FORWARD-LOOKING STATEMENTS

This annual report on Form 40-F (this “Annual Report”) of Algoma Steel Group Inc. (the “Company”) includes or incorporates by reference “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 and “forward-looking information” under applicable Canadian securities legislation (collectively, “forward-looking statements”), that are subject to risks and uncertainties. These forward-looking statements include information about possible or assumed future results of the Company’s business, financial condition, results of operations, liquidity, plans and strategic objectives, the Company’s expectation to pay a quarterly dividend, the expected timing of the EAF (as defined below) transformation and the resulting increase in raw steel production capacity and reduction in carbon emissions. In some cases, you can identify forward-looking statements by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “pipeline,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result” or the negative of these terms or other similar expressions. In addition, any statements that refer to expectations, intentions, projections or other characterizations of future events or circumstances contain forward-looking information. Statements containing forward-looking information are not historical facts but instead represent management’s expectations, estimates and projections regarding future events or circumstances. In addition, the Company’s business and operations involve numerous risks and uncertainties, many of which are beyond the Company’s control, which could result in our expectations not being realized or otherwise materially affect the Company’s financial position, financial performance and cash flows. Although management believes that expectations reflected in forward-looking statements are reasonable, such statements involve risks and uncertainties and should not be regarded as a representation by the Company or any other person that the anticipated results will be achieved. The Company cautions you not to place undue reliance upon any such forward-looking statements, which speak only as of the date they are made. The Company’s forward-looking statements are not guarantees of future performance, and actual events, results and outcomes may differ materially from our expectations suggested in any forward-looking statements due to a variety of factors, including, among others, those set forth in the section entitled “Risk factors” in the Company’s annual information form for the year ended March 31, 2024 (the “AIF”), which is filed as Exhibit 99.1 to this Annual Report. Although it is not possible to identify all of these factors, they include, among others, the following:

• future financial performance;

• future cash flow and liquidity;

• future capital investment;

• the Company’s ability to operate the business, remain in compliance with debt covenants and make payments on the Company’s indebtedness, with a substantial amount of indebtedness;

• restrictive covenants in debt agreements limit the Company’s discretion to operate the business;

• significant domestic and international competition;

• macroeconomic pressures in the markets in which the Company operates;

• increased use of competitive products;

• a protracted fall in steel prices resulting in reduced revenue and/or impairment of assets;

• excess capacity, resulting in part from expanded production in China and other developing economies;

• low-priced steel imports and decreased trade regulation, tariffs and other trade barriers;

• protracted declines in steel consumption caused by poor economic conditions in North America or by the deterioration of the financial position of the Company’s key customers;

• increases in annual funding obligations resulting from the Company’s under-funded Pension Plans and Wrap Plan (each as defined in the AIF);

• supply and cost of raw materials and energy;

• impact of a downgrade in credit rating, including on access to sources of liquidity;

• currency fluctuations, including an increase in the value of the Canadian dollar against the U.S. dollar;

• environmental compliance and remediation;

• unexpected equipment failures and other business interruptions;

• a protracted global recession or depression;

• changes in or interpretation of royalty, tax, environmental, greenhouse gas, carbon, accounting and other laws or regulations, including potential environmental liabilities that are not covered by an effective indemnity or insurance;

• risks associated with existing and potential lawsuits and regulatory actions against the Company;

• impact of disputes arising with our partners;

• the Company’s ability to implement and realize its business plans, including its ability to complete the transition to electric arc furnace (“EAF”) steelmaking on time and at its anticipated cost;

• the Company’s ability to operate the EAF;

• expected increases in liquid steel capacity as a result of the transformation to EAF steelmaking;

• expected cost savings associated with the transformation to EAF steelmaking;

• expected reduction in carbon dioxide emissions associated with the transformation to EAF steelmaking, including with respect to the impact of such reduction on the Federal SIF EAF Loan (as defined in the AIF) and carbon taxes payable;

• the risks that higher cost of internally generated power and market pricing for electricity sourced from the Company’s current grid in Northern Ontario could have an adverse impact on the Company’s production and financial performance;

• the risks that indigenous groups’ claims and rights to consultation and accommodation may affect the Company’s ability to complete the EAF Transformation (as defined in the AIF);

• access to an adequate supply of the various grades of steel scrap at competitive prices;

• the risks associated with the steel industry generally;

• economic, social and political conditions in North America and certain international markets;

• changes in general economic conditions, including ongoing market uncertainty and global geopolitical instability;

• risks associated with inflation rates;

• risks inherent in the Company’s corporate guidance;

• failure to achieve cost and efficiency initiatives;

• risks inherent in marketing operations;

• risks associated with technology, including electronic, cyber and physical security breaches;

• construction risks, including delays and cost overruns;

• the Company’s ability to enter into contracts to source steel scrap and the availability of steel scrap;

• the availability of alternative metallic supply;

2

• the Company’s expectation to declare and pay a quarterly dividend;

• the limited functionality of the coke oven batteries as they remain unstable and not fully operational

• business interruption or unexpected technical difficulties, including impact of weather;

• counterparty and credit risk;

• labor interruptions and difficulties; and

• changes in the Company’s credit ratings or the debt markets.

The preceding list is not intended to be an exhaustive list of all of the Company’s forward-looking statements. The forward-looking statements are based on the Company’s beliefs, assumptions and expectations of future performance, taking into account the information currently available to it. These statements are only predictions based upon the Company’s current expectations and projections about future events. There are important factors that could cause the Company’s actual results, levels of activity, performance or achievements to differ materially from the results, levels of activity, performance or achievements expressed or implied by the forward-looking statements. In particular, you should consider the risks provided under “Risk Factors” in the AIF, filed as Exhibit 99.1 to this Annual Report.

You should not rely upon forward-looking statements as predictions of future events. Although the Company believes that the expectations reflected in the forward-looking statements are reasonable, the Company cannot guarantee that future results, levels of activity, performance and events and circumstances reflected in the forward-looking statements will be achieved or will occur. Despite a careful process to prepare and review the forward-looking information, there can be no assurance that the underlying assumptions will prove to be correct. Except as required by law, the Company undertakes no obligation to update publicly any forward-looking statements for any reason after the date of this Annual Report, to conform these statements to actual results or to changes in the Company’s expectations.

3

B. Management’s annual report on internal control over financial reporting. The Company’s management, including the CEO and CFO, is responsible for establishing and maintaining effective internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of March 31, 2024, based on the criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation.

EXHIBIT 97

Algoma Steel Group Inc.

CLAWBACK POLICY

The Board of Directors (“Board”) of Algoma Steel Group Inc. (the “Company”) has adopted this Policy in accordance with Nasdaq listing requirements.

A. Application of Policy

This Policy applies in the event of any restatement (“Restatement”) of the Company’s financial results due to its material non-compliance with financial reporting requirements under the securities laws, including both big “R” restatements (to correct a material error to previously issued financial statements) and little “r” restatements (to correct errors that are not material to previously issued financial statements, but would result in a material misstatement if (a) the errors were left uncorrected in the current report or (b) the error correction was recognized in the current period). This Policy does not apply to restatements that are not caused by non-compliance with financial reporting requirements, such as, but not limited to, a retrospective: (1) application of a change in accounting principles; (2) revision to reportable segment information due to a change in the structure of the Company’s internal organization; (3) reclassification due to a discontinued operation; (4) application of a change in reporting entity, such as from a reorganization of entities under common control; (5) adjustment to provision amounts in connection with a prior business combination; and (6) revision for stock splits, reverse stock splits, dividends or other changes in capital structure (collectively the “Restatement Exclusions”).

B. Executive Officers Subject to the Policy

The “executive officers” of the Company are covered by this Policy. This includes the Company’s current or former Chief Executive Officer, President, Chief Financial Officer, Chief Human Resources Officer, Chief Legal Officer, Chief Accounting Officer or Controller, any Vice-President of the Company in charge of a principal business unit, division or function, and any other current or former officer or person who performs a significant policy-making function for the Company, including executive officers of Company subsidiaries or the Company’s parent (the “Executive Officers”). All of these Executive Officers are subject to this Policy, even if an Executive Officer had no responsibility for the financial statement errors which required restatement.

C. Compensation Subject to the Policy

This Policy applies to any incentive-based compensation received by an Executive Officer during the period (the “Clawback Period”) consisting of any of the three fiscal completed years immediately preceding:

• the date that the Company’s Board (or Audit Committee) concludes, or reasonably should have concluded, that the Company is required to prepare a Restatement, or

• the date that a court, regulator, or other legally authorized body directs the Company to prepare a Restatement.

This Policy covers all incentive-based compensation (including any cash or equity compensation) that is granted, earned or vested based wholly or in part upon the attainment of any “financial reporting measure”. Financial reporting measures are those that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements and any measures derived wholly or in part from such financial information (including non- GAAP measures, stock price and total shareholder return). Incentive-based compensation is deemed “received” in the fiscal period during which the applicable financial reporting measure (as specified in the terms of the award) is attained, even if the payment or grant occurs after the end of that fiscal period. This Policy applies to all incentive-based compensation received on or after October 2, 2023.

Incentive-based compensation does not include base annual salary, compensation which is awarded based

solely on service to the Company (e.g. a time-vested award, including time-vesting stock options or restricted share units), nor does it include compensation which is awarded based on subjective standards, strategic measures (e.g. completion of a merger) or operational measures (e.g. attainment of a certain market share, shipment volume, productivity or environmental performance target).

D. Amount Required to be Repaid Pursuant to this Policy

The amount of incentive-based compensation that must be repaid (subject to the few limitations discussed below) is the amount of incentive-based compensation received by the Executive Officer that exceeds the amount of incentive-based compensation that otherwise would have been received had it been determined based on the Restatement (the “Recoverable Amount”). Applying this definition, after a Restatement, the Company will recalculate the applicable financial reporting measure and the Recoverable Amount in accordance with SEC and exchange rules. The Company will determine whether, based on that financial reporting measure as calculated relying on the original financial statements, an Executive Officer received a greater amount of incentive-based compensation than would have been received applying the recalculated financial measure. Where incentive-based compensation is based only in part on the achievement of a financial reporting measure performance goal, the Company will determine the portion of the original incentive-based compensation based on or derived from the financial reporting measure which was restated and will recalculate the affected portion based on the financial reporting measure as restated to determine the difference between the greater amount based on the original financial statements and the lesser amount that would have been received based on the Restatement. The Recoverable Amounts will be calculated on a pre-tax basis to ensure that the Company recovers the full amount of incentive-based compensation that was erroneously awarded.

In no event shall the Company be required to award Executive Officers an additional payment if the restated or accurate financial results would have resulted in a higher incentive compensation payment.

If equity compensation is recoverable due to being granted to the Executive Officer (when the accounting results were the reason the equity compensation was granted) or vested by the Executive Officer (when the accounting results were the reason the equity compensation was vested), in each case in the Clawback Period, the Company will recover the excess portion of the equity award that would not have been granted or vested based on the Restatement, as follows:

• if the equity award is still outstanding, the Executive Officer will forfeit the excess portion of the award;

• if the equity award has been exercised or settled into shares (the “Underlying Shares”), and the Executive Officer still holds the Underlying Shares, the Company will recover the number of Underlying Shares relating to the excess portion of the award (less any exercise price paid for the Underlying Shares); and

• if the Underlying Shares have been sold by the Executive Officer, the Company will recover the proceeds received by the Executive Officer from the sale of the Underlying Shares relating to the excess portion of the award (less any exercise price paid for the Underlying Shares).

The Board will take such action as it deems appropriate, in its sole and absolute discretion, reasonably promptly to recover the Recoverable Amount, unless the Compensation Committee determines that it would be impracticable to recover such amount because (1) the direct costs of enforcing recovery would exceed the Recoverable Amount, (2) recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder, or (3) if the recovery of the incentive-based compensation would violate the home-country laws of the Company. In connection with a determination pursuant to clause (1), the Company must have first made a reasonable and documented attempt at recovery and shall provide related documentation to Nasdaq. In connection with a determination pursuant to clause (2), the Company must obtain an opinion of counsel.

E. Additional Clawback Required by Section 304 of the Sarbanes-Oxley Act of 2002

In addition to the provisions described above, if the Company is required to prepare an accounting restatement due to the material noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under the securities laws, then, in accordance with Section 304 of the Sarbanes-Oxley Act of 2002, the Chief Executive Officer and Chief Financial Officer (at the time the financial document embodying such financial reporting requirement was originally issued) shall reimburse the Company for:

• any bonus or other incentive-based or equity-based compensation received from the Company during the 12-month period following the first public issuance or filing with the Commission (whichever first occurs) of such financial document; and

• any profits realized from the sale of securities of the Company during that 12-month period.

F. Crediting of Recovery Amounts

To the extent that subsections A, B, C and D of this policy (the “Rule 10D-1 Clawback Requirements”) would provide for recovery of incentive-based compensation recoverable by the Company pursuant to Section 304 of the Sarbanes-Oxley Act, in accordance with subsection E of this policy (the “Sarbanes-Oxley Clawback Requirements”), and/or any other recovery obligations (including pursuant to employment agreements, or plan awards), the amount such Executive Officer has already reimbursed the Company shall be credited to the required recovery under the Rule 10D-1 Clawback Requirements. Recovery pursuant to the Rule 10D-1 Clawback Requirements does not preclude recovery under the Sarbanes-Oxley Clawback Requirements, to the extent any applicable amounts have not been reimbursed to the Company.

G. General Provisions

This Policy may be amended by the Board from time to time. Changes to this Policy will be communicated to all persons to whom this Policy applies.

The Company will not indemnify or provide insurance to cover any repayment of incentive-based compensation in accordance with this Policy.

The provisions of this Policy apply to the fullest extent of the law; provided however, to the extent that any provisions of this Policy are found to be unenforceable or invalid under any applicable law, such provision will be applied to the maximum extent permitted, and shall automatically be deemed amended in a manner consistent with its objectives to the extent necessary to conform to any limitations required under applicable law.

This Policy is in addition to (and not in lieu of) any right of repayment, forfeiture or right of offset against any Executive Officer that is required pursuant to any other statutory repayment requirement (regardless of whether implemented at any time prior to or following the adoption of this Policy). Nothing in this Policy in any way detracts from or limits any obligation that those subject to it have in law or pursuant to a management, employment, consulting or other agreement with the Company or any of its subsidiaries.

All determinations and decisions made by the Board (or any committee thereof) pursuant to the provisions of this Policy shall be final, conclusive and binding on the Company, its subsidiaries and the persons to whom this Policy applies. Executive Officers (as defined above) are required to acknowledge that they have read this Policy annually. If you have questions about the interpretation of this Policy, please contact the Chief Financial Officer.

Description of the Business

Algoma is a fully-integrated steel producer of hot and cold rolled steel products, including coiled sheet and plate, strategically located on the Great Lakes in Sault Ste. Marie, Ontario, Canada. We are a leading flat-rolled steel producer in North America, one of Canada’s largest steel producers by volume and its only plate manufacturer, with a current liquid steel production capacity of an estimated 2.8 million tons per year. We supply customers with direct applications in the automotive, construction, energy, defense and manufacturing sectors.

Our liquid steel production facilities currently include two blast furnaces, Blast Furnace No. 6 (as defined herein) and Blast Furnace No. 7 (as defined herein), of which Blast Furnace No. 7 is currently operating as our principal source of liquid iron. We are in the process of a transition to EAF steelmaking, which we expect will ultimately replace our Blast Furnace No. 7 production capabilities and provide a number of benefits, including improved efficiency, reduced fixed costs, enhanced production capacity and significantly reduced carbon emissions. Construction of two EAFs is ongoing and the first furnace is expected to be completed during calendar year 2024 and commissioning anticipated to begin by the end of 2024. The second furnace is expected to be completed in the first half of 2025, with ramp-up and commissioning anticipated thereafter. Our idled Blast Furnace No. 6 could also provide operational flexibility, including the potential to provide hot metal (iron) as a direct feedstock into our EAFs if needed. We believe a restart of Blast Furnace No. 6 could be achieved within approximately six months, for an estimated C$60 - C$80 million investment.

In our downstream production processes, we manufacture a broad range of high-quality semi-finished and finished flat steel sheet and plate products. In 1995, approximately C$450 million was invested to construct our Direct Strip Production Complex (“DSPC”), which is our cornerstone asset and one of the world’s first hot strip mills coupling integrated continuous casting with hot rolling. In addition to the DSPC, we operate a discrete 106 inch-wide hot strip mill and 166 inch-wide plate rolling mill as a combination mill. We are investing in a modernization of our plate mill, which has allowed us to improve product quality and is anticipated to provide a plate capacity upgrade to 600,000 to 700,000 tons per year once completed in the second half of calendar year 2024. Once we complete the Plate Mill Modernization (as defined below) and EAF Transformation, we plan to shift the primary focus of our combination mill to high-quality plate products, thereby reducing production from our 106 inch-wide hot strip mill. As a result, after thorough consideration of the North American wide sheet and plate markets and our competitiveness in these markets, we have commenced the process of exiting the wide sheet business and idling the 106” sheet mill by the completion of this fiscal year. We believe this will allow us to optimize margins by the sale of premium quality plate products, where we build on our market position as the only domestic discrete plate producer in the Canadian market.

Our coil sheet steel products include a wide variety of widths, gauges and grades, and are available in unprocessed form as well as with value-added temper processing for hot rolled coil (“HRC”), annealed and full hard cold-rolled coil, hot-rolled pickled and oiled products, floor plate and cut-to-length products. Primary end-users of our sheet products include service centers, automotive, manufacturing, construction and tubular industries. Sheet steel products represented approximately 87% of our total steel shipment volumes in our fiscal year ended March 31, 2024.

Our plate steel products consist of various carbon-manganese, high-strength and low-alloy grades, and are sold in the as-rolled condition as well as subsequent value-added heat-treated conditions. The primary end-user of our plate products is the fabrication industry, which uses our plate products in the manufacture or construction of railcars, buildings, bridges, off-highway equipment, storage tanks, ships, military applications (including armored plate), large diameter pipelines and power generation equipment. Plate steel products have represented approximately 13% of our total steel shipment volumes for the fiscal year ended March 31, 2024.

Strategy, EAF Transformation and Other Key Investments

Our corporate strategy aims to maximize stakeholder value through strategic investments in our business that provide and enhance a sustainable competitive cost position. Key investments include our EAF Transformation, the ongoing modernization of our plate mill and our completed Ladle Metallurgy Furnace No. 2 (“LMF2”) investment. Through these strategic initiatives, we are ensuring the long-term success and growth of our business. We anticipate that these investments will enhance our leading presence in the Canadian market and allow the Company to actively contribute to a more sustainable and environmentally responsible steel industry. In addition to the above, we are committed to fostering an entrepreneurial culture within our organization. This culture will be rooted in values such as safety, productivity, and a caring attitude, which will guide our decisions and interactions. Safety will be our top priority, ensuring the well-being of our employees and stakeholders at all times. Productivity will be pursued through a culture of continuous improvement, empowering our teams to innovate and optimize processes, resulting in increased efficiency and operational excellence. Lastly, a caring attitude will permeate our organization, promoting a supportive and inclusive environment where everyone feels valued and respected. By nurturing this entrepreneurial culture, we aim to foster a strong sense of ownership and accountability among our employees, driving our business towards long-term success while prioritizing the well-being of our people and the communities we serve

EAF Transformation. On November 10, 2021, our board of directors authorized the Company to construct two state-of-the-art EAFs to replace our existing Blast Furnace No. 7 steelmaking operations (the “EAF Transformation”). The EAF Transformation is expected to reduce our carbon emissions by approximately 70%. EAF steelmaking is a method of producing steel by melting scrap metal and other metallic inputs using an electric arc, and is widely used in modern steel production. Our EAF steelmaking facility is being built on vacant land adjacent to our current steelmaking facility to mitigate disruption to current operations, and will be integrated into existing downstream equipment and facilities, thereby reducing capital expenditure requirements.

Vacuum Tank Degasser. The EAF Transformation also includes installation of vacuum tank degassing for steel used in plate products. Vacuum tank degassing offers several significant benefits for steel plate products, including reduced

- 7 -

hydrogen content crucial for improving the steel’s resistance to cracking and brittleness, improved cleanliness to reduce impurities and inclusions leading to better surface finish and enhanced mechanical properties, and enhanced homogeneity promoting a more uniform distribution of alloys within the steel to improve consistency and reduce localized variations in properties.

Ladle Metallurgy Furnace No. 2. The Company completed a new 2.1mm ton ladle metallurgy furnace in February 2021, which unlocked 100,000 tons of additional capacity and added advanced grades of steel to our product mix.

Plate Mill Modernization. In 2019, we undertook a plate mill modernization project (the “Plate Mill Modernization”). We plan to complete the Plate Mill Modernization in two phases and invest a total of approximately C$135million in the modernization. This strategic initiative is designed to enhance the capacity and quality of our discrete plate product line, which is a differentiated product capability and a key source of competitive advantage. The Plate Mill Modernization is expected to allow us to (i) satisfy higher product quality requirements of our customers with respect to surface and flatness, (ii) increase high strength capability with availability of new grades, (iii) enhance reliability of plate production with direct ship capability and (iv) increase overall plate shipment capacity through debottlenecking and automation.

The modernization process is comprised of two phases, the first being focused on quality and the second on productivity. The first phase was completed in 2022 and comprised of the installation and commissioning of a new primary slab de-scaler (to improve surface quality), automated surface inspection system (to detect and map surface quality), an in-line hot leveler (to improve flatness) and automation of the 166-inch plate mill (which expands our grade offering).

The second phase focuses on productivity enhancement and will be completed in two separate minor outages throughout 2024 to decrease commissioning risks and to provide for lesser impact to our customers. The Company has installed and is presently commissioning the inline dividing shear and plate piler. The first 20-day outage was successfully completed in April, 2024, and involved installation and commissioning upgrades of the new 4 HI DC drives, onboard descaling systems for the 2Hi roughing mill; mill alignment and work roll offset at the 4Hi mill; and new cooling beds coupling the plate mill and shear line, dividing shear, plate piler and automated marking machine. Work at the facility is now substantially complete and we expect any remaining minor items to be completed with other planned maintenance activities over the coming year.

Unique Production Process

We are the only integrated steel producer in North America to operate a DSPC line that converts liquid steel sourced from a blast furnace directly into coil. Our DSPC hot mill provides us with a cost advantage over the traditional integrated hot rolling manufacturing process. Current annualized production capacity of the DSPC complex is 2.3 million tons.

A hot strip mill coupled to direct casting can provide a significant competitive advantage in the steel industry. This technology integration eliminates the need for intermediate processes such as slab reheating and rolling. By leveraging the advantages of a hot strip mill coupled to direct casting, we achieve cost savings, improve operational efficiency, enhance product quality and reduce environmental impact. The DSPC is ideally designed to integrate into our new EAFs, and is expected to allow us to transform into a state-of-the-art mini mill production facility once the EAFs are commissioned and ramped-up.

The DSPC provides a competitive advantage, enabling us to offer superior products, meet customer needs more effectively and strengthen our position in the steel industry. This technology offers key advantages, including:

- 8 -

● Cost Efficiency: Direct casting eliminates the need for costly and time-consuming slab reheating processes. The continuous production method reduces energy consumption and operational costs associated with reheating furnaces, resulting in improved cost efficiency.

● Time Savings: By eliminating intermediate processes, a hot strip mill coupled to direct casting significantly reduces the production cycle time. This allows for faster turnaround and shorter lead times, giving us a competitive edge in meeting customer demands and achieving just-in-time delivery.

● Improved Quality: Direct casting technology allows for better control over our steel products’ microstructure and mechanical properties. The continuous casting process results in improved product consistency and surface quality, reducing defects and enhancing the overall quality of our steel products.

● Environmental Benefits: The integration of direct casting minimizes the environmental impact of steel production by reducing energy consumption and greenhouse gas emissions. This aligns with sustainability goals and enhances our reputation as an environmentally responsible producer.

● Flexibility and Customization: With a hot strip mill coupled to direct casting, we are able adapt to market demands more efficiently. The continuous process enables quick changes in steel grades, sizes, and specifications, allowing for greater flexibility and customization options to meet customer requirements.

We are the only discrete plate producer in Canada, with current capacity of 350,000 to 400,000 tons per year and the potential to increase capacity to 600,000 to 700,000 tons per year upon completion of our Plate Mill Modernization program. We expect that completion of the plate modernization program may reduce Canada’s reliance on plate imports and positively impact the country’s trade balance in plate products.

Employment and Government Support

We are the largest employer in Sault Ste. Marie, Ontario. As of March 31, 2024, the Company had 2,844 full-time employees, of which approximately 95% are represented by two locals of the United Steelworkers Unions under two collective bargaining agreements expiring July 31, 2027. As a result of the Company’s good relationship with its unionized workforce, there has not been a work disruption in approximately 30 years, and we have achieved contract terms that are competitive to those achieved by our peers.

As a result of our significant contribution to the Canadian steelmaking industry, we benefit from strong federal and provincial government support in various forms. For example, to support political policies of the governments of Canada and Ontario, we have received financial support in the form of loans and grants, which have enabled us to undertake various capital expenditures to reinvest in the Company.

Environmental, Social and Governance

As part of our commitment to continue to augment our transparency and accountability on ESG, the Company published our inaugural ESG report (the “ESG Report”) in September 2023. Algoma aims to be a climate change leader and contributor toward a sustainable and environmentally responsible future for Canadian steel production. The report was designed to align with market-leading, investor-preferred ESG disclosure frameworks, such as the Sustainability Accounting Standards Board and the recommendations of the Task Force on Climate-related Financial Disclosures. The ESG Report will set out the Company’s ESG strategy, and its approach to mitigating ESG risks and capturing ESG opportunities, and provide an update on the Company’s ESG performance. We expect to publish our second annual report in August 2024.

Our Competitive Strengths

Strategically Located in Close Proximity to Customers and Suppliers

We are strategically located on Lake Superior with close proximity to key steel consuming regions of the United States (the U.S. Mid-West, U.S. Northeast) and Canada (Southern Ontario), allowing us to serve our customers at competitive costs, as well as to gain access to the supply of post-consumer steel scrap as a raw material. Approximately 70% of our customers are located within a 500-mile radius of our facility. Additionally, our location on the Great Lakes provides access to multiple modes of transportation, supporting our ability to negotiate competitive rates for inbound raw materials and outbound steel products. Our acquisition of the adjacent port facility as part of the Restructuring Transaction – the fourth largest Canadian port on the Great Lakes by volume, handling nearly 450 vessels a year and over 4.5 million tons of shipments – facilitated access to low-cost transportation across the Great Lakes and secured our distribution network.

We also have the option to pursue rail transportation from certain iron ore mines using well-established rail links, facilitating access to ore through the winter months when transport over the Great Lakes is less feasible. We sell steel products to a diverse base of approximately 200 customers across multiple sectors in North America, with no single customer accounting for greater than 14% of revenues. Our top ten customers accounted for approximately 51% of total revenue in the fiscal year ended March 31, 2024. Our geographic, sector and customer diversity reduces our exposure to shifts in demand. We have built strong customer relationships, with the average tenure for our top ten customers being between 20 and 25 years. Despite the U.S. tariffs imposed on Canadian steel producers on June 1,

2018, the Company was able to maintain its geographic mix with 60% of revenue for the fiscal year ended March 31, 2024 generated by our customers in the United States.

The following map illustrates the Company’s advantageous location at the tips of Lake Superior and Lake Huron, with ready access to iron ore from the Mesabi range, access to scrap metals anticipated to be sourced from the large industrial zones surrounding the Great Lakes (including Chicago, Detroit and Toronto), and favorable shipping costs to key industrial customers in the Midwestern United States and Greater Toronto Area.

Operations Designed to Provide Superior Product Quality and Serve Diversified Blue-Chip Customer Base in Attractive End Markets

Plate products accounted for 13% of shipments, hot rolled sheet for 79% and cold rolled sheet for 8% of shipments for the fiscal year ended March 31, 2024. Additionally, flexible union labor contracts allow us to optimize manpower allocation across the entire facility to meet changes in demand. Our facilities have the flexibility to produce varying product widths, gauges and strengths, which allows us to serve a broad customer base across various end markets, including service centers, automotive, manufacturing, construction and tubular markets. Furthermore, our research and development investments support higher quality, lower cost products and drive a value proposition for customers.

- 11 -

Source: Company information.

We serve a diverse and blue-chip customer base with over 200 customers across multiple industries in North America. No single customer makes up more than 14% of our sales. In our fiscal year ended March 31, 2024, 43% of our sales were to transportation customers (two-thirds of which were in the automotive market), 30% of sales were to manufacturing and construction markets, 10% of sales were to tubular markets (primarily serving oil and gas customers), and only 17% of sales were sold to distribution customers. Our geographical sales are divided between the United States and Canada, serving high-quality industrial customers generally located on or near the Great Lakes given our logistical advantages. While the geographical sales mix varies year-by-year depending on relative demand, in the fiscal year ended March 31, 2024, 60% of our products were sold into the United States market while 39% were sold within Canada.

- 12 -

Low Cost Position Underpinned by Advantageous Raw Material Contracts

Our largest input cost in the steelmaking process is iron ore, which we purchase under separate supply contracts with Cliffs (“Cliffs”) and United States Steel Corporation (“U.S. Steel”). We believe multi-sourcing our iron ore improves the stability in our raw material procurement and mitigates the supply risks for one of our critical raw materials. Taken together, the Company’s agreements with Cliffs and U.S. Steel are expected to provide for the supply of iron ore pellets through the close of the 2027 shipping season.

On October 2, 2023, we announced an extension of our iron ore contract with U.S. Steel, which is anticipated to cover the expected volumes of iron ore required to complete our transition from blast furnace to EAF steelmaking. The agreement with U.S. Steel is a two-year extension of the existing iron ore purchase contract, with an option to further extend for a third year solely at our discretion. U.S. Steel’s announced sale to Nippon Steel does not affect the extended agreement.

Flexible Cost Structure Positions Algoma to Generate Cash Flow Through-the-Cycle

The combination of a flexible cost structure and the ongoing reduction in fixed costs positions Algoma to potentially generate positive cash flow through the steel economic cycle, including at HRC prices significantly lower than in the current pricing environment.

Legacy Liabilities Sustainably De-Risked from CCAA Process

On November 9, 2015, the Company’s predecessor, Old Steelco (as defined herein), filed for creditor protection in Canada under the CCAA (as defined herein) and in the United States under Chapter 15 of Title 11 of the United States Bankruptcy Code. On November 30, 2018, pursuant to the Restructuring Transaction approved by the court in the CCAA proceedings, Opco completed the purchase of substantially all of the operating assets and some of the liabilities of Old Steelco and its affiliates. As part of the Restructuring Transaction, we achieved transformational improvements in our capital structure, pension funding obligations and environmental liabilities. See “Risk Factors - Any increases in annual funding obligations resulting from our under-funded Pension Plans and Wrap Plan could have a material adverse effect on us” for additional details regarding the pension plans assumed by Algoma as part of the Restructuring Transaction.

For example, in connection with the Restructuring Transaction, the Company entered into an agreement (the “LEAP Agreement”) with the Province of Ontario, as represented by the Minister of the Environment, Conservation and Parks (“MECP”) which addresses legacy environmental issues at the Company’s main site in Sault Ste. Marie. The MECP provided a release in our favor from any obligations under applicable environmental laws relating to legacy environmental issues at our Sault Ste. Marie site with respect to the historical soil, groundwater and sediment contamination at our facility. Steelmaking activities have occurred at the Company’s site since 1901 and before the adoption of modern environmental best practices. Pursuant to the LEAP Agreement, we agreed to fund C$3.8 million per year for 21 years to a financial assurance fund, established to fund expenses relating to approved legacy environmental remediation and other projects, and provided a C$10 million letter of credit to the MECP to provide financial assurance for these obligations.

Sales and Marketing

The principal markets for our products are steel service centers, the automotive industry, manufacturing and construction. We market our sheet and plate products direct to end-users and also through distributors in Canada and the United States. We are focused on leveraging various competitive attributes of our process and product technologies to improve market and customer segmentation. We pursue the development of applications and markets for our high strength and light gauge products to respond to application design factors. We are also focused on increasing the Company’s product portfolio to include more value-added products.

- 14 -

As part of our strategy to increase direct sales to end users of plate products, we have reduced the percentage of products sold through service centers. However, due to the nature of the market and the customers for such products, we continue to sell through service centers.

The Company pursues a diversified market and customer strategy to manage earnings volatility in the North American steel market. It is critical that a North American steel producer provide products to customers in all sectors of the economy given the industry dynamics, strong competition and global overcapacity. Focusing on more than one commodity to one sector is key to ensuring earnings stability through the business cycle and achieving greater stability in economic downturns. The Company believes it has strong customer loyalty which helps it to manage through the volatility of the steel pricing cycle.

Competition

There has been a substantial increase in global steel capacity, particularly in China, which has become the largest producer and consumer of steel in the world.

A significant slowdown in domestic Chinese growth and/or increases in capacity that exceed consumption rates in China could result in surplus steel being exported to world markets. In addition, an economic downturn that affects demand for our products or an increase in the strength of the U.S. dollar or Canadian dollar relative to other currencies could increase imports. It is, therefore, possible that more unfairly priced imports could enter the North American markets at a future date, which could result in domestic price erosion, which would adversely affect our ability to compete, or generate revenue and reduce profitability.

We compete with numerous foreign and domestic steel producers, primarily from integrated producers, like ourselves, as well as EAF producers. We primarily compete with other steel producers based on the delivered price of finished steel products to customers. EAF producers typically require lower capital expenditures for construction and maintenance of facilities, and may have lower total employment costs. However, these competitive advantages may be reduced or eliminated when scrap prices are high.

- 15 -

Although freight costs for steel can often make it uneconomic for distant steel producers to compete with us, to the extent that they have lower cost of sales resulting from lower labor, raw material or energy costs or from government subsidies, they may be able to successfully compete. Although we are continually striving to improve our operating costs, we may not be successful in achieving labor, raw material and energy cost improvements or gaining operating efficiencies that may be necessary to remain competitive on a global scale.

Our competitive position is positively affected by lower incoming raw material transportation costs as well as lower marine outbound costs of finished products than those of other Canadian producers. Our position on the Great Lakes provides us with access to lower cost modes of transportation for our inbound raw materials and outbound steel products. Approximately 70% of our customers are located within a 500-mile radius of our facility in key steel consuming regions of the Midwest and Northeast United States and southern Ontario, allowing us to service our customers at competitive costs. In accordance with common industry practice, we may from time to time assume additional shipping costs when selling outside of our local geographic area in order to provide competitive pricing.

