Chatkewitz Alexander 4

What Happened
Alexander Chatkewitz, Chief Accounting Officer of Wheels Up Experience Inc. (UP), had 4,240 shares of Class A common stock withheld on March 5, 2026 to satisfy tax withholding obligations arising from the vesting of restricted stock units (RSUs). The shares were valued at $0.56 each, resulting in $2,374 of shares withheld (transaction code F — tax withholding). This is a routine tax-related disposition rather than an open-market sale.

Key Details

• Transaction date and price: March 5, 2026; 4,240 shares @ $0.56 per share; total value ~$2,374.
• Transaction code: F (shares withheld to cover tax liability).
• Shares owned after the transaction: Not specified in the provided filing.
• Footnote: The withholding relates to RSUs issued under Wheels Up’s 2021 Long-Term Incentive Plan (amended and restated several times through March 26, 2025). The original grant was reported by the reporting person on Form 3 filed Sept 11, 2024.
• Filing timeliness: Report filed Mar 6, 2026 for a Mar 5, 2026 transaction — appears timely.

Context
Tax-withholding dispositions are common when RSUs vest: the company retains (or “surrenders”) a portion of the vested shares to cover required tax payments. These transactions are administrative and do not necessarily indicate the insider’s view on the company’s stock.
