TABLE OF CONTENTS

CEO OPERATIONAL Review

(H1 2023 vs H1 2022)

I am pleased to report a strong first half of 2023 due to the continued operational delivery at Sukari, coupled with a stronger gold price. We have also advanced numerous projects and work streams that will deliver the full potential of Centamin's portfolio. We remain on track to deliver against our 2023 guidance and all key capital projects are progressing on schedule.

HEALTH & SAFETY

We remain focussed on the protection of our workforce and the local communities that we work in. Our safety performance continues to be strong; while noting that our ultimate ambition is to create a zero-harm workplace.

We had only one lost time injury in H1 2023 at Sukari. Notwithstanding, there has been an increase in low consequence, minor injuries. Proactive measures have been taken to understand these injuries, identify trends, and implement mitigations. These measures include 'safety stops' focused on awareness sessions and the implementation of programmes that ensure greater management oversight and enhance hazard identification education.

The Group LTIFR was 0.15 per one million hours worked and we are on track to meet our annual target. The Group TRIFR was 2.94 per one million hours worked, a 1% increase YoY.

SUSTAINABILITY

Centamin published its sixth annual Sustainability Report and 2022 Modern Slavery Statement. The Sustainability Report was aligned with globally recognised reporting frameworks including GRI Sustainability Reporting Standards ("GRI"), the Sustainability Accounting Standards Board ("SASB") for the metals and mining industry, and the Task Force on Climate-related Financial Disclosures ("TCFD"). Furthermore, we have strengthened our third-party verification and assurance processes, around our greenhouse gas accounting, people and workforce development frameworks, gender inclusion and diversity, and closure cost liability.

Tailings management

Our comprehensive and systematic approach to tailings management continues, with good progress on bringing the governance processes and management systems in line with the Global Industry Standard on Tailings Management ("GISTM"). The raising of our second tailings storage facility ("TSF2") continues to progress ahead of schedule.

Energy and climate change

In March 2023, we issued our decarbonisation roadmap to 2030 with an interim 30% carbon abatement target. This science-based target is underpinned by integrating and expanding solar power generation at Sukari, combined with switching to lower carbon Egyptian grid power. This will fully replace the current use of diesel fuel for power generation at Sukari.

The Sukari 30MW_AC solar plant has now been operating for nine months and has exceeded project power generation expectations, showcasing exceptional performance as we operate in the peak sunlight hours during the summer months. The preliminary technical work to expand the Sukari solar capacity to 50MW_AC is complete and advanced studies are underway including project design and timeline. The tender process for the Egyptian grid connection was launched in Q1. All qualifying proposals have been received and are currently under review by our management team supported by external technical advisors. The estimated target for grid connection is 2024. These two carbon abatement initiatives will reduce our GHG carbon emissions by 30% from our 2021 base year by 2023 and deliver significant cost-savings.

Professional development

In H2 2023, alongside the second year of our Employee Development Pathway we will also be rolling out the Leadership Development Pathway at Sukari, targeted at all management and supervisory roles. We are committed to educate, develop and empower our workforce with the requisite tools and skills to continue to deliver operational excellence.

SUKARI GOLD MINE (Egypt)

The Sukari team delivered another solid operational performance in H1 2023 and we remain on track to meet the midpoint of 2023 production guidance. Total open pit material mined was 65Mt, a 1% increase YoY. The accelerated waste-stripping programme continues to yield positive results, increasing operational flexibility with multiple working areas available in the north, east and west of the pit. The Centamin fleet mined 36Mt of waste in H1 2023. The waste mining contractor mined an additional 22Mt, resulting in the total contracted 120Mt programme being approximately 70% complete, with scheduled completion mid-2024.

In terms of total open pit ore tonnes, Sukari achieved 7Mt with an average grade of 0.88g/t Au. This marks a 20% increase in tonnes and an 11% decrease in grade YoY, reflecting the scheduled inclusion of low-grade oxide and transitional ore tonnes from Stage 7, which will be placed on the dump leach. Open pit average milled grade was 0.99 g/t Au for H1 2023, a 2% decrease YoY.

The underground mine continues to benefit from the transition to owner mining, as demonstrated by a 19% increase in ore tonnage mined YoY. Grades remained consistent YoY, averaging 4.2g/t Au. We anticipate a slight improvement in average grades during H2 2023. The key focus within the underground is augmenting the fleet with a staged replacement of end-of-life equipment, whilst simultaneously introducing the use of paste-fill into the operating cycle.