Trade

Our business has historically been affected by “dumping” – the selling of steel into Canadian or U.S. markets at prices below cost or below the price prevailing in a foreign company’s domestic market. Dumping may result in injury to steel producers in Canada or the U.S. in the form of suppressed prices, lost sales, lower profits and reductions in production, employment levels and the ability to raise capital. Some foreign steel producers are owned, controlled or subsidized by foreign governments. Decisions by these foreign producers to continue production at marginal facilities may be influenced to a greater degree by political and economic policy considerations than by prevailing market conditions and may further contribute to excess global capacity.

Successful industry trade cases over the past several years have had an impact on import levels as well.

The United States-Mexico-Canada (USMCA) trade agreement went into effect in July 2020. The agreement has several provisions that we believe will benefit the steel industry, including requiring that higher levels of a vehicle’s content, including steel, be produced in North America for a vehicle to qualify for zero tariffs, and that 70% of the steel used in vehicles be melted and poured in North America. There are also provisions addressing currency manipulation and state-owned enterprises.

Although trade legislation to limit dumping has had some success, it may be inadequate to prevent future unfair import pricing practices which individually or collectively could materially adversely affect our business. If Canadian or U.S. trade laws are weakened, an increase in the market share of imports into the U.S. and Canada may occur, which would have a material adverse effect on our business and financial performance.

There remains in place anti-dumping findings covering imports of (i) hot rolled sheet into Canada from Brazil, China and India and into the United States from Russia, China, India, Indonesia, Taiwan, Thailand, Ukraine, Australia, Japan, South Korea, Netherlands, Turkey and United Kingdom, among other countries, (ii) cold rolled sheet into Canada from China, South Korea and Vietnam and into the United States from Brazil, China, India, Japan, South Korea and United Kingdom, and (iii) hot rolled plate into Canada from China, , Bulgaria, Czech Republic, Romania, South Korea, Italy, Brazil, Japan, Denmark, Indonesia, Taiwan and Germany and into the United States from China, Russia, Ukraine, India, Indonesia, South Korea, Austria, Belgium, Brazil, France, Germany, Italy, Japan, South Africa, Taiwan, and Turkey

New trade cases in other jurisdictions are being considered to cover such exports. This and the potential for such exports to continue to displace hot rolled sheet product exports from other countries in markets worldwide may result in large quantities of hot rolled sheet products being exported into Canada and United States. The Company will

- 16 -

continue to monitor imports of competing steel products into its customer markets and take appropriate action, including filing complaints, where such actions are warranted.

Information systems

Our information technology landscape supports a high level of business automation across three distinct segments of business processes: management decision systems, manufacturing execution/scheduling systems and process control systems. Our management decision systems, including the full order-to-cash cycle, are running on the SAP (Windows/Oracle) platform. Our manufacturing execution/scheduling systems run on the IBM mainframe environment. Our process control systems run on Windows, Vax, and Honeywell environments. Our infrastructure includes a LAN/WAN data network, desk/mobile phone services, approximately 100 servers, approximately 1400 PCs and two main datacenters (SAP at the Sault Ste. Marie, ON and Mainframe at Markham, ON). Daily incremental and full back-ups, including offsite replication and storage, are created for disaster recovery purposes.

Enterprise risk management

The Company employs an enterprise risk management (“ERM”) process to coordinate risk management among departments to manage the organization’s full range of risks as a whole. ERM offers a framework for effectively managing uncertainty, responding to risk and harnessing opportunities as they arise. A comprehensive ERM framework consolidates and improves risk reporting to identify key risks that may affect the Company, quantify and manage them better, and implement the proper controls to eliminate or reduce the threat.

Algoma employs an enterprise risk management (ERM) program that proactively identifies and manages strategic risks to the organization. ERM follows a very distinct and ongoing process, where it actively identifies and reassesses the various strategic and major risks to ensure financial security for our business. The framework leverages systemization of the risk registers for prioritization and tracking; and applying effective mitigation strategies to manage risks. The ERM program extends its reach to evaluate strategic decisions and plans for the organization, as well as developing a risk culture to ensure longevity and sustainability of Algoma’s competitiveness.

Growth Strategies

In addition to our strategic goals focused on the ramp-up of our EAF Transformation and other key investment projects, we are constantly focused on applying a forward-looking value-focused lens on growth, increasing our participation in key sustainable markets, generating a competitive return on capital, and meeting our financial and other obligations for all stakeholders.

We are committed to improving our quality, cost competitiveness and customer service, as well as developing a diverse organization to support our long-term success, while maintaining safety excellence and environmental stewardship as key performance objectives.

Continuous Margin Stability Enhancement and Cost Improvement. We are striving to continue reducing our costs and improving our operating performance. Cost improvements include maintenance effectiveness, operations reliability, operational cost reductions, workforce effectiveness, power efficiency improvements, process yield improvements, improvements in product quality and optimization of gas usage.

Capitalize on Low-Cost Growth Opportunities. Our goal is to continue enhancing our productivity and profitability through prudent capital investment projects, and we will continue to evaluate opportunities of this nature. The LMF2, which debottlenecked our process flow and the additional capacity that we anticipate to add with our Plate Mill Modernization, are strong examples of how we seek to deploy capital to high return projects.

- 17 -

Maintaining a Prudent Financial Policy. We are committed to maintaining a strong financial profile for the Company. Our management is focused on generating disciplined growth while maintaining a strong credit profile, limiting net long-term debt and enhancing liquidity. The Company seeks to maintain adequate cash and available liquidity throughout the seasonality in its business cycle.

Additionally, our capital allocation strategy is focused on low-cost growth opportunities to enhance the capabilities and low-cost operating position of our steel mill and related works. These investments include the development of our EAF and internal investments such as the LMF2 debottlenecking project and the Plate Mill Modernization.

Focus on Safety and Environmental Compliance. Management is focused on sustainable healthy and safe operations by engaging in projects to improve health and safety, including machinery and crane guarding upgrades and coke battery door and jamb cleaners. Since the year ended March 31, 2015, we have reduced our lost time injury frequency rate, measured as lost time days per 200,000 hours worked, from an occurrence of 0.72 to approximately 0.03 for the fiscal year ended March 31, 2024. Health and safety remains paramount, and to further our efforts to improve our safety first culture, we are implementing an ISO 45001 Safety Management System.

We are committed to being responsible environmental stewards and encourage open communication and reporting to our communities with regard to our environmental performance. Through our participation in the Canadian Steel Producers Association, we have committed to pursue the aspirational goal of carbon neutrality by 2050. We continue to evaluate and pursue strategies to both meet this goal and maintain our competitiveness, including through the modernization of our existing facilities and/or the adoption of other technologies such as less carbon-intensive iron making or EAF steelmaking. We estimate that the transition to EAF steelmaking will result in a reduction of 3.0 million tonnes of CO2 emissions per year, representing a 70% reduction to current emissions levels with a goal of eliminating all coal use in our steelmaking operations over time, which we believe will allow us to become one of the greenest producers in North America and reduce the potential impact of the Canadian carbon tax regime on our business.

All of our facilities are qualified under the global ISO 14001 Environmental Management System Standard. We are supporting open dialogue on environmental issues with the community by establishing community outreach initiatives and ensuring frequent reporting on our environmental performance. For example, we have established a Community Liaison Committee as a forum for exchanging relevant environmental information with the public, conducting meetings on a monthly basis and publishing meeting notes on our website.

The Company instituted an environmental community liaison committee (“CLC”) to solicit representation from community organizations, agencies and public bodies, with the objective of keeping the local community informed about the operations of our facilities in relation to environmental regulations in effect, and to keep the Company informed of any community concerns about the operations of our facilities.

The CLC also serves as a forum for dissemination, review and exchange of information related to the environmental impact of our facilities. In order to ensure the objectives of the CLC are met, the Company provides information to the members as necessary on an ongoing basis.

Sources and Availability of Raw Materials

Steel production requires the use of large volumes of bulk raw materials and energy, in particular iron ore and coal, as well as energy, alloys, scrap, oxygen, natural gas, electricity and other inputs, the prices of which can be subject to significant fluctuation. The prices of iron ore and coal can vary greatly from period to period and our results have historically been impacted by movements in coal and iron ore prices. Iron ore and coal prices have been volatile in recent years.

- 18 -

Iron ore

See above under “Competitive Strengths - Low Cost Position Underpinned by Advantageous Raw Material Contracts” for information regarding our iron ore supply contracts.

Scrap Metal and Iron Units

On October 27, 2021, we announced that we had entered into a joint venture with Giampaolo Group Inc., the parent company of Triple M Metal LP and one of North America’s largest privately owned ferrous and non-ferrous metal recycling companies, establishing a jointly owned company known as ATM Metals Inc. The new entity sources prime scrap metal and other iron units to meet the Company’s business needs, including in connection with its transformation to EAF steelmaking.

Coal

The Company’s procurement team has worked with the operations team to develop a desired coal mix with reduced total volatile matter to produce more coke, which is stronger, creating less degradation and less gas. Coal is sourced from mines in Central Appalachia. Annual contracts have been set up with four suppliers which are incumbents for the past several years.

Coke

Our internal coke batteries produce the majority of our coke requirements for the Blast Furnace No. 7. Additional coke is purchased as required under contract or from the spot market.

Other raw materials

We purchase limestone, alloys and other raw materials for our manufacturing operation at what we believe to be competitive prices. We generate half of our scrap requirements internally and the balance is purchased from third parties, primarily from regional sources where we have a pricing advantage over other markets due to our proximity to the suppliers.

Energy

We purchase all of our natural gas from independent suppliers at market pricing. From time to time, we may use forward contracts over three- to twelve- month periods, mainly for peak winter months (January through March) to manage exposure to natural gas price changes. Currently, we do not have any fixed price natural gas commodity contracts in place. We do have fixed price contracts in place in relation to natural gas transportation.

The Company sources approximately 50% of its electricity needs internally and under a supply agreement with the operator of a low-cost cogeneration facility. We also obtain electricity from the Independent Electricity System Operator in Ontario and obtain electricity rebates under the Northern Industrial Electricity Rate program.

Oxygen is supplied by Linde Canada Inc. through a supply agreement that extends to mid-2026.

Government Regulation

The Company’s environmental policy is to conduct our business in a manner that ensures the Company and its personnel act reasonably and responsibly with respect to the protection of the environment. Where appropriate, we

- 19 -

have introduced environmental accountability to all employees. Activities that may have an impact on the natural environment have been identified and managed through the implementation of our ISO14001 compliant environmental management system. Our Environment Department regularly reviews and audits our operating practices to monitor compliance with our environmental policies and legal requirements.

The Company is required to comply with a stringent and evolving body of federal, provincial and local environmental laws concerned with, among other things, emissions into the air, carbon and greenhouse gas emissions, discharges to surface and ground water, the investigation and remediation of contaminated property, noise and odor control, waste management, recycling and disposal. Significant expenditures could be required for compliance with current or future laws or regulations relating to environmental compliance and remediation.

In the United States and Canada, certain environmental laws and regulations impose joint and several liabilities on certain classes of persons for the costs of investigation and remediation of contaminated properties. Liability may attach regardless of fault or the legality of the original management or disposal of the substance or waste. Some of our current and former facilities have been in operation for many years and, over such time, have used substances and disposed of wastes that may require investigation and remediation. The Company could be liable for the costs of such investigations and remediation. Costs for any remediation of contamination, on or off site, whether known or not yet discovered, or to address other issues relating to waste disposal, mine closure, emissions into the air or water, or the storage of materials, could be substantial and could have an adverse effect on our operating results.

In 2021, the Company became subject to the Canadian federal Output Based Pricing System (“OBPS”) for emissions, which requires payment for emissions above the OBPS benchmarks from the previous calendar year. In 2022, there was a transition from the federal OBPS to the Ontario Emissions Performance Program (“EPS Program”) for GHG emitters in Ontario. Compliance obligations for CY2023 are estimated at approximately C$14.6 million and payment is due by December 15th 2024. Provincial regulatory developments are currently underway for the 2023-2030 compliance periods to reflect Algoma’s transformation to EAF steelmaking and the associated GHG emission reduction that this project is expected to achieve.

See “Risk Factors – Increased regulation associated with climate change and greenhouse gas emissions could impose significant additional costs on our operations.”

The Company is required to implement plans and measures to reduce the amount of sulphur dioxide emitted from the combustion of coke oven gas by-product in accordance with the Notice issued under subsection 56(1) of CEPA. Algoma will be taking an alternative approach to reduce SO2 through its transition to electric arc steelmaking, which will see the elimination of cokemaking from Algoma’s operations. Algoma has provided a pollution prevention plan that reflects this alternative approach to reduce SO2 which has been deemed an acceptable approach to comply with CEPA. Similarly, in order to align with new provincial legislation related to SO2, Algoma has applied for a Site-Specific Standard that includes an action plan to reduce SO2 that reflects the progressive facility shutdown.

See “Risk Factors—Environmental compliance and site remediation obligations could result in substantially increased costs and could materially adversely affect our competitive position.

On October 18, 2019, there was a rupture of a steam drain line which was located below an electrical room in our cokemaking by-products plant (“BP”), which resulted in a loss of power to the BP. In accordance with our emergency procedures, the coke oven gas bleeders were lit to flare the coke oven gas. Additionally, the loss of power caused the cokemaking south raw liquor tank and the tar running tanks to overflow. Raw liquor was conveyed to the main water filter plant (“MWFP”) via a sewer located in the BP. This resulted in effluent exceedances at the MWFP for phenol, ammonia and total cyanide and a toxicity failure for rainbow trout.

- 20 -

On June 9, 2022, 460 gear oil was released from Algoma’s MWFP to the St. Mary’s River as a result of a spill that occurred during the night shift in the Plate & Strip Mill. The MECP and Environment and Climate Change Canada (“ECCC”) have initiated a joint investigation against the Company, which is ongoing. In addition, in connection with the January 20, 2024 structural collapse, a quantity of effluent (primarily raw cooling liquor) left our site and entered the adjacent waterway. We believe that the water-related environmental release was fully contained by the evening of January 20, with most of the effluent being contained on-site. As a result, we currently believe that there is a low risk of impact to the adjacent waterway. We remain in contact with regulatory authorities, including the MECP and ECCC, which are reviewing the incident. To date, we have not received any orders or notices of offense pursuant to environmental laws in Canada or the United States, but may in the future be subject to orders, offenses, penalties, fines or other negative consequences as a result of this incident, which may have an adverse effect on our business, financial condition or results of operations. The economic impact of this incident remains unknown. We are still assessing the impact of this incident, but such incident may subject us to the liabilities described above. In connection with this incident and similar incidents that may occur from time to time, we may need to make significant capital and operating expenditures to detect, repair and/or control discharges or to perform certain corrective actions to meet the conditions of the permits issued pursuant to applicable environmental laws.

See “Risk Factors – All of our operations are currently conducted at one facility using one blast furnace and are subject to unexpected equipment failures and other business interruptions” for further details.

RISK FACTORS

The following information is a summary only of certain risk factors and is qualified in its entirety by reference to, and must be read in conjunction with, the detailed information appearing elsewhere in this Annual Information Form. These risks and uncertainties are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us, or that we currently deem immaterial may also impair our business operations. If any of those risks actually occur, our business, prospects, financial position, financial performance and cash flow would suffer. The risks discussed below also include forward-looking statements, and our actual results may differ substantially from those discussed in these forward-looking statements. See “Cautionary Note Regarding Forward-Looking Information.”

Risks Related to our Business

Market and industry volatility could have a material adverse effect on our results. A protracted fall in steel prices, or any significant and sustained increase in the price of raw materials in the absence of corresponding steel price increases, would have a material adverse effect on our results.

The steel market is a cyclical commodity business with significant volatility in prices in response to various factors, including market demand, supply chain inventory levels, and imports. Factors specific to our business include a prolonged cyclical downturn in the steel industry, macroeconomic trends such as global or regional recessions and trends in credit and capital markets more generally. Market price volatility results in a high level of cash flow volatility with prolonged periods of negative cash flow. Steel prices are volatile and the global steel industry has historically been cyclical. During 2015, hot-rolled coil prices fell sharply by approximately $200/ton to $354/ton in the North American market, as a result of a significant increase in imports, driven primarily by the strengthening of the U.S. dollar against other currencies. In 2018, hot-rolled coil prices rose to over $900/ton over a short period then fell to under $500/ton in the fall of 2019. Hot-rolled coil prices recovered slightly, but fell to under $500/ton once again as a result of the COVID-19 pandemic and the related global economic slowdown. Since that low in 2020, hot-rolled coil prices rose to an all-time high of $1,958/ton by the end of 2021. Subsequently prices fell to below $1,000/ton by March 2022, and thereafter below $700/ton by December 2022. (CRU U.S. Midwest Hot-Rolled Coil). This volatility continued in 2023, when prices rose over $1,100/ton by April, fell back to $700/ton by October, and finally returned to over $1,000/ton by the end of the calendar year. Since then, the price has settled to approximately $750/ton in June 2024. These significant market price fluctuations also affect the cost of our raw material inputs and thus affect our bottom line. Any miscorrelation between finished product pricing and raw material inputs can have a material effect on our profitability. Protracted pricing or volume declines in the future would adversely affect our cash flow and ability to pay for our fixed costs, capital expenditures and other funding obligations.

Steel production also requires the use of large volumes of bulk raw materials, in particular iron ore and coal, as well as energy, alloys, scrap, oxygen, natural gas, electricity and other inputs, the prices of which can be subject to significant fluctuation. The prices of iron ore and coal can vary greatly from period to period and our results have historically been impacted by movements in coal and iron ore prices. Iron ore and coal prices have been volatile in recent years. In addition, to the extent that we have quoted prices to our customers and accepted customer orders for our products prior to purchasing necessary raw materials, we may be unable to raise the price of our products to cover all or part of the increased cost of the raw materials. Alternatively, we may be faced with having agreed to purchase raw materials and energy at prices that are above the then current market price or in greater volumes than required. The availability and prices of raw materials may also be negatively affected by new laws and regulations, allocation by suppliers, interruptions in production (including mining stoppages), accidents or natural disasters, changes in exchange rates, price fluctuations, the rate of inflation and the availability and cost of transportation. There can be no assurance that adequate supplies of electricity, natural gas, coal, iron ore, alloys, scrap and other inputs will be available in the future or that future increases in the cost of such materials will not adversely affect our financial performance.

- 22 -

Our largest input cost in the steelmaking process is iron ore, which we purchase under our supply contracts with Cliffs and U.S. Steel. On October 2, 2023, we announced that we had entered into a two-year extension of our existing iron ore supply contract with U.S. Steel, with an option to further extend for a third year solely at our discretion. We believe that our supply contracts will provide for the volumes of iron ore required to complete our transition from blast furnace to EAF steelmaking, but there can be no assurances that they will meet our needs or that we will be able to retain such long-term contracts.

We face significant domestic and international competition, and there is a possibility that increased use of competitive products could cause our sales to decline.

We compete with numerous foreign and domestic steel producers. Significant global steel capacity growth through new and expanded production in recent years has caused and may continue to cause capacity to exceed global demand, which has resulted and may result in lower prices and steel shipments. Some of our competitors have greater financial and capital resources than we do and continue to invest heavily to achieve increased production efficiencies and improved product quality. We primarily compete with other steel producers based on the delivered price of finished products to our customers. Our costs are generally higher than many foreign producers; however, freight costs for steel can often make it uneconomical for distant steel producers to compete with us. Foreign producers may be able to successfully compete if their higher shipping costs are offset by lower cost of sales.

Although we are continually striving to improve our operating costs, we may not be successful in achieving cost improvements or gaining operating efficiencies that may be necessary to remain competitive on a global scale.

The North American steel industry has, in the past, experienced lengthy periods of difficult markets due to increased foreign imports. Due to unfavorable foreign economic conditions, excess foreign capacity and a stronger U.S. dollar compared to global currencies, imports of steel products to U.S. and Canadian markets have occasionally reached high levels.

In addition, in the case of certain product applications, steel competes with a number of other materials such as plastic, aluminum, and composite materials. Improvements in the technology, production, pricing or acceptance of these competitive materials relative to steel or other changes in the industries for these competitive materials could cause our net sales to decline. There is ongoing research and technological developments with respect to the various processes associated with steel production which have the potential to reduce costs and improve quality and operational efficiency. Such research and technological developments could substantially impair our competitive position if other companies implement new technology that we elect not to implement or are unable to implement.

A number of steel producers have completed successful restructurings, through which they have made production improvements, achieved lower operating costs and been relieved of legacy obligations, including environmental and pension and retiree obligations. As a result, these entities may be able to operate with lower costs and cause us to face increased competition.

There has been a significant increase in new EAF steelmaking capacity commissioned in North America. EAF producers typically require lower capital expenditures for construction and maintenance of facilities, and may have lower total employment costs. In addition, the market pricing for our hot-rolled steel is more correlated to scrap steel as the main material for EAF producers. While our transformation to EAF steelmaking is currently in process, the EAF Transformation may never be completed or may only be completed after significant delays or at a substantially greater cost than anticipated. Failure to complete, or delays and/or cost overruns in completing the EAF Transformation could adversely affect our results of operations and ability to compete in our industry.

In addition, as a predominantly hot-rolled steel producer, our operations are focused on traditional hot rolled steel products rather than value-added or specialty steel products, which limits our ability to penetrate markets where

- 23 -

specialty or customized steel products are in demand. Hot-rolled steel, while essential in various industries, may have a narrower market compared to value-added steel products. This lack of differentiation in our product line can make it challenging to command premium prices for our products and also subjects us to lower financial margins compared to competitors who engage in further processing of hot-rolled steel into higher-value products. Increased competition in the hot-rolled steel market can also lead to pricing pressure on the products we do produce, which can have an adverse impact on our profit margins and lead to overall lower profitability in certain market conditions.

Macroeconomic pressures in the markets in which we operate, including, but not limited to, the effects of inflation, high interest rates and changes brought about by global health crises or pandemics may adversely affect consumer spending and our financial results.

To varying degrees, our products are sensitive to changes in macroeconomic conditions that impact pricing for consumer products and consumer spending. As a result, consumers may be affected in many different ways, including for example:

● whether or not they make a purchase;

● their choice of brand, model or price-point; and

● how frequently they upgrade or replace their products containing steel, such as appliances and automobiles.

Real GDP growth, consumer confidence, inflation, employment levels, oil prices, interest rates, tax rates, housing market conditions, foreign currency exchange rate fluctuations, costs for items such as fuel and food and other macroeconomic trends can adversely affect consumer demand for the products that we offer. Geopolitical conflicts and other issues around the world and how our markets are positioned can also impact the macroeconomic conditions and could have a material adverse impact on our financial results.

Our business operations and financial results are also subject to the risk of adverse impact due to significant disruption or curtailment in production, market demand, supply chains and advancement of capital projects in the event of a pandemic or similar global public health crisis, such as the COVID-19 pandemic. These events can lead to a range of adverse impacts on our operations, financial performance and prospects. Additionally, interventions and regulations implemented by government or health authorities to mitigate the spread of disease in the event of a pandemic or similar global health crisis, such as quarantine requirements, travel restrictions and lockdown measures, may prevent us from operating efficiently, or at all, and may further exacerbate the risk of adverse impacts on our business operations and financial results.

The Company may be subject to significant inflationary pressures and rising costs of the raw materials used to produce its products, which could have a material adverse impact on the Company’s business and results of operations.

From time to time the Company may be subject to significant inflationary pressures, in particular with respect to increases in commodity prices, including the price of iron ore, coal, electricity and natural gas, which are used in its manufacturing processes, as well as general increases in labor and other administrative costs. The timing and magnitude of any future increases in applicable commodity prices or other costs is uncertain at this time. Moreover, the Company is generally unable to pass through cost increases to customers because it sells its products at the prevailing market prices for steel products, which are determined in part by factors unrelated to the cost of underlying commodities. To the extent that such costs increase due to general inflationary pressures or otherwise, such increases could have a material impact on the Company’s business and results of operations.

- 24 -

Economic, social and political conditions in North America and certain international markets could adversely affect demand for the products we sell.

Sales of our products involve discretionary spending by consumers as well as our customers. Unfavorable economic conditions due to economic, social and political conditions in North America and certain international markets could result in less discretionary purchases by consumers, and discretionary project spending by our customers. Consumer spending may be affected by many economic and other factors outside of the Company’s control. Some of these factors include consumer disposable income levels, consumer confidence in current and future economic conditions, levels of employment, consumer credit availability, consumer debt levels, inflation, political conditions and the effect of weather, natural disasters, public health crises, decreased sales and widespread temporary closures. Adverse economic changes in any of the regions in which we sell our products could reduce consumer confidence and adversely affect our ability to sell our products.

A protracted global recession or depression would have a material adverse effect on the steel industry and therefore our business and operations.

Our activities and financial performance are affected by international, national and regional economic conditions. A significant and prolonged recession or depression in the United States, Canada or Europe, or significantly slower growth or the spread of recessionary conditions in emerging economies that are substantial consumers of steel (such as China, Brazil, Russia and India, as well as emerging Asian markets, the Middle East and the Commonwealth of Independent States) would exact a heavy toll on the steel industry. Financial weakness among substantial consumers of steel products, such as the automotive industry and the construction industry, or the bankruptcy of any large companies in such industries, would have a negative impact in market conditions. Protracted declines in steel consumption caused by poor economic conditions in North America or by the deterioration of the financial position of our key customers would have a material adverse effect on demand for our products and our operational and financial results.

Steel companies have significant fixed costs, which are difficult to reduce in response to reduced demand. However, we could implement a variety of measures in response to a market downturn and a decline in demand for steel products. These measures might include: curtailing the purchase of raw materials; spreading raw material contracts over a longer period of time; reducing capital spending; negotiating reduced pricing for major inputs, reducing headcount through temporary layoffs, limiting overtime and reducing use of contractors; managing fixed costs with changes in production levels; improving operational practices to reduce lead time; and venturing into export markets in order to increase capacity utilization. However, these initiatives may not prove sufficient, in terms of cost reduction or in realigning our production levels with reduced demand, to achieve profitability and maintain cash flow necessary to pay for capital expenditures and other funding needs.

Failure to complete, or delays in completing, our EAF Transformation could adversely affect our business and prospects. There are significant risks and uncertainties associated with, and we may fail to realize the anticipated benefits of, the EAF Transformation.

The EAF Transformation may never be completed or may only be completed after significant delays and/or cost overruns. Failure to complete, or delays in completing, the EAF Transformation, could have a material adverse effect on our business, financial position, financial performance or prospects.

In addition, the EAF Transformation will require significant capital expenditures and divert the attention of management from our business. As of March 31, 2024, we have invested approximately C$562.8 million in capital expenditures towards building and preparing the EAF Transformation, which funds will have been wasted should the EAF Transformation not be completed. The EAF Transformation will also require a number of permits, including environmental compliance approvals in respect of sewage works and air/noise, as well as indigenous consultations

- 25 -

and the adoption of site specific standards under the Canadian Environmental Protection Act, 1999 (“CEPA”), none of which are guaranteed to be granted or adopted. In particular, failure to properly consult and consider indigenous nations’ rights in the development of the EAF Transformation may result in legal challenges which may lead to uncertainty, increased project costs, redesigns, mitigation measures, compensation for impacts on indigenous lands, reputational damage and/or delays in obtaining necessary permits and approvals. See “—Indigenous groups’ claims and rights to consultation and accommodation may affect our ability to fully transition the EAF to electrical power” below. If we are not successful at integrating the EAF and related technology and equipment into our business, our cost of production relative to our competitors may increase and we may cease to be profitable or competitive. The EAF Transformation may be more costly than expected to complete and entails additional risks as to whether the EAF and related technology and equipment will reduce our cost of production sufficiently to justify the capital expenditure to obtain them. Additionally, there is no guarantee that the EAF Transformation will allow us to achieve our emissions targets. If such risks were to materialize, the anticipated benefits of the EAF Transformation may not be fully realized, or realized at all.

Construction projects are subject to risks, including delays and cost overruns, which could have an adverse impact on our liquidity and results of operations.

As part of our growth strategy with EAF steelmaking, we must contract for the procurement of technology and construction services. Our construction projects are subject to the risks of delay or cost overruns inherent in any large construction project, including costs or delays resulting from the following:

● unexpected long delivery times for, or shortages of, key equipment, parts and materials;

● shortages of skilled labor and other shipyard personnel necessary to perform the work;

● unforeseen increases in the cost of equipment, labor and raw materials, particularly steel;

● unforeseen design and engineering problems;

● unanticipated actual or purported change orders;

● work stoppages;

● latent damages or deterioration to equipment and machinery in excess of engineering estimates and assumptions;

● failure or delay of third-party service providers and labor disputes;

● disputes with fabricators and other suppliers;

● delays and unexpected costs of incorporating parts and materials needed for the completion of projects;

● financial or other difficulties of suppliers;

● adverse weather conditions; and

● inability to obtain required permits or other approvals.

For example, our Plate Mill Modernization experienced significant delays in our second fiscal quarter of 2022. Additionally, volume through our DSPC was negatively affected by production shortfalls during the second fiscal quarter of 2022, mainly due to temporary workforce availability events. These events contributed to a production shortfall, resulting in a decline in shipments, which had an adverse impact on our business, financial condition and results of operations. If we experience other similar delays and cost overruns in the construction of the EAF furnaces due to certain of the factors listed above, it could also adversely affect our business, financial condition and results of operations.

Our exposure to the higher cost of internally generated power and market pricing for electricity sourced from the current grid in Northern Ontario may have an adverse impact on our production and financial performance if we are able to complete the EAF Transformation.

- 26 -

Electricity is a significant input required in EAF steelmaking, and competitor EAF producers typically enter into fixed-price electricity contracts. Our exposure to the higher cost of internally generated power and market pricing for electricity sourced from the current grid in Northern Ontario may have an adverse impact on our production and financial performance if we are able to complete the EAF Transformation. We have limited access to power from the current grid in Northern Ontario. As a result, we are planning to upgrade our internal natural gas power plant in order to supply sufficient power in combination with the available grid power to operate EAF furnaces. Delays in acquiring the specialized power equipment and associated specialty services may impact our timing to complete the EAF Transformation. Furthermore, operating an internal power plant subjects us to planned and unplanned outages to maintain and/or repair the equipment, which would result in an associated outage of the steelmaking production.

The Ontario provincial regulator, Independent Electricity System Operator (“IESO”), plans for the resources needed to meet Ontario’s future electricity needs. This includes accounting for Ontario’s forecasted electricity requirements, and carrying out integrated resource planning for energy efficiency, generation and transmission infrastructure to meet those requirements. This process is not within our control. We will need to operate our internal natural gas power plant until local and regional power system upgrades are determined and recommended by the IESO and approved by the Ontario Energy Board for installation. In the long-term, in order to operate EAF furnaces from grid power alone, we will require regional power system upgrades, with new transmission wires outside the city providing for more power to Sault Ste. Marie. These regional power system upgrades may not be completed until 2029 or later.

Due to our limited access to power from the current grid in Northern Ontario, our plan is to adapt our number 7 blast furnace (“Blast Furnace No. 7”) to run at a lower rate in order to feed liquid iron into the EAFs to reduce our power requirements and to balance the amount of power expected to be available from internal generation and available grid power. Operating the blast furnace at a reduced rate subjects us to planned and unplanned outages in order to maintain and/or repair the equipment, which would result in associated outages in steelmaking production.

Operating the blast furnace together with EAF steelmaking while using internal power generation from natural gas (“Hybrid Mode”) presents both an operating risk and a market risk, as we would be running the facilities at suboptimal levels and are subject to outages with internal power generation. Furthermore, the presence of ice and/or snow in steel scrap materials as they are introduced to EAF steelmaking could result in explosions which may result in further unplanned outages and/or health and safety consequences.

We are pursuing a local electricity transmission infrastructure upgrade and technical contingency solution to allow us to access more power sooner from the current grid into Sault Ste. Marie. Delays in designing, approving, and installing these local infrastructure upgrades may result in a delay or inability to access more power from the grid. This may result in a disruption to our steelmaking operations and/or failure to grow our business.

Indigenous groups’ claims and rights to consultation and accommodation may affect our ability to fully transition the EAF to electrical power.

Governments in many jurisdictions must consult and enter into consensus seeking with indigenous groups with respect to grants of property rights and the issuance or amendment of project authorizations. These requirements are subject to change from time to time. As examples, certain provinces and the Canadian federal government have introduced legislation to implement the United Nations Declaration on the Rights of Indigenous Peoples, which legislation requires further legislative changes to ensure that other acts are consistent with such Declaration. Our EAF Transformation includes permitting and required upgrades to the electricity transmission infrastructure in Northern Ontario, including in areas where indigenous groups may be affected, and as a result, we will be required to consult and consider such indigenous groups’ rights in connection with the project development. Failure to properly consult and consider indigenous groups’ rights in the development of the electricity transmission infrastructure in Northern Ontario or other similar projects could result in legal challenges which may lead to uncertainty, increased project costs, redesigns, mitigation measures, compensation for impacts on indigenous lands, reputational damage and/or

- 27 -

delays in obtaining necessary permits and approvals. Should such adverse effects occur, we may be unable to transition the EAF to full reliance on electrical power, which could cause the anticipated benefits of the EAF Transformation to not be fully realized, or realized at all.

In connection with the EAF Transformation, our access to an adequate supply of the various grades of steel scrap at competitive prices may result in a disruption to our operations and/or financial performance.

The principal raw material of our transformation to EAF steelmaking operations will be scrap metal derived from internal operations within our steel mills and industrial scrap generated as a by-product of manufacturing; obsolete scrap recovered from end-of-life manufactured goods such as automobiles, appliances, and machinery; and demolition scrap recovered from obsolete structures, containers and machines. Scrap is a global commodity influenced by economic conditions in a number of industrialized and emerging markets throughout Asia, Europe and North America.

The markets for scrap metals are highly competitive, both in the purchase of raw or unprocessed scrap, and processed scrap. As a result, we will need to compete with other steel mills in attempting to secure scrap supply through direct purchasing from scrap suppliers. Any failure to secure access to an adequate supply of the various grades of steel scrap at competitive prices may result in a disruption to our operations and/or financial performance.

We will also need to supplement our EAF operations with higher-purity substitutes for ferrous scrap which may be sourced from higher-quality-lower-residual prime scrap, or iron units such as pig iron, pelletized iron, hot briquetted iron, direct reduced iron, and other forms of processed iron. Any failure to secure access to an adequate supply of the substitutes for ferrous scrap at competitive prices may result in a disruption to our operations and/or financial performance. Furthermore, we may not be able to source competitive modes of freight transportation for inbound scrap and other materials.

