Thanks for the correction Scott. I had a quick google and it looks like Masan kept the stake in Nyobolt they paid $54m USD for in 2022

Mitsubishi Materials Corporation (MMC)
Masan High-Tech Materials (MHT)

"Under the agreement, MMC will acquire 100% ownership of HC Starck Tungsten, including its three tungsten processing plants. However, MHT will retain ownership of Nyobolt, a UK-based battery research company owned by HC Starck Tungsten. Additionally, MHT is expected to retain potential profits from future commercial black mass recycling technology developed by HC Starck Tungsten. "
