Energy Holdings and Ventura Offshore to combine, creating a larger platform for cash generation, shareholder distributions and growth

Ventura Offshore Midco Ltd, 11 September 2026: SED Energy Holdings Plc (“Energy Holdings”) and Ventura Offshore Holding Ltd. (“Ventura Offshore”) today announced that they have signed a letter of intent (the “LOI”) for an all-share combination between the two companies (the “Transaction”).

The Transaction will combine Energy Holdings and Ventura Offshore to create a larger and stronger publicly listed energy services platform. Following completion, Energy Holdings will remain the listed parent company, with Ventura Offshore continuing as a dedicated deepwater drilling vertical alongside Energy Drilling and SeaBird Exploration. Together, the businesses will form a broader portfolio of cash-generative assets with approximately USD 1.3 billion of contracted revenue backlog, providing greater scale, diversification and financial flexibility.

Since its establishment, Energy Holdings has returned USD 132.5 million to shareholders, equivalent to approximately 30% of its market capitalization at inception, while reducing debt and maintaining a conservative financial profile. The combined company intends to retain this capital allocation philosophy, with shareholder distributions remaining a core pillar of the strategy. The combination is expected to strengthen the earnings and cash flow base supporting future distributions and enhance the company’s capacity to return capital to shareholders over time.

“Energy Holdings was established with a clear ambition to build a portfolio of high-quality, cash-generative energy services businesses and create value through disciplined capital allocation. Ventura is an excellent fit with that strategy – a high-quality business with experienced management team, substantial contracted cash flows and exposure to an attractive offshore market,” says Kurt M. Waldeland, CEO of Energy Holdings.

“Ventura has built a strong deepwater drilling business with high-quality assets, an experienced organization, long-standing customer relationships and substantial contracted backlog. By combining with Energy Holdings, our shareholders will continue to participate fully in Ventura’s future while also gaining exposure to a larger and more diversified portfolio of cash-generative businesses. The combination will also provide greater financial flexibility to pursue attractive growth opportunities in the offshore drilling sector,” says Guilherme Coelho, CEO of Ventura Offshore.

The parties expect the combination to create significant benefits through increased scale, disciplined capital allocation and an enhanced financing and capital markets profile. The larger and more diversified earnings base is expected to strengthen the combined group’s credit profile, increase relevance in the debt and equity capital markets and create a stronger platform for both shareholder distributions and further accretive growth.

Mr Waldeland further highlights the strategic rationale of the contemplated combination;

“The transaction is expected to enable incremental growth opportunities that Energy Holdings and Ventura Offshore would not be able to pursue on a stand-alone basis, both within our existing verticals and in adjacent offshore services markets. We also expect the combined company to unlock significant financial synergies, including through a more efficient debt structure and the potential for non-amortizing debt, which could materially increase distribution capacity. Finally, following completion, we expect the new Board to initiate a process to consider a potential US dual-listing and IPO of Energy Holdings.”
