Alamos Gold Reports Second Quarter 2026 Results

Toronto, Ontario ( July 29, 202 6) - Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today

reported its financial results for the quarter ended June 30, 2026.

“We produced 130,600 ounces in the second quarter, meeting our revised quarterly guidance, and up 5% from the

first quarter. The Island Gold District had a solid quarter from multiple perspectives, including delivering record

underground mining rates, milling rates and production. This offset lower than expected production from Mulatos

and Young -Davidson. As previously disclosed, we are expecting lower mining rates at Young -Davidson in the

second half of 2026 resulting in a temporary reduction in production and increase in costs. We have revised our full

year consolidated production and cost guidance with lower production from Young -Davidson the primary driver,”

said John A. McCluskey, President and Chief Executive Officer.

“We expect stronger production and significantly lower costs in 2027 driven by improved results from Young -

Davidson, as well as low -cost growth from the Island Gold District. In addition to performing well operationally, work

on the shaft and mill expansion at the Island Gold District is progressing well with both expected to be key drivers of

growing production and declining costs over the next several years,” Mr. McCluskey added.

Second Quarter 2026 Operational and Financial Highlights

• Produced 130,600 ounces of gold in the second quarter of 2026, in-line with the revised quarterly guidance

of 130,000 to 135,000 ounces, and a 5% increase from the first quarter. The increase was driven by a

strong performance from the Island Gold District, offsetting lower than expected production from the

Mulatos District, as well as Young -Davidson which was impacted by a seismic event in June, as previously

disclosed

• Island Gold District continues to perform well, with underground mining rates increasing to average a record

1,550 tonnes per day ("tpd"). Magino milling rates also increased to average a new record of nearly 8,900

tpd for the quarter, including 9,800 tpd in June. The higher underground mining rates and milling rates drove

record quarterly production of 67,500 ounces. The operation remains on track to achieve its original full year

production guidance with a further increase in underground mining rates and grades expected to drive

growing production through the rest of 2026

• Consolidated production is expected to increase in the second half of 2026; however, given lower expected

mining rates and grades at Young -Davidson, due to the impact of the seismic event, as well as timing of

recovery of ounces at La Yaqui Grande, full year production guidance has been lowered to a range of

510,000 to 560,000 ounces

• Given the lower production, higher costs at Young -Davidson to complete rehabilitation work and enhanced

ground support in the second half of 2026, as well as increased labour inflation and contractor costs in

Canada, full year total cash cost 1 guidance has been increased to a range of $1,175 to $1,275 per ounce,

and all-in sustaining costs ("AISC"1) to between $1,775 and $1,875 per ounce

• Second quarter gold sales totaled 130,834 ounces at an average realized price of $4,504 per ounce,

generating quarterly revenues of $594.1 million, including silver sales. This represented a 36% increase

from the second quarter of 2025

• Cash flow from operating activities in the second quarter was $231.8 million (including $286.9 million before

changes in working capital and taxes paid1, or $0.68 per share)

• Generated strong free cash flow 1 of $143.5 million in the second quarter, while continuing to invest in high -

return growth

• Cost of sales were $231.9 million, or $1,772 per ounce in the second quarter. Total cash costs of $1,303 per

ounce were 6% higher than the first quarter, and AISC of $1,728 per ounce were 7% lower than the first

quarter, largely driven by timing of sustaining capital spend

• Reported net earnings were $270.4 million for the second quarter, or $0.64 per share. Adjusted net

earnings1 were $247.6 million, or $0.59 per share1. Adjusted net earnings include an after-tax adjustment for

net gain on commodity hedge derivatives of $ 27.4 million, an inventory net realizable value adjustment of

$7.0 million, net of tax, adjustments for net unrealized foreign exchange gains recorded within deferred

taxes and foreign exchange totaling $3.6 million, and other adjustments of $1.2 million

• Cash and cash equivalents totaled $636.9 million at June 30, 2026 , down slightly from the first quarter

reflecting increased share repurchases and the elimination of the remaining 2026 legacy gold hedges

inherited from Argonaut Gold ("Argonaut"). The Company remains well -positioned to internally fund all of its

growth initiatives and increased shareholder returns with strong ongoing free cash flow

• Returned $67 million to shareholders during the second quarter. This included the repurchase of 1,401,100

shares at a cost of $50 million ($35.70 per share), and a dividend payment of $17 million (quarterly $0.04

per share)

• Repurchased and eliminated all remaining 2026 legacy gold hedges from Argonaut that were scheduled to

mature in the second half of 2026, providing further upside to higher gold prices. These contracts totaled

35,000 ounces at an average price of $1,821 per ounce. The Company utilized existing cash to eliminate

the hedges at a cost of $92.3 million for an effective price of approximately $4,458 per ounce. The

Company has now retired 279,000 ounces, or 85%, of the 329,000 ounces of forward contracts inherited

from Argonaut, prior to maturity

• Advanced construction of the Company's key growth projects including Lynn Lake, PDA and the expansion

at the Island Gold District. The Phase 3+ Shaft and IGD Expansions are both progressing well with the shaft

expected to be commissioned in the first quarter of 2027, and the Magino mill expansion on track for

completion in the first quarter of 2028

• Provided an exploration update at the Island Gold District with high -grade mineralization extended across

multiple areas which are being targeted as sources of additional higher -grade mill feed within the expanded

Magino mill. This includes defining a new zone of high -grade mineralization 250 metres (“m”) west of

underground Mineral Reserves and Mineral Resources (Island Gold West Extension), as well as continuing

to extend high -grade mineralization within the Island West up -plunge area and the past producing Cline -

Pick and Edwards mines. These targets represent opportunities for further production growth by increasing

the proportion of higher-grade ore to be fed within the expanded Magino mill

all-in sustaining costs at individual mine sites the Company allocates a portion of share based compensation to the mine sites, b ut does not include an allocation of

corporate and administrative expenses to the mine sites.

