsidiary in the Singapore business as well as in future growth in other locations outside the United States. The Company also intends to permanently reinvest its unrepatriated earnings from all other foreign subsidiaries. The cumulative amount of undistributed earnings of foreign subsidiaries was $116,426,000 at November 30, 2010. Because such earnings are expected to be reinvested indefinitely no deferred tax liability has been recognized with regard to the remittance of such earnings.

48

FINANCIAL SECTION

Any additional U.S. income tax on the unremitted foreign earnings, if repatriated, may be offset in whole or in part by foreign tax credits. The 2010 repatriation plan previously mentioned, which was an exception to the Company’s repatriation policy, was implemented at an unusually low tax rate and was intended to take advantage of certain tax laws that may unfavorably change in 2011.

A reconciliation of unrecognized tax benefits follows:

(In thousands) 2010 2009 2008

Unrecognized tax benefits at the beginning of the year $ 9,230 $ 7,416 $ 13,102 Increases for positions taken in current year 2,789 1,983 1,157 Increases for positions taken in prior years 173 1,137 658 Decreases for positions taken in prior years (45) (244) (6,557) Decreases for settlements with taxing authorities (50) (502) (145) Decreases for lapses in the applicable statute of limitations (645) (560) (799) Unrecognized tax benefits at the end of the year $11,452 $ 9,230 $ 7,416

At November 30, 2010, the total amount of gross unrecognized tax benefits, excluding interest, was $11,452,000. This amount is not reduced for offsetting benefits in other tax jurisdictions and for the benefit of future tax deductions that would arise as a result of settling such liabilities as recorded. Of this amount, $5,869,000 would reduce the Company’s income tax expense and effective tax rate, after giving effect to offsetting benefits from other tax jurisdictions and resulting future deductions. At November 30, 2009, the total amount of gross unrecognized tax benefits, excluding interest, was $9,230,000.

The Company anticipates that it is reasonably possible that unrecognized tax benefits may change within the succeeding 12 months as a result of the expiration of certain state and foreign statutes of limitations for examination and the settlement of certain state audits. The Company estimates that these events could reasonably result in a possible decrease in unrecognized tax benefits of $917,000.

The Company accrues interest and penalties related to unrecognized tax benefits as income tax expense. Accruals totaling $1,153,000 were recorded as a liability in the Company’s consolidated balance sheet at November 30, 2010, compared to $1,030,000 as of November 30, 2009.

NOTE 11 DEBT

Short-term borrowings consist of loans payable under bank credit lines. There were no short-term borrowings outstanding at November 30, 2010 and at November 30, 2009.

Domestically, as of November 30, 2010, the Company maintained a $100,000,000 revolving credit facility with six banks (the “Revolver”). At November 30, 2010, $17,212,000 of the Revolver was utilized for standby letters of credit; therefore, $82,788,000 was available. Under the Revolver, the Company may, at its option, borrow at floating interest rates (LIBOR plus a spread ranging from 2.75% to 3.75% based on the Company’s financial condition and performance) or utilize for letters of credit, at any time until August 2012, when all borrowings under the Revolver must be repaid and letters of credit cancelled.

Foreign subsidiaries also maintain unsecured revolving credit facilities and short-term facilities with banks. Foreign subsidiaries may borrow in various currencies, at interest rates based upon specified margins over money market rates. Existing foreign credit facilities permit short-term borrowings up to $12,400,000. At November 30, 2010, there were no borrowings under these facilities.

The Company intends for short-term borrowing, if any, under bank facilities utilized by the Company and its foreign subsidiaries to be refinanced on a long-term basis via the Revolver.

The Company’s lending agreements contain various restrictive covenants, including the requirement to maintain specified amounts of net worth and restrictions on cash dividends, borrowings, liens, investments, capital expenditures, guarantees, and financial covenants. The Company is required to maintain consolidated net worth of $375,500,000 plus 50% of net income and 75% of proceeds from any equity issued after November 30, 2008. The Company’s consolidated net worth exceeded the covenant amount by $142,417,000 as of November 30, 2010. The Company is required to maintain a consolidated leverage ratio of consolidated funded indebtedness to earnings before interest, taxes, depreciation and amortization (“EBITDA”) of no more than 2.50 times. At November 30, 2010, the Company maintained a consolidated leverage ratio of .58 times EBITDA. Lending agreements require that the Company maintain qualified consolidated tangible assets at least equal to the outstanding secured funded indebtedness. At November 30, 2010, qualifying tangible assets equaled 5.52 times funded indebtedness. Under the most restrictive fixed charge coverage ratio, the sum of EBITDA and rental expense less cash taxes must be at least 1.50 times the sum of interest expense, rental expense, dividends and scheduled funded debt payments. At November 30, 2010, the Company maintained such a fixed charge coverage ratio of 2.04 times. Under the most restrictive provisions of the Company’s lending agreements, $8,562,000 of retained earnings was not restricted, at November 30, 2010, as to the declaration of cash dividends or the repurchase of Company stock. In addition, the Company has received consents from its lenders to purchase up to $50.0 million of the Company’s Common Stock. At November 30, 2010, the Company was in compliance with all financial covenants.

