A MESSAGE FROM YOUR

President & CEO

Hecla has a remarkable legacy of operational excellence, innovation, and a strong commitment to responsible mining and sustainable practices.

Rob Krcmarov

President, CEO and Director

To My Fellow Hecla Shareholders:

It is my pleasure to invite you to participate in the Annual Meeting of Shareholders of Hecla Mining Company to be held on May 21, 2025 at 10:00 a.m. PDT. This year’s Annual Meeting of Shareholders will be conducted exclusively online in a virtual meeting format, allowing shareholders to listen, vote and submit questions conveniently from their own home or remote location.

Since joining Hecla six months ago, I have been privileged to work alongside our exceptional team of employees and Board of Directors, who have made the transition for me and my family smooth and enjoyable. My initial impressions of our Board have been confirmed: it is a cohesive group committed to independent, strong governance, and shareholder value creation.

I have now visited all four of our mining operations and engaged extensively with our employees, investors, and other stakeholders to develop a clearer vision for Hecla’s future and some of the opportunities that are available to us. Our high-quality, long-life mines in premier North American jurisdictions provide an exceptional foundation for our future. We expect Greens Creek and Lucky Friday to continue delivering strong performances with robust cash flows and attractive margins. Keno Hill represents our primary growth opportunity, and while ramp-up challenges remain, we have identified a disciplined path to achieving sustained profitable production through targeted investments and operational improvements. Casa Berardi has attractive potential with investment and permitting success, even as we consider where it fits in Hecla’s near-term and long-term future.

Looking ahead, we are focusing on four key strategic pillars with financial discipline at their core. First, we are committed to achieving operational excellence through relentless improvement, including implementing standardized operating systems across all sites to drive efficiency, as well as continuous improvement in cost control. Second, we are optimizing our portfolio to maximize value. We have begun this journey with our strategic review of Casa Berardi, and we are also evaluating our extensive portfolio of exploration assets and investments to unlock value. We will only allocate capital to projects exceeding our minimum return threshold. Third, we are intensifying our focus on financial discipline and shareholder returns. We are implementing a rigorous capital allocation framework centered on free cash flow generation and return on investment metrics with clear hurdle rates. Fourth, our strategic focus on silver production in the U.S. and Canada continues to deliver exceptional value. With the largest silver reserve base in North America and operations concentrated in tier-one jurisdictions, we are strongly positioned to meet growing demand from green technology and renewable energy sections.

While our focus is firmly on the future, I want to acknowledge our recent past. All of us at Hecla say thank you to Cassie Boggs for her continued service as our Chair of the Board, and for serving as interim President and CEO for a portion of 2024. Along with our other Directors, her steady hand guided the Company deftly through transition. We also say a thank you to Chuck Stanley for stepping up as Hecla’s Independent Lead Director while Cassie managed the Company’s day-to-day operations. The additions of Mark Board and Jill Satre to our Board in 2024 have brought fresh perspectives while maintaining our commitment to independence, strong governance, and decreasing the average tenure of the Board.

ii | 2025 Proxy Statement |  |  |  |

Finally, I again commend Hecla’s workforce, the driving force behind our 134-year legacy of success. I look forward to working with all of our stakeholders as we continue to navigate change, with excitement for what the future holds for the largest U.S. and Canadian silver producer.

As your new President, Chief Executive Officer and Director, I want to thank you for your continued confidence in Hecla and I

look forward to reporting on our progress against these strategic priorities.

Rob Krcmarov

President, CEO and Director

Shareholder Engagement

We have long believed that the delivery of long-term value requires regular dialogue with, and accountability to, our shareholders. As a result, our management team participates in numerous investor meetings throughout the year to discuss our business and strategic priorities. These meetings include in-person, telephonic, and webcast engagements, as well as investor conferences, and can occur in a group or one-on-one settings. Our core shareholder engagement team includes our Senior Vice President – Chief Administrative Officer, Senior Vice President – General Counsel and Secretary, Vice President – Corporate Development, Vice President – Investor Relations and Treasurer, and Assistant Secretary. If requested by a shareholder, our chairpersons of each committee of the Board are available to join any shareholder engagement.

|  | 1 Solicit and receive feedback from shareholders on governance practices and trends, board composition, executive compensation, sustainability, human capital management and other shareholder priorities.
| 2 Hecla’s engagement team reports to Board to review shareholder feedback and use information gathered from the winter engagement to, when appropriate, enhance disclosures and revise governance practices, executive compensation program, sustainability practices or other programs and policies.
| 3 Engage with institutional holders, analysts, and other investors during the year on other topics of interest. In 2024, management conducted approximately 20 presentations for analysts and investors, held approximately 150 one-on-one and group meetings with investors and hosted four quarterly conference calls with investors and analysts allowing for questions and answers with management. In addition, the Company responds to questions from investors and analysts by telephone and email throughout the year.
| 4 Receive and publish voting results from annual meeting which helps shape our ongoing improvements and developments in governance practices, executive compensation, sustainability, and other shareholder interest areas.

In late 2024/early 2025, we sought engagement with 30 of our largest shareholders (representing approximately 239.7 million shares, and the two proxy advisory firms. We had only one shareholder request a meeting (representing approximately 2.8M shares) and six responded that they did not need to engage. One of the proxy advisory firms responded to our invitation to engage.

|  | During our engagement, we discussed: •the Board’s continued search for additional directors; •Board tenure; |  | •executive compensation; and •corporate governance matters.

Say-on-Pay In 2024, our Say-on-Pay proposal received approximately 70% support of shares voted. See Changes in Compensation Plan Design for 2025 and Results for 2024 under “Shareholder Engagement” on page 55 for more information on our shareholder engagement as it relates to executive compensation.

Corporate Governance

In our corporate governance discussions during our shareholder engagement, we discussed our Board composition and diversity. Since 2016, we have added seven new directors to our Board, including one in 2021 and three in 2024, thereby reducing the average tenure of the Board to six years. Also, out of our eight directors, three are women. We will continue to look for and add more directors as needed.

We also discussed three of our corporate governance features that may have an anti-takeover effect on the Company: (i) the inability of shareholders to call special meetings; (ii) our classified Board structure; and (iii) supermajority voting provisions in our Restated Certificate of Incorporation and Bylaws. In prior years, we have proposed amendments to our Restated Certificate of Incorporation and Bylaws to revise these three provisions, but the voting results have never been close to sufficient to implement these changes. The required vote is 80% of outstanding shares voted in favor of any such change, and we have never obtained higher than 56% of outstanding shares voted in favor. During our shareholder engagement we have unanimously heard that due to (i) the repeated failure of proposals to change these provisions at past annual meetings; (ii) the desire to improve the format and readability of our Proxy Statement; and (iii) the resources involved in printing and mailing a lengthier Proxy Statement, there are no objections if we did not include these proposals at our Annual Meeting.

The Board will continue to assess evolving best practices in corporate governance matters, including the subjects of the prior proposals discussed above. In future years, we may again include one or more of these proposals on the agenda for an Annual Meeting. Furthermore, the Board will continue to consider any formal proposals and other feedback that we receive from shareholders. And, we will continue our shareholder engagement efforts so that we can understand and appropriately react to the evolving viewpoints of our shareholders on corporate governance and other matters.

Sustainability

We are committed to prioritizing the health, safety and well-being of our workforce and host communities where we operate, meeting high standards of environmental stewardship across our operations, and respecting human rights in all our business practices. We recognize that the long-term success of the Company and sustainable value creation are dependent on integrating the Environmental, Social and Governance (“ESG”) performance factors that are most important to our stakeholders and to our business into our business strategies. Thus, we measure our ESG performance against the following benchmarks:

• |  | the Sustainability Accounting Standards Board – metals and mining standards;

• |  | relevant aspects of the Task Force on Climate-Related Financial Disclosures, Global Reporting Initiative; and

• |  | Mining Association of Canada’s Towards Sustainable Mining protocols.

We have also prioritized the United Nations Foundation Sustainable Development Goals that most directly align with our business, corporate strategy, and material sustainability issues.

More information about our ESG efforts can be found in our Sustainability Reports (“ESG Reports”) on our website at https://www.hecla.com under “Sustainability.” Note that this information is not incorporated by reference into this Proxy Statement. Forward-looking statements in this Proxy Statement and in our ESG Reports and disclosures are aspirational and not guarantees or promises that goals, targets, or projections will be met, and no assurance can be given that any commitment, expectation, initiative, or plan referenced in this Proxy Statement or in our ESG Reports and disclosures can or will be achieved or completed. You can view our 2023 Sustainability Report on our website. We expect our 2024 Sustainability Report to be available on our website in mid-May 2025.

Board Oversight and Management of Sustainability

Two committees of the Board provide primary oversight over ESG matters. The Health, Safety, Environmental and Technical Committee (“HSET Committee”) is tasked with overseeing ESG risks, strategic plans, and progress on issues that may potentially adversely impact Hecla’s operations, activities and plans. The focus is primarily on internal matters and the technical requirements of ESG matters. The Governance and Social Responsibility Committee (“Governance Committee”) is tasked with reviewing and making recommendations to the Board for ESG matters that focus primarily on policy and external matters, including strategies and reputation. Each committee relies on the activities of the other.

At the executive level, the Vice President – Sustainability, Senior Vice President and Chief Operating Officer, Vice President – Corporate Development, and Senior Vice President – Chief Administrative Officer report directly to our President and CEO and are responsible for implementing the Company’s ESG programs. At our operations, our Vice Presidents – General Managers, and other employees work toward achieving sustainability goals.

Environment

Our metals, especially silver and zinc, are critical components to green energy technologies and national security. Demand for responsibly sourced metals is growing. As the largest silver producer in the United States, Hecla is proud to supply an essential metal used in critically important markets including renewable energy technology, medical products, and military defense technology. At the same time, we recognize the importance of responsible mining to ensure that we minimize the impacts of our activities on the environment where we live and work. At each of our sites, we have implemented programs to reduce freshwater and energy consumption, reduce our carbon footprint, maintain local water quality backed by rigorous testing and monitoring, and reclaim the land once mining is complete.

We work to minimize the environmental impact of our operations through improvement of our processes. We set reduction targets for greenhouse gas emissions and energy use capturing and tracking environmental data to benchmark our operations against industry standards to provide accountability and transparency in our progress against our goals.

Risk Management

Environmental Policies, Management System, and Training

Hecla’s Environmental Policy states our commitment to complying with all applicable environmental laws and regulations that govern our facilities and going beyond them when minimal compliance does not meet Hecla’s values. We conduct structured environmental reviews and audits to assess compliance at least annually. Employees and contractors are expected to comply with all applicable internal policies, programs, standards, and procedures as outlined in our Code of Conduct.

We utilize our Environmental Management System (“EMS”) to provide consistency in our environmental programs company-wide and promote a culture of environmental awareness, innovation, and accountability across all our operations. The EMS program, which is benchmarked against ISO-14001 and complements Canada’s Towards Sustainable Mining program, is reviewed annually through internal audits and externally every three years. We are in the process of implementing the EMS at our Keno Hill operations.

As part of our environmental management programs, we are committed to ensuring that our employees receive training to raise awareness of environmental issues and our processes to reduce environmental impact. In 2024, employees company-wide received more than 4,584 hours, and contractors received more than 2,060 hours, of environmental training, focusing on job-specific environmental awareness, hazardous material management, spill response, and reporting.

Climate Change

Hecla recognizes that the impacts of climate change may create greater potential risks for our operations, including risks posed by frequent and extreme weather events such as droughts and intense rainfalls. Potential risks to our operations include higher volumes of mine contact water requiring storage and treatment, increased requirements for stormwater diversion and associated water management systems, and reduced availability of freshwater. As part of our enterprise risk management processes, we are committed to incorporating climate-related risks and opportunities into our risk management and strategic planning processes aligned with the Task Force on Climate-Related Financial Disclosures framework.

At least every three years, we conduct structured high-level risk assessments (“HLRA”) that include climate change considerations and appropriate materiality re-assessments. From these assessments, we develop site-specific management action plans that are assigned to the site management team for resolution. Each key risk identified in the HLRA response action plan is matched with an appropriate performance metric against which progress can be measured. Management and relevant employees meet quarterly with the HSET Committee of our Board to present project updates, including results from HLRAs and progress on material HLRA action plans. In 2024, we conducted an HLRA at each of our producing mines.

|  | Environmental Highlights |  |  |  |
Protecting the Environment Hecla’s responsibilities expand beyond producing essential metals, and we recognize the importance of minimizing the impact on the environments of the communities where we live and work. We are committed to minimizing the environmental footprint of our operations through continuous improvement of our processes. Integrated Environmental Working Groups Each of our sites has a Tailings, Waste and Water working group that considers, among other aspects, climate change-related impacts that could affect site operations which are then integrated into design of mine facility infrastructure. |  | Renewable Energy One of Hecla’s largest sources of electricity is renewable hydropower, and we use as much hydroelectricity as our power suppliers can provide. Currently, at our production sites: •Casa Berardi uses approximately 100% renewable hydropower to supply line power. •At Greens Creek, 91% of our electricity is sourced from the grid, of which 100% is renewable hydropower. •The energy provider at our Lucky Friday location uses a mix of both hydropower and natural gas, with 60% of electricity sourced being renewable. •Keno Hill uses 86% renewable hydropower.

Safety and Health

Hecla’s commitment to the safety and health of our workforce has been an essential part of our corporate culture for 134 years and has enabled us to build the highest reputation for safety with our employees, our communities, and within the industry. We work to operate our mines safely by promoting a deeply rooted, value-based culture, leveraging mining expertise developed over the Company’s long history, and innovating new practices that improve safety while increasing productivity. As an example, 2021 saw the development of the patented Underhand Closed Bench (“UCB”) mining method at the Lucky Friday mine. The UCB mining method has improved our ability to manage seismicity at the mine while it has also enabled us to increase production.

|  | Safety and Health Highlights |  |  |  |
Safety and Health •Safety Meetings Held: 919 •Safety and Health Training Hours: 44,850 •Implemented Safety 365, which is a renewal of the fundamental values that underpin our safety systems. |  | Safety Awards •Lucky Friday took 1st Place overall at the Central Mine Rescue Competition, including first place finishes in Field, Rope Rescue, and Team Tech, and second place in First Aid. Greens Creek took second place in Team Tech at the same competition. Zero Fatalities •In 2024, we had zero employee or contractor fatalities.

Supporting and Developing Our People

Hecla is dedicated to investing continuously in the technology, training, systems, and programs that help protect and support our people. We also strive to have our workforce at least mirror the diversity of the local demographic from which we do a majority of our hiring.

At the executive level, the Senior Vice President – Chief Administrative Officer reports directly to the CEO and is responsible for the Company’s programs to support and develop our people. At the local level, each operating site has a human resource professional whose primary role is to support and develop our people at that site.

As of December 31, 2024, Hecla employed approximately 1,830 people, of which approximately 1,070 were employed in the United States, 750 in Canada, and 10 in Mexico. The vast majority of Hecla’s employees are full-time, and approximately 320 of our employees are covered by a collective bargaining agreement. Creating greater gender diversity in a predominantly male industry remains challenging but is among our priorities.

|  | Human Capital Management Highlights |  |
Gender Diversity •10% of our workforce are women, and women hold 21% of our professional/managerial positions. 38% of our Board is made up of women. •We have implemented programs to foster the hiring and retention of women including the creation of networking opportunities with senior executives and Board members. Promoting Diverse Cultures •In 2024, approximately 112 First Nations members worked at Casa Berardi. Hecla encourages its suppliers to hire Indigenous workers and remains committed to providing opportunities to the First Nation businesses. •Our Casa Berardi mine in Quebec provides annual cultural awareness training for all department heads. Discrimination & Harassment We are committed to providing equal employment opportunities and complying with all applicable employment laws in the countries where we operate, as outlined in the “Employee Relations” section of our Code of Conduct. We hold harassment – free workplace training programs which are mandatory, and employee participation is tracked by a third party to ensure actual compliance. |  | Protecting Human Rights We support fundamental human rights in all our operations, including our supply chain, and in all jurisdictions in which it conducts business. We operate in countries where human rights laws are respected and promoted. Our Human Rights Statement discusses our commitment to conduct business in a manner consistent with the United Nations Universal Declaration of Human Rights and the United Nations Guiding Principles on Business and Human Rights. See www.hecla.com/sustainability/our-people. Education •We offer a tuition reimbursement program to assist with educational expenses for employees who are interested in furthering their education. •At Lucky Friday, we provide on-line training through OEMs to ensure our miners continually expand their skill sets. •Our Greens Creek mine funds vocational scholarship programs, tours, class and coursework, internships, and externships. •Ongoing professional development is a cornerstone of our core value of innovation and continuous improvement. Our employees are represented in a variety of industry and discipline specific bodies of knowledge, including both membership and leadership roles.

Community Engagement

Over our 134-year history, Hecla has always been a strong partner in the communities where we operate. Through the continued growth of our responsible mining operations, we provide significant social and economic benefits to our local communities. We are the largest private-sector employer and property taxpayer in each of the communities where we operate: Juneau, Alaska (Greens Creek), La Sarre, Quebec (Casa Berardi), Mullan, Idaho (Lucky Friday), and Yukon Territory (Keno Hill). Some of these operations have been part of their communities for generations.

We communicate information through a variety of methods including community meetings and postings, as well as local and social media. All materials are available in the local language with translation provided, if necessary. We disclose the results of environmental, economic, and social impact assessments and partner with local stakeholders. We also work with local stakeholders to identify opportunities for the Hecla Charitable Foundation to provide support for community initiatives.

|  | Community Engagement Highlights |  |
Engaging with Community Stakeholders •We engage with stakeholders at all our sites during the mining life cycle to be a constructive partner in the communities where we operate and deepen our understanding of local concerns and issues. Indigenous Relations •With the purchase of Alexco Resources in 2022, Hecla now has two operations and one exploration project in Canada that have benefit agreements in place with the Abitibiwinni First Nations at the Casa Berardi Mine in Quebec, the First nations of Na-Cho nyäk Dun at Keno Hill in the Yukon, and the Gitanyow nation at the Kinskuch property in British Columbia. Community Partnerships •In Montana, Hecla originated the Grizzly Corridor Project in collaboration with biologists, the U.S. Forest Service, U.S. Fish and Wildlife, and local logging contractors. On Hecla land, we strategically thinned tree density to open the canopy, thereby resulting in travel routes for bears while increased sunlight stimulates growth in the understory. •In Montana, we also partnered with the Confederated Salish and Kootenai Tribes to harvest and plant over 200,000 native shrubs and trees at our reclaimed Troy mine. •Several of our mining operations prioritize using local vendors, which helps to build service partnerships, supports local businesses, and strengthens the local economy. |  | Supporting Communities through the Hecla Charitable Foundation •Since inception, the Hecla Charitable Foundation has disbursed $5.4 million in grants focused on the four pillars of (i) community, (ii) education, (iii) health, and (iv) youth. In 2024, the Hecla Charitable Foundation donated more than $619,546 toward education, youth activities, community programs, and health services activities in communities in which we operate. Building a Skilled Workforce •At our Greens Creek mine in Alaska, we have partnered with multiple entities to create a skilled local workforce. •At Prince William Sound College in Alaska, we created a Millwright program, including full scholarships. •At the Alaska Vocational Technical Center, we provided scholarships and internships to Diesel and Electrical Tech students. •We continue to use the Mining and Petroleum Training Service in Alaska to train employees new to mining. •For our Lucky Friday workforce, we provide online training in coordination with North Idaho College through TPC Training and hands-on training by Caterpillar and Epiroc to ensure our maintenance employees continually expand their skill sets. •Hecla participated in on-site recruiting events and provided technical presentations at colleges and universities in Alaska, Idaho, Montana, Nevada, South Dakota, Washington, and Quebec. •Greens Creek proactively engages with local high schools and colleges to discuss careers at Hecla. In 2024, we participated in career fairs at high schools in Juneau, Haines, and Angoon, Alaska, as well as the Colorado School of Mines. •We made targeted outreach to Indigenous community members at the Angoon fair in Alaska and offered internships at the Greens Creek mine.

Corporate Governance Guidelines and Code of Conduct

The Board has adopted Corporate Governance Guidelines and a Code of Conduct in accordance with the U.S. Securities and Exchange Commission (“SEC”) and the New York Stock Exchange (“NYSE”) corporate governance standards. The Corporate Governance Guidelines were adopted by the Board to ensure the Board is independent from management, that the Board adequately performs its function as the overseer of management, and to help ensure that the interests of the Board and management align with the interests of our shareholders.

We believe that operating with honesty and integrity has earned trust from our shareholders, credibility within our communities and dedication from our employees. Our directors, officers and employees are required to abide by our Code of Conduct to promote the conduct of our business in a consistently legal and ethical manner. Our Code of Conduct covers many topics, including conflicts of interest, confidentiality, fair dealing, proper use of the Company’s assets, and compliance with laws, rules, and regulations. In addition to the Code of Conduct for directors, officers and employees, our President and CEO, Senior Vice President – Chief Financial Officer, Vice President – Principal Accounting Officer, and site controllers are also bound by a separate Code of Ethics.

The Governance Committee has adopted procedures to receive, retain, and react to complaints received regarding possible violations of the Code of Conduct, and to allow for the confidential and anonymous submission by employees of concerns regarding possible violations of the Code of Conduct. Our employees may submit any concerns regarding apparent violations of the Code of Conduct to their supervisor, our Senior Vice President – General Counsel and Corporate Secretary, the Chair of the Governance Committee, or through our website submission page or telephone hotline (both of which have the option to remain anonymous).

Our Code of Conduct includes an anonymous telephone hotline and secure website that employees can use to report allegations of Code violations or other misconduct. In 2024, we received one such report, which was investigated and addressed.