The underground paste-fill plant commenced commissioning during Q2 pouring the first paste into trial stopes, with the excellent results for both Portland and slag cement strength. As part of the commissioning phase, we are conducting various performance monitoring and optimisation programmes such as viscosity modelling test work as we work to refine the process. It's worth noting that the trial stopes are located within historically mined areas, ensuring no disruption to current mining operations. To ensure a seamless transition, we will continue to utilise the existing underground backfilling system of cemented rock fill ("CRF") and waste rock fill in parallel with the commissioning of the paste plant. This approach mitigates implementation risk while maintaining ongoing mining operations.

As planned, the plant processed 6Mt of ore at an average feed grade of 1.23 g/t Au, a 4% increase YoY in tonnes and 1% in grade. There were several key projects during the period, including mill relining and work on the mill motors, all of which were completed successfully with no unplanned disruption to throughput.

The metallurgical gold recovery rate was 88.5%, in line with budget and flat YoY. Work on the gravity circuit continued to progress with design reviews nearing completion. The design review is underway with a detailed design tender and construction decision by the end of 2023.

Significant progress has been made on the North Dump leach project, with the installation of the high-density polyethylene ("HDPE") liner completed, and the base layer of mill scats placed on top of the liner. Ore placement has commenced on the fully constructed cells. We aim to initiate leaching activities in H2 2023, depending on the percolation rates, this could potentially result in the first pregnant gold solution being generated at the end of 2023.

The optimised life of mine plan is on track for completion in Q4, including the fully-engineered underground expansion. Our team has recently concluded a comprehensive work programme with external support, specifically addressing the updated geotechnical parameters that will assist in determining the criteria for the revised open pit and underground mine design. Moving ahead, our focus will be on analysing the initial outputs derived from the revised input parameters, as well as refining the open pit stage design, expanded underground and equipment maintenance strategy.

Doropo GOLD Project (Côte d'Ivoire)

On 27 June 2023, we published the results from the Doropo pre-feasibility study ("PFS"), which demonstrated the economic robustness of the project with a post-tax NPV₈% of US$497 million and an IRR of 41% at US$1,900/oz gold prices. Importantly, using a more conservative long-term gold price of US$1,600/oz, the project meets Centamin's hurdle rates and the definitive feasibility study ("DFS") and environmental and social impact assessment ("ESIA") are well underway and expected to be completed in H1 2024, ahead of the mining licence submission.

Doropo ESIA terms of reference were approved by the Ivorian government with work commencing immediately afterwards. Baseline studies and the impact assessment are well advanced supporting the optimisation of the project design and accompanying stakeholder engagement.

The project sits in a well-established mining jurisdiction, and with a maiden Mineral Reserve estimate of 1.87Moz of Probable reserves, it supports a 10-year life of mine with an average production rate of 173,000 ounces per annum at all-in sustaining costs of US$1,017/oz.

We have identified several opportunities for potential reserve and resource growth and to further optimise the project, which will be assessed as part of the DFS. Of the US$23 million budgeted for Doropo in 2023, US$13.2 million was spent on finishing the PFS and completing the DFS drilling and fieldwork. Further drilling will be focussed on hydrology, metallurgy, geotechnics and sterilisation as we continue to progress the DFS. This de-risks the timeline to completion and further confirms our faith in the potential of Doropo to support a commercially viable project which will bring significant investment and job creation to northeastern Côte d'Ivoire.

EASTERN DESERT EXPLORATION BLOCKS (Egypt)

Model mining exploitation agreement

The Ministry of Petroleum & Natural Resources has been clear in its vision to create a thriving mining industry for the benefit of Egypt and its people. Centamin shares this vision and strongly believes that mining can fulfil its true potential in Egypt through employment, education and training, and direct financial and infrastructure investment to support Egypt's target for the mining industry to contribute 5% of the country's GDP by 2030.

On 20 July 2023 we agreed the framework for the model mining exploitation agreement ("MMEA") in principle with the Egyptian Ministry of Petroleum & Natural Resources and the Egyptian Mineral Resources Authority. The MMEA sets out the legal and fiscal framework that will apply to commercial discoveries made on the highly prospective c.3,000km² of ground awarded to Centamin in 2021 for exploration in the Eastern Desert of Egypt, referred to as the EDX blocks. Following routine Egyptian government and legal procedures, the MMEA will be ratified as a Special Law by the Arab Republic of Egypt in late 2023.

