restricted stock unit awards financial

"Vesting of restricted stock unit awards"

Restricted stock unit awards are company promises to deliver a specific number of shares to employees or service providers in the future once conditions—such as staying with the company for a set time or meeting performance targets—are met. They matter to investors because when the promises convert into actual shares they increase the total share count and can reduce earnings per share, while also aligning recipients’ interests with stock performance much like deferred pay that turns into ownership if goals are met.
