Slide 2 — CAUTIONARY NOTE

CAUTIONARY NOTE Non-GAAP Measures This presentation of Pan American Silver Corp. and its subsidiaries (collectively, “Pan American”, “Pan American Silver”, the “Company”, “we” or “our”) refers to various non-GAAP measures, such as “AISC”, “adjusted earnings”, “attributable revenue”, “attributable cash flow from operations”, “attributable free cash flow”, “basic adjusted earnings per share”, “total debt”, and “working capital”. These measures do not have any standardized meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other companies. Any reference to "Attributable" in this presentation should be understood to reflect the Company's ownership share of results, which includes results from the operations that the Company has a 100% ownership interest in as well as from the operations, specifically the Juanicipio mine and the San Vicente mine, that the Company does not own a 100% interest in. Any reference to “AISC” in this presentation should be understood to mean all-in sustaining costs per silver or gold ounce sold, net of by-product credits (respectively, the “Silver Segment AISC” or “Gold Segment AISC”), presented on an Attributable basis. Readers should refer to the “Alternative Performance (Non- GAAP) Measures” section of the Company’s Management’s Discussion and Analysis (“MD&A”) for the period ended June 30, 2026, available at www.sedarplus.ca an at www.sec.gov/edgar. Reporting Currency and Financial Information Unless we have specified otherwise, all references to dollar amounts or $ are to United States dollars. Cautionary Note Regarding Forward Looking Statements and Information Certain of the statements and information in this presentation, including any information relating to Pan American’s future oriented financial information, constitute "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and "forward-looking information" within the meaning of applicable Canadian provincial securities laws. All statements, other than statements of historical fact, are forward-looking statements or information. Forward-looking statements or information in this presentation relate to, among other things: future financial or operational performance; operating outlook for 2026, including, but not limited to production, AISC and expenditures; the expectation that production will be more heavily weighted toward the fourth quarter of 2026; statements regarding the investments in capital projects, and any anticipated benefits therefrom; estimated mineral reserve and mineral resource information; Pan American’s liquidity; the aggregate value available and expected to be returned to shareholders in 2026 through dividends and share repurchases under the Company’s normal course issuer bid, including the aggregate amount of dividends that may be paid to shareholders and statements that the dividend per share is expected to increase over time; and Pan American’s plans and expectations for its properties and operations. These forward-looking statements and information reflect Pan American’s current views with respect to future events and are necessarily based upon a number of assumptions that, while considered reasonable by Pan American, are inherently subject to significant operational, business, economic and regulatory uncertainties and contingencies. These assumptions include: tonnage of ore to be mined and processed; future anticipated prices for gold, silver and other metals and assumed foreign exchange rates; the timing and impact of planned capital expenditure projects, including anticipated sustaining, project, and exploration expenditures; the ongoing impact and timing of the court-mandated ILO 169 consultation process in Guatemala; risks related to increased barriers to trade, including tariffs and duties; ore grades and recoveries; capital, decommissioning and reclamation estimates; our mineral reserve and mineral resource estimates and the assumptions upon which they are based; prices for energy inputs, labour, materials, supplies and services (including transportation); no labour-related disruptions at any of our operations; no unplanned delays or interruptions in scheduled production; all necessary permits, licenses and regulatory approvals for our operations are received in a timely manner; our ability to secure and maintain title and ownership to mineral properties and the surface rights necessary for our operations, including contractual rights from third parties and adjacent property owners; whether Pan American is able to maintain a strong financial condition and have sufficient capital, or have access to capital through our corporate credit facility or otherwise, to sustain our business and operations; the ability of the Company to continue to achieve anticipated Attributable free cash flow and that any such cash flow generation will be sufficient to achieve any particular level of returns to shareholders pursuant to the Company’s enhanced shareholder returns framework; and our ability to comply with environmental, health and safety laws. The foregoing list of assumptions is not exhaustive. Pan American cautions the reader that forward-looking statements and information involve known and unknown risks, uncertainties and other factors that may cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements or information contained in this presentation and Pan American has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: the duration and effect of local and world-wide inflationary pressures, tariffs and the potential for economic recessions; fluctuations in silver, gold and base metal prices; fluctuations in prices for energy inputs, labour, materials, supplies and services (including transportation); fluctuations in currency markets; operational risks and hazards inherent with the business of mining (including environmental accidents and hazards, industrial accidents, equipment breakdown, unusual or unexpected geological or structural formations, cave-ins, flooding and severe weather); risks relating to the credit worthiness or financial condition of suppliers, refiners and other parties with whom Pan American does business; inadequate insurance, or inability to obtain insurance, to cover these risks and hazards; employee relations; relationships with, and claims by, local communities and indigenous populations; our ability to obtain all necessary permits, licenses and regulatory approvals in a timely manner; changes in laws, regulations and government practices in the jurisdictions where we operate, including environmental, export and import laws and regulations; changes in national and local government, legislation, taxation, controls or regulations and political, legal or economic developments in Canada, the United States, Mexico, Peru, Argentina, Bolivia, Guatemala, Chile, Brazil or other countries where Pan American may carry on business, including legal restrictions relating to mining, risks relating to expropriation and risks relating to the constitutional court-mandated ILO 169 consultation process in Guatemala; diminishing quantities or grades of mineral reserves as properties are mined; increased competition in the mining industry for equipment and qualified personnel; those factors identified under the caption "Risks Related to Our Business" in Pan American's most recent Form 40-F and Annual Information Form filed with the United States Securities and Exchange Commission (“SEC”) and Canadian provincial securities regulatory authorities, respectively. Although Pan American has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended. Investors are cautioned against undue reliance on forward- looking statements or information. Forward-looking statements and information are designed to help readers understand management's current views of our near- and longer-term prospects and may not be appropriate for other purposes. Pan American does not intend, nor does it assume any obligation to update or revise forward-looking statements or information, whether as a result of new information, changes in assumptions, future events or otherwise, except to the extent required by applicable law. THIS PRESENTATION DOES NOT CONSTITUTE (AND MAY NOT BE CONSTRUED TO BE) A SOLICITATION OR OFFER BY PAN AMERICAN OR ANY OF OUR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, REPRESENTATIVES OR AGENTS TO BUY OR SELL ANY SECURITIES OF ANY PERSON IN ANY JURISDICTION, OR A SOLICITATION OF A PROXY OF ANY SECURITYHOLDER OF ANY PERSON IN ANY JURISDICTION, IN EACH CASE, WITHIN THE MEANING OF APPLICABLE LAWS. Technical Information All mineral reserves and mineral resources have been estimated in accordance with the CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”) and reported in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). Mineral resources are reported exclusives of mineral reserves. Pan American does not expect these mineral reserve and mineral resource estimates to be materially affected by metallurgical, environmental, permitting, legal, taxation, socio-economic, political, and marketing or other relevant issues. The Company has undertaken a verification process with respect to the data disclosed in this presentation. The mineral resources and mineral reserves databases comprising drilling and, in some cases, surface and underground sampling, have been compiled at each of the Pan American mine sites by the qualified staff. All the assay data used in the resource evaluation provided by each of the mines has been subjected to the industry standard quality assurance and quality control (“QA/QC”) program including the submission of certified standards, blanks, and duplicate samples. The results are reviewed monthly by management. The results of the QA/QC samples submitted for the resource databases demonstrate acceptable accuracy and precision. The Qualified Person is of the opinion that the sample preparation, analytical, and security procedures followed for the samples are sufficient and reliable for the purpose of these mineral resource and mineral reserve estimates. Pan American is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data reported herein. Quantities and grades of contained metal are shown before metallurgical recoveries. For further information on the Company’s material mineral properties, including detailed information concerning associated QA/QC and data verification matters, the key assumptions, parameters and methods used by the Company to estimate mineral reserves and mineral resources, and for a detailed description of known legal, political, environmental, and other risks that could materially affect the Company’s business and the potential development of the Company’s mineral reserves and mineral resources, see the Company’s most recent Annual Information Form, available on the Company’s profile at www.sedarplus.ca. Technical information contained in this presentation has been reviewed and approved by Christopher Emerson, FAusIMM., Senior Vice President of Exploration and Geology, and Christopher Wright P.Geo.

