MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL REPORTING

The accompanying unaudited condensed interim consolidated financial statements of Sigma Lithium Corporation (the "Company") are the responsibility of management and have been approved by the Company's Board of Directors (the "Board").

The unaudited condensed interim consolidated financial statements have been prepared by management on a going concern basis in accordance with International Accounting Standard 34 Interim Financial (“IAS 34”) as issued by the International Accounting Standards Board (“IASB”). When alternative accounting methods exist, management has chosen those it deems most appropriate in the circumstances. Financial statements are not exact since they include certain amounts based on estimates and judgments. Management has determined such amounts on a reasonable basis in order to ensure that the financial statements are presented fairly, in all material respects.

The Board is responsible for ensuring that management fulfills its responsibilities for financial reporting and is ultimately responsible for reviewing and approving the financial statements. The Board carries out this responsibility principally through its Audit Committee.

The Audit Committee is appointed by the Board, and all of its members are independent directors. The Audit Committee meets at least four times a year with management, and with the independent auditors, KPMG Auditores Independentes Ltda., at least for the year-end audit, to discuss internal controls over the financial reporting process, auditing matters and financial reporting issues, to satisfy itself that each party is properly discharging its responsibilities, and to review the quarterly and the annual reports, the unaudited condensed interim consolidated financial statements, and the independent auditors’ reports. The Audit Committee reports its findings to the Board for consideration when approving the consolidated financial statements for issuance to the shareholders. The Audit Committee also considers, for review by the Board and approval by the shareholders, the engagement of the independent auditors.

The accompanying notes to the unaudited condensed interim consolidated financial statements are an integral part of these statements.

Sigma Lithium Corporation (the “Company”) is a mineral processing and development company incorporated under the Canada Business Corporations Act. The Company's common shares commenced trading on Nasdaq Capital Market ("Nasdaq") under the symbol "SGML" and on the TSX Venture Exchange (the “TSXV”) under the symbol "SGML”. The head office of the Company is Suite 2200, 885 West Georgia Street, Vancouver, British Columbia, V6E 3E8.

These unaudited condensed interim consolidated financial statements include the Company’s wholly owned subsidiary Sigma Lithium Holdings Inc. (“Sigma Holdings”), which is domiciled in Canada and incorporated under the Business Corporations Act (British Columbia), and its indirect wholly owned Brazil-incorporated subsidiary Sigma Mineração S.A. ("Sigma Brazil").

Sigma Brazil holds a 100% interest in four mineral properties: Grota do Cirilo, São Jose, Santa Clara, and Genipapo, located in the municipalities of Araçuaí and Itinga, in the Vale do Jequitinhonha region in the State of Minas Gerais, Brazil (together, the "Lithium Properties").

Sigma Brazil initiated its operations and the first shipment of 30,000 tons was completed on July 27:

These unaudited condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard 34 - Interim Financial Reporting.

These unaudited condensed interim consolidated financial statements do not include all disclosures required by IFRS for annual audited consolidated financial statements and accordingly should be read in conjunction with the Company’s annual audited consolidated financial statements for the year ended December 31, 2022.

The accounting policies, accounting estimates and judgments, risk management and measurement methods applied in these unaudited condensed interim consolidated financial statements are consistent with those used in the Company’s audited annual consolidated financial statements for the year ended December 31, 2022.

These unaudited condensed interim consolidated financial statements have been prepared on a going concern basis on the assumption that the Company will continue to operate for the next 12 (twelve) months and foreseeable future and be able to realize its assets and discharge its liabilities in the normal course of business.

Critical Accounting Estimates

Significant assumptions about the future and other sources of estimation uncertainty that management has made at the financial position reporting date, that could result in a material adjustment to the carrying amounts of assets and liabilities, relate to, but are not limited to, the following:

New IFRS Pronouncements

Amendments to IAS 1 – Presentation of Financial Statements

In October 2022, the IASB issued amendments to IAS 1, Presentation of Financial Statements titled Non-current liabilities with covenants. These amendments sought to improve the information that an entity provides when its right to defer settlement of a liability is subject to compliance with covenants within 12 months after the reporting period. These amendments to IAS 1 override but incorporate the previous amendments, Classification of liabilities as current or non-current, issued in January 2020, which clarified that liabilities are classified as either current or non-current, depending on the rights that exist at the end of the reporting period. Liabilities should be classified as non-current if a company has a substantive right to defer settlement for at least 12 months at the end of the reporting period. The amendments are effective January 1, 2024, with early adoption permitted. Retrospective application is required on adoption. We do not expect these amendments to have a material effect on Q1 2023 financial statements.

