Overview

We are a global designer and manufacturer of custom-engineered ejectors, vacuum systems, condensers, liquid ring pump packages and heat exchangers to the refining and petrochemical industries, and a nuclear code accredited supplier of components and raw materials to the nuclear power generating market. Our equipment is used in critical applications in the petrochemical, oil refining and electric power generation industries, including nuclear, cogeneration and geothermal plants. Our equipment can also be found in alternative energy, including ethanol, biodiesel and coal and gas-to-liquids, as well as other diverse applications, such as metal refining, pulp and paper processing, shipbuilding, (the nuclear propulsion program of the U.S. Navy), water heating, refrigeration, desalination, soap manufacturing, food processing, pharmaceuticals, and heating, ventilating and air conditioning.

Our corporate offices are located in Batavia, New York and we have production facilities in both Batavia, New York and at our wholly-owned subsidiary, Energy Steel & Supply Co., located in Lapeer, Michigan. We also have a wholly-owned foreign subsidiary, Graham Vacuum and Heat Transfer Technology (Suzhou) Co., Ltd., located in Suzhou, China, which supports sales orders from China and provides engineering support and supervision of subcontracted fabrication.

On December 14, 2010, we acquired Energy Steel to advance our strategy to diversify our products and broaden our offerings to the energy industry. This transaction was accounted for under the acquisition method of accounting. Accordingly, the results of Energy Steel were included in our consolidated financial statements and comparisons to our prior fiscal year will be enhanced by the inclusion of Energy Steel in this fiscal year's results.

Fiscal 2013 and the Near-Term Market Conditions

During fiscal 2012, bidding activity remained active. We believe the business environment is continuing to improve and that our customers are more inclined to procure the equipment needed for their projects. This supports our belief that our oil refining, petrochemical and related markets are in the early stages of a business recovery. While there continues to be uncertainty as to whether a sustained global economic recovery is occurring, we believe current signs (such as order activity during our fourth quarter of fiscal 2012) continue to be more positive than in the past few years.

Near-term demand trends that we believe are affecting our customers' investments include:

• As the world recovers from the global recession, many emerging economies continue to have relatively strong economic growth. This expansion is driving growing energy requirements and the need for more refined petroleum products. Although uncertainty in the capital and sovereign debt markets continues, there has been some improved access to capital, which has resulted in the release of certain previously stalled projects.

• The expansion of the economies of oil producing Middle Eastern countries, their desire to extract greater value from their oil and gas resources, and the continued global growth in demand for oil and refined products has renewed investment activity in that region. We do not believe that the ongoing political unrest in the Middle East has impacted our business. Moreover, the planned timeline of refinery projects in the major Middle Eastern countries is encouraging.

• Asian countries, specifically China and India, are experiencing renewed demand for refined petroleum products such as gasoline. This renewed demand is driving increased investment in petrochemical and

• South America, specifically Brazil, Venezuela and Colombia, is seeing increased refining and petrochemical investments that are driven by their expanding economies and increased local demand for gasoline and other products that are made from oil as the feedstock.

• The U.S. refining market has recently exhibited improvement, including demand in orders of short cycle and spare parts. Historically, these types of orders have suggested a recovery, as delayed spending is released. We expect that the U.S. refining markets will not return to the levels experienced during the last up cycle, but that such markets will improve compared with its levels over the past few years. We also expect that the U.S. refining markets will continue to be an important aspect of our business.

• We are beginning to see renewed signs of planned investments in the U.S. to convert greater percentages of crude oil to transportation fuels, such as revamping distillation columns to extract residual higher-value components from the low-value waste stream. We are also seeing renewed investment to expand the flexibility of facilities to allow them to utilize multiple feed stocks.

• Investments, including foreign investments, in North American oil sands projects have recently increased, especially for extraction projects in Alberta. Such investments suggest that downstream spending involving our equipment might increase in the next one to three years.

• The recent dramatic change in natural gas costs in the U.S. has led to a revival in the U.S. petrochemical market and a recent interest toward potential major investment. There are numerous projects in planning or initial engineering phases for the construction of new petrochemical producing facilities, including ethylene, ammonia and urea facilities. We historically have had strong market share within these facilities. Proposed ethylene capacity expansion and re-opening of mothballed facilities, in the U.S., as well as downstream products, are being discussed by petrochemical producers for the first time in well over a decade. Lower natural gas costs is a relatively recent phenomena, having occurred over the past three years and is driven by technology advancements in drilling, creating a significant increase in supply. This has made the U.S. production of raw material for ethylene, ethane (which is a side product of natural gas production) globally competitive with naphtha (the alternative feedstock for ethylene used in most of the world). We believe investment in U.S. petrochemical markets could be significant.

