CEO leads executive tax withholding wave. Builders FirstSource President & CEO Peter M. Jackson surrendered 8,508 shares at $88.09 per share on March 17, 2026, representing $749,470 in tax withholding on vested equity compensation. The transaction reduced his direct holdings to 272,332 shares.
Seven executives participate in coordinated filing. Eight Form 4 filings hit the SEC on March 17, covering 31,470 shares worth $2.77 million in aggregate tax withholdings across the executive team. Chief Operating Officer Stephen J Herron surrendered 5,818 shares ($512,508), while West Division President Scott L Robins gave up 5,057 shares ($445,471). EVP & CFO Pete Beckmann filed twice, covering a combined 3,839 shares ($338,178) in withholdings.
Transaction type signals routine equity vesting. All eight filings carry transaction code “F,” indicating shares withheld to satisfy tax obligations on vesting restricted stock or performance awards—not discretionary open-market sales. These transactions are automatic and do not reflect insider sentiment about the company’s prospects.
Insiders remain net buyers over six months. Despite the recent tax withholdings, Builders FirstSource insiders have purchased 50,000 shares and sold zero shares over the past six months, leaving net insider activity at +50,000 shares. The positive six-month trend suggests executives continue to accumulate equity beyond their compensation-driven transactions.
Institutional ownership remains concentrated. Vanguard Group holds 12.38 million shares (11% of the company), while BlackRock controls 8.88 million shares (8%). State Street rounds out the top three with 5.11 million shares (5%), providing a stable institutional base.
What to Watch: Monitor for additional Form 4 filings over the next 10 days as the annual equity vesting cycle completes. The six-month net buying trend of 50,000 shares suggests insiders view current levels as attractive—watch whether discretionary purchases resume after the tax withholding season concludes.
