Important Notice Regarding the Availability of Proxy Materials for the Meeting

We are using "notice and access" to deliver to shareholders the Circular, Hudbay's audited consolidated financial statements for the years ended December 31, 2025 and 2024 and management's discussion and analysis related thereto and any other proxy-related materials (collectively, the "Proxy-Related Materials") by providing electronic access to such documents instead of mailing paper copies. Notice and access is an environmentally friendly and cost-effective way to distribute these materials since it reduces printing, paper and postage.

The Proxy-Related Materials are available on our website at www.hudbayminerals.com/disclosure-centre, on the website of our transfer agent, TSX Trust Company, at https://docs.tsxtrust.com/2219 and under our profile on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar.shtml. Please be sure to review the Circular before voting.

Should you wish to receive a paper copy of the Proxy-Related Materials or if you have any questions about notice and access, please contact our transfer agent, TSX Trust Company, by toll-free telephone at 1-866-600-5869 or by email at [email protected]. Paper copies of the Proxy-Related Materials will be made available free of charge. A paper copy will be sent to you within three business days of receiving your request if received in advance of the Meeting or within ten calendar days if a request is received on or after the date of the Meeting and within one year of the date the Proxy-Related Materials were filed on SEDAR+. If you wish to receive a paper copy of any of these documents before the May 14, 2026 proxy cutoff, please contact TSX Trust Company by May 7, 2026.

Important Notice Regarding the Virtual Meeting

Hudbay will be holding the Meeting as a completely virtual meeting, which will be conducted via live webcast, where all shareholders regardless of geographic location will have an opportunity to attend the Meeting.

Shareholders may vote their common shares online or by mail according to the directions on the form of proxy or voting instruction form, as applicable. Registered shareholders and duly appointed proxyholders will be able to attend, participate and vote at the Meeting online at https://meetings.lumiconnect.com/400-690-725-785. Non-registered shareholders (being shareholders who hold their Shares through a broker, investment dealer, bank, trust company, custodian, nominee or other intermediary) who have not duly appointed themselves as proxyholder will not be able to vote at the Meeting. However, such non-registered shareholders may still attend the Meeting as guests.

Shareholders who are unable to attend the Meeting are encouraged to complete, date, sign and return their form of proxy so that as large a representation as possible may be had at the Meeting.

Shareholders who wish to appoint a person other than the Hudbay representatives identified on the form of proxy or voting instruction form as proxyholder (including a non-registered shareholder who wishes to appoint themselves as proxyholder) must carefully follow the instructions in the Circular and on their form of proxy or voting instruction form. These instructions include the additional step of registering such proxyholder with our transfer agent, TSX Trust Company, after submitting their form of proxy or voting instruction form. Failure to register the proxyholder with our transfer agent will result in the proxyholder not receiving a Control Number to participate in the Meeting and only being able to attend as a guest.

Hudbay's Board of Directors has fixed the close of business on March 30, 2026 as the record date, being the date for the determination of the registered shareholders entitled to receive notice of and vote at the Meeting or any postponement or adjournment thereof. Shareholders who acquire common shares after March 30, 2026 should make arrangements with the selling shareholder to direct how such common shares will be voted at the Meeting.

Proxies to be used or acted upon at the Meeting or any postponement or adjournment thereof must be deposited with Hudbay's transfer agent, TSX Trust Company, by completing and delivering the form of proxy in accordance with the instructions indicated thereon, no later than 2:00 p.m. (Eastern Time) on May 14, 2026 or 48 hours (excluding Saturdays, Sundays and holidays) before any postponement or adjournment of the Meeting.

On behalf of the Board of Directors, I would like to invite you to attend Hudbay's virtual annual and special meeting of shareholders that will be held on Tuesday, May 19, 2026 at 2:00 pm (ET).

It has been a little over a year since I became Chair of the Board, and I am very pleased with Hudbay's progress over this period. The resilience of our operations and the team's continued execution of our strategy has positioned the company to deliver strong free cash flow, de-risk our long-term growth pipeline and generate significant returns for our shareholders.

Strong Operating Performance in the Face of External Challenges

Hudbay delivered another successful year in 2025 driven by our resilient operating platform and substantial progress advancing the Copper World project. The year, however, was marked by operational success in the face of adversity. Wildfires and adverse weather conditions in Manitoba and social unrest in Peru resulted in temporary interruptions to our operations. I am extremely proud of the job done by everyone in the organization to keep our people and local communities safe, protect our assets and deliver our consolidated copper and gold production guidance for the year at lower-than-expected cash costs despite these external challenges. It is a testament to the team that 2025 is the 11th consecutive year in which Hudbay achieved our annual consolidated copper production guidance and the 5th consecutive year in which we achieved our annual consolidated gold production guidance.

Secured Premier Joint Venture Partner at Copper World

After receiving the Air Quality Permit for Copper World at the beginning of 2025, we formally launched a minority joint venture process that ultimately resulted in the sale of a 30% interest to Mitsubishi Corporation ("Mitsubishi") for US$600 million. The joint venture partnership with Mitsubishi was announced in August 2025 and closed in January 2026. This is a significant milestone for the Copper World project and we are thrilled to have Mitsubishi as a strategic partner moving forward.

Hudbay has achieved the final key financial elements of its three prerequisites plan for the development of the Copper World project with the closing of the joint venture transaction and the achievement of stated deleveraged balance sheet targets ahead of schedule.

Feasibility study activities for Copper World progressed through 2025 and we currently expect to complete the Definitive Feasibility Study (DFS) by mid-2026, followed by a project sanctioning decision. Copper World will be a significant contributor to the U.S. domestic copper supply chain, and once in production, it will add more than 50% growth to Hudbay's consolidated copper production.

Significant Free Cash Flow Generation and Disciplined Capital Allocation Driving Further Debt Reduction

We delivered another year of record financial performance with revenue of US$2.2 billion, adjusted EBITDA of US$1.1 billion and free cash flow of US$388 million in 2025. We continued to exercise financial discipline across our business and made substantial progress to further reduce our debt levels and strengthen our balance sheet in advance of a Copper World sanctioning decision. Through approximately US$102 million of open market purchases of our senior unsecured notes in 2025, together with strong financial performance from our operations, we further reduced our net debt to adjusted EBITDA ratio to 0.4x at the end of 2025 from 0.6x at the end of 2024.

In addition to positioning Hudbay for the potential sanctioning of Copper World, the strength of our balance sheet allows us to strategically allocate capital across the portfolio - including to exploration in Manitoba, throughput enhancements in Peru, optimization and growth projects in British Columbia and pre-feasibility study activities at Mason - and, at the same time, begin to return more capital to shareholders through an increased dividend.

Committed to our Communities and Sustainability Initiatives

Sustainability initiatives are a priority of Hudbay, and the Board's Environmental, Health, Safety and Sustainability ("EHSS") Committee remains committed to overseeing our strategies related to health and safety, environmental and climate-related matters and community and stakeholder relations.

We prioritize strong relationships with Indigenous and other local communities in each of our operating locations and seek to find opportunities to share the economic and social benefits that our operations bring to each region. 2025 was a significant year in this regard. In Manitoba, Hudbay signed its first-ever exploration agreements with the Kiciwapa Cree Nation and the Mosakahiken Cree Nation. In addition, in February 2026, Hudbay received amended permits for the New Ingerbelle expansion project at the Copper Mountain mine and finalized updated participation agreements with the Upper Similkameen Indian Band and the Lower Similkameen Indian Band in British Columbia.

