Management will host a conference call and webcast today, Thursday 30 April 2026, at 8:30 am EDT / 1:30 pm BST. For

instructions on how to participate, please refer to the conference call and webcast section at the end of the news release. T he

Management Discussion & Analysis and Financial Statements have been submitted to the National Storage Mechanism and filed

on SEDAR+. The documents will shortly be available for inspection on the Company’s website and at:

https://data.fca.org.uk/#/nsm/nationalstoragemechanism. In addition, today the Company has published its 2025 Tax and

Economic Contribution Report, which will be available on the Company’s website.

Ian Cockerill, Chief Executive Officer, commented: "We delivered a strong start to 2026, building on last year’s momentum with

another solid quarter of operational performance and record financial results.

We remain on track to achieve full -year guidance, with performance weighted towards the second half of the year, reflecting the

mining sequence at our Houndé, Mana and Ity mines.

Strong operational delivery, combined with continued strength in the gold price, translated into record adjusted EBITDA of $8 80

million, up 29% over Q4 -2025, and record free cash flow of $613 million, equivalent to $2,176 per ounce, up 29% over Q4 -2025.

This cash generation supported further improvement in our balance sheet, which now stands at $405 million of net cash.

Our financial strength gives us flexibility to simultaneously start construction at Assafou and deliver on our sector leading

shareholder returns programme. We expect to significantly exceed our minimum commitment for the year, and at prevailing gold

prices, we could more than double it, supported by over $54 million of supplemental share buybacks completed already this yea r.

At Assafou, the recently announced DFS confirmed the scale and quality of this potential cornerstone project that underpins o ur

organic growth to 1.5 million ounces by 2030. Early works are now well underway, procurement of long -lead items has been

launched, detailed engineering and design advancing, relocation action planning in progress and key tender negotiations near

complete as we target a final investment decision before the end of the year. The DFS significantly optimised and de -risked the

project, which can now support future expansions as we continue to grow the resource base.

Our exploration programme is advancing on multiple fronts. The Vindaloo Deeps discovery at our Houndé mine is expected to

materially enhance the life -of-mine plan, with a maiden resource expected in H1 this year. Elsewhere, resource development at

our core assets is expected to support an improved reserves and resources outlook at year -end, while our greenfield programme

continues to generate high-priority targets across our selected tier 1 gold provinces.

Importantly, as we grow the business and deliver returns to our shareholders, our stakeholders also benefit. Last year we

contributed $2.8 billion to our host nations, a 27% increase over the previous year - re-iterating the strong alignment between

our performance, and our contributions to host countries, particularly in this higher gold price environment. Sustainable val ue

creation requires us to continually strengthen our governance, stakeholder engagement and management systems across the

business, ensuring ESG is effectively embedded in how we operate. This approach has been recognised in the recent upgrade of

our ISS Corporate Rating to B-, positioning Endeavour within the top 10% of our industry.

With a high -quality portfolio and a strong organic growth pipeline, we are well positioned to sustainably deliver sector -leading

growth and shareholder returns, creating long-term value for all stakeholders.”

SHAREHOLDER RETURNS PROGRAMME

• Endeavour has paid more than $1.6bn in shareholder returns since Q1 -2021, which is $730.3 million or 83% above its

minimum commitment over the period, reflecting its commitment to delivering sector leading shareholder returns.

• For FY-2025 Endeavour returned $435.0 million to shareholders including $350.0 million of dividends and $85.3 million of

share buybacks, 93% above its minimum commitment.

• Over the 2026 - 2028 period, Endeavour expects to return a minimum dividend of approximately $1.0 billion to shareholders,

comprised of $300.0 million for FY -2026, $325.0 million for FY -2027, and $350.0 million for FY -2028, provided the realised

gold price over the dividend period exceeds $3,000/oz. At prevailing gold prices, Endeavour expects to return at least $2.0

billion to shareholders through approximately $1.0 billion of minimum dividends and $1.0 billion of supplemental dividends

and share buybacks.

• During H1 -2026, shareholder returns have continued to be supplemented with $53.9 million, or 0.9 million shares, of

buybacks up to 28 April 2026, with $29.7 million, or 0.5 million shares, of buybacks completed during Q1 -2026. H1 -2026

dividends will be declared within Endeavour’s Q2 and H1-2026 results.

• The minimum dividend is expected to be paid semi -annually, provided that the prevailing realised gold price for the dividend

period is at or above $3,000/oz, and the Company's leverage remains below its long term target of 0.50x net debt / Adjusted

EBITDA (LTM). Supplemental dividends and share buybacks are expected to be paid, if the gold price exceeds $3,000/oz and if

the Company's leverage remains below its long term target of 0.50x net debt / Adjusted EBITDA (LTM).

