Management will host a conference call and webcast today, 9 November 2023, at 8:30 am EST / 1:30 pm GMT . For instructions

on how to participate, please refer to the conference call and webcast section at the end of the news release. A copy of the

Management Report and Financial Statements have been submitted to the National Storage Mechanism. The documents will

shortly be available for inspection on the Company’s website and at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism.

Sebastien de Montessus, President and CEO, commented: “We are pleased with our performance over the first nine months of

the year, which leaves us well positioned to deliver against our strategic objectives.

On the operational front, in light of the efforts made over the first half of the year, our third quarter saw the strongest

performance so far this year, and we expect Q4 performance to be even stronger, which positions us well to meet full-year

production guidance for the eleventh consecutive year and maintain our status as one of the lowest cost gold producers in the

sector. Looking ahead, we expect 2024 to be a strong year for Endeavour, as the brownfield expansion of Sabodala-Massawa

and the Lafigué development project both remain on budget and on track to be commissioned next year.

Alongside this year's investments in our organic pipeline, we are pleased to continue to offer attractive shareholder returns,

delivering $240 million to shareholders over the first nine months of the year. Since we paid our first dividend in Q1-2021, we are

proud to have returned over three quarters of a billion dollars to shareholders in the form of dividends and buybacks, which

represents $354 million more than our minimum commitment for the period. Looking ahead, our goal is to increase our

shareholder returns program, once our two ongoing organic growth projects are complete, to ensure that our efforts to unlock

growth benefit all stakeholders.

Lastly, we are very excited by our exploration program, which continues to provide a strong platform for organic growth. Further

drilling at our recent Tanda-Iguela discovery in Côte d'Ivoire has exceeded expectations, extending the mineralised trend by 50%

and delineating several potential satellite deposits. We are continuing to advance this year's 180,000 meter drill campaign and

look forward to publishing an updated resource estimate later this year.

I would like to thank our team for their continued strong contributions. I look forward to 2024 and beyond as we will benefit from

the efforts undertaken over recent years to improve the quality of our portfolio and strengthen the resilience of our business.”

OPERATING SUMMARY

• Strong safety performance for the Group, with a Lost Time Injury Frequency Rate (“LTIFR”) from continuing operations of

0.08 for the trailing twelve months ending 30 September 2023.

• In line with its guided trend, Q3-2023 was Endeavour’s strongest quarter this year while Q4-2023 is expected to be even

stronger. As such, the Group remains on track to achieve its FY-2023 production guidance from continuing operations of

1,060 – 1,135koz with the group AISC expected to be near the top-end of the guided $895 – 950/oz range.

• Q3-2023 production from continuing operations amounted to 281koz, an increase of 13koz or 5% over Q2-2023, despite the

impact of the wet season, due to increased production from Houndé (as a result of higher grade ore sourced from Kari

Pump), which was partially offset by a decrease in production across Ity and Sabodala-Massawa (due to lower throughputs

and lower average grades), while production at Mana was largely consistent with the prior quarter. Q3-2023 AISC from

continuing operations amounted to an industry-low of $967/oz, which marks a decrease of $33/oz or 3% over Q2-2023 due

largely to lower costs at Houndé (due to higher grades processed and volumes sold) which was partially offset by increased

costs at Ity (due to the impacts of the wet season), Sabodala-Massawa (due to lower volumes of gold sold) and at Mana (due

to higher open pit mining and processing unit costs).

• YTD-2023 production from continuing operations amounted to 792koz, a decrease of 75koz or 9% over YTD-2022 as a result

of decreased production at Sabodala-Massawa (due to lower grade oxide ores processed as per the mine schedule), and at

Mana (due to the slower than expected ramp up of the new Wona Underground mining contractor resulting in lower

processing grades). This was partially offset by increased production at Ity due to improved throughput and recoveries, while

Houndé remained consistent. YTD-2023 AISC from continuing operations amounted to $974/oz, an increase of $136/oz or

16% over YTD-2022, due to increases across Mana, Sabodala-Massawa, and Houndé.

• Total sustaining and non-sustaining capital expenditure for FY-2023 is expected to amount to approximately $327.0 million,

which represents a 2% increase over the previously guided amount of $320.0 million, as detailed below.

