[SCHEDULE 13D/A] PERMIAN BASIN ROYALTY TRUST SEC Filing

Rhea-AI Filing Summary

SoftVest-affiliated parties report beneficial ownership of 6,217,107 Units, representing 13.3% of Permian Basin Royalty Trust (PBT). The filing amends a prior Schedule 13D to add disclosure about short put options held by SoftVest, L.P.: $12.50-strike puts on 396,500 Units (3,965 contracts) and a $15.00-strike put on 100 Units, each expiring on 12/19/2025. The reporting persons include SoftVest Advisors, LLC; SoftVest GP I, LLC; SoftVest, L.P.; and Eric L. Oliver, who collectively report shared voting and dispositive power over the disclosed units. The amendment states the percentage calculation is based on 46,608,796 Units outstanding as reported in the issuer's SEC filing dated 8/13/2025.

Positive

• Beneficial ownership disclosed: 6,217,107 Units (13.3%) — a sizable, clearly reported stake
• Amendment increases transparency by adding details on short put positions and strikes

Negative

• Short put positions create contingent purchase obligations at $12.50 and $15.00 if exercised on 12/19/2025
• Shared voting/dispositive power across related entities concentrates control and could raise governance questions for other unitholders

Insights

Institutional Ownership Analyst

SoftVest group holds a meaningful 13.3% stake and reports derivative exposure.

The group reports beneficial ownership of 6,217,107 Units, equal to 13.3% of the outstanding units, which is large enough to influence voting outcomes on trust matters. Shared voting and dispositive power is disclosed across affiliated entities and an individual, indicating coordinated ownership and control.

The amended disclosure adds short put positions exercisable at $12.50 and $15.00 expiring on 12/19/2025, which could affect net exposure depending on unit price near expiry. Monitor unit trading around that date for potential exercise or assignment activity.

Derivatives / Risk Analyst

Short put exposure creates contingent obligations if unit prices fall before 12/19/2025.

SoftVest, L.P. has short puts referencing 396,600 Units in aggregate across two strikes ($12.50 and $15.00), which could require purchasing units if exercises occur. The notional referenced (396,600 Units) is small relative to the 6.22M owned but creates upside risk if units decline below strikes.

The positions expire on 12/19/2025; near-term price moves below the strikes would materially change SoftVest's net long/short exposure. Watch market price of units into December 2025 for potential assignment activity.
