Material Accounting Policies | 3. MATERIAL ACCOUNTING POLICIES Foreign exchange transactions Transactions in currencies other than the Company’s functional currency are recognized at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary items denominated in foreign currencies are translated at the rates prevailing at that date. Non-monetary re-translated. Financial Instruments The Company’s financial assets and liabilities (financial instruments) include cash, restricted cash, accounts receivable, bank indebtedness, accounts payable and accrued liabilities, financing arrangement, warrant liability, earnout liability, share-based payment compensation liability and governmental loans. Recognition Financial assets and financial liabilities are recognised in the consolidated statements of financial position when the Company becomes party to the contractual provisions of the instrument, and they are initially measured at fair value. Financial assets are derecognized when the contractual rights to the cash flows expire or when the Company transfers substantially all the risks and rewards of ownership of the financial assets to another party. Financial liabilities are derecognized when the contractual obligations are discharged, cancelled, or expired. A write-off Write-off Classification and measurement The classification of financial instruments is determined at the time of initial recognition, within the following categories: ● Amortized cost ● Fair value through profit (loss) (FVTP(L)) ● Fair value through other comprehensive income (loss) (FVTOCI(L)) Financial assets are classified and subsequently measured based on the business model in which they are managed and ● The financial asset is held within a business model with the objective of holding the financial asset in order to collect contractual cash flows; and ● The contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. All other financial assets are measured at their fair values at each subsequent reporting period, with any changes recorded through profit and loss or through other comprehensive income (loss), if the designation is made as an irrevocable election upon initial recognition. Financial liabilities are classified as subsequently measured at amortized cost or FVTP(L). A financial liability is classified as FVTP(L) if it is contingent consideration of an acquirer in a business combination, held-for-trading, Impairment of financial assets carried at amortized cost The Company utilizes an ‘expected credit loss’ (“ECL”) model, as required by IFRS 9 – Financial Instruments The Company reviews its accounts receivable at each reporting date and considers both current and forward-looking macro-economic factors that may affect historical default rates when estimating ECL. Accounts receivable, together with the associated allowance, are written off when there is no realistic prospect of future recovery and all collateral has been realized or has been transferred to the Company. If, in a subsequent year, the amount of the estimated impairment loss increases or decreases because of an event occurring after the impairment was recognized, the previously recognized impairment loss is increased or decreased by adjusting the carrying value of the loan or receivable. If a past write-off Fair value of financial instruments Fair value is the price that would be received when selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In assessing the fair value of a particular contract, the market participant would consider the credit risk of the counterparty to the contract. Consequently, when it is appropriate to do so, the Company adjusts the valuation models to incorporate a measure of credit risk. Fair value represents management’s estimates of the current market value at a given point in time. The Company has certain financial assets and liabilities that are measured at fair value. The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability (for example, interest rate The Company reclassifies financial assets only when its business model for managing those assets changes. Financial liabilities are not reclassified. Accounts receivable Accounts receivable are recognized initially at transaction price and are non-interest Inventories Raw materials, work in process and finished products inventories are measured at the lower of average cost and net realizable value. Average cost for finished goods and work in process is comprised of direct costs and an allocation of production overheads, including depreciation expense. Supplies inventories are measured at the lower of average cost and net realizable value. Property, plant and equipment, net Items of property, plant and equipment are recorded at cost less accumulated depreciation and impairment. The cost of an item of property or equipment comprises costs that can be directly attributed to its acquisition and to bringing the asset to a working condition for its intended use, including borrowing costs that meet the criteria for capitalization and initial estimates of the cost of dismantling and removing the item and restoring the site on which it is located. The cost of self-constructed and self-installed assets includes the cost of direct labour in addition to the costs listed above. Depreciation is calculated by the straight-line method based on estimated useful lives as follows: Category of Property, Plant and Equipment Range of Estimated Useful Life Buildings 5 to 30 years Machinery and equipment 5 to 40 years Vehicles 6 to 12 years Computer hardware 3 to 5 years The Company also separately recognizes the cost of replacement parts and major overhaul or inspection costs if the cost of the item can be reliably measured or estimated and it is probable that the future economic benefits will be realized by the Company. When such items are replaced the carrying amount of the replaced component is derecognized. The costs of maintenance and repairs of property, plant and equipment are recognized in profit or loss as incurred. Componentization When significant components of an item of property, plant and equipment have different useful lives, they are accounted for as separate items and depreciated over the respective useful lives. Useful life, depreciation method, residual value Estimates of the useful lives of items of property, plant and equipment are based on management’s judgement as to the physical and economic useful lives of assets and as such are subject to change in future periods. Depreciation methods, useful lives and residual values are reviewed at each reporting date with the effect of any changes in estimate being accounted for on a prospective basis. Derecognition of property plant and equipment An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on the disposal or retirement of an item of property, plant and equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in profit or loss. Impairment of tangible and intangible assets Property, plant and equipment and intangible assets are reviewed at the end of each reporting period to determine whether there is any indication of impairment. If any such indication exists then the recoverable amount of the asset is estimated. The recoverable amount of an asset is defined as the higher of its fair value less costs to sell and its value in use. Where it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the