TABLE OF CONTENTS

LETTER TO SHAREHOLDERS FROM THE CHAIR OF THE BOARD

Dear Shareholder,

2023 was a successful year for Hudbay. We delivered strong operating and financial results from our existing operations and positioned ourselves for long-term growth and stability through the acquisition of Copper Mountain and the completion of a pre-feasibility study for Copper World. Importantly, we achieved these successes while operating safely and sustainably in line with Hudbay's Purpose Statement, which was released in 2023 and is worth repeating:

"We care about our people, our communities and our planet. Hudbay provides the metals the world needs. We work sustainably, transform lives and create better futures for communities."

Operating Performance in Peru and Manitoba

In Peru, the year began under challenging circumstances. Following a change in the country's political leadership late in 2022, Peru experienced a period of social unrest which extended into the Cusco mining region, where Hudbay's Constancia mine is located. Our team in Peru was able to overcome these challenges with the benefit of strong community relationships. As a result, we were able to keep the Constancia mill in operation throughout this period and deliver full year production results that met (in the case of copper) or exceeded (in the case of gold) our annual production guidance, and cash costs that were within the annual cost guidance range.

Our strong operating performance in Peru benefited from the contribution of high-grade ore at the Pampacancha satellite deposit and the completion of a recovery improvement program at the mill, which drove higher production, reduced cash costs and enabled significant cash flow generation. In addition, we achieved a major milestone in our GHG reduction efforts by reaching a 10-year renewable energy supply agreement for Constancia in the first quarter of 2023, which will come into effect at the beginning of 2026. That, along with the permit application we submitted for the Maria Reyna property near Constancia, positions us well for a sustainable future in Peru.

Our Snow Lake operations in Manitoba had a similarly strong year. Through a continued focus on improvement initiatives aimed at supporting higher production and minimizing dilution at our Lalor mine, improving metal recoveries at the Stall mill and increasing throughput at the New Britannia mill, the team in Manitoba delivered on its annual production and cost guidance, and achieved record quarterly gold production in the fourth quarter. In addition, we expanded our prospective land package in the Snow Lake region by acquiring Rockcliff Metals Corp. and the Cook Lake properties near Lalor. These greenfield acquisitions, along with continued progress on the Flin Flon tailings reprocessing opportunity, position the Manitoba business unit well to extend the life of our operations and create sustainable long-term value for our stakeholders.

Copper Mountain Acquisition and Integration

The acquisition of Copper Mountain, a long-life, open-pit copper mine in British Columbia, was a significant addition to our portfolio of operating assets and was a major strategic milestone. It provides Hudbay with increased copper exposure and a more diversified and resilient operating platform that positions us well to deleverage our balance sheet and deliver on our strategic growth objectives. 

Since completing the acquisition of Copper Mountain in June 2023, Hudbay has been focused on integrating the business and advancing its plans to stabilize the mine over the next few years. The new technical report filed in December 2023, which is Hudbay's first technical report for Copper Mountain, reflects Hudbay's base case stabilization plan. The report identifies numerous opportunities to enhance the mine's production profile, reduce operating costs, and progress on process optimization.

Copper World Pre-Feasibility Study

In September 2023, we published a pre-feasibility study for Phase I of the Copper World project that significantly enhanced the economics and de-risked the project through higher levels of engineering, a simplified project design with an optimized site layout, lower upfront capital expenditures and a longer mine life. Phase I of the project now has a 20-year mine life requiring only state and local permits, with average annual copper production of approximately 92,000 tonnes over the first ten years.

While we continue to be very excited about the value that Copper World can deliver, we remain committed to taking a prudent approach to capital allocation and satisfying the conditions in our 3-P financing plan before making a sanctioning decision. We continued to make progress in this regard throughout 2023, as we advanced the State permits, deleveraged our balance sheet and began planning for a potential joint venture process.

Governance Updates

Upon completing the acquisition of Copper Mountain in June 2023, Jeane Hull and Paula Rogers were appointed to Hudbay's board. Ms. Hull and Ms. Rogers each served as directors of Copper Mountain prior to the acquisition and their respective skills, expertise and perspectives have helped complement the composition of our board. Their addition also increased the size of our board to twelve directors. On the recommendation of our Corporate Governance and Nominating Committee, we determined that it would be in the best interest of the company to reduce the size of the board at this year's annual meeting and each of Sarah B. Kavanagh and Daniel Muniz Quintanilla indicated they were willing to not stand for re-election.

I'd like to recognize Ms. Kavanagh and Mr. Muniz Quintanilla for their years of dedicated service and valuable contributions.

I am pleased to share that of our ten proposed director nominees, 40% are women and 60% identify as a member of a designated group, which once again achieves our targets set forth in our Diversity Policy.

* * *

In closing, I'd like to thank all our employees for their contributions to Hudbay's successes in 2023 and recognize the support of our shareholders. We look forward to continued engagement with our employees, shareholders and other stakeholders as we work towards achieving Hudbay's strategic objectives in line with our Purpose Statement.

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

Stephen A. Lang

Chair, Board of Directors

MANAGEMENT INFORMATION CIRCULAR

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 21, 2024 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://web.lumiconnect.com/253759077. 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", the "Company" and the "Corporation", 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 8, 2024 and all dollar references in this Circular are to Canadian dollars, unless otherwise stated.

GENERAL PROXY INFORMATION

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 21, 2024, 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 us.  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

On or around April 17, 2024, 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, 2023 and 2022 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 tsxtis@tmx.com.  In order to receive a paper copy in time to vote before the Meeting, requests should be received by May 9, 2024.

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

WHO CAN VOTE

The record date for the Meeting is April 2, 2024.  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.

VOTING YOUR COMMON SHARES AND PARTICIPATING AT THE MEETING

This year we are once again 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 participate at the Meeting.

Shareholders are strongly advised to carefully read the voting and participation instructions below that are applicable to them as well as the Virtual AGM User Guide attached as Schedule "C" to this Circular.

Registered Shareholders

If you were a registered shareholder on the record date, you may vote online at the virtual Meeting at https://web.lumiconnect.com/253759077. Click on 'I have a Control Number' and you will be prompted to enter your twelve-digit TSX Control Number and the password, which is: Hudbay2024 (case sensitive).  You must be connected to the internet at all times to be able to vote at the virtual meeting and it is your responsibility to make sure you stay connected for the entire Meeting.  Registered shareholders on the record date who voted prior to the Meeting do not need to vote again during the Meeting.

Alternatively, you may give another person authority to represent you and vote your shares online at the virtual Meeting, as described below under the heading ''Voting Your Common Shares by Proxy''.

If a registered shareholder would like to ask a question at the Meeting, login using your TSX Control Number and select the messaging icon. Messages can be submitted at any time during the Q&A session up until the Chair closes the session. 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

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 on the record date.  However, it 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, 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.

Please note that if you are a non-registered shareholder, regardless of whether you are a NOBO or an OBO, and you wish to vote online at the virtual Meeting, you will not be recognized at the Meeting for the purpose of voting Hudbay Shares registered in the name of an intermediary unless you appoint yourself as a proxyholder and register with our transfer agent, TSX Trust Company, by emailing tsxtrustproxyvoting@tmx.com the "Request for Control Number" form, which can be found at https://tsxtrust.com/resource/en/75 (see "Appointing a Proxyholder" below). 

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 16, 2024 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://web.lumiconnect.com/253759077.

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 21, 2024 should promptly contact LUMI directly, our virtual meeting provider, by visiting LUMI's support portal at https://support.lumiglobal.com/knowledge/virtual for common troubleshooting information or to use LUMI's virtual assistant to ask LUMI any related questions.

VOTING YOUR COMMON SHARES BY PROXY

Deadline for Proxies

Any proxy to be used at the Meeting must be received by Hudbay's transfer agent, TSX Trust Company, prior to 2:00 p.m. (Eastern Time) on May 16, 2024, or 48 hours (excluding Saturdays, Sundays and holidays) before any postponement or adjournment of the Meeting.  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 particular late proxy.

Registered shareholders may provide their voting instructions by any of the following means:

Non-registered shareholders may provide their voting instructions by mail, by telephone or online at www.proxyvote.com by following the instructions provided to them in their VIF.

Your Proxy Vote

On the form of proxy, you can indicate how you want to vote your Hudbay Shares, or you can let your proxyholder decide for you.

All Hudbay Shares represented by properly completed proxies received by Hudbay's transfer agent, TSX Trust Company, no later than 2:00 p.m. (Eastern Time) on May 16, 2024 or 48 hours (excluding Saturdays, Sundays and holidays) before any postponement or adjournment of the Meeting will be voted for, against or withheld from voting, in accordance with your instructions as specified in the proxy.  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 particular late proxy.

If you give directions on how to vote your Hudbay Shares on your form of proxy, your proxyholder must vote your Hudbay Shares according to your instructions.  If you have not specified how to vote on a particular matter on your form of proxy, your proxyholder can vote your Hudbay Shares as he or she sees fit.  If neither you nor your proxyholder gives specific instructions, your Hudbay Shares will be voted as follows:

• FOR the election of each of the ten director nominees;
• FOR the appointment of Deloitte LLP as our auditor for 2024 and the authorization of the Board, upon the recommendation of the Audit Committee, to fix the auditor's remuneration; and
• FOR the non-binding advisory resolution approving our approach to executive compensation.

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 management nominees 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 tsxtrustproxyvoting@tmx.com 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. 

Failure to register the proxyholder with our transfer agent will result in the proxyholder not receiving a Control Number to vote and participate at the Meeting.  Such an unregistered proxyholder will only be able to attend the Meeting as a guest.

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 16, 2024 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.  If you have already voted by proxy and you vote again during the online ballot during the Meeting, your online vote during the Meeting will revoke your previously submitted proxy.  If you have already voted by proxy and do not wish to revoke your previously submitted proxy, do not vote again during the online ballot vote.

Only registered shareholders have the right to revoke a proxy.  Non-registered shareholders who wish to change their vote must make appropriate arrangements with their respective dealers or other intermediaries.

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 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 April 2, 2024, the record date for the Meeting, 351,033,049 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, the persons 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 are as follows:

NOTICE TO UNITED STATES SHAREHOLDERS

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.