##### Table of Contents

Whistleblower Policy

We have a Whistleblower Policy adopted by our Audit Committee that encourages our employees, suppliers, contractors, shareholders, customers, or other stakeholders (collectively, “stakeholders”) to report to appropriate Company representatives, without fear of retaliation, any information relating to possible fraud or questionable accounting, internal controls, or auditing matters. Stakeholders may confidentially submit any concerns to the Company’s Senior Vice President – General Counsel and Corporate Secretary, or through an anonymous third-party telephone hotline and online reporting system. The goal of this policy is to discourage illegal activity and business conduct that damages Hecla’s reputation, business interests, and our relationship with stakeholders.

The Whistleblower Policy utilizes the same reporting system described on the previous page as part of our Code of Conduct.

Communications with the Board

Stakeholders wishing to communicate with our Board Chair or with the independent directors as a group may do so by delivering or mailing the communication in writing to: Board Chair, c/o Corporate Secretary, Hecla Mining Company, 6500 N. Mineral Drive, Suite 200, Coeur d’Alene, Idaho 83815. Concerns relating to accounting, internal controls or auditing matters are immediately brought to the attention of our internal auditor and overseen in accordance with procedures established by the Audit Committee with respect to such matters. From time to time, the Board may change the process by which stakeholders may communicate with the Board or its members. Please refer to our website at https://www.hecla.com, selecting the tab titled “Company” and then the tab titled “Governance & Ethics,” for any changes in this process.

Board Leadership Structure

Currently, the positions of President and CEO and Board Chair are held by separate persons. The Board believes this structure is optimal for the Company at this time because it allows the President and CEO to focus on leading the Company’s business and operations, and the Board Chair to serve as a sounding board and advisor to the President and CEO, and to lead the activities of the Board. The Board has also determined that having this structure ensures a greater role for the independent directors in the oversight of the Company, and it enhances the Board’s independence and, we believe, senior management’s accountability to the Board.

In the future, if the individual elected as Board Chair also were to be the President and CEO, the independent directors would elect an Independent Lead Director for a one-year term. This would help ensure continued robust independent leadership of the Board. This situation arose for us between May 22, 2024 through December 12, 2024 as a result of the departure of our former President and CEO, prompting our Board Chair to become Interim President and CEO and for an Independent Lead Director to be appointed. The situation was unwound when we hired our new President and CEO on November 7, 2024.

Executive sessions of independent directors are included on the agenda for every regularly scheduled Board meeting and were held at each regularly scheduled Board meeting in 2024. The executive sessions are chaired by the Board Chair. Our independent directors meet in executive sessions without management present unless the independent directors request their attendance. For the foregoing reasons, we have determined that our leadership structure is appropriate in the context of our specific circumstances.

Board Refreshment

In accordance with our Corporate Governance Guidelines, the Governance Committee reviews annually the composition and size of the Board, recognizing the importance of refreshment to maintain a balance of tenure, diversity, skill sets and experience. Our Board currently consists of eight members, seven of whom the Board has affirmatively determined are independent. There are three current Class III directors whose terms will expire at the Annual Meeting: Charles B. Stanley, Alice Wong, and Jill Satre (who was added to the Board in October 2024). Since 2021, we have recruited four new Board members (50% of the Board), reflecting our continued process of Board refreshment. These four additions to our Board are consistent with our objective to have a Board with expansive and diverse experience, a deep understanding of the challenges and opportunities associated with our business and a focus on value creation and sustainability for the benefit of all stakeholders. Our director recruitment efforts are ongoing and further additions to the Board are anticipated.

Identifying and Evaluating Nominees for Director

Director Selection Process

1 2 3 4 CANDIDATE GOVERNANCE BOARD OF SHAREHOLDERS RECOMMENDATIONS COMMITTEE DIRECTORS Vote on nominees at From shareholders, Evaluates the Boards Discusses, analyzes Annual Meeting management, directors, needs and screens and independence, and and search firms interviews candidates selects nominees for election Reviews qualifications and expertise, tenure, regulatory requirements, and diversity Recommends nominees to the Board

The Governance Committee uses a variety of methods for identifying and evaluating nominees for director. The Governance Committee is responsible for ensuring that the composition of the Board accurately addresses the needs of our business. In the event vacancies are anticipated, or arise, the Governance Committee considers various potential candidates for director. Candidates may come to the attention of the Governance Committee through current Board members, professional search firms, shareholders, or other persons. Consideration of new director nominee candidates typically involves a series of internal discussions, review of information concerning candidates and interviews with selected candidates. The Governance Committee then determines the best qualified candidates based on the established criteria and recommends those candidates to the Board for appointment until such time as they stand for election by our shareholders.

While the Governance Committee and our Board prioritize maintaining a board that is comprised of directors with a diverse set of skills, backgrounds, experiences, and perspectives, they also recognize the importance of balancing these qualifications with the overall tenure of directors in their long-term approach to board refreshment. The fresh viewpoints and philosophies newer directors bring, coupled with the valuable experience and institutional knowledge the longer-tenured directors possess, benefits the Board and its overall contribution to the Company and our shareholders.

Since 2021, the Board has added four highly qualified directors (seven since 2016) who bring insight to areas such as mining, international business, acquisitions, operations, legal, risk management, geology, engineering, finance, and tax. We have one longer-tenured director (Mr. Stanley) who has extensive knowledge of our operations and the perspective of overseeing our business activities through economic cycles and across differing competitive environments.

We hold the view that the continuing service of qualified incumbents promotes stability and continuity in the boardroom, contributing to the Board’s ability to work as a collective body, while giving us the benefit of familiarity and insight into our affairs that our directors have accumulated during their tenure. Recent additions to the Board provide new perspectives and diversity, while our director who has served for a number of years brings experience, continuity, institutional knowledge, and insight into the Company’s business and industry. Directors with relevant business and leadership experience provide the Board with a useful perspective on business strategy and significant risks, and an understanding of the challenges facing the business. Accordingly, the process for identifying nominees reflects our practice of re-nominating incumbent directors who continue to (i) satisfy the Governance Committee’s criteria for membership on the Board, (ii) makes important contributions to the Board, and (iii) consenting to continue their service on the Board. Directors should also be able to commit the requisite time for preparation and attendance at regularly scheduled Board and committee meetings, as well as be able to participate in other matters necessary to ensure good corporate governance is practiced.

The Governance Committee reviews annually with the Board the composition of the Board as a whole and recommends, if necessary, measures to be taken so that the Board reflects the appropriate balance of knowledge, experience, skills, expertise, and diversity required for the Board as a whole, and contains at least the minimum number of independent directors required by applicable laws and

regulations. Board members should possess such attributes and experience as are necessary for the Board as a whole and contain a broad range of personal characteristics, including diversity of backgrounds, management skills, mining, accounting, finance, and business experience. Our current directors exhibit a effective mix of skills, experience, diversity, and perspective. Summarized below is a description of why each core competency is important for service on Hecla’s Board.

In general, and as more fully outlined in our Bylaws and Corporate Governance Guidelines, in evaluating director candidates for election to our Board, the Governance Committee will: (i) consider if the candidate satisfies the minimum qualifications for director candidates as set forth in the Corporate Governance Guidelines; (ii) consider factors that are in the best interests of the Company and its shareholders, including the knowledge, experience, integrity and judgment of each candidate; (iii) consider the contribution of each candidate to the diversity of backgrounds, experience and competencies which the Board desires to have represented, with such diversity being considered among the other desirable attributes of the Board; (iv) assess the performance of an incumbent director during the preceding term; (v) consider each candidate’s ability to devote sufficient time and effort to his or her duties as a director; (vi) consider a candidate’s independence and willingness to consider all strategic proposals; (vii) consider any other criteria established by the Board and any core competencies or technical expertise necessary to manage and direct the affairs and business of the Company, including, when applicable, to enhance the ability of committees of the Board to fulfill their duties; and (viii) determine whether there exists any special, countervailing considerations against nomination of the candidate.

Director Qualifications, Evaluation, and Nomination

The Governance Committee believes nominees for election to the Board should also possess certain minimum qualifications and attributes. The nominee must: (i) exhibit strong personal integrity, character and ethics, and a commitment to ethical business and accounting practices; (ii) not be involved in ongoing litigation with the Company or be employed by an entity engaged in such litigation; and (iii) not be the subject of any ongoing criminal investigations in the jurisdiction of the United States, any state, or internationally, including investigations for fraud or financial misconduct.

In connection with the director nominees who are up for election at the Annual Meeting, the Governance Committee also considered the nominee’s role in: (i) overseeing the Company’s efforts in complying with its SEC disclosure requirements; (ii) assisting in improving the Company’s internal controls and disclosure controls; (iii) assisting with the development of the strategic plan of the Company; and (iv) working with management to implement the Company’s strategic goals and plans. Directors are expected to exemplify high standards of personal and professional integrity and to constructively challenge management through their active participation and questioning. Our Bylaws and Corporate Governance Guidelines provide that a director will not be nominated for re-election after their 75th birthday.

In addition to fulfilling the above criteria, each nominee for election to the Board at the upcoming Annual Meeting brings a strong and unique background and set of skills to the Board, giving the Board competence and experience in a wide variety of areas, including corporate governance, senior leadership, legal, geology, accounting, finance, mining, exploration, and board service. The Governance

##### Table of Contents

Committee has reviewed the nominees’ overall service to the Company during their terms, including the number of meetings attended, level of participation and quality of performance.

Majority Voting for Directors and Director Resignation Policy

Our directors are elected by majority vote (plurality in the case of a contested election). Our Corporate Governance Guidelines include a director resignation policy. The policy provides that any director who is not elected by a majority of votes cast shall tender his or her resignation to the Governance Committee. The Governance Committee will recommend to the Board whether to accept or reject the resignation offer, or whether another action should be taken. In determining whether to recommend that the Board accept any resignation offer, the Governance Committee will consider all factors believed relevant by it. The Board will act on the Governance Committee’s recommendation within 90 days following certification of the election results. In deciding whether to accept the resignation offer, the Board will consider the factors considered by the Governance Committee and any additional information and factors that the Board finds relevant. If the Board accepts a director’s resignation offer pursuant to this process, the Governance Committee will recommend to the Board and the Board will thereafter determine whether to fill such vacancy or reduce the size of the Board. Any director who tenders his or her resignation pursuant to this provision will not participate in the proceedings of either the Governance Committee or the Board with respect to his or her own resignation offer. If a director’s resignation is not accepted by the Board, the director shall continue to serve until the next annual meeting of shareholders or until his or her successor is duly elected and qualified, or his or her earlier resignation or removal.

Diversity

The Company’s Corporate Governance Guidelines provide the Board should include individuals with a diverse range of experiences to give the Board depth and breadth in the mix of skills represented. The Board seeks to include diversity in professional experience, skills, industry background, race/ethnicity, national origin, and gender, as well as the ability of directors (and candidates for director) to devote sufficient time to performing their duties in an effective manner.

Number of Board of Directors

Our Bylaws require the Board to have not less than five nor more than nine members. The size of the Board may be increased or decreased within that range from time-to-time by resolution approved by the affirmative vote of a majority of the Board. On February 22, 2024, the Board increased the size of the Board from six members to seven members (Mr. Board). On May 22, 2024, the Board decreased the size of the Board from seven to six members to reflect a departure (Mr. Baker). On October 16, 2024, the Board increased the size of the Board from six to seven members (Ms. Satre), and on November 7, 2024, the Board increased the size of the Board from seven to eight members (Mr. Krcmarov).

Board’s Role in Oversight of Strategy and Risk Management

Our Board is engaged and involved in overseeing our strategy and takes an active role in risk oversight. The Governance Committee is responsible for overseeing corporate governance and ESG risks and opportunities. In addition, the HSET Committee supports the furtherance of Hecla’s commitment to adopt best practices in mining operations, promote a healthy and safe work environment and advance environmentally sound and socially responsible resource development. The Board:

• |  | oversees the strategic direction of the Company, and in doing so considers the potential rewards and risks of our business opportunities and challenges and monitors the development and management of risks that impact our strategic goals;

• |  | is responsible for risk oversight at the Company, with reviews of certain areas conducted by the relevant Board committees that regularly report to the full Board; and

• |  | in its risk oversight role, reviews, evaluates, and discusses with appropriate members of management whether the risk management processes designed and implemented by management are adequate in identifying, assessing, managing, and mitigating material risks facing the Company, including financial, operational, social, and environmental risks.

The Board believes that full and open communication between senior management and the directors is essential to effective risk oversight. Our Board Chair regularly meets with our President and CEO on a variety of matters, including business strategies, opportunities, key challenges, and risks facing the Company, as well as management’s risk mitigation strategies. Senior management attends all regularly scheduled Board meetings where they conduct presentations on various matters involving our operations and are available to address any questions or concerns raised by the Board on risk management-related or other matters. Following consideration of the information presented by management, the Board provides feedback and makes recommendations, as needed, which is designed to help minimize the Company’s risk exposure. To the extent any risks identified by each standing committee of the Board are material or otherwise merit discussion by the whole Board, the respective committee chair will raise such risks at the next scheduled meeting of the Board, or sooner if merited.

For the foregoing reasons, we have determined that our risk oversight is appropriate in the context of our specific circumstances, risk management efforts, and the Board’s administration of its oversight function. The chart below provides an overview of the allocation of risk management responsibilities among the Board committees.

The criteria used when assessing the qualifications of potential President and CEO successors include, among others, strategic vision and leadership, operational experience, financial management, executive officer leadership development, ability to motivate employees, and an ability to develop an effective working relationship with the Board.

Emergency Succession Plan

Board and Committee Independence; Audit Committee Financial Expert

Our Corporate Governance Guidelines provide that the Board will have a majority of directors who meet the criteria for independence as defined in the NYSE rules. Based on information solicited from each director, and upon the advice and recommendation of the Governance Committee, our Board annually determines the independence of each of our directors in connection with the nomination process. Further, in connection with the appointment of any new director to the Board during the year, our Board makes the same determination. In making its recommendation to the Board, the Governance Committee, with assistance from the Company’s Corporate Secretary, evaluates responses to a questionnaire completed by each director regarding relationships and possible conflicts of interest between such director, the Company, management, the independent registered public accounting firm, and the internal audit firm. In its review of director independence, the Governance Committee considers the commercial, industrial, banking, consulting, legal, accounting, charitable, and familial relationships any director may have with the Company, management, the independent registered public accounting firm, and the internal auditor.

Our Board has affirmatively determined that all current directors (other than Mr. Krcmarov) have no material relationship with the Company and are independent according to the NYSE listing standards. The Board has determined that each member of the Audit, Compensation, and Governance Committees has no material relationship with the Company and they each satisfy the independence criteria (including the enhanced qualifications with respect to members of the Audit Committee and Compensation Committee) set forth in the applicable NYSE listing standards and SEC rules. In addition, the Board has determined that each of Mr. Ralbovsky, Mr. Stanley, and Ms. Satre qualify as “Audit Committee Financial Experts,” as such term is defined by the rules of the SEC.

Directors are expected to immediately inform the Board of any material change in their circumstances or relationships that may impact their independence.

Compensation Committee Procedures

The Compensation Committee has the sole authority to set compensation for our executive officers, including annual compensation amounts and Short-term Incentive Plan and Long-term Incentive Plan criteria, evaluate the performance of our executive officers, and make awards to our executive officers under our stock incentive plans. The Compensation Committee also reviews and approves any proposed plan or arrangement providing for incentive, retirement or other compensation to our executive officers and oversees our assessment of whether our compensation practices are likely to expose the Company to material risks. In addition, the Compensation Committee annually recommends to the Board the slate of officers for the Company, periodically reviews the functions of our officers, and makes recommendations to the Board concerning those functions.

2024 Board Meetings and Attendance

Directors are expected to make every effort to attend the Annual Meeting, all Board meetings, and the meetings of the committees on which they serve. During 2024, there were nine meetings of the Board. With the exception of Ms. Satre who joined the Board in October 2024 and Mr. Krcmarov who joined the Board in November 2024, each director attended 100% of the Board meetings and the committee meetings in which they are a member. With the exception of Ms. Satre and Mr. Krcmarov, all members of the Board attended last year’s Annual Meeting of Shareholders, which was held in May 2024.

Director Orientation and Continuing Education

New directors typically undergo a comprehensive orientation program that introduces them to the Company, including our business operations, strategy, financial position, key members of management and governance structure. Directors also are encouraged to enroll in director education programs. Directors have contact with leaders throughout the organization and visit our mine sites, where they tour the facilities and interact directly with the personnel responsible for our day-to-day operations. These activities collectively help to ensure that new directors become, and existing directors remain, knowledgeable about the most important issues affecting our Company and our business.

Board and Committee Self-Evaluation Process

Our Board recognizes that a thorough, constructive evaluation process enhances the Board’s effectiveness and is an essential element of good corporate governance. Accordingly, every year, our Board and each committee of the Board conducts a self-evaluation of its performance and effectiveness. The Governance Committee oversees the annual self-evaluation process on behalf of the Board. The evaluations cover the following topics:

• |  | Board and committee composition, including skills, background, and experience;

• |  | review of key areas of focus for the Board and committees, and effectiveness in overseeing those responsibilities;

• |  | satisfaction of director performance, including that of the Board Chair;

• |  | Board and committee information needs, and quality of materials presented;

• |  | areas where the Board should increase its focus;

• |  | satisfaction with the Board and committee schedules, agendas, time allocated for topics and encouragement of open communication and discussion;

• |  | access to management, experts, and internal and external resources;

• |  | oversight of financial reporting process and internal control procedures;

• |  | ethics and compliance;

• |  | Company’s strategic direction and annual operating plan;

• |  | succession planning;

• |  | selection and evaluation process of Board candidates; and

• |  | understanding risks.

Evaluation Process

|  | INFORMATION GATHERING Our self-evaluation process is conducted on an anonymous basis, using our board portal. We have found by using an anonymous evaluation process, the Board and committee members have a level of comfort in being able to critique the Board and/or the committees.
|  | ANNUAL BOARD AND COMMITTEE EVALUATIONS The Board and each committee conduct annual self-evaluations through the use of electronic questionnaires in the board portal that cover the topics discussed on the previous page.
|  | SUMMARY OF EVALUATIONS Hecla’s Corporate Secretary uses our board portal to generate a summarized report of our directors’ anonymous responses to the electronic questionnaires and submits the report to the appropriate chair of each committee of the Board for review before the next quarterly Board and/or committee meeting.
|  | BOARD AND COMMITTEE REVIEW Using the summaries of the self-evaluations as guides, our chair of the Governance Committee reviews the results of the Board evaluation, and each committee chair reviews the results of each committee evaluation. The self-evaluations and summaries are shared and discussed with the full Board and each committee.

PROPOSAL 1

Election Of Class III Directors

In accordance with our Restated Certificate of Incorporation, the Board is divided into three classes. The terms of office of the directors in each class expire at separate times. There are three Class III directors whose terms will expire at the Annual Meeting: Charles B. Stanley, Alice Wong, and Jill Satre.

At a meeting held by the Governance Committee in February 2025, the committee determined that Mr. Stanley, Ms. Wong, and Ms. Satre were qualified candidates to stand for reelection at the Annual Meeting. The Board designated each as nominees for election as directors of the Company, each for a three-year term expiring in 2028.

Ms. Satre, who was appointed to the Board, has 22 years of public accounting experience. She is currently the Vice President of Internal Audit and Corporate Compliance at TC Energy Corporation, where she had led their Sarbanes Oxley compliance program and she is an active participant in their quarterly Public Disclosure Committee. She is an active Chartered Professional Accountant in Canada (Alberta) and has extensive experience with US GAAP. Ms. Satre also has over 10 years’ experience conducting or overseeing financial audits, reviewing Forms 10-Q and 10-K and other SEC reporting requirements, as well as over 12 years of experience advising companies on financial process and controls, including internal control over financial reporting. The Governance Committee and Board determined that Ms. Satre was independent under the NYSE listing standards, and appointed Ms. Satre to serve on the Audit Committee.

In November 2024, the size of the Board was increased from seven persons to eight persons, and upon recommendation of the Governance Committee, the Board appointed Rob Krcmarov as a Class I director (standing for election in 2026). Mr. Krcmarov was also appointed as President and CEO in November 2024. Prior to joining Hecla, Mr. Krcmarov worked in various leadership roles at Barrick Gold Corporation beginning in 2001, including serving on the executive leadership team for 13 years. His most recent role was as Executive Vice President of Exploration and Growth. His international experience spans many countries on five continents. Mr. Krcmarov has over three decades of industry experience.

It is intended that the proxies solicited hereby from our shareholders that do not provide voting instructions will be voted FOR the election of Charles B. Stanley, Alice Wong, and Jill Satre. If Mr. Stanley, Ms. Wong, or Ms. Satre becomes unable or is unwilling to accept election, the Board will either reduce the number of directors to be elected or select substitute nominees submitted by the Governance Committee. If substitute nominees are selected, proxies that do not provide voting instructions will be voted in favor of such nominees.

Biographical Information

Set forth below is biographical information for the director nominees, including the key qualifications, experience, attributes, and skills that led our Board to the conclusion that such nominees should serve as a director. There are no family relationships among any of our directors or executive officers.

Our Board includes individuals with strong backgrounds in senior leadership and management, legal, geology, accounting, finance, and company and industry knowledge, and we believe that, as a group, they work effectively together in overseeing our business.

Compensation of Non-Management

Directors

The Compensation Committee (“committee”) of the Board is responsible for recommending to the independent members of the Board the form and amount of compensation for our non-management directors. The independent members of the Board consider the committee’s recommendation and make the final determination of non-management director compensation.

Compensation for non-management directors is designed to reflect current market trends and developments with respect to compensation of Board members. It consists of a combination of cash retainers and an equity award.

