Rhea-AI Filing Summary

Acrivon Therapeutics director Derek DiRocco received a grant of 9,366 restricted stock units (RSUs) of Common Stock. The award was made as a grant or other acquisition at a price of $0.00 per share, leaving 9,366 shares reported as held after the transaction.

Each RSU represents a contingent right to receive one share of Acrivon Therapeutics, Inc. Common Stock and will vest in full on May 18, 2027, subject to continuous service through that date. Under DiRocco’s arrangement with RA Capital Management, L.P., he holds the RSUs for the benefit of RA Capital Healthcare Fund, L.P. and RA Capital Nexus Fund II, L.P., must turn over any stock received upon settlement to RA Capital Management, and therefore disclaims beneficial ownership of these RSUs and the underlying common stock.

restricted stock units ("RSUs") financial
"These shares represent restricted stock units ("RSUs"). Each RSU represents a contingent right to receive one share"
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
beneficial ownership financial
"The Reporting Person therefore disclaims beneficial ownership of the RSUs and underlying common stock."
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
advisory fees financial
"which will offset advisory fees owed by the Fund and the Nexus Fund II to the Adviser."
Advisory fees are payments made to financial advisors or investment managers for guidance, portfolio management, or other services, typically charged as a fixed amount or a percentage of assets under management. They matter because they lower an investor’s net returns—like paying a mechanic to tune a car, you expect better performance, so investors weigh whether the cost is justified by higher returns, better risk control, or convenience.
continuous service financial
