Insights

Equity compensation analyst

Director received routine restricted stock grant with modest size.

The Form 4 shows Raffaele Zagari, a director of Star Bulk Carriers Corp., receiving 7,580 common shares as restricted stock on June 12, 2026. The grant carries a zero-dollar price, indicating it is compensation rather than a market purchase.

restricted stock financial

"Represents a grant of shares of restricted stock issued pursuant to a restricted stock agreement"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.