Cash Generated Unit (“CGU”) to which the asset belongs. The CGU corresponds to the smallest identifiable group of assets whose continuing use generates cash inflows that are largely independent of the cash flows from other groups of assets. An impairment loss is recognized when the carrying amount of an asset, or of the CGU to which it belongs, exceeds the recoverable amount. In determining value in use, the Company estimates cash flows before taxes based on most recent actual results and forecasts and then determines the current value of future estimated cash flows. During the year ended March 31, 2024, there were no indicators of impairment in regards to the Company’s CGU however during the year ended March 31, 2023, there were indicators of impairment. The carrying value of the net assets of the Company exceeded its market capitalization on March 31, 2023 and impacts of the economic conditions pertaining to the steel manufacturing industry were two indicators identified. Management, in consultation with external specialists, conducted an impairment test and concluded that there was no impairment. The impairment test showed that the recoverable amount exceeded the carrying value of the net assets of the Company. Impairment losses are recognized in the consolidated statements of net income. An impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. The increased carrying amount of an asset attributable to a reversal of impairment loss may not exceed the carrying amount that would have been determined had no impairment loss been recognized in prior periods. Leases At inception of a contract, the Company assesses whether the contract is, or contains, a lease The Company, as a lessee, recognizes a right-of-use The Company has elected not to recognize right-of-use low-value Retirement benefit costs The Company provides pensions and certain health care, dental care, life insurance and other benefits for certain retired employees pursuant to Company policy. For defined benefit pension plans and other post-employment benefits, the defined benefit cost is actuarially determined on an annual basis by independent actuaries using the projected unit credit method. Remeasurement comprising of actuarial gains and losses, the effect of the asset ceiling and the return on plan assets (excluding interest) are recognized immediately in the consolidated statements of financial position with a charge to other comprehensive income in the period in which they occur. The Company has elected to transfer those amounts recognized in other comprehensive income (loss) to a separate reserve within equity. Net-interest ● service cost, past-service cost, gains and losses on curtailments and settlements; ● net interest expense; and ● remeasurement. The Company recognizes the first two components of defined benefit costs in profit or loss in its consolidated statements of net income: service cost, past service cost, gains and losses on curtailments and settlements in Cost of sales and Administrative and selling expenses; and net interest expense in Interest on pension and other post-employment benefit obligations. The determination of a benefit expense requires assumptions such as the discount rate, the expected mortality, the expected rate of future compensation increases and the expected healthcare cost trend rate. Actual results will differ from estimated results which are based on these assumptions. The asset or liability recognized in the consolidated statements of financial position represents the actual plan situation in the Company’s defined benefit and other post-employment benefit plans. All actuarial gains and losses that arise in calculating the present value of the defined benefit obligation and the plan assets, the remeasurement components, are recognized immediately in other comprehensive income (loss). Any defined benefit asset resulting from this calculation is limited to the present value of any economic benefit in the form of refunds from the plan or reduction in future contributions to the plan. Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the contributions. Termination benefits Termination benefits are recognized as an expense when the Company is demonstrably committed, without realistic possibility of withdrawal, to a formal detailed plan to either terminate employment before the normal retirement date, or to provide termination benefits as a result of an offer made to encourage voluntary retirement. Termination benefits for voluntary retirements are recognized the earlier of the date when the Company recognizes related restructuring costs and the date when the Company can no longer withdraw the offer of the benefits related to the voluntary retirement. Short-term benefits Short-term employee benefit obligations are measured on an undiscounted basis and are expensed as the related service is provided. A liability is recognized for the amount expected to be paid under short-term cash bonus or profit-sharing plans if the Company has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably. Environmental liabilities An environmental liability is recognized if, as a result of an agreement, the Company has a present legal obligation that can be estimated reliably and it is probable that an outflow of economic benefits will be required to settle the obligation. The amount recognized as an environmental liability is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account risks and uncertainty of cash flows. Where the effect of discounting is material, environmental liabilities are determined by discounting the expected future cash flows at a pre-tax Revenue recognition The Company’s revenue is generated primarily from contracts to produce, ship and deliver steel products, and to a lesser extent, to deliver non-steel by-products Revenue is measured at the fair value of the consideration received or receivable, net of returns and allowances, trade discounts, volume rebates and other incentives. Revenue from the sale of goods is recognized to the extent that it is probable that the economic benefits will flow to the Company, can be reliably measured, and at a point-in-time Freight and other transportation costs billed to customers are recorded gross within revenue and cost of goods sold. Non-steel by-products by-products by-products by-products by-products. The Company has pricing latitude in revenue arrangements and is also exposed to inventory and credit risks. The Company offers industry standard payment terms that typically requires payment from customers 30 days after title and control transfers. Government funding The benefit of Government funding is not recognized until there is reasonable assurance that the Company will comply with the conditions attaching to it and that the funding will be received. Benefits related to Government funding in the form of low interest rate loans, interest free loans and grants for items of capital are presented in the consolidated statements of financial position as an offset to the carrying value of the property, plant and equipment to which the benefits relate. In the case of low interest rate loans and interest free loans, the benefit is calculated as the difference between the fair value amount of the low interest rate loan or the interest free loan and the proceeds received. Claims under government grant programs related to income are recorded within the consolidated statements of net income as a reduction of the related item the grant is intended to offset, in the period in which the eligible expenses were incurred or when the services have been performed. Research Research costs are expensed as incurred, due to the nature of the projects. Where government incentives in the form of investment tax credits and grants are received for research projects initiated by the Company for its own purposes, these incentives are deducted from the applicable category of expenditures. Finance cost Finance cost is comprised of interest expense on borrowings, amortization of issuance costs, and accretion of environmental liabilities. Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are recognized in profit or loss using the effective interest method. Actuarially determined interest costs related to the defined benefit pension obligation and the other post-employment benefit obligation are recorded respectively as components of the carrying amount of the accrued pension liability and the accrued other post-employment benefit obligation. Taxation Current and deferred income tax are recognized in net income, except when they relate to items that are recognized in other comprehensive income (loss) or directly in equity, in which case, the current and deferred income tax are also recognized in other comprehensive income (loss) or directly in equity, respectively. Current tax The current tax expense is based on taxable income for the year. Taxable income differs from net income before taxes as reported in the consolidated statements of net income because of items of income or expense that are taxable or deductible in other years and items that are never taxable or deductible. The Company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the end of the reporting period. Deferred income tax Deferred income tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable income. Deferred income tax liabilities are generally recognized for all taxable temporary differences. Deferred income tax assets are generally recognized for all deductible temporary differences to the extent that it is probable that taxable income will be available against which those deductible temporary differences can be utilised. The carrying amount of deferred income tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no longer probable that sufficient taxable income will be available to allow all or part of the asset to be recovered. Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the asset is realised or the liability is settled, based on tax rates and tax laws that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred income tax assets and liabilities reflects the tax consequences, based on management’s expectation at the end of the reporting period, that would follow from the recovery or settlement of the carrying amount of its assets and liabilities. Share-based payment The Company provides certain employees with long-term incentive awards. Equity-settled share-based payments to employees and others providing similar services are measured at the fair value of the equity instruments at the grant date. The fair value includes the effect of market based vesting conditions but excludes the effect of performance conditions. Details regarding the determination of the fair value of equity-settled share-based transactions are set out in Note 34. The fair value determined at the grant date of the equity-settled share-based payments is expensed on a straight-line basis over the expected vesting period, which is determined based on the Company’s expected timing on meeting the performance condition. The impact of the revision of the original estimates, if any, is recognized in profit or loss such that the cumulative expense reflects the revised estimate, with a corresponding adjustment to equity. For cash-settled share-based payments, a liability is recognized for the goods or services acquired, measured initially at the fair value of the liability. At each reporting date until the liability is settled, and at the date of settlement, the fair value of the liability is remeasured, with any changes in fair value recognized in profit or loss for the year. Comprehensive Income (Loss) Other comprehensive income (loss) (“OCI”) includes foreign exchange gain on translation to the Company’s presentation currency from the US Dollar functional currency. OCI includes actuarially determined gains and losses on post employment benefits offered to certain employees and the effect of any limits applied to the defined benefit asset. OCI also includes unrealized loss on cash flow hedge reserve. Comprehensive income is composed of net income and OCI. Accumulated OCI is a separate component of Shareholders’ Equity which includes the accumulated balances of all components of OCI which are recognized in comprehensive income but excluded from net income. New IFRS Standards, Amendments and Interpretations adopted as of April 1, 2023 (effective January 1, 2023) The Company adopted the following amendments which did not have a material impact on the consolidated financial statements: Amended Disclosure for Accounting Policies IAS 1 “Presentation of Financial Statements” was amended with the intention to help companies provide useful accounting policy disclosures. The key amendments include the requirement to disclose material accounting policy information rather than significant accounting policies, clarifying that accounting policies related to immaterial transactions, other events or conditions are themselves immaterial and as such need not be disclosed; and clarifying that not all accounting policies that relate to material transactions, other events or conditions are themselves material to a company’s financial statements. Amended Scope of Recognition IAS 12 “Income Taxes” was amended to narrow the scope of recognition exemption in paragraphs 15 and 24 (recognition exemption) so that it no longer applies to transactions that, on initial recognition, give rise to Definition of Accounting Estimates IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors” was Standards and Interpretations issued and not yet adopted Classification of Liabilities as Current or Non-current In January 2020, the IASB issued an amendment to IAS 1 Presentation of Financial Statements non-current Non-Current non-current |