As we transition our current product offerings to steel from EAF steelmaking, we require a blend of various grades of scrap and higher-purity substitutes which, depending on product chemistry specifications and requirements may result in an uncompetitive cost relative to our competitors with respect to similar products. In addition, as we transition production to EAF steelmaking, we may not be able to transition all current grades of steel at a competitive metallics cost, thereby resulting in reduced margins.

Many variables can impact ferrous scrap prices, including the level of Canadian steel production, the level of exports of scrap from the United States and Canada, and the amount of obsolete scrap production. Canadian ferrous scrap prices generally have a strong correlation and spread to global pig iron pricing. Generally, as Canadian steel demand increases, so does scrap demand and resulting scrap prices. The reverse is also typically true with scrap prices following steel prices downward when supply exceeds demand, but this is not always the case. When scrap prices greatly accelerate, this can challenge one of the principal elements of an EAF based steel mill’s traditional lower cost structure – the cost of its metallic raw material.

Even if we are able to complete the EAF Transformation, we may fail to achieve the anticipated benefits due to reduced product qualities.

Even if we are to complete the EAF Transformation, we may fail to achieve the anticipated benefits. For example, as a result of residual chemistry attributes of finished steel from the EAF processing of scrap, we may be limited in our ability to competitively produce the range of product types and qualities that we were previously able to produce using our blast furnace. This may result in a less competitive product or a more limited range of products that we are able to competitively produce, either of which could result in reduced sales and have a material adverse effect on our results of operations and/or adversely affect our reputation with existing and potential customers.

The ongoing Russia-Ukraine conflict and the consequent wave of international sanctions against Russia are expected to reduce the supply of steelmaking raw materials and steel products in international markets.

Armed conflict commenced between Russia and Ukraine in February 2022 and has continued through the date of this Annual Information Form. In response, Canada, the United States, the United Kingdom and the European Union, among others, have imposed a wave of sanctions against certain Russian institutions, companies and citizens. As a result of the conflict and related sanctions, energy prices have continually climbed and foreign trade transactions involving Russian and Ukrainian counterparties have been severely affected.

The extent and duration of the conflict, resulting sanctions and resulting future market disruptions are impossible to predict, but could be significant. Our board of directors is monitoring the potential impacts of the conflict in Ukraine, as well as the current conflict in the Middle East, on our business overall and in particular, risks related to cybersecurity, sanctions and market disruptions.

Although we do not have business operations or customers in Russia or Ukraine, sanctions, an increase in cyberattacks and increases in energy costs, among other potential impacts on regional and global economic environment and currencies, may cause demand for our products and services to be volatile, cause abrupt changes in our customers’ buying patterns, interrupt our ability to obtain raw materials from those regions. In addition, in challenging economic times, our current or potential future customers may experience cash flow problems and as a result may modify, delay or cancel plans to purchase our products.

Russia has a significant participation in the international trade of steel slabs, iron ore, pig iron, metallurgical coal and pulverized coal for injection and alloys. In addition, Ukraine has a significant participation in the international trade of pig iron, steel slabs and iron ore. The availability and pricing of these inputs in the international markets are expected to be volatile and could result in limitations to our production levels and higher costs, affecting our profitability and results of operations. As a result of the economic sanctions imposed on Russia, we may be required to purchase raw materials at increased prices.

In addition, there may be an increased risk of cyberattacks by state actors due to the current conflict between Russia and the Ukraine. Any increase in such attacks on us or our systems could adversely affect our operations. Although we maintain cybersecurity policies and procedures to manage risk to our information technology systems, continuously adapt our systems and processes to mitigate such threats, and plan to enhance our protections against such attacks, we may not be able to address these cybersecurity threats proactively or implement adequate preventative measures and we may be unable to promptly detect and address any such disruption or security breach, if at all.

We have a recent history of losses and may not return to or sustain profitability in the future.

Although we were profitable in the fiscal year ended March 31, 2024, we have incurred net losses in recent reporting periods. This history of our business incurring significant losses, among other things, led predecessor operators of our business to seek creditor protection and/or to complete corporate restructuring proceedings. See “Risk Factors - Predecessor operators of our business have sought creditor protection and completed corporate restructurings on a number of occasions.” We may not maintain profitability in future periods, our earnings could decline or grow more slowly than we expect and we may incur significant losses in the future for a number of reasons, including the risks described in this Annual Information Form.

We have aging process infrastructure and other production lines.

As some of our existing infrastructure and production lines age, we face several related risks, including unplanned outages, technological obsolescence of key operating systems, reduced availability of replacement parts, reduced product capability and ultimately lower cost and quality competitiveness in the market. As a result, we may be unable

- 29 -

to maintain profitability in future periods, our earnings could decline or grow more slowly than we expect and we may incur significant losses.

Our cost and operational improvements plan may not continue to be effective.

Our cost and operational improvements strategy has resulted in reduced costs. However, there can be no assurance that we will continue to achieve such savings in the future or that we will realize the estimated future benefits of these plans. Moreover, our continued implementation of these plans may disrupt our operations and performance. Additionally, our estimated cost savings for these plans are based on several assumptions that may prove to be inaccurate and, as a result, there can be no assurance that we will realize these cost savings.

Our utilization rates may decline as a result of increased global steel production and imports.

In addition to economic conditions and prices, the steel industry is affected by other factors such as worldwide production capacity and fluctuations in steel imports/exports and tariffs. Historically, the steel industry has suffered from substantial overcapacity. If demand for steel products was to rapidly decline, it is possible that global production levels will fail to adjust fully. If production increases outstrip demand increases in the market, an extended period of depressed prices and market weakness may result.

China is now the largest worldwide steel producing country by a significant margin and has significant unused capacity. In the future, any significant excess capacity utilization in China and increased exports by Chinese steel companies would depress steel prices in many markets.

We expect that consolidation in the steel sector in recent years should, as a general matter, help producers to maintain more consistent performance through the down cycles by preventing fewer duplicate investments and increasing producers’ utilization and therefore efficiency and economies of scale. However, overcapacity in the industry may re-emerge.

Increased imports of low-priced steel products into North America and decreased trade regulation could impact the North American steel market, resulting in a loss of sales volume and decreased pricing that could adversely impact our operating results and financial position.

Imports of flat-rolled steel to the U.S. accounted for approximately 17% of the U.S. market for flat-rolled steel products in 2023. Imports of flat-rolled steel to Canada accounted for approximately 30% of the Canadian market for flat-rolled steel products in 2023 (Statistics Canada, American Iron and Steel Institute, Phoenix SPI, US Census). Increases in future levels of imported steel to North America could reduce future market prices and demand levels for steel products produced in those markets and reduce our profitability.

In addition, our business has historically been affected by “dumping” – the selling of steel into Canadian or U.S. markets at prices below cost or below the price prevailing in a foreign company’s domestic market. Dumping may result in injury to steel producers in Canada or the U.S. in the form of suppressed prices, lost sales, lower profits and reductions in production, employment levels and the ability to raise capital. Some foreign steel producers are owned, controlled or subsidized by foreign governments. Decisions by these foreign producers to continue production at marginal facilities may be influenced to a greater degree by political and economic policy considerations than by prevailing market conditions and may further contribute to excess global capacity. Although trade legislation to limit dumping has had some success, it may be inadequate to prevent future unfair import pricing practices which individually or collectively could materially adversely affect our business. If Canadian or U.S. trade laws are weakened, an increase in the market share of imports into the U.S. and Canada may occur, which would have a material adverse effect on our business and financial performance.

The Canadian steel industry has worked with the Canadian government to modernize the Canadian trade remedy system to provide the appropriate tools to respond to unfair trade. These principal changes came into force in 2017, 2019 and again in 2022, through a number of amendments to the Special Import Measures Act and related trade remedy regulations to strengthen the trade remedy system, while remaining aligned with international trade rules. In addition, beginning on November 5, 2024, steel importers will be required to report “country of melt and pour” information to the Canada Border Services Agency when completing their customs declarations under Canada’s Steel Import Monitoring Program. The impact that such measures have had, or will have, to remedy unfair trade remains unknown.

Although the Government of Canada continues to work with industry to respond to unfair trade practices, there can be no assurance that such measures will sufficiently offset any resulting loss caused to us by such unfair practices, and there can be no assurance that the protective measures put in place by the Government of Canada and/or the Canadian International Trade Tribunal will be kept in place and, as a result, such unfair trade practices may have a material adverse effect on our business, financial position, results or operations and cash flow.

Tariffs and other trade barriers may restrict our ability to compete internationally.

We have a significant number of customers located in the United States. For the year ended March 31, 2024, 61% of our revenue was from customers located in the United States. Our ability to sell to these customers and compete with producers located in the United States could be negatively affected by tariffs and/or trade restrictions imposed on our products. In addition, we are exposed to the risk that the government support we receive may be perceived as a subsidy by international trade bodies or foreign governments, potentially leading to trade actions or retaliatory measures.

On April 20, 2017, the United States issued an executive order directing the United States Department of Commerce to investigate whether imports of foreign steel are harming U.S. national security. The directive falls under Section 232 of the Trade Expansion Act of 1962, which allows the U.S. president to restrict trade of a good if such trade is determined to be harmful to U.S. national security. On February 16, 2018, the United States Department of Commerce released its report regarding the Section 232 investigation. The recommendations in that report include options regarding tariffs and/or quotas that are intended to adjust the level of steel imports into the United States as it has been determined that those imports are an impairment to national security. Subsequently, the United States announced tariffs of 25% by presidential proclamation dated March 8, 2018 on steel and aluminum imports. Canada, Mexico and certain other countries were granted temporary exemptions, which expired on May 31, 2018. As a result, Canadian steel producers became subject to 25% tariffs on all steel revenues earned on shipments made to the United States effective as of June 1, 2018. Effective on July 1, 2018, Canada began imposing a series of counter tariffs on certain U.S. goods, including steel products. The Canadian government has also announced various relief measures aimed to helping companies affected by the tariffs and counter tariffs on goods imported from the United States.

The United States lifted these tariffs as they relate to Canadian imports effective May 2019, subject to a mutual understanding with Canada on maintaining certain trade levels into the United States. The Canadian government subsequently lifted counter tariffs on goods imported from the United States. As the trade understanding is between countries, there is no assurance that the Canadian domestic steel industry will maintain adherence to the trade level guidelines set out in the understanding. As a result, there can be no assurance that the United States will not once again levy tariffs on our products shipped to customers in the United States.

All of our operations are currently conducted at one facility using one blast furnace and are subject to unexpected equipment failures and other business interruptions.

Our manufacturing processes are dependent upon critical steelmaking equipment such as furnaces, continuous casters, rolling mills and electrical equipment (such as transformers), and this equipment may incur downtime as a result of unanticipated failures. In particular, as a single blast furnace operation, any unplanned or prolonged outage in the operation of the blast furnace and/or steelmaking facility may have a material adverse effect on our ability to produce steel and satisfy pending and new orders, which would materially impact our revenues, cash flows and profitability.

Our predecessor, Old Steelco, experienced plant shutdowns or periods of reduced production as a result of such equipment failures.

On January 21, 2011, Blast Furnace No. 7 experienced significant water leakage and this ultimately led to the chilling of the furnace. Production of raw steel was halted for 23 days with production returning to normal after 33 days.

During fiscal year 2012, a substantial number of stack plate coolers were replaced and a leak detection system was installed at Blast Furnace No. 7. This program has continued into the current fiscal year. The purpose of these measures is to detect and prevent incidents of water into the furnace hearth.

During April 2019, we experienced an unplanned outage that disrupted production in our Blast Furnace No. 7 as a result of an operator error causing a chemistry imbalance of certain materials. The resulting lost production led to a shipping volume reduction during the three-month period ended June 30, 2019, of over 100,000 tons. During April 2019, we recorded a capacity utilization adjustment of C$32.7 million to cost of steel products sold.

On August 7, 2022, we experienced a fire on one of our coal conveyors that supplies coal to two of our three coke production units. No one was injured in this event. While the Company continued to produce coke at a reduced rate, and had sufficient coke inventories, the Company relied on increased purchases of merchant coke.

On January 20, 2024 there was an unexpected structural collapse of a utility corridor supporting various utilities to our coke production plant, which in turn had a cascading adverse effect on various utilities that are essential to our ironmaking operations. The incident necessitated the immediate evacuation of the blast furnace and disrupted the supply of various utilities required for its safe production. No injuries occurred in this event. The repair and restart of the blast furnace, following operational challenges resulting from the collapse lasted approximately three weeks with normal production resuming on February 11, 2024. Minimal production of coke resumed at all three coke oven batteries on January 23, 2024 to maintain asset integrity. When combined with inventories on hand and the availability of third party coke supplies, the Company satisfied its coke requirements for normal steelmaking operations while the repairs to the utility corridor were completed. While significant progress has been made in the reconstruction of the utility corridor and commissioning of the suction main, and efforts have been undertaken to restore some operational functionality to the coke oven batteries; Coke production levels have not stabilized and the batteries are not yet fully operational.

Unexpected interruptions in production capabilities and unexpected failures in our computer systems would adversely affect productivity and financial performance for the affected period. No assurance can be given that a significant shutdown will not occur in the future or that such a shutdown will not have a material adverse effect on our business, financial position or financial performance.

It is also possible that operations may be disrupted due to other unforeseen circumstances such as power outages, explosions, fires, floods, pandemics, states of emergency declared by governmental agencies, environmental incidents, accidents, severe weather conditions and cyberattacks. To the extent that lost production could not be compensated for at

- 32 -

unaffected facilities and depending on the length of the outage, our sales and our unit production costs could be adversely affected.

We could incur significant cash expenses for temporary and potential permanent idling of facilities.

We perform strategic reviews of our business, which may include evaluating each of our plants and operating units to assess their viability and strategic benefits. As part of these reviews, we may idle, whether temporarily or permanently, certain of our existing facilities in order to reduce participation in markets where we determine that our returns are not acceptable. For example, our number 6 blast furnace (“Blast Furnace No. 6”), which could provide redundancy and incremental flexibility to our operating platform, is currently idled. If we decide to permanently idle any facility or assets, we are likely to incur significant cash expenses, including those relating to labor benefit obligations, take-or-pay supply agreements and accelerated environmental remediation costs, as well as substantial non-cash charges for impairment of those assets. If we elect to permanently idle material facilities or assets, it could adversely affect our operations, financial results and cash flows. In the past, certain of our facilities have been idled as a result of poor profitability.

For any temporarily idled facilities, we may not be able to respond in an efficient manner when restarting these to fully realize the benefits from changing market conditions that are favorable to integrated steel producers. When we restart idled facilities, we incur certain costs to replenish raw material inventories, prepare the previously idled facilities for operation, perform the required repair and maintenance activities and prepare employees to return to work safely and resume production responsibilities. The amount of any such costs can be material, depending on a variety of factors, such as the period of time during which the facilities remained idle, necessary repairs and available employees, and is difficult to project.

The North American steel industry and certain industries we serve, such as the automotive, construction, appliance, machinery and equipment, and transportation industries, are cyclical, and prolonged economic declines would have a material adverse effect on our business.

The North American steel industry is cyclical in nature and sensitive to general economic conditions, periods of high inflation and high interest rates. The financial position and financial performance of companies in the steel industry are generally affected by macroeconomic fluctuations in the Canadian, U.S. and global economies. Due mainly to our product mix, we have a higher exposure to spot markets than most of our North American competitors. We are therefore subject to more volatility in selling prices. In addition, steel prices are sensitive to trends in cyclical industries such as the North American automotive, construction, appliance, machinery and equipment, and transportation industries, which are significant markets for our products.

In addition, many of our customers are also affected by economic downturns, high inflation and high interest rates, which may in the future result in defaults in the payment of accounts receivable owing to us and a resulting negative impact on our financial results and cash flows.

There can be no assurance that economic or market conditions will be favorable to the steel industry or any of the end-use industries that we intend to serve in the future. Economic downturns, a stagnant economy or otherwise unfavorable economic or market conditions may adversely affect our business, financial performance and financial position.

The lag between the time an order is placed and when it is fulfilled can have a material impact on our financial results, which could be adverse.

As we have a substantial portion of spot-based sales, orders are priced at current prices, subject to discounts, incentives and other negotiated terms, for production and delivery in the future. Generally, there is a lag of approximately six to eight weeks between when an order is booked and ultimately delivered. At certain times, particularly in rapidly

- 33 -

increasing price environments, lead times could grow even longer based on increased customer demand and orders. As a result, our financial performance generally lags changes in market price, both positive and negative. Furthermore, in the circumstances where market prices are falling, our customers may seek to cancel orders or seek to renegotiate more favorable pricing to reflect the changes in market price. Our financial position and financial performance could be materially adversely affected in such circumstances.

Predecessor operators of our business have sought creditor protection and completed corporate restructurings on a number of occasions.

Old Steelco’s predecessor company initiated a bankruptcy proceeding in 1990 and subsequently emerged from bankruptcy protection by way of a C$60 million bridge loan from the Government of Ontario. As a result of business, operational and financial challenges, Old Steelco’s predecessor company later filed for protection under the CCAA in April 2001 and emerged from creditor protection in 2002 following the completion of a corporate restructuring.

In 2014, as a result of depressed steel prices, a legacy iron ore supply contract that contained above-market pricing terms, substantial pension funding obligations and a significant amount of debt and related interest expense, all of which negatively impacted Old Steelco’s operations, financial position and liquidity, Old Steelco implemented an arrangement under section 192 of the Canada Business Corporations Act (“CBCA”). The CBCA proceedings enabled Old Steelco to restructure its unsecured notes, refinance its secured debt and obtain a significant capital infusion. Old Steelco also commenced a recognition proceeding in the United States under Chapter 15 of the United States Bankruptcy Code, in order to recognize and enforce the arrangement in the United States. On September 15, 2014, the Canadian court issued a final order approving the arrangement, which order was recognized by the U.S. court on September 24, 2014. The arrangement was completed in November 2014.

On November 9, 2015, Old Steelco sought and obtained CCAA protection as a result of, among other things, a dispute with a critical supplier of iron ore, a significant decrease in steel prices, an inability to comply with payment and other obligations under its credit agreements, and operational cost issues. Old Steelco carried out a sale and investment solicitation process that ultimately resulted in Opco’s acquisition of substantially all of the operating assets of Old Steelco on November 30, 2018 in the Restructuring Transaction. The Restructuring Transaction resulted in a significant capital structure deleveraging and negotiated arrangements with a number of labor, pension, and governmental stakeholders. The CCAA proceedings and the Restructuring Transaction were given effect in the United States pursuant to a recognition proceeding under Chapter 15 of the United States Bankruptcy Code.

There can be no assurance that we will not experience serious financial difficulties in the future that would necessitate the commencement of restructuring proceedings, which could have a material adverse effect on our business, financial position, financial performance and prospects and the legal and economic entitlements of our stakeholders.

We are reliant on information technology systems, including cyber security systems, and any failure or breach of such systems could disrupt our operations.

We are reliant on the continuous and uninterrupted operation of our Information Technology (“IT”) systems. User access and security of all sites and corporate IT systems can be critical elements to our operations. Protection against cyber security incidents, cloud security and security of all of our IT systems are critical to our operations. Any IT failure pertaining to availability, access or system security could result in disruption for personnel and could adversely affect our reputation, operations or financial performance.

We may fall victim to successful cyber-attacks and may incur substantial costs and suffer other negative consequences as a result, which may include, but are not limited to, a material disruption in our ability to produce and/or ship steel products, excessive remediation costs that may include liability for stolen assets or information, repairing system damage that may have been caused, and potentially making ransom payments in connection with a cyber-attack. We

- 34 -

and our business partners maintain significant amounts of data electronically in locations on and off our site. This data relates to all aspects of our business, including current and future products, and also contains certain customer, consumer, supplier, partner and employee data. We maintain systems and processes designed to protect this data, including operating in the Cloud and contracting with third-party system security providers, but notwithstanding such protective measures, there is a risk of intrusion, cyber-attacks or tampering that could compromise the integrity and privacy of this data. In addition, we provide confidential and proprietary information to our third-party business partners in certain cases where doing so is necessary to conduct our business. While we obtain assurances from those parties that they have systems and processes in place to protect such data, and where applicable, that they will take steps to assure the protections of such data by third parties, nonetheless those partners may also be subject to data intrusion or otherwise compromise the protection of such data. Any compromise of the confidential data of our customers, consumers, suppliers, partners, employees or ourselves, or failure to prevent or mitigate the loss of or damage to this data through breach of our information technology systems or other means could substantially disrupt our operations, including production delays or downtimes, harm our customers, consumers, employees and other business partners, damage our reputation, violate applicable laws and regulations, subject us to potentially significant costs and liabilities and result in a loss of business that could be material.

Increased global information technology security requirements, vulnerabilities, threats and a rise in sophisticated and targeted cybercrime pose a risk to the security of our systems, our information networks, and to the confidentiality, availability and integrity of our data, as well as to the functionality of our automated and electronically controlled manufacturing operating systems and data collection and analytics capabilities, which our management believes are important and are expected to contribute to our ability to efficiently operate and compete. Although we have adopted procedures and controls, including operating in the Cloud and contracting with third-party system security providers, to protect our information and operating technology, including sensitive proprietary information and confidential and personal data, there can be no assurance that a system or network failure, or security breach, will not occur. This could lead to system interruption, production delays or downtimes and operational disruptions and/or the disclosure, modification or destruction of proprietary and other key information, which could have an adverse effect on our reputation, financial results and financial performance.

Changes to global data privacy laws and cross-border transfer requirements could adversely affect our business and operations.

Our business depends on the transfer of data between our affiliated entities, to and from our business partners, and with third-party service providers, which may be subject to global data privacy laws and cross-border transfer restrictions. While we take steps to comply with these legal requirements, changes to the applicability of those laws may impact our ability to effectively transfer data across borders in support of our business operations.

Changes in accounting standards and subjective assumptions, estimates and judgments by management related to complex accounting matters could significantly affect our financial results or financial position.

IFRS and related accounting pronouncements, implementation guidelines and interpretations with regard to a wide range of matters that are relevant to our business, including but not limited to revenue recognition, inventory, income taxes and litigation, are highly complex and involve many subjective assumptions, estimates and judgments. Changes in these rules or their interpretation or changes in underlying assumptions, estimates or judgments could significantly change our financial performance or financial position in accordance with IFRS.

Our products may not benefit from intellectual property protection and we must respect intellectual property rights of others.

Some information about our products including product chemistries and methods and processes of production are publicly known. Thus, other facilities could produce competitive products using such information. As a result, we

- 35 -

may not be able to distinguish our products from competitors that use the same publicly known chemistries, methods and processes that we use. Other information related to our products including product chemistries and methods and processes used to make them are proprietary to third parties who hold intellectual property rights such as patents or trade secrets therein. Our commercial success depends on our ability to operate without infringing the patents and other proprietary rights of third parties, and there can be no assurance that our operations, product chemistries and methods and processes of production do not or will not infringe the patents or proprietary rights of others. Further, if our competitors use their own proprietary intellectual property rights in their products that we do not have access to, such competitors may have an advantage over us which could have an adverse effect on our business.

Our operations could be materially affected by labor interruptions and difficulties.

We had 2,844 full-time employees as of March 31, 2024, of which approximately 95% are represented by two locals of the United Steelworkers of Canada (“USW”) under two collective bargaining agreements. On August 30, 2022, the Company reported it has been notified by USW Local 2251, the union representing Algoma’s hourly employees that their members have successfully ratified the terms of the new 5-year collective agreement, expiring July 31, 2027. This agreement follows the ratified agreement with the United Steelworkers Local 2724, the union representing its technical, professional, and front-line supervisory employees ratified on July 26, 2022.

Our customers, or companies upon whom we are dependent for raw materials, transportation or other services, could also be affected by labor difficulties. Any such activities, disruptions or difficulties could result in a significant loss of production and sales and could have a material adverse effect on our financial position or financial performance.

Our operations, production levels, sales, financial results and cash flows could be adversely affected by transportation, raw material or energy supply disruptions, or poor quality of raw materials, particularly coal and iron ore.

Due to our location on Lake Superior, we are dependent on seasonally available waterways for the delivery of substantial amounts of raw materials, including coal and iron ore. The waterways close from approximately mid-January to the end of March each year. Extreme cold weather conditions in the United States and Canada impact shipping on the Great Lakes and could disrupt the delivery of iron ore to us and/or increase our costs related to iron ore. Failure to have adequate coal and iron ore on site prior to the closure of the waterways would adversely affect our ability to operate during such closure and could have a material adverse effect on our production levels, business, financial position, financial performance and prospects. For example, during the period from January through April 2014, the upper Great Lakes suffered a severe freeze-over, which resulted in the waterways being generally inaccessible for shipping until early May 2014. As a result, raw material supply was depleted and production was therefore reduced. In addition, extreme weather conditions may limit the availability of railcars or otherwise affect our capacity to receive inbound raw materials, and/or ship products to our customers, which may have a material impact on increasing our costs and /or realizing our revenues. Finally, such disruptions or quality issues, whether the result of severe financial hardships or bankruptcies of suppliers, natural or man-made disasters or other adverse weather events, or other unforeseen circumstances or events, could reduce production or increase costs at our plants and potentially adversely affect customers or markets to which we sell our products. Any resulting financial impact could constrain our ability to fund additional capital investments and maintain adequate levels of liquidity and working capital.

Our business requires substantial capital investment, capital commitments and maintenance expenditures, which we may have difficulty in meeting and will cause us to incur operating costs.

Our operations are capital intensive. We expect to make ongoing capital and maintenance expenditures to achieve and maintain competitive levels of capacity, cost, productivity and product quality. We may not generate sufficient future operating cash flow and external financing sources may not be available in an amount sufficient to enable us to make

- 36 -

anticipated capital expenditures, service or refinance our indebtedness, or fund other liquidity needs. Failure to make sufficient capital investment, capital commitments and maintenance expenditures could have a material adverse effect on our business, financial position, financial performance and prospects.

Our Blast Furnace No. 7 was last relined in 2007 which resulted in a downtime of 52 days and capital expenditure of C$72 million. Relines generally last for 20 years. A common guideline used in the steel industry is to consider a reline when the refractory lining of a blast furnace has worn down to approximately 30% to 40% of its original design thickness. We regularly monitor the health of Blast Furnace No. 7 using non-destructive testing evaluation of the sidewall as assessed by independent experts. On the basis of such reviews, we currently anticipate that Blast Furnace No. 7 would require a future reline no sooner than 2027. The reline, if it occurs, would result in downtime and capital expenditure, which could have a material adverse effect on our business, financial position, financial performance or prospects.

In addition, our profitability and competitiveness are, in large part, dependent upon our ability to maintain low production costs for products with prices that fluctuate based on factors beyond our control. Through our participation in the Canadian Steel Producers Association, we have committed to pursue the aspirational goal of carbon neutrality by 2050. We continue to evaluate strategies to both meet this goal and maintain our competitiveness, including through the modernization of our existing facilities and/or the adoption of other technologies such as less carbon-intensive iron making or EAF steel- making. Unless we continue to invest in newer technologies and equipment such as modernized plants and information technology systems and are successful at integrating such newer technologies and equipment to make our operations more efficient, our cost of production relative to our competitors may increase and we may cease to be profitable or competitive. However, newer technologies and equipment are expensive and the necessary investments may be substantial. Moreover, such investments entail additional risks as to whether the newer technologies and equipment will reduce our cost of production sufficiently to justify the capital expenditures to obtain them. Any failure to make sufficient or appropriate investments in newer technologies and equipment or in integrating such newer technologies and equipment in our operations could have a material adverse effect on our business, financial position, financial performance or prospects.

In addition, the restrictive covenants in the indenture governing our 9.125% Senior Secured Second Lien Notes due April 15, 2029 and other agreements governing our existing and future indebtedness could limit our ability to incur debt to finance sustaining or strategic capital investments, which may limit our ability to maintain or grow the business.

Our ability to generate revenue is dependent on our customer base and certain key customers.

We serve approximately 200 customers across multiple sectors in North America. For the fiscal year ended March 31, 2024, our top ten customers accounted for approximately 51% of our revenue, and sales to one customer represented more than 14% of revenue. The average tenure for our top ten customers is more than 20 years. The composition and concentration of our customer base could change over time.

While we benefit from diverse end market exposure with limited customer concentration, we rely on certain key customers for a material portion of our revenues. These customers may not consistently purchase our products at a particular rate over any subsequent period. The loss of one or more significant customers, or a decline in steel demand for customers operating in particular industries as a result of macroeconomic or industry-specific factors, could have a material adverse effect on our revenues, financial performance and financial position, particularly if we are unable to replace such lost business with new customer orders. In addition, certain of our top customers may be able to exert pricing and other influences on us, requiring us to produce, market, deliver and promote our products in a manner that may be more costly to us.

- 37 -

The closing or relocation of customer facilities could adversely affect us.

Our ability to meet delivery requirements and the overall cost of our products as delivered to customer facilities are important competitive factors. If customers close or move their production facilities further away from our production facility, it could have an adverse effect on our ability to meet competitive conditions, which could result in the loss of sales. Likewise, if customers move their production facilities outside North America, it could result in the loss of potential sales for us.

We depend on third parties to supply sophisticated and complex machinery for our plants and we are exposed to risks relating to the timing or quality of their services, equipment and supplies.

We have purchased in the past, and propose to purchase going forward, equipment, machinery and services from third parties in relation to our plant. Given that we do not have any direct control over these third parties, we rely on them to provide goods and services in a timely manner and in accordance with our specifications. In addition, we require continued and timely support of certain original equipment manufacturers to supply necessary services and parts to maintain our plants at reasonable cost. If we are unable to procure the required services or parts from these manufacturers for any reason (including the closure of operations or bankruptcy of such manufacturers), if the cost of these services or parts exceeds our budget or if the services or parts provided are deficient or sub-standard, there may be an adverse effect on our business, financial position, financial performance, cash flows and prospects.

We depend on third parties for transportation services, and increases in costs or the availability of transportation may adversely affect our business and operations.

Our business depends on the transportation of a large number of products, both domestically and internationally. We rely primarily on third parties (including the Canadian Pacific Railway, Canadian National Railway, McKeil Marine and Purvis Marine) to provide freighter, shipping and rail transportation services, as well as dock capacity, for the products we manufacture as well as delivery of our raw materials. Any increase in the cost of the transportation of our raw materials or products, as a result of increases in fuel or labor costs, higher demand for logistics services, consolidation in the transportation industry or otherwise, may adversely affect our financial performance as we may not be able to pass such cost increases on to our customers.

If any of these providers were to fail to deliver raw materials to us in a timely manner (including due to weather-related problems, strikes, lock-outs or other labor issues, logistical problems or other events), we may be unable to manufacture and deliver our products in response to customer demand in a timely manner or at all. Further, increases in transportation costs, decreased availability of ocean vessels or changes in such costs relative to transportation costs incurred by our competitors, could make our products less competitive, restrict our access to certain markets and have an adverse effect on our production levels, sales, margins and profitability. In addition, if any of these third parties were to cease operations or cease doing business with us, we may be unable to replace them at a reasonable cost.

In addition, such failure or disruption of a third-party transportation provider could harm our reputation, negatively affect our customer relationships and have a material adverse effect on our business, financial position, financial performance and prospects.

Parties with whom we do business may be subject to insolvency risks or may otherwise become unable or unwilling to perform their obligations to us.

We are a party to business relationships, transactions and contracts with various third parties, pursuant to which such third parties have performance, payment and other obligations to us. If any of these third parties were to become subject to insolvency, bankruptcy, receivership or similar proceedings, our rights and benefits in relation to our business relationships, contracts and transactions with such third parties could be terminated, modified in a manner

- 38 -

adverse to us, or otherwise impaired. We cannot make any assurances that we would be able to arrange for alternate or replacement business relationships, transactions or contracts on terms as favorable as our existing business relationships, transactions or contracts if at all. Any inability on our part to do so could have a material adverse effect on our business and financial performance.

A change in our relationship with counterparties to any of our joint ventures may have an adverse effect on that joint venture.

We have entered into and may, in the future, enter into, develop and operate various joint ventures. We believe an important element in the success of any joint venture is a solid relationship between the members of that joint venture. If there is a change in ownership, a change of control, a change in management or management philosophy, a change in business strategy or another event with respect to a member of a joint venture that adversely impacts the relationship between the joint venture members, it could adversely impact that joint venture, which may have a resulting adverse impact on our business and financial performance. In addition, joint ventures necessarily involve special risks. Whether or not we hold a majority interest or maintain operational control in a joint venture, our counterparties may have economic or business interests or goals that are inconsistent with our interests or goals. For example, such parties may exercise veto rights to block actions that we believe to be in our best interests, may take action contrary to our policies or objectives with respect to our investments, or may be unable or unwilling to fulfill their obligations or commitments to the joint venture.

We are dependent on the operation of our port facility to receive raw materials and deliver steel shipments.

In the fiscal year ended March 31, 2024, we received approximately 98% of our raw material inputs and shipped approximately 20% of our total steel shipments and approximately 100% of our by-products through our captive port facility located on-site at our steel plant in Sault Ste. Marie, Canada. Any material or prolonged disruption in our ability to receive or send shipments through the port facility would have a material adverse effect on our business and financial performance.

Any increases in annual funding obligations resulting from our under-funded Pension Plans and Wrap Plan could have a material adverse effect on us.

We are the sponsor of The Algoma Steel Inc. Pension Plan for Hourly Employees (the “Hourly Plan”) and The Algoma Steel Inc. Pension Plan for Salaried Employees (the “Salaried Plan” and, together with the Hourly Plan, the “Pension Plans”), each of which is registered under the Ontario Pension Benefits Act (the “PBA”) which we assumed in connection with the Restructuring Transaction. The most recent actuarial valuations of the Pension Plans are dated April 1, 2023, and indicate that the Pension Plans are underfunded on a solvency basis. The most recent actuarial valuations indicate that the Hourly Plan had a solvency ratio of 84% and that the Salaried Plan had a solvency ratio of 81%. Furthermore, the most recent actuarial valuations indicate that both the Hourly Plan and the Salaried Plan have a going concern funding deficit as at April 1, 2023. The most recent actuarial valuations indicate that the Hourly Plan has a going concern funding ratio of 95% and that the Salaried Plan had a going concern funding ratio of 90%. Although, both plans are fully funded on a going concern basis prior to the prescribed provision for adverse deviations.

