Acrivon (ACRV) director receives 9,366 restricted stock units in equity grant

Rhea-AI Filing Summary

Acrivon Therapeutics, Inc. director Ivana Magovcevic-Liebisch received an equity award in the form of 9,366 restricted stock units of common stock. The award was granted at no cash cost to her and represents a compensation-related acquisition rather than an open-market purchase.

Each restricted stock unit gives her the right to receive one share of Acrivon common stock, but the units will vest in full only on May 18, 2027, provided she continues to serve the company through that date. Following this grant, her reported direct holding from this award is 9,366 shares, highlighting a single, time-based vesting grant rather than ongoing trading activity.

Insights

Equity compensation analyst

Director received time-based RSU grant, a routine equity compensation award.

Director Ivana Magovcevic-Liebisch was granted 9,366 restricted stock units of Acrivon Therapeutics, Inc. common stock. The grant is recorded at a price of $0.0000 per share, indicating a compensation award rather than an open-market transaction, and uses code A for grant/acquisition.

The RSUs vest in full on May 18, 2027, conditioned on continuous service, so economic value depends on both future share price and her ongoing role. There are no derivative exercises or sales reported, and post-transaction holdings shown are entirely from this grant, suggesting a standard board compensation grant rather than a signal-driven trade.

restricted stock units financial

"These shares represent restricted stock units ("RSUs"). Each RSU represents a contingent right"

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.

RSUs financial

"These shares represent restricted stock units ("RSUs"). Each RSU represents a contingent right"

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.
