Boundless Bio Director Nancy Whiting Granted 32,000 Stock Options at $1.40 Exercise Price

Nancy Whiting, a director of Boundless Bio, Inc. (BOLD), was granted 32,000 stock options on June 15, 2026. The options have an exercise price of $1.40 per share and expire on June 14, 2036. The options vest in equal monthly installments over 12 months following June 15, 2026, with an acceleration provision: if the next annual stockholders meeting occurs before June 15, 2027, any remaining unvested options will vest on that meeting date. Vesting is contingent on Whiting's continued service on the board of directors through the vesting dates. The transaction was reported on Form 4 and was signed by Jessica Oien as attorney-in-fact for Nancy Whiting. This represents a standard equity compensation grant to a board member, with the zero-dollar transaction price indicating a grant rather than a purchase.
