Guidance for 2025 and 5-Year Outlook

2025 Guidance

Osisko expects GEOs earned to range between 80,000-88,000 in 2025 at an average cash margin 2 of

approximately 97%. For the 2025 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 2025 guidance assumes Capstone Copper Corp.’s Mantos Blancos mine will continue to operate at its

Phase I nameplate throughput capacity of 20,000 tonnes per day, as well as the commencement of

payments associated with GEOs earned from Cardinal Namdini Mining Limited’s Namdini mine in the

second half of 2025. In addition, the guidance assumes a full year of GEOs earned from the copper stream

from MAC Copper’s CSA mine, and the NSR royalty on G Mining’s Tocantinzinho mine.

Osisko’s 2025 guidance on royalty and stream interests is largely based on publicly available forecasts

from its 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 Outlook

Osisko expects its portfolio to generate between 110,000-125,000 GEOs in 202 9. The outlook assumes

the commencement of production at Gold Fields Limited’s Windfall project and South32 Limited ’s

Hermosa/Taylor project, amongst others. It also assumes increased production from certain other operators

that are advancing expansions, including Alamos Gold Inc.’s Phase 3+ Expansion at its Island Gold District.

The 5-year outlook assumes there will be no GEO contribution from the Eagle Gold mine which is currently

in receivership.

Beyond this growth profile, Osisko owns several other assets, which have not been factored into the 5-year

outlook, as their development timelines are either longer, or difficult to reasonably forecast at this time. As

these operators provide additional clarity on these respective assets, Osisko will seek to include them in

future long-term outlooks.

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 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 operators 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 80:1.

This 5-year outlook replaces the 5- year outlook previously released in 2024 , 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 (2025-2029).

Management Commentary

Jason Attew, President & CEO of Osisko commented : “2024 was a solid year for Osisko, marked by new

annual records achieved with respect to revenues and cash flows, in addition to the closing of several key

transactions which will positively contribute to Osisko’s current and future cash flows. The Company is well-

positioned to pursue additional accretive growth opportunities with a materially improved balance sheet

after $85 million in repayments against its revolving credit facility in 2024.

After working through a comprehensive portfolio review of Osisko’s royalty and stream assets, with a focus

on the Company’s near-to-medium term growth profile and its associated timelines, our new 2025 guidance

and updated five-year outlook together provide what management believes to be achievable ranges, based

on current information and expectations. Regarding the 2025 GEO delivery guidance, it is worth noting that

the expected year -over-year increase in GEO deliveries considers consensus commodity price

assumptions and ratios, and more specifically the gold- to-copper ratio, which has recently expanded in

gold’s favour. This is important as copper is set to become a more meaningful component of our overall

GEO delivery mix for 2025 and beyond. The 2025 guidance also factors in the timing and cadence of

expected payments from assets transitioning from development to production, where some ramp- ups are

going slower than previously anticipated. As a result, Osisko’s 2025 GEO delivery profile is expected to be

modestly weighted towards the second half of the year.

Finally, and most importantly, Osisko’s expected growth trajectory over the next five years through 2029

remains intact and robust at over 30%, as anticipated mine expansions, and the construction of new key

projects, are all expected to be completed by our operating partners between now and then.”

Notes:

(1) Gold Equivalent Ounces

GEOs are calculated on a quarterly basis and include royalties and streams. Silver ounces and copper tonnes earned from

royalty and stream agreements are converted to gold equivalent ounces by multiplying the silver ounces or copper tonnes by the

average silver price per ounce or copper price per tonne for the period and dividing by the average gold price per ounce for the

period. Diamonds, other metals and cash royalties are converted into gold equivalent ounces by dividing the associated revenue

by the average gold price per ounce for the period.

(2) Non-IFRS Measures

Cash margin (in dollars and in percentage of revenues)

Cash margin in dollars and in percentage of revenues are non-IFRS financial measures. Cash margin (in dollars) is defined by

Osisko as revenues less cost of sales (excluding depletion). Cash margin (in percentage of revenues) is obtained from the cash

margin (in dollars) divided by revenues.

Management uses cash margin in dollars and in percentage of revenues to evaluate Osisko’s ability to generate positive cash

flow from its royalty, stream and other interests. Management and certain investors also use this information, together with

measures determined in accordance with IFRS Accounting Standards such as gross margin and operating cash flows, to evaluate

Osisko’s performance relative to peers in the mining industry who present these measures on a similar basis. Cash margin in

dollars and in percentage of revenues are only intended to provide additional information to investors and analysts and should

not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS Accounting

Standards. They do not have any standardized meaning under IFRS Accounting Standards and may not be comparable to similar

measures presented by other issuers.

Adjusted earnings and adjusted earnings per basic share

Adjusted earnings and adjusted earnings per basic share are non-IFRS financial measures and are defined by Osisko by

excluding the following items from net earnings (loss) and earnings (loss) per share: foreign exchange gains (losses), impairment

charges and reversal related to royalty, stream and other interests, changes in allowance for expected credit losses, write-offs

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.

Management uses adjusted earnings and adjusted earnings per basic share to evaluate the underlying operating performance

of Osisko as a whole for the reporting periods presented, to assist with the planning and forecasting of future operating results,

and to supplement information in its consolidated financial statements. Management believes that in addition to measures

prepared in accordance with IFRS Accounting Standards such as net earnings (loss) and net earnings (loss) per basic share,

investors and analysts use adjusted earnings and adjusted earnings per basic share to evaluate the results of the underlying

business of Osisko, particularly since the excluded items are typically not included in Osisko’s annual guidance. While the

adjustments to net earnings (loss) and net earnings (loss) per basic share in these measures include items that are both recurring

and non-recurring, management believes that adjusted earnings and adjusted net earnings per basic share are useful measures

of Osisko’s performance because they adjust for items which may not relate to or have a disproportionate effect on the period in

which they are recognized, impact the comparability of the core operating results from period to period, are not always reflective

of the underlying operating performance of the business and/or are not necessarily indicative of future operating results. Adjusted

net earnings and adjusted net earnings per basic share are intended to provide additional information to investors and analysts

and should not b e considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS

Accounting Standards. They do not have any standardized meaning under IFRS Accounting Standards and may not be

comparable to similar measures presented by other issuers.

Adjusted earnings per basic share 0.16 0.12 0.52 0.40

During the fourth quarter of 2023, the following changes were made to the composition of adjusted earnings:

(i) total gains and losses on investments on the statement of income (loss) are now excluded from net earnings (loss);

prior to this change, only the unrealized gains and losses on investments were excluded from net earnings (loss);

(ii) total foreign exchange gains and losses on the statement of income (loss) are now excluded from net earnings (loss);

prior to this change, only the foreign exchange gains and losses adjustments from operation activities on the statement

of cash flows were excluded from net earnings (loss);

(iii) the tax impact of all adjustments in the calculation of adjusted earnings is now considered; prior to this change, the

total deferred income taxes on the statement of earnings (loss) was excluded from net earnings (loss).

These changes in the manner in which Osisko calculates adjusted earnings were made to align more closely the calculations with its

peers and facilitate the comparison with these companies. These changes also affected adjusted earnings per basic share because

they are calculated from adjusted earnings. Quarterly comparative figures have been restated to reflect the current composition of

adjusted earnings and adjusted net earnings per basic share.
