Alamos Gold Reports First Quarter 2026 Results

Strong margin expansion drives record cash flow from operations and solid ongoing free cash

flow of $102 million

Toronto, Ontario (April 29, 2026) - Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today

reported its financial results for the quarter ended March 31, 2026.

“Our first quarter production was in line with guidance driven by a solid performance from the Island Gold District.

Underground mining rates at Island Gold increased to a new record, and milling rates at Magino increased

significantly over the past six weeks following the implementation of additional improvements. We expect all three of

our operations to contribute to a 20% increase in production in the second quarter, with further growth into the

second half of the year at substantially lower costs driven by the ongoing ramp up of mining rates at Island Gold.

We expect this trend of growing production and declining costs to continue through the end of the decade as we

advance our portfolio of high -return growth projects, underpinning one of the strongest outlooks in the sector,” said

John A. McCluskey, President and Chief Executive Officer.

First Quarter 2026 Operational and Financial Highlights

• Produced 123,900 ounces of gold in the first quarter of 2026, in-line with quarterly guidance with strong results

from the Island Gold District offsetting lower than planned production at Young -Davidson. Production is

expected to increase in the second quarter with further growth in the second half of the year, putting the

Company on track to achieve full year production guidance

• Sold 121,924 ounces of gold at an average realized price of $4,829 per ounce, generating record quarterly

revenues of $596.7 million, including silver sales. This represented a 79% increase from the first quarter of 2025

and marked the fourth consecutive quarter of record revenues

• Cost of sales were $205.5 million, or $1,685 per ounce in the first quarter. Total cash costs1 of $1,230 per ounce

and all -in sustaining costs ("AISC" 1) of $1,862 per ounce for the first quarter were above the top end of

guidance for the first half of 2026, as previously guided. Total cash costs and AISC are expected to decrease in

the second quarter and further into the second half of the year, driven by low -cost growth from the Island Gold

District, and lower costs from Young-Davidson

• First quarter cash flow from operating activities was $242.5 million (including a record $338.0 million before

changes in working capital and taxes paid1, or $0.80 per share)

• Generated strong free cash flow 1 of $101.7 million in the first quarter, while continuing to invest in high return

growth projects, and net of $82.0 million paid in cash taxes

• Reported net earnings were $191.4 million for the first quarter, or $0.46 per share. Adjusted net earnings 1 were

$232.0 million, or $0.55 per share1. Adjusted earnings include after-tax adjustment for net loss es on commodity

hedge derivatives of $ 20.2 million, adjustments for net unrealized foreign exchange losses recorded within

deferred taxes and foreign exchange totaling $19.3 million, and other adjustments of $1.1 million

• Cash and cash equivalents increased to $659.5 million at March 31, 2026, up from $623.1 million at the end of

2025. This reflected strong ongoing free cash flow while funding high -return growth, increased shareholder

returns, and $42.7 million used to retire additional legacy gold hedges. The Company remains well -positioned to

internally fund all of its growth initiatives with strong ongoing free cash flow, net cash of $459.5 million, and

approximately $1.2 billion of total liquidity

• Announced a 60% increase in the quarterly dividend rate to $0.04 per share, with $16.6 million paid in the first

quarter

• Repurchased and eliminated approximately one -third of legacy gold hedges from Argonaut Gold Inc.

("Argonaut") that were scheduled to mature in the second half of 2026, providing further upside to higher gold

prices. These contracts totaled 15,000 ounces at an average price of $1,821 per ounce. The Company utilized

existing cash to eliminate the hedges at a cost of $42.7 million for an effective price of approximately $4,667 per

ounce

• Announced the IGD Expansion Study on February 3, 2026, outlining a long -life operation that is expected to

become one of the largest, lowest -cost, and most profitable gold mines in Canada with annual production

expected to increase to average 534,000 ounces over the initial 10 years (starting in 2028) at average mine -site

AISC of $1,025 per ounce. At a gold price of $4,500 per ounce and USD/CAD foreign exchange rate of $0.74:1,

the Island Gold District has an estimated after -tax net present value ("NPV") (5%) of $12.2 billion, making it one

of the most valuable gold mines in Canada. The IGD Expansion is progressing well and remains on track for

completion in 2028

• Advanced the Phase 3+ Shaft Expansion at the Island Gold District. This included completing the shaft sink and

advancing construction of the paste plant and administrative complex. Construction of the shaft and surface

infrastructure is expected to be substantially complete by the end of 2026, and commissioning of the shaft

completed in early 2027

• Reported year-end 2025 Mineral Reserves of 15.9 million ounces (265 million tonnes ("mt")), a 32% increase

from the end of 2024, with grades also increasing 5% to 1.87 grams per tonne (“g/t Au”). This marked the

seventh consecutive year Mineral Reserves have increased for a cumulative increase of 64%, with grades also

increasing 24% over that time frame

(2) Cost of sales includes mining and processing costs, royalties, and amortization expense but excludes silver credit, and is ca lculated based on the mid-point of total

cash cost guidance.

(3) For the purposes of calculating mine -site all-in sustaining costs at individual mine sites the Company allocates a portion of share based compensation to the mine

sites, but does not include an allocation of corporate and administrative expenses to the mine sites.

(4) Sustaining and growth capital guidance excludes capitalized exploration.

The Company’s objective is to operate a sustainable business model that supports growing returns to all

stakeholders over the long -term, through growing production, expanding margins, and increasing profitability. This

includes a balanced approach to capital allocation focused on generating strong ongoing free cash flow while re -

investing in high-return internal growth opportunities, and supporting higher returns to shareholders.

