IMMEDIATE RELEASE

PMFG, Inc. (parent of Peerless Mfg. Co.) Reports First Quarter Fiscal Year 2013 Financial Results

Dallas, Texas – November 8, 2012 – PMFG, Inc. (the “Company”) (NASDAQ: PMFG) today reported financial results for the first quarter ended September 29, 2012.

First Quarter Fiscal Year 2013 Compared to First Quarter Fiscal Year 2012

Revenue in the first quarter of fiscal 2013 increased $3.9 million or 13.4% to $33.0 million from increased international demand for products within the Process Products segment, as well as the overlap of the acquisition of Burgess-Manning GmbH completed in November 2011.

Gross profit increased in the current quarter by $2.7 million or 30.8% to $11.4 million attributed in part to the higher revenue. Gross margin increased as a percent of revenue from 29.9% to 34.5% on a change in product and geographic mix, as well as an increased focus on managing manufacturing costs. The closure of one of the Company’s domestic manufacturing facilities earlier in 2012 contributed to the improvement in manufacturing costs.

Operating expenses increased $1.1 million or 10.9% in the current quarter, of which $0.8 million resulted from the write-off of a customer receivable balance.

Interest expense declined 75.4% in the current quarter to $0.1 million on lower average balances outstanding. In the current quarter, the Company recorded a loss on extinguishment of debt totaling $0.3 million. Foreign exchange losses recognized in the quarter totaled $0.1 million compared to a $0.5 million loss in the prior quarter.

The net loss attributable to PMFG, Inc. common stockholders was $0.3 million, or ($0.01) per diluted share in the current quarter compared to a loss of $1.2 million or ($0.07) per diluted share in the prior year quarter.

Reporting Segments

Process Products segment revenue increased $4.5 million or 18.5% to $28.7 million compared to $24.2 million in the prior year quarter. The segment benefited from the overlap of the acquisition of Burgess-Manning GmbH completed in November 2011. Operating income increased $2.0 million or 60.5% to $5.4 million compared to $3.4 million in the prior year. The increase in operating income is attributed primarily to increased revenue and changes in product and geographic mix this quarter compared to the same quarter in the prior year.

The Environmental Systems segment revenue decreased $0.6 million or 12.2% to $4.3 million compared to $4.9 million in the prior year quarter. The decline in revenue is attributed to the low level of bookings in early fiscal 2012, as well as the dampened demand for SCR equipment in the United States. Operating income increased $0.1 million to $0.6 million compared to $0.5 million in the prior year. The increase in operating income is attributed primarily to a lower selling and engineering costs relative to revenue.

Financial Condition and Cash Flows

At September 29, 2012, the Company reported $60.1 million of cash and cash equivalents, excluding $8.1 million of cash and cash equivalents which is restricted as security for outstanding letters of credit, total assets of $186.7 million, net working capital of $77.5 million and a current ratio of 2.6 to 1.0.

Unrestricted cash and cash equivalents increased $7.8 million during the first quarter fiscal 2013 compared to an increase of $3.2 million in the first quarter fiscal 2012, attributed in part to an improvement in collection of accounts receivable. For fiscal year 2013, cash flows included $9.2 million provided by operating activities, ($0.5) million used in investing activities, ($0.6) million used in financing activities and ($0.3) million effect of exchange rate changes on cash.

Peter J. Burlage, Chief Executive Officer

Peter Burlage, President and Chief Executive Officer of PMFG stated, “Our first quarter results were highlighted by increased year over year revenue and contribution margin from our Process Products segment. Demand drivers for energy infrastructure needs remain intact, and we are optimistic about medium to long-term infrastructure investment opportunities. Our Environmental Systems segment recorded flat year over year net bookings and will continue to be challenging throughout the fiscal year as we experience dampened demand for SCR equipment in the United States.

“On a global basis, we continue to benefit from increased demand for Process Product systems, although we are seeing a slowing in the decision by customers to release capital projects to production. We are experiencing longer sales cycle times, most notably in the time between contract award and purchase order receipt, as well as longer time spans between purchase order receipt and the customer release of the project to move into manufacturing.

“We are seeing positive indications that the global demand for nuclear energy is poised to move forward. In China, the newly positioned government officials recently signed the acceptability of safety measures in the plant designs. This is an important step forward in restarting construction projects halted following the events in Fukushima. In the United States and in Europe, we are in active discussions with customers regarding the reduction of the manufacturing cycle in order to meet their accelerated delivery timetables for replacement steam dryers.”

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 loss of extinguishment of debt in the three months ended September 29, 2012. Management believes that excluding this item 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.
