Chief Executive Officer's Review

Delivering on our key opportunities in African energy

Dear fellow shareholders,

I would like to welcome you to our 11th Annual Report as a listed company, marking more than a decade of Savannah delivering Projects that Matter in Africa. This year's letter follows a similar format to those of recent years. The first section discusses the global business environment in 2024. The second section discusses our Company's continued strong financial, operational and sustainability performance in 2024. The third section discusses key business priorities for the year ahead. The last section talks about the "how" and the "why" we see the African energy transition evolving and discusses the relevance of our hydrocarbon AND renewable energy strategy.

Before turning to the first section, I would like to draw your attention to two guest authored articles in this year's Annual Report. The first (on page 17) is authored by Hon. Wale Edun, Minister of Finance and Coordinating Minister of the Economy of Nigeria and discusses his views on "Unlocking Opportunities Across the Economy" (originally published in Forbes Africa). The second article (on pages 27 to 33) is authored by Daniel Yergin, Peter Orzag and Atul Arya, "The Troubled Energy Transition" (originally published in Foreign Affairs), who make an articulate argument that we are now experiencing an "energy addition" as opposed to an "energy transition", with their critical observation that "throughout history, no energy source, including traditional biomass, has declined globally in absolute terms over an extended period". We are extremely grateful to our distinguished guest authors for their contributions.

I would also like to highlight on pages 8 to 15 a discussion of "Why we do what we do", which focuses on our corporate purpose and the associated core beliefs which serve to underpin our strategy and business model. I really believe that this section is essential reading for anyone seeking to understand our Company.

2024 Global Business Environment

The global economy remained relatively stable in 2024. Although the OECD1, and Africa2 recorded different GDP growth rates, both showed a similar year-on-year trend of consistent growth. Oil prices remained broadly flat, with the Brent crude benchmark declining by a modest 1.2%.3 Global LNG prices fell by approximately 15% (although they remained elevated by historical standards).4 Results were burdened by weak refining5,6 and chemicals margins7,8 in 2024, as supply significantly outpaced demand growth. Developed economies experienced a notable decline in inflation from an average of 4.8% in 2023 to an estimated 2.6% in 20242, while inflation across African nations remained persistently high at 16.6% in 2023 versus 16.1% in 2024.

Against this backdrop, Nigeria saw a significant increase in inflation in 2024 (29% versus 25% in 2023)9 alongside a substantial 40% depreciation of the Naira against the US$.10 This was largely driven by the transitional impact of market-oriented government policy changes, including a removal of fuel subsidies and the switch from a managed to a floating exchange rate regime.11 We believe that these policies, together with the Government's stated objective to increase oil production (which contributes approximately 65% of Government revenue and 85% of total exports12) by approximately one-third,13 their intention to impose cost reflective power tariffs, and a likely privatisation programme of select Government assets, have the potential to transform the country's economy. Early indications have been encouraging; the World Bank reported that Nigeria saw its strongest growth in a decade in Q4 2024, with a 4.6% year-on-year expansion, leading to an annual growth rate of 3.4% in 2024, the highest since 2014;14 foreign exchange reforms have helped stabilise the Naira at around NGN 1,485 (at the time of writing) to the US$15; and in April and May 2025, Nigeria's credit rating was upgraded to "B" by Fitch Ratings16, and to "B3" by Moody's respectively. In July 2025, in its latest Article IV Consultation, the International Monetary Fund ("IMF") formally praised Nigeria for implementing "major reforms over the past two years" that have improved macroeconomic stability and resilience.17

In 2024, the seven energy supermajors - BP, Chevron, ConocoPhillips, Eni, ExxonMobil, Shell and TotalEnergies (the "Supermajors") - reported a combined profit of US$95.7 billion, representing a 26% year-on-year decline, despite a 6% increase in combined upstream production volumes.18

The corporate performance of the Supermajors was influenced not only by oil production but also by lower gas prices, weaker refining and petrochemical margins, and the corporate mix of business lines, including lower carbon.19 There was a marked divergence between the performance of the US majors and their European counterparts; US companies saw net income fall by 11%, alongside an 11% increase in production volumes, whereas the European majors experienced a 43% decline in net income with only a 1% increase in production.18 This disparity was driven, at least in part, by differing strategic approaches to the energy transition. US companies have typically: (1) invested more heavily in hydrocarbons and less in renewables or lower-carbon divisions than their European peers; and (2) maintained stronger capital discipline with respect to expected investment returns. At the time of writing a new consensus appears to have emerged, at least for now, that more closely aligns with the US approach.20, 21, 22

However, due to the long investment lead times associated with energy projects, it may take several years before the relative performance differential is fully resolved.

Savannah's 2024 Performance

Savannah's financial performance in 2024 was ahead of guidance for the year. We reported Total Revenues(a) of US$258.9 million (versus guidance of "greater than US$245 million" and 2023: US$260.9 million versus guidance of "greater than US$235 million"), Operating and administrative expenses(g) of US$71.0 million (versus guidance of "less than US$75 million" and 2023: US$68.8 million) and Adjusted EBITDA(d) of US$181.2 million (2023: US$184.1 million). Our Adjusted EBITDA(d) margin remained industry leading at 70% when compared to the Supermajors' average margin of 22.3% in 2024.23

At the Nigerian business unit level, we recorded Adjusted EBITDA(d) of US$210.4 million, broadly in line with last year (2023: US$213.9 million), and an Adjusted EBITDA(d) margin of 81%. The US$29.2 million difference between the Group and our Nigerian business Adjusted EBITDA(d) numbers largely reflects the central costs of running the business, the investments we are making in our pre-revenue power business and various transaction costs as we progress our significant future growth plans.

