The Corporation encourages Registered Shareholders and Non-Registered Shareholders who have duly appointed themselves as proxyholders to participate actively in the Meeting, to vote and ask questions.

Non-Registered Shareholders who have not appointed themselves as proxyholders may attend the Meeting as guests, by clicking "Guest" and completing the online form. **Guests will not be able to vote or ask questions at the Meeting.**

**It is important that you are connected to the internet at all times during the Meeting in order to vote when balloting commences.** The Corporation recommends that attendees log into the Meeting platform at least thirty minutes before the Meeting begins. Attendees are entirely responsible to ensure internet connectivity during the Meeting and that all internal network security protocols (such as firewalls or VPN connections) that may block access to the Meeting platform are disabled to allow the attendee to attend the Meeting. Attendees will also need to have the latest version of Chrome, Safari, Edge or Firefox. **Note Internet Explorer is not a supported browser**. Note that if connectivity is lost once the Meeting has commenced, there may be insufficient time to resolve the connectivity issue before voting polling is completed. Therefore, Shareholders should consider voting in advance or by proxy, so that all votes will be counted in the event of any technical difficulties.

**In order to participate online, Registered Shareholders must have a valid 15-digit Control Number and proxyholders must have received an email from Computershare Investor Services Inc.** ("**Computershare**") **containing an Invite Code.** 

Registered Shareholders who wish to appoint a proxyholder are required to complete, date and execute the form of proxy and submit to Computershare either in person, or by mail or courier, to 320 Bay Street, 14th Floor, Toronto, ON M5H 4A6, Canada, or via the internet at www.investorvote.com. The proxy must be deposited with Computershare by no later than 11:00 a.m. (Toronto time) on June 26, 2026, or if the Meeting is adjourned or postponed, not less than 48 hours, excluding Saturdays, Sundays and statutory holidays, before the commencement of such adjourned or postponed Meeting. If a Shareholder who has submitted a proxy attends the Meeting via the webcast and has accepted the terms and conditions when entering the Meeting online, any votes cast by such Shareholder on a ballot will be counted and the submitted proxy will be disregarded. **Registered Shareholders must carefully follow the instructions contained in the section "Proxy Information" of the Circular.**

After submitting the form of proxy, as an additional and required step, Registered Shareholders will need to register their proxyholders with Computershare at http://www.computershare.com/SigmaLithium no later than 11:00 a.m. (Toronto time) on June 26, 2026 and provide Computershare with their proxyholder's contact information at the "<u>Appointee Information</u>" section on the website indicated above, so that Computershare may provide the proxyholder with an Invite Code via email.

An intermediary holding common shares on behalf of a Non-Registered Shareholder has the right to appoint the Non-Registered Shareholder as a proxyholder to attend and act on their behalf at the Meeting. After submitting the Non-Registered Shareholder voting instruction form, the intermediary must register the Non-Registered Shareholder with Computershare at <u>http://www.computershare.com/SigmaLithium</u> to receive the Invite Code that will enable the Non-Registered Shareholder to participate actively at the Meeting, voting, and asking questions. **Non-Registered Shareholders should carefully follow the instructions contained in the section "Proxy Information" of the Circular.**

**FAILURE TO REGISTER THE PROXYHOLDER WITH COMPUTERSHARE WILL RESULT IN THE PROXYHOLDER NOT RECEIVING AN INVITE CODE TO PARTICIPATE IN THE MEETING. WITHOUT AN INVITE CODE, PROXYHOLDERS WILL NOT BE ABLE TO VOTE AT THE MEETING.**

Shareholders are reminded to review the Circular before voting.

DATED at São Paulo, Brazil this 1<sup>st</sup> day of June, 2026.

**BY ORDER OF THE BOARD OF<br> DIRECTORS of Sigma Lithium Corporation**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(signed)

Pursuant to National Instrument 54-101 – *Communication with Beneficial Owners of Securities of a Reporting Issuer* ("**NI 54-101**"), arrangements have been made with clearing agencies, brokerage houses and other financial intermediaries to forward proxy solicitation material to the beneficial owners of Common Shares.

![](sgml202606026k_002.jpg)

**Appointment of Proxyholder – Step I**

Registered Shareholders or Intermediaries will receive a paper copy of a form of proxy ("**Form of Proxy**") jointly with the Meeting Materials and Non-Registered Shareholder will receive a voting instruction form to be provided to the Intermediary jointly with the Meeting Materials.

A Registered Shareholder not available to attend the Meeting, or an Intermediary holding Common Shares on behalf of a Non-Registered Shareholder can appoint a person, who need not be a shareholder, to attend and act on their behalf at the Meeting (a "**Proxyholder**"). They may vote and indicate a Proxyholder by submitting to Computershare the Form of Proxy in one of the following forms:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o in person, by delivering the
completed, dated and signed Form of Proxy to Computershare at 320 Bay Street, 14th Floor, Toronto, ON M5H 4A6, Canada ,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o by mail or courier, submitting
the completed, dated and signed Form of Proxy to Computershare at 320 Bay Street, 14th Floor, Toronto, ON M5H 4A6, Canada ,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o via the internet at www.investorvote.com ,
using the 15-digit Control Number located at the bottom of their Form of Proxy, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o by telephone at 1-866-732-VOTE (8683) Toll Free,
using the 15-digit Control Number located at the bottom of their Form of Proxy.

The Form of Proxy must be deposited with Computershare by no later than 11:00 a.m. (Toronto time) on June 26, 2026, or if the Meeting is adjourned or postponed, not less than 48 hours, excluding Saturdays, Sundays and statutory holidays, before the commencement of such adjourned or postponed Meeting.

Voting by mail or by Internet are the only methods by which a Shareholder may appoint a person as a Proxyholder other than the Management Nominees (as defined below).