For further information on these initiatives, we encourage shareholders to read our 2025 annual report, which will be published in the second quarter of 2026 and made available on our website at https://www.hudbay.com.

Strong Governance and Board Refreshment

In 2025, we concluded the third party board effectiveness review that commenced in 2024. This involved a report to the Corporate Governance and Nominating Committee that identified key themes that had emerged from the review and recommendations for future action as well as a facilitated workshop with our executive management team. The results of the review were positive, and I believe it has further strengthened the Board and its relationship with our management team.

In addition, we added two new directors to the Board in 2025. John E. F. Armstrong joined the Board in May 2025 and Laura Tyler in September 2025. These appointments reflect Hudbay's ongoing commitment to maintaining a Board of Directors with a broad range of skills, experience and perspectives relevant to the Company's strategy and operations.

In February 2026, the Board learned that Stephen A. Lang, former Chair of the Board, had decided not to stand for re-election at the Meeting due to health reasons. I would like to personally recognize and thank Steve for his years of dedicated service and valuable contributions to Hudbay during this transformative period for the company.

* * *

In closing, I'd like to thank all our people for their contributions to Hudbay's successes in 2025 and recognize the continued strong support of our shareholders and the communities where we operate. We are off to a great start in 2026 as we continue to execute our disciplined growth strategy with the agreement to acquire Arizona Sonoran Copper Company Inc. to create one of the most significant copper districts in North America and reinforce our position as a premier copper growth company. We look forward to continuing our emphasis on shareholder engagement opportunities in the coming year, including at our upcoming meeting on May 19, 2026.

We encourage you all to vote at our 2026 annual and special meeting of shareholders. Sincerely,

‌This management information circular ("Circular") is furnished in connection with the solicitation of proxies by and on behalf of the management of Hudbay Minerals Inc. for use at the Annual and Special Meeting of Shareholders (the "Meeting") to be held on Tuesday, May 19, 2026 at 2:00 p.m. (Eastern Time), or at any postponement or adjournment thereof. The Meeting has been called for the purposes set forth in the Notice of Annual and Special Meeting of Shareholders (the "Notice of Meeting") that accompanies this Circular.

The Meeting will be held as a completely virtual meeting, which will be conducted via live webcast at https://meetings.lumiconnect.com/400-690-725-785. Shareholders will not be able to attend the Meeting in person. A summary of the information shareholders will need to attend and participate at the Meeting online is provided in this Circular.

References in this Circular to "we", "us", "our" and similar terms, as well as references to "Hudbay" and the "Company" refer to Hudbay Minerals Inc. and references to "Board" refer to our board of directors. Unless otherwise indicated, the information in this Circular is given as at April 6, 2026 and all dollar references in this Circular are to Canadian dollars, unless otherwise stated.

This Circular provides the information you need to vote at the Meeting.

If you are a registered holder of our common shares (each, a "Hudbay Share"), a form of proxy has been sent to you that you can use to vote in advance of the Meeting, or you may vote online at our virtual Meeting on May 19, 2026, as described in this Circular. The form of proxy is also available on our website at www.hudbayminerals.com/disclosure-centre, on the website of our transfer agent, TSX Trust Company, at https://docs.tsxtrust.com/2219, and under our profile on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar.shtml.

If you are a non-registered holder of Hudbay Shares and your Hudbay Shares are held by an intermediary (such as a broker or financial institution), you will receive a voting instruction form ("VIF") and should follow the instructions provided with such form.

To reduce printing and mailing costs and waste, Hudbay will use the "notice and access" delivery model ("Notice and Access") to conduct the solicitation of proxies in connection with this Circular. Proxies may also be solicited by telephone or another form of correspondence. The cost of preparing this Circular and other materials relating to the Meeting and the cost of soliciting proxies has been or will be borne by Hudbay. Hudbay will also pay the fees and costs of intermediaries for their services in transmitting proxy-related material in accordance with National Instrument 54-101 - Communication with Beneficial Owners of Securities of a Reporting Issuer ("NI 54-101"). This cost is expected to be nominal.

‌ NOTICE AND ACCESS

Hudbay is using Notice and Access for both registered and non-registered owners of Hudbay Shares, which allows the Company to furnish proxy materials online to shareholders instead of mailing paper copies of such materials. Using Notice and Access, the Company can deliver proxy-related materials by

(i) posting this Circular (and other proxy related materials) on a website other than SEDAR+ and (ii) sending a notice informing shareholders that this Circular and proxy related materials have been posted and explaining how to access such materials (the "N&A Notice").

On or around April 16, 2026, the Company will send to holders of Hudbay Shares as of the record date a notice package containing the N&A Notice and the relevant voting document (a form of proxy or VIF, as applicable). The N&A Notice will contain basic information about the Meeting and the matters to be voted on, instructions on how to access the proxy materials, including this Circular and Hudbay's audited consolidated financial statements for the years ended December 31, 2025 and 2024 and management's discussion and analysis related thereto (together with this Circular, the "Proxy-Related Materials"), an explanation of the Notice and Access process and details of how to obtain a paper copy of the Proxy-Related Materials upon request at no cost.

‌The Proxy-Related Materials are available on our website at www.hudbayminerals.com/disclosure-centre, on the website of our transfer agent, TSX Trust Company, at https://docs.tsxtrust.com/2219, and under our profile on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar.shtml. Shareholders who want to receive a paper copy of the Proxy-Related Materials or who have questions about Notice and Access may contact our transfer agent, TSX Trust Company, by toll-free telephone at 1-866-600-5869 or by email at [email protected].

approval of a non-binding advisory resolution on executive compensation.

The record date for the Meeting is March 30, 2026. Our transfer agent has prepared a list, as of the close of business on the record date, of the registered shareholders. A holder of Hudbay Shares whose name appears on such list is entitled to vote the shares on such list at the Meeting. Each Hudbay Share entitles the holder to one vote on each item of business identified in the Notice of Meeting.

Non-Registered Shareholders

It is possible that your Hudbay Shares are registered in the name of an intermediary, which is usually a trust company, securities broker or other financial institution. If your Hudbay Shares are registered in the name of an intermediary, you are a non-registered shareholder. Your intermediary is entitled to vote the Hudbay Shares held by it and beneficially owned by you as of the record date. However, your intermediary must first seek your instructions as to how to vote your Hudbay Shares or otherwise make arrangements so that you may vote your Hudbay Shares directly. An intermediary is not entitled to vote the Hudbay Shares held by it without written instructions from the beneficial owner. As a non-registered shareholder, you may vote your Hudbay Shares through your intermediary or online at the virtual Meeting by taking the appropriate steps described below, which are the same for objecting beneficial owners ("OBO") and non-objecting beneficial owners ("NOBO") of Hudbay Shares. You are an OBO if you have not allowed your intermediary to disclose your ownership information to us. You are a NOBO if you have provided instructions to your intermediary to disclose your ownership information to us.

In order to appoint yourself as proxyholder, you should follow the instructions on the VIF and, in so doing, specify your own name as the person whom you are appointing as proxy for the purposes of voting your Hudbay Shares. You are reminded that any voting instructions should be communicated to your intermediary in accordance with the procedures set out in the VIF well in advance of the May 14, 2026 deadline for the receipt of proxies.

