关于辛塔纳集团
：辛塔纳集团在多个司法管辖区和盆地拥有高影响力资产的直接和间接权益。具体而言，这包括在纳米比亚和乌拉圭两国持有的八个许可证权益，以及在安哥拉一项许可证的待定间接权益（以及在哥伦比亚和巴哈马的遗留资产），从而使其能够多元化地接触到各种地质构造、盆地、运营商、监管机构、司法管辖区和地缘政治体系。该投资组合的核心是间接持有莫帕内（位于纳米比亚奥兰治盆地，石油勘探许可证“EL”83）的重大发现权益，以及其他多个资产中具有高影响力的勘探催化剂。

董事会认为，辛塔纳集团的投资组合具有以下特点：

多元化投资组合
——在纳米比亚和乌拉圭两个国家拥有八个许可证的权益，以及在安哥拉一个待定许可证的权益（以及在哥伦比亚和巴哈马的遗留资产），从而实现了对各种地质构造、盆地、运营商、监管机构、司法管辖区和地缘政治体系的多元化投资。该投资组合的核心是莫帕内（纳米比亚奥兰治盆地 PEL 83）重大发现的权益。以及其他多个资产中具有高影响力的勘探催化剂。

把握近期高价值活动机遇
——辛塔纳集团的投资组合目前专注于纳米比亚和乌拉圭——这两个地区都被视为全球勘探热点——预计未来24个月内，包括地震勘探和钻井在内的重要勘探活动将持续进行。

已建立的合作伙伴关系
——在纳米比亚，辛塔纳集团持有多个许可证权益，并与包括雪佛龙、Galp、Pancontinental和NAMCOR在内的知名运营商建立了合作伙伴关系。在乌拉圭，辛塔纳集团与雪佛龙合作开发AREA OFF-1区块；在安哥拉，辛塔纳集团将与Corcel plc合作开发KON-16区块（前提是完成对该区块权益的收购交易）。

通过权益承销降低资本风险
——辛塔纳集团的战略是构建并维护一个主要由经验丰富的国际运营商负责勘探、评估和开发的权益组合，从而使辛塔纳集团的股东能够参与到辛塔纳所需资本相对有限的项目和前景中。目前，辛塔纳集团在纳米比亚的五个海上许可证权益中的四个（包括已发现莫帕内油田的PEL 83区块）以及乌拉圭的AREA OFF-1区块均享有全部或部分权益承销权。

执行能力
——辛塔纳集团认为其拥有强大的技术和商业能力，能够有效管理其权益组合并最终创造丰厚回报。尤其值得一提的是，辛塔纳的董事会和管理团队拥有深厚的行业经验和专业知识。

规模和融资效率
——Sintana上市时的市值预计约为1.28亿英镑，使其成为“小市值”勘探领域中规模庞大、差异化竞争的参与者。公司拥有关键许可证的丰厚收益支持、超过1000万美元的现金和流动资金，并具备更强的融资能力，可根据需要或机遇充分利用现有资产组合，并实现业务的战略性增长。潜在

的实现机会
——Sintana集团的资产组合涵盖极具前景的勘探项目，其中Mopane项目更是规模可观的发现。由此，通过资产变现（包括出售或剥离关键资产）实现从勘探到发现的多重价值提升，将显著提升股东回报的机会。资产

组合概览：
Sintana集团的资产组合目前包括：

- 在纳米比亚近海奥兰治盆地的四个大型、极具前景的勘探区块中拥有间接权益，包括对 PEL 83 的间接权益，该区块是 2023 年和 2024 年发现的莫帕内油田所在地，以及对 PEL 79、87 和 90 的间接权益；
- 在纳米比亚近海沃尔维斯盆地的一个勘探区块（PEL 82）和纳米比亚陆上沃特伯格盆地的一个勘探区块（PEL 103）中拥有间接权益；
- 在乌拉圭的两个海上区块的直接权益，分别是埃斯特角城盆地的 AREA OFF-1 和佩洛塔斯盆地的 AREA OFF-3（这些权益在 2025 年 12 月 16 日完成对 Challenger Group 的收购后，成为 Sintana 集团投资组合的一部分（“收购”））；-
在安哥拉陆上宽扎盆地的 KON-16 许可证的间接权益（取决于 Sintana 于 2025 年 5 月签订的收购该权益的交易完成情况，预计将于 2026 年上半年完成）；以及
- 在哥伦比亚中部马格达莱纳盆地和巴哈马近海的陆上遗留资产。

