2023 Guidance and 5-Year Outlook

2023 Guidance

Osisko expects GEOs earned to range between 95,000 to 105,000 GEOs in 2023 at an average cash margin of 93%.

Osisko's 2023 guidance on royalty and stream interests is largely based on publicly available forecasts from our operating partners. When publicly available forecasts on properties are not available, Osisko obtains internal forecasts from the producers or uses management's best estimate.

For the 2023 guidance, deliveries of silver, diamond, copper, and cash royalties have been converted to GEOs using commodity prices based on consensus prices and a gold/silver price ratio of 80:1. The 2023 guidance also forecasts the closing of the CSA Silver Stream in the second quarter of 2023, with an effective date of February 1, 2023.

5-Year Outlook³

Osisko expects its portfolio to generate between 130,000 and 140,000 GEOs in 2027. The outlook assumes the commencement of production at the San Antonio, Cariboo, Windfall and Back Forty projects. It also assumes that Mantos Blancos will have reached its nameplate capacity following the recent expansion of its activities, as well as increased production from certain other operators that have announced planned expansions. Further, the outlook assumes that production from the Renard diamond stream will have ceased by 2027 (while there remain opportunities for mine life extensions under study by the operator), but such GEOs are expected to be largely replaced by initial production from other assets.

Beyond this growth profile, Osisko owns several other growth assets, which have not been factored in the 5-year outlook, as their timelines are either later, or less clear. As the operators provide further clarity on these assets, Osisko will seek to include them in its long-term outlook.

This 5-year outlook is based on publicly available forecasts and other disclosure by the third-party owners and operators of the Company's assets, and could differ materially from actual results. When publicly available forecasts on properties are not available, Osisko obtains internal forecasts from the producers or uses management's best estimate. The commodity price assumptions that were used in the 5-year outlook are based on current long-term consensus and a gold/silver price ratio of 75:1.

Notes:

(1) Gold Equivalent Ounces

GEOs are calculated on a quarterly basis and include royalties, streams and offtakes. 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. Offtake agreements are converted using the financial settlement equivalent divided by the average gold price for the period.

Average Metal Prices and Exchange 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 (i) cash margin (in dollars and in percentage), (ii) adjusted earnings (loss) and (iii) adjusted earnings (loss) per share. 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 and adjusted earnings 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 and in percentage of revenues)

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

Adjusted earnings (loss) and adjusted earnings (loss) per basic share

Adjusted earnings (loss) is defined as: net earnings (loss) adjusted for certain items: foreign exchange gain (loss), impairment of assets (including impairment on financial assets and investments in associates), gains (losses) on disposal of assets, unrealized gain (loss) on investments, share of income (loss) of associates, deferred income tax expense (recovery), transaction costs and other items such as non-cash gains (losses).

Adjusted earnings (loss) per basic share is obtained from the adjusted earnings (loss) divided by the weighted average number of common shares outstanding for the period.

(3) 5-year Outlook

The 5-year outlook presented in this press release replaces the 5-year outlook previously released in 2022. Investors should not use this 5-year outlook to extrapolate forecast results to any year within the 5-year period (2023-2027).
