Murphy Mark W. 4/A

What Happened

• Mark W. Murphy, EVP & Chief Information & Digital Officer of 3M (MMM), had 4,793.011 shares withheld on 2026-02-02 to satisfy a tax liability related to prior equity awards (transaction code F). The filing shows the shares were disposed with a reported price of $0.00 and total proceeds $0 — this reflects a tax-withholding transaction, not an open-market sale.

Key Details

• Transaction date: 2026-02-02 (amended Form 4 filed 2026-02-18)
• Transaction type: F — payment of exercise price or tax liability (shares withheld)
• Shares withheld/disposed: 4,793.011 shares at $0.00; reported proceeds $0
• Shares owned after the transaction: not specified in this amended filing
• Footnote: The original Form 4 used an estimated number of shares withheld; this amendment updates the report with the actual number withheld (F1)
• Timeliness: This is an amended filing dated 2026-02-18 updating the Feb 2 transaction; the amendment itself was filed later than the transaction but simply corrects the previously estimated withholding amount

Context

• Withholding of shares to cover taxes is a routine administrative step when restricted stock or option exercises generate tax liabilities. It is not an open-market sale and generally does not signal a change in the insider’s view of the company. The amendment only revises the actual number of shares withheld and does not indicate any additional trading.
