Insights

RTW reports a 48.1% stake and restructures claims into preferred.

The amendment shows RTW as a major holder with 5,891,430 shares beneficially owned, calculated against 12,249,232 shares outstanding at the private placement close. It details a liability-for-equity exchange: remaining notes plus $48.0 million and $9.5 million under revenue interest agreements will convert into Series B Preferred.

The preferred carries an 8.25% dividend and a conversion price of $3.37, with a 9.9% beneficial ownership conversion cap. The closing is conditioned on stockholder approval and listing compliance, so timing depends on those approvals. The concurrent private placement added 1,856,288 shares and warrants at $1.67 for about $3.1 million.

Governance rights include board nominations at 10% and 30% ownership thresholds, and additional rights during a specified breach tied to a $3.0 million minimum cash balance and an FDA marketing authorization by December 31, 2026.
