**PART II**

**ITEM 15.**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **CONTROLS AND PROCEDURES**

***Disclosure Controls and Procedures***

At the end of the period covered by this report, an evaluation of the effectiveness of the design and operation of the Company's "disclosure controls and procedures" (as such term is defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act) was carried out by the Company's principal executive officer (the "**CEO**") and principal financial officer (the "**CFO**"). There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Based upon their evaluation, the Company's CEO and CFO concluded that, during the first three quarters of the fiscal year ended December 31, 2024, there were material weaknesses in the Company's disclosure controls and procedures.

Management identified the following material weaknesses:

i. An ineffective control environment resulting from the combination of an insufficient number of trained financial reporting and accounting personnel with the appropriate skills and knowledge regarding the design, implementation, and operation of internal control over financial reporting.

ii. Management had not designed or implemented a control monitoring process necessary to identify control weaknesses and remediations in a timely manner necessary to ensure the reliability of its internal control over financial reporting.

iii. Control deficiencies in procurement and payment resulting from a lack of formal processes and inconsistent receiving processes at the Company's refinery project.

During each of the third and fourth fiscal quarters of the fiscal year ended December 31, 2024, the Company improved its disclosure controls and procedures such that, by December 31, 2024, the Company's CEO and CFO no longer identified material weaknesses. However, while recognizing the improvements that had been made to the disclosure controls and procedures, the Company's CEO and CFO concluded that significant deficiencies in the disclosure controls and procedures remained as at December 31, 2024.

As a consequence, the disclosure controls and procedures were not effective to ensure that (i) information required to be disclosed in reports that the Company files or submits to regulatory authorities is recorded, processed, summarized and reported within the time periods specified by regulation, and (ii) is accumulated and communicated to management, including the Company's CEO and CFO, to allow timely decisions regarding required disclosure.

***Management Report on Internal Control Over Financial Reporting***

Management is responsible for establishing and maintaining adequate internal control over financial reporting ("**ICFR**") (as such term is defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) and has designed such internal control over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and preparation of financial statements for external purposes in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

In designing and evaluating the Company's ICFR, the Company's management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its reasonable judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management conducted an evaluation of the effectiveness of the Company's ICFR as of December 31, 2024. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based upon their evaluation, the Company's CEO and CFO have concluded that, during the first three quarters of the fiscal year ended December 31, 2024 (from January 1, 2024 through September 30, 2024), there were material weaknesses in the internal control over financial reporting. Similar to the material weaknesses outlined jn *Disclosure Controls and Procedures*, outlined above, material weaknesses in the internal control over financial reporting included (i) an ineffective control environment resulting from the combination of an insufficient number of trained financial reporting and accounting personnel, (ii) lack of a control monitoring process necessary to identify weaknesses and (iii) deficiencies in the procurement, payment and receiving processes resulting from a lack of formal processes at the Company's refinery project. During the second half of the fiscal year ended December 31, 2024 (July 1, 2024 through December 31, 2024), the Company improved its internal control over financial reporting such that, by December 31, 2024, the Company's CEO and CFO no longer identified material weaknesses. However, while recognizing the improvements that had been made to the internal control over financial reporting, the Company's CEO and CFO concluded that significant deficiencies in the internal control over financial reporting remained as at the end of the year on December 31, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1

------

As a consequence, the Company's internal control over financial reporting was not effective as of December 31, 2024.

***Attestation Report of Independent Auditor***

In accordance with the JOBS Act enacted on April 5, 2012, the Company qualifies as an "emerging growth company," which entitles the Company to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not EGCs. Specifically, the JOBS Act defers the requirement to have the Company's independent auditor assess the Company's internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act. As such, the Company is exempted from the requirement to include an auditor attestation report in this Annual Report for so long as the Company remains an EGC, which may be for as long as five years following its initial registration in the United States.

***Changes in Internal Control over Financial Reporting***

The Company's CEO and CFO are responsible for designing internal control over financial reporting or causing it to be designed under their supervision to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS.

Although substantial progress has been made strengthening internal control over financing reporting during the fourth quarter of fiscal 2024, management acknowledges that it has identified certain significant deficiencies in ICFR as at the end of the fiscal year on December 31, 2024. These deficiencies are not uncommon for an early-stage, pre-revenue company with a small finance team and limited resources. Like many small companies at a similar stage of development, the Company has not yet implemented the full suite of systems, processes, and personnel typically found in more mature organizations. Management continues to assess and enhance its internal control as the company scales and transitions toward commercial operations.

The Company's CEO and CFO identified the following areas where material improvements were made during the fourth quarter of fiscal 2024.

● Control Environment

---

| | |
|:---|:---|
| o | The Company increased the number of trained financial reporting and accounting personnel with the appropriate skills and knowledge regarding the design, implementation, and operation of internal controls over financing reporting. |

---

● Control Monitoring Process

---

| | |
|:---|:---|
| o | The Company implemented a control monitoring process to identify weaknesses in its ICFR. |

---

● Procurement, Payment and Receiving Processes

---

| | |
|:---|:---|
| o | The Company improved reporting and receiving processes to ensure adherence to the Company's policies at the Company's refinery project. |

---

The Company's primary assets, including its hydrometallurgical refinery in Ontario, Canada and its cobalt exploration properties in Idaho, USA, are currently on care and maintenance. One or both of these assets are expected to become more active during fiscal 2025 and 2026, at which time, the Company intends to further enhance and improve its ICFR appropriately for such additional activities. Specific areas of focus are expected to be: (i) the control environment, including IT infrastructure and processes, and internal audit function; (ii) the control monitoring process; (iii) the payroll process; (iv) the property, plant and equipment process; and (v) the procurement, payment and receiving processes.

<br> **ELECTRA BATTERY MATERIALS CORPORATION**<br> **CONSOLIDATED FINANCIAL STATEMENTS**<br> **FOR THE YEARS ENDED DECEMBER 31, 2024, 2023 AND 2022**<br>**(EXPRESSED IN THOUSANDS OF CANADIAN DOLLARS)**<br>

**ELECTRA BATTERY MATERIALS CORPORATION** 

CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2024, 2023 AND 2022

*(expressed in thousands of Canadian dollars)*

**Report of Management**'**s Accountability**

The accompanying audited consolidated financial statements of Electra Battery Materials Corporation were prepared by management in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. Management acknowledges responsibility for significant accounting judgements and estimates and for the choice of accounting principles and methods that are appropriate to the Company's circumstances.

During the first 3 quarters of the fiscal year 2024, management identified material weaknesses in the internal controls over financial reporting and disclosure controls and procedures. During each of the third and fourth fiscal quarters of the fiscal year ended December 31, 2024, the Company improved its internal controls over financial reporting such that, as at December 31, 2024, management no longer identified material weaknesses. However, while recognizing the improvements, management concluded that significant deficiencies in the internal controls over financial reporting and disclosure controls and procedures remained at December 31, 2024. As a consequence, the Company had ineffective controls activities related to the design of process level and financial statement close controls.

Management has implemented appropriate processes to support management representations that it has exercised reasonable diligence that the consolidated financial statements fairly present, in all material respects, the financial condition, financial performance and cash flows of the Company, as of the date of and for the periods presented in the consolidated financial statements.

The Board of Directors is responsible for reviewing and approving the audited consolidated financial statements to ensure the Company fulfills its financial reporting responsibilities. The Board of Directors carries out this responsibility principally through its Audit Committee.

The Audit Committee is appointed by the Board of Directors and all of its members are non-management Directors. The Audit Committee reviews the consolidated financial statements, management's discussion and analysis and the external auditors' report; examines the fees and expenses for audit services; and considers the engagement or reappointment of the external auditors. The Audit Committee reports its findings to the Board of Directors for its consideration when approving the consolidated financial statements for issuance. MNP LLP, the external auditors, have full and free access to the Audit Committee.

CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2024, 2023 AND 2022

*(expressed in thousands of Canadian dollars)*

![mnp.jpg](mnp.jpg)

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

------

To the Board of Directors of Electra Battery Materials Corporation

**Opinion on the Consolidated Financial Statements**

We have audited the accompanying consolidated statements of financial position of Electra Battery Materials Corporation (the "Company") as at December 31, 2024 and 2023 and the related consolidated statements of loss and other comprehensive loss, shareholders' equity, and cash flows for each of the years in the two-year period ended December 31, 2024, and the related notes (collectively referred to as the "consolidated financial statements").