Compensation Consultant and Peer Group Benchmarking

In 2024, the committee did not retain an independent compensation consultant to review director compensation. In 2024, the Company’s human resources department analyzed our non-management director compensation against our peer group. The human resources department recommended no changes to the non-management director compensation.

Components of Non-Management Director Compensation

Compensation Element |  | Current Value

Annual Board Chair Retainer |  |  | $ | 180,000 |

Annual Equity Grant (dollar equivalent) |  |  | $ | 125,000 |

Annual cash retainers are paid in quarterly installments. Other than annual cash retainers and equity, no other attendance fees are paid to the non-management directors.

Equity Compensation

We maintain the Amended and Restated Hecla Mining Company Stock Plan for Nonemployee Directors (the “Director Stock Plan” or the “plan”). The plan is currently scheduled to terminate on May 15, 2027, and is subject to termination by the Board at any time. Pursuant to the plan, before September 30 of each year, each non-management director is credited with a number of shares determined by dividing the annual equity retainer payable to each non-management director for service on the Board for the following year by the average closing price for Hecla’s common stock on the NYSE for the prior calendar year (the “Stock Retainer”). A minimum of 25% of the annual Equity Grant under the Director Stock Plan is contributed to a grantor trust established by the Company. Each director may elect, prior to the first day of the applicable year, to have a greater percentage contributed to the grantor trust for that year. The remaining portion of the Equity Grant will be transferred to the non-management director as soon as practicable. Non-management directors joining the Board after September 30 of any year will be credited with a pro rata grant of shares when they join the Board.

The shares held in the grantor trust are subject to the claims of our creditors until delivered under the terms of the Director Stock Plan. Delivery of the shares from the trust occurs upon the earliest of: (i) death or disability; (ii) retirement from the Board; (iii) a cessation of

the director’s service for any other reason; (iv) a change in control of the Company (as defined in the Director Stock Plan); or (v) a time elected by the director, except shares must be held in the trust for at least two years prior to delivery. As of December 31, 2024, there were 2,039,789 shares remaining available for issuance under the Director Stock Plan.

With the exception of Ms. Boggs, whose director and Interim President and CEO compensation are reported in the Summary Compensation Table on page 72, the following chart summarizes the annual cash and equity compensation for our non-management directors during 2024.

(3) | The amounts in the column headed “Stock Retainer” represent the aggregate grant date fair value computed in accordance with Financial Accounting Standards Board ASC Topic 718. For a description of the assumptions used in valuing the awards please see Note 12 to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. The Stock Retainer column represents the aggregate grant date fair value of the stock granted to each non-management director under the Director Stock Plan in 2024 as computed in accordance with ASC Topic 718. For each director, except Ms. Satre (see footnote 4) the number of common shares granted was determined by dividing $125,000 by the average closing price for Hecla’s common stock on the NYSE for the prior calendar year ($5.148) ($125,000 ÷ $5.148 = 24,281). Except for Ms. Satre, on June 24, 2024, each non-management director received 24,281 shares of our common stock under the terms of the Director Stock Plan. Based on our closing stock price on the NYSE on the date of grant of June 24, 2024 ($5.05), the grant date fair value for each grant of 24,281 shares was $122,619. The actual value realized by a non-management director will depend on the market value of our common stock on the date the underlying stock is sold.

(4) | Ms. Satre was appointed to the Board on October 16, 2024. Under the Director Stock Plan, any nonemployee director appointed or elected as a director shall receive a prorated portion of the Stock Retainer. Ms. Satre was granted 4,700 shares of common stock on October 16, 2024. Based on our closing stock price on the NYSE on the date of grant of October 16, 2024 ($6.78), the grant date fair value of 4,700 shares was $31,866.

(5) | The Company made a matching contribution under its charitable matching gift program on the behalf of Mr. Johnson.

Other

The Company covers directors under its overall director and officer liability insurance policies, as well as reimbursing them for travel, lodging, and meal expenses incurred in connection with their attendance at Board and committee meetings, meetings of shareholders, and for traveling to visit our operations or other Company business. Directors are eligible, on the same basis as Company employees, to participate in the Company’s matching gift program, pursuant to which the Hecla Charitable Foundation matches contributions made to qualifying nonprofit organizations. Beyond these items, no other compensation was paid to any non-management director.

Non-Management Director Stock Ownership Guidelines

To more closely align the Company’s independent directors’ financial interests with those of our shareholders, in June 2012, the committee and Board adopted stock ownership guidelines for our independent directors. Under these guidelines, each independent director is required to own shares of common stock (which includes shares held under the Director Stock Plan) valued at three times their annual cash retainer within five years of their appointment to the Board. In the event an independent director’s cash retainer increases, they will have three years from the date of the increase to acquire any additional shares needed to meet these guidelines.

Because of fluctuations in the Company’s stock price, in February 2016, the committee and the Board amended the stock ownership guidelines to provide a valuation methodology that consists of valuing the shares held by using the average closing price of the Company’s common stock on the NYSE for the previous calendar year. Because share prices of all companies are subject to market volatility, the Board believes that it would be unfair to require a director to buy more shares simply because Hecla’s stock price drops. In the event there is a significant decline in Hecla’s stock price that causes a director’s holdings to fall below the applicable threshold, the director will not be required to purchase additional shares to meet the threshold, but they generally may not sell or transfer any shares until the threshold has again been achieved.

As of December 31, 2024, Messrs. Stanley, Ralbovsky, and Johnson, as well as Ms. Boggs and Ms. Wong met the guidelines. Mr. Board and Ms. Satre are not yet required to meet the minimum share holdings.

Additional information regarding shares held by the non-management directors is included in the Security Ownership of Certain Beneficial Owners and Management table on page 94.

PROPOSAL 2

Ratify The Appointment Of BDO USA, P.C. As Our Independent

Registered Public Accounting Firm For 2025

The Audit Committee is solely responsible for the appointment, compensation, retention, evaluation, and termination, if necessary, of the independent registered public accounting firm retained to audit our financial statements. The Audit Committee appointed BDO USA, P.C. (“BDO”) as the independent registered public accounting firm for Hecla for the calendar year ending December 31, 2024. BDO has been retained in that capacity since 2001. The Audit Committee is aware that some may believe a long-tenured auditor poses an independence risk. To address these concerns, the Audit Committee:

• |  | reviews all non-audit services and engagements provided by BDO, specifically with regard to the impact on the firm’s independence;

• |  | conducts a quarterly assessment of BDO’s service quality, and its working relationship with our management;

• |  | conducts regular private meetings separately with each of BDO and our management;

• |  | interviews and approves the selection of BDO’s new lead engagement partner with each rotation;

• |  | at least annually, obtains and reviews a report from BDO, describing all relationships between the independent auditor and Hecla; and

• |  | reviews data relating to audit quality and performance, including the most recent Public Company Accounting Oversight Board (“PCAOB”) reports on BDO and its peer firms.

The members of the Audit Committee believe that the continued retention of BDO to serve as our independent registered public accounting firm is in the best interests of Hecla and our shareholders.

Although ratification is not required, the Board and the Audit Committee are submitting the appointment of BDO to our shareholders for ratification because we value our shareholders’ views on our independent registered public accounting firm, and as a matter of good governance practice. In the event our shareholders fail to ratify the appointment, it will be considered as a direction to the Board and to the Audit Committee to consider the appointment of a different firm. Even if the appointment is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interest of the Company and its shareholders.

Representatives of BDO are expected to be present at the Annual Meeting with the opportunity to make statements and respond to appropriate questions from shareholders present at the meeting.

Required Vote

Under the Sarbanes-Oxley Act of 2002, the Audit Committee has the sole authority to appoint the independent registered public accounting firm for the Company. However, the Board feels that it is important for the shareholders to ratify the selection of BDO USA, P.C. This proposal requires the affirmative vote of a majority of votes cast at the Annual Meeting, whether in person or by proxy. See What Votes are Required for the Proposals on page 102.

You may vote “FOR,” “AGAINST,” or “ABSTAIN” on the proposal to ratify the appointment of BDO USA, P.C. as our independent registered public accounting firm for 2025.

|  |  |  |  |  | The Audit Committee and Board recommend shareholders vote “FOR” ratifying the appointment of BDO USA, P.C. as our independent registered public accounting firm for 2025.

Pre-Approval Process

The Audit Committee is responsible for reviewing and, if appropriate, pre-approving all audit, audit-related and non-audit services to be performed by our independent registered public accounting firm. The Audit Committee charter authorizes the Audit Committee to establish a policy and related procedures regarding the pre-approval of audit, audit-related and non-audit services to be performed by our independent registered public accounting firm.

The Audit Committee has delegated its pre-approval authority to the Chair of the Audit Committee, who is authorized to pre-approve services to be performed by our independent registered public accounting firm and the compensation to be paid for such services until the next regularly scheduled meeting of the Audit Committee, provided that in such case, the Chair shall provide a report to the Audit Committee at its next regularly scheduled meeting of any services and compensation approved by the Chair pursuant to the delegated authority. On a periodic basis, management reports to the Audit Committee the actual spending for projects and services compared to the approved amounts.

PROPOSAL 3

Approval, On An Advisory Basis, Of Our Named

Executive Officer Compensation

Our Board seeks your vote to approve, on an advisory, non-binding basis, the compensation paid to our named executive officers (“NEOs”) for 2024 as set forth under the heading Compensation Discussion and Analysis (CD&A) on page 44, and related material. This proposal, commonly known as a “Say-on-Pay” proposal, gives our shareholders the opportunity to express their views on our NEOs’ compensation as a whole. The Board believes that our current NEO compensation program is right for the Company and our shareholders. The program is designed to attract, retain, and motivate talented individuals who possess the executive experience and the leadership skills needed by the Company to maintain and increase shareholder value. We seek to provide NEO compensation that is competitive with that provided by companies in our peer group within the mining industry. We also seek to provide both short- and long-term financial incentives to our NEOs that reward them for superior performance and achieving financial results and strategic objectives that are expected to contribute to increased long-term shareholder value.

Underlying these incentives is a strong philosophy of “pay-for-performance” that forms the foundation of decisions regarding the compensation of our NEOs. This compensation philosophy, which has been consistent over many years, is designed to align the interests of our NEOs with the interests of our shareholders and is central to our ability to attract, retain and motivate executive leaders to guide the Company through market challenges over the long term.

The primary methods we use to align the interests of our NEOs with our shareholders include:

• |  | placing a vast majority (77.1%) of our non-interim CEO’s total compensation at-risk;

• |  | targeting total direct compensation of our NEOs at approximately the 50th percentile of peer compensation;

• |  | striking the right balance between short- and long-term compensation; and

• |  | selecting appropriate performance metrics, including market-based measures such as total shareholder return, annual financial and operational goals (such as production, cash flow, exploration, and safety).

Some highlights of our 2024 NEO compensation program include:

• |  | our 2024 Short-term Incentive Plan aligns 2024 payments to actual performance on pre-established targets, effectively linking NEO pay to the Company’s financial performance; and

• |  | our 2024 Performance-based Stock Units (“PSUs”) are tied to relative total shareholder return (“TSR”) over three years, effectively linking NEO pay to the Company’s long-term performance.

In 2024, of our shareholders who voted, 69% voted in favor of our NEO compensation program. This was lower than the Say-on-Pay vote support of approximately 97% in 2023. The Compensation Committee and our full Board took the Say-on-Pay vote outcome seriously and, as a result, we made changes, including to our short- and long-term incentive compensation program. In advance of our 2025 Annual Meeting, we conducted a shareholder engagement campaign to speak directly with some of our shareholders to discuss the changes we made. Our shareholder engagement campaign and related changes to our NEO compensation program are described in more detail in the section entitled “Shareholder Engagement” starting on page 55.

In considering how to vote on this proposal, we urge you to review the relevant disclosures in this Proxy Statement, particularly the CD&A section, which contains detailed information about our NEO compensation program. We have held our “Say-on-Pay” advisory vote annually since 2011. The next required shareholder vote to recommend the frequency of such votes is expected to occur in 2029.

The Board and the Compensation Committee value the opinions of our shareholders and to the extent there is any significant vote against the NEO compensation as disclosed in this Proxy Statement, the Compensation Committee will carefully review and consider the voting results when evaluating our NEO compensation program.

##### Table of Contents

|  |  |  | 2025 Proxy Statement | 43

We are asking shareholders to approve the following resolution at the Annual Meeting:

“RESOLVED, that the compensation paid to the Company’s NEOs, as disclosed pursuant to Item 402 of Regulation S-K, described in the CD&A, Summary Compensation Table for 2024, and the related compensation tables and narrative in the Proxy Statement for the Company’s 2025 Annual Shareholders’ Meeting, is hereby APPROVED.”

Required Vote

The advisory vote on NEO compensation will require the affirmative vote of a majority of votes cast at the Annual Meeting, whether in person or by proxy. See What Votes are Required for the Proposals on page 102.

You may vote “FOR,” “AGAINST,” or “ABSTAIN” on the proposal to approve the compensation of our NEOs.

|  |  |  |  |  | The Board recommends that you vote “FOR” approval of the compensation of our NEOs.

Executive Summary

We are the largest primary silver producer in the United States and Canada – and the oldest NYSE-listed precious metals mining company in North America (listed for 60 years). We produce more than 45% of all silver in the United States, and have operating mines in Alaska (Greens Creek), Idaho (Lucky Friday), Quebec, Canada (Casa Berardi), and the Yukon Territory, Canada (Keno Hill). We also own a number of exploration and pre-development properties in world-class silver and gold mining districts throughout North America.

We delivered strong operation performance in 2024, meeting our consolidated silver production and cost guidance, while exceeding gold production targets. Strategically, our exploration program successfully maintained our silver reserve position, which, at the end of 2024, was the second highest in the Company’s history. We had particularly strong operating results at Greens Creek. Greens Creek and Lucky Friday generated a total of $228 million of free cash flow(3) during the year. Our robust cash generation and associated EBITDA enabled us to significantly improve our net leverage ratio from 2.7x to 1.6x, while simultaneously investing $215 million in total capital across our portfolio. Lucky Friday maintained its best safety AIFR of 1.4 for a full production year while delivering the highest tons mined and milled, and the most zinc produced in its 80-year history, as well as the highest silver production since 2000.

In 2024, we produced 16.2 million ounces of silver, 141,923 ounces of gold, 66,308 tons of zinc, and 52,515 tons of lead. We generated $218.3 million in cash provided by operating activities, with $27.3 million in exploration and pre-development and $43.3 million in ramp-up suspension costs.

We also had sales of $929.9 million and $26.9 million in cash and cash equivalents on our balance sheet. We revised our common stock dividend policy to eliminate the silver-linked component.

After considering overall Company performance in 2024, the committee determined the company achieved 92% of the STIP target. However, due to production shortfalls, higher than budgeted costs of production, and permitting issues at Keno Hill and Casa Berardi, the committee used its negative discretion and reduced the award to 85% of target. The committee assessed 2022-2024 LTIP performance to be 84% of target. Lastly, because our three-year TSR ranking did not achieve the 50th percentile of our peer group, PSUs awarded to our NEOs in 2022 resulted in a $0 per unit payout.

As a result of last year’s Say-on-Pay results and feedback we received in our shareholder engagement program, we terminated or modified several compensation plans as described below. See Shareholder Engagement on page 55.

Key Operating and Significant Financial Results

The mining business requires long-term planning and implementation of operating strategies over several years to deliver successful operating and financial results. Accordingly, in the table below and summary that follows, we set forth our key operating and financial results for years 2024, 2023 and 2022.

|  |  |  | 2025 Proxy Statement | 47

Our overall operating and financial results are more fully described in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K filed with the SEC on February 13, 2025. Some of our key achievements during 2024 were as follows:

Operational:

• |  | silver reserves of 240 million ounces, second highest in the Company’s 134-year history;

• |  | gold reserves of 2.2 million ounces;

• |  | produced 16.2 million ounces of silver, Hecla’s second highest, and 141,923 ounces of gold;

• |  | zinc production of 66,308 tons and lead production of 52,515 tons;

• |  | our Lucky Friday mine mitigated the damages to the #2 Shaft and restarted production in January 2024;

• |  | Keno Hill produced 2.8 million ounces of silver, meeting guidance of 2.7 – 3.0 million ounces;

• |  | copper became a payable metal for Greens Creek, resulting in a new revenue stream that generated $0.4 million copper sales; and

• |  | AIFR outperformed national average of mining companies by 6%.

Financial:

• |  | achieved record sales of $929.9 million;

• |  | generated net income applicable to common shareholders of $35.3 million and returned $24.9 million to our common shareholders through dividend payments;

• |  | made capital expenditures of approximately $214.5 million, including $47.8 million at Greens Creek, $49.6 million at Lucky Friday, $60.7 million at Casa Berardi, and $54.9 million at Keno Hill;

• |  | spent $27.3 million on exploration and pre-development activities; and

• |  | raised $58.4 million in common stock sales under our ATM program with proceeds used to make repayments on our outstanding revolving credit facility balance.

Governance:

• |  | added three new directors in 2024; and

• |  | our Board now consists of 38% women.

Benchmarking and Competitive Analyses

We have adopted a pay-for-performance philosophy that incentivizes performance by targeting base salaries below the median of our peer group but targeting incentives above the peer median. The total direct compensation of our NEOs is targeted at approximately the 50th percentile. The process of setting targeted compensation includes consideration of a NEO’s skills, experience, knowledge, and reputation in the industry, as well as Company needs.

Central to the pay review process is the selection of a relevant peer group. Because we operate in a global business that is dominated by Canadian companies, our peer group includes only two U.S. companies. In addition, we have a corporate office in Vancouver, British Columbia, where two of our executives and several other employees work. The committee reviews and determines the composition of our peer group on an annual basis. In May 2024, the committee approved the same peer group as used in the previous year.

##### Table of Contents

48 | 2025 Proxy Statement |  |  |  |

In 2024, our peer group was made up of the following 13 companies, which is the same peer group used for NEO compensation in 2023:

Company |  | Annual Revenue(1) ($US millions) |  |  | Market Cap(1) ($US millions) |  |  | Total Assets(1) ($US millions) |  |  | Corporate Location |
Alamos Gold Inc. (NYSE: AGI) |  |  | 1,347 |  |  |  | 7,744 |  |  |  | 5,336 |  |  |  | Canada |

New Gold Inc. (NYSE: NGD) |  |  | 925 |  |  |  | 1,973 |  |  |  | 2,004 |  |  |  | Canada |
NOVAGOLD Resources Inc. (NYSE: NG) |  |  | 0 |  |  |  | 1,231 |  |  |  | 110 |  |  |  | Canada |
Pan American Silver Corporation (Nasdaq: PAAS) |  |  | 2,819 |  |  |  | 7,336 |  |  |  | 7,203 |  |  |  | Canada |
Royal Gold, Inc. (Nasdaq: RGLD) |  |  | 719 |  |  |  | 8,670 |  |  |  | 3,392 |  |  |  | United States |
SSR Mining Inc. (Nasdaq: SSRM) |  |  | 996 |  |  |  | 1,412 |  |  |  | 5,189 |  |  |  | Canada |
Torex Gold Resources Inc. (OTC: TORXF) |  |  | 814 |  |  |  | 1,692 |  |  |  | 1,487 |  |  |  | Canada |
Median |  |  | 1,054 |  |  |  | 2,284 |  |  |  | 3,392 |  |  |  |  |
Hecla Mining Company (NYSE: HL) |  |  | 930 |  |  |  | 3,102 |  |  |  | 2,981 |  |  |  | United States |

(1) | In $US millions as of year-end 2024.

The peer group is composed entirely of publicly held companies, all of which are engaged in the business of mining precious metals, with revenue, market capitalization and total assets within a reasonable range of Hecla’s. We believe these peer companies are appropriate because they are in the same industry, compete with us for executive talent, have executives in positions similar to ours, and are considered by the committee to be comparable to Hecla.

Over the years during our shareholder engagement discussions, some of our largest shareholders informed us that, compared to peer groups selected by proxy advisory firms, they consider the peer group chosen by us to be more relevant and appropriate for compensation and performance benchmarking purposes. The peer group selected last year by Glass Lewis included 11 of our 13 selected peers. The peer group selected by Institutional Shareholder Services (ISS) included only three of our 13 selected peers. The rest of the peer group selected by ISS contained U.S.-based companies in the industrial and specialty chemicals, plastics, coatings, nickel and cobalt-based alloys, steel products and other industries – companies and industries whose market fundamentals are materially different from that of the precious metals mining industry. We understand that ISS’s internal policies prohibit its inclusion of Canadian companies (which account for 11 of our peers) and require that Hecla be compared to companies having only similar revenue instead of similar market capitalization or total assets. We believe a fair compensation peer group, in terms of both industry profile and size, should not be selected for Hecla without including Canadian mining companies.

The committee reviewed an analysis of executive compensation levels at the 25th, median, and 75th percentiles of the peer group for positions comparable to those held by each of our NEOs. The committee also compared the target total cash compensation (base salary plus target STIP) for each of the NEOs against these benchmarks. For retention and competitive considerations, in comparison to the peer group data applicable to each NEO’s position, we generally target each NEO’s total direct compensation at the median level and deliver compensation above or below these levels when warranted by individual performance. In 2024, total direct compensation for our NEOs was targeted approximately at the median of the peer group.

