Pan American Silver Reports Unaudited Third Quarter 2024 Results, with
Record Free Cash Flow of $151.5 Million

Vancouver, B.C. - November 5, 2024 - Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") reports unaudited results for the quarter ended September 30, 2024 ("Q3 2024").

"Pan American generated record financial results in Q3 2024, including record free cash flow of $151.5 million, reflecting improved operating margins from the increase in production and silver and gold prices over Q2 2024," said Michael Steinmann, President and Chief Executive Officer. "We are on track to achieve our guidance for 2024, and we are looking forward to a strong finish for the year from a back-end loaded production profile."

"At the La Colorada mine, the new ventilation infrastructure has already resulted in a 59% increase in silver production and a 26% decline in cash costs compared to Q2 2024. We expect throughput will continue to rise, reaching 2,000 tonnes per day by the end of this year," added Mr. Steinmann.

The following highlights for Q3 2024 include certain measures that are not generally accepted accounting principles ("non-GAAP") financial measures. Please refer to the section titled “Alternative Performance (Non-GAAP) Measures” at the end of this news release for further information on these measures.

Consolidated Q3 2024 Results:

•Silver production of 5.47 million ounces.

•Gold production of 225.0 thousand ounces.

•Record revenue of $716.1 million, which excludes an approximately $30 million build-up in finished goods and concentrate inventories.

•Net earnings of $57.1 million, or $0.16 basic earnings per share.

•Adjusted earnings of $115.1 million, or $0.32 adjusted earnings per share.

•Income tax expense of $73.3 million includes: (i) a net $40.5 million in Mexico and (ii) $6.3 million in Argentina, both related to prior years' tax filings, which were partially offset by (iii) the reversal of $26.5 million of Argentine inflation-driven tax expense that was recorded in the first half of 2024. Adjusted earnings does not include the first two items, as these relate to previous years' income.

•Record cash flow from operations before non-cash working capital changes of $235.8 million, net of $26.4 million in cash taxes paid.

•Silver Segment Cash Costs and All-in Sustaining Costs ("AISC")(1)(2), excluding net realizable value ("NRV") inventory adjustments, per silver ounce of $15.88 and $20.90, respectively.

Total debt of $815.2 million is primarily related to two senior notes, as well as certain lease liabilities, construction and other loans payable.

•The Company maintains its 2024 Operating Outlook, as previously provided in its Management's Discussion & Analysis ("MD&A") dated February 21, 2024. See the "2024 Operating Outlook" section of this news release for further detail.

•A cash dividend of $0.10 per common share with respect to Q3 2024 was declared on November 5, 2024, payable on or about November 29, 2024, to holders of record of Pan American’s common shares as of the close of markets on November 18, 2024.

Q3 2024 NEWS RELEASE All amounts expressed in U.S. dollars unless otherwise indicated. Unaudited tabular amounts are in millions of U.S. dollars and thousands of shares, options, and warrants except per share amounts and per ounce amounts, unless otherwise noted.

(1) Silver Segment Cash Costs and AISC are calculated net of credits for realized revenues from all metals other than silver ("silver segment byproduct credits"), and are calculated per ounce of silver sold.

(2) Cash costs per ounce metrics, net of by-product credits, is used extensively in our internal decision-making processes. We believe the metric is also useful to investors because it facilitates comparison, on a mine-by-mine basis, notwithstanding the unique mix of incidental by-product production at each mine, of our operations’ relative performance on a period-by-period basis, and against the operations of our peers in the silver industry. Cash costs per ounce is conceptually understood and widely reported in the mining industry.

(3) Gold Segment Cash Costs and AISC are calculated net of credits for realized revenues from all metals other than gold ("gold segment by-product credits"), and are calculated per ounce of gold sold.

Q3 2024 Project Updates:

•At La Colorada, project capital of $3.6 million was directed largely to exploration and engineering on the Skarn project, and to complete the new ventilation infrastructure for the operating mine.

•At Huaron, project capital of $4.8 million was spent on the construction of the new filter plant and filter-stack tailings storage facility, which is on schedule to be substantially completed in the fourth quarter of 2024 and then be commissioned and operational by the end of Q1 2025.

•At Timmins, project capital of $2.5 million was spent to construct the paste plant and its associated infrastructure. Commissioning of the project commenced in October.

•At Jacobina, project capital of $2.5 million was invested in upgrading the plant facility infrastructure and a study aimed to optimize the mine's long-term economics and sustainability. This optimization study is expected to be released in the first half of 2025.