OPERATING SUMMARY

• Endeavour puts the highest priority on safety and the Company’s ultimate aim is to achieve “zero harm” performance. As

previously disclosed, on 9 March 2026, we were saddened to report that a contractor colleague passed away on 6 March

2026, as a result of injuries sustained in an incident that occurred during decommissioning activities at our Mana mine in

Burkina Faso. The health, safety and welfare of our colleagues remain our top priority and following the incident a

comprehensive investigation was completed with several improvements currently being implemented, including enhanced

contractor onboarding processes and reinforcing safety training for both contractors and Endeavour supervisors.

• For the trailing twelve months, ended 31 March 2026, a low Total Recordable Injury Frequency Rate (“TRIFR”) of 0.72 was

achieved.

• The Group remains on track to achieve its production guidance of 1,090 - 1,265koz, within its all -in sustaining cost (“AISC”)

guidance range of $1,600 - 1,800/oz, when adjusted for the impact of higher gold prices on royalty costs compared to the

guidance gold price of $3,000/oz. Q1 -2026 production of 282koz is equivalent to approximately 26% of the low -end of the

guided range, with increased production expected in H2-2026 at Houndé, Mana and Ity, positioning the Group well to achieve

production guidance. Similarly Q1-2026 AISC, on a royalty adjusted basis, of $1,642/oz (Q1-2026 AISC of $1,834/oz before the

impact of higher gold prices on royalty costs of $192/oz, due to the realised gold price of $4,842/oz exclusive of the Sabodala-

Massawa stream, above the guidance gold price of $3,000/oz), is towards the lower-end of the guidance range.

4

• Q1-2026 production of 282koz was 17koz lower than Q4-2025, due to lower production at Sabodala -Massawa, Mana, and Ity

as lower average grades were processed in line with the mining sequence, partially offset by increased production at Houndé

and Lafigué as higher average grades were processed.

• Q1-2026 AISC amounted to $1,834/oz, an increase of $187/oz over Q4-2025, due to lower Group production, higher gold

price driven royalty costs (+$108/oz impact due to the realised gold price of $4,842/oz, exclusive of the Sabodala -Massawa

stream compared, to Q4 -2025 realised gold price of $4,227/oz), higher sustaining capital related to stripping activity at

Lafigué, Houndé and Sabodala -Massawa, and lower grid power utilisation at Mana. This was partially offset by lower costs at

Ity due to lower sustaining capital and higher by-product revenue from silver sales.

NOTES:

1) Operating cash flows increased by $128.4 million from $609.0 million (or $2.52 per share) in Q4 -2025 to $737.4 million

(or $3.05 per share) in Q1 -2026 due to higher realised gold prices, lower operating costs and the realised loss on gold

collars in the prior quarter, partially offset by higher income tax payments, higher royalty costs due to the higher realised

gold price, a decrease in production and gold sales and an increase in the working capital outflow.

Operating cash flows increased by $243.2 million from $494.2 million (or $2.03 per share) in Q1 -2025 to $737.4 million

(or $3.05 per share) in Q1 -2026 due to the higher realised gold prices, a lower working capital outflow and the realised

loss on gold collars in the prior period, partially offset by higher operating costs, higher royalty costs and higher income

tax payments.

Notable variances are summarised below:

• Working capital was an outflow of $91.2 million in Q1 -2026, an increase of $75.2 million over the Q4 -2025 outflow of

$16.0 million. The outflow in Q1 -2026 consisted of (i) a trade and payables outflow of $44.3 million related to

decreases in supplier payables and payroll -related liabilities from the prior quarter, (ii) an outflow of $24.1 million

primarily related to VAT receivables at Houndé and Mana, (iii) an outflow of $20.5 million related to a build up of

consumable inventory at Mana and Houndé related to the build up of fuel supplies and stockpile inventory at Ity and

Sabodala-Massawa, partially offset by a drawdown of stockpiles at Lafigué and (iv) an outflow of $2.3 million related

to the timing of supplier prepayments.

Working capital was an outflow of $91.2 million in Q1-2026, an improvement of $6.8 million over the Q1-2025 outflow

of $98.0 million, largely driven by a decrease in outflows related to stockpile inventory and VAT receivables, partially

offset by an increase in outflows related to trade and other payables due to the timing of supplier payments and an

increase in outflows related to supplier prepayments.

• Gold sales from continuing operations decreased from 302koz in Q4 -2025 to 278koz in Q1 -2026 due to lower

production at Ity, Mana and Sabodala -Massawa, partially offset by higher production at Houndé and Lafigué. The

realised gold price from continuing operations for Q1 -2026 increased by $609/oz to $4,810/oz from $4,201/oz in Q4 -

2025.