• Total sustaining capital expenditure of $71.8 million was incurred in YTD-2023, of which $22.5 million has been incurred in

Q3-2023, primarily related to waste development and mining equipment upgrades at Houndé, Ity and Sabodala-Massawa as

well as new infrastructure at Mana. The FY-2023 sustaining capital expenditure for continuing operations is expected to

3

amount to $100.0 million compared to the previously provided outlook of $110.0 million due to a $10.0 million reduction at

Sabodala-Massawa in line with the production profile and due to the acceleration of the Niakafiri East and Sofia North

Extension pits into the mine plan which allows stripping activity initially planned in the Massawa zone to be deferred until

next year.

• Total non-sustaining capital expenditure of $192.8 million was incurred in YTD-2023, of which, $49.5 million has been

incurred in Q3-2023, primarily related to waste stripping activities at Houndé; TSF construction, embankment raises and the

Recyn and Mineral Sizer optimisation initiatives at Ity; the solar power plant construction at Sabodala-Massawa; and ongoing

underground development at Mana. The FY-2023 non-sustaining capital expenditure for continuing operations is expected to

amount to $227.0 million compared to the previously provided outlook of $210.0 million due to a $10.0 million increase at

Mana (related to increased underground development costs associated with the slower than expected ramp-up of the Wona

Underground mining contractor) and a $7.0 million increase at Ity (as the Tailings Storage Facility (“TSF”) embankment raise

and the construction of a new TSF have been accelerated) due to its strong performance this year.

• The growth capital expenditure outlook for FY-2023 remains unchanged at $400.0 million, with $292.5 million incurred in

YTD-2023, of which $116.2 million has been incurred in Q3-2023. In Q3-2023, a total of $50.4 million was incurred for the

Sabodala-Massawa BIOX® expansion project, $63.8 million was incurred for the Lafigué development project, and

$2.0 million was incurred for the Kalana project.

SHAREHOLDER RETURNS PROGRAMME

• The Company is pleased to continue to deliver attractive shareholder returns, despite the significant growth capital

investments being undertaken this year. Endeavour paid its H1-2023 dividend of $100.0 million, or $0.40 per share, on 26

September 2023, to shareholders of record on 1 September 2023. On an annualised basis, the H1-2023 dividend represents

$25.0 million, or 14%, more than the minimum dividend commitment for the year of $175.0 million.

• In addition, shareholder returns continued to be supplemented with share buybacks as $40.0 million or 1.8 million shares

were repurchased in YTD-2023, of which $20.0 million or 1.0 million shares were repurchased in Q3-2023. Since the

commencement of the buyback programme on 9 April 2021, a total of $277.0 million, or 12.4 million shares have been

repurchased as at 30 September 2023.

• As shown in the table below, Endeavour has returned $777.0 million to shareholders in the form of dividends and buybacks ,

equivalent to $202/oz produced from all operations, since its shareholder returns programme began in late 2020 (first

dividend payment in Q1-2021), which represents $354.0 million more than its minimum commitment for the period.

NOTES:

1) Operating cash flows decreased by $44.4 million from $159.3 million (or $0.64 per share) in Q2-2023 to $114.9 million (or

$0.47 per share) in Q3-2023 due to a lower realised gold price and higher taxes paid related to the timing of withholding

5

tax payments and the prior period incorporating operating cashflow generated by the divested Boungou and Wahgnion

mines.

Operating cash flows decreased by $226.5 million from $706.3 million (or $2.85 per share) in YTD-2022 to $479.8 million

(or $1.94 per share) in YTD-2023 due to lower production, increased operating and exploration costs, higher tax

payments and the prior period containing significant cashflow generated by discontinued operations, which was partially

offset by a decrease in working capital outflows.

Notable variances are summarised below:

• Working capital was an outflo w of $5.2 million in Q3-2023, a decrease of $9.0 million over the Q2-2023 outflow of

$14.2 million. The outflow in Q3-2023 was largely driven by a prepaid expenses and other outflow of $8.6 million

related to advanced insurance and security payments , and a trade and other payables outflow of $1.2 million related

to the timing of payments. The outflow was partially offset by a n inflow of inventories of $6.8 million mainly related

to decreased warehouse inventory at Sabodala-Massawa, Ity, and Houndé and an increase in stockpiles at Sabodala-

Massawa, and an outflow in trade and other receivables of $2.2 million related to the timing of VAT receipts.

Working capital was an outflow of $47.4 million in YTD-2023, a decrease of $68.5 million over the YTD-2022 outflow

of $115.9 million, largely driven by a decrease in outflows related to trade and other payables due t o the timing of

supplier and royalty payments in YTD-2022.

• Gold sales from continuing operations increased from 269koz in Q2-2023 to 278koz in Q3-2023 following increased

production at Houndé, which was partially offset by decreased production at Ity and Sabodala-Massawa. The realised

gold price from continuing operations for Q3-2023 was $1,898 per ounce compared to $1,943 per ounce for Q2-2023.