In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as at December 31, 2024 and 2023, and the results of its consolidated operations and its consolidated cash flows for each of the years in the two-year period ended December 31, 2024, in conformity with IFRS® Accounting Standards as issued by the International Accounting Standards Board.

We have also audited the effects of the adjustments to retrospectively apply the change in segment composition as described in Note 22 and the effect of the share consolidation as described in Note 17 to the 2022 consolidated financial statements. In our opinion, such adjustments are appropriate and have been properly applied. We were not engaged to audit, review, or apply any procedures to the 2022 consolidated financial statements of the Company other than with respect to the adjustments and, accordingly, we do not express an opinion or any other form of assurance on the 2022 consolidated financial statements taken as a whole.

**Material Uncertainty Related to Going Concern**

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 of the consolidated financial statements, the Company has suffered recurring losses and negative cash flows from operations which raises substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

**Change in Accounting Principle**

As discussed in Note 4 to the consolidated financial statements, the Company has changed its method of accounting for the classification of convertible notes as current or non-current as of January 1, 2023 due to the adoption of amendments to IAS 1 – Non- current liabilities with covenants.

**Basis for Opinion**

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Report of Independent Registered Public Accounting Firm**

To the Shareholders and Board of Directors of Electra Battery Materials Corporation

***Opinion on the Consolidated Financial Statements***

We have audited, before the effects of the adjustments to retrospectively apply the change in segment composition as described in Note 22 and the effects of the share consolidation as described in Note 17, the consolidated statements of income (loss) and other comprehensive income (loss), cash flows and shareholders' equity for the year ended December 31, 2022, and the related notes (collectively, the consolidated financial statements) of Electra Battery Materials Corporation (the Company). The 2022 consolidated financial statements before the effects of the adjustments described in Note 22 and Note 17 are not presented herein. In our opinion, the consolidated financial statements, before the effects of the adjustments to retrospectively apply the change in segment composition described in Note 22 and the effects of the share consolidation described in Note 17, present fairly, in all material respects the financial performance and cash flows of the Company for the year ended December 31, 2022, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We were not engaged to audit, review, or apply any procedures to the adjustments to retrospectively apply the change in segment composition described in Note 22 or the effect of the share consolidation described in Note 17 and, accordingly, we do not express an opinion or any other form of assurance about whether such adjustments are appropriate and have been properly applied. Those adjustments were audited by other auditors.

*Basis for Opinion*

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

**ELECTRA BATTERY MATERIALS CORPORATION** 

CONSOLIDATED STATEMENTS OF CASH FLOWS

FOR THE YEARS ENDED DECEMBER 31, 2024, 2023 AND 2022

*(expressed in thousands of Canadian dollars)*

***1.*** **Significant Nature of Operations**

Electra Battery Materials Corporation (the "Company", "Electra") was incorporated on *July 13, 2011* under the Business Corporations Act of British Columbia (the "Act"). On *September 4, 2018,* the Company filed a Certificate of Continuance into Canada and adopted Articles of Continuance as a Federal Company under the Canada Business Corporations Act (the "CBCA"). On *December 6, 2021,* the Company changed its corporate name from First Cobalt Corp. to Electra Battery Materials Corporation. The Company is in the business of producing battery materials for the electric vehicle supply chain. The Company is focused on building a supply of cobalt, nickel and recycled battery materials.

Electra is a public company which is listed on the Toronto Venture Stock Exchange (TSX-V) (under the symbol ELBM). On *April 27, 2022,* the Company began trading on the NASDAQ (under the symbol ELBM). The Company's registered office is Suite *2400,* Bay-Adelaide Centre, *333* Bay Street, Toronto, Ontario, *M5H 2T6* and the corporate head office is located at *133* Richmond Street W, Suite *602,* Toronto, Ontario, *M5H 2L3.*

The Company is focused on building a North American integrated battery materials facility for the electric vehicle supply chain. The Company is in the process of constructing its expanded hydrometallurgical cobalt refinery (the "Refinery"), assessing the various optimizations and modular growth scenarios for a recycled battery material (known as black mass) program, and exploring and developing its mineral properties.

**Going Concern Basis of Accounting**

The accompanying audited consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business for the foreseeable future, and, as such, the audited consolidated financial statements do *not* include any adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.

The Company has recurring net operating losses and negative cash flows from operations. As of *December 31, 2024, 2023* and *2022,* the Company had an accumulated deficit of $274,892, $245,445 and $180,779, respectively, though, the Company was in compliance with all required covenants as of *December 31, 2024.* The Company's recurring losses from operations and negative cash flows raise substantial doubt about the Company's ability to continue as a going concern. The global economy, including the financial and credit markets, has recently experienced extreme volatility and disruptions, including increasing inflation rates, rising interest rates, foreign currency impacts, declines in consumer confidence, and declines in economic growth. Additionally, the Company suspended construction of the Refinery in *2023* due to lack of sufficient funding in the wake of supply chain disruptions. All these factors point to uncertainty about economic stability, and the severity and duration of these conditions on our business cannot be predicted, and the Company cannot assure that it will remain in compliance with the financial covenants contained within its credit facilities. Management monitors recent developments in relation to global tariffs and does *not* anticipate any material impacts on the financial position of the Company.

In order to continue its operations, the Company must achieve profitable operations and/or obtain additional equity or debt financing. Until the Company achieves profitability, management plans to fund its operations and capital expenditures with cash on hand, borrowings, and issuance of capital stock. Until the Company generates revenue at a level to support its cost structure, the Company expects to continue to incur substantial operating losses and net cash outflows from operating activities.

**ELECTRA BATTERY MATERIALS CORPORATION**

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

The Company is actively pursuing various alternatives including government grants and loans, strategic partnerships, equity and debt financing to increase its liquidity and capital resources. During *2024,* a government loan from Federal Economic Development Agency for Northern Ontario ("FedNor') was received in the amount of $5,267.

On *August 19, 2024,* the Company was awarded US$20,000 in funding by the U.S. Department of Defense ("DoD") for the construction of the Refinery funded on a reimbursement basis. The award was made pursuant to Title III of the Defense Production Act (DPA) to expand domestic production capability. On *November 25, 2024,* the Company completed a private placement of US$1,000 as detailed in Note *13.* On *November 27, 2024,* the Company issued secured convertible notes in the principal amount of US$4,000 as detailed in Note *11.* Although the Company has historically been successful in obtaining financing in the past, there can be *no* assurances that the Company will be able to obtain adequate financing in the future. These audited consolidated financial statements do *not* include the adjustments to the amounts and classifications of assets and liabilities that would be necessary should the Company be unable to continue as a going concern. These adjustments *may* be material.

***2.*** **Material Accounting Policies and Basis of Preparation**

***Basis of Presentation and Statement of Compliance***

These consolidated financial statements, including comparatives, have been prepared in accordance with IFRS® Accounting Standards as issued by the International Accounting Standard Board. These financial statements have been prepared on a historical cost basis, except for certain financial instruments, which are classified as fair value through profit or loss ("FVTPL"). All amounts on the consolidated financial statements are presented in thousands of Canadian dollars, except share and per share amounts, and otherwise noted.

Certain comparatives in *2023* have been restated to conform with current accounting presentation.

***Functional Currency***

The functional currency of the Company and its controlled entities are measured using the principal currency of the primary economic environment in which each entity operates. The functional currency of the Company and its subsidiaries is Canadian dollars, except for Cobalt One Limited which has a functional currency of Australian Dollars and United States entities which has a functional currency of US Dollars for *2024* and *2023.*

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the date of the transaction. Foreign currency monetary items are retranslated at the period-end exchange rate. Non-monetary items measured at historical cost continue to be carried at the exchange rate at the date of the transaction. Non-monetary items measured at fair value are reported at the exchange rate at the date when fair values were determined.

Foreign exchange differences on monetary items are recognized in profit or loss in the period in which they arise except for:

● Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the costs of assets as they are regarded as an adjustment to interest costs on those currency borrowings.

● Foreign exchange gains or losses arising from a monetary item receivable for or payable to a foreign operation, the settlement of which is neither planned nor likely to occur in the foreseeable future and which in substance is considered to form part of the net investment in the foreign operation are recognized in other comprehensive income or loss.

