Q4 AND YEAR-END 2023 RESULTS CONFERENCE AND WEBCAST CALL DETAILS

Osisko provides notice of the fourth quarter and annual 2023 results and conference and webcast call details.

The figures presented in this press release, including revenues and costs of sales, have not been audited and are subject to change. As the Corporation has not yet finished its year-end procedures, the anticipated financial information presented in this press release is preliminary, subject to year-end adjustments, and may change materially.

(1) Gold Equivalent Ounces

GEOs are calculated on a quarterly basis and include royalties and streams. Silver earned from royalty and stream agreements are converted to gold equivalent ounces by multiplying the silver ounces earned by the average silver price for the period and dividing by the average gold price for the period. Diamonds, other metals and cash royalties are converted into gold equivalent ounces by dividing the associated revenue earned by the average gold price for the period.

Average Metal Prices and Exchange Rate

(i) The London Bullion Market Association's pm price in U.S. dollars.
(ii) The London Bullion Market Association's price in U.S. dollars.
(iii) Bank of Canada daily rate.

(2) Non-IFRS Measures

The Corporation has included certain performance measures in this press release that do not have any standardized meaning prescribed by International Financial Reporting Standards (IFRS) including cash margin in dollars and in percentage. The presentation of these non-IFRS measures is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. As Osisko's operations are primarily focused on precious metals, the Corporation presents cash margins as it believes that certain investors use this information, together with measures determined in accordance with IFRS, to evaluate the Corporation's performance in comparison to other companies in the precious metals mining industry who present results on a similar basis. However, other companies may calculate these non-IFRS measures differently.

Cash margin (in dollars) represents revenues less cost of sales (excluding depletion). Cash margin (in percentage) represents the cash margin (in dollars) divided by revenues.
