Five9, Inc. is changing how its corporate governance works. On May 20, 2026, stockholders approved an Amended and Restated Certificate of Incorporationdeclassification of the Board of Directors, moving away from a staggered board where directors serve multi‑year, overlapping terms.
The charter also eliminates supermajority voting requirements, so future stockholder approvals covered by these changes will generally require only standard voting thresholds rather than very high approval levels. On May 26, 2026, the Board approved updated Amended and Restated Bylaws to align the bylaws with the new, non‑classified board structure. The full texts of the charter and bylaws are attached as Exhibits 3.1 and 3.2.
