SCHNEIDER ANDREA L 4

What Happened

• Andrea L. Schneider, President & CEO of Horizon Airlines, had 2,786 restricted stock units (RSUs vest) for Alaska Air Group (ALK) on Feb 11, 2026. The RSUs converted to 2,786 shares (exercise/conversion, code M). To satisfy tax withholding, 632 of those shares were surrendered/disposed at $57.50 per share, generating $36,340 in withholding. Net shares received by Schneider from this vesting were 2,154 shares (2,786 vested − 632 withheld). The $0 price on the RSU conversion reflects that these were vested awards, not a cash purchase.

Context

• This was an award vesting with routine share withholding to meet tax obligations, not an open-market sale or purchase. The conversion of RSUs to shares (code M) followed by withholding (code F) is a common, administrative transaction and does not necessarily indicate a change in the insider’s market view.