If you are a non-registered shareholder and you would like to ask a question at the Meeting, login using the TSX Control Number you received when you appointed yourself a proxyholder and registered with our transfer agent, TSX Trust Company. Questions can be submitted at any time during the Q&A session up until the Chair closes the session by using the messaging icon. Type your message within the chat box in the top portion of the messaging screen. Once you are happy with your message click the send button.

Non-registered shareholders who have not duly appointed themselves as proxyholder will not be able to vote or ask questions at the Meeting, however such non-registered shareholders may still attend the Meeting as guests through the live webcast at https://meetings.lumiconnect.com/400-690-725-785.

NOBOs and OBOs

NOBOs and OBOs should carefully review the instructions provided to them by their intermediary regarding how to provide voting instructions or how to obtain a proxy with respect to their Hudbay Shares. Such non-registered shareholders may also wish to contact their intermediary directly in order to obtain instructions regarding how to vote Hudbay Shares that they beneficially own. The Proxy-Related Materials will be sent by the Company indirectly to NOBOs and the Company intends to pay for intermediaries to deliver proxy-related materials and Form 54-101F7 (the request for voting instructions) to OBOs, in accordance with NI 54-101.

Technical Support

‌Shareholders who experience any technical issues on the Lumi platform either prior to or during the virtual meeting on May 19, 2026 should promptly contact Lumi directly, our virtual meeting provider, by sending an email to [email protected] or visiting Lumi's support portal at support.lumiglobal.com for common troubleshooting information.

VOTING YOUR COMMON SHARES BY PROXY

If neither you nor your proxyholder gives specific instructions, your Hudbay Shares will be voted as follows:

Appointing a Proxyholder

A proxyholder is the person you appoint to act on your behalf at the Meeting (including any postponement of the Meeting or continuation after an adjournment of the Meeting) and to vote your Hudbay Shares. You have the right to appoint a person or company other than the Hudbay representatives named as proxyholders to represent you at the Meeting. To do so, simply fill in the proxyholder's name in the blank space provided on the enclosed form of proxy. If you leave the space in the form of proxy blank, the persons designated in the form, who are our Board Chair and our President and Chief Executive Officer, respectively, are appointed to act as your proxyholder.

Shareholders who wish to appoint a person other than the Hudbay representatives identified on the form of proxy or VIF as proxyholder (including a non-registered shareholder who wishes to appoint themselves as proxyholder) must carefully follow the instructions in the Circular and on their form of proxy or VIF. These instructions include the additional step of registering such proxyholder with our transfer agent, TSX Trust Company, by emailing [email protected] the "Request for Control Number" form, which can be found at https://tsxtrust.com/resource/en/75, after submitting their form of proxy or VIF.

Revoking your Proxy

If you submit a form of proxy, you may revoke it at any time before it is used by doing any one of the following:

you may send another form of proxy (with a later date) to our transfer agent, TSX Trust Company, but it must reach the transfer agent no later than 2:00 p.m. (Eastern Time) on May 14, 2026 or 48 hours (excluding Saturdays, Sundays and holidays) before any postponement or adjournment of the Meeting;

you may deliver a signed written statement, stating that you want to revoke your form of proxy, to our Corporate Secretary no later than the last business day preceding the Meeting or any postponement or adjournment of the Meeting, by mail to Hudbay Minerals Inc., 25 York Street, Suite 800, Toronto, Ontario M5J 2V5, Attention: Corporate Secretary; or

you may revoke your form of proxy in any other manner permitted by law.

If as a registered shareholder you are using your control number to log in to the Meeting, you will be provided the opportunity to vote by online ballot at the appropriate time on the matters put forth at the Meeting.

‌Only registered shareholders have the right to revoke a proxy. Non-registered shareholders who wish to change their vote must make appropriate arrangements directly with their respective intermediaries. Late proxies may be accepted or rejected by the Chair of the Meeting in his discretion, and the Chair is under no obligation to accept or reject any late proxy.

ADDITIONAL MATTERS PRESENTED AT THE MEETING

The form of proxy or VIF confers discretionary authority upon the persons named as proxyholders therein with respect to any amendments or variations to the matters identified in the Notice of Meeting and with respect to other matters that may properly come before the Meeting or any postponement or adjournment thereof. As of the date hereof, our management is not aware of any matters to be considered at the Meeting other than the matters described in the Notice of Meeting, or any amendments or variations to the matters described in such notice.

If you sign and return the VIF, your Hudbay Shares will be voted in accordance with your instructions and, with respect to any matter presented at the Meeting, or at any postponement or adjournment thereof, in addition, or as an amendment or variation to the matters described in the Notice of Meeting, in accordance with the discretionary authority provided therein.

You have the right to appoint a person or company other than the Hudbay representatives named as proxyholders to represent you at the Meeting. If you sign and return the form of proxy and do not appoint a proxyholder by filling in a name, the Hudbay representatives named as proxyholders will vote in their best judgment.

‌ VOTING SHARES AND PRINCIPAL HOLDERS

The Hudbay Shares are the only shares which entitle shareholders to vote at the Meeting. The holders of Hudbay Shares are entitled to one vote per Hudbay Share. The presence of at least two people holding or representing by proxy at least 25% of the total number of votes attached to the issued common shares entitled to vote at the Meeting is necessary for a quorum at the Meeting.

As at March 30, 2026, the record date for the Meeting, 397,196,119 Hudbay Shares were issued and outstanding.

To the knowledge of the directors and executive officers of Hudbay, based upon filings made with Canadian and United States securities regulators on or before the date of this Circular, there are no persons as of April 6, 2026 who beneficially own, or control or direct, directly or indirectly, voting securities carrying more than 10% of the voting rights attached to any class of our voting securities.

The solicitation of proxies by Hudbay is not subject to the requirements of Section 14(a) of the United States Securities Exchange Act of 1934, as amended (the "U.S. Exchange Act"), by virtue of an exemption applicable to proxy solicitations by "foreign private issuers" as defined in Rule 3b-4 promulgated under the U.S. Exchange Act. Accordingly, this Circular has been prepared in accordance with the applicable disclosure requirements in Canada. Shareholders in the United States should be aware that such requirements are different than those of the United States applicable to proxy statements under the U.S. Exchange Act.

‌ 1. FINANCIAL STATEMENTS

‌Our audited consolidated financial statements for the years ended December 31, 2025 and 2024 and the auditor's report thereon will be presented at the Meeting.

2. ELECTION OF DIRECTORS

Our articles provide that the Board may consist of a minimum of six and a maximum of thirteen directors.

On the recommendation of the Corporate Governance and Nominating ("CGN") Committee, the Board has determined to nominate each of the nine persons listed below for re-election as a director at the Meeting. (See "Nominees for Election as Directors" below).

In late 2025, after having completed the Board effectiveness review and the annual Board survey, the CGN Committee asked the Board Chair to have a discussion with each of the individual directors to better understand potential retirement plans and to determine if any of them did not wish to stand for re-election at the Meeting. At the time of those discussions, all of the incumbent directors expressed a desire to stand for re-election at the Meeting. However, in February 2026, Stephen A. Lang advised the Board Chair that he had decided not to stand for re-election due to health reasons and the Board Chair communicated this to the Chair of the CGN Committee.

