Basis of Presentation	NOTE 2. BASIS OF PRESENTATION (a) Statement of Compliance These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and were approved and authorized for issue by the Board of Directors on February 23, 2022. Certain prior year amounts have been reclassified to conform with the current period’s presentation. (b) Basis of Measurement The consolidated financial statements are prepared on a historical cost basis except as detailed in the accounting policies disclosed in Note 3. The accounting policies described in Note 3 and Note 4 have been applied consistently to all periods presented in these consolidated financial statements. Standards and guidelines issues but not yet effective for the current accounting period are described in Note 6. (c) Functional Currency and Presentation Currency These consolidated financial statements are presented in Canadian dollars, which is the Company’s presentation currency. Transactions of the Company’s individual entities are recorded in their own functional currency based on the primary economic environment in which it operates. (d) Use of Estimates and Judgment The timely preparation of financial statements requires that management make estimates and assumptions and use judgment. Accordingly, actual results may differ from estimated amounts as future confirming events occur. Significant estimates and judgment used in the preparation of the financial statements are described in Note 5. (e) Basis of Consolidation These consolidated financial statements include the accounts of the Company and its subsidiaries. Subsidiaries are fully consolidated from the date of acquisition and continue to be consolidated until the date that control ceases. The financial statements of the subsidiaries are prepared for the same reporting period as the parent Company, using consistent accounting policies. All intra-group balances, income and expenses, and unrealized gains and losses resulting from intra-group transactions are eliminated in full.

Summary of Significant Accounting Policies	NOTE 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) Investments in Associates and Joint Ventures The Company uses the equity method to account for its 45 percent investment in Roska DBO Inc. (“Roska DBO”) and its 65 percent investment in a joint venture in Brazil. Under the equity method, the investment is carried on the consolidated statements of financial position at cost plus post acquisition changes in the Company’s share of net assets of the associate or joint venture. The consolidated statements of earnings reflect the Company’s share of the results of operations of associates and joint ventures. Unrealized gains and losses resulting from transactions between the Company and associates are eliminated to the extent of the interest in the associate or joint venture. The Company’s share of profits from associates and joint ventures is shown on the face of the consolidated statements of earnings. This is the profit attributable to equity holders of the associate and joint venture partners and, therefore, is profit after tax and non-controlling (b) Foreign Currency Translation In the accounts of individual subsidiaries, transactions in currencies other than the Company’s functional currency are recorded at the prevailing rate of exchange at the date of the transaction. At year end, monetary assets and liabilities denominated in foreign currencies are translated at the rates of exchange prevailing at that date. Non-monetary Non-monetary The assets and liabilities on the statements of financial position of foreign subsidiaries are translated into Canadian dollars at the rates of exchange prevailing at the reporting date. The statements of earnings of foreign subsidiaries are translated at average exchange rates for the reporting period. Exchange differences arising on the translation of net assets are taken to accumulated other comprehensive income. All foreign exchange gains and losses are taken to the consolidated statements of earnings with the exception of exchange differences arising on monetary assets and liabilities that form part of the Company’s net investment in subsidiaries. These are taken directly to other comprehensive income until the disposal of the foreign subsidiary at which time the unrealized gain or loss is recognized in the consolidated statements of earnings. On the disposal of a foreign subsidiary, accumulated exchange differences are recognized in the consolidated statements of earnings as a component of the gain or loss on disposal. (c) Business Combinations Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at fair value on the date of the acquisition. Acquisition costs incurred are expensed and included in selling and administrative expenses, except for those associated with the issuance of debt, which are included in the initial carrying amount of the liability. Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred over the net identifiable assets acquired and liabilities assumed. (d) Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation and any accumulated impairment losses. Cost comprises the purchase price or construction cost and any costs directly attributable to making the asset capable of operating as intended. Depreciation is provided using the straight-line method over the estimated useful lives of the various classes of assets and commences when the assets are ready for intended use. Asset Class Estimated Useful Life Range Buildings 5 to 20 years Equipment 2 to 20 years Major renewals and improvements are capitalized when they are expected to provide future economic benefit. When significant components of property, plant and equipment are required to be replaced at intervals, the Company derecognizes the replaced part, and recognizes the new part with its own associated useful life and depreciation. No depreciation is charged on land or assets under construction. Repairs and maintenance costs are charged to operations as incurred. The carrying amount of an item of property, plant and equipment is derecognized on disposal or when no future economic benefits are expected from its use or disposal. The gain or loss arising from derecognition of property, plant and equipment is included in the consolidated statements of earnings when the item is derecognized. Each asset’s estimated useful life, residual value, and method of depreciation are reviewed and adjusted, if appropriate, at each year end, or when factors and circumstances suggest a different useful life for the asset. (e) Rental Equipment Rental equipment is stated at cost less accumulated depreciation and any accumulated impairment losses. Depreciation is provided using the straight-line method over the estimated useful lives of the assets, which are generally between 5 and 20 years. When the Company is responsible for major maintenance and overhauls, the actual overhaul cost is capitalized and depreciated over the estimated useful life of the overhaul, generally between 2 and 5 years. Repairs and maintenance costs are charged to operations as incurred. Each asset’s estimated useful life, residual value, and method of depreciation are reviewed and adjusted, if appropriate, at each year end, or when factors and circumstances suggest a different useful life for the asset. (f) Goodwill Goodwill arising on an acquisition of a business is initially measured at cost, being the excess of the aggregate of the consideration transferred over the net identifiable assets acquired and liabilities assumed. Following initial recognition, goodwill is measured at cost less any accumulated impairment losses. Goodwill allocated to a group of cash generating units (“CGUs”) is reviewed for impairment annually, or when there is an indication that a related group of CGUs may be impaired. Impairment is determined by assessing the recoverable amount of the group of CGUs to which the goodwill relates. Where the recoverable amount of the group of CGUs is less than the carrying amount of the CGUs and related goodwill, an impairment loss is recognized in the consolidated statements of earnings. Impairment losses on goodwill are not reversed. (g) Intangible Assets Intangible assets are carried at cost less accumulated amortization and any accumulated impairment losses. Intangible assets with a finite life are amortized on a straight-line basis over management’s best estimate of their expected useful lives. The amortization charge is included in selling and administrative expenses in the consolidated statements of earnings. The expected useful lives and amortization method are reviewed on an annual basis with any change in the useful life or pattern of consumption adjusted at year end. Intangible assets are tested for impairment whenever there is an indication that the asset may be impaired. Acquired identifiable intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. Customer relationships, software, and other intangible assets have an estimated useful life range of 3 to 8 years. (h) Impairment of Non-Financial At least annually, the Company reviews the carrying amounts of its tangible and intangible assets with finite lives to assess whether there is an indication that those assets may be impaired. If any such indication exists, the Company makes an estimate of the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s fair value less costs to sell and its value-in-use. value-in-use, pre-tax If the recoverable amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount. A corresponding impairment loss is recognized in the consolidated statements of earnings. Where an impairment loss subsequently reverses, the carrying amount of the asset is increased to the revised estimate of its recoverable amount, but only to the extent that the increased carrying amount does not exceed the original carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Any impairment reversal is recognized in the consolidated statements of earnings. (i) Inventories Inventories are valued at the lower of cost and net realizable value. Serialized inventory is determined on a first-in first-out Non-serialized Cost of equipment, repair and distribution parts, and direct materials, include purchase costs and costs incurred in bringing each product to its present location and condition. Cost of work-in-progress work-in-progress projects that will be accounted for as finance leases. Once the project is completed and enters service the costs will be reclassified to cost of goods sold. Cost of inventories includes the transfer from accumulated other comprehensive income of gains and losses on qualifying cash flow hedges in respect of the purchase of inventory. Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs necessary to make the sale. Inventories are written down to net realizable value when the cost of inventories is estimated to be unrecoverable due to obsolescence, damage, or declining selling prices. Inventories are not written down below cost if the finished products in which they will be incorporated are expected to be sold at or above cost. When circumstances that previously caused inventories to be written down below cost no longer exist or when there is clear evidence of an increase in selling prices, the amount of the write down previously recorded is reversed. (j) Trade Receivables Trade receivables are recognized and carried at original invoice amount less an allowance for any amounts estimated to be uncollectible. The Company calculates an expected credit loss based on historical experience of bad debts and specific provisions created when there is objective evidence that the collection of the full amount of a receivable is no longer probable under the terms of the original invoice. The amount of this allowance represents management’s best estimate of expected credit losses. Trade receivables are derecognized when they are assessed as uncollectible. (k) Cash Cash includes cash and cash equivalents, which are defined as highly liquid investments with original maturities of three months or less. (l) Provisions Provisions are recognized when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. (m) Onerous Contracts A provision for onerous contracts is recognized when the expected benefits to be derived by the Company from a contract are lower than the unavoidable cost of meeting its obligations under the contract. The provision is measured at the present value of the lower of the expected cost of terminating the contract and the expected net cost of continuing with the contract. Before a provision is established, the Company recognizes any impairment loss on the assets associated with that contract. (n) Employee Future Benefits The Company sponsors various defined contribution pension plans, which cover substantially all employees and are funded in accordance with applicable plan and regulatory requirements. Regular contributions are made by the Company to the employees’ individual accounts, which are administered by a plan trustee, in accordance with the plan document. The actual cost of providing benefits through defined contribution pension and the 401(k) matched savings plans is charged to earnings in the period in respect of which contributions become payable. (o) Share-Based Payments Equity-Settled Share-Based Payments The Company offers a Stock Option Plan to key employees, measured at the fair value of the equity instrument at the grant date. Details regarding the determination of the fair value of equity-settled share-based transactions are set out in Note 24. The fair value of equity-settled share-based payments is expensed over a five-year vesting period with a corresponding increase in equity. Stock options have a seven-year expiry and are exercisable at the designated common share price, which is determined by the average of the market price of the Company’s shares on the five days preceding the date of the grant. The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Company’s best estimate of the number of equity instruments that will ultimately vest. Cash-Settled Share-Based Payments The Company offers Deferred Share Unit (“DSU”), Performance Share Unit (“PSU”), Restricted Share Unit (“RSU”), and Cash Performance Target (“CPT”) plans to certain employees. The Company also offers the DSU plan to non-employee The Company also offers a Phantom Share Entitlement (“PSE”) plan to certain employees of affiliates located in Australia and the UAE. PSEs are measured at the fair value of the equity instrument at the grant date and expensed over a five-year vesting period and expire on the seventh anniversary. The exercise price of each PSE equals the average of the market price of the Company’s shares on the five days preceding the date of the grant. At the end of each reporting period until the liability is settled, and at the date of settlement, the fair value of the liability is remeasured, with changes in fair value recognized in the consolidated statements of earnings. The award entitlements for increases in the share trading value of the Company are to be paid to the recipient in cash upon exercise. (p) Leases Company as a Lessee A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether: • The contract involves the use of an identified asset, either explicitly or implicitly, and whether the supplier has a substantive substitution right for the asset; • The Company has the right to obtain substantially all the economic benefits from the use of the asset throughout the period; and • The Company has the right to direct the use of the identified asset. The Company determines if a contractual arrangement is a lease at the inception of the contract term. The Company has identified leases for the following asset types: land and buildings (including manufacturing facilities, office space, and rental accommodations) and equipment (including vehicles, office equipment, and shop equipment). The Company recognizes a right-of-use The right-of-use incurred and an estimate of costs to decommission the underlying asset, less any lease incentives received. The right-of-use The lease liability is initially measured at the present value of remaining lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Lease payments included in the measurement of the lease liability include fixed payments, variable lease payments that depend on an index or rate, amounts expected to be payable under a residual value guarantee, and amounts owing under purchase or termination options, if the Company is reasonably certain to exercise these options. If the lease contains an extension option that the Company is reasonably certain to exercise, all payments in the renewal period are also included in determining the lease liability. The lease liability is measured at amortized cost using the effective interest method. The amount of the liability is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension, or termination option. When the lease liability is remeasured, a corresponding adjustment is made to the carrying value of the right-of-use right-of-use The Company has elected not to recognize right-of-use low-value non-lease right-of-use Company as a Lessor Leases in which the Company is the lessor are assessed upon commencement and are classified as either an operating lease or a finance lease. An operating lease does not transfer substantially all the risks and rewards of the leased asset to the customer. Lease payments from operating leases are recorded as income on a straight-line basis over the life of the lease. A finance lease exists when the terms of the lease transfer substantially all the risks and rewards incidental to ownership of the leased asset to the lessee. Amounts due from lessees under finance leases are recorded as finance lease receivables. Finance leases are initially recognized at amounts equal to the net investment in the lease, determined to be the fair value of the underlying asset, or, if lower, the present value of the lease payments discounted using a market rate of interest. Payments that are part of the leasing arrangement are divided between a reduction in the finance lease receivable and finance lease income. Finance lease income is recognized to produce a constant rate of return on the Company’s investment in the lease and is included in revenues. (q) Revenue Recognition Revenue is recognized as the Company satisfies its performance obligations by transferring promised goods or services to customers, regardless of when payment is received. Revenue is measured at the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties, and may include fixed amounts, variable amounts, or both. Variable amounts are recorded using either the “expected value approach” or the “most likely outcome approach”, as determined upon initial recognition of the contract, and are reassessed at each reporting period. The expected value approach measures variable consideration by probability weighting all the potential outcomes. The most likely outcome approach measures variable consideration as management’s best estimate of the variable component. In estimating variable consideration, the Company reviews any potential for returns, refunds, and other similar obligations. For contracts containing multiple performance obligations, the amount of consideration to which the Company expects to be entitled is allocated to individual performance obligations proportionately based on the stand-alone selling price. Engineered Systems Revenue from the supply of equipment systems – contracts typically involving engineering, design, manufacture, installation, and start-up percentage-of-completion For Engineered Systems contracts, the Company generally requires customers to pay based on milestones as manufacturing progresses. These milestones are generally structured to keep the Company cash flow positive. Contracts are also generally structured to ensure the Company is made whole for costs incurred in the event of cancellation of a contract. Revenue from contracts that have been classified as finance leases for newly built equipment is recorded as Engineered Systems revenue. Upon commencement of the new lease, the Company recognizes revenue, based on the fair value of the underlying assets, and cost of goods sold, determined to be the net book value of those assets, in the consolidated statements of earnings. The finance lease interest portion will be recognized in the Energy Infrastructure product line over the lease term. Service Service revenues include the sales of parts and equipment, as well as the servicing and maintenance of equipment. For the sale of parts and equipment, revenue is recognized when the transfer of control passes, which is typically at the point of shipping. For servicing and maintenance of equipment, revenue is recognized on a straight-line basis based on performance of the contracted-upon service. Revenue from long-term service contracts is recognized on a stage of completion basis proportionate to the service work that has been performed based on parts and labour service provided. Payments are typically required on a monthly basis or as work is performed, with no unusual