Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") today reported unaudited results for the quarter ended March 31, 2023 ("Q1 2023").

"Pan American reported solid results for the first quarter of 2023, with adjusted earnings of $0.10 per share," said Michael Steinmann, President and Chief Executive Officer. "Going forward, Pan American will be a significantly larger, more diversified company following our acquisition of Yamana. Our guidance for 2023 demonstrates the positive impact of the four new mines on production and costs, and we are excited by the growth opportunities the combined portfolio presents."

On March 31, 2023, Pan American completed its previously announced acquisition of all of the issued and outstanding common shares of Yamana Gold Inc. ("Yamana"), following the sale by Yamana of its Canadian assets to Agnico Eagle Mines Limited, by way of a plan of arrangement under the Canada Business Corporations Act (the "Yamana transaction"). The Yamana transaction added four producing mines to Pan American's portfolio: the Jacobina mining complex in Brazil, the El Peñon and Minera Florida mines in Chile, and the Cerro Moro mine in Argentina ("Acquired Operations"), plus several exploration and development projects in Chile, Brazil and Argentina. Operating and financial results reported in this news release, except for the financial position as at March 31, 2023, reflect only Pan American's original mines, specifically: La Colorada, Huaron, San Vicente, Manantial Espejo, Timmins, Shahuindo, La Arena and Dolores (the "Original Assets").

The following highlights for Q1 2023 include certain measures that are not generally accepted accounting principle ("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 Q1 2023 Highlights:

• Silver production of 3.9 million ounces and gold production of 122.7 thousand ounces. As previously disclosed, Manantial Espejo has been placed on care and maintenance following the completion of mining at the end of 2022; some residual production was recorded for Q1 2023.
• Revenue was $390.3 million, inclusive of a negative $3.8 million price adjustment on open concentrate shipments.
• Net earnings of $16.5 million ($0.08 basic earnings per share), including $18.9 million in transaction and integration costs related to the Yamana transaction and $12.7 million in severance provisions. Adjusted earnings were $21.2 million ($0.10 basic adjusted earnings per share).
• Cash flow from operations of $51.3 million, net of $30.7 million in tax payments.
• Silver Segment Cash Costs and All-in Sustaining Costs ("AISC") per silver ounce of $12.19 and $14.13, respectively. Excluding Net Realizable Value ("NRV") inventory adjustments, Silver Segment AISC was $14.11 per ounce.
• Gold Segment Cash Costs and AISC per gold ounce of $1,120 and $1,196, respectively. Excluding NRV inventory adjustments, Gold Segment AISC was $1,361 per ounce.
• Pan American's financial position as at March 31, 2023, incorporates the assets and liabilities Pan American assumed through the Yamana transaction. As at March 31, 2023, Pan American had working capital of $826.6 million, inclusive of cash and short-term investment balances of $513.1 million ($204.7 million related to the Minera Agua Rica Alumbrera ("MARA") project in Argentina), as well as $425 million available under its $750 million revolving sustainability-linked credit facility ("SL-Credit Facility"). Total debt of $1,187.0 million relates to the SL-Credit Facility, construction loans and leases, and two senior notes Pan American assumed through the Yamana transaction: $500 million with a coupon of 2.63% maturing in 2031 and $283 million with a coupon of 4.625% maturing in 2027. Moody's Investors Service and S&P Global have assigned Pan American with an investment grade credit rating.
• A cash dividend of $0.10 per common share with respect to Q1 2023 was previously declared on March 24, 2023, payable on or about May 12, 2023, to holders of record of Pan American’s common shares as of the close of markets on April 14, 2023. The dividends are eligible dividends for Canadian income tax purposes. Pan American selected that record and payment date to harmonize its dividend with respect to Q1 2023 with Yamana’s normal course dividend timing for payment of a first quarter dividend. Subsequent dividends to be declared by Pan American are expected to follow Pan American's previous schedule of dividend payments.
• Two ILO 169 consultation meetings for the Escobal mine were held in Q1 2023, as well as several working meetings between Guatemala's Ministry of Energy and Mines and Xinka Indigenous community representatives. At this time, no date has been set for a potential restart of operations at Escobal.

2023 GUIDANCE

The following provides Management's 2023 guidance, as at May 10, 2023. Relative to the guidance provided on April 27, 2023, the only revision is an increase in estimated project capital expenditures to a range of $95 million to $105 million from the previous range of $75 million to $85 million. The revised range reflects an updated estimate to complete the preliminary economic assessment studies and to advance the exploration drilling for the La Colorada Skarn project.

2023 General and Administrative, Care and Maintenance, and Exploration Expense Forecast

2023 General and Administrative expenses are estimated to total between $75 to $80 million, and reflects increased personnel following the Yamana transaction, increased regulatory and insurance costs, and a normalized year of stock based compensation, which was lower than assumed in 2022 due to share price performance.

2023 Care and Maintenance costs are estimated to total $98 to $109 million, which reflects expenditures for Escobal, the MARA project, Manantial Espejo and Morococha.

2023 Exploration Expense is estimated to total $14 to $16 million for regional greenfield expenditures. The expenditures relating to near-mine exploration are included in the sustaining and project capital amounts provided in the Capital Expenditures Forecast table below.

The production and cost guidance provided in the following tables reflect the contribution from the Acquired Operations for the nine-month period from March 31, 2023 to December 31, 2023, and the full 12-month period of 2023 for Pan American's Original Assets. Please see our MD&A for the period ending March 31, 2023, for a more detailed breakdown of the guidance, including by individual mine and on a quarterly basis for 2023. These estimates are forward-looking statements and information that are subject to the cautionary note associated with forward-looking statements and information at the end of this news release.

(1) 2023 production and AISC forecasts reflect ownership of the Acquired Operations for the nine-month period from March 31 to December 31, 2023 and the full 12 months for Pan American's Original Assets.

(2) Cash Costs and AISC are non-GAAP measures. Please refer to the "Alternative Performance (non-GAAP) Measures" section of this news release for further information on these measures.

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 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 ("AISC"). 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: long-term debt, finance lease liabilities and loans payable. 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 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.

Readers should refer to the "Alternative Performance (non-GAAP) Measures" section of Pan American’s Management's Discussion and Analysis for the period ended December 31, 2022, for a more detailed discussion of these and other non-GAAP measures and their calculation.