The Revolver and the 4.25% term notes are collateralized by substantially all of the Company’s assets. The industrial revenue bonds are supported by standby letters of credit that are issued under the Revolver. The interest rate on the industrial development bonds is based on the Securities Industry and Financial Markets Association (“SIFMA”) index plus a spread of approximately .20%. Certain note agreements contain provisions regarding the Company’s ability to grant security interests or liens in association with other debt instruments. If the Company grants such a security interest or lien, then such notes will be collateralized equally and ratably as long as such other debt shall be collateralized.

Interest income and expense were as follows for the year ended November 30:

Estimated fair value of the Company’s debt is prepared in accordance with the FASB’s fair value disclosure requirements. These requirements establish an enhanced framework for measuring the fair value of financial instruments including a disclosure hierarchy based on the inputs used to measure fair value. The estimated fair value amounts were determined by the Company using available market information and appropriate valuation methodologies. Considerable judgment is required to develop the estimated fair value, thus the estimates provided herein are not necessarily indicative of the amounts that could be realized in a current market exchange.

As of November 30, 2010, the Company had outstanding grants under the following share-based compensation plans: 2001 Stock Incentive Plan (“2001 Plan”) - The 2001 Plan was terminated in 2004, except as to the outstanding stock options and restricted stock grants. Prior to termination, a total of 380,000 new shares of Common Stock were made available for awards to key employees and non-employee directors. Non-employee directors were granted options under the 2001 Plan to purchase the Company’s Common Stock at prices not less than 100% of market value on the date of grant. Such options vested in equal annual installments over four years. Such options terminate ten years from the date of grant. At November 30, 2010, there were 6,000 shares subject to such stock options. 2004 Stock Incentive Plan (“2004 Plan”) - The 2004 Plan serves as the successor to the 2001 Plan and supersedes that plan. A total of 525,000 new shares of Common Stock were made available for awards to key employees and non-employee directors and may include, but are not limited to, stock options and restricted stock grants. Non-employee directors were granted options under the 2004 Plan to purchase the Company’s Common Stock at prices not less than 100% of market value on the date of grant. Such options vest in equal annual installments over four years and terminate ten years from the date of grant. At November 30, 2010, there were 15,052 shares subject to such stock options. Key employees and non-employee directors were granted restricted stock under the 2004 Plan. Such restricted stock typically vests in equal annual installments over three years. During 2010, the Company granted 11,500 restricted shares to key employees with a fair value on the grant date of $781,000 and 10,800 restricted shares to non-employee directors with a fair value on the grant date of $684,000. During 2009, the Company granted 16,200 restricted shares to key employees with a fair value on the grant date of $806,000 and 12,000 restricted shares to non-employee directors with a fair value on the grant date of $575,000. In 2007, the Company agreed to provide to a key employee 18,000 shares of Common Stock to be granted and fully vested each February of 2008, 2009 and 2010. The fair value of those 54,000 shares on the date promised was $5,395,000. Additionally in 2007, the key employee received a grant of performance stock units, pursuant to which from 8,000 to 24,000 shares of the Company’s Common Stock could potentially be issued depending on the price of the Common Stock on the date the award vests, no later than November 30, 2010. In April 2010, the key employee was issued 8,000 shares in connection with the performance stock units. A lattice model was used with volatility rate of 38% and risk free rate of 4.04% in determining the fair value of the performance stock units. The volatility rate was calculated based on historical trading data with the anticipated life of 2.5 years. The risk-free rate was based on the contemporary yield curve between the two and three year rate. The fair value of the performance stock units on the grant date was $2,055,000, which was recognized ratably as stock compensation expense through March 31, 2010. In addition to the above, in 2001, non-employee directors were granted options to purchase the Company’s Common Stock at prices not less than 100% of market value on the date of grant. Such options vested in equal annual installments over four years and terminate ten years from the date of grant. At November 30, 2010, there were 2,000 shares subject to such stock options. The Company’s income before income taxes and equity in loss of affiliate for the year ended November 30, 2010 included compensation expense of $2,005,000, related to stock-based compensation arrangements, compared to $3,936,000 in 2009 and $6,113,000 in 2008. Tax benefit related to this expense was $782,000 in 2010, compared to $1,535,000 in 2009 and $2,384,000 in 2008. There were no capitalized share-based compensation costs for the three years ended November 30, 2010. Tax benefits and excess tax benefits resulting from the exercise of stock options are reflected as financing cash flows in the Company’s statements of cash flows. The Company recognized a tax deficiency of $693,000 for the year ended November 30, 2010 and excess tax benefits totaled $831,000 and $1,330,000 in 2009 and 2008, respectively.

