Information on Sintana
The Sintana Group holds a portfolio of direct and indirect interests in high-impact assets in multiple jurisdictions and basins. Specifically, this includes interests in eight licences in two countries, Namibia and Uruguay, as well as a pending indirect interest in a licence in Angola (and legacy assets in Colombia and The Bahamas), thus providing diversified exposure to a range of geologic plays, basins, operators, regulators, jurisdictions and geopolitical regimes. The portfolio is anchored by an indirect interest in the significant discoveries at Mopane (contained in petroleum exploration licence ("PEL") 83 in the Orange Basin, Namibia), together with additional high-impact exploration catalysts across multiple other assets.
The Board believes that the Sintana Group's portfolio of interests has the following attributes:
A diversified portfolio
· Interests in eight licences in two countries, Namibia and Uruguay, as well as a pending interest in a licence in Angola (and legacy assets in Colombia and The Bahamas), thus providing diversified exposure to a range of geologic plays, basins, operators, regulators, jurisdictions and geopolitical regimes. The portfolio is anchored by an interest in the significant discoveries at Mopane (PEL 83, Orange Basin, Namibia), together with additional high-impact exploration catalysts across multiple other assets.
Exposure to near-term high value activity
· The Sintana Group's portfolio is currently focussed on Namibia and Uruguay - both jurisdictions considered to be global exploration "hot spots", where significant exploration activity, including seismic campaigns and well drilling, is expected to continue over the next 24 months.
Established partnerships in place
· In Namibia, the Sintana Group holds interests in licences benefitting from established partnerships with well-regarded operators including Chevron, Galp, Pancontinental and NAMCOR. In Uruguay, the Sintana Group is partnered with Chevron on the AREA OFF-1 block and in Angola, the Sintana Group will be partnered with Corcel plc on the KON-16 block (subject to completion of the transaction to acquire an interest in that block).
Reduced capital exposure through carries
· The Sintana Group's strategy is to create and maintain a portfolio of its interests that are predominantly carried through exploration, appraisal and development by experienced, international operators, thereby providing the Sintana Group's shareholders with exposure to projects and prospects where comparatively limited capital is required from Sintana. Currently, the Sintana Group benefits from full or partial carried interest positions in relation to four of its five offshore licence interests in Namibia (including on PEL 83 where the Mopane discoveries have been made), as well as on AREA OFF-1 in Uruguay.
Execution capability
· The Sintana Group considers that it has strong technical and commercial capabilities that can be brought to bear on managing its portfolio and ultimately creating significant returns. In particular, Sintana has a board and management team with deep sector experience and expertise.
Scale and funding efficiency
· Sintana's market capitalisation on Admission is expected to be approximately £107 million, offering a scaled, differentiated player in the "small-cap" exploration space, with significant carry support on key licences, cash and liquid resources in excess of US$10 million, and an improved capacity to access funding as and when required or opportune to fully exploit its existing portfolio and strategically grow its business.
Potential realisation opportunities
· The Sintana Group's portfolio provides exposure to highly prospective exploration prospects and, in the case of Mopane, discoveries of significant scale. The resulting ability to potentially realise multiple value uplifts from prospect to discovery via monetisation (including sale or divestment of key assets) significantly enhances the opportunities for shareholder returns.
Summary Portfolio
Sintana Group's portfolio currently comprises of:
· indirect interests in four large, highly prospective PELs in the Orange Basin, offshore Namibia, including an indirect carried interest in PEL 83, home of the Mopane discoveries that were made in 2023 and 2024, as well as indirect interests in PELs 79, 87 and 90;
· an indirect interest in one PEL offshore Namibia in the Walvis Basin (PEL 82), and one PEL onshore Namibia in the Waterberg Basin (PEL 103);
· direct interests in two offshore blocks in Uruguay, being AREA OFF-1 in the Punta del Este Basin and AREA OFF-3 in the Pelotas Basin (these interests having become part of the Sintana Group's portfolio on completion of the acquisition of the Challenger Group on 16 December 2025 (the "Acquisition"));
· an indirect interest in the KON-16 licence in the onshore Kwanza Basin in Angola (subject to completion of the transaction to acquire that interest, which was entered into by Sintana in May 2025, with completion expected in H1 2026); and
· legacy assets onshore in the Middle Magdalena Basin, Colombia, and offshore The Bahamas.

Uruguay Update
On 10 December 2025, the Uruguayan Ministry of Environment issued permits to four seismic vendors to enable seismic acquisition in the territorial waters of Uruguay, following an extensive consultation and permitting process. On 17 December 2025, the Company received notification of a legal action that has been initiated by two local Uruguayan environmental groups, seeking to enjoin all licencees of the Uruguayan offshore O&G industry from conducting any work relating to their licenses, including seismic acquisition, as a preliminary measure to a determination as to the validity of licences issued by the Uruguayan State. The legal action has named ANCAP (the Uruguayan regulator and national oil company), every industry participant in Uruguay (including the Company and Chevron) and the four approved seismic vendors as respondents. The judge declined to consider the injunction request on an ex parte basis, and has instead ordered the industry to submit responses, which are due on 26 December 2025. The Group considers the proceedings to be without merit, and is working alongside ANCAP, Chevron and other industry participants to respond accordingly. Thereafter, the judge will determine the appropriate course for further hearings (if any) and ultimate resolution of the matter - further updates will be provided as appropriate.