payment terms. At the completion of the contract, any remaining profit on the contract is recognized as revenue. Any expected losses on such projects are charged to operations when determined. Long-term service contracts include scheduled milestone maintenance, corrective or crash maintenance, the supply of parts, and the operation of equipment. Energy Infrastructure (formerly Rentals) Revenue from equipment rentals is recognized in accordance with the terms of the relevant agreement with the customer on a straight-line basis over the term of the agreement. Payments are typically required on a monthly basis with no unusual payment terms. Certain rental contracts contain an option for the customer to purchase the equipment at the end of the rental period. Should the customer exercise this option to purchase, revenue from the sale of the equipment is recognized directly in the consolidated statements of earnings. Revenue from contracts that have been classified as finance leases related to existing or pre-owned Company recognizes revenue and a finance lease receivable equal to the net investment in the lease. Finance income is recognized in Energy Infrastructure revenue reflecting a constant periodic rate of return on the Company’s net investment in the lease over the lease term. Practical Expedients The Company has elected to use the practical expedients in IFRS 15 Revenue from contracts with customers (r) Financial Instruments Financial instruments are measured at fair value on initial recognition of the instrument, plus or minus transaction costs that are directly attributable to the acquisition or issue of the financial asset or financial liability. For the purposes of measuring financial assets after initial recognition, the Company classifies financial assets as either amortized cost, fair value through other comprehensive income (“FVOCI”) or fair value through profit or loss (“FVTPL”), based on the contractual cash flow characteristics and the Company’s business model for managing the financial asset. For the purposes of measuring financial liabilities after initial recognition, the Company classifies all financial liabilities as amortized cost, except certain financial liabilities, such as derivatives, which are classified as FVTPL. Preferred shares included as long-term receivables in Other assets were recorded at fair value at inception and are subsequently measured at amortized cost. The Company primarily applies the market approach for recurring fair value measurements. Three levels of inputs may be used to measure fair value: • Level 1: Fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities. Active markets are those in which transactions occur in sufficient frequency and volume to provide pricing information on an on-going • Level 2: Fair value measurements are those derived from inputs, other than quoted prices included in Level 1, that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and • Level 3: Fair value measurements are those derived from inputs for the asset or liability that are not based on observable market data (unobservable inputs). In these instances, internally developed methodologies are used to determine fair value. The level in the fair value hierarchy within which the fair value measurement is categorized in its entirety is determined on the basis of the lowest level input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability and may affect placement within. The Company has made the following classifications: • Cash and cash equivalents are measured at fair value through profit or loss. Gains and losses resulting from the periodic revaluation are recorded in the consolidated statements of earnings; • Accounts receivable and preferred shares are recorded at amortized cost using the effective interest rate method; and • Accounts payable, accrued liabilities, and long-term debt are recorded at amortized cost using the effective interest rate method. Transaction costs are expensed as incurred for financial instruments classified or designated as FVTPL. Transaction costs related to other financial liabilities are added to the value of the instrument at acquisition and taken into the consolidated statements of earnings using the effective interest rate method. (s) Derivative Financial Instruments and Hedge Accounting The Company formally documents its risk management objectives and strategies to manage exposures to fluctuations in foreign currency exchange rates and interest rates. The risk management policy permits the use of certain derivative financial instruments, including forward foreign exchange contracts and interest rate swaps, to manage these fluctuations. The Company does not enter into derivative financial agreements for speculative purposes. Derivative financial instruments are measured at their fair value upon initial recognition and are remeasured to their fair value at the end of each reporting period. The fair value of quoted derivatives is equal to their positive or negative market value. Derivatives are carried as assets when the fair value is positive and as liabilities when the fair value is negative. The Company elected to apply hedge accounting for foreign exchange forward contracts for anticipated transactions. These are designated as cash flow hedges. For cash flow hedges, fair value changes of the effective portion of the hedging instrument are recognized in accumulated other comprehensive income, net of taxes. The ineffective portion of the fair value changes is recognized in the consolidated statements of earnings. Amounts charged to accumulated other comprehensive income are reclassified to the consolidated statements of earnings when the hedged transaction affects the consolidated statements of earnings. The Company’s U.S. dollar denominated long-term debt has been designated as a hedge of net investment in self-sustaining foreign operations. As a result, a portion of unrealized foreign exchange gains and losses on the U.S. dollar denominated long-term debt are included in the cumulative translation account in other comprehensive income. On an ongoing basis, an assessment is made as to whether the designated derivative financial instruments continue to be effective in offsetting changes in cash flows of the hedged transactions. (t) Income Taxes Income tax expense represents the sum of current income tax and deferred tax. Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. Taxable earnings differ from earnings as reported in the consolidated statements of earnings as it excludes temporary and permanent differences. The Company’s current tax assets and liabilities are calculated by using tax rates that have been enacted or substantively enacted at the reporting date. Deferred income tax is recognized on all temporary differences at the reporting date based on the difference between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable profit, with the following exceptions: • Where the temporary difference arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss; • In respect of taxable temporary differences associated with investments in subsidiaries, associates and joint ventures, where the timing of the reversal of the temporary difference can be controlled and it is probable that the temporary difference will not reverse in the foreseeable future; and • Deferred income tax assets are recognized only to the extent that it is probable that a taxable profit will be available against which the deductible temporary differences, carried forward tax credits or tax losses can be utilized. The carrying amount of deferred income tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax assets to be utilized. Unrecognized deferred income tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered. Deferred income tax assets and liabilities are measured on an undiscounted basis at the tax rates that are expected to apply when the asset is realized or the liability is settled, based on tax rates and tax laws enacted or substantively enacted at the reporting date. Current and deferred income taxes are charged or credited directly to equity if it relates to items that are credited or charged to equity in the same period. Otherwise, income tax is recognized in the consolidated statements of earnings. In accordance with IAS 12 Income taxes non-monetary (u) Earnings Per Share Basic earnings per share is calculated by dividing the net earnings for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by adjusting the weighted average number of common shares outstanding for dilutive common shares related to the Company’s equity share-based compensation plan. (v) Finance Income and Costs Finance income comprises interest income on funds invested. Finance income is recognized as it accrues in profit or loss, using the effective interest rate method. Finance costs comprise interest expense on borrowings and interest incurred on lease liabilities. (w) Government Grants Government grants are recorded as a reduction in cost of goods sold and selling and administrative expense within the consolidated statements of earnings in accordance with where the associated expense was recognized. Government grants are recognized when there is reasonable assurance that the grant will be received, and all related conditions are complied with.

Changes In Accounting Policies	NOTE 4. CHANGES IN ACCOUNTING POLICIES IFRS 3 Business Combinations (“IFRS 3”) Effective January 1, 2020, the definition of a business was amended under IFRS 3. Under the amended definition, to be considered a business an acquisition must include an input and a substantive process that together significantly contribute to the ability to create outputs. The new guidance provides a framework to evaluate when an input and a substantive process are present. Under the prior definition, IFRS 3 stated that a business need not include all of the inputs or processes that the seller used in operating that business “ if market participants are capable of acquiring the business and continuing to produce outputs, for example, by integrating the business with their own inputs and processes This amendment will be applied prospectively to future acquisitions. While there are no immediate impacts resulting from this amendment, this change will likely result in more acquisitions being accounted for as asset acquisitions. Application of the change could also affect the accounting for disposal transactions. The Company applied the amendments beginning January 1, 2020, with no changes to the Company’s consolidated financial statements.