If a Registered Shareholder has submitted to Computershare the Form of Proxy and then decides to attend the Meeting via the webcast, when entering the meeting online the Registered Shareholder will need to accept the "Terms and Conditions" and any votes cast by such Registered Shareholder on a ballot will be counted and the submitted Form of Proxy will be disregarded.

**Registration of the Proxyholder with Computershare – Step II**

After submitting the Form of Proxy, as an additional and required step, Registered Shareholders or Intermediaries holding Common Shares on behalf of a Non-Registered Shareholder will need to register their Proxyholder with Computershare at http://www.computershare.com/SigmaLithium no later than 11:00 a.m. (Toronto time) on June 26, 2026 and provide Computershare with their Proxyholder's contact information at the "Appointee Information" section on the website indicated above, so that Computershare may provide the Proxyholder with an Invite Code via email.

*FAILURE TO REGISTER THE PROXYHOLDER WITH COMPUTERSHARE WILL RESULT IN THE PROXYHOLDER NOT RECEIVING AN INVITE CODE TO PARTICIPATE IN THE MEETING. WITHOUT AN INVITE CODE, PROXYHOLDERS WILL NOT BE ABLE TO VOTE AT THE MEETING.*

**Completion of the Form of Proxy** 

The Form of Proxy affords Registered Shareholders or Intermediaries an opportunity to specify that the Common Shares registered in their name shall be voted for or against or withheld from voting in respect of certain matters as specified in the Notice of Meeting. The persons named in the Form of Proxy are directors of the Corporation (the "**Management Nominees**").

**A REGISTERED SHAREHOLDER OR AN INTERMEDIARY HOLDING COMMON SHARES ON BEHALF OF A NON-REGISTERED SHAREHOLDER HAS THE RIGHT TO APPOINT A PERSON, WHO NEED NOT BE A SHAREHOLDER, TO ATTEND AND ACT ON THEIR BEHALF AT THE MEETING, IN THE PLACE OF THE PERSONS DESIGNATED IN THE FORM OF PROXY FURNISHED BY THE CORPORATION. TO EXERCISE THIS RIGHT, THE REGISTERED SHAREHOLDER OR INTERMEDIARY SHOULD STRIKE OUT THE NAMES OF THE PERSONS NAMED IN THE FORM OF PROXY AND INSERT THE NAME OF THEIR PROXYHOLDER IN THE BLANK SPACE PROVIDED, OR SUBMIT ANOTHER APPROPRIATE PROXY.**

---

![](sgml202606026k_002.jpg)

A Form of Proxy must be dated and signed by the Registered Shareholder or by their attorney authorized in writing or by the Intermediary. In the case of a Shareholder that is a corporation, the Form of Proxy must be executed under its corporate seal or signed by a duly authorized officer or attorney for the corporation with proof of authority accompanying the Form of Proxy.

**Revocation of a Submitted Form of Proxy**

A Registered Shareholder or Intermediary who has submitted a Form of Proxy may revoke it by instrument in writing executed by the Registered Shareholder or Intermediary or his or her attorney authorized in writing, or, if the Shareholder is a corporation, under its corporate seal and executed by a director, officer or attorney thereof duly authorized, and deposited either with the Corporation at its offices as aforesaid at any time prior to the close of business on the second last business day preceding the day of the Meeting, or any adjournment thereof, at which the proxy is to be used, or with the Chairman of the Meeting prior to the commencement of the Meeting on the day of the Meeting, and upon such deposit the previous proxy is revoked.

**Exercise of Discretion by Proxyholders**

A Registered Shareholder or Intermediary may indicate the manner in which the persons named in the Form of Proxy are to vote with respect to any matter by checking the appropriate space. On any poll, those persons will vote for or against (or withhold from voting) the Common Shares in respect of which they are appointed in accordance with the directions, if any, given in the Form of Proxy. If the Shareholder or Intermediary wishes to confer a discretionary authority with respect to any matter, the space should be left blank. **IN SUCH INSTANCE, THE PERSONS NAMED IN THE ENCLOSED FORM OF PROXY INTEND TO VOTE THE COMMON SHARES REPRESENTED BY THE PROXY IN FAVOUR OF THE MOTION.**

The Form of Proxy confers discretionary authority upon the persons named therein with respect to amendments or variations to matters identified in the Notice of Meeting and with respect to other matters which may properly come before the Meeting. At the time of printing of this Circular, management of the Corporation knows of no such amendment, variation or other matter. However, if any other matters which are not now known to management should properly come before the Meeting, the proxies in favour of Management Nominees will be voted on such matters in accordance with the best judgment of the Management Nominees.

**Advice to Non-Registered Shareholders**

Further to the details above under the heading "***Attending and Voting at the Meeting***", only Registered Shareholders, or the persons they appoint as their proxies, are permitted to attend and vote at the Meeting. However, in many cases, Common Shares beneficially owned by a Non-Registered Shareholder are registered either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) in the name of an Intermediary
that the Non-Registered Shareholder deals with in respect of the Common Shares, such as, among others, banks, trust companies, securities
dealers or brokers and trustees or administrators of self-administered registered savings plans, registered retirement income funds, registered
education savings plans and similar plans; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) in the name of a clearing agency
(such as CDS Clearing and Depository Services Inc.) of which the Intermediary is a participant.

In accordance with the requirements of NI 54-101, the Corporation has distributed copies of the Notice of Meeting, this Circular, the Form of Proxy or a voting instruction form and a supplemental mailing card (collectively, the "**Meeting Materials**") to the clearing agencies and Intermediaries for onward distribution to Non-Registered Shareholders.