In 2024, the committee approved a separate peer group to be used specifically with regard to TSR, which is the same as our 2023 TSR peer group, for purposes of our PSUs, discussed below, which consisted of the following companies/funds:

Alamos Gold Inc. (NYSE: AGI) |  | Coeur Mining, Inc. (NYSE: CDE) |  | New Gold Inc. (NYSE: NGD)
B2Gold Corp. (NYSE: BTG) |  | First Majestic Silver Corp. (NYSE: AG) |  | Centerra Gold Inc. (NYSE: CGAU)
IAMGOLD Corporation (NYSE: IAG) |  | Van Eck Gold Miners ETF (ARCX: GDX) |  | Pan American Silver Corp. (Nasdaq: PAAS)
SSR Mining Inc. (Nasdaq: SSRM) |  | Van Eck Junior Gold Miners ETF (ARCX: GDXJ) |  | Eldorado Gold Corporation (NYSE: EGO)
Equinox Gold Corp. (NYSE: EQX) |  | Oceana Gold Corp. (OTCM: OCANF) |  | iShares Silver Trust (ARCX: SLV)
Fresnillo PLC (OTC: FNLPF) |  | Hochschild Mining plc (OTCM: HCHDF) |  | SPDR Gold Shares (ARCX: GLD)
Torex Gold Resources Inc. (OTC: TORXF) |  | Fortuna Silver Mines Inc. (NYSE: FSM) |  |

Our executive compensation peer group is different from our TSR peer group. When setting executive compensation, we use a peer group made up of those with whom we compete for talent. For the TSR peer group, we use a set of companies and ETFs for which we compete for investment dollars.

The Compensation Committee Process and the Role of Management and Human Resources Department

Role of the Committee. The committee, consisting entirely of independent members (Stanley, Johnson, Wong, and Boggs), has primary responsibility for executive compensation decisions. During her tenure as ICEO, Ms. Boggs did not serve on the committee. She was reappointed to the committee after finishing her role of ICEO. The committee carries out its responsibilities under a charter approved by the Board. The committee has the authority to approve all executive compensation, including our CEO’s (but not that of our independent directors, which is decided by the full Board). In 2024, management only received assistance from an independent executive compensation consultant to review and prepare the pay versus performance section of our proxy statement. The committee evaluated the Company’s compensation arrangements to determine if their provisions and operation created undesired or unintentional risks of a material nature. The committee found that our compensation policies and practices do not create inappropriate or unintended material risk to the Company as a whole. See Compensation Risk Analysis on page 69. Additionally, in 2024, the committee implemented compensation arrangements to support a CEO transition.

Role of Human Resources Department. In 2024, the committee determined the Company’s human resources department had the capacity to review and evaluate our executive compensation program and develop comparisons with the programs and NEO compensation levels of our peer companies. In 2024, the human resources department performed the following services:

• |  | evaluated the competitiveness of the total direct compensation package provided to Hecla’s executive officers; and specifically, compared Hecla’s current executive officer compensation with compensation provided to executives in similar roles at comparable peer group companies listed in the table below;

• |  | reviewed updated information regarding Hecla’s executive compensation program and the positions to be benchmarked, including organization charts, position descriptions, current total compensation, and other relevant data;

• |  | reviewed last year’s peer group to determine if the included companies continue to be appropriate and if any additional companies should be considered for inclusion, or removed from the peer group due to a merger, acquisition, etc.;

• |  | collected and analyzed compensation data from the most recent proxy filings of the peer group and summarized the market pay data and compared Hecla’s executive compensation levels to the peer group proxies;

• |  | analyzed the year-over-year change in compensation levels for Hecla compared to each market data source;

• |  | analyzed Hecla’s long-term incentive and equity practices compared to peers;

• |  | prepared a report to the committee summarizing the methodology used and findings; and

• |  | assisted the committee in meeting its obligation to issue a Compensation Committee Report recommending inclusion of the CD&A in the Proxy Statement.

In June 2024, Hecla’s human resources department presented its competitive analysis findings and recommendations to the committee. The competitive analysis provided detailed comparative data for each executive officer position and assessed each component of pay, including base salary, short-term incentives, and total target compensation, as well as the mix of compensation among these pay elements across the Company’s peer group. The committee compared this information to the executive’s compensation by similarity of position. The committee also reviewed the Company’s performance and carefully evaluated each executive’s performance during the year against established goals, leadership qualities, operational performance, business responsibilities, current compensation arrangements and long-term potential.

Role of Management. The committee considers input from the CEO in making determinations regarding our executive compensation program and the individual compensation of each NEO (other than the CEO). As part of our annual review process, the CEO reviews the performance of the other NEOs and their contribution to the overall performance of the Company. Approximately mid-year, the CEO presents recommendations to the committee regarding base salary adjustments, target STIP awards, and stock-based grants, based on a thorough analysis of relevant market compensation data comparing Hecla with an applicable peer group within the mining industry. The CEO and SVP-CAO also make recommendations to the committee regarding the Company’s short-term quantitative goals, and long-term goals for the NEOs (other than the CEO), as well as recommendations regarding the participation in the Company’s stock-based compensation plans and amendments to the plans, as necessary.

Compensation Philosophy and Objectives

Management and the Board recognize the mining industry is cyclical, influenced by market factors, and can include wide swings in the prices for base and precious metals, which are beyond management’s control, and which can significantly influence our profitability and share price. Further, we operate in a competitive and challenging industry, and the supply of mining executives is extremely limited, particularly in the United States. As a result, having a viable compensation strategy is critical to our success.

We expect top-level performance from our executive management team during downturns in our industry and during periods of Company expansion. Accordingly, the criteria the committee has established for our performance-based awards have sometimes been particularly challenging to achieve. Nevertheless, even in years for which we have incurred a net loss, we have often performed better than most of our industry peers in key respects (e.g., reserves and resources replacement).

Our compensation philosophy is to pay our NEOs competitive levels of compensation that best reflect their individual responsibilities and contributions to the Company, while providing incentives to achieve our business and financial objectives. While comparisons to compensation levels at companies in our peer group are helpful in assessing the overall competitiveness of our compensation program, we believe our executive compensation program must also be internally consistent and equitable to achieve our corporate objectives.

The pay-for-performance philosophy of our executive compensation programs described in this Proxy Statement plays a significant role in our ability to produce strong operating, exploration, strategic, and financial results. It enables us to attract and retain a highly experienced and successful team to manage our business. The programs strongly support our business objectives and are aligned with the value provided to our shareholders. Further, as an executive’s level of responsibility within our organization increases, so does the percentage of total compensation we link to performance – through the short- and long-term incentive programs, as well as share price performance.

In setting policies and practices regarding compensation, the guiding philosophy of the committee is to:

• |  | have compensation that is primarily at-risk and based on strategic objectives and tactical activities;

• |  | acquire, retain, and motivate talented executives; and

• |  | total direct compensation is set within a competitive range of our peer group to ensure that it is appropriate and is aligned with the level of position, experience, skills, and performance of the executive.

The committee believes a mix of both cash and equity incentives is appropriate, as cash incentives reward executives for achieving both short- and long-term goals, while equity incentives align the interests of our executives with those of our shareholders. In determining the amount of the cash and equity incentives, the committee considers each officer’s total compensation on both a short- and long-term basis to assess the retention and incentive value of their overall compensation.

We also maintain (or avoid) the following pay practices that we believe enhance our pay-for-performance philosophy and further align our NEOs’ interests with those of our shareholders:

Pay-for-Performance – Best Practices

• |  | the compensation of identified peer companies based on industry and size criteria is considered to ensure that pay levels and program design for the NEOs are appropriate and competitive;

• |  | incentive awards are heavily dependent upon our stock performance and are measured against objective financial metrics;

• |  | the majority of total direct compensation for executives is performance-based as well as equity-based to align executives’ rewards with sustained shareholder value;

• |  | total direct compensation is set within a competitive range of our peer group to ensure it is appropriate and aligned with the level of position, experience, skills, and performance of the executive;

• |  | actual realized total direct compensation and pay positioning are designed to fluctuate with, and be commensurate with, actual annual and long-term performance, recognizing Company-wide and individual results;

• |  | we grant PSUs that include a relative TSR metric within our selected peer group;

• |  | robust stock ownership requirements for our executive officers and directors;

• |  | our change in control agreements contain a double trigger provision and upon a change of control there is no excise tax gross up;

• |  | time-based equity awards generally vest over a three-year period to promote retention;

• |  | our Insider Trading Policy provides that directors and officers are prohibited from hedging or pledging any securities of the Company;

• |  | each of the Company’s incentive plans (STIP, LTIP, KEDCP, and 2010 Stock Plan) have clawback provisions;

• |  | our NEOs, including our CEO, generally must remain employed with the Company through the payment date of their short- and long- term awards, or the awards are forfeited, except in limited cases upon qualifying terminations of employment;

• |  | our Insider Trading Policy prohibits all directors, executive officers, and certain other employees from purchasing or selling any Company securities three weeks before through two days after the public release of any of our periodic results, or at any other time during the year while in possession of material non-public information about the Company;

• |  | compensation programs designed to discourage unnecessary or imprudent risk taking;

• |  | caps on performance-based cash and equity incentive compensation; and

• |  | annual review and approval of executive compensation strategy.

Compensation Program – Best Practices

• |  | we conduct an annual shareholder engagement program and use that input when considering our program decisions and pay practices;

• |  | we disclose our corporate performance goals and achievements relative to these goals;

• |  | we devote considerable time to management succession planning and leadership development efforts;

• |  | we have a clawback policy that enables the Board to recoup compensation in the event of a financial restatement or misconduct, which mitigates compensation-related risk and complies with applicable SEC rules and NYSE listing standards. See Clawback Policy on page 66 for additional information;

• |  | we maintain robust stock ownership guidelines for executive officers and non-management directors. See Non-Management Director Stock Ownership Guidelines on page 38, and Stock Ownership Guidelines for NEOs on page 66 for additional information;

• |  | we prohibit our executive officers and all non-management directors, from engaging in any form of hedging transaction involving Hecla securities, holding Hecla securities in margin accounts and pledging stock as collateral for loans in a manner that could create compensation-related risk for the Company; and

• |  | we do not provide excise tax gross ups.

Targeted Compensation

Our executive compensation program – composed primarily of base salary, short and long-term incentives, and equity awards – is intended to align the interests of our NEOs with the long-term interests of our shareholders. The program is designed to accomplish this by rewarding performance that results in an increase in the value of our shareholders’ investment in Hecla. We believe the proportion of at-risk, performance-based compensation should comprise a significant portion of executive pay.

2024 Target Compensation Structure

The following table lists total 2024 target compensation for the NEOs.

Given the timing of Mr. Krcmarov’s appointment, these awards were not granted in 2024.

(2) | In connection with Mr. Sienko’s promotion in August 2024 and our peer group analysis, his salary was increased from $330,000 to $345,000, and his STIP target was increased from 70% to 100%, or $231,000 to $345,000, respectively.

(3) | Ms. Boggs served as the ICEO from May 22, 2024 to November 7, 2024.

Changes in Compensation Plan Design for 2025 and Results for 2024

Summary

Shareholder Engagement. In 2024, of our shareholders who voted, 69% voted in favor of our NEO compensation program. This was lower than the Say-on-Pay vote support of approximately 97% in 2023. While we have a history of strong engagement with our shareholders, in order to better understand this vote result and solicit shareholder feedback, we undertook a shareholder engagement campaign following our 2024 Annual Meeting. We contacted institutional shareholders representing approximately 239.7 million shares to, among other things, discuss our executive compensation program, policies, and practices, solicit feedback, and ensure that we had insight into the issues that were most important to our shareholders so that we could better understand their perspectives. Our offer to engage was accepted by one institutional shareholder representing approximately 2.8 million shares and one proxy advisory firm. These discussions included our SVP–CAO, SVP–GC, VP–CDS, VP–Investor Relations and Treasurer, and Assistant Secretary.

During these meetings, we received valuable feedback on our executive compensation program. We discussed the reasons for opposition to, or support of, our Say-on-Pay resolution for 2023 NEO compensation. After our 2024 Annual Meeting, we amended the plans described in the table below. Prior to meeting with the one shareholder, and one proxy advisory firm, the feedback we received was that our amendments to our compensation plans were good.

Area of Focus |  | What we Heard |  | How We Responded
LTIP |  | Lacked pre-established, objective, and formulaic performance goals. |  | Starting with 2024, we discontinued the LTIP and allocated long-term incentives to RSUs and PSUs.
STIP |  | Contained non-measurable qualitative goals and provided the Compensation Committee positive discretion to adjust formulaic payouts. |  | Starting with 2024, we eliminated the qualitative and positive discretionary components. The STIP is now based entirely on quantitative performance metrics (and negative discretion where appropriate).
Change-in-Control and Severance |  | Excessive cash separation benefits under certain scenarios for the President and CEO. |  | Our former President and CEO was eligible for a severance benefit under his Change-in-Control Agreement that exceeded three times his annual cash compensation. Starting with our new CEO, the benefit is now two times his annual cash compensation.

In addition, as part of our ongoing evaluation of best practices, in 2024 we froze our Retirement Plan, which is a defined benefit pension plan, to eliminate any additional participants, including our new President and CEO, and we froze our KEDCP to eliminate future deferrals under the KEDCP.

CEO Transition. In 2024, our actions included implementing compensation arrangements to support a CEO transition. On May 22, 2024, Phillips S. Baker, Jr., departed from his position as the Company’s then-President and CEO. Immediately following Mr. Baker’s departure, the Company appointed Catherine “Cassie” J. Boggs to serve as Interim President and CEO (“ICEO”). In connection with her role as ICEO, Ms. Boggs received a monthly salary of $106,000, payable 60% in cash ($63,600) and 40% in shares ($42,400) of the Company’s common stock. In connection with her services as ICEO, Ms. Boggs was not eligible for an annual cash bonus opportunity. The committee determined this was appropriate not only given the temporary and transitional nature of Ms. Boggs’ role and her existing meaningful financial stake in the Company, but also given that at the time she commenced her role as ICEO, nearly half of the performance period within our 2024 annual performance-based incentive program had elapsed. Given the unique nature of Ms. Bogg’s compensation, it is not included in the tables and narrative immediately below, which cover the regular NEO compensation program for non-interim CEOs. Please see the Summary Compensation Table for 2024 on page 72 for more detailed information on the economics of Ms. Boggs’ compensation for her services as our ICEO. In light of his departure from the company, Mr. Baker did not receive any RSUs or PSUs in 2024.

Following an extensive candidate search and interview process, our Board appointed Rob Krcmarov as our President and CEO effective November 7, 2024. In connection with his appointment, Mr. Krcmarov and the Company executed an offer letter (Offer Letter). Pursuant to the Offer Letter, he will receive an initial base salary of $850,000 and be eligible to participate in the Company’s STIP with a target for his position of 110% of base salary, with the opportunity to receive a higher or lower payout depending on the Company’s performance. In January 2025, Mr. Krcmarov also received $1,930,000 in RSUs vesting over three years. He will also receive $1,265,000 target PSUs (to be awarded in June 2025). Since the RSUs were not awarded until January 2025 and the PSUs will not be granted until June 2025, they are not included in the Grants of Plan-Based Awards Table for 2024. The Company also provided Mr. Krcmarov with relocation assistance and agreed to assist him with certain tax filings. These benefits were not provided until 2025 and are therefore not included in the Summary Compensation Table for 2024 on page 72. In determining Mr. Krcmarov’s compensation, the committee noted that we actively compete with other companies in seeking to attract and retain a skilled executive management team. This is particularly prevalent in our industry,

##### Table of Contents

56 | 2025 Proxy Statement |  |  |  |

where there are a number of companies intensely competing for highly qualified candidates. In determining Mr. Krcmarov’s compensation package, the committee took into account the compensation opportunities forfeited by his resignation from public company board positions he held at the time of his hire.

In connection with his appointment, the Company also entered into a Change in Control and Severance Agreement with Mr. Krcmarov. Mr. Krcmarov’s eligibility for severance payments and benefits reflects the Company’s historical severance payments and benefits structure for executive officers and is consistent with similar arrangements provided by our peers.

With respect to our other NEOs, in 2024:

• |  | the base salary for Mr. Sienko was increased by approximately 5% and his target annual bonus increased from 70% of base salary to 100%, due to his promotion to SVP–GC, and in response to our peer group analysis;

• |  | the assessment of our STIP corporate performance quantitative factors was 92% of target; however, the committee used its negative discretion and reduced the award to 85% of target;

• |  | the 2022-2024 LTIP resulted in a payout to the NEOs of $75.69 per unit compared to a target of $90 per unit, or approximately 84% of target, and was paid in common stock; and

• |  | PSU performance against the peer group achieved below threshold results due to our TSR ranking of 14th among the 20 peers in our group for the 2022-2024 period. Placing 14th among the peer companies, resulted in no award. See 2022-2024 PSU Results on page 65 for further information.

Base Salary

Design. The committee targets NEO base salaries at the approximate median among Hecla’s peer group. An individual NEO’s base salary may be set above or slightly below this range for that particular position, depending on the committee’s subjective assessment of the individual NEO’s experience, expected future contribution, retention concerns, and the recommendation of our CEO (other than for the CEO). The committee does not use a quantitative formula to determine the base salary levels of any of the NEOs. The committee reviews NEO salaries at least annually as part of its overall competitive market assessment, as previously described. Typically, the committee makes annual salary adjustments in the middle of each calendar year, effective for the 12-month period from July 1 to June 30.

Analysis and Decision. In June 2024, the committee reviewed an analysis prepared by the Company’s human resources department, but did not adjust any base salaries. In August 2024, the committee adjusted the base salary for Mr. Sienko by approximately 5% due to his promotion to SVP–GC and to better align his compensation level to the current peer group median for 2024.

The following table shows annualized base salaries for all non-interim NEOs from July 1, 2023 through December 31, 2024:

Annualized Base Salary for NEOs July 1, 2023 through December 31, 2024

NEO |  | 7/1/23 thru 6/30/24 Salary ($) |  |  | 7/1/24 thru 12/31/24 Salary ($) |

(1) | Mr. Sienko’s base salary was increased due to his promotion to SVP–GC in August 2024.

(2) | Mr. Baker departed from the company in May 2024.

Incentive Plans

STIP

Consistent with Hecla’s pay-for-performance philosophy, substantially all salaried employees, including our NEOs, are eligible to participate in the STIP. In February 2024, the committee reviewed and approved the proposed 2024 STIP goals. In February 2025, the committee reviewed the Company’s 2024 performance and approved a STIP pool based on the performance.

##### Table of Contents

|  |  |  | 2025 Proxy Statement | 57

Target Opportunities. Each NEO has a target STIP award expressed as a percentage of base salary (prorated for Mr. Krcmarov in 2024). The target award is determined based on the following: market analysis and the committee’s market positioning assessment; the individual NEO’s organization level, scope of responsibility and ability to impact Hecla’s overall performance; and internal equity among the NEOs. Actual awards are paid after the end of the STIP performance period (usually end of March or beginning of April) and can range from 0% to 200% of the target awards, based on the committee’s assessment of the Company’s actual performance and the performance of the NEO. Having a limit on our STIP awards reduces the likelihood of windfalls to executives and encourages financial discipline. It is also consistent with typical peer group practice.

For 2024, target STIP award opportunities for the NEOs were as follows:

NEO |  | Target STIP (% of base salary)
Krcmarov |  |  |  | 110 | %
Baker |  |  |  | 125 | %
Lawlar |  |  |  | 100 | %
Clary |  |  |  | 100 | %
Sienko* |  |  |  | 100 | %
Brown |  |  |  | 70 | %

* | Mr. Sienko’s target STIP was increased from 70% to 100% in August 2024 due to his promotion to SVP–GC. When calculating Mr. Sienko’s 2024 STIP, we used a prorated approach.

Performance Measures and Components. Our management develops proposed targets and goals for each Company performance measure based on a variety of factors, internal budgets, forecasts and growth targets, market expectations and strategic objectives. The committee reviews the targets and goals and then approves a performance-based compensation strategy consistent with shareholder interests. The committee also believes incentive compensation targets should be established to drive real and sustainable improvements in operating performance and the strategic position of the Company.

Performance Factors. For 2024, the performance factors under the STIP were divided into five factors (including weighting): safety (10%), environmental (10%), operations (25%), financial goals (45%), and exploration (10%).

2024 Safety Metrics (10%)

AIFR (5%)

AIFR Result |  | AIFR Reduction Target |  |  |  | Performance Value
0.87 |  |  |  |  |  | Maximum |  |  |  |  | 10 | %
1.22 |  |  |  |  |  | Target |  |  |  |  | 5 | %
1.37 |  |  |  |  |  | Minimum |  |  |  |  | 0 | %

The AIFR reduction target was set at 1.22, which was Hecla’s best prior result. Maximum was set at 0.87, and threshold was set at Hecla’s three-year trailing average of 1.37. Hecla’s actual AIFR for 2023 was 1.45. The 2024 AIFR was 1.86, which did not meet the threshold and resulted in a performance value of 0%.

Leading Indicators (5%)

Leading Indicators |  | Leading Indicators Target |  |  |  | Performance Value

The leading indicator goal was created to motivate positive safety behaviors at mine sites such as hazard identification, risk reduction and management field presence. Each site set targets for three leading indicators. For the leading indicator roll-up, threshold was for the sites to achieve, on average, 100% of their targets; target was to reach 110%; and maximum was to exceed 120%. Examples of leading indicators include: (i) regular systematic inspections, field engagement/interactions, and corrective actions applying engineered or higher controls. The mine sites achieved 107% of target, which was between threshold and target and resulted in a performance value of 2%.

20% |  |  |  |  |  | Maximum |  |  |  |  | 20 | %
10% |  |  |  |  |  | Target |  |  |  |  | 10 | %
0% |  |  |  |  |  | Minimum |  |  |  |  | 0 | %

The Environmental goal is focused on reducing the number of reportable incidents by operating site. Each site will have a value of one-quarter of the 10% overall target value, or 2.5% each. Target for each site was to reduce their reportable incidences by 10%, based on their respective two-year trailing averages. Threshold was based on the two-year trailing average figures. Maximum was set at a 20% reduction. In order to achieve maximum value, each site would need to reduce its reportables by 20%. Three of the sites achieved at least a 20% reduction, while at the other sites reportable incidents increased. The 2024 reduction in reportable incidents was between target and maximum which resulted in a performance value of 15%.

