Peter J. Burlage, Chief Executive Officer

Peter J. Burlage, Chief Executive Officer, stated, “While the financial results for the quarter weren’t as strong as we would like, there is much to be positive about in the second quarter. Backlog is up 11% quarter over quarter and 28% year over year, our prospects are strengthening in a number of markets, our liquidity position provides continued financial flexibility and bookings and bids have improved. The increase in our backlog is expected to result in improved financial performance in the coming periods. Looking at our operating performance in the second quarter, we continued to achieve acceptable margin levels in the current operating environment due to a combination of product mix and from our efforts at cost improvement and working capital management.

“Our Environmental Systems business continues to achieve the results we would expect at this point in the business cycle and given the demand for power generation. The Environmental Systems segment hit what we believe to be trough levels during the first half of the fiscal year, as it typically lags GDP, but we believe we are beginning to see evidence of a turn in the power marketplace. We are encouraged by data suggesting continued industrial expansion and increasing electricity consumption, which has led to higher utilization of the U.S. power generation fleet. Additionally, the multiple EPA regulations expected to be completed in 2011 are leading power generation providers to take a comprehensive look at their entire power generation system to determine the best path to comply with the new rules.

“We continue to be excited about our CEFCO aerodynamic reactor technology used in the selective capture and removal of NOx, SOx, CO2 and Hg. We recently moved one step closer to a full-scale system that could be available for commercialization the early part of fiscal year 2012 and we are eager to review and report on the results of this activity. Testing of a 600 lb/hr CEFCO system commenced at our test facility in January 2011.

“Looking ahead, while new awards during the three month period ended January 1, 2011 were modest, we believe the markets we serve continue to be robust and that the outlook for our business remains strong, particularly in the Middle East and Asia Pacific regions. With approximately one hundred million dollars in backlog, we remain committed to our strategic vision and belief that diversification and expansion of our end markets, a broader geographic reach and development of new technology, will strengthen and grow the company over time,” concluded Burlage.

Preferred Stock Conversions

As of February 7, 2011, the holders of 19,340 shares of Preferred Stock elected to convert their Preferred Stock into 2, 417,500 shares of the Company’s common stock. This represents approximately 92% of the Preferred Stock, which has now been converted. In connection with these conversions, we paid the holders of Preferred Stock cash payments for accrued and unpaid dividends on the converted shares and are now no longer required to pay dividends on the converted shares of Preferred Stock. The Company is uncertain as to when or how many additional holders of Preferred Stock will exercise their right to convert some or all of their shares in the future.

STATEMENT REGARDING NON-GAAP RESULTS

PMFG, Inc. has provided a reconciliation of non-GAAP measures in order to provide the users of this financial information with a better understanding of the impact on our financial results resulting from the issuance of preferred stock and related fair value adjustment to the derivative liability in fiscal 2011 and 2010 and the loss on the extinguishment of debt related to unamortized debt issuance costs on our retired subordinated term debt, in fiscal 2010. Management believes that excluding these items from the Company’s financial results provides investors with a clearer perspective of the current underlying operating performance of the Company, a clearer comparison between results in different periods and greater transparency regarding supplemental information used by management in its financial and operational decision making. These non-GAAP measures are not measurements under accounting principles generally accepted in the United States. These measures should be considered in addition to, but not as a substitute for, the information contained in our financial statements prepared in accordance with GAAP.
