TSX: IMG NYSE: IAG NEWS RELEASE

IAMGOLD REPORTS FOURTH QUARTER AND YEAR-END 2023 RESULTS;

PROVIDES 2024 OUTLOOK

All monetary amounts are expressed in U.S. dollars, unless otherwise indicated.

Toronto, Ontario, February 1 5, 2024 – IAMGOLD Corporation (NYSE:IAG, TSX:IMG) (“IAMGOLD” or the “Company”)

today reported its financial and operating results for the fourth quarter and year ended December 31, 2023. The Company

also provided updated outlook and operating guidance for 2024. Preliminary operating results for the fourth quarter and

year ended 2023 were disclosed on January 22, 2024.

"In 2023, IAMGOLD made significant strides towards its goal of becoming a leading mid -tier gold producer with a long life,

cornerstone asset in Canada," said Renaud Adams, President and Chief Executive Officer of IAMGOLD. "Last year saw

significant changes in leadership across the organization to allow for a reinforced focus on operations as IAMGOLD

prioritizes operational excellence, positions Côté Gold for success, and fosters the talent within the company. Operationally,

2023 was a strong year with attri butable gold production from continuing operations of 465,000 ounces, which was at the

top end of the guidance range of 410,000 to 470,000 ounces. We congratulate the Essakane team who achieved their

targets while facing considerable challenges within the region, and the Westwood team who continue to execute on the plan

to ramp up underground operations while employing industry-leading underground seismic monitoring and management."

"Côté Gold construction saw remarkable progress last year," continued Mr. Adams. "The project entered 2023 with

construction approximately 64% complete and finished the year at 98% complete. This progress entailed significant

advancement across the project scope, including the mechanical, piping, electrical and instrumentation of the plant,

electrification of the site to the provincial hydro grid, initiation and ramp up of mining activities and continued heavy lifting to

raise the tailings management facili ty. Mining activities advanced very well through the year with the successful roll out of

Ontario’s first autonomous haulage fleet and stockpiling of approximately 5 million tonnes of ore. During this period, project

costs tracked in line with the 2022 updated budget estimate."

"Côté Gold is poised to begin production next month. While first gold is on the horizon, our primary focus and efforts are on

positioning the project for a steady ramp up of gold production through the year to achieve commercial production in the

third quarter. We are now executing and ramping up commissioning activities, with crushing and screening successfully

commissioned, and pre-commissioning ongoing on the HPGR and wet side of the plant. At steady run -rate, Côté Gold will

be the third largest gold min e in Canada with an expected mine life exceeding 18 years and significant opportunities for

growth."

HIGHLIGHTS:

Operating and Financial

• Attributable gold production from continuing operations was 136,000 ounces for the fourth quarter and 465,000 ounces

with attributable production of 108,000 ounces and year to date attributable production of 372,000 ounces, which was

near the top end of the guidance range of 340,000 to 380,000 ounces. Westwood exceeded the top end of its guidance

range of 70,000 to 90,000 ounces with 93,000 ounces produced for the year, including 12,400 ounces produced in

December, a record since the mine restarted.

• In health and safety, for the year ended December 31, 2023, the Company reported a TRIFR (total recordable injuries

frequency rate) of 0.69, an improved trend since last year.

• Revenues from continuing operations were $297.6 million in the fourth quarter from sales of 147,000 ounces (136,000

ounces on an attributable basis) at an average realized gold price 1 of $2,005 per ounce and $987.1 million for the year

from sales of 503,000 ounces (462,000 ounces on an attributable basis) at an average realized gold price of $1,955

per ounce.

• Cost of sales per ounce sold in the fourth quarter was $1,201, cash cost 1 per ounce sold was $1,197 and all -in-

sustaining-cost1 (“AISC”) per ounce sold was $1,735. Cash cost per ounce sold of $1,261 for the year was at the bottom

end of the revised guidance range of $1,250 to $1,325 per ounce sold, and AISC per ounce sold of $1,783 for 2023

was within the revised guidance range of $1,750 to $1,825 per ounce sold.

• Net earnings (loss) and adjusted net earnings (loss) per share attributable to equity holders 1 of $(0.02) and $0.06 for

the fourth quarter, respectively. Net earnings (loss) and adjusted net earnings (loss) per share attributable to equity

holders1 of $0.18 and $0.09 for the year ended December 31, 2023, respectively.

operating activities, before movements in non -cash working capital and non -current ore stockpiles 1 was $52.1 million

for the fourth quarter and $158.9 million for the year.

• Earnings before interest, income taxes, depreciation and amortization (“EBITDA”) 1 from continuing operations was

$70.2 million during the fourth quarter and $366.6 million for the year, and adjusted EBITDA1 was $110.6 million for the

fourth quarter and $315.1 million for the year.

• Mine-site free cash flow 1 from continuing operations was $28.9 million for the fourth quarter and $48.2 million for the

year.

• The Company has available liquidity 1 of $754.1 million comprised of cash and cash equivalents of $367.1 million and

the available balance of the secured revolving credit facility (“Credit Facility”) of $387.0 million as at December 31, 2023.

