Governance Assessment

  • Alignment: Alexander consistently elects equity in lieu of cash retainers and receives annual RSUs, supporting skin‑in‑the‑game alignment with BLDR shareholders; beneficial ownership has trended up through 2025 while RSU balances decline as awards vest .
  • Effectiveness: Audit Committee financial expert with 100% meeting attendance in 2024; prior audit chair experience at BMC enhances BLDR’s oversight of financial reporting and auditor independence .
  • Independence/conflicts: Affirmed independent; external public board service within overboarding limits; no Alexander‑specific related‑party transactions disclosed; Audit Committee reviews any such matters under policy .
  • Compensation structure: Director pay emphasizes fixed retainers and time‑based RSUs with no performance metrics; policy increases in 2023 (retainer and RSU values) are modest and benchmarked by Meridian Compensation Partners; no options or repricing red flags .
  • RED FLAGS: None evident specific to Alexander. Historical supplier interlocks (PGT Innovations) were remediated by resignations in 2024; anti‑hedging/pledging policy reduces alignment risk; attendance at Audit Committee was 100% in 2024 .
