Context These grants follow Mr. Gibson’s election to the board on March 3, 2026, and represent typical director compensation rather than a market buy or sell. Awards at $0.00 reflect issuance terms, not market value; actual economic value depends on PACB’s share price as the awards vest. For retail investors, such grants signal alignment of the director’s interests with shareholders but do not by themselves indicate a personal market view.
