MAIER PAUL V 4

What Happened

Paul V. Maier, a director of International Stem Cell Corp (ticker: ISCO), received two equity awards on 2026-06-11 covering a total of 212,584 shares (30,000 and 182,584).

These are awards (not open-market purchases or sales) that vest over time rather than immediate stock purchases.

Context

These awards are time-based equity grants (derivative instruments) that vest over the coming year; they do not represent an immediate sale or cash out. For retail investors, such grants are routine executive/board compensation and should be interpreted as compensation-related, not a direct market buy signal. The late filing may reduce transparency for a short period; it does not change the economic terms of the awards.