**ELECTRA BATTERY MATERIALS CORPORATION**

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

The assets and liabilities of entities with a functional currency that differs from the presentation currency are translated to the presentation currency as follows:

● Assets and liabilities are translated at the closing rate at the end of the financial reporting period;

● Income, expenses, and cash flows are translated at average exchange rates (unless the average is *not* a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case, income and expenses are translated at the rate on the dates of the transactions);

● Equity transactions are translated using the exchange rate at the date of the transaction; and

● All resulting exchange differences are recognized as a separate component of equity as accumulated other comprehensive income.

During *2023,* the Company's considered primary and secondary indicators in determining functional currency including the currency in which funds from financing activities were generated, the Company re-evaluated the functional currency of its US subsidiaries and determined that a change in their functional currency from Canadian dollars to US Dollars was appropriate. The Company translated its US subsidiaries' assets and liabilities into the new functional currency of US dollars at the opening spot rate for the year and recorded a translation adjustment from *January 1, 2023* onwards to reflect the impact of translating the Company's US dollar assets and liabilities to the presentation currency. The change in functional currency for these subsidiaries has been applied prospectively.

***Basis of Consolidation***

These consolidated financial statements include the accounts of the Company and its controlled entities. Control is achieved when the Company has the power to govern the financial operating policies of an entity to obtain benefits from its activities. Subsidiaries are fully consolidated from the date on which control is transferred to the Company until the date on which control ceases.

---

All inter-company transactions, balances, income and expenses are eliminated in full upon consolidation.

***Cash and Cash equivalents***

Cash and cash equivalents consist of cash on hand, deposits in banks and highly liquid investments with an original maturity of *three* months or less.

***Restricted cash***

Restricted cash consists of escrow funds for settlement with vendors held by the Company's legal counsel with term of less than *one* year. Long-term restricted cash relates to amounts on deposit as financial assurance for the refinery closure plan.

***Marketable Securities***

Marketable securities represent shares held in a publicly traded company. Marketable securities held by the Company are held for trading purposes and are classified as financial asset measured at FVTPL. At each reporting date, the Company marks-to-market the value of the marketable securities based on quoted market prices; therefore, these financial assets are classified as Level *1* on the fair value hierarchy.

Any profit or loss arising from the sale of these securities, or the revaluation at reporting dates, is recorded to the consolidated statement of income (loss) and other comprehensive income (loss). As the marketable securities are held for trading purposes and *not* as part of a strategic investment, they are expected to be liquidated within a *twelve*-month period and are classified as a current asset on the statement of financial position.

***Financial instruments***

Cash and cash equivalents, restricted cash, receivables, accounts payable and accrued liabilities, and debt securities issued are initially recognized when they are originated. All other financial assets and financial liabilities are initially recognized when the Company becomes a party to the contractual provisions of the instrument.

**ELECTRA BATTERY MATERIALS CORPORATION**

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

The Company recognizes all financial assets initially at fair value and classifies them into *one* of the following measurement categories: FVTPL, fair value through other comprehensive income or amortized cost, as appropriate.

Financial liabilities are initially recognized at fair value and classified as either FVTPL or amortized cost, as appropriate.

Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership.

At each reporting date, the Company assesses whether there is objective evidence that a financial asset has been impaired.

The Company had made the following classification of its financial instruments:

---

| | |
|:---|:---|
| **Financial assets or liabilities, accrued interest and lease liability** | **Measurement Category** |
| Cash and cash equivalents | Amortized Cost |
| Restricted cash | Amortized Cost |
| Receivables | Amortized Cost |
| Marketable securities | FVTPL |
| Account payable and accrued liabilities | Amortized Cost |
| Convertible notes payable | FVTPL |
| Government loan payable | Amortized Cost |
| Warrants | FVTPL |
| Royalty | Amortized Cost |

---

Financial instruments measured at fair value are classified into *one* of the *three* levels in the fair value hierarchy according to the relative reliability of the inputs used to estimate the fair values. The *three* levels of the fair value hierarchy are:

Level *1* – Unadjusted quoted prices in active markets for identical assets or liabilities;

Level *2* – Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly;

Level *3* – Inputs that are *not* based on observable market data.

***Exploration and Evaluation Assets***

The acquisition costs of mineral property interests have been capitalized as exploration and evaluation assets within the Company's financial statements. Subsequent exploration and evaluation costs are expensed until the property to which they relate has demonstrated technical feasibility and commercial viability, after which costs are capitalized.

The acquisition costs include the cash consideration paid and the fair market value of any shares issued for mineral property interests being acquired or optioned pursuant to the terms of relevant agreements. When a partial sale of a mineral property occurs, if control is lost the asset is derecognized and there is a resultant gain or loss recorded to profit and loss in the period the transaction takes place. When all of the interest in a property is sold, subject only to any retained royalty interests which *may* exist, the accumulated property costs are derecognized, with any gain or loss included in profit or loss in the period the transaction takes place.

**ELECTRA BATTERY MATERIALS CORPORATION**

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

Management reviews its mineral property interests at each reporting period for indicators of impairment taking into consideration whether there has been a significant adverse change in the legal, regulatory, accessibility, title, environmental or political factors that could affect the property's value; whether exploration activities produced results that are *not* promising such that *no* more work is being planned in the foreseeable future and management's assessment of likely proceeds from the disposition of the property. If a property's carrying value exceeds its recoverable amount through either *not* being recoverable, being abandoned, or considered to have *no* future economic potential, the acquisition and deferred exploration and evaluation costs are written down to their recoverable amount.

Should a project be put into production, the costs of acquisition will be amortized using the units-of-production method over the life of the project based on estimated economic reserves.

***Property, Plant and Equipment***

Plant and equipment are recorded at cost less accumulated depreciation and accumulated impairment losses. The cost of an asset includes the purchase price or construction cost, any costs directly attributable to bringing the asset to the location and condition necessary for its intended use, an initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located, and borrowing costs related to the acquisition or construction of the qualifying assets.

Depreciation of plant and equipment commences when the asset is in the condition and location necessary for it to operate in the manner intended by management. Plant and equipment assets are depreciated using the straight-line method over the estimated useful life of the asset. Where an item of plant and equipment comprises of major components with different useful lives, the components are accounted for as separate items of plant and equipment. Depreciation is recognized in the consolidated statement of loss and comprehensive loss upon commercial production having been achieved.

At the date of the financial statements *no* plant and equipment assets are in use. The Company will assess the useful lives of the assets once they are put into use.

Development costs associated with bringing the Company's Refinery to the location and condition necessary for it to be capable of operating in its intended manner are capitalized as property, plant and equipment costs.

***Capital Long-Term Prepayments***

For major equipment items where milestone payments are made during the manufacturing process, these costs are initially recorded as capital long-term prepayments. Once the piece of equipment is delivered to the Refinery site, the associated cost is then reclassified to property, plant and equipment costs.

***Leases***

At inception of a contract, the Company assesses whether a 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. For such contracts, the Company recognizes a right-of-use ("ROU") asset and a lease liability at the lease commencement date.

**ELECTRA BATTERY MATERIALS CORPORATION**

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

The ROU asset is initially measured at cost, which comprises of initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and any estimated costs to dismantle or restore the underlying asset, less any lease incentives received. ROU asset is subsequently depreciated using straight-line method over the lease term, or useful life of the underlying asset if a purchase option is expected to be exercised. ROU asset is presented as part of property, plant and equipment.

Lease liabilities are initially measured at the present value of the lease payments that are *not* paid at the commencement date and subsequently measured at amortized cost using the effective interest rate method.

Lease payments for short-term leases with a term of *12* months or less, leases of low-value assets, as well as leases with variable lease payments are recognized as an expense over the term of such leases.

***Borrowing Costs***

Borrowing costs are expensed as incurred except where they relate to the financing of construction or development of qualifying assets in which case they are capitalized as property, plant and equipment up to the date when the qualifying asset is ready for its intended use.

