RockRose Energy was founded in 2015 to identify onshore and offshore production opportunities and infrastructure projects. Focused on building a low-cost E&P business of scale, the Company grew rapidly through the acquisition of packages of non-operated assets, predominantly in the UK North Sea. Early acquisitions included the purchase of asset interests from Egerton Energy Ventures, Sojitz Energy, and Idemitsu in 2017. The production and cash flow provided by these deals created a solid platform for further expansion.

In May 2018, RockRose agreed to acquire a package of non-operated producing assets from the Dyas group of companies for €107 million. On completion in October 2018, this transaction increased Group output to over 10,000 boepd.

In October 2020 Viaro Energy acquired RockRose Energy and brought the company private. In early 2021 RockRose completed the acquisition of HaLO to bring producing assets in the Netherlands into the portfolio. In October 2021 Viaro completed the acquisition of SSE E&P to bring the group output to over 30,000 boepd.

Viaro/RockRose is well placed to grow from a stable and secure base production and will continue to evaluate opportunities both in the UK North Sea and Worldwide.