With this feedback, the CGN Committee considered the size, skills and composition of the Board and decided that it may be desirable to appoint an additional director to the Board later in 2026 that could further strengthen the Board and its Technical Committee following Mr. Lang's departure. At the same time, the CGN Committee determined that, with the refreshment of the Board over the past five years, the nine nominee directors had the skills and experience to effectively oversee the Company's business and strategy.

Hudbay wishes to thank Mr. Lang for his years of dedicated service and his valuable contributions to the Company. Mr. Lang previously served as Hudbay's Board Chair and is currently a member of the Technical Committee and Audit Committee.

Each director elected to the Board at the Meeting shall hold office until the close of the next annual meeting of shareholders or until a successor has been elected or appointed in accordance with our articles and by-laws.

Majority Voting Requirement and Advance Notice By-Law

As a corporation organized under the Canada Business Corporations Act (the "CBCA"), by statute, each of our directors must be elected by a majority of the votes cast for them. This rule only applies to an uncontested election of directors, being an election where the number of director nominees does not exceed the number of directors to be elected and in respect of which no proxy material is circulated in support of one or more nominees who are not part of the slate supported by the Board.

In addition, our Advance Notice By-Law (a copy of which is available on SEDAR+ at https://www.sedarplus.ca), ensures that all shareholders receive adequate notice of director nominations and sufficient time and information regarding nominees to make informed voting decisions. The Advance Notice By-Law fixes a deadline by which holders of record of Hudbay Shares must submit director nominations to our secretary prior to any annual or special meeting of shareholders and sets forth the specific information that a shareholder must include in the written notice for an effective nomination to occur.

‌ 3. APPOINTMENT OF AUDITOR

Unless authority to do so is withheld, the persons named in the accompanying form of proxy intend to vote FOR the appointment of Deloitte LLP ("Deloitte"), as our auditor until the close of our next annual meeting of shareholders and the authorization of the Board, upon the recommendation of the Audit Committee, to fix the remuneration of the auditor.

Deloitte was first appointed as our auditor on May 6, 2005. For the year ended December 31, 2025, Deloitte was paid $3,334,419 for audit services, $202,298 for audit-related services and $140,000 for other services. Deloitte was not paid any fees for tax-related services in 2025. All non-audit services provided by Deloitte are subject to pre-approval by our Audit Committee.

Additional information regarding the compensation of Deloitte is contained in our Annual Information Form for the year ended December 31, 2025 under the heading "Audit Committee Disclosure - Remuneration of Auditor". Our Annual Information Form may be found on our website at www.hudbay.com, on SEDAR+ at www.sedarplus.ca and as an exhibit to our Form 40-F on EDGAR at www.sec.gov/edgar.shtml.

‌ 4. SAY ON PAY ADVISORY VOTE

Hudbay's compensation model is designed to: (i) provide competitive compensation to attract and retain talented high-achievers and appropriately incent them to achieve our strategic and operational objectives; and (ii) align the interests of our executives with the long-term interests of our shareholders. Detailed disclosure of Hudbay's executive compensation program can be found under the heading "Statement of Executive Compensation" found later in this Circular.

The Board has adopted a non-binding advisory vote relating to executive compensation to solicit feedback from shareholders on our approach to executive compensation. As a formal opportunity to provide their views on the disclosed objectives of Hudbay's compensation model, shareholders are asked to review and vote in a non-binding, advisory manner, on the following resolution:

"BE IT RESOLVED, on an advisory basis and not to diminish the role and responsibilities of the Board, that the shareholders accept the approach to executive compensation disclosed in the Circular."

As an advisory vote, the resolution will not be binding on the Board. However, the Compensation and Human Resources Committee and the Board will take the results of the vote into account, as appropriate, when considering future compensation policies, procedures and decisions, all of which are to be consistent with Hudbay's compensation philosophy (see the "Statement of Executive Compensation" for details).

Hudbay will disclose the results of the Say-on-Pay advisory vote as part of its report on voting results for the meeting.

Our Board believes that sound corporate governance practices are essential to the effective management of Hudbay and the protection of its employees, shareholders and other stakeholders. Our Board oversees the management of our business and affairs with a view to ensuring we uphold Hudbay's purpose and mission statements and that shareholder value is enhanced without compromising our commitment to the highest standards of ethical conduct.

Our Board has adopted corporate governance policies and procedures to assist it in fulfilling this oversight role. The Board fulfills its mandate directly and through its Committees. The directors are kept informed of our operations at regular and special Board and Committee meetings as well as through reports and discussions with management. We believe Hudbay is best served by a Board that functions independently of management and is informed and engaged.

In addition, our CGN Committee annually reviews the performance of our Board, its Committees and our directors and recently engaged a third party consultant to carry out a comprehensive board effectiveness review that concluded in mid-2025 (as further described in this Statement of Corporate Governance).

Our CGN Committee also regularly monitors our corporate governance policies and procedures with a view to ensuring that they continue to guide the Board and management to act in the best interests of Hudbay and our stakeholders.

Our Corporate Governance Guidelines (including the Board Charter) are set out in Schedule "A" to this Circular and can be viewed at our website at https://www.hudbay.com. The following is a description of Hudbay's corporate governance practices as approved by the Board.

Highlights of Hudbay's Corporate Governance Practices

Board Independence:

The Chair and all of Hudbay's directors, other than Mr. Kukielski, are independent; the Committees of the Board are composed entirely of independent directors; and independent directors meet without management present at all regular Board and Committee meetings.

Gender and Diversity:

Hudbay has a written policy for the identification and nomination of director candidates who are diverse in all respects, including gender, and the policy sets a target for the Company to have at least 30% female directors on the Board.

Majority Voting and Advance Notice:

Hudbay is subject to a statutory majority voting requirement for uncontested director elections and has adopted an advance notice by-law that provides advance notice requirements for director elections.

Board Composition and Skills:

The Board has developed a nuanced skills matrix that is used by the CGN Committee to evaluate and monitor the composition and strengths of the Board as well as the skills and experience that should be sought in new director nominees. The Board skills matrix was recently updated,

following a comprehensive review by the CGN Committee.

Ethical Business Conduct:

Hudbay is committed to conducting business honestly, ethically and fairly and has adopted a Code of Business Conduct and Ethics, a Global Supplier Due Diligence Policy and Supplier and Customer Codes of Conduct and regularly carries out certification and training programs with

regard to its key compliance policies.

Highlights of Hudbay's Corporate Governance Practices

Disclosure Policy:

Hudbay has a Disclosure Policy that requires the company to provide timely disclosure of material

information in a manner that is broadly accessible on a non-exclusionary basis. Hudbay's

Disclosure Committee reviews and supervises the preparation of all public disclosure and is responsible for ensuring that information is disclosed in accordance with the Disclosure Policy.

Management:

Hudbay has a formal risk management program whereby the Board and its Committees have each been assigned responsibility for the oversight of certain of the principal risks facing the company and receive quarterly reporting from management on the monitoring and management of those risks. In addition, Hudbay has an internal audit function that is responsible for establishing a flexible, risk-based annual audit plan and reports to the Audit Committee.

Shareholder Engagement:

The Board is committed to a dialogue with our shareholders and other stakeholders about our corporate governance policies, sustainability strategy, executive compensation program and other matters of interest and has adopted a Shareholder Engagement Policy with this in mind.