6

Gold sales from continuing operations decreased from 353koz in Q1 -2025 to 278koz in Q1 -2026 due to lower

production at the Houndé, Ity, Mana and Sabodala -Massawa mines partially offset by increased production from the

Lafigué mine. The realised gold price from continuing operations for Q1 -2026 increased by $1,871/oz to $4,810/oz

from $2,939/oz in Q1-2025.

• Total cash cost per ounce increased from $1,448/oz in Q4-2025 to $1,516/oz in Q1-2026 due to lower volumes of gold

sold and higher royalty costs (+$108/oz impact at realised gold price of $4,842/oz exclusive of the Sabodala -Massawa

stream vs Q4 -2025 realised gold price of $4,201/oz) related to a higher realised gold price, partially offset by a build

up of stockpile inventory at Ity and Sabodala -Massawa which results in a capitalisation of mining costs as a credit to

operating costs during the quarter.

Total cash cost per ounce increased from $929/oz in Q1 -2025 to $1,516/oz in Q1 -2026 due to significantly higher

royalty costs (+$236/oz impact at realised gold price of $4,842/oz exclusive of the Sabodala -Massawa stream vs Q1 -

2025 realised gold price of $2,783/oz) related to the higher realised gold price, lower volumes of gold sold, higher

process unit costs at Houndé and Ity due to lower grid power availability and higher mining unit costs at Mana due to

increased diesel consumption in the Wona underground.

• Taxes paid increased by $22.7 million from $22.8 million in Q4 -2025 to $45.5 million in Q1 -2026 due to higher

corporate income tax payments reflecting higher taxable earnings and the advanced payment of withholding taxes at

Sabodala-Massawa, partially offset by lower corporate income tax payments at Houndé and Mana. Given the higher

realised gold price in Q1 -2026 of $4,810/oz, compared to the $3,000/oz guidance gold price, the withholding tax

guidance range in Table 7 below has been increased from $90.0 - 100.0 million to $150.0 - 170.0 million, reflecting the

projected increase in cash upstreaming.

Taxes paid increased by $6.5 million from $39.0 million in Q1 -2025 to $45.5 million in Q1 -2026 as income tax

payments increased at the Houndé, Mana and Sabodala -Massawa mines relating to higher FY -2025 taxable income,

while withholding tax payments increased at Sabodala-Massawa related to cash upstreaming.

1The income tax outlook is expected to be largely stable with gold price changes, but will fluctuate with foreign exchange movements, unforeseen

tax settlements and annual true ups. 2Withholding tax guidance has been updated at Q1-2026 to reflect increased cash upstreaming due to higher

realised gold prices.

2) Cash flows used in investing activities decreased by $7.9 million from $132.7 million in Q4 -2025 to $124.8 million in Q1 -

2026 due to a decrease in non -sustaining capital spend of $23.9 million, an $8.1 million movement in restricted cash

related to the payment of the 2% incremental royalty rate in Côte d’Ivoire and a decrease in growth capital spend of $1.8

million, partially offset by an increase in sustaining capital spend of $27.5 million and an outflow of $2.7 million related to

the conversion of the convertible loan associated with the Group’s strategic investment in East Star Resources plc.

Cash flows used in investing activities increased by $40.0 million from $84.8 million in Q1 -2025 to $124.8 million in Q1 -

2026 due to an increase in sustaining capital spend of $18.9 million, an increase in non -sustaining capital spend of $7.6

million and a decrease in restricted cash inflow of $13.5 million, partially offset by a decrease in growth capital spend of

$8.4 million.

• Sustaining capital increased from $47.1 million in Q4 -2025 to $74.6 million in Q1 -2026, largely due to increased waste

stripping at the Lafigué and Sabodala -Massawa mines and increased heavy mining equipment additions and rebuilds

7

at Houndé, partially offset by lower underground development at Mana and lower processing plant capital

expenditure at Ity.

Sustaining capital increased from $55.7 million in Q1 -2025 to $74.6 million in Q1 -2026 largely due to increased waste

stripping at the Lafigué, Houndé and Ity mines, partially offset by a lower underground mine development at Mana

and lower waste stripping at Sabodala-Massawa.

• Non-sustaining capital decreased from $69.1 million in Q4 -2025 to $45.2 million in Q1 -2026 largely due to a decrease

in land compensation and waste stripping at the Houndé mine, lower expenditure on processing plant upgrades at

Sabodala-Massawa and lower capital expenditure on the TSF stage 6 embankment raise at Mana.

Non-sustaining capital increased from $37.6 million in Q1 -2025 to $45.2 million in Q1 -2026 largely due to TSF

construction, resettlement costs and waste stripping at Houndé, increased expenditure associated with the TSF 2

stage 2 embankment raise at Ity and increased expenditure on processing plant upgrades at Sabodala -Massawa. This

was partially offset by lower waste stripping at Lafigué.

