Builders FirstSource (BLDR) Director James O'Leary Receives Award

What Happened

Key Details

  • Transaction date: 2026-05-14; Filing date: 2026-05-18 (filed within the typical Form 4 timing window).
  • Transaction type/code: A = Award/Grant of restricted stock units.
  • Amount: 2,558 RSUs; reported acquisition price: $0.00.
  • Shares owned after transaction: Not disclosed in the filing.
  • Footnote: The RSUs were granted under the company’s 2014 Incentive Plan and vest on May 14, 2027, with each RSU entitled to one share upon vesting.

Context

  • This is a compensation-related equity grant (an award), not a market purchase or sale, so it does not reflect an immediate cash investment or disposition by the director.
  • RSUs typically represent future stock delivery upon vesting and are commonly used for long-term incentive pay; they do not change share ownership until they vest.