Significant Accounting Estimates and Judgment	NOTE 5. SIGNIFICANT ACCOUNTING ESTIMATES AND JUDGMENT The timely preparation of financial statements requires that management make estimates and assumptions and use judgment. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Uncertainty about these assumptions and estimates could however result in outcomes that require a material adjustment to the carrying amount of the asset or liability affected in future periods. In the process of applying the Company’s accounting policies, management has made the following judgments, estimates and assumptions which have a significant effect on the amounts recognized in the consolidated financial statements: Revenue Recognition – Performance Obligation Satisfied Over Time The Company reflects revenues relating to performance obligations satisfied over time using the percentage-of-completion percentage-of-completion percentage-of-completion Certain contracts also include aspects of variable consideration, such as liquidated damages on project delays. For these contracts, management must make estimations as to the likelihood of the variable consideration being recognized or constrained, based on the status of each project, the potential value of variable consideration, communication received from the customer, and other factors. Enerflex continues to monitor these factors. Changes in estimated cost or revenue associated with a project, including variable consideration, could result in material changes to revenue and gross margin recognized on certain projects. Revenue Recognition – Performance Obligation Satisfied at a Point in Time The Company reflects revenues relating to performance obligations satisfied at a point in time when control – indicated by transfer of the legal title, physical possession, significant risks and rewards of ownership, or any combination of these indicators – is transferred to the customer. Provisions for Warranty Provisions set aside for warranty exposures either relate to amounts provided systematically based on historical experience under contractual warranty obligations or specific provisions created in respect of individual customer issues undergoing commercial resolution and negotiation. Amounts set aside represent management’s best estimate of the likely settlement and the timing of any resolution with the relevant customer. Business Acquisitions In a business acquisition, the Company may acquire assets and assume certain liabilities of an acquired entity. Estimates are made as to the fair value of property, plant and equipment, intangible assets, and goodwill, among other items. In certain circumstances, such as the valuation of property, plant and equipment and intangible assets acquired, the Company relies on independent third-party valuators. The determination of these fair values involves a variety of assumptions, including revenue growth rates, projected cash flows, discount rates, and earnings multiples. Property, Plant and Equipment and Rental Equipment Property, plant and equipment and rental equipment is stated at cost less accumulated depreciation and any impairment losses. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of property, plant and equipment and rental equipment is reviewed on an annual basis. Assessing the reasonableness of the estimated useful lives of property, plant and equipment and rental equipment requires judgment and is based on currently available information. Property, plant and equipment and rental equipment is also reviewed for potential impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Changes in circumstances, such as technological advances and changes to business strategy can result in actual useful lives differing significantly from estimates. The assumptions used, including rates and methodologies, are reviewed on an ongoing basis to ensure they continue to be appropriate. Revisions to the estimated useful lives of property, plant and equipment and rental equipment constitutes a change in accounting estimate and are applied prospectively. Right-of-Use The Company determines the right-of-use right-of-use Finance Lease Receivables In calculating the value of the Company’s finance lease receivables, the Company is required to determine the fair value of the underlying assets included in the finance lease transaction, or, if lower, the present value of the lease payments discounted using a market rate of interest. The fair value of the underlying assets should reflect the amount that the Company would otherwise recognize on a sale of those assets. Allowance for Doubtful Accounts Amounts included in allowance for doubtful accounts reflect the full lifetime expected credit losses for trade receivables. The Company determines allowances based on management’s best estimate of future expected credit losses, considering historical default rates, current economic conditions, and forecasts of future economic conditions. Future economic conditions, especially around the oil and gas industry, may have a significant impact on the collectability of trade receivables from customers and the corresponding expected credit losses. Management has implemented additional monitoring processes in assessing the creditworthiness of customers and believes the current provision appropriately reflects the best estimate of its future expected credit losses. Significant or unanticipated changes in economic conditions could impact the magnitude of future expected credit losses. Impairment of Inventories The Company regularly reviews the nature and quantities of inventory on hand and evaluates the net realizable value of items based on historical usage patterns, known changes to equipment or processes, and customer demand for specific products. Significant or unanticipated changes in business conditions could impact the magnitude and timing of impairment recognized. Impairment of Non-Financial Impairment exists when the carrying value of an asset or group of assets exceeds its recoverable amount, which is the higher of its fair value less costs to sell and its value-in-use. value-in-use Impairment of Goodwill The Company tests goodwill for impairment at least on an annual basis, or when there is any indication that goodwill may be impaired. This requires an estimation of the value-in-use value-in-use Income Taxes Uncertainties exist with respect to the interpretation of complex tax regulations and the amount and timing of future taxable income. Given the wide range of international business relationships and the long-term nature and complexity of existing contractual agreements, differences arising between the actual results and the assumptions made, or future changes to such assumptions, could necessitate future adjustments to taxable income. The Company establishes provisions, based on reasonable estimates, for possible consequences of audits by the tax authorities of the respective countries in which it operates. The amount of such provisions is based on various factors, such as experience of previous tax audits and differing interpretations of tax regulations by the taxable entity and the responsible tax authority. Such differences of interpretation may arise on a wide variety of issues depending on the conditions prevailing in the respective company’s domicile. Deferred tax assets are recognized for all unused tax losses, carried forward tax credits or other deductible temporary differences to the extent that it is probable that taxable profit will be available against which these deferred tax assets can be utilized. Significant judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the timing of reversal, expiry of losses and the level of future taxable profits together with future tax planning strategies. The basis for this estimate is management’s cash flow projections. To the extent the Company determines the recoverability of deferred tax assets is unlikely, the deferred tax asset is not recognized. Management regularly assesses the unrecognized deferred tax asset to determine what portion can be recognized in response to changing economic conditions or recent events. Share-Based Compensation The Company employs the fair value method of accounting for stock options and phantom share entitlement. The determination of the share-based compensation expense for stock options and phantom share entitlement requires the use of estimates and assumptions based on exercise prices, market conditions, vesting criteria, length of employment, and past experiences of the Company. Changes in these estimates and future events could alter the determination of the provision for such compensation. Details concerning the assumptions used are described in Note 24.

Goodwill and Impairment Review of Goodwill	NOTE 14.

At December 31, 2021, the Company determined that there were no indicators of impairment, and performed an annual assessment comparing the carrying amount and recoverable amount for each segment in accordance with IAS 36.10(b). In assessing whether goodwill has been impaired, the carrying amount of the segment (including goodwill) is compared with its recoverable amount. The recoverable amount is the higher of the fair value less costs to sell and value-in-use. The recoverable amounts for the segments have been determined based on value-in-use value-in-use. Key Assumptions Used in Value-In-Use The Company completed its annual assessment for goodwill impairment and determined that the recoverable amount for the USA, Rest of World, and Canada segments exceeded the carrying amount using a 9.4 percent (December 31, 2020 – 9.6 percent), percent (December 31, 2020 – percent), and percent) post-tax The estimation of value-in-use • Earnings Before Finance Costs and Taxes: Management has made estimates relating to the amount and timing of revenue recognition for projects included in backlog, and the assessment of the likelihood of maintaining and growing market share. For each ten percent change in earnings before finance costs and taxes, the impact on the value-in-use • Discount Rate: Management determines a discount rate for each segment based on the estimated weighted average cost of capital of the Company, using the five-year average of the Company’s peer group debt to total enterprise value, adjusted for a number of risk factors specific to each segment. This discount rate has been calculated using an estimated risk-free rate of return adjusted for the Company’s estimated equity market risk premium, the Company’s cost of debt, and the tax rate in the local jurisdiction. For each one percent change in the discount rate, the impact on the value-in-use Management will continue to assess the long-term projected

These Notes consist of $105.0 million U.S. dollar and $15.0 million Canadian dollar maturing December 15, 2024 bearing an interest rate of 4.67 percent and 4.50 percent respectively, and $70.0 million U.S. dollar and $30.0 million Canadian dollar maturing December 15, 2027 bearing an interest rate of 4.87 percent and 4.79 percent respectively. During the third quarter of 2021, Enerflex successfully extended the maturity date for $660.0 million of $725.0 million in commitments to its amended and restated syndicated revolving credit facility (“Bank Facility”) to June 30, 2025 (the “Maturity Date”). The maturity date for the other $65.0 million in commitments to the Bank Facility remains June 30, 2023. In addition, the Bank Facility may be increased by $150.0 million at the request of the Company, subject to the lenders’ consent. There are no required or scheduled repayment of principal until the maturity date of the Bank Facility. Drawings on the Bank Facility are available by way of Prime Rate loans, U.S. Base Rate loans, London Interbank Offered Rate (“LIBOR”) loans, and Bankers’ Acceptance notes. The Company may also draw on the Bank Facility through bank overdrafts in either Canadian or U.S. dollars and issue letters of credit under the Bank Facility. Pursuant to the terms and conditions of the Bank Facility, a margin is applied to drawings on the Bank Facility in addition to the quoted interest rate. The margin is established in basis points and is based on a consolidated net debt to earnings before finance costs, income taxes, depreciation and amortization (“EBITDA”) ratio. The margin is adjusted effective the first day of the third month following the end of each fiscal quarter based on the above ratio. The Bank Facility is unsecured and ranks pari passu with the Notes. The Company is required to maintain certain covenants on the Bank Facility and the Notes. As at December 31, 2021, the Company was in compliance with these covenants. During the second quarter of 2021, a subsidiary of the Company finalized access to a credit facility, secured by certain assets of the subsidiary, of up to $52.5 million U.S. dollars (the “Asset-Based Facility”). This new credit facility is non-recourse to the Company. Under the terms of the Asset-Based Facility, the Company is required to maintain certain covenants. As at December 31, 2021, the Company was in compliance with these covenants. Pursuant to the terms and conditions of the Asset-Based Facility, a margin is applied to drawings on the Asset-Based Facility in addition to the quoted interest rate. The margin is established as a percentage and is based on a consolidated total funded debt to EBITDA ratio. The composition of the borrowings on the Bank Facility, Asset-Based Facility, and the Company’s Notes is as follows: December 31, 2021 2020 Drawings on Bank Facility $ 30,522 $ 84,369 Drawings on Asset-Based Facility 37,411 — Notes due June 22, 2021 — 40,000 Notes due December 15, 2024 148,119 148,686 Notes due December 15, 2027 118,746 119,124 Deferred transaction costs (3,376 ) (2,467 ) $ 331,422 $ 389,712 Current portion of long-term debt $ — $ 40,000 Non-current 331,422 349,712 $ 331,422 $ 389,712 During the second quarter of 2021, the Company repaid $40.0 million of 6.0 percent senior unsecured notes that were due June 22, 2021.

