Boydston Cory Jacobs 4

What Happened

• Cory Boydston, a director of Builders FirstSource, was granted 2,558 restricted stock units (RSUs) on May 14, 2026. The award is reported at a grant price of $0.00 (no cash paid) and will convert to one share of common stock per RSU when vested.
• This is an equity award (A = Award/Grant), not an open-market purchase or sale. Such awards are routine compensation/retention tools and do not by themselves signal a purchase or sale of existing shares.

Key Details

• Transaction date: 2026-05-14; Form 4 filed: 2026-05-18 (timely filing).
• Award: 2,558 restricted stock units (RSUs) at $0.00 per unit; total reported cash value of grant = $0 on the Form 4.
• Vesting: RSUs vest on May 14, 2027 and each vested RSU entitles the holder to one share of common stock (footnote F1).
• Shares owned after transaction: not specified in the provided filing excerpt.
• No 10b5-1 plan, tax-withholding sale, or immediate sale noted in this filing.

Context

• RSUs are a deferred equity award: the recipient does not receive shares until the RSUs vest (here, one year later). They are common for directors and executives as compensation and retention incentives.
• Because this is a grant (award) rather than a purchase or sale, it should be interpreted as compensation-related, not a direct insider market bet.
