PROXY STATEMENT
ANNUAL GENERAL MEETING OF SHAREHOLDERS AND EXTRAORDINARY GENERAL MEETING OF SHAREHOLDERS
JUNE 10, 2021

GENERAL INFORMATION

This Proxy Statement is being provided to solicit proxies on behalf of the Board of Directors of Nexa Resources S.A. (the 'Company', 'Nexa', 'we', 'our' or 'us') for use at the 2021 Annual General Meeting of Shareholders (the 'Annual General Meeting') to be held on June 10, 2021, at 3 p.m. Luxembourg time and the Extraordinary Meeting of Shareholders to be held immediately following the Annual General Meeting (the 'Extraordinary General Meeting' and together with the Annual General Meeting, the 'Meetings') at the Company's registered office located at 37A, Avenue J. F. Kennedy, L-1855 Luxembourg, Grand Duchy of Luxembourg and any adjournment or postponement thereof. This Proxy Statement is available on our website at https://ir.nexaresources.com/shareholdersmeeting and our Annual Report on Form 20-F for the year ended December 31, 2020 (the 'Annual Report on Form 20-F') is available on our website at https://ir.nexaresources.com/regulatoryfilings and all of the aforementioned documents are available under the Company's profile on EDGAR at www.sec.gov and SEDAR at www.sedar.com. Copies of the Company's consolidated financial statements and annual accounts for the financial year ended December 31, 2020 and the proposed amendments to the Company's Articles are available on our website at https://ir.nexaresources.com/shareholdersmeeting. The Proxy Statement will also be made available to our 'street name' holders (meaning beneficial owners with their shares held through a bank, brokerage firm or other record owner) and registered shareholders as of the Record Date (as defined below) through the delivery methods described below.

This Proxy Statement, together with the Convening Notice containing the agenda and the proxy card with reply envelope, are hereinafter referred to as the 'Proxy Materials.'

Status as a Foreign Private Issuer and SEC foreign Issuer

We are a 'foreign private issuer' within the meaning of Rule 405 of the U.S. Securities Act of 1933, as amended, and Rule 3b-4 of the U.S. Securities Exchange Act of 1934, as amended (the 'Exchange Act'), and as a result, we are exempt from the U.S. Securities and Exchange Commission's proxy rules under Rule 3a12-3(b) of the Exchange Act.

In accordance with applicable Canadian securities laws, as an 'SEC foreign issuer' (as such term is defined in National Instrument 71-102 - Continuous Disclosure and Other Exemptions Relating to Foreign Issuers), we are exempt from certain requirements under Canadian securities laws relating to continuous disclosure obligations, proxy solicitation and certain other matters provided that we comply with appropriate requirements in the United States and our jurisdiction of incorporation, if applicable. However, recognizing that good corporate governance plays an important role in our overall success and in enhancing shareholder value, we have determined to voluntarily comply with certain best practice guidelines and to provide certain disclosures. These are discussed in further detail under the heading 'Corporate Governance' below in this Proxy Statement.

1

How May the Annual General Meeting and Extraordinary General Meeting Materials Be Accessed?

(a) Street name holders (beneficial shareholders)

We have elected to provide access to our Proxy Materials over the internet. Accordingly, we are mailing a notice (the 'Information Notice') on April 30, 2021 regarding internet availability of Proxy Materials to our street name holders (beneficial shareholders) of record as of close of business (EDT) on April 28, 2021 (the 'Record Date'). You will have the ability to access the Proxy Materials, the Company's consolidated financial statements and its annual accounts for the financial year ended December 31, 2020, the proposed amendments to the Company's Articles and our Annual Report on Form 20-F on the websites referred to in the Information Notice (https://ir.nexaresources.com/shareholdersmeeting and https://ir.nexaresources.com/regulatoryfilings) or street name holders (beneficial shareholders) may request to receive a printed set of the Proxy Materials. The Information Notice, this Proxy Statement and Annual Report on Form 20-F are, or will be, available under the Company's profile on EDGAR at www.sec.gov and SEDAR at www.sedar.com. Instructions on how to access the Proxy Materials either by viewing them online or by requesting a copy may be found in the Information Notice. You will not receive a printed copy of the Proxy Materials unless you have requested one when setting up your brokerage account or request one in the manner set forth in the Information Notice. This permits us to conserve resources and reduces our printing costs, while giving shareholders a convenient and efficient way to access our Proxy Materials.

(b) Registered shareholders

We are mailing the Proxy Materials on April 30, 2021 to all registered shareholders of our common shares as of the Record Date.

Who May Vote?

Only registered shareholders or street name holders (beneficial shareholders) of our common shares as of the Record Date will be entitled to notice of the Meetings and to vote at each of the Meetings. As of the Record Date, 132,438,611 common shares were issued and outstanding, out of which 132,438,611 common shares are entitled to one vote per common share at each Meeting.

What Constitutes an Attendance Quorum?