Planning:

Hudbay's Board has a formal process for succession planning for its executive officers (including the CEO) that is overseen and reported on by the Compensation and Human Resources Committee.

ESG Oversight and Governance:

The EHSS Committee has been delegated oversight authority over the Company's sustainability strategy, including climate-related risks, opportunities and targets and community and stakeholder relations, and other Committees have been delegated oversight over other ESG matters such as

tailings and corporate governance.

Board and Committee Evaluations:

A formal evaluation of the performance and effectiveness of the Board and its Committees is carried out annually under the supervision of the CGN Committee.

Related Party Transactions

The CGN Committee is responsible for reviewing all related party transactions, regardless of whether such transactions are reportable under applicable securities regulations.

BOARD OF DIRECTORS: THE ROLE OF THE BOARD

The Board mandate has been formalized in a written Board Charter that sets out specific responsibilities, which include:

satisfying itself as to the integrity of the Chief Executive Officer and other senior officers and that the Chief Executive Officer and other senior officers create a culture of integrity throughout the Company;

reviewing and approving the strategic plan and business objectives that are submitted by senior management and monitoring the implementation by senior management of the strategic plan;

reviewing the principal risks for Hudbay and overseeing, with the assistance of the Audit Committee, the implementation and monitoring of appropriate risk management systems and monitoring of risks;

ensuring, with the assistance of the CGN Committee, the effective functioning of the Board and its Committees in compliance with applicable corporate governance requirements, and that such compliance is reviewed periodically by the CGN Committee;

ensuring internal controls and management information systems are in place and are evaluated and reviewed periodically on the initiative of the Audit Committee;

assessing the performance of senior management, including monitoring the establishment of appropriate systems for succession planning (including the development of policies and principles for Chief Executive Officer selection and performance reviews) and periodically monitoring the compensation levels of the members of senior management based on the determinations and recommendations made by the Compensation and Human Resources Committee;

ensuring we have in place a policy for effective communication with shareholders, other stakeholders and the public generally; and

reviewing and, where appropriate, approving the recommendations made by the various Committees, including the selection of nominees for election to the Board, appointment of directors to fill vacancies on the Board, appointment of members of the various Committees and establishing the form and amount of director compensation.

Independence

For a director to be considered independent under the policies of the Canadian Securities Administrators, he or she must have no direct or indirect material relationship with the Company, being a relationship that could, in the view of the Board, reasonably be expected to interfere with the exercise of his or her independent judgment, and must not be in any relationship deemed to be not independent pursuant to such policies. To assist in determining the independence of directors for purposes that include compliance with applicable legal and regulatory requirements and policies, the Board has adopted certain categorical standards, which are part of our Corporate Governance Guidelines.

With the assistance of the CGN Committee, the Board has considered the relationship to Hudbay of each of the nominees for election by the shareholders and has determined that eight of our nine directors nominated for election at the Meeting are independent. The following table sets out the relationship of the nominees for election as directors to Hudbay.

Restrictions on Board Membership at Other Entities

Our Corporate Governance Guidelines prohibit our directors from having more than one interlocking directorship (being one in which two or more of our directors sit together on the board of another reporting issuer), without the approval of our CGN Committee. None of our director nominees have an interlocking directorship and sit together on the board of another reporting issuer.

Our Corporate Governance Guidelines do not restrict the number of public company boards on which our directors may sit. However, our Code of Business Conduct and Ethics requires that the Chair approve any other directorships held by our directors. In addition, directors are expected to devote the required time and effort to discharge their obligations as members of the Board. Currently, only one of our director nominees sits on the boards of more than two other reporting issuers.

For more information about the nominees for election at the Meeting, including a listing of the reporting issuers on whose boards our director nominees sit, see above under the heading "Election of Directors -Nominees for Election as Directors".

Independent Chair

In addition to having a majority of independent directors, the Board has adopted a variety of procedures to allow for the independent functioning of the Board from management. Those procedures include having a Chair who is an independent director with a formal mandate to assist the Board in fulfilling its duties effectively, efficiently and independent of management.

The responsibilities of the Chair include acting as a liaison between the Board and the Chief Executive Officer, communicating to the Chief Executive Officer the Board's feedback on his/her performance and working with the Chief Executive Officer to ensure that the Board is appropriately involved in approving and supervising Hudbay's strategy. The Chair is also responsible for ensuring open communication between the Board and senior management, leading efficient and inclusive discussions among the directors and recommending procedures to enhance the work of the Board and cohesiveness among directors. The full position descriptions of the Board Chair and the Chair of each of the Board's Committees, including a complete list of their responsibilities, which have been approved by the Board, are available on our website at https://www.hudbay.com.

CEO Position Description

The Board has approved a position description for the Chief Executive Officer (available on our website at https://www.hudbay.com), which delegates to the CEO the responsibility for providing strategic leadership and vision by working with the Board and the senior management team to establish, implement and oversee our long-range goals, strategies, plans and policies, subject to the direction and oversight of the Board. The Chief Executive Officer advises the Board on a timely basis of management's current and proposed courses of action, and also reports less formally to the Board through discussions with the Chair and other members of the Board. The Board exercises its responsibility for oversight through the approval of all material decisions and initiatives affecting Hudbay.

Board Composition and Skills

The CGN Committee, which is composed entirely of independent directors, assists the Board in evaluating the composition and skills of our Board, including potential areas that could be strengthened in the future. Among other things, the CGN Committee considers the size and effectiveness of the Board, identifies skills and areas of expertise that may be desirable to add to the Board in the context of the Company's business and strategy, assists the Board by identifying individuals qualified to become members of the Board, and recommends to the Board nominees for election to the Board in annual meetings and directors to be appointed to each Committee and as the Chair of each Committee. These activities are informed, in part, through a formal Board evaluation process that is carried out annually by the CGN Committee and included the results of a third-party board effectiveness review completed in 2025, as described under "Board and Committee Evaluations" below, as well as a self-assessment of our directors against a skills matrix.

In assessing individual director nominees, the CGN Committee considers, in addition to the skills and expertise highlighted in the Board skills matrix, the following criteria: (i) judgment and character; (ii) diversity of the Board, including diversity of gender, viewpoints, backgrounds, experiences and other demographics (and the target for at least 30% women directors as described in our Diversity Policy below); and (iii) the extent to which the interplay of a nominee's expertise, skills, knowledge and experience with that of other members of the Board will build a Board that is effective, collegial and responsive to our needs.

The Board's skills matrix is used to identify and evaluate the competencies and skills of our directors based on the individual experience and background of each director and to identify potential areas for strengthening the Board. In late 2024, the CGN Committee undertook a comprehensive review of the categories of skills and experiences that were included in the Board's skills matrix in the context of the Company's business and strategy. Following its review, the CGN Committee recommended certain updates to the skills matrix to reflect the skills and experiences that it considered most important to the effectiveness of the Board and the Board's role in overseeing the execution of Hudbay's business plans and strategy and, in 2025, the CGN Committee re-affirmed the categories in the skills matrix. All of Hudbay's directors have self-assessed against the skills matrix and the results of their self-assessment, together with other relevant considerations, are utilized by the CGN Committee to identify those skills and experiences that are most relevant to Board succession and renewal.

The following Board skills matrix sets out the specific skills and expertise of each director nominee and the current strengths of the Board as a whole.