The MMEA terms are comparable to other jurisdictions with international, modern mining codes. The MMEA does not apply to the 160km² Sukari Gold Mine mining concession, which operates independently under the Sukari Concession Agreement, ratified by parliament under Egyptian Law No. 222 of 1994.

Exploration

Drilling commenced in Q2 2023 at our EDX Nugrus block. The Nugrus block is adjacent to the Sukari Mining Concession, sitting within 30km of the Sukari processing plant. The 10,000 metre drill programme is focussed on seven priority targets identified from the initial regional exportation programmes. To date, 3,000 metres have been drilled with assay results due later in H2 2023. In addition to the drilling, regional exploration will continue at Nugrus and Um Rus, including soil and generative rock chip sampling, with BLEG sampling commencing on the Nadj block in H2 2023.

EXPLORATION

Throughout H1 2023, we continued to advance our highly prospective exploration portfolio. At Sukari, a 20,000 metre drill programme was underway across the 160km² concession area. The programme focused on infill drilling of the resources that could generate satellite feed and testing strike extensions at Quartz Ridge, V-Shear East, Wadi Alam and the new Arc prospect located east of Sukari.

At Doropo, reverse circulation and core drilling activities were focused on resource infill drilling for the DFS. In addition, the team completed 15,403 metres of auger drilling alongside continued soil sampling with the aim to generate further drill targets.

At ABC, exploration was focused on testing extensions along the strike to confirm continuity of mineralisation with trenching undertaken on the Windou permit which generated several new drill targets. On the Kona permit, which is where the current Mineral Resource is located, a 11,500 metre RC programme was completed testing the Lolosso structure between Kona Central and Kona South and to the north and south. Moving forwards, we may undertake a provisional financial evaluation of the current resource before undertaking any further fieldwork.

OUTLOOK

Centamin is well positioned with guidance for 2023 unchanged. We are on track to achieve the midpoint of the production range, while continuing to progress our key projects that will unlock the full potential of our portfolio.

I would like to commend our workforce for their commitment, professionalism and passion. Their operational excellence has enabled us to deliver another strong half, building on our operational track record and delivering our strategy. I would also like to thank our local communities, partners and wider stakeholders for their support and shared vision.

We look forward to a busy second half of news flow, as we continue to deliver on our commitments and progress towards our vision of being a multi-asset, multi-jurisdictional, responsible producer.

CFO FINANCIAL REVIEW

(H1 2023 vs H1 2022)

We are pleased to report material improvements across most of our key financial metrics including revenue, EBITDA, profit after tax, operating cash flow and free cash flow. The strength of these results during a period of elevated capital investment, is testament to our prudent long-term approach to capital allocation and cost management.

H1 2023 has delivered strong operating cash flow of US$172 million, the highest in five interim periods. We generated positive Group free cash flow of US$19 million, after Sukari profit share distribution of US$46 million to our Egyptian partner, EMRA, and US$46 million to Centamin, and US$18 million spent advancing our organic growth pipeline at Doropo (Côte d'Ivoire), EDX (Egypt) and ABC (Côte d'Ivoire).

FINANCIAL PERFORMANCE

Revenues increased YoY by 11% to US$426 million, from annual gold sales of 219,353 ounces, up 8%, at an average realised price of US$1,936/oz, also up 3% YoY. Due to timing of gold shipments, a total of 14,692 ounces of unsold gold bullion was held at Sukari as at 30 June 2023, equivalent to US$28 million.