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

(5) Previous annual guidance was issued on February 4, 2026 and was revised on July 29, 2026.

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.

Second quarter production of 130,600 ounces increased 5% from the first quarter, and was in line with revised

quarterly guidance with a strong performance from the Island Gold District offsetting lower production from Young -

Davidson and the Mulatos District. Production guidance for the second quarter was revised in June reflecting the

impact of a seismic event at Young-Davidson, and delayed recovery of ounces stacked on the leach pad at La Yaqui

Grande. The seismic event at Young -Davidson impacted access to the 9410 level and higher -grade stopes that

were supplying approximately 2,500 tpd of ore. As previously disclosed, this is expected to limit mining rates to an

average of approximately 5,000 tpd in the second half of 2026. Reflecting the lower expected mining rates and

grades at Young -Davidson in the second half of 2026, and longer leach cycle at La Yaqui Grande, full year

production guidance has been lowered to between 510,000 and 560,000 ounces.

Given the lower production, higher costs at Young -Davidson to complete rehabilitation work and enhanced ground

support in the second half of 2026, as well as increased labour inflation and contractor costs in Canada, full year

total cash cost guidance has been increased to a range of $1,175 to $1,275 per ounce, and AISC to between

$1,775 and $1,875 per ounce.

The Company expects stronger production into the second half of the year driven by the ongoing ramp up of

production from the Island Gold District. Production in the third quarter is expected to be between 1 15,000 and

140,000 ounces . AISC are expected to increase in the third quarter reflecting lower production and timing of

sustaining capital. Production is expected to increase in the fourth quarter contributing to lower AISC.

The Island Gold District continues to perform well with a record operational performance from a number of

perspectives in the second quarter. This included underground mining rates of 1,550 tpd and Magino milling rates

increasing to a new high of nearly 8,900 tpd, including averaging approximately 9,800 tpd in June. This drove record

quarterly production of 67,500 ounces. A further increase in underground mining and milling rates, as well as higher

underground grades is expected to drive additional production growth through the second half of the year.

TRADING SYMBOL: TSX:AGI NYSE:AGI

The Company continues to generate strong ongoing free cash flow while advancing its portfolio of high -return

growth projects which are expected to support further production growth and lower costs over the next several

years. Free cash flow totaled $143.5 million in the second quarter, net of a significant reinvestment in growth and

exploration, and supporting the Company's other capital allocation priorities. This included repurchasing $50 million

of shares during the second quarter, and eliminating all remaining legacy Argonaut hedges that were maturing in the

second half of 2026 at a cost of $92.3 million.

Each of the Company's key growth projects are progressing well including the Island Gold District shaft and mill

expansion, PDA and Lynn Lake. These projects are expected to double gold production to approximately one million

ounces annually by 2030, underpinning one of the strongest outlooks in the sector.

The Island Gold District will be a key driver of this growth over the next several years. Following the completion of

the shaft sinking to its planned depth of 1,381 m in the first quarter, shaft equipping and work on the shaft bottom

infrastructure is well underway and expected to continue through 2026. The commissioning of the shaft in the first

quarter of 2027 is expected to support a further increase in underground mining rates. This is expected to drive

consolidated gold production higher and costs lower in 2027.

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

roofing on the new mill building complete, and all eight leach tanks erected. The completion of the IGD Expansion in

2028 is expected to drive a further increase in production and decrease in costs.

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.

Capital spending in 2026 is expected to range between $885 and $975 million, excluding capitalized exploration of

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

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. A further decrease is expected

in 2028 with the completion of the IGD Expansion. A more significant decrease is expected into 2029 and 2030 with

the completion of construction at Lynn Lake.

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

cash flow, $636.9 million of cash and cash equivalents at the end of the second quarter of 2026, and approximately

$1.2 billion of total liquidity. At current gold prices, the Company expects significant free cash flow growth starting in

2027 with the completion of the Phase 3+ Shaft Expansion. The Company remains focused on delivering increasing

shareholder returns with $83.6 million distributed thus far in 2026 through dividends and share buybacks. This

included a 60% increase in the quarterly dividend rate in the first quarter, and the repurchase of $50 million of

shares during the second quarter.

Given the Company's strong outlook with significant free cash flow growth expected over the next several years, the

Company will continue to evaluate opportunities to be active on its share buyback while balancing its other capital

allocation priorities, including the repurchase of the remaining 50,000 ounces of legacy Argonaut hedges set to

mature in 2027.
