tax-withholding disposition financial
"41 shares of common stock were withheld at $14.50 per share to cover tax obligations, a non‑market transaction coded as a tax-withholding disposition."
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.
ESOP financial
"Cornish directly held 3,003 common shares, plus indirect holdings of 1,478 shares through an ESOP and 25,816 shares through a 401(k)."
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.
401(k) financial
"He also had indirect holdings of 1,478 shares through an ESOP and 25,816 shares through a 401(k), plus stock options tied to an additional 9,302 underlying shares."
A 401(k) is a type of retirement savings plan offered by employers that allows workers to set aside a portion of their paycheck before taxes are taken out. The money saved in a 401(k) can grow over time through investments, helping individuals build funds for their future retirement. It matters to investors because it provides a tax-advantaged way to save and invest for long-term financial security.
stock options financial
"Cornish also held stock options over 4,804 shares at $6.48 expiring on May 16, 2033 and 4,498 shares at $8.13 expiring on June 28, 2032."
Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.
restricted stock financial
"Includes shares of restricted stock which vest at a rate of 20% per year commencing on June 28, 2023."
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.
