Insights

Equity compensation analyst

Routine option exercise with tax withholding, no open-market trade.

Director Donal L. Mulligan exercised fully vested options for 3,538 Tennant Co shares at $54.70. This converts a derivative award into common stock and is a typical part of equity compensation, not an open-market purchase.

To satisfy tax obligations, 2,456 shares were used at a value of $78.81 per share, classified as a tax-withholding disposition rather than a market sale. Afterward, he holds 20,685 shares directly plus 8,000 shares indirectly via a spouse’s trust, indicating a continuing equity stake.

"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.

Did Donal Mulligan sell Tennant Co (TNC) shares on the open market?

The filing shows no open-market sale. Instead, 2,456 shares were withheld at $78.81 per share to pay taxes related to the option exercise. This tax-withholding disposition is a standard mechanism and differs from selling shares to other investors in the market.

How many Tennant Co (TNC) options did Donal Mulligan exercise and at what price?

He exercised stock options covering 3,538 Tennant Co common shares at an exercise price of $54.70 per share. These options were fully vested and converted into common stock, increasing his direct share ownership before the separate tax-withholding transaction reduced the net shares received.

After the transactions, Mulligan holds 20,685 Tennant Co common shares directly. In addition, 8,000 shares are held indirectly in a trust for his spouse. This split between direct and indirect ownership reflects both his personal holdings and related family-trust holdings reported in the filing.

What does the tax-withholding transaction mean in the Tennant Co (TNC) Form 4?

The tax-withholding disposition shows 2,456 shares valued at $78.81 each used to pay taxes due from the option exercise. Instead of paying cash, shares are surrendered back, reducing net shares received but avoiding a separate cash outlay while not signaling an open-market sale.

Were the Tennant Co (TNC) stock options exercised by Donal Mulligan fully vested?

Yes. A footnote specifies the options were fully vested when exercised. Fully vested options are exercisable without further service requirements, so converting them into 3,538 common shares reflects the completion of this compensation component for the reporting person.