Inclusive of the Group’s Revenue Protection Programme, the realised gold price for Q3-2023 was $1,903 per ounce

compared to $1,947 per ounce for Q2-2023.

Gold sales from continuing operations decreased from 860koz in YTD-2022 to 799koz in YTD-2023, following lower

Group production in YTD-2023. The realised gold price from continuing operations for YTD-2023 was $1,915 per

ounce compared to $1,808 per ounce for YTD-2022. Inclusive of the Group’s Revenue Protection Programme, the

realised gold price for YTD-2023 was $1,910 per ounce compared to $1,824 per ounce for YTD-2022.

• Total cash cost per ounce decreased from $868 per ounce in Q2-2023 to $848 per ounce in Q3-2023, primarily due to

increased gold sold at a Group level and lower processing unit costs at Houndé, which was partially offset by

increased cash costs at Ity due to lower gold volumes sold and wet season impacts, at Mana due to an increase in

waste mining, and at Sabodala-Massawa due to higher processing costs associated with higher fuel and consumable

prices.

Total cash cost per ounce increased from $716 per ounce in YTD-2022 to $837 per ounce in YTD-2023 due to lower

production and gold sold at Sabodala-Massawa and Mana in addition to increases in fuel and consumable costs across

the Group.

• As shown in the table below, i ncome taxes paid increased by $38.4 million from $103.6 million in Q2-2023 to $142.0

million in Q3-2023 due largely to a $44.1 million withholding tax payment linked to a portion of the cash expected to

be upstreamed from operating entities this year, in addition to higher corporate taxes paid at Sabodala-Massawa

linked to the timing of provisional payments, which was partially offset by lower corporate taxes paid at Ity, Mana,

and Houndé.

Income taxes paid increased by $124.2 million from $145.8 million in YTD-2022 to $270.0 million in YTD-2023 due

largely to the increase in taxes paid at Sabodala-Massawa as provisional tax payments made in the YTD-2022 period

were based off of the 2021 tax base which benefited from a tax holiday at the Massawa permit which expired at the

end of 2021 in addition to higher provisional payments made at Ity and Sabodala-Massawa in the YTD-2023 period

based on the higher tax base of those assets in 2022, following the start of production on the Floleu permit which

carries a higher tax rate and the above mentioned expiry of the tax holiday on the Massawa permit respectively.

2) Cashflows used in investing activities decreased by $19.3 million from $214.4 million in Q2-2023 to $195.1 million in

Q3-2023 due to a decrease in non-sustaining capital spend related to reduced capitalised development at Mana and

Sabodala-Massawa as access to ore increased, while the prior period included investing cashflows related to divested

6

assets. In addition an investment of $10.0 million in marketable securities in Allied Merger Corporation (“Allied”) was

completed during Q3-2023, resulting in Endeavour now owning 14.1 million shares , equivalent to 3.4% of Allied’s total

shares outstanding. The decrease in cashflows used in investing activities was partially offset by accelerated growth

capital spend in Q3-2023 at the Sabodala-Massawa expansion and the Lafigué development project.

Cashflows used in investing activities increased by $260.6 million from $349.2 million in YTD-2022 to $609.8 million in

YTD-2023 largely due to the increases in growth capital incurred at the Sabodala-Massawa expansion, which was

launched in Q2-2022, and the Lafigué development project, which was launched in Q4-2022.

• Sustaining capital from continuing operations of $22.5 million in Q3-2023 was largely in-line with the prior quarter as

increased sustaining capital expenditure at Sabodala-Massawa (related to waste capitalisation at Bambaraya and

mining equipment upgrades) was largely offset by decreased expenditure at Houndé and Ity due to less waste

capitalisation.

Sustaining capital from continuing operations of $71.8 million in YTD-2023 was largely in-line with the prior period as

increased sustaining capital expenditure at Houndé (related to waste development activities at the Vindaloo and Kari

Pump pits), and at Mana (related to infrastructure and underground development) was offset by decreased sustaining

capital expenditure at Sabodala-Massawa (as waste development in existing pits moved to focus on new pits), and at

Ity (due to less waste development).

• Non-sustaining capital from continuing operations decreased from $60.6 million in Q2-2023 to $49.5 million in

Q3-2023, largely due to a decrease in non-sustaining capital at Mana (as spend on underground development was

reduced as more stoping commenced), and at Sabodala-Massawa (as spend on new deposits decreased as they

advanced into production), and at Houndé and Ity (due to a decrease in pre-stripping activities).