The aggregate intrinsic value in the table above represents the total pretax intrinsic value, which is the difference between the closing price of the Company’s Common Stock on the last trading day of 2010 and the exercise price times the number of shares that would have been received by the option holders if they exercised their options on November 30, 2010. This amount will change based on the fair market value of the Company’s Common Stock. The aggregate intrinsic value of stock options exercised in 2010 was $500,000, and $2,414,000 in 2008. No stock options were exercised in 2009.

As of November 30, 2010, there was $1,007,000 of total unrecognized compensation cost related to stock-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of three years.

In 2010, 2009, and 2008, respectively, 22,300, 28,200, and 26,200 shares of restricted stock were granted. The weighted-average, grant-date fair value per share of such stock was $65.67, $48.98, and $101.18, respectively. The fair value of restricted stock which vested and stock promised in 2007 which was granted in 2010, 2009, and 2008 was $3,381,000, $2,678,000, and $5,844,000, respectively. In 2010, 2009 and 2008, 6,000, 5,655 and 1,667 shares of restricted stock were forfeited, with a fair value of $286,000, $432,000 and $91,000, respectively.

Net cash proceeds from stock options exercised were $372,000 in 2010 and $420,000 in 2008. No stock options were exercised in 2009. The Company’s policy is to issue shares from its authorized shares upon the exercise of stock options.

NOTE 15 COMMITMENTS AND CONTINGENCIES

In 2004, Sable Offshore Energy Inc. (“Sable”), as agent for certain owners of the Sable Offshore Energy Project, brought an action against various coatings suppliers and application contractors, including the Company and its subsidiary, Ameron B.V., in the Supreme Court of Nova Scotia, Canada. Sable seeks damages allegedly sustained by it resulting from performance problems with several coating systems used on the Sable Offshore Energy Project, including coatings products furnished by the Company and Ameron B.V. All of the co-defendants, other than the Company, Ameron B.V. and an unaffiliated licensee of the Company, have since settled. Sable’s originating notice and statement of claim alleged a claim for damages in an unspecified amount. Sable later alleged that its claim for damages against all defendants was approximately 440,000,000 Canadian dollars. More recently, however, Sable sent the Company a revised claim which included an alternative method for calculating damages. Although Sable did not specify an aggregate claim amount under its alternative method, that method if adopted would appear to substantially reduce the amount of damages. The Company contests any claim amount and is vigorously defending itself on the merits in this action. This matter is in discovery, and no trial date has yet been established. Based upon the information available at this time, the Company is not able to estimate the possible range of loss with respect to this case.

In 2004, BP America Production Company (“BP America”) brought an action against the Company in the 24th Judicial District Court, Parish of Jefferson, Louisiana in connection with fiberglass pipe sold by the Company for installation in four offshore platforms constructed for BP America. The plaintiff seeks damages allegedly sustained by it resulting from claimed defects in such pipe. BP America’s petition as filed alleged a claim against the Company for rescission, products liability, negligence, breach of contract and warranty and for damages in an amount of not less than $20,000,000; but BP America has since reduced its claim to $12,900,000. The Company contests this amount. This matter is in discovery, and no trial date has yet been established. The Company intends to vigorously defend itself in this action. Based upon the information available to it at this time, the Company is not able to estimate the possible range of loss with respect to this case.

In 2006, the Cawelo, California Water District (“Cawelo”) brought an action against the Company in the Superior Court, Kern County, California in connection with concrete pipe sold by the Company in 1995 for a wastewater recovery pipeline. Cawelo seeks damages allegedly sustained by it resulting from the failure of such pipe in 2004. Cawelo’s petition as filed alleged a claim against the Company for products liability, negligence, breach of express warranty and breach of written contract and for damages in an amount of not less than $8,000,000, an amount which the Company contested. On December 3, 2010, the Company settled this case subject to court approval for a net payment of $100,000 by the Company. On December 27, 2010, the Court issued an order finding the settlement by the Company to be in good faith and dismissing a cross-complaint against the Company by a surety of a non-settling defendant. The order remains subject to possible appeal. The terms of the settlement will not have a material effect on the Company’s financial condition or results of operations.

In August 2010, Petroleum Polymer Company LLC (“PPC”) brought an action against Ameron (Pte) Ltd. (“Ameron Pte”), an indirect subsidiary of the Company, in the Primary Court of Oman. The complaint alleged that Ameron Pte breached the terms of a purchase agreement for its supply of fiberglass pipe to PPC for use in an oil extraction project in Oman. PPC’s primary allegation is that a component supplied by Ameron Pte failed during testing, resulting in a failure of the pipe system. PPC asserted damages totaling approximately $20,000,000, including alleged claims for the cost of replacing damaged pipe, recovery of penalties incurred due to the resulting delay in the project, and lost future opportunities. Ameron Pte contests any claim amount and intends to vigorously defend itself in this action. Based upon the information available to it at this time, the Company is able to neither estimate the possible range of loss with respect to this case nor the timing of substantive judicial proceedings.