We demonstrated strong operational performance in 2024. Average gross daily production was 23.1 Kboepd for FY 2024, broadly in line with the prior year (FY 2023: 23.6 Kboepd), of which 88% was gas (FY 2023: 91%). We maintained a 97% uptime at our Uquo CPF, with downtime a result of planned maintenance. In 2024, 88% of our revenue stream was derived from fixed price gas sales agreements with no cyclical exposure to oil or international gas prices. Over the last seven years (2017 - 2024) our Nigerian business has achieved an annualised Total Revenues(a) Compound Annual Growth Rate ("CAGR") of 9%. This Total Revenues(a) growth compares favourably to the long-term trend CAGR of the wider UK stock market constituents of 3%.24 We currently supply gas to support both approximately 17% of Nigeria's available thermal power generation capacity (up from approximately 10% at the time of acquisition), and approximately 18% of Nigeria's annual cement production.25 We are clearly performing a critical service to the Nigerian economy.

In 2024 we continued to progress our pipeline of pre-revenue power projects with our principal focus being on the up to 250 MW Parc Eolien de la Tarka wind farm project in Niger and the up to 95 MW Bini a Warak hybrid hydroelectric and solar project in Cameroon.

We maintained our strong focus around safe operational delivery in 2024, recording an exceptional LTIR of zero and a TRIR of zero per 200,000 working hours. Our performance against key sustainability metrics remained equally industry-leading. At 5.7 kg CO2e/boe, our carbon emissions were 73% lower than the industry average of 21.3 kg CO2e/boe26, registering a 47% reduction year-on-year. Additionally, our senior management female gender diversity was broadly in line with the prior year at 32%, while our local employee ratios in our countries of operation were maintained at 99% for Nigeria and 100% for Niger.

We continued to focus on providing training programmes to support the ongoing skills and knowledge development of our workforce, with a more than 30% increase in training hours in 2024 to an average of 75 hours per employee. This includes an almost three-fold increase in HSE training hours across all levels of the organisation, in line with our strong commitment to health and safety. In addition to the "Safe Start", "Finish Strong" and "Eye Injury Prevention" internal training campaigns rolled out at our Nigerian operational sites during the year, personnel completed a focused HSE training programme in 2024, using external consultants to cover core topics, such as our life saving rules, safe systems of work, process safety, fire, first aid and permit to work procedures.

Nigeria

In March 2024, we signed a sale and purchase agreement to increase our effective ownership of the Stubb Creek oil and gas field in Nigeria from 51% to 100%, through the acquisition of our Nigerian affiliate Universal Energy Resources' joint venture partner, SIPEC. This acquisition, completed post-year end in March 2025, increased Savannah's Reserves and Resources base by approximately 47 MMboe from 160 MMboe to 207 MMboe (on a pro-forma basis as at end of December 2024).27  Following completion, we are now implementing an up to 18-month expansion programme to increase the processing capacity of the Stubb Creek facilities. It is anticipated that this will lead to Stubb Creek gross production increasing from an average of 2.7 Kbopd in 2024 to up to 4.7 Kbopd. Post-year end, Stubb Creek average monthly production was 3.3 Kbopd , an increase of approximately 24% compared to the average production for 2024. In parallel, we are evaluating an alternative, lower capex option that could deliver a faster production ramp up, with plateau production sustained for a longer period at a slightly lower rate than under the original expansion programme.

Post-year end, we announced a 29% increase in Stubb Creek gross 2P oil Reserves, based on the latest Nigeria CPR prepared by McDaniel as at 31 March 2025, compared to the previous March 2024 Nigeria CPR prepared by CGG. The increase is due to an improved ultimate field recovery factor, as determined through the implementation of enhanced field monitoring protocols and advanced reservoir modelling. The entire acquisition consideration was funded through a non-recourse debt facility provided by The Standard Bank of South Africa, and we estimate the acquisition to be over US$150 million accretive to the Company's NAV10, based on the acquired oil reserves alone. Additionally, the SIPEC Acquisition also secures significant additional feedstock gas (226 Bscf) available for sale to our Accugas subsidiary.

Our Uquo gross 2P gas Reserves as at 31 March 2025 increased by 21% in the latest Nigeria CPR prepared by McDaniel compared to the previous March 2024 Nigeria CPR prepared by CGG. The increase is due to the conversion of one reservoir from Contingent Resources to Reserves and an increase of Reserves in one reservoir based on production data and analysis.

Throughout 2024 we continued to progress the Uquo compression project. Post-year end, we successfully completed this important project, safely and approximately 10% under the original budget of US$45 million, which is expected to allow us to maximise the production from our existing and future gas wells.

The trade receivables balance at year-end 2024 was US$538.9 million (31 December 2023: US$389.9 million) and post-year end has reduced 9% to US$493.3 million. It relates primarily to amounts due under various gas sales agreements in Nigeria. The power sector in Nigeria continues to face very challenging liquidity conditions, which have impacted payment timelines across the value chain. We continue to pursue constructive discussions with our customers to implement structured payment plans to reduce this receivable balance.