Intermediaries are required to forward the Meeting Materials to Non-Registered Shareholders unless a Non-Registered Shareholder has waived the right to receive them. Intermediaries will generally use service companies (such as Broadridge Financial Solutions, Inc.) to forward the Meeting Materials to Non-Registered Shareholders. Generally, a Non-Registered Shareholder who has not waived the right to receive Meeting Materials will receive either a voting instruction form or, less frequently, a Form of Proxy. The purpose of these forms is to permit Non-Registered Shareholders to direct the voting of the Common Shares they beneficially own. Non-Registered Shareholders should follow the procedures set out below, depending on the type of form they receive:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) *Voting Instruction Form*.
In most cases, a Non-Registered Shareholder will receive, as part of

the Meeting Materials, a voting instruction form. If the Non-Registered Shareholders does not wish to attend and vote at the Meeting in person (or have another person attend and vote on the Non-Registered Shareholder's behalf) but wishes to direct the voting of the Common Shares they beneficially own, the voting instruction form must be submitted by mail, telephone or over the internet in accordance with the directions on the form. If a Non-Registered Shareholder wishes to attend and vote at the Meeting in person (or have another person attend and vote on the Non-Registered Shareholder's behalf), the Non-Registered Shareholder must complete, sign and return the voting instruction form in accordance with the directions provided and a form of proxy giving the right to attend and vote will be forwarded to the Non-Registered Shareholder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) *Form of Proxy*. Less frequently,
a Non-Registered Shareholder will receive, as part of the Meeting Materials, a Form of Proxy that has already been signed by the Intermediary
(typically by facsimile, stamped signature) which is restricted as to the number of Common Shares beneficially owned by the Non-Registered
Shareholder, but which is otherwise uncompleted. If the Non-Registered Shareholder does not wish to attend and vote at the Meeting in
person (or have another person attend and vote on the Non-Registered Shareholder's behalf) but wishes to direct the voting of the
Common Shares they beneficially own, the Non-Registered Shareholder must complete the Form of Proxy and submit it to Computershare as
described above. If a Non-Registered Shareholder wishes to attend and vote at the Meeting in person (or have another person attend and
vote on the Non-Registered Shareholder's behalf), the Non-Registered Shareholder must strike out the persons named in the proxy
and insert the Non-Registered Shareholder's (or such other person's) name in the blank space provided.

In either case, Non-Registered Shareholders should carefully follow the instructions of their Intermediaries, including those regarding when and where the Form of Proxy or the voting instruction form is to be delivered.

A Non-Registered Shareholder may revoke a voting instruction form or a waiver of the right to receive Meeting Materials and to vote given to an Intermediary at any time by written notice to the Intermediary, except that an Intermediary is not required to act on a revocation of a voting instruction form or of a waiver of the right to receive materials and to vote that is not received by the Intermediary at least seven days prior to the Meeting.

A Non-Registered Shareholder may fall into two categories – those who object to their identity being made known to the issuers of the securities which they own ("**Objecting Beneficial Owners**") and those who do not object to their identity being made known to the issuers of the securities which they own under NI 54-101 ("**Non-Objecting Beneficial Owners**"). The Corporation is not sending Meeting Materials directly to Non-Objecting Beneficial Owners, but rather is relying on Intermediaries and agents to send the Meeting Materials. The Corporation also intends to pay for Intermediaries to deliver the Meeting Materials to Objecting Beneficial Owners.

If you have any questions respecting the voting of Common Shares held through an Intermediary, please contact that Intermediary for assistance.

The Corporation is authorized to issue an unlimited number of Common Shares. As at the date hereof, there are **112,064,646** fully paid and non-assessable Common Shares issued and outstanding.

However, a person appointed under a Form of Proxy will be entitled to vote the Common Shares represented by that form only if it is effectively delivered in the manner set out under the heading "***Proxy Information***" above.

● Ana Cristina Cabral (the Corporation's Current Co-Chair and Chief Executive Officer); Felipe Resende Peres (the Corporation's Current Chief Financial Officer); Rogério Marchini (the Corporation's Former Chief Financial Officer); (together, the "**Named Executive Officers** "); and

● the directors of the Corporation that are not Named Executive Officers.

**Compensation Discussion and Analysis**

*Introduction*

The purpose of this compensation discussion and analysis is to describe the significant elements of the Corporation's executive compensation program, with particular emphasis on the process for determining compensation payable to the Named Executive Officers, and to the directors of the Corporation.

While there is no present intention to make any material changes to the executive compensation program described in this section, the Board may review the executive compensation program and, if determined appropriate, may make changes they consider appropriate.

*Compensation Philosophy and Objectives*

The executive compensation program is designed to attract and retain qualified and experienced executives who will contribute to the success of the Corporation. The Corporation designed its executive compensation program for senior executive officers to encourage, compensate and reward employees on the basis of individual and corporate performance, and to align the interests of executive officers with the interest of Shareholders. Senior executive officers will be motivated through the program to enhance long-term Shareholder value.

*Elements of Compensation*

The Board, acting on the recommendation of the People & Governance Committee, has implemented a compensation structure intended to align the interests of the executive officers with those of the Shareholders. The Corporation relies primarily on discussions between the People & Governance Committee and the Board to determine compensation. The executive compensation program consists of two components: (i) base compensation, and (ii) a long-term compensation component in the form of Awards under the equity incentive plan approved by Shareholders at the annual and special meeting of the Corporation held on June 30, 2023 (the "**Equity Incentive Plan**"). Both components are determined and administered by the Board.

The Corporation does not offer a pension or deferred compensation plan.

<u>Base Compensation</u>

Base compensation for the senior executive officers is set annually, having regard to the individual's job responsibilities, contribution, experience and proven or expected performance, as well as to market conditions and the Corporation's cash position. In setting base compensation levels, consideration is given to such factors as level of responsibility, experience and expertise. Subjective factors such as leadership, commitment and attitude are also considered. Base salaries are set with the goal of being competitive with corporations of a comparable size and at the same stage of development, thereby enabling the Corporation to compete for and retain executive officers critical to the Corporation's long-term success.