No quorum is required for any ordinary resolutions to be considered at the Annual General Meeting. For any extraordinary resolutions to be considered at the Extraordinary General Meeting, at least one-half of our issued share capital as of the date of such meeting will constitute a quorum. If such quorum is not present, the Extraordinary General Meeting may be adjourned and convened at a later date in which no quorum is required, provided that certain notice procedures are fulfilled. Abstentions are not considered 'votes' but the common shares with respect to which such abstentions are expressed do count as shares present for purposes of determining a quorum.

What Are Broker Non-Votes and Abstentions?

Broker non-votes occur when brokers holding shares in street name for beneficial owners do not receive instructions from the beneficial owners about how to vote their shares and the broker is unable to vote the shares in its discretion in the absence of an instruction. An abstention occurs when a shareholder withholds such shareholder's vote on a particular matter by checking the 'ABSTAIN' box on the proxy card.

2

Your broker will NOT be able to vote your shares with respect to any of the proposals or other matters considered at the Annual General Meeting or Extraordinary General Meeting, unless you have provided instructions to your broker. We strongly encourage you to provide instructions to your broker to vote your shares and exercise your right as a shareholder. A vote will not be cast in cases where a broker has not received an instruction from the beneficial owner.

With respect to all of the proposals or other matters considered at the Annual General Meeting or Extraordinary General Meeting, only those votes cast 'FOR' or 'AGAINST' are counted for the purposes of determining the number of votes cast with respect to each such proposal.

Broker non-votes and abstentions are not considered votes cast and have no effect on the outcome of any of the proposals.

What Is the Process for Voting?

If you are a registered shareholder, you can vote by mail by marking, dating, signing and returning the proxy card in the postage-paid envelope. Submitting your proxy by mail will not affect your ability to attend the Meetings in-person and vote at the Meetings (subject to compliance with the procedures set forth in this Proxy Statement and the requirements under applicable law).

If your shares are held in 'street name' and you are a beneficial shareholder, you will receive instructions from your bank, brokerage firm or other record owner. You must follow the instructions of the bank, brokerage firm or other record owner in order for your common shares to be voted.

The Company will retain an independent tabulator to receive and tabulate the proxies.

If you submit a proxy and direct how your shares will be voted, the individuals named as proxies will vote your shares in the manner you indicate. If you submit a proxy but do not direct how your shares will be voted, the individuals named as proxies will vote your shares 'FOR' the election of each of the nominees for director and 'FOR' each of the other proposals identified herein.

It is not expected that any other matters will be brought before the Annual General Meeting or the Extraordinary General Meeting. If, however, other matters are properly presented, the individuals named as proxies will vote in accordance with their discretion with respect to such matters.

What Is the Process for Revocation of Proxies?

A registered shareholder who has given a proxy may revoke it at any time before it is exercised at the Annual General Meeting or the Extraordinary General Meeting by:

· attending the Annual General Meeting and/or the Extraordinary General Meeting and voting in person;
· delivering a written notice dated on or before June 4th, 2021, at 6:00 p.m. Luxembourg time, 12:00 p.m. EDT at the address given below, stating that the proxy is revoked; or
· signing and delivering a subsequently dated proxy card prior to the vote at the Annual General Meeting and the Extraordinary General Meeting.

If you are a registered shareholder, you may request a new proxy card by contacting our Investor Relation department by email at ir@nexaresources.com.

3

Registered shareholders should send any written notice or new proxy card by (i) regular mail to Nexa Resources S.A., c/o Computershare, PO Box 505000, Louisville, KY 40233-5000, or (ii) by courier or U.S. overnight mail to Nexa Resources S.A., c/o Computershare, 462 South 4th Street, Suite 1600, Louisville, KY 40233-5000 (Telephone: +1 800-368-5948).

Any street name holder (beneficial shareholder) may change or revoke previously given voting instructions by contacting the bank or brokerage firm holding the shares or by obtaining a legal proxy from such bank or brokerage firm and voting in person at the Annual General Meeting or the Extraordinary General Meeting, by delivering a written notice dated on or before June 4th, 2021, at 6:00 p.m. Luxembourg time, 12:00 p.m. EDT, stating that the voting instructions are revoked or changed. Your last voting instructions, prior to or at the Annual General Meeting or the Extraordinary General Meeting, are the voting instructions that will be taken into account.

Who May Attend the Annual General Meeting and the Extraordinary General Meeting?

Only holders of our common shares as of the Record Date or their legal proxy holders may attend the Meetings. All holders of our common shares planning to attend the Annual General Meeting and the Extraordinary General Meeting in person must contact our Investor Relation department, at ir@nexaresources.com by 6:00 p.m. Luxembourg time, 12:00 p.m. EDT, on June 4th, 2021 to reserve a seat.

We recommend you to consult the travel guidelines from your national authority as well as our website with respect to any additional steps we may decide to take with respect to the conduct of the Meetings in the context of the COVID-19 outbreak.

· Registered shareholders

To be admitted to the Annual General Meeting and the Extraordinary General Meeting, you will need a form of photo identification. You will be admitted to the Meetings only if we are able to verify your common shareholder status by checking your name against the list of registered common shareholders as of the Record Date.

· Beneficial shareholders

To be admitted to the Meetings, you will need a form of photo identification. A beneficial shareholder must also bring valid proof of ownership of your common shares as of the Record Date; in order to vote at the Meetings you must bring a valid legal proxy from the holder of record.