The Group adjusted EBITDA was US$193 million, at a 45% EBITDA margin, principally driven by:

• 8% increase in gold production, as scheduled, at a 3% higher average realised gold price YoY; in addition to:
  • a marginal 1% increase in the combined open pit and underground material mined, some of which has been capitalised to mining properties as a waste stripping asset, and
  • lower fuel prices and lower fuel consumption, offset by higher volumes, has resulted in a net US$8 million savings against budget, predominantly driven by the integration of solar power generation
  • Profit before tax increased by 36% to US$115 million, due to the factors below, with basic EPS increasing by 7% to 7.89 US cents
• 11% increase in revenue, in line with increased gold sales
• a significant increase in finance income and other income:
  • due to the volatility of mainly the Egyptian pound ("EGP") currency, there was a US$4 million foreign exchange gain in H1 2023
  • rising interest rates in both Egypt and the United Kingdom resulted in a US$2 million increase in interest income from funds placed in term-deposit, offset by
• 20% increase in other operating costs, predominantly due to a 9% increase in royalties paid
• 8% increase in greenfield exploration and evaluation expenditure, as budgeted, and
• 4% increase in cost of sales, marginally lower than budget

STRINGENT COST MANAGEMENT

Globally cost inflation remains high and central banks continue to tighten monetary policy in response. Our judicious approach to forecasting and stringent cost management has allowed us to deliver costs within our guidance last year and we remaining on track to meet 2023 guidance.

Cash costs of production in H1 2023 were US$187 million, a 1% improvement YoY and below our internal forecasts. This is primarily due to lower fuel prices and lower fuel consumption ( due to the integration of solar and our focus on operational efficiency gains,) partially offset by a 2% YoY increase in total material mined. Unit cash costs of production were US$849/oz produced, a 9% improvement YoY, driven by higher production volumes.

AISC in H1 2023 were US$269 million, an 8% improvement YoY, reflecting lower sustaining capex in the period offset by increased corporate costs due to non-recurring legal fees associated with the debt facility and gold protection programme. Unit AISC was US$1,228/oz sold, a 15% improvement YoY, driven by higher sales volumes. Importantly, our AISC margin is US$708/oz up 66% YoY.

Good progress continues to be made on our multi-year cost-savings programme with a cumulative US$143 million of our US$150 million target of cost savings by the end of 2023.

STRONG FINANCIAL POSITION

As of 30 June 2023, Centamin had cash and liquid assets of US$161 million, including 14.7koz of gold inventory waiting to be shipped. From a liquidity standpoint, the US$150 million sustainability-linked revolving credit facility remains available and undrawn.

CAPITAL INVESTMENT

This year is a period of significant reinvestment in the Sukari mine with an elevated level of gross capex of US$273 million budgeted for 2023. This includes US$48 million of sustaining capitalised deferred stripping. As a number of studies and multi-year projects move towards completion, we expect the capex to reduce from 2024 and beyond. These projects underpin our confidence in the long-term potential of Sukari.

H1 2023 gross capital expenditure was US$108 million, including commissioning the underground paste-fill plant, continued contracted waste-stripping programme, new underground equipment purchases, underground development, open pit equipment rebuilds, and construction of the North Dump Leach facility. Total sustaining capex was US$50 million, including US$10 million on deferred stripping, and non-sustaining was US$58 million. We had expected a higher capex spend in H1 but due to minor changes in scheduling, this has been moved to H2 2023 and we remain on track to meet 2023 guidance.

Gold Price Protection Programme

Centamin purchased put options for 240,000 ounces of gold at a strike price of US$1,900/oz. The put options mature at a rate of 20,000 ounces of gold per month, for the twelve months from July 2023 to June 2024^[2]. This is a cash-settled programme, not involving physical gold delivery.

The programme provides the Company protection should the average monthly gold price fall below the US$1,900/oz strike price, while allowing us to retain full exposure to any upside in the gold price above this level. As detailed above, this programme aligns with a period of elevated capital investment at Sukari, and gives us further financial flexibility to pursue the Company's strategy of delivering growth and returns to shareholders.

We were able to lock-in attractive pricing for put options, for a total premium paid of US$6.1 million which was funded from the Group's cash position.

Interim dividend

Consistent with the Company's stated commitment to shareholder returns, the Board declares an interim dividend of 2.0 US cents per share (US$23 million) for the period ended 30 June 2023. As per the dividend policy, this distribution is in line with the commitment to return a minimum of 30% of Group free cash flow before growth capex³ to shareholders in cash dividends. In consideration of the below factors, and reflecting the Board's confidence, a total of 56% of H1 2023 Group free cash flow before growth capex will be distributed to shareholders on 29 September 2023:

• Centamin is in a financially robust position with US$161 million in cash and liquid assets
• The US$150 million sustainability linked revolving credit facility remains undrawn as a result of H1 2023 growth capex being funded from cash flow
• The gold price protection programme limits the revenue downside risk below US$1,900/oz gold price
• The Company is operationally and financially well positioned for a stronger H2 2023, in line with plan

The interim dividend is calculated by the following:

Please refer to the Dividend Declaration announcement and or the website (www.centamin.com/investors/shares-dividends/dividend-information/) for further detail including the interim dividend timetable.