Critical Estimates and Judgements | 4. CRITICAL ESTIMATES AND JUDGEMENTS The preparation of these consolidated financial statements, in accordance with IFRS, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Judgement is used mainly in determining whether a balance or transaction should be recognized in the consolidated financial statements. Estimates and assumptions are used mainly in determining the measurement of recognized transactions and balances. However, judgement and estimates are often interrelated. In the determination of CGU, the Company assessed its identifiable group of assets that generates cash inflows and concluded the Company has a single cash generating unit. Judgements, estimates and assumptions 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. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in future periods affected. The following discussion sets forth management’s most critical estimates and assumptions in determining the value of assets, liabilities, revenue and expenses: Allowance for doubtful accounts Management analyzes accounts receivable to determine the allowance for doubtful accounts by assessing the collectability of receivables owing from each individual customer. This assessment takes into consideration certain factors including the age of outstanding receivable, customer-operating performance, historical payment patterns and current collection efforts, relevant forward-looking information and the Company’s security interests, if any. Useful lives of property, plant and equipment and Intangible assets The Company reviews the estimated useful lives of property, plant and equipment and intangible assets at the end of each annual reporting period, and whenever events or circumstances indicate a change in useful life. Estimated useful lives of items of property, plant and equipment and intangible assets are based on a best estimate and the actual useful lives may be different. Impairment of property, plant and equipment and Intangible assets Determining whether property, plant and equipment and intangible assets are impaired requires the Company to determine the recoverable amount of the CGU to which the asset is allocated. To determine the recoverable amount of the CGU, management is required to estimate its fair value. To calculate the value of the CGU in use, management determines expected future cash flows, which involves, among other items, forecasted steel selling prices, forecasted tons shipped, costs and volume of production, growth rate, and the estimated selling costs, using an appropriate discount rate. Defined Benefit Retirement Plans The Company’s determination of employee benefit expense and obligations requires the use of assumptions such as the discount rate applied to determine the present value of all future cash flows expected in the plan. Since the determination of the cost and obligations associated with employee future benefits requires the use of various assumptions, there is measurement uncertainty inherent in the actuarial valuation process. Actual results could differ from estimated results which are based on assumptions. Taxation The Company computes and recognizes an income tax provision in each of the jurisdictions in which it operates. Actual amounts of income tax expense and scientific research and experimental development investment tax credits only become final upon filing and acceptance of the returns by the relevant authorities, which occur subsequent to the issuance of the consolidated financial statements. Additionally, the estimation of income taxes includes evaluating the recoverability of deferred income tax assets based on an assessment of the ability to use the underlying future tax deductions before they expire against future taxable income. The assessment is based upon existing tax laws and estimates of future taxable income. To the extent estimates differ from the final tax return, net income will be affected in a subsequent period. The Company will file tax returns that may contain interpretations of tax law and estimates. Positions taken and estimates utilized by the Company may be challenged by the relevant tax authorities. Rulings that result in adjustments to tax returns filed will be recorded in the period where the ruling is made known to the Company. |

As a result of the Company changing to electric arc furnaces (“EAF”) to replace the existing blast furnace and basic oxygen steelmaking operations, the Company has been reviewing the useful lives for those assets expected to be decommissioned once the EAF is operational. Effective October 1, 2023, there was sufficient evidence to support a change in the useful lives of machinery, equipment and buildings involved in blast furnace steelmaking operations. The remaining useful lives of this machinery, equipment and buildings have been adjusted to be fully depreciated by December 31, 2029. As a result of this change in estimate, depreciation for the year ended March 31, 2024 has increased by $12.5 million. It is expected that there will be a quarterly impact of approximately $6.1 million to $6.4 million until December 31, 2029.

PENSION BENEFITS Defined contribution plan The Company maintains a defined contribution pension plan established by Old Steelco Inc.’s predecessor in 2004 for non-unionized 5 2 non-unionized The pension expense under this plan is equal to the Company’s contribution. The pension expense for the year ended March 31, 2024 was $13.1 million (March 31, 2023 was $10.2 million). Defined benefit plans The Company maintains non-contributory The Company also maintains a closed plan for pensioners who retired prior to January 1, 2002, that provides the pensioners with a pension benefit in excess of the limits provided by the Ontario Pension Benefit Guarantee Fund (the “Closed Retiree Plan”).

Contributions for the year ended March 31, 2024 under these regulations were $17.5 million (March 31, 2023 - $16.5 million). The Company’s expected future contributions in respect of its defined benefit pension plans for the fiscal year ending March 31, 2025 is $26.9 million. Sensitivity of results to actuarial assumptions The sensitivity of the defined benefit obligation to the key actuarial assumptions is as follows: Year ended, March 31, March 31, Effect of change in discount rate assumption One percentage point increase $ (123.1) $ (118.5) One percentage point decrease $ 147.4 $ 141.8 Effect of change in salary scale One percentage point increase $ 17.4 $ 18.8 One percentage point decrease $ (15.9) $ (17.0) Effect of change in mortality assumption Set forward one year $ 33.1 $ 31.5 Set back one year $ (34.0) $ (32.4) The discount rate sensitivities presented above are estimates based on plan durations. The defined benefit obligation and the current service cost have an implied duration of 10 and 17 years, respectively at current discount rates. If the returns on plan assets had been 10% lower than the actual returns of plan assets experienced in the year ended March 31, 2024, the actuarial loss immediately recognized in other comprehensive income would have increased by approximately $105.0 million (March 31, 2023 - $130.0 million). |

These agreements provide the Company with comfort that an adequate supply of these key raw materials will be available to the Company at a price acceptable to the Company. Legal Matters Additionally, from time to time, in the ordinary course of business, the Company is a defendant or party to a number of pending or threatened legal actions and proceedings. Although such matters cannot be predicted with certainty, management currently considers the Company’s exposure to such ordinary course claims and litigation, to the extent not covered by the Company’s insurance policies or otherwise provided for, not to have a material adverse effect on these consolidated financial statements. In addition, the Company is involved in and potentially subject to regular audits from federal and provincial tax authorities relating to income, capital and commodity taxes and, as a result of these audits, may receive assessments and reassessments. |