The weighted average interest rate on the Bank Facility for the year ended December 31, 2021 was 2.1 percent (December 31, 2020 – 2.3 percent). The weighted average interest rate on the Asset-Based Facility for the year ended December 31, 2021 was 3.0 percent (December 31, 2020 – nil ).

A reconciliation of the difference is as follows: Years ended December 31, 2021 2020 2019 Earnings before income taxes $ 38,102 $ 95,559 $ 215,324 Canadian statutory rate 23.8 % 24.4 % 26.5 % Expected income tax provision $ 9,068 $ 23,316 $ 57,061 Add (deduct): Exchange rate effects on tax basis (2,269 ) (4,007 ) 2,125 Earnings taxed in foreign jurisdictions 2,313 (14,505 ) (1,129 ) Revaluation of Canadian deferred tax assets due to change in statutory rate (660 ) 597 5,040 Withholding tax on dividends received from foreign subsidiaries 2,763 — — Amounts not deductible (taxable) for tax purposes 811 2,426 723 Impact of accounting for associates and joint ventures (160 ) (530 ) (575 ) Change in recognized deferred tax assets 44,704 — — Other (13 ) 5 (49 ) Income tax expense from continuing operations $ 56,557 $ 7,302 $ 63,196 The applicable statutory tax rate is the aggregate of the Canadian federal income tax rate of 15.0 percent (2020 – 15.0 percent; 2019 – 15.0 percent) and provincial income tax rates of 8.8 percent (2020 – 9.4 percent; 2019 – 11.5 percent). During the fourth quarter of 2020, lower Alberta corporate income tax rates became substantively enacted. The Alberta corporate income tax rates are 11.5 percent for 2019, 8.99 percent for 2020, and 8.0 percent thereafter. The Company’s effective tax rate is subject to fluctuations in the Argentine peso and Mexican peso exchange rate against the U.S. dollar. Since the Company holds significant rental assets in Argentina and Mexico, the tax base of these assets is denominated in Argentine peso and Mexican peso, respectively. The functional currency is, however, the U.S. dollar and as a result, the related local currency tax bases are revalued periodically to reflect the closing U.S. dollar rate against these currencies. Any movement in the exchange rate results in a corresponding unrealized exchange rate gain or loss being recorded as part of deferred income tax expense or recovery. During periods of large fluctuation or devaluation of the local currency against the U.S. dollar, these amounts may be significant but are unrealized and may reverse in the future. Recognition of these amounts is required by IFRS, even though the revalued tax basis does not generate any cash tax obligation or liability in the future.

During the year ended December 31, 2021, there were no transfers between Level 1 and Level 2 fair value measurements. Fair values are determined using inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. Fair values determined using inputs including forward market rates and credit spreads that are readily observable and reliable, or for which unobservable inputs are determined not to be significant to the fair value, are categorized as Level 2. If there is no active market, fair value is established using valuation techniques, including discounted cash flow models. The inputs to these models are taken from observable market data where possible, including recent arm’s-length Carrying Fair Value Level 1 Level 2 Level 3 Financial Assets Derivative financial instruments $ 294 $ — $ 294 $ — Long-term receivables $ 24,172 $ — $ 27,471 $ — Financial Liabilities Derivative financial instruments $ 180 $ — $ 180 $ — Long-term debt – Notes $ 266,865 $ — $ 280,295 $ — Cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, and other liabilities are reported at amounts approximating their fair values on the consolidated statement of financial position. The fair values approximate the carrying values for these instruments due to their short-term nature. The fair value of derivative financial instruments is measured using the discounted value of the difference between the contract’s value at maturity based on the contracted foreign exchange rate and the contract’s value at maturity based on prevailing exchange rates. The financial institution’s credit risk is also taken into consideration in determining fair value. Long-term debt associated with the Company’s Notes is recorded at amortized cost using the effective interest rate method. The amortized cost of the Notes is equal to the face value as there were no premiums or discounts on the issuance of the debt. Transaction costs associated with the debt were deducted from the debt and are being recognized using the effective interest rate method over the life of the related debt. The fair value of these Notes, determined on a discounted cash flow basis using a weighted average discount rate of 3.5 percent, was $280.3 million at December 31, 2021. Preferred Shares During the third quarter of 2020, the Company accepted preferred shares from a customer in exchange for products and services. The preferred shares were initially recorded at fair value and subsequently measured at amortized cost and recognized as long-term receivables in Other assets. The carrying value and estimated fair value of the preferred shares at December 31, 2021 was $24.2 million and $27.5 million (December 31, 2020 – $22.0 million and $25.7 million). Derivative Financial Instruments and Hedge Accounting Foreign exchange contracts are transacted with financial institutions to hedge foreign currency denominated obligations and cash receipts related to purchases of inventory and sales of products. The following table summarizes the Company’s commitments to buy and sell forei g Notional Maturity Canadian Dollar Denominated Contracts Purchase contracts USD 16,119 January 2022 – June 2022 Sales contracts USD (10,849 ) January 2022 – September 2022 Purchase contracts EUR 1,091 June 2022 Sales contracts EUR (641 ) June 2022 Management estimates that a gain of $0.1 million All hedging relationships are formally documented, including the risk management objective and strategy. On an on-going Risks Arising from Financial Instruments and Risk Management In the normal course of business, the Company is exposed to financial risks that may potentially impact its operating results in any or all of its business segments. The Company employs risk management strategies with a view to mitigating these risks on a cost-effective basis. Derivative financial agreements are used to manage exposure to fluctuations in exchange rates and interest rates. The Company does not enter into derivative financial agreements for speculative purposes. Foreign Currency Translation Exposure In the normal course of operations, the Company is exposed to movements in the U.S. dollar, the Australian dollar, and the Brazilian real. In addition, Enerflex has significant international exposure through export from its Canadian operations, as well as a number of foreign subsidiaries, the most significant of which are located in the United States, Argentina, Brazil, Colombia, Mexico, Bahrain, Oman, the UAE, and Australia. The types of foreign exchange risk and the Company’s related risk management strategies are as follows: Transaction Exposure The Canadian operations of the Company source the majority of its products and major components from the United States. Consequently, reported costs of inventory and the transaction prices charged to customers for equipment and parts are affected by the relative strength of the Canadian dollar. The Company also sells compression and processing packages in foreign currencies, primarily the U.S. dollar. Most of Enerflex’s international orders are manufactured in the United States if the contract is denominated in U.S. dollars. This minimizes the Company’s foreign currency exposure on these contracts. The Company identifies and hedges all significant transactional currency risks. The Company has implemented a hedging policy, applicable primarily to the Canadian domiciled business units, with the objective of securing the Translation Exposure The Company’s earnings from and net investment in foreign subsidiaries are exposed to fluctuations in exchange rates. The currencies with the most significant impact are the U.S. dollar, Australian dollar, and Brazilian real. Monetary assets and liabilities denominated in foreign currencies are translated into Canadian dollars using the exchange rates in effect at the reporting dates. Non-monetary Earnings from foreign operations are translated into Canadian dollars each period at average exchange rates for the period. As a result, fluctuations in the value of the Canadian dollar relative to these other currencies will impact reported net earnings. The following table shows the effect of a five percent weakening of the Canadian dollar against the U.S. dollar, Australian dollar, and Brazilian real on net earnings before tax for the year ended December 31, 2021, all else being equal. A five percent strengthening of the Canadian dollar would have an equal and opposite effect. This sensitivity analysis is provided as an indicative range in a volatile currency en v Canadian dollar weakens by 5 percent USD AUD BRL Earnings before income taxes $ 1,776 $ (90 ) $ 167 Sensitivity Analysis The following sensitivity analysis is intended to illustrate the sensitivity to changes in foreign exchange rates Canadian dollar weakens by 5 percent USD AUD BRL Financial instruments held in foreign operations Other comprehensive income $ 14,019 $ 908 $ 221 Financial instruments held in Canadian operations Earnings before income taxes $ (9,633 ) $ — $ — The movement in net earnings before tax in Canadian operations is a result of a change in the fair values of financial instruments. The majority of these financial instruments are hedged. Interest Rate Risk The Company’s liabilities include long-term debt that is subject to fluctuations in interest rates. The Company’s Notes outstanding at December 31, 2021 include interest rates that are fixed and therefore the related interest expense will not be impacted by fluctuations in interest rates. The Company’s Bank and Asset-Based Facilities, however, is subject to changes in market interest rates. For each one percent change in the rate