Sintana Energy Schedules Live Management Presentation via Investor Meet Company on August 6, 2026

Sintana Energy’s Atlantic Margin Exploration Portfolio

Sintana Energy operates as an Atlantic Margin-focused exploration company active in key frontier regions along the Southern Atlantic conjugate margin. Its asset portfolio spans Namibia, Uruguay, and Angola, representing promising exploration opportunities in underexplored basins. The company benefits from strategic partnerships with major industry players, including significant carry arrangements that reduce its financial exposure during exploration and development phases.

Beyond its Atlantic Margin focus, Sintana Energy maintains legacy interests in Colombia and The Bahamas, offering exposure to established petroleum provinces. This geographic diversification mitigates concentration risk while providing access to varied exploration plays and regulatory environments. The company’s strategy targets high-impact assets in emerging frontiers with substantial discovery potential despite elevated geological risks.

CEO Robert Bose and President Eytan Uliel will directly address shareholders during the 6 August 2026 presentation.

Utilizing the Investor Meet Company platform accommodates investors across multiple time zones, with the 11:00 EDT / 16:00 BST timing serving North American and European audiences. Registration is free, and shareholders can submit questions in advance until 5 August 2026 or ask questions live, promoting inclusive participation.

The company’s geographically diverse shareholder base benefits from the virtual presentation format, enabling participation from investors in Canada, the UK, the US, and beyond without travel requirements.

Strategic Partnerships and Financial Carry Support

Sintana Energy’s operations are supported by strategic partnerships with major industry players across multiple jurisdictions. These partners provide significant carry support, funding exploration costs on Sintana’s behalf and reducing its capital expenditure during exploration phases. This approach is common in upstream oil and gas ventures, where costly drilling and seismic activities require shared financial responsibility.

Carry arrangements allow Sintana Energy to pursue high-risk exploration while managing its balance sheet effectively. Partnerships also provide access to technical expertise and operational resources that enhance project execution.

Exploration Focus on Frontier Basins in Emerging Markets

The company’s focus on frontier basins in Namibia, Uruguay, and Angola targets emerging regions with limited production history but significant undiscovered hydrocarbon potential. The Atlantic conjugate margin, spanning African and South American basins, has attracted increased exploration interest due to undrilled structural plays and new acreage availability. Namibia’s deepwater basins, in particular, have seen heightened industry activity following recent nearby successes.

Exploration in frontier basins involves substantial geological and commercial risks due to limited seismic data and production history. Success depends on accurate geological interpretation and discovery of commercially viable resources. Sintana Energy’s diversified presence across multiple jurisdictions helps spread exploration risk.

Annual General Meeting and Shareholder Communication Coordination

The management presentation follows immediately after Sintana Energy’s Annual General Meeting, combining formal governance with an interactive update. This scheduling maximizes shareholder engagement by consolidating company communications into a single event timeframe.

The presentation is open to all existing and potential shareholders, reflecting the company’s commitment to broad investor outreach and transparency through digital platforms.

Investor Meet Company Platform and Question Submission Process

The Investor Meet Company platform facilitates real-time interaction between Sintana Energy and its investors. Shareholders can submit questions in advance via their dashboard until 5 August 2026, allowing management to prepare detailed responses.

The platform centralizes investor communications, reducing email volume and maintaining a record of interactions. Offering both advance and live question options accommodates diverse investor preferences and enhances management’s ability to address shareholder concerns comprehensively.