Niger

In 2024 we continued to seek to progress the 35 MMstb (Gross 2C Resources) R3 East oil development in South East Niger. The Niger-Benin oil export pipeline, now fully operational, provides a potential route to international markets for crude oil produced from the R1234 contract area of our subsidiary, Savannah Energy Niger SA. Post year-end the Company has sought to actively engage with the Government of Niger around our forward work programme plans in country. Subject to a satisfactory agreement being reached with the Government, our subsidiary is considering commencing a four-well testing programme and/or a return to exploration activity in the R1234 PSC contract area in 2026/27. The R3 East development plan, itself, has been significantly re-worked since the last published Niger CPR of December 2021, with a plateau production rate of around 10 Kbopd now assumed (previously 5 Kbopd). We have updated our internal management estimates of the potential PV10 value (on an unrisked basis) at an asset level basis for R3 East to US$184.4million (vs the last CPR asset value estimate of US$150 million). Assuming a successful well test programme is conducted, we would look to accelerate plans to commence commercial oil production from the R3 East Area and intend to incorporate the data acquired into our field development plan.

Our 250 MW Parc Eolien de la Tarka wind farm project made significant progress in 2024, with the Minister of Energy confirming that the project is on the Government's list of priority projects. We are continuing to seek to negotiate outline terms in relation to the project's proposed power purchase agreement and continue to work on the project in close collaboration with two leading development institutions (the IFC, part of the World Bank Group, and the DFC). Our ESIA scoping report, which found there were no endangered flora or fauna detected, has been validated by the Niger authorities and consultants are currently working on the additional studies required to complete the full ESIA. A framework to identify and compensate impacted landowners has also been established.

Savannah is also progressing a large-scale solar project in Niger, comprising two photovoltaic solar power plants, expected to be located within 20 km of the cities of Maradi and Zinder, in southern Niger. Each plant is expected to have an installed capacity of up to 100 MW. In March 2024, we presented preliminary commercial and technical proposals to the Government of Niger. To be clear the Niger solar projects are of lower priority than Parc Eolien de la Tarka and Savannah does not expect significant development activity to occur on these projects prior to financial close being reached on Parc Eolien de la Tarka.

Cameroon

Substantial progress was made on Savannah's Bini a Warak hybrid hydroelectric and solar project during 2024. Following the approval of the proposed redesign given by the Minister of Water and Energy in late 2023, the project now includes 40 MW of photovoltaic solar, increasing its combined solar and hydro installed power generation capacity from 75 MW to 95 MW.

Hydropower production will adapt to photovoltaic solar production levels, enabling a combined stable level of energy generation throughout the day.

Negotiations with the Government of Cameroon are at an advanced stage regarding a Joint Development Agreement to replace the Memorandum of Agreement signed in April 2023. This, once signed, will secure the terms under which Savannah will collaborate with the Government to develop the project. Prior to financial close, we currently expect to reduce our ownership interest in the Bini a Warak project by around 50%, so as to introduce additional equity partners.

The project is expected to generate clean and stable power for Cameroon's northern region, increasing the region's generation capacity by over 50%. Financial close is currently anticipated in Q3 2028, with first power from the solar unit targeted two years thereafter and the hydropower unit commissioned approximately four years after project sanction.

Arbitral Proceedings

Savannah Chad Inc ("SCI"), commenced arbitral proceedings in 2023 against the Government of the Republic of Chad in response to the March 2023 nationalisation of SCI's rights in the Doba fields in Chad, and other breaches of SCI's rights. Another wholly owned subsidiary, Savannah Midstream Investment Limited ("SMIL"), commenced arbitral proceedings in 2023 in relation to the nationalisation of its investment in TOTCo, the Chadian company which owns and operates the section of the Chad-Cameroon pipeline located in Chad. SMIL has also commenced arbitral and other legal proceedings for breaches of SMIL's rights in relation to COTCo, the Cameroon company which owns and operates the section of the Chad-Cameroon pipeline located in Cameroon. We currently expect these arbitral proceedings to be concluded in the first half of 2026.

SCI and SMIL are claiming in excess of US$775 million (plus interest currently estimated at in excess of US$170 million and costs) for the nationalisation of their rights and assets in Chad.29 SMIL has a claim valued at approximately US$330 million (plus interest which is currently estimated at in excess of US$60 million plus costs) for breaches of its rights in relation to COTCo.30 Whilst the Government of the Republic of Chad has acknowledged SCI's and SMIL's right to compensation, no compensation has been paid by the Government of the Republic of Chad to date. Savannah remains ready and willing to discuss with the Government of the Republic of Chad an amicable solution to the disputes. However, in the absence of such discussions, SCI and SMIL intend to vigorously pursue their rights in the arbitrations.

SCI is involved in further arbitral proceedings in which designates of Société des Hydrocarbures du Tchad allege breaches by SCI of the Doba fields joint operating agreement.31 SCI is defending the claims vigorously. We currently expect these arbitral proceedings to be concluded in Q3 2026.

