Fiscal 2013 and the Near-Term Market Conditions

We believe current market conditions are more positive than they have been in the past few years. The business environment in our markets appears to continue to be improving and we believe that our customers now may be more inclined to move forward with their projects. This supports our belief that our oil refining, petrochemical and related markets remain in the early stages of a business recovery. We believe the quantity, magnitude and quality of our bidding activity supports this view of improved market conditions. We also believe that delayed purchase decisions by our customers are more due to their timing than conditions of our markets.

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, we believe that improved access to capital has resulted in projects being released.

• 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 increased demand for refined petroleum products such as gasoline. This renewed demand is driving increased investment in petrochemical and refining projects. Although economic growth in Asia appears to be moderating to a lower level, we believe that it remains a fast growing area and Chinese and Indian investments in refining, petrochemical and energy facilities appear to continue to be strong.

• 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.

• 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 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 feedstocks.

• The recent dramatic reduction in natural gas costs in the U.S. has led to a revival in the U.S. petrochemical market and has created interest in potential major investment. There are numerous projects in the planning or initial engineering phases for the construction of new petrochemical producing facilities, including ethylene, ammonia and urea. 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 also being discussed by petrochemical producers for the first time in well over a decade. Lower natural gas costs are driven by recent technology advancements in drilling, and have created 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 that future investment in the U.S. petrochemical market could be significant.

• 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 potential impact of increased use of natural gas for power generation.

• Investment in new nuclear power capacity 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. However, we believe that the need for additional safety and back up redundancies at the 104 existing domestic nuclear plants in the U.S. could increase demand for Energy Steel's products in the near-term.

We expect that the consequences of these near-term trends, and specifically projected expansion in petrochemical and oil refining outside of North America, primarily in the growing Asian and South American markets, will result in continued pressure on our pricing and gross margins, as these markets historically provided lower margins than North American refining markets. A potential offset 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 continue to expect our new order levels to remain volatile. We expect that this volatility will result in both relatively strong and weak quarters over the next several quarters. Quarterly orders can vary significantly as indicated in the following chart which depicts our quarterly order levels for the first, second and third quarters of fiscal 2013 as well as the four quarters of each of fiscal 2012 and the fiscal year ending March 31, 2011, which we refer to as "fiscal 2011".

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. We believe looking at trailing twelve month order levels provides a better view of the direction of our business. In the near-term, we expect to continue 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.

Expect Stronger International Growth in Refining and Chemical Processing while Domestic Growth is Expected to be in Nuclear Power, U.S. Navy Projects and Petrochemical Industries

We expect growth in the refining and chemical processing markets to be driven by emerging markets, as well by U.S. petrochemical growth, should it occur. 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 of finished product from the Middle East to North America and Europe is expected.

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

• Increased global regulations over the refining, petrochemical and nuclear power industries are expected to continue to drive requirements for capital investments.

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

• Shale gas development and the resulting increase in available low cost natural gas in the U.S. may change the power landscape. This may drive more future investment in natural gas or combined cycle power plants and away from planned nuclear power facilities.

• The lower cost of natural gas and its by-product, ethane, is leading to renewed planning and investment in North American based chemical/petrochemical facilities to meet domestic needs. Ethane, as a feedstock to ethylene production, is now at a cost advantage to naphtha, the oil-based feedstock for ethylene production used in much of the rest of the world. Because of this cost competitive position of ethane, the opportunity to invest in North American chemical/petrochemical plants is possible for the first time in well over a decade.

• Construction of new petrochemical plants in the Middle East is planned to meet increased global demand.

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

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

• 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.

We believe that 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, in the first nine months of fiscal 2013 were 53%. This is similar to fiscal 2012, where domestic sales had increased to 54% of total sales, up from 45% in each of fiscal 2010 and 2011. The increase in

domestic sales has been due to our acquisition of Energy Steel in late fiscal 2011, which primarily has a domestic customer base, and the conversion of the U.S. Navy order. The U.S. Navy activity represents our production of surface condensers for the CVN-79 Gerald R. Ford Class nuclear carrier, an order that was won in the third quarter of our fiscal year ended March 31, 2010.

The Third Quarter and First Nine Months of Fiscal 2013 Compared With the Third Quarter and First Nine Months of Fiscal 2012

Sales for the third quarter of fiscal 2013 were $25,633, a 5% increase as compared with sales of $24,329 for the third quarter of fiscal 2012. The increase in the current quarter's sales was driven by improved pricing and added volume from increased subcontracting. International sales were up $3,830 compared with the third quarter of fiscal 2012, primarily driven by increased sales to the Middle East. Domestic sales decreased $2,526 in the third quarter of fiscal 2013 compared with the same quarter in fiscal 2012. Sales in the three months ended December 31, 2012 were 43% to the refining industry, 25% to the chemical and petrochemical industries, 16% to the power industry, including the nuclear market and 16% to other commercial and industrial applications. Sales in the three months ended December 31, 2011 were 31% to the refining industry, 19% to the chemical and petrochemical industries, 27% to the power industry, including the nuclear market and 23% to other commercial and industrial applications. Fluctuations in sales among markets, products and geographic locations can vary measurably from quarter-to-quarter based on, among other things, timing and magnitude of projects. See "Fiscal 2013 and Near Term Market Conditions" above. For additional information on anticipated future sales and our markets, see "Orders and Backlog" below.

