Fortuna Silver Mines Inc. Announces Pricing of Convertible Senior Notes

The Notes will bear cash interest semi-annually at a rate of 3.75% per annum. The initial conversion rate for the Notes will be 151.7220 common shares of Fortuna ("Shares") per US$1,000 principal amount of Notes, equivalent to an initial conversion price of approximately US$6.59 per Share. The initial conversion rate represents a premium of approximately 30% relative to today's closing sale price of the Shares and is subject to adjustment in certain events.

Fortuna will have the right to redeem the Notes in certain circumstances and holders will have the right to require Fortuna to repurchase their Notes upon the occurrence of certain events.

The Offering is expected to close, subject to customary closing conditions, on or about June 10, 2024.

The Company intends to use the net proceeds from the Offering to repay bank indebtedness, to fund working capital requirements, for general corporate purposes and to fund the repayment of its existing 4.65% senior subordinated unsecured convertible debentures, to the extent that such debentures are not converted into shares prior to the redemption date.

Immediately prior to the closing of the Offering, the Company intends to issue a notice of redemption in respect of the existing debentures. Holders of the existing debentures may choose to convert their debentures prior to the redemption date or receive a cash payment from the debenture trustee.

The Notes and the Shares issuable upon the conversion thereof have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"), or qualified by a prospectus in Canada. The Notes and the Shares may not be offered or sold in the United States absent registration under the Securities Act or an applicable exemption from registration under the Securities Act. The Notes will be offered only to "qualified institutional buyers" (as defined in Rule 144A under the Securities Act) and outside the United States to non-U.S. persons in compliance with Regulation S under the Securities Act. Offers and sales in Canada will be made only pursuant to exemptions from the prospectus requirements of applicable Canadian provincial securities laws.

This news release is neither an offer to sell nor the solicitation of an offer to buy the Notes or any other securities and shall not constitute an offer to sell or solicitation of an offer to buy, or a sale of, the Notes or any other securities in any jurisdiction in which such offer, solicitation or sale is unlawful.
