Guidance for 2024 and 5-Year Outlook

2024 Guidance³

Osisko expects GEOs earned to range between 82,000 to 92,000 in 2024 at an average cash margin of 97%. The 2024 guidance assumes the commencement of GEOs earned from the CSA Copper Stream from June 15, as well as the commencement of production from G Mining Ventures Corp.'s Tocantinzinho project and Cardinal Namdini Mining Limited's project later in the year.

Osisko's 2024 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.

5-Year Outlook³

Osisko expects its portfolio to generate between 120,000 and 135,000 GEOs in 2028. The outlook assumes the commencement of production at The Windfall Mining Group's Windfall and South32 Ltd's Hermosa, amongst others. It also assumes that Capstone Copper Corp's 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, including Alamos Gold Inc.'s Phase 3+ Expansion at Island Gold.

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 internal judgements of publicly available forecasts and other disclosures by the third-party owners and operators of the Corporation'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.

This 5-year outlook replaces the 5-year outlook previously released in 2023, which should be considered withdrawn. Investors should not use this 5-year outlook to extrapolate forecast results to any year within the 5-year period (2024-2028).

Management Commentary

Jason Attew, President & CEO of Osisko commented: "2023 was a banner year for Osisko marked by new annual records achieved with respect to GEOs earned, revenues, cash flows and margins, in addition to the closing of several key transactions which will positively contribute to Osisko's cash flow and GEOs earned. The Corporation is now well-positioned with a materially improved balance sheet, and also with having completed recent changes as it relates to both management and the Board.

After working through a full portfolio review as it relates to Osisko's growth trajectory and associated timelines, the Corporation's 2024 guidance and updated 5-year outlook together provide what management believes to be achievable ranges. Concerning the 2024 guidance, it is worth noting that the lack of GEO deliveries resulting from the stoppage of operations at the Renard diamond mine will be partially offset by expected improvements at certain other operating assets within our portfolio, in addition to some new assets moving out of development and into production throughout the year. Furthermore, the Corporation's expected growth trajectory over the next five years remains very much intact as mine expansions and new projects are completed by our partners between now and 2028.

Osisko enters 2024 with a continued focus on simplifying its story to further re-establish itself as a 'pure-play' precious metals royalty and streaming company. We possess an unmatched asset base as defined by exposure to Tier 1 mining jurisdictions and this unique aspect of our portfolio, when combined with our robust organic growth outlook, results in the Corporation being well-positioned to deliver long-term value to our current and future shareholders."

Notes:

(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

(2) From continuing operations.

(3) For the 2024 guidance, deliveries of silver, copper, and cash royalties have been converted to GEOs using commodity prices based on consensus prices and a gold/silver price ratio of 83:1. 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 76:1.

(4) Non-IFRS Measures

The Corporation has included certain performance measures in this press release and in the annual Management and Discussion Analysis for the year ended December 31, 2023 that do not have any standardized meaning prescribed by IFRS Accounting Standards including (i) cash margin (in dollars and in percentage of revenues), (ii) adjusted earnings and (iii) adjusted earnings per basic 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 Accounting Standards. These measures are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS Accounting Standards. 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 Accounting Standards, 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.

In 2023, the following changes were made to the composition of adjusted earnings:

These changes in the manner in which the Corporation calculates adjusted earnings were made to align the calculations with its peers and facilitate the comparison with these companies. These changes also affect indirectly adjusted earnings per basic share, because they are calculated from adjusted earnings. Comparative figures for 2022 have been restated to reflect the current composition of adjusted earnings.

Cash Margin (in dollars and in percentage of revenues)

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

Adjusted earnings and adjusted earnings per basic share

Adjusted earnings is defined as: net earnings (loss) from continuing operations, adjusted for certain items: foreign exchange gains (losses), impairment charges and reversal related to royalty, stream and other interests, expected credit losses and impairment of investments, gains (losses) on disposal of assets, gains (losses) on investments, share of income (loss) of associates, transaction costs and other items such as non-cash gains (losses), as well as the impact of income taxes on these items. Adjusted earnings per basic share is obtained from the adjusted earnings divided by the weighted average number of common shares outstanding for the period.