The Company is a defendant in a number of asbestos-related personal injury lawsuits. These cases generally seek unspecified damages for asbestos-related diseases based on alleged exposure to products previously manufactured by the Company and others. As of November 30, 2010, the Company was a defendant in 14 asbestos-related cases, compared to 20 cases as of November 30, 2009. During the year ended November 30, 2010, there were ten new asbestos-related cases, 11 dismissed cases, five settled cases and no judgments. The Company incurred net expenses of $98,000, $272,000 and $234,000, and recovered $28,000, $138,000 and $151,000, during the years ended November 30, 2010, 2009 and 2008, respectively. Based upon the information available to it at this time, the Company is not able to estimate the possible range of loss with respect to these cases.

In December 2008, the Company received from the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) a Requirement to Furnish Information regarding transactions involving Iran. With the assistance of outside counsel, the Company conducted an internal inquiry and continues to cooperate fully with OFAC on this matter. Based upon the information available to it at this time, the Company is not able to predict the outcome of this matter. If the Company violated governmental regulations, material fines and penalties could be imposed.

The Company is subject to federal, state and local laws and regulations concerning the environment and is currently participating in administrative proceedings at several sites under these laws. While the Company finds it difficult to estimate with any certainty the total cost of remediation at the several sites, on the basis of currently available information and reserves provided, the Company believes that the outcome of such environmental regulatory proceedings will not have a material effect on the Company’s financial position, cash flows, or results of operations.

In addition, certain other claims, suits and complaints that arise in the ordinary course of business have been filed or are pending against the Company. Management believes that these matters are either adequately reserved, covered by insurance, or would not have a material effect on the Company’s financial position, cash flows or results of operations if disposed of unfavorably.

NOTE 16 EMPLOYEE BENEFIT PLANS

The Company has a qualified, defined benefit, noncontributory pension plan for certain U.S. employees. The Company’s subsidiary in the Netherlands provides defined retirement benefits to eligible employees. The Company also provides health and life insurance to a limited number of eligible retirees and eligible survivors of retirees.

The Company’s defined benefit pension and other postretirement benefit costs and obligations are dependent on assumptions used by actuaries in calculating such amounts. These assumptions, which are reviewed annually, include discount rates, long-term expected rates of return on plan assets and expected rates of increase in compensation and health care costs. Assumed discount rates, based on market interest rates on long-term fixed income debt securities of highly-rated corporations, are used to calculate the present value of benefit payments which are projected to be made in the future, including projections of increases in employees’ annual compensation and health care costs. A decrease in the discount rate would increase the Company’s obligation and expense. The long-term expected rate of return on plan assets is based principally on prior performance and future expectations for various types of investments as well as the expected long-term allocation of assets. Changes in the allocation of plan assets would impact the expected rate of return. The expected rate of increase in compensation is based upon movements in inflation rates as reflected by market interest rates. Benefits paid to participants are based upon age, years of credited service and average compensation or negotiated benefit rates.

Assets of the Company’s U.S. defined benefit plan are invested in a directed trust. Assets in the trust are invested in domestic and foreign equity securities of corporations (including $5,664,000 of the Company’s Common Stock at November 30, 2010), U.S. government obligations, derivative securities, corporate bonds and money market funds. The subsidiary in the Netherlands contracts with third-party insurance companies to pay benefits to retirees.

The above table includes net periodic cost for 12 months for all periods. Additionally in 2009, the Company recorded to retained earnings two months of net periodic cost of $1,631,000 ($993,000 net of tax) relating to the change in measurement date for the Company’s U.S. defined benefit plan.

The following table provides the weighted-average assumptions used to compute the actuarial present value of projected benefit obligations: U.S. Pension Benefits Non-U.S. Pension Benefits 2010 2009 2008 2010 2009 2008 Weighted-average discount rate 5.30% 5.70% 7.29% 4.75% 5.20% 6.70% Rate of increase in compensation levels 3.00% 3.50% 4.25% 2.25% 2.25% 2.25%

The respective discount rates were determined by projecting the plan’s expected future benefit payments as defined for the projected benefit obligation, discounting those expected payments using a theoretical zero-coupon spot yield curve derived from high-quality corporate bonds currently available as of the plan measurement date, and solving for the single equivalent discount rate that resulted in the same projected benefit obligation.

The respective expected long-term rates of return on plan assets were determined based on historical and expected future returns of the various asset classes in which the Company expected the pension funds to be invested. The expected returns by asset class were as follows, as of November 30, 2010: U.S. Pension Non-U.S. Pension Benefits Benefits Equity securities 10% 7% Debt securities 5% 4% Real estate — 7% Other — 3%

The Company’s investment policy includes a mandate to diversify assets by investing in a variety of asset classes. At November 30, 2010, the plan’s assets were invested in a variety of funds representing standard equity and debt security classes. No significant changes in the asset allocations are expected during the upcoming year.