In connection with the Restructuring Transaction, Ontario Regulation 484/18: Essar Steel Algoma Inc. Pension Plans for Salaried Employees and Hourly Employees, as filed on November 30, 2018 (the “2018 Pension Regulations”) was implemented to provide a funding framework for the Pension Plans. Under the 2018 Pension Regulations, among other things, the aggregate going concern and solvency special payments to the Pension Plans are capped at C$31 million per annum.

- 39 -

Benefits from the Pension Plans are subject to the Pension Benefits Guarantee Fund (the “PBGF”), which requires us to make annual assessment payments to the PBGF determined based on a formula that includes, among other factors, the funding status and number of members of the pension plan. The 2018 Pension Regulations provide that subsection 57(4) of the PBA does not apply to the Pension Plans and that subsection 57(3) of the PBA does not apply to us in respect of contributions due and not paid into the Pension Plans before the 2018 Pension Regulations came into force. The C$31 million funding cap will cease to apply on the earlier of the year in which we elect to have the funding rules in the General Regulations apply or in 2039.

In addition, we are the sponsor of a closed defined benefit pension plan for pensioners who retired prior to January 1, 2002 (the “Wrap Plan”) that provides a pension benefit in excess of the limits provided by the PBGF. We assumed the Wrap Plan in connection with the completion of the Restructuring Transaction, subject to transitional provisions pending the implementation of regulatory measures. Ontario Regulation 207/19, which was filed on June 20, 2019 (the “Wrap Regulations”), was implemented to provide a funding framework for the Wrap Plan. The Wrap Regulations require us to make monthly contributions to the Wrap Plan equal to the lesser of C$416,667 and the amount of the prior month’s benefit payments from the Wrap Plan fund until the Wrap Plan’s solvency ratio is 100%. This funding requirement supersedes the normal funding requirements under the PBA and the General Regulations. The Wrap Regulations provide that subsection 57(4) of the PBA does not apply to the Wrap Plan and that subsection 57(3) of the PBA does not apply to us in respect of contributions due and not paid into the Wrap Plan before the Wrap Regulations came into force.

While our near-term funding obligations in respect of the Pension Plans and the Wrap Plan are determined in large part based on the 2018 Pension Regulations and the Wrap Regulations, changes to our collective bargaining agreements, the cost of pension benefits paid to plan members, the impact of market outcomes (including interest rates and investment returns), the occurrence of any adverse deviations or changes to governmental regulations affecting the Pension Plans or the Wrap Plan, among other things, could affect the funding status of such pension plans and/or the contributions that we are required to make to the pension plans. We could be adversely impacted by any adverse changes to the funding status of the pension plans or increases in our annual funding obligations.

Post-employment benefits owed to our retirees could increase and obligate us to make greater payments.

We provide certain post-employment benefits to our retirees. These benefits include drug, life insurance and hospitalization coverage. We do not pre-fund these obligations. Our obligations for these benefits could increase in the future due to a number of factors including changes in interest rates, changes to collective bargaining agreements, increasing costs for these benefits, particularly drugs, and any transfer of costs currently borne by the Canadian government to us.

Currency fluctuations, including a significant increase in the value of the Canadian dollar, could have a materially adverse effect on our financial performance and financial position.

For the year ended March 31, 2024, 62% of our revenue was from customers located in the United States. Increases in the value of the Canadian dollar relative to the U.S. dollar make Canadian steel products less competitive in U.S. markets and also encourage steel imports from the United States into Canada. Our revenue is driven by U.S. dollar-based indices. 68% of our cost is based on U.S. dollar-indices and 38% of our cost is in Canadian dollars, which is impacted by exchange rate fluctuation. The increase in the value of the Canadian dollar relative to the U.S. dollar will also have a negative impact on expenditures in Canadian dollars. Therefore, a significant increase in the value of the Canadian dollar could adversely affect our financial performance and financial position.

- 40 -

Limited availability of raw materials and energy may constrain operating levels and reduce profit margins.

We and other steel producers have periodically been faced with problems in obtaining sufficient raw materials and energy in a timely manner due to delays, defaults or force majeure events by suppliers, shortages or transportation problems (such as shortages of barges, vessels, rail cars or trucks, or disruption of rail lines, waterways or natural gas transmission lines), resulting in production curtailments. For example, we faced an increase in the price of natural gas throughout the fourth quarter of our 2014 fiscal year, due to disruptions in supply as a result of extreme weather conditions, including the bursting of the pipeline that supplies the region in which we are located. We may be exposed to additional risks concerning pricing and availability of raw materials from third parties. Any curtailments and escalated costs may further reduce profit margins. Specifically, if demand is such that our blast furnaces are at full production capacity, we may become dependent upon outside purchased coke, especially if some of our existing coke facilities produce at less than capacity.

Environmental compliance and site remediation obligations could result in substantially increased costs and could materially adversely affect our competitive position.

Steel producers such as the Company are subject to numerous environmental laws and regulations, including federal and provincial, relating to the protection of the environment. We are required to comply with an evolving body of Canadian federal, provincial and local environmental, health and safety laws concerned with, among other things, GHG emissions, other emissions into the air, discharges to surface and ground water, the investigation and remediation of contaminated property, noise control, waste management and disposal, mine closure and rehabilitation, and the generation, handling, storage, transportation, discharge, presence and disposal of, or exposure to pollutants, contaminants and hazardous substances. Specifically, the Company can incur regulatory liability as well civil liability for breaches or violations of environmental law, including contamination on-site (soil, groundwater, indoor air), contaminant migration and impacts off-site including in respect of groundwater, rivers, lakes, other waterways, and air emissions. Significant expenditures could be required for compliance with any laws or regulations relating to environmental protection and remediation, which may have an adverse effect on our financial performance and financial position.

We are subject to current and new environmental compliance measures pertaining to the integrated blast furnace coke oven steelmaking operations, including coke oven gas desulfurization and slag granulation, among others. In the event we do not receive exemptions or other accommodations from the relevant regulatory authorities, we may need to invest significant capital in these compliance measures while they remain in operation.

By January 1, 2026, there is a Canadian federal requirement to implement plans and measures to reduce the amount of sulphur dioxide emitted from the combustion of coke oven gas by-product by implementing coke oven gas desulphurization technology. This requirement arises under a notice (the “Notice”) issued under subsection 56(1) of CEPA which requires prescribed persons to prepare and implement pollution prevention plans in respect of specified toxic substances released from the iron and steel sector. The Notice applies to all steel mills, including ours. Facilities subject to the Notice are required, among other things, to prepare a pollution prevention plan that will achieve prescribed baseline emission targets by the specified date, and submit certain written declarations and progress reports. We will be taking an alternative approach to reduce SO2 through its transition to EAF steelmaking, which will see the elimination of cokemaking from our operations. We have provided a pollution prevention plan that reflects this alternative approach to reduce SO2 which has been deemed an acceptable approach to comply with CEPA. Similarly, in order to align with new provincial legislation related to SO2, we have applied for a site-specific standard that includes an action plan to reduce SO2 that reflects the progressive facility shutdown.

- 41 -

In the United States and Canada, certain environmental laws and regulations impose joint and several liabilities on certain classes of persons for the costs of investigation, management and remediation of contaminated properties and for the management of emissions into the environment. Liability may attach regardless of fault or the legality of the release or disposal of the substance or waste at the time it occurred. Some of our present and former facilities have been in operation for many years and, over such time, have used substances and disposed of wastes that may require management, investigation, mitigation and remediation. We could be liable for the costs of such investigations and remediation. Costs for any investigation, management, mitigation and remediation of contamination, on or off site, whether known or not yet discovered, or to address other issues relating to pollution and waste disposal, emissions into the air or water, or the storage or handling of materials, could be substantial and could have an adverse effect on our financial performance. In addition, while we are subject to GHG emissions tax liability in Canada, we need to compete alongside foreign competitors in Canada and the United States that may not be similarly subject to such carbon tax liabilities, resulting in our reduced competitiveness in the market which may affect revenues and profitability.

In connection with the EAF Transformation, we may incur higher carbon tax liabilities in connection with operations in the Hybrid Mode. Algoma has received comfort letters from MECP committing to work together on a pathway to address the support sought in respect of emissions performance units and to mitigate the impact of carbon tax liabilities. Furthermore, the dust generated during the EAF steel scrap melting process may contain a significant amount of zinc, and is considered a hazardous waste, the disposal of which is expensive and regulated.

Our Environmental Department regularly reviews and audits our operating practices to monitor compliance with our environmental policies and legal requirements. Our environmental management system is ISO 14001-2015 registered.

No assurance can be given that unforeseen changes, such as new laws or stricter enforcement policies, including in respect of carbon pricing, the use of compliance payments, or an incident at one of our properties or operations, will not have a material adverse effect on our business, estimated capital or operating costs, financial position, or financial performance. Our operations are required to have governmental permits and approvals. Any of these permits or approvals may be subject to denial, revocation, expiry or modification under various circumstances. Failure to obtain or comply with the conditions and terms of permits or approvals may adversely affect our operations and may subject us to regulatory orders, penalties and fines. In addition, if environmental laws are amended or are interpreted or enforced differently, or if new environmental legislation is enacted, we may be required to obtain additional permits or approvals and incur additional costs. There can be no assurance that we will be able to meet all applicable regulatory requirements. In addition, we may be subject to regulatory orders, penalties, fines or other liabilities arising from our actions imposed under environmental laws, including as a result of actions or other proceedings commenced by third parties, such as neighbors or government regulators, including with respect to an emissions incident at the BP.

On October 18, 2019, there was a rupture of a steam drain line which was located below an electrical room in the BP, which resulted in a loss of power to the BP. In accordance with our emergency procedures, the coke oven gas bleeders were lit to flare the coke oven gas. Additionally, the loss of power caused the cokemaking south raw liquor tank and the tar running tanks to overflow. Raw liquor was conveyed to the MWFP via a sewer located in the BP. This resulted in effluent exceedances at the MWFP for phenol, ammonia and total cyanide and a toxicity failure for rainbow trout.

On June 9, 2022, 460 gear oil was released from Algoma’s MWFP to the St. Mary’s River as a result of a spill that occurred during the night shift in the Plate & Strip Mill. The MECP and the ECCC have initiated a joint investigation against the Company, which is ongoing. In addition, in connection with the January 20, 2024 structural collapse, a quantity of effluent (primarily raw cooling liquor) left our site and entered the adjacent waterway. We believe that the water-related environmental release was fully contained by the evening of January 20, with most of the effluent being contained on-site. As a result, we currently believe that there is a low risk of impact to the adjacent waterway. We

- 42 -

remain in contact with regulatory authorities, including the MECP and ECCC, which are reviewing the incident. To date, we have not received any orders or notices of offense pursuant to environmental laws in Canada or the United States, but may in the future be subject to orders, offenses, penalties, fines or other negative consequences as a result of this incident, which may have an adverse effect on our business, financial condition or results of operations. The economic impact of this incident remains unknown. We are still assessing the impact of this incident, but such incident may subject us to the liabilities described above. In connection with this incident and similar incidents that may occur from time to time, we may need to make significant capital and operating expenditures to detect, repair and/or control discharges or to perform certain corrective actions to meet the conditions of the permits issued pursuant to applicable environmental laws.

Increased regulation associated with climate change and greenhouse gas emissions could impose significant additional costs on our operations.

The effects of government policy, legislation or regulation enacted to address climate change may adversely impact our operations as well as those of our suppliers and our customers, including the transportation of the associated raw materials and products. In addition, government action to address climate change may, among other things, reduce the demand for our products. Although we have made efforts to mitigate the effects of government action related to climate change on our business, there can be no assurance that these efforts will be effective or that the effects of climate change policies will not adversely impact our operations, business and financial results.

Our industry and company could be subject to increased regulatory oversight or changes in government policies that could have adverse effects.

Our industry could be subject to increased regulatory oversight. Changing regulatory policies and other actions by governments and third parties may all have the effect of limiting our revenues and increasing our operating costs, which could have a material adverse effect on our business, financial position and financial performance. Due to regulatory restructuring initiatives at the federal, provincial and state levels, the steel industry has undergone changes over the past several years. Future government initiatives will further change the steel industry. Some of these initiatives may delay or reverse the movement towards competitive markets. We cannot predict the ultimate effect that on-going regulatory changes will have on our business prospects, financial position and financial performance.

Canada’s new Forced and Child Labour in Supply Chains Act requires covered Canadian entities, including Algoma, to release board-approved reports detailing their efforts to prevent and mitigate forced labor and child labor in their supply chains. It also includes new penalties for companies and officers that fail to make these reports or in the event that the reports include misleading statements. Accordingly, we will need to allocate additional resources to supply chain due diligence, as well as to assemble supporting records to prepare accurate reports and minimize supply chain risks.

Impairment in the carrying value of long-lived assets could negatively affect our operating results and reduce our earnings.

We have a significant amount of long-lived assets on our consolidated balance sheets. Under IFRS, we periodically evaluate long-lived assets for potential impairment whenever events or changes in circumstances have occurred that indicate that impairment may exist, or the carrying amount of the long-lived asset may not be recoverable. An impairment loss is recognized if the carrying amount of a long-lived asset is not recoverable based on its estimated future discounted cash flows. Events and conditions that could result in impairment in the value of our long-lived assets include cash flow or operating losses, other negative events or long-term outlook, cost factors that have negative effect on earnings and cash flows, changes in business conditions or strategy, as well as significantly deteriorating industry, market, and general economic conditions. Impairment in the carrying value of long- lived assets could negatively affect our operating results and reduce our earnings.

- 43 -

We face increased competition from alternative materials, which could impact the price of steel and adversely affect our profitability and cash flow.

As a result of increasingly stringent regulatory requirements, designers, engineers and industrial manufacturers, especially those in the automotive industry, are increasing their use of lighter weight and alternative materials, such as aluminum, composites, plastics and carbon fiber in their products. Increased government incentives and requirements for the use of such materials to meet regulatory requirements could reduce the demand for steel products, which could potentially reduce our profitability and cash flows.

Pending or threatened litigation or claims could negatively affect our profitability and cash flow in a particular period.

We are subject to litigation arising in the normal course of business and may be involved in legal disputes or matters with other parties, including governments and their agencies, regulators and members of our workforce, which may result in litigation. The causes of potential litigation cannot be known and may arise from, among other things, business activities, employment matters, including compensation issues, or grievances under our collective bargaining agreements, environmental, health and safety laws and regulations, tax matters and securities matters. The timing of resolutions to such matters, should they arise, is uncertain and we may incur expenses in defending them and the possible outcomes or resolutions could include adverse judgments, orders or settlements or require us to implement corrective measures any of which could require substantial payments and adversely affect our reputation and operations, and may also negatively affect our profitability and cash flow in a particular period.

Failure to maintain our current senior management or inability to attract additional senior management could have an adverse effect on our operations.

Our operations and prospects depend, in large part, on the performance of our senior management team. We cannot assure that such individuals will remain as employees. In addition, we can make no assurance that we would be able to find qualified replacements for any of these individuals if their services were no longer available. The loss of the services of one or more members of senior management or difficulty in attracting, retaining and maintaining additional senior management personnel could have a material adverse effect on our business, financial position and financial performance.

A failure to maintain adequate insurance could have a materially adverse effect on our operations.

To date, we have been able to obtain insurance for the operation of our business. However, there can be no assurance that our existing insurance will be adequate, or that it will be able to be maintained, or that all possible claims that may be asserted against us will be covered by insurance. The occurrence of a significant adverse event that causes losses in excess of limits specified under the relevant policy or losses arising from events not covered by insurance policies, could materially adversely affect our business, financial position, financial performance and prospects.

Our income tax filing positions may be subject to challenge by tax authorities, which could subject us to increased tax liabilities.

We file tax returns that may contain interpretations of tax law and estimates. Positions taken and estimates utilized by us may be challenged by applicable tax authorities. Rulings that alter filed tax returns may have an adverse impact on income. In addition, we are involved in and potentially subject to regular audits from Canadian federal and provincial tax authorities relating to income, capital and commodity taxes and, as a result of these audits, may receive assessments and reassessments.

The Canada Revenue Agency (the “CRA”) has completed its audit of the Goods and Services Tax/Harmonized Sales Tax (GST/HST) for the calendar years ending 2018, 2019 and 2020. In June 2024, the CRA issued notices of reassessment for which the Company has been assessed owing C$1.8 million. The Company has accrued C$1.3 million pertaining to this audit at March 31, 2024. In addition, the CRA is currently auditing the Company’s income tax return for the calendar year ended 2021 and the Company has not received further correspondence at this time pertaining to their audit.

We are subject to risks related to shifting steel supplies.

As traditional steel-consuming markets are negatively impacted from reduced demand due to a variety of factors, high inflation and interest rates, or other regulatory changes (such as, for instance, the revocation in January 2021 of the presidential permit necessary to construct and operate the Keystone oil pipeline at the international border of Canada and the United States), suppliers of steel products into these affected sectors will divert their sales efforts to markets where we traditionally participate, thereby creating pressure on lowering pricing in response to increased supply. The oil and gas industry is a significant end market for steel, and has experienced and continues to experience a significant amount of disruption and oversupply at a time of declining demand, resulting in more competition in other sectors of the economy.

Changes in our credit profile may affect our relationships with our suppliers, which could have a material adverse effect on our liquidity.

Changes in our credit profile may affect the way our suppliers view our ability to make payments and may induce them to shorten the payment terms of their invoices or require us to prepay, particularly given our high level of outstanding indebtedness. Given the large dollar amounts and volume of our purchases from suppliers, a change in payment terms may have a material adverse effect on our liquidity and our ability to make payments to our suppliers, and consequently may have a material adverse effect on our business, financial performance and financial position.

Some of our operations present significant risk of injury or death.

The industrial activities conducted at certain of our facilities present significant risk of serious injury or death to our employees, contractors, customers or other visitors to our operations. For example, on February 7, 2024, there was an incident at the north casthouse of the blast furnace complex where we believe slag made contact with moisture in the hot iron trough, resulting in injury to twelve workers, with five needing treatment in hospital. In addition, in June 2023 a fatal incident took place involving the employee of a contractor, retained to perform specialized maintenance work cleaning an out-of-service gas line. These incidents remain under investigation, and to date the Company has not received any charges or violations of regulations. Notwithstanding our safety precautions, including our material compliance with federal and provincial employee health and safety regulations, we may be unable to avoid material liabilities for injuries or deaths. We maintain workers’ compensation insurance to address the risk of incurring material liabilities for injuries or deaths, but there can be no assurance that the insurance coverage will be adequate or will continue to be available on the terms acceptable to us, or at all, which could result in material liabilities to us for any injuries or deaths. We could also incur fines and other sanctions as a result of safety incidents.

Our cross-border operations require us to comply with anti-corruption laws and regulations of the U.S. government and various non-U.S. jurisdictions.

Doing business in multiple countries requires us and our subsidiaries to comply with Canadian and other laws and regulations governing corruption and bribery, including the Canadian Corruption of Foreign Public Officials Act. The laws generally prohibit companies and their officers, directors, employees and agents acting on their behalf from corruptly offering, promising, authorizing or providing anything of value to foreign officials for the purposes of influencing official decisions or obtaining or retaining business or otherwise obtaining favorable treatment. As a result, business dealings between our employees or our agents and any such public official could expose us to the risk of

- 45 -

violating anti-corruption laws. Violations of these legal requirements are punishable by criminal fines and imprisonment, civil penalties, disgorgement of profits, injunctions, debarment from government contracts as well as other remedial measures. We have established policies and procedures designed to assist us and our personnel in complying with applicable laws and regulations; however, we cannot assure investors that these policies and procedures will completely eliminate the risk of a violation of these legal requirements. Any such violation (inadvertent or otherwise) could have a material adverse effect on our business prospects, financial position and financial performance.

Shortages of skilled labor, increased labor costs, or our failure to attract and retain other highly qualified personnel in the future could disrupt our operations and adversely affect our financial results.

We depend on skilled labor for the manufacture of our products. Our continued success depends on the active participation of our key employees. Shortages of some types of skilled labor could restrict our ability to maintain or increase production rates, lead to production inefficiencies and increase our labor costs. The competitive nature of the labor markets in which we operate, the cyclical nature of the steel industry and the resulting employment needs increase our risk of not being able to recruit, train and retain the employees we require at efficient costs and on reasonable terms, particularly when the economy expands, production rates are high or competition for such skilled labor increases. Many companies, including ours, have had employee lay-offs as a result of reduced business activities in an industry downturn. The loss of our key people or our inability to attract new key employees could adversely affect our operations. Additionally, layoffs or other adverse actions could result in an adverse relationship with our workforce. If we are unable to recruit, train and retain adequate numbers of qualified employees on a timely basis or at a reasonable cost or on reasonable terms, our business and financial performance could be adversely affected.

The expansion of social media platforms present new risks and challenges.

The expansion of social media platforms presents new risks and challenges. The inappropriate use of certain social media vehicles could cause brand damage or information leakage or could lead to legal implications from the improper collection and/or dissemination of personally identifiable information or the improper dissemination of material information. In addition, negative posts or comments about us and/or any of our key personnel on any social networking web site could seriously damage our reputation. If our sensitive information is disclosed or if our reputation or that of our key personnel is seriously damaged through social media, it could have a material adverse effect on our business, financial position and financial performance.

If we are unable for any reason to meet the continued listing requirements of Nasdaq or the TSX, such action or inaction could result in a delisting of the Common Shares or Warrants.

If we fail to satisfy the continued listing requirements of Nasdaq or the TSX (for example, the Nasdaq corporate governance requirements or the Nasdaq minimum closing bid price requirement), such exchanges may take steps to delist the Common Shares or Warrants. Such a delisting would likely have a negative effect on the price of the Common Shares or Warrants and would impair your ability to sell or purchase the Common Shares or Warrants when you wish to do so. In the event of a delisting, we can provide no assurance that any action taken by us to restore compliance with listing requirements would allow the Common Shares or Warrants to become listed again, stabilize the market price or improve the liquidity of the Common Shares or Warrants, prevent such securities from dropping below any minimum bid price requirement or prevent future non-compliance with Nasdaq’s or the TSX’s listing requirements.

- 46 -

If securities and industry analysts do not publish research or reports about our business or publish negative reports about our business, our share price and trading volume may suffer.

The trading market for the Common Shares is and will be influenced by the research and reports that securities or industry analysts publish about us or our business. We do not have control over such analysts and cannot provide any assurance that analysts will continue to cover Algoma or provide favorable coverage. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts cease coverage of Algoma or fail to regularly publish reports on Algoma, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

There is a risk that we will fail to maintain an effective system of internal controls and our ability to produce timely and accurate financial statements or comply with applicable regulations could be adversely affected. We may identify material weaknesses in our internal controls over financing reporting which we may not be able to remedy in a timely manner.

As a public company, we operate in an increasingly demanding regulatory environment, which requires us to comply with the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), the regulations of Nasdaq and the TSX, the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) and Canadian securities regulators, expanded disclosure requirements, accelerated reporting requirements and more complex accounting rules. Company responsibilities required by the Sarbanes-Oxley Act include establishing corporate oversight and adequate internal control over financial reporting and disclosure controls and procedures. Effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent financial fraud. Prior to becoming a public company in October 2021, we had never been required to test our internal controls within a specified period and, as a result, we may experience difficulty in meeting these reporting requirements in a timely manner.

The process of maintaining our accounting and financial functions and infrastructure requires significant professional fees, internal costs and management efforts. Any disruptions or difficulties in using our internal systems could adversely affect our controls and harm our business. Moreover, such disruption or difficulties could result in unanticipated costs and diversion of management’s attention. In addition, we may discover additional weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Our internal control over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we are unable to maintain proper and effective internal controls, we may not be able to produce timely and accurate financial statements. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed, investors could lose confidence in our reported financial information and we could be subject to sanctions or investigations by Nasdaq, the TSX, the SEC, Canadian securities regulators or other regulatory authorities.

We have incurred and expect to continue to incur increased costs as a result of our operation as a public company, and our management is and will continue to be required to devote substantial time and resources to employing new compliance initiatives in order to comport with the regulatory requirements applicable to public companies.

We have incurred and expect to continue to incur significant legal, accounting and other expenses as a public company that we did not incur as a private company. As a public company, we are subject to the reporting requirements of the

- 47 -

United States Securities Exchange Act of 1934 (the “Exchange Act”), the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules adopted, and to be adopted, by the SEC, Canadian securities regulators, Nasdaq and the TSX. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have substantially increased our legal and financial compliance costs and to have made some activities more time-consuming and costly. For example, these rules and regulations have and are expected to continue to make it more difficult and more expensive for us to obtain director and officer liability insurance and we have or may be forced to accept reduced policy limits or incur substantially higher costs to maintain the same or similar coverage. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers. We are continuously evaluating and monitoring developments with respect to these rules and regulations, and we cannot predict or estimate the amount or timing of additional costs we may incur to respond to any new requirements we may be subject to in the future.

Our Investor Rights Agreement provides certain IRA Parties the right to nominate up to four of our directors.

In connection with the consummation of our merger (the “Merger”) with Legato Merger Corp. (“Legato”), we entered into an Investor Rights Agreement pursuant to which, among other things, certain parties to the Investor Rights Agreement (“IRA Parties”) that previously had board designation rights with respect to Algoma Steel Holdings Inc. have the right to nominate, in the aggregate, four directors to our board for so long as they beneficially own at least 7.36% of our outstanding Common Shares. As of the date of this Annual Information Form, none of the IRA Parties meet the requisite ownership threshold required to nominate a director for election to our board, and, in addition, the we have been advised that one of the IRA Parties, Barclays Bank PLC, has permanently surrendered its nomination rights under the Investor Rights Agreement. If such IRA Parties are able to exert significant influence over the board as a result of their nomination rights pursuant to the Investor Rights Agreement, other holders of Common Shares may have limited ability to influence corporate matters and, as a result, we may take action that other holders of Common Shares do not view as beneficial.

We are a foreign private issuer and, as a result, are not subject to U.S. proxy rules and are subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. domestic public company.

We report under the Exchange Act as a non-U.S. company with foreign private issuer status. Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including (1) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act, (2) the sections of the Exchange Act requiring insiders to file public reports of their share ownership and trading activities and liability for insiders who profit from trades made in a short period of time and (3) the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q containing unaudited financial and other specified information, although we are subject to Canadian laws and regulations with regard to certain of these matters and intend to furnish comparable quarterly information on Form 6-K. In addition, foreign private issuers are not required to file their annual report on Form 40-F until 90 days (the due date of an annual information form for Canadian foreign private issuers utilizing the multijurisdictional disclosure system, or MJDS) after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year and U.S. domestic issuers that are large accelerated filers are required to file their annual report on Form 10-K within 60 days after the end of each fiscal year. Foreign private issuers are also exempt from Regulation FD, which is intended to prevent issuers from making selective disclosures of material information. As a result of all of the above, you may not have the same protections afforded to shareholders of a company that is not a foreign private issuer.

- 48 -

As we are a “foreign private issuer” and follow certain home country corporate governance practices, our shareholders may not have the same protections afforded to shareholders of companies that are subject to all Nasdaq corporate governance requirements.

As a foreign private issuer, we have the option to follow certain home country corporate governance practices rather than those of Nasdaq, provided that we disclose the requirements we are not following and describe the home country practices we are following. We rely on this “foreign private issuer exemption” with respect to the Nasdaq rules for shareholder meeting quorums and Nasdaq rules requiring shareholder approval. We may in the future elect to follow home country practices with regard to other matters. As a result, our shareholders do not have the same protections afforded to shareholders of companies that are subject to all Nasdaq corporate governance requirements.

Algoma may lose its foreign private issuer status in the future, which could result in significant additional costs and expenses.

As discussed above, Algoma is a foreign private issuer, and therefore is not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act and may take advantage of certain exemptions to Nasdaq’s corporate governance rules. The determination of foreign private issuer status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter, and, accordingly, the next determination will be made with respect to Algoma on September 30, 2024. In the future, Algoma would lose its foreign private issuer status if (1) more than 50% of its outstanding voting securities are owned by U.S. residents and (2) a majority of its directors or executive officers are U.S. citizens or residents, or it fails to meet additional requirements necessary to avoid loss of foreign private issuer status. If Algoma loses its foreign private issuer status, it will be required to file with the SEC periodic reports and registration statements on U.S. domestic issuer forms, which are more detailed and extensive than the forms available to a foreign private issuer. Algoma would also have to mandatorily comply with U.S. federal proxy requirements, and its officers, directors and principal shareholders will become subject to the short-swing profit disclosure and recovery provisions of Section 16 of the Exchange Act. In addition, it would lose its ability to rely upon exemptions from certain corporate governance requirements under the listing rules of Nasdaq. As a U.S. listed public company that is not a foreign private issuer, Algoma would incur significant additional legal, accounting and other expenses that it will not incur as a foreign private issuer.

We may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition and results of operations.

For a variety of potential factors, which are currently unforeseen, we may be forced to write-down or write-off assets, restructure its operations, or incur impairment or other charges that could result in us reporting losses. Even though these charges may be non-cash items and would not have an immediate impact on Algoma’s liquidity, the fact that Algoma would report charges of this nature could contribute to negative market perceptions of Algoma or its securities. In addition, charges of this nature may cause Algoma to violate net worth or other covenants to which Algoma may be subject as a result of Algoma obtaining debt financing. Accordingly, securityholders could suffer a reduction in the value of their Common shares and Warrants and such securityholders are unlikely to have a remedy for such reduction in value.

The grant and future exercise of registration rights may adversely affect the market price of Common Shares.

The Investor Rights Agreement provides that we will, under certain circumstances, agree to file a registration statement as soon as practicable upon a request from certain IRA Parties to register the resale of certain registrable securities under the United States Securities Act of 1933 (the “U.S. Securities Act”) and applicable Canadian securities laws (such request, a “demand registration”). Algoma has also agreed to provide customary “piggyback” registration rights with respect to any valid demand registration request. We have, and intend to continue to maintain, a registration statement in respect of certain registrable securities under the Investor Rights Agreement.

- 49 -

The registration of these securities permits the public sale of such securities. The registration and availability of such a significant number of securities for trading in the public market may have an adverse effect on the market price of Common Shares. See “Risk Factors - A significant portion of our total outstanding Common Shares may be sold into the market at any time. This could cause the market price of Common Shares and Warrants to drop significantly, even if our business is doing well.”

The IRS may not agree that Algoma should be treated as a non-U.S. corporation for U.S. federal income tax purposes.

Although Algoma is incorporated and tax resident in Canada, the U.S. Internal Revenue Service (the “IRS”) may assert that it should be treated as a U.S. corporation for U.S. federal income tax purposes pursuant to Section 7874 of the Internal Revenue Code of 1986 (the “Code”). For U.S. federal income tax purposes, a corporation is generally considered a U.S. “domestic” corporation if it is created or organized in or under the laws of the U.S., any state thereof, or the District of Columbia. Because Algoma is not so created or organized (but is instead incorporated only in Canada), it would generally be classified as a foreign corporation (that is, a corporation other than a U.S. “domestic” corporation) under these rules. Section 7874 of the Code provides an exception under which a corporation created or organized only under foreign law may, in certain circumstances, be treated as a U.S. corporation for U.S. federal income tax purposes.

Based on the terms of the Merger, the rules for determining share ownership under Section 7874 of the Code and the Treasury regulations promulgated thereunder (the “Section 7874 Regulations”), and certain factual assumptions, Algoma does not expect to be treated as a U.S. corporation for U.S. federal income tax purposes under Section 7874 of the Code as a result of the Merger. However, the application of Section 7874 of the Code is complex, is subject to detailed regulations (the application of which is uncertain in various respects and would be impacted by changes in such U.S. tax laws and regulations with possible retroactive effect) and is subject to certain factual uncertainties. Furthermore, Algoma has not sought and will not seek any rulings from the IRS as to such treatment, and the closing of the Merger was not conditioned upon achieving, or receiving a ruling from any tax authority or opinion from any tax advisor with regard to, any particular tax treatment. Accordingly, there can be no assurance that the IRS will not challenge the status of Algoma as a foreign corporation under Section 7874 of the Code or that such challenge would not be sustained by a court.

If the IRS were to successfully challenge under Section 7874 of the Code Algoma’s status as a foreign corporation for U.S. federal income tax purposes, Algoma and certain Algoma shareholders could be subject to significant adverse tax consequences, including a higher effective corporate income tax rate on Algoma and future withholding taxes on certain Algoma shareholders, depending on the application of any income tax treaty that might apply to reduce such withholding taxes. In particular, holders of Common Shares and/or Warrants would be treated as holders of stock and warrants of a U.S. corporation.

Investors should consult their own advisors regarding the application of Section 7874 of the Code to Algoma.

Section 7874 of the Code may limit the ability to use certain tax attributes since the Merger, increasing Algoma’s U.S. affiliates’ U.S. taxable income or having other adverse consequences to Algoma and Algoma’s shareholders.

Following the acquisition of a U.S. corporation by a foreign corporation, Section 7874 of the Code can limit the ability of the acquired U.S. corporation and its U.S. affiliates to use U.S. tax attributes (including net operating losses and certain tax credits) to offset U.S. taxable income resulting from certain transactions, as well as result in certain other adverse tax consequences, even if the acquiring foreign corporation is respected as a foreign corporation for purposes of Section 7874 of the Code. In general, if a foreign corporation acquires, directly or indirectly, substantially all of the properties held directly or indirectly by a U.S. corporation, and after the acquisition the former shareholders of the acquired U.S. corporation hold at least 60% (by either vote or value) but less than 80% (by vote and value) of the

- 50 -

shares of the foreign acquiring corporation by reason of holding shares in the acquired U.S. corporation, subject to other requirements, certain adverse tax consequences under Section 7874 of the Code may apply.

If these rules apply to the Merger, Algoma and certain of Algoma’s shareholders may be subject to adverse tax consequences including, but not limited to, restrictions on the use of tax attributes with respect to “inversion gain” recognized over a 10-year period following the transaction, disqualification of dividends paid from preferential “qualified dividend income” rates and the requirement that any U.S. corporation owned by Algoma include as “base erosion payments” that may be subject to a minimum U.S. federal income tax any amounts treated as reductions in gross income paid to certain related foreign persons. Furthermore, certain “disqualified individuals” (including officers and directors of a U.S. corporation) may be subject to an excise tax on certain stock-based compensation held thereby at a rate of 20%.

Based on the terms of the Merger, the rules for determining share ownership under Section 7874 of the Code and the Section 7874 Regulations (as defined above), and certain factual assumptions, Algoma does not expect to be subject to these rules under Section 7874 of the Code as a result of the Merger. The above determination, however, is subject to detailed regulations (the application of which is uncertain in various respects and would be impacted by future changes in such U.S. tax laws and regulations, with possible retroactive effect) and is subject to certain factual uncertainties. Furthermore, Algoma has not sought and will not seek any rulings from the IRS as to such treatment, and the closing of the Merger was not conditioned upon achieving, or receiving a ruling from any tax authority or opinion from any tax advisor with regard to, any particular tax treatment. Accordingly, there can be no assurance that the IRS will not challenge whether Algoma is subject to the above rules or that such a challenge would not be sustained by a court.

