Fortuna pays down an additional $41 million of debt

(All amounts expressed in US dollars)

Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to report that the Company has paid down an additional $41 million of its revolving credit facility at the end of the fourth quarter of 2023, using cash on hand.

After the payment of $41 million, the Company expects to bring down the leverage ratio ¹ below 0.5 times total net debt ² to adjusted EBITDA ³ (which was reported for the third quarter of 2023). At December 31, 2023, it is expected that Fortuna's total outstanding debt balance will stand at approximately $165 million on its credit facility (excluding letters of credit), and approximately $46 million of convertible notes, for an estimated total net debt, after cash and cash equivalents, of $83 million as at December 31, 2023. This represents a reduction of approximately $50 million in total net debt in the period, reflecting cash flow contributions from the Séguéla Mine in its second full quarter of production.

The estimated total net debt and liquidity for Fortuna as at the end of the fourth quarter of 2023 is preliminary financial information and has been prepared by management and remains subject to final review by the Company's audit committee and approval by the Company's board of directors. Such preliminary financial information for the fourth quarter of 2023 is subject to the finalization and closing of Fortuna´s accounting books and records for the period and should not be viewed as a substitute for the Company's annual financial statements prepared in accordance with accounting principles generally accepted under International Financial Reporting Standards (IFRS). The Company's auditor has not audited the preliminary financial information contained in this news release, nor have they expressed any opinion or any other form of assurance on the preliminary financial information contained herein.

Non-IFRS Financial Measures

The Company has disclosed certain financial measures and ratios in this news release which are not defined under IFRS, as issued by the International Accounting Standards Board, and are not disclosed in the Company's financial statements, including but not limited to total net debt and total net debt to adjusted EBITDA ratio. These non-IFRS financial measures and non-IFRS ratios are widely reported in the mining industry as benchmarks for performance and are used by management to monitor and evaluate the Company's operating performance and ability to generate cash. The Company believes that, in addition to financial measures and ratios prepared in accordance with IFRS, certain investors use these non-IFRS financial measures and ratios to evaluate the Company's performance. However, the measures do not have a standardized meaning under IFRS and may not be comparable to similar financial measures disclosed by other companies. Accordingly, non-IFRS financial measures and non-IFRS ratios should not be considered in isolation or as a substitute for measures and ratios of the Company's performance prepared in accordance with IFRS. Except as otherwise described below, the Company has calculated these non-IFRS financial measures and non-IFRS ratios consistently for all periods presented. To facilitate a better understanding of these measures as calculated by the Company, descriptions are provided below.

Total net debt is a non-IFRS measure which is calculated as debt consisting of credit facilities and convertible debentures less cash and cash equivalents.

Management believes that total net debt provides valuable information as an indicator of the Company's liquidity and ability to fund working capital needs fund capital expenditures. Total net debt is also a common metric that provides additional information used by investors and analysts for valuation purposes based on an observed or inferred relationship between total net debt and enterprise value. Total net debt is not meant to be a substitute for other subtotals or totals presented in accordance with IFRS measures, but that rather should be evaluated in conjunction with IFRS measures.

The debt, cash and cash equivalents, and total net debt figures for the Company presented in the table above, represent preliminary financial information estimated by management which remains subject to final review by the Company's Auditors, audit committee and approval by the Company's board of directors .
   

Total Net Debt to Adjusted EBITDA Ratio

Total net debt to adjusted EBITDA ratio is a non-IFRS ratio which is calculated as total net debt divided by adjusted EBITDA. Management believes that total net debt to adjusted EBITDA provides valuable information as an indicator of the Company's solvency and ability to fund working capital needs and fund capital expenditures. Total net debt to adjusted EBITDA ratio is also a common metric that provides additional information used by investors and analysts for valuation purposes based on an observed or inferred relationship between total net debt to adjusted EBITDA ratio and enterprise value. Total net debt to adjusted EBITDA ratio is not meant to be a substitute for other subtotals or totals presented in accordance with IFRS measures, but rather should be evaluated in conjunction with IFRS measures.
