Board Governance

  • Independence: Ziemba is one of eight directors the Board determined independent under Nasdaq and SEC standards .
  • Committee assignments: HSES Committee Chair; Audit Committee member. HSES focuses on HSES systems, compliance, ESG/sustainability oversight, and risk trends; all HSES members are independent. Audit oversees external reporting, internal controls, financial risk; all members are independent and financially literate .
  • Attendance: In 2024, the Board met 5 times; Audit 8; Compensation 2; Governance 1; HSES 4. All directors attended all Board and applicable committee meetings on which they served .
  • Board structure: Combined CEO/Chair model with an independent Lead Director; the Board is majority independent by LLC agreement despite LP exemptions .
  • Conflicts process: The partnership agreement provides for a “conflicts committee” of at least two independent directors as circumstances warrant; matters approved are conclusively deemed fair and reasonable .

Equity Ownership

ItemDetail
Beneficial ownership – Ziemba68,230 Class A shares; less than 1% of Class A/B/C combined
Unvested equity19,550 phantom Class A shares outstanding (7,650 granted 2024; 11,900 prior), vest Aug 2025
Ownership guidelinesDirectors must hold securities equal to 5x annual cash retainer; “hold-until-met” on vested units; compliance date Nov 2025 (directors generally on track/already met)
Hedging/pledgingProhibited for directors and officers; no pledges reported for directors/NEOs as of Mar 24, 2025

Governance Assessment

  • Strengths:

    • Independent director; chairs HSES (ESG risk oversight) and serves on Audit; 100% attendance across Board/committees in 2024 .
    • Strong operating and technical background in refining/downstream, supporting asset integrity and safety oversight; skills matrix shows broad coverage including Energy Evolution .
    • Equity alignment via phantom shares and 5x retainer ownership guideline with hold-until-met; anti-hedging/anti-pledging in place .
  • Watch items / potential risks:

    • Director equity is time-based (no performance metrics), which may modestly weaken pay-for-performance signaling for directors versus performance-conditioned equity; however, this is common in director pay structures .
    • Broader Board transactions with EMG/EnCap were considered non-impairing to independence of those directors; no disclosures implicate Ziemba, but continued monitoring of related-party exposure is prudent .

Related Party & Conflicts

  • Policy framework: Governance Guidelines require disclosure of conflicts; resolution by disinterested directors or conflicts committee; Code of Business Conduct requires avoidance/disclosure of conflicts .
  • Transactions: 2024–2025 transactions with EMG- and EnCap-affiliated entities were reviewed; Board concluded no impact on independence of those directors. No related-party transaction disclosures involve Ziemba .

Compensation & Ownership Policies

  • Equity Ownership Guidelines: Directors must hold 5x annual cash retainer; compliance expected by Nov 2025; “hold-until-met” applies .
  • Anti-Hedging & Anti-Pledging: Prohibited for directors/officers; no pledges reported as of Mar 24, 2025 .
  • Clawback: Amended Nov 2023 to comply with Nasdaq/Dodd-Frank; applies to incentive-based compensation with triggers for material restatements (mandatory recovery) and detrimental conduct (discretionary recovery of performance/time-based awards) .

Signals for Investors

  • Alignment: Time-based phantom shares, hold-until-met ownership rules, and anti-hedging/pledging underscore alignment; Ziemba’s unvested phantom shares (19,550) further tie him to PAGP performance via equity value .
  • Effectiveness: 100% attendance and chairing HSES improve oversight credibility on safety/environmental risks—material for midstream valuation and risk premia .
  • Conflicts: No Ziemba-specific related-party transactions disclosed; Board-level conflicts processes are formalized, with use of conflicts committee as needed .
