Insights

Large project-level notes financing priced at 7.250% through a majority-owned affiliate.

TeraWulf highlights that Flash Compute LLC has priced $1.3 billion aggregate principal amount of senior secured notes due 2030, upsized from $1.275 billion. The offering is conducted as a private placement to institutional and non-U.S. investors under Rule 144A and Regulation S, which is a common route for large, secured note deals tied to infrastructure or capital-intensive projects.

Flash Compute sits within a layered ownership structure: it is wholly owned by FS CS I LLC, which is in turn owned 50.1% by Big Country Wulf LLC, a subsidiary of TeraWulf, and 49.9% by Fluidstack CS I Inc. This means the new notes are associated with an entity TeraWulf indirectly controls but shares economically with another partner. The expected closing on December 29, 2025 remains subject to market and other conditions, and forward-looking language underscores that completion, size, timing, and use of proceeds could differ from current expectations.
