CHAIRMAN AND CHIEF EXECUTIVE OFFICER’S STATEMENT FOR THE SIX MONTHS ENDED 30 JUNE 2026

Dear Shareholder,

I’m pleased to share our interim results for the period to 30 June, 2026, and also to share an update regarding our farm-out approvals and our operating plans over the months ahead.

In summary, as previously announced, in Namibia we already received the letter from the Minister of Industries, Mines and Energy (“MIME”) approving the farm-out of a 25% interest in PEL 96 to Prime Global Energies Limited (“Prime”) at the end of June 2026, and although it took a while to get the wet signatures of all parties on the deed of assignment, this is now only awaiting the Minister’s signature which is expected any day.

In Cameroon, the President’s authorisation for the further extension of the initial exploration period of our Thali license, and for the farm-out to Prime, has been granted and has been making its way down through the usual channels from the Office of the President and the Prime Minister’s Office to the Minister of Mines, Industry and Technological Development (“MINMIDT”) and to the Societé Nationale des Hydrocarbures (“SNH”). We have now seen a copy of the letter from the President’s office to the Prime Minister’s office and to MINMIDT and SNH confirming the President’s authorisation and instructions. MINMIDT has advised us that they are now preparing the formal “arrêté” confirming the extension and the formal letter of approval for the farm-out to Prime, which we expect to receive shortly.

Cameroon

We have continued to maintain drilling readiness, and since the beginning of the year we took delivery of the mud-line suspension system which allows us to suspend the NJOM-3 well after testing so that we are able to re-enter it as a production well in due course. This equipment is now at our storage facility in Douala along with the other long lead items for the NJOM-3 well.

We also continue to monitor the rigs available for drilling the NJOM-3 well, and we currently expect to be spudding the well early in the second quarter of 2027. While it may still be possible to spud in the first quarter, we think it is best to set expectations for second quarter at this stage. We do not intend to discuss rig selection or timing any further until we have made a final rig selection that is contractually confirmed, in order to preserve the confidentiality of those commercial discussions.

Draft service agreements are already in place for all services, but we will review and finalise these (and will have time to do so) when the rig selection and timing are known.

We have also continued discussions on the financing of the next phase of work on the Njonji structure, conditional on the NJOM-3 well results, in order to minimise the elapsed time between the NJOM-3 well and the drilling of the subsequent production wells.

Namibia

In Namibia, we have already scheduled the next PEL96 Operating Committee meeting together with Prime as well as NAMCOR and our local partners for early October, to discuss the next stage of our work programme.

As shareholders may recall, we completed an extensive basin modelling exercise as part of our initial work programme on PEL96. We have subsequently reviewed all of our existing 2D seismic data over our acreage, which has led us to identify a number of interesting stratigraphic leads of similar architecture to the major discoveries which have made to the South in the Orange Basin. Significantly, these are located along the expected oil migration paths we have also identified. These stratigraphic leads are in addition to the four-way dip closures that we had already identified in the license area, and these are also consistent with the oil seep data that we have studied. Our next step is therefore to acquire additional seismic data in order to narrow down further the most interesting leads and the area within the license where we would like to acquire new 3D seismic data.

There is a possibility to acquire additional seismic data directly in the first half of 2027, when the weather window is suitable, but the economics of doing this will depend critically, among other things, on whether our neighbours are also ready to acquire data. However, we are also exploring other alternative sources of data in case this is not a viable option.

South Africa

In South Africa, as we disclosed in our annual report in June 2026, we made the decision to impair the carrying value of our 50% interest in the Algoa-Gamtoos license due to the continuing uncertainty in the legislative environment which is still limiting seismic data acquisition and other activity in the offshore basins. At the same time, the discussions that the Operator of the license had been conducting with a potential farm-in partner appear to have stalled. As we explained in June, we intend to continue working in South Africa, albeit at a modest pace, while we wait to see if things begin to move forward again.

Corporate

We have been forced to raise a significant amount of equity financing during the first eight months of this year, part of which was to repay loans taken in lieu of equity financing in 2025, and this has been an unfortunate consequence of the delay in receiving government approvals, which I discussed at length in our annual report a few months ago. However, we do believe that with our approvals in hand, we will not be needing further equity financing this year for existing commitments.

One can never say never: we are a public company precisely so that we can raise funds, not merely to meet immediate cash needs but also to finance further opportunities, and this is a good environment for opportunities. We are looking at a range of open licenses in West Africa and Southern Africa, and we are struck by the enthusiasm and realism governments are now showing in seeking to bring new independent oil company investment into both exploration and also the development of existing discoveries. But we are also very aware that shareholders have had to fund the delays of the last eighteen months, and I can only say that I believe this investment will be rewarded in the months and years ahead.

