Restricted Stock Units financial
"Represents outstanding RSUs granted on October 3, 2023."
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

"The remaining unvested shares subject to the RSUs vest ratably in equal quarterly installments."
tax withholding financial
"1,553 shares of Lantronix, Inc. common stock were withheld at vesting to cover required 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.
RSU award agreements financial
"In accordance with the terms of the applicable RSU award agreements, 1,553 shares ... were withheld."
