According to Protos, in March, Tether invested $134illion in NovaBay, a biopharmaceutical company experiencing financial difficulties. The source reports that following the deal, NovaBay became a holding company associated with the stablecoin USDS. The Protos headline also indicates that Tether has publicly disclosed a company that partially controls USDS.

The event is significant as it suggests a potential expansion of the corporate structure surrounding stablecoin assets beyond specialized cryptocurrency firms. However, the available material represents only a synopsis of the Protos publication, not a full set of documents or independent confirmation of the deal's terms.

It remains unclear what specific stake Tether acquired, how control over USDS is structured, and what functions NovaBay performs following the investment.
