What insider transactions did CELH Chief Legal Officer report on February 27, 2026?

The CELH Chief Legal Officer reported a tax-withholding disposition and an RSU grant. 3,416 shares were withheld to cover tax obligations, and 8,813 restricted stock units were granted, each representing one future share of common stock, vesting over three years.

Was the CELH insider transaction a buy or sell of common stock?

The CELH filing shows a mixed activity: a tax-withholding disposition and an RSU award. Shares were not sold on the open market; instead, 3,416 shares were withheld for taxes while 8,813 RSUs were granted as equity compensation.

How many Celsius Holdings shares does the reporting person hold after these transactions?

After the reported transactions, the CELH Chief Legal Officer directly holds 44,253 shares of common stock. This figure reflects both the tax-related share withholding and the new restricted stock unit grant reported in the Form 4 filing.

What are the terms of the CELH restricted stock units granted on February 27, 2026?

The CELH restricted stock units grant covers 8,813 RSUs, each equal to one common share. These RSUs vest in three equal annual installments, beginning on the first anniversary of the grant date, providing a multi-year equity incentive for the reporting person.

Why were 3,416 CELH shares disposed of in the Form 4 filing?

The 3,416 CELH shares were withheld to satisfy tax withholding obligations triggered by RSU vesting. This tax-withholding disposition, coded “F,” settles required taxes using shares rather than a separate cash payment by the reporting person.

Did the CELH insider pay cash for the 8,813 restricted stock units?

The 8,813 CELH restricted stock units were granted at a reported price of $0.00 per share. This indicates an equity compensation award, where the reporting person receives RSUs without an upfront cash payment, subject to the specified vesting schedule.
