Rhea-AI Filing Summary

MannKind Corporation director Anthony C. Hooper reported equity-based compensation in the form of restricted stock units (RSUs). On May 20, 2026, he received an award of 16,556 RSUs, each representing a contingent right to one share of MannKind common stock, which vested that day but will only be delivered after he separates from the board.

On the same date, he also received a second grant of 82,781 RSUs in lieu of his annual cash retainer as a non-employee director. This award vests immediately, with share delivery likewise deferred until his separation from board service.

Restricted Stock Unit financial
"Each restricted stock unit represents a contingent right to receive one share of MNKD common stock."
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

"the shares will not be delivered until there is a separation of service from the board of directors of MannKind Corporation."
annual cash retainer payment financial
"Award granted in lieu of annual cash retainer payment for non-employee directors."
non-employee directors regulatory
"Award granted in lieu of annual cash retainer payment for non-employee directors."
Non-employee directors are board members who do not work for the company as salaried employees and usually do not hold day-to-day management roles. They act like outside referees or independent coaches, providing oversight, asking tough questions, and protecting shareholders’ interests; investors care because these directors help ensure management is accountable, reduce conflicts of interest, and influence decisions that affect company strategy and long-term value.