If you hold your common shares as a beneficial holder in street name through a bank or brokerage firm, a brokerage statement reflecting your ownership as of the Record Date or a letter from a bank or broker confirming your ownership as of the Record Date is sufficient proof of ownership to be admitted to the Meetings.

Registration will begin at 2:30 p.m. Luxembourg time and the Annual General Meeting will begin at 3 p.m. Luxembourg time. The Extraordinary General Meeting will immediately follow the adjournment of the Annual General Meeting.

No cameras, recording equipment, electronic devices (including cell phones) or large bags, briefcases or packages will be permitted in the Meetings.

Representatives of PricewaterhouseCoopers, société coopérative, the Company's statutory auditor (réviseurs d'entreprises agréés), will attend the Annual General Meeting.

We intend to hold the Annual General Meeting and the Extraordinary General Meeting in person in the Grand Duchy of Luxembourg. However, we are actively monitoring the public health and travel safety concerns relating to the coronavirus (COVID-19) outbreak and the advisories or mandates that the European Union and national and local governments may issue. In the event that we determine that it is necessary or appropriate to take additional steps regarding how we conduct these meetings, we will announce this decision in advance, and details will be posted on our website. Please check our website prior to the Annual General Meeting and the Extraordinary General Meeting if you are planning to attend in person.

What Is the Process for the Solicitation of Proxies?

We will pay the cost of soliciting proxies for the Meetings. We may solicit by mail, telephone, personal contact and electronic means and arrangements are made with brokerage houses and other custodians, nominees and fiduciaries to send the Information Notice, and if requested, Proxy Materials, to beneficial owners. Upon request, we will reimburse them for their reasonable expenses. In addition, our directors, officers and employees may solicit proxies, either in-person or by telephone, facsimile or written or electronic mail (without additional compensation).

PROPOSAL WITH RESPECT TO AGENDA ITEM NO. 1 TO THE EXTRAORDINARY
GENERAL MEETING
AMENDMENT OF THE ARTICLES OF ASSOCIATION OF THE COMPANY

The Board of Directors is seeking approval by the shareholders to amend article 10 of the Articles of the Company by deleting the threshold mentioned in article 10.4.1 related to internal aspects of the Management Committee, in order to avoid duplication of rules with the authorization policy of the Company.

10.2 The Managing Officers are appointed by the Board of Directors of the Company for a period not exceeding one (1) year (renewable) which may at any time and 'ad nutum' remove and replace them. Their remuneration is determined by the Board of Directors.

10.3        The Board of Directors shall approve the internal regulations of the Management Committee, which shall set forth its duties and any other management powers and attributions including, but not limited to: the powers to perform acts or transactions involving the Company, the authorization limits of the Management Committee, appointment and removal of the Daily Managers (as defined below), and any other specific power that may be attributed to the Management Committee by the Board of Directors as determined in the relevant resolution of the Board of Directors to that effect or in the internal regulations of the Management Committee.'

Approval of this proposal requires the affirmative vote of a two-thirds majority of the votes validly cast on such resolution, where the shares represented at the meeting represent at least half of the issued share capital.

Our Board of Directors unanimously recommends a vote 'FOR' the approval of the
amendments to article 10 of the Articles of the Company.

CORPORATE GOVERNANCE

Our corporate governance model is aimed at facilitating the flow of information between our executives and other key decision-makers on our management team, specifically, our Board of Directors, advisory committees and management committee. Our corporate governance model also provides a framework for the duties of our management team, including oversight of Nexa's performance and decision-making. Our main corporate governance activities include support for Board of Directors, board advisory committees and executive board meetings; contribution to the process of preparing the annual report on governance practices; and elaboration of governance documents and updating of best practices.

Our corporate governance model is designed to ensure that the proper corporate governance principles are consistently applied within our organization. We have adopted certain corporate governance policies and practices in line with the Corporate Governance Guidelines ('Canadian Corporate Governance Guidelines') issued by the Canadian Securities Administrators pursuant to National Policy 58-201, together with certain related disclosure requirements pursuant to National Instrument 58-101- Disclosure of Corporate Governance Practices. These include adopting board internal rules for the Board of Directors and appointing key committees that have independent representation and leadership, including an audit committee and a compensation, nominating and governance committee. The charter for the compensation, nominating and governance committee includes responsibility for reviewing and assessing the size, composition and operation of the Board of Directors to ensure effective and independent decision making, advising on potential conflicts of interest situations and developing corporate governance guidelines and principles. The disclosure set out below describes in further detail our approach to corporate governance in relation to the Canadian Corporate Governance Guidelines.

Meetings of the Board of Directors and attendance

The Board of Directors ordinarily meets in person or by other means of communication as may be required. The frequency of and agenda items for Board of Directors meetings will vary depending on the state of affairs, requirements for approvals and opportunities available to Nexa and the risks and issues which Nexa faces. The agenda for meetings places priority and focuses on key issues for Nexa, which are identified by the Chair of our Board of Directors (the 'Chair'). Routine business is dealt with after substantive discussions on the key issues.