融资协议
为配合本次收购的完成，Sintana 与 Sintana 和 Challenger 的股东 Charlestown Energy Partners, LLC（“Charlestown”）于 2025 年 10 月 9 日签订了一份融资协议（“贷款协议”）。根据该协议，Charlestown 同意向 Sintana 提供最高 400 万美元的营运资金融资（“融资额度”）。该融资额度为无担保融资，有效期自 2025 年 10 月 9 日至 2028 年 6 月 30 日。

截至本协议签署之日，该融资额度尚未提取，其用途仅限于作为“备用”资金来源，以便在 Sintana 需要时为其提供额外的营运资金支持。 Sintana可自行决定是否提取贷款，且Sintana可随时终止贷款协议，但须至少提前20个工作日以书面形式通知Charlestown。如Sintana选择提取贷款，每次提取金额不得少于25万美元，利息按纽约联邦储备银行公布的担保隔夜融资利率上浮5%计算。违约利息另加2%。Charlestown

可在发生典型违约事件时加速和/或终止贷款。Charlestown亦可选择将Sintana的任何负债与Charlestown对Sintana的任何负债进行抵销，无论该负债是否源于贷款协议、款项到期日是否不同，或款项以何种货币计价。

作为提供该项融资的对价，Charlestown 将获得 80,000 美元的安排费，该费用应于 2028 年 6 月 30 日或根据贷款协议条款终止之日（以较早者为准）支付；此外，Charlestown 还将获得每年 80,000 美元的可用性费用，该费用按日累积，并应于 2028 年 6 月 30 日或根据贷款协议条款终止之日（以较早者为准）支付。根据贷款协议条款，Charlestown 无需支付任何奖金、股权发行或其他非现金对价。

由于 Sintana 首席执行官 Robert Bose 是 Sintana 的首席执行官兼董事，同时也是 Charlestown 的负责人，因此该贷款协议构成《多边文书 61-101——特殊交易中少数股东权益的保护》（简称“I 61-101”）项下的“关联方交易”。截至上市之日，Bose先生和Charlestown合计（直接和间接）持有Sintana公司27,578,415股普通股（约占Sintana公司所有已发行及流通普通股的5.4%）。除以下事实外：(i) Charlestown公司因与Sintana公司共用一位董事，构成TSXV政策手册（“TSXV政策”）中定义的非关联方，符合TSXV政策1.1的规定；(ii) 该项融资须遵守TSXV政策5.1的披露要求，该项贷款协议不构成TSXV政策所规定的非关联方交易。

尽管该贷款协议属于“关联方交易”（定义见 MI 61-101），但根据第 5.7(1)(f) 条的豁免规定，该贷款协议无需按照 MI 61-101 进行正式估值和获得少数股东批准，因为该贷款协议的条款是合理的商业条款，对 Sintana 的有利程度不低于从与 Sintana 进行公平交易的人处获得该贷款，并且该贷款不能直接或间接地转换为 Sintana 或其任何子公司的股权或有表决权证券，也不能偿还（本金或利息）。



多伦多创业 交易所 (TSXV) 已就贷款协议出具无异议函，最终批准仍需以本新闻稿的提交和发布为准。Sintana
还宣布，为配合此次收购，公司已向以下董事及高管（“受让人”）发行总计 2,512,943 股普通股（“离职补偿股份”），每股作价 0.52 加元，以代替因收购而失去职务或董事职位而应支付的全部或部分离职补偿金，总额为 1,417,030 加元。

姓名 普通股 遣散费金额（加元）
Keith Spickelmier 327,500 280,600
Doug Manner 620,558 322,690
Eytan Uliel 1,564,885 813,750