South Sudan

In 2024, we sought to progress our previously announced proposed acquisition of the PETRONAS assets in South Sudan, a large scale transaction which would have seen subsidiary of Savannah acquiring significant interests in a portfolio of assets which produced an estimated 145 Kbopd (gross) of crude oil on 2023.32 Post year-end, in March 2025, we announced that we had terminated existing discussions relating to the transaction, so as to enable the Company's shares to be restored to trading on AIM (due to their suspension given the transaction had been deemed a Reverse Takeover under the AIM rules which the Company is subject to). While we would not rule out returning to pursue energy projects in South Sudan in the future, at the time of writing the pursuit of such projects is not viewed as a priority by the business.

Power Division

We have repositioned our Power Division business model, to pursue operating asset opportunities in both the thermal and renewable energy spaces alongside interests in large scale renewable energy development projects, while maintaining our disciplined approach that all projects must meet similar risk-adjusted investment return thresholds. Against this backdrop, post-year end, we were pleased to announce our planned entry into the Bujagali, Mpatamanga and Ruzizi III hydropower projects through the acquisition of Norfund's interest in Klinchenberg. Bujagali is a flagship East African power plant with an excellent 13-year operating and payment track record. Mpatamanga and Ruzizi III are advanced-stage developments which are expected to generate highly competitively priced electricity in their respective countries for the benefit of over 30 million people. Each project has a strong partnership group which we are excited to join.

Key Business Priorities for 2025 and H1 2026

We have nine key focus areas in our business over the course of the next 12 months:

•   Delivering a further increase in our rate of Cash Collections(j) in Nigeria. In 2025 we expect to deliver a strong increase in Cash Collections(j) even when set against the 13% CAGR which has been achieved since the announcement of our acquisition of the Nigerian business in 2017;

•   Completion of the refinancing of our principal Nigerian debt facilities. As at 31 December 2024, our Nigerian subsidiary, Accugas Limited, had a US$ denominated debt facility with an outstanding balance of approximately US$212.3 million. Post-year end we increased the Transitional Facility to NGN772 billion (approximately US$500 million) and expect to fully convert the remaining Accugas US$ Facility into Nigerian Naira by the end of 2025;

•   Completion of the SIPEC Acquisition. This highly accretive acquisition (see above discussion) was completed in March 2025. The deal was estimated to be US$201 million accretive to NAV and increased Group gross 2P Reserves and gross 2C Resources by c. 30%;

•   Commencement of the Stubb Creek expansion project. At the time of writing, we are in the process of implementing an expansion at the Stubb Creek processing facilities. It is anticipated that, inter alia, the completion of this project in 2026 would see an increase of more than 80% in near-term free cash flow from the field in 2026-27;

•   The advancement of our arbitral proceedings.33 As discussed previously, SCI and SMIL have claims valued in excess of US$1 billion in aggregate in the Chad disputes with the Paris-based legal arbitral proceedings scheduled to conclude in the first half of 2026 ;

•   The commencement of the safe and successful drilling of our Uquo development and exploration wells. The Uquo NE development well is expected to increase the field's productive capacity, while the Uquo South exploration well would target a 131 Bscf Gross Unrisked GIIP prospect;

•   The potential advancement of our R3 East development in Niger and/or a return to exploration activity in the R1234 PSC area. We are continuing to seek to progress the 35 MMstb (Gross 2C Resources) R3 East oil development in South East Niger, subject to satisfactory stakeholder agreements being entered into (in parallel with consideration to recommence exploration activity, all of which is subject to reaching suitable stakeholder agreements);

•   The refinement of our power sector business model. We are actively reviewing opportunities in both the thermal and renewable power sectors, following the repositioning of our power sector business model. We were pleased to announce post-year end our planned entry into three East African hydropower projects; and

•   The delivery of further transformational acquisitions. The African energy sector offers attractive M&A market dynamics, with, for example, large divestment programmes by major and national oil companies in the hydrocarbon sector and by private equity firms in the power sector. Savannah is strongly positioned to continue to participate in these divestment programmes, given our operating capabilities, regional reputation and access to capital. We continue to view mergers and acquisitions as a core driver of potential future value creation and are actively pursuing opportunities across both the hydrocarbon and power sectors. Our business development pipeline is sufficiently large that we are confident of announcing further transaction(s) over the course of the next 24 months. Post-deal we would expect to act as a strong asset steward, delivering better underlying operational performance and improvements in unit carbon intensity (within the limitations of the underlying assets) compared to the previous asset owners.

UK Public Markets Landscape

The UK equity market continues to face a number of structural challenges. Industry data indicates that UK equity funds have experienced sustained net outflows for several consecutive years, with cumulative redemptions in the tens of billions of pounds over this period. Over the past two decades, UK pension funds have also materially reduced their allocation to UK-listed equities, from levels of around 50% in 2000 to single-digit percentages today.34 As a result, UK-listed companies currently trade at valuation multiples that are materially lower than many of their international peers.35 The UK Government and financial regulators have acknowledged these trends and have stated their intention to implement reforms designed to strengthen the attractiveness of the UK's capital markets and to encourage greater investment in domestic equities.

