Restricted Stock Units financial

"vesting of Restricted Stock Units granted to the reporting person on August 8, 2025"

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.

Rule 10b5-1 regulatory

"The filing’s Rule 10b5-1 checkbox is not marked as being pursuant"

Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.

FAQ

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

What insider transaction did EnerSys (ENS) report for Keith D. Fisher?

EnerSys reported that Keith D. Fisher had 573 shares of common stock withheld or forfeited on August 8, 2026 to satisfy payment of exercise price or tax liability related to vesting Restricted Stock Units granted on August 8, 2025.

How many EnerSys (ENS) shares does Keith D. Fisher hold after this Form 4 transaction?

After the reported transaction, Keith D. Fisher directly holds 22,122 shares of EnerSys common stock. The 573 shares were withheld or forfeited in connection with RSU vesting, so they did not represent an open-market sale and were used to satisfy related obligations.

Was the EnerSys (ENS) Form 4 transaction by Keith D. Fisher an open-market sale?

No. The Form 4 describes an F-code transaction, meaning 573 shares were delivered or withheld for payment of exercise price or tax liability tied to RSU vesting, rather than an ordinary open-market sale initiated by the insider.

What does the footnote on Keith D. Fisher’s EnerSys (ENS) Form 4 explain?

The footnote explains that the 573 shares were forfeited in connection with the vesting of Restricted Stock Units granted to Keith D. Fisher on August 8, 2025, clarifying that the disposition arose from an equity award vesting event.

Was Keith D. Fisher’s EnerSys (ENS) Form 4 transaction under a Rule 10b5-1 trading plan?

The filing’s Rule 10b5-1 checkbox is not marked as being pursuant to such a plan, and the footnote only ties the 573-share disposition to RSU vesting, so this event appears as a compensation-related withholding rather than a pre-planned trading program sale.
