These forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. 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 such as the anticipated financial performance of our Powerblanket acquisition, our execution of our strategic initiatives, our ability to complete the disposition of our Russian subsidiary and anticipated timing and

When used herein, the words "anticipate," "assume," "believe," "budget," "continue," "contemplate," "could," "should" "estimate," "expect," "intend," "may," "plan," "possible," "potential," "predict," "project," "will," "would," "future," and similar terms and phrases are intended to identify forward-looking statements in this presentation. 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, which could result in our expectations not being realized or otherwise materially affect our financial condition, results of operations and cash flows.

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) the outbreak of a global pandemic, including the current pandemic (COVID-19 and its variants); (ii) general economic conditions and cyclicality in the markets we serve; (iii) future growth of energy, chemical processing and power generation capital investments; (iv) our ability to operate successfully in foreign countries; (v) our ability to successfully develop and improve our products and successfully implement new technologies; (vi) competition from various other sources providing similar heat tracing and process heating products and services, or alternative technologies, to customers; (vii) our ability to deliver existing orders within our backlog; (viii) our ability to bid and win new contracts; (ix) the imposition of certain operating and financial restrictions contained in our debt agreements; (x) our

revenue mix; (xi) our ability to grow through strategic acquisitions; (xii) our ability to manage risk through insurance against potential liabilities (xiii) changes in relevant currency exchange rates; (xiv) tax liabilities and changes to tax policy; (xv) impairment of goodwill and other intangible assets; (xvi) our ability to attract and retain qualified management and employees, particularly in our overseas markets;

1. our ability to protect our trade secrets; (xviii) our ability to protect our intellectual property; (xix) our ability to protect data and thwart potential cyber-attacks; (xx) a material disruption at any of our manufacturing facilities; (xxi) our dependence on subcontractors and third-party suppliers; (xxii) our ability to profit on fixed-price contracts; (xxiii) the credit risk associated to our extension of credit to customers; (xxiv) our ability to achieve our operational initiatives; (xxv) unforeseen difficulties with expansions, relocations, or consolidations of existing facilities; (xxvi) potential liability related to our
   products as well as the delivery of products and services; (xxvii) our ability to comply with foreign anti-corruption laws; (xxviii) export control regulations or sanctions; (xxix) changes in government administrative policy; (xxx) the current geopolitical instability in Russia and Ukraine and related sanctions by the U.S. and Canadian governments and European Union; (xxxi) environmental and health and safety laws and regulations as well as environmental liabilities; and (xxxii) climate change and related regulation of greenhouse gases, and (xxxiii) those factors listed under Item 1A "Risk Factors" included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2022 as filed with the Securities and Exchange Commission (the "SEC") on May 26, 2022 and in any subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K or other filings that we have filed or may file with the SEC. Any one of these factors or a combination of these factors could materially affect our future results of
   operations and could influence whether any forward-looking statements contained in this presentation ultimately prove to be accurate. Our forward-looking statements are not guarantees of future performance, and actual results and future performance may differ materially from those suggested in any forward-looking statements. We do not intend to update these statements unless we are required to do so under applicable securities laws.

NON-GAAP FINANCIAL MEASURES

Disclosure in this presentation of "Adjusted EPS," "Adjusted EBITDA," "Adjusted EBITDA margin," "Adjusted Net Income/(Loss)" and "Free Cash Flow" 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/(Loss)" and "Adjusted EPS" (or "Adjusted fully diluted EPS") represent net income/(loss) before the impact of restructuring and other charges/(income), amortization of intangible assets, tax expense for impact of foreign rate increases, loss on debt extinguishment, the benefit from the CEWS, Acquisition related cost and any tax effect of such adjustments. "Adjusted EBITDA" represents net income/(loss) before interest expense (net of interest income), income tax expense, depreciation and amortization expense, stock-based compensation expense, costs associated with our restructuring and other income/(charges), the loss on our debt extinguishment, and income related to the CEWS. "Adjusted EBITDA margin" represents

Adjusted EBITDA as a percentage of total revenue. "Free Cash Flow" represents cash provided by operating activities less cash used for the purchase of property, plant, and equipment, net of sales of rental equipment and proceeds from sales of land and buildings.

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 EBITDA margin or Adjusted Net Income/(Loss). Adjusted EPS, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income/(Loss) and Free Cash Flow should be considered in addition to, and not as substitutes for, income from operations, net

income/(loss), net income/(loss) per share and other measures of financial performance reported in accordance with GAAP. We provide Free Cash Flow as a measure of liquidity. Our calculation of Adjusted EPS, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income/(Loss) and Free Cash Flow may not be comparable to similarly titled measures reported by other companies. For a description of how Adjusted EPS, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income/(Loss) and Free Cash Flow are calculated and reconciliations to the corresponding GAAP measures, see the sections of our latest Press Release titled "Reconciliation of Net Income/(Loss) to Adjusted EBITDA," "Reconciliation of Net Income/(Loss) to Adjusted Net Income/(Loss) and Adjusted EPS" and "Reconciliation of Cash Provided by Operating Activities to Free Cash Flow."