The following table shows the Company’s target allocation for the U.S. defined benefit pension plan, along with the actual allocations for the U.S. and non-U.S. plans, as of November 30: U.S. Pension Benefits Non-U.S. Pension Benefits Target 2010 2009 2010 2009 Domestic equities 65% 61% 61% 7% 8% International equities 10% 10% 11% 9% 10% Fixed-income securities 25% 29% 28% 84% 82% Total 100% 100% 100% 100% 100%

Approximately 9% of the Company’s employees are covered by union-sponsored, collectively-bargained, multi-employer pension plans. Related to these plans, the Company contributed and charged to expense $1,500,000, $800,000, and $1,300,000 in 2010, 2009, and 2008, respectively. These contributions are determined in accordance with the provisions of negotiated labor contracts and generally are based on the number of hours worked. The Company has no intention of withdrawing from any of these plans, nor is there any intention to terminate such plans.

The Company provides to certain employees a savings plan under Section 401(k) of the U.S. Internal Revenue Code. The savings plan allows for deferral of income through contributions to the plan, with certain restrictions. Company matching contributions are in the form of cash. In 2010, 2009, and 2008, the Company recorded expense for matching contributions of $517,000, $488,000, and $296,000, respectively.

The effect of a one-percentage-point change in the assumed health care cost trend would have changed the amounts of the benefit obligation and the sum of the service cost and interest cost components of postretirement benefit expense for 2010, as follows: (In thousands) 1% Increase 1% Decrease Effect on total of service and interest cost components of net periodic expense $ 17 $ (14) Effect on postretirement benefit obligation 150 (133)

The Company provides life insurance to eligible executives with life insurance protection equal to three times base salary. Upon retirement, the executive is provided with life insurance protection equal to final base salary. There were no expenses related to this plan in 2010, 2009 or 2008.

The Company has severance agreements with certain key employees that could provide benefits upon termination of up to three times total annual compensation of such employees, plus a pro rata portion of their current year’s annual bonus.

Investments

All investments are stated at fair value or amounts that closely approximate fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).

The Company utilizes market data or assumptions that the Company believes market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable.

The Company primarily applies the income and market approach for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company is able to classify fair value balances based on the observability of those inputs.

A fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Level 2 measurements utilize observable inputs in markets other than active markets.

Following is a description of the valuation methodologies used for pension assets measured at fair value. There have been no changes in the methodologies used at November 30, 2010 and 2009.

Common stocks: Valued at the closing price reported on the active market on which the individual securities are traded. Mutual funds: Valued at the net asset value (“NAV”) of shares held by the plan at the valuation date.

Common/collective trusts: Valued by the sponsor of the trust based on aggregate value of all assets in the collective trust at the valuation date. Unit value of a fund is determined by dividing net assets at fair value by the fund’s units outstanding at the valuation date.

58

FINANCIAL SECTION

Insurance contracts: Insurance contracts primarily include the contracts used by the non-U.S. Pension Plan and other postretirement benefit plan to pay benefits. These contracts are valued by the counterparty insurance companies. Insurance contracts also consist of one participating insurance contract held in the U.S. Pension Plan that is valued by discounting the related cash flows (i.e., expected dividends) as determined by the plan’s actuary. The plan has no future liability related to the contract, and the total value of the contract in excess of the value of the expected dividends is excluded from the plan’s assets.

The preceding methods described may produce fair values that may not be indicative of net realizable values or reflective of future fair value. Furthermore, although the Company believes the valuation methods used by the plan’s trustees are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the valuation date.

NOTE 18 SEGMENT INFORMATION

The Company has determined it has four operating and three reportable segments: Fiberglass-Composite Pipe, Water Transmission and Infrastructure Products. The Fiberglass-Composite Pipe Group manufactures and markets filament-wound and molded composite fiberglass pipe, tubing, fittings and well screens. The Water Transmission Group manufactures and supplies concrete and steel pressure pipe, concrete non-pressure pipe, protective linings for pipe, and fabricated products including wind towers. The Infrastructure Products Group consists of two operating segments, the Pole Products and Hawaii Divisions, and manufactures and sells ready-mix concrete, sand and aggregates, concrete pipe and culverts, and concrete and steel lighting and traffic poles. In the prior periods, the Company included a fourth reportable segment, Performance Coatings & Finishes, which was sold August 1, 2006. The results from this segment are reported as discontinued operations for all reporting periods. Each of these segments has a dedicated management team and is managed separately, primarily because of differences in products. TAMCO, the Company’s equity method investment which was sold in October of 2010, is not included in any of these segments. The Company’s Chief Operating Decision Maker is the Chief Executive Officer who primarily reviews sales and income before interest, income taxes and equity in earnings of affiliate for each operating segment in making decisions about allocating resources and assessing performance. The Company allocates certain selling, general and administrative expenses to operating segments utilizing assumptions believed to be appropriate in the circumstances. Costs of shared services (e.g., costs of Company-wide insurance programs or benefit plans) are allocated to the operating segments based on revenue, wages or net assets employed. Other items not related to current operations or of an unusual nature, such as adjustments to reflect inventory balances of certain steel inventories under the LIFO method, certain unusual legal costs and expenses, interest expense and income taxes, are not allocated to the reportable segments.