<u>Awards and Other Long-Term Compensation</u>

To provide a long-term component to the executive compensation program, certain executive officers, directors, consultants, and employees have been and will be granted Options and/or RSUs under the Equity Incentive Plan. The maximization of shareholder value is encouraged by granting long-term equity incentives in the form of Options and/or RSUs under the Equity Incentive Plan. Consideration is given to distributing long-term equity incentives amongst the various organizational levels including directors, officers, consultants, and employees. The Chief Executive Officer makes recommendations for the Chief Financial Officer and other key employees. These recommendations take into account factors such as Awards made in previous years, the number of long- term equity incentives outstanding per individual and the level of responsibility.

As demonstrated above, the market price of the Common Shares outperformed the S&P/TSX Venture Composite Index over the applicable period. The Corporation's share performance over the applicable period was influenced by the state of lithium markets and prices. The trend in overall compensation paid to the Corporation's executive officers over the past three years has generally reflected the

performance of the market price of the Common Shares or the S&P/TSX Venture Composite Index. The value of long-term incentive compensation in the form of Awards is influenced by the Common Share price performance.

*Share-Based and Option-Based Awards*

To provide a long-term component to the executive compensation program, certain executive officers, directors and consultants have been and will be granted Options and/or RSUs under the Equity Incentive Plan. Individual grants are determined by an assessment of an individual's current and expected future performance, level of responsibilities and the importance of the position and contribution to the Corporation. In addition to these assessments, previous grants are considered when the People & Governance Committee and/or the Board analyzes the possibility of new grants to eligible Participants under the Equity Incentive Plan. Subject to adjustment in certain circumstances as discussed below, the Equity Incentive Plan (together with all other security-based compensation plans of the Corporation) authorizes a maximum of 18,120,878 Common Shares (being 18% of the issued and outstanding Common Shares at the time of approval of the Equity Incentive Plan) that are issuable to Participants and that may be subject to Awards.

*Compensation Governance*

The People & Governance Committee (formerly, the Corporate Governance, Nomination and Compensation Committee) of the Board reviews and makes recommendations to the Board concerning the compensation of the Corporation's directors, officers and employees, which includes the review of the Corporation's executive compensation and other human resource philosophies and policies, the review and administration of the Corporation's bonuses and Awards, the review of and recommendations regarding the performance of the Chief Executive Officer and preparing and submitting a report for inclusion in annual continuous disclosure documents as required. The current members of the People & Governance Committee are Marcelo Paiva (Chair, non-independent), Kátia Abreu (independent) and Junaid Jafar (independent). See "***Election of Directors – Director Nominees***".

Since compensation practices can have unintended risk consequences, the Board reviews its compensation policies to identify any practice that might encourage an employee to expose the Corporation to unacceptable risks. It is not believed that the compensation program encourages excessive or inappropriate risk taking as: (i) employees receive both fixed and variable compensation, and the fixed (salary) portion provides a steady income regardless of the stock value, which allows employees to focus on the Corporation's business; and (ii) the long-term equity incentives encourage a long-term perspective due to the vesting provisions of the Awards. There is no current intention to implement a policy which prohibits any Named Executive Officer or director from purchasing financial instruments designed to hedge or offset a decrease in market value of equity securities granted as compensation.

Each committee member has the skills and experience to enable the People and Governance Committee to make decisions on the suitability of the Corporation's compensation policies and practices. The Corporation believes that the members of the People & Governance Committee collectively have the knowledge, experience and background required to fulfill their mandate. Such knowledge, experience and background enable them to make decisions regarding the sustainability of the Corporation's compensation policies and practices.

The Corporation did not retain a compensation consultant or advisor since the beginning of the most recently completed financial year.

A summary of the corporate governance practices of the Corporation can be found under the heading "***Corporate Governance Practices***".

**Summary Compensation Table** 

The following table provides information for the three most recently completed financial years of the Corporation ended December 31, 2025, regarding all compensation paid to or earned by the Named Executive Officers.

(2) The maximum number of Common Shares that are issuable to Participants that may be subject to Awards under
the Equity Incentive Plan and all other security-based compensation plans of the Corporation is 18,120,878 (being 18% of the issued and
outstanding Common Shares at the time of establishing the Equity Incentive Plan).

***Summary of Equity Incentive Plan***

The Equity Incentive Plan is available to *bona fide* (i) directors of the Corporation, (ii) officers, consultants and employees of the Corporation and its subsidiaries and (iii) designated service providers who spend a significant amount of time and attention on the affairs and business of the Corporation or a subsidiary thereof (each, a "**Participant**"), all as selected by the Board or a committee appointed by the Board to administer the Equity Incentive Plan (the "**Plan Administrators**").

The objective of the Equity Incentive Plan is to encourage increased long term equity participation in the Corporation by Participants. The Equity Incentive Plan is intended to facilitate long term ownership of Common Shares by Participants and to provide Participants with additional incentives by increasing their interest, as owners, in the Corporation. As well, it is believed that the Equity Incentive Plan will encourage Participants to remain with the Corporation, and will also attract new employees to the Corporation.

*Awards*

Awards granted under the Equity Incentive Plan may consist of options to acquire Common Shares ("**Options**") and restricted share units ("**RSUs**", and together with Options, "**Awards**"). Each Award will be subject to the terms and conditions set forth in the Equity Incentive Plan and to those other terms and conditions specified by the Plan Administrators and memorialized in a written award agreement. Previous grants of Awards will be taken into account as part of the process when considering new grants, as well as the performance of the Corporation and its subsidiaries and the individual performance of the Participant in question.

*Shares Subject to the Incentive Plan; Outstanding Awards*

Subject to adjustment in certain circumstances as discussed below, the Equity Incentive Plan (together with all other security-based compensation plans of the Corporation) authorizes a maximum of 18,120,878 Common Shares (being 18% of the issued and outstanding Common Shares at the time of approval of the Equity Incentive Plan) that are issuable to Participants and that may be subject to Awards. The maximum number of Common Shares under all combined security-based compensation plans of the Corporation will not change.