2024 Operations (25%)

Silver Equivalent Ounce Production

Production Result |  | Production in Silver Equivalent Ounces (includes all metals) Target |  |  |  | Performance Value

100% |  |  |  |  |  | Target |  |  |  |  | 25 | %
<97% |  |  |  |  |  | Minimum |  |  |  |  | 0 | %

Target was set at achieving budgeted production results, or 100% of budgeted AgEq ounces, which was 40.6 million AgEq ounces based on conversion ratios using average 2024 prices. Threshold was set at a decrease of 1,300,000 AgEq ounces, and maximum was set at an increase of 1,300,000 AgEq ounces. 2024 AgEq ounce production resulted in only 38 million AgEq ounces, 94% of target, or roughly 2.6M AgEq ounces below target. The results were below threshold, which resulted in a performance value of 0%.

2024 Financials (45%)

Mine Site Operating Cash Flow (15%)

The 2024 benchmarks were based on production at budgeted prices of $20/oz. silver, and $1,850/oz. gold for threshold, $23/oz. and $2,020/oz. for target, and $25/oz. and $2,050/oz. for maximum. We convert gold, lead, and zinc to silver equivalent ounces, at the following ratios: 84.2 oz. silver to 1 oz. gold, 29.3 lbs. of lead to one ounce of silver, and 20.8 lbs. of zinc to one ounce of silver. The

conversion ratios are based on the average 2024 metals prices. The combined metal production results were approximately 93.6% of budget. Our 2024 mine site operating cash flow was $217.2M which was between target and maximum, which resulted in a performance value of 28%.

AISC/AgEq ounce (15%)

Capital Result |  | AISC/AgEq Ounce Target |  |  |  | Performance Value
$13.00 |  |  |  |  |  | Maximum |  |  |  |  | 30 | %

$16.00 |  |  |  |  |  | Minimum |  |  |  |  | 0 | %

Target was set at $15/oz. which was approximately the budgeted AISC of $14.90/oz. Threshold was set at 107% of target at $16/oz., and maximum was calculated at roughly 87% of target, which was $13/oz. Our 2024 AISC per AgEq ounce was $13.07, which was near maximum value and resulted in a performance value of 29%.

Capital Spending (15%)

Capital Spending |  | Capital Spending Target |  |  |  | Performance Value

$231M |  |  |  |  |  | Minimum |  |  |  |  | 0 | %

This goal was based on the Board’s approved revised budget of $210M in capital. Threshold was set at approximately 110% of target, and maximum was set at $197M, which was the original approved budgeted capital spending figure. Our 2024 capital spending was $215M, which was between threshold and target, resulting in a performance value of 12%.

2024 Exploration (10%)

Maintaining Reserves (5%)

The target was to maintain reserves. Threshold was set at replacing 50% of the AgEq ounces mined at Greens Creek, Keno Hill, and Lucky Friday. Maximum was set at adding 25M AgEq ounces. The targeted AgEq ounces were 559M, and we ended the year with 564M AgEq ounces, thus adding roughly 5M AgEq ounces. In 2024, we added 4.6M AgEq ounces of reserves Company-wide, resulting in a performance value of 6%.

Adding Resources (5%)

The target was set at adding 10M AgEq ounces. Threshold was set at maintaining existing AgEq ounces, and maximum was set at adding 75M AgEq ounces. In 2024, our resources decreased, which resulted in a factor value of 0%.

Committee Override of Calculated Results. Based on Company and individual performance for 2024, the committee determined to assess a negative discretionary factor of 7%, for a total quantitative factor of 85% to more accurately reflect the performance results for 2024.

Summary of 2024 STIP Results

In summary, 2024 was a difficult year for Hecla, largely due to production shortfalls and higher than budgeted costs of production. Permitting issues at Keno Hill and Casa Berardi continued to create difficulty throughout the year. Safety performance was below the targeted level, and we failed to replace resources. Higher than budgeted metals prices mitigated the impact of the negative issues discussed above (other than operating cash flow that was above the targeted levels). The higher than anticipated base metals prices resulted in by-product credits that lowered our AISC below expected levels. Our environmental goal had a positive aspect, with three of the four operating mines achieving their goal of reducing reportable environmental exceedances by 10%.

NEO Year-end 2024 Performance as a Group. The STIP resulted in a Company-wide corporate performance that the committee concluded to be 92% but used a negative discretionary factor of 7%, for a total corporate performance value of 85%. Each NEO’s performance is mostly based on the Company-wide corporate performance as a whole; however, the committee believes that other corporate goals specifically achieved under each NEO’s area of responsibility should be taken into account, as they support and help achieve the Company-wide strategic objectives. After the end of the year, the committee reviews and sets the corporate performance value, and the CEO reviews each other NEO’s performance against certain corporate performance goals in his or her area of responsibility and makes a recommendation to the committee. The following is a summary description of the 2024 corporate performance results, which is also based on the following for the NEOs as a group, except our CEO. Our former CEO departed from the company on May 22, 2024. Mr. Krcmarov joined the Company on November 7, 2024, and received a prorated portion of the 2024 STIP.

LTIP

The committee determined to discontinue the LTIP starting in 2024 to align our executive compensation program with our peers. The only remaining open LTIP performance period is the 2023-2025 LTIP.

Previously, we used the LTIP to focus employees on meeting long-term (three-year) performance goals. The LTIP was also designed to attract and retain employees in a highly competitive market for talent. The committee considers mining and general industry market practices, as well as the long-term objectives of the Company, when determining the terms and conditions of long-term incentive goals, such as resource additional, production, and cash flow generation. Under the LTIP, a new performance period begins each calendar year and runs for three years. The three-year performance period recognizes that some value-creating activities require a significant period of time to be implemented and for measurable results to accrue. Starting a new performance period each year also gives the committee flexibility to adjust for new business conditions, circumstances, or priorities in setting the performance metrics and goals for each three-year cycle. Performance units are assigned to each NEO at the beginning of each three-year period and provide the basis for the amount of awards made to each NEO under the LTIP. Performance units are designed to encourage management to deliver long-term value. Performance units reinforce Hecla’s business strategy by clearly establishing our key performance elements (e.g., reserve growth, production growth, and cash flow) and the associated long-term performance objectives that must be met for us to be successful and create value for shareholders. LTIP awards are paid out in the first half of the year following the end of each performance period, upon approval by the committee. At the discretion of the committee, the payouts may be in the form of cash, common stock, or a combination of both.

Summary of 2022-2024 LTIP. In February 2022, the committee approved the 2022-2024 LTIP, which has a target value of $90 per unit and a maximum potential value of $525 per unit. The 2022-2024 LTIP consists of four performance goals (maintenance of reserves, (based on silver equivalent including gold); target resource growth, 40 million ounces (based on silver equivalent including gold), target production growth, 90 million ounces (silver equivalent, including only gold); and mine site operating cash flow target, $800 million. The 2022-2024 LTIP also includes a TSR multiplier described in further detail on the next page. Payout under the LTIP takes place in late March or early April of the year following the three-year LTIP period, upon approval by the committee.

The measured performance goals for the 2022-2024 LTIP were maintenance of reserves, resource growth, production, and cash flow generation – as well as a positive or negative multiplier based on TSR. The committee concluded these goals were important for the following reasons:

• |  | Maintenance of reserves. Silver-equivalent reserves remain a fundamental value creator. We need to replace and add reserves to extend mine lives and grow production. This is critical to the achievement of our long-term success. In the context of this plan, reserves include the silver equivalent of gold but not base metals. Silver equivalent reserve and resource growth included gold converted to silver equivalent at a ratio of one ounce of gold to 82.5 ounces of silver.

• |  | Silver equivalent resource growth. Exploration success is needed in order to add to and increase resources to a sufficient size for conversion to reserves for potential new mining opportunities. Silver equivalent reserve and resource growth included gold converted to silver equivalent at a ratio of one ounce of gold to 82.5 ounces of silver.

• |  | Production. One of the most important components of value creation is demonstrable production growth (includes silver and gold, but not base metals). The gold to silver ratio is set at 82.5. In order to incentivize consistent and sustained production growth, the performance value will be reduced by 10% for any year, within the three-year LTIP period when the production for the current year is lower than the production for the prior year.

• |  | Mine site operating cash flow less capital. We endeavor to ensure that each operating site generates free cash flow, and this net cash contribution goal reflects that operating philosophy. The silver and gold costs per ounce and production at each mine site, were those contained in our long-range plan for the three-year period. This goal also includes the impact associated with any acquisitions (or dispositions) of operating mine sites.

TSR is a key element of the LTIP because it provides a relative performance metric to our peers. This component of the LTIP is different than the other components in that the TSR serves as a multiplier (either positive or negative). This component insures alignment of the results of the other components with share performance. If our relative TSR performance is in the mid-range (9th – 14th), the multiplier is 100% of the value achieved by the other three components and thus has no positive or negative affect on the unit value earned. If our relative TSR is in the top eight, the multiplier is positive and thus would enhance the unit value because the relative TSR was strong. If our relative TSR is in the bottom nine, the multiplier is negative and would reduce the overall value earned through the three-unit value factors. Regardless of the unit value earned by the unit value factors, in the event the absolute TSR is negative, the multiplier is limited to no greater than 100% of the value earned by the unit value factors. In order to achieve maximum levels, we must maintain a positive TSR on an absolute basis.

2022-2024 LTIP Targets and Results

Measured Performance Goal |  | Target Amount |  | Actual Amount
Maintenance of silver-equivalent reserves (includes only gold) |  | 0 million AgEq |  | (6) million AgEq
Silver-equivalent resource growth (includes only gold) |  | 40 million AgEq |  | 129 million AgEq
Production of silver-equivalent ounces |  | 90 million |  | 83.4 million
Mine site operating cash flow |  | $800 million |  | $826 million
TSR |  | Median |  | Median

Maintenance of Reserves. During the first and third years of the 2022-2024 Plan period, we achieved growth in the reserves but experienced a decrease in reserves during the second year. The reserve losses in 2023, which were largely in gold, slightly offset the reserve gains from 2022 and 2024, and resulted in a decrease in reserves of approximately 6 million silver equivalent ounces, which was below target, but above threshold. This resulted in a payout of $17 per unit.

Resource growth. During 2022 and 2023, resource growth was strong due to the acquisition of the Keno Hill mine and ATAC property in the Yukon. Both silver and gold resources were added in 2022 and 2023. Resources were not replaced in 2024 largely due to a limited exploration program. Over the course of the three-year plan period, 129 million silver equivalent ounces were added to the resource. This resulted in a payout of $22.25 per unit.

Production. Production was approximately 7% below budget across the three-year plan period. Underperformance at Keno Hill, the 2023 fire at Lucky Friday, and East Mine closure at Casa Berardi contributed to the shortfall. The three-year summary resulted in the production of 83.4 million AgEq or 7% below target. This resulted in a payout of $0.

##### Table of Contents

|  |  |  | 2025 Proxy Statement | 63

Mine site operating cash flow. During 2022 and 2023, mine site operating cash flows were below target by roughly 10%. During 2024, cash flows exceeded target by approximately 29%, resulting in a three-year mine site operating cash flow that was $26 million above target. This resulted in a payout of $36.44 per unit.

TSR. Hecla’s relative TSR over the three-year LTIP period was negative 4.6% and ranked 14th among the 20 peer companies (inclusive of Hecla). According to the plan, rankings of 9th through 14th among the peer group as the mid-range and earned a 100% multiple. Because the TSR multiple was 100%, it had no effect on the payout.

2022-2024 LTIP Award Summary

The 2022-2024 LTIP achieved a payout of $75.69 per unit, which was $14.31, or 16% below target for the performance period.

The following chart shows the number of performance units awarded in 2022 to each NEO then employed with us, the unit value achieved, the total amount of the award (number of units x $75.69 = total award value). The committee approved the 2022-2024 LTIP awards be paid in the form of Hecla common stock.

Equity

We have no program, plan, or practice to time the grant of stock-based awards relative to the release of material non-public information or other corporate events. All equity grants to executive officers are approved by the committee at regularly scheduled meetings or, in limited cases involving key recruits or promotions, by a special meeting or unanimous written consent. The grant date is the meeting date, or a fixed, future date specified at the time of the grant. It is not our practice to issue stock options to our NEOs (or any other employee). If we grant options in the future, we anticipate that we would do so consistent with applicable laws and our current cadence for granting equity awards. Under the terms of our 2010 Stock Plan, the fair market value of any award is determined by the closing price of our common stock on the NYSE on the date of grant or a fixed, future date specified at the time of grant. In addition, the committee typically makes equity grants to NEOs in the first half of the year.

RSUs

RSUs are granted to the NEOs under the 2010 Stock Plan. RSUs are used to (i) retain our NEOs, and (ii) to align their interests with the long-term interests of our shareholders. With the exception of Messrs. Baker and Krcmarov, and Ms. Boggs, the committee awarded RSUs to each of the other NEOs in June 2024. The RSUs vest in three equal amounts with vesting dates of June 21, 2025, June 21,

##### Table of Contents

64 | 2025 Proxy Statement |  |  |  |

2026, and June 21, 2027. See Grants of Plan-Based Awards for 2024 on page 74. Please see “CEO Transition” on page 55 for a discussion of 2024 compensation actions taken with respect to Messrs. Baker and Krcmarov, and Ms. Boggs.

We do not credit RSUs with dividend equivalents. In order to incentivize recipients to continue working for the Company, RSU awards require both an age and years of service trigger in order to qualify for continued vesting of the RSUs as of the employee’s retirement. The 2010 Stock Plan provides that for purposes of the RSU awards, in order to receive such continued vesting, the grantee must be at least age: (i) 60 and have 15 or more years of service with the Company; (ii) 65 and have seven or more years of service with the Company; or (iii) 68. If one of the above requirements is met, the recipients will receive their RSUs on applicable vesting dates.

With the exception of Messrs. Baker and Krcmarov, and Ms. Boggs, in 2024, we granted the following RSUs to our NEOs under the 2010 Stock Plan:

NEO |  | Value of RSUs Units ($) |  | Number of Shares(1) (#)
Krcmarov |  |  |  | — |  |  |  |  | — |
Lawlar |  |  |  | 368,000 |  |  |  |  | 71,180 |
Clary |  |  |  | 343,275 |  |  |  |  | 66,397 |

Boggs |  |  |  | — |  |  |  |  | — |
Baker |  |  |  | — |  |  |  |  | — |

(1) | Number of shares was determined by dividing the value of the RSUs awarded by the closing price of our common stock on the NYSE on June 21, 2024 ($5.17).

PSUs

We grant PSUs to certain executive officers, including our NEOs. The value of the awards is based in part the ranking of the TSR performance of our common stock relative to the TSR performance of the common stock of a group of peer companies over a three- year measurement period. The number of shares to be issued is based on the target value of the awards divided by the share price at grant date. The compensation cost is measured using a Monte Carlo simulation to estimate their value at grant date.

With the exception of Messrs. Baker and Krcmarov, and Ms. Boggs, in June 2024, the committee granted PSUs to our other NEOs with the target values listed below. The value of these PSUs will be based 50% on (i) the TSR of our common stock for the three-year period from January 1, 2024, through December 31, 2026, based on the percentile rank within a group of peer companies, and 50% on (ii) the achievement of mine site operating cash flow less capital expenditures (“Mine Site OCF”) versus a pre-established target. Please see “CEO Transition” on page 55 for a discussion of 2024 compensation actions taken with respect to Messrs. Baker and Krcmarov, and Ms. Boggs.

If Hecla’s performance is at the bottom of the peer group, the TSR portion of the award is zero. If Hecla’s performance is at the 25th percentile, this portion of the award is earned at 50% of target. If Hecla’s performance at the 50th percentile, this portion of the award is earned at target. If Hecla’s performance is at the 100th percentile, this portion of the award is earned at the maximum of 200%. Achievement between the foregoing levels is linearly interpolated.

The industry peer group used for purposes of the 2022-2024 TSR PSUs discussed above is listed on page 49. Threshold for the Mine Site OCF metric is 70% of target, in which case this portion of the award is earned at 50% of target. If the Mine Site OCF is 90% of target, this portion of the award is earned at target. If the Mine Site OCF is 110% of target, this portion of the award is earned at the maximum of 200%. Achievement between the foregoing levels is linearly interpolated.

2022-2024 PSU Results

In February 2025, the committee certified the results of the PSUs granted in 2022 to our then NEOs. These PSUs had a three-year performance period ended December 31, 2024, with vesting and payout based on the Company’s TSR compared to our TSR peer group (consisting of 20 companies and funds listed on page 49) from January 1, 2022, through December 31, 2024. The following table shows the calculation of the PSU results at the end of the three-year performance period on December 31, 2024. During this three-year performance period, Hecla ranked 14th among the 20 peer group companies based on TSR from 2022 through 2024, which resulted in a payout percentage of 0% of the NEOs’ targeted PSU award values. Please see the proxy statement filed in 2023 for details regarding the performance metrics.

To determine the relative share performance, Hecla’s TSR performance versus that of TSR peer group companies was based on a comparison of the average closing share price over the last 60 calendar days prior to January 1, 2022 (the base price) with the average closing share price over the last 60 calendar days of the three-year performance period (ended December 31, 2024).

The table below details the value of the PSUs based on the estimated outcome as of the date of grant. These values for the 2022 PSUs are reflected in the applicable Grants of Plan-Based Awards for 2022 table from our 2023 Proxy Statement, and the realized value of the common stock received upon settlement of the awards on February 24, 2025.

Nonqualified Deferred Compensation Plan. We maintain the KEDCP, a nonqualified deferred compensation plan, under which participants may defer all or a portion of their annual base salary, performance-based compensation awarded under our STIP and LTIP, RSUs and PSUs granted under the 2010 Stock Plan. Participants may elect to have their deferred base salary, STIP (cash or common stock) or LTIP (cash or common stock) awards credited to an investment (cash award) or stock account (for stock awards only). The KEDP was frozen effective January 2025.

Prior to January 1, 2025, deferred RSUs and PSUs could also be credited to a stock account. The deferral features promoted alignment of the interests of participants with those of our shareholders. Investment accounts are credited monthly with an amount based on the prime rate for corporate borrowers. Participants receive distributions from their accounts only upon separation from service with us, a fixed date or schedule selected by the participant, death, disability, an unforeseeable emergency, or a change in control, as these events are defined under Section 409A of the Internal Revenue Code. The amounts deferred are unfunded and unsecured obligations of Hecla, receive no preferential standing, and are subject to the same risks as any of our other general obligations. In 2024, the committee froze the KEDCP, preventing new participants from joining the KEDCP. Effective January 2025, no existing participant (including NEOs) can make a new deferral election. Additional details about the KEDCP are described in the narrative accompanying the Nonqualified Deferred Compensation for 2024 table on page 80.

Benefits. We provide our employees with a benefits package that is designed to attract and retain the talent needed to manage Hecla. In 2024, the committee froze any new participation in the Retirement Plan for U.S. employees. The U.S. NEOs, are eligible to receive, health, vision and dental plans, PTO plans such as vacations and holidays, and our 401(k) plan, which includes matching contributions by Hecla of up to 6%. Canadian NEOs are eligible to participate in a similar benefits package. NEOs are eligible to receive certain additional benefits, as described below. The committee intends for the type and value of such benefits offered to be competitive with general market practices.

Other Qualified and Nonqualified Benefit Plans. Under the Final Average Salary Retirement Plan, which is a defined benefit plan, upon normal retirement, participants are eligible to receive a monthly benefit equal to a certain percentage of their final eligible Average Annual Earnings for each year of credited service. Participants in the Cash Balance Retirement Plan, which is a defined benefit plan, are eligible to take a lump sum distribution of their benefits. Additional details about the Retirement Plans are in the narrative accompanying the Pension Benefits table on page 78. Under the SERP, the amount of any benefits not payable under the Retirement Plan because of the limitations imposed by the Internal Revenue Code and/or the Employee Retirement Income Security Act (ERISA), and certain reductions of benefits, if any, due to a deferral of salary made under our KEDCP, may be paid out of our general funds, or a Rabbi Trust, to employees who are adversely affected. The Retirement Plan and SERP defined eligible earnings for purposes of the plans to include base salary plus any other cash incentives up until July 1, 2013, after which only base salary plus one-half of STIP compensation is included (no LTIP compensation is included).

Personal Benefits. We believe perquisites should be limited in scope and value. As a result, we have historically provided limited perquisites to our executive officers, typically consisting of relocation benefits for specific recruitment needs. Prior to his retirement from the Company in May 2024, the Company incurred costs for personal benefits provided to Phillips S. Baker, Jr., the Company’s former CEO. Because Mr. Baker did not reimburse the Company for these costs prior or subsequent to his retirement, we are required under SEC rules to disclose the costs of perquisites in the Summary Compensation Table for 2024 on page 72. We do not anticipate providing similar benefits in the future.

Stock Ownership Guidelines for NEOs

We believe that it is important to encourage our executive officers to hold a material amount of our common stock and to link their long- term economic interest directly to that of our shareholders. To achieve this goal, in June 2012, the committee and Board established stock ownership guidelines for the Company’s senior management. The guidelines for the CEO are six times base salary, and for the other executive officers, two times base salary. These guidelines must be achieved five years after the executive officer is hired or promoted to such position. Unvested RSUs and shares held directly are considered owned for purposes of the guidelines. If an executive officer becomes subject to a greater ownership amount due to a promotion or an increase in base salary, he or she must meet the higher ownership requirement within three years.

