FAQ

What insider transaction did ATR CEO Stephan B. Tanda report on this Form 4?

Stephan B. Tanda reported a tax-withholding disposition of 1,321 shares of AptarGroup common stock. The shares, valued at $144.14 each, were withheld to satisfy tax obligations, rather than representing an open-market sale, which is a common mechanism for equity compensation.

Did the ATR Form 4 filing show an open-market sale by the CEO?

The filing did not show an open-market sale by the CEO. It reported a code “F” transaction, meaning 1,321 shares were disposed of to pay taxes due on equity compensation, a routine, non-discretionary event rather than a voluntary buy or sell decision in the market.

How many ATR shares does Stephan B. Tanda hold after the reported transactions?

After the reported transactions, Stephan B. Tanda directly holds 202,678 AptarGroup common shares. He also has an indirect holding of 3,127 shares through a 401(k) trust, reflecting both direct ownership and retirement-plan-related beneficial interests disclosed in the Form 4 data.

What does transaction code F mean in the ATR CEO’s Form 4?

Transaction code F indicates payment of a tax liability by delivering or withholding securities. In this case, 1,321 AptarGroup shares were used to cover taxes tied to equity awards, so it is a tax-withholding disposition instead of a typical market purchase or sale transaction.

How are ATR shares in the 401(k) trust classified in the Form 4?

Shares in the 401(k) trust are reported as indirect ownership. The Form 4 shows 3,127 AptarGroup shares held “By 401(k) trust,” separate from Tanda’s 202,678 directly owned shares, clarifying that some beneficial ownership is through a retirement-plan-related vehicle rather than personal accounts.