Majority of the proceeds from the convertible notes and the government grant are being utilized for the construction and expansion of the Refinery, which given its construction timeline of over a year, is a qualifying asset under *IAS *23* Borrowing Costs*. Construction of the Refinery has *not* resumed during *2024* and no borrowing have been capitalized during the year ended *December 31, 2024.*

***Impairment***

(i)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Financial assets

For financial assets measured at amortized cost, the impairment model under IFRS *9,* Financial Instruments ("IFRS *9"*), reflects expected credit losses. The Company recognizes loss allowances for expected credit losses and changes in those expected credit losses. At each reporting date, financial assets carried at amortized cost are assessed to determine whether they are credit-impaired. A financial asset is credit-impaired when *one* or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets. The gross carrying amount of a financial asset is written off to the extent that there is *no* realistic prospect of recovery.

(ii)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Non-financial assets

Non-financial assets are evaluated at each reporting period by management for indicators that carrying value is impaired and *may not* be recoverable. When indicators of impairment are present the recoverable amount of an asset is evaluated at the CGU level, the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets, where the recoverable amount of a CGU is the greater of the CGU's fair value less costs to sell and its value in use. An impairment loss is recognized in profit or loss to the extent that the carrying amount exceeds the recoverable amount.

Previously recognized impairment losses are evaluated at each reporting period for indication that an impairment loss recognized in prior periods for an asset *may no* longer exist or *may* have decreased. If such indication exists, the Company estimates the recoverable amount of that asset, and an impairment loss is reversed only to the extent that the asset's carrying amount does *not* exceed the carrying amount that would have been determined, net of depreciation or amortization, if *no* impairment loss had been recognized.

*(expressed in thousands of Canadian dollars)*

***Assets Held for Sale***

Non-current assets, or disposal groups comprising assets and liabilities, are classified as held-for-sale if it is highly probably that they will be recovered primarily through sale rather than through continuing use. Such assets, or disposal groups, are generally measured at the lower of their carrying amount and fair value less costs to sell. Any impairment loss on a disposal group is allocated to the assets and liabilities on a pro rata basis. Impairment losses on initial classification as held-for-sale and subsequent gains and losses on remeasurement are recognized in profit or loss. Once classified as held-for-sale, property, plant, and equipment are *no* longer amortized or depreciated.

***Share capital***

Common shares are classified as equity. Transaction costs directly attributable to the issue of common shares and share options are recognized as a deduction from equity, net of any tax effects. Common shares issued for consideration other than cash, are valued based on the fair value of goods or services received.

*<u>Warrants classified as equity</u>*

Warrants classified as equity are recorded at fair value as of the date of issuance on the Company's consolidated balance sheets and *no* further adjustments to their valuation are made.

*<u>Warrants classified as liabilities</u>*

Warrants classified as derivative liabilities and other derivative financial instruments require separate accounting as liabilities are recorded on the Company's consolidated balance sheets at their fair value on the date of issuance and will be revalued on each subsequent balance sheet date until such instruments are exercised or expire, with any changes in the fair value between reporting periods recorded as other income or expense. Management estimates the fair value of these liabilities using option pricing models and assumptions that are based on the individual characteristics of the warrants or instruments on the valuation date, as well as assumptions for expected volatility, expected life, yield, and risk-free interest rate.

***Share-based payment transactions***

The Company has a long-term incentive plan that provides for the granting of options, deferred share units ("DSUs"), restricted share units ("RSUs") and performance share units ("PSUs") to officers, directors, consultants and related company employees to acquire shares of the Company.

*(i)*&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Stock options*

The fair value of the options is measured on grant date and is recognized as an expense with a corresponding increase in reserves as the options vest. Options granted to employees and others providing similar services are measured on grant date at the fair value of the instruments issued. Fair value is determined using the Black-Scholes option pricing model considering the terms and conditions upon which the options were granted. The amount recognized as an expense is adjusted to reflect the actual number of stock options that are expected to vest. Each tranche in an award with graded vesting is considered a separate grant with a different vesting date and fair value. Each grant is accounted for on that basis.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

Options granted to non-employees are measured at the fair value of the goods or services received, unless that fair value cannot be estimated reliably, in which case the fair value of the equity instruments issued is used. The value of the goods or services is recorded at the earlier of the vesting date, or the date the goods or services are received. On vesting, share-based payments are recorded as an operating expense and as reserves. When options are exercised, the consideration received is recorded as share capital. The related share-based payments originally recorded as reserves remain in reserves on either exercise or expiry of the underlying options.

*(ii)*&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Deferred, restricted and performance share units*

DSUs, RSUs and PSUs are classified as equity settled share-based payments and are measured at fair value on the grant date. The expense for DSUs, RSUs and PSUs, to be redeemed in shares, is recognized over the vesting period, or using management's best estimate when contractual provisions restrict vesting until completion of certain performance conditions, with a charge as an expense and a corresponding increase in reserves as the instrument vests. Upon exercise of any DSUs, RSUs, and PSUs, the grant date fair value of the instrument is transferred to share capital.

***Environmental rehabilitation***

An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the exploration, development or ongoing production of a mineral property interest. The estimated costs arising from the future decommissioning of plant and other site preparation work, discounted to their net present value where material, are determined, and capitalized at the start of each project to the carrying amount of the asset, as soon as the obligation to incur such costs arises. Discount rates, using a pretax rate that reflect the time value of money and risks specific to the liability, are used to calculate the net present value. Costs are charged against profit or loss over the economic life of the related asset, through amortization of the asset retirement obligation using either the unit-of-production or the straight-line method. The related liability is adjusted at each period-end with changes related to the unwinding of the discount rate accounted for in profit or loss and changes related to the current market-based discount rate or the amount or timing of the underlying cash flows needed to settle the obligation accounted for as an adjustment to the related rehabilitation asset.

***Income taxes***

Income tax expense is comprised of current and deferred taxes. Current tax and deferred tax are recognized in profit or loss, except to the extent that they relate to items recognized directly in equity or equity investments.

Current tax is the expected tax payable or receivable on the taxable income or loss for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years.

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, based on the laws that have been enacted or substantively enacted by the reporting date. Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to income taxes levied by the same tax authority for the same taxable entity. A deferred tax asset is recognized for unused tax losses, tax credits and deductible temporary differences, to the extent that it is probable that future taxable profits will be available against which they can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is *no* longer probable that the related income tax benefit will be realized.

***Income / Loss per share***

The Company presents basic and diluted income/loss per share ("LPS") data for its common shares. Basic LPS is calculated by dividing the income/loss attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the period, adjusted for own shares held. Diluted LPS is determined by adjusting the loss attributable to common shareholders and the weighted average number of common shares outstanding, adjusted for own shares held and for the effects of all dilutive potential common shares related to outstanding stock options and warrants issued by the Company. In a period of losses, the warrants, options and non-vested RSUs, PSUs and DSUs are excluded for the determination of dilutive net loss per share because their effect is anti-dilutive.

***Operating Segments***

The Company's Chief Operating Decision Maker reviews operating results and assesses performance for the Refinery and exploration and evaluation activities on a separate basis, and therefore, the Refinery and exploration and evaluation assets both meet the definition of a segment. Upon the decision to move into the full development stage of the Refinery, this business unit is now likely to earn revenue and incur expenses that are separate and discrete from the rest of the Company. The Company's operating segments are as follows:

● Refinery

● Exploration and Evaluation assets

● Corporate and Other

***Related Party Transactions***

Parties are related if *one* party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control. Related parties *may* be individuals or corporate entities and include directors and key management of the Company and its parent. A transaction is a related party transaction when there is a transfer of resources, services or obligations between related parties.

***Government Loans***

The Company received funding from the Federal Government of Canada in the form of non-interest-bearing loans. The Company records the present value of these loans, assuming a market rate of interest, as a liability in accordance with *IFRS *9* Financial Instruments*. The difference between the funding received and the present value of the loan is the benefit provided by the below market interest rate and is recorded as government grant liability. This is amortized to income over the life of the Refinery asset to which the funding related to.

The funding from the Federal Government of Canada is received as a proportion of construction costs incurred.

***Government Grant /Award***

Government grants are accounted for in accordance with IAS *20,* Accounting for Governmental Grants. Governmental Grants are recognized when they are received or receivable and when there is reasonable assurance that the Company will comply with any conditions attached to the grant.