MATTERS TO BE ACTED UPON AT THE MEETING

1. FINANCIAL STATEMENTS

Our audited consolidated financial statements for the years ended December 31, 2023 and 2022 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. 

This year, the CGN Committee considered the composition and size of our Board in the context of the Copper Mountain acquisition, which resulted in two new directors being added to the Board in June 2023. Among other things, the CGN Committee considered the effectiveness (and costs) of a twelve person Board, the experience, skills and diversity of our directors and the benefits of Board renewal. The CGN Committee also considered the feedback it received from the directors and senior management as part of the annual Board evaluation survey and from shareholders as part of the Board's shareholder engagement process. Following its consideration of the foregoing issues and other relevant factors, the CGN Committee determined it would be in the best interest of Hudbay to reduce the size of the Board to ten directors, consistent with the size of the Board prior to completion of the Copper Mountain acquisition. On the recommendation of the CGN Committee, the Board Chair then had discussions with each of the individual directors to determine if any of them did not wish to stand for re-election at the Meeting. Following those discussions, the Board Chair confirmed that each of Sarah B. Kavanagh and Daniel Muniz Quintanilla were willing to not stand for re-election. The CGN Committee then considered the composition, experience, skills and diversity of the Board (among other factors) if Ms. Kavanagh and Mr. Muniz Quintanilla were no longer directors. The CGN Committee concluded that a ten person Board without Ms. Kavanagh and Mr. Muniz Quintanilla would continue to provide the skills, expertise and diversity of perspectives that the Board considers important to fulfill its oversight role in respect of Hudbay in an effective manner.

On the recommendation of the CGN Committee, the Board has determined to nominate each of the ten persons listed below for election as a director at the Meeting.  All of the nominees are current members of our Board (See "Nominees for Election as Directors" below). 

Hudbay wishes to thank Ms. Kavanagh and Mr. Muniz Quintanilla for their years of dedicated service and valuable contributions.

Ms. Kavanagh has served as a valued member of the Board since 2013 and, during her time as a director, she acted as Chair of the Audit Committee (from 2014 to 2019) and is currently Chair of the EHSS Committee. During the past decade, Ms. Kavanagh played an important role in Hudbay's growth into a responsible copper-focused mining company, with a world-class pipeline of copper growth projects. Most recently, in her role as EHSS Chair, Ms. Kavanagh helped the Board oversee the development of Hudbay's GHG reduction strategy and climate change initiatives.

Mr. Muniz Quintanilla joined the Board in 2019 and was an important part of the leadership transition that took place following Mr. Kukielski's appointment as CEO in 2020. During his time on the Board, Mr. Muniz Quintanilla made valuable contributions in a number of areas and served on the Audit, EHSS and Technical Committees.

The Board recommends that shareholders vote FOR the election of each of the ten nominees as directors.

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 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.  Our Advance Notice By-Law is intended to facilitate an orderly and efficient process for the election of directors.

Eight of the ten incumbent nominees were elected as a director of Hudbay at our annual and special meeting of shareholders held on May 10, 2023 (the "2023 meeting").  We received proxies representing 185,759,030 Hudbay Shares in connection with the 2023 meeting representing 70.89% of our outstanding common shares.

Based on these proxies, the eight incumbent nominees listed below received the following favourable votes cast by proxy:

Jeane L. Hull and Paula C. Rogers were each appointed as directors of Hudbay in June 2023 in connection with the Copper Mountain acquisition. 

Nominees for Election as Directors

Unless authority to do so with respect to one or more directors is withheld, the persons named in the form of proxy intend to vote FOR the election of each of the ten nominees whose names are set forth below:

We do not contemplate that any of the nominees will be unable to serve as a director, but if that should occur for any reason prior to the Meeting or any postponement or adjournment thereof, it is intended that discretionary authority shall be exercised by the persons named in the accompanying form of proxy to vote any proxy for the election of the remaining nominees and any other person or persons in place of any nominee or nominees unable to serve.

The following tables set forth biographical and other information on each proposed nominee.

Penalties or Sanctions

To the best of our knowledge, no nominee has been subject to (i) any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority or has entered into a settlement agreement with a securities regulatory authority, or (ii) any other penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable investor in deciding whether to vote for the nominee.

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, 2023, Deloitte was paid $3,285,283 for audit services, $134,286 for audit-related services and $110,000 for other services. Deloitte was not paid any fees for tax-related services in 2023. 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, 2023 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.caand EDGAR at www.sec.gov/edgar.shtml.

The Board recommends that shareholders vote FOR the appointment of Deloitte as Hudbay's auditor and the authorization of the Board, upon the recommendation of the Audit Committee, to fix the auditor's remuneration.

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.

The Board recommends that shareholders vote FOR the advisory resolution approving Hudbay's approach to executive compensation.

STATEMENT OF CORPORATE GOVERNANCE PRACTICES

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 that shareholder value is enhanced without compromising our commitment to environmental, social and governance ("ESG") principles and 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.

Our Corporate Governance and Nominating ("CGN") Committee 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 www.hudbay.com.  The following is a description of Hudbay's corporate governance practices as approved by the Board.

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 strategic, operational, reporting, ESG and compliance 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 us, 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.

Eleven of our twelve current directors are independent. 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 nine of the ten 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. Only two of our nominee directors 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 two of our nominee directors sit 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 nominee directors 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, working with the Chief Executive Officer to ensure that the Board is appropriately involved in approving and supervising Hudbay's strategy and recommending procedures to enhance the work of the Board.  The Board has also adopted a position description for the Chair of each of the Board Committees.  The full position descriptions of the Board Chair and the Chair of each Committee, including a complete list of their responsibilities, which have been approved by the Board, are available on our website at www.hudbay.com.

CEO Position Description

The Board has approved a position description for the Chief Executive Officer (available on our website at 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 reports formally to the Board, as well as less formally through discussions with members of the Board, to advise the Board on a timely basis of management's current and proposed courses of action.  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. 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, 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 the formal Board evaluation process that is carried out annually by the CGN Committee, as described under "Board and Committee Evaluations" below. In addition, in the current year, this was also considered in the context of the Copper Mountain acquisition, which resulted in the addition of two new directors to our Board in June 2023.

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 following Board skills matrix sets out the skills and expertise that the Board considers important to fulfill its oversight role in respect of Hudbay, the specific skills and expertise of each director nominee and the current strengths of the Board as a whole.  Each director is required to complete a self-assessment of his or her skills and such data is compiled into the matrix.  The Board skills matrix is maintained to identify and evaluate the competencies and skills of its members based on the individual experience and background of each director and to identify areas for strengthening the Board, if any, and address them through the recruitment of new members.

1. ⬤ Indicates a high degree of experience or expertise in the subject area.

2. O Indicates some or limited experience in the subject area.

Board and Committee Evaluations

Annually, under the supervision of the CGN Committee, the directors conduct a formal evaluation of the performance and effectiveness of the Board and its Committees.  As part of this process, each director and members of senior management are interviewed by a member of the CGN Committee to assess the performance of the Board, its Committees and the individual directors, the independence of the Board, its relationship with senior management, the performance of the Chair, the Board's role in shaping the company's strategic priorities and culture and any other issues of concern.  The results of these interviews were reviewed by the CGN Committee at its meeting on January 17, 2024, then reported to the Board by the Chair of the CGN Committee.  A formal written report is circulated to the directors and members of senior management, and the Chair of the CGN Committee, the Board Chair and the President and CEO work to ensure the recommendations contained in the report are implemented.

Members of each Committee are also 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.

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 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 and the Board will ask directors who are no longer able to contribute effectively to step down from the Board.

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 director attendance at Board and committee meetings held during the year ended December 31, 2023.

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, 2023, the Board held in camera sessions of the independent directors at all 12 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 Code of Business Conduct and Ethics, Corporate Governance Guidelines and Board Charter, Committee charters and other key policies, descriptions of our organizational structure, operational reports, 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 2023:

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. 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 held a meeting in August 2023 that focused solely on strategy.

RISK MANAGEMENT

A key element of the Board's responsibilities is to review the principal strategic, operational, ESG, reporting and compliance 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:

Among its responsibilities, Hudbay management is responsible for:

• 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 Executive Director, Internal Audit and Compliance 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.

EQUITY, DIVERSITY AND INCLUSION

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, 40% 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 and 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.

The CEO is tasked with ensuring the objectives of our Diversity Policy are applied with respect to senior management positions. 

Although we do not have specific targets regarding directors and executive officers for each of the designated groups, we have a target of at least 30% women directors and believe that our Diversity Policy and Corporate Governance Guidelines, together with our other equity, diversity and inclusion initiatives described below, encourage our CGN Committee and management to consider the current number of women and members of other designated groups when selecting director candidates and members of senior management.

Equity, Diversity and Inclusion (ED&I) Initiatives

In 2020, Hudbay management formed an Equity, Diversity and Inclusion Committee (the "ED&I Committee").  The ED&I Committee consists of a group of employees at the corporate office that expressed a desire to foster and advance Hudbay's commitment to ED&I throughout the organization.  Since that time, the ED&I Committee has developed a Diversity and Inclusion Policy ("ED&I Policy"), 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 Indigenous awareness training, ED&I training, 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 and measuring our progress toward achieving our ED&I objectives.

Our Peru Business Unit established its own ED&I committee and has successfully launched an ED&I program called "Nuestras Voces" (Our Voices). The acronym VOICES represents the following focus areas for fostering a workplace where everyone feels welcome and thrives:

• Values - Our values in action foster a DE&I work environment

• Openness - We promote being a role model in inclusive leadership

• Inclusion - All communities and interest groups are valued

• Confident - Develop a psychologically safe environment

• Education - Promote, develop and generate opportunities through education

• Sustainable - Empower schools in the Chumbivilcas province through access to quality learning

The "Nuestras Voces" program 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 already has two classes of Hatun Warmi who completed the program, with a total of 23 women who have graduated. To date, 15 of those women have joined Hudbay's permanent workforce in Peru.  Another successful initiative was the community co-op concentrate transport program, which has resulted in approximately 35% of our concentrate production from Constancia now being transported by the local communities.