该等遣散股份系根据加拿大证券法适用的招股说明书豁免条款发行，且不属于公司股权激励计划的范畴，作为一次性激励和/或遣散费，并按照TSXV政策4.4第6.4节“基于证券的补偿”的条款支付。根据TSXV和加拿大证券法的政策，该等遣散股份自发行之日起须持有四个月零一天，至2026年4月24日到期。

除乌利尔先生外，其他每位接收人均因其曾担任辛塔纳公司执行主席（基思·斯皮克尔迈尔）和董事（道格·曼纳）而构成MI 61-101所定义的“关联方”，因此，此次离职补偿股份的发行构成MI 61-101所定义的“关联方交易”。尽管构成MI 61-101所定义的“关联方交易”，但根据MI 61-101第5.5(b)条和第5.7(1)(a)条的豁免规定，此次离职补偿股份的发行无需进行正式估值和少数股东批准，因为就涉及利益相关方而言，离职补偿股份的公允市场价值（及其对价）不超过公司市值的25%。

根据多伦多创业交易所（TSXV）的政策，此次离职补偿股份的发行不属于非关联方交易。TSXV

已附条件批准此次离职补偿股份的发行。最终批准仍需待本新闻稿的提交和发布后方可生效。

总投票权
完成上市及根据收购协议对零碎股份进行四舍五入后，公司已发行及流通在外的股本将由510,356,240股普通股组成，每股均享有投票权。公司股东可使用该股本作为分母，根据英国金融行为监管局（FCA）的披露指引和透明度规则，计算其是否需要就其在公司股本中的权益或权益变更进行申报。公司不持有任何库存股。

Sintana Energy Inc. (“Sintana” or the “Company”) is pleased to announce the admission of its common shares represented by depositary interests ("Common Shares") to trading on the AIM market of the London Stock Exchange plc ("AIM") ("Admission").

Dealings commenced at 8:00amGMT on Tuesday 23 December 2025, under the ticker "SEI" (ISIN: CA82938H1073) and with an expected market capitalization of circa. £128 million.

The Admission Document was published on 18 December 2025 and is available to view on the Company’s website at: https://sintanaenergy.com/

The Common Shares will continue to be listed and traded on the TSX Venture Exchange (“TSXV”) in Canada under the symbol “SEI”, and on the OTCQX market in the United States of America under the symbol “SEUSF”.

Robert Bose, CEO of Sintana, stated: “Today's admission to the AIM market of the London Stock Exchange is not only the culmination of our transformational acquisition of Challenger Energy Group and our related commitment to provide local liquidity to AIM based shareholders, but also the setting of a new foundation for the combined group. With listings and high-impact exploration interests on both sides of the Atlantic, the enlarged Sintana is positioned to attract and deliver for a wider range of shareholders going forward. Many thanks to all who were involved in assistance and guiding us to this key milestone.”

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 £128 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.

Facility Agreement
In connection with the closing of the Acquisition, Sintana and Charlestown Energy Partners, LLC ("Charlestown"), a shareholder in Sintana and Challenger, entered into a facility agreement dated 9 October 2025 (the "Loan Agreement") pursuant to which Charlestown has agreed to provide Sintana with a working capital facility of up to US$4 million (the “Facility”). The Facility is unsecured and available from 9 October 2025 until 30 June 2028.

As at the date hereof, the Facility has not been drawn and is intended to operate solely as a “stand-by” source of funding, affording access to additional capital to support working capital needs as and when it may be required by Sintana. Drawdowns are solely at the election of Sintana, and the Loan Agreement can be terminated by Sintana at any time by giving not less than 20 business days’ prior written notice to Charlestown. Should Sintana elect to draw on the Facility, each drawdown must be a minimum of US$250,000, and interest accrues at a rate of 5% above the secured overnight financing rate published by the Federal Reserve Bank of New York. Default interest accrues at an additional 2%.

Charlestown may accelerate and/or cancel the Facility upon typical events of default. Charlestown may also elect to set off any liability of Sintana against any liability of Charlestown to Sintana regardless of whether the liability arises under the Loan Agreement, the amounts are due at different times, or the amounts are in different currencies.