Amendment to IAS 1 and IFRS Practice Statement 2 - Disclosure of Accounting Policies

In February 2021, the IASB issued amendments to IAS 1, Presentation of Financial Statements and the IFRS Practice Statement 2 Making Materiality Judgements to provide guidance on the application of materiality judgments to accounting policy disclosures. The amendments to IAS 1 replace the requirement to disclose significant accounting policies with a requirement to disclose material accounting policies. Guidance and illustrative examples are added in the Practice Statement to assist in the application of the materiality concept when making judgments about accounting policy disclosures. The amendments are effective January 1, 2023. Prospective application is required on adoption. These amendments did not impact the Q1 2023 financial statements.

These unaudited condensed interim consolidated financial statements were authorized for issue by the Company’s Board of Directors on August 10, 2023.

Cash and cash equivalents include the following:

Prepaid expenses include the following:

(*) Related to 12 months of interest which has been paid in advance on the export prepayment agreement as described in note 8.

The assets under construction include $516 capitalized related to RSUs during the three months ended March 31,2023 (year ended December 31, 2022 - $2,404).

The Company is subject to the following royalties:

Due to the advancement of the Company’s project and significant spend as well as assessed likelihood of reaching production and exercising the option, the Company recognized the fair value of the royalty agreement call option of US$3,800 as at June 30, 2022. As a result, the Company recorded a current liability in the consolidated statement of financial position and an expense in the consolidated statement of net loss and comprehensive loss, in the amount of US$3,800 ($4,892). As of March 31, 2023, the current liability related to the royalty agreement call option was $5,136.

The Company exercised the Amilcar Royalty Agreement call option on April 13, 2023.

The depreciation of $237 was recorded of (i) $34 as an expense, (ii) $119 allocated to another assets of property, plant and equipment and (iii) $84 allocated to exploration and evaluation assets.

The Company has mineral properties in the exploration and evaluation stage and follows the practice of capitalizing all costs relating to the acquisition and exploration of mineral rights. Such costs include, among others, geological, geophysical studies, exploratory drilling and sampling, feasibility studies and technical reports.

A summary of exploration costs is set out below:

(*) The additions include $ 340 related to RSUs during the three months ended March 31,2023 (year ended December 31, 2022 - $8,528).

On January 13, 2023, the Company received an amount of R$ 11,731 thousand (equivalent to $3,054) arising from a financing contract entered into with BDMG on November 14, 2022. The financing has monthly interest payments and a grace period of 24 (twenty-four) months for the principal repayment. The principal repayment is made in 60 (sixty) Monthly installments, with the first installment due on December 15, 2024. The financing cost is 3.75% per year.

On December 13, 2022, the Company, through Sigma Brazil, entered into an export prepayment agreement in the amount of USD $100 million (“Loan”), with annual interest payment based on the 12-month Bloomberg short-term bank yield index “BSBY” plus 6.95% per annum and maturing on December 13, 2026. On December 13, 2022, Sigma Brazil drew down USD $60 million (equivalent to $82 million). The balance of USD $40 million (equivalent to $54 million) was disbursed in two subsequent drawdowns of USD $20 million each, on February 28, 2023 and on March 16, 2023.

The Company paid $10,194 of interest in advance in December 2022 and $6,840 paid of interest in advance on first quarter of 2023, an amount equal to twelve months of payable interest, and an upfront fee of $3,665. Such amount of interest in advance is an estimate for the 12-month period and shall be compared with the actual monthly accrued interest throughout the period. Any difference between the two calculated interest amounts (estimate vs accrued), positive or negative, shall be settled on the first anniversary of the export prepayment agreement. During the first quarter the amount of interest accrued was $3,608 of which $3,043 was accounted for as prepaid expenses and will be charged against income on a monthly basis over the period of the contract.

Beginning on November 18, 2023, principal repayments of the Loan are due 48 days after the end of the Company’s first and third quarters ending March 31 and September 30, respectively. Repayments will be determined based on an amount equivalent to 50% of its net cash generated from operating activities plus net cash generated from investing activities for the prior 6-month period ended March 31 and September 30. Considering the Company’s estimated 2023 production, using a spodumene price of US$3,200/ton, it is expected that the Company will not be required to repay the Loan in 2023, and, therefore, has been classified as a non-current liability as at December 31, 2022.

The Loan contains an embedded prepayment feature, whereby Sigma Brazil has to pay an early prepayment premium of 4% during the first year of the Loan, reducing proportionately from 4% to 1% after the first anniversary, finishing at 1% at the end of the fourth year. This fair value of this embedded derivative has been estimated at a nominal amount.

