Corporate Controller Andrew J. Cebulla filed a Form 4 disclosing an F-code transaction on 06/09/2025, indicating shares were withheld to satisfy tax obligations arising from equity compensation. Key details are:

• Shares disposed (Code F): 489 common shares at an implied price of $70.38.
• Direct ownership after transaction: 1,638 common shares.
• Indirect ownership: 278 common shares held through a benefit-plan trust.
• No derivative securities were reported.

The total value of shares disposed is roughly $34,400, a negligible amount relative to the company’s market capitalization. No open-market purchase or sale occurred; the transaction was strictly tax-related. The filing does not signal any strategic shift or material change in insider sentiment.

Insights

Securities Analyst

TL;DR – Routine tax-withholding sale; immaterial to DCI valuation.

The Code F designation shows the officer surrendered 489 shares to cover taxes on vested equity, not a discretionary sale. Post-transaction holdings remain modest at 1,638 direct and 278 indirect shares, suggesting continued alignment with shareholders. Given Donaldson’s multi-billion-dollar market cap, the ~$34k value is de minimis and should not influence investment theses or trading dynamics. There is no indication of broader insider selling trends or fundamental concerns. Impact: neutral.