Board and Committee Evaluations

The CGN Committee is responsible for conducting a formal evaluation of the performance and effectiveness of the Board and its Committees on an annual basis.

In 2024, the CGN Committee engaged an independent consulting firm to carry out a comprehensive board effectiveness review, as part of an enhanced Board evaluation process. The board effectiveness review involved a review of the Board's skills matrix, completion of a board review questionnaire, interviews with each director and members of senior management, individual director feedback and a report to the CGN Committee that identified key themes that had emerged from the review and recommendations for future action, which the CGN Committee shared with the Board. The final phase of the review involved a board effectiveness workshop that included all of our directors and management's executive committee, which took place in mid-2025.

After having completed a comprehensive board effectiveness review earlier in the year, the CGN Committee decided to distribute an anonymous Board survey to the directors at the end of 2025 to complete its annual Board evaluation process. The survey included questions regarding the effectiveness of the Board and its committees and measured progress against the questionnaire that formed part of the board effectiveness review. The CGN Committee shared the results of the Board survey with the Board and discussed the key themes that had emerged.

In addition to the CGN Committee's annual Board evaluation, members of each Committee are provided questionnaires that deal with the performance of the Committee and its Chair and ask the Committee members to raise any matters of concern. The results of these questionnaires are discussed during in camera sessions of the Committees and any relevant findings are reported to the Chair of the CGN Committee and/or Board Chair.

Age and Term Limits; Focus on Board Renewal

We do not have age or term limits for service on the Board. Instead, the Board focuses on monitoring the effectiveness and composition of the Board, including considerations related to Board dynamics, individual director performance, any skills gaps and the need for renewal and diversity. As part of the Board's annual evaluation process, the CGN Committee receives feedback on the performance of each individual director, opportunities for improved Board effectiveness, directors' potential retirement plans and considerations related to director succession planning and Board renewal.

Since the beginning of 2022, five new directors have joined Hudbay's Board, including, most recently, John E. F. Armstrong, who was elected at the 2025 Meeting in May 2025, and Laura Tyler who was appointed to the Board in September 2025. In addition, following Stephen A. Lang's recent decision not to stand for re-election at the Meeting due to health reasons, the CGN Committee considered the size, skills and composition of the Board and decided that it may be desirable to appoint an additional director to the Board later in 2026 that could further strengthen the Board and its Technical Committee. These appointments and considerations reflect Hudbay's commitment to Board renewal and effectiveness, and focus on maintaining a Board with a broad range of skills, experience and perspectives relevant to the Company's strategy and operations.

Related Party Transactions

Our Corporate Governance Guidelines delegate responsibility to the CGN Committee to review transactions between the Company and any related party, regardless of whether the transactions are reportable pursuant to securities regulations. After considering advice from the CGN Committee, the Board shall review, and, if appropriate, approve or ratify, such related party transactions. For purposes of the guidelines, a "related party transaction" is any transaction in which the Company was or is to be a participant and in which any related party has a direct or indirect material interest, other than transactions that (i) are available to all employees generally, (ii) involve compensation of executive officers or directors duly authorized by the appropriate Board committee, or (iii) involve reimbursement of expenses in accordance with the Company's established policies.

Board and Committee Meetings and Attendance

The Board meets a minimum of four times per year and as otherwise required. Most Committees meet quarterly, or more frequently as deemed necessary by the applicable committee. The frequency of meetings and nature of each meeting agenda depend on the business and affairs that Hudbay faces from time to time.

The following table provides details regarding the attendance of our nine incumbent director nominees at Board and committee meetings held during the year ended December 31, 2025:

In Camera Sessions without Management

The independent members of the Board meet without management in in camera sessions at all regular Board meetings. During the year ended December 31, 2025, the Board held in camera sessions of the independent directors at nine Board meetings. In addition, all of the Committees hold in camera sessions without the presence of management at each regular meeting.

Director Orientation and Continuing Education

Senior management, working with the Board, provides appropriate orientation and education for new directors to familiarize them with Hudbay and its business. New directors are provided with a comprehensive set of resources which includes, among other things, information about the duties and obligations of directors, copies of Hudbay's Corporate Governance Guidelines and Board Charter, Committee charters and other key compliance and governance policies, descriptions of our organizational structure, strategic plans, compensation plans, investor presentations and copies of our most recent core public disclosure documents. New directors are expected to meet with members of senior management, the Board Chair and the Chairs of the Committees on which they will serve as part of their orientation process, and are also invited to attend site visits at our key properties.

Our directors are encouraged to attend third-party educational programs and our Board members receive a membership with the Institute of Corporate Directors, where they have access to educational materials and are invited to training seminars throughout the year. In addition, we frequently include a director education topic on the agenda at Board and Committee meetings, site visits and other events. This typically involves presentations to the Board by members of management and third-party advisors in respect of our business and operations, corporate development, strategy, legal and regulatory matters, ESG topics and industry trends and practices.

The following were among the educational and strategic presentations made to our Board and its Committees in 2025:

‌STRATEGIC PLANNING

‌The Board recognizes that one of its primary responsibilities is to provide direction and oversight to management in pursuit of the Company's strategy. Senior management, led by the CEO, is responsible for presenting strategy plans to the Board for approval, and pursuing strategic opportunities and business objectives that align with Hudbay's corporate strategy. The Board recognizes that consideration of the Company's strategy and strategic opportunities must be an ongoing conversation with management and company strategy is discussed with management at every regular Board meeting. In addition, the Board holds an annual meeting that focuses solely on strategy.

RISK MANAGEMENT

A key element of the Board's responsibilities is to review the principal risks for the Company and oversee, with the assistance of the Audit Committee, the implementation and monitoring of appropriate risk management systems and the monitoring of risks.

The Board provides overall governance of the risk management function by:

approving the Company's risk management policy;

setting the risk appetite associated with Hudbay's strategy and corporate objectives;

ensuring, with the assistance of the Audit Committee, that senior management has instituted and is operating a system that identifies, assesses, mitigates and communicates the principal risks the Company faces; and

monitoring, with the assistance of the Board's committees, the management of the Company's principal risks.

The Audit Committee oversees the design and ongoing review of the Company's risk management system. In this capacity, the Audit Committee is responsible for reviewing and overseeing our risk management policy and approving a formalized, disciplined and integrated enterprise risk management ("ERM") process that is developed by senior management and, as appropriate, the Board and its Committees, to monitor, manage and report principal risks.

Each of the Board's committees is responsible for monitoring the critical risks assigned to it by the Board, periodically reviewing with management how those risks are being managed (including the actions that have been taken by management to mitigate the risks) and communicating findings to the full Board. By way of example, cyber security risks are overseen by the Audit Committee, as it has responsibility for reviewing and monitoring the information technology risks facing the Company, and climate-related risks are overseen by the EHSS Committee, as it has responsibility for monitoring sustainability-related risks.

Oversight of the Company's current Tier 1 Risks is allocated among the Board and its committees as follows:

Conducting business in accordance with the risk appetite set by the Board,

Integrating risk management into strategic business planning, budget and resource allocation, operating performance, and human resources, financial and compliance processes, and

Actively monitoring and managing principal business risks.

