• Shareholders of Challenger will receive Sintana shares, giving them a stake in the combined entity’s future growth.
• New leadership from Challenger will join Sintana, blending expertise for future projects.

Let’s dive into the details of this exciting development.

Why did Sintana Energy acquire Challenger Energy Group, and what’s the strategic goal?

Sintana Energy’s goal with the Challenger Energy acquisition is to become a leading force in high-impact hydrocarbon exploration, particularly across the promising Southern Atlantic margin. Robert Bose, Sintana’s CEO, put it best: this combination “delivers on our long-term strategy to create and execute on a portfolio of exposures to high impact exploration opportunities.” Essentially, Sintana wants to broaden its reach and tap into the huge potential from Namibia and Angola all the way to Uruguay.

The combined company will have more exciting exploration projects on its plate, backed by partnerships with major industry players. Think about it: they’ll have eight licenses spread across Namibia and Uruguay (plus some older assets in The Bahamas and Colombia). This means they’re exposed to different geological areas, operating partners, regulatory bodies, and even political landscapes. This variety helps spread the risk. On top of that, they’re bringing together a top-notch Board and management team with tons of industry experience, giving them a real edge. A bigger, more diverse company also means:

• Strong financial backing for key licenses.
• Over US$10 million in immediate cash.
• Better access to funding to chase ambitious growth plans and develop existing projects.

This strategic move is all about building a more resilient and growth-oriented energy company. If you’re curious about different energy sources, you can learn more about the composition of natural gas.

What are Challenger Energy’s main offshore assets, and why is Uruguay oil and gas exploration so important?

Challenger Energy Group stands out as a “junior” company with a significant footprint in offshore Uruguay, and this region is crucial for the acquisition’s value. Their main focus has been on Uruguay, where they hold interests in two key blocks: AREA OFF-1 and AREA OFF-3. These blocks collectively span about 27,800 km² (with Challenger’s net share being around 19,000 km²), making them one of the biggest offshore acreage holders in the country. For Sintana, this means immediate access to a promising, emerging frontier for hydrocarbon exploration.

What is the AREA OFF-1 block, and how does Chevron’s partnership impact Uruguay’s offshore oil exploration?

The AREA OFF-1 block is a super important asset, stretching across about 14,557 km² in Uruguay’s shallow offshore waters. Its significance really soared in March 2024 when Challenger partnered with Chevron. Chevron now holds a 60% stake and will operate AREA OFF-1, while Challenger keeps a 40% non-operating interest. This deal was fantastic for Challenger, including:

• A US$12.5 million cash payment.
• Chevron covering 100% of Challenger’s share for a 3D seismic campaign, up to US$37.5 million (that’s US$15 million net to Challenger).
• Chevron also covering 50% of Challenger’s costs for the first exploration well, up to US$100 million (US$20 million net to Challenger).

Thanks to thorough work, three major prospects—Teru Teru, Anapero, and Lenteja—have been identified within AREA OFF-1, showing big resource potential. Environmental permits for a 3D seismic campaign are still in the works, but the plan is to start in late Q4 2025 or early Q1 2026. This partnership with Chevron makes future offshore oil exploration and development in this high-potential area much less risky, setting a strong base for the combined company’s expansion.

What’s unique about Challenger Energy’s AREA OFF-3 block, and what are its farmout prospects?

Adding to AREA OFF-1, the AREA OFF-3 block covers 13,252 km² in shallow to moderate waters, also offshore Uruguay. Challenger secured this license in June 2023 and currently operates it with a 100% interest. The first four-year exploration period, which kicked off in June 2024, has a pretty modest work commitment: reprocessing 1,250 km² of old 3D seismic data and doing some geotechnical studies. No drilling is required in this initial phase.

But Challenger didn’t just stick to the minimum. They sped up and expanded the technical work program for AREA OFF-3, much like they did with AREA OFF-1. This extra effort has already helped them find and map out two main prospects, Benteveo and Amalia, which have significant resource potential. Now that this early work is done, Challenger is looking for a partner for AREA OFF-3, aiming to find one in early 2026. This block offers great potential for Sintana to build on Challenger’s early success and bring in a strategic partner for future development. Understanding such resource management can be useful, especially when considering the advantages and disadvantages of natural gas as an energy source.

