Kay Sabrina 4

What Happened

• Kay Sabrina, a director of MannKind Corporation (MNKD), had 82,781 restricted stock units (RSUs) recorded as an award/vest on May 20, 2026. The filing shows acquisition of 82,781 derivative shares at $0.00 per share — this reflects RSU vesting rather than a cash purchase or open-market trade. The vested units are contingent rights to common stock but the actual shares will not be delivered until she separates from the board.

Key Details

• Transaction date: May 20, 2026; Form 4 filed May 22, 2026 (within the typical 2-business-day reporting window).
• Instrument/type: Restricted stock units (derivative award), code A (award/acquisition).
• Amount recorded: 82,781 RSUs acquired at $0.00 per share (vesting event, no cash exchanged).
• Shares owned after transaction: The filing does not state a clear total; it notes that 158,567 deferred RSUs were inadvertently included in prior filings' holdings and corrects that error (see footnote).
• Footnotes: F2 confirms each RSU equals a contingent right to one share. F3 states the RSUs vested on May 20, 2026 but shares won’t be delivered until separation of service.
• No 10b5-1 plan, sale, or tax-withholding transaction is indicated in this filing.

Context

• This was a vesting of RSUs (an award becoming earned), not an open-market buy or sale. Because delivery is deferred until separation from service, the transaction does not immediately change the tradable share count held by the director.
• Vesting events are common executive compensation mechanics and are informational rather than a direct bullish or bearish market signal.