OUTLOOK

Financially, we expect a stronger second half of 2023 driven by higher production volumes and supported by our gold price protection Programme, should the gold price move below US$1,900/oz. Meanwhile, our focus on continuous improvement means we remain fully focused on managing the bottom line of the business so that we can maximise the value at Sukari and deliver growth and diversification combined with sustainable stakeholder returns.

ROSS JERRARD
CFO

26 July 2023

PRIMARY STATEMENTS HIGHLIGHTS

Revenue from gold and silver sales for the period increased by 11% year-on-year to US$426 million (2022: US$382 million) with a 3% increase in the year-on-year average realised gold price to US$1,936 per ounce sold (2022: US$1,872 per ounce sold) complimented by an 8% increase in gold ounces sold to 219,353 ounces (2022: 203,587 ounces).

Cost of sales represents the cost of mining, processing, refining, transport, site administration, depreciation, amortisation and movement in production inventories. Cost of sales is up 4% year-on-year to US$268 million, mainly because of:

• 16% increase in depreciation and amortisation charges year-on-year from US$68 million to US$79 million (+ve). This increase was mainly due to:
  • US$137 million additions to property, plant and equipment (excl. capital work in progress) which increased the depreciation and amortisation charges; in addition to higher gold production year-on-year; partially offset by
• a 2% decrease (US$4 million) in total mine production costs from US$192 million to US$188 million (-ve), primarily due to the following drivers:
  • an 11% decrease in processing costs (US$11 million) (-ve). The decrease was driven by general price decreases and stabilisation on fuel and other consumables as well as the consumption reduction due to the solar power coming online. Diesel fuel is mainly consumed at Sukari for the process plants power generation
  • a 20% decrease in administration costs (US$5 million) (-ve); offset by
  • a 17% increase in open pit mining costs (US$10 million) (+ve)

Profit share payments during the year are reconciled against SGM's audited financial statements. Any variation between payments made during the year (based on the Company's estimates) and the SGM's audited financial statements, may result in a balance due and payable to EMRA or advances to be offset against future distributions. SGM's 30 June 2022 financial statements have been audited and signed off, the 30 June 2023 financial statements are currently under audit.

Refer to note 1.3.1.2 in the 2022 Annual Report for details of the treatment and disclosure of the EMRA profit share.

CAPITAL EXPENDITURE

The following table provides a breakdown of the total capital expenditure of the Group:

1. Non-sustaining capital expenditure included further spend on the solar plant, underground paste-fill plant and the Capital Waste Stripping. Non-sustaining costs are primarily those costs incurred at 'new operations' and costs related to 'major projects at existing operations' that will materially benefit the operation.
2. Reclassified from operating expenditure.

EXPLORATION EXPENDITURE

The following table provides a breakdown of the total exploration expenditure of the Group:

Exploration and evaluation expenditure comprises expenditure incurred for exploration activities primarily in Côte d'Ivoire and in the Egypt greenfield permit areas. Greenfield exploration and evaluation costs (excluding Burkina Faso) increased by US$2 million or 14% as the exploration and evaluation work at the two Côte d'Ivoire sites advanced, more significantly at the Doropo site. Some drilling work has also started at Nugrus, one of the new Egypt permit areas. The brownfield capitalised exploration costs on the Sukari concession area increased by US$3 million or 79% year on year due to the exploration and evaluation work and related activities at the Sukari permit areas increasing in the period.

The spend in Burkina Faso is mainly on key services and other regulatory obligations required as the process to formally exit the project is currently underway.

SUBSEQUENT EVENTS

Interim dividend

The Directors have declared an interim dividend of 2.0 US cents per share on Centamin Plc ordinary shares (totalling approximately US$23 million). The interim dividend for the half year period ended 30 June 2023 will be paid on 29 September 2023 to shareholders on the register on the Record Date of 1 September 2023.

Gold price protection programme

Centamin purchased a further six months of put options for 120,000 ounces of gold at a strike price of US$1,900/oz. The put options mature at a rate of 20,000 ounces of gold per month, for the six months from January to June 2024. This is a cash-settled programme, not involving physical gold delivery.

