tax-withholding disposition financial
"tax-withholding disposition at $16.98 per share to satisfy tax obligations"
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.
derivative exercise/conversion financial
"transaction_action is listed as derivative exercise/conversion for several option trades"
Stock Option (right to buy) financial
"security_title is Stock Option (right to buy) for the derivative entries"
beneficial ownership financial
"Shares owned by spouse of which reporting person disclaims beneficial ownership"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
401(k) Plan financial
"record keeper of the First US Bancshares, Inc. 401(k) Plan as of 6/29/2026"
A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