The markets served by the Fiberglass-Composite Pipe Group are worldwide in scope. The Water Transmission Group serves primarily the western U.S. The Infrastructure Products Group’s quarry and ready-mix business operates exclusively in Hawaii, and poles are sold throughout the U.S. Sales to any individual customer did not exceed 10% of consolidated sales in 2010 or in 2008. In 2009, Siemens Power Generation, Inc. purchased $66,400,000 of wind towers from the Company, which was approximately 12% of the Company’s total consolidated sales and almost all of the Company’s wind tower sales.

FINANCIAL SECTION

Cash Equivalents

Cash equivalents are comprised of money market funds and time deposits. The net carrying amount of cash equivalents approximates fair value due to the short-term nature of these instruments.

Derivatives

The Company and its subsidiaries complete transactions in currencies other than their functional currencies. The Company’s primary objective with respect to currency risk is to reduce net income volatility that would otherwise occur due to exchange-rate fluctuations. In order to minimize the risk of gain or loss due to exchange rates, the Company may from time to time use foreign currency derivatives. As of November 30, 2010, the Company held four foreign currency forward contracts comprised of two foreign currency contracts aggregating in the amount of $11,000,000 U.S. dollars, hedging Singapore dollars, one contract in the amount of $1,250,000 Singapore dollars, hedging Malaysian Ringgit, and one contract in the amount of $388,000 U.S. dollars, hedging Euros. As of November 30, 2009, the Company held one foreign currency forward contract aggregating $6,000,000 U.S. dollars, hedging Singapore dollars, and two contracts aggregating $660,000 U.S. dollars, hedging Euros, compared to holding one foreign currency forward contract aggregating $500,000, hedging U.S. dollars to Singapore dollars, and two contracts aggregating $769,000, hedging U.S. dollars to Euros at November 30, 2008. Such instruments had a combined fair value loss of $16,000 as of November 30, 2010 and 2009, based on quotations from financial institutions. Derivatives are recorded as receivables and or liabilities on the balance sheet, and the related gains and losses are recognized as other income, net on the income statement.

MANAGEMENT’S REPORT

The Audit Committee of the Board of Directors is composed of four directors who are not officers or employees of the Company. They meet periodically with management, PricewaterhouseCoopers LLP and the internal auditors to review the audit scope and results, discuss internal controls and financial reporting subjects, and review management actions on these matters. PricewaterhouseCoopers LLP and the internal auditors have full and free access to the members of the Audit Committee.

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

Management established disclosure controls and procedures to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the officers who certify the Company’s financial reports and to other members of senior management and the Board of Directors.

The Company carried out an evaluation, under the supervision and with the participation of the Company’s Management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of November 30, 2010 pursuant to Exchange Act Rule 13a-14. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) are effective. Disclosure controls and procedures are the controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports filed or submitted by it under the Securities Exchange Act of 1934, as amended (Exchange Act), is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in its Exchange Act reports is accumulated and communicated to the issuer’s management, including its principal executive and financial officers, as appropriate to allow timely decisions regarding required disclosure. No changes were made in the Company’s internal control over financial reporting during the fiscal quarter ended November 30, 2010 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f) and 15d-15(f). Under the supervision and with the participation of Management, including the principal executive officer and principal financial officer, Management conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on Management’s evaluation under the framework in Internal Control - Integrated Framework, Management concluded that internal control over financial reporting was effective as of November 30, 2010. The effectiveness of the Company’s internal control over financial reporting as of November 30, 2010 was audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Ameron International Corporation

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, of stockholders’ equity, of comprehensive income, and of cash flows present fairly, in all material respects, the financial position of Ameron International Corporation and its subsidiaries at November 30, 2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended November 30, 2010 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of November 30, 2010, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 16 to the consolidated financial statements, the Company changed the manner in which it accounts for defined benefit pension and other postretirement benefit plans in 2009.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Summary We Urge Stockholders to Support the Current Board and Reject Barington and James Mitarotonda The type of Board change recommended by Barington would be counterproductive: Board and Management are constantly evaluating businesses, markets, and governance Ameron is a multinational manufacturer of highly-engineered products and materials for chemical, industrial, energy and infrastructure markets Compound total return to Ameron’s stockholders from November 30, 1993 to January 31, 2011 has totaled approximately 11% per year Management constantly adjusts Ameron’s portfolio of business to create and maximize stockholder value, better position the Company for future success, and increase its competitiveness Ameron has been repositioning itself over the years Enhancing stockholder value and consistently generating quality earnings over time can only result from developing the proper business strategies and effectively executing those plans. Delivering on that philosophy has been our trademark over the years Ameron is led by a dedicated CEO and senior management team, overseen by an active and engaged Board, with a multi-year record of creating and delivering stockholder value Board has been responsive to stockholders and updated both corporate governance and compensation practices Conducting an orderly succession process and have retained Korn Ferry to conduct a search for a new CEO We do not believe James Mitarotonda is right for Ameron and its stockholders James Mitarotonda and Barington offer no new ideas for Ameron We question Mitarotonda’s ethics and integrity, do not think he has the experience or expertise required to be on the Board of a complex, global company such as Ameron 3