T Substantial Issuer Bid On June 21, 2022, the Company commenced a substantial issuer bid in Canada and a Tender Offer in the United States (collectively the “Offer”) to purchase for cancellation up to US $400 million of its common shares. The Offer which expired on July 27, 2022, proceeded by way of a “modified Dutch auction”, whereby, shareholders who chose to participate in the Offer could individually select the price, within a price range of not less than US $8.75 and not more than US $10.25 per share (in increments of US $0.10 per share), at which they tender their shares to the Offer. Upon expiry of the Offer, the Company determined the lowest purchase price that allowed it to purchase the maximum number of shares properly tendered to the Offer, and not properly withdrawn, having an aggregate purchase price not exceeding US $400 million. On July 27, 2022, 41,025,641 common shares at a weighted average book value of $9.11 (US $7.33) per share were purchased for cancellation at US $9.75 per share, for an aggregate amount of $514.9 million (US $400 million). As a result, the Company subsequently adjusted the number of common shares and the reduction to retained earnings to actual. The excess of the purchase price over the carrying value of the shares purchased totalling $127.4 million (US $99.3 million) was recognized as a reduction to retained earnings. The Company incurred transaction costs of $1.1 million related to the SIB which were recorded within capital stock. |

NET INCOME PER COMMON SHARE The following table sets forth the computation of basic and diluted net income per common share: Year ended, March 31, March 31, (in millions) Net income attributable to ordinary shareholders $ 105.2 $ 298.5 Gain on change in fair value of warrants (i) (12.1 ) (47.7 ) Net income attributable to ordinary shareholders (diluted) $ 93.1 $ 250.8 (in millions) Weighted average common shares outstanding (ii) 108.4 122.7 Dilutive effect of warrants, restricted share units and performance share units (i) (ii) 24.6 24.3 Dilutive weighted average common shares outstanding 133.0 147.0 Net income per common share: Basic $ 0.97 $ 2.43 Diluted $ 0.70 $ 1.71 (i) As at March 31, 2024, 24,179,000 warrants remain outstanding. For the purposes of determining diluted net income per common share, net income for the year ended March 31, 2024 was adjusted for the change in the fair value of the warrants in the amount of $12.1 million (US $9.2 million) as the warrants were determined to be dilutive (March 31, 2023 - $47.7 million; US $37.2 million). (ii) On May 17, 2022, the Board of Directors granted 141,203 and 556,348 restricted share units and performance share units, respectively, to various employees of the Company under the Omnibus Plan for the fiscal year ended March 31, 2023 (“FY2023 Plan”).

For the purposes of determining diluted net income per share, the restricted share units and performance share units are considered contingently issuable potential ordinary shares. The treasury stock method is applied based on the number of units that vest based on achievement of various financial and nonfinancial targets. Based on the achievement of such targets and forfeiture of awards, the restricted share units and performance share units included in diluted net income per share for the year ended March 31, 2024 is 376,268 common shares (March 31, 2023 – 92,293 common shares). See Note 34. For the year ended March 31, 2024, the total weighted average common shares issued and outstanding is 103,793,360 (March 31, 2023 – 117,945,286). The Company issued earnout rights and Replacement LTIP awards in connection with the Company’s merger transaction from fiscal 2022. For the year ended March 31, 2024, 1,404,357 (March 31, 2023 – 1,557,026) weighted average earnout rights have been included in the calculation of basic and diluted net income per common share. Replacement LTIP awards are included within the weighted average Replacement LTIP awards have been included in the calculation of basic and diluted net income per common share. See Note 31 and Note 32. The Company also routinely grants DSUs to Directors of the Company under its Omnibus Equity Incentive Plan (“Omnibus Plan”). DSUs as vested to various Directors of the Company in respect of their annual retainers. The DSUs recognized under the Omnibus Plan are included within the weighted average common shares outstanding, as the units are exercisable for no consideration. For the year ended March 31, 2024, 272,166 (March 31, 2023 – 108,628) weighted average DSUs have been included in the calculation of basic and diluted net income per common share. See Note 34. |

The fair value of the Revolving Credit Facility, disclosed in Note 15 approximates the respective carrying value due to variable interest rates. The fair value of the financing arrangement included in other long-term liabilities approximates The fair value of the various government funding are classified as Level 2 and are estimated based on a discounted cash flow model applying current rates offered to the Company for financial instruments subject to similar risk and maturities. The carrying value of government funding generally approximate its fair value. The fair value of steel commodity swaps are classified as Level 2 and is calculated using the mark-to-market The fair values of the warrant liability, earnout liability and the share-based payment compensation liability are classified as Level 1 and are calculated using the quoted market price of the Company’s common shares at the end of each reporting period.

The Company may use derivative financial instruments to hedge certain Credit risk Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises primarily from the Company’s receivables from customers. The Company has an established credit policy under which each new customer is analyzed individually for creditworthiness before the Company’s standard payment and delivery terms and conditions are offered. The Company’s review includes a review of the potential customer’s financial information, external credit ratings and bank and supplier references. Credit limits are established for each new customer and customers that fail to meet the Company’s credit requirements may transact with the Company only on a prepayment basis. The maximum credit exposure at March 31, 2024 is the carrying amount of accounts receivable of $ million (March 31, 2023 - $ million). At March 31, 2024, there was one customer account greater than % of the carrying amount of accounts receivable. At March 31, 2023, there was no customer account greater than % of the carrying amount of accounts receivable. As at March 31, 2024, $ million, or % (March 31, 2023 - $ million, or %), of accounts receivable were more than days old. The Company establishes an allowance for doubtful accounts that represents its estimate of losses in respect of accounts receivable. The main components of this allowance are a specific provision that relates to individual exposures and a provision for expected losses that have been incurred but not yet identified. The allowance for doubtful accounts at March 31, 2024 was $3.1 million (March 31, 2023 - $0.5 million), as disclosed in Note 12. The Company may be exposed to certain losses in the event of non-performance Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they come due. The Company manages liquidity risk by maintaining adequate cash balances. The Company continuously monitors and reviews actual and forecasted cash flows to ensure adequate liquidity and anticipate liquidity requirements.