INTERIM CONSOLIDATED STATEMENT OF CHANGES IN EQUITY

1 The share-based payment reserve has been included within the retained loss reserve and is a non-distributable reserve.

INTERIM CONSOLIDATED STATEMENT OF CASH FLOWS

NOTES TO THE INTERIM FINANCIAL INFORMATION

1. Accounting policies

1.                Basis of preparation

This interim financial report, which includes a condensed set of financial statements of the Company and its subsidiary undertakings (“the Group”), has been prepared using the historical cost convention and based on International Financial Reporting Standards (“IFRS”) including IAS 34 ‘Interim Financial Reporting’ and IFRS 6 ‘Exploration for and Evaluation of Mineral Reserves’, as adopted by the United Kingdom (“UK”).

The condensed set of financial statements for the six months ended 30 June 2026 is unaudited and does not constitute statutory accounts as defined in Section 434 of the Companies Act 2006. They have been prepared using accounting bases and policies consistent with those used in the preparation of the audited financial statements of the Company and the Group for the year ended 31 December 2025 and those to be used for the year ending 31 December 2026. The comparative figures for the half year ended 30 June 2025 are unaudited. The comparative figures for the year ended 31 December 2025 are not the Company’s full statutory accounts but have been extracted from the audited financial which have been delivered to the Registrar of Companies. The auditors’ report thereon was unqualified and did not contain a statement under sections 498(2) and 498(3) of the Companies Act 2006.

This half-yearly financial report was approved by the Board of Directors on 28 September 2026.

2.               Going concern

The Group will need to complete the agreed Cameroon farm-out with Prime Global Energies Limited and/or another asset-level transaction, or raise additional funds beyond those raised in 2026, to meet its liabilities as they fall due, including the costs associated with the forthcoming drilling programme in Cameroon. While the Directors are confident that the agreed farm-out will be completed, there can be no certainty that this will occur within the required timeframe.

The Cameroon farm-out with Prime Global Energies Limited should cover the balance of the financing required for the company’s upcoming appraisal well in Cameroon, but testing and further development to production will require significant additional investment and funding in due course.

Similarly, the Group’s assets in Namibia and South Africa are also pre-revenue and will require further funding to support their development.

The Directors believe that there are a number of options available to fund these investments through any, or a combination, of production pre-financing, reserve-based lending, capital markets, further farm-outs or asset disposals. There can, however, be no guarantee that the required funds may be raised or transactions completed within the necessary timeframes, which results in an inherent material uncertainty as to the application of going concern in these accounts. Having assessed the risks attached to these uncertainties on a probabilistic basis, the Directors are confident that they can raise sufficient finance in a timely manner and therefore believe that the application of going concern is both appropriate and correct.

2. Operating segments

The Group has two reportable operating segments: Africa and Head Office. Non-current assets and operating liabilities are located in Africa, whilst the majority of current assets are carried at Head Office. The Group has not yet commenced production and therefore has no revenue. Each reportable segment adopts the same accounting policies. In compliance with IAS 34 ‘Interim Financial Reporting’ the following table reconciles the operational loss and the assets and liabilities of each reportable segment with the consolidated figures presented in these Financial Statements, together with comparative figures for the period-ended 30 June 2025.

3. Loss per ordinary share

Prime Global Energies Limited

On 10 January 2025, the Group entered into a farm-out agreement with Prime Global Energies Limited (“Prime”) in relation to minority, non-operated interests in the Thali licence offshore Cameroon and PEL96 offshore Namibia.

Through Tower Resources Cameroon S.A., the Group agreed to farm out a 42.5% non-operated interest in the Thali licence to Prime, as part of which Prime agreed to make a $15.0 million cash investment in the Thali work programme, including the drilling of the NJOM-3 well. In addition, through Tower Resources (Namibia) Limited, Prime has agreed to farm into PEL96 offshore Namibia for a 25% non-operated interest.

In connection with these farm-outs and related transactions, including amendments to existing arrangements and the issue of new shares to Pegasus Petroleum Limited, a significant shareholder of the Company, Tower has received $938k in cash and is due to receive a further $3.4 million upon completion of the two farm-outs and related transactions, representing total cash consideration of approximately $4.4 million.

Completion of the farm-outs remains subject to the receipt of fully executed documents in both Cameroon and Namibia. The Directors expect that completion of both farm-outs will occur in due course, although the timing of completion remains uncertain.

