Summary

Jack in the Box extended its cooperation agreement with activist investor GreenWood Investors through the 2028 annual meeting nomination window. The amendment keeps standstill, voting, and other provisions in place, caps the board at nine directors without GreenWood's consent, and commits the company to hold an investor event by June 30, 2027 with GreenWood consultation on scheduling and agenda.

GreenWood will also receive advance copies of investor materials and the company will consider its comments in good faith, though GreenWood has no approval rights. In connection with the agreement, the board appointed Rachel Ruggeri, former Starbucks CFO, as an independent director effective September 17, 2026.

Director Michael Murphy will retire at the 2027 annual meeting and will not stand for reelection; the filing states his decision is not due to any disagreement with the company. The company also reiterated that President Taylor Montgomery is expected to become CEO within the next 12 months and join the board at that time. For retail holders, the extension signals continued alignment with GreenWood and a commitment to board refreshment and investor engagement. The board size cap and investor event commitment give GreenWood ongoing influence over governance and communication, while the appointment of a seasoned restaurant-industry finance executive adds relevant expertise.