• Although investment in new nuclear power capacity in the U.S. and internationally may become subject to increased uncertainty due to political and social pressures, which were augmented by the tragic earthquake and tsunami that occurred in Japan in March 2011. The need for additional safety and back up redundancies at the 104 existing domestic nuclear plants could increase demand for Energy Steel's products in the near-term.

• Investments in existing U.S. nuclear plants to extend their operating life and add incremental capacity are expected to continue.

• Investment in new U.S. nuclear reactor projects planned for the Summer (South Carolina) and Vogtle (Georgia) facilities suggest continued growth in the domestic nuclear market, although such growth may be slowed by the perceptions related to the Fukajima accident in Japan.

We expect that the consequences of these near-term trends, and specifically projected expansion in petrochemical and oil refining that will most likely occur outside of North America, primarily in the growing Asian and South American markets, will result in more pressure on our pricing and gross margins, as these markets historically provided lower margins than North American refining markets. A counter to margin pressure from international markets may come from investments in new petrochemical capacity built in North America and the timing of such investments.

Because of continued global economic and financial uncertainty and the risk associated with growth in emerging economies, we also expect that we will have continued volatility in our order pattern. We continue to

expect our new order levels to remain volatile, resulting in both strong and weak quarters. As the chart below indicates, quarterly orders can vary significantly.

We believe that looking at our order level in any one quarter does not provide an accurate indication of our future expectations or performance. Rather, we believe that looking at our orders and backlog over a one to two year period provides a better measure of our business. In the near future we expect to see smaller value projects than what we had seen during the last expansion cycle. This will require more orders for us to achieve a similar revenue level and will adversely impact our ability to realize margin gains through volume leverage. Our quarterly order levels for fiscal 2012, fiscal 2011 and fiscal 2010, respectively, are set forth in the table below.

Mix Shift: Expected Stronger International Growth in Refining and Chemical Processing with Domestic Growth in Nuclear Power and U.S. Navy Projects

We expect growth in the refining and chemical processing markets to be driven by emerging markets. We have also expanded our addressable markets through the acquisition of Energy Steel and our focus on U.S. Navy nuclear propulsion projects. We believe our revenue opportunities during the near term will be equivalent between the domestic and international markets.

Over the long-term, we expect our customers' markets to regain their strength and, while remaining cyclical, continue to grow. We believe the long-term trends remain strong and that the drivers of future growth include:

Long-term Demand Trends

• Global consumption of crude oil is estimated to expand significantly over the next two decades, primarily in emerging markets. This is expected to offset estimated flat to slightly declining demand in North America and Europe. In addition, an increased trend toward export supply of finished product from the Middle East to North America and Europe.

• Global oil refining capacity is projected to increase, and is expected to be addressed through new facilities, refinery upgrades, revamps and expansions.

• Increased demand is expected for power, refinery and petrochemical products, stimulated by an expanding middle class in Asia and the Middle East.

• Increased development of geothermal electrical power plants in certain regions is expected to address projected growth in demand for electrical power.

• More refineries are expected to convert their facilities to use heavier, more readily available and lower cost crude oil as a feedstock.

• Lower costs are expected to drive increased domestic use of natural gas in the U.S., as well as, the ability to export liquefied natural gas to serve other regions, since natural gas in the U.S. is globally competitive with oil.

• Increased focus on safety and redundancy is anticipated in existing nuclear power facilities.

• Long-term increased project development of international nuclear facilities is expected, despite the recent tragedy in Japan, (including in the U.S.).

• Construction of new petrochemical plants in the Middle East to meet local demand.

• An expansion of the petrochemical market in the U.S., given the plentiful supply and globally competitive price of natural gas.

• Increased investments in new power generation projects are expected in Asia and South America to meet projected consumer demand increases.

• Long-term growth potential is believed to exist in alternative energy markets, such as geothermal, coal-to-liquids, gas-to-liquids and other emerging technologies, such as biodiesel, and waste-to-energy.

• Shale gas development and the resulting availability of affordable natural gas as feedstock to U.S.-based chemical/petrochemical facilities is expected to lead to renewed investment in chemical/petrochemical facilities in the U.S.

We believe that all of the above factors offer us long-term growth opportunities to meet our customers' expected capital project needs. In addition, we believe we can continue to grow our less cyclical smaller product lines and aftermarket businesses.

Our domestic sales as a percentage of aggregate product sales was 63% in our fiscal year ended March 31, 2009. As the U.S. market weakened, relative to international markets, domestic sales declined to 45% of total sales in each of fiscal 2010 and 2011. In fiscal 2012, domestic sales increased to 54%, with the full year impact of Energy Steel and additional U.S. Navy work. The Navy activity represents our production of surface condensers for the CVN-79 Gerald R. Ford Class nuclear carrier order that was won in Q3 fiscal 2010. This project was in excess of $25 million and is converting to revenue across multiple fiscal years.