To promote gender diversity in the Manitoba Business Unit, the Hudbay Women's Network ("HBWN"), was founded in 2018 by two female employees in our Manitoba Business Unit.  The HBWN's founding principle is gender inclusion, and its goal is to support, connect and empower Hudbay employees by providing a vehicle for professional growth and a strong voice.  The HBWN is supported by our female directors, who have met with the HBWN to share their experiences and provide mentoring, and work is underway to expand the HBWN across the organization.

The Manitoba Business Unit has also launched the Indigenous Circle for Everyone program, which provides an opportunity for employees across the organization to listen and learn from Indigenous elders and other Indigenous knowledge holders from our local communities in Manitoba.

Measuring our Success

Hudbay intends to measure the effectiveness of its ED&I Policy and our other ED&I initiatives by monitoring the increase in female representation and representation of other designated groups 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.

Over the past two years, we have enhanced the diversity of our Board through the addition of three new directors who identify as either women or a member of an Indigenous group.

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.

In furtherance of this goal, in 2022, we created a two-year development program for those 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. Currently, approximately one third of our participants in the development program are women, while another development program is exclusively focused on building female leaders. In 2023, two women from Hudbay (one from the corporate office and one from the Manitoba Business Unit) participated in an external networking and leadership development program for women in mining. The year-long program combined three face-to-face meetings held in Canada with several virtual sessions for women who work in historically male-dominated industries to connect, share experiences and further develop their leadership skills.

The number and percentage of our ten nominee directors who identify as a woman or as a member of another designated group is as follows:

(1) One nominee director identified as a woman, an Indigenous person and a visible minority, indicating that six of ten nominee directors identify as a woman or as a member of another designated group.

The number and percentage of our fifteen officers who are women or identify as a member of another designated group is as follows:

SUCCESSION PLANNING FOR EXECUTIVE OFFICERS

Hudbay has a formal process for succession planning for its executive officers.  The Chief Executive Officer is responsible for overseeing the succession planning process for all executive roles and critical skills roles below the CEO level.  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, following which a formal succession plan is prepared and reported to the Compensation and Human Resources Committee and Board.

The Compensation and Human Resources Committee is responsible for overseeing a succession plan for the CEO and reporting on its succession planning to the full Board.  Among other things, the Compensation and Human Resources Committee and Board consider internal candidates with long-term potential to serve as Hudbay's CEO and oversee development plans for those candidates. They also identify 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 licence 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 targets to reduce greenhouse gas emissions 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. To make these accountabilities clear, our EHSS Committee Charter was updated in 2023.

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. We regularly reported on this roadmap to the EHSS Committee and, in December 2022, we announced our commitment to achieve net zero GHG emissions by 2050 and the adoption of interim 2030 GHG reduction targets to support this commitment. Our GHG reduction targets were developed following a thorough review of our existing emissions and evaluation of reduction opportunities that are achievable without compromising the long-term economics of our operations and projects.

While our operations are well-positioned in the lower half of the global GHG emissions curve for copper operations, we recognize our role in mitigating climate change. Hudbay's GHG emissions reduction plan includes the following initiatives:

• Pursuing a 50% reduction in absolute Scope 1 and Scope 2 emissions from existing operations by 2030 (compared to 2021)
• Achieving net zero total emissions by 2050
• Reporting on material Scope 3 emissions in the near-term
• Assessing acquisitions and new projects against corporate emissions targets
• Continuing to be transparent with GHG performance data disclosure, including reporting total GHG emissions and GHG intensity
• Evaluating new technologies as they become commercially available and economically viable

In 2023, the company made significant progress towards its climate change goals, including:

• Peru Renewable Power Supply Agreement - During the first quarter of 2023, Hudbay signed a new 10-year power purchase agreement with ENGIE Energía Perú for access to a 100% renewable energy supply to Constancia. The agreement will come into effect in January 2026 following the conclusion of Constancia's existing power supply agreement. Total Scope 1 and Scope 2 GHG emissions at Hudbay's current operations (other than Copper Mountain) are expected to decline by 40% during the life of the contract (as compared to our 2021 baseline), positioning Hudbay well to achieve its 50% reduction target by 2030.
• Electric Shovel at Copper Mountain - In September 2023, Hudbay commissioned a new Komatsu PC8000 electric shovel at the Copper Mountain mine, which reduces carbon intensity by displacing existing diesel shovel production.
• Renewable Diesel at Copper Mountain - Hudbay tested the use of renewable diesel in two of its non-trolley assist haul trucks at Copper Mountain in an effort to further reduce GHG emissions. The test results were promising and the company subsequently entered into renewable diesel contracts for approximately 80% of the expected fuel to be purchased in 2024.
• Electric Scooptram at Lalor - In the first quarter of 2023, Hudbay initiated the trial of an electric Epiroc scooptram ST14 SG at the Lalor mine, which reduces carbon intensity by lowering emissions and reduces the temperature in the lower areas of the mine to improve ventilation. The trial was successful and, in the third quarter, a second electric scooptram was added to the fleet.

Hudbay has been reporting global GHG emissions data and performance to the CDP Climate questionnaire for more than 10 years. The company's 2022 Annual Sustainability Report maps our CDP responses to the Task Force on Climate-related Financial Disclosures recommendations. Hudbay also aligns with the TSM environmental protocols, including the updated TSM Climate Change Protocol.

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
• Safety and Health
• 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.

To support our tailings management initiatives, in early 2023, we created a new role and appointed a Vice President, Business Planning and Reclamation. This member of our management team 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:

• Independent technical review board ("ITRB") - a panel of qualified and experienced individuals, who have not been directly involved with the design or operation of the facility, evaluates the technical aspects of TSFs at least annually (and typically twice per year - one being a site visit and the other a teleconference) throughout the mine lifecycle.  The ITRB's findings are reported by management to the Board's Technical Committee and the Technical Committee Chair may elect to meet with management and the ITRB as needed.

• Engineer of record ("EOR") - a qualified individual who verifies that the facilities are designed, constructed and performing in accordance with performance objectives and all applicable guidelines, standards and regulatory requirements.

• Dam safety review provider - an external expert conducts dam safety reviews, independent of the ITRB and EOR, every five years, as per the recommendation of the Canadian Dam Association's Dam Safety Guidelines.

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.

In addition, in 2023 our Technical Committee and certain other directors attended a site visit to our Manitoba operations and received a tour of our tailings management facilities in Snow Lake.

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 Sustainability Report since 2004.  Our 2023 Annual Sustainability Report will be published in the second quarter of 2024 and our 2022 report is available on our website at www.hudbay.com.

For several years, Hudbay has published its ESG disclosures in accordance with the GRI (Global Reporting Initiative) guidelines and standards.  We have also participated in CDP's annual questionnaires on our greenhouse gas emissions, water management practices and forest-related risks and opportunities.

For many years, the GRI and CDP have been considered two of the most credible and widely adopted sustainability/ESG reporting frameworks. However, two other frameworks emerged that reflect how reporting is evolving to include issues of interest to investors and other stakeholders. The Sustainability Accounting Standards Board ("SASB") created a standardized methodology for reporting sustainability information that is material to investors and for allowing stakeholders to compare peer performance within an industry.  The Task Force on Climate-related Financial Disclosures ("TCFD") framework seeks to provide stakeholders in the financial markets (e.g., investors, lenders, insurers and regulators) climate-related information useful to decision making. As investor interest in ESG matters increases, SASB and TCFD are emerging as equally credible standards and frameworks to GRI. 

Our 2023 Annual Sustainability Report is prepared pursuant to the GRI guidelines, the SASB Metals and Mining Standard and the recommendations of the TCFD.

Because the multiple frameworks may have an unintended result of creating complexity and becoming onerous, there are several efforts underway to converge the various sustainability reporting standards into a single reporting framework. We are monitoring these developments, as well as the proposal from securities regulators to disclose climate-related information in our continuous disclosure filings, as we continuously improve our reporting disclosures and transparency on our performance.

ETHICAL BUSINESS CONDUCT

As part of its commitment to maintaining the highest ethical standards, the Board has adopted a Code of Business Conduct and Ethics (the "Code").  The Code applies to all of our directors, officers and employees, our subsidiaries and affiliates and other persons in similar relationships with those entities. The Code addresses such matters as compliance with laws, conflicts of interest, confidential information, protection and proper use of Hudbay assets, fair dealing, rules and regulations and the reporting of illegal and unethical behaviour, including laws prohibiting improper payments to government officials.

In addition, we have adopted a Certification Policy, in accordance with which new employees must read the Code when hired or appointed and acknowledge that they will abide by the Code.  The Certification Policy also requires that all directors, officers and employees with an active Hudbay email address across the organization annually certify their understanding of the Code and acknowledge that they will abide by the Code.  We regularly conduct training sessions across the organization relating to applicable laws prohibiting bribery, to ensure that employees, especially those who may interact with government and other third parties, understand such laws and know how to comply with them.  In early 2024, we completed an online certification campaign in which all employees with an active Hudbay email address were provided copies of the Code and our key compliance policies (including anti-corruption policies) and asked to e-sign the policies to certify their understanding of the policies and their compliance therewith.  In addition, in the third quarter of 2023, we completed an online certification campaign for the Copper Mountain employees who joined the Hudbay organization as part of our onboarding process. Also during 2023, targeted compliance training was carried out by our Peruvian business unit's compliance function, which training included specialized training for the Procurement and Finance teams and an in-person anti-corruption workshop for our Institutional Relations and Government Relations leaders.

As part of our ongoing commitment to ethical business conduct, in 2022 we completed a comprehensive review of our anti-bribery and corruption policies, which resulted in updates to our Code of Business Conduct and other related compliance policies. We also engaged a third-party expert to carry out an anti-corruption risk assessment and review of Hudbay Peru's compliance program, which was completed in 2023. The review found that Hudbay Peru has a comprehensive and mature compliance program that is appropriately designed for the potential risks the company faces. We followed this with an Internal Audit of our vendor onboarding procedures in Peru. We utilized the findings of the internal audit and the potential enhancement opportunities that were identified by the third-party review to update our Global Supplier Due Diligence Policy in early 2024.

