JACOBSEN RENE 4/A

What Happened
Rene Jacobsen, Chief Operating Officer of ABM Industries (ABM), had 1,007 shares withheld to satisfy tax obligations arising from the vesting of restricted stock units and relative-total shareholder return modified performance shares. The withholding occurred on January 10, 2026 at $44.69 per share, representing $45,003 in aggregate. This was a tax-withholding disposition (code F), a routine administrative action rather than an open-market sale or new purchase.

Context
Tax-withholding on vested awards is common and generally administrative—it reduces outstanding shares held by the insider to cover tax obligations and does not necessarily signal a change in the insider’s view of the company. This was not an open-market sale; shares were retained by the company to pay taxes related to equity awards.