Côté Gold

• As of December 31, 2023, construction progress at Côté Gold was estimated to be 98% complete, while overall project

progress was approximately 95.5% complete which includes demobilization of construction teams and facilities.

• On a 100% basis at the UJV level, the Côté Gold Project incurred project expenditures1 of $242.9 million ($170.5 million

at 70%) in the fourth quarter 2023 and $1,074.2 million ($752.3 million at 70%) for the full year.

• Since commencement of construction, $2.786 billion ($1.95 billion at 70%) of project expenditures has been incurred.

The estimated remaining project expenditures, on a 100% basis, to achieve first gold is $179.0 million (± 5%) bringing

total project expend itures up to first gold in line with the planned $2.965 billion ($2.08 billion at 70%) on an incurred

basis. Post first gold, completion of certain infrastructure and earthworks projects are estimated to $40 million (± 5%).

• In addition to the project expenditures, an estimated $40 million (± 5%) of operating expenditures related to milling and

surface costs are expected to be capitalized during commissioning and ramp -up until the project achieves commercial

production.

• Production at Côté Gold, on a 100% basis, is expected to be between 220,000 and 290,000 ounces for the year. This

estimate assumes that following initial gold production by the end of March, operations ramp -up in the second quarter

2024 and commercial production is achieved in the third quarter 2024. The Company expects Côté Gold operations to

exit the year at a throughput rate of approximately 90% of nameplate.

• As Côté Gold achieves 90% of throughput, which is expected by the end of the year, the Company estimates cash costs

at that time to be in the range of approximately $700 to $800 per ounce sold and AISC of $1,100 to $1,200 per ounce

sold.

• The estimated capital expenditures related to operations for 2024, excluding capital waste stripping, total $145 million

(± 5%). Capitalized waste stripping is estimated to be $50 million (± 5%) for the year.

• IAMGOLD will continue to fund 60.3% of the operating costs and capital expenditures and will receive 60.3% of the

gold production.

Outlook – Essakane and Westwood

• Consolidated 2024 attributable gold production for Essakane and Westwood is expected to be in the range of 430,000

to 490,000 ounces, with Essakane attributable gold production expected to be in the range of 330,000 to 370,000

ounces and Westwood gold production expected to be in the range of 100,000 to 120,000 ounces.

• Cash costs, excluding Côté Gold, are expected to be between $1,280 and $1,400 per ounce sold, and AISC per ounce

sold, excluding Côté Gold, is expected to be in the range of $1,780 to $1,940 per ounce sold.

OUTLOOK

Côté Gold (100% basis)

Production

Production at Côté Gold is expected to be between 220,000 and 290,000 ounces for the year. This estimate assumes that

following initial gold production, operations ramp-up early in the second quarter 2024 and commercial production is achieved

in the third quarter 2024. The Company defines commercial production as an average throughput of the mill of 60% over a

period of 30 days. The Company expects Côté Gold operations to exit the year at a throughput rate of approximately 90%

of nameplate.

Costs

During the ramp up period and prior to achieving near nameplate production rates, operating and capitalized waste stripping

unit costs are expected to be higher than the expected life of mine average as outlined in the existing 43 -101 technical

report (dated August 12, 2022) as fixed costs are absorbed by lower volumes, increases in certain cost inputs from the

impact of inflation since completion of the technical report, and higher royalty costs due to higher gold prices. As Côté Gold

achieves 90% throughput, which is expected by the end of the year, the Company estimates cash costs at that time to be

in the range of approximately $700 to $80 0 per ounce sold and AISC of $1,100 to $1,200 per ounce sold. For accounting

purposes, revenue and cost of sales will be recognized from the commencement of production.

Capital Expenditures

The estimated remaining project expenditures to achieve first gold is $179.0 (± 5%) bringing the total project expenditures

up to first gold to $2.965 billion on an incurred basis. Post first gold, completion of certain infrastructure and earthworks

projects are estimated to be $40 million (± 5%).

In addition to the project expenditures, an estimated $40.0 million (± 5%) of operating expenditures related to milling and

surface costs are expected to be capitalized during commissioning and ramp until the project achieves commercial

production.

The estimated capital expenditures related to operations for 2024, excluding capital waste stripping, total $145 million (±

5%). These expenditures will be incurred from January to December and include:

• $60 million (± 5%) for the expansion of the tailings management facility as part of phase 2.

• $50 million (± 5%) for equipment purchases that includes four additional haulage trucks, drills and other mobile

equipment.

• $35 million (± 5%) for capital projects that includes owners' costs.

Capitalized waste stripping is estimated to be $50 million (± 5%) for the year.

Côté Gold's capital expenditures in 2024 are expected to be higher than the life -of-mine average as the mine progresses

the completion of the construction of the full tailings dam footprint to support the life of mine. The classification of capi tal

expenditures as either sustaining or expansion during 2024 will be dependent on the timing of achieving first gold and the

nature of the expenditure.

The Company will continue to fund 60.3% of the operating costs and capital expenditures and will receive 60.3% of the gold

production.