Unless the Corporation has obtained the necessary approvals required by the TSXV, within any one year period, no Participant may be the grantee of Awards with respect to more than 5% of the then issued and outstanding Shares, unless disinterested shareholder approval is obtained. In addition, (i) the number of Shares issuable to Insiders (as a group), at any time, pursuant to the Plan and any other Security Based Compensation Plan adopted by the Corporation, cannot exceed 10% of the then issued and outstanding Shares, unless disinterested shareholder approval is obtained; (ii) the number of

---

![](sgml202606026k_002.jpg)

Shares issued to Insiders (as a group), within any one year period, under the Plan and any other Security Based Compensation Plan adopted by the Corporation cannot exceed 10% of the then issued and outstanding Shares, unless disinterested shareholder approval is obtained; (iii) the number of Shares issued to any one Service Provider, within any one year period, under the Plan and any other Security Based Compensation Plan adopted by the Corporation cannot exceed 2% of the then issued and outstanding Shares; (iv) the number of Shares issued to all Participants retained to provide Investor Relations Activities (as defined in the policies of the TSXV) to the Corporation, within any one year period, under the Plan and any other Security Based Compensation Plan adopted by the Corporation cannot exceed 2% of the then issued and outstanding Shares; and (v) the number of Shares issued to any one Consultant, within any one year period, under the Plan and any other Security Based Compensation Plan adopted by the Corporation cannot exceed 2% of the then issued and outstanding Shares. Participants retained to provide Investor Relations Activities shall only be eligible to be granted Awards in the form of Options.

If, and to the extent, Awards granted under the Equity Incentive Plan expire, terminate, are cancelled, or are forfeited for any reason without having been exercised in full, the Common Shares associated with those Awards will again become available for grant under the Equity Incentive Plan.

In the event of any recapitalization, reorganization, arrangement, amalgamation, split or combination, distribution or other similar event or transaction, or any other change in the capital of the Corporation affecting the Common Shares, substitutions or adjustments will be made by the Plan Administrators in their discretion to: (i) the aggregate number, class and/or issuer of the securities reserved for issuance under the Equity Incentive Plan (including, but not limited to, with respect to the aggregate number of Awards any one Participant may be granted during any period); (ii) the number, class and/or issuer of securities subject to outstanding Awards; and (iii) the exercise price of outstanding Awards, in each case in a manner that reflects equitably the effects of such event or transaction.

*Administration*

The Equity Incentive Plan is administered and interpreted by the Plan Administrators. The Plan Administrators have full authority to grant Awards under the Equity Incentive Plan and determine the terms of such Awards, including the persons to whom Awards are to be granted, the type and number of Awards to be granted and the number of Common Shares to be covered by each Award. The Plan Administrators also have full authority to specify the time(s) at which Awards will be exercisable or settled.

*Eligibility*

Directors, officers and employees of the Corporation and its subsidiaries and designated service providers who spend a significant amount of time and attention on the affairs and business of the Corporation or a subsidiary thereof are eligible to participate in the Incentive Plan.

*Options*

The Equity Incentive Plan provides that the Plan Administrators may grant Options. Any Options granted under the Equity Incentive Plan will have a maximum term of ten years and will be exercisable at a price not less than the Fair Market Value of a Common Share. "**Fair Market Value**" for purposes of the Equity Incentive Plan means, as of any date: (i) if the Common Shares are not then publicly traded, the fair market value of a Common Share on the day immediately preceding such date, as determined by the Plan Administrators in their sole and absolute discretion; or (ii) if the Common Shares are publicly traded, the volume weighted average trading price of the Common Shares for the ten trading days immediately preceding such date on the TSXV or the principal securities exchange on which the majority of the trading in the Common Shares occurs (provided that if such volume weighted average trading price is less than the Discounted Market Price (as such term is defined in the policies of the TSXV) as of such date, the Fair Market Value shall be the Discounted Market Price as of such date)) or, if the Common Shares are not then listed and posted for trading on the TSXV or any securities exchange, but are traded in the over-the-counter market, the volume weighted average trading price of the Common Shares for the ten trading days immediately preceding such date; provided that if there has not been at least five trading days in such period in which Common Shares have traded then for purposes of item (ii) the simple average of the mid points between the bid and ask prices for such ten trading days for trading days in which there have been no trades and the volume weighted average trading prices for trading days in which there have been trades are to be used.

Initially, Options will vest, subject to the right of the Plan Administrators to determine at the time of grant that a particular Option will be exercisable in whole or in part on a different date and to determine at any time after the time of grant that a particular Option will be exercisable in whole or in part on an earlier date for any reason: (i) on and after the first anniversary of the date of grant, as to 20% of such Options; (ii) on and after the second anniversary of the date of grant, as to a further 20% of such Options; (iii) on and after the third anniversary of the date of grant, as to a further 20% of such Options; (iv) on and after the fourth anniversary of the date of grant, as to a further 20% of such Options; and (v) on and after the fifth anniversary of the date of grant, as to the remaining 20% of such Options. In addition, vesting of Options may be subject to performance tests at the discretion of the Plan Administrators. The vesting terms set out in the Equity Incentive Plan will supersede any other vesting terms previously proposed by the Corporation.

Notwithstanding the foregoing, the Equity Incentive Plan provides that in the event that the term of an Option expires during a "blackout period" imposed by the Corporation, the Option will expire on the date (the "**Blackout Expiration Date**") that is ten business days following the end of the blackout period. The Blackout Expiration Date will not be subject to the discretion of the Plan Administrators.