The Company received funding from the Ontario Government and US Department of Defense in the form of a non-repayable grant. Government grants will be recognized in profit or loss on a systematic basis over the periods in which the entity recognizes as expenses the related costs for which the grants are intended to compensate. Government grants related to assets shall be presented in the statement of financial position either by setting up the grant as deferred income or by deducting the grant in arriving at the carrying amount of the asset. The Company records government grants by reducing the carrying amount of the asset.

***Convertible notes payable***

Convertible notes payable are financial instruments which contain a separate financial liability and equity instrument. These financial instruments are accounted for separately dependent on the nature of their components. The identification of such components embedded within a convertible notes payable requires significant judgement given that it is based on the interpretation of the substance of the contractual arrangement. The convertible notes are considered to contain embedded derivatives. The embedded derivatives were measured at fair value upon initial recognition and separated from the debt component of the notes. The debt component of the notes is measured at residual value upon initial recognition. Subsequent to initial recognition, the embedded derivative components are re-measured at fair value at each reporting date while the debt components are accreted to the face value of the note using the effective interest rate through periodic charges to finance expense over the term of the note. The Company elected to measure the convertible notes payable at fair value as a whole instrument ("FVO"), therefore the convertible notes payable are measured at FVTPL at their entirety.

***3.*** **Significant Accounting Judgments and Estimates**

The preparation of the Company's financial statements in conformity with IFRS® Accounting Standards as issued by the International Accounting Standard Board requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities at the date of the financial statements and reported amounts of income and expenses during the reporting period. Estimates and assumptions are continuously evaluated and are based on management's experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. However, actual outcomes *may* differ significantly from these estimates.

Judgments and estimates that have the most significant effect on the amounts recognized in the Company's consolidated financial statements are as follows:

● *Refinery Asset*

The net carrying value of the Refinery asset is reviewed regularly for conditions that suggest potential indications of impairment. The review requires significant judgment. Factors considered in the assessment of asset impairment include, but are *not* limited to, whether there has been a significant adverse change in the technological, market, economic or legal environment in which the entity operates; and internal indicators that the economic performance of the asset will be worse than expected.

*(expressed in thousands of Canadian dollars)*

● *Exploration and Evaluation Assets*

The net carrying value of each mineral property is reviewed regularly for conditions that suggest potential indications of impairment. This review requires significant judgment. Factors considered in the assessment of asset impairment include, but are *not* limited to, whether there has been a significant adverse change in the legal, regulatory, accessibility, title, environmental or political factors that could affect the property's value; whether exploration activities produced results that are *not* promising such that *no* more work is being planned in the foreseeable future and management's assessment of likely proceeds from the disposition of the property.

● *Financial Derivative Liability*

The Financial Derivative Liability values relating to convertible note and US dollar denominated warrants involve significant estimation. The fair value of financial derivative liability was determined at inception and is reviewed and adjusted on a quarterly basis or when conversions take place. Factors considered in the fair value of the financial derivative liability are risk free rate, the Company's share price, equity volatility, and credit spread.

● *Environmental Rehabilitation*

Management's determination of the Company's decommissioning and rehabilitation provision is based on the reclamation and closure activities it anticipates as being required, the additional contingent mitigation measures it identifies as potentially being required and its assessment of the likelihood of such contingent measures being required, and its estimate of the probable costs and timing of such activities and measures. Significant estimations must be made when determining such reclamation and closure activities and measures required and potentially required.

***4.*** **New Accounting Standards Issued**

Certain new accounting standards and interpretations have been published that are either applicable in the current year or *not* mandatory for the current period. The Company adopted amendments to IAS *1* – Non-current liabilities with covenants and determined a reclassification of the convertible notes from long-term to current liabilities during the current period. The amendments clarify certain requirements for determining whether a liability should be classified as current or non-current and require new disclosures for non-current liabilities that are subject to covenants within *12* months after the reporting period. This resulted in a change in the accounting policy for classification of liabilities that can be settled in the Company's own shares (e.g. convertible notes issued by the Company). Previously, the Company excluded all counterparty conversion options when classifying the related liabilities as current or non-current. Under the revised policy, when a liability includes a counterparty conversion option that *may* be settled by a transfer of a Company's own shares, the Company takes into account the conversion option in classifying the host liability as current or non-current except when it is classified as a equity component of a compound instrument. The Company's other liabilities were *not* impacted by the amendments.

Majority of the Company's property, plant, and equipment assets relate to the Refinery located near Temiskaming Shores, Ontario, Canada. The carrying value of property, plant, and equipment is $51,059 (*December 31, 2023 -* $51,063), all of which is pledged as security for the *2028* Notes (Note *11*).

During the year ended *December 31, 2023,* an impairment charge was recognized on the Refinery in Ontario. The impairment loss of $49,743 was determined based on the recoverable amount of the Refinery cash generating unit ("CGU") that was based on value in use, assuming that commercial production will commence in *2026,* and applying a discount rate of 20% and a terminal multiple of 4.75. The recoverable amount of the Refinery CGU was determined as $44,899. In addition, costs of $2,141 related to the black mass program were included in the impairment charge.

During the year ended *December 31, 2024,* the Company performed their annual impairment assessment and determined based on *third* party appraisal, the fair value less costs of disposal was determined to be higher than the carrying value of the Refinery CGU, resulting in no impairment charge.

Capitalized development costs for the year ended *December 31, 2024* totaled $Nil (*2023* - $16,942) of which capitalized borrowing costs were $Nil (*December 31, 2023 -* $2,781). Capital long-term prepayments of $139 (*December 31, 2023 -* $Nil) relate to payments for long-term capital contracts made for Refinery equipment that have yet been received by the Company as at *December 31, 2024.* No depreciation has been recorded for the Refinery in the current year (*December 31, 2023* and *2022* $Nil) as the asset is *not* yet in service.

All of the Iron Creek mineral properties are pledged as security for the Convertible Notes issued on *February 13, 2023* and *November 27, 2024 (*Note *11*). Upon successful commissioning of the Refinery, the Iron Creek mineral properties will be released from the Convertible Notes security package.

Certain claims relating to the Iron Creek properties were acquired by the Company against earn-in and option agreements entered with the original owners of such claims. These agreements provide a working interest in the property to the Company, upon making certain milestone payments and/or incurring certain expenditures on the property. The claims are also subject to future net smelter royalty ("NSR") payments.

***8.*** **Marketable Securities**

Marketable securities represent Kuya Silver Corp ("Kuya") shares held by the Company. The Kuya shares were acquired via the Kerr Assets sale on *February 26, 2021* and *January 31, 2023* described below (*"2023* Sale"). The total value of marketable securities at *December 31, 2023* was $595 (*December 31, 2022* - $433). These shares were marked-to-market at *December 31, 2023* resulting in a net loss of $253 being recorded during the year ended *December 31, 2023* (*December 31, 2022* – loss of $589).

On *January 31, 2023,* the Company completed the sale of the remaining assets of Canadian Cobalt Camp consisting of Keely-Frontier patents ("Cobalt Camp") which Kuya did *not* own, as well as their associated asset retirement obligations. To complete the sale, Kuya issued to the Company 777,027 shares at a deemed price of $1.48 per share (being the share price equivalent to the VWAP prior to issuance) comprised of 675,676 shares as consideration for the $1,000 sale and an additional 101,351 to settle $150 of payables to the Company. Kuya had also entered into a royalty agreement with the Company whereby it will grant the Company a two percent royalty on net smelter returns from commercial products derived from the remaining assets. The Company will retain a right of *first* offer to refine any base metal concentrates produced from the assets at the Company's Ontario refinery.

Marketable securities represent Kuya Silver Corp ("Kuya") shares held by the Company. The Kuya shares were acquired via the Kerr Assets sale on *February 26, 2021* and *January 31, 2023* described below (*"2023* Sale"). The total value of marketable securities at *December 31, 2024* was $12 (*December 31, 2023* - $595). These shares were marked-to-market at *December 31, 2024* resulting in a unrealized gain of $41 being recorded during the year ended *December 31, 2024* (*December 31, 2023* – loss of $253 and *December 31, 2022 –* loss of $589). During the year ended *December 31, 2024,* the Company sold marketable securities for proceeds of $930 from sale of 2,332,000 shares (the year ended *December 31, 2023 –* $816 from sale of 1,719,500 shares) and realized gains of $306 for the year ended *December 31, 2024 (*the year ended *December 31, 2023 –* gain of $90 and *December 31, 2022 –* loss of $220).

