deferred restricted stock units financial

"The deferred restricted stock units were awarded under the 2019 Non-Employee Director Stock Plan."

Deferred restricted stock units are promises by a company to give employees or executives company shares at a future date, subject to conditions like continued employment or performance targets; the delivery and tax event are intentionally delayed. They matter to investors because they affect when new shares may be issued and how executives are motivated—like a paycheck held in escrow that vests over time, influencing potential share dilution and management behavior.
