unvested shares financial

"Includes 974 unvested shares granted pursuant to the Five Star Bancorp 2021 Equity Incentive Plan"

Equity Incentive Plan financial

"granted pursuant to the Five Star Bancorp 2021 Equity Incentive Plan with all shares scheduled to vest"

An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.

indirect ownership financial

"total_shares_following_transaction marked as indirect with nature of ownership By self as trustee"

trustee financial

"Shares are held by The Riggs Family Trust dated May 11, 2006, for which Mr. Riggs serves as trustee"

A trustee is a person or institution legally appointed to hold and manage assets or enforce an agreement on behalf of other people (beneficiaries). Think of a trustee as a neutral referee or custodian who must act in the beneficiaries’ best interests, follow the trust or contract rules, and handle distributions, recordkeeping and enforcement. Investors care because a trustworthy trustee protects their rights, ensures promised payments or remedies are delivered, and can influence recoveries if things go wrong.
