More than a year after Mach Natural Resources LP announced a $1.3 billion acquisition of assets managed by IKAV Energy Inc., a Securities and Exchange Commission filing revealed IKAV, a foreign company, now owns more than 14% of Mach’s company shares.
The August 13, 2026 SEC filing showed the European-based company owns 23,631,109 shares or 14.2% of Mach. IKAV is an international asset management group that provides institutional investors with investment solutions spanning a broad range of infrastructure energy assets, including solar, concentrated solar power, wind, energy efficiency, geothermal, thermal power plants and upstream. The group was established in 2010 in Hamburg, Germany and now has offices in Luxembourg, Munich, Paris, Madrid, Lisbon, Milan, Rome, Palermo, Houston, Durango and New York. IKAV is a buy & hold investor with a vertically integrated business model to optimize its investment portfolio. The group has executed over 50 transactions since 2010.
The original announcement of the acquisition was made July 2025 and involved oil and gas assets from Sabinal Energy, LLC and entities owning oil and gas assets managed by IKAV Energy.
The announcement included a statement from Constantin von Wasserschleben, Chairman of IKAV.
“We are excited to transition IKAV’s San Juan assets into Mach Natural Resources and to become a significant shareholder of the Company. Mach’s strong industrial logic aligns with our long-term vision for this exceptional asset and beyond. The return of a public Company to the basin underscores the deep value and long-term potential of the asset. With our outstanding local team and the strength of Mach’s management team, we believe we can unlock even greater value in the basin. IKAV remains firmly committed to the belief that the world needs access to affordable and reliable energy.”
Mach Natural Resources LP announced it has entered into two separate definitive agreements: one to acquire certain oil and gas assets from Sabinal Energy, LLC , and another to acquire entities owning oil and gas assets managed by IKAV Energy Inc (collectively “IKAV San Juan”). The acquisitions increased Mach’s operations in the Permian Basin and San Juan Basin entry. They also nearly doubled Mach’s production of oil and increased its gas exposure to nearly 66%. The acquisitions also added about 700,000 net acres, increasing Mach’s total acreage by 33% to 2.8 million acres.