Savannah has actively engaged with the London Stock Exchange in connection with its consultation paper "Shaping the Future of AIM", contributing to this reform dialogue. Savannah's particular focus has been on the operation of AIM Rule 14 relating to share suspensions, under which companies may be required to suspend trading for extended periods when undertaking large-scale transactions deemed to be reverse takeovers. The Company believes that such transactions can represent important opportunities for value-accretive growth; however, the potential for prolonged suspension periods can deter companies - particularly those operating in jurisdictions where governmental approvals are protracted - from pursuing such opportunities.

While the Board remains supportive of the Shaping the Future of AIM initiative and is hopeful that it will deliver reforms enhancing AIM's suitability for high-growth companies, it also recognises the ongoing market challenges noted above, including those relating to cost of capital. Further the Board is concerned that, given the Company's strategy and ambitions, were AIM Rule 14 not to be significantly amended, there is a risk that the Company's shares could be subject to another prolonged period of share suspension in relation to a future reverse takeover. The Company continues to evaluate a range of potential corporate transactions which, if pursued, could be classified as reverse takeovers under the AIM Rules. Accordingly, the Board considers that further reform of AIM Rule 14 would be beneficial in supporting the Company's growth strategy.

As part of its normal course of business, the Board has also initiated a review of the appropriateness of Savannah's current AIM quotation and the potential alternative options available to the Company, including the possibility of seeking admission to another recognised stock exchange. This review remains at an early and exploratory stage. There can be no certainty that it will lead to any changes to the Company's current market arrangements. The Company intends to engage with its investor base on this matter during the course of Q4 2025.

How We See the African Energy Transition

As in previous years' shareholder letters, I have chosen to discuss how we see the African energy transition. Before turning to discuss this, I feel it is important to emphasise that this is only one of several important contributing beliefs driving what Savannah does as a company. On pages 8 to 15 of the Annual Report we have outlined in detail "Why we do what we do". In that section we discuss our corporate purpose and associated core beliefs which serve to underpin our hydrocarbons AND renewable energy strategy and our business model. In simple terms, the section explains why energy poverty in Africa is the principal problem our Company is seeking to help solve and why we believe this problem is one of the most urgent and important problems facing the world today. I would urge any reader interested in further understanding our Company to read this section, especially if they are from a rich world background and perhaps less intuitively understand the realities of the everyday challenges facing the 429 million people in Africa who are defined by the World Bank as living in extreme poverty (i.e. have incomes of less than US$2.15/day).

Energy is critical to enabling and sustaining people's quality of life. My preferred chart for demonstrating this is below, which compares GDP per capita to power consumption per capita. As can be seen, people without access to energy are dramatically poorer than those with access to energy. For example, Niger is ranked 188 out of 193 on the UN Human Development Index36 ("UN HDI") with a GDP per capita of US$723 and power consumption per capita of 62 kWh.37 The United States of America on the other hand is ranked 17 out of 193 on the UN HDI with GDP per capita of US$85,810 and power consumption per capita of 12,551 kWh, 11,774% and 20,144% higher respectively. A similar pattern emerges when we look at the relationship between power consumption and other key quality of life barometers such as life expectancy and lifetime health outcomes.

Over 80% of today's global energy mix is provided by hydrocarbons with 53% of this provided by oil and gas.38 The scale of investment required to sustain the "status quo" global quality of life is immense. Global non-financial capital expenditures for the energy sector amount to 42% of all global capex.38 The world clearly, therefore, requires oil and gas today, and is prepared to pay vast amounts of money to enable this. The extent to which the world requires oil and gas in the future will depend on the absolute and relative rate of development of renewable energy and carbon mitigation technological improvements, and the absolute and relative rate of their adoption. In this regard, the quote by John Kerry (The former US Climate Change Envoy), which I have cited in my last four shareholder letters, remains pertinent - "I am told by scientists that 50% of the reductions we have to make by 2050 or 2045 are going to come from technologies we don't have yet."

While the pace of technological evolution and adoption may be argued to be generally faster today than in earlier periods, I believe that it is important to recognise that the global energy transition is likely to take a relatively long time. As demonstrated on page 25, previous energy transitions have taken 50+ years, and the modern renewable transition only began around 2015. Further, full displacement of the previous energy sources has not occurred in previous transitions (i.e. coal still provided approximately 28% of the global energy mix in 2024). Recent data for H1 2025 has seen more power generated worldwide from renewable sources that from coal for the first time ever.39

In this regard, when we look at the forecast future energy mix, there is currently a big difference between the trend case (i.e. what forecasters are suggesting will actually happen) versus the net zero 2050 case. Essentially the world appears to be on track to have around 52 - 54%40 of its energy mix in 2050 be provided by oil and gas, which, given likely energy demand growth over the course of the next 26 years, suggests that actual oil and gas demand is currently not on trend to fall significantly over the period.

The foregoing contrasts dramatically with the many net zero forecasts which generally see the total share of fossil fuel supply falling to just over 20% of the global energy mix by 2050.40

Further, it is likely that lower-income countries, where the ability to pay for renewable energy infrastructure is lowest and the need for low-priced energy to deliver life changing economic growth is highest, will see hydrocarbons form a much greater part of their energy mix in 2050 than in the developed world. This point is demonstrated well by the map on page 24. On average, only 57% of Africa's entire population has access to on-grid electricity, with the electricity access rate in our countries of active operations estimated at 71% for Cameroon, 20% for Niger and 61% for Nigeria.41 For much of Africa, the primary issue is around people being given access to reliable and affordable power, period.

