Owens Corning COO Todd Fister Withholds Shares for Taxes

What Happened
Todd W. Fister, President and Chief Operating Officer of Owens Corning (OC), had 1,180 shares withheld upon the vesting of restricted stock units to satisfy tax withholding obligations. The shares are recorded as disposed at a price of $128.67 per share, for a total value of $151,831. This was a tax-withholding disposal (code F), not an open-market sale.

Key Details

• Transaction date: 2026-09-15; Filing date: 2026-09-17 (filed within the normal Form 4 timing window).
• Shares withheld/disposed: 1,180 at $128.67 each; total value reported $151,831.
• Transaction type/code: F — shares withheld to satisfy tax withholding on vested RSUs.
• Post-transaction holdings: the filing does not state a specific total holding number; footnote F2 notes 219 shares were acquired on May 29, 2026 through the company ESPP (exempt under Rule 16b-3(c)) and are included in the holdings total.
• Footnotes: F1 explains shares were withheld upon RSU vesting to meet tax obligations; F2 documents the ESPP acquisition exemption.

Context: Tax-withholding disposals are routine when restricted stock units vest and do not necessarily indicate insider sentiment about the company. This was not an open-market sale or an exercise followed by a market sale — it’s a cashless tax withholding tied to compensation.