In addition, our Director, Internal Audit is responsible for establishing a flexible, risk-based annual internal audit plan to determine the priorities of the internal audit function, consistent with Hudbay's strategic plan and aligned with the ERM program, including but not limited to risk registers and risk appetite and tolerance levels. The Audit Committee approves the annual internal audit plan.

DIVERSITY POLICY AND INITIATIVES

Our Corporate Governance Guidelines (a copy of which can be found at Schedule "A") include a written policy for the identification and nomination of director candidates who are diverse in many respects, including gender. The Board has also approved a standalone written Diversity Policy to supplement our Corporate Governance Guidelines.

Our Diversity Policy seeks to ensure a diverse representation of women and other designated groups (Indigenous peoples, persons with disabilities and visible minorities) among the members of our Board and senior management and includes a target for the Company to have at least 30% women directors on the Board. This policy confirms the Board's commitment to diversity and inclusion as part of our core values and to setting a "tone at the top" that leads to greater diversity on the Board, in senior management and across the organization.

The CGN Committee is responsible for ensuring the objectives of our Diversity Policy are applied when recommending changes to the composition of the Board. Consistent with the objectives of our Diversity Policy, 44% of the director nominees proposed by the CGN Committee for election this year are women.

Pursuant to our Diversity Policy, in assessing individual director nominees, the CGN Committee considers, among other things, relevant skills and expertise, judgment and character, diversity (including diversity of gender, viewpoints, backgrounds, experiences and other demographics, such as the representation of Indigenous peoples, persons with disabilities and visible minorities), and the extent to which the interplay of an individual's expertise, skills, knowledge and experience with that of other members of the Board will build a board that is effective, diverse, collegial and responsive to the needs of the Company. In addition, when engaging search firms to identify candidates for the Board, the CGN Committee is responsible for ensuring the objectives of our Diversity Policy are applied. The CGN Committee may, in certain circumstances, instruct a search firm to focus on identifying only those candidates from one or more underrepresented groups that have the specific skills and expertise required to complement the current composition of the Board.

Although we do not have specific targets regarding the representation of women and other designated groups among our senior management team, the CEO is tasked with ensuring the objectives of our Diversity Policy are applied with respect to senior management positions. We remain committed to diversity and inclusion as part of our core values as we seek to attract and retain talent for the organization, while recognizing that, ultimately, all hiring and promotion decisions must be merit based to ensure our future success.

Corporate and Business Unit People Initiatives

Hudbay's corporate office supports the Company's core values of having a diverse, equitable and inclusive workplace and has formed a committee that has arranged for targeted charitable corporate donations and worked collaboratively with the HR group and business units to develop strategic priorities and advance certain initiatives. These initiatives have included panel discussions with senior leaders, employee engagement and culture surveys and guest speakers. Going forward, the strategic focus will be on continued employee communications and engagement, following through on our commitment to the Mining Association of Canada's Towards Sustainable Mining ("TSM") Equitable, Diverse and Inclusive Workplaces Protocol, supporting our business units with the implementation of their own people initiatives and measuring our progress toward achieving our diversity and inclusion objectives.

The "Nuestras Voces" (Our Voices) program at our Peru Business Unit aims to support the overall people strategy goal of creating a more diverse, equitable and inclusive organization, and increasing the percentage of women in the workforce to 30%. One initiative launched under this program - Hatun Warmi (which translates from Quechua to "Great Women") - is aimed exclusively at providing women from the local communities near the Constancia mine with the training necessary to obtain an operator's license for mining equipment.

Hudbay has two trainee classes from the Hatun Warmi program who completed their training, with a total of 23 women who have graduated. To date, 15 of those women have joined Hudbay's permanent workforce in Peru. Notably, the first class, which began by operating auxiliary equipment such as excavators and small loaders, has now transitioned to operating mine haul trucks. This represents a significant milestone in their professional development, achieved through the specialized training and capacity-building provided by Hudbay. Meanwhile, the women of the second class are currently gaining experience in auxiliary equipment. They are being given the opportunity to master various types of auxiliary machinery used at the site, further enhancing their skills to eventually transition to haul trucks in the future.

Another successful initiative was the community co-op concentrate transport program, which has resulted in approximately 45% of our concentrate production from Constancia now being transported by the local communities.

Hudbay's Manitoba Business Unit, in partnership with the Northern Manitoba Sector Council, launched the "Mining Fundamentals" program in 2024, a course designed to develop local talent and strengthen workforce pipelines in Northern Manitoba. This program addresses the growing need for skilled mining professionals while creating meaningful opportunities in our neighbouring Indigenous communities. The first cohort from 2024 included ten participants, all from Opaskwayak Cree Nation and Mosakahiken Cree Nation, who engaged in safety training, underground operations, and mine rescue overview, demonstrating exceptional dedication throughout their learning journey. Nine of the program graduates accepted full-time positions at our Lalor mine. The second cohort from 2025 included 10 participants from Norway House Cree Nation and Moose Lake First Nation. Of these participants nine accepted full-time positions with Hudbay. This program marks an important milestone in Hudbay's commitment to sustainable community development.

Furthermore, each of our sites continues to prioritize cultural awareness training and employment opportunities for local communities and Indigenous groups, ensuring our workforce mirrors the demographics of our operational areas and is in alignment with our diversity and inclusion objectives. Many of these important initiatives are highlighted in our Annual Report (see "Sustainability Reporting").

Measuring our Success

Hudbay intends to measure the effectiveness of its people policies and initiatives by monitoring the increase in diversity on the Board and in senior management positions over time, assessing the experience of different groups of our employees through the results of our engagement surveys and measuring the participation of different groups of our employees in key business processes.

The Board and senior management recognize the need for increased diversity among senior management, including greater representation of female and other designated groups. Consideration of executive appointments occurs in the context of our succession planning framework, which identifies potential successors for our current executives. While we are committed to ensuring diverse candidates are considered for executive roles, this will best be achieved by bringing in diverse and talented people to all levels of our organization and ensuring that they are given every opportunity to flourish and advance within the organization. Underscoring this commitment, in 2025, we promoted Candace Brûlé to Senior Vice President, Capital Markets and Corporate Affairs and successfully enhanced our regional leadership team through the appointment of Audra Walsh, as our Vice President of the South America Business Unit.

In furtherance of this goal, in 2022, we created a two-year development program for those employees who have consistently performed at a high level and have the potential to move into a more senior leadership role in the next two years. The first cohort graduated in December 2024 with one-third female representation, and we maintained this level of diverse participation in the second cohort that commenced in 2025.

Building on this momentum, we have continued our investment in an external development program exclusively focused on building female leaders in the mining industry. For 2026, we have sponsored five female leaders from across the business to participate in this year-long program, which combines face-to-face and virtual sessions to connect and develop women in historically male-dominated industries. This commitment is yielding tangible results, as participants who have completed the program have already transitioned into new, larger roles or are being strategically developed for future progression within the organization.

SUCCESSION PLANNING FOR EXECUTIVE OFFICERS

Hudbay has a structured process for succession planning for its executive officers. The Chief Executive Officer, with the assistance of our Senior Vice President, Legal and Organizational Effectiveness, is responsible for overseeing the succession planning process. As part of this process, an employee's manager-once-removed (the manager of the employee's manager) is accountable for planning, assessing and monitoring the identification and development of successors to management and other key roles. Results are compiled by the Human Resources group and discussed among senior management in the context of retention risks, talent development and potential retirement or departures of key personnel, following which a formal succession plan is prepared and reported to the Compensation and Human Resources Committee and the Board.

