Restricted stock units financial
"On February 1, 2023, the reporting person was granted 33,803 restricted stock units, vesting 6/48ths..."
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.
tax-withholding disposition financial
"transaction_action": "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.
derivative security financial
"transaction_code_description": "Exercise or conversion of derivative security""
A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.
Irrevocable Trust financial
"Represents shares held by the Chandler D. Robinson Irrevocable Trust U/A dated May 20, 2020."
An irrevocable trust is a legal arrangement where an owner transfers assets into a separate entity managed by a trustee and gives up the power to modify or reclaim those assets. For investors it matters because putting stock or other holdings into such a trust can change who controls and benefits from the assets, affect taxes and creditor protection, and influence how easy it is to sell or value those holdings—like placing valuables in a locked safe overseen by someone else.
vesting financial
"Disposed of restricted stock units were surrendered in exchange for issuance of common stock upon vesting and settlement."
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
What insider transaction did Monopar Therapeutics (MNPR) report for its CEO?
Monopar Therapeutics CEO Chandler Robinson reported RSU vesting and related tax withholding. On June 30, 2026, 12,873 restricted stock units vested into common shares, and 4,084 of those shares were withheld by the issuer to satisfy tax obligations rather than sold on the open market.
What do the Monopar (MNPR) RSU grants in the footnotes indicate?
The footnotes describe multiple RSU grants with structured vesting schedules. Grants from February 1, 2023, March 4, 2025, and December 2, 2025 each vest in tranches through December 31, 2026, 2028, and 2029, respectively, delivering one common share for each vested restricted stock unit.
Is the Monopar (MNPR) CEO’s Form 4 a buy or sell signal?
The Form 4 reflects RSU vesting and tax withholding, not open-market trading. Shares were acquired through derivative exercises of restricted stock units, while 4,084 shares were withheld by the issuer for taxes, a routine mechanism that does not represent a discretionary market sale by the CEO.