The Board has also adopted a Statement on Anti-Corruption to further demonstrate our commitment to conducting business honestly, ethically and in compliance with the laws of the jurisdictions in which we operate and have assets.  In addition, our Global Supplier Due Diligence Policy and our supplier and customer codes of conduct are intended to ensure that we and our subsidiaries transact with suppliers and customers who share our expectations for ethical conduct and compliance with laws.

We encourage personnel who become aware of a conflict or potential conflict or departure from the Code to bring it to the attention of a supervisor or department head.  The Board has adopted a Whistleblower Policy for employees and others to report concerns regarding, among other things, violations of the Code or anti-bribery legislation or concerns regarding financial statement disclosure issues, accounting, internal accounting controls or auditing matters.  These concerns may be reported to the Chair of the Audit Committee, who will promptly conduct or assign an individual, who may be a member of senior management or another person, to conduct a thorough investigation of the complaint.  In addition, under the Whistleblower Policy, Hudbay has a third-party hotline and website that allows individuals to report any concerns about inappropriate business conduct confidentially and anonymously.  These concerns can be reported online, by mail or by phone.

The Board, through the Audit Committee, monitors compliance with the Code.  Hudbay's Senior Vice President, Legal and Organizational Effectiveness provides day-to-day management over Hudbay's global compliance with the Code and other core policies, including management of our Whistleblower Policy and program, and reporting quarterly on such matters to the Audit Committee.

Any waivers of the Code for directors or members of senior management may only be granted by the Board.  The Board did not grant any waiver of the Code in 2023.  In the unlikely event of such a waiver, it will be disclosed to shareholders as required by applicable law.

A copy of the Code may be accessed on our website at www.hudbay.com or on Hudbay's profile on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar.  Copies of the Whistleblower Policy, Supplier Code of Conduct and Ethics, Customer Code of Conduct and Ethics and our Statement on Anti-Corruption may also be accessed on our website at www.hudbay.com.

Additionally, in compliance with the Fighting Against Forced Labour and Child Labour in Supply Chains Act (referred to as Canada's "Modern Slavery Act"), Hudbay will be publicly filing its initial 2023 Modern Slavery Report for the reporting period ending December 31, 2023 (the "2023 Modern Slavery Report"). A copy of the 2023 Modern Slavery Report will be made available to shareholders on our website at www.hudbayminerals.com/disclosure-centre.

SHAREHOLDER ENGAGEMENT

We communicate with our shareholders in a wide variety of ways, including through our website, news releases and other public disclosure documents, investor presentations, industry conferences and meetings with our shareholders.  We also hold conference calls in respect of quarterly earnings releases and major corporate developments and such calls are open to be heard by the public.  Details of the notice of time, place, general substance and method of accessing any such call and instructions as to where the public will be able to access archived audio webcasts of the call are broadly disseminated.

The Board of Directors is committed to engaging in constructive communications with our shareholders and the Board maintains a Shareholder Engagement Policy, which is available on our website at www.hudbay.com. In addition to our annual general meeting, during which shareholders have the opportunity to interact with our directors, the policy expresses our directors' interest in meeting with key shareholders to discuss specific matters of mutual interest and concern. As part of these efforts, in 2023, our Board Chair reached out to our 30 largest shareholders and offered to meet with such shareholders without management present to discuss governance topics of interest. This resulted in meetings between our Board Chair and certain other committee chairs with some of our significant shareholders.

Shareholders may also initiate communication directly with the Board by contacting our Chair by mail or email at:

Hudbay Minerals Inc.
Attention: Chair of the Board
25 York Street, Suite 800
Toronto, Ontario, Canada M5J 2V5
Email: Chair@hudbay.com

Our Chair and other members of our Board and management team continue to be in frequent contact with many of our shareholders and remain committed to constructive engagement with all shareholders.

DISCLOSURE POLICY

In addition to our timely and continuous disclosure obligations under applicable law, we also have a formal policy for dealing with analysts, shareholders and the media.  Our Disclosure Policy is intended to ensure that we provide timely disclosure of material information in a manner that is broadly accessible on a non-exclusionary basis by all market participants.

Hudbay's management has established a Disclosure Committee that is responsible for ensuring that information is disclosed in accordance with the Disclosure Policy and otherwise in accordance with applicable securities laws.  The members of the Disclosure Committee generally include the President and Chief Executive Officer, the Chief Financial Officer, the Chief Operating Officer, the Senior Vice President, Legal and Organizational Effectiveness, the Vice President, Investor Relations and such other members of senior management deemed appropriate from time to time by the Disclosure Committee.

The Disclosure Committee reviews and supervises the preparation of all news releases and public filings prior to their release, oversees the disclosure of information on our website and assists Hudbay management with their evaluation of the effectiveness of our disclosure controls.  In addition, the Board gives final approval of material disclosure items and all news releases and public filings disclosing Hudbay's financial performance are reviewed by the Audit Committee, which ultimately recommends such disclosure for approval by the Board.

COMMITTEES OF THE BOARD

The Board has established five standing Committees to assist it in discharging its mandate.  The roles of the five standing Committees are outlined below and their charters may be viewed on our website at www.hudbay.com.

Independence of Committees

The members of the Board's Committees are appointed by the Board upon the recommendation of the CGN Committee.  All of our directors who are currently members of Committees of the Board are independent directors within the meaning of applicable securities laws and the categorical standards set out in our Corporate Governance Guidelines.

Audit Committee

Members: Carol T. Banducci (Chair), Daniel Muñiz Quintanilla, Paula C. Rogers and David S. Smith.

The duties of the Audit Committee include making recommendations to the Board with respect to our quarterly and annual financial results, including management's discussion and analysis thereof, and reporting to the Board any issues of which the Audit Committee is aware respecting the quality or integrity of our financial statements, any significant financial reporting issues and judgments made in connection with the preparation of our financial statements and the adequacy of our internal controls.  The Audit Committee also oversees the performance of our independent auditor and the scope of its audit, as well as our internal audit function and our ERM, information technology, cyber security and insurance programs.  The Audit Committee receives regular reports from management on internal audit, risk management, information technology, cyber security, tax strategy, insurance, litigation, compliance with the Code, pension plans and other matters.  In addition, the Audit Committee is responsible for overseeing investigations into any complaints received by our third-party whistleblower service and for ensuring that appropriate resources are allocated to such investigations.

The Audit Committee meets at least quarterly and meets separately with senior management, the independent auditor and internal audit group as appropriate.  All regular meetings of the Audit Committee include a session at which only members of the Audit Committee are present, a session at which the head of internal audit is present with the Audit Committee without other members of management and a session at which only representatives of the independent auditor are present with the Audit Committee.

None of the members of the Audit Committee may serve on the audit committee of more than three reporting issuers in addition to Hudbay without the prior approval of the Audit Committee, the CGN Committee and the Board. No member of the Audit Committee serves on the audit committee of more than two other reporting issuers.

Information about the background and experience of each Audit Committee member and the remuneration of the independent auditor for the last two years is contained in Hudbay's Annual Information Form ("AIF") for the year ended December 31, 2023 under the heading "Audit Committee Disclosure" and a copy of the Audit Committee's charter is attached as Schedule "C" to the AIF.  Our AIF may be found on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar.

Compensation and Human Resources Committee

Members: Carin S. Knickel (Chair), Carol T. Banducci, Stephen A. Lang and Colin Osborne.

The Compensation and Human Resources Committee assists the Board in discharging its responsibilities relating to recruitment, development and retention of senior management, performance evaluations and compensation of senior management, senior management and critical skills succession planning, compensation structure for the Board and senior management, including salaries, annual and long-term incentive plans and share ownership guidelines. 

In 2023, the Committee's activities included providing oversight of management's integration plan for the Copper Mountain acquisition, reviewing the Company's high potential employee leadership program and ED&I initiatives, reviewing management's collective bargaining agreement negotiation strategy and reviewing the Company's succession planning strategy for executive officers (including the CEO) and critical skills employees.

For a detailed discussion of the role of the Compensation and Human Resources Committee and its activities in 2023, including its oversight of executive compensation and its review of Hudbay's 2023 performance against the corporate scorecard, see "Statement of Executive Compensation".

Corporate Governance and Nominating Committee

STATEMENT OF EXECUTIVE COMPENSATION

MESSAGE FROM THE CHAIR OF THE COMPENSATION AND HUMAN RESOURCES COMMITTEE

Fellow Shareholders,

A Year of Successes

2023 saw successes across all elements of Hudbay's business. In its operations, the company met or exceeded its production guidance and achieved its cost guidance. The year began with our Peru team navigating road blockades that impacted the entire country and caused logistical and supply chain problems that impacted our operating results early in the year. The team was able to overcome these challenges with the benefit of our strong community relationships. By the end of the year, our Peru operations were contributing to new Hudbay records in annual revenue and gold production, driven by contributions from the high grade Pampacancha deposit and record copper recoveries at our Constancia mill. Also in 2023, we accomplished a major milestone toward achieving our 2030 greenhouse gas reduction targets when our Peruvian subsidiary entered into a 10-year renewable power supply agreement for Constancia.

Our Manitoba team was equally successful in 2023. In our first full year of operating only in Snow Lake following the planned closure of our 777 mine, the team advanced many efficiency improvements to support higher production at Lalor, including reducing mining dilution and enhancing hoisting capacity. These initiatives, along with the completion of recovery improvement projects and record throughput at our New Britannia mill resulted in record fourth quarter gold production with very strong cost performance. With a development drift to the nearby 1901 deposit underway, the initiation of our largest-ever exploration program in Manitoba, and an exciting opportunity to reprocess tailings at our tailings dams in Flin Flon, our Manitoba team is well positioned to profitably perpetuate the business for many years to come.

In Arizona, we released an enhanced and de-risked prefeasibility study for Phase I of our Copper World project. We've received the first of three key state permits required to develop Copper World and we expect the other two to be approved later in 2024. We remain excited about the opportunities presented by the project and we believe Copper World is one of the best undeveloped copper projects in the Americas.