The Compensation and Human Resources Committee is responsible for overseeing a succession plan for the CEO and making recommendations to, and seeking validation from, the Board regarding its CEO succession planning. Among other things, the Compensation and Human Resources Committee and Board consider the CEO's tenure and potential retirement plans, internal candidates with long-term potential to serve as Hudbay's CEO and oversee development plans for those candidates, with the assistance of our Senior Vice President, Legal and Organizational Effectiveness and third-party consultants. In addition, the Compensation and Human Resources Committee identifies candidates who could step into the role immediately in the event the CEO departs unexpectedly or becomes temporarily incapacitated.

ESG OVERSIGHT

Hudbay believes that continuously improving how we manage the social, environmental and economic risks, impacts and opportunities associated with our activities is critical for our long-term success. Our focus on sustainability helps us meet stakeholder expectations, benefit from positive developments and manage challenging circumstances.

Social, environmental and economic sustainability are embedded into Hudbay's overall management approach, and governance of these matters starts at the Board level. The EHSS Committee has been delegated oversight authority over the Company's strategy, compliance and management systems related to health and safety, environmental matters, climate-related matters, reclamation and closure matters, community and stakeholder relationships (including social license and the engagement of Indigenous peoples) and human rights (including Indigenous rights) ("Sustainability Matters") and other committees have been delegated oversight of other ESG matters such as tailings, organizational culture, ED&I and corporate governance. Senior management has responsibility for the Company's overall sustainability governance processes while Business Unit and operations leaders are responsible for achieving and maintaining sustainable operations. Each operation has specialist personnel who are dedicated to the day-to-day management of health, safety, environmental, community relations and other social and human rights matters.

Climate-Related Governance and Risks

Our EHSS Committee is responsible for assisting the Board with its oversight of the design, implementation and effectiveness of the Company's strategy with respect to Sustainability Matters, including, without limitation, the adoption of any climate-related targets and any strategic plans to address other climate-related and nature-based risks and opportunities. In addition, the EHSS Committee is responsible for the monitoring of climate-related risks and other emerging nature-based risks and management is accountable for reporting these risks to the EHSS Committee through, among other processes, the ERM program. We have an EHSS Charter to make these accountabilities clear.

In addition, management has formed an ESG Steering Committee that reports to the EHSS Committee (as described below) and our Disclosure Committee is responsible for ensuring that the information we disclose with respect to Hudbay's environmental or climate-related strategy, targets or performance is adequately and properly substantiated, not misleading and reported in compliance with applicable laws and regulations.

Climate-Related Strategy and Targets

In 2021, we initiated a roadmap to identify and manage opportunities to reduce greenhouse gas ("GHG") emissions in alignment with global decarbonization goals. Since that time our business has diversified and grown substantially and we have dedicated efforts to developing a more sustainable plan to mitigate and track our GHG impacts.

In 2024, we established an ESG Steering Committee comprised of members of senior management and conducted a thorough analysis of our GHG reduction strategy and efforts. In early 2025, following this review, the ESG Steering Committee recommended a new approach to mitigate and track our GHG impacts that better reflects the diversified nature of our business and shared its findings with the EHSS Committee. This approach considers the differences between underground and open pit mining operations, and the unique demands of various business units in different locations.

Moving forward, we are committed to a GHG reduction strategy that requires each business unit to establish site-specific intensity targets that align with their operational context. We have gained buy-in from all business units to align with this strategy, allowing us to better track our performance and providing greater transparency for stakeholders.

In early 2026, Hudbay received a proposal from the Shareholder Association for Research and Education ("SHARE"), on behalf of Régime de retraite de l'Université de Montréal and the co-filer, the Hamilton Community Foundation (collectively, the "Proponents"), regarding the disclosure of an emissions reduction strategy for greenhouse gas emissions, including all material value chain emissions and longterm plans for direct emissions reduction.

As part of Hudbay's ongoing work on its emissions reduction strategy, Hudbay has developed a phased approach to understand and address Scope 3 emissions. Through discussions with the Proponents, Hudbay has agreed to pursue a measurable strategy to estimate material Scope 3 emissions. This work will initially include engaging suppliers and material customers to understand their emissions measurement and reduction efforts. Hudbay will articulate Phase One of its phased approach to addressing Scope 3 emissions and a commitment to setting a 2040 Scope 1 and Scope 2 target in its 2025 Annual Report.

As a result of these discussions and continued engagement with SHARE, the Proponents have agreed to withdraw the proposal.

Towards Sustainable Mining Program

As a member of the Mining Association of Canada, Hudbay participates in its TSM program, a leading sustainability standard in the mining industry. The TSM program is based on guiding principles and supported by a set of tools and performance indicators to ensure key mining risks are effectively managed. Participation in TSM supports accountability, transparency and credibility by evaluating and publicly reporting our performance across the following protocols and frameworks:

Indigenous and Community Relationships

Climate Change

Tailings Management

Biodiversity Conservation Management

Safe, Healthy and Respectful Workplaces

Crisis Management and Communications Planning

Water Stewardship

Preventing Child and Forced Labour

Mine Closure Framework

Equitable, Diverse and Inclusive Workplaces

The TSM protocols and frameworks are incorporated into our overall management systems and company standards. Although we are only required to implement the program at our Canadian operations, we commit to implementing the program at all of our operations globally. The goal is for each facility to achieve a minimum of Level A - which is considered good performance and demonstrates that commitments and accountabilities are in place and consistent with the protocol - in all performance areas.

Tailings Governance

Our Tailings Governance Charter specifies the governance that supports the safe, efficient and effective management of tailings facilities. Each site or business unit employs a tailings management system that supports the day-to-day activities - such as planning, monitoring, risk identification and reporting -associated with the safe management of tailings design, construction and operation.

One important requirement in the TSM protocol is that a company's governance defines and documents accountability and responsibility for tailings management. Our Accountable Executive Officer ("AEO"), who is our Chief Operating Officer, has the authority and responsibility to engage with Hudbay's Board on any issues related to tailings management. Each business unit Vice President has similar accountabilities to the AEO for facilities within their business unit. A Tailings Governance Team, composed of individuals from the business units and relevant corporate functions, serves in a monitoring and advisory role to assist the AEO in the design and implementation of appropriate processes to carry out the required third-party reviews and provide information to the AEO.

Our Senior Vice President, Exploration and Technical Services, is responsible for assisting our Chief Operating Officer and Technical Services team with the planning and oversight of tailings facilities in line with TSM requirements, Canadian Dam Association guidelines and applicable legislation. In addition, this individual is responsible for developing a strategy for the approval and execution of monitoring and reclamation activities for non-producing mines and facilities, which is an area of focus following the closure of our Flin Flon operations.

Key third-party roles include the following:

Annual tailings management reviews at our operating sites assess compliance with our Tailings Governance Charter and the TSM protocol. The review findings are reported to our Technical Committee, which oversees tailings management on behalf of the Board.

Sustainability Reporting

Hudbay has long believed that transparently disclosing our sustainability performance is good business and essential to earning and maintaining stakeholder trust. We have published an Annual Report (formerly referred to as our Sustainability Report) since 2004 and our 2025 report will be published in the second quarter of 2026 and be made available on our website at https://www.hudbay.com.
