Rhea-AI Filing Summary

WORKIVA INC director Martin J. Vanderploeg reported routine equity compensation activity. He received a grant of 4,070 restricted stock units of Class A Common Stock at no cost under the Workiva Inc. 2014 Equity Incentive Plan, which will vest in three equal annual installments starting on the first anniversary of the grant date.

To cover withholding taxes on previously granted restricted stock units that vested, 28,942 Class A shares were delivered back to the issuer at $52.83 per share; this is a tax-withholding disposition rather than an open-market sale. After these updates, he continues to hold substantial equity through direct Class A shares, indirect holdings in a living trust, stock options, and Class B shares convertible into Class A.

restricted stock units financial
"Shares delivered to the issuer for the payment of withholding taxes due upon the vesting of restricted stock units previously granted."
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
"Payment of exercise price or tax liability by delivering securities."
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.
Workiva Inc. 2014 Equity Incentive Plan financial
"Grant of restricted stock units pursuant to the Workiva Inc. 2014 Equity Incentive Plan."
Class B Common Stock financial
"Each share of Class B Common Stock is convertible, at any time at the election of the holder, into one share of Class A Common Stock."
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
convertible financial
"Each share of Class B Common Stock is convertible, at any time at the election of the holder, into one share of Class A Common Stock."
A convertible is a type of investment that starts as a loan or preferred stake (like a bond or preferred share) but can be exchanged for common shares of the company at a set price or under certain conditions. It matters to investors because it offers a mix of steady income and downside protection like a loan, plus the upside of stock ownership if the company does well—similar to holding a coupon that you can trade for a full ticket if the event becomes valuable.