Under the Board of Directors' internal rules and our Articles, the Boards of Directors can validly consider any matters and make decisions provided at least a majority of the members are in attendance in person or by representation. The Board of Directors' internal rules further provide that each member is entitled to one vote either in person or where duly represented as required by the Board of Directors internal rules. In fiscal year 2020, our Board of Directors held eleven meetings, in which the rate of attendance in person or by representation was 100% of the directors.

Committees of our Board of Directors

Our Board of Directors has an audit committee, a finance committee, a compensation, nominating and governance committee and a sustainability and capital projects committee. Our Board of Directors may have other committees as it may determine from time to time. Each of the standing committees of our Board of Directors has the composition and responsibilities assigned to them by the meeting of the Board of Directors that created such committee and as set forth in their respective committee charters. These charters set out, among other things, the roles and responsibilities of the chair of each committee. As set forth in the respective charters of the committees, each of the committees may meet with or without management of Nexa, as the case may be, at the discretion of the committee. The charter for each of the committees of our Board of Directors is available on our website.

14

Audit committee

Our audit committee is a standing committee established by our Board of Directors on March 28, 2017 to assist the Board of Directors in fulfilling certain of its oversight responsibilities. The audit committee may be composed of three to five members, each appointed by our Board of Directors for a term of one year. Daniella Elena Dimitrov, Edward Ruiz and Jane Sadowsky currently serve as its members. These individuals are independent under Canadian securities regulators' National Instrument 52-110 Audit Committees, as well as under Rule 10A-3 and applicable NYSE standards. In addition, each of them satisfies the financial literacy requirement under applicable rules. Our Board of Directors has determined that Mr. Edward Ruiz qualifies as an 'audit committee financial expert.'

Our audit committee's primary responsibilities are to assist the Board of Directors' oversight of: (i) quality and integrity of our financial reporting and related financial disclosure; (ii) the effectiveness of our internal control over financial reporting and disclosure controls and procedures; (iii) our compliance with legal and statutory requirements as they relate to financial statements and related financial disclosures; (iv) the monitoring of risk management controls and processes, according to the Enterprise Risk Management ('ERM') policy; (v) the compliance and ethics program; and (vi) the qualifications, performance and independence of our independent auditors and performance of the internal audit function.

Nexa has established policies and procedures that require any engagement of our independent auditor for audit or non-audit services to be submitted to and pre-approved by the audit committee. In addition, our audit committee may delegate the authority to pre-approve non-audit services to one or more of its members. All non-audit services that are pre-approved pursuant to such delegated authority must be presented to the full audit committee at its first scheduled meeting following such pre-approval. Our audit committee shall pre-approve all audit and non-audit services to be provided to us by our independent auditor and also has the authority to recommend pre-approval policies and procedures to our Board of Directors and for the engagement of our independent auditor's services.

Finance committee

Our finance committee is a standing committee established by our Board of Directors on March 28, 2017 to assist the Board of Directors in fulfilling certain of its oversight responsibilities. The finance committee may be composed of three to five members, each appointed by our Board of Directors for a term of one year. Gianfranco Castagnola, Edward Ruiz and João Henrique Batista de Souza Schmidt currently serve as its members.

Our finance committee's primary responsibilities are to assist the Board of Directors in fulfilling its oversight responsibilities with respect to monitoring Nexa's balance sheet and by providing recommendations on our capital management strategy and capital structure, including indebtedness, investments and returns, among others.

Compensation, nominating and governance committee

Our compensation, nominating and governance committee is a standing committee established by our Board of Directors on March 28, 2017 to assist the Board of Directors in fulfilling certain of its oversight responsibilities. The compensation, nominating and governance committee may be composed of two to five members, each appointed by our Board of Directors for a term of one year. Luís Ermírio de Moraes, Eduardo Borges de Andrade Filho, Jaime Ardila and Jane Sadowsky currently serve as its members. Two of the four members of the compensation, nominating and governance committee are independent directors. An external advisor with broad experience in the area was retained from January to June 2020 to assist our compensation, nominating and governance committee in carrying out its mandate.

15

Our compensation, nominating and governance committee is responsible for: (1) new compensation models and changes to compensation models currently used by us, in order to guide and influence our actions; (2) the compensation of the executive officers, of the members of the Board of Directors and of the members of the committees of the Board of Directors; (3) the proposal of candidates to the Chair or chief executive officer of the Company (the 'Chief Executive Officer' or 'CEO'), when applicable, or any serious restrictions on the candidates of the executive officers proposed by the Chief Executive Officer to the other chairs; (4) development of corporate governance guidelines and principles; (5) the identification of individuals qualified to be nominated as members of the Board of Directors and suggesting nominees to fill any vacancies on the Board of Directors; (6) the structure and composition of the Board of Directors committees; (7) evaluation of the performance and effectiveness of the Board of Directors, the Chief Executive Officer and each of the Board of Directors standing committees; (8) the supervision and approval of our social responsibility plans and policies; and (9) any related matters required by applicable laws and stock exchange rules.

