ESOP financial

"Includes shares allocated to the reporting person's account in the ESOP since the last filed Form 4, as of December 31, 2025."

An Employee Stock Ownership Plan (ESOP) is a program that gives employees ownership shares in their company, often as part of their benefits package. It acts like a company-sponsored savings plan, allowing workers to have a stake in the company's success, which can boost motivation and loyalty. For investors, ESOPs can influence company decisions and stock value, making them an important aspect of corporate ownership and governance.

Recognition and Retention Plan financial

"Includes 3,388 shares granted pursuant to the Issuer's 2022 Recognition and Retention Plan and Trust Agreement that reflect the unvested portion..."

tax-withholding disposition financial

"Payment of exercise price or tax liability by delivering securities"

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.

Stock Option (Right to Buy financial

"Stock Option (Right to Buy) with underlying Common Stock shares and stated exercise prices and expiration dates."

vesting at a rate of 20% per year financial

"These options are vesting at a rate of 20% per year that commenced on September 1, 2023."
