"Pursuant with a net settlement, shares of stock were tendered"

tax withholding financial

"shares of stock were tendered to pay for the 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.

code F transaction financial

"Payment of tax liability by delivering or withholding securities"

Form 4 regulatory

"director Kelli Bernard reported a Form 4 transaction"

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.

Was the OSIS Form 4 transaction by Kelli Bernard made under a Rule 10b5-1 plan?