Along with these achievements at our business units, Hudbay advanced initiatives designed to strengthen the company's culture and the engagement of its people. The company launched the first year of its high-potential employee leadership development program and completed a new supervisory leadership development program in Manitoba, with plans to roll the program out at its other operations starting in 2024. Hudbay also launched a new purpose statement in 2023, outlining the company's commitment to its employees, members of nearby communities, and other key stakeholders. Following engagement across our business, the company's Diversity, Equity and Inclusion Committee presented its strategy and action plan to the Committee.

On top of these successes, we acquired the Copper Mountain mine in mid-2023. Copper Mountain provides our business with additional scale, geographic diversification and copper exposure. It also gives us the opportunity to unlock value through operating efficiencies and future cash flows to accelerate our deleveraging efforts. Since its acquisition, the team at Copper Mountain has been focused on advancing stabilization plans and achieving the mine plan set forth in the new NI 43-101 technical report that was published in late 2023.

Executive Compensation in 2023

As it does each year, Hudbay's Compensation and Human Resources Committee works with management to develop strategic and operational objectives for the year. These objectives are included in the corporate scorecard that is used in determining short-term incentive (STIP) awards for our executives and other employees. The corporate scorecard we approved in early 2023 focused on production and costs, cash flow generation, safety, ESG initiatives and advancing operational improvements in Manitoba and Peru.

After acquiring Copper Mountain mid-way through 2023, the Committee considered how to reflect its contribution to our executives' STIP awards for the year. The Committee determined it was not advisable to create a new corporate scorecard in the middle of the year which included metrics for Copper Mountain. Instead, the Committee decided to assess management's performance against the original corporate scorecard that was adopted at the start of the year, then use its discretion to adjust the score based on Copper Mountain's contribution. After considering Copper Mountain's operational performance, integration efforts, and the technical and strategic merits of the transaction, the Committee assigned an overall corporate score for 2023 of 122/100, which the Committee believes reflects management's strong performance across all aspects of its business, along with the contribution of Copper Mountain.

The pages that follow provide you with our report on the company's executive compensation, along with a description of how our executives' compensation outcomes are consistent with the company's performance. In 2024, management will continue to focus on operational performance, including meeting production and cost targets without compromising our commitment to safety, strengthening our balance sheet through deleveraging and cash flow generation, and continuing to pursue our strategic goals. The Committee will ensure that management is appropriately incented to achieve these objectives through an executive compensation program that rewards performance while continuing to support the winning culture we have worked to achieve. The Committee would be happy to discuss these matters further with our shareholders and we will be available at our annual shareholders' meeting to answer any of your questions.

Sincerely,

Carin S. Knickel

Committee Mandate

The Committee assists the Board in discharging its responsibilities relating to recruitment, development and retention of senior management, officer appointments, performance evaluations of senior management, succession planning, compensation structure for the Board and senior management, including salaries, annual and long-term incentive plans and share ownership guidelines.

The responsibilities of the Committee, as set forth in its Charter, are available on our website at www.hudbay.com.

COMMITMENT TO TRANSPARENCY, GOOD GOVERNANCE AND RISK MITIGATION

The Committee and the Board are committed to good governance, transparent disclosure and a productive dialogue with our shareholders about our executive compensation program. The Committee considers the risks associated with our compensation policies and practices and is comfortable that they are not likely to have a material adverse effect on Hudbay. The following list highlights key policies and practices that have been adopted by Hudbay, which we believe are in the best interest of shareholders and align with corporate governance best practices:

EXECUTIVE COMPENSATION OVERVIEW

Named Executive Officers

For 2023, our Named Executive Officers, referred to as our NEOs, were:

• Peter Kukielski, President and Chief Executive Officer (CEO);
• Andre Lauzon, Chief Operating Officer;
• Eugene Lei, Chief Financial Officer;
• Patrick Donnelly, Senior Vice President, Legal and Organizational Effectiveness; and
• Javier Del Rio, Senior Vice President, South America and USA.

Compensation Philosophy

Our executive compensation philosophy is to:

• provide competitive compensation to attract and retain a talented and high-achieving executive team;
• appropriately incent our executives to achieve our strategic and operational objectives; and
• align the interests of our executives with the long-term interests of our shareholders.

Accordingly, and as outlined throughout this Compensation Discussion and Analysis, our compensation program is structured with the following elements in mind:

• a significant portion of total compensation is variable and "at risk" and linked to corporate and individual achievements tied to our strategic plan;
• our compensation program, along with our equity ownership guidelines and employee share purchase plan, fosters share ownership among our executive team; and
• we generally target our executive's compensation at the market median.

Compensation Comparator Group

The compensation comparator group shown below was approved by the Committee in 2022, for the purpose of determining where our executives were compensated in relation to their peers to facilitate decisions for 2023 target pay levels. The criteria used to develop the compensation comparator group are as follows:

(1) Public information from all applicable Compensation Comparator Group entities is provided as at December 31, 2023, except for OZ Minerals Limited and Yamana Gold Inc., whose information is provided as at December 31, 2022 as neither entity was a reporting issuer as at December 31, 2023.

Compensation Governance

Committee Activities

Since July 2022, the Committee has undertaken the following activities related to the 2023 and 2024 compensation process:

Roles of Management and Independent Advisor

The Committee works closely with our management team and the Committee's independent advisor in overseeing the activities outlined below.

The table below outlines the fees paid to Hugessen over the last two years for executive compensation related services. Hugessen did not provide any other services in either year. The additional fees incurred by Hugessen in 2023 related primarily to their comprehensive analysis of our short- and long-term incentive programs, review of director compensation and support with compensation determinations related to Copper Mountain.

Compensation Risk Management 

Commitment to Transparency, Good Governance, and Risk Mitigation

The Committee and the Board are committed to good governance, transparent disclosure and a productive dialogue with our shareholders regarding our executive compensation program. The Committee considers the risks associated with our compensation policies and practices and is comfortable that they are not likely to have a material adverse effect on Hudbay.

Our Audit Committee has been tasked by the Board with overseeing our Enterprise Risk Management program. As part of this program, key risks that could impact us are identified and assessed, and mitigation plans are put in place. Succession planning, recruitment and retention have been identified as key risks and the Compensation and Human Resources Committee receives quarterly updates on the risk drivers and mitigation plans in respect of these risks.

Clawback Policy

The Board has adopted an incentive-based compensation clawback policy (a "clawback policy"), which was amended in early 2023 to ensure compliance with recent SEC rule changes. The clawback policy is summarized below.

Equity Ownership Guidelines

To align executive and shareholder interests, the Board has established a policy that requires executives to own a minimum number of Hudbay shares and share units, as follows:

Equity ownership guidelines also apply to our directors, as described under "Director Compensation" below. Our current NEOs' progress in meeting our share ownership guidelines as at March 15, 2024 is shown in the following table:

1. Includes the grant date value of share units held and the acquisition value of Hudbay Shares held. In the case of Mr. Kukielski, the total under "Share Units" includes DSUs that he was awarded prior to his appointment as permanent CEO in early 2020.

COMPONENTS OF HUDBAY'S EXECUTIVE COMPENSATION PROGRAM

Summary of Elements of Executive Compensation

The following table provides a summary of the key elements of our executive compensation program, which we believe form an appropriate mix of compensation:

In 2023, approximately 80% of our CEO's and an average of approximately 73% of our non-CEO NEOs' target total direct compensation was variable and at-risk.

Base Salary

The Committee believes that our executives' base salaries must be sufficiently competitive to enable recruitment and encourage retention. However, reflecting our emphasis on variable and at-risk compensation, our executives' base salaries remain a relatively low portion of their overall total direct compensation. The Committee generally targets our NEOs' base salaries at the median of the comparator group.

The 2023 and 2024 base salaries of our NEOs are shown below.

1. Mr. Del Rio's base salary is paid in US dollars. For purposes of the table above, Mr. Del Rio's salary has been converted into Canadian dollars at an exchange rate of US$1.300 per $1.00. For clarity, Mr. Del Rio earned a base salary of US$413,400 in 2023 and is scheduled to earn a base salary of US$429,936 in 2024.

Short-Term Incentive Plan (STIP)

The STIP is an annual cash bonus based on a combination of corporate and individual performance throughout the year. Target STIP awards are denominated as a percentage of base salary and actual awards can range from 0% of target for performance outcomes that fall significantly below expectations to 200% of target for superior performance.

Corporate performance in a given year is measured using our Corporate Scorecard, as described in more detail below. Our CEO's annual STIP award is based 80% on corporate performance and 20% on individual performance and our non-CEO NEOs' STIP is based 70% on corporate performance and 30% on individual performance. Individual performance is assessed each year by the Committee, in consultation with the CEO. A summary of our NEOs' individual performance assessments can be found in "Determination of 2023 Individual Performance Scores".

2023 Corporate Scorecard

At the start of each year, the Board, upon the recommendation of the Committee, adopts the Corporate Scorecard, which sets forth key performance objectives that guide and motivate our executives as they carry out Hudbay's strategy over the course of the year. Management is expected to be rigorous in their goal-setting as the Committee is very reluctant to make adjustments to any performance objectives during the year. Performance is monitored throughout the year, and at year-end, the Committee assesses the Company's performance against each scorecard objective and considers all relevant factors, both positive and negative. While the Committee retains discretion to ensure that scorecard results are fair, they use this discretion cautiously and, where practical, use scorecard metrics that are objectively measurable so the use of discretion can be minimized.

As in prior years, the corporate scorecard the Board adopted in early 2023 included performance categories based on operational, ESG, financial and growth/strategic performance. After acquiring Copper Mountain in mid-2023, the Committee considered how to incorporate its performance into the scorecard. Rather than create a new scorecard which included metrics for Copper Mountain's performance, the Committee decided to assess management's performance using the original corporate scorecard that was adopted at the start of 2023. However, the Committee agreed that it would recommend to the Board that it use discretion to assess how Copper Mountain's impact on performance in the second half of the year would be incorporated into the final score used for determining STIP awards.

The results of management's performance against the 2023 scorecard metrics are shown in the table below. In addition, the Committee and the Board assessed Copper Mountain's operational performance, integration efforts and the technical and strategic merits of the transaction. Upon doing so, the Board assigned a final corporate score of 122/100, which reflected management's strong performance in the year along with the contribution of Copper Mountain.

