5 terms

restricted stock financial

"Award of restricted stock which vested on April 1, 2026"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

tax withholding financial

"Shares withheld on vesting of restricted stock award to cover tax withholding"

Tax withholding is the practice of taking a portion of a payment—such as wages, dividends, or sale proceeds—before it reaches the recipient and sending that portion to the tax authority as an advance on the recipient’s eventual tax bill. For investors it matters because withholding reduces immediate cash received and affects after‑tax returns, estimated tax payments, and whether you may owe more or receive a refund when taxes are finally calculated, like having a small automatic savings set aside for your tax bill.

trustee financial

"over which the Reporting Person 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.

co-trustee financial

"over which the Reporting Person serves as co-trustee"

beneficiaries financial

"The Reporting Person and a member of the Reporting Person's immediate family are the beneficiaries of this trust"

Beneficiaries are the people or organizations designated to receive benefits, such as money or assets, from a financial arrangement like a trust, insurance policy, or retirement plan. They matter to investors because choosing the right beneficiaries ensures that assets are passed on according to their wishes, providing financial security or support to loved ones when needed. Think of beneficiaries as the intended recipients of a gift or inheritance.