of interest on the Bank and Asset-Based Facilities, the change in annual interest expense would be $0.7 million. All interest charges are recorded on the consolidated statements of earnings as finance costs. Credit Risk Financial instruments that potentially subject the Company to credit risk consist of cash equivalents, accounts receivable, net investment in finance lease, and derivative financial instruments. The Company has accounts receivable from clients engaged in various industries. These specific industries may be affected by economic factors that may impact accounts receivable. Credit quality of the customer is assessed based on an extensive credit rating scorecard and individual credit limits are defined in accordance with this assessment. Credit is extended based on an evaluation of the customer’s financial condition and, generally, advance payment is not required. Outstanding customer receivables are regularly monitored and an allowance for doubtful accounts is established based expected credit losses. The Company evaluates the concentration of risk at December 31, 2021 with respect to trade receivables as low, as its customers are located in several jurisdictions and industries and operate in largely independent markets. At December 31, 2021, the Company had no individual customers which accounted to more than 10 percent of its revenue or receivables (December 31, 2020 – the Company had no individual customers which accounted to more than 10 percent of its revenue or receivables). The maximum exposure to credit risk at the reporting date is the carrying value of each class of financial assets disclosed in this note. The Company does not hold collateral as security . The credit risk associated with the net investment in finance leases arises from the possibility that the counterparties may default on their obligations. In order to minimize this risk, the Company enters into finance lease transactions only in select circumstances. Close contact is maintained with the customer over the duration of the lease to ensure visibility to issues as and if they arise. The credit risk associated with derivative financial instruments arises from the possibility that the counterparties may default on their obligations. In order to minimize this risk, the Company enters into derivative transactions only with highly-rated financial institutions. Liquidity Risk Liquidity risk is the risk that the Company may encounter difficulties in meeting obligations associated with financial liabilities. In managing liquidity risk, the Company has access to a significant portion of its Bank and Asset-Based Facilities for future drawings to meet the Company’s future growth targets and to pay its obligations as they come due. As at December 31, 2021, the Company held cash and cash equivalents of $172.8 million and had drawn $67.9 million against the Bank and Asset-Based Facilities, leaving it with access to $681.5 million for future drawings. The Company continues to meet the covenant requirements of its funded debt, including the Bank Facility and Notes, with a bank-adjusted net debt to EBITDA ratio of 1.0:1 3:1 8:1 3:1 12-month A liquidity analysis of the Company’s financial instruments has been completed on a maturity basis. The following table outlines the cash flows, including interest associated with the maturity of the Company’s financial liabilities, as at December 31, 2021: Less than 3 months Greater than Total Derivative financial instruments Foreign currency forward contracts $ 124 $ 56 $ — $ 180 Accounts payable and accrued liabilities 240,747 — — 240,747 Long-term debt – Bank Facility — — 30,522 30,522 Long-term debt – Asset-Based Facility — — 37,411 37,411 Long-term debt – Notes — — 266,865 266,865 Other long-term liabilities — — 15,785 15,785 The Company expects that cash flows from operations in 2022, together with cash and cash equivalents on hand and credit facilities, will be more than sufficient to fund its requirements for investments in working capital and capital assets.

Seasonality	NOTE 33. SEASONALITY The oil and natural gas service sector in Canada and in some parts of the USA has a distinct seasonal trend in activity levels which results from well-site access and drilling pattern adjustments to take advantage of weather conditions. Generally, Enerflex’s Engineered Systems product line has experienced higher revenues in the fourth quarter of each year while Service and Energy Infrastructure product line revenues have been stable throughout the year. Energy Infrastructure revenues are also impacted by both the Company’s and its customers’ capital investment decisions. The USA and Rest of World segments are not significantly impacted by seasonal variations. Variations from these trends usually occur when hydrocarbon energy fundamentals are either improving or deteriorating.

Investments in Associates and Joint Ventures	(a) Investments in Associates and Joint Ventures The Company uses the equity method to account for its 45 percent investment in Roska DBO Inc. (“Roska DBO”) and its 65 percent investment in a joint venture in Brazil. Under the equity method, the investment is carried on the consolidated statements of financial position at cost plus post acquisition changes in the Company’s share of net assets of the associate or joint venture. The consolidated statements of earnings reflect the Company’s share of the results of operations of associates and joint ventures. Unrealized gains and losses resulting from transactions between the Company and associates are eliminated to the extent of the interest in the associate or joint venture. The Company’s share of profits from associates and joint ventures is shown on the face of the consolidated statements of earnings. This is the profit attributable to equity holders of the associate and joint venture partners and, therefore, is profit after tax and non-controlling
Foreign Currency Translation	(b) Foreign Currency Translation In the accounts of individual subsidiaries, transactions in currencies other than the Company’s functional currency are recorded at the prevailing rate of exchange at the date of the transaction. At year end, monetary assets and liabilities denominated in foreign currencies are translated at the rates of exchange prevailing at that date. Non-monetary Non-monetary The assets and liabilities on the statements of financial position of foreign subsidiaries are translated into Canadian dollars at the rates of exchange prevailing at the reporting date. The statements of earnings of foreign subsidiaries are translated at average exchange rates for the reporting period. Exchange differences arising on the translation of net assets are taken to accumulated other comprehensive income. All foreign exchange gains and losses are taken to the consolidated statements of earnings with the exception of exchange differences arising on monetary assets and liabilities that form part of the Company’s net investment in subsidiaries. These are taken directly to other comprehensive income until the disposal of the foreign subsidiary at which time the unrealized gain or loss is recognized in the consolidated statements of earnings. On the disposal of a foreign subsidiary, accumulated exchange differences are recognized in the consolidated statements of earnings as a component of the gain or loss on disposal.
Business Combinations	(c) Business Combinations Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at fair value on the date of the acquisition. Acquisition costs incurred are expensed and included in selling and administrative expenses, except for those associated with the issuance of debt, which are included in the initial carrying amount of the liability. Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred over the net identifiable assets acquired and liabilities assumed.
Property, Plant and Equipment	(d) Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation and any accumulated impairment losses. Cost comprises the purchase price or construction cost and any costs directly attributable to making the asset capable of operating as intended. Depreciation is provided using the straight-line method over the estimated useful lives of the various classes of assets and commences when the assets are ready for intended use. Asset Class Estimated Useful Life Range Buildings 5 to 20 years Equipment 2 to 20 years Major renewals and improvements are capitalized when they are expected to provide future economic benefit. When significant components of property, plant and equipment are required to be replaced at intervals, the Company derecognizes the replaced part, and recognizes the new part with its own associated useful life and depreciation. No depreciation is charged on land or assets under construction. Repairs and maintenance costs are charged to operations as incurred. The carrying amount of an item of property, plant and equipment is derecognized on disposal or when no future economic benefits are expected from its use or disposal. The gain or loss arising from derecognition of property, plant and equipment is included in the consolidated statements of earnings when the item is derecognized. Each asset’s estimated useful life, residual value, and method of depreciation are reviewed and adjusted, if appropriate, at each year end, or when factors and circumstances suggest a different useful life for the asset.
Rental Equipment	(e) Rental Equipment Rental equipment is stated at cost less accumulated depreciation and any accumulated impairment losses. Depreciation is provided using the straight-line method over the estimated useful lives of the assets, which are generally between 5 and 20 years. When the Company is responsible for major maintenance and overhauls, the actual overhaul cost is capitalized and depreciated over the estimated useful life of the overhaul, generally between 2 and 5 years. Repairs and maintenance costs are charged to operations as incurred. Each asset’s estimated useful life, residual value, and method of depreciation are reviewed and adjusted, if appropriate, at each year end, or when factors and circumstances suggest a different useful life for the asset.