However, even if Algoma is not subject to the above adverse consequences under Section 7874 of the Code, Algoma may be limited in using its equity to engage in future acquisitions of U.S. corporations over the 36-month period following the Merger. If Algoma were to be treated as acquiring substantially all of the assets of a U.S. corporation within the 36-month period after the Merger, certain rules under the Section 7874 Regulations would make it more likely that Section 7874 of the Code will apply to such subsequent acquisition.

Investors in Algoma should consult their own advisors regarding the application of Section 7874 of the Code to Algoma.

Risks Related to Ownership of Common Shares and Warrants

We may issue additional Common Shares or other securities without shareholder approval, which would dilute existing ownership interests and may depress the market price of Common Shares.

We may issue additional Common Shares or other equity securities of equal or senior rank in the future in connection with, among other things, our equity incentive plan, without shareholder approval, in a number of circumstances. Our issuance of additional Common Shares or other equity securities of equal or senior rank would have the following effects:

● our existing shareholders’ proportionate ownership interest in Algoma may decrease;

● the amount of cash available per share, including for payment of dividends in the future, may decrease;

● the relative voting strength of each previously outstanding Common Share may be diminished; and

● the market price of Common Shares may decline.

- 51 -

The price of our Common Shares may be volatile and may decline regardless of our operating performance.

The market price of the Common Shares may fluctuate significantly in response to numerous factors and may continue to fluctuate for these and other reasons, many of which are beyond our control, including:

● actual or anticipated fluctuations in our revenue and results of operations;

● our ability to successfully transition to EAF steelmaking;

● accidents or other events that contribute to shutdowns of our facilities;

● the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

● failure of securities analysts to maintain coverage of Algoma, changes in financial estimates or ratings by any securities analysts who follow Algoma or its failure to meet these estimates or the expectations of investors;

● announcements by Algoma or its competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures, results of operations or capital commitments;

● changes in operating performance and stock market valuations of other steel companies;

● price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole, including periods of high inflation and high interest rates;

● trading volume of the Common Shares;

● the inclusion, exclusion or removal of the Common Shares from any indices;

● changes in our board of directors or management;

● transactions in the Common Shares by directors, officers, affiliates and other major investors;

● lawsuits threatened or filed against us;

● changes in laws or regulations applicable to our business;

● changes in our capital structure, such as future issuances of debt or equity securities;

● short sales, hedging and other derivative transactions involving our capital stock;

● general economic conditions in the United States and Canada;

● pandemics or other public health crises;

● other events or factors, including those resulting from war, incidents of terrorism or responses to these events; and

● the other factors described in this “Risk Factors” section.

The stock market has recently experienced extreme price and volume fluctuations. The market prices of securities of companies have experienced fluctuations that often have been unrelated or disproportionate to their operating results. In the past, stockholders have sometimes instituted securities class action litigation against companies following periods of volatility in the market price of their securities. Any similar litigation against us could result in substantial costs, divert our management’s attention and resources, and harm our business, financial condition, and results of operations.

An active, liquid trading market for Common Shares and Warrants may not be maintained, which may limit your ability to sell Common Shares and Warrants.

Although the Common Shares and Warrants are currently listed on Nasdaq and the TSX, an active, liquid trading market for Common Shares and Warrants may not be sustained. A public trading market having the desirable characteristics of depth, liquidity and orderliness depends upon the existence of willing buyers and sellers at any given time, such existence being dependent upon the individual decisions of buyers and sellers over which neither we nor any market maker has control. The failure of an active and liquid trading market to continue would likely have a material adverse effect on the value of Common Shares and Warrants. The market price of Common Shares may decline, and you may not be able to sell your Common Shares at or above the price at which you purchased them, or

- 52 -

at all. An inactive market may also impair our ability to raise capital to continue to fund operations by issuing Common Shares or Warrants.

A significant portion of our total outstanding Common Shares may be sold into the market at any time. This could cause the market price of Common Shares and Warrants to drop significantly, even if our business is doing well.

Sales of a substantial number of Common Shares and Warrants in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of holders intend to sell Common Shares or Warrants, could reduce the market price of Common Shares or Warrants. No existing lock-up remains in place with respect to securities issued as a result of the Merger and, moreover, certain holders of our securities continue to have certain registration rights with respect to their securities. Such sales by such holders could be significant. As restrictions on resale end, the market price of Common Shares and Warrants could decline if the holders of currently restricted Common Shares or Warrants sell them or are perceived by the market as intending to sell them. Any issuance of preferred shares could make it difficult for another company to acquire us or could otherwise adversely affect shareholders, which could depress the price of the Common Shares.

Any issuance of preferred shares could make it difficult for another company to acquire us or could otherwise adversely affect shareholders, which could depress the price of the Common Shares.

Our board of directors has the authority to issue preferred shares and to determine the preferences, limitations, and relative rights of preferred shares and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by our shareholders. Our preferred shares could be issued with liquidation, dividend, and other rights superior to the rights of the Common Shares. The potential issuance of preferred shares may delay or prevent a change in control of us, discourage bids for the Common Shares at a premium over the market price and adversely affect the market price and other rights of the holders of the Common Shares.

Changes to tax laws may have an adverse impact on holders of the Common Shares.

Changes from time-to-time in the interpretation of, amendments to, or guidance relating to, existing tax laws, or the introduction of new tax legislation may have a material adverse effect on us and on the value of the Common Shares. Changes in enacted tax rates, legislation or regulations, and the Company’s interpretations of income tax legislation may result in material tax adjustments. In addition, the Company and tax authorities could disagree on tax filing positions and any reassessment of the Company’s tax filings could result in material adjustments of tax expense, income taxes payable and deferred income taxes.

If securities or industry analysts publish inaccurate or unfavourable research about us or our business, our trading price and volume could decline.

The trading market for the Common Shares will depend in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrade the Common Shares or publish inaccurate or unfavourable research about our business, our trading price may decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for the Common Shares could decrease, which could cause our trading price and volume to decline.

DIVIDENDS

For each quarter commencing with the quarter ended March 31, 2022, Algoma has paid a quarterly dividend payment of US$0.05 per Common Share to its shareholders. The determination to pay dividends in the future will depend on many factors, including, among others, Algoma’s financial condition, current and anticipated cash requirements,

- 53 -

contractual restrictions and financing agreement covenants, solvency tests imposed by applicable corporate law and other factors that Algoma’s board of directors may deem relevant.

DESCRIPTION OF CAPITAL STRUCTURE

The following description of our share capital summarizes certain provisions contained in the restated articles of Algoma (the “Restated Articles”). These summaries do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of our Restated Articles, which have been filed under the Company’s profiles on SEDAR+ at www.sedarplus.com and on the SEC’s EDGAR website at www.sec.gov.

Description of Common Shares

General

This section summarizes the material rights of shareholders of Algoma under the BCA and the material provisions of the Restated Articles.

Share Capital

The authorized share capital of Algoma consists of an unlimited number of Common Shares without par value and an unlimited number of preferred shares without par value issuable in series (the “Algoma Preferred Shares”).

As of March 31, 2024, there were 104,103,072 Common Shares issued and outstanding, and no Algoma Preferred Shares issued and outstanding.

Under the Restated Articles, holders of the Common Shares are entitled to receive notice of, and to attend and vote at all meetings of shareholders, except meetings at which only holders of a specified class of shares are entitled to vote. Each Common Share entitles its holder to one vote. Under the Restated Articles, Algoma’s board of directors has the authority to create and issue one or more series of Algoma Preferred Shares, with such special rights and restrictions to be attached to such series as are authorized by the directors of Algoma.

Dividend Rights

Under the BCA, a corporation may pay a dividend out of profits, capital or otherwise: (1) by issuing shares or warrants by way of dividend or (2) in property, including money. Further, under the BCA, a corporation cannot declare or pay a dividend if there are reasonable grounds for believing that the corporation is insolvent or payment of the dividend would render the corporation insolvent.

Holders of Common Shares will be entitled to receive dividends as and when declared by Algoma’s board of directors at its discretion out of funds properly applicable to the payment of dividends, subject to the rights, if any, of shareholders holding shares with special rights to dividends. The timing, declaration, amount and payment of future dividends will depend on our financial condition, earnings, capital requirements and debt service obligations, as well as legal requirements, regulatory constraints, industry practice and other factors that Algoma’s board of directors deems relevant. Under the Restated Articles, a resolution declaring a dividend may direct payment of the dividend wholly or partly by the distribution of specific assets or of fully paid shares or of bonds, debentures or other securities of Algoma, or in any one or more of those ways.

- 54 -

Subject to the special rights and restrictions attached to the Algoma Preferred Shares, the holders of Common Shares shall receive the remaining property of Algoma upon dissolution in equal rank with the holders of all other Common Shares.

Pre-emptive Rights

There are no pre-emptive rights relating to Common Shares.

Amendment of Notice of Articles and Articles and Alteration of Share Capital

Under the BCA, Algoma may amend the Restated Articles by (1) the type of resolution specified in the BCA, (2) if the BCA does not specify a type of resolution, then by the type specified in the Restated Articles, or (3) if the Restated Articles do not specify a type of resolution, then by special resolution, which requires two-thirds of the votes cast by shareholders in order to pass. The BCA permits many substantive changes to a corporation’s articles (such as a change in the corporation’s authorized share structure or a change in the special rights or restrictions that may be attached to a certain class or series of shares) to be changed by the resolution specified in that company’s articles. The Restated Articles provide that alterations to Algoma’s authorized share structure (other than a subdivision or consolidation of all or any of its shares) and the applicable alteration to its Notice of Articles may be authorized by special resolution. A subdivision or consolidation of all or any of its shares or a change in Algoma’s name may be authorized by a resolution of the directors. Furthermore, the Restated Articles state that, if the BCA does not specify the type of resolution required for an alteration, and if the Restated Articles do not specify a type of resolution, Algoma may resolve to alter the Restated Articles by ordinary resolution, which requires a majority of shareholder votes cast in order to pass.

Dissent Rights

Under the BCA, shareholders of a corporation are entitled to exercise dissent rights in respect of certain matters and to be paid the fair value of their shares in connection therewith. The dissent right is applicable where the company resolves to: (1) alter its articles to alter the restrictions on the powers of the company or on the business it is permitted to carry on; (2) approve certain amalgamations; (3) approve a statutory arrangement, where the terms of the arrangement permit dissent; (4) sell, lease or otherwise dispose of all or substantially all of its undertaking; or (5) continue the company into another jurisdiction. The BCA provides that beneficial owners of shares who wish to exercise their dissent rights with respect to their shares must dissent with respect to all of the shares beneficially owned by them, whether or not they are registered in their name.

Annual Meetings

The Restated Articles provide that, unless an annual general meeting is deferred or waived in accordance with the BCA, Algoma must hold its first annual general meeting within 18 months after the date on which it was incorporated or otherwise recognized, and after that must hold an annual general meeting at least once in each calendar year and not more than 15 months after the last annual reference date at such time and place as may be determined by the directors. An annual general meeting may be partially or entirely virtual.

Board and Shareholder Ability to Call Special Meetings

The Restated Articles provide that meetings of the shareholders may be called by the board of directors at any time. In addition, under the BCA, the holders of not less than 5% of the issued shares of a corporation that carry the right to vote at a general meeting may requisition that the directors call a meeting of shareholders for such purposes as stated in the requisition. Upon meeting the technical requirements set out in the BCA, the directors must, within 21 days after receiving the requisition, call a meeting of shareholders to be held not more than four months after receiving the

- 55 -

requisition. If the directors do not call such a meeting within 21 days after receiving the requisition, the requisitioning shareholders or any of them holding in aggregate more than 2.5% of the issued shares of the company that carry the right to vote at general meetings may send notice of a meeting to be held to transact the business stated in the requisition.

Shareholder Meeting Quorum

The Restated Articles provide that two persons who are, or who represent by proxy, shareholders who, in the aggregate, hold at least 25% of the issued shares of Algoma entitled to be voted at the meeting, constitute a quorum at any annual or special meeting of the shareholders.

Voting Rights

Under the BCA, at any meeting of shareholders at which a quorum is present, any action that must or may be taken or authorized by the shareholders, except as otherwise provided under the BCA and Restated Articles, may be taken or authorized by an “ordinary resolution,” which is a simple majority of the votes cast by shareholders voting shares that carry the right to vote at general meetings. The Restated Articles provide that every motion put to a vote at a meeting of shareholders will be decided by a show of hands or the functional equivalent unless a poll is directed by the chair or demanded by any shareholder entitled to vote who is present in person or by proxy. Votes by a show of hands or functional equivalent result in each person having one vote (regardless of the number of shares such person is entitled to vote). If voting is conducted by poll, each holder of Common Shares is entitled to one vote for each Common Share held.

There are no limitations on the right of non-resident or foreign owners to hold or vote Algoma securities imposed by Canadian law or by the charter or other constituent document of Algoma.

Shareholder Action by Written Consent

Under the BCA, shareholder action without a meeting may be taken by a “consent resolution” of shareholders, which requires that, after being submitted to all shareholders entitled to vote at a general meeting, the resolution is consented to in writing by: (1) in the case of a matter that would normally require an ordinary resolution, shareholders who, in the aggregate, hold shares carrying at least 66 2/3% of the votes entitled to be cast on such consent resolution, or (2) in the case of any other resolution of the shareholders, all of the shareholders entitled to vote on such resolution. A consent resolution of shareholders is deemed to be a proceeding at a meeting of those shareholders and to be as valid and effective as if it had been passed at a meeting of shareholders that satisfies all the requirements of the BCA and its related regulations, and all the requirements of the Restated Articles, relating to meetings of shareholders.

Inspection of Corporation Records

Algoma must keep at its records office, or at such other place as the BCA may permit, the documents, copies, registers, minutes and other records which Algoma is required by the BCA to keep at such places. Algoma must keep adequate accounting records to record properly its financial affairs and condition in compliance with the provisions of the BCA. Under the BCA, any director or shareholder may, without charge, inspect certain of Algoma’s records at Algoma’s records office or such other place where such records are kept during the corporation’s statutory business hours. Former shareholders and directors may also inspect certain records, free of charge, but only those records pertaining to the times that they were shareholders or directors. Further, a public company must allow all persons to inspect certain records of the company free of charge. As permitted by the BCA, the Restated Articles prohibit shareholders from inspecting any accounting records of Algoma, unless the directors determine otherwise.

- 56 -

Election and Appointment of Directors

The Restated Articles do not provide for the board of directors to be divided into classes.

Pursuant to the Restated Articles, any casual vacancy occurring on the board of directors may be filled by the remaining directors. If Algoma has fewer directors in office than the number set by the Restated Articles as the necessary quorum for the directors, the directors may only act for the purpose of appointing directors up to that number or of calling a meeting of shareholders for the purpose of filling any vacancies on the board of directors. If Algoma has no directors or fewer directors in office than the number set by the Restated Articles as the necessary quorum for the directors, the shareholders may elect or appoint, by ordinary resolution, directors to fill the vacancies on the board. Pursuant to the Restated Articles, the Algoma directors may appoint one or more additional directors, but the number of additional directors shall not exceed one third the number of the first directors and, thereafter, one third of the number of current directors who were elected or appointed other than as such additional directors. The filling of a casual vacancy by the Algoma directors shall not be counted against such cap.

Removal of Directors

Pursuant to the Restated Articles, the shareholders of Algoma may remove any director before the expiration of his or her term of office by special resolution, which requires a special majority requirement of two-thirds of the votes cast in favor of the resolution. In that event, the shareholders may elect, or appoint by ordinary resolution, another individual as director to fill the resulting vacancy. If the shareholders do not appoint a director to fill the vacancy contemporaneously with removal, then either the directors or the shareholders by ordinary resolution may appoint an additional director to fill that vacancy.

The directors of Algoma may remove a director before the expiration of his or her period of office if the director is convicted of an indictable offence or otherwise ceases to qualify as a director and the directors may appoint a director to fill the resulting vacancy.

Proceedings of Board of Directors

A resolution of the directors or of any committee of the directors consented to in writing by all of the directors entitled to vote on it is as valid and effective as if it had been passed at a meeting of the directors or of the committee of the directors duly called and held.

Requirements for Advance Notification of Shareholder Nominations

Pursuant to the Restated Articles, shareholders of record may nominate persons for election to our Board only by providing notice to Algoma’s secretary that is both timely and in proper written form. To be timely, a shareholder’s notice shall be received by the secretary of Algoma (a) in the case of an annual general meeting of shareholders, not less than 30 days prior to the date of the annual general meeting of shareholders; provided, however, that in the event that the annual general meeting of shareholders is to be held on a date that is less than 50 days after the date (the “Notice Date”) on which the first public announcement of the date of the annual general meeting was made, notice by the nominating shareholder may be made not later than the close of business on the tenth day following the Notice Date, and (b) in the case of a special meeting (which is not also an annual general meeting) of shareholders called for the purpose of electing directors (whether or not called for other purposes as well), not later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting of shareholders was made. To be in proper written form, such notice must include, among other information, certain information with respect to each proposed nominee and each shareholder nominating persons for elections to the Board and must disclose about any contract, agreement, arrangement, understanding or relationship pursuant to which the nominating shareholder has a right to vote shares of Algoma or between the proposed nominee and the nominating

- 57 -

shareholder and any other information relating to the proposed nominee or nominating shareholder that would be required to be disclosed in a dissident’s proxy circular under applicable securities laws.

Approval of Mergers and Other Corporate Transactions

Under the BCA, certain corporate actions, such as: (1) amalgamations (other than with certain affiliated corporations); (2) continuances; (3) sales, leases or exchanges of all, or substantially all, the undertaking of a corporation other than in the ordinary course of business; (4) reductions of paid-up capital for any purpose, e.g. in connection with the payment of special distributions (subject, in certain cases, to the satisfaction of solvency tests); and (5) other actions such as liquidations or arrangements, are required to be approved by “special resolution.” A “special resolution” is a resolution passed by not less than two-thirds of the votes cast by the shareholders who voted in respect of the resolution or signed by all shareholders entitled to vote on the resolution.

In certain cases where share rights or special rights may be prejudiced or interfered with, a special separate resolution of shareholders of the affected class or series, including a class or series of shares not otherwise carrying voting rights, to approve the corporate action in question is also required. In specified extraordinary corporate actions, such as approval of plans of arrangement and amalgamations, all shares have a vote, whether or not they generally vote and, in certain cases, have separate class votes.

Limitations on Director Liability

Under the BCA, no provision in a contract or the articles may relieve a director or officer from (1) the duty to act in accordance with the BCA and its related regulations, or (2) liability that by virtue of any enactment or rule of law or equity would otherwise attach to that director or officer in respect of any negligence, default, breach of duty or breach of trust of which the director or officer may be guilty in relation to a corporation.

A director is not liable under the BCA for certain acts if the director relied, in good faith, on (1) financial statements of the corporation represented to the director by an officer of the corporation or in a written report of the auditor of the corporation to fairly reflect the financial position of the corporation, (2) a written report of a lawyer, accountant, engineer, appraiser or other person whose profession lends credibility to a statement made by that person, (3) a statement of fact represented to the director by an officer of the corporation to be correct, or (4) any record, information or representation that the court considers provides reasonable grounds for the actions of the director, whether or not the record was forged, fraudulently made or inaccurate or the information or representation was fraudulently made or inaccurate. Further, a director is not liable for certain acts if the director did not know and could not reasonably have known that the act done by the director or authorized by the resolution voted for or consented to by the director was contrary to the BCA.

Derivative Actions and Other Remedies

Under the BCA, a complainant (a director or shareholder of a corporation, which includes a beneficial shareholder, and any other person that a court considers to be an appropriate person to make such an application) may apply to the Supreme Court of the Province of British Columbia for leave to bring an action in the name and on behalf of Algoma for the purpose of prosecuting or defending an action on behalf of Algoma.

The court may grant leave if: (1) the complainant has made reasonable efforts to cause the directors of Algoma to prosecute or defend the action; (2) notice of the application for leave has been given to Algoma and any other person that the court may order; (3) the complainant is acting in good faith; and (4) it appears to the court to be in the best interests of Algoma for the action to be brought, prosecuted or defended.

- 58 -

Under the BCA, the court in a derivative action may make any order it determines to be appropriate. In addition, under the BCA, a court may order a corporation to pay the shareholder’s interim costs, including legal fees and disbursements. However, the shareholder may be held accountable for the costs on final disposition of the action.

The BCA also contains an oppression remedy, which enables a court to make almost any order to rectify the matters complained of if the court is satisfied upon application by a shareholder (including a beneficial shareholder and any other person that the court considers to be an appropriate person to make such an application) that the affairs of Algoma are being or have been conducted, or that the powers of the directors are being or have been exercised, in a manner that is oppressive to one or more shareholders, or that some action has been or may be taken that is unfairly prejudicial to one or more shareholders. The applicant must be one of the persons being oppressed or prejudiced and the application must be brought in a timely manner.

The oppression remedy provides the court with extremely broad and flexible jurisdiction to intervene in corporate affairs to protect shareholders. While conduct that is in breach of fiduciary duties of directors or that is contrary to the legal right of a complainant would normally be expected to trigger the court’s jurisdiction under the oppression remedy, the exercise of that jurisdiction does not depend on a finding of a breach of such legal and equitable rights.

Exclusive Forum

The Restated Articles do not provide for an exclusive forum.

Description of Warrants

Each Warrant currently entitles the registered holder to purchase one Common Share at a price of $11.50 per share, subject to adjustment as discussed below, at any time. However, no Warrants will be exercisable for cash unless Algoma has an effective and current registration statement covering the Common Shares issuable upon exercise of the Warrants and a current prospectus relating to such Common Shares, which Algoma currently has an intends to maintain. Notwithstanding the foregoing, during any period when we shall have failed to maintain an effective registration statement covering the Common Shares issuable upon exercise of the Public Warrants, warrant holders may, until such time as there is an effective registration statement, exercise Warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the U.S. Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their Warrants on a cashless basis. In the event of such cashless exercise, each holder would pay the exercise price by surrendering the Warrants for that number of Common Shares equal to the quotient obtained by dividing (x) the product of the number of Common Shares underlying the Warrants, multiplied by the difference between the exercise price of the Warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average reported last sale price of the Common Shares for the 5 trading days ending on the trading day prior to the date of exercise. The Warrants will expire on the fifth anniversary of the completion of the Merger, or October 19, 2026, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Private Warrants are identical to the Public Warrants except that the Private Warrants are exercisable for cash or on a cashless basis, at the holder’s option, and are not redeemable by Algoma, in each case so long as they are still held by the founders of Legato, EarlyBirdCapital, or their permitted transferees.

We may call the Warrants for redemption (excluding the Private Warrants), in whole and not in part, at a price of $0.01 per Warrant,

● at any time after the Warrants became exercisable,

● upon not less than 30 days’ prior written notice of redemption to each Warrant holder,

- 59 -

● if, and only if, the reported last sale price of the Common Shares equals or exceeds $18.00 per Common Share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations), for any 20 trading days within a 30 trading day period commencing at any time after the Warrants become exercisable and ending on the third business day prior to the notice of redemption to warrant holders; and

● if, and only if, there is a current registration statement in effect with respect to the Common Shares underlying such Warrants.

The right to exercise will be forfeited unless the Warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a Warrant will have no further rights except to receive the redemption price for such holder’s Warrant upon surrender of such Warrant.

The redemption criteria for the Warrants have been established at a price which is intended to provide warrant holders a reasonable premium to the initial exercise price and provide a sufficient differential between the then-prevailing Common Share price and the Warrant exercise price so that if the Common Share price declines as a result of a redemption call, the redemption will not cause the Common Share price to drop below the exercise price of the Warrants.

If we call the Warrants for redemption as described above, our management will have the option to require all holders that wish to exercise Warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the Warrants for that number of Common Shares equal to the quotient obtained by dividing (x) the product of the number of Common Shares underlying the Warrants, multiplied by the difference between the exercise price of the Warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose shall mean the average reported last sale price of the Common Shares for the 5 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of Warrants.

The Warrants are in registered form and are governed by a Warrant Agreement (the “Warrant Agreement”) between Continental Stock Transfer & Trust Company, as warrant agent, and Legato, as amended and assigned to Algoma pursuant to an amendment agreement, dated as of the closing of the Merger, among Algoma, Legato, Continental Stock Transfer & Trust Company, as warrant agent and TSX Trust Company, as Canadian co-warrant agent. The Warrant Agreement will provides that the terms of the Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval, by written consent or vote, of the holders of at least a majority of the then outstanding Warrants in order to make any change that adversely affects the interests of the registered holders.

The exercise price and number of Common Shares issuable on exercise of the Warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary dividend or Algoma’s recapitalization, reorganization, merger or consolidation. However, except as described below, the Warrants will not be adjusted for issuances of Common Shares at a price below their respective exercise prices.

The Warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of Warrants being exercised. The warrant holders do not have the rights or privileges of holders of Common Shares and any voting rights until they exercise their Warrants and receive Common Shares. After the issuance of Common Shares upon exercise of the Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by shareholders.

- 60 -

Warrant holders may elect to be subject to a restriction on the exercise of their Warrants such that an electing Warrant holder would not be able to exercise their Warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 9.8% of the Common Shares outstanding.

AGREEMENTS WITH SHAREHOLDERS

Voting Rights

In connection with the consummation of our Merger with Legato, we entered into an Investor Rights Agreement pursuant to which, among other things, certain IRA Parties that previously had board designation rights with respect to Algoma Steel Holdings Inc. have the right to nominate, in the aggregate, four directors to our board for so long as they beneficially own at least 7.36% of our outstanding Common Shares. See “Risk Factors - Our Investor Rights Agreement provides certain IRA Parties the right to nominate up to four of our directors.”– Investor Rights Agreement”. As of the date of this Annual Information Form, none of the IRA Parties meet the requisite ownership threshold required to nominate a director for election to our board, and, in addition, the we have been advised that one of the IRA Parties, Barclays Bank PLC, has permanently surrendered its nomination rights under the Investor Rights Agreement.

Investor Rights Agreement

On October 19, 2021, Algoma, the IRA Parties entered into an Investor Rights Agreement. The Investor Rights Agreement provides that the Warrants and Common Shares held by the IRA Parties, including the Common Shares issuable upon the exercise of Warrants and other derivative securities, shall bear customary registration rights and nomination rights. Specifically, Algoma agreed to file a registration statement as soon as practicable upon a request from certain IRA Parties to register the resale of certain registrable securities under the U.S. Securities Act and applicable Canadian securities laws, subject to required notice provisions to other IRA Parties; provided, Algoma shall not be obligated to effect a demand registration (i) unless the aggregate proceeds expected to be received from the sale of the registrable securities equals or exceeds C$50,000,000 or (ii) if Algoma has effected a demand registration within the six-month period prior to receipt of the request therefor. Algoma also agreed to provide customary “piggyback” registration rights with respect to any valid demand registration request. Algoma will pay certain expenses relating to such registrations and indemnify the IRA Parties against certain liabilities. Additionally, certain IRA Parties that currently have board designation rights with respect to Algoma Steel Holdings Inc. will have the right to nominate, in the aggregate, four directors to the Algoma board for so long as they beneficially own at least 7.36% of our outstanding Common Shares.

Indemnification Agreements

We have entered into indemnification agreements with our directors and certain officers to indemnify such individuals, to the fullest extent permitted by law and subject to certain limitations, against all liabilities, costs, charges and expenses reasonably incurred by such individuals in an action or proceeding to which any such individual was made a party by reason of such party being or having been (i) an officer or director of (i) Algoma, or (ii) an officer or director of another corporation, or a similar role with another entity, including a partnership, trust, joint venture or other unincorporated entity, if such party serves such organization at Algoma’s request.

In addition to paying interest on outstanding principal under the Revolving Credit Facility, the Company is required to pay a commitment fee in respect of unutilized commitments and a letter of credit fee and facing fee in respect of outstanding letters of credit. These fees are payable quarterly in arrears.

Algoma is exposed to interest rate benchmark, CDOR, which is subject to interest rate benchmark reform. The exposure arises on financial liabilities bearing interest at CDOR plus basis points including Algoma’s Revolving Credit Facility. Algoma is closely monitoring the market and the output from the various industry working groups managing the transition to new benchmark interest rates including announcements made by the Canadian Alternative Reference Rate Working Group.

The referenced benchmark rates applicable to Algoma are expected to be published until at least June of 2024 and prior to their expiry, Algoma will work with the administrative agent of its various CDOR exposed credit agreements to replace CDOR with a fallback reference rate at similar commercial terms to today’s rates.

Availability and repayments

Availability under the Revolving Credit Facility is governed by a conventional borrowing base calculation comprised of eligible accounts receivable, eligible inventory and cash, subject to various customary reserves. We are required to maintain a minimum borrowing base. Any shortfall in the borrowing base will trigger a mandatory loan repayment in the amount of the shortfall, subject to certain cure rights.

Maturity

The Revolving Credit Facility has a maturity date of May 23, 2028.

Guarantees and security

All obligations under the Revolving Credit Facility are required to be jointly and severally guaranteed by Algoma Steel Intermediate Holdings Inc. and each of ASI’s subsidiaries on a first lien secured basis.

Certain Covenants and Events of Default

The Revolving Credit Facility contains covenants that, among other things, restrict, subject to certain exceptions, our ability to:

● incur liens;

● engage in mergers, consolidations or amalgamations;

● make certain investments or acquisitions;

- 74 -

● make certain restricted payments, including the payment of dividends, the repurchase of our capital stock, and the repayment of junior indebtedness prior to maturity;

● incur additional indebtedness;

● engage in certain transactions with our affiliates;

● amend or modify certain indebtedness;

● sell or transfer assets;

● in the case of Algoma Steel Intermediate Holdings Inc., engage in any material business or operations; and

● make changes to our defined benefit pension plans.

In addition, if availability under the Revolving Credit Facility falls below a specified threshold, we are required to maintain compliance with a springing minimum fixed charge coverage ratio test of 1.00:1.00.

The Revolving Credit Facility also contains certain customary affirmative covenants and events of default, including an event of default upon the occurrence of a change of control.

Green Steel Funding

On September 20, 2021, the Company secured an agreement with the Minister of Industry of the Government of Canada, whereby we will receive up to C$200.0 million in the form of a loan to support our EAF Transformation (the “Federal SIF EAF Loan”). The loan is provided through the Net Zero Accelerator initiative of the Federal Strategic Innovation Fund. The Federal SIF EAF Loan is guaranteed by ASGI. The repayment period will commence upon the earlier of the Company having access to full power from the grid to operate the EAFs independently, or January 1, 2030. The annual repayment is further dependent on our performance in reducing GHG emissions. As of March 31, 2024, the Company had applied for reimbursements of C$139.9 million and recognized a benefit, net of accretion, in respect of the SIF EAF Funding of C$86.4 million. Accordingly, C$139.9 million was outstanding on the SIF EAF Funding as of March 31, 2024, and the carrying value of the SIF EAF Funding was C$53.5 million as of such date.

On November 29, 2021 the Company, entered into an agreement of which a benefit of up to C$220.0 million would flow to the Company in the form of a loan from the Canada Infrastructure Bank (“CIB”). CIB is a federal Crown corporation established under the Canada Infrastructure Bank Act which is not an agency of the government of Canada, but is accountable to the government of Canada through the Minister of Infrastructure and Communities. Under the terms of the CIB agreement, the Company had the option to draw on a non-revolving construction credit facility. As at December 31, 2023, the Company has not drawn on this credit facility, and on March 7, 2024 the CIB Facility was terminated.

The Company has recognized the governmental loan claims receivable, governmental loan payable and benefit associated with these agreements because the Company has fulfilled its obligations under the respective agreements.

Overview of the Business

Algoma Steel Group Inc., formerly known as 1295908 B.C. Ltd. (the “Company”), was incorporated on March 23, 2021 under the Business Corporations Act of British Columbia solely for the purpose of purchasing Algoma Steel Holdings Inc. On May 24, 2021, the Company entered into a Merger Agreement (the “Merger”), by and among the Company, a wholly-owned subsidiary of the Company and Legato Merger Corp. (“Legato”). On October 19, 2021, the Company completed its merger with Legato, listing its common shares and warrants under the symbol ‘ASTL’ and ASTLW’, respectively, on the Toronto Stock Exchange (TSX) and the Nasdaq Stock Market (“Nasdaq”). Algoma Steel Group Inc. is the ultimate parent holding company of Algoma Steel Inc. and does not conduct any business operations.

Algoma Steel Inc. (“ASI”), the operating company and a wholly-owned subsidiary of Algoma Steel Holdings Inc., was incorporated on May 19, 2016 under the Business Corporations Act of British Columbia. ASI is an integrated steel producer with its active operations located entirely in Sault Ste. Marie, Ontario, Canada. ASI produces sheet and plate products that are sold primarily in Canada and the United States.

Strategic Initiatives

Electric Arc Furnace (“EAF”) Transformation Project

On November 10, 2021, the Company’s Board of Directors authorized the Company’s transformation to electric arc steelmaking (the “EAF Transformation Project”), including the construction of two state-of-the-art electric-arc-furnaces to replace its existing No. 7 blast furnace and steelmaking operations (“BF7 Steelmaking”). The EAF Transformation Project is expected to reduce Algoma’s carbon emissions by approximately 70%.

EAF steelmaking is a method of producing steel by melting scrap metal and other metallic inputs using an electric arc. This process is widely used in modern steel production. The EAF steelmaking facility is being built on vacant land adjacent to the current steelmaking facility to mitigate disruption to current operations and will be integrated into existing downstream equipment and facilities, thereby reducing capital expenditure requirements.

The EAF Transformation Project is expected to improve product mix, reduce fixed costs, provide significant carbon tax savings, increase production capacity and decrease the Company’s environmental footprint. The Company anticipates a 30-month construction phase for the EAF facility, with construction having started in April 2022 and commencement of commissioning activities to begin prior to calendar year-end 2024, and beginning to scale-up EAF operations thereafter. The Company has approval from the electricity regulators to connect the EAFs to the current 115kV electricity grid with the internal power generation asset known as Lake Superior Power (the “LSP Plant”). As the EAFs are scaled-up after commissioning, Algoma anticipates reduced dependency on its legacy BF7 Steelmaking operations.