•At Escobal, the Guatemalan Ministry of Energy and Mines (“MEM”) appointed Mr. Luis Pacheco as Vice Minister of Sustainable Development in August. This position, responsible for overseeing the ILO 169 consultation process for the mine, had been vacant since April 29, 2024. During Q3 2024, Mr. Pacheco visited the mine along with other members of the MEM and held working meetings regarding the consultation process. The MEM has communicated to the Company that the Xinka Parliament is in the process of conducting meetings in their communities, but no new timeline has been published yet nor have any plenary activities been scheduled. The Escobal mine remains on care and maintenance and there is no date for a restart of operations.

2024 OPERATING OUTLOOK

Please see Pan American's MD&A dated February 21, 2024, for further detail on the Company's 2024 Operating Outlook. Please also refer to the Cautionary Note Regarding Forward-Looking Statements and Information at the end of this news release.

The Company reaffirms its 2024 Operating Outlook for annual production, Cash Costs and AISC, and capital expenditures. As indicated in the Company's MD&A dated August 7, 2024, the Company expects 2024 silver and gold production to be more heavily weighted to the fourth quarter of 2024 than originally indicated in its 2024 Quarterly Operating Outlook, and annual silver production to be towards the low end of the annual guidance range.

Additionally, cash income tax payments in Q4 2024 are now expected to be between $70.0 million to $90.0 million, which includes: $45.9 million of income taxes paid in October 2024 related to a settlement with the Mexican tax authorities, $6.3 million payable in Argentina related to an amendment of income tax filings, and a higher rate of installments to account for the increase in profitability from higher metal prices.

Alternative Performance (Non-GAAP) Measures

In this news release, we refer to measures that are non-GAAP financial measures. These measures are widely used in the mining industry as a benchmark for performance, but do not have a standardized meaning as prescribed by IFRS as an

PAN AMERICAN SILVER CORP. 5

Q3 2024 NEWS RELEASE All amounts expressed in U.S. dollars unless otherwise indicated. Unaudited tabular amounts are in millions of U.S. dollars and thousands of shares, options, and warrants except per share amounts and per ounce amounts, unless otherwise noted.

indicator of performance, and may differ from methods used by other companies with similar descriptions. These non-GAAP financial measures include:

•Cash Costs. Pan American's method of calculating cash costs may differ from the methods used by other entities and, accordingly, Pan American's Cash Costs may not be comparable to similarly titled measures used by other entities. Investors are cautioned that Cash Costs should not be construed as an alternative to production costs, depreciation and amortization, and royalties determined in accordance with IFRS as an indicator of performance.

•Adjusted earnings and basic adjusted earnings per share. Pan American believes that these measures better reflect normalized earnings as they eliminate items that in management's judgment are subject to volatility as a result of factors, which are unrelated to operations in the period, and/or relate to items that will settle in future periods.

•All-in Sustaining Costs per silver or gold ounce sold, net of by-product credits. Pan American has adopted AISC as a measure of its consolidated operating performance and its ability to generate cash from all operations collectively, and Pan American believes it is a more comprehensive measure of the cost of operating our consolidated business than traditional cash costs per payable ounce, as it includes the cost of replacing ounces through exploration, the cost of ongoing capital investments (sustaining capital), general and administrative expenses, as well as other items that affect Pan American's consolidated earnings and cash flow.

•Total debt is calculated as the total current and non-current portions of: debt, including senior notes and amounts drawn on the SL-Credit Facility, and lease obligations. Total debt does not have any standardized meaning prescribed by GAAP and is therefore unlikely to be comparable to similar measures presented by other companies. Pan American and certain investors use this information to evaluate the financial debt leverage of Pan American.

•Working capital is calculated as current assets less current liabilities. Working capital does not have any standardized meaning prescribed by GAAP and is therefore unlikely to be comparable to similar measures presented by other companies. Pan American and certain investors use this information to evaluate whether Pan American is able to meet its current obligations using its current assets.

•Total available liquidity is calculated as the sum of cash and cash equivalents, Short-term Investments, and the amount available on the SL-Credit Facility. Total available liquidity does not have any standardized meaning prescribed by GAAP and is therefore unlikely to be comparable to similar measures presented by other companies. Pan American and certain investors use this information to evaluate the liquid assets available to Pan American.

•Free cash flow is calculated as net cash generated from operating activities less sustaining capital expenditures. Free cash flow does not have any standardized meaning prescribed by GAAP and is therefore unlikely to be comparable to similar measures presented by other companies. Pan American and certain investors use this information to evaluate the profitability of Pan American and identify capital that may be available for investment or return to shareholders.

Readers should refer to the "Alternative Performance (non-GAAP) Measures" section of Pan American’s Q3 2024 MD&A for a more detailed discussion of these and other non-GAAP measures and their calculation.

Although the Company 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 attributing undue certainty or 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.
