Other Directorships & Interlocks

  • Current public/private boards: Crystal Clearwater Resources (Chairman), Oncor entities (Director) .
  • Network/Interlocks: ExxonMobil (via Pioneer) is a 16% shareholder (16.6M shares) and a major customer (2024 revenue ~$187.7M); Exxon designee Alex Volkov serves on the Board. Berg was formerly Pioneer’s designee but is now independent; nonetheless, the large customer/shareholder nexus is a continuing governance consideration .

Expertise & Qualifications

  • Strategic/M&A leadership (led Pioneer’s $65B sale to ExxonMobil; multiple multibillion-dollar M&A and JV transactions) .
  • Corporate operations oversight (completions/well services, water management, land, ESG) .
  • Legal/compliance (resolved SEC investigation, class action settlements at Hanover) .
  • Education: JD (UT Law, with honors); BA (Tulane, magna cum laude, Phi Beta Kappa) .

Equity Ownership

HolderShares Beneficially Owned% OutstandingNotes
Mark S. Berg28,728<1%As of 3/24/2025; includes RSUs vesting within 60 days per footnotes methodology
  • Stock ownership guidelines: Directors encouraged to hold ≥300% of annual cash retainer; Berg became subject to guidelines in 2024 and has five years to comply .
  • Company prohibits hedging/pledging of Company securities by directors and officers .

Governance Assessment

  • Strengths

    • Deep transactional, operational, and regulatory experience aligned with PUMP’s capital allocation, electrification, and ESG priorities .
    • Independence affirmed post-Pioneer–Exxon merger; sits on key governance/compensation committees, supporting board effectiveness and oversight .
    • Robust director compensation structure with time-based RSUs and clear stock ownership guidelines; broad clawback and anti-hedging/pledging policies at the company level .
  • Potential Risks / RED FLAGS

    • Customer/Shareholder concentration: ExxonMobil is both a major customer (~$187.7M 2024 revenue; $70.8M A/R at year-end) and ~16% shareholder, with a board designee (Volkov). Berg’s prior Pioneer affiliation is mitigated by his current independent status, but the overall Exxon nexus warrants ongoing monitoring for conflicts and recusal practices .
    • Related-party environment: While not involving Berg, the company discloses RPTs (e.g., facilities leased from an entity partly owned by a director and CEO’s father; significant spend with a vendor tied to an executive’s family), underscoring the need for rigorous audit oversight generally .
  • Shareholder Signals

    • Say-on-Pay: 2024 approval >98% indicates strong investor support for compensation governance; 2023 support dipped to 76% with subsequent engagement and program continuity by the committee (Berg joined the committee in Nov 2024) .

Insider Trades

  • The 2025 proxy lists beneficial ownership but does not detail recent Form 4 transactions for directors. No director-level Form 4 activity for Berg was identified in the proxy disclosures; for the latest insider transactions, a Form 4 search would be required outside the proxy .

Related Party & Conflicts Check (Berg-specific)

  • No Berg-specific related-party transactions disclosed in the 2025 proxy. Exxon/Pioneer context and board designee structure disclosed; Berg is no longer the designee and is classified independent .

Notes on Company Policies Impacting Governance

  • Clawback policy compliant with SEC/NYSE adopted Oct 11, 2023 .
  • Prohibition on hedging/pledging by directors and officers .
  • Director overboarding limits newly adopted to align with best practices .

Additional Context for Investors

  • Major customer/shareholder: ExxonMobil (includes Pioneer/XTO) — $187.7M revenue in 2024; $70.8M receivables at year-end; 16.6M shares owned .
  • Board refresh and rights: Exxon/Pioneer continues to designate one director (Volkov); board size reduced from ten to nine post-2025 AGM .

Overall, Berg brings high-value M&A and operational governance experience with independence reaffirmed post-Pioneer merger. The Exxon customer/shareholder nexus is the primary ongoing governance watch-point; current structures (independence, committee composition, policies) mitigate but warrant continuous oversight .