Because of fluctuations in the Company’s stock price, in February 2016, the committee and the Board amended the stock ownership guidelines to provide a valuation methodology that consists of valuing the shares held by using the average closing price of the Company’s common stock on the NYSE for the previous calendar year. Because share prices of all companies are subject to market volatility, the Board believes that it would be unfair to require an executive to buy more shares simply because Hecla’s stock price drops. In the event there is a significant decline in Hecla’s stock price that causes an executive’s holdings to fall below the applicable threshold, the executive will not be required to purchase additional shares to meet the threshold, but he or she generally may not sell or transfer any shares until the threshold has again been achieved.

With the exception of Mr. Krcmarov, who is not yet required to meet the minimum shareholding requirements due to assuming his current role on November 7, 2024, as of December 31, 2024, all other NEOs meet the guidelines. In the calculations for our NEOs, we include shares directly held, shares held in their 401(k) account, and unvested RSUs. We do not include unvested PSUs.

Additional information regarding shares held by our NEOs is included in the Security Ownership of Certain Beneficial Owners and Management table on page 94.

Clawback Policy

In August 2023, we amended our clawback policy to comply with the new SEC and NYSE rules. Under our clawback policy, in the event of an accounting restatement, the Company will reasonably promptly seek to recover erroneously awarded incentive compensation from executive officers. A finding of misconduct by such executive officers, or a finding of responsibility for any accounting error leading to an accounting restatement, shall not be a requirement for seeking recovery of the erroneously awarded

compensation. In the event of a restatement of our financial results as a result of material non-compliance with financial reporting requirements, the Board will review incentive compensation that was paid to our current and former executive officers under the Company’s STIP and LTIP (or any successor plans), based solely on the achievement of specific corporate financial goals (Incentive Award) during the three completed fiscal years immediately preceding the accounting restatement date. If any Incentive Award would have been lower had it been calculated based on the Company’s restated financial results, the Board will, unless determined to be impracticable, seek to recover from any executive officer, any portion of an Incentive Award paid in excess of what would have been paid based on the restated financial results.

The policy does not apply in any situation where a restatement is not the result of material non-compliance with financial reporting requirements, such as any restatement due to a change in applicable accounting rules, standards or interpretations, a change in segment designations or the discontinuance of an operation.

Insider Trading Policy

Our insider trading policy prohibits the Company, all directors, executive officers (as defined under Section 16 of the Exchange Act) and certain other employees designated as insiders from purchasing or selling any Company securities three weeks before through two days after the public release of any of our periodic results (including the filing of any Form 10-Q or Form 10-K). That same group, including all, not just certain employees, are prohibited by the same policy, from purchasing or selling any Company securities at any other time during the year while in possession of material non-public information about the Company. In addition, directors and officers are prohibited from short-term trading, short sales, options trading, trading on margin, hedging or pledging any securities of the Company. We believe our insider trading policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and any listing standards applicable to Hecla.

Change in Control Agreements

We have entered into change in control agreements (CIC Agreements) with each of our NEOs. Under the terms of our CIC Agreements, the CEO and the other NEOs are entitled to payments and benefits upon the occurrence of specified events, including termination of employment (with or without cause) following a change in control of the Company. The specific terms of these arrangements, as well as an estimate of the compensation that would have been payable had they been triggered as of calendar year-end, are described in detail in the section titled Potential Payments Upon Termination or Change in Control on page 80.

The committee believes that these CIC Agreements are important for a number of reasons, including providing reasonable compensation opportunities in the unique circumstances of a change in control that are not provided by other elements of our compensation program. Further, change in control benefits, if structured appropriately, serve to minimize the distraction caused by a potential transaction and reduce the risk that key executives will leave Hecla before a transaction closes. The committee also believes these agreements motivate the executives to make decisions that are in the best interests of our shareholders in the event of a pending change in control. These agreements provide executives with the necessary job stability and financial security during a change in control transaction and the subsequent period of uncertainty to help them stay focused on managing Hecla rather than on their own personal employment situation. The committee believes that all these objectives (i) serve our shareholders’ interests, (ii) are an essential component of the executive compensation program and, (iii) are necessary to attract and retain senior talent in the highly competitive talent market in which we compete.

The change in control provisions were developed by the Company and the committee based on market and industry competitive practices. The Company and the committee periodically review the benefits provided under the CIC Agreements to ensure that they serve our interests in retaining our key executives, are consistent with market and industry practice, and are reasonable.

Tax and Accounting Considerations

Our compensation programs are affected by each of the following:

Accounting for Stock-Based Compensation. We consider certain requirements of GAAP in determining changes to policies and practices for our stock-based compensation programs.

##### Table of Contents

68 | 2025 Proxy Statement |  |  |  |

Section 162(m) of the Internal Revenue Code. Section 162(m) of the Internal Revenue Code of 1986, as amended (Code Section 162(m)), generally provides that compensation in excess of $1 million paid to the CEO, Chief Financial Officer, and certain other employees, including NEOs (covered employees), of a public company will not be deductible for U.S. federal income tax purposes.

Our primary objective in designing and administering our compensation policies is to support and encourage the achievement of our strategic goals and to enhance long-term shareholder value. We also believe that it is important to preserve flexibility in administering compensation programs. For these and other reasons, the committee has determined that it will not necessarily seek to limit executive compensation to the amount that would be fully deductible under Code Section 162(m).

The committee will continue to monitor developments and assess alternatives for managing the deductibility of compensation payments and benefits to the extent reasonably practicable, as determined by the committee to be consistent with our compensation policies and in the best interests of the Company and our shareholders.

Section 409A of the Internal Revenue Code. Section 409A imposes additional significant taxes in the event that an executive officer or director receives “deferred compensation” that does not satisfy the requirements of Section 409A. Our plans are intended to be exempt from, or comply with, Section 409A.

Compensation Risk Analysis

The committee has engaged in a thorough risk analysis of our compensation plans, programs, policies, and practices for all employees. This includes advice from the Company’s SVP–CAO describing the executive compensation program, and describing risk mitigation characteristics, if any, of the Company’s short- and long-term incentive programs. The committee believes the design of our compensation programs, the governance of our programs, and our risk oversight process guard against imprudent risk taking that could have a material adverse effect on the Company.

(1) | Mr. Baker departed the company on May 22, 2024. Ms. Boggs served as our ICEO from May 22, 2024 until November 7, 2024. Mr. Krcmarov became our President and CEO on November 7, 2024. Consequently, the salaries presented for them are prorated. In accordance with SEC rules, the salary presented for Ms. Boggs also includes $180,000 in director fees paid to her for 2024.

(2) | Represents RSUs awarded and PSUs granted in each of fiscal years 2024, 2023 and 2022. The amounts represent the aggregate grant date fair value of the awards granted to each NEO computed in accordance with stock-based accounting rules (FASB ASC Topic 718). Assumptions used in the calculation of these amounts are included in Note 12 – Stockholders’ Equity to our calendar year 2024 consolidated financial statements, which is included in our Annual Report on Form 10-K filed with the SEC on February 13, 2025. Consistent with the requirements of FASB ASC Topic 718, the value of PSUs is based on the estimated outcome as of the date of grant. In accordance with FASB ASC Topic 718, this result is based on a relative TSR result modeled using a Monte Carlo simulation. In accordance with SEC rules, the amount presented for Ms. Boggs reflects stock awards granted to her in 2024 in connection with her service as (i) a member of our Board (FASB ASC Topic 718 grant date fair value of $125,533), and (ii) our ICEO (FASB ASC Topic 718 grant date fair value of $283,070). Please see the Grants of Plan-Based Awards for 2024 table on page 74 for more information about the awards granted to our NEOs in 2024.

(3) | This column represents the performance payments paid to our NEOs for the calendar years 2024, 2023, and 2022 under our STIP and for the LTIP plan periods, 2022-2024, 2021-2023, and 2020-2022. As described in the Compensation Discussion and Analysis, Ms. Boggs was not eligible for an STIP opportunity in 2024. The committee determined this was appropriate not only given the temporary and transitional nature of Ms. Bogg’s role and her existing meaningful financial stake in the Company, but also given that at the time she commenced her role as ICEO, nearly half of the performance period within our 2024 annual performance-based incentive program had elapsed. Mr. Baker departed from the company on May 22, 2024, at which time he forfeited his STIP and LTIP opportunities. Mr. Krcmarov became our President and CEO on November 7, 2024; consequently, the 2024 STIP presented for him is prorated. The 2024 STIP was paid 100% in cash. The 2022-2024 LTIP was paid in common stock. At the election of the NEO, the 2023 STIP was paid in cash or common stock. The 2021-2023 LTIP was paid in common stock. The 2022 STIP and 2020-2022 LTIP were paid in cash. The awards for each of the plan years are as follows:

(4) | The amounts reported in this column for 2024 are changes between December 31, 2023 and December 31, 2024 in the actuarial present value of the accumulated pension benefits. Pension values will typically increase from year-to-year due to increasing age, years of service, and average annual earnings, and can fluctuate significantly due to changes in the assumptions used to determine the present value. The Change in Pension Value and Nonqualified Deferred Compensation Earnings column (the “Pension Value column”) is calculated pursuant to SEC requirements and is based on assumptions used in preparing the Company’s audited financial statements for the applicable calendar years. As a non-U.S. citizen, Mr. Brown is not a participant in the Hecla Mining Company Retirement Plan, or the unfunded SERP. In lieu of participation in these plans, Mr. Brown is expected to receive a similar supplement benefit as if he had participated in these plans. See Retirement Plan on page 78 for a description of non-U.S. employee’s retirement benefits.

(1) | With the exception of Ms. Boggs, whose equity awards are discussed in footnote 6, the RSU amounts represent the aggregate grant date fair value of the awards granted to each NEO computed in accordance with stock-based accounting rules (FASB ASC Topic 718). Assumptions used in the calculation of these amounts are included in Note 12 – Stockholders’ Equity to our calendar year 2024 consolidated financial statements, which are included in our Annual Report on Form 10-K filed with the SEC on February 13, 2025 (the “Form 10-K”). Consistent with the requirements of FASB ASC Topic 718, the value of PSUs is based on the estimated outcome as of the date of grant. In accordance with FASB ASC Topic 718, this result is based on a relative TSR result modeled using a Monte Carlo simulation. The amounts in this column reflect the aggregate grant date fair value of the PSUs for accounting purposes determined in accordance with SEC rules and do not reflect the actual economic value that may be realized by the NEO at the end of the relevant three-year performance period.

(2) | Mr. Krcmarov joined the Company on November 7, 2024. He did not receive any RSUs until January 2025 and will be granted PSUs in June 2025. He received a prorated amount for the 2024 STIP.

(3) | Represents the number of RSUs granted on June 21, 2024 to the NEOs under the terms of the 2010 Stock Incentive Plan. The restrictions lapse for one-third of the RSUs on June 21, 2025, one-third on June 21, 2026 and one-third on June 21, 2027, at which time the units are converted into shares of our common stock. The grant date fair value of the RSUs is the number of RSUs multiplied by the closing price of the Company common stock on the grant date of June 21, 2024 ($5.17).

(4) | Represents the number of PSUs of Hecla common stock granted under the 2010 Stock Incentive Plan, having a target value for each NEO of: Lawlar, $368,000; Clary, $343,275; Sienko, $343,275; and Brown, $312,675, with the potential of up to 200% of the target number of shares covered (subject to specific performance terms and conditions established for these shares) awarded to the NEOs under the 2010 Stock Incentive Plan. Determination of the actual number of these PSUs to be received by the NEOs will be based on the TSR of Hecla common stock for the three-year period from January 1, 2024 through December 31, 2026, based on the following percentile rank within peer group companies:

| • |  | 100th percentile rank among peers = maximum award at 200% of target;

| • |  | 50th percentile rank among peers = target award at grant value;

| • |  | 20th percentile rank among peers = threshold award at 25% of target.

| Hecla’s TSR performance versus that of peer group companies will be based on a comparison of the average share price over the last 60 calendar days prior to January 1, 2024, as the base price, and the average share price the last 60 calendar days of the three-year performance period, plus dividends, to determine relative share value performance and ranking among peers.

(5) | On June 21, 2024, Ms. Boggs was granted $125,000 in Company common stock as part of her equity grant as a member of the Board. The number of common shares granted was determined by dividing $125,000 by the average closing price for Hecla’s common stock on the NYSE for the prior calendar year ($5.148) ($125,000 ÷ $5.148 = 24,281). See footnote 3 to under Non-Management Director Compensation for 2024 on page 37. From the 24,281 shares, she elected to receive 75% of the shares immediately (18,211 shares) and to defer 25% (6,070 shares) until October 1, 2026. The grant date fair value of these shares is the number of shares (24,281) multiplied by the closing price of the Company common stock on the grant date of June 21, 2024 ($5.17).

(6) | Ms. Boggs was appointed ICEO immediately following the departure of Mr. Baker on May 22, 2024. Under the terms of the Interim Chief Executive Officer Agreement (the “ICEO Agreement”), Ms. Boggs received $106,000 per month, which was paid 60% ($63,600) in cash and 40% ($42,400) in deferred common stock at the end of each month. Partial months of service were prorated. The number of shares of deferred common stock paid to her was determined by dividing the 40% monthly equity fee by the closing price of the Company’s common stock on the NYSE on the last NYSE trading day of the applicable month, or on the last trading day prior to the termination of the ICEO Agreement, and the amounts presented in the last column of this table are based on the applicable closing price multiplied by the number of vested common shares paid to her. The grant date fair value of these shares is the number of shares multiplied by the closing price of the Company common stock on each grant date.

(7) | Mr. Baker departed from the company on May 22, 2024 and was not granted any RSUs, PSUs, or STIP awards in 2024.

(8) | Represents the potential value of the payout for each NEO under the 2024 STIP described on page 56. The 2024 STIP does not include threshold-level performance goals. The total payout to each NEO under the 2024 STIP is described in footnote 3 to the Summary Compensation Table for 2024 on page 72.

Other Benefits

Pension Benefits

Mr. Krcmarov does not participate in the Retirement Plan or SERP, and Ms. Boggs, who served as ICEO in 2024, did not participate in the Retirement Plan or SERP. The following table shows pension information under the Retirement Plan and the SERP for the NEOs as of December 31, 2024. The terms and conditions for participation in, and payments from, these plans are described below under Retirement Plan. The actuarial present value of accumulated benefit is determined using the same assumptions used for financial reporting purposes except that retirement age is assumed to be the normal retirement age of 65, or the current age if eligible for early retirement. These assumptions are described in the pension footnotes to our financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024.

Retirement Plan

Our NEOs, except for Mr. Krcmarov and Ms. Boggs, and those who are not U.S. citizens, participate in the Retirement Plan, which is a defined benefit plan. Canadian NEOs participate in Canada’s public retirement income system, which includes the following components: (i) the Canada (or Quebec) Pension Plan, which is a contributory, earnings-related social insurance program, and (ii) the Old Age Security program. In addition, the Registered Retirement Savings Plan is a tax-deferred individual savings plan also available to Canadian employees.

Contributions to the Retirement Plan, and the related expense or income, are based on general actuarial calculations and, accordingly, no portion of our contributions, and related expenses or income, is specifically attributable to our NEOs. Hecla also offers the SERP under which the amount of any benefits not payable under the Retirement Plan by reason of the limitations imposed by the Internal Revenue Code and/or the Employee Retirement Income Security Act, as amended (the “Acts”), and the loss, if any, due to a deferral of salary made under our KEDCP will be paid out of our general funds to any employee covered by the SERP who may be adversely affected. Under the Acts, the current maximum annual pension benefit payable by the Retirement Plan to any employee is $275,000 (for 2024), subject to specified adjustments, and is calculated using earnings not more than $345,000.

A Traditional Pension participant, upon reaching the normal retirement age of 65, is eligible to receive annual retirement benefits in monthly installments for life equal to, for each year of credited service, 1% of final average annual earnings (defined as the highest average earnings of such employee for any 36 consecutive calendar months for participants hired on or before June 30, 2013, and as the highest average earnings of such employee for any 60 consecutive calendar months, for participants hired after June 30, 2013, during the final 120 calendar months of service) up to the applicable covered compensation level (which level is based on the Social Security maximum taxable wage base) and 1.75% of the difference, if any, between final average annual earnings and the applicable covered compensation level.

A Cash Balance participant, upon reaching the normal retirement age of 65, is eligible to receive their account balance, or alternatively, an actuarially equivalent monthly benefit for life. The participant’s account balance is credited each quarter with pay credits equal to 3% to 6% of their eligible earnings, depending on years of service, and interest credits, as a rate equal to the quarterly rate of change in the consumer price index plus three-quarters of one percent (3/4%).

Effective July 19, 2024, no employee hired, rehired or transferred to an eligible position may (1) become a new participant in the Plan, (2) reenter the Plan as an active participant or otherwise again be considered an active participant, or (3) otherwise commence or recommend active participation in or benefit accrual under the Retirement Plan. Thus, on and after July 19, 2024, the only employees who shall actively participate in this Retirement Plan and accrue additional benefits shall be those individuals who were employed in an eligible employee position on July 18, 2024, and who otherwise meet the requirements to be a participant and actively participate in this Retirement Plan.

The Retirement Plan and SERP define earnings for purposes of the plans to be “a wage or salary for services of employees inclusive of any bonus or special pay including gain-sharing programs, contract miners’ bonus pay and the equivalent,” except that on or after July 1, 2013, earnings are defined as “base salary or wages for personal services and elective deferrals plus: (i) elective deferrals not includable in the gross income of the employee under Code section 125, 132(f)(4), 402(e)(3), 402(h), 403(b) and 457, (ii) one-half (1/2) of any performance-based or STIP bonus, (iii) one-half (1/2) of any safety incentive award, (iv) paid time off, other than pay while on disability leave, (v) any post-employment payment for services performed during the course of employment that would have been paid to the employee prior to the severance from employment if the employee had continued employment with Hecla, and (vi) compensation for overtime at the employee’s regular rate of pay.”

The following table shows estimated aggregate annual benefits under our Retirement Plan and the SERP payable upon retirement to a Traditional Pension Plan participant who retires in 2024 at age 65 having the years of service and final average annual earnings as specified. The table assumes Social Security covered compensation levels as in effect on January 1, 2024.

(1) | Canadian employees are not eligible to participate in our deferred compensation plan.

(2) | At the time of Mr. Baker’s departure from the company on May 22, 2024, he held 1,795,964 shares of Hecla common stock under the KEDCP. These shares were distributed to Mr. Baker on December 2, 2024. The value of the shares at the time of distribution is based on our closing stock price on December 2, 2024 ($5.40).

Prior to July 2024, executives, and key employees, including the NEOs, were able to defer all or a portion of their base salary, cash or equity awards earned under the LTIP and STIP, and any vested RSUs or vested PSUs granted under the 2010 Stock Incentive Plan. Deferral elections were made by the individuals generally in the year prior to the beginning of the plan year for amounts to be earned or granted in the following year. Base salary, STIP and LTIP amounts deferred under the KEDCP were credited to either an investment account or a stock account at the participant’s election. Amounts credited to an investment account were valued in cash, credited with deemed interest, and distributed with deemed interest in cash upon a distributable event. RSUs and other common stock awarded (PSUs) under the 2010 Stock Incentive Plan and deferred by a participant were credited to a stock account. Amounts credited to the stock account of a participant were valued based upon our common stock and are delivered to the participant in shares of our common stock upon a distributable event. Effective in January 2025, our KEDCP was frozen to eliminate future deferrals under this plan.

Mr. Krcmarov’s receipt of any severance payments or benefits is subject to his signing and not revoking the Company’s then standard separation agreement and release of claims with the Company.

If Mr. Krcmarov experienced a Qualifying Termination on December 31, 2024, that was outside of the change in control period described above; he would have received cash in an amount equal to: [1.5x sum of annual salary plus + 1.5x target annual bonus + cash equal to 18 months COBRA + $20K for outplacement]. If Mr. Krcmarov experienced a Qualifying Termination on December 31, 2024, but during the change in control period described above, he would have received cash in an amount equal to: [2x sum of annual salary plus + 2x target annual bonus + cash equal to 24 months COBRA + $20K for outplacement]. If Mr. Krcmarov’s employment with the Company terminated on December 31, 2024, due to death or disability, he would have received cash in an amount equal to: [1.5x sum of annual salary plus + 1.5x target annual bonus].

CIC Agreements with Other Current NEOs. The CIC Agreements provide that each of the NEOs will serve in such executive position as the Board may direct. The CIC Agreements become effective only upon a change in control of the Company (the date of such change in control is referred to as the “Effective Date”). The term of employment under the CIC Agreements is two years from the Effective Date (except for Mr. Sienko, who has terms of three years from the Effective Date). Any CIC Agreements entered into with newly hired executives will contain an employment term of two years from the Effective Date. The CIC Agreements automatically extend for an additional year on each anniversary date of the agreements unless we give notice of nonrenewal 60 days prior to the anniversary date. Under the CIC Agreements, a change in control is, with certain limitations, deemed to occur if: (i) an individual or entity (including a “group” under Section 13(d) (3) of the Exchange Act) becomes the beneficial owner of 20% or more of either the then outstanding shares of common stock of the Company or the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors; (ii) as the result of a tender offer, merger, proxy fight or similar transaction, the persons who were previously directors of the Company cease to constitute a majority of the Board; (iii) consummation of the sale of all, or substantially all, of the assets of the Company (with certain limitations) occurs; or (iv) the approval of a plan of dissolution or liquidation.