Cameroon

Capitalised expenditure of $453k was incurred during the period to 30 June 2026 (2025: $982k). This expenditure primarily comprised ongoing costs associated with preparation for the NJOM-3 appraisal well, including engineering and drilling planning activities, together with the capitalised costs of operating the Group’s local office in Douala.

The Directors have not recognised any impairment in respect of the Group’s investment in the Thali licence. This assessment principally reflects the farm-out agreement with Prime, as described above, together with the Group’s internal cash flow projections, both of which support the Directors’ conclusion that the current carrying value of the licence is recoverable in full.

Tower Resources Cameroon S.A., the Group’s operating subsidiary, has applied for, and is expected to receive, a further extension to the First Exploration Period of the licence. This extension is expected to be granted concurrently with Government of Cameroon approval of the farm-out to Prime.

Namibia

The Group continued to make licence commitment and training payments under PEL96 to the Government of the Republic of Namibia in accordance with its work programme commitments. The Group has also now received all partner consents required for Prime’s farm-in. A number of Government departments have similarly provided their consent, with the transaction now awaiting final ministerial execution.

The Company’s investment in the licence currently stands at $1.6 million (2025: $1.4 million). This carrying value is supported by valuations implied by recent transactions in the region, taking into account the early stage of the licence’s evaluation and appraisal programme and the implied value of the farm-out to Prime, as described above.

The Directors also continue to consider that the relatively modest expenditure incurred to acquire and maintain the licence is supported by their initial assessment of its prospectivity, based on the information currently available.

The Minister of Mines, Industries and Energy approved the entry into the First Renewal Period of the PEL96 in June 2025.

South Africa

In South Africa, Rift Petroleum Limited, Tower’s wholly owned subsidiary, and its JV partner and operator New African Global Energy SA (Pty) Ltd, have yet to conclude upon a timeline to tender for, acquire and evaluate the 3D seismic data and no firm budget to do so has been agreed.  The second renewal period commits the JV to the acquisition of 700km of 2D seismic acquisition or the acquisition of 300km of 3D seismic. The minimum spend is $5.0 million in total to the JV and this period will conclude upon the completion of the work programme, representing a commitment to acquire a minimum of 700km 2D or 300km of 3D seismic over the block. Acquiring the additional seismic data before 2028 is now unlikely, given the recent uncertainty and litigation over environmental regulations. The operator has told the Company that PASA accepts this position and merely requires that the seismic acquisition obligation is completed before the JV enters the next renewal period.

Impairment

In accordance with the Group’s accounting policies and IFRS 6, Exploration for and Evaluation of Mineral Resources, the Directors have reviewed each of the Group’s Cash Generating Units (“CGUs”) represented by its licence areas for indicators of impairment.

Following this review, the Directors concluded that a full impairment assessment was not required in respect of either the Cameroon or Namibian CGUs.

In South Africa, during its review of the 2025 full year accounts in May 2026, the Directors concluded that, given that substantive expenditure on further exploration and evaluation of mineral resources on the Algoa-Gamtoos licence is neither budgeted nor planned in the short term as a result of the prevailing regulatory uncertainty, a full impairment provision in respect of all capitalised amounts was appropriate under IAS 36. Accordingly, the capitalised amounts relating to the licence have been fully impaired.

7. Trade and other receivables

Trade and other receivables comprise amounts due from other parties and prepayments arising in the ordinary course of business.

8. Trade and other payables

Other payables include amounts payable to Pegasus Petroleum in respect of existing production-based payment arrangements relating to the Thali licence, which Pegasus has agreed to amend in favour of Prime and Tower.

Accruals include amounts of $569k in the UK (2025: $606k), $532k in Cameroon (2025: $532k) and $398k in Namibia (2025: $252k). These amounts include bonuses of $638k (2025: $638k) contingent upon completion of the Prime transaction, together with $813k (2025: $751k) relating to operational and other asset-related costs payable, as well as amounts due to ministerial bodies in respect of licence tenure.

Trade payables comprise short-term, unsecured obligations incurred in the ordinary course of business. The Group's creditor payment period is approximately 30 days (2025: 30 days).

9. Borrowings

Borrowings at the year-end included a £50k Barclays Bounce Back Loan, which was drawn down in May 2020 and the final repayment was made in May 2026.

On 25 March 2025, the Company entered into a fixed-price convertible loan of £500k with Prime Resources for a period of 12 months. The principal terms of the loan included a 5% cash implementation fee and interest at a rate of 15% per annum, or pro-rata for any shorter period, accruing daily and payable on maturity. The loan was subsequently expanded to a total of £1 million.

The loan was repaid in full, with accrued interest, at the end of March 2026.