Results of Operations

For an understanding of the significant factors that influenced our performance, the following discussion should be read in conjunction with our consolidated financial statements and the notes to our Consolidated Financial Statements included in Item 8 of Part II of this Annual Report on Form 10-K.

The following table summarizes our results of operations for the periods indicated:

                                                Year Ended March 31,
                                          2012          2011          2010
             Net sales                  $ 103,186     $  74,235     $  62,189
             Net income                 $  10,553     $   5,874     $   6,361
             Diluted income per share   $    1.06     $    0.59     $    0.64
             Total assets               $ 114,977     $ 118,071     $ 108,979

Fiscal 2012 Compared with Fiscal 2011

Sales for fiscal 2012 were $103,186, up $28,951 or 39%, as compared with sales of $74,235 for fiscal 2011. The increase was driven by organic growth as well as the full year impact of our acquisition of Energy Steel. Organic sales grew $17,478, or 26%, representing 60% of the growth in fiscal 2012. Sales from Energy Steel, which was acquired in December 2010 of fiscal 2011, increased $11,473, representing the remaining 40% of the growth in fiscal 2012. All comparisons discussed include a full year of financial results for Energy Steel in fiscal 2012 compared with approximately 3 1/2 months of financial results in fiscal 2011.

Domestic sales increased by $22,074 in fiscal 2012, driven by the full year impact of Energy Steel, increased conversion of the Navy project and strong organic growth. International sales accounted for 46% of all sales for fiscal 2012, down from 55% in fiscal 2011. International sales increased by $6,877 in fiscal 2012. By market, sales for fiscal 2012 were 35% to the refining industry, the same percentage as fiscal 2011, but a larger dollar amount, 28% to the power markets, including nuclear energy, up from 22% in fiscal 2011, 17% to the chemical and petrochemical industries, down from 22% in fiscal 2011, and 20% to other industrial applications (including the U.S. Navy), down from 21% in fiscal 2011.

Our gross margin for fiscal 2012 was 31.6% compared with 29.4% for fiscal 2011. Gross margins in fiscal 2012 improved compared with fiscal 2011 due to increased facility utilization at our Batavia plant, stronger sales and pricing for short-cycle orders and improved pricing on key projects resulting from strategic decisions regarding pricing. Gross profit for fiscal 2012 increased $10,784, compared with fiscal 2011. Gross profit increased primarily due to higher sales as well as the improved gross margin level.

Selling, general and administrative, or SG&A, expense for fiscal 2012 was $15,540, up 19% compared with $13,076 in fiscal 2011. Half of the increase in SG&A was related to the full year impact of owning Energy Steel. The remaining increase was due to the addition of staff to support current and future expected revenue growth. SG&A expense as a percentage of sales decreased in fiscal 2012 to 15.1% of sales compared with 17.6% of sales in fiscal 2011.

Interest income for fiscal 2012 was $58, down from $77 in fiscal 2011. This decrease was due to lower average levels of cash during fiscal 2012 compared with fiscal 2011.

Interest expense was $476 in fiscal 2012, up from $92 in fiscal 2011. The increase was due to the interest expense recognized related to the acquisition earn-out (reversing the discounting calculations made when estimating the payment of the earn-out) as well as interest charges for a research and development tax credit resolution with the IRS and other unrecognized tax benefits. The IRS tax resolution is discussed in more detail in Note 10 to the Consolidated Financial Statements in Item 8 of Part II of this Annual Report on Form 10-K.

Our effective tax rate in fiscal 2012 was 37% compared with an effective tax rate of 33% for fiscal 2011. The effective tax rate increased in fiscal 2012 due to a charge of $374 related to the resolution of an IRS audit and appeal related to research and development tax credits taken in tax years 2006 through 2008. Excluding this charge, the effective tax rate in fiscal 2012 was 34%. The tax rate in fiscal 2011 was adversely effected by acquisition-related costs which were not tax affected. Excluding the acquisition-related tax impact, the effective tax rate in fiscal 2011 was 32%. Included in fiscal 2012 and fiscal 2011 income tax expense were charges for unrecognized tax benefits of $41 and $32, respectively, related to research and development tax credits taken in tax years subsequent to 2008.

Net income for fiscal 2012 and fiscal 2011 was $10,553 and $5,874, respectively. Income per diluted share was $1.06 and $0.59 for the respective periods. Net income and income per diluted share were $10,986 and $1.10 for fiscal 2012 when excluding the impact of the IRS research and development resolution. Net income and income per diluted share were $6,407 and $0.64 for fiscal 2011 when excluding the transaction costs related to the Energy Steel acquisition.