Sustainability and capital projects committee

Our sustainability and capital projects committee is a standing committee established by our Board of Directors on April 29, 2019 to assist the Board of Directors in fulfilling certain of its oversight responsibilities. The capital projects oversight was added on December 3, 2020. The sustainability and capital projects committee may be composed of at least three and no more than five members, each appointed by our Board of Directors for a term of one year. Diego Hernandez, Daniella Elena Dimitrov and Ian Wilton Pearce currently serve as its members.

Our sustainability and capital projects committee's primary responsibilities are to assist the Board of Directors by supporting safe and sustainable business practices in the conduct of our activities in respect of environmental, health, safety and social matters, including tailings management. The committee also assists in the oversight of the estimate and disclosure of mineral reserves and resources related to our operations and projects.

The sustainability and capital projects committee is also responsible for assisting the Board of Directors with the review of technical, economic and social matters with respect to our projects, including exploration, development, permitting, construction and operation of our mining and smelting assets, which are core to our strategy and growth.

Appointment and term limits of members of our Board of Directors

In accordance with our Articles and the 1915 Law, the members of our Board of Directors are elected by a resolution of a general meeting of shareholders adopted with a simple majority of the votes validly cast, regardless of the portion of capital represented at such general meeting. Votes are cast for or against each nominee proposed for election to the Board of Directors and cast votes shall not include votes attaching to shares for which the shareholder has not participated in the vote, has abstained or has returned a blank or invalid vote.

Our directors are appointed for a one-year term and may be reelected. Members of our Board of Directors may be removed at any time, with or without cause, by a resolution adopted at a general meeting of our shareholders. Under Luxembourg law, in the case of a vacancy of the office of a director appointed by the general meeting of shareholders, the remaining directors may, unless the Articles provide differently, fill the vacancy on a provisional basis. In these circumstances, the following general meeting of shareholders shall make the final appointment of the director.

16

Mandate for the Board of Directors

Our Board of Directors adopted Board of Directors internal rules, which includes the following, among other things:

· approve the general guidance of our business, its mission, strategic goals and guidelines;
· ensure that the executive officers comply with such mission, strategic goals and guidelines;
· approve the budget and a strategic plan which takes into account, among other things, the opportunities and risks of the business;

· all further tasks as required by applicable law and our Articles.
17

The Board of Directors internal rules are available on our website.

The Board of Directors has at its disposal a set of provisions and practices that promotes independence in the decision-making process of the Board of Directors. In accordance with the Board of Director's internal rules, the independent members of the Board of Directors may hold separate meetings and each director has a duty to declare, prior to any Board of Directors meeting, the existence of a particular reason or conflict of interest with Nexa with respect to a subject matter being discussed or considered by the Board of Directors. Accordingly, such Board of Directors member would be refrained from discussing and voting on a matter that could present a conflict of interest. Additionally, our Board of Directors members are prohibited from holding executive positions with Nexa and/or serving on more than four boards of directors of companies that do not belong to the same conglomerate. As discussed above, our audit committee is comprised entirely of independent directors and we also have independent representation on all other committees.

Chair

The Chair of our Board of Directors is not an independent director of the Company. The Board of Directors has carefully considered governance issues relating to Chair independence and believes that the Chair carries out separate responsibilities diligently and that, with the compensating practices in place, the Board of Directors operates effectively and in Nexa's best interest.

Description of the position of Chair

Our Board of Directors has developed a written position description for the Chair of the Board of Directors. The Chair of the Board of Directors has the following responsibilities, subject to any other matters that may be set forth in our Articles or provided for under applicable law:

· ensure the efficiency and proper performance of the Board of Directors;
· preside over the Board of Directors meetings;
· prepare, organize, elaborate and distribute the agenda and minutes of the meetings aided by the Board of Directors secretary, including all information necessary to discuss the matters on the agenda;
· coordinate the activities of other Board of Directors members;
· ensure that all Board of Directors members receive comprehensive information about the items on the Board of Directors agenda in a timely manner;
· propose the annual corporate calendar to the Board of Directors in coordination with Nexa's CEO, which shall necessarily set forth the dates of corporate events;
· organize the onboarding and education sessions for incoming members of the Board of Directors in coordination with Nexa's CEO; and
· periodically arrange for continuing education opportunities for all Board of Directors members, so that individuals may maintain or enhance their skills and abilities as members, and ensure that their knowledge and understanding of Nexa's business remains current.

The Chair of our Board of Directors is not an independent director of Nexa Resources. The Board of Directors has carefully considered governance issues relating to Chair independence and believes that the Chair carries out separate responsibilities diligently and that, with the compensating practices in place, the Board of Directors operates effectively and in Nexa's best interest.

18

Orientation and continuing education

We implemented an orientation program for new directors under which each new director meets with the Chair of our Board of Directors and our executives. New directors are provided with comprehensive orientation and education as to our business, operations and corporate governance (including the role and responsibilities of the Board of Directors and each committee).

The Chair of our Board of Directors is responsible for overseeing directors' continuing education and ensure that it is designed to maintain or enhance the skills and abilities of our directors and to ensure that their knowledge and understanding of our business remains current. The chair of each committee is responsible for coordinating orientation and continuing director development programs relating to the committee's mandate.