From a Savannah perspective, our primary focus is on participating in Projects that Matter in Africa. We expect to continue to acquire hydrocarbon businesses and to reinvest the cash flows we generate in both hydrocarbon AND renewable energy projects. We firmly believe that Africa needs both if it is to be given the opportunity to grow and lift ever more of her citizens out of energy poverty.

Closing thoughts

I continue to be excited and optimistic about the future of our business and the urgency of enabling the African energy transition through responsible investment. We at Savannah are strongly positioned to take advantage of a significant shift in ownership of hydrocarbon assets, while participating in integrated power generation sources from both thermal and renewable energy sources to deliver electricity to millions of people who are not currently benefiting from a modern quality of life afforded by access to power. I believe that Savannah will achieve great things over the course of the coming years and look forward to continuing this journey with you, my fellow shareholders.

Lastly, I would like to extend thanks to all those who contributed to our successes in 2024 and beyond - my incredibly dedicated and passionate colleagues, our host governments, communities, local authorities and regulators, our shareholders and lenders, and our customers, suppliers and partners. Thank you all.

Chair's Statement

Dear fellow shareholders,

I am pleased to present Savannah's Annual Report for 2024. The year was marked by significant achievements and strategic advancements, particularly around our Nigerian assets and our portfolio of power projects.

Our commitment to safety and the well-being of our employees and contractors remains unwavering. We are particularly pleased to have maintained our achievement of a zero LTIR and zero TRIR in 2024, especially given the large compression project undertaken at our Uquo CPF in Nigeria.

In 2024, we achieved a significant reduction in our Scope 1 carbon emissions intensity to 5.7 kg CO₂e/boe (2023: 10.7 kg CO₂e/boe), which compares favourably to the average supermajors' Scope 1 and Scope 2 carbon intensity of 21.3 kg CO₂e/boe in 2024.26

We are grateful for the continued support and engagement of our stakeholders. As announced in 2024, the conversion of both the Uquo Field and Stubb Creek Field to new 20-year PMLs, effective December 2023, clearly highlights our collaborative efforts with host governments. During the year, we were honoured with visits from both Rt. Hon. Ekperikpe Ekpo, Nigeria's Minister of State, Petroleum Resources (Gas), and Chief Adebayo Adelabu, Nigeria's Minister of Power, to our Uquo CPF, while in Niger, we were delighted to host H.E. Professor Haoua Amadou, Niger's Minister of Energy, on a tour of our Parc Eolien de la Tarka wind farm project site. During the year, we also secured an agreement with the prestigious international financial institution, the DFC, to fund one-third of the pre-development costs of Parc Eolien de la Tarka. This brings the total pre-development funding secured for the project to approximately two-thirds, following a similar agreement reached with the IFC the prior year, and we expect to see further collaboration of this nature on future projects.

The strength of our presence and relationships with our customers in Nigeria was demonstrated by the successful securing and extension of three significant gas contracts in 2024, collectively amounting to a total of up to 105 MMscfpd, together with a further contract extension agreed post-year end. This highlights our critical role in Nigeria's energy sector, where we currently support c. 17% of the country's thermal power generation capacity. In addition, our social impact projects in our host countries continue to support a range of education, health, infrastructure and economic development initiatives, reinforcing our commitment to promoting socio-economic prosperity in line with Pillar 1 of our sustainability strategy.

The Board continues to use the 2018 Quoted Companies Alliance Corporate Governance Code as the basis of the Group's governance framework and the Corporate governance report on page 97 of the Annual Report explains how we applied these principles in 2024. It is vital to continue to develop our Board in line with the planned expansion of the Company, and Savannah places significant value on diversity of experience and expertise within our leadership team. 

I would like to extend my sincere thanks to Sir Stephen O'Brien and David Clarkson, who have recently retired from the Board after eight years of dedicated service. Their insight, integrity and presence around the Board table will be greatly missed, and I am pleased that both will continue to support Savannah in consultancy roles. I also look forward to welcoming Uyi Akpata and Kehinde Olamide Ogunwumiju to the Board in 2026. Both are highly respected professionals in finance and legal affairs respectively, with proven records supporting dynamic, high-growth organisations like Savannah. Their bios are provided on page 94 of the Annual Report.

We have endeavoured to keep in close contact with our shareholders during the recent periods of share suspension and I have been privileged to engage personally with a number of you in my role as Chair. The Board appreciates the patience of shareholders with the delay in publication of this Annual Report and the resulting share suspension. Please refer to Note 2 of the financial statements in the Annual Report for further information on the background to, and reasons for the delay and to the report of the Audit Committee on page 100 of the Annual Report which discusses the impact on the financial statements. The financial statements presented in the Annual Report are unchanged compared to the preliminary results announced on 6 June 2025.

Post-year end we successfully completed both the SIPEC Acquisition and the Uquo compression project, as well as announcing plans to acquire interests in three hydropower projects, marking our entry into five new African countries. I believe these significant achievements position us well for the remainder of 2025 and beyond, as we continue to grow the business and deliver for our stakeholders.

Finally, I thank you for your continued support.