The programme provides the Company protection should the average monthly gold price fall below the US$1,900/oz strike price, while allowing us to retain full exposure to any upside in the gold price above this level. As detailed above, this programme aligns with a period of elevated capital investment at Sukari, and gives us further financial flexibility to pursue the Company's strategy of delivering growth and returns to shareholders. The premium for the programme extension was US$3.6 million.

Other than as noted above, there were no other significant events occurring after the reporting date requiring disclosure in the financial statements.

NON?GAAP FINANCIAL MEASURES

1) EBITDA and adjusted EBITDA

EBITDA is a non?GAAP financial measure, which excludes the following from profit before tax:

• Finance costs
• Finance income
• Depreciation and amortisation

Management considers EBITDA a valuable indicator of the Group's ability to generate liquidity by producing operating cash flow to fund working capital needs and capital expenditures. EBITDA is also frequently used by investors and analysts for valuation purposes whereby EBITDA is multiplied by a factor or 'EBITDA multiple' that is based on an observed or inferred relationship between EBITDA and market values to determine a company's approximate total enterprise value. EBITDA is intended to provide additional information to investors and analysts and does not have any standardised definition under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

EBITDA excludes the impact of income from financing activities and taxes, and therefore is not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Other companies may also calculate EBITDA differently. The following table provides a reconciliation of EBITDA to profit for the year before tax.

Adjusted EBITDA removes the effect of transactions that are not core to the Group's main operations, like adjustments made to normalise earnings, for example profit on financial assets at fair value through profit or loss, impairments of property, plant and equipment, non-current mining stockpiles and exploration and evaluation assets.

Reconciliation of profit before tax to EBITDA and adjusted EBITDA:

1. Adjustments made to normalise earnings for example profit on financial assets at fair value through profit or loss, impairments of property, plant and equipment, non-current mining stockpiles and exploration and evaluation assets.

2) Cash cost of production per ounce produced and sold and all-in sustaining costs ("AISC") per ounce sold calculation

Cash cost of production and AISC are non-GAAP financial measures. Cash cost of production per ounce is a measure of the average cost of producing an ounce of gold, calculated by dividing the operating costs in a period by the total gold production over the same period. Operating costs represent total operating costs less sustaining administrative expenses, royalties, depreciation and amortisation. Management uses this measure internally to better assess performance trends for the Company as a whole. Management considers that, in addition to conventional measures prepared in accordance with GAAP, certain investors use such non-GAAP information to evaluate the Company's performance and ability to generate cash flow. Management considers that these measures provide an alternative reflection of the Group's performance for the current year and are an alternative indication of its expected performance in future periods. Cash cost of production is intended to provide additional information, does not have any standardised meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. This measure is not necessarily indicative of operating profit or cash flow from operations as determined under GAAP. Other companies may calculate these measures differently.

Reconciliation of cash cost of production per ounce produced:

(1) The movement in inventory on ounces produced is only the net movement in mining stockpiles and ore in circuit while the movement in ounces sold is the net movement in mining stockpiles, ore in circuit and gold in safe inventory.

A reconciliation has been included below to show the cash cost of production metric should gold sold ounces be used as a denominator.

Reconciliation of cash cost of production per ounce sold:

(1) The movement in inventory on ounces produced is only net the movement in mining stockpiles and ore in circuit while the movement in ounces sold is the net movement in mining stockpiles, ore in circuit and gold in safe inventory.

Reconciliation of AISC per ounce sold:

(1) Includes refinery and transport.

3) Cash and cash equivalents, bullion on hand and gold and silver sales debtor

Cash and cash equivalents, bullion on hand, gold and silver sales debtor is a non-GAAP financial measure of the available cash and liquid assets at a point in time. Management uses this measure internally to better assess performance trends for the Company as a whole. Management considers that, in addition to conventional measures prepared in accordance with GAAP, certain investors use such non-GAAP information to evaluate the Company's performance and ability to generate cash flow and the measure is intended to provide additional information.

This non-GAAP measure does not have any standardised meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. This measure is not necessarily indicative of cash and cash equivalents as determined under GAAP and other companies may calculate it differently.

Reconciliation to cash and cash equivalents, bullion on hand, gold and silver sales debtor and financial assets at fair value through profit or loss:

The majority of funds have been invested in international rolling short-term interest money market deposits.