1. Cost Performance is based upon the Company's sustaining cash cost per pound of copper produced. Sustaining cash cost per pound of copper produced is a non-IFRS financial performance measure with no standardized definition under IFRS. For further information and a detailed reconciliation of the Company's sustaining cash cost per pound of copper produced, please see the discussion under the heading "Non-IFRS Financial Performance Measures" in the Company's management's discussion and analysis of results of operations and financial condition for the year ended December 31, 2023, a copy of which is available on the Company's SEDAR+ and EDGAR profiles.

2. Results are weighted 50/50 between Manitoba and Peru.

Long-Term Incentive Plan (LTIP)

Overview of Design

As stated in our compensation philosophy, the Committee believes that long-term, equity-based compensation should form a significant portion of our NEOs' overall compensation in order to provide a strong link between compensation, performance and total shareholder returns.

The Compensation and Human Resources Committee oversees our LTIP with the objective of ensuring the alignment of our LTIP outcomes with the shareholder experience and our mid- to long-term performance and strategic goals. Our LTIP design includes a mix of equity incentives for our NEOs involving PSUs, RSUs and share options ("options").

For the grant made to our NEOs in February 2023, the percentage of the overall grant allocated to each of these LTIP vehicles was as follows:

(1) Commencing with the LTIP grant awarded in February 2024, RSUs will vest rateably over three years, while PSUs will continue to cliff vest after three years. Such change to the RSU vesting schedule will have no effect on any RSUs issued pursuant to LTIP grants prior to February 2024.

LTIP awards are granted at a target value, being a percentage of base salary determined by the Board. The award is then multiplied by the percentage of the overall LTIP grant allocated to PSUs, RSUs, and options, then divided by (in the case of PSUs and RSUs) the share price at the time of grant, or (in the case of options) the price of an option at the time of grant (as determined by the Committee using a Black-Scholes valuation methodology). An example of how the target LTIP grant applies to Mr. Kukielski's 2023 award is as follows:

Performance Share Units

PSUs are notional units that are redeemable for a Hudbay common share or a cash amount equal to the value of a common share at the vesting date. PSUs will vest at the end of three years. The units are subject to performance and vesting conditions such that all units will be forfeited if a threshold level of performance is not met. Conversely, additional units will be granted (to a maximum of 200% of the initial grant) if performance over the three-year vesting period is above the target. The performance conditions are based (as to 75% of the PSUs) on total shareholder return compared to a peer group (Relative TSR) and (as to 25%) return on invested capital (ROIC). The Committee believes that the use of Relative TSR and ROIC in the PSUs will align pay outcomes with the shareholder experience and encourage effective capital allocation.

Relative TSR Multiplier (75% of PSUs)

The number of PSUs that vest is determined in part by reference to total shareholder return ("Hudbay TSR") generated by the Company over the performance period, as compared to a peer group (the "Performance Peer Group"). The Performance Peer Group for 2023 consists of the following base metals mining issuers:

The Relative TSR multiplier will be calculated over the performance period with reference to both the annual Relative TSR and a three-year cumulative Relative TSR, on a combined basis as follows:

• 10% annual Relative TSR for year 1 of the Performance Period
• 10% annual Relative TSR for year 2 of the Performance Period
• 10% annual Relative TSR for year 3 of the Performance Period
• 70% three-year cumulative Relative TSR for the Performance Period

The calculation of the Hudbay TSR and the peer group TSR will include the appreciation of the price of the respective shares along with payments of dividends and other returns of value.

The Relative TSR Multiplier for a specific period is calculated as follows, linearly interpolated for performance between the specified levels:

Return on Invested Capital (ROIC) Multiplier (25% of PSUs)

ROIC is determined by way of a single three-year average, calculated as follows:

The ROIC Multiplier for a specific period is calculated as follows:

(1) Performance objective targets are reviewed on an annual basis.

The ROIC Multiplier will be linearly interpolated for amounts between (a) 6% and 7.4%, and (b) 7.4% and 9.5%. The performance objective targets for the 2023 grant were set with reference to current and past performance and a view to improve return on invested capital. The performance objective targets are reviewed each year.

Restricted Share Units

Restricted Share Units are like PSUs in that they are notional units that are redeemable for a Hudbay common share or a cash amount equal to the value of a common share at the vesting date. However, they are not subject to performance conditions that can increase or decrease the number of units that vest. Instead, the only vesting condition is time in that the units vest at the end of a specified period provided the recipient remains employed by the Company at the time of vesting. For the 2023 grant (and in prior years), RSUs will vest after a period of three years. Commencing with the 2024 grant, RSUs will vest rateably over a period of three years (i.e., one third per year).

Options

Share options are widely used as a minority component in an LTIP program, both among our mining peers and among TSX60 issuers. The Committee believes using share options as a balanced component of the LTIP mix will support the attraction and retention of members of the executive and broader management team.

The options vest in equal installments over three years and will remain exercisable for seven years.

The PSUs and RSUs granted in early 2023 were granted under Hudbay's Long-Term Equity Plan and the options were granted under our Share Option Plan. Summaries of these plans are included at Schedule "B".

2024 LTIP Grant

For the LTIP grant made to our NEOs in February 2024, the grants involved the same blend of PSUs, RSUs and options as were issued in 2023, in each case with substantially the same terms as in 2023, except as it relates to the three year rateable vesting for the RSUs (each as described above).

Other Compensation and Perquisites

Retirement Benefits

In addition to rewarding employees for long service to Hudbay, the Committee recognizes that retirement benefits are required to make our compensation program competitive. For details on our retirement plans, see "Description of Pension Plans".

Employee Share Purchase Plan

We maintain an Employee Share Purchase Plan ("ESPP") for our executives and other eligible employees. Pursuant to the ESPP, participants may contribute between 1% and 10% of their pre-tax base salary to acquire Hudbay shares, which are acquired through open-market purchases. We make a matching contribution of 75% of the participant's contribution, one-third of which is immediately applied toward the tax withholding obligation on our contribution. Shares purchased with our contribution may not be sold for 12 months and participants are subject to further restrictions on the number of transactions they may make and changes in their elected contribution.

Perquisites and Other Benefits

Perquisites and other benefits are intentionally limited and may include fitness memberships, comprehensive medical examinations, life and accident insurance, parking and other subsidies and entitlements for executives who relocate at Hudbay's request.

CEO COMPENSATION

2023 Compensation

Mr. Kukielski's target compensation as President and CEO was set with reference to the median compensation paid to the CEOs in our compensation benchmarking group. The actual total direct compensation received by Mr. Kukielski in respect of 2023 is shown in the table below:

1. Mr. Kukielski's actual STIP award is based on his weighted average performance score, being 20% individual and 80% corporate.

2. The LTIP value is comprised of 50% PSUs, 25% RSUs and 25% Options, as described in "2023 CEO LTIP Award", below.

Eighty percent of our CEO's STIP is based on the corporate score and twenty percent is based on his individual performance objectives. Mr. Kukielski's 2023 objectives were focused on enhancing stakeholder communications, reviewing strategy, advancing ESG initiatives, managing uncertainty and enhancing our company culture and people strategy. His performance against these objectives was assessed as 110/100 which, when combined with the corporate performance score, resulted in a combined score of 119.6%.

The factors underlying Mr. Kukielski's performance score are as follows:

2023 CEO STIP Award

The following table shows the target and actual STIP awarded to Mr. Kukielski with respect to his 2023 performance.

2023 CEO LTIP Award

The table below shows the LTIP grant made to Mr. Kukielski in early 2023 as part of his 2023 compensation.

1. The unit price to determine the number of RSUs and PSUs granted was $6.59 and was based on the trailing five-day average price of the Hudbay Shares.

2. The unit price to determine the number of options granted was $3.90 and was based upon a Black-Scholes valuation methodology. The exercise price of the options is $6.75 per share.

CEO Realized/Realizable Compensation

As part of its annual process, the Committee reviews a report on the realized and realizable pay of our CEO, which outlines the differences between his target pay and the compensation actually earned and vested (realized compensation) plus the current value of LTIP awards that have not yet vested (realizable). The table below illustrates our CEO's target total compensation compared to his realized/realizable compensation for the four completed years since his appointment as CEO in 2020. The table also shows Hudbay's total shareholder return for the period, which enables a comparison of Mr. Kukielski's compensation against the shareholders' experience. This provides the Committee with perspective on the pay-for-performance linkage over time, which provides context about the effectiveness of current pay programs and helps to inform future compensation decisions.

Table Assumptions:

1. Finalized FY 2020 PSU payout factor of 27%.

2. Finalized FY 2021 PSU payout factor of 50%.

3. For calculation of ROIC and relative TSR performance in PSUs, completed annual performance periods reflect actual performance and future performance periods were assumed at target.

4. TSR cumulative performance portion tracking measured as of December 31, 2023.

5. All equity valued using the closing price of Hudbay Shares on the Toronto Stock Exchange of $7.29 on December 29, 2023, being the final trading day of 2023.

Equity Ownership

As shown in the table below, Mr. Kukielski's total equity ownership, consisting of Hudbay shares, RSUs, PSUs and deferred share units ("DSUs"), had an aggregate market value of $9,364,317 as at March 15, 2024.

Note:

1. Based on the $9.38 closing price of Hudbay Shares on the Toronto Stock Exchange on March 15, 2024.

COMPENSATION OF NON-CEO NEOS

2023 Target Total Direct Compensation

The table below shows the target total direct compensation for Messrs. Lauzon, Lei, Donnelly and Del Rio for 2023.

Determination of 2023 Individual Performance Scores

The individual performance score for each of our non-CEO NEOs is weighted at 30% of their overall annual performance score. In determining individual performance scores, the Committee considers recommendations made by the CEO with reference to key elements of their performance within their respective areas of responsibility.

The following table shows the individual performance score of each non-CEO NEO, as well as the decision factors that were considered by the Committee in determining such scores.

2023 STIP Awards

The following table shows the actual STIP awarded to Messrs. Lauzon, Lei, Donnelly and Del Rio with respect to their 2023 performance.

