stock units financial

"In lieu of receiving cash fees, the reporting person received 165 stock units, which immediately vested"

Stock units are individual pieces of ownership in a company, like slices of a pie that together make up the whole business. They matter to investors because each unit represents a claim on the company’s assets, profits and sometimes voting power, and changes in the number or value of these units affect ownership percentages, potential dividends and share dilution — all of which influence an investment’s worth.

"This amount reflects a matching stock unit contribution by EnerSys for the reporting person's account in the Plan"

Termination financial