The following paragraphs outline key elements and milestones of the EAF Transformation Project:

Technology

On December 2, 2021, the Company announced that it had selected Danieli & C. Officine Meccaniche S.p.A. (“Danieli”) as the sole technology provider for the EAF steelmaking facility. In connection with this agreement, Danieli will supply its latest technology solutions including AC-Digimelter technology powered by Q-One digital power systems and Q-SYM automated scrap yard. Various EAF and power components have been received on the Company’s site ready for installation, including two EAF charging cranes with lifting capacity of 570 short tons each to facilitate further installation of the EAF components.

Construction and Environmental Permitting

The contract for the structural building housing the EAF Transformation Project was awarded on April 25, 2022, to Hamilton, Ontario-based Walters Group Inc. (“Walters”). Walters is responsible for fabricating and erecting the main building structure in addition to the necessary dust collection hoods. Pursuant to the fixed-price contract, Walters is using Algoma’s steel plate products in the fabrication of heavy structural

4

components, and will work with local industrial contractor, SIS Manufacturing Inc., for the fabrication of these key elements. As of March 31, 2024, approximately 90% of the EAF building structural steel has been erected.

On March 13, 2023, the Company announced the appointment of EllisDon as Construction Manager for completion of the EAF Transformation Project. The Construction Manager role is central to the successful planning, execution, and completion of the various construction projects. Their responsibilities encompass various aspects of project management and oversight to ensure that construction projects are completed safely, on time, within budget, and to the required quality standards.

The Company is progressing its applications for environmental operational permits through the Province’s Ministry of Environment, Conservation and Parks. The Company received ECA 5691-CJGK54 (as amended) for industrial sewage works for the disposal of process effluent and non-contact cooling water. Algoma will be subject to an Integrated Mill Technical Standard for air contaminants compliance until we are 100% EAF cold-charged metallics.

Budget and Project Financing

As previously updated, the Company plans to invest approximately C$825-C$875 million in the EAF Transformation Project, funded with previously announced financing commitments below, proceeds from the Merger, cash on hand and cash from operations.

The Company previously secured an agreement with the Government of Canada through the Ministry of Innovation, Science and Economic Development Canada (ISED), whereby the Company will receive up to C$200.0 million in the form of a loan to support the EAF Transformation Project. The loan is provided through the Net Zero Accelerator Initiative of the Federal Strategic Innovation Fund (the “Federal SIF” and such loan, the “Federal SIF EAF Loan”). The repayment period will commence upon the earlier of the Company having access to full power from the provincial electricity grid to operate the EAF independently, or January 1, 2030. The annual repayment is further dependent on the Company’s performance in reducing its GHG emissions. As of March 31, 2024, the Company has received C$139.9 million from the Federal SIF EAF Loan.

In addition, the Company previously entered into an agreement (the “CIB Loan”) with the Canada Infrastructure Bank (“CIB”) with access up to C$220 million in loan financing towards the EAF Transformation Project. Pursuant to its terms, the CIB credit availability was reduced as a result of share repurchases and dividends paid by the Company, and the loan was undrawn as of March 31, 2024 with limited credit availability remaining. Given that the Company did not expect to draw on the CIB Loan, the parties agreed to terminate the agreement on March 7, 2024.

The EAF Transformation project continues to advance, with approximately $800 million of the budgeted project cost contracted. The Company continues to expect that the completion of the EAF project will be funded with cash-on-hand, cash generated through operations, and available borrowings under the Company’s existing undrawn credit facility.

From the inception of the EAF Transformation Project through March 31, 2024, the Company invested a total of C$562.8 million (excluding the benefit of Government loans). As of March 31, 2024, the Company had C$60.1 million in total available Government financing under the Federal SIF EAF Loan.

Access to Electricity

The Company upgraded its LSP Plant with two LM6000PC aeroderivative gas turbines, multiple control systems, and a full rewind of the No. 2 generator to provide 110-115 MW towards the operation of the EAFs. The LSP Plant combined with current 115kV grid power are expected to provide sufficient power to run both electric arc furnaces in an alternating mode, thereby allowing the Company to produce the same volume of steel as produced today from its BF7 Steelmaking operations. As of March 31, 2024, the Company has approval from the Independent Electricity System Operator (“IESO”) to connect the EAFs to the current 115kV electricity grid with the LSP Plant.

5

The Company is progressing its discussions with the IESO, Ontario independent electricity regulator, as well as with the Ministry of Energy in respect of securing more grid power to realize the full potential of the EAF Transformation Project. On September 28, 2023, the Company received conditional approval of the next phase of the Company’s EAF Connection Proposal (CAA ID: 2021-704), providing for connecting the EAF load facility with electricity supplied from the proposed local 230kV transmission line to be constructed and operated by PUC Transmission LP.

Significant progress has continued on long term regional power access for Northeast and Eastern Ontario. On October 23, 2023, the Ontario provincial government announced that it has issued an Order-in-Council declaring three regional transmission line projects as priorities, which includes one new line in eastern Ontario and two new lines in northeastern Ontario. These lines are expected to enable economic growth activities including among other things the production of clean steel at Algoma. The Order-in-Council will streamline the Ontario Energy Board’s (OEB) regulatory approval process for these lines. The government has also directed the OEB to amend Hydro One Network Inc. (Hydro One)’s transmission license to designate it as the transmitter responsible for the development of the three lines.

Iron Ore Extension

On October 2, 2023, the Company announced a two-year extension of its existing iron ore purchase contract with United States Steel Corporation (“U. S. Steel”) (NYSE: X), with an option to further extend for a third year solely at Algoma’s discretion. The extended purchase contract is anticipated to cover the expected volumes of iron ore required to complete Algoma’s transition from blast furnace to EAF steelmaking.

The extension with U. S. Steel represents another strategic milestone for Algoma as it continues on its transformative journey toward sustainable steel production through EAF steelmaking.

Plate Mill Modernization

In 2019, the Company started a plate mill modernization project (the “PMM Project”) which is to be completed in two phases and plans to invest a total of approximately C$135 million, which will be partly funded by government loan facilities totalling approximately C$50 million. This strategic initiative will enhance the capacity and quality of the Company’s discrete plate product line, which is a differentiated product capability and a key source of competitive advantage. The PMM Project will allow the Company to satisfy higher product quality requirements of its customers with respect to surface and flatness, increase high strength capability with availability of new grades, ensure reliability of plate production with direct ship capability and increase overall plate shipment capacity through debottlenecking and automation.

The modernization process is comprised of two phases: the first being a quality focus and the second phase a productivity focus. The first phase has been completed, and focused on quality, with installation and commissioning upgrades of a new primary slab de-scaler (to improve surface quality), automated surface inspection system (to detect and map surface quality), an in- line hot leveler (to improves flatness), and automation of the 166 inch plate mill (which expands the Company’s grade offering).

The second phase focuses on productivity enhancement and will be completed in two separate minor outages throughout 2024 to decrease commissioning risks and to provide for lesser impact to our customers. The Company has installed and is presently commissioning the inline dividing shear and plate piler. The first 20-day outage was successfully completed in April, 2024, and involved installation and commissioning upgrades of the new 4 HI DC drives, onboard descaling systems for the 2Hi roughing mill; mill alignment and work roll offset at the 4Hi mill; and new cooling beds coupling the plate mill and shear line, dividing shear, plate piler and automated marking machine. Work at the facility is now substantially complete and we expect any remaining minor items to be completed with other planned maintenance activities over the coming year.

Lime Production

In June 2023, the Company completed a C$15.4 million refurbishment project of its lime kiln production plant that processes limestone and other calcium carbonate-rich materials to produce quicklime (calcium oxide, CaO) and dolomitic lime (a mixture of calcium and magnesium oxides). Lime is an essential component of the steelmaking process, as it is used in various stages to remove impurities, control the slag composition, and adjust the chemical balance in the steelmaking process. The Company has a continuing and growing demand for lime product as it progresses through its transformation to EAF steelmaking.

Environmental Matters

Steel producers such as Algoma are subject to numerous environmental laws and regulations (“Environmental Law”), including federal and provincial, relating to the protection of the environment. The Company can incur regulatory liability as well as civil liability for contamination on-site (soil, groundwater, indoor air), contaminant migration and impacts off-site including in respect of groundwater, rivers, lakes, other waterways, and air emissions.

On June 9, 2022, the Company experienced an incident where an oil-based lubricant was released from our hot mill in Sault Ste. Marie. The oil entered our water treatment facility, and some quantity of the oil was discharged into the St. Mary’s River. Following the discharge, traffic on the river was temporarily halted, the local public health authority issued a water advisory and a nearby municipality issued a precautionary emergency declaration regarding its municipal water supply. We actively worked with our response partners deploying equipment and resources to contain and mitigate the effects on the waterway and neighboring communities and to clean up the released oil, while working with local, provincial, and federal regulatory authorities. The public health authorities lifted the water advisory on June 21, 2022 and the US Coast Guard did not see any impact to shoreline or marine wild life. The provincial and federal regulators each investigated this incident. The Company was recently served with one charge under the provincial Environment Protection Act and one charge under the provincial Ontario Water Resources Act in connection with the incident.

Fatal Incident Involving an Employee of a Contractor

On June 16, 2023, the Company reported a fatal incident involving an employee of a contractor who was retained to perform specialized maintenance work cleaning an out-of-service gas line. The Company investigated the fatal accident internally and worked with provincial authorities as they investigated. The Company was recently served with three charges under the provincial Occupational Health & Safety Act in connection with the fatality.

Environmental, Social and Governance (“ESG”) Report

On September 12, 2023 Algoma published its inaugural ESG report, marking a significant milestone in our journey towards sustainable and responsible business practices. We plan to publish an ESG report annually. At Algoma, we firmly acknowledge that ESG factors encompass a broad spectrum of risks and opportunities, impacting not only our organization but also our valued stakeholders, including investors, customers, suppliers, employees, governments, and the communities where we operate. Our unwavering commitment is to conduct our business activities with careful and conscientious consideration of these ESG factors.

Our vision extends beyond mere corporate responsibility; we aspire to play a pivotal role in shaping a sustainable and environmentally responsible future for Canadian steel production. Algoma has embarked on a transformative investment in EAF steelmaking, a significant step towards reducing our environmental footprint. We pledge to continually innovate and incorporate eco-friendly practices throughout our production processes. Simultaneously, we remain steadfast in our dedication to the health and safety of our workforce, the prosperity of communities we operate in, and the cultivation of a diverse, inclusive, and equitable workforce.

In development of our inaugural ESG report, we have conducted a comprehensive ESG materiality assessment. This rigorous assessment has enabled us to pinpoint and prioritize the ESG factors with the greatest potential to affect our business, ensuring that we generate lasting value for our investors while upholding our commitment to long-term sustainability. This foundational work forms the bedrock of our overarching ESG strategy.

7

Transparency and accountability are integral to our ESG journey. Our reporting aligns with the Sustainability Accounting Standards Board Standards and adheres to the recommendations of the Task Force on Climate-related Financial Disclosures to the greatest extent feasible. We are actively engaged in ongoing efforts to further harmonize our practices with these frameworks. This report provides comprehensive insights into our ESG strategy, outlines our approach to mitigating ESG risks, and underscores our commitment to harnessing ESG opportunities. Algoma notes that the ESG disclosure landscape has been evolving significantly over the past few years, notably through the establishment of the International Sustainability Standards Board (ISSB) and the ISSB’s issuance of the IFRS Sustainability Disclosure Standards, as well as the ongoing work of the Canadian Sustainability Standards Board. Algoma is committed to monitoring the evolving disclosure landscape, including regulatory requirements.

Our ESG approach is firmly underpinned by robust governance structures that empower us to effectively oversee and manage ESG-related risks and opportunities. Our Board of Directors assumes ultimate accountability for ESG factors, including those related to climate change. The Nominating and Corporate Governance Committee plays a pivotal role in supporting the Board by overseeing Algoma’s ESG framework, collaborating with other Board Committees, and reporting on ESG matters to the full Board.

At Algoma, our journey towards a sustainable and responsible future is not just a commitment; it’s a critical component of our strategy. We recognize that ESG excellence is integral to our continued success, and we remain resolute in our pursuit of a brighter, more sustainable future for all.

Impact on Operations

On January 20, 2024, a structural corridor carrying various utilities crucial for the company’s coke oven battery and blast furnace operations suffered an unexpected collapse. The collapse disrupted the flow of coke oven gas from the batteries to the rest of the steelworks, as well as a portion of the natural gas and oxygen flow to specific facilities, most critically the blast furnace. The unforeseen structural collapse did not result in any injuries, but for safety reasons, various areas near the collapse were evacuated and blast furnace operations were suspended at the time of the incident. Due to the unexpected shutdown and delayed restart, the blast furnace experienced operational challenges culminating in a chilled hearth, which suspended production for a period of three weeks, during which roughly 150,000 tons of hot metal production was lost. All necessary repairs to the blast furnace have been completed.

An independent investigation revealed an unforeseen escalating overload condition, resulting in a failure of a structural support member of the utility corridor, thereby causing the subsequent cascading collapse of other support structures. Minimal production of coke resumed at all three coke oven batteries on January 23, 2024 to maintain asset integrity. When combined with inventories on hand and the availability of third party coke supplies, the Company satisfied its coke requirements for normal steelmaking operations while the repairs to the utility corridor were completed. While significant progress has been made in the reconstruction of the utility corridor and commissioning of the suction main, and efforts have been undertaken to restore some operational functionality to the coke oven batteries; Coke production levels have not stabilized and the batteries are not yet fully operational.

The Company has standard insurance coverage that is intended to address events such as these, including business interruption and property damage insurance. The Company has engaged its insurers, and is in the process of submitting claims under its insurance policies for covered losses.

Management’s current estimate for the expected combined impact of lower revenues and higher costs for the duration of the outage is in the range of C$120.0 million to C$130.0 million. This impact is driven primarily by lost shipment volume restricted by lower blast furnace production. In addition, higher production costs experienced post-chill are driven by greater reliance on purchased furnace coke and natural gas, in the absence of normal volumes of internally produced coke and by-product gasses, along with greater utilization of purchased slabs. These higher costs were mitigated in part by lower labour cost enabled by a temporary partial layoff of unionized workers.

8

The Company and its insurers continue to review the impact of the structural collapse and subsequent lost production as it relates to the insurance claim. As a result, no related contingent gain has been recorded as of March 31, 2024.

Subsequent Event

On April 5, 2024, the Company’s indirect wholly-owned subsidiary, ASI, issued an aggregate of $350.0 million of 9.125% Senior Secured Second Lien Notes due April 15, 2029 (the “2029 Notes”). The 2029 Notes and related guarantees are secured by ASI’s immediate parent company and all of ASI’s subsidiaries on a second-priority liens basis over all assets that are now owned or hereafter acquired by the Company or any of the guarantors. subject to permitted liens and certain other exclusions described in the indenture governing the 2029 Notes. ASI intends to use the net proceeds from the offering of the 2029 Notes for general corporate purposes, adding strength and flexibility to its balance sheet.

Factors Affecting Financial Performance

The Company’s costs are primarily driven by commodity prices, including the price of iron ore, coal, coke, electricity and natural gas, and inflation or other fluctuations in the prices of key raw materials and other inputs essential to our operations can have a substantial impact on our profitability and overall financial performance. Inflationary pressures on commodity raw material inputs can arise from various factors, including global supply and demand dynamics, geopolitical events, natural disasters, trade policies, and currency exchange rate fluctuations. These factors are often beyond our control and can lead to substantial price increases in raw materials, as well as challenges in managing our supply chain and inventory affecting our ability to secure adequate raw material supplies in a timely and cost-effective manner. Increased costs of raw materials can directly erode our profit margins, making it challenging to maintain competitive pricing in the market.

North American steel pricing is largely dependent on global supply and demand, the level of steel imports into North America, economic conditions in North America, global steelmaking overcapacity, and increased raw material prices. North American steel producers compete with many foreign producers, including those in Europe, China and other Asian countries. Competition from foreign producers is periodically intensified by weakening regional economies of their surrounding countries, and resultant decisions by these foreign producers with respect to export volumes and pricing possibly more influenced by political and economic policy considerations than by prevailing market conditions.

Global steel production decreased 0.1% in calendar 2023 compared to calendar 2022 to 1,849.7 million metric tonnes. China represents approximately 55% of global crude steel production. (source: Worldsteel Association “December 2023 crude steel production and 2023 global crude steel production total” January 25, 2024). According to the Organization for Economic Cooperation and Development global steel market conditions remain challenging, with the latest forecasts suggesting sluggish demand growth. According to the latest available information, global steelmaking capacity remains high at 2,439.7 million metric tonnes, a level that will exceed demand by slightly more than 500 million metric tonnes. This is the equivalent to over 30 times the size of the Canadian steel industry. Additionally a total of 158.3 million metric tonnes of steel investment projects are either currently underway or in the planning stages around the world.

Overall Results

Net Income (Loss)

The Company’s net income for the three month period ended March 31, 2024 was C$28.0 million compared to net loss of C$20.4 million for the three month period ended March 31, 2023, resulting in a C$48.4 million increase of net income. The increase is primarily due to the change in fair value of the warrant liability (C$34.7 million), the increase in foreign exchange gain (C$15.9 million), the change in fair value of the share-based compensation liability (C$11.7 million), and the change in fair value of the earnout liability (C$6.9 million). This was offset, in part, due to the decrease in income from operations (C$18.6 million), for reasons described below in Income from Operations, and the increase in finance costs (C$4.8 million).

The Company’s net income for the year ended March 31, 2024 was C$105.2 million compared to net income

9

of C$298.5 million for the year ended March 31, 2023, resulting in a C$193.3 million decrease of net income. The decrease is primarily due to a decrease in income from operations (C$123.2 million), for reasons described below in Income from Operations, the decrease in foreign exchange gain (C$39.4 million), the change in fair value of the warrant liability (C$35.6 million), the change in fair value of the share-based compensation liability (C$13.9 million), the increase in finance costs (C$7.7 million) and the change in fair value of the earnout liability (C$6.0 million). This was offset, in part, due to the decrease in income tax expense (C$37.9 million).

Income from Operations

The Company’s income from operations for the three month period ended March 31, 2024 was C$3.1 million compared to income from operations of C$21.7 million for the three month period ended March 31, 2023, a decrease of C$18.6 million. The decrease is primarily due to decreased steel shipments, higher purchased coke use and higher natural gas use resulting from the January 20, 2024 incident, as discussed above in Impact on Operations.

The Company’s income from operations for the year ended March 31, 2024 was C$167.3 million compared to income from operations of C$290.5 million for the year ended March 31, 2023, a decrease of C$123.2 million. The decrease is primarily due to increased cost of sales (C$124.8 million) which was driven by higher purchased coke use and higher natural gas use resulting from the January 20, 2024 incident, as discussed above in Impact on Operations, coupled with higher purchase price of coal. In addition, revenue per ton of steel sold decreased by 3.4%. This was offset, in part, increased steel shipment volume of 4.1% and a decrease in pension and post-employment benefit expenses as result of ratifying the collective bargaining agreements (C$53.3 million) in the year ended March 31, 2023.

Non-IFRS Financial Measures

In this MD&A, we use certain non-IFRS measures to evaluate the performance of the Company. These terms do not have any standardized meaning prescribed under IFRS and, therefore, may not be comparable to similar measures presented by other companies. Rather, these measures are provided as additional information to complement those IFRS measures by providing a further understanding of our financial performance from management’s perspective. Accordingly, they should not be considered in isolation nor as a substitute for analysis of our financial information reported in accordance with IFRS. As described below, the terms “EBITDA,” “Adjusted EBITDA,” “Adjusted EBITDA margin,” “Adjusted EBITDA per ton,” “Average Net Sales Realization” (“NSR”) and “Cost Per Ton of Steel Products Sold” are financial measures utilized by the Company in evaluating its financial results that are not defined by IFRS.

EBITDA refers to net income or loss before depreciation of property, plant, equipment and amortization of intangible assets, finance costs, interest on pension and other post-employment benefit obligations and income taxes. Adjusted EBITDA refers to EBITDA before foreign exchange loss (gain), finance income, carbon tax, changes in fair value of warrants, earnout and share-based compensation liabilities, transaction costs and the listing expense incurred in connection with the Merger, past service costs (pension and post-employment benefits), share-based compensation related to the Company’s Omnibus Long Term Incentive Plan and certain inventory write-downs. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA by revenue for the corresponding period. Adjusted EBITDA per ton is calculated by dividing Adjusted EBITDA by tons of steel products sold for the corresponding period. EBITDA and Adjusted EBITDA are not intended to represent cash flow from operations, as defined by IFRS, and should not be considered as alternatives to income from operations or any other measure of performance prescribed by IFRS. EBITDA and Adjusted EBITDA, as defined and used by the Company, may not be comparable to EBITDA and Adjusted EBITDA as defined and used by other companies.

We consider EBITDA and Adjusted EBITDA to be meaningful measures to assess our operating performance in addition to IFRS measures. These measures are included because we believe they can be useful in measuring our operating performance and our ability to expand our business and provide management and investors with additional information for comparison of our operating results across different time periods and to the operating results of other companies. EBITDA and Adjusted EBITDA are also used by analysts and our lenders as measures of our financial performance. In addition, we consider Adjusted EBITDA margin and Adjusted EBITDA per ton, to be useful measures of our operating performance and profitability across different time periods that enhance the comparability of our results.

10

For a reconciliation of Adjusted EBIDTA to its most comparable IFRS financial measures, see “Adjusted EBIDTA” presented in this MD&A. Average Net Sales Realization refers to steel revenue less freight revenue per steel tons shipped. Average Net Sales Realization is included because it allows management and investors to evaluate our selling prices per ton of steel products sold, excluding the geographic impact of freight charges, in order to enhance comparability when comparing our sales performance to that of our competitors. Cost Per Ton of Steel Products Sold refers to cost of steel revenue less freight, depreciation, carbon tax and past service costs for pension and post-employment benefit adjustments (included in cost of steel revenue) per steel tons shipped. Cost Per Ton of Steel Products Sold allows management and investors to evaluate our cost of steel products sold on a per ton basis, excluding certain of the items that we exclude when calculating Adjusted EBITDA, to evaluate our operating performance and to enhance the comparability of our costs over different time periods. We consider each of Average Net Sales Realization and Cost Per Ton of Steel Products Sold to be meaningful measures to assess our operating performance in addition to IFRS measures.

EBITDA, Adjusted EBITDA, Average Net Sales Realization, Cost Per Ton of Steel Products Sold, Adjusted EBITDA margin and Adjusted EBITDA per ton have limitations as analytical tools and should not be considered in isolation from, or as alternatives to, net income, cash flow from operations or other data prepared in accordance with IFRS. Some of these limitations are:

● they do not reflect cash outlays for capital expenditures or contractual commitments;

● they do not reflect changes in, or cash requirements for, working capital;

● they do not reflect the finance costs, or the cash requirements necessary to service interest or principal payments on indebtedness;

● they do not reflect interest on pension and other post-employment benefit obligations;

● they do not reflect income tax expense or the cash necessary to pay income taxes; and

● although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA and Adjusted EBITDA do not reflect cash requirements for such replacements.

In addition, in the case of Adjusted EBITDA, Adjusted EBITDA margin and Adjusted EBITDA per ton:

● they do not reflect certain non-cash items, including share-based compensation charges and the accounting for warrant, earnout and share-based payment liabilities;

● they do not reflect the impact of changes resulting from foreign exchange;

● they do not reflect the impact of carbon tax;

● they do not reflect the impact of certain inventory write-downs;

● they exclude certain non-recurring items, such as transaction costs;

● they do not reflect the impact of past service costs related to pension benefits and post-employment benefits; and

● they do not reflect the impact of other earnings or charges resulting from matters we believe not to be indicative of our ongoing operations.

Because of these limitations EBITDA, Adjusted EBITDA and the related ratios such as Adjusted EBITDA margin and Adjusted EBITDA per ton should not be considered as measures of discretionary cash available to invest in business growth or to reduce indebtedness. In addition, other companies, including other companies in our industry, may calculate these measures differently than we do, limiting their usefulness as comparative measures. We compensate for these limitations by relying primarily on our IFRS results using such measures only as a supplement.

Revenue and steel revenue decreased by 8.4% and 6.7%, respectively, and steel shipment volumes decreased by 21.1% during the three month period ended March 31, 2024 as compared to the three month period ended March 31, 2023. The Company’s average NSR on steel sales per ton shipped was C$1,260 for the three month period ended March 31, 2024 (March 31, 2023 - C$1,066), an increase of 18.2%. The overall decrease in revenue and steel revenue is primarily due to the January 20, 2024 incident, as discussed above in Impact on Operations. This was offset, in part, by an increase in average NSR.

Revenue increased by 0.6%, whereas steel revenue decreased by 0.2%, and steel shipment volumes increased by 4.1% during the year ended March 31, 2024 as compared to the year ended March 31, 2023. The Company’s average NSR on steel sales per ton shipped was C$1,220 for the year ended March 31, 2024 (March 31, 2023 - C$1,273), a decrease of 4.1%. The decrease in steel revenue is mainly due to softening steel prices, offset, in part, by increased steel shipment volumes.

For the three month period ended March 31, 2024, the Company’s cost of steel revenue decreased by 5.3% to C$532.9 million (March 31, 2023 - C$562.5 million) and the cost of steel products sold decreased to C$491.9 million (March 31, 2023 – C$534.0 million). The overall decrease in cost of steel revenue is mainly due to decreased steel production which was offset, in part, by higher purchased coke use and higher natural gas use resulting from the January 20, 2024 incident, as discussed above in Impact on Operations.

For the year ended March 31, 2024, the Company’s cost of steel revenue and cost of steel products sold increased by 4.8% to C$2,263.0 million (March 31, 2023 - C$2,160.2 million) and 5.7% to C$2,123.7 million (March 31, 2023 – C$2,010.1 million), respectively. The overall increase is mainly due to increased steel shipment volumes, the impacts of the January 20, 2024 incident, as discussed above in Impact on

12

Operations, and to an increase in the purchase price of coal.

Non-steel Revenue

The Company’s non-steel revenue for the three month period ended March 31, 2024 was C$4.9 million (March 31, 2023 – C$14.1 million). The decrease of C$9.2 million was mainly due to decreased revenue on braize, ore fines, tar and granulated slag.

The Company’s non-steel revenue for the year ended March 31, 2024 was C$52.2 million (March 31, 2023 – C$46.0 million). The increase of C$6.2 million was mainly due to increased revenue on scrap and ore fines.

As illustrated in the table above, the Company’s administrative and selling expenses for the three month period ended March 31, 2024, were C$32.1 million (March 31, 2023 - C$25.0 million). The increase in administrative and selling expenses of C$7.1 million is mainly due to an increase in personnel expenses (C$3.3 million), provision for uncollectible accounts receivable (C$3.1 million), insurance (C$1.0 million) and software licenses (C$0.5 million). This was offset, in part, by a decrease in professional, consulting, legal and other fees (C$1.6 million).

For the year ended March 31, 2024, the Company’s administrative and selling expenses were C$115.0 million (March 31, 2023 - C$99.3 million). The increase in administrative and selling expenses of C$15.7 million is mainly due to an increase in other administrative and selling (C$7.8 million), personnel expenses (C$5.3 million) and insurance (C$3.8 million). This was offset, in part, by a decrease in professional, consulting, legal and other fees (C$1.9 million).

Finance Costs, Finance Income, Interest on Pension and Other Post-employment Benefit Obligations, and Foreign Exchange Gains and Losses

The Company’s finance costs represent interest cost on the Company’s Revolving Credit Facility and interest cost on the financing arrangement described in the section entitled “Capital Resources - Financial Position and Liquidity” included elsewhere in this MD&A. Finance costs also include the amortization of transaction costs related to the Company’s debt facilities and the accretion of the benefits in respect of the Company’s governmental loan facilities in respect of the interest free loan issued by, and the grant given by the Canadian federal government as well as the low interest rate loan issued from the Ontario provincial government, all of which are discussed below (Financial Resources and Liquidity - Cash Flow Used in Investing Activities) and the unwinding of discounts and changes in the discount rate on the Company’s environmental liabilities.

As illustrated in the table above, the Company’s finance costs for the three month period ended March 31, 2024 were C$9.7 million (March 31, 2023 - C$4.9 million). The increase of C$4.8 million in finance costs is primarily due to the revaluation of the environmental liabilities (C$3.8 million). Furthermore, there was an increase in accretion of government loan benefits (C$0.4 million).

For the year ended March 31, 2024, the Company’s finance costs were C$25.6 million (March 31, 2023 - C$17.9 million). The increase of C$7.7 million in finance costs is primarily due to the revaluation of the environmental liabilities (C$3.8 million), accretion of government loan benefits (C$2.0 million), provincial government loan interest (C$0.6 million), revolving credit facility fees (C$0.4 million) and interest on financing arrangement (C$0.2 million).

The Company’s finance income for the three month period ended March 31, 2024, was C$1.2 million (March 31, 2023 – C$2.9 million). The decrease of C$1.7 million in finance income is primarily due to a reduction in deposits.

The Company’s finance income for the year ended March 31, 2024, was C$10.0 million (March 31, 2023 – C$13.3 million). The decrease of C$3.3 million in finance income is primarily due to a reduction in deposits, offset in part by higher interest rates.

The Company’s interest on pension and other post-employment benefit obligations for the three and twelve month periods ended March 31, 2024 was C$4.9 million and C$19.3 million, respectively, compared to C$4.8 million and C$17.2 million, respectfully, for the three and twelve month periods ended March 31, 2023, due to an increase in discount rates as at March 31, 2023 that was used to determine the 2024 fiscal year pension benefit expense and the impact of the signing of the Collective Bargaining Agreement (“CBA”) on August 1, 2022 that increased the obligations.

The Company’s foreign exchange gain for the three month period ended March 31, 2024 was C$15.8 million (March 31, 2023 – loss of C$0.1 million). The foreign exchange gain for the year ended March 31, 2024 was C$1.7 million (March 31, 2023 –C$41.1 million). These foreign exchange movements reflect the effect of US dollar exchange rate fluctuations on the Company’s Canadian dollar denominated monetary assets and liabilities.

	C$	5.5	C$	(18.6)		C$	88.7	C$	76.1

As illustrated in the table above, the Company’s pension expense for the three month periods ended March 31, 2024 and March 31, 2023 were C$6.5 million and C$6.2 million, respectively, representing an increase of C$0.3 million. The Company’s post-employment benefit expense for the three month periods ended March 31, 2024 and March 31, 2023 were C$3.4 million and C$3.3 million, respectively, representing an increase of C$0.1 million.

For the years ended March 31, 2024 and March 31, 2023, the Company’s pension expense was C$25.4 million and C$73.3 million, respectively, representing a decrease of C$47.9 million. The Company’s post-employment benefit expense for the years ended March 31, 2024 and March 31, 2023 were C$13.7 million and C$16.7 million, respectively, representing a decrease of C$3.0 million. The decrease in pension expense and post-employment benefit expense are due to ratifying the CBA in August 2022 that extended indexation to July 1, 2027 that resulted in a past service cost of C$49.5 million and C$3.8 million, respectively. In addition, the change is also a result of an increase in discount rates as at March 31, 2023 that were used to determine the 2024 fiscal year pension expense and post-employment benefit expense.

As disclosed in Note 3 to the March 31, 2024 consolidated financial statements, all actuarial gains and losses that arise in calculating the present value of the defined benefit pension obligation net of assets and the defined benefit obligation in respect of other post-employment benefits, including the re-measurement components, are recognized immediately in other comprehensive income (loss).

For the three month period ended March 31, 2024, the Company recorded an actuarially determined gain to the accrued defined pension liability and accrued other post-employment benefit obligation in other comprehensive income of C$4.4 million (March 31, 2023 - C$28.1 million), a difference of C$23.7 million. The change is primarily due to a decrease in discount rates.

For the year ended March 31, 2024, the Company recorded actuarially determined loss to the combined accrued defined pension liability and accrued other post-employment benefit obligation in other comprehensive income of C$49.6 million (March 31, 2023 – gain of C$13.8 million), a difference of C$63.4 million, for reasons mentioned above.

Carbon Taxes

On June 28, 2019, the Company became subject to the Federal Greenhouse Gas Pollution Pricing Act (the “Carbon Tax Act”). The Carbon Tax Act was enacted with retroactive effect to January 1, 2019. The Company has chosen to remove the costs associated with the Carbon Tax Act from Adjusted EBITDA to facilitate comparison with the results of its competitors in jurisdictions not subject to the Carbon Tax Act. Since the introduction of the Carbon Tax Act, Ontario’s Emissions Performance Standards (EPS) program was developed to regulate GHG emissions from large industrial facilities by setting emissions limits that are the basis for the compliance obligations of those facilities. The program was developed as an alternative to

15

the federal output-based pricing system (OBPS). The EPS program came into full effect on January 1, 2022 and Algoma is now subject to compliance under the EPS.

For the three month period ended March 31, 2024, total Carbon Tax recognized in cost of sales was C$6.4 million (March 31, 2023 - C$2.9 million). The change is mainly due to an increase in carbon tax per ton. Carbon Tax is primarily a function of the volume of our production.

For the year ended March 31, 2024, total Carbon Tax recognized in cost of sales was C$24.6 million (March 31, 2023 – C$7.2 million). The change in carbon tax is due to an increase in carbon tax per ton and a true-up of the estimated cost in the twelve month period ended March 31, 2024.

Income Taxes

For the three month period ended March 31, 2024, the Company’s deferred income tax recovery and current income tax expense were (C$5.3) million and C$6.3 million, respectively, compared to deferred income tax recovery and current income tax expense of (C$0.8) million and C$6.2 million, respectively, for the three month period ended March 31, 2023.

For the year ended March 31, 2024, the Company’s deferred income tax expense and current income tax expense were C$1.1 million and C$38.6 million, respectively, compared to deferred income tax recovery and current income tax expense of (C$12.0) million and C$89.6 million, respectively, for the year ended March 31, 2023 due to net income before tax of C$144.9 million for the year ended March 31, 2024, compared to income before tax of C$376.1 million for the year ended March 31, 2023.

Share Capital

The authorized share capital of the Company consists of an unlimited number of common shares without par value and an unlimited number of preferred shares without par value issuable in series.