Production Outlook

Attributable gold production, excluding Côté Gold, for 2024 is expected to be in the range of 430,000 to 490,000 ounces:

• Essakane attributable gold production is expected to be in the range of 330,000 to 370,000 ounces. Production is

expected to remain relatively stable throughout the year with mill throughput expected to operate at nameplate capacity

and head grades are expected to decrease compared to the prior year as the mill feed is supplemented with stockpiled

ore to sustain throughput rates as mining continues through Phase 5 and Phase 6 and into the initial benches of Phase

7.

• Westwood gold production is expected to be in the range of 100,000 to 120,000 ounces in 2024, with an increasing

proportion of underground material milled as the underground mine continues to access higher grade areas. Production

levels are expected to be higher in the first half of 2024 due to mine sequencing in the underground mine and as

supplementary mill feed from the Fayolle open pit is replaced with lower grade material from Grand Duc in the second

half of the year.

Costs Outlook

Consolidated cash costs per ounce sold for Essakane and Westwood are estimated to be between $1,280 and $1,400 per

ounce sold and AISC estimated to be in the range of $1,780 to $1,940 per ounce sold. Unit costs at Westwood are expected

to decrease from 202 3 levels due to increasing production levels, a planned reduction in rehabilitation costs in the

underground mine, and lower development expenses at the short life Fayolle satellite deposit. This is expected to be offset

by an increase in unit costs at Ess akane due to higher planned maintenance activities, the continued pressures on the

landed cost of fuel at the operation, and the application of increased royalty rates announced by the Burkina Faso

government in the fourth quarter 2023, while production le vels are expected to remain the same with an increase in mill

throughput offset by a slightly lower grade mill feed.

While inflationary pressures are easing, pricing for certain main consumables including cyanide and explosives are expected

to remain in line with the levels of 2023, while the price of certain other consumables such as grinding media are expected

to decrease.

Capital Expenditures

Sustaining capital expenditures¹ for 2024 are expected to be approximately $215 million (± 5%) of which the majority is

related to capitalized stripping at Essakane and underground development at Westwood, with an additional $5 million (±

5%) in expansion capital¹ expected at Essakane.

principle of Zero Harm ® in every aspect of its business, with particular emphasis on respecting the natural environment,

building strong community partnerships and putting the health and safety of the Company's employees, contractors and

consultants first.

The Company issued its 16th annual Sustainability Report on October 16, 2023, highlighting progress and achievements in

2022 across a range of material topics and indicators. ESG policies, systems and practices are embedded throughout the

business and the Company reports annually on its ESG performance via its Global Reporting Initiative (“GRI”) and

Sustainability Accounting Standards Board (“SASB”) aligned Sustainability Report. The Company has also released its

inaugural Climate Action Report in accordanc e with the Task Force on Climate -Related Financial Disclosures (“TCFD”)

recommendations on December 14, 2023. The Climate Action Report focuses on the Company’s target of achieving a 30%

absolute reduction in Scopes 1 and 2 greenhouse gas (“GHG”) emissions by 2030.

Health and Safety

Health and safety are core to the Company’s relentless pursuit of its Zero Harm® vision. Through various prevention

programs, the Company continuously promotes a safe work environment and a wellness program at all sites. The DARTFR

(days away, restricted, transferred duty frequency rate) was 0.39 as of the end of 2023 (compared to 0.31 as of the end of

2022). The TRIFR (total recordable injuries frequency rate) was 0.69 as of the end of 2023 (compared to 0.76 as of the end

of 2022). At Côté Gold, total project hours worked reached 14.8 million hours with a LTIFR (lost time injury frequency rate)

of 0.12.

The Essakane team achieved historical Health & Safety performance in 2023, with a level of 0.06 for DARTFR and 0.18 for

TRIFR. The results, which matched (TRI FR) and surpassed (LTIFR) the site’s best -ever results, were supported by

exceptional performance of proactive or ‘leading’ H&S activities such as safety and management inspections.

Environment

At Essakane, progress continued on Falagountou’s Closure Plan, including collaborative work with INERA (Institute of

Environment and Agricultural Research) on the best practice phytoremediation of the closed mine site. Essakane conducted

a quarterly review of the Asset Retirement Obligation with the corporate team and is also working on a water management

study as part of the Essakane Closure Plan.

The 2021 Closure Plan update at Westwood was reviewed by the Quebec Ministry of Natural Resources and Forestry

(“MRNF”) and IAMGOLD submitted an amended Closure Plan on September 8, 2023, following this review process. Water

recycling projects have been in itiated to reduce water withdrawal from the Bousquet River. Westwood is continuing to

implement a biodiversity project to develop snake hibernacula and swallows’ nests.

At Côté Gold, biodiversity monitoring studies were completed for birds and bats. At Mattagami Lake, a fish population study

was also conducted as part of the Project’s Fisheries Offsetting Plan. The first cycle of environmental effects monitoring was

completed per the Metal and Diamond Mining Effluent Regulations.

Social and Economic Development

The Company is continuously exploring opportunities for investing in and partnering with the communities impacted by its

continuing operations.