Goodwill	(f) Goodwill Goodwill arising on an acquisition of a business is initially measured at cost, being the excess of the aggregate of the consideration transferred over the net identifiable assets acquired and liabilities assumed. Following initial recognition, goodwill is measured at cost less any accumulated impairment losses. Goodwill allocated to a group of cash generating units (“CGUs”) is reviewed for impairment annually, or when there is an indication that a related group of CGUs may be impaired. Impairment is determined by assessing the recoverable amount of the group of CGUs to which the goodwill relates. Where the recoverable amount of the group of CGUs is less than the carrying amount of the CGUs and related goodwill, an impairment loss is recognized in the consolidated statements of earnings. Impairment losses on goodwill are not reversed.
Intangible Assets	(g) Intangible Assets Intangible assets are carried at cost less accumulated amortization and any accumulated impairment losses. Intangible assets with a finite life are amortized on a straight-line basis over management’s best estimate of their expected useful lives. The amortization charge is included in selling and administrative expenses in the consolidated statements of earnings. The expected useful lives and amortization method are reviewed on an annual basis with any change in the useful life or pattern of consumption adjusted at year end. Intangible assets are tested for impairment whenever there is an indication that the asset may be impaired. Acquired identifiable intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. Customer relationships, software, and other intangible assets have an estimated useful life range of 3 to 8 years.
Impairment of Non-Financial Assets (excluding Goodwill)	(h) Impairment of Non-Financial At least annually, the Company reviews the carrying amounts of its tangible and intangible assets with finite lives to assess whether there is an indication that those assets may be impaired. If any such indication exists, the Company makes an estimate of the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s fair value less costs to sell and its value-in-use. value-in-use, pre-tax If the recoverable amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount. A corresponding impairment loss is recognized in the consolidated statements of earnings. Where an impairment loss subsequently reverses, the carrying amount of the asset is increased to the revised estimate of its recoverable amount, but only to the extent that the increased carrying amount does not exceed the original carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Any impairment reversal is recognized in the consolidated statements of earnings.
Inventories	(i) Inventories Inventories are valued at the lower of cost and net realizable value. Serialized inventory is determined on a first-in first-out Non-serialized Cost of equipment, repair and distribution parts, and direct materials, include purchase costs and costs incurred in bringing each product to its present location and condition. Cost of work-in-progress work-in-progress projects that will be accounted for as finance leases. Once the project is completed and enters service the costs will be reclassified to cost of goods sold. Cost of inventories includes the transfer from accumulated other comprehensive income of gains and losses on qualifying cash flow hedges in respect of the purchase of inventory. Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs necessary to make the sale. Inventories are written down to net realizable value when the cost of inventories is estimated to be unrecoverable due to obsolescence, damage, or declining selling prices. Inventories are not written down below cost if the finished products in which they will be incorporated are expected to be sold at or above cost. When circumstances that previously caused inventories to be written down below cost no longer exist or when there is clear evidence of an increase in selling prices, the amount of the write down previously recorded is reversed.
Trade Receivables	(j) Trade Receivables Trade receivables are recognized and carried at original invoice amount less an allowance for any amounts estimated to be uncollectible. The Company calculates an expected credit loss based on historical experience of bad debts and specific provisions created when there is objective evidence that the collection of the full amount of a receivable is no longer probable under the terms of the original invoice. The amount of this allowance represents management’s best estimate of expected credit losses. Trade receivables are derecognized when they are assessed as uncollectible.
Cash	(k) Cash Cash includes cash and cash equivalents, which are defined as highly liquid investments with original maturities of three months or less.
Provisions	(l) Provisions Provisions are recognized when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation.
Onerous Contracts	(m) Onerous Contracts A provision for onerous contracts is recognized when the expected benefits to be derived by the Company from a contract are lower than the unavoidable cost of meeting its obligations under the contract. The provision is measured at the present value of the lower of the expected cost of terminating the contract and the expected net cost of continuing with the contract. Before a provision is established, the Company recognizes any impairment loss on the assets associated with that contract.
Employee Future Benefits	(n) Employee Future Benefits The Company sponsors various defined contribution pension plans, which cover substantially all employees and are funded in accordance with applicable plan and regulatory requirements. Regular contributions are made by the Company to the employees’ individual accounts, which are administered by a plan trustee, in accordance with the plan document. The actual cost of providing benefits through defined contribution pension and the 401(k) matched savings plans is charged to earnings in the period in respect of which contributions become payable.
Share-Based Payments	(o) Share-Based Payments Equity-Settled Share-Based Payments The Company offers a Stock Option Plan to key employees, measured at the fair value of the equity instrument at the grant date. Details regarding the determination of the fair value of equity-settled share-based transactions are set out in Note 24. The fair value of equity-settled share-based payments is expensed over a five-year vesting period with a corresponding increase in equity. Stock options have a seven-year expiry and are exercisable at the designated common share price, which is determined by the average of the market price of the Company’s shares on the five days preceding the date of the grant. The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Company’s best estimate of the number of equity instruments that will ultimately vest. Cash-Settled Share-Based Payments The Company offers Deferred Share Unit (“DSU”), Performance Share Unit (“PSU”), Restricted Share Unit (“RSU”), and Cash Performance Target (“CPT”) plans to certain employees. The Company also offers the DSU plan to non-employee The Company also offers a Phantom Share Entitlement (“PSE”) plan to certain employees of affiliates located in Australia and the UAE. PSEs are measured at the fair value of the equity instrument at the grant date and expensed over a five-year vesting period and expire on the seventh anniversary. The exercise price of each PSE equals the average of the market price of the Company’s shares on the five days preceding the date of the grant. At the end of each reporting period until the liability is settled, and at the date of settlement, the fair value of the liability is remeasured, with changes in fair value recognized in the consolidated statements of earnings. The award entitlements for increases in the share trading value of the Company are to be paid to the recipient in cash upon exercise.
Leases	(p) Leases Company as a Lessee A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether: • The contract involves the use of an identified asset, either explicitly or implicitly, and whether the supplier has a substantive substitution right for the asset; • The Company has the right to obtain substantially all the economic benefits from the use of the asset throughout the period; and • The Company has the right to direct the use of the identified asset. The Company determines if a contractual arrangement is a lease at the inception of the contract term. The Company has identified leases for the following asset types: land and buildings (including manufacturing facilities, office space, and rental accommodations) and equipment (including vehicles, office equipment, and shop equipment). The Company recognizes a right-of-use The right-of-use incurred and an estimate of costs to decommission the underlying asset, less any lease incentives received. The right-of-use The lease liability is initially measured at the present value of remaining lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Lease payments included in the measurement of the lease liability include fixed payments, variable lease payments that depend on an index or rate, amounts expected to be payable under a residual value guarantee, and amounts owing under purchase or termination options, if the Company is reasonably certain to exercise these options. If the lease contains an extension option that the Company is reasonably certain to exercise, all payments in the renewal period are also included in determining the lease liability. The lease liability is measured at amortized cost using the effective interest method. The amount of the liability is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension, or termination option. When the lease liability is remeasured, a corresponding adjustment is made to the carrying value of the right-of-use right-of-use The Company has elected not to recognize right-of-use low-value non-lease right-of-use Company as a Lessor Leases in which the Company is the lessor are assessed upon commencement and are classified as either an operating lease or a finance lease. An operating lease does not transfer substantially all the risks and rewards of the leased asset to the customer. Lease payments from operating leases are recorded as income on a straight-line basis over the life of the lease. A finance lease exists when the terms of the lease transfer substantially all the risks and rewards incidental to ownership of the leased asset to the lessee. Amounts due from lessees under finance leases are recorded as finance lease receivables. Finance leases are initially recognized at amounts equal to the net investment in the lease, determined to be the fair value of the underlying asset, or, if lower, the present value of the lease payments discounted using a market rate of interest. Payments that are part of the leasing arrangement are divided between a reduction in the finance lease receivable and finance lease income. Finance lease income is recognized to produce a constant rate of return on the Company’s investment in the lease and is included in revenues.