Our ongoing director education programs entails site visits, presentations from outside experts and consultants, discussions on ongoing governance trends and guidelines for public companies, briefings from staff and management, and reports on issues relating to our projects and operations, sustainability and social matters, competitive factors, reserves, legal issues, economic, accounting and financial disclosure, mineral and hydrocarbon education and other initiatives intended to keep the Board of Directors abreast of new developments and challenges that we may face.

Evaluation of directors

Our compensation, nominating and governance committee established a framework for the implementation and administration of processes to assess the effectiveness of the Board of Directors and each of its members. This includes peer reviews of each director's performance and self-assessments, as well as full Board of Directors and committee review of the Board of Directors and the respective committees, by way of questionnaires, interviews and sessions with the Chair. In addition to hiring external advisors to develop and undertake this assessment, the compensation, nominating and governance committee is also responsible for overseeing the process and evaluating the results, with the objective of improving the performance of each director and the Board of Directors as a whole.

Considerations in evaluating director nominees

Our Board of Directors is responsible for nominating members for election to the Board of Directors and for filling vacancies on the Board of Directors that may occur between annual meetings of shareholders. The process for nominating a new director initiates with our compensation, nominating and governance committee which evaluates Nexa's current circumstances and establishes a profile for a director candidate. Such profile is then shared with a specialized external executive search firm, who assists the compensation, nominating and governance committee in selecting candidates for interviews. Prior to the interview, the specialized external firm is responsible for a background check with former employers and colleagues of the respective candidates.

Following the interview(s), our compensation, nominating and governance committee recommends the nomination of the director candidate to our Board of Directors based upon an assessment of the independence, skills, qualifications and experience of such candidate. Specifically, the Board of Directors seeks members from diverse professional and personal backgrounds who combine a broad spectrum of experience and expertise with a reputation for integrity.

19

Diversity

We value diversity of abilities, experience, perspective, education, gender, background, race and national origin. We believe that having a diverse Board of Directors can offer a breadth and depth of perspectives that enhance our performance. Recommendations concerning director nominees are based on merit and past performance as well as expected contribution to the Board of Directors performance and, accordingly, diversity is taken into consideration. We believe that having a diverse and inclusive organization overall is beneficial to our success, and we are committed to diversity and inclusion at all levels of our organization to ensure that we attract, retain and promote the brightest and most talented individuals. We have recruited and selected executives that represent a diversity of business understanding, personal attributes, abilities and experience.

The compensation, nominating and governance committee and our Board of Directors have the responsibility to review and assess the composition of the Board of Directors and each of its committees, and to identify, evaluate and recommend potential new directors. With respect to our executive officers, the compensation, nominating and governance committee reviews candidates recommended by the Chief Executive Officer and makes the final recommendation to the Board of Directors. In new director and executive officer appointments and ongoing evaluations of the effectives of our Board of Directors and management team, each of the Board of Directors committees and each director, the Board of Directors will take into consideration diversity as one of the factors in order to maintain an appropriate mix and balance of diversity, attributes, skills, experience and background on our Board of Directors and each of its committees and the management team. Ultimately, appointments to our Board of Directors and management team are based on merit against objective criteria and with due regard to the benefits of diversity in Board of Directors and management team composition and the desire to maximize the effectiveness of corporate decision making, having regard to our best interests and strategies and objectives, including the interests of our shareholders and other stakeholders. During our selection process for Board of Directors appointments, we seek to ensure that women candidates are always considered on the shortlist for nominations. Currently, two (or 20%) of our ten members of the Board of Directors are women, and on a general basis, 13% of our overall employees are women.

Further, we developed a plurality program in 2019 as part of the Nexa Way program. This program is composed of affinity groups, which are formed by employees on a volunteer basis and divided into five themes: (i) women, (ii) race and ethnicity, (iii) LGBTQIA+, (iv) people with disabilities and (v) multigenerational. The affinity groups are assisted by a technical committee composed of executive officers and employees in key areas such as human resources, compliance, legal and institutional relations. By 2025, our gender target is to have 20% of women represented companywide. This target is frequently monitored, global and locally, and action plans are currently being implemented to achieve the proposed goal.

Compensation-setting process

Our compensation, nominating and governance committee is responsible for assisting our Board of Directors in fulfilling its governance and supervisory responsibilities, and advising our Board of Directors with respect to evaluation and monitoring of compensation models and policies performed every two years, which takes into account peer companies and the challenges and opportunities we face. The committee's responsibilities also include administering and determining our compensation objectives and programs, reviewing and making recommendations to our Board of Directors concerning the level and type of the compensation payable, evaluating performance, implementing evaluation and improvement processes, and ensuring that policies and processes are consistent with our philosophy and the objectives of our compensation program.

20

Code of conduct

We work with all of our employees, as well as third parties who interact with them, to ensure they behave in a manner consistent with our values, code of conduct and the key principles of our compliance program, particularly as these relate to the environment, human rights and labor related issues, health and safety, and anti-bribery and corruption. In 2018, we updated our compliance program based on the anti-corruption, anti-money laundering, anti-terrorist financing and antitrust laws in effect in the countries where we operate. As a result of this, the code of conduct was revised and is supported by compliance-related policies and procedures that were disseminated and implemented throughout the Company. Our directors and executives have certified that they have read and that they will comply with our code of conduct. Furthermore, our Board of Directors periodically monitors compliance related topics. A conduct committee is in charge of promoting the implementation of the code and supervising the application of disciplinary measures.