Sales for the first nine months of fiscal 2013 were $74,068, a decrease of 11% compared with sales of $82,936 for the first nine months of fiscal 2012. The decrease in year-to-date sales was primarily due to lower international sales, pricing and volume. International sales accounted for 47% and 48% of total sales for the first nine months of fiscal 2013 and fiscal 2012, respectively. International sales year-over-year decreased $5,185, or 13%. In the first nine months of fiscal 2013, sales to the Middle East declined $3,115. The remaining sales decrease came from Asia and South America. Domestic sales decreased $3,683 or 9%, in the nine months ended December 31, 2012 compared with the nine months ended December 31, 2011. Sales in the

first nine months of fiscal 2013 were 30% to the refining industry, 28% to the chemical and petrochemical industries, 21% to the power industry, including the nuclear market, and 21% to other commercial and industrial applications. Sales in the first nine months of fiscal 2012 were 38% to the refining industry, 14% to the chemical and petrochemical industries, 27% to the power industry, including the nuclear market, and 21% to other commercial and industrial applications.

Our gross profit margin for the third quarter of fiscal 2013 was 28% compared with 27% for the third quarter of fiscal 2012. Gross profit for the third quarter of fiscal 2013 increased to $7,128 from $6,462, or 10%, compared with the same period in fiscal 2012. Gross profit margin and dollars in the third quarter increased primarily due to improved pricing on projects won a year into the recovery of our markets.

Our gross profit margin for the first nine months of fiscal 2013 was 29% compared with 33% for the first nine months of fiscal 2012. Gross profit dollars for the first nine months of fiscal 2013 decreased 23% to $21,277, compared with the same period in fiscal 2012, which had gross profit of $27,459. The decrease in gross profit margin and dollars had occurred in the first two quarters of fiscal 2013 compared with the same period of fiscal 2012. Gross profit percentage and dollars decreased in the nine-month period primarily due to lower volume and capacity utilization as well as the conversion of projects during the first two quarters of fiscal 2013, which had less favorable pricing compared with the projects converted in the first two quarters of fiscal 2012. Certain projects which converted in the first half of the prior fiscal year were won during the prior market peak, when pricing was strong. This trend reversed itself for the third quarter of fiscal 2013 compared with the same period in the prior year, but the increase in gross profit margin and dollars in the current quarter was not sufficient to offset the decrease experienced in the first half of the year.

Selling, general and administrative ("SG&A") expense in the three month period ended December 31, 2012 decreased $632, or 17% compared with the same period of the prior year. This decrease was due primarily to the reversal of a $975 reserve related to the expected value of the earn out from the Energy Steel acquisition.

The Energy Steel acquisition provided for a potential earn out to the seller of up to $1,000 per year for each of the first two full calendar years (calendar years 2011 and 2012) that we owned Energy Steel. The first year, calendar year 2011, the earn out was achieved and paid to the seller in January 2012. The earn out for the second year, calendar year 2012, had been partly reserved for at the time of acquisition with the remaining charges added subsequent to the acquisition. However, due to lower order volume levels experienced in calendar year 2012 and project timing, the Energy Steel earn out criteria was not achieved. As a result, the reserve of $975 was adjusted to $0, and $975 was recorded as a reduction of selling, general and administrative expenses in the third quarter.

Selling, general and administrative ("SG&A") expense in the nine month period ended December 31, 2012 decreased $209, or 2%, compared with the same periods of the prior year. Excluding the impact of the reversal of the earn out reserve described above, SG&A increased 9% in the three month period and 6% in the nine month period ended December 31, 2012, compared to the same periods in the prior year.

The increase for both the three and nine-month periods was due to increased headcount, as we prepare for the anticipated continued recovery in our markets, offset by certain costs related to lower sales volume.

SG&A expense as a percent of sales for the three and nine-month periods ended December 31, 2012 was 12% and 16%, respectively. Excluding the impact of the earn out reserve reversal noted above, SG&A expense as a percentage of sales was 16% and 17%, respectively. This compared with 16% and 14%, respectively for the same periods of the prior year. SG&A expense as a percent of sales increased, primarily due to increased commissions, headcount costs and lower comparable sales.

Interest income was $13 and $38 for the three and nine-month periods ended December 31, 2012, compared with $12 and $48 for the same periods ended December 31, 2011. The low level of interest income relative to the amount of cash invested reflects the persistent low level of interest rates on money market funds and short term U.S. government securities in which we invest net cash available from operations.

Interest expense was $19 and $(271) for the three and nine-month periods ended December 31, 2012, compared with $55 and $260 for the same periods ended December 31, 2011. It is our policy to recognize any interest related to uncertain tax positions in interest expense. In the second quarter of fiscal 2013, due to lower than expected assessments by the IRS, we reversed provisions that had been made in earlier periods for interest related to previously uncertain tax positions. See Note 13 of the notes to our unaudited condensed consolidated financial statements included in Part I, Item I, of this Quarterly Report on Form 10-Q.

We project our effective tax rate in fiscal 2013 will be between 29% and 30%. The tax rate used to reflect income tax expense in the current quarter was 23%, and the tax rate for the first nine months of fiscal 2013 was 29%. The lower tax rate realized in the third quarter was related to the reversal of the Energy Steel earn out reserve discussed above, which was not tax affected, since it was a purchase price adjustment. Excluding this reversal, the effective tax rate in each of the three and nine-month periods ended December 31, 2012 would have been 32%. The actual annual effective tax rate for fiscal 2012 was 37%, which . . .
