Restricted stock units financial
"Restricted stock units convert into common stock on a one-for-one basis."
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 obligations financial
"Represents shares withheld at the election of the Reporting Person to satisfy tax withholding obligations in connection with the vest of restricted stock units."
derivative security financial
"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.

FAQ

What insider transactions did Moderna (MRNA) report for Shannon Thyme Klinger?

Moderna reported that Chief Legal Officer Shannon Thyme Klinger had restricted stock units vest into common shares and simultaneously disposed of some shares to cover tax obligations, reflecting routine equity compensation activity rather than open-market buying or selling.

How many Moderna (MRNA) shares were acquired through RSU vesting in this Form 4?

The Form 4 shows 1,101 shares of Moderna common stock were acquired through the conversion of restricted stock units, split between 773 shares on May 27, 2026 and 328 shares on May 28, 2026, as part of scheduled vesting from prior equity awards.

Were the Moderna (MRNA) insider transactions open-market sales by Shannon Thyme Klinger?

No. The reported dispositions of 374 and 159 Moderna shares were tax-withholding transactions. Shares were withheld to satisfy tax obligations arising from RSU vesting, not sold in open-market trades, so they do not represent discretionary selling by the insider.

What prices are associated with the Moderna (MRNA) tax-withholding share dispositions?

The tax-withholding dispositions used share prices of $47.03 and $47.61 per Moderna share. These prices are used to value shares withheld to pay taxes due on the vesting of restricted stock units, rather than indicating separate open-market sales by the insider.

How do the restricted stock units reported by Moderna (MRNA) convert into shares?

The footnotes state that restricted stock units convert into Moderna common stock on a one-for-one basis. As specific vesting tranches are reached, each vested RSU automatically turns into one share of common stock, which is then reflected in the insider’s reported holdings.