The CIC Agreements are intended to ensure, among other things, that in the event of a change in control, each NEO will continue to focus on adding shareholder value. We seek to accomplish this by assuring that each NEO continues to receive payments and other benefits equivalent to those being received at the time of a change in control for the duration of the employment term under of the CIC Agreement. The CIC Agreements also provide that should a NEO’s employment be terminated either (i) by the NEO for good reason, or (ii) by the Company (other than for cause or disability) after the Effective Date of the CIC Agreement, the NEO would receive from us

a lump-sum defined amount generally equivalent to three times the aggregate of the annual base salary rate, the highest STIP and the prorated LTIP during the three-year period, prior to the Effective Date. For Messrs. Lawlar, Clary, and Brown, and any other CIC Agreements entered into following 2024, the lump-sum defined amount is generally equivalent to two times.

The NEOs would also be entitled to lump-sum payments representing the difference in pension and supplemental retirement benefits to which they would be entitled on (i) the date of actual termination, and (ii) the end of the three-year (or two-year where applicable) employment period under the CIC Agreements. We would also maintain such NEO’s participation in all benefit plans and programs (or provide equivalent benefits if such continued participation were not possible under the terms of such plans and programs).

A NEO whose employment has terminated would not be required to seek other employment to receive the defined benefits.

For purposes of the CIC Agreements with our current non-CEO NEOs, “Cause” generally means: (i) the willful and continued failure of the executive to perform substantially the executive’s duties with the Company or any affiliated company; or (ii) the willful engaging by the executive in illegal conduct or gross misconduct that is materially and demonstrably injurious to the Company. For purposes of the CIC Agreements with our current non-CEO NEOs, “Good Reason” generally means: (i) the assignment of any duties inconsistent in any respect with their position, authority, duties or responsibilities, or any other diminution in such position, authority, duties, or responsibilities; (ii) any failure by the Company to comply with certain of the provisions of the CIC Agreement; (iii) the Company’s requiring the executive to be based at any office other than his current office; (iv) any purported termination by the Company of the executive’s employment otherwise than as expressly permitted by the CIC Agreement; or (v) any failure by the Company to require that any successor assumes the CIC Agreement.

The following table summarizes the circumstances under which our NEOs would receive severance benefits upon termination or a change in control.

CEO Pay Ratio

We believe our executive compensation program should be internally consistent and equitable to motivate our employees to create shareholder value. Our committee strives to design a fair and competitive compensation program that will attract, motivate, and retain employees, reward performance, and provide incentives based on our performance. Under the SEC rules, we are required to provide information regarding the relationship between the annual total compensation of our CEO and the annual total compensation of our median employee (excluding our CEO) for our last completed fiscal year, which ended December 31, 2024.

Mr. Krcmarov’s annual total compensation, as reported in the Summary Compensation Table included in this proxy statement, was $226,420. Since Mr. Krcmarov was appointed CEO effective November 7, 2024, and in accordance with applicable SEC rules, we annualized his salary and bonus for his service as our CEO and added it to the other components of his pay disclosed in the Summary Compensation Table, to arrive at a value of $1,941,213. We used this value for the ratio of annual total compensation for our CEO to the annual total compensation of our median employee.

##### Table of Contents

We determined the median of the annual total compensation of our employees (excluding our CEO) as of December 31, 2024. We compared the following compensation for each employee: (i) Compensation paid in foreign currency was converted to U.S. dollars using 1.37. In determining the median total compensation of all employees, we did not make any cost-of-living adjustments to the compensation paid to any employee outside of the U.S. Once we identified our median employee, we estimated the median employee’s annual total compensation in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, yielding the median annual total compensation disclosed below.

Below is (i) calendar year 2024 annual total compensation of our CEO, Mr. Krcmarov; (ii) the calendar year 2024 annual total compensation of our median employee (excluding Mr. Krcmarov); and (iii) the ratio of the annual total compensation of our CEO to that of our median employee.

The fair value or change in fair value, as applicable, of equity awards was determined by reference to (1) for RSU awards, the closing price of our common stock on the applicable measurement date and (2) for PSU awards, a Monte Carlo simulation with reference to the risk-free rate, dividend yield and volatility assumptions as of the applicable measurement date.

| (d) | The amounts included in this column are the amounts reported in the “Change in Pension and Nonqualified Deferred Compensation” column of the Summary Compensation Table for calendar year 2024 corresponding to the aggregate change in the actuarial present value of the applicable PEO’s accumulated benefit under all defined benefit and actuarial pension plans. Please refer to the Summary Compensation Table in this Proxy Statement on page 72.

| (e) | The total pension benefit adjustments for calendar year 2024 include the aggregate of two components: (i) the actuarially determined service cost for services rendered by the applicable PEO during calendar year 2024 (the “service cost”); and (ii) the entire cost of benefits granted in a plan amendment (or initiation) during calendar year 2024 for the applicable PEO that are attributed by the benefit formula to services rendered in periods prior to the plan amendment or initiation (the “prior service cost”) for the applicable PEO, in each case calculated in accordance with U.S. GAAP. The amounts deducted or added in calculating the pension benefit adjustments for calendar year 2024 for the applicable PEO are as follows:

(6) | This column represents the average amount of “compensation actually paid” to the NEOs as a group (excluding the PEOs), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding the PEOs) during the applicable calendar year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding the PEOs) for calendar year 2024 to determine the “compensation actually paid” in calendar year 2024, using the same adjustment methodology described above in Note 4(c):

Year |  | Average Reported Summary Compensation Table Total for Non-PEO NEOs (a) ($) |  | Average Reported Summary Compensation Table Value of Non-PEO NEO Equity Awards (b) ($) |  | Average Non- PEO NEO Adjusted Value of Equity Awards (c) ($) |  | Average Reported Summary Compensation Table Change in Value of Pension Benefits for Non- PEO NEOs ($) |  | Pension Benefits Adjustments for Non-PEO NEOs ($) |  | Average Compensation Actually Paid to Non-PEO NEOs ($)

| (b) | This column represents the average of the total amounts reported for the NEOs as a group (excluding the PEOs) in the “Stock Awards” column in the Summary Compensation Table in calendar year 2024. Please refer to the Summary Compensation Table in this Proxy Statement on page 72. The amount in this column is replaced with the corresponding amount reported under the Average non-PEO NEO Adjusted Value of Equity Awards column in order to arrive at compensation actually paid for 2024.

| (c) | This column represents an adjustment to the average of the amounts reported for the NEOs as a group (excluding the PEOs) in the “Stock Awards” column in the Summary Compensation Table for calendar year 2024 determined using the same methodology described above in Note 4(c). For calendar year 2024, the adjusted amount replaces the “Stock Awards” column in the Summary Compensation Table for each NEO (excluding the PEOs) for that year. The amounts added or subtracted to determine the adjusted average amount for calendar year 2024 are as follows:

Year |  | Average Year End Fair Value of Equity Awards Granted in the Year to Non-PEO NEOs ($) |  | Average Year over Year Change in Fair Value of Outstanding and Unvested Equity Awards at FYE Granted in Prior Years ($) |  | Average Fair Value as of Vesting Date of Equity Awards Granted in the Year and Vested in the Year ($) |  | Average Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Year ($) |  | Average Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Year ($) |  | Average Value of Dividends or other Earnings Paid on Stock or Option Awards not Otherwise Reflected in Fair Value or Total Compensation in the Summary Compensation Table for the Year ($) |  | Adjusted Average Value of Equity Award ($)

| (e) | The total pension benefit adjustments for calendar year 2024 are the aggregate of two components, averaged for the NEOs as a group (excluding the PEOs) in calendar year 2024 determined using the same methodology described above in Note 4(e): The amounts deducted or added in calculating the pension benefit adjustments for calendar year 2024 are as follows:

Year |  | Service Cost ($) |  |  | Prior Service Cost ($) |  | Total Pension Benefit Adjustments ($) |
2024 |  |  | 58,761 |  |  | — |  |  | 58,761 |

(7) | Company TSR is calculated by assuming that a $100 investment was made on the day prior to the first fiscal year reported and reinvesting all dividends until the last day of each reported fiscal year.

(8) | This column represents cumulative peer group TSR computed in accordance with Note 7. The peer group used for this purpose is the following published industry index: Philadelphia Gold and Silver Index. We selected the Philadelphia Gold and Silver Index as the peer group TSR for fiscal 2024 because it is the same index that is used by the Company in the performance graph in the Company’s Form 10-K for calendar year 2024.

(9) | This column represents the amount of net income reflected in the Company’s audited financial statements for the applicable year.

(10) | Annual TSR is calculated as the change in the share price between the beginning and ending of the applicable year, plus any dividends paid during such year, divided by the share price at the beginning of the year.

Financial Performance Measures
As described in greater detail in the CD&A section of this Proxy Statement, the Company’s executive compensation program reflects a
pay-for-performance
philosophy. The metrics that the Company uses for both our short- and long-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs (each as defined and adjusted as described in the CD&A of this Proxy Statement), for the most recently completed calendar year, to the Company’s performance are as follows:

• |  | Annual Total Shareholder Return;

• |  | AISC/AgEq ounce;

• |  | Mine Site Operating Cash Flow;

• |  | Capital Spending; and

• |  | Silver Equivalent Ounce Production.

Description of the Information Presented in the Pay versus Performance Table
As described in greater detail in the CD&A section of this Proxy Statement, the Company’s executive compensation program reflects a
pay-for-performance
philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance (as described in greater detail in the CD&A section of this Proxy Statement), not all of those Company measures are presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation
S-K)
for a particular year. Compensation actually paid is influenced by numerous factors, including but not limited to the timing of new grant issuances and outstanding grant vesting, share price volatility during the calendar year, our mix of
short-
and long-term metrics, and many other factors. In accordance with Item 402(v) of Regulation
S-K,
the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.
Cumulative TSR of the Company and Cumulative TSR of the Peer Group
The TSR of the Company, assuming an initial fixed $100 investment and computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $148.71, $144.62, $166.27, $155.48, and $191.63 for 2020-2024, 2020-2023, 2020-2022, 2020-2021 and 2020, respectively. The TSR of the Company’s peer group selected for this fiscal year (the Philadelphia Gold and Silver Index), assuming an initial fixed $100 investment and computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $139.24, $125.65, $118.52, $127.24, and $136.04 for 2020-2024, 2020-2023, 2020-2022, 2020-2021 and 2020, respectively.

Please see Note 7 and Note 8, above, for additional information related to the computation of Company TSR and peer group TSR, respectively. Assuming an initial fixed $100 investment and computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
the Company’s cumulative TSR over the period covered in the Pay versus Performance table increased to $148.71. In directional alignment with such Company TSR, assuming an initial fixed $100 investment and computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
the peer group’s cumulative TSR over such period increased to $139.24. Over such period, the Company’s cumulative TSR increased by approximately 49% and the peer group’s TSR increased by approximately 39%. Consequently, the increase in the Company’s TSR was greater than the increase in the peer group’s TSR over the period covered in the Pay versus Performance table.
Compensation Actually Paid and Cumulative Company TSR
The compensation actually paid to our First PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $(32,491), $2,922,539, $6,145,949, $3,177,762, and $7,046,358 for 2024, 2023, 2022, 2021 and 2020, respectively. The compensation actually paid to our Second PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $1,015,338 for 2024. The compensation actually paid to our Third PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was 226,420 for 2024. The average amount of compensation actually paid to the other NEOs as a group (excluding the PEOs), as computed in accordance with Item 402(v) of Regulation
S-K,
was $
1,288,956
, $
682,571
, $
1,674,298
, $
305,615
, and $
2,457,104
for 2024, 2023, 2022, 2021 and 2020, respectively. The TSR of the Company, assuming an initial fixed $100 investment and computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $
148.71
, $
144.62
, $
166.27
, $
155.48
, and $
191.63
for 2020-2024, 2020-2023, 2020-2022, 2020-2021 and 2020, respectively. Please see Note 5 above for additional information related to the computation of Company TSR. Assuming an initial fixed $100 investment and computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
the Company’s cumulative TSR over the period covered in the Pay versus Performance table increased to $148.71. In contrast, the compensation actually paid to our First PEO declined from $7,046,358 to $(32,491) and the average amount of compensation actually paid to the NEOs as a group (excluding the PEOs) declined from $2,457,104 to $1,288,956 over the same period. Even if the compensation actually paid for all PEOs in 2024 is combined, such aggregate compensation actually paid declined over the period covered by the Pay versus Performance table, and is in directional contrast to cumulative Company TSR over the same period, computed in accordance with the requirements of Item 402(v) of Regulation
S-K.
Compensation Actually Paid and Company Net (Loss) Income
The compensation actually paid to our First PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $(32,491), $2,922,539, $6,145,949, $3,177,762, and $7,046,358 for 2024, 2023, 2022, 2021 and 2020, respectively. The compensation actually paid to our Second PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $1,015,338 for 2024. The compensation actually paid to our Third PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was 226,420 for 2024. The average amount of compensation actually paid to the other NEOs as a group (excluding the PEOs), as computed in accordance with Item 402(v) of Regulation
S-K,
was $1,288,956, $682,571, $1,674,298, $305,615, and $2,457,104 for 2024, 2023, 2022, 2021 and 2020, respectively. The Company’s net (loss) income, as computed in accordance with Item 402(v) of Regulation
S-K
and reflected in the Company’s audited financial statements for the applicable year, was $35.8 million, ($84.2) million, ($37.3) million, $35.1 million, and ($9.5) million for 2024, 2023, 2022, 2021 and 2020, respectively. The Company’s net (loss) income over the period covered in the Pay versus Performance table increased from ($9.5) million to $35.8 million. In contrast, the compensation actually paid to our First PEO declined from $7,046,358 to $(32,491) and the average amount of compensation actually paid to the NEOs as a group (excluding the PEOs) declined from $2,457,104 to $1,288,956 over the same period. Even if the compensation actually paid for all PEOs in 2024 is combined, such aggregate compensation actually paid declined over the
period
covered by the Pay versus Performance table, and is in directional contrast to the Company’s net (loss) income over the same period.
Compensation Actually Paid and Annual TSR
The compensation actually paid to our First PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $(32,491), $2,922,539, $6,145,949, $3,177,762, and $7,046,358 for 2024, 2023, 2022, 2021 and 2020, respectively. The compensation actually paid to our Second PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was $1,015,338 for 2024. The compensation actually paid to our Third PEO, as computed in accordance with the requirements of Item 402(v) of Regulation
S-K,
was 226,420 for 2024. The average amount of compensation actually paid to the other NEOs as a group

(excluding the PEOs), as computed in accordance with Item 402(v) of Regulation
S-K,
was $1,288,956, $682,571, $1,674,298, $305,615, and $2,457,104 for 2024, 2023, 2022, 2021 and 2020, respectively. The Company’s Annual TSR, computed as described in Note 10 above, was 2.8%, (13.0)%, 6.9%, (18.9)%, and 91.63, for 2024, 2023, 2022, 2021 and 2020, respectively. The Company’s Annual TSR over the period covered in the Pay versus Performance table decreased from 91.6% to 2.8%. In directional alignment with such Annual TSR, the compensation actually paid to our First PEO declined from $7,046,358 to $(32,491) and the average amount of compensation actually paid to the NEOs as a group (excluding the PEOs) declined from $2,457,104 to $1,288,956 over the same period. Even if the compensation actually paid for all PEOs in 2024 is combined, such aggregate compensation actually paid declined over the period covered by the Pay versus Performance table, and is in directional alignment with the Company’s Annual TSR over the same period. We believe this indicates alignment between compensation actually paid and Company share price performance.

Other Matters

Certain Relationships and Related-Party Transactions

Transactions with related persons are those that involve our directors, executive officers, director nominees, greater than 5% shareholders, immediate family members of these persons, or entities in which one of these persons has a direct or indirect material interest. Transactions that are reviewed as related-party transactions by us are transactions that involve amounts that would exceed $120,000 (the current threshold required to be disclosed in the Proxy Statement under SEC and NYSE rules) and certain other transactions. Pursuant to our Code of Conduct, employees and directors have a duty to report any potential conflicts of interest to the appropriate level of management or to the Governance Committee. Our Board and NEOs respond to a quarterly related-party transaction questionnaire prepared by our corporate legal department. We then evaluate these quarterly reports along with responses to our annual director and officer questionnaires for any indication of possible related-party transactions. Our legal staff is primarily responsible for the development and implementation of processes and controls to obtain information from the directors and executive officers with respect to related-party transactions. If a transaction is deemed by us to be a related-party transaction, the information regarding the transaction is discussed with the Board. As required under the SEC rules, transactions that are determined to be directly or indirectly material to Hecla or a related party are disclosed in our Proxy Statement. In 2024, we had no related-party transactions and, as of the date of this Proxy Statement, no related-party transactions are proposed.

Political Contributions and Engagement

Government policy is one of the most powerful external forces affecting Hecla today. New laws and changes to existing laws can fundamentally impact the Company’s operations and the markets where we do business – and in turn, our bottom line, thereby affecting us and our employees, retirees, communities, and shareholders. It is important for government leaders to understand the impact of such actions. Because the impact of government policy is so critical to our survival and success, we participate in the political process and advocate in a responsible and constructive manner on issues that advance the Company’s goals and protect shareholder value. We are committed to the highest standard of ethical conduct in our involvement in policymaking and political process. We maintain the Hecla Mining Company Political Action Committee (“Hecla PAC”), which is a forum for our employees and directors to voluntarily contribute to a fund that supports the election of candidates to Congress that support a regulatory and legislative environment constructive to the operation and development of our mines. The Hecla PAC is organized under the provisions of the Federal Election Campaign Act of 1971, as amended. Decisions about contributions to specific federal candidates are made by members of the Hecla PAC. In total, our employees contributed $7,400, and our directors contributed $5,000, to the Hecla PAC in 2024. The Hecla PAC then contributed those funds to federal candidates, state and local parties, and associations who are advocates for the natural resources industry. We file all required Hecla PAC contribution reports with the Federal Election Commission.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires our directors, executive officers, and holders of more than 10% of our common stock to file with the SEC reports regarding their ownership and changes in the ownership of our common stock. These persons are required by the SEC to furnish us with copies of all Section 16(a) forms they file. The SEC has designated specific due dates for these reports, and we must identify in this Proxy Statement those persons who did not file these reports when due. To our knowledge, and based solely on our review of copies of such forms, or written representations from certain reporting persons that no such forms were required, we believe that during the calendar year ended December 31, 2024, all filing requirements applicable to our officers, directors and greater than 10% owners of our common stock were timely filed.

Shareholder proposals to be included in next year’s Proxy Statement

We will comply with Rule 14a-8 under the Exchange Act with respect to any shareholder proposals that meet that rule’s requirements. We will review shareholder proposals intended to be included in our Proxy Statement for the 2025 Annual Meeting of Shareholders which are received by us at our principal executive offices located at 6500 N. Mineral Drive, Suite 200, Coeur d’Alene, Idaho 83815-9408, no later than December 5, 2025. Such proposals must be submitted in writing and should be sent to the attention of our Corporate Secretary.

You may contact the Corporate Secretary at our principal executive offices for a copy of the relevant Bylaw provisions regarding the requirements for making shareholder proposals and nominating director candidates.

PROPOSAL 4

Approval Of The Amendment To Our Restated

Certificate of Incorporation Increasing The Number of

Authorized Shares Of Our Common Stock

The Board believes that it is in the Company’s best interest to approve a proposal to amend our Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 750,000,000 to 1,250,000,000. The terms, including the par value, of the common stock will remain unchanged.

As of March 26, 2025, 632,310,356 of our 750,000,000 currently authorized shares of common stock were issued and outstanding. Of the remaining authorized shares of common stock, 14,048,647 shares in the aggregate were reserved for issuance in connection with: (i) our stock-based compensation plans; and (ii) conversion of our outstanding Series B Cumulative Preferred Stock. As of March 26, 2025, 157,756 shares of our 5,000,000 currently authorized shares of preferred stock were issued and outstanding.

Reasons for the Proposed Increase in Authorized Capital

The purpose of the proposed amendment is to allow us to have a sufficient number of shares of authorized and unissued common stock to be used for such corporate purposes as may, from time-to-time, be considered advisable by the Board. Having such shares available for issuance in the future will give Hecla greater flexibility and will allow the shares to be issued as determined by the Board without the expense and delay of a special meeting of our shareholders to approve the additional authorized capital stock. The corporate purposes for which we may issue common stock could include, without limitation, acquisitions of other companies or assets, exchange offers for debt or other equity, new equity offerings to raise capital, stock splits, paying stock dividends, and providing incentives to employees, officers and directors pursuant to our various stock plans or in connection with the adoption of additional stock-based incentive plans. The Board will determine the terms of any issuance of additional shares.

Possible Effects of the Proposed Amendment

The increase in our authorized common stock will not have any immediate effect on the rights of existing shareholders. To the extent that the additional authorized shares are issued in the future, such shares will have a dilutive effect on the voting power and percentage equity ownership of our existing shareholders and, depending on the price at which they are issued, may have a dilutive effect on both the book value and market value of shares owned by our existing shareholders. The holders of our common stock have no preemptive rights to subscribe for or purchase any additional shares of our common stock that may be issued in the future.

We have not proposed the increase in the authorized number of shares with the intention of using the additional shares for anti-takeover purposes, although we could theoretically use the additional shares to make it more difficult or to discourage an attempt to acquire control of the Company because the issuance of such additional shares could be used to dilute the stock ownership or voting rights of a person seeking to obtain control of us.

No further action or authorization by our shareholders would be necessary prior to the issuance of the additional shares authorized by the proposed amendment to our Restated Certificate of Incorporation unless required in a particular transaction by applicable provisions of the Restated Certificate of Incorporation, law or by the regulations of a stock exchange or other regulatory agency. Therefore, there may be instances where we have a sufficient number of authorized but unissued shares to engage in a transaction, but we would still need shareholder approval to enter into the transactions.

We do not have any current plans, agreements, or understandings for stock issuances which in the aggregate would involve the use of a number of shares that exceeds the amount currently authorized but unissued.

