Gordon Crystal L 4

What Happened
Gordon Crystal, Executive Vice President, General Counsel and Secretary of Gogo Inc., had 43,801 restricted stock units (RSUs) convert into 43,801 shares of common stock on March 21, 2026. To satisfy tax withholding, 12,592 of those shares were withheld at $4.26 per share, generating approximately $53,642 in tax payment. The RSU conversion/derivative cancellation is reflected as a 0.00 strike/value disposition entry for the derivative instrument.

Context
This was a routine RSU vesting and tax-withholding event (not an open-market purchase or discretionary sale). The withholding of shares to cover taxes is common and does not by itself signal a buy or sell decision in the market. The filing shows conversion of the derivative award and share withholding rather than a cash exercise or market trade.
