# Unitholder SoftVest files petition to amend PBT trust indenture; hearing set for May 8, 2026

## Summary
- SoftVest, owning 13.3% of PBT units, seeks to eliminate 75% supermajority vote requirement and allow amendments by majority vote.
- Current trust indenture prohibits amendments that would alter trust purpose or permit new investments, limiting ability to address royalty structure.
- Petition argues that drilling cost burdens on Waddell Ranch royalties have reduced distributions; no distributions since October 2024 despite rising revenues.
- Court hearing on merits scheduled for May 8, 2026 in Tarrant County District Court; SoftVest claims 98.5% unitholder support for its proposal at December 2025 special meeting.