The Loan is secured by a first ranking interest in favor of Synergy Acquisitions Holding Ltd. (“Synergy”) on Sigma Brazil’s assets, rights, licenses, receivables, contracts (with flexibility to enter/terminate/amend offtake agreements) and a pledge of 100% of Sigma Lithium Holdings Inc’s share interest in Sigma Brazil. The security will rank first in respect to all existing and future indebtedness of Sigma, except in relation to permitted indebtedness of up to US$100 million; and the pledge of equipment financed by Development Bank of Minas Gerais (“BDMG”) in the amount of $3,084.

The lease liabilities are primarily related to land leases of surface properties owned by Miazga Participações S.A., (”Miazga”), a related party and Arqueana, a related party, (note 13) with the remaining land, apartments and houses, commercial rooms and vehicle leases with third parties.

The lease agreements have terms between 1 year to 12 years and the liability was measured at the present value of the lease payments discounted using interest rates with a weighted average rate of 8.37% (December 2022: 8,37%) which was determined to be the Company’s incremental borrowing rate. The continuity of the lease liabilities are presented in the table below:

Maturity analysis – contractual undiscounted cash flows

The Company has estimated its asset retirement obligation to be $6,919 at March 31, 2023 (December 31, 2022 - $6,547), representing the present value of estimated future rehabilitation costs to remediate environmental damages at March 31, 2023. The estimate is based on estimated future rehabilitation costs of $10,928, a nominal discount rate of 12,6% (December 31, 2022 12,6%), an inflation rate of 6.3% (December 31, 2022 – 4.0%), resulting in a real discount rate of 6.3% (December 31, 2022 – 6.3%).

Of the $6,919 of asset retirement obligation, $3,042 relates to the Xuxa Mine which is classified within property, plant and equipment with the remaining $3,877 relating to the Barreiro mine classified within exploration and evaluation assets.

The following table shows the continuity of warrants during the period:

⁽¹⁾ In February 2022, the Company received from A10 Advisory $2,345 upon the exercise of 532,860 warrants into 532,860 common shares at an exercise price of $4.40 per share.

The Company's activities expose it to a variety of financial risks: credit risk, liquidity risk and market risk (including interest rate risk, foreign currency risk and price risk).

The fair values of cash, accounts payable, and note payable approximate their carrying values due to the short-term to maturity of these financial instruments.

Credit risk

Credit risk is the risk of loss associated with a counterparty’s inability to fulfill its payment obligations. The Company’s credit risk is primarily attributable to receivables.

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company’s approach to managing liquidity is to ensure it will have sufficient liquidity to meet liabilities when due. To the extent the Company does not believe it has sufficient liquidity to meet obligations, it will consider securing additional equity or debt funding.

As of March 31, 2023, the carrying amount of financial liabilities, measured using the amortized cost method are described below. Their corresponding maturities are evidenced below:

Market risk

Market risk is the risk of loss that may arise from changes in market ‘factors such as interest rates and foreign exchange rates.

The Company has cash balances. The Company’s current policy is to invest surplus cash in savings accounts with a Canadian chartered bank with which it keeps its bank accounts. As of March 31, 2023, the Company has $92,852 as cash.

The Company’s functional and presentation currency is the Canadian dollar and certain purchases, and salaries are transacted in Canadian dollars. The Company also has significant balances in Brazilian Reais and United States dollars that are subject to foreign currency risk.

The Company had the following balances in the prescribed currencies:

The Company’s Board of Directors has adopted the Equity Incentive Plan. The Equity Incentive Plan received majority (and majority of disinterested) shareholder approval in accordance with the policies of the TSXV at the annual and special meeting of the Company’s shareholders held on June 28, 2019. The Equity Incentive Plan is available to (i) the directors of the Company, (ii) the officers and employees of the Company and its subsidiaries and (iii) designated service providers, who spend a significant amount of time and attention on the affairs and business of the Company or a subsidiary thereof (each, a “Participant”), all as selected by the Company’s Board of Directors or a committee appointed by the Company’s Board of Directors to administer the Equity Incentive Plan (the “Plan Administrators”).

⁽¹⁾ On September 8, 2021, the Board granted an aggregated 5,000,000 RSUs to the Co-CEOs of the Company (2,500,000 RSUs to each Co-CEOs). 5,000,000 of the RSUs granted to the Co-CEOs (being 2,500,000 RSUs granted to each Co-CEO) vested in four tranches upon the achievement of specified market capitalization targets as follows:

An additional aggregate 500,000 RSUs will vest to CEO upon approval by the Board of Directors of the plan to achieve a net zero carbon target and its subsequent successful execution.