4) Free cash flow and adjusted free cash flow

Free cash flow is a non-GAAP financial measure. Free cash flow is a measure of the available cash after distributions to the Non-Controlling Interest ("NCI") in SGM, being EMRA, that the Group has at its disposal to use for capital reinvestment and to distribute to shareholders of the parent. Free cash flow is intended to provide additional information, does not have any standardised meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. This measure is not necessarily indicative of operating profit or cash flow from operations as determined under GAAP and other companies may calculate this measure differently.

(1) Adjustments made to free cash flow, for example acquisitions and disposals of financial assets at fair value through profit or loss, which are completed through specific allocated available cash reserve

Legal developments in Egypt

On 14 January 2023, Egyptian Law No. 32 of 2014 ("Law 32") was upheld as constitutional by the Egyptian Supreme Constitutional Court ("SCC"), having been under challenge since 2014.

SUMMARY

• Law 32 provides that third parties are prevented from lawfully challenging contractual agreements between the Egyptian government and an investor(s), such as the Sukari Gold Mine Concession Agreement ("Concession Agreement")
• The SCC judgment gives Centamin the right to request the Supreme Administrative Court ("SAC") to rule that the 2011 challenge to the Concession Agreement is now legally inadmissible on the basis that the original complainant had no capacity to bring the claim as he was not a party to the Concession Agreement
• As per the provisions of Egyptian Civil Procedures Law, Centamin's subsidiary, PGM, has submitted an application to the SAC to resume the Appeal proceedings and request the SAC to reject the original case in its entirety in accordance with the provisions of Law 32
• The SAC has set the hearing date for 2 September 2023
• Operations at the Sukari Gold Mine remain unaffected and continue as normal

There have been no material developments since the issuance of the 2022 annual report. For further detail please refer to Note 5.1 of the 2022 Annual Report.

PRINCIPAL RISKS AND UNCERTAINTIES

RISK MANAGEMENT

Centamin recognises that nothing is without risk. We believe a successful and sustainable business requires a robust and proactive risk management framework as its foundation. This is supported by a strong culture of risk awareness, encouraging openness and integrity, alongside a clearly defined appetite for risk. This enables the Company to consider risks and opportunities for more effective decision-making, delivery on our objectives and improve our performance as a responsible mining company. The Board has overall responsibility, supported by the Audit and Risk Committee, for establishing a framework that allows for the review of existing and emerging risks in the context of both opportunities and potential threats that inform the principal risks and uncertainties. These risks and opportunities inform the assessment of the future prospects and long-term viability of the Group, as shown in the Viability Statement of the 2022 Annual Report and are also considered when challenging the strategic objectives of the Company.

2022 was a year of extreme macroeconomic changes exacerbated by geopolitical pressures including the situation in Ukraine and the ongoing impacts of the COVID pandemic. Whilst as a business we were able to successfully manage the operational considerations of the pandemic, we have felt the financial pressures as every government, business and individual has globally. The 2022 Annual Report included updates to the principal and emerging risks driven by these pressures, with detail provided on these changes in the Risk Review of the 2022 Annual Report. There has been no change to the Principal and Emerging risks since then except for those highlighted below. We continue to feel the ongoing global impact of these increased financial pressures, which we continue to monitor, which has led to the introduction of the Gold Price Protection Programme, as highlighted in the CFO Financial Review. These downside protection mechanisms have changed the mitigations and ongoing strategy through H2 2023 for the financially focussed risks of Gold price, Global macroeconomic developments and Capital allocation & liquidity. When also considering the healthy financial position of the business, additional measures such as the focus on cost savings initiatives and the revolving credit facility, means we feel there is now sufficient financial flexibility to meet the Company's current and future financial commitments through 2023. In addition, regarding the Litigation risk we are awaiting the Supreme Administrative Court hearing, as highlighted in the Legal Developments in Egypt, to make the relevant updates to this risk.

The Directors confirm that a robust assessment of the principal, new and emerging risks impacting the Company has been undertaken which identified external, strategic and operational risks on a sliding scale depending on the level of influence over which the Company may have on the factors which can impact the risk. For further detail please refer to the Risk Review within the 2022 Annual Report and 2022 Sustainability Report, published on the Company's website: www.centamin.com.