Sincerely,

Joseph Pagop Noupoué

Chair of the Board

Financial Review

Financial performance ahead of market guidance

Performance Against Market Guidance 2024

Year in Summary

Our business in Nigeria continued to perform well during 2024, delivering gas to five customers such as power stations and other large industrial companies, and supporting approximately 17% of Nigeria's available thermal power generation.

Total Income(b) for the year was US$393.8 million (2023: US$289.8 million), comprising Total Revenues(a) of US$258.9 million (2023: US$260.9 million) and other operating income of US$134.9 million (2023: US$28.9 million), with a resulting Adjusted EBITDA(d) of US$181.2 million (2023 US$184.1 million).

Total Cash Collections(j) in 2024 were the highest we have received in any year at US$248.5 million (2023: US$206.0 million) and seeking a further increase in the rate of Cash Collections(j) in Nigeria remains a core focus in 2025.

Our Nigerian business is underpinned by long-dated, take-or-pay contracts which have no linkage to commodity pricing and provide long-term, predictable cash flows. At the end of 2024 we had over US$3.4 billion of future contracted revenues with an average weighted remaining contract life of 13 years.

We progressed major capital expenditure programmes during the year including completion of construction of the US$45 million Uquo gas compression project.

During 2024, Accugas fully utilised the NGN340 billion term facility (the "Transitional Facility") provided by a consortium of five Nigerian banks. The Transitional Facility has been used to pay down a substantial portion of the existing Accugas US$ Facility which at year end stood at US$212 million. This is the first step in the previously announced refinancing plan which will align the currency of Accugas' principal revenue Cash Collections(j) with its debt service obligations, significantly reducing Accugas' foreign exchange exposure.

Following a volatile year in 2023, we saw a significant devaluation in January 2024 of the Naira, which was followed by a comparatively stable environment for the rest of the year. This enabled Accugas to convert Naira cash balances and use proceeds of the Transitional Facility to pay interest and principal on the Accugas US$ Facility. The foreign exchange loss for the year amounted to US$78.1 million (2023: US$104.7 million) which was principally a result of the significant devaluation seen at the start of the year. Our customers pay for gas predominantly in Naira; however, under the terms of the GSA with our principal customer, the exchange losses realised can be invoiced via a true-up mechanism. The invoices raised under this provision are shown in our income statement as other operating income, referred to above.

Post-year end, in March 2025, we announced a £30.6 million equity raise with funds raised being used to repay/acquire subsidiary-level borrowings, accelerate business development opportunities and for general corporate purposes. We also announced a US$200 million acquisition debt facility to provide access to potential funding for future hydrocarbon asset acquisitions. In the same month we also announced the completion of the SIPEC Acquisition which was fully funded by a new debt facility arranged by The Standard Bank of South Africa Ltd. This transaction takes our economic interest in the oil producing Stubb Creek field to 100%. Post-year end, Stubb Creek average production (in September 2025) has increased by approximately 24% compared to 2024 average to 3.3 Kbopd.

As set out in the Audit Committee Report (and Note 2 of the financial statements) in the Annual Report, a number of internal financial control matters were identified during 2025. As a result of this, and as set out in the Independent auditor's report (and Note 2 of the financial statements) in the Annual Report, the audit opinion has been disclaimed in relation to these matters. A number of remedial actions have been identified and the Group is focused on implementing enhancements, which includes the establishment of an internal audit function during 2025.

Key Performance Metrics Summary

Consolidated Statement of Comprehensive Income

Revenue

Revenue during 2024 was US$227.0 million (2023: US$224.2 million), of which 88% was gas revenue US$199.8 million (2023: US$202.7 million) with US$26.4 million (2023: US$20.5 million) being derived from oil and condensate sales. US$0.8 million (2023: US$0.9 million) was for processing of third-party crude oil.

Gas is sold under a mixture of short and long-term gas sales agreements, all of which have individually agreed prices defined in US$, with certain long-term contracts adjusted annually for consumer price indexation. The majority of our gas sales contracts are supported by investment grade(f) guarantees, including a World Bank Partial Risk Guarantee for the Calabar power station gas sales contract.

The weighted average sales price for the year was up 4% to US$4.68/Mscfe (2023: US$4.51/Mscfe).

Impact of Take-or-pay Accounting Rules under IFRS 15 on Total Revenues(a) versus Revenue

Revenue recognition for our gas sales agreements is impacted by the take-or-pay accounting rules under IFRS 15. Under take-or-pay contracts, customers agree to buy a minimum amount of gas from us each year. This gas is either delivered to them, or the volume not taken (which is described as make-up gas) is effectively pre-paid for by the customer for potential delivery in future periods. During 2024, our customers took less gas than they had contracted to buy, so there was a difference between invoiced oil and gas sales of US$258.9 million (Total Revenues(a)) and revenue as reported in our consolidated statement of comprehensive income of US$227.0 million.

A key point to highlight is the cash neutrality of the take-or-pay accounting treatment; had our customers requested the make-up gas to be delivered to them in the accounting year, then all the invoiced sales would have been recognised as Revenue in the Consolidated statement of comprehensive income and our cash generation would have been the same in either case (as this reflects receipts from customers regardless of whether they related to delivered gas or make-up gas). We report Total Revenues(a) as management believes that this is a more meaningful method of describing the cash generation capacity of the business.

To provide further clarity on the take-or-pay accounting rules, please refer to the theoretical simplified worked example which is shown on page 57 of the 2020 Annual Report and Accounts, which can be accessed on our website.