We have introduced several anti-corruption, anti-money laundering and antitrust initiatives, including, among other things, ethics and compliance training and an ethics hotline which enables employees and third parties to report misconduct. Information reported through our ethics hotline is investigated and following the investigation, disciplinary action may be taken, if necessary. We have not granted any implicit or explicit waivers from any provision of our code of conduct since its adoption.

Our code of conduct and main compliance-related policies are publicly available on our website at https://www.nexaresources.com. We will disclose future amendments to, or waivers of, our code of conduct on the same page of our corporate website. Information contained on our website is not incorporated by reference into this Proxy Statement, and you should not consider it to be part of this Proxy Statement.

Foreign private issuer and controlled company exemptions

Because we are a foreign private issuer, the NYSE rules applicable to us are considerably different from those applied to U.S. companies. Accordingly, we intend to take advantage of certain exemptions from NYSE governance requirements provided in the NYSE rules for foreign private issuers. Subject to the items listed below, as a foreign private issuer we are permitted to follow home country practice in lieu of the NYSE's corporate governance standards. Luxembourg law does not require that a majority of our Board of Directors consist of independent directors or the implementation of a compensation committee or nominating and corporate governance committee. As a foreign private issuer, we must comply with four principal NYSE corporate governance rules: (i) we must satisfy the requirements of Exchange Act Rule 10A-3 relating to audit committees; (ii) our Chief Executive Officer must promptly notify the NYSE in writing after any executive officer becomes aware of any non-compliance with the applicable NYSE corporate governance rules; (iii) we must provide the NYSE with annual and interim written affirmations as required under the NYSE corporate governance rules; and (iv) we must provide a brief description of any significant differences between our corporate governance practices and those followed by U.S. companies under NYSE listing standards.

In addition, for purposes of the NYSE rules, as VSA beneficially owns a majority of our outstanding common shares, we are a 'controlled company.' 'Controlled companies' under those rules are companies of which more than 50.0% of the voting power is held by an individual, a group or another company. Accordingly, we are eligible to take advantage of certain exemptions from NYSE governance requirements provided in the NYSE rules. Specifically, as a controlled company under NYSE rules, we are not required to have a majority of independent directors or a compensation, nominating and corporate governance committee composed entirely of independent directors.

21

As described further above, we recognize that good corporate governance plays an important role in our overall success and in enhancing shareholder value and, accordingly, we have adopted certain corporate governance policies and practices that reflect our consideration of the recommended Canadian Corporate Governance Guidelines. The following table briefly describes the significant differences between our practices and the practices of U.S. domestic issuers under NYSE corporate governance rules.

Section

NYSE corporate governance rule for
U.S. domestic issuers

Our approach

303A.01 A listed company must have a majority of independent directors. 'Controlled companies' and 'foreign private issuers' are not required to comply with this requirement.

We are a controlled company because more than a majority of our voting power for the appointment of directors is controlled by VSA. We are a foreign private issuer because we are incorporated in Luxembourg. As a controlled company and foreign private issuer, we are not required to comply with the majority of independent director requirements.

Four of our ten directors are independent. Our Board of Directors has adopted internal rules equivalent to a charter. See 'Corporate Governance, management and employees-Board of Directors' for a description of our Board of Directors and processes our Board of Directors has implemented to promote the exercise of independent judgment.

303A.03 The non-management directors of a listed company must meet at regularly scheduled executive sessions without management. We have no management directors.
303A.04

A listed company must have a nominating/corporate governance committee composed entirely of independent directors, with a written charter that covers certain minimum specified duties.

'Controlled companies' and 'foreign private issuers' are not required to comply with this requirement.

As a controlled company and foreign private issuer, we are not required to comply with the nominating/corporate governance committee requirements. However, we do have a compensation, nominating and governance committee composed of two independent directors and two non-independent directors, which has adopted a committee charter.

As set for in the committee's charter, this committee is responsible for, among other matters:

·identifying individuals qualified to be nominated as members of the Board of Directors;

·suggesting names to fill any vacancies on the Board of Directors;

·developing corporate governance guidelines and principles; and

·evaluating the performance and effectiveness of the Board of Directors, the CEO and each of committees.

See 'Corporate Governance, management and employees-Board of Directors-Committees of our Board of Directors.'

22

Section

NYSE corporate governance rule for
U.S. domestic issuers

Our approach

303A.05

A listed company must have a compensation committee composed entirely of independent directors, with a written charter that covers certain minimum specified duties.

'Controlled companies' and 'foreign private issuers' are not required to comply with this requirement.

As a controlled company and foreign private issuer, we are not required to comply with the compensation committee requirements. However, we do have a compensation, nominating and governance committee composed of two independent directors and two non-independent directors, which has adopted a committee charter.