On February 19, 2025, the Board unanimously adopted resolutions setting forth the proposed amendment to our Restated Certificate of Incorporation declaring its advisability and directing that the proposed amendment be submitted to the shareholders for their approval at the Annual Meeting. If adopted by the shareholders, the amendment will become effective upon filing of an appropriate amendment to our Restated Certificate of Incorporation with the Delaware Secretary of State.

The full text of the proposed revised Section 1 of Article IV of our Restated Certificate of Incorporation is set forth as follows:

ARTICLE IV.

Capital Stock

Section 1. Authorized Capital Stock. The Corporation will be authorized to issue two classes of shares of Capital Stock to be designated, respectively, “Common Stock” and “Preferred Stock;” the total number of shares of Capital Stock which the Corporation shall have authority to issue is One Billion Two Hundred Fifty-Five Million (1,255,000,000). One Billion Two Hundred Fifty Million (1,250,000,000) shares shall be Common Stock, $0.25 par value per share, and Five Million (5,000,000) shares shall be Preferred Stock, $0.25 par value per share.

Required Vote

Adoption of the proposed amendment to our Restated Certificate of Incorporation increasing the number of authorized shares of our common stock will require the affirmative vote of a majority of votes cast. Abstentions and broker non-votes are not counted as votes cast for this purpose and will have no effect on the outcome of the vote. A broker holding shares in street name may vote on this “routine” proposal in the absence of instructions from the beneficial owner.

You may vote “FOR,” “AGAINST” OR “ABSTAIN” on the proposal to approve the amendment to our Restated Certificate of Incorporation to Increasing the Number of Authorized Shares of our Common Stock.

|  |  |  |  |  | The Board recommends shareholders vote “FOR” the amendment to our Restated Certificate of Incorporation increasing the number of authorized shares of common stock.

What is a “shareholder of record”?

A shareholder of record or registered shareholder (record owner) is a shareholder whose ownership of Hecla stock is reflected directly on the books and records of our transfer agent, Equiniti Trust Company, LLC. If you hold Hecla stock through a bank, broker, or other intermediary, you are not a shareholder of record. Instead, you hold your stock in “street name,” and the record owner of your shares is usually your bank, broker, or other intermediary. If you are not a record owner, please understand that Hecla does not know that you are a shareholder, or how many shares you own.

Are there Rules of Conduct for the Annual Meeting?

Yes, the Rules of Conduct for the Annual Meeting will be available on the Annual Meeting Website on the date of the Annual Meeting. The Rules of Conduct will provide information regarding the rules and procedures for participating in the Annual Meeting.

What is the “record date” for the Annual Meeting?

March 26, 2025

How many shares of Hecla stock are outstanding?

As of March 26, 2025, there were 632,310,356 shares of common stock outstanding and entitled to be voted. Shares of our common stock that are held by us in our treasury are not counted as shares outstanding and will not be voted. Each shareholder has one vote for each share of common stock held as of the Record Date.

I understand that a “quorum” of shareholders is required for Hecla to transact business at the Annual Meeting. What constitutes a quorum?

A quorum must be present for business to be conducted at the Annual Meeting. A quorum consists of the presence at the Annual Meeting, in-person or represented by proxy, of a majority of the outstanding shares of our common stock as of the Record Date. Shares represented by proxies marked “Abstain” and “broker non-votes” are counted in determining whether a quorum is present for the transaction of business at the Annual Meeting.

Which Hecla shares will be entitled to vote at the Annual Meeting?

Hecla’s common stock ($0.25 par value per share) is the only class of security entitled to vote at the Annual Meeting. Each record owner and each shareholder who holds stock in street name at the close of business as of the record date is entitled to one vote for each share held at the meeting, or any adjournment or postponement.

How can I vote my shares?

Even if you plan to attend the Annual Meeting virtually, we encourage you to vote your shares in advance online, by phone, or by mail to ensure that your vote will be represented at the Annual Meeting. If your shares are held in your name, you have the right to vote your shares at the Annual Meeting by following the instructions listed below. If your shares are held in a brokerage account or by another nominee, you are considered the beneficial owner of shares held in street name. Since a beneficial owner is not the shareholder of record, you may not vote your shares at the Annual Meeting unless you obtain a “legal proxy” from your broker or nominee that holds your shares, giving you the right to vote the shares at the Annual Meeting.

Whether you hold shares directly as a shareholder of record or beneficially in street name, you may vote without participating in the Annual Meeting. You may vote by granting a proxy or, for shares held beneficially in street name, by submitting voting instructions to your broker or nominee. In most cases, you will be able to do this by using the Internet, by telephone, or by mail if you received a printed set of the Proxy Materials.

To vote by mail:

• |  | Mark, sign, and date your proxy card; and

• |  | Return your proxy card in the enclosed postage-paid envelope.

##### Table of Contents

|  |  |  | 2025 Proxy Statement | 101

To vote by proxy over the Internet:

• |  | Have your proxy card or Notice available;

• |  | Log on to the Internet and visit the website noted on your proxy card or Notice (www.proxyvote.com);

• |  | Follow the instructions provided; and

• |  | Do not mail your proxy card.

To vote by proxy by telephone:

• |  | Have your proxy card available;

• |  | Call the toll-free number listed on your proxy card (1-800-690-6903);

• |  | Follow the recorded instructions; and

• |  | Do not mail your proxy card.

To vote during the Annual Meeting:

• |  | Shares may be voted at the meeting by completing a ballot online during the meeting at www.virtualshareholdermeeting.com/ HL2025; and

To vote your 401(k) Plan shares:

If you participate in the Hecla Mining Company Capital Accumulation Plan (401(k) Plan) and hold shares of our common stock in your 401(k) Plan account as of the Record Date, you will receive a request for voting instructions from the plan trustee (Vanguard) with respect to your 401(k) Plan shares. You are entitled to direct Vanguard how to vote your 401(k) Plan shares. If you do not provide voting instructions to Vanguard by 11:59 p.m., Eastern Daylight Time, on May 18, 2025, the Hecla shares in your 401(k) Plan account will be voted by Vanguard in the same proportion as the shares held by Vanguard for which voting instructions have been received from other participants in the 401(k) Plan.

May I change or revoke my proxy?

Yes. If you are a shareholder of record, you may revoke your proxy and change your vote at any time before your proxy is voted at the Annual Meeting, in any of the following ways:

• |  | By sending a written notice of revocation to our Corporate Secretary, if such notice is received prior to the vote at the Annual Meeting, at our principal executive offices: Hecla Mining Company, Attn: Corporate Secretary, 6500 N. Mineral Dr., Suite 200, Coeur d’Alene, ID 83815-9408;

• |  | By submitting a later-dated proxy to our Corporate Secretary prior to the vote at the Annual Meeting; or

• |  | By voting online during the meeting if you are a “shareholder of record” or a “beneficial owner.”

If you hold your shares in street name, you should contact your broker for information on how to revoke your voting instructions and provide new voting instructions.

If you hold your shares in the 401(k) Plan, you may revoke your previously provided voting instructions by filing with Vanguard either a written notice of revocation or a properly executed proxy bearing a later date prior to the deadline for voting your 401(k) Plan shares. If you hold your Hecla shares outside of the 401(k) Plan, you may vote those shares separately.

Will my votes be confidential?

Yes. All shareholder meeting proxies, ballots, and tabulations that identify individual shareholders are kept confidential and are not available for examination. In addition, the identity or the vote of any shareholder is not disclosed except as required by law.

What is “broker discretionary voting”?

This refers to the NYSE rule allowing brokers to vote their customers’ shares on certain “routine” matters in the Proxy Statement at the brokers’ discretion when they have not received timely voting instructions from their customers. The NYSE rules on broker discretionary voting prohibit banks, brokers, and other intermediaries from voting uninstructed shares on certain “routine” matters, including the election of directors and advisory vote on executive compensation. Therefore, if you hold your stock in street name and you do not instruct your bank, broker, or other intermediary how to vote on any proposal that is considered a “routine “ matter, no votes will be cast on your behalf with respect to such proposals. It is important that you cast your vote.

Are abstentions and broker non-votes counted as votes cast?

No. Abstentions and broker non-votes are not counted as votes cast and will have no effect on the outcome of the vote.

How can I contact Hecla’s transfer agent?

Contact our transfer agent either by writing Equiniti Trust Company, LLC, 48 Wall Street, Floor 23, New York, New York 10005, or by telephoning 1-800-468-9716.

What happens if I do not vote on a proposal on the proxy card?

If you properly sign and return your proxy card or complete your proxy via the telephone or Internet, your shares will be voted as you direct. If you sign and return your proxy card but do not specify how you want your shares voted, they will be voted FOR (i) the election of the nominees for Director as set forth under Election of Class III Directors; (ii) ratification of the appointment of the independent registered public accountants; (iii) approval, on an advisory basis, of our executive compensation; and (iv) approval of an amendment to our Restated Certificate of Incorporation to increase the number of authorized shares.

What is a Proxy?

A “proxy” is your legal appointment in a written document of another person to vote the shares that you own in accordance with your instructions. The persons you appoint to vote your shares are also called proxies. We have designated Rob Krcmarov, our President and CEO, and Tami D. Whitman, our Assistant Corporate Secretary, as proxies for the Annual Meeting. When you sign the proxy card, you appoint each of Mr. Krcmarov and Ms. Whitman as your representatives at the Annual Meeting. As your representatives, they will vote your shares at the Annual Meeting (including any adjournment or postponement) as you have instructed them on your proxy card.

What Votes are Required for the Proposals?

Under NYSE rules, if your shares are held in street name and you do not indicate how you wish to vote, your broker is only permitted to exercise its discretion to vote your shares on certain “routine” matters. Proposal 2 (Ratification of the Appointment of BDO USA, P.C., and Proposal 4 (Approval of Amendment to our Restated Certificate of Incorporation to Increase the Number of Authorized Shares of Common Stock) are “routine” matters. Proposal 1 (Election of Class III Directors), and Proposal 3 (Approval, on an advisory basis, of our named executive officer compensation) are “non-routine” matters. Accordingly, if you do not direct your broker how to vote for Proposals 1 or 3, your broker is not permitted to exercise discretion and is not permitted to vote your shares on such matters. This is called a “broker non-vote.”

Proposal 1 – Election of Class III Directors. Pursuant to our Bylaws, each director will be elected by the affirmative vote of a majority of votes cast at the Annual Meeting, whether in-person or by proxy. Under a majority of votes cast standard, the shares voted “for” a nominee must exceed the number voted “against” that nominee. Shareholders may vote “FOR,” “AGAINST” or “ABSTAIN” with respect to this proposal. Abstentions and broker non-votes are not counted as votes cast and thus will have no effect on the outcome of the vote. A properly executed proxy card marked “AGAINST” with respect to the election of directors will have an effect on the outcome of the vote. If the votes cast “AGAINST” an incumbent director exceed the number of votes cast “FOR” the director, the director will not be elected, will remain on the board as a holdover director and must stand for election at the next annual meeting of shareholders, absent his or her earlier resignation or removal. See Majority Voting for Directors and Director Resignation Policy on page 18 for a description of our director resignation policy.

You may vote “FOR,” “AGAINST,” or “ABSTAIN” on each nominee for election as a director.

Proposal 2 – Ratify the Appointment of BDO USA, P.C., as our Independent Registered Public Accounting Firm for 2025. Under the Sarbanes-Oxley Act of 2002, the Audit Committee has the sole authority to appoint the independent registered public accounting firm for the Company. However, the Board feels that it is important for the shareholders to approve the selection of BDO USA, P.C. This proposal requires the affirmative vote of a majority of votes cast at the Annual Meeting, whether in-person or by proxy. Abstentions and broker non-votes are not counted as votes cast and thus will have no effect on the outcome of the vote. Votes marked “AGAINST” will have an effect on the outcome of the vote. The appointment of our independent registered public accounting firm for calendar year 2025 is considered a “routine” matter and brokers that are not directed how to vote are permitted to vote shares held in street name for their customers on this proposal.

You may vote “FOR,” “AGAINST,” or “ABSTAIN” on the proposal to ratify the appointment of BDO USA, P.C. as our independent registered public accounting firm for 2025.

Proposal 3 – Approval, on an Advisory Basis, of our Named Executive Officer Compensation. For more information on approval of our executive compensation see “Proposal 3 – Approval, on an Advisory Basis, of our Named Executive Officer Compensation” beginning on page 42. The advisory vote on name executive officer compensation will require the affirmative vote of a majority of votes cast at the Annual Meeting, whether in-person or by proxy. Under a majority of votes cast standard, the shares voted “FOR” Proposal 3 must exceed the number voted “AGAINST” Proposal 3 for the proposal to be approved. Abstentions and broker non-votes are not counted as votes cast for this purpose and will have no effect on the outcome of the vote. Votes marked “AGAINST” will have an effect on the outcome of the vote. Even though your vote is advisory and therefore will not be binding on the Company, the Board’s Compensation Committee will review the voting results and take them into consideration when making future decisions regarding executive compensation.

You may vote “FOR,” “AGAINST,” or “ABSTAIN” on the proposal to approve the compensation of our NEOs.

Proposal 4 – Approval of an Amendment to our Restated Certificate of Incorporation Increasing the Number of Authorized Shares from 750,000,000 to 1,250,000,000. For more information on this proposal see “Proposal 4 – Approval of an Amendment to our Restated Certificate of Incorporation Increasing the Number of Authorized Shares of our Common Stock” beginning on page 97. Adoption of the proposed amendment to our Restated Certificate of Incorporation will require the affirmative vote of a majority of votes cast. Abstentions and broker non-votes are not counted as votes cast for this purpose and will have no effect on the outcome of the vote. A broker holding shares in street name may vote on this “routine” proposal in the absence of instructions from the beneficial owner.

You may vote “FOR,” “AGAINST” or “ABSTAIN” on the proposal to approve the amendment to our Restated Certificate of Incorporation Increasing the Number of Authorized Shares of our Common Stock.

Discretionary voting by proxies on other matters. Aside from the proposals discussed above, no other proposals have been timely submitted in accordance with our Bylaws, and we do not know of any other proposal that may be presented at the Annual Meeting. However, if any other business is properly presented at the Annual Meeting, your proxy gives authority to Rob Krcmarov, and Tami D. Whitman to vote on such matters at their discretion.

Assuming there is a proper quorum of shares represented at the Annual Meeting; how many shares are required to approve the proposals being voted upon in this Proxy Statement?

Proposal |  | Vote Required |  | Do abstentions count as votes cast? |  | Is broker discretionary voting allowed?
Election of Class III Directors |  | Majority of votes cast |  | No |  | No
Ratify the Appointment of BDO USA, P.C. |  | Majority of votes cast |  | No |  | Yes
Advisory Vote on Executive Compensation * |  | Majority of votes cast |  | No |  | No
Approval of an Amendment to our Restated Certificate of Incorporation to Increase the Number of Authorized Shares of Common Stock |  | Majority of votes cast |  | No |  | Yes

* | Advisory and non-binding

Where can I find the voting results of the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. We will publish the results in a Current Report on Form 8-K that we expect to file with the SEC within four business days of the Annual Meeting. After the Form 8-K is filed, you may obtain a copy by visiting the SEC’s website at www.sec.gov/edgar, visiting our website at https://www.hecla.com under “Investors,” and then selecting “Annual Reports & Filings,” or contacting our Investor Relations Department by writing to Investor Relations Department, Hecla Mining Company, 6500 N. Mineral Dr., Suite 200, Coeur d’Alene, ID 83815-9408 or by sending an email to hmc-info@hecla-mining.com.

I received a Notice of Internet Availability of Proxy Materials. What does this mean?

Consistent with widespread practice and in accordance with SEC rules, Hecla is distributing proxy materials to some shareholders over the Internet by sending a Notice of Internet Availability of Proxy Materials (“Notice”) that explains how to access our Proxy Materials and vote online. If you received a Notice and would like a printed copy of the proxy materials (including the Annual Report, Proxy Statement, and a proxy card in the case of record owners, or a voting instruction form in the case of shareholders holding shares in street name), please follow the instructions included in your Notice.

I received my proxy materials in hard copy. How may I arrange to receive electronic delivery of Proxy Materials, Annual Reports, News Releases, and documents filed with the SEC?

We want to communicate with you in the way that is most convenient for you. Our Proxy Materials are available on our website at https://www.hecla.com. Instead of receiving paper copies of next year’s Proxy Materials by mail, you can elect to receive an email message that will provide a link to those documents online. By opting to access your Proxy Materials online, you will:

• |  | gain faster access to your Proxy Materials;

• |  | save us the cost of producing and mailing documents to you; and

• |  | help preserve environmental resources.

If you are a shareholder of record, you may request and consent to electronic delivery of future Proxy Materials by following the instructions on your proxy card or by visiting our website at https://www.hecla.com under “Investors,” and then selecting “Electronic Proxy Request.” If your shares are held in street name, please contact your broker, and ask about the availability of electronic delivery. If you select electronic delivery, we will discontinue mailing the Proxy Materials to you beginning next year and you will be sent an email message notifying you of the Internet address or addresses where you may access the Proxy Materials. You can receive a free paper or email copy of this year’s Proxy Materials by requesting prior to May 16, 2025. If you would like to request a copy of the Proxy Materials for this and/or future shareholder meetings, you may (i) visit www.proxyvote.com, (ii) call 1-800-579-1639, or (3) send an email to sendmaterial@proxyvote.com. If sending an email, please include your control number (indicated on your Notice) in the subject line.

Your consent to electronic delivery will remain in effect until you revoke it. If you selected electronic delivery last year, we would not mail the Proxy Materials to you this year and you will receive an email message with the Internet address where you may access the Proxy Materials for the current year.

Shareholders may also elect to receive notice of our filings with the SEC, annual reports, and news releases by email. You may sign up for this service by visiting our website at https://www.hecla.com under “News & Media” and selecting “Subscribe.”

What is “householding” and does Hecla do this?

Many brokerage firms, financial institutions and transfer agents have instituted “householding” procedures for beneficial owners and shareholders of record. Householding is when a single copy of our Proxy Materials is sent to a household in which two or more shareholders reside if they appear to be members of the same family. This practice is designed to reduce duplicate mailings and save significant printing and postage costs, as well as natural resources.

If you are a beneficial owner, you may have received householding information from your broker, financial institution, or other nominee shareholder in the past. Please contact the shareholder of record directly if you have questions, require additional copies of our Proxy Materials, or wish to revoke your decision to household and thereby receive multiple copies. You should also contact the shareholder of record if you wish to institute householding. These options are available to you at any time.

However, if you choose to access the Proxy Materials over the Internet, you are responsible for any Internet access charges you may incur. Arrangements will be made with brokerage firms and other custodians, nominees, and fiduciaries for forwarding solicitation materials to the beneficial owners of the shares of common stock held by such persons, and we will reimburse such brokerage firms, custodians, nominees, and fiduciaries for reasonable out-of-pocket expenses incurred by them in connection with such activities.

Reconciliation of Non-GAAP Measures to GAAP

Reconciliation of Cash Provided by Operating Activities (GAAP) to Free Cash Flow (non-GAAP)

The non-GAAP measure of free cash flow is calculated as net cash provided by operating activities (GAAP) less additions to properties, plants, equipment, and mineral interests (GAAP). Management believes that, when presented in conjunction with comparable GAAP measures, free cash flow is useful to investors in evaluating our operating performance. The following table reconciles net cash provided by operating activities to free cash flow:

in thousands |  | December 31, 2024 |
Net cash provided by operating activities (GAAP) |  | $ | 218,277 |
Less: Additions to properties, plants, equipment, and mineral interests (GAAP) |  |  | (214,492 | )
Free cash flow(7) |  | $ | 3,785 |

Reconciliation of Mine Site Cash Provided by Operating Activities (GAAP) to Mine Site Operating Cash Flow Less Capital (non-GAAP)

The non-GAAP measure of mine site operating cash flow less capital, which is a performance measure for our LTIP, is calculated as mine site cash provided by operating activities, less additions to properties, plants, equipment, and mineral interests. Management believes that, when presented in conjunction with comparable GAAP measures, mine site operating cash flow less capital is useful to investors in evaluating our operating performance. The following table reconciles mine site cash provided by operating activities to mine site operating cash flow less capital:

in thousands |  | December 31, 2024 |
Mine site cash provided by operating activities |  | $ | 348,776 |
Additions to properties, plants, equipment, and mineral interests |  |  | (212,960 | )
Mine site operating cash flow less capital |  | $ | 135,816 |

Reconciliation of Net Income (Loss) (GAAP) to Earnings Before Interest, Taxes, Depreciation, Depletion and Amortization (non-GAAP)

The non-GAAP measure of earnings before interest, taxes, depreciation, depletion, and amortization (EBITDA) is calculated as net income (loss) before the following items: interest expense, income tax provision (benefit), and depreciation, depletion, and amortization expense. Management believes that, when presented in conjunction with comparable GAAP measures, EBITDA is useful to investors in evaluating our operating performance. The table below presents reconciliations between the GAAP measure of net income (loss) to the non-GAAP measure EBITDA for the years ended December 31, 2024, 2023 and 2022.

|  | Year ended December 31, |

EBITDA |  | $ | 306,521 |  |  | $ | 123,996 |  |  | $ | 141,817 |

(7) | Free cash flow is calculated as cash provided by operating activities (GAAP) less additions to properties, plants, equipment, and mineral interests. Free cash flow is a measure used by management to evaluate the Company’s operating performance but should not be considered as an alternative to cash flow from operations, as that term is defined by GAAP.

In addition, the Company may use it when formulating performance goals and targets under its incentive program.

Reconciliation of Income Applicable to Common Stockholders to Adjusted Net Income Applicable to Common Stockholders (GAAP)

Adjusted net income and adjusted net income per common stock, are indicators of our performance.