Revenue Recognition	(q) Revenue Recognition Revenue is recognized as the Company satisfies its performance obligations by transferring promised goods or services to customers, regardless of when payment is received. Revenue is measured at the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties, and may include fixed amounts, variable amounts, or both. Variable amounts are recorded using either the “expected value approach” or the “most likely outcome approach”, as determined upon initial recognition of the contract, and are reassessed at each reporting period. The expected value approach measures variable consideration by probability weighting all the potential outcomes. The most likely outcome approach measures variable consideration as management’s best estimate of the variable component. In estimating variable consideration, the Company reviews any potential for returns, refunds, and other similar obligations. For contracts containing multiple performance obligations, the amount of consideration to which the Company expects to be entitled is allocated to individual performance obligations proportionately based on the stand-alone selling price. Engineered Systems Revenue from the supply of equipment systems – contracts typically involving engineering, design, manufacture, installation, and start-up percentage-of-completion For Engineered Systems contracts, the Company generally requires customers to pay based on milestones as manufacturing progresses. These milestones are generally structured to keep the Company cash flow positive. Contracts are also generally structured to ensure the Company is made whole for costs incurred in the event of cancellation of a contract. Revenue from contracts that have been classified as finance leases for newly built equipment is recorded as Engineered Systems revenue. Upon commencement of the new lease, the Company recognizes revenue, based on the fair value of the underlying assets, and cost of goods sold, determined to be the net book value of those assets, in the consolidated statements of earnings. The finance lease interest portion will be recognized in the Energy Infrastructure product line over the lease term. Service Service revenues include the sales of parts and equipment, as well as the servicing and maintenance of equipment. For the sale of parts and equipment, revenue is recognized when the transfer of control passes, which is typically at the point of shipping. For servicing and maintenance of equipment, revenue is recognized on a straight-line basis based on performance of the contracted-upon service. Revenue from long-term service contracts is recognized on a stage of completion basis proportionate to the service work that has been performed based on parts and labour service provided. Payments are typically required on a monthly basis or as work is performed, with no unusual payment terms. At the completion of the contract, any remaining profit on the contract is recognized as revenue. Any expected losses on such projects are charged to operations when determined. Long-term service contracts include scheduled milestone maintenance, corrective or crash maintenance, the supply of parts, and the operation of equipment. Energy Infrastructure (formerly Rentals) Revenue from equipment rentals is recognized in accordance with the terms of the relevant agreement with the customer on a straight-line basis over the term of the agreement. Payments are typically required on a monthly basis with no unusual payment terms. Certain rental contracts contain an option for the customer to purchase the equipment at the end of the rental period. Should the customer exercise this option to purchase, revenue from the sale of the equipment is recognized directly in the consolidated statements of earnings. Revenue from contracts that have been classified as finance leases related to existing or pre-owned Company recognizes revenue and a finance lease receivable equal to the net investment in the lease. Finance income is recognized in Energy Infrastructure revenue reflecting a constant periodic rate of return on the Company’s net investment in the lease over the lease term. Practical Expedients The Company has elected to use the practical expedients in IFRS 15 Revenue from contracts with customers
Financial Instruments	(r) Financial Instruments Financial instruments are measured at fair value on initial recognition of the instrument, plus or minus transaction costs that are directly attributable to the acquisition or issue of the financial asset or financial liability. For the purposes of measuring financial assets after initial recognition, the Company classifies financial assets as either amortized cost, fair value through other comprehensive income (“FVOCI”) or fair value through profit or loss (“FVTPL”), based on the contractual cash flow characteristics and the Company’s business model for managing the financial asset. For the purposes of measuring financial liabilities after initial recognition, the Company classifies all financial liabilities as amortized cost, except certain financial liabilities, such as derivatives, which are classified as FVTPL. Preferred shares included as long-term receivables in Other assets were recorded at fair value at inception and are subsequently measured at amortized cost. The Company primarily applies the market approach for recurring fair value measurements. Three levels of inputs may be used to measure fair value: • Level 1: Fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities. Active markets are those in which transactions occur in sufficient frequency and volume to provide pricing information on an on-going • Level 2: Fair value measurements are those derived from inputs, other than quoted prices included in Level 1, that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and • Level 3: Fair value measurements are those derived from inputs for the asset or liability that are not based on observable market data (unobservable inputs). In these instances, internally developed methodologies are used to determine fair value. The level in the fair value hierarchy within which the fair value measurement is categorized in its entirety is determined on the basis of the lowest level input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability and may affect placement within. The Company has made the following classifications: • Cash and cash equivalents are measured at fair value through profit or loss. Gains and losses resulting from the periodic revaluation are recorded in the consolidated statements of earnings; • Accounts receivable and preferred shares are recorded at amortized cost using the effective interest rate method; and • Accounts payable, accrued liabilities, and long-term debt are recorded at amortized cost using the effective interest rate method. Transaction costs are expensed as incurred for financial instruments classified or designated as FVTPL. Transaction costs related to other financial liabilities are added to the value of the instrument at acquisition and taken into the consolidated statements of earnings using the effective interest rate method.
Derivative Financial Instruments and Hedge Accounting	(s) Derivative Financial Instruments and Hedge Accounting The Company formally documents its risk management objectives and strategies to manage exposures to fluctuations in foreign currency exchange rates and interest rates. The risk management policy permits the use of certain derivative financial instruments, including forward foreign exchange contracts and interest rate swaps, to manage these fluctuations. The Company does not enter into derivative financial agreements for speculative purposes. Derivative financial instruments are measured at their fair value upon initial recognition and are remeasured to their fair value at the end of each reporting period. The fair value of quoted derivatives is equal to their positive or negative market value. Derivatives are carried as assets when the fair value is positive and as liabilities when the fair value is negative. The Company elected to apply hedge accounting for foreign exchange forward contracts for anticipated transactions. These are designated as cash flow hedges. For cash flow hedges, fair value changes of the effective portion of the hedging instrument are recognized in accumulated other comprehensive income, net of taxes. The ineffective portion of the fair value changes is recognized in the consolidated statements of earnings. Amounts charged to accumulated other comprehensive income are reclassified to the consolidated statements of earnings when the hedged transaction affects the consolidated statements of earnings. The Company’s U.S. dollar denominated long-term debt has been designated as a hedge of net investment in self-sustaining foreign operations. As a result, a portion of unrealized foreign exchange gains and losses on the U.S. dollar denominated long-term debt are included in the cumulative translation account in other comprehensive income. On an ongoing basis, an assessment is made as to whether the designated derivative financial instruments continue to be effective in offsetting changes in cash flows of the hedged transactions.
Income Taxes	(t) Income Taxes Income tax expense represents the sum of current income tax and deferred tax. Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. Taxable earnings differ from earnings as reported in the consolidated statements of earnings as it excludes temporary and permanent differences. The Company’s current tax assets and liabilities are calculated by using tax rates that have been enacted or substantively enacted at the reporting date. Deferred income tax is recognized on all temporary differences at the reporting date based on the difference between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable profit, with the following exceptions: • Where the temporary difference arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss; • In respect of taxable temporary differences associated with investments in subsidiaries, associates and joint ventures, where the timing of the reversal of the temporary difference can be controlled and it is probable that the temporary difference will not reverse in the foreseeable future; and • Deferred income tax assets are recognized only to the extent that it is probable that a taxable profit will be available against which the deductible temporary differences, carried forward tax credits or tax losses can be utilized. The carrying amount of deferred income tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax assets to be utilized. Unrecognized deferred income tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered. Deferred income tax assets and liabilities are measured on an undiscounted basis at the tax rates that are expected to apply when the asset is realized or the liability is settled, based on tax rates and tax laws enacted or substantively enacted at the reporting date. Current and deferred income taxes are charged or credited directly to equity if it relates to items that are credited or charged to equity in the same period. Otherwise, income tax is recognized in the consolidated statements of earnings. In accordance with IAS 12 Income taxes non-monetary
Earnings Per Share	(u) Earnings Per Share Basic earnings per share is calculated by dividing the net earnings for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by adjusting the weighted average number of common shares outstanding for dilutive common shares related to the Company’s equity share-based compensation plan.
Finance Income and Costs	(v) Finance Income and Costs Finance income comprises interest income on funds invested. Finance income is recognized as it accrues in profit or loss, using the effective interest rate method. Finance costs comprise interest expense on borrowings and interest incurred on lease liabilities.
Government Grants	(w) Government Grants Government grants are recorded as a reduction in cost of goods sold and selling and administrative expense within the consolidated statements of earnings in accordance with where the associated expense was recognized. Government grants are recognized when there is reasonable assurance that the grant will be received, and all related conditions are complied with.
