Exhibit 99.1 Press Release

"Our strong Q3 2014 gross margin performance was primarily attributable to the strength of MRO/UE (maintenance, repair, operations/upgrade and expansion) revenue during the period. MRO/UE represented 76% of total revenue in Q3 2014 and revenue growth of 22% over MRO/UE revenue in Q3 2013. In addition to strong gross profit performance, we also set records for earnings and free cash flow per share in Q3 2014," said Rodney Bingham, President and Chief Executive Officer.

Q3 2014 revenue of $71.5 million reflected a decrease of 7% compared to revenue of $76.8 million in Q3 2013, which was largely attributable to a decline in Greenfield activity in Asia and Canada. Greenfield projects represented approximately 24% of Q3 2014 revenue and MRO/UE represented approximately 76% of Q3 2014 revenue. Foreign currency negatively impacted revenue by $1.2 million in Q3 2014, an impact of approximately 2%, mostly due to weakness in the Canadian dollar.

Q3 2014 GAAP fully diluted EPS was a record $0.39, an increase of $0.15 relative to Q3 2013, and Adjusted EPS of $0.37, an increase of $0.13 relative to Adjusted EPS in Q3 2013. The adjustment to GAAP net income in Q3 2014 is a decrease to tax expense related to the release of an accrual for a previously estimated tax benefit that was determined not to be payable to the former owners of the Company. See the tables titled "Reconciliation of Net Income to Adjusted Net Income and Adjusted EPS" for additional details.

On a year to date basis, the Company generated revenue of $209.8 million versus $212.4 million in FY 2013. The decline in revenue in the year-over-year period was largely attributable to a decline in Greenfield activity in Asia. Foreign currency negatively impacted revenue by $2.7 million, relative to the first nine months of FY 2013, primarily attributed to the weakness in the Canadian dollar.

GAAP net income year to date was $16.2 million, or $0.51 per fully diluted share, versus $21.3 million and $0.67 per fully diluted share in FY 2013. Adjusting for the redemption and refinancing of our senior secured notes and certain tax benefits, our Adjusted net income in the first nine months of FY 2014 was $29.0 million, or $0.90 per fully diluted share, versus $23.2 million and $0.73 per fully diluted share in FY 2013.

Disclosure in this release of "Adjusted EPS," "Adjusted EBITDA," "Adjusted net income," "Free cash flow per share" and "Return on equity" which are "non-GAAP financial measures" as defined under the rules of the Securities and Exchange Commission (the "SEC"), are intended as supplemental measures of our financial performance that are not required by, or presented in accordance with, U.S. generally accepted accounting principles ("GAAP"). "Adjusted net income" and "Adjusted fully diluted earnings per share (or EPS)" represents net income before certain expenses related to the release of a liability for uncertain tax positions, the release of an accrual for obligations due to settle the CHS Transactions that we did not owe to our former owners and expenses related to certain extraordinary transactions, such as our, debt redemptions, secondary public offering and refinancing of our revolving line of credit, per fully-diluted common share. "Adjusted EBITDA" represents net income before interest expense (net of interest income), income tax expense, depreciation and amortization expense and other non-cash

charges such as stock-based compensation expense, and expenses incurred with transactions not associated with our ongoing operations, such as the loss on retirement of debt and our fiscal 2013 shelf registration and secondary public offering. "Return on equity for the three month period ended December 31, 2013" represents Adjusted EBITDA for the three month period ended December 31, 2013 that is multiplied times four to represent a full year's results, divided by the average of total shareholders' equity at December 31, 2013 and September 30, 2013. "Return on equity for the nine month period ended December 31, 2013" represents Adjusted EBITDA for the nine month period ended December 31, 2013 that is multiplied by four-thirds to represent a full year's results, divided by the average of total shareholders' equity at December 31, 2013 and March 31, 2013. We believe that the average shareholders' equity properly accounts for net income that occurred during the three and nine months ended December 31, 2013. "Free cash flow per share" represents cash provided by operations less cash used for the purchase of property plant and equipment. The resultant cash provided or used is then divided by the fully diluted common shares outstanding. Foreign currency impact on revenue is calculated by comparing actual current period revenues in U.S Dollars to the theoretical U.S. Dollar revenues we would have achieved based on the weighted-average foreign exchange in effect in the comparative prior periods for all applicable foreign currencies.

We believe these non-GAAP financial measures are meaningful to our investors to enhance their understanding of our financial performance and are frequently used by securities analysts, investors and other interested parties to compare our performance with the performance of other companies that report Adjusted EPS, Adjusted EBITDA, Adjusted net income, Free cash flow per share or Return on equity. Adjusted EPS, Adjusted EBITDA, Adjusted net income, Free cash flow per share and Return on equity should be considered in addition to, not as substitutes for, income from operations, net income, net income per share, net cash provided by operating activities and other measures of financial performance reported in accordance with GAAP. Our calculation of Adjusted EPS, Adjusted EBITDA, Adjusted net income, Free cash flow per share and Return on equity may not be comparable to similarly titled measures reported by other companies. For a description of how Adjusted EPS, Adjusted EBITDA, Adjusted net income, Return on equity and Free cash flow per share are calculated and reconciliations to the corresponding GAAP measures, see the sections of this release titled "Reconciliation of Net Income to Adjusted EBITDA and Return on Equity," and "Reconciliation of Net Income to Adjusted Net Income and Adjusted EPS" and "Reconciliation of Cash Provided by Operating Activities to Free Cash Flow per Share."

This release may include forward-looking statements within the meaning of the U.S. federal securities laws in addition to historical information. These forward-looking statements include, without limitation, statements regarding our industry, business strategy, plans, goals and expectations concerning our market position, future operations, margins, profitability, capital expenditures, liquidity and capital resources and other financial and operating information. When used, the words "anticipate," "assume," "believe," "budget," "continue," "could," "estimate," "expect," "intend," "may," "plan," "potential," "predict," "project," "will," "future" and similar terms and phrases are intended to identify forward-looking statements in this release. Forward-looking statements reflect our current expectations regarding future events, results or outcomes. These expectations may or may not be realized. Some of these expectations may be based upon assumptions, data or judgments that prove to be incorrect. In addition, our business and operations involve numerous risks and uncertainties, many of which are beyond our control,

Actual events, results and outcomes may differ materially from our expectations due to a variety of factors. Although it is not possible to identify all of these factors, they include, among others, (i) general economic conditions and cyclicality in the markets we serve; (ii) future growth of energy and chemical processing capital investments; (iii) changes in relevant currency exchange rates; (iv) our ability to comply with the complex and dynamic system of laws and regulations applicable to international operations; (v) a material disruption at any of our manufacturing

facilities; (vi) our dependence on subcontractors and suppliers; (vii) our ability to obtain standby letters of credit, bank guarantees or performance bonds required to bid on or secure certain customer contracts; (viii) competition from various other sources providing similar heat tracing products and services, or other alternative technologies, to customers; (ix) our ability to attract and retain qualified management and employees, particularly in our overseas markets; (x) our ability to continue to generate sufficient cash flow to satisfy our liquidity needs; (xi) the extent to which federal, state, local and foreign governmental regulation of energy, chemical processing and power generation products and services limits or prohibits the operation of our business; and (xii) other factors discussed in more detail under the caption "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended March 31, 2013, as filed with the Securities and Exchange Commission on June 10, 2013. Any one of these factors or a combination of these factors could materially affect our financial condition, results of operations and cash flows and could influence whether any forward-looking statements contained in this release ultimately prove to be accurate.