***9.*** **Asset Retirement Obligations**

As at *December 31, 2024,* the estimated cost of closure is $3,323. The Company maintains a surety bond for $3,450 as financial assurance based on the *October 2021* closure plan.

The full estimated closure cost in the new closure plan incorporated a number of new disturbances that have yet to take place, such as new roadways, new chemicals on site, and a new tailings area. The new closure plan also included cost updates relating to remediating disturbances that existed at *December 31, 2024.* The following assumptions were used to calculate the asset retirement obligation:

● Discounted cash flows of $2,842 (*December 31, 2023* - $3,126)

● Closure activities date of *2073* (*December 31, 2023* – *2037*)

● Risk-free discount rate of 3.33% (*December 31, 2023* – 3.98%)

● Long-term inflation rate of 3.0% (*December 31, 2023* – 3.0%)

The continuity of the asset retirement obligation at *December 31, 2024* and *2023* is as follows:

***10.*** **Long-Term Government Loan Payable and Government Grant**

On *November 24, 2020,* the Company had entered into a contribution agreement with the Ministry of Economic Development and Official Languages as represented by the Federal Economic Development Agency for Northern Ontario ("FedNor") for up to a maximum of $5,000 financing related to the recommissioning and expansion of the Refinery in Ontario. The contribution was to be in the form of debt bearing a 0% interest rate and funded in proportion to certain Refinery construction activities. The Company received approval for an additional $5,000 funding under the agreement on *December 27, 2023,* which was fully received during the year ended *December 31, 2024.*

Once construction is completed, the cumulative balance borrowed will be repaid in 19 equal quarterly instalments. The funding is provided pro rata with incurred Refinery construction costs, with all other conditions required for the funding having been met. The loan is discounted using a market rate between 7.0% and 17.1% with the resulting difference between the amortized cost and cash proceeds recognized as Government Grant. The FedNor loan requires completion of the construction on or before *June 30, 2025.* The Company is currently in negotiations to extend the commencement of payments based on the Company's latest estimated construction completion date.

***11.*** **Convertible Note Arrangement** 

On *February 13, 2023,* the Company completed subscription agreements with certain institutional investors in the United States with respect to $68,049 (US$51,000) principal amount of 8.99% senior secured notes due *February 2028 ("2028* Notes"). The initial conversion rate of the Notes is 100,804 common shares per US$1,000 principal amount of Notes (equivalent to an initial conversion price of approximately US$9.92 per common share) subject to certain adjustments set forth in the *2028* Notes. The *2028* Notes are convertible at the discretion of the lenders. The *2028* Notes bear interest at 8.99% per annum, payable in cash or common shares semi-annually in arrears in *February* and *August* of each year and mature in *February 2028.* In the event the Company achieves a *third*-party green bond designation during the term of the note indenture, the interest rate on future cash interest payments shall be reduced to 8.75% per year.

The investors in the offering also received an aggregate of 2,699,014 warrants to purchase common shares (*"2028* Warrants") in the Company. The *2028* Warrants are exercisable for five years at an exercisable price US$9.92, subject to certain adjustments. Certain terms of the *2028* Warrants were amended in *2024* as discussed below.

Upon early conversion of the *2028* Notes, the Company will make an interest make whole payment equal to the lesser of the two years of interest payments or interest payable to maturity, which *may* be made in cash or shares at the Company's discretion. The investors also received a royalty of: (i) 0.6% on "Operating Revenue" from the sale of all cobalt produced from the Refinery payable in the *first twelve* months following a defined threshold of commercial production, where Operating Revenue consists of revenue from the Refinery less certain permitted deductions; and (ii) 0.6% on all revenue from sales of cobalt generated from the Refinery in the *second* to *fifth* years following the commencement of commercial production. Royalty payments under the royalty agreements are subject to a cumulative cap of US$6,000.

*(expressed in thousands of Canadian dollars)*

The Company used a portion of the proceeds of the *2028* Notes offering to purchase all of the outstanding convertible notes consisting of $48,035(US$36,000) of existing 6.95% senior secured notes due *December 2026 ("2026* Notes") for cancellation at par, as well as to pay accrued and unpaid interest on the *2026* Notes through the closing date of the *2028* Notes offering for US$51,000 ($68,049). The net proceeds were $20,013, before interest payment of $1,656 and transaction costs of $2,340. As the terms of the *2028* Notes are substantially different from the *2026* Notes, the Company accounted for the *2026* Notes as an extinguishment of the original financial liability and recognized a new financial liability for the *2028* Notes. The extinguishment of *2026* Notes and recognition of *2028* Notes resulted in a loss of $18,727 as determined below.

The *2028* Notes contains components of Convertible Notes, Warrants, and a Royalty. Based on the *2028* Notes agreements, these components are separately exercisable hence the Company has accounted for each as a freestanding financial instrument and initially recorded these components at fair value. They have been recorded as derivative liabilities until they are elected to conversion to common shares.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

As at initial recognition on *February 13, 2023,* the embedded derivatives were fair valued using the finite difference valuation method with the following key assumptions:

● Risk free rate at *February* of *13, 2023* of 3.96% based on the US dollar *zero* curve;

● Equity volatility at *February 13, 2023* of 56% based on an assessment of the Company's historical volatility and the estimated maximum a *third*-party investor would be willing to pay for;

● An Electra share price at *February 13, 2023* of $8.92 reflecting the quoted market prices; and

● A credit spread at *February 13, 2023* of 28.9%.

In addition, subject to certain conditions, the noteholders have agreed to waive the requirement set out in the *2028* Notes for the Company to file a registration statement to provide for the resale of the common shares underlying the *2028* Notes and the common share purchase warrants issued on *February 13, 2023.*

In *January 2024,* the terms of the *2028* Warrants were amended and the exercise price of US$9.92 was re-priced to $4.00. On *November 27, 2024,* in conjunction with the issuance of the *2027* Notes discussed below, the exercise price was amended from $4.00 to $3.40.

In addition, the *2028* Warrants now include a revised acceleration clause such that their term will be reduced to thirty-day in the event the closing price of the common shares on the TSXV exceeds $3.40 by twenty percent or more for ten consecutive trading dates, with the reduced term beginning seven calendar days after such 10 consecutive trading-day period. Upon the occurrence of an acceleration event, noteholders of the *2028* Warrants *may* exercise the *2028* Warrants on a cashless basis, based on the value of the *2028* Warrants at the time of exercise.

On *March 21, 2024,* the Company satisfied $543(US$401) of the interest through the issuance of 210,760 common shares to certain noteholders. The share issuance was approved by the TSXV.

The *2028* Notes are secured by a *first* priority security interest (subject to customary permitted liens) in substantially all of the Company's assets, and the assets and/or equity of the secured guarantors. The *2028* Notes are subject to customary events of default and basic positive and negative covenants. The Company is required to maintain a minimum liquidity balance of US$2,000 under the terms of the *2028* Notes. The *2028* Notes are convertible at the discretion of the lenders and as such have been classified as a current liability.

On *November 27, 2024,* the Company has also issued additional *2028* Notes to the noteholders, in the principal amount of $9,157(US$6,521), as payment-in-kind for all outstanding accrued interest owing on the *2028* Notes through to *August 15, 2024.* The additional *2028* Notes carry the same payment conversion terms as the balance of the *2028* Notes and were issued pursuant to a supplement to the indenture dated *February 13, 2023,* entered into among the Company and the *2028* Notes noteholders.

For the year ended *December 31, 2024,* the embedded derivatives were fair valued using the finite difference valuation method with the following key assumptions:

● Risk free rate at *December 31, 2024* of 4.393% (*December 31, 2023* – 3.85%) based on the US dollar *zero* curve;

● Equity volatility at *December 31, 2024* of 63% (*December 31, 2023* – 62%) based on an assessment of the Company's historical volatility and the estimated maximum a *third*-party investor would be willing to pay for;

● An Electra share price at *December 31, 2024* of US$1.807 (*December 31, 2023* - US$1.460) reflecting the quoted market prices; and

● A credit spread at *December 31, 2024* of 26.3% (*December 31, 2023* – 27.8%).