Fiscal 2011 Compared with Fiscal 2010

Sales for fiscal 2011 were $74,235, a 19% increase, as compared with sales of $62,189 for fiscal 2010. The increase was driven by our acquisition of Energy Steel, which was owned by us for approximately 3 1/2 months in fiscal 2011, and by improvement in our base markets for petroleum-based products. Energy Steel contributed $5,808, or 48%, of the growth in fiscal 2011. Domestic sales increased by $5,431 in fiscal 2011, driven by our acquisition of Energy Steel. International sales accounted for 55% of all sales for fiscal 2011, the same as fiscal 2010. International sales increased by $6,615 in fiscal 2011, with increases in the Middle East and South America up $5,467 and $4,723, respectively, partly offset by slower sales in Asia, down $4,174. By market, sales for fiscal 2011 were 35% to the refining industry (down from 41% in fiscal 2010), 22% to the chemical and petrochemical industries (down from 35%) and 43% to other industrial applications (up from 24%), including nuclear energy and the U.S. Navy.

Our gross margin for fiscal 2011 was 29.4% compared with 35.7% for fiscal 2010. Gross margin in fiscal 2011 was impacted by certain project wins, which occurred in late fiscal 2010 and early fiscal 2011, during a period when pricing was extremely competitive due to the small number of available opportunities. In addition, fiscal 2010 margins, especially in the first half of the year, benefitted from projects won late in the last up cycle. Gross profit for fiscal 2011 decreased $380, compared with fiscal 2010. Gross profit decreased due to a lower gross margin, which was mostly offset by higher volume. Gross profit in fiscal 2011 was adversely impacted by inventory step-up and intangible asset amortization related to the Energy Steel acquisition. These charges were $247 in fiscal 2011.

SG&A and other expenses for fiscal 2011 were $13,076, up 7% compared with $12,189 in fiscal 2010. The increase in SG&A was related to our acquisition of Energy Steel, which had $764 of SG&A (including $53 of intangible asset amortization costs) related to post-acquisition operating costs. There was also $676 of transaction costs related to the acquisition. SG&A, excluding Energy Steel, decreased $553, driven by lower pension and variable compensation costs. SG&A and other expenses as a percentage of sales decreased in fiscal 2011 to 17.6% of sales compared with 19.6% of sales in fiscal 2010.

Interest income for fiscal 2011 was $77, up from $55 in fiscal 2010. This increase was due to higher average levels of cash during fiscal 2011 compared with fiscal 2010.

Interest expense was $92 in fiscal 2011, up from $36 in fiscal 2010. The increase was due to an interest charge for unrecognized tax benefits.

Our effective tax rate in fiscal 2011 was 33% compared with an effective tax rate of 37% for fiscal 2010. The tax rate in fiscal 2011 was adversely affected by acquisition-related costs which were not tax affected. Excluding the acquisition-related tax impact, the effective tax rate in fiscal 2011 was 32%. Included in fiscal 2011 and fiscal 2010 income tax expense was a charge for unrecognized tax benefits of $32 and $445, respectively, related to research and development tax credits taken in tax years 2006 through 2010. Such charge was management's estimate of our potential exposure related to the IRS examination which was resolved in fiscal 2012. Excluding the tax charge, our effective tax rate in fiscal 2010 was 32.5%.

Net income for fiscal 2011 and fiscal 2010 was $5,874 and $6,361, respectively. Income per diluted share was $0.59 and $0.64 for the respective periods. Excluding the transaction costs related to the Energy Steel acquisition, net income and income per diluted share was $6,407 and $0.64 in fiscal 2011.

Stockholders' Equity

The following discussion should be read in conjunction with our consolidated statements of changes in stockholders' equity that can be found in Item 8 of Part II of this Annual Report on Form 10-K. The following table shows the balance of stockholders' equity on the dates indicated:

March 31, 2012 March 31, 2011 March 31, 2010 $81,620 $73,655 $69,074

Fiscal 2012 Compared with Fiscal 2011

Stockholders' equity increased $7,965 or 11%, at March 31, 2012 compared with March 31, 2011. This increase was primarily due to net income earned in fiscal 2012, offset by 15 shares repurchased in fiscal 2012. A total of 362 shares have been repurchased, pursuant to our publicly announced stock repurchase program. At March 31, 2012, the number of shares remaining that had been approved for repurchase under the stock repurchase program was 638.

On March 31, 2012, our net book value was $8.20 up 10% over March 31, 2011.

Fiscal 2011 Compared with Fiscal 2010

Stockholders' equity increased $4,581 or 7%, at March 31, 2011 compared with March 31, 2010. This increase was primarily due to net income earned in fiscal 2011. We repurchased 59 shares in fiscal 2011.

On March 31, 2011, our net book value was $7.47 up 7% over March 31, 2010.
