Prentiss Christopher B 4

What Happened
Christopher B. Prentiss, Chief Financial Officer of MannKind Corporation (MNKD), was granted two restricted stock unit (RSU) awards totaling 438,000 units on March 23, 2026 (221,000 and 217,000). The grants are reported as derivative awards (transaction code A) at $0.00 per unit, meaning these are equity awards rather than open-market purchases or sales.

Key Details

• Transaction date: March 23, 2026; Form filed March 25, 2026 (covers the 3/23/2026 transaction).
• Award amounts: 221,000 RSUs and 217,000 RSUs (total 438,000 RSUs). Reported acquisition price: $0.00 (grant).
• Each RSU represents a contingent right to receive one share of MNKD common stock (footnote F1).
• One grant is performance-based and vests (if earned) on January 15, 2029 based on MannKind’s total shareholder return vs. the Russell 3000 Pharmaceutical & Biotechnology Index, with potential payout from 0% up to 300% of target depending on percentile ranking (footnote F2).

• Filing appears timely (reported within two business days of the transaction date).

Context
These awards are equity compensation (derivative RSUs), not purchases or sales. Performance-based RSUs will only convert to shares if performance hurdles are met; time-based RSUs vest over several periods. Such grants are common for executives as retention and performance incentives and do not by themselves indicate immediate buying or selling of stock.