The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing the return on risk. As disclosed in Note 19, during the years ended March 31, 2024 and March 31, 2023, the Company was not a party to agreements to hedge the commodity price risk associated with the revenue on the sale of steel. When the Company is party to hedging agreements, these activities are carried out under the oversight of the Company’s Board of Directors. Currency risk The Company is exposed to currency risk on purchases, labour costs and pension and other post retirement employment benefits liabilities that are denominated in Canadian dollars. The prices for steel products sold in Canada are derived mainly from price levels in the US market in US dollars converted into Canadian dollars at the prevailing exchange rates. As a result, a stronger US dollar relative to the Canadian dollar increases the Company’s Canadian dollar selling prices for sales within Canada. The Company’s Canadian dollar denominated financial instruments as at March 31, 2024 and March 31, 2023, were as follows: As at, March 31, March 31, Cash $ 1.5 $ 51.2 Restricted cash 3.9 3.9 Accounts receivable 78.0 127.1 Accounts payable and accrued liabilities (145.5 ) (147.1 ) Governmental loans (143.6 ) (120.4 ) Other long-term liabilities (17.0 ) (3.3 ) Net Canadian dollar denominated financial instruments $ (222.7 ) $ (88.6 ) A $0.01 decrease (or increase) in the US dollar relative to the Canadian dollar for the year ended March 31, 2024 would not Interest rate risk Interest rate risk is the risk that the value of the Company’s assets and liabilities will be affected by a change in interest rates. The Company’s interest rate risk mainly arises from the interest rate impact on its banking facilities and debt. The Company may manage interest rate risk through the periodic use of interest rate swaps. For the years ended March 31, 2024 and March 31, 2023, a one percent Commodity price risk The Company is subject to price risk from fluctuations in the market prices of commodities, including natural gas, iron ore and coal. The Company enters into supply agreements for certain of these commodities as disclosed in Note 25. To manage risks associated with future variability in cash flows attributable to certain commodity purchases, the Company may use derivative instruments with maturities of 12 months or less as disclosed in Note 19 to hedge the commodity price risk associated with the revenue on the sale of steel. At March 31, 2024 and March 31, 2023, the Company had no commodity-based swap contracts. |

Financial Instruments | Financial Instruments The Company’s financial assets and liabilities (financial instruments) include cash, restricted cash, accounts receivable, bank indebtedness, accounts payable and accrued liabilities, financing arrangement, warrant liability, earnout liability, share-based payment compensation liability and governmental loans. Recognition Financial assets and financial liabilities are recognised in the consolidated statements of financial position when the Company becomes party to the contractual provisions of the instrument, and they are initially measured at fair value. Financial assets are derecognized when the contractual rights to the cash flows expire or when the Company transfers substantially all the risks and rewards of ownership of the financial assets to another party. Financial liabilities are derecognized when the contractual obligations are discharged, cancelled, or expired. A write-off Write-off Classification and measurement The classification of financial instruments is determined at the time of initial recognition, within the following categories: ● Amortized cost ● Fair value through profit (loss) (FVTP(L)) ● Fair value through other comprehensive income (loss) (FVTOCI(L)) Financial assets are classified and subsequently measured based on the business model in which they are managed and ● The financial asset is held within a business model with the objective of holding the financial asset in order to collect contractual cash flows; and ● The contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. All other financial assets are measured at their fair values at each subsequent reporting period, with any changes recorded through profit and loss or through other comprehensive income (loss), if the designation is made as an irrevocable election upon initial recognition. Financial liabilities are classified as subsequently measured at amortized cost or FVTP(L). A financial liability is classified as FVTP(L) if it is contingent consideration of an acquirer in a business combination, held-for-trading, Impairment of financial assets carried at amortized cost The Company utilizes an ‘expected credit loss’ (“ECL”) model, as required by IFRS 9 – Financial Instruments The Company reviews its accounts receivable at each reporting date and considers both current and forward-looking macro-economic factors that may affect historical default rates when estimating ECL. Accounts receivable, together with the associated allowance, are written off when there is no realistic prospect of future recovery and all collateral has been realized or has been transferred to the Company. If, in a subsequent year, the amount of the estimated impairment loss increases or decreases because of an event occurring after the impairment was recognized, the previously recognized impairment loss is increased or decreased by adjusting the carrying value of the loan or receivable. If a past write-off |
Fair value of financial instruments | Fair value of financial instruments Fair value is the price that would be received when selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In assessing the fair value of a particular contract, the market participant would consider the credit risk of the counterparty to the contract. Consequently, when it is appropriate to do so, the Company adjusts the valuation models to incorporate a measure of credit risk. Fair value represents management’s estimates of the current market value at a given point in time. The Company has certain financial assets and liabilities that are measured at fair value. The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability (for example, interest rate The Company reclassifies financial assets only when its business model for managing those assets changes. Financial liabilities are not reclassified. |

Inventories | Inventories Raw materials, work in process and finished products inventories are measured at the lower of average cost and net realizable value. Average cost for finished goods and work in process is comprised of direct costs and an allocation of production overheads, including depreciation expense. Supplies inventories are measured at the lower of average cost and net realizable value. |