On *November 27, 2024,* the Company closed a financing transaction (the *"2027* Notes") with the holders of the *2028* Notes for gross proceeds of $5,615 (US$4,000). In connection with closing, 460,405 common shares were issued for gross proceeds of $1,401 at US$2.172 per share. The *2027* Notes were issued together with 1,136,364 detachable common share purchase warrants (*"2027* Warrants") entitling the noteholders to acquire equivalent number of common shares at a price of $4.00 per share until *November 26, 2026.* The *2027* Warrants were issued as replacement warrants for previously issued equity financing which took place on *August 23, 2023* with an exercise price of $6.84. The same number of warrants were cancelled and re-issued as part of the *2027* Notes. *2027* Warrants met the fixed for fixed criteria and were classified as equity. The total proceeds were allocated between convertible notes and warrants using relative fair value on the issuance date. The fair value of warrants on issuance date was estimated using Black-Scholes Option Pricing Model approach with the following main inputs: a risk-free rate of 3.20% per year, an expected life of 2 years, expected volatility based on historical prices in the range of 70.00%, no expected dividends and a share price range of $2.72.

As at initial recognition on *November 27, 2024,* the convertible notes were fair valued using the finite difference valuation method with the following key assumptions:

● Risk free rate at *November 27, 2024* of 4.268% based on the US dollar *zero* curve;

● Equity volatility at *November 27, 2024* of 63% based on an assessment of the Company's historical volatility and the estimated maximum a *third*-party investor would be willing to pay for;

● An Electra share price at *November 27, 2024* of US$1.938 reflecting the quoted market prices; and

● A credit spread at *November 27, 2024* of 26.0%.

The transaction costs relating to the *2027* Notes and equity financing in the amount of $903 were allocated between *2027* Notes, *2027* Warrants and equity based on relative fair value on issuance date in the amount of $633, $89 and $180, respectively. The transaction costs for debt related to *2027* Notes were recorded in the consolidated statements of loss and other comprehensive loss in other non-operating loss. The transaction costs for the *2027* Warrants and equity were deducted from reserves and common shares, respectively in the consolidated statements of equity.

On *November 15, 2022,* 586,250 warrants were issued to subscribers in the Company's best-efforts, overnight-marketed offering. As Warrants issued are denominated in foreign currency that is different from the Company's functional currency, the warrants are determined to be financial derivative liabilities and the total fair value of US$2,087 was recorded as such. The fair value of the warrants was estimated using the Monte Carlo Simulation Model assuming a risk-free interest rate of 4.172%, an expected volatility of 62.89%, share price of US$9.40, strike price of US$12.40.

As part of the *November 15, 2022* Offering, 34,538 Broker Warrants Units (consisting of *one* common share and *one* warrant) were issued as transaction costs. The Broker Warrants are equity-settled and was issued for services received; hence the Company has recorded US$325 in reserve, which was measured at fair value of services received.

During the year ended *December 31, 2022,* 52,636 warrants of the Company were exercised for gross proceeds of $807. The Company issued a total of 620,788 share purchase warrants in conjunction with its *November 2022* best - efforts, overnight - marketed offering. During the year ended *December 31, 2022,* a total of 20,803 warrants expired.

On *August 11, 2023,* 4,886,364 warrants were issued to subscribers in the Company's private placement (Note *13*). The total value of $6,321 was recorded in reserves. The fair value of the warrants were estimated using the Black-Scholes Option Pricing Model assuming a risk-free interest rate of 4.68%, an expected life of 2 years, an expected volatility of 66.07%, no expected dividends, and a share price of $4.76. As part of the private placement, the Company issued 225,000 Broker Warrants as transaction costs. The Company recorded $990 in reserve, which was measured at fair value of services received.

During the year ended *December 31, 2023,* the Company issued 2,699,014 warrants in conjunction with *2028* Notes (Note *11*). No warrants were exercised during the year ended *December 31, 2023.* Total of 245,257 warrants expired during the year ended *December 31, 2023.* During the year ended *2024,* the exercise price of the of the *2028* Warrants was amended as detailed in Note *11.* In addition, the warrants were to be amended to include an acceleration clause such that the term of the warrants will be reduced to *30*-days (the "Reduced Term") in the event the closing price of the common shares on the TSXV exceeds $4.80 *ten* consecutive days trading days (the "Acceleration Event"), with the Reduced term to begin upon release of a press release by the Company within *seven* calendar days after such *ten* consecutive trading day period. Upon the occurrence of an Acceleration Event, holders of the warrants *may* exercise the warrants on a cashless basis, based on the value of the warrants at the time of exercise.

On *November 27, 2024,* in connection with the *2027* Notes, 1,136,364 detachable common share purchase warrants were issued as detailed in Note *11,* which replaced *2023* private placement warrants.

The basic loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding during the period. The diluted loss per share reflects the potential dilution of common share equivalents, such as outstanding stock options, and share purchase warrants, in the weighted average number of common shares outstanding during the period, if dilutive.

Conversion option, share purchase warrants and stock options were excluded from the calculation of diluted weighted average number of common shares outstanding for the years ended *December 31, 2024, 2023* and *2022* as the warrants and stock options were anti-dilutive.

***18.*** **Financial Instruments** 

***Liquidity Risk***

Liquidity risk is the risk that the Company will *not* be able to meet its financial obligations as they fall due. Per Note *1,* the Company does *not* have sufficient financial resources necessary to complete the construction and final commissioning of the Refinery and the Company is going through a planning and budgeting process to update the capital estimates and completion schedule associated with the Refinery. The Company attempts to ensure there is sufficient access to funds to meet ongoing business requirements, considering its current cash position and potential funding sources. Although the Company has historically been successful in obtaining financing in the past, there can be *no* assurances that the Company will be able to obtain adequate financing in the future. This represents a material uncertainty that casts substantial doubt on the Company's ability to continue as a going concern. These consolidated financial statements do *not* include the adjustments to the amounts and classifications of assets and liabilities that would be necessary should the Company be unable to continue as a going concern. These adjustments *may* be material.

The following are the contractual maturities of financial liabilities as at *December 31, 2024* and *December 31, 2023:*

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

For *2024* and *2023* the Company assumed the notes will remain outstanding until maturity. If noteholders convert prior to maturity, they would be entitled to a make-whole interest payment upon conversion. This payment cannot exceed the remaining coupon payments owing and thus the tables above present all interest payments to maturity, which represents the maximum possible cash outflow to the Company.

The contractual liabilities relating to government loan payable assumes that repayment would began on *June 30, 2025* in *19* equal quarterly instalments.

***Fair Value***

The Company's financial instruments consisted of cash and cash equivalents, restricted cash, convertible notes payable, long-term government loan payable, warrants liability, and accounts payable and accrued liabilities. The fair values of cash and cash equivalents, restricted cash, prepaid expenses and deposits, receivables and accounts payable and accrued liability approximate their carrying values because of their current nature. The fair value of long-term government loan payables are estimated as $7,824 (*December 31, 2023 -* $4,299) utilizing a discounted cash flow calculation based on cash interest and principal payments and an interest rate ranging from 7.0% to 17.1% (*December 31, 2023 –* 9%) which would expected to be achieved on a standard debt arrangement.

***Credit Risk***

Credit risk is the risk that *one* party to a financial instrument will fail to discharge an obligation and cause the other party to incur a financial loss. The Company's primary exposure to credit risk is on its cash and cash equivalents and restricted cash which are being held in with major Canadian banks that are high credit quality financial institutions as determined by rating agencies.

The Company's receivables primarily consist of HST refund due from Canada Revenue Agency and reimbursement to be received from NRCan and DoD, hence there is *no* significant credit risk on receivables.

As at *December 31, 2024,* the Company's maximum exposure to credit was the carrying value of cash and cash equivalents, restricted cash, and receivables.

***Foreign Currency Risk***

Foreign currency risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because they are denominated in currencies that differ from the Company's functional currency. The Company is exposed to foreign currency risk on fluctuations related to cash and cash equivalents, prepayments, accounts payable and accrued liabilities, derivative financial liabilities on warrants and its long-term debts that are denominated in US Dollars. The Company has *not* used derivative instruments to reduce its exposure to foreign currency risk nor has it entered into foreign exchange contracts to hedge against gains or losses from foreign exchange fluctuations. The following table indicates the foreign currency exchange risk on monetary financial instruments as at *December 2024* and *2023* converted to Canadian Dollars:

| Royalty | (858) |
| Financial derivative liability – Convertible Notes | (1421) |
| Embedded derivative liability (US Warrant) | (7) |
| Total | $(49418) |

---

During the year ended *December 31, 2024,* the Company recognized a loss of $4,338 on foreign exchange (*2023* – loss of $1,485 and *2022* – loss of $1,019). Based on the above exposures as at *December 31, 2023,* a *10%* depreciation or appreciation of the US Dollar against the Canadian Dollar would result in a $6,149 decrease or increase in the Company's net income before tax (*2023* - $3,610 and *2022* - $2,480).