How does the acquisition expand Sintana Energy’s portfolio beyond Uruguay to Namibia and The Bahamas?

The acquisition of Challenger Energy isn’t just about Uruguay; it significantly expands Sintana Energy’s already varied portfolio. Sintana is already exploring and developing petroleum and natural gas in five promising onshore and offshore licenses in Namibia, plus in Colombia’s Magdalena Basin. Bringing Challenger into the fold adds their key Uruguay assets, along with insights from their past projects, like selling producing fields in Trinidad and their older exploration licenses offshore The Bahamas.

Even though the Bahamian licenses have their own hurdles (Challenger is looking at ways to get value from them or sort out legal issues), the combined portfolio offers a wider range of exposure. This means they’re active in different geological areas, with various operators and regulatory settings. This smart diversification helps reduce risk linked to any single asset and puts the new, merged company in a great spot to benefit from many exploration opportunities across the Southern Atlantic. This makes them a really interesting player in global oil and gas exploration. For a look at the bigger picture, consider the pros and cons of fossil fuels in the energy landscape.

What are the financial details of the Sintana Energy Challenger Energy deal, and how does it benefit shareholders?

The Sintana Energy Challenger Energy deal is an all-share acquisition. This means Challenger shareholders will receive about 0.4705 common shares of Sintana for each Challenger ordinary share they own. Looking at Sintana’s closing price on October 8, 2025, this deal values each Challenger Share at roughly 16.61 pence, or about Cdn$0.3105. That’s a pretty sweet deal, representing about a 44% premium over Challenger’s closing price on that date, and even better premiums compared to its average prices over the last three and six months.

Once the acquisition is complete, Challenger shareholders are set to own about 25% of the new, larger Sintana company. This gives them a meaningful share and a chance to benefit from the combined entity’s future successes. Plus, Sintana plans to list its shares on the AIM market of the London Stock Exchange in Q4 2025. This will make it easier to trade shares and increase visibility for all shareholders, both new and old. This financial approach truly highlights Sintana’s dedication to growing strategically and boosting shareholder value.

How will the leadership and governance of Sintana Energy change after the Challenger acquisition?

Integrating leadership and expertise is key to any successful acquisition. The Sintana Energy acquisition makes sure this transition is smooth by bringing top Challenger executives into Sintana’s team. Here’s how the new leadership will look:

• Eytan Uliel, Challenger’s CEO, will become President and executive director of Sintana.
• Iain McKendrick, Challenger’s Non-Executive Chairman, will join Sintana’s board as a non-executive director.
• Jonathan Gilmore, Challenger’s Finance Director, will step in as Sintana’s Chief Financial Officer.

This strategic reshuffle, combined with Sintana’s existing leadership, forms a powerful Board and management team. They’ll bring together extensive industry experience and commercial know-how, giving the company a real competitive edge. The knowledge and proven successes of these individuals will be vital in steering the enlarged company through its ambitious exploration and development projects, building a solid base for future growth and ensuring excellent corporate governance.

What regulatory approvals are needed for the Sintana Energy Challenger Energy acquisition?

For the acquisition to go through, it needs a bunch of approvals from regulators, stock exchanges, and shareholders. Here are the key ones:

• Approval from Challenger shareholders.
• Sanctioning of the Scheme by the Isle of Man Court.
• Conditional approvals from the TSX Venture Exchange (TSXV) for both the acquisition and Sintana’s planned AIM listing.
• Written approval from ANCAP (Uruguay’s national fuel, alcohol, and Portland administration).
• An exempt transaction notice from Chevron, as per their Joint Operating Agreement for AREA OFF-1.
• If needed, approval from the Bahamian Minister for petroleum and the Central Bank of The Bahamas.

Following the UK City Code on Takeovers and Mergers, a formal offer announcement (Rule 2.7 Announcement) has been released, detailing the offer and its conditions. Sintana is carefully working through these regulatory steps, and the acquisition is expected to wrap up by the end of Q4 2025. This will be a significant milestone for both companies.
