Full Year Results

Harbour Energy today announces its audited full year results for the year ended 31 December 2022.

Linda Z Cook, Chief Executive Officer, commented:

"In our first full year as a publicly listed company, Harbour delivered materially higher production which - together with improved margins - enabled us to continue to deleverage and make material shareholder distributions. We further developed our Net Zero strategy, setting ourselves an interim target, and built significant momentum in our flagship Viking CCS project. Most importantly we achieved all of this while improving our safety record.

However, the UK Energy Profits Levy, which applies irrespective of actual or realised commodity prices, has disproportionately impacted the UK-focused independent oil and gas companies that are critical for domestic energy security. For Harbour, the UK's largest oil and gas producer, it has all but wiped out our profit for the year. This has driven us to reduce our UK investment and staffing levels. Given the fiscal instability and outlook for investment in the country, it has also reinforced our strategic goal to grow and diversify internationally.

Thanks to our robust balance sheet, we enter 2023 well-placed to deliver on our strategy of building a global diverse oil and gas company. We will continue to return any excess capital to shareholders while investing in our existing portfolio and maintaining capacity for meaningful but disciplined M&A."

1 The $1 billion of free cash flow is after tax payments and reflects that the majority of our 2023 EPL liability is expected to be paid in 2024 due to one of the Harbour entities not currently falling within the UK tax instalment payment regime.
