Binder Steven B. 4

What Happened

• Steven B. Binder, a director of MannKind Corporation (MNKD), had 82,781 restricted stock units (RSUs) reported as an acquisition (derivative) that vested on May 20, 2026. The Form 4 shows an acquisition price of $0.00 (no cash paid) because these were company awards that vested.
• Each RSU represents a contingent right to one share of MNKD common stock (see footnote). Although the RSUs vested on May 20, 2026, the actual shares will not be delivered until Binder separates from the board, so no shares were issued or sold at the time of the filing.

Key Details

• Transaction date: May 20, 2026; Form 4 filed: May 22, 2026 (filed within the standard two-business-day window).
• Transaction type/code: A (Award/Grant; derivative vesting of RSUs).
• Shares affected: 82,781 RSUs vested; acquisition price shown $0.00 (no cash exchanged).
• Shares owned after transaction: not specified in the provided filing data.
• Footnotes: F1 — each RSU equals a contingent right to one common share; F2 — RSUs vested May 20, 2026 but shares will be delivered only upon separation from the board.

Context

• This was a vesting of compensation (an award), not a purchase or sale — it does not by itself signal buying or selling sentiment. Because settlement is deferred until departure from the board, Binder cannot sell or transfer these underlying shares now.
• For retail investors, RSU vesting is a routine form of executive/director compensation. It’s factual information about insider holdings but not direct evidence of a change in the director’s market view.
