Hammerhead Resources Inc. Announces Equity Commitment

London, UK and Calgary, Canada (18 September 2018). Hammerhead Resources Inc. ("Hammerhead" or "HHR") has announced that it has secured a preferred share equity commitment of up to C$300 million that will provide financial flexibility to continue its organic growth program across its high quality resource base.

Hammerhead is a privately owned oil and gas producer focused on the liquids-rich Montney play in Alberta, and the largest investment of Riverstone Energy Limited ("REL" or the "Company"), representing 26.9% of the Company's gross assets as of 30 June 2018.

The preferred share equity commitment of up to C$300 million will be led by affiliates of Riverstone Holdings LLC ("Riverstone"), collectively HHR's largest shareholder. The financing will also feature a rights offering to certain existing common shareholders. REL owns approximately 31% of Hammerhead on a fully diluted basis and an announcement will be made in in due course regarding the extent of REL's participation in the preferred equity commitment, if any.

Proceeds from the equity commitment will be used to fund development activities principally in the Gold Creek and Karr areas, driving continued optimized capital efficiency with the use of multi-well pads in areas of existing infrastructure, combined with implementation of leading completion technologies. HHR believes that its balance sheet strength, industry-leading liquids growth, and secured firm egress differentiate the Company from its peers.

Hammerhead is currently producing over 28,000 boe/day, with a 42% weighting towards light oil and liquids. Annual production is expected to average over 27,000 boe/day in 2018, representing a 40% increase over 2017 levels. Since Riverstone's initial investment in 2014, the Company has increased production at a compound annual growth rate of over 70%, with a substantial corresponding increase in cash flow and reserves.

The Company will be releasing its quarterly portfolio valuations as of 30 September 2018 in October.