• Growth capital decreased from $9.7 million in Q4 -2025 to $6.0 million in Q1 -2026. Growth capital expenditure in Q1 -

2026 was related to the Assafou project’s definitive feasibility study.

Growth capital increased from $5.7 million in Q1 -2025 to $6.0 million in Q1 -2026. Growth capital expenditure in Q1 -

2026 was related to the Assafou project definitive feasibility study.

3) Free cash flow increased by $136.3 million from $476.3 million in Q4 -2025 to $612.6 million in Q1 -2026 largely due to

increased operating cash flows as a result of higher realised gold prices, lower operating costs and lower realised losses

following the completion of the revenue protection programme, and lower investing cash flows due to lower quarterly

non-sustaining capital and growth capital.

Free cash flow increased by $203.2 million from $409.4 million in Q1 -2025 to $612.6 million in Q1 -2026 largely due to

higher realised gold prices and lower realised losses following the completion of the revenue protection programme,

partially offset by increased investing cash flows due to higher sustaining and non-sustaining capital.

4) Cash flows from financing activities improved by $288.5 million from an outflow of $252.7 million in Q4 -2025 to an inflow

of $35.8 million in Q1 -2026 largely due to the payment of the H1 -2025 shareholder dividend in the prior quarter, a net

drawdown of $74.7 million on the Group’s revolving credit facility, a reduction of $18.8 million in financing fees and a $2.6

million reduction in interest paid. The decrease was offset by a $23.7 million increase in the repurchase of shares through

the Group’s share buyback programme and a $0.4 million increase in the repayment of leases.

Cash flows from financing activities improved by $102.6 million from an outflow of $66.8 million in Q1 -2025 to an inflow

of $35.8 million in Q1 -2026 largely due to a net outflow of $74.7 million on the Group’s revolving credit facility, a $13.0

million decrease in purchases of shares through the Group’s share buyback programme, a $7.9 million decrease in

financing fees and a $1.7 million decrease in payments related to the settlement of tracker shares, partially offset by a

$1.2 million increase in repayments of leases.

5) Endeavour’s net cash position improved by $562.9 million, from a net debt position of $157.5 million at the end of Q4 -

2025 to a net cash position of $405.4 million at the end of Q1 -2026, while the Net Cash (Debt) / Adjusted EBITDA (LTM)

leverage ratio improved from (0.07)x at the end of Q4 -2025 to 0.16x at the end of Q1 -2026. Endeavour’s liquidity

improved significantly to $1,704.5 million, consisting of $1,089.5 million of cash and cash equivalents and $615.0 million

available through the Company’s revolving credit facility.

NOTES:

6) Revenue increased by $75.2 million from $1,273.8 million in Q4 -2025 to $1,349.0 million in Q1-2026 due to an increase in

the realised gold price from $4,201/oz, exclusive of the impact of the Group’s Revenue Protection Programme, in Q4-2025

to $4,810/oz in Q1-2026, partially offset by lower volumes of gold sold.

Revenue increased by $307.2 million from $1,041.8 million in Q1 -2025 to $1,349.0 million in Q1 -2026 due to an increase

in the realised gold price from $2,939/oz, exclusive of the impact of the Group’s Revenue Protection Programme, in Q1 -

2025 to $4,810/oz in Q1-2026, partially offset by lower volumes of gold sold.

7) Operating expenses decreased by $32.9 million from $341.4 million in Q4 -2025 to $308.5 million in Q1 -2026, largely due

to lower production and a build up of stockpile inventory at Ity and Sabodala -Massawa, which results in the capitalisation

of mining costs and a decrease in operating costs during the quarter. This was partially offset by a drawdown of stockpile

inventory at Lafigué. Depreciation and depletion decreased by $25.5 million from $174.2 million in Q4 -2025 to $148.7

million in Q1-2026 due to lower quarterly production.

Operating expenses increased by $49.5 million from $259.0 million in Q1 -2025 to $308.5 million in Q1-2026 due to higher

processing costs at Houndé and Ity related to reduced grid power availability during the quarter, and higher mining costs

at Ity and Lafigué related to higher mining volumes. Depreciation and depletion decreased by $25.9 million from $174.6

million in Q1-2025 to $148.7 million in Q1-2026 due to lower quarterly production.

8) Royalties increased by $22.3 million from $103.0 million in Q4 -2025 to $125.2 million in Q1 -2026 due to the higher

realised gold price during the quarter and the increase in Côte d’Ivoire royalty rates from 6% to 8% that was retroactively

applied from 2025, partially offset by lower volumes of gold sold.