*Restricted Share Units*

The Equity Incentive Plan provides that the Plan Administrators may grant Awards of RSUs. An RSU is a contractual promise to issue Common Shares and/or cash in an amount equal to the Fair Market Value of the Common Shares subject to the Award, at a specified future date. Each RSU will initially have a value equal to the Fair Market Value of a Common Share when the subject Award is made. Each RSU will represent the right to receive from the Corporation, after fulfillment of any applicable conditions, a distribution from the Corporation of either (i) one Common Share, or (ii) an amount in cash equal to the Fair Market Value of one Common Share on the date of distribution. Any RSUs under the Equity Incentive Plan will have a maximum term of ten years. Initially, RSUs will vest on and after the third anniversary of the date of grant, subject to the right of the Plan Administrators to determine at the time of grant that a particular RSU will be exercisable in whole or in part on a different date and to determine at any time after the time of grant that a particular RSU will be exercisable in whole or in part on an earlier date for any reason. In addition, vesting of RSUs may be subject to performance tests at the discretion of the Plan Administrators.

An Award of RSUs may be settled in Common Shares, cash, or in any combination of Common Shares and cash, at the sole discretion of the Plan Administrators when the subject Award is made.

Participants retained to provide Investor Relations Activities shall not be eligible to be granted RSUs.

*Effects of Termination of Service*

Unless otherwise permitted by the Board:

<u>Death</u>: If a Participant's service terminates by reason of death, any Option or RSU held by such Participant will be immediately fully vested and exercisable and will only be exercisable for a period ending on the earlier of the applicable expiry date and 12 months following the date of death. In addition, exercisability of any Option or RSU which becomes vested as a result of the early vesting described in the preceding sentence will be conditional upon the Participant's estate entering into an arrangement under which the Common Shares issued upon exercise of such Option or RSU, as applicable, may not be sold prior to the date on which the corresponding Option or RSU, as the case may be, would otherwise have vested in the ordinary course.

<u>Retirement</u>: In the event of the retirement of a Participant from employment, any Option or RSU held by such Participant will thereafter continue to vest and become exercisable in accordance with its terms and will only be exercisable for a period ending on the earlier of the applicable expiry date and 12 months following the date of retirement (or 30 days after the date such Participant ceases to be retired and is employed by a competitor of the Corporation).

<u>Resignation/Natural Termination</u>: In the event of the resignation of a Participant, or a Participant's contract as a Service Provider (as defined in the Equity Incentive Plan) terminates at its normal termination date, any unvested Option or RSU held by such Participant will expire and terminate on the date of resignation or the normal termination date in the case of a Service Provider, as applicable, and any vested Option or RSU will only remain exercisable for a period ending on the earlier of the applicable expiry date and 30 days following the date of resignation or the normal termination date, as applicable.

<u>Disability</u>: If a Participant's service terminates by reason of disability, any Option or RSU held by such Participant may thereafter be exercised by the Participant to the extent it was exercisable at the time of termination, for a period ending on the earlier of the applicable expiry date and 12 months following the date of termination by reason of disability. In addition, exercisability of any Option or RSU which becomes vested as a result of the early vesting described in the preceding sentence will be conditional upon the Participant or the Participant's legal representative, as applicable, entering into an arrangement under which the Common Shares issued upon exercise of such Option or RSU, as applicable, may not be sold prior to the date on which the corresponding Option or RSU, as the case may be, would otherwise have vested in the ordinary course.

<u>Termination Without Cause</u>: If a Participant's service as an employee is terminated without cause (as defined in the Equity Incentive Plan), or a Participant's contract as a Service Provider is terminated before its normal termination date without cause:

&nbsp;&nbsp;&nbsp;&nbsp;(a) any vested Option or RSU will
only remain exercisable for a period ending on the earlier of the applicable expiry date and six months following the date of termination;

&nbsp;&nbsp;&nbsp;&nbsp;(b) such number of unvested RSUs
held by such Participant as determined by the formula below will be immediately fully vested and exercisable and will only be exercisable
by the Participant for a period ending on the earlier of the applicable expiry date and six months following the date of termination:

| &nbsp;&nbsp;Number of unvested Restricted Share Units accelerated | &nbsp;&nbsp;= | &nbsp;&nbsp;Number of Restricted Share Units that would vest on the next vesting date following the date of termination | &nbsp;&nbsp;x | &nbsp;&nbsp;Number of months from the last vesting date (or, if the next vesting date is the first vesting date, from the date of grant of the RSUs) to the next vesting date |

---

&nbsp;&nbsp;&nbsp;&nbsp;(c) such number of unvested Options
held by such Participant as determined by the formula below will be immediately fully vested and exercisable and will only be exercisable
by the Participant for a period ending on the earlier of the applicable expiry date and six months following the date of termination:

---

| | | | | |
|:---|:---|:---|:---|:---|
| &nbsp;&nbsp;Number of unvested Options accelerated | &nbsp;&nbsp;= | &nbsp;&nbsp;Total number of unvested Options | &nbsp;&nbsp;x | &nbsp;&nbsp;Number of months from the date of grant of the Options to the date of termination |

---

<u>Termination With Cause</u>: If a Participant's service is terminated for cause, or a Participant's contract as a Service Provider is terminated before its normal termination date for cause: (i) any Option or RSU held by the Participant, whether vested or unvested, will immediately and automatically expire as of the date of such termination, and (ii) any Common Shares for which the Corporation has not yet delivered share certificates will be immediately and automatically forfeited and, in the case of Options, the Corporation will refund to the Participant the exercise price paid for such Common Shares, if any.

<u>Ceasing to Hold Office</u>: In the event that a Participant who is not an employee or Service Provider ceases to hold office as a director: (i) if it was the Participant's decision to cease to hold office, the provisions above related to resignation will apply; and (ii) otherwise, the provisions above related to termination without cause will apply.

*Assignability*

Except as may otherwise be specifically determined by the Plan Administrators with respect to a particular Award, Awards will not be assignable or transferrable by a Participant, other than by will or by the laws of descent or distribution.

