Riverstone Energy Limited Purchases Interest in a Samsung Ventures Portfolio

London, UK (17 August 2021).  Riverstone Energy Limited ("REL") has purchased an interest in one of Samsung Ventures' battery technology focused venture capital portfolios (the "Samsung Portfolio") for $30.0 million. The remaining interest was purchased by Riverstone affiliates for $3.0 million. The Samsung Portfolio consists of seven unrealised investments with the majority of value deriving from over 1.66 million shares of Solid Power, Inc ("Solid Power").

On 15 June 2021, Solid Power, an industry-leading producer of all-solid-state rechargeable batteries for electric vehicles and mobile power markets, announced a merger with Decarbonization Plus Acquisition Corporation III ("DCRC"). REL owns founder shares and warrants in DCRC and has a commitment to purchase $20 million of DCRC common stock in a private placement transaction at $10 per share. Assuming $10 per share of DCRC common stock, the Samsung Portfolio's Solid Power shares would be valued at approximately $64 million.

This investment, along with the recent decarbonisation investments in Decarbonization Plus Acquisition Corporation II, III & IV, FreeWire Technologies, GoodLeap (formerly Loanpal) and Hyzon Motors, demonstrates REL's continued efforts to increase its exposure to the global energy transition thematic while also providing the opportunity to create value for its shareholders.