During the first quarter, the Company delivered on these objectives across multiple fronts, including meeting

quarterly guidance while continuing to advance its high -return growth projects. First quarter production of 123,900

ounces was in line with guidance with a strong performance from the Island Gold District more than offsetting lower

production from Young-Davidson. As previously guided, total cash costs and AISC were above first half guidance,

with both expected to decrease in the second quarter and more significantly in the second half of the year.

Reflecting strong ongoing margins, the Company generated $101.7 million of free cash flow in the first quarter while

funding its peer leading pipeline of growth projects, and net of $82.0 million of cash taxes paid. Higher production,

lower costs and lower cash taxes are expected to drive stronger free cash flow through the remainder of year.

Underground mining rates at Island Gold increased to average a new record of over 1,400 tpd during the first

quarter, while the addition of the supplementary crushed ore feed in the second half of February and other

operational improvements supported the ramp up of processing rates in the Magino mill to average 9, 200 tpd over

the past six weeks. The ramp up of underground mining rates is expected to continue through the year supporting

growing production from the Island Gold District.

All three operations are expected to contribute to a substantial growth in the second quarter with production

expected to increase to between 145,000 and 155,000 ounces. With stronger production expected into the second

half of the year, the Company remains on track to achieve full year guidance. Reflecting the stronger production,

AISC are expected to decrease approximately 5% in the second quarter with a more significant improvement into

the second half of the year. The Company continues to monitor the impact of ongoing inflationary pressures across

its cost structure. This includes higher labour, contractor, diesel, electricity and natural gas costs, and the

downstream impact of higher energy prices on other consumables. The Company expects to manage these cost

pressures with productivity improvements through the year driving costs lower and significant margin expansion at

current gold prices.

This trend of growing production and declining costs is expected to continue through the end of the decade driven

by the Company's portfolio of high -return and low -cost growth projects. This includes the Island Gold District shaft

and mill expansion, PDA and Lynn Lake, all of which continued to advance during the first quarter. These projects

are expected to nearly double gold production to approximately one million ounces annually by 2030, underpinning

one of the strongest outlooks in the sector.

TRADING SYMBOL: TSX:AGI NYSE:AGI

The Island Gold District will be a key driver of this growth over the next several years. The Phase 3+ Shaft

Expansion achieved a significant milestone during the first quarter with the completion of the shaft sink to its

planned depth of 1,381 metres ("m"). Work on the shaft bottom infrastructure will continue through 2026 with

commissioning of the shaft expected to be completed early in 2027. This is expected to drive consolidated gold

production to a range of between 650,000 and 730,000 ounces in 2027, a 13% increase from 2026.

In parallel, work on the Magino mill expansion to 20,000 tpd continues to progress with construction and exterior

cladding of the new mill building well underway. The completion of the IGD Expansion in 2028 is expected to

support a further increase in production to a range of 755,000 to 835,000 ounces, representing a 15% increase from

2027 and cumulative 46% increase from 2025.

Further growth is expected into 2029 with initial production from Lynn Lake, and the ramp up of underground mining

rates at Island Gold to 3,000 tpd, as outlined in the IGD Expansion Study. By 2030, production is expected to

increase to a rate of approximately one million ounces annually.

Total cash costs and AISC in 2027 are expected to decrease 19% and 10%, respectively, from 2025 driven by low -

cost growth from the Island Gold District with the completion of the shaft and connecting the Magino mill to low -cost

grid power. A further decrease in costs is expected into 2028 with AISC expected to be between $1,200 and $1,300

per ounce, representing an 18% decrease from 2025. This is expected to be driven by the first full year of

production from PDA in Mexico and a further increase in low -cost production from the Island Gold District with the

completion of the IGD Expansion. Costs are expected to continue decreasing into 2029 and 2030 with the ramp up

of underground mining rates at Island Gold to 3,000 tpd, and the start of production from the low -cost Lynn Lake

project.

Capital spending in 2026 is expected to range between $850 and $940 million, excluding capitalized exploration of

$60 million. The largest portion of this budget will be focused on the completion of the shaft expansion and larger

mill expansion within the Island Gold District. Capital spending is expected to decline slightly in 2027 with increased

spending at Lynn Lake offset by lower spending on PDA and the Island Gold District. In 2028, capital spending is

expected to decrease approximately 24% compared to 2027 as the IGD Expansion is completed. A more significant

decrease is expected into 2029 and 2030 with the completion of construction at Lynn Lake.

A record $97 million has been budgeted globally for exploration in 2026, a 37% increase from the $71 million spent

in 2025. The increase reflects significant ongoing exploration success, including a 32% increase in Global Mineral

Reserves to 15.9 million ounces in 2025, with grades also increasing 5% to 1.87 g/t Au (265 mt). This includes

expanded budgets at each of the Island Gold District, Young -Davidson and Lynn Lake. The Island Gold District

remains the largest portion of the budget with $43 million planned for 2026, following up on another year of

substantial Mineral Reserve growth.

The Company remains well positioned to fund its high -return growth projects internally with strong ongoing free

cash flow, $659.5 million of cash and cash equivalents at the end of the first quarter of 2026, and approximately

$1.2 billion of total liquidity. At current gold prices, the Company expects to continue generating strong free cash

flow while funding its growth projects, with significant increases starting in 2027 with the completion of the Phase 3+

Shaft Expansion. The Company also remains focused on shareholder returns. Given the strong ongoing free cash

flow, and significant growth expected over the next several years, the Company increased its quarterly dividend rate

by 60% to $0.04 per share in the first quarter, and will continue to assess opportunities to be active on its share

buyback.