Does not incorporate the three to six thousand ounces shortfall as per the MD&A for the period ended June 30, 2026 // Gold production is expected to be more heavily weighted toward Q4 2026, with Q3 production expected to be three to six thousand ounces below the low-end of guidance range, and full-year production at the low-end of guidance range Attributable Silver Production is expected to be higher in H2 2026, largely as a result of increased production from Juanicipio, La Colorada, and San Vicente; partially offset by lower production at Cerro Moro and Dolores. Attributable Gold Production is expected to be at the low-end of guidance range due to shortfalls at El Peñon and Jacobina, partially offset by improvements at Timmins and Shahuindo, as a result of higher throughput and mine sequencing into higher grade ores. Silver Segment AISC per ounce are anticipated to be highest in Q4 2026 due to production impacts from Cerro Moro. Gold Segment AISC per ounce are expected to be at the high end of the annual guidance range driven by production impacts.

Capital expenditures at Juanicipio represent Pan American’s 44% ownership. 2. Capital expenditures at San Vicente represent Pan American’s 95% ownership. 3. As indicated in the news release dated May 5, 2026, the Company’s Board of Directors approved $265.1 million of project capital to be spent over the next five years to complete a first phase underground Skarn deposit access ramp. Consequently, La Colorada Skarn project capital has been increased from $47 - $50 million to $92 - $95 million. 4. Guidance range for taxes paid was increased on August 12, 2026, based on increased profitability as a result of higher metal prices than management had assumed for the first half of the year and assuming silver and gold prices of $60 per ounce and $4,000 per ounce, respectively, in the second half of 2026. 5. Depreciation and Amortization excludes depreciation at Juanicipio, which is considered an equity accounted investment. 18