These RSUs contain a market condition, and therefore the Company has used a Monte Carlo Simulation methodology to determine the grant date fair value of the RSUs which incorporated the following assumptions:

(Expressed in thousands of Canadian dollars, except per share amounts, and number of shares, unless otherwise indicated)

The expense for these RSUs have been valued based on the Company’s share price at the grant date.

⁽¹⁾ On April 5, 2022, the Compensation Committee, delegated by the Board, approved the grant of 50,000 fully vested RSUs to a key consultant of the Company.

⁽²⁾ On July 20, 2022, the Board approved the grant of 1,000,000 RSUs to the COO of the Company. These RSUs vest upon the achievement of specific operational goals (“milestones”). These RSUs contain certain non-market performance conditions and were valued using the Company’s share price on grant date. Such performance conditions relate to the achievement of the plant commissioning within a specific forecast, as well as the production of spodumene concentrate with detailed specification throughout a certain period. The Company considers that the likelihood of achievement of the milestones is probable, as result such RSUs have been fully accounted for and valued using the share price on the grant date.

⁽³⁾ On August 5, 2022, the Company entered into a consulting agreement with an individual, where a total amount of 250,000 RSUs were awarded, being 120,000 immediately vested RSUs, 65,000 RSUs vesting on October 10, 2023, and 65,000 RSUs vesting on October 10, 2024, all of which are subject to Board approval and confirmation by the Compensation Committee, delegated by the Board.

⁽⁴⁾ On October 28, 2022, the Compensation Committee, delegated by the Board, approved the grant of 1,332,332 fully vested RSUs to key employees, directors and designated service providers of the Company. These RSUs were previously accounted for and adjusted once the Compensation Committee approved the grant.

⁽⁵⁾ On December 1, 2022, the Company entered into compensation agreements with four of its directors, where They were awarded a total of 295,000 RSUs. Out of this total, 235,000 RSUs were subject to time-based vesting and 60,000 RSUs will vest on the achievement of an increase in the market capitalization of the Company to US$4 billion, conditional on the approval by the Compensation Committee, as delegated by the Board. Therefore, the Company has used a Monte Carlo Simulation methodology to determine the grant date fair value of the 60,000 RSUs which incorporated the following assumptions:

⁽⁶⁾ For the year ended December 31, 2022, the weighted average grant date fair value of RSUs amounted to $36.34 (December 31, 2021 - $7.55).

⁽⁷⁾ For 2,382,332 RSUs, upon receiving Board of Directors and Compensation Committee approval, the Company revised the earlier fair value estimate so that the amounts recognized for services received in respect of the grant are based on the grant date fair value. As 1,047,500 RSUs are subject to Board of Directors and Compensation Committee approval, the Company valued the RSUs based on fair value on December 31, 2022. Once a grant date under IFRS has been established, the Company will revise the earlier estimate so that the amounts recognized for services received in respect of the grant are based on the grant date fair value.

⁽⁸⁾ On March 22, 2023, the Compensation Committee, delegated by the Board, approved the grant of 140,333 fully vested RSUs to key employees, directors and designated service providers of the Company. These RSUs were previously accounted for and adjusted once the Compensation Committee approved the grant.

Total stock-based compensation for the three months ended March 31, 2023, in shareholders’ equity was $20,561 (year ended December 31, 2022 - $121,040), being $19,705 recorded as stock-based compensation expense (year ended December 31, 2022 - $110,108) and the remaining portion were recorded in exploration and evaluation assets was $340 (year ended 31, 2022 - $8,528) and property, plant and equipment was $516 (year ended December 31, 2022 - $2,404).

The facility agreement provides for the loan of an amount up to US$12 million (equivalent to $16 million). The facility agreement is to be made available upon utilization requests made by Tatooine to SMSA, specifying the amount to be utilized by Tatooine for the acquisition of each property and its corresponding expected costs and expenses.

At July 24, 2023 Sigma Lithium began trading its Brazilian Depositary Receipts (“BDR’s”) on B3, the Brazilian Stock Exchange. The listing was an initiative of the B3 exchange itself, in an effort to make the stock more accessible to Brazilian retail and institutional investors. The BDRs are unsponsored and count on B3 as depositary and Sigma has no awareness of the volume and prices traded. The unsponsored BDRs are not regulated by the Brazilian CVM.

At July 27, 2023 Sigma Brazil initiated its operations and shipped the first 31,500 tons, being 15,000 tons of Green Lithium and 16,500 tons of Green Tailings.

On July 28, 2023, the Company changed its Chief Financial Officer (“CFO”). Caio Araujo, who was hired on June 26, 2023 as Chief Controls Officer (“CCO”) replaced the former CFO, and the Senior Financial Controller, Raphael Dias, hired on July 5, 2023, replaced Mr. Araujo as the new CCO.
