URBASZEK MARCIN 4

What Happened

• Marcin Urbaszek, Chief Financial Officer of Blackstone Mortgage Trust (BXMT), sold 1,352 shares on June 17, 2026. The shares were disposed at $18.35 each for a total proceeds of $24,809. This was a sale (not a purchase) and appears to be a routine disposition to satisfy tax obligations rather than an investment signal.

Context

• The sale was executed under 10b5-1 trading plans to cover tax withholding from vested restricted stock — a common, prearranged mechanism that typically reflects administrative needs rather than a deliberate market-timing decision.
• For retail investors, routine insider sales to cover taxes or grant-related withholding generally carry less informational weight than opportunistic open-market purchases by insiders.
