Company Overview
We are an independent refiner focused on operating safely and efficiently.
Our business strategy is to create long-term value through disciplined investment, operational excellence, and commercial optimisation of vital energy assets around the world.
Our refineries process more than 142 million barrels per year and we employ more than 2,700 people in locations internationally including the UK, Switzerland, Malta, Denmark and Germany. We are successful at what we do and have a 25-year track record of acquisitions from companies including Equinor, Aegon, Alcan, Deutsche Telekom, Dynegy, Tata, Shell and bp.
Our approach: Careful investment, rigorous asset optimisation, and best-in-class risk mitigation.
We protect the value of our assets by combining intensive operational optimisation and prudent investment internally with an expansive strategy of external risk mitigation.
We manage operational risks across the business through procedures to minimise losses, conducting regular audits and evaluating the security and strength of our IT, as well as our other operational processes and assets.
We view all acquisitions as long-term strategic investments. We acquire ‘non-core’ industrial assets from public and private companies. We look for businesses that may be underperforming, but are stable and have strong fundamentals. The breadth of our expertise allows us to continuously evaluate opportunities across the petroleum sector and broader energy transition.

We are a cornerstone of reliable energy supply for the countries we serve today. We fuel almost all flights departing from Hamburg airport; heat over 250,000 homes in Northern Germany and directly supply petrol and diesel to large parts of Denmark.
Our commitment to innovation means that as the energy landscape evolves, we will be just as vigilant in providing energy and mobility to the communities that will rely on us tomorrow.

Our Investment Approach
Our expertise is in acquiring businesses in high-cost, highly regulated environments where long-term demand remains robust.
We aim to expand our activities in geographies where we can optimise new assets and operate as responsible business owners. In assessing these investments, we are rigorous in considering the political, regulatory, and commercial landscape and the implications of the ongoing energy transition. We seek to have a positive impact and create growth over the long-term in the markets where we operate.
The crux of our success is that our refineries benefit from being ‘core’ within our business vs. being a ‘legacy asset’ within a larger organisation. For us, the successful operation of our refineries determines our overall performance. We are diligent in ensuring our refineries are operationally optimised while also ensuring we are proactively managing external risk.
Further, we also invest capital to ensure the topline performance of our assets. To date, we have invested $650 million in enhancing and improving our Heide and Kalundborg refineries.