As set forth in the committee's charter, this committee is responsible for, among other matters:

·reviewing and proposing new compensation models and changes to current compensation models; and

·determining compensation of executive officers, directors and committee members.

See 'Corporate governance, management and employees-Board of Directors-Committees of our Board of Directors.'

303A.06

303A.07

A listed company must have an audit committee with a minimum of three independent directors who satisfy the independence requirements of Rule 10A-3 under the Exchange Act, with a written charter that covers certain minimum specified duties.

We have an audit committee composed of three members, all of whom qualify as independent under Rule 10A-3 and applicable NYSE standards. Each member of the audit committee also satisfies the financial literacy requirement under applicable standards. The audit committee has adopted a committee charter, which was duly approved by our Board of Directors.

As set forth in the committee's charter, the committee shall assist the Board of Directors in fulfilling its oversight responsibilities with respect to:

·quality and integrity of our financial reporting and related financial disclosures;

·the effectiveness of our internal control over financial reporting and disclosure controls and procedures;

·our compliance with legal and statutory requirements as they relate to financial statements and related financial disclosures;

·our risk management controls and monitoring processes, according to the ERM policy; and

·the qualifications, performance and independence of our independent auditors and performance of the internal audit function.

See 'Corporate governance, management and employees-Board of Directors-Committees of our Board of Directors.'

23

Section

NYSE corporate governance rule for
U.S. domestic issuers

Our approach

303A.08 Shareholders must be given the opportunity to vote on all equity-compensation plans and material revisions thereto, with limited exemptions set forth in the NYSE rules. Our articles of association require shareholder approval of overall remuneration, including any equity-compensation plans of members of the Board of Directors and members of Board of Directors committees.
303A.09 A listed company must adopt and disclose corporate governance guidelines that cover certain minimum specified subjects. We have corporate governance policies in place as described in 'Corporate governance, management and employees' in this Proxy Statement.
303A.10 A listed company must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waivers of the code for directors or executive officers. We have adopted a formal code of conduct, which applies to our directors, officers, employees and third parties who interact with the Company. Our code of conduct has a scope that is similar, but not identical, to that required for a U.S. domestic company under the NYSE rules.
303A.12

(a) Each listed company CEO must certify to the NYSE each year that he or she is not aware of any violation by the Company of NYSE corporate governance listing standards.

(b) Each listed company CEO must promptly notify the NYSE in writing after any executive officer of the listed company becomes aware of any non-compliance with any applicable provisions of this Section 303A.

(c) Each listed company must submit an executed Written Affirmation annually to the NYSE. In addition, each listed company must submit an interim Written Affirmation as and when required by the interim Written Affirmation form specified by the NYSE.

As a foreign private issuer, we are subject to and comply with (b) and (c) of these requirements but are not subject to (a).
24

MANAGEMENT

Board of Directors

Our Board of Directors is responsible for the general guidance of our business and affairs, including providing general guidance, governance and strategic oversight to our executives and other members of our management team. It is also responsible for ensuring that we meet our objectives, as well as for monitoring our performance and ensuring business continuity. The Board of Directors is vested with broad powers to act on behalf of Nexa and to perform or authorize all acts of administrative or ancillary nature necessary or useful to accomplish our corporate purpose. All powers not expressly reserved by law to the shareholders fall within the competence of our Board of Directors. Our Board of Directors is comprised of a minimum of five and a maximum of eleven members and currently has ten members, of which four are independent directors and six are non-independent, as set out below. The non-independent directors are non-independent on the account of such directors either also being executive officers of Nexa, its subsidiaries or its controlling shareholder, as applicable, or having been retained to provide consulting services to Nexa.

In 2020, one director, Gianfranco Castagnola, was elected to our Board of Directors for the first time. Our Articles provide that directors are appointed for terms not to exceed one year. The term of each and all of our directors expires at the 2021 annual general meeting of shareholders. The following table sets forth our current directors, their respective Board of Directors positions and their respective date of election to the Board of Directors.

If you own common shares beneficially through a bank, broker or otherwise, you will be admitted to the Meetings upon presenting a form of photo identification and proof of share ownership as of the Record Date; in order to vote at the Meetings, you must bring a valid proxy signed by the record holder. A recent brokerage statement reflecting your ownership as at the close of business (EDT) on April 28, 2021 (the 'Record Date') or a letter from a bank or broker confirming your ownership as at the Record Date are examples of proof of share ownership for purposes of admission to the Annual General Meeting and the Extraordinary General Meeting. If you are a holder of common shares you will be entitled to vote at the Annual General Meeting and the Extraordinary General Meeting or any adjournment or postponement thereof.

Regardless of whether or not you plan to attend the Annual General Meeting or the Extraordinary General Meeting, please follow the instructions you received to authorize a proxy to vote your shares as soon as possible to ensure that your shares are represented at the Annual General Meeting and the Extraordinary General Meeting. Any shareholder that decides to attend the Annual General Meeting or the Extraordinary General Meeting in person may, if so desired, revoke the prior proxy by voting such person's common shares at the Annual General Meeting as further described in the Proxy Statement under the heading 'What Is the Process for Revocation of Proxies?'.