1. Mr. Del Rio's base salary and STIP Award is paid in US dollars. For purposes of the table above, Mr. Del Rio's base salary and 2023 STIP Award have been converted into Canadian dollars at an exchange rate of US$1.300 per $1.00. For clarity, Mr. Del Rio earned a base salary of US$413,400 in 2023 and a 2023 STIP Award of approximately US$301,121.

2023 LTIP Awards

While the STIP payment made to our senior executives was made in early 2024, it is based on achievement of corporate and individual performance objectives in 2023 and therefore is considered compensation in respect of 2023. LTIP grants, on the other hand, are forward-looking, in that they are meant to encourage performance over the period in which the grant remains outstanding. As a result, the LTIP grant made to our executives in early 2023 is considered to be 2023 compensation.

1. The unit price to determine the number of PSUs and RSUs granted was $6.59 and was based on the trailing five-day average price of the Hudbay shares.

2. The unit price to determine the number of options granted was $3.90 and was based upon a Black-Scholes valuation methodology. The exercise price of the options is $6.75 per share.

3. Mr. Del Rio received his 2023 base salary in US dollars and for purposes of the table above, Mr. Del Rio's base salary has been converted into Canadian dollars at an exchange rate of US$1.300 per $1.00.

4. Mr. Del Rio's actual LTIP issuances in 2023 (being equal to $617,219) differ from his Target LTIP (being equal to $591,162) due to the prevailing exchange rate at the time of LTIP issuance versus the prevailing exchange rate to determine Mr. Del Rio's base salary.

2023 Total Direct Compensation

The table below shows the actual total direct compensation for Messrs. Lauzon, Lei, Donnelly and Del Rio for 2023.

1. The LTIP value is comprised of 50% PSUs, 25% RSUs and 25% Options, as described in "2023 LTIP Awards", above.

2. Mr. Del Rio's base salary and STIP Award are paid in US dollars. For purposes of the table above, Mr. Del Rio's base salary and 2023 STIP Award have been converted into Canadian dollars at an exchange rate of US$1.300 per $1.00. For clarity, Mr. Del Rio earned a base salary of US$413,400 in 2023 and a 2023 STIP Award of approximately US$301,121.

3. Mr. Del Rio's actual LTIP issuances (being equal to $617,219) differ from his Target LTIP (being equal to $591,162) due to the prevailing exchange rate at the time of LTIP issuance versus the prevailing exchange rate to determine Mr. Del Rio's base salary.

PERFORMANCE GRAPHS

Shareholder Experience

The following graph compares the yearly percentage change in the cumulative total shareholder return  on the Toronto Stock Exchange for $100 invested in Hudbay Shares on December 31, 2018 against the cumulative total shareholder return of the S&P/TSX Composite Index, relative year-over-year changes in copper price, and the median performance of a custom index consisting of the following peers: Antofagasta, Atalaya Mining, Capstone Copper, Copper Mountain, Ero Copper, First Quantum, Freeport McMoRan, Imperial Metals, Ivanhoe Mines, Lundin Mining, Nexa Resources, Sandfire Resources, Taseko Mines, Teck Resources and 29 Metals.

The trend shown in this graph is generally consistent with the realized and realizable compensation of our executive officers over the same period, as the value of vesting LTIP awards is directly linked to our share price performance. In 2019, our corporate scorecard included a modifier that adjusted scores upward or downward based on our relative TSR against a group of copper-producing peers. Our negative TSR in those years was reflected in our corporate score and resulted in reduced STIP and LTIP awards in those years. Starting in 2020, we introduced PSUs into our LTIP program and removed the TSR modifier from our corporate scorecard. From that point forward, our executive compensation more closely matched our share price performance, particularly relative to our peers as the number of PSUs that vest will be reduced in periods when our relative share price is behind that of the peer group, and the value of awards that do vest is determined by our share price at the time of vesting.

Executive Compensation Tables

Summary Compensation Table

The following table shows the compensation received in or in respect of the financial years ended December 31, 2023, 2022 and 2021 by each of the NEOs. In the annual incentive plan column of our Summary Compensation Table, the awards disclosed for 2023, 2022 and 2021 are the STIP amounts approved by the Board and awarded in early 2024, 2023 and 2022, respectively, in respect of the prior year's performance.

As described above under "Long-Term Incentive Plan (LTIP)", LTIP awards are granted at their target value and the ultimate value to be realized from LTIP awards is based entirely on the Company's future performance, starting in the grant year. As such, the "Share-based awards" and "Option awards" in the Summary Compensation Table for 2021, 2022 and 2023 represent the grant date value of the RSUs and PSUs (in the case of share-based awards) and share options (in the case of option awards) that were granted in February 2021, February 2022, and February 2023 respectively, and are considered part of each NEO's 2021, 2022 and 2023 compensation.

1. Share-based awards represent RSUs and PSUs granted in each year. PSUs are subject to a multiplier based on future performance as discussed under "Long Term Incentive Plan (LTIP)".

2. Mr. Del Rio ceased accruing pensionable service at June 13, 2017 due to the foreign service limits prescribed by the provisions of the Company's defined benefit plan and, therefore, Mr. Del Rio had his benefit frozen as of June 13, 2017 under such plan. Separately, Mr. Del Rio has elected to join our 401(k) retirement savings program in the United States, pursuant to which the Company will match 50% of the first 6% of Mr. Del Rio's voluntary contributions, subject to the contribution limits set by the IRS. In 2023, the compensatory value of Mr. Del Rio's 401(k) contributions was equal to US$9,900 and the total ending balance as at December 31, 2023 was US$65,283.

3. Only Mr. Lauzon and Mr. Del Rio received perquisites in the applicable periods that in the aggregate amounted to greater than $50,000 in any such period. Such perquisites were provided to Mr. Lauzon and Mr. Del Rio in connection with their 2022 appointments to Chief Operating Officer and Vice President, South America and USA, respectively, and relocations resulting from such appointments. Mr. Lauzon received the following perquisites during 2023, 2022 and 2021, which totaled approximately $70,760, $218,119 and $226,344, respectively: relocation payments and relocation costs, expat allowances and housing allowances. Mr. Del Rio received the following perquisites during 2022 and 2021, which totaled approximately $456,754 and $383,457, respectively: relocation payments, expat allowances, travel allowances and housing allowances. Mr. Del Rio did not receive perquisites greater than $50,000 in 2023.

4. In addition to perquisites, amounts in this column include but are not limited to vacation pay, company contributions under our Employee Share Purchase Plan, and the payment of dividend equivalents on share units held by the NEOs.

5. Mr. Lauzon was appointed as Chief Operating Officer effective January 4, 2022. Prior to such date, Mr. Lauzon served as Vice President, Arizona Business Unit and, while serving in such role, received his base salary in US dollars. Therefore, for the purposes of the table above, Mr. Lauzon's base salary in 2021 has been converted into Canadian dollars at the applicable prevailing exchange rate.

6. Mr. Lei was appointed as Chief Financial Officer effective October 13, 2022. Prior to such appointment, Mr. Lei's base salary was equal to $492,774 and after such appointment, Mr. Lei's base salary increased to $510,000. In the table above, Mr. Lei's base salary denotes the actual prorated base salary for Mr. Lei in 2022.

7. Mr. Del Rio was promoted to Senior Vice President, South America and USA in March 2023.

8. Includes a special grant to Mr. Del Rio of 64,654 RSUs in February 2022, issued concurrently with the Company's LTIP grant and with a value of $634,900, being equal to US$500,000 on the date of issuance using the prevailing exchange rate of US$1.2698 per $1.00. This special grant was made to Mr. Del Rio in connection with his promotion in 2022 to Vice President, South America & USA and as a retention incentive given his valued role in the organization.

Incentive Plan Awards

The following table provides information regarding the incentive plan awards for each NEO outstanding as of December 31, 2023.

Outstanding Option-based Awards and Share-based Awards

1. Based on the closing price of Hudbay Shares on the Toronto Stock Exchange of $7.29 on December 29, 2023, being the final trading day of 2023.

2. Reflects the number of PSUs and RSUs that have not vested. The actual number of PSUs that vest on the applicable entitlement date may be greater or less than the number presented in this table based on the multiplier effect described in this CD&A. "SUs" refer to share units, being the sum of PSUs and RSUs.

3. Excludes options which have been exercised.

4. In the case of Mr. Kukielski, this excludes the value of vested DSUs he was awarded prior to his appointment as permanent CEO.

5. With respect to the award granted on February 25, 2020, the PSUs and RSUs vested on February 25, 2023 and, as a result, there were no PSUs or RSUs granted on February 25, 2020 that had not vested as of December 31, 2023. With respect to the award granted on February 25, 2021, the PSUs and RSUs, which cliff vest in three years, vested on February 25, 2024.

6. Includes the value of all unexercised in-the-money options that have not yet vested in accordance with their terms.

Incentive Plan Awards Vested, Earned or Realized in 2023

The following table provides information regarding the value on pay-out or vesting of incentive plan awards for the financial year ended December 31, 2023.

1. Represents the PSUs and RSUs vested on February 25, 2023 pursuant to the award granted on February 25, 2020. Calculation is based on the 5-day average closing price of Hudbay Shares on the Toronto Stock Exchange of $6.64 for the five trading day period ended February 24, 2023, being the final trading day prior to the vesting date.

2. The amount represents the aggregate dollar value that would have been realized if the options had been exercised on the vesting date, based on the difference between the closing price of Hudbay Shares on the Toronto Stock Exchange on the vesting date and the exercise price. The vesting date for one third of the 2020 options that were granted to Messrs. Kukielski, Lauzon, Lei, Donnelly and Del Rio was February 25, 2023, where the closing price was $6.31 on February 24, 2023, being the final trading day prior to the vesting date, and the exercise price was $3.76. The vesting date for one third of the 2021 options that were granted to Messrs. Kukielski, Lauzon, Lei, Donnelly and Del Rio was February 25, 2023, where the closing price was $6.31 on February 24, 2023, being the final trading day prior to the vesting date, and the exercise price was $10.42. Therefore, there was no value vested with respect to the 2021 options in 2023. The vesting date for one third of the 2022 options that were granted to Messrs. Kukielski, Lauzon, Lei, Donnelly and Del Rio was February 28, 2023, where the closing price was $6.77 and the exercise price was $9.92. Therefore, there was no value vested with respect to the 2022 options in 2023.