As at March 31, 2024, there were 104,103,072 common shares issued and outstanding, and no preferred shares issued and outstanding.

commensurately. The decrease was driven mainly by a decline in steel shipments of 21% or 120,681 tons, resulting from the January 20, 2024 incident, as discussed above in Impact on Operations. The incident also had the effect of increasing cost per ton of steel products sold, however this impact was partially mitigated by actions taken to reduce costs during the outage, including a temporary partial layoff of unionized workers. In contrast, Adjusted EBITDA / ton increased by C$8 / ton or 10%, driven by an increase in NSR of C$194 / ton or 18%. Stronger steel market conditions, combined with improvements in value-add product mix, including higher volume of plate sales, drove higher NSR. Despite lower shipment volume, the higher NSR produced higher Adjusted EBITDA / ton, and lessened the impact of lower shipment volume and higher cost on Adjusted EBITDA and Adjusted EBITDA margin.

Adjusted EBITDA for the year ended March 31, 2024 decreased by C$139.6 million or 31% from the year ended March 31, 2023, despite an increase in steel shipments of 4% or 82,750 tons. Adjusted EBITDA margin decreased by 5.1% and EBITDA / ton decreased by C$76 / ton or 34% commensurately. The decrease was driven primarily by a decline in NSR of C$53 / ton or 4%, coupled with increased cost per ton of steel products sold in part resulting from the January 20, 2024 incident, as discussed above in Impact on Operations, and in part due to an increase in the purchase price of coal, as discussed above in Steel Revenue and Cost of Sales.

As illustrated in the table above, the generation of cash for the three month period ended March 31, 2024 was C$3.2 million (March 31, 2023 – C$2.7 million). The increase in the generation of cash for the three month period ended March 31, 2024, as compared to the three month period ended March 31, 2023, was C$0.5 million. Cash generated by operating activities increased by C$25.8 million for reasons described below, and the effect of exchange rate changes on cash increased by C$4.0 million. This was offset, in part, by the C$17.0 million increase in cash used in investing activities and the C$12.3 million decrease in cash generated by financing activities, for reasons described below.

For the year ended March 31, 2024, the use of cash was C$149.5 million (March 31, 2023 – C$667.9 million). The decrease in the use of cash for the year ended March 31, 2024, as compared to the year ended March 31, 2023, was C$518.4 million, and is the result of the common shares repurchased and cancelled in the year ended March 31, 2023 (C$553.2 million). More details concerning the various elements of cash generated and used for the periods being reported herein are provided below.

Cash Flow Generated by Operating Activities

For the three month period ended March 31, 2024, the cash generated by operating activities was C$121.2 million (March 31, 2023 – C$95.4 million). The increase in cash generated by operating activities for the three month period ended March 31, 2024 was due primarily to the net change in non-cash working capital (increased by C$31.8 million), for reasons described below.

For the year ended March 31, 2024, the cash generated by operating activities was C$294.9 million (March 31, 2023 – C$177.3 million). The increase in cash generated by operating activities for the year ended March

19

31, 2024 was due primarily to the net change in non-cash working capital (increased by C$211.8 million). This was offset, in part, by the decrease in income from operations (decreased by C$123.2 million), for reasons described above.

Further impacting cash used in operating activities is the net effect from changes in non-cash working capital as presented below:

Cash Flow Used In Investing Activities

For the three month period and year ended March 31, 2024, cash used in investing activities was C$120.4 million and C$490.1 million, respectively (March 31, 2023 – C$103.4 million and C$371.1 million, respectively).

For the three month period ended March 31, 2024, property, plant and equipment were acquired at a total cost of C$120.4 million (March 31, 2023 - C$103.4 million).

For the year ended March 31, 2024, property, plant and equipment were acquired at a total cost of C$490.1 million (March 31, 2023 - C$371.1 million).

For the three month period and year ended March 31, 2024, the Company had additions to property under construction for the EAF project of C$52.9 million and C$257.7 million, respectively (March 31, 2023 – C$68.1 million and C$253.3 million, respectively), excluding the benefits from government loans; in addition, the Company has issued $72.1 million in letters of credit related to equipment fabrication and delivery of which $47.0 million has been released in accordance with the terms. As at March 31, 2024, since inception of the project the Company had additions to property under construction for the EAF project of C$562.8 million, excluding government loans received.

For the three month period and year ended March 31, 2024, the Company had additions to property under construction for the plate mill modernization project of C$0.6 million and C$60.7 million, respectively (March 31, 2023 – C$8.0 million and C$33.1 million, respectively). As at March 31, 2024, since inception of the project the Company had additions for the plate mill modernization project of C$137.4 million, excluding government loans received.

Cash Flow Used In Financing Activities

For the three month period ended March 31, 2024, cash generated by financing activities was C$0.3 million (March 31, 2023 – C$12.6 million). The decrease in cash generated by financing activities of C$12.3 million is primarily due to decreased governmental loans received (C$17.6 million). This was offset, in part, by repayments in excess of funds advanced for bank indebtedness (C$5.4 million).

For the year ended March 31, 2024, cash generated by financing activities was C$44.4 million (March 31, 2023 – cash used C$532.0 million). The increase in cash generated by financing activities of C$576.4 million is primarily due the common shares repurchased and cancelled in the year ended March 31, 2023 (C$553.2 million) and increase in governmental loans received (C$11.5 million) in the year ended March 31, 2024.

Revenue

Fiscal Year Ended March 31, 2024 Compared to Fiscal Year Ended March 31, 2023

The Company’s revenue for the fiscal years ended March 31, 2024 and March 31, 2023 were C$2,795.8 million and C$2,778.5 million, respectively, an increase of C$17.3 million. Refer to the above section Steel Revenue and Cost of Sales for a discussion comparing the year-over-year changes.

Fiscal Year Ended March 31, 2023 Compared to Fiscal Year Ended March 31, 2022

The Company’s revenue for the fiscal years ended March 31, 2023 and March 31, 2022 were C$2,778.5 million and C$3,806.0 million, respectively, a decrease of C$1,027.5 million. Steel revenue decreased by 28.1% and steel shipment volumes decreased by 12.8% during the year ended March 31, 2023, as compared to the year ended March 31, 2022. This decrease was due mainly to weakening market conditions compared to the year ended March 31, 2022.

Income from operations

Fiscal Year Ended March 31, 2024 Compared to Fiscal Year Ended March 31, 2023

The Company’s income from operations for the fiscal years ended March 31, 2024 and March 31, 2023 were C$167.3 million and C$290.5 million, respectively, a decrease of C$123.2 million. Refer to the above section Income from Operations for a discussion comparing the year-over-year changes.

Fiscal Year Ended March 31, 2023 Compared to Fiscal Year Ended March 31, 2022

The Company’s income from operations for the fiscal years ended March 31, 2023 and March 31, 2022 were C$290.5 million and C$1,411.0 million, respectively, a decrease of C$1,120.5 million. This decrease was due mainly to a decrease in steel revenue (C$998.7 million), primarily as a result of weakening market conditions, and an increase in the cost of steel revenue (C$105.6 million) which is mainly due to the replacement of internally produced coke with purchased coke and the increase in the purchase price of key inputs such as coal, natural gas and alloys. Also contributing to the negative variance was the ratification of the collective bargaining agreements, which resulted in increased pension and post-employment benefit expenses (C$53.3 million) compared to the prior year.

Net income

Fiscal Year Ended March 31, 2024 Compared to Fiscal Year Ended March 31, 2023

The Company’s net income for the fiscal years ended March 31, 2024 and March 31, 2023 were C$105.2 million and C$298.5 million, respectively, a decrease of C$193.3 million. Refer to the above section Net Income for a discussion comparing the year-over-year changes.

Fiscal Year Ended March 31, 2023 Compared to Fiscal Year Ended March 31, 2022

The Company’s net income for the fiscal years ended March 31, 2023 and March 31, 2022 were C$298.5 million and C$857.7 million, respectively, a decrease of C$559.2 million. The decrease is mostly driven by lower steel pricing and lower steel shipment volume, higher cost of steel revenue, the replacement of internally produced coke with purchased coke and the increase in the purchase price of key inputs such as coal, natural gas and alloys. Also contributing to the negative variance was the ratification of the collective bargaining agreements, which resulted in increased pension and post-employment benefit expenses (C$53.3 million) compared to the prior year. The comparative decrease in net income is partly offset by listing expense (C$235.6 million) and transaction costs (C$26.5 million) pertaining to the Merger transaction which only impacted the year ended March 31, 2022.

Total assets

Fiscal Year Ended March 31, 2024 Compared to Fiscal Year Ended March 31, 2023

The Company’s total assets for the fiscal years ended March 31, 2024 and March 31, 2023 were C$2,676.0 million and C$2,455.6 million, respectively, an increase of C$220.4 million. This increase was due primarily to the increase in property, plant and equipment (C$325.3 million), primarily as a result of the EAF and PMM projects, and by an increase in inventory (C$85.1 million). This was offset, in part, by a decrease in cash (C$149.5 million), as discussed above in Summary of Cash Flows, and a decrease in accounts receivable (C$44.5 million).

Fiscal Year Ended March 31, 2023 Compared to Fiscal Year Ended March 31, 2022

The Company’s total assets for the fiscal years ended March 31, 2023 and March 31, 2022 were C$2,455.6 million and C$2,693.6 million, respectively, a decrease of C$238.0 million. This decrease was due primarily to the decrease in cash (C$667.9 million) and due to the decrease in trade accounts receivable (C$111.7 million). This was offset, in part, by an increase in property, plant and equipment (C$307.6 million), primarily as a result of the EAF and PMM projects and by an increase in inventory (C$242.7 million).

Total non-current liabilities

Fiscal Year Ended March 31, 2024 Compared to Fiscal Year Ended March 31, 2023

The Company’s total non-current liabilities for the fiscal years ended March 31, 2024 and March 31, 2023 were C$127.4 million and C$110.4 million, respectively, an increase of C$17.0 million. This increase was due to additional claims under the Federal SIF EAF Loan.

Fiscal Year Ended March 31, 2023 Compared to Fiscal Year Ended March 31, 2022

The Company’s total non-current liabilities for the fiscal years ended March 31, 2023 and March 31, 2022 were C$110.4 million and C$85.2 million, respectively, an increase of C$25.2 million. This increase was due to additional claims under the Federal SIF EAF Loan.

Capital Resources - Financial Position and Liquidity

The Company anticipates making approximately C$100 million of capital expenditures annually in order to sustain existing production facilities. Furthermore, supported by its agreements with the federal and provincial governments and using the cash received as a result of the Merger, the Company anticipates making significant capital expenditures relating to its modernization and expansion program over the next five years, including substantial investment in EAF steelmaking.

The below capital sources and future cash flows from operating activities are expected to avail the Company of substantial financial resources to complete its proposed expansion plans. The Company’s business generates significant cash flow and the Company does not anticipate any issues with generating sufficient cash and cash equivalents, both in the short term and the long term to meet its planned growth or

22

to fund development activities.

As at March 31, 2024, the Company had cash of C$97.9 million (March 31, 2023 - C$247.4 million), and had unused availability under its Revolving Credit Facility of C$347.1 million ($256.2 million) after taking into account C$59.1 million ($43.6 million) of outstanding letters of credit. At March 31, 2023, the Company had drawn C$1.9 million ($1.4 million), and there was C$279.2 million ($206.3 million) of unused availability after taking into account C$57.3 million ($42.3 million) of outstanding letters of credit.

The Revolving Credit Facility is governed by a conventional borrowing base calculation comprised of eligible accounts receivable plus eligible inventory plus cash. At March 31, 2024, there was C$0.3 million ($0.2 million) drawn on this facility. The Company is required to maintain a calculated borrowing base. Any shortfall in the borrowing base will trigger a mandatory loan repayment in the amount of the shortfall, subject to certain cure rights including the deposit of cash into an account controlled by the agent. As at March 31, 2024, the Company has complied with these requirements.

On November 30, 2018, the Company secured the following debt financing:

• $250.0 million in the form of a traditional asset-based revolving credit facility, with a maturity date of November 30, 2023 subsequently increased to $300.0 million in May 2023, with maturity date of May 2028 (the “Revolving Credit Facility”). The interest rate is based on Secured Overnight Financing Rate (“SOFR”) plus a credit spread adjustment of 10 basis points plus an applicable margin, which will vary depending on usage;

• a C$60.0 million interest free loan from the Federal Economic Development Agency of the Government of Canada, through the Advanced Manufacturing Fund (the “Federal AMF Loan”). The Company will repay the loan in equal monthly installments beginning on April 1, 2022 with the final installment payable on March 1, 2028; and

• a C$60.0 million low interest loan from the Ministry of Energy, Northern Development and Mines of the Province of Ontario (the “Provincial MENDM Loan”). The Company will repay the loan in monthly blended payments of principal and interest beginning on December 31, 2024 and ending on November 30, 2028.

On March 29, 2019, the Company secured an agreement with the Minister of Industry of the Government of Canada, whereby the Company will receive C$15.0 million in the form of a grant and C$15.0 million in the form of an interest free loan through the Federal SIF. On March 25, 2024, the Company amended the agreement and will repay the interest free loan portion of this funding in equal annual payments beginning on April 30, 2027 and ending on April 30, 2034.

The Revolving Credit Facility, the Federal AMF Loan, the Provincial MENDM Loan and the Federal SIF EAF Loan are expected to service the Company’s principal liquidity needs (to finance working capital, fund capital expenditures and for other general corporate purposes) until the maturity of these facilities.

On November 26, 2021, the Company, together with the Government of Canada, entered into an agreement of which a benefit of up to C$420.0 million would flow to the Company in the form of a loan up to C$200.0 million from the SIF and a loan up to C$220.0 million from the CIB. Under the terms of the Federal SIF EAF Loan, the Company will be reimbursed for certain defined capital expenditures incurred to transition from blast furnace steel production to EAF steel production between March 3, 2021 and June 30, 2025. Annual repayments of the Federal SIF EAF Loan will be scalable based on the Company’s GHG emission performance.

Pursuant to its terms, the CIB credit availability was reduced as a result of share repurchases and dividends paid by the Company, and the loan was undrawn as of March 31, 2024 with limited credit availability remaining. Given that the Company did not expect to draw on the CIB Loan, the parties agreed to terminate the agreement on March 7, 2024.

On December 7, 2023, the Company completed a financing arrangement with the Bank of Montreal for total cash consideration of C$11.7 million. The financing arrangement bears interest at 7.5% with monthly payments of C$0.1 million. At March 31, 2024, current portion totalling C$0.9 million is presented in current portion of other long-term liabilities on the consolidated statements of financial position.

23

On April 5, 2024, the Company’s indirect wholly-owned subsidiary, ASI, issued an aggregate of $350.0 million of 2029 Notes. The 2029 Notes and related guarantees are secured by ASI’s immediate parent company and all of ASI’s subsidiaries on a second-priority liens basis over all assets that are now owned or hereafter acquired by the Company or any of the guarantors, subject to permitted liens and certain other exclusions described in the indenture governing the 2029 Notes. Interest payments commence October 15, 2024 and will be made each April 15 and October 15, thereafter. ASI intends to use the net proceeds from the offering of the 2029 Notes for general corporate purposes, adding strength and flexibility to its balance sheet.

During the three month period and year ended March 31, 2024, the Company declared ordinary dividends to common shareholders in the aggregate amount of C$7.1 million and C$27.9 million, respectively (March 31, 2023 - C$7.1 million and C$30.7 million, respectively), which were paid and recorded as a distribution through retained earnings.

Normal Course Issuer Bid

On March 3, 2022, the Company commenced a normal course issuer bid (the “NCIB”) after receiving regulatory approval from the Toronto Stock Exchange. Pursuant to the NCIB, the Company was authorized to acquire up to a maximum of 7,397,889 of its shares, or 5% of its 147,957,790 issued and outstanding shares as of February 18, 2022, subject to a daily maximum of 16,586 shares. The common shares were available for purchase and cancellation commencing on March 3, 2022 until June 14, 2022 at which time the NCIB was suspended with the launch of the Substantial Issuer Bid (“SIB”). The NCIB resumed after the completion of the SIB and the Company was permitted to acquire shares thereunder until March 2, 2023 under the same terms and conditions.

As at March 31, 2023, the Company purchased and cancelled 3,363,662 common shares at a weighted average book value of C$9.25 ($7.30) per share for a total purchase price of approximately C$37.1 million ($28.6 million). The excess of the purchase price paid over the carrying value of the common shares purchased totalling C$5.7 million, was recognized as an increase to retained earnings.

The Company renewed its NCIB to acquire a maximum of 5,178,394 of its shares, or approximately 5% of its 103,567,884 issued and outstanding shares as of February 28, 2023, subject to a daily maximum of 50,984 shares. The NCIB commenced March 6, 2023 and terminated on March 5, 2024. As at March 31, 2024 and March 31, 2023, the Company has not made any purchases under its renewed NCIB.

Substantial Issuer Bid

On June 21, 2022, the Company commenced a substantial issuer bid in Canada (collectively the “Offer”) to purchase for cancellation up to $400 million of its common shares. The Offer expired on July 27, 2022, and 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 $8.75 and not more than $10.25 per share (in increments of $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 $400 million.

On July 27, 2022, 41,025,641 common shares at a weighted average book value of C$9.11 ($7.33) per

24

share were purchased for cancellation at $9.75 per share, for an aggregate amount of $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 C$127.4 million ($99.3 million) was recognized as a reduction to retained earnings. The Company incurred transaction costs of C$1.1 million related to the SIB which were recorded within capital stock.

Contractual Obligations and Off Balance Sheet Arrangements

The following table presents, at March 31, 2024, the Company’s undiscounted obligations and commitments to make future payments under contracts and contingent commitments. The following figures assume that the March 31, 2024, Canadian/US dollar exchange rate of $1.00 = C$0.7380 remains constant throughout the periods indicated.

Purchase obligations - non-capital, which represent the Company’s most significant contractual obligations across the periods indicated above, are comprised of contracts to purchase the raw materials required to manufacture the Company’s products and therefore contribute directly to the Company’s ability to generate revenue. The Company enters into such contracts on an ongoing basis based on its production requirements to secure favorable raw material pricing and consistency of supply. Most of the Company’s purchase obligations mature in less than one year and are contracted based on the Company’s anticipated production, and the revenue generated from such production is applied to satisfy such purchase obligations. Purchase obligations – capital, represent the Company’s contractual obligations across the periods indicated above for the Electric Arc Furnace and Plate Mill Modernization capital projects.

Off balance sheet arrangements include letters of credit, and operating lease obligations as disclosed above. At March 31, 2024, the Company had C$59.1 million ($43.6 million) (March 31, 2023 - C$57.3 million ($42.3 million)) of outstanding letters of credit.

As discussed above, the Company maintains defined benefit pension plans and other post-employment benefit plans. At March 31, 2024, the Company’s net obligation in respect of its defined benefit pension plans was C$238.0 million (March 31, 2023 - C$184.0 million) and the Company’s obligation in respect of its other post-employment benefits plans was C$229.5 million (March 31, 2023 – C$222.9 million).

The Company’s obligations, commitments and future payments under contract are expected to be financed through cash flow from operations and funds from the Company’s Revolving Credit Facility. Any default in the Company’s ability to meet such commitments and future payments could have a material and adverse effect on the Company.

Related Party Transactions

As at March 31, 2024, there were no transactions, ongoing contractual or other commitments with related parties, except for remuneration of the Company’s key management personnel.

Financial Instruments

The Company’s financial assets and liabilities (financial instruments) include cash, restricted cash, accounts receivable, bank indebtedness, accounts payable and accrued liabilities, warrant liability, earnout liability, long-term governmental loans and other financing arrangements.

25

Financial assets and financial liabilities are recognized when the Company becomes a party to the contractual provisions of the financial instrument or non-financial derivative contract. Financial instruments are disclosed in Notes 29 to the March 31, 2024 consolidated financial statements.

Financial Risk Management

The Company’s activities expose it to a variety of financial risks including credit risk, liquidity risk, interest rate risk and market risk. The Company may use derivative financial instruments to hedge certain of these risk exposures. The use of derivatives is based on established practices and parameters, which are subject to the oversight of the Board of Directors. The Company does not utilize derivative financial instruments for trading or speculative purposes.

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 C$246.7 million (March 31, 2023 - C$291.2 million). At March 31, 2024, there was one customer account greater than 10% of the carrying amount of accounts receivable. At March 31, 2023, there was no customer account greater than 10% of the carrying amount of accounts receivable. As at March 31, 2024, C$6.2 million, or 2.5% (March 31, 2023 - C$2.0 million, or 0.7%), of accounts receivable were more than 90 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 C$3.1 million (March 31, 2023 - C$0.5 million), as disclosed in Note 12 to the March 31, 2024 consolidated financial statements.

The Company may be exposed to certain losses in the event of non-performance by counterparties to derivative financial instruments such as commodity price contracts and foreign exchange contracts. The Company mitigates this risk by entering into transactions with highly rated major financial institutions.

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. There have been no changes to the Company’s objectives and processes for capital management, including the management of long-term debt, as described in Note 5 to the March 31, 2024 consolidated financial statements.

Market risk

Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and commodity prices, will affect the Company’s income or the value of its holdings of financial instruments. 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 to the March 31, 2024 consolidated financial statements, during the three and twelve month periods ended March 31, 2024, the Company was not a party to agreements to hedge the commodity price risk associated with the revenue on

26

the sale of steel however was a party to agreements during the three and twelve month periods ended March 31, 2023. 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.

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 three and twelve month periods ended March 31, 2024 and March 31, 2023, a one percent increase (or decrease) in interest rates would have decreased (or increased) net income (loss) by approximately nil.

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 the March 31, 2024 consolidated financial statements. 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 the March 31, 2024 consolidated financial statements to hedge the commodity price risk associated with the cost of natural gas and the revenue on the sale of steel. At March 31, 2024 and March 31, 2023, the Company had no commodity-based swap contracts.

Critical Accounting Estimates

As disclosed in Note 4 to the March 31, 2024 consolidated financial statements, the preparation of financial statements in conformity 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 dates of the financial statements and the reported amounts of revenue and expenses during the years.

Significant items subject to such estimates and assumptions include the going concern assessment, allowance for doubtful accounts, carrying amount and useful life of property, plant and equipment and intangible assets, defined benefit retirement plans and income tax expense and scientific research and development investment tax credits. Further, Note 3 to the March 31, 2024 consolidated financial statements discloses the basis for determining the fair value of the warrant, earnout and share-based compensation liabilities. Actual results could differ from those estimates.

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.

27

Useful lives of property, plant and equipment and Intangible assets

The Company reviews the estimated useful lives of property, plant and equipment 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. As a result of the Company changing to 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 C$12.5 million. It is expected that there will be a quarterly impact of approximately C$6.1 million to C$6.4 million until December 31, 2029.

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 Cash Generating Unit (“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.

Material Accounting Policies

The Company’s consolidated financial statements have been prepared using consistent accounting policies described in Note 3 to the Company’s annual consolidated financial statements for the years ended March 31, 2024 and 2023.

New IFRS Standards, Amendments and Interpretations adopted as of April 1, 2023 (effective January 1, 2023)

28

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 equal taxable and deductible temporary differences.

Definition of Accounting Estimates

IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors” was amended to introduce the definition of an accounting estimate and includes other amendments to assist entities to distinguish changes in accounting estimates from changes in accounting policies.

Assessments and Changes in Internal Control over Financial Reporting

Management has evaluated the effectiveness of the Company’s internal control over financial reporting (as defined in the applicable U.S. and Canadian securities laws) as of March 31, 2024 and based on that assessment concluded that, as of March 31, 2024, our internal control over financial reporting was effective. Refer to Management’s Report on Internal Control Over Financial Reporting. There have been no changes in our internal control over financial reporting during the quarter or year ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Disclosure Controls and Procedures

Management, including the Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in the applicable U.S. and Canadian securities laws) as of March 31, 2024. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that such disclosure controls and procedures were effective as of March 31, 2024.

Trend Analysis

The Company’s financial performance for the fourth quarter of fiscal year end 2024 (“Q4 2024”) increased from the third quarter of fiscal year end 2024 (“Q3 2024”), primarily due to an increase in Adjusted EBITDA per net ton (“nt”). The following discussion reflects the Company’s trend analysis in chronological order:

Revenue:

• decreased C$7.7 million or 1% from C$941.8 million in Q4 2022 to C$934.1 million in Q1 2023, a result of decreased steel revenue primarily due to lower shipments of steel as shipping volume decreased by 9,693 tons from 547,217 tons in Q4 2022 to 537,524 tons in Q4 2022.

• decreased C$334.9 million or 36% from C$934.1 million in Q1 2023 to C$599.2 million in Q2 2023, a result of decreased steel revenue primarily due to lower selling prices of steel as average NSR per nt decreased by C$366 from C$1,632 per nt in Q1 2023 to C$1,266 per nt in Q2 2023.

• decreased C$31.4 million or 5% from C$599.2 million in Q2 2023 to C$567.8 million in Q3 2023, a result of decreased steel revenue primarily due to lower selling prices of steel as average NSR per nt decreased by C$150 from C$1,266 per nt in Q2 2023 to C$1,116 per nt in Q3 2023.

• increased C$109.6 million or 19% from C$567.8 million in Q3 2023 to C$677.4 million in Q4 2023, a result of increased steel revenue primarily due to increased shipments of steel as shipping volume increased by 113,306 tons from 458,341 tons in Q3 2023 to 571,647 tons in Q4 2023.

• increased C$149.8 million or 22% from C$677.4 million in Q4 2023 to C$827.2 million in Q1 2024, a result of increased steel revenue primarily due to higher selling prices of steel as average NSR

30

per nt increased by C$257 from C$1,066 per nt in Q4 2023 to C$1,323 per nt in Q1 2024.

• decreased C$94.6 million or 11% from C$827.2 million in Q1 2024 to C$732.6 million in Q2 2024, a result of decreased steel revenue primarily due to lower selling prices of steel as average NSR per nt decreased by C$110 from C$1,323 per nt in Q1 2024 to C$1,213 per nt in Q2 2024.

• decreased C$117.2 million or 16% from C$732.6 million in Q2 2024 to C$615.4 million in Q3 2024, a result of decreased steel revenue primarily due to lower selling prices of steel and lower shipment volumes.

• increased C$5.2 million or 1% from C$615.4 million in Q3 2024 to C$620.6 million in Q4 2024, a result of increased steel revenue primarily due to higher selling prices of steel, offset, in part, by lower shipment volumes.

Net income (loss):

• of C$301.4 million in Q1 2023 increased compared to C$242.9 million in Q4 2022 mainly due to the changes in fair value of warrant liability (C$51.6 million) and changes in fair value of share-based compensation liability (C$12.3 million).

• of C$87.2 million in Q2 2023 decreased compared to C$301.4 million in Q1 2023 primarily due to decreased revenue of C$334.9 million, a result of lower selling prices of steel with a lower decrease in cost of sales of C$55.2 million. In addition, pension and post-employment benefit expenses increased as a result of ratifying the collective bargaining agreements (C$53.3 million). This was offset in part by lower income tax expense of C$80.0 million due to lower income before income taxes.

• of (C$69.8) million in Q3 2023 decreased compared to C$87.2 million in Q2 2023 primarily due to decreased revenue of C$31.4 million, a result of lower selling prices of steel, and due to an increase in cost of sales of C$42.4 million. In addition, the decrease was due in part to foreign exchange loss increasing as a result of fluctuating exchange rates (C$50.7 million) and the changes in fair value of warrant liability (C$41.5 million).

• of (C$20.4) million in Q4 2023 increased compared to (C$69.8) million in Q3 2023 primarily due to increased revenue (C$109.6 million), a result of increased shipping volume. This was offset, in part, by an increase in cost of sales (C$18.9 million), the changes in fair value of the warrant liability (C$13.0 million), the fair value of the share-based payment compensation liability (C$7.1 million) and the fair value of earnout liability (C$3.7 million).

• of C$130.9 million in Q1 2024 increased compared to (C$20.4) million in Q4 2023 primarily due to increased revenue (C$149.8 million), a result of higher selling prices of steel. This was offset, in part, by an increase in cost of sales (C$8.8 million) due to higher purchase price of key inputs such as ore pellets.

• of C$31.1 million in Q2 2024 decreased compared to C$130.9 million in Q1 2024 mostly due to decreased revenue (C$94.6 million), a result of lower selling prices of steel, and by an increase in cost of sales (C$25.3 million), due mainly to higher purchased coke use and lower production volume. This was offset, in part, by lower income taxes (C$27.4 million) due to lower income from operations.

• of (C$84.8) million in Q3 2024 decreased compared to C$31.1 million in Q2 2024 mostly due to decreased revenue (C$117.2 million), a result of lower selling prices of steel and shipment volumes, the changes in fair value of the warrant liability (C$20.1 million), the fair value of the share-based payment compensation liability (C$12.6 million) and the fair value of earnout liability (C$6.9 million). This was offset, in part, by lower cost of sales (C$41.0 million) primarily due to lower shipment volumes.

• of C$28.0 million in Q4 2024 increased compared to (C$84.8) million in Q3 2024 mostly due to decreased cost of sales (C$38.4 million), a result of lower shipment volumes, foreign exchange gain (C$30.5 million), the changes in fair value of the warrant liability (C$35.7 million), the fair value of the share-based payment compensation liability (C$16.1 million) and the fair value of earnout liability (C$9.6 million). This was offset, in part, by increased income tax expense (C$13.5 million).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Algoma Steel Group Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Algoma Steel Group Inc. and subsidiaries (the “Company”) as at March 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as at and for the year ended March 31, 2024, of the Company and our report dated June 20, 2024 expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Algoma Steel Group Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of Algoma Steel Group Inc. and subsidiaries (the “Company”) as at March 31, 2024 and 2023, the related consolidated statements of net income, comprehensive income, changes in shareholders’ equity, and cash flows for each of the two years in the period ended March 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as at March 31, 2024 and 2023, and its financial performance and its cash flows for each of the two years in the period ended March 31, 2024, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as at March 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated June 20, 2024, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition – Refer to Notes 3 and 6 of the financial statements.

Critical Audit Matter Description

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 of the steelmaking processes and related freight revenue. The Company’s performance obligations in respect of its steel contracts are satisfied upon loading the products onto the truck, railcar or vessel that will deliver the products to the customer, at which time the products are deemed to be transferred and the customer obtains title to, and control of, such products.

Revenue is a critical audit matter due to the significant audit effort required in performing audit procedures related to the company’s revenue recognition and the significance of the account balance.

How the Critical Audit Matter was Addressed in the Audit

Our audit procedures related to revenue recognition included the following, among others:

● Evaluated the design and operating effectiveness of the Company’s controls over revenue recognition;

● On a sample basis, evaluated the recognition of revenue, by obtaining and inspecting invoices, bill of ladings/ shipping documents and cash receipts;

● On a sample basis, evaluated the recognition of revenue recorded for new customers in the year by obtaining evidence for the validity of the third party customer;

● On a sample basis, evaluated whether there was an appropriate rationale and evidence for the validity of manual journal entries to revenue.

Notes to the Consolidated Financial Statements

Tabular amounts expressed in millions of Canadian dollars except for share and per share information

2. BASIS OF PRESENTATION (continued)

For reporting purposes, the consolidated financial statements are presented in millions of Canadian dollars (“$C”). The assets and liabilities are translated into the reporting currency using exchange rates prevailing at the end of each reporting period. Income and expense items are translated at average exchange rates for the reporting period. Exchange differences arising are recognized in other comprehensive income and accumulated in equity under the heading ‘Foreign exchange on translation to presentation currency’.

Equity transactions, as disclosed in Note 26, are translated at the historical exchange rates. The resulting net translation adjustment has been recorded in other comprehensive income for the year.

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 items that are measured in terms of historical cost are not re-translated. Exchange gains or losses arising from translations of foreign currency monetary assets, liabilities and transactions are recorded in foreign exchange loss (gain) in the consolidated statements of net income.

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 of a financial asset (or a portion thereof) constitutes a derecognition event. Write-off occurs when the Company has no reasonable expectations of recovering the contractual cash flows associated with a financial asset.

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))

14

ALGOMA STEEL GROUP INC.

Notes to the Consolidated Financial Statements

Tabular amounts expressed in millions of Canadian dollars except for share and per share information

3. MATERIAL ACCOUNTING POLICIES (continued)

Financial assets are classified and subsequently measured based on the business model in which they are managed and their cash flow characteristics. Financial assets are measured at amortized cost if they meet both of the following conditions and are not designated as FVTP(L):

● 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, or designated as FVTP(L) upon initial recognition, and is remeasured at its fair value at each subsequent reporting period, with any changes recorded through profit or loss. Other financial liabilities are subsequently measured at amortised cost using the effective interest method.

Impairment of financial assets carried at amortized cost

The Company utilizes an ‘expected credit loss’ (“ECL”) model, as required by IFRS 9 – Financial Instruments. Accounts receivable are subject to lifetime ECL which is measured as the difference in the present value of the contractual cash flows that are due under the contract, and the cash flows that are expected to be received.

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 is later recovered, the recovery is recognized in the consolidated statements of net income.

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

15

ALGOMA STEEL GROUP INC.

Notes to the Consolidated Financial Statements

Tabular amounts expressed in millions of Canadian dollars except for share and per share information

3. MATERIAL ACCOUNTING POLICIES (continued)

liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability (for example, interest rate and yield curves observable at commonly quoted intervals, forward pricing curves used to value currency and commodity contracts), or inputs that are derived principally from or corroborated by observable market data or other means. Level 3 inputs are unobservable (supported by little or no market activity). The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. There were no transfers among Levels 1, 2 and 3 during the years ended March 31, 2024 and March 31, 2023. The Company’s policy is to recognize transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer.

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 bearing. 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. Recoveries of accounts receivables previously provided for in the allowance for doubtful accounts are deducted from administrative and selling expenses in the consolidated statements of net income.

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

16

ALGOMA STEEL GROUP INC.

Notes to the Consolidated Financial Statements

Tabular amounts expressed in millions of Canadian dollars except for share and per share information

3. MATERIAL ACCOUNTING POLICIES (continued)

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. 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.

The Company, as a lessee, recognizes a right-of-use asset and lease liability at commencement of the lease at the present value of the future lease payments using the interest rate implicit in the lease (if readily determinable) or the Company’s incremental rate of borrowing. Subsequent to initial measurement, the asset is depreciated using the straight-line method from the commencement date to the earlier of the end of its useful file or the end of the lease term. The lease liability is measured at amortized cost using the effective interest rate method. Lease related finance charges are recorded in finance costs in the consolidated statement of net income.

The Company has elected not to recognize right-of-use assets and lease liabilities for short-term leases defined as leases with a lease term of 12 months or less and low-value assets. These types of leases are recorded in the consolidated statement of net income as incurred.