Deployment of fiberglass distribution poles for utilities

Water Transmission

Evaluating major water projects in the U.S. and Mexico

Development of proprietary pressure-cast steel pipe to reduce raw material costs and ease of installation

Pole Products

Building new steel pole plant in Oklahoma for the national transportation infrastructure market

21 AMERON INTERNATIONAL

Overview of Ameron - Strategic Rationale

Over time, Ameron was repositioned to focus on businesses and markets where Ameron has leadership position

Sold Coatings due to lack of market leadership, competing against larger, global companies and attractive valuation from buyer

Sold TAMCO due to increased competition from larger focused steel companies and attractive valuation from buyer

Maintain businesses with growth potential and leadership position by Ameron

Company’s Fiberglass Composite Pipe Group driven by increasing demand for energy; Ameron has the widest range of products and strength in most profitable marine and offshore segment due to technical capabilities and state-of-the-art manufacturing

Water Transmission Group’s water pipe business is driven by demographics and scarce water resources; Ameron has leadership position in western U.S. Current down cycle lasting longer than experts predicted; however, business can be quite profitable (2005 segment income of $26 million on sales of $193 million)

22 AMERON INTERNATIONAL

Overview of Ameron - Strategic Rationale (cont.)

Water Transmission Group’s wind tower business driven by demand for renewable energy, Ameron is well placed to serve West with only plant in California. Currently unprofitable due to depressed market conditions, but had a backlog of over $90 million at end of 2008. Plant has annual capacity to add $120 million of sales

Hawaii Division is largest provider of aggregates and ready-mix concrete in Hawaii. Pole Products Division is largest supplier of concrete lighting poles in U.S. Infrastructure Products Group depressed due to construction downturn, but significant opportunities when cycle turns (2006 segment income of $31 million on sales of $198 million)

Although we have reviewed each business internally, with our Board and with our financial advisors, the lack of current profitability is not a justification for divestiture because our market position is strong and good potential for improvement

All of Ameron’s current businesses have potential for significant growth and should be retained

Ameron Performance

24 AMERON INTERNATIONAL

Ameron Performance — Overview

Ameron earnings per share has grown at a compound annual rate of 12% from 1994 through 2008, when global recession began

Compound total return to Ameron’s stockholders from November 30, 1993 through January 31, 2011 has totaled approximately 11% per year, outperforming market indices

Ameron’s portfolio of businesses is constantly managed to create and maximize stockholder value, better position the Company for future success, and increase its competitiveness

As part of this effort, Management has positioned the core business segments, Fiberglass-Composite Pipe Group, Water

Transmission Group and Infrastructure Products Group, to capture market share and to grow when Ameron’s end markets recover

James S. Marlen

As chief executive of the Company for 17 years, and with a record as an operating manager and an engineer prior to joining the Company, Marlen brings a unique depth of understanding of all aspects of the Company’s operations

Marlen brought to the Company 28 years of U.S. and international experience in diversified businesses

These experiences allow him to provide unique insights, strategic direction and critical thinking to the Board and management

He also brings deep legal experience that helps the Board gauge and manage risks. All of these factors led to the conclusion that Davenport should continue to serve as a director in light of the Company’s business and structure

As a member of the Audit Committee, Davenport is also financially literate and has accounting or related financial management expertise as required by the NYSE’s corporate governance standards

Barington’s Proxy Fight — James Mitarotonda’s Background

Mitarotonda started Barington Capital in 1991 as an investment bank targeting small businesses, after beginning his brokerage career at DH Blair; a firm that was subsequently served with a criminal indictment

Mitarotonda was forced to sell his brokerage operations and investment banking division in 1999. According to one media report, many of “Barington’s problems were self inflicted”1

Mitarotonda launched his activist hedge fund in 2000 and targeted microcap, retail, shoe, investment management and Internet music companies. Indeed, most of Mitarotonda’s director and executive experience has been with these same types of companies

Mitarotonda not qualified to lead Ameron — a complex, international, heavy-manufacturing company

1 A story in the WallStreetReporter.com in 2003 titled, “Corporate America just doesn’t understand Jim Mitarotonda” claims, “The rapid rise and fall of Barington’s investment banking operation once again highlighted Mitarotonda’s skill for identifying a profitable niche but raises questions about his vision for recognizing the evolving needs of clients and a shifting competitive landscape.”

