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.

How May the Annual General Meeting Materials Be Accessed?

We have elected to provide access to our Proxy Materials over the internet. Accordingly, we are mailing a notice (the "Information Notice") on April 26, 2024, regarding internet availability of Proxy Materials to our street name holders (beneficial shareholders) of record as of close of business (EDT) on April 24, 2024 (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, 2023 and our Annual Report on Form 20-F on the websites referred to in the Information Notice (https://ri.nexaresources.com/corporate-governance/shareholders-meeting/ and https://ri.nexaresources.com/financial-information/annual-reports/) 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.sedarplus.ca. 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.

We are mailing the Proxy Materials on April 26, 2024, 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 Meeting and to vote at the Meeting. 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.

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.

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, 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, 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 Meeting in-person and vote at the Meeting (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. 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 by:

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.

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, Board 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 committees and executive Board meetings (management committee); 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 that include internal rules for the Board of Directors and 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, in line with ESG standards. The disclosure set out below describes in further detail our approach to corporate governance.

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 or permitted. 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. Furthermore, according to the Board of Directors' internal rules, the Directors may participate in a meeting of the Board by means of telephone conference or similar communication means, allowing the identification of each participating Director and by means of which all persons participating in the meeting can hear and speak to each other on a continuous basis. Participation in a meeting via telecommunication means will constitute presence in person at the meeting, provided that all actions approved by the Directors at any such meeting will be reproduced in writing in the form of resolutions. In fiscal year 2023, our Board of Directors held eight meetings, in which the rate of attendance in person or by representation was 100% of the directors. In addition, we had (i) nine audit committee meetings, (ii) five finance committee meetings, (iii) six compensation, nominating and governance committee meetings, and (iv) eight sustainability and capital projects committee meetings.

As set forth in the Board of Directors' internal rules, the independent Directors may hold meetings in which members of the management team and the non-independent Directors are not present. In 2023, our Directors held in camera sessions without members of the management team prior and/or at the conclusion of each Board meeting.

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.

The charter for each of the committees of our Board of Directors is available on our website.

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.

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 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 Dimitrov, Hilmar Rode and Jaime Ardila 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 relationships with local communities, tailings management, water, waste, biodiversity, and GHG emissions (climate change), as well as with respect to the estimation and disclosure of mineral resources and reserves at all operations and projects (collectively "Sustainability Matters"). The committee also assists the Board of Directors with the oversight of our ESG strategy, including its revision and implementation, in connection with Sustainability Matters and all related applicable laws.

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 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 two-year terms 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, by a simple majority vote of the directors present or represented, fill the vacancy. In these circumstances, the following general meeting of shareholders shall make the final appointment of the director.

Mandate for the Board of Directors

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

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:

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. As part of the education session, certain directors obtained international certifications related to the competencies necessary for their activities, such as National Association of Corporate Directors ("NACD") Directorship Certification.

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.

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's 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 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 and management team, each of the Board's committees and each director, the Board 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 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 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, 17.5% of our overall employees are women.

Further, we developed a diversity 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.

The program promotes knowledge, improvements and awareness of diversity in the workplace for our employees. In 2023, we held the Plurality Week, a week dedicated to discussions on the 5 affinity groups, including lectures with external guests. We also continued participating in the Companies and Rights Forum LGBTI+ and continued our partnership with Women in Mining ("WIM") in Brazil and Peru. In 2023, we signed a letter of commitment to expand and strength the representation of women in the mining industry, fostering a dynamic business environment that not only attracts and retains woman employes, but also harnesses their unique strengths and recognizes their significant contributions. Nexa's Empodera (Empower) group remained active in community events, promoting discussions about motherhood, harassment, female empowerment and women in the local communities in which our projects are located. We also continued working with our affinity group for people with disabilities and carried out an accessibility survey in all units and offices to evaluate how our structures are serving the disabled. We also launched a podcast to discuss the inclusion of people with disabilities and publicized the digital tools we have implemented into our workplaces. In Brazil, 4.2% of our employees identify as people with disabilities, and by 2030 our diversity target is to have a workforce composed 30% of women employees and 30% of women in leadership positions. These targets are frequently monitored, both globally and locally, and action plans are currently being implemented to achieve the proposed targets.

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.

Code of conduct

We work with all of our employees, as well as third parties who we work with, 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. The Code of Conduct reflects our commitment to the principles of anti-corruption, anti-money laundering, anti-terrorist financing, integrity, ethics, human rights, social and environmental responsibilities and antitrust policies based on laws in effect in the countries where we operate. 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. The last update of our Code of Conduct occurred in 2021 since then we continued with its dissemination to current and new employees at a global level and in 2024, we expect to review our Code of Conduct and consequently issue a new version. In 2022, we also launched our Code of Conduct for Suppliers started to disseminate it to any suppliers considered to be strategic vendors. A conduct committee is in charge of promoting the implementation of the code and supervising the application of disciplinary measures. In 2023, we launched the Code of Conduct for Customers and started disseminating it as well.

Anti-corruption, anti-money laundering and antitrust programs have been implemented, 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, code of conduct for suppliers and 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 have been, and expect to continue, taking 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.

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 these considerations. The following table briefly describes the significant differences between our practices and the practices of U.S. domestic issuers under NYSE corporate governance rules.
