Rhea-AI Filing Summary

PUMA MARY G reported acquisition or exercise transactions in this Form 4 filing.

Ciena Corporation director Mary G. Puma received an equity award of 605 shares of Common Stock as a grant of restricted stock units. These RSUs vest in full on the first anniversary of the grant date, meaning she will gain full ownership after one year if conditions are met. Following this award, she holds 11,477 shares directly, and this total includes unvested RSUs, so part of her position is still subject to vesting.

"Restricted stock units (RSUs) vest in full on the first anniversary"
Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.
