Gartner director granted 1,489 RSUs

Bisson Peter reported acquisition or exercise transactions in this Form 4 filing.

Rhea-AI Filing Summary

Bisson Peter reported acquisition or exercise transactions in this Form 4 filing.

Gartner Inc. director Peter Bisson received a grant of 1,489 restricted stock units (RSUs), each representing one share of Gartner common stock. The RSUs were awarded at no cash cost and increase his directly owned equity-based compensation by 1,489 units.

According to the terms, 100% of these RSUs are scheduled to vest on May 28, 2027, provided he continues serving as a director through that date. Until vesting, the units are not delivered as common shares, so this filing mainly reflects routine, service-based director compensation rather than an open‑market stock purchase or sale.

Restricted Stock Units financial

"security_title: "Restricted Stock Units" and footnote describing RSUs vesting"

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.

grant/award acquisition financial

"transaction_action: "grant/award acquisition" for the RSU transaction"

vesting financial

"One hundred percent (100%) of the RSUs shall vest on May 28, 2027"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

director financial

"subject to the Grantee's continued service as a director through such date"

What insider transaction did Gartner (IT) director Peter Bisson report?

How many Gartner (IT) restricted stock units did Peter Bisson receive?

He received 1,489 restricted stock units linked to Gartner common stock. This increases his equity-based holdings by 1,489 units, contingent on future vesting, and reflects a compensation-related award instead of an open-market trading decision involving Gartner shares.

When do Peter Bisson’s Gartner (IT) RSUs vest?

All 1,489 RSUs are scheduled to vest on May 28, 2027. Vesting requires his continued service as a director through that date, meaning the units convert into common shares only if that service condition is fully satisfied.

Is Peter Bisson’s Gartner (IT) Form 4 transaction a stock purchase or sale?

How many Gartner (IT) shares does the RSU grant represent for Peter Bisson?

The RSU grant covers 1,489 underlying shares of Gartner common stock. Each restricted stock unit corresponds to one share that may be delivered upon vesting, assuming the director continues in service through the specified vesting date.