As consideration for providing the Facility, Charlestown will be paid an arrangement fee of US$80,000, payable on the earlier of 30 June 2028 or the date that the Loan Agreement is terminated in accordance with its terms, as well as an availability fee of US$80,000 per annum, accruing daily and payable on the earlier of 30 June 2028 or the date that the Loan Agreement is terminated in accordance with its terms. No bonus, equity issuance, or other non-cash considerations are payable under the terms of the Loan Agreement.

The Loan Agreement constitutes a “related party transaction” under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101”) as Robert Bose, Sintana's Chief Executive Officer, is a related party by virtue of being the CEO and director of Sintana, and a principal of Charlestown. Together, Mr. Bose and Charlestown hold (directly and indirectly) an aggregate of 27,578,415 common shares in the capital of Sintana as at Admission (representing approximately 5.4% of all issued and outstanding common shares of Sintana). Other than the facts that (i) Charlestown is a Non-Arm’s Length Party (as defined in the TSXV policy manual ("TSXV Policies")) for the purposes of TSXV Policy 1.1 (as a result of sharing a common director with Sintana), and (ii) the Facility is subject to TSXV Policy 5.1 disclosures, the Loan Agreement does not constitute a Non-Arm’s Length Party transaction (as defined in TSXV Policies) under the categories contemplated in TSXV Policies.

Despite being a "related party transaction" (as defined in MI 61-101), the Loan Agreement is exempt from formal valuation and minority shareholder approval under MI?61-101 by the application of the exemption under Section 5.7(1)(f), as the Loan Agreement is on reasonable commercial terms that are not less advantageous to Sintana than if the Facility were obtained from a person dealing at arm’s length with Sintana, and the Facility is not convertible or repayable (in principal or interest), directly or indirectly, into equity or voting securities of Sintana nor any of its subsidiaries.

The TSXV has provided a non-objection letter with respect to the Loan Agreement, and final approval remains subject to the filing and dissemination of this comprehensive news release.

Shares for Severance
Sintana also announces that in connection with the Acquisition, it has issued an aggregate of 2,512,943 common shares in the capital of the Company (the "Severance Shares") at a deemed issue price of CDN$0.52 to the below directors and officers of the Company (the "Recipients") in lieu of all or part of severance payments totalling CDN$1,417,030 owing to same as a result of their loss of office or directorship in connection with the Acquisition.

Name Common Shares Severance Amount (CDN$)
Keith Spickelmier 327,500 280,600
Doug Manner 620,558 322,690
Eytan Uliel 1,564,885 813,750

The Severance Shares were issued pursuant to applicable prospectus exemptions under Canadian securities laws, and outside of the Company's equity incentive plan as a one-time inducement and/or severance payment paid in accordance with the terms of Section 6.4 of TSXV Policy 4.4. – Security Based Compensation. The Severance Shares are subject to a hold period of four months and one day from the date of issuance, expiring on 24 April 2026, pursuant to the policies of the TSXV and Canadian securities laws.

Since each Recipient other than Mr. Uliel is a "related party" of the Company within the meaning of MI 61-101 by virtue of their previous roles as executive chairman (Keith Spickelmier) and director (Doug Manner) of Sintana, the issuance of the Severance Shares constitutes a "related party transaction" (as defined in MI 61-101). Despite being a "related party transaction" (as defined in MI 61-101), the issuance of the Severance Shares is exempt from formal valuation and minority shareholder approval under MI?61-101 by the application of the exemptions under Sections 5.5(b) and 5.7(1)(a) of MI 61-101 as the fair market value of the Severance Shares (and the consideration therefor), insofar as it involves interested parties, does not exceed 25% of the Company’s market capitalisation.

The issuance of the Severance Shares is not a Non-Arm's Length Party Transaction under the policies of the TSXV.

The TSXV has conditionally approved the issuance of the Severance Shares. Final approval remains subject to the filing and dissemination of this comprehensive news release.

Total Voting Rights
Following Admission and the rounding of fractional entitlements pursuant to the Acquisition, the Company's issued and outstanding share capital will comprise of 510,356,240 Common Shares each with voting rights, and this number may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change in their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules. The Company does not hold any shares in treasury.
