vest financial

"The LTIP Shares associated with the Grant are scheduled to vest in equal quarterly installments"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

board of directors financial

"received as compensation for the reporting person's service as a member of the issuer's board of directors"

They act like a team of advisors or managers, making sure the company stays on track and meets its goals. Their choices can influence the company's success and how it grows.

Remarks:

This Form 4/A is being filed to correct the vesting terms of the restricted shares previously reported by the Reporting Person. Due to a scrivener's error, the Reporting Person's prior Form 4 reported that the shares vest quarterly over a three-year period. The shares instead vest in equal quarterly installments over one year, as described in Footnote 1. No other changes have been made to the original Form 4.