Non-sustaining capital from continuing operations increased from $131.8 million in YTD-2022 to $192.8 million in

YTD-2023 due to increased non-sustaining capital expenditure at Ity (related to ongoing construction of the Recyn and

Mineral Sizer optimisation initiatives, the embankment raise at TSF 1 and the construction of TSF 2), at Sabodala-

Massawa and Houndé (due to increased pre-stripping activities as new pits and new phases of existing pits were

opened), and at Mana (due to increased underground development and the ongoing TSF embankment raise).

• Growth capital increased from $104.1 million in Q2-2023 to $116.2 million in Q3-2023, as construction activities at the

Sabodala-Massawa expansion and the Lafigué development project accelerated. Growth capital expenditure during

the quarter also included $2.0 million for work related to the Kalana project.

Growth capital increased from $71.9 million in YTD-2022 to $292.5 million million in YTD-2023 largely due to the

acceleration of construction activities at the Sabodala-Massawa expansion, which was launched in Q2-2022, and the

launch of construction at the Lafigué development project, which was launched in Q4-2022.

3) Cash flows used in financing activities increased by $207.3 million from an inflow of $82.7 million in Q2-2023 to an

outflow of $124.6 million in Q3-2023 largely due to the timing of dividend payments to shareholders and minorities.

Financing cash outflows in Q3-2023 included payment of the H1-2023 dividend to shareholders of $99.0 million, payment

of dividends to minorities of $55.3 million, payments for the acquisition of the Company’s own shares through its share

buyback programme of $16.7 million, payments of financing and other fees of $4.7 million related to the coupon

payments for the senior notes and the RCF and repayment of finance and lease obligations of $4.0 million. Outflows were

partially offset by a $55.1 million drawdown on the Company’s $645.0 million RCF to manage short term offshore cash

flow requirements.

Cash flows used in financing activities decreased by $129.0 million from an outflow of $326.6 million in YTD-2022 to

$197.6 million in YTD-2023 largely due to drawing on the company’s RCF during the current period.

4) At quarter end, Endeavour’s liquidity remained strong at $867.1 million, consisting of $625.1 million of cash and cash

equivalents, $110.0 million available through the Company’s RCF, and $132.0 million available through the Lafigué Term

Loan. In addition, Endeavour expects to receive proceeds of $97.0 million for the divestment of the non-core Boungou

and Wahgnion mines before year-end, as described in section “Non-core Asset Divestment” below.

5) Endeavour’s net debt position has increased by $274.5 million, from $170.5 million at the end of Q2-2023 to $445.0

million at the end of Q3-2023 due to the Company’s ongoing focus on completing its growth projects, timing of tax

payments and timing of dividend payments. The Company’s net debt / Adjusted EBITDA (LTM) leverage ratio remains

healthy at 0.40x at the end of Q3-2023 despite the strong focus on investing in its organic growth.

NOTES:

6) Revenue increased by $5.9 million from $524.1 million in Q2-2023 to $530.0 million in Q3-2023 due to an increase in gold

sales from continuing operations from 269koz in Q2-2023 to 278koz in Q3-2023, following higher production at Houndé,

partially offset by a $45 per ounce decrease in the realised gold price from $1,943 per ounce in Q2-2023 to $1,898 per

ounce in Q3-2023, exclusive of the Company’s Revenue Protection Programme.

Revenue decreased by $26.3 million from $1,561.6 million in YTD-2022 to $1,535.3 million in YTD-2023 due to a decrease

in gold sales from continuing operations from 860koz in YTD-2022 to 799koz in YTD-2023, partly offset by a higher

realised gold price for YTD-2023 of $1,915 per ounce compared to $1,808 per ounce for YTD-2022, exclusive of the

Company’s Revenue Protection Programme.

7) Operating expenses increased by $3.5 million from $201.8 million in Q2-2023 to $205.3 million in Q3-2023 largely due to

increased operating costs at Houndé and Mana as a result of higher strip ratios in current ore mining areas and increases

in fuel and consumable costs. Depreciation and depletion increased by $14.9 million from $99.5 million in Q2-2023 to

$114.4 million in Q3-2023 mainly due to increased depletion at Houndé as a result of higher quarterly production.

Operating expenses increased by $44.8 million from $533.7 million in YTD-2022 to $578.5 million in YTD-2023 largely due

to increased volumes mined and processed at Ity and Houndé in addition to increases in fuel and consumable costs.