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

3. MATERIAL ACCOUNTING POLICIES (continued)

transfer those amounts recognized in other comprehensive income (loss) to a separate reserve within equity. Net-interest is calculated by applying the discount rate to the net defined benefit liability. Defined benefit and other post-employment benefit costs are split into three categories:

● 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

18

Notes to the Consolidated Financial Statements

Tabular amounts expressed in millions of Canadian dollars except for share and per share information

3. MATERIAL ACCOUNTING POLICIES (continued)

material, environmental liabilities are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

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 of the steelmaking processes and related freight revenue.

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 when the performance obligation is satisfied by transferring the promised good to a customer. A good is considered transferred when the customer obtains control, which is defined as the ability to direct the use of and obtain substantially all of the remaining benefits of an asset. The Company’s performance obligations in respect of its steel contracts are satisfied upon loading the products onto the truck, railcar or vessel that will deliver the products to the customer (known as free on board or “FOB” shipping), at which time the products are deemed to be transferred and the customer obtains title to, and control of, such products. Upon the fulfillment of these criteria, revenue and costs associated with such are included in the consolidated statements of net income.

Freight and other transportation costs billed to customers are recorded gross within revenue and cost of goods sold. Non-steel revenue primarily pertains to the sale of various by-products such as kish, ore fines, mill scale, scrap rolls and high sulfur iron. The Company’s performance obligations in respect of its sales of by-products are satisfied upon loading of the applicable by-products on an FOB shipping basis, at which time such by-products are deemed to be transferred and the customer obtains title to, and control of, such 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

3. MATERIAL ACCOUNTING POLICIES (continued)

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.

3. MATERIAL ACCOUNTING POLICIES (continued)

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 equal taxable and deductible temporary differences.

3. MATERIAL ACCOUNTING POLICIES (continued)

Definition of Accounting Estimates

IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors” was amended to introduce the definition of an accounting estimate and includes other amendments to assist entities to distinguish changes in accounting estimates from changes in accounting policies.

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 to clarify its requirements for the presentation of liabilities in the statement of financial position. The limited scope amendment affected only the presentation of liabilities in the statement of financial position and not the amount or timing of its recognition. The amendment clarified that the classification of liabilities as current or non-current is based on rights that are in existence at the end of the reporting period and specified that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement of a liability. It also introduced a definition of ‘settlement’ to make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services. On October 31, 2022, the IASB issued Non-Current Liabilities with Covenants (Amendments to IAS 1). These amendments specify that covenants to be complied with after the reporting date do not affect the classification of debt as current or non-current at the reporting date. The amendment is effective for annual reporting periods beginning on or after January 1, 2024. Earlier application is permitted. The application of these amendments are not expected to have a significant impact on the consolidated statements of financial position or on the Company’s financial reporting.

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:

4. CRITICAL ESTIMATES AND JUDGEMENTS (continued)

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.

Useful lives of property, plant and equipment

The Company reviews the estimated useful lives of property, plant and equipment at the end of each annual reporting period, and whenever events or circumstances indicate a change in useful life. 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.

19. DERIVATIVE FINANCIAL INSTRUMENTS

The Company is party to an International Swaps and Derivatives Association, Inc. (ISDA) 2002 master agreement with an investment and financial services company to hedge the commodity price risk associated with various commodities. As at March 31, 2024 and March 31, 2023, the Company had no outstanding hedging agreements. The commodity contracts to hedge the NYMEX price of the hot rolled coil price of steel are derivatives, which are designated as cash flow hedges for which hedge effectiveness is measured for the duration of the agreements and therefore carried at fair value through other comprehensive income or loss. As of March 31, 2024 and March 31, 2023, the company had no outstanding steel derivative contracts and as a result, the fair value liability was nil.

The cumulative amount of gains and losses on cash flow hedging instruments assessed as effective are presented in the cash flow hedge reserve through other comprehensive income or loss and is recognized in profit or loss only when the hedged transaction impacts the profit or loss, or is included directly in the initial cost or other carrying amount of the hedged non-financial items (basis adjustment).

During the year ended March 31, 2023, the realized income resulting from the steel hedge of $9.3 million, was subsequently reclassified from Other Comprehensive Income and recognized in revenue.

The movements in the cash flow hedge reserve for the period as a component of accumulated other comprehensive income is as follows:

	March 31,  2024		March 31,  2023
Opening balance	$	-	$	24.7
Income arising on changes in fair value of cash flow hedges, net of tax expense of nil and $7.8 million, respectively		-		(34.0	)

20. 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 employees in Canada joining the Company after January 1, 2003. As part of Old Steelco Inc.’s contract negotiations with its locals which concluded on July 31, 2010, the locals and Old Steelco Inc. agreed to include in this plan all unionized employees hired subsequent to August 1, 2010 and to offer to all the current employees the option to move to the Defined Contribution Pension Plan. The plan was revised by Old Steelco Inc. during the year ended March 31, 2011; these revisions went into effect March 1, 2011. Based on this revision, the Company is obligated to provide a base contribution of 5% of salary and also match employee contributions to a maximum of 2%, depending on years of service for non-unionized employees. Additionally, the Company is obligated to provide a contribution for unionized employees per qualified hour worked of $2.85.

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 defined benefit pension plans that are closed to new entrants and cover all employees in Canada not covered under the Defined Contribution Pension Plan. The benefits are based on years of service and average earnings for a defined period prior to retirement.

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”).

These defined benefit pension plans are registered under the Pension Benefits Act (Ontario), and are legally separated from the Company. The Pension Benefits Act (Ontario) is a regulatory framework that has jurisdiction over the administration and funding of defined benefit pension plans. Within this framework, the Company has fiduciary responsibility over the administration of the defined benefit pension plans, including the development and oversight of the investment policy for pension funds and the selection and oversight of pension fund investment managers.

The defined benefit pension plans expose the Company to various risks such as: investment risk, interest rate risk, foreign currency risk, price risk, credit risk and liquidity risk.

The most recent actuarial valuations of plan assets and the present value of the defined benefit obligation were carried out at April 1, 2023 for salaried, hourly and wrap plans.

20. PENSION BENEFITS (continued)

The major categories of plan assets were as follows:

As at	March 31, 2024	March 31, 2023
Cash and cash equivalents	1%	1%
Equity instruments	55%	33%
Debt instruments	41%	39%
Other	3%	27%
	100%	100%

Cash flow information

The Company is required to make contributions equal to current service cost. 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, 2024		March 31, 2023
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).

25. COMMITMENTS AND CONTINGENCIES

Property, plant and equipment

In the normal course of business operations the Company has certain commitments for capital expenditures related to the maintenance and acquisition of property, plant and equipment.

Key inputs to production

The Company requires large quantities of iron ore, coal, oxygen, electricity and natural gas in order to satisfy the demands of the steel manufacturing operation. The Company makes most of its purchases of these principal raw materials at negotiated prices under annual and multi-year agreements. 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.

Normal Course Issuer Bid

On March 3, 2022, the Company commenced a normal course issuer bid (the “2022 NCIB”) after receiving regulatory approval from the Toronto Stock Exchange. Pursuant to the NCIB, the Company was authorized to acquire up to a maximum of 7,397,889 of its shares, or 5% of its 147,957,790 issued and outstanding shares as of February 18, 2022, subject to a daily maximum of 16,586 shares. The common shares were available for purchase and cancellation commencing on March 3,

26. CAPITAL STOCK (continued)

2022 until June 14, 2022 at which time the NCIB was suspended with the launch of the Substantial Issuer Bid (“SIB”). The NCIB resumed after the completion of the SIB and the Company was permitted to acquire its shares until March 2, 2023 under the same terms and conditions.

As at March 31, 2023, the Company purchased and cancelled 3,364,262 common shares at a weighted average book value of $9.25 (US $7.30) per share for a total purchase price of approximately $37.1 million (US $28.6 million). The excess of the purchase price paid over the carrying value of the common shares purchased totalling $5.9 million, was recognized as an increase to retained earnings.

The Company renewed its NCIB to acquire a maximum of 5,178,394 of its shares, or approximately 5% of its 103,567,884 issued and outstanding shares as of February 28, 2023, subject to a daily maximum of 50,984 shares. The NCIB commenced March 6, 2023 and terminated on March 5, 2024. The Company has not made any purchases under its renewed NCIB.

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.

(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”). Further, on March 31, 2023 the Board of Directors granted 457,935 and 404,211 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, 2024 (“FY2024 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 common shares outstanding, as the Replacement LTIP Awards are fully vested and exercisable for a nominal price. For the year ended March 31, 2024, 2,925,499 (March 31, 2023 - 3,100,535) weighted average

Fair value of financial instruments

The fair value of cash, restricted cash, accounts receivable, accounts payable and accrued liabilities approximates their carrying value due to the short-term nature of these instruments. 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 carrying value due to prevailing interest rates and the risk characteristics of the instrument.

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 forward prices of NYMEX hot rolled coil steel based on the applicable settlement dates of the outstanding swap contracts.

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.

Financial risk management

The Company’s activities expose it to a variety of financial risks including credit risk, liquidity risk, interest rate risk and market risk. The Company may use derivative financial instruments to hedge certain of these risk exposures. The use of derivatives is based on established practices and parameters, which are subject to the oversight of the Board of Directors. The Company does not utilize derivative financial instruments for trading or speculative purposes.

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.

29. FINANCIAL INSTRUMENTS (continued)

The maximum credit exposure at March 31, 2024 is the carrying amount of accounts receivable of $246.7 million (March 31, 2023 - $291.2 million). At March 31, 2024, there was one customer account greater than 10% of the carrying amount of accounts receivable. At March 31, 2023, there was no customer account greater than 10% of the carrying amount of accounts receivable. As at March 31, 2024, $6.2 million, or 2.5% (March 31, 2023 - $2.0 million, or 0.7%), of accounts receivable were more than 90 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 by counterparties to derivative financial instruments such as commodity price contracts and foreign exchange contracts. The Company mitigates this risk by entering into transactions with highly rated major financial institutions.

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 Company’s objectives and processes for capital management, including the management of long-term debt, are described in Note 5.

The following table discloses the Company’s contractually agreed (undiscounted) cash flows payable under financial liabilities, as at March 31, 2024:

	Carrying Amount		Contractual Cash Flows			Year 1			Year 2			Years 3 to 5			Greater than 5 Years

Market risk

Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and commodity prices, will affect the Company’s income or the value of its holdings of financial instruments. 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, 2024			March 31, 2023
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 have decreased (or increased) income (loss) from operations (March 31, 2023 - $0.2 million).

29. FINANCIAL INSTRUMENTS (continued)

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 increase (or decrease) in interest rates would have decreased (or increased) net income (loss) by approximately nil.

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.

30. WARRANT LIABILITY

As at March 31, 2024, 24,179,000 Warrants remain outstanding with an estimated fair value of US $1.37 per Warrant based on the market price of the Warrants, for which the Company recognized a liability of $44.9 million (US $33.1 million) (March 31, 2023 - $57.3 million; US $42.3 million). For the year ended March 31, 2024, a gain of $12.1 million (March 31, 2023 – $47.7 million) on change in the fair value of the warrant liability is presented in the consolidated statements of net income. The Warrants will expire on the fifth anniversary of the merger transaction which was completed on October 19, 2021.

31. EARNOUT LIABILITY

As at March 31, 2024, 1,196,157 earnout rights remain outstanding with an estimated fair value of US $8.49 per unit based on the market price of the Company’s common shares, for which an earnout liability of $13.8 million (US $10.2 million) (March 31, 2023 - $16.8 million; US $12.4 million) was recognized on the consolidated statements of financial position. For the year ended March 31, 2024, earnout rights were settled for cash totalling $2.5 million (March 31, 2023 – nil). Loss on change in the fair value of the earnout liability for the year ended March 31, 2024 of $0.1 million is presented in the consolidated statements of net income (March 31, 2023 – gain of $5.9 million).

34. SHARE-BASED COMPENSATION (continued)

Deferred share units

Under the terms of the Omnibus Plan, DSUs may be issued to members of the Board of Directors as may be designated by the Board of Directors from time-to-time in satisfaction of all or a portion of Director fees. The number of DSUs to be issued in satisfaction of a payment of Director fees shall be equal to the amount of the Director fees divided by the given day volume weighted average price of the Company’s common shares preceding the grant date. DSUs are equity-settled share-based payments measured at fair value at the date of grant and expensed immediately as the underlying services have been rendered. The grant date fair value is approximated by the price of the Company’s common shares on the date of grant. DSUs do not have an exercise price and become exercisable for one common share of the Company upon the retirement of the Director, or in the event of incapacity.

For the year ended March 31, 2024, the Company recorded a share-based payment compensation expense of $2.2 million (March 31, 2023 - $1.7 million) in administrative and selling expense on the consolidated statements of net income and contributed deficit on the consolidated statements of financial position.

Dividend equivalents and other adjustments		12,511			4,441
Vested and settled		(70,920	)		-
Ending balance		344,768			215,628

Restricted share units and performance share units

Under the terms of the Omnibus Plan, RSUs and PSUs may be issued to employees of the Company as may be designed by the Board of Directors in order to retain and motivate employees. RSUs and PSUs are equity-settled share-based payments measured at fair value at the date of grant and expensed over the vesting period. The grant date fair value takes into account any non-vesting conditions. The subsequent recognition of the grant date fair value over the vesting period involves the Company’s estimation of the RSUs and PSUs that will eventually vest and adjusts for the likelihood of achieving service conditions and performance conditions. RSUs and PSUs do not have an exercise price and become exercisable for one common share of the Company on the vesting date. Holders of RSUs and PSUs are also entitled to dividend equivalents when dividends are declared to common shareholders. The price of the Company’s common shares on the grant date is used to approximate the grant date fair value of each unit of RSUs and PSUs.

FY2023 Plan

On May 17, 2022, 141,203 RSUs and 556,348 PSUs were granted to certain employees of the Company, with a grant date fair value of US $9.40 per award based on the market price of the Company’s common shares. The RSUs and PSUs vest on March 15, 2024 upon the achievement of service and performance conditions. The total grant date fair value determined is recognized on a straight-line basis over the vesting period and is subject to true-ups at each period end to reflect the likelihood of achieving certain performance conditions.

Basis of Presentation

2. BASIS OF PRESENTATION

Statement of compliance

These consolidated financial statements have been prepared in accordance with International Financial Reporting Standard (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

These consolidated financial statements have been approved by the Board of Directors, and authorized for issuance on June 19, 2024.

Functional and presentation currency

The Company and its subsidiaries’ functional currency is the United States dollar (“US dollar”). The US dollar is the currency of the primary economic environment in which the Company and its subsidiaries operate.

For reporting purposes, the consolidated financial statements are presented in millions of Canadian dollars (“$C”). The assets and liabilities are translated into the reporting currency using exchange rates prevailing at the end of each reporting period. Income and expense items are translated at average exchange rates for the reporting period. Exchange differences arising are recognized in other comprehensive income and accumulated in equity under the heading ‘Foreign exchange on translation to presentation currency’.

Equity transactions, as disclosed in Note 26, are translated at the historical exchange rates. The resulting net translation adjustment has been recorded in other comprehensive income for the year.

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 items that are measured in terms of historical cost are not re-translated. Exchange gains or losses arising from translations of foreign currency monetary assets, liabilities and transactions are recorded in foreign exchange loss (gain) in the consolidated statements of net income.

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 of a financial asset (or a portion thereof) constitutes a derecognition event. Write-off occurs when the Company has no reasonable expectations of recovering the contractual cash flows associated with a financial asset.

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 their cash flow characteristics. Financial assets are measured at amortized cost if they meet both of the following conditions and are not designated as FVTP(L):

● 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, or designated as FVTP(L) upon initial recognition, and is remeasured at its fair value at each subsequent reporting period, with any changes recorded through profit or loss. Other financial liabilities are subsequently measured at amortised cost using the effective interest method.

Impairment of financial assets carried at amortized cost

The Company utilizes an ‘expected credit loss’ (“ECL”) model, as required by IFRS 9 – Financial Instruments. Accounts receivable are subject to lifetime ECL which is measured as the difference in the present value of the contractual cash flows that are due under the contract, and the cash flows that are expected to be received.

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 is later recovered, the recovery is recognized in the consolidated statements of net income.

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 and yield curves observable at commonly quoted intervals, forward pricing curves used to value currency and commodity contracts), or inputs that are derived principally from or corroborated by observable market data or other means. Level 3 inputs are unobservable (supported by little or no market activity). The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. There were no transfers among Levels 1, 2 and 3 during the years ended March 31, 2024 and March 31, 2023. The Company’s policy is to recognize transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer.

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 bearing. 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. Recoveries of accounts receivables previously provided for in the allowance for doubtful accounts are deducted from administrative and selling expenses in the consolidated statements of net income.

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. 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.

The Company, as a lessee, recognizes a right-of-use asset and lease liability at commencement of the lease at the present value of the future lease payments using the interest rate implicit in the lease (if readily determinable) or the Company’s incremental rate of borrowing. Subsequent to initial measurement, the asset is depreciated using the straight-line method from the commencement date to the earlier of the end of its useful file or the end of the lease term. The lease liability is measured at amortized cost using the effective interest rate method. Lease related finance charges are recorded in finance costs in the consolidated statement of net income.

The Company has elected not to recognize right-of-use assets and lease liabilities for short-term leases defined as leases with a lease term of 12 months or less and low-value assets. These types of leases are recorded in the consolidated statement of net income as incurred.

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 is calculated by applying the discount rate to the net defined benefit liability. Defined benefit and other post-employment benefit costs are split into three categories:

● 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 rate that reflects current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

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 of the steelmaking processes and related freight revenue.

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 when the performance obligation is satisfied by transferring the promised good to a customer. A good is considered transferred when the customer obtains control, which is defined as the ability to direct the use of and obtain substantially all of the remaining benefits of an asset. The Company’s performance obligations in respect of its steel contracts are satisfied upon loading the products onto the truck, railcar or vessel that will deliver the products to the customer (known as free on board or “FOB” shipping), at which time the products are deemed to be transferred and the customer obtains title to, and control of, such products. Upon the fulfillment of these criteria, revenue and costs associated with such are included in the consolidated statements of net income.

Freight and other transportation costs billed to customers are recorded gross within revenue and cost of goods sold. Non-steel revenue primarily pertains to the sale of various by-products such as kish, ore fines, mill scale, scrap rolls and high sulfur iron. The Company’s performance obligations in respect of its sales of by-products are satisfied upon loading of the applicable by-products on an FOB shipping basis, at which time such by-products are deemed to be transferred and the customer obtains title to, and control of, such 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 equal taxable and deductible temporary differences.

Definition of Accounting Estimates

IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors” was amended to introduce the definition of an accounting estimate and includes other amendments to assist entities to distinguish changes in accounting estimates from changes in accounting policies.

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 to clarify its requirements for the presentation of liabilities in the statement of financial position. The limited scope amendment affected only the presentation of liabilities in the statement of financial position and not the amount or timing of its recognition. The amendment clarified that the classification of liabilities as current or non-current is based on rights that are in existence at the end of the reporting period and specified that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement of a liability. It also introduced a definition of ‘settlement’ to make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services. On October 31, 2022, the IASB issued Non-Current Liabilities with Covenants (Amendments to IAS 1). These amendments specify that covenants to be complied with after the reporting date do not affect the classification of debt as current or non-current at the reporting date. The amendment is effective for annual reporting periods beginning on or after January 1, 2024. Earlier application is permitted. The application of these amendments are not expected to have a significant impact on the consolidated statements of financial position or on the Company’s financial reporting.

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.

Useful lives of property, plant and equipment

The Company reviews the estimated useful lives of property, plant and equipment at the end of each annual reporting period, and whenever events or circumstances indicate a change in useful life. 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.

Depreciation of property, plant and equipment

Depreciation of property, plant and equipment for the year ended March 31, 2024 was $118.8 million (March 31, 2023 - $95.2 million). Depreciation included in inventories at March 31, 2024, amounted to $13.9 million (March 31, 2023 - $9.7 million).

Derivative Financial Instruments

19. DERIVATIVE FINANCIAL INSTRUMENTS

The Company is party to an International Swaps and Derivatives Association, Inc. (ISDA) 2002 master agreement with an investment and financial services company to hedge the commodity price risk associated with various commodities. As at March 31, 2024 and March 31, 2023, the Company had no outstanding hedging agreements. The commodity contracts to hedge the NYMEX price of the hot rolled coil price of steel are derivatives, which are designated as cash flow hedges for which hedge effectiveness is measured for the duration of the agreements and therefore carried at fair value through other comprehensive income or loss. As of March 31, 2024 and March 31, 2023, the company had no outstanding steel derivative contracts and as a result, the fair value liability was nil.

The cumulative amount of gains and losses on cash flow hedging instruments assessed as effective are presented in the cash flow hedge reserve through other comprehensive income or loss and is recognized in profit or loss only when the hedged transaction impacts the profit or loss, or is included directly in the initial cost or other carrying amount of the hedged non-financial items (basis adjustment).

During the year ended March 31, 2023, the realized income resulting from the steel hedge of $9.3 million, was subsequently reclassified from Other Comprehensive Income and recognized in revenue.

The movements in the cash flow hedge reserve for the period as a component of accumulated other comprehensive income is as follows:

Pension Benefits

20. 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 employees in Canada joining the Company after January 1, 2003. As part of Old Steelco Inc.’s contract negotiations with its locals which concluded on July 31, 2010, the locals and Old Steelco Inc. agreed to include in this plan all unionized employees hired subsequent to August 1, 2010 and to offer to all the current employees the option to move to the Defined Contribution Pension Plan. The plan was revised by Old Steelco Inc. during the year ended March 31, 2011; these revisions went into effect March 1, 2011. Based on this revision, the Company is obligated to provide a base contribution of 5% of salary and also match employee contributions to a maximum of 2%, depending on years of service for non-unionized employees. Additionally, the Company is obligated to provide a contribution for unionized employees per qualified hour worked of $2.85.

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 defined benefit pension plans that are closed to new entrants and cover all employees in Canada not covered under the Defined Contribution Pension Plan. The benefits are based on years of service and average earnings for a defined period prior to retirement.

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”).

These defined benefit pension plans are registered under the Pension Benefits Act (Ontario), and are legally separated from the Company. The Pension Benefits Act (Ontario) is a regulatory framework that has jurisdiction over the administration and funding of defined benefit pension plans. Within this framework, the Company has fiduciary responsibility over the administration of the defined benefit pension plans, including the development and oversight of the investment policy for pension funds and the selection and oversight of pension fund investment managers.

The defined benefit pension plans expose the Company to various risks such as: investment risk, interest rate risk, foreign currency risk, price risk, credit risk and liquidity risk.

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).

Commitments and Contingencies

25. COMMITMENTS AND CONTINGENCIES

Property, plant and equipment

In the normal course of business operations the Company has certain commitments for capital expenditures related to the maintenance and acquisition of property, plant and equipment.

Key inputs to production

The Company requires large quantities of iron ore, coal, oxygen, electricity and natural gas in order to satisfy the demands of the steel manufacturing operation. The Company makes most of its purchases of these principal raw materials at negotiated prices under annual and multi-year agreements. 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.

Normal Course Issuer Bid

On March 3, 2022, the Company commenced a normal course issuer bid (the “2022 NCIB”) after receiving regulatory approval from the Toronto Stock Exchange. Pursuant to the NCIB, the Company was authorized to acquire up to a maximum of 7,397,889 of its shares, or 5% of its 147,957,790 issued and outstanding shares as of February 18, 2022, subject to a daily maximum of 16,586 shares. The common shares were available for purchase and cancellation commencing on March 3,

2022 until June 14, 2022 at which time the NCIB was suspended with the launch of the Substantial Issuer Bid (“SIB”). The NCIB resumed after the completion of the SIB and the Company was permitted to acquire its shares until March 2, 2023 under the same terms and conditions.

As at March 31, 2023, the Company purchased and cancelled 3,364,262 common shares at a weighted average book value of $9.25 (US $7.30) per share for a total purchase price of approximately $37.1 million (US $28.6 million). The excess of the purchase price paid over the carrying value of the common shares purchased totalling $5.9 million, was recognized as an increase to retained earnings.

The Company renewed its NCIB to acquire a maximum of 5,178,394 of its shares, or approximately 5% of its 103,567,884 issued and outstanding shares as of February 28, 2023, subject to a daily maximum of 50,984 shares. The NCIB commenced March 6, 2023 and terminated on March 5, 2024. The Company has not made any purchases under its renewed NCIB.

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.

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”). Further, on March 31, 2023 the Board of Directors granted 457,935 and 404,211 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, 2024 (“FY2024 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 common shares outstanding, as the Replacement LTIP Awards are fully vested and exercisable for a nominal price. For the year ended March 31, 2024, 2,925,499 (March 31, 2023 - 3,100,535) 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.

29. FINANCIAL INSTRUMENTS

Fair value of financial instruments

The fair value of cash, restricted cash, accounts receivable, accounts payable and accrued liabilities approximates their carrying value due to the short-term nature of these instruments. 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 carrying value due to prevailing interest rates and the risk characteristics of the instrument.

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 forward prices of NYMEX hot rolled coil steel based on the applicable settlement dates of the outstanding swap contracts.

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’s financial assets and liabilities are classified and measured as follows:

Financial risk management

The Company’s activities expose it to a variety of financial risks including credit risk, liquidity risk, interest rate risk and market risk. The Company may use derivative financial instruments to hedge certain of these risk exposures. The use of derivatives is based on established practices and parameters, which are subject to the oversight of the Board of Directors. The Company does not utilize derivative financial instruments for trading or speculative purposes.

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 $246.7 million (March 31, 2023 - $291.2 million). At March 31, 2024, there was one customer account greater than 10% of the carrying amount of accounts receivable. At March 31, 2023, there was no customer account greater than 10% of the carrying amount of accounts receivable. As at March 31, 2024, $6.2 million, or 2.5% (March 31, 2023 - $2.0 million, or 0.7%), of accounts receivable were more than 90 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 by counterparties to derivative financial instruments such as commodity price contracts and foreign exchange contracts. The Company mitigates this risk by entering into transactions with highly rated major financial institutions.

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 Company’s objectives and processes for capital management, including the management of long-term debt, are described in Note 5.

The following table discloses the Company’s contractually agreed (undiscounted) cash flows payable under financial liabilities, as at March 31, 2024:

	Carrying Amount		Contractual Cash Flows			Year 1			Year 2			Years 3 to 5			Greater than 5 Years

Market risk

Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and commodity prices, will affect the Company’s income or the value of its holdings of financial instruments. 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, 2024			March 31, 2023
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 have decreased (or increased) income (loss) from operations (March 31, 2023 - $0.2 million).

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 increase (or decrease) in interest rates would have decreased (or increased) net income (loss) by approximately nil.

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.

Long-term incentive plan

On October 19, 2021, the Company approved an Omnibus Equity Incentive Plan (“Omnibus Plan”) that would allow the Company to grant various awards to its employees. Under the terms of the Omnibus Plan, the maximum number of common shares that may be awarded is 8.8 million common shares. The awards issuable under the Plan consists of Restricted Share Units (“RSU”), DSUs, Performance Share Units (“PSU”) and stock options.

Deferred share units

Under the terms of the Omnibus Plan, DSUs may be issued to members of the Board of Directors as may be designated by the Board of Directors from time-to-time in satisfaction of all or a portion of Director fees. The number of DSUs to be issued in satisfaction of a payment of Director fees shall be equal to the amount of the Director fees divided by the given day volume weighted average price of the Company’s common shares preceding the grant date. DSUs are equity-settled share-based payments measured at fair value at the date of grant and expensed immediately as the underlying services have been rendered. The grant date fair value is approximated by the price of the Company’s common shares on the date of grant. DSUs do not have an exercise price and become exercisable for one common share of the Company upon the retirement of the Director, or in the event of incapacity.

For the year ended March 31, 2024, the Company recorded a share-based payment compensation expense of $2.2 million (March 31, 2023 - $1.7 million) in administrative and selling expense on the consolidated statements of net income and contributed deficit on the consolidated statements of financial position.

Restricted share units and performance share units

Under the terms of the Omnibus Plan, RSUs and PSUs may be issued to employees of the Company as may be designed by the Board of Directors in order to retain and motivate employees. RSUs and PSUs are equity-settled share-based payments measured at fair value at the date of grant and expensed over the vesting period. The grant date fair value takes into account any non-vesting conditions. The subsequent recognition of the grant date fair value over the vesting period involves the Company’s estimation of the RSUs and PSUs that will eventually vest and adjusts for the likelihood of achieving service conditions and performance conditions. RSUs and PSUs do not have an exercise price and become exercisable for one common share of the Company on the vesting date. Holders of RSUs and PSUs are also entitled to dividend equivalents when dividends are declared to common shareholders. The price of the Company’s common shares on the grant date is used to approximate the grant date fair value of each unit of RSUs and PSUs.

FY2023 Plan

On May 17, 2022, 141,203 RSUs and 556,348 PSUs were granted to certain employees of the Company, with a grant date fair value of US $9.40 per award based on the market price of the Company’s common shares. The RSUs and PSUs vest on March 15, 2024 upon the achievement of service and performance conditions. The total grant date fair value determined is recognized on a straight-line basis over the vesting period and is subject to true-ups at each period end to reflect the likelihood of achieving certain performance conditions.

FY2024 Plan

On March 31, 2023 the Board of Directors approved a grant of 457,935 and 404,211 units of RSUs and PSUs, respectively, to various employees of the Company under the Omnibus Plan for the fiscal year ended March 31, 2024, with a grant date fair value of US $7.62 per award based on the market price of the Company’s common shares. The RSUs and PSUs vest on March 31, 2026 upon the achievement of service and performance conditions. The total grant date fair value determined is recognized on a straight-line basis over the vesting period and is subject to true-ups at each period end to reflect the likelihood of achieving certain performance conditions

Foreign exchange transactions

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 items that are measured in terms of historical cost are not re-translated. Exchange gains or losses arising from translations of foreign currency monetary assets, liabilities and transactions are recorded in foreign exchange loss (gain) in the consolidated statements of net income.

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 of a financial asset (or a portion thereof) constitutes a derecognition event. Write-off occurs when the Company has no reasonable expectations of recovering the contractual cash flows associated with a financial asset.

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 their cash flow characteristics. Financial assets are measured at amortized cost if they meet both of the following conditions and are not designated as FVTP(L):

● 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, or designated as FVTP(L) upon initial recognition, and is remeasured at its fair value at each subsequent reporting period, with any changes recorded through profit or loss. Other financial liabilities are subsequently measured at amortised cost using the effective interest method.

Impairment of financial assets carried at amortized cost

The Company utilizes an ‘expected credit loss’ (“ECL”) model, as required by IFRS 9 – Financial Instruments. Accounts receivable are subject to lifetime ECL which is measured as the difference in the present value of the contractual cash flows that are due under the contract, and the cash flows that are expected to be received.

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 is later recovered, the recovery is recognized in the consolidated statements of net income.

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 and yield curves observable at commonly quoted intervals, forward pricing curves used to value currency and commodity contracts), or inputs that are derived principally from or corroborated by observable market data or other means. Level 3 inputs are unobservable (supported by little or no market activity). The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. There were no transfers among Levels 1, 2 and 3 during the years ended March 31, 2024 and March 31, 2023. The Company’s policy is to recognize transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer.

The Company reclassifies financial assets only when its business model for managing those assets changes. Financial liabilities are not reclassified.

Accounts receivable

Accounts receivable

Accounts receivable are recognized initially at transaction price and are non-interest bearing. 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. Recoveries of accounts receivables previously provided for in the allowance for doubtful accounts are deducted from administrative and selling expenses in the consolidated statements of net income.

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. 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.

The Company, as a lessee, recognizes a right-of-use asset and lease liability at commencement of the lease at the present value of the future lease payments using the interest rate implicit in the lease (if readily determinable) or the Company’s incremental rate of borrowing. Subsequent to initial measurement, the asset is depreciated using the straight-line method from the commencement date to the earlier of the end of its useful file or the end of the lease term. The lease liability is measured at amortized cost using the effective interest rate method. Lease related finance charges are recorded in finance costs in the consolidated statement of net income.

The Company has elected not to recognize right-of-use assets and lease liabilities for short-term leases defined as leases with a lease term of 12 months or less and low-value assets. These types of leases are recorded in the consolidated statement of net income as incurred.

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 is calculated by applying the discount rate to the net defined benefit liability. Defined benefit and other post-employment benefit costs are split into three categories:

● 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 rate that reflects current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

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 of the steelmaking processes and related freight revenue.

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 when the performance obligation is satisfied by transferring the promised good to a customer. A good is considered transferred when the customer obtains control, which is defined as the ability to direct the use of and obtain substantially all of the remaining benefits of an asset. The Company’s performance obligations in respect of its steel contracts are satisfied upon loading the products onto the truck, railcar or vessel that will deliver the products to the customer (known as free on board or “FOB” shipping), at which time the products are deemed to be transferred and the customer obtains title to, and control of, such products. Upon the fulfillment of these criteria, revenue and costs associated with such are included in the consolidated statements of net income.

Freight and other transportation costs billed to customers are recorded gross within revenue and cost of goods sold. Non-steel revenue primarily pertains to the sale of various by-products such as kish, ore fines, mill scale, scrap rolls and high sulfur iron. The Company’s performance obligations in respect of its sales of by-products are satisfied upon loading of the applicable by-products on an FOB shipping basis, at which time such by-products are deemed to be transferred and the customer obtains title to, and control of, such 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.

New IFRS Standards, Amendments and Interpretations adopted as of April 1, 2023 (effective January 1, 2023)

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 equal taxable and deductible temporary differences.

Definition of Accounting Estimates

IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors” was amended to introduce the definition of an accounting estimate and includes other amendments to assist entities to distinguish changes in accounting estimates from changes in accounting policies.

Standards and Interpretations issued and not yet adopted

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 to clarify its requirements for the presentation of liabilities in the statement of financial position. The limited scope amendment affected only the presentation of liabilities in the statement of financial position and not the amount or timing of its recognition. The amendment clarified that the classification of liabilities as current or non-current is based on rights that are in existence at the end of the reporting period and specified that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement of a liability. It also introduced a definition of ‘settlement’ to make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services. On October 31, 2022, the IASB issued Non-Current Liabilities with Covenants (Amendments to IAS 1). These amendments specify that covenants to be complied with after the reporting date do not affect the classification of debt as current or non-current at the reporting date. The amendment is effective for annual reporting periods beginning on or after January 1, 2024. Earlier application is permitted. The application of these amendments are not expected to have a significant impact on the consolidated statements of financial position or on the Company’s financial reporting.

Summary of Computation of Basic and Diluted Net Income (Loss) Per Common Share

The following table sets forth the computation of basic and diluted net income per common share:

Year ended,	March 31, 2024			March 31, 2023
(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).