Operating Expenses plus Administrative Expenses(g)

Operating expenses plus administrative expenses(g) for the year were US$71.0 million (2023: US$68.8 million) which compared favourably with guidance of up to US$75 million and the modest 3% increase reflects tight cost control in an inflationary environment, especially in Nigeria, and was lower than the increase seen in average sales price.

Depreciation, depletion and amortisation ("DD&A") amounted to US$35.7 million (2023: US$38.4 million) made up of US$13.9 million (2023: US$14.7 million) for infrastructure assets, which are depreciated on a straight-line basis over their estimated useful life, and US$18.0 million (2023: US$20.1 million) for upstream assets, which are depreciated on a unit-of-production basis, plus US$3.8 million (2023: US$3.6 million) for right-of-use and other assets.

Other Operating Income

Other operating income of US$135.2 million (2023: US$28.9 million) principally relates to amounts invoiced under the true-up mechanism in the GSA with our principal gas customer which allows for recovery of realised foreign exchange losses. Other operating income also includes an additional US$0.3 million (2023: zero) of grants received for renewable development projects.

Finance Costs

Finance costs for the year were stable at US$101.1 million (2023: US$102.7 million), of which US$97.9 million (2023: US$83.3 million) related to bank and loan note interest expense. The average interest rate on debt for the Group was 15.5% (2023: 14.1%), this increase being driven by the greater proportion of borrowings denominated in Naira.

Foreign Exchange Losses

Foreign exchange losses amounted to US$78.1 million (2023: US$104.7 million). The official Naira/US$ exchange rate devalued from around NGN900/US$ to NGN1,400/US$ in January 2024 and following such proactive action by the Central Bank of Nigeria we have seen more stable exchange rates for the remainder of the year, ending 2024 at NGN1,544/US$.

Consolidated Statement of Financial Position

Receivables and Payables

Trade receivables amounted to US$538.9 million (2023: US$389.9 million). The increase was largely due to the invoicing of foreign exchange losses incurred which were invoiced.

Trade and other payables reduced by over 25% in the year to US$80.1 million (2023: US$108.0 million) which will be settled in the normal course of business.

Debt

The net debt(h) at year end was US$636.9 million (2023: US$473.7 million), an increase of 34% year on year. The NGN340 billion Accugas Transitional Facility has now been fully drawn down and the resulting funds converted into US$ to partially repay the Accugas US$ Facility and to pay interest due. In September 2025, the Transitional Facility was extended so that the remainder of the Accugas US$ Facility can be repaid leaving all Accugas' borrowings in Naira, matching the currency in which it receives revenues for gas sales. The Transitional Facility has been increased post-year end to up to NGN772 billion.

Details of the debt facilities available to the Group are in Note 29 of the financial statements contained in the Annual Report. It is worth noting the treatment of the debt facility entered into to finance the acquisition of the Chad and Cameroon Assets. Despite the Nationalisation there remains an outstanding balance of US$134.6 million at the year end (2023: US$119.3 million). Of this amount only up to US$37 million is recourse to the Company.

Gross debt is US$669.5 million (2023: US$580.7 million) of which 94% is non-recourse to the Company.

Leverage(i)

Consolidated Statement of Cash Flows

Cash balances at year-end were US$32.6 million (2023: US$106.9 million). Cash balances reduced in the year despite the strong operational Cash Collections(j) performance due largely to unrealised foreign exchange loss resulting from Naira devaluation early in the year of US$57.4 million (2023: US$81.8 million). During the year, we also made debt repayments of US$148.7 million (2023: US$84.2 million) and reduced the interest due amount to US$27.2 million (2023: US$136.1 million). The debt repayments were also supported by drawdowns under the Transitional Facility.

We continued to invest in the asset base with capital expenditures of US$23.1 million (2023: US$13.0 million) related largely to the compression project at the Uquo CPF.

Going Concern

The Group places significant importance on managing its liquidity position and ensuring that all parts of the business have appropriate funding as needed to meet their obligations. The Directors have reviewed the Group's forecasted cash flows as well as the funding requirements of the Group for the period to 31 October 2026. This forecast was prepared on a "bottom-up" basis, at each major asset and corporate level, and it reflects the Group's best estimate of costs and revenues for the period. The capital expenditure and operating costs used in this forecast are based on the Group's approved corporate budget which includes operating budgets for each of the operating subsidiaries and an estimate of the corporate, general and administrative costs for the period.

The Directors recognise the range of risks facing the business on an ongoing basis, as set out in the Risk management section on page 86 of this Annual Report.

Notwithstanding the risks across the Group, both the base case forecasts and sensitised scenarios confirm that the Directors believe that the Group and each subsidiary company has sufficient liquidity to continue as a going concern for the period to 31 October 2026.

Please refer to Note 2 of the consolidated financial statements in the Annual Report for further details on the going concern review.

FY2025 Outlook

The key financial priorities for the remainder of 2025 include:

•   securing a further increase in our rate of Cash Collections(j) in Nigeria;

•   implementation of enhancements to the financial control environment in our Nigerian operations, including the establishment of a Group internal audit function;

•   with the increased Transitional Facility now in place, completion of the refinancing of our principal Nigerian debt facilities.