***Interest Rate Risk***

Interest rate risk is the risk that the fair value of future cash flow of a financial instrument will fluctuate because of changes in market interest rate. The Company currently does *not* have any financial instruments that are linked to LIBOR, SOFR, or any form of a floating market interest rate. Therefore, changes in the market interest rate does *not* have an impact on the Company as at *December 31, 2024.*

***19.*** **Management of Capital**

The Company's objectives when managing capital are to ensure it has sufficient cash available to support its future Refinery expansion and exploration activities; and ensure compliance with debt covenants under the convertible notes arrangement.

The Company manages its capital structure, consisting of cash and cash equivalents, share capital and debt (convertible notes and loans), and will make adjustments to it depending on the funds available to the Company for its future Refinery expansion and exploration activities. The Board of Directors does *not* establish quantitative return on capital criteria for management, but rather relies on the expertise of the Company's management to sustain future development of the business.

Management reviews its capital management approach on an ongoing basis and believes that this approach, given the size of the Company, is reasonable. Other than the minimum liquidity balance covenant under the convertible note arrangement, the Company is *not* subject to externally imposed capital requirements. The convertible notes arrangement does *not* impose any quantitative ratio covenants on the Company in the course of the normal construction and operation of its current assets.

***20.*** **Fair Value Measurements**

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy, described, as follows, based on the lowest-level input that is significant to the fair value measurement as a whole:

Level *1* — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level *2* — Quoted prices in markets that are *not* active or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level *3* — Prices or valuation techniques that require inputs that are both significant to the fair value measurement and 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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

<u>Valuation techniques</u>

A) Marketable securities

Marketable securities are included in Level *1* as these assets are quoted on active markets.

B) Financial Derivative Liability – Convertible Notes

For the convertible notes payable designated at fair value through profit or loss, the valuation is derived by a finite difference method, whereby the convertible debt as a whole is viewed as a hybrid instrument consisting of *two* components, an equity component (i.e., the conversion option) and a debt component, each with different risk. The key inputs in the valuation include risk-free rates, share price, equity volatility, and credit spread. As there are significant unobservable inputs used in the valuation, the convertible notes payable is included in Level *3.*

Methodologies and procedures regarding Level *3* fair value measurements are determined by the Company's management. Calculation of Level *3* fair values is generated based on underlying contractual data as well as observable and unobservable inputs. Development of unobservable inputs requires the use of significant judgment. To ensure reasonability, Level *3* fair value measurements are reviewed and validated by the Company's management. Review occurs formally on a quarterly basis or more frequently if review and monitoring procedures identify unexpected changes to fair value.

While the Company considers its fair value measurements to be appropriate, the use of reasonably alternative assumptions could result in different fair values. On a given valuation date, it is possible that other market participants could measure a same financial instrument at a different fair value, with the valuation techniques and inputs used by these market participants still meeting the definition of fair value. The fact that different fair value measurements exist reflects the judgment, estimates and assumptions applied as well as the uncertainty involved in determining the fair value of these financial instruments.

The fair value of the convertible note payable has been estimated based on significant unobservable inputs which are equity volatility and credit spread. The Company used an equity volatility of 63% (*December 31, 2023 –* 62% and *December 31, 2022 –* 54%). If the Company had used an equity volatility that was higher or lower by *10%,* the potential effect would be an increase of $963 (*December 31, 3023* - $545) or a decrease of $826 (*December 31, 2023 -* $425) to the fair value of the convertible note payable. The Company used a credit spread of 26.3% (*December 31, 2023* – 27.8% and *December 31, 2022 –* 30.5%). If the Company had used a credit spread that was higher or lower by *5%,* the potential effect would be a decrease of $4,273 (*December 31, 2023 -* $3,937 and *December 31, 2022 -* $352) or an increase of $4,901 (*December 31, 2023 -* $4,648 and *December 31, 2022 -* $474) to the fair value of convertible note payable.

The fair value of the *2027* Notes has been estimated based on significant unobservable inputs which are equity volatility and credit spread. The Company used an equity volatility of 63% (*December 31, 2023 –* Nil). If the Company had used an equity volatility that was higher or lower by *10%,* the potential effect would be an increase of $204 (*December 31, 2023 -* $Nil) or a decrease of $198 (*December 31, 2023 -* $Nil) to the fair value of the convertible note payable. The Company used a credit spread of 26.3% (*December 31, 2023 –* Nil). If the Company had used a credit spread that was higher or lower by *5%,* the potential effect would be a decrease of $218 (*December 31, 2023 -* $Nil) or an increase of $275 (*December 31, 2023 –* $Nil) to the fair value of convertible note payable.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED *DECEMBER 31, 2024, 2023* AND *2022*

*(expressed in thousands of Canadian dollars)*

C) Warrants – Convertible Notes

The Warrants issued in a foreign currency and accounted for at fair value through profit or loss are valued using a Monte Carlo Simulation Model to better model the variability in exercise date. The key inputs in the valuation include risk-free rates and equity volatility. As there are significant unobservable inputs used in the valuation, the financial derivative liability is included in Level *3.*

The fair value of the Warrants has been estimated using a significant unobservable input which is equity volatility. The Company used an equity volatility of 63% (*December 31, 2023 –* 62%). If the Company had used an equity volatility that was higher or lower by *10%,* the potential effect would be an increase of $200 (*December 31, 2023 –* $186) or a decrease of $227 (*December 31, 2023 –* $327) to the fair value of the Warrants.

The fair value of the *2027* Warrants has been estimated using a significant unobservable input which is equity volatility. The Company used an equity volatility of 70% (*December 31, 2023 –* Nil). If the Company had used an equity volatility that was higher or lower by *10%,* the potential effect would be an increase of $161 (*December 31, 2023 -* $Nil) or a decrease of $163 (*December 31, 2023 -* $Nil) to the fair value of the Warrants.

D) Royalty

The fair value of the Royalty has been estimated at inception using a discounted cash flow model. The key inputs in the valuation include the effective interest rate of 19.20% and cash flows estimates of future operating and gross revenues. As there are significant unobservable inputs used in the valuation, the Royalty is included in Level *3.* A *10%* increase or decrease in the effective interest rate would be an increase of $250 (*December 31, 2023* –$96) or of decrease $213 (*December 31, 2023* –$109) to the fair value of the royalty.

E) Other Financial Derivative Liability (US Warrants)

The fair value of the embedded derivative on Warrants issued in foreign currency as at *December 31, 2024* was $Nil (*December 31, 2023 -* $7 and *December 31, 2022 -* $1,271) and is accounted for at FVTPL. The valuation of warrants where the strike price is in US dollar and the warrants can be exercised at a time prior to expiry, the Company uses a Monte Carlo Simulation Model to better model the variability in exercise dates. The key inputs in the valuation include risk-free rates and equity volatility. As there are significant unobservable inputs used in the valuation, the financial derivative liability is included in Level *3.*

***21.*** **Commitments and Contingencies**

From time to time, the Company and/or its subsidiaries *may* become defendants in legal actions and the Company intends to defend itself vigorously against all legal claims. Electra is *not* aware of any unrecorded claims against the Company that could reasonably be expected to have a materially adverse impact on the Company's consolidated financial position, results of operations or the ability to carry on any of its business activities. The Company has negotiated settlement on *one* claim as at *March 31, 2025.* The amount due is approximately $140 (*December 31, 2024 -* $140) has been recorded in accounts payable and accrued liabilities and the respective lien has been discharged. Additionally, certain legal claims against the Company were settled in *2024.*

As at *December 31, 2024,* the Company's commitments relate to purchase and services commitments for work programs relating to Refinery expansion and payments under financing arrangements. The Company had the following commitments as at *December 31, 2024.*
