FAQ

What insider transaction did GDYN CEO Leonard Livschitz report on August 21, 2026?

Leonard Livschitz reported a code F disposition of 174 GDYN common shares at $7.96 per share, representing shares delivered or withheld solely to cover tax withholding obligations associated with the vesting and settlement of restricted stock units.

Was the GDYN Form 4 transaction by Leonard Livschitz an open-market sale?

No. The Form 4 states the 174 GDYN shares were sold to cover tax withholding obligations in connection with the vesting and settlement of restricted stock units, which is reported as a code F tax-withholding disposition rather than a typical open-market sale.

How many GDYN shares does Leonard Livschitz hold directly after this Form 4?

After the reported events, Leonard Livschitz is shown as holding 3,355,528 shares of GDYN common stock directly, according to the holding entry in the Form 4, which lists total shares following the transaction for his direct ownership.

How many GDYN shares related to Leonard Livschitz are held indirectly through his spouse?

The Form 4 states that the indirect position is held by the reporting person’s spouse. After the 174-share tax-withholding disposition, that indirect holding totaled 10,834 GDYN common shares, as disclosed in the transaction row’s post-transaction share balance.

Was the GDYN CEO’s August 2026 Form 4 transaction under a Rule 10b5-1 trading plan?

The Form 4 shows the Rule 10b5-1 checkbox as unchecked, and no footnote describes a trading plan. The filing therefore does not indicate that the 174-share tax-withholding disposition occurred pursuant to a Rule 10b5-1 plan.

What is the significance of the code F transaction reported for GDYN on this Form 4?

The code F entry reflects 174 GDYN shares delivered or withheld at $7.96 per share to pay tax withholding obligations tied to restricted stock unit vesting, rather than a discretionary buy or sell decision in the open market.