*Amendment and Termination of the Equity Incentive Plan*

The Plan Administrators have the ability, in their sole discretion, to amend, suspend or terminate the Equity Incentive Plan; provided that no such amendment, suspension, or termination may be made without obtaining any required approval of any regulatory authority or stock exchange or materially prejudice the rights of any holder under any Award.

**INDEBTEDNESS OF DIRECTORS AND OFFICERS**

No director or executive officer of the Corporation, nor any of their associates or affiliates, nor any employee of the Corporation is or has been indebted to the Corporation since the beginning of the most recently completed fiscal year of the Corporation, nor is, or at any time since the beginning of the most recently completed fiscal year of the Corporation has, any indebtedness of any such person been the subject of a guarantee, support agreement, letter of credit or other similar arrangement or understanding provided by the Corporation or any of its subsidiaries.

**INTEREST OF INFORMED PERSONS IN MATERIAL TRANSACTIONS**

Other than as disclosed in this Circular or in the Corporation's Management Discussion and Analysis for the year ended December 31, 2025, a copy of which has been filed on the SEDAR+ and is available under the Corporation's profile at www.sedarplus.ca, there are no material interests, direct or indirect, of directors, executive officers of the Corporation or any person or company that beneficially owns, or controls or directs, directly or indirectly, more than 10% of the outstanding Common Shares or any known associate or affiliate of such persons, in any transaction since the commencement of the Corporation's most recently completed financial year.

**INTERESTS OF CERTAIN PERSONS AND COMPANIES IN MATTERS TO BE ACTED UPON**

Other than as disclosed in this Circular, management of the Corporation is not aware of any material interest of any director or nominee for director or senior officer or anyone who has held office as such since the beginning of the Corporation's last financial year or of any associate or affiliate of any of the foregoing in any matter to be acted on at the Meeting.

**CORPORATE GOVERNANCE PRACTICES**

In accordance with National Instrument 58-101 *Disclosure of Corporate Governance Practices* ("**NI 58-101**") and National Policy 58-201 *Corporate Governance Guidelines* ("**NP 58-201**"), issuers are to disclose the corporate governance practices that they have adopted. NP 58-201 provides guidance on corporate governance practices. The Corporation is also subject to National Instrument 52-110 *Audit Committees* ("**NI 52-110**"), which has been adopted in each of the Canadian provinces and territories and which prescribes certain requirements in relation to audit committees.

The Board is responsible for the governance of the Corporation. The Board and the Corporation's management consider good corporate governance to be central to the effective and efficient operation of the Corporation. Below is a discussion of the Corporation's approach to corporate governance.

**Board of Directors**

The Board is currently composed of five directors, being Ana Cristina Cabral (Co-Chair), Marcelo Paiva (Co-Chair), Junaid Jafar, Alexandre Rodrigues Cabral, and Kátia Abreu. Three directors, being Junaid Jafar, Alexandre Rodrigues Cabral, and Kátia Abreu, are independent for the purposes of NI 58-101. Ana Cristina Cabral (as Chief Executive Officer) is not independent. Marcelo Paiva is not independent as a result of him being portfolio manager of A10 Fund (which owns more than 10% of the outstanding Common Shares) and a Managing Partner of A10 Investimentos. One of the directors, Kátia Abreu, participates on the board of directors of other reporting issuer, JBS Inc.

The Board exercises its independent supervision over the Corporation's management through a combination of formal meetings of the Board as well as informal discussions amongst the Board members. The independent directors also hold scheduled meetings at which non-independent directors and members of management are not in attendance. Where matters arise at Board meetings which require decision making and evaluation that is independent of management and interested directors, the meeting breaks into an *in-camera* session among the independent and disinterested directors. The Corporation believes these practices encourage independent director leadership.

The attendance record of each director for all Board and Committee meetings held during the fiscal year ended December 31, 2025, while the relevant director was on the Board is as follows:

In establishing its corporate governance practices, the Board has been guided by applicable Canadian securities legislation and the guidelines of the TSXV for effective corporate governance, including NP 58-201. The Board is committed to a high standard of corporate governance practices. The Board believes that this commitment is not only in the best interests of its Shareholders, but that it also promotes effective decision making at the Board level.

The Corporation has adopted a Code of Business Conduct and Ethics that applies to all directors, officers, employees and consultants of the Corporation and its subsidiaries. A copy of the Code of Business Conduct and Ethics may be found on SEDAR+ at www.sedarplus.ca.

**Note**:

&nbsp;&nbsp;&nbsp;&nbsp;(1) The composition of the committees
is shown as at the date hereof.

 

*Audit, Finance and Risk Committee*

For a description of the Audit, Finance and Risk Committee, see "***Audit, Finance and Risk Committee***" herein.

*People & Governance Committee*

The People & Governance Committee reviews and makes recommendations to the Board concerning the compensation of the Corporation's directors, officers and employees, which includes the review of the Corporation's executive compensation and other human resource philosophies and policies, the review and administration of the Corporation's bonuses, stock options and any share purchase plan, the review of and recommendations regarding the performance of the Chief Executive Officer and preparing and submitting a report for inclusion in annual continuous disclosure documents as required. The People & Governance Committee is responsible for recommending to the Board new director nominees and for assessing current directors on an ongoing basis. The People & Governance Committee is also responsible for reviewing Corporation's response to and implementation of the guidelines set forth from time to time by any applicable regulatory authorities.

*Technical Committee*

The Technical Committee is responsible for overseeing all of the technical aspects of the Corporation's mineral properties, including material exploration, development, permitting, and mining operations.

*ESG Committee*

The ESG Committee advises and supports the Chief Executive Officer in determining and implementing the Corporation's wide range environmental and social sustainability initiatives, based on the selected sustainable development goals for each of the two aspects of ESG: "E" environmental and "S" social. The key initiatives of the ESG Committee are: (i) establishing the Investment Agency which encompasses the coordination of the social programs of the Corporation; and (ii) overseeing strategy and coordinating with the Technical Committee to drive the Corporation to its ambitious net zero 2024 targets (measured as emissions minus carbon credits), within this Decade of Action and 26 years ahead of United Nations' 2050 targets.