Barington’s Proxy Fight — Concerns About Mitarotonda

Thorough evaluation of Mitarotonda began in 2010: He did not then and does not now meet our standards and requirements for Ameron Directors

Mitarotonda lacks the high degree of integrity and ethics expected of Ameron Directors

Breaches of fiduciary duties, unauthorized trading, failure to supervise

Investors have sued Barington for breaches of fiduciary duties numerous times—and won

Payless ShoeSource made a similar determination in his last proxy fight

Barington has a history of manipulating companies for its own gain and profiting as they fail

The Bottom Line: Director selection process at Ameron is focused on judgment, integrity, ethics and performance. Mitarotonda does not meet our standards of excellence

Barington’s Proxy Fight — Concerns About Mitarotonda (cont.)

Max Lukens was initially on the Barington slate of directors

Mitarotonda had all references to Lukens, the Chairman of Pep Boys, where Mitarotonda serves as a director, removed from Barington’s preliminary proxy statement

Lukens apparently did not find out about that until we contacted him to find out why

Mitarotonda does not bring meaningful experience or a track record of success

We believe Mitarotonda is interested only in short-term personal gains, with no regard for creating long-term value for stockholders

Barington offers no real plan for improvement, and proposes to replace Directors who provide critical, relevant business perspective and experience

The Bottom Line: Director selection process at Ameron is focused on judgment, integrity, ethics and performance. Mitarotonda does not meet our standards of excellence

Barington’s Proxy Fight — Mitarotonda and Barington’s Approach to Corporate Governance

Ameron - Assessing and Improving Corporate Governance Practices

The Ameron Board is continually assessing corporate governance practices and has adopted several significant changes.

The Ameron Board has a demonstrated track record of closely examining suggestions from stockholders, ISS and other advisory groups

Barington’s approach to corporate governance

Barington claims to take a “pragmatic” approach to corporate governance, however it appears Mitarotonda takes more of a “Do as I say, not as I do” approach

Barington’s Proxy Fight — Mitarotonda and Barington’s Approach to Corporate Governance (cont.)

Mitarotonda’s “Do as I say, not as I do” approach to corporate governance

A. Schulman

Although Mitarotonda (joined board in 2005) and his nominees have a significant presence on the board and compensation committee for numerous years, and despite the fact that

Mitarotonda used compensation concerns as part of his activist campaign at A. Schulman, the compensation committee has actually received worse grades since Mitarotonda joined the committee;

Glass Lewis has assigned the A. Schulman compensation committee a grade of;

- D in 2008,

- D in 2009,

- F in December 2010

In December of 2010, Glass Lewis also recommended stockholders of A. Schulman withhold their votes on Mitarotonda (and others members of the compensation committee) and claimed Mitarotonda and the committee were, “deficient in linking pay with performance.” And.. “It appears to us members of this committee have not effectively served stockholders in this regard”

ISS expresses “Medium Concern” with A. Schulman’s Compensation Practices

A. Schulman has not adopted majority voting in their director elections as of December 2010 annual meeting

A. Schulman has some supermajority voting restrictions

A. Schulman has a more restrictive advanced notice bylaw for director nominations and other business than Ameron does

Barington’s Proxy Fight — Mitarotonda and

Barington’s Approach to Corporate Governance (cont.)

Mitarotonda’s “Do as I say, not as I do” approach to corporate governance

The Pep Boys — Manny, Moe and Jack

Although Mitarotonda has had at least two of his nominees on the compensation committee since 2006, and despite the fact that Mitarotonda sits on the compensation committee now, the committee has received poor grades from Glass Lewis and ISS

Glass Lewis has assigned the Pep Boys compensation committee four consecutive D grades:

- D in 2007,

- D in 2008,

- D in 2009,

- D in 2010

ISS currently expresses Medium Concern on Pep Boys compensation practices

Pep Boys received a stockholder proposal in 2010 (the board opposed) to reduce the remaining supermajority provisions at Pep Boys. The proposal received a majority support of 56% of the voted shares

Will Mitarotonda be responsive to the stockholder vote he does not agree with?

Barington’s Proxy Fight — Mitarotonda’s Performance

Mitarotonda likes to highlight his experiences at A. Schulman, Griffon and Pep Boys as being relevant to Ameron stockholders because they are a different class of companies to Mitarotonda’s typical investments. What he fails to tell you is that stockholders of these companies have suffered underperformance versus their peers and relevant indices since Mitarotonda joined the Board

According to Barington’s June 30, 2007 13F filing, equity assets under management were $517 million

As of 12/21/10 Barington’s equity assets under management are less than $100 million (Barington did not file a 13F). This is a decline of approximately 80% since June 2007

Stockholders should ask, if Barington’s investors believed in Mitarotonda’s ability to create stockholder value, why has money been pulled out?

Barington and Mitarotonda Would Not Bring a Successful Record to Ameron
