Sintana Energy lists on LSE
Sintana Energy Inc. marked a major milestone on Tuesday when it rang the opening bell at the London Stock Exchange, celebrating its dual listing on the AIM market as investor interest in Namibia’s offshore oil prospects continues to grow.
The Canada-based exploration company, listed on the TSX Venture Exchange and now on AIM, began trading in London in December 2025 following its all-share acquisition of Challenger Energy Group. The move is aimed at broadening investor access and enhancing liquidity for shareholders, while elevating Sintana’s profile in global energy markets.
Sintana’s growth strategy is closely tied to Namibia’s Orange Basin, which has emerged as one of the world’s most closely watched oil frontiers after a string of major discoveries by international operators including Galp Energia, Shell plc and TotalEnergies.
The company holds indirect carried interests in several offshore petroleum exploration licences (PELs), including PEL 83, located near some of the basin’s most significant discoveries. These carried interests allow Sintana exposure to potential exploration upside while limiting capital expenditure obligations on certain blocks.
Katti’s strategic role
The company’s structure also underscores the growing role of Namibian participation in offshore exploration.
Namibian businessman Knowledge Katti serves as a non-executive director of Sintana and is founder and chief executive of Custos Energy (Pty) Ltd.. Sintana holds a 49% indirect interest in Custos Energy, which in turn has working interests in multiple Namibian PELs, including a 10% stake in PEL 83.
Katti controls a 51% majority stake in Custos Energy, creating a layered ownership structure that aligns local and international interests. Through his shareholding in Sintana and majority control of Custos, Katti occupies a strategically significant position in assets linked to Namibia’s offshore discoveries.
Custos has partnered with international players, including Galp and Chevron Corporation, reinforcing Namibia’s model of combining local equity participation with global technical and financial capacity.
Symbolic moment
Tuesday’s bell-ringing ceremony in London symbolises not only Sintana’s capital markets expansion but also increasing global confidence in Namibia’s Atlantic Margin potential.
As exploration activity intensifies and appraisal campaigns continue in the Orange Basin, the presence of Namibian stakeholders in upstream ownership structures is emerging as a defining feature of the country’s evolving petroleum landscape.
The dual listing is expected to strengthen Sintana’s access to international capital while positioning it to benefit from further developments in one of Africa’s most promising energy provinces.