![](sgml202606026k_002.jpg)

**Term Limits**

The Corporation has not instituted director term limits. The Corporation believes that in taking into account the nature and size of the Board and the Corporation, it is more important to have relevant experience than to impose set time limits on a director's tenure, which may create vacancies at a time when a suitable candidate cannot be identified and as such would not be in the best interests of the Corporation. In lieu of imposing term limits, the Corporation regularly monitors director performance through annual evaluations and regularly encourages sharing and new perspectives through regularly scheduled Board meetings, meetings with only independent directors in attendance, as well as through continuing education initiatives. On a regular basis, the Corporation analyzes the skills and experience necessary for the Board and evaluates the need for director changes to ensure that the Corporation has highly knowledgeable and motivated Board members, while ensuring that new perspectives are available to the Board.

**Designated Group Representation in Management and on the Board**

The Corporation extends opportunities to all internal personnel and outside candidates, without distinction as to gender, race, colour, religion, sexual orientation, family or marital status, political belief, age, national or ethnic origin, citizenship, disability, or any other basis and strives for diversity of experience, perspective and education. The Corporation encourages representation of "designated groups" (being women, Indigenous peoples (First Nations, Inuit and Métis), persons with disabilities, and members of visible minorities) on the Board and in executive officer positions. Although the Corporation currently does not yet have a written policy relating to designated group representation, the Corporation has considered the level of designated group representation in its executive officer positions and on the Board in previous nominations.

For the period ended on June 30, 2026, the Corporation had five Board members, two of whom are women (40% in percentage terms), and two executive officers, one of whom is a woman (50% in percentage terms), being the Co-Chair and Chief Executive Officer of the Corporation. The directors nominees are a total of five, two of whom are women (40% in percentage terms).

The Corporation's focus has always been, and will continue to be, working to attract the highest quality executive officers and Board candidates with special focus on the skills, experience, character and behavioural qualities of each candidate.

**AUDIT, FINANCE AND RISK COMMITTEE**

The purpose of the Corporation's Audit, Finance and Risk Committee is to provide assistance to the Board in fulfilling its legal fiduciary obligations with respect to matters involving the accounting, auditing, financial reporting, internal control and legal compliance functions of the Corporation. It is the objective of the Audit, Finance and Risk Committee to maintain free and open means of communications among the Board, the independent auditors and the financial and senior management of the Corporation.

Pursuant to NI 52-110, the Corporation is required to disclose certain information with respect to its Audit, Finance and Risk Committee. Such information can be found under the heading "*Audit, Finance and Risk Committee Information*" in the most recent annual information form of the Corporation dated March 30, 2026, as filed by the Corporation on SEDAR+ at www.sedarplus.ca.

**ADDITIONAL INFORMATION**

Financial information of the Corporation is provided in the Corporation's financial statements, management's discussion and analysis, and annual information form for its most recently completed financial year. A copy of these documents may be obtained by contacting the Corporation's Chief Financial Officer at 181 Bay Street, Suite 4400, Toronto, Ontario, M5J 2T3.

&nbsp;&nbsp;**SCHEDULE "A" <br> Board Mandate**

This Board of Directors Mandate (this "Mandate") has been adopted by the Board (as defined below) as of September, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **GENERAL** 

The Board of Directors (the "Board") of Sigma Lithium Corporation (together with its subsidiaries, as applicable, the "Corporation") is responsible for the stewardship of the Corporation's affairs and the activities of management of the Corporation in the conduct of day to day business, all for the benefit of its shareholders.

The primary responsibilities of the Board are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) to maximize long term shareholder
value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) to approve the strategic plan
of the Corporation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) to ensure that processes, controls
and systems are in place for the management of the business and affairs of the Corporation and to address applicable legal and regulatory
compliance matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) to maintain the composition of
the Board in a way that provides an effective mix of skills and experience to provide for the overall stewardship of the Corporation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) to ensure that the Corporation
meets its obligations on an ongoing basis and operates in a safe and reliable manner; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) to monitor the performance of
the management of the Corporation to ensure that it meets its duties and responsibilities to the shareholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **COMPOSITION AND OPERATION** 

The number of directors shall be not less than the minimum and not more than the maximum number specified in the Corporation's articles and shall be set from time to time within such limits by resolutions of the shareholders or of the Board as may be permitted by law. Directors are elected to hold office for a term of one year. The composition of the Board must also meet any applicable Canadian residency requirements. The Board will analyze the application of the "independent" standard, as such term is defined in National Instrument 52-110 – *Audit Committees*, to individual members of the Board on an annual basis and disclose that analysis. The Board will in each year appoint a chairperson of the Board (the "**Chair**").

The Board operates by delegating certain of its authorities to management and by reserving certain powers to itself. The Board retains the responsibility of managing its own affairs including (i) selecting its Chair, (ii) nominating candidates for election to the Board, (iii) constituting committees of the Board and (iv) determining compensation for the directors. Subject to the articles and by-laws of the Corporation and the *Canada Business Corporations Act* (the "CBCA"), the Board may constitute, seek the advice of, and delegate certain powers, duties and responsibilities to, committees of the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **MEETINGS** 

The Board shall have a minimum of four regularly scheduled meetings per year. Special meetings are called as necessary. Occasional Board trips are scheduled, if possible, in conjunction with regular Board meetings, to offer directors the opportunity to visit sites and facilities at different operational locations. A quorum for a meeting of the Board shall consist of a simple majority of the members of the Board.

The Board will schedule regular sessions (at a minimum, during or immediately following each regularly scheduled Board meeting) for independent directors to meet without non-independent directors or members of management in attendance.