Property, plant and equipment, net | Property, plant and equipment, net Items of property, plant and equipment are recorded at cost less accumulated depreciation and impairment. The cost of an item of property or equipment comprises costs that can be directly attributed to its acquisition and to bringing the asset to a working condition for its intended use, including borrowing costs that meet the criteria for capitalization and initial estimates of the cost of dismantling and removing the item and restoring the site on which it is located. The cost of self-constructed and self-installed assets includes the cost of direct labour in addition to the costs listed above. Depreciation is calculated by the straight-line method based on estimated useful lives as follows: Category of Property, Plant and Equipment Range of Estimated Useful Life Buildings 5 to 30 years Machinery and equipment 5 to 40 years Vehicles 6 to 12 years Computer hardware 3 to 5 years The Company also separately recognizes the cost of replacement parts and major overhaul or inspection costs if the cost of the item can be reliably measured or estimated and it is probable that the future economic benefits will be realized by the Company. When such items are replaced the carrying amount of the replaced component is derecognized. The costs of maintenance and repairs of property, plant and equipment are recognized in profit or loss as incurred. Componentization When significant components of an item of property, plant and equipment have different useful lives, they are accounted for as separate items and depreciated over the respective useful lives. Useful life, depreciation method, residual value Estimates of the useful lives of items of property, plant and equipment are based on management’s judgement as to the physical and economic useful lives of assets and as such are subject to change in future periods. Depreciation methods, useful lives and residual values are reviewed at each reporting date with the effect of any changes in estimate being accounted for on a prospective basis. Derecognition of property plant and equipment An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on the disposal or retirement of an item of property, plant and equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in profit or loss. |
Impairment of tangible and intangible assets | Impairment of tangible and intangible assets Property, plant and equipment and intangible assets are reviewed at the end of each reporting period to determine whether there is any indication of impairment. If any such indication exists then the recoverable amount of the asset is estimated. The recoverable amount of an asset is defined as the higher of its fair value less costs to sell and its value in use. Where it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the Cash Generated Unit (“CGU”) to which the asset belongs. The CGU corresponds to the smallest identifiable group of assets whose continuing use generates cash inflows that are largely independent of the cash flows from other groups of assets. An impairment loss is recognized when the carrying amount of an asset, or of the CGU to which it belongs, exceeds the recoverable amount. In determining value in use, the Company estimates cash flows before taxes based on most recent actual results and forecasts and then determines the current value of future estimated cash flows. During the year ended March 31, 2024, there were no indicators of impairment in regards to the Company’s CGU however during the year ended March 31, 2023, there were indicators of impairment. The carrying value of the net assets of the Company exceeded its market capitalization on March 31, 2023 and impacts of the economic conditions pertaining to the steel manufacturing industry were two indicators identified. Management, in consultation with external specialists, conducted an impairment test and concluded that there was no impairment. The impairment test showed that the recoverable amount exceeded the carrying value of the net assets of the Company. Impairment losses are recognized in the consolidated statements of net income. An impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. The increased carrying amount of an asset attributable to a reversal of impairment loss may not exceed the carrying amount that would have been determined had no impairment loss been recognized in prior periods. |
Leases | Leases At inception of a contract, the Company assesses whether the contract is, or contains, a lease The Company, as a lessee, recognizes a right-of-use The Company has elected not to recognize right-of-use low-value |
Retirement benefit costs | Retirement benefit costs The Company provides pensions and certain health care, dental care, life insurance and other benefits for certain retired employees pursuant to Company policy. For defined benefit pension plans and other post-employment benefits, the defined benefit cost is actuarially determined on an annual basis by independent actuaries using the projected unit credit method. Remeasurement comprising of actuarial gains and losses, the effect of the asset ceiling and the return on plan assets (excluding interest) are recognized immediately in the consolidated statements of financial position with a charge to other comprehensive income in the period in which they occur. The Company has elected to transfer those amounts recognized in other comprehensive income (loss) to a separate reserve within equity. Net-interest ● service cost, past-service cost, gains and losses on curtailments and settlements; ● net interest expense; and ● remeasurement. The Company recognizes the first two components of defined benefit costs in profit or loss in its consolidated statements of net income: service cost, past service cost, gains and losses on curtailments and settlements in Cost of sales and Administrative and selling expenses; and net interest expense in Interest on pension and other post-employment benefit obligations. The determination of a benefit expense requires assumptions such as the discount rate, the expected mortality, the expected rate of future compensation increases and the expected healthcare cost trend rate. Actual results will differ from estimated results which are based on these assumptions. The asset or liability recognized in the consolidated statements of financial position represents the actual plan situation in the Company’s defined benefit and other post-employment benefit plans. All actuarial gains and losses that arise in calculating the present value of the defined benefit obligation and the plan assets, the remeasurement components, are recognized immediately in other comprehensive income (loss). Any defined benefit asset resulting from this calculation is limited to the present value of any economic benefit in the form of refunds from the plan or reduction in future contributions to the plan. Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the contributions. |
Termination benefits | Termination benefits Termination benefits are recognized as an expense when the Company is demonstrably committed, without realistic possibility of withdrawal, to a formal detailed plan to either terminate employment before the normal retirement date, or to provide termination benefits as a result of an offer made to encourage voluntary retirement. Termination benefits for voluntary retirements are recognized the earlier of the date when the Company recognizes related restructuring costs and the date when the Company can no longer withdraw the offer of the benefits related to the voluntary retirement. |
Short-term benefits | Short-term benefits Short-term employee benefit obligations are measured on an undiscounted basis and are expensed as the related service is provided. A liability is recognized for the amount expected to be paid under short-term cash bonus or profit-sharing plans if the Company has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably. |
