tax-withholding disposition financial

"Represents shares withheld to cover taxes due by the reporting person upon vesting of certain restricted security awards."

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.

restricted securities financial

"Consists of unvested restricted securities granted to the reporting person on June 9, 2026."

Restricted securities are shares or other investment instruments that come with legal or contractual limits on when and how they can be sold, like stock given to founders or bought in a private offering. Think of them as assets in a locked box that can’t be freely traded until certain conditions — such as a waiting period, company registration, or specific approvals — are met. For investors this matters because restricted securities are less liquid and can affect timing, price, and perceived value when they eventually enter the market.

Equity Incentive Plan financial

"Granted pursuant to the Sensata Technologies Holding plc 2021 Equity Incentive Plan."

An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.

grant, award, or other acquisition financial

"Grant, award, or other acquisition"

ordinary shares financial

"Ordinary Shares, par value EUR 0.01 per share"

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What insider transactions did Martha N. Sullivan report at Sensata Technologies (ST)?

Martha N. Sullivan reported receiving 3,827 ordinary shares as a restricted securities grant and a related withholding of 508 shares for taxes. Both transactions involved ordinary shares of Sensata Technologies Holding plc and reflect routine equity compensation activity, not open-market trading.

How many Sensata (ST) shares did Martha N. Sullivan receive in the latest award?

She received 3,827 ordinary shares as a grant with a zero purchase price. The award was made under the Sensata Technologies Holding plc 2021 Equity Incentive Plan and consists of unvested restricted securities that are scheduled to vest in full at the 2027 Annual Shareholders Meeting.

When do Martha N. Sullivan’s newly granted Sensata (ST) restricted shares vest?

The unvested restricted securities granted on June 9, 2026 vest 100% on the date of the 2027 Annual Shareholders Meeting. Until that vesting date, they remain restricted, meaning they are subject to the plan’s conditions and are not fully available like regular outstanding shares.

Why were 508 Sensata (ST) shares withheld from Martha N. Sullivan?

The 508 shares represent withholding to cover taxes due upon vesting of certain restricted security awards. Instead of paying cash for the tax liability, a portion of the vested shares was retained, a common mechanism that does not involve an open-market stock sale.

How many Sensata (ST) shares does Martha N. Sullivan hold after these transactions?

Following the June 9, 2026 transactions, Martha N. Sullivan directly holds 373,717 ordinary shares of Sensata Technologies Holding plc. This figure reflects the net result after the 3,827-share grant and the 508-share tax withholding disposition reported in the same Form 4 filing.

Were Martha N. Sullivan’s recent Sensata (ST) transactions open-market buys or sells?

No, the transactions were not open-market trades. One entry is a grant or award acquisition of 3,827 shares at no cost, and the other is a tax-withholding disposition of 508 shares used to satisfy tax obligations on vesting of restricted awards, rather than a discretionary market sale.
