Equity Ownership

HolderShares Beneficially Owned% of OutstandingNotes
Scott Sheffield104,166<1%As of Sept. 24, 2025; includes rights exercisable within 60 days; CDIs may represent shares

Context: Entities affiliated with Bryan Sheffield are the largest holder at TBN (17.5% at Sept. 24, 2025; 3,123,601 shares) via Sheffield Holdings LP and Daly Waters Energy LP per Schedule 13D amendments, separate from Scott Sheffield’s holdings .

Governance Assessment

  • Strengths
    • Deep operational and strategic expertise from decades leading Pioneer; adds sector credibility to TBN’s Sustainability oversight .
    • Board/committee engagement evidenced by meeting cadence and attendance expectations being met at the aggregate level .
  • Risks and RED FLAGS
    • Independence: The Board did not designate Scott Sheffield as independent and identified him (along with the Interim CEO) as having material relationships beyond board service—this is a governance red flag for committee composition and investor confidence in objective oversight .
    • Compensation structure: Large equity-in-lieu authorization (up to $200,000 per year) relative to current annual remuneration ($79,625) could increase guaranteed equity versus at-risk pay; however, director equity here replaces fees and is not performance-based, which may weaken pay-for-performance alignment for directors .
  • Signals to monitor
    • Any disclosures clarifying the nature of Sheffield’s “material relationship” and whether it impacts committee independence (especially Sustainability oversight) .
    • Actual elections to receive Director Securities (timing, amounts) and any subsequent RSU/stock award vesting details under the 2024 Equity Incentive Plan .
    • Changes in beneficial ownership or pledging/hedging policies and compliance (not specifically disclosed for Sheffield in the TBN proxy) .
