IMMEDIATE RELEASE

PMFG, Inc. (Parent of Peerless Mfg. Co.) Reports Fourth Quarter and Fiscal Year 2008 Financial Results

Dallas, Texas – September 8, 2008 – PMFG, Inc. (the “Company”) (Nasdaq: PMFG) today reported financial results for the fourth quarter and fiscal year ended June 30, 2008.

On August 15, 2008, Peerless Mfg. Co. completed a holding company reorganization in which Peerless became a wholly owned subsidiary of PMFG, Inc. Shareholders of Peerless received two shares of common stock of PMFG for each outstanding share of common stock of Peerless held prior to the reorganization. As a result, the reorganization also had the effect of a two-for-one stock split. The Company’s business, operations and management did not change as a result of this reorganization. Share and per share amounts for all financial periods presented in this press release have been retroactively adjusted to give effect to the reorganization, including the two-for-one exchange of PMFG common stock for Peerless common stock.

On April 30, 2008, the Company acquired Nitram Energy, Inc. and since the date of acquisition has included Nitram’s financial results, including purchase accounting adjustments, in the Company’s results for the fourth quarter and fiscal year 2008.

Fourth Quarter Fiscal Year 2008

Revenues for the fourth quarter of fiscal year 2008 were $40.9 million, an increase of $14.7 million, or 56.1%, compared to revenues of $26.2 million for the fourth quarter of fiscal year 2007.

In the fourth quarter of fiscal year 2008, the Company recorded as part of the purchase accounting for the Nitram acquisition, $6.4 million and $4.8 million in fair value adjustments related to backlog and inventory acquired, respectively. Also during the fourth quarter, the Company recorded as part of cost of goods sold $2.7 million of backlog amortization expense and an additional $2.3 million of expense related to the fair value inventory adjustment. The remaining balance of the backlog intangible asset and the fair value adjustment related to inventory acquired will be expensed over an estimated remaining life of six months.

Peter J. Burlage, Chief Executive Officer

Peter J. Burlage, Chief Executive Officer, stated, “We had an outstanding year in fiscal 2008. Our revenues reached $140.5 million and our net earnings were $8.4 million, or $11.7 million excluding $5.0 million of pre-tax charges against our gross margins for the purchase accounting adjustment related to Nitram’s backlog and inventory. I’m pleased with the progress we have made integrating Nitram. Both of our operating segments reported higher revenues and increased operating income for fiscal year 2008. We continue to experience strong demand for our systems and products, particularly those used in natural gas transmission and natural gas power generation, as evidenced by our $107 million backlog at June 30, 2008. Our $97 million backlog at June 30, 2007 included a $30 million environmental systems order. We believe that this strong backlog, along with the combined resources of our integrated global operations will provide us with the foundation for continued growth in fiscal year 2009.”

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 purchase accounting associated with the acquisition of Nitram Energy Inc. in fiscal 2008 and the sale of our former headquarters facility in fiscal 2007. 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.