Environmental liabilities | Environmental liabilities An environmental liability is recognized if, as a result of an agreement, the Company has a present legal obligation that can be estimated reliably and it is probable that an outflow of economic benefits will be required to settle the obligation. The amount recognized as an environmental liability is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account risks and uncertainty of cash flows. Where the effect of discounting is material, environmental liabilities are determined by discounting the expected future cash flows at a pre-tax |
Revenue recognition | Revenue recognition The Company’s revenue is generated primarily from contracts to produce, ship and deliver steel products, and to a lesser extent, to deliver non-steel by-products Revenue is measured at the fair value of the consideration received or receivable, net of returns and allowances, trade discounts, volume rebates and other incentives. Revenue from the sale of goods is recognized to the extent that it is probable that the economic benefits will flow to the Company, can be reliably measured, and at a point-in-time Freight and other transportation costs billed to customers are recorded gross within revenue and cost of goods sold. Non-steel by-products by-products by-products by-products by-products. The Company has pricing latitude in revenue arrangements and is also exposed to inventory and credit risks. The Company offers industry standard payment terms that typically requires payment from customers 30 days after title and control transfers. |
Government funding | Government funding The benefit of Government funding is not recognized until there is reasonable assurance that the Company will comply with the conditions attaching to it and that the funding will be received. Benefits related to Government funding in the form of low interest rate loans, interest free loans and grants for items of capital are presented in the consolidated statements of financial position as an offset to the carrying value of the property, plant and equipment to which the benefits relate. In the case of low interest rate loans and interest free loans, the benefit is calculated as the difference between the fair value amount of the low interest rate loan or the interest free loan and the proceeds received. Claims under government grant programs related to income are recorded within the consolidated statements of net income as a reduction of the related item the grant is intended to offset, in the period in which the eligible expenses were incurred or when the services have been performed. |
Research | Research Research costs are expensed as incurred, due to the nature of the projects. Where government incentives in the form of investment tax credits and grants are received for research projects initiated by the Company for its own purposes, these incentives are deducted from the applicable category of expenditures. |
Finance cost | Finance cost Finance cost is comprised of interest expense on borrowings, amortization of issuance costs, and accretion of environmental liabilities. Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are recognized in profit or loss using the effective interest method. Actuarially determined interest costs related to the defined benefit pension obligation and the other post-employment benefit obligation are recorded respectively as components of the carrying amount of the accrued pension liability and the accrued other post-employment benefit obligation. |
Taxation | Taxation Current and deferred income tax are recognized in net income, except when they relate to items that are recognized in other comprehensive income (loss) or directly in equity, in which case, the current and deferred income tax are also recognized in other comprehensive income (loss) or directly in equity, respectively. Current tax The current tax expense is based on taxable income for the year. Taxable income differs from net income before taxes as reported in the consolidated statements of net income because of items of income or expense that are taxable or deductible in other years and items that are never taxable or deductible. The Company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the end of the reporting period. Deferred income tax Deferred income tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable income. Deferred income tax liabilities are generally recognized for all taxable temporary differences. Deferred income tax assets are generally recognized for all deductible temporary differences to the extent that it is probable that taxable income will be available against which those deductible temporary differences can be utilised. The carrying amount of deferred income tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no longer probable that sufficient taxable income will be available to allow all or part of the asset to be recovered. Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the asset is realised or the liability is settled, based on tax rates and tax laws that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred income tax assets and liabilities reflects the tax consequences, based on management’s expectation at the end of the reporting period, that would follow from the recovery or settlement of the carrying amount of its assets and liabilities. |
Share-based payment | Share-based payment The Company provides certain employees with long-term incentive awards. Equity-settled share-based payments to employees and others providing similar services are measured at the fair value of the equity instruments at the grant date. The fair value includes the effect of market based vesting conditions but excludes the effect of performance conditions. Details regarding the determination of the fair value of equity-settled share-based transactions are set out in Note 34. The fair value determined at the grant date of the equity-settled share-based payments is expensed on a straight-line basis over the expected vesting period, which is determined based on the Company’s expected timing on meeting the performance condition. The impact of the revision of the original estimates, if any, is recognized in profit or loss such that the cumulative expense reflects the revised estimate, with a corresponding adjustment to equity. For cash-settled share-based payments, a liability is recognized for the goods or services acquired, measured initially at the fair value of the liability. At each reporting date until the liability is settled, and at the date of settlement, the fair value of the liability is remeasured, with any changes in fair value recognized in profit or loss for the year. |
Comprehensive Income (Loss) | Comprehensive Income (Loss) Other comprehensive income (loss) (“OCI”) includes foreign exchange gain on translation to the Company’s presentation currency from the US Dollar functional currency. OCI includes actuarially determined gains and losses on post employment benefits offered to certain employees and the effect of any limits applied to the defined benefit asset. OCI also includes unrealized loss on cash flow hedge reserve. Comprehensive income is composed of net income and OCI. Accumulated OCI is a separate component of Shareholders’ Equity which includes the accumulated balances of all components of OCI which are recognized in comprehensive income but excluded from net income. |