3. None of the named executive officers listed in the chart above exercised any options in 2023 and, therefore, no named executive officer realized any money as a result of option exercises in 2023.

4. Represents the annual STIP awarded in respect of 2023.

Pension Plan Benefits: Defined Benefit Plan

1. The Company's defined benefit plan was previously closed to new entrants. As such, Messrs. Kukielski and Lauzon participate in the Company's defined contribution plan, as described below.

2. Mr. Del Rio ceased accruing pensionable service at June 13, 2017 due to the foreign service limits prescribed by the provisions of the Company's defined benefit plan and, therefore, Mr. Del Rio had his benefit frozen as of June 13, 2017 and his compensatory change is therefore nil.

Defined Contribution Plans(1)(2)(3)

1. Messrs. Donnelly and Del Rio do not participate in the Company's defined contribution plan. Separately, Mr. Del Rio has elected to join our 401(k) retirement savings program in the United States, pursuant to which the Company will match 50% of the first 6% of Mr. Del Rio's voluntary contributions, subject to the contribution limits set by the IRS. In 2023, the compensatory value of Mr. Del Rio's 401(k) contributions was equal to US$9,900 and the total ending balance as at December 31, 2023 was US$65,283.

2. NEOs may make a one-time irreversible election to receive all or a portion of their future annual incentive bonuses as supplementary pension credits under the supplemental pension plan - see "Summary of Elements of Executive Compensation - Retirement Benefits." The amounts included for Mr. Lei represent the compensatory change in value in respect of the amount of his annual incentive bonus that he has elected to receive as a supplementary pension credit.

3. For Messrs. Kukielski and Lauzon, this represents their pension benefits under the defined contribution plan, known as the MPP, including top-up amounts credited to a supplemental plan in respect of employer contributions that exceed the statutory maximum. See "Summary of Elements of Executive Compensation - Retirement Benefits".

RETIREMENT BENEFITS

Messrs. Lei, Donnelly and Del Rio participate in our defined benefit pension plan, although Mr. Del Rio ceased accruing pensionable service at June 13, 2017 due to the foreign service limits prescribed by the provisions of our defined benefit plan and, therefore, Mr. Del Rio had his benefit frozen as of June 13, 2017. Our defined benefit pension plan was closed to new participants in 2015.

The defined benefit plan is based on 2% of the average of the member's earnings during the 36 consecutive months of continuous service within the ten-year period immediately preceding the member's retirement, death or termination of continuous service in which the highest average is attained, multiplied by the member's credited service. The benefit is normally payable at age 62 but can be paid up to 10 years earlier on a reduced basis (reduction of 4.8% per year for each year that retirement precedes age 62). Members in the pension plan may elect to make optional ancillary contributions to the plan in order to enhance the ancillary features of their pension. The cost of additional benefits is fully paid by the member and contributions cannot exceed an annual maximum of the lesser of 9% of the member's earnings, or $22,672 for 2023.

The formula contains a partial offset for the Canada Pension Plan benefit. The pension is payable for life with a guaranteed period of five years. Pensions in excess of the Income Tax Act (Canada) maximum pension limits are provided under the defined benefit component of our supplemental pension plan. Our defined benefit plan has been closed off to new entrants and all new non-unionized employees and executives in Canada participate in our defined contribution pension plan.

Messrs. Kukielski and Lauzon participate in our Money Purchase Plan ("MPP"), a defined contribution pension plan. Under the MPP, they receive an annual employer contribution equal to 12% of their base salaries. The MPP does not permit voluntary contributions by executives. When the statutory annual maximum contribution is reached, the balance of the employer contribution is credited to a notional account that is indexed to actual fund performance and secured by a letter of credit.

NEOs may also make a one-time irreversible election to reduce their eligibility to participate in all or a portion of the annual incentive bonus plan (STIP) in exchange for eligibility for supplementary pension credits under the defined contribution component of our supplemental pension plan. Supplementary pension credits are determined and awarded at the same time as annual incentive bonuses. The accounts are notional accounts which are secured with a letter of credit held in trust by a financial institution. The accounts are credited with interest equal to the annual yield rate of Government of Canada marketable bonds with average yields over 10 years. We do not match or otherwise make contributions to this defined contribution component of the supplemental pension plan.

Separately, Mr. Del Rio has elected to join our 401(k) retirement savings program in the United States, pursuant to which the Company will match 50% of the first 6% of Mr. Del Rio's voluntary contributions, subject to the contribution limits set by the IRS. In 2023, the compensatory value of Mr. Del Rio's 401(k) contributions was equal to US$9,900 and the total ending balance as at December 31, 2023 was US$65,283.

Employment Agreements

Each of our current NEOs is party to an employment agreement with our Company. The NEOs' employment agreements establish their base salary and right to participate in our annual incentive bonus, long-term incentive, pension and benefit plans. The tables below summarize the payments and benefits to which our CEO and other NEOs are entitled under their respective employment agreements following their involuntary termination without cause, or resignation for certain specified events, defined as "good reason", including but not limited to a substantial change in the employment conditions or duties of the NEO that adversely affects the extent, nature or status of his responsibilities, any material reduction in the NEO's base salary, any transaction that results in a change in the status of Hudbay as a publicly-listed entity to one that is privately held, following which he is not appointed to continue in the same role, or any requirement that the NEO relocate. Under the NEOs' employment agreements, a termination without cause following a change of control is not treated differently than a termination without cause in other circumstances.

Each of our NEOs is required by their respective employment agreements to not solicit officers, employees or agents of Hudbay for 12 months following the termination of their employment and they are also required to maintain the confidentiality of our confidential information. In addition, Mr. Kukielski is subject to a non-compete provision, which requires that, for six months following his voluntary or involuntary departure from the Company, he will not serve as an officer, employee, contractor or service provider to a competitor in the jurisdictions where the Company carries on business.

Termination Entitlements: CEO

Termination Entitlements: Non-CEO NEOs

Payments on Termination

The following table provides details regarding the estimated payments to each of the NEOs as at December 31, 2023 assuming termination without cause on that date:

1. This represents the market value of the share unit (RSU and PSU) awards and the "in the money" value of all unexercised options, in each case, granted in 2020, 2021, 2022 and 2023, as applicable, based on the closing price of the Hudbay Shares on the Toronto Stock Exchange of $7.29 on December 29, 2023, being the final trading day of 2023. For further information, see "Executive Compensation Tables - Incentive Plan Awards" above.

2. Assumes that all of the outstanding PSUs will vest at 100% target.

3. In the case of Mr. Kukielski, this excludes the value of vested DSUs he was awarded prior to his appointment as permanent CEO.

Double-Trigger Payment on Termination

None of our NEOs are entitled to any payments or accelerated vesting of equity-based awards in a circumstance where there is a change of control and they are not terminated or they do not resign for "good reason", as described in more detail under "Employment Agreements" above. Such entitlements will only arise if their employment is terminated.

Director Compensation

Our director compensation program compensates non-executive directors (for purposes of this section, "Directors") for the time and effort they are expected to devote to Company matters. Executive directors (currently only our CEO) are compensated in their capacity as executives only and do not receive additional compensation for serving on the Board.

2023 Director Compensation

The fees payable to our directors in respect of 2023 are shown in the table below:

Equity-based compensation for our Directors is awarded in the form of deferred share units (DSUs). DSUs, which are granted pursuant to our Directors' Deferred Share Unit Plan, track the value of the Hudbay Shares. DSUs are vested at the time of grant but they are not paid out until after a Director departs from the Board, at which time they are paid out in cash equal to the number of DSUs held multiplied by the price of the Hudbay Shares at the time the DSUs are paid. When dividends are paid on our Hudbay Shares, holders of DSUs receive dividend equivalents, which entitle the holder to a number of additional DSUs equal to the number of DSUs held multiplied by the per share amount of the dividend, divided by the price of our common shares at the time the dividend is paid. Ensuring that Directors have an equity interest in Hudbay helps to align the interests of our Directors with the long-term interests of our shareholders and is consistent with our desire to implement best practices in our compensation programs. To further align their interests with those of our shareholders, Directors may elect to have all or a portion of their cash retainer and other fees payable to them in DSUs.

2024 Changes to Directors Compensation

In 2023, the Committee completed a review of our director compensation program. At the Committee's direction, Hugessen reviewed our directors' compensation against that of the peer group, which is the same peer group used for executive compensation benchmarking (see "Executive Compensation Overview - Compensation Peer Group"). Hugessen's benchmarking indicated that Hudbay's combined cash and equity retainers for directors were well below the market median. Hugessen also noted that Hudbay's directors receive a greater proportion of their overall fees in equity compared to its peers. Accordingly, the Committee recommended to the Board, and the Board approved, an increase in the directors' annual cash retainer from $85,000 to $95,000.

In addition, Hugessen's benchmarking indicated that the Board Chair's combined cash and equity compensation was positioned significantly below the median. At the Committee's recommendation, the Board approved an increase in the Chair's overall retainer of $45,000, split equally between cash and equity. These changes were effective January 1, 2024.

Director Compensation Table

The following table sets out the compensation paid to each of our non-executive Directors in respect of the year ended December 31, 2023.

1. Represents fees and retainers paid in cash. Directors can elect to have all or a portion of their cash retainers and meeting fees paid to them in DSUs.

2. Represents fees and retainers paid in DSUs. The DSUs are vested at the time of grant and become payable to the directors upon their departure from the Board.

3. Represents amounts paid in additional DSUs as dividend equivalents following payments of our $0.01 per share dividend on March 24, 2023 and September 22, 2023.

4. Mr. Howes ceased to be a Director of the Company effective as of May 10, 2023.

5. Ms. Hull was appointed as a Director of the Company effective as of June 20, 2023.

6. Mr. Lafond was elected as a Director of the Company effective as of May 10, 2022.

7. Ms. Rogers was appointed as a Director of the Company effective as of June 20, 2023.
