Six Flags Entertainment Corporation (FUN) entered into a Cooperation Agreement with Sachem Head Capital Management, expanding its Board from 12 to 13 directors and appointing Jonathan Brudnick as a Class III director with a term expiring at the 2027 Annual Meeting. He also joins the Nominating and Governance Committee.

Mr. Brudnick delivered an irrevocable resignation letter effective upon the earliest of Sachem Head falling below a 3% beneficial ownership/economic exposure threshold or a final non‑appealable judgment finding an uncured material breach of the agreement. Until the standstill termination date, Sachem Head agreed to vote in line with the Board’s recommendations, with a carve‑out allowing proportional voting if ISS or Glass Lewis recommend otherwise on Company proposals (excluding director elections) and full discretion on extraordinary transactions. The agreement includes customary standstill and mutual non‑disparagement provisions and remains in place until 20 days after Mr. Brudnick ceases to serve.

The Company noted the Board will expand to 13 and, following previously announced departures, decrease to 11. A related press release was furnished as an exhibit.

Six Flags Entertainment Corporation (FUN) ha stipulato un Accordo di Cooperazione con Sachem Head Capital Management, espandendo il Consiglio da 12 a 13 membri e nominando Jonathan Brudnick come direttore di Classe III con un mandato che scadrà all'Assemblea Annuale del 2027. Si unisce anche al Comitato di Nomina e Governance.

Il signor Brudnick ha presentato una lettera di dimissioni irrevocabile efficace al verificarsi della prima delle seguenti condizioni: Sachem Head scenda al di sotto di una soglia del 3% di proprietà beneficiaria/esposizione economica o venga emessa una sentenza finale non appellabile che determini una violazione materiale non sanata dell'accordo. Fino alla data di terminazione dello standstill, Sachem Head si è impegnata a votare in linea con le raccomandazioni del Consiglio, con un'eccezione che consente voto proporzionale se ISS o Glass Lewis raccomandano diversamente sulle proposte della Società (escluse le elezioni dei membri del consiglio) e piena discrezione sulle operazioni straordinarie. L'accordo comprende disposizioni di standstill e di non diffamazione reciproca e resta in vigore fino a 20 giorni dopo che il sig. Brudnick cesserà di prestare servizio.

La Società ha osservato che il Consiglio passerà da 12 a 13 membri e, a seguito delle dimissioni già annunciate, passerà a 11. È stato fornito un relativo comunicato stampa come allegato.

Hasta la fecha de terminación del standstill, Sachem Head acordó votar de acuerdo con las recomendaciones de la Junta, con una excepción que permite votación proporcional si ISS o Glass Lewis recomiendan lo contrario en las propuestas de la Compañía (excluidas las elecciones de directores) y total discreción en operaciones extraordinarias. El acuerdo incluye disposiciones habituales de standstill y de no menoscabo mutuo y permanece vigente hasta 20 días después de que el Sr. Brudnick deje de prestar servicio.

Six Flags Entertainment Corporation (FUN)은 Sachem Head Capital Management와 협력 계약을 체결하여 이사회 수를 12명에서 13명으로 확장하고 Jonathan Brudnick를 3학년 이사로 임명했으며 임기는 2027년 연차주주총회에서 만료됩니다. 또한 그는 선임 및 거버넌스 위원회에 합류합니다.

브루드닉 씨는 Sachem Head가 유익 소유권/경제적 노출 임계치를 3% 아래로 떨어뜨리거나 수정되지 않은 중대한 위반을 인정하는 최종적이고 불가항력적인 판결이 내려지는 최초의 시점에서 효력이 발생하는 취소 불가 사임서를 제출했습니다. Standstill 종료일까지 Sachem Head는 이사회 권고에 따라 표결하기로 합의했으며, 회사 제안에 대해 ISS나 Glass Lewis가 다르게 권고하는 경우에는 비례 의결을 허용하고, 특별 거래에 대해선 전적인 재량권을 갖습니다. 이 계약에는 일반적인 Standstill 및 상호 비난 금지 조항이 포함되어 있으며 Brudnick 씨가 재직을 중단한 날로부터 20일 후까지 유효합니다.

회사는 이사회가 13명으로 확대되고, 이미 발표된 이직으로 인해 11명으로 감소할 것이라고 밝혔습니다. 관련 보도자료가 첨부로 제공되었습니다.

Insights

Board expands; activist cooperation sets voting, standstill, and a 3% trigger.

The agreement between Six Flags and Sachem Head adds an independent director and sets defined governance terms. Mr. Brudnick’s Class III term runs through the 2027 Annual Meeting and includes committee service. The Board temporarily increases to 13, then is expected to decrease to 11 after prior departures.

Key mechanics include a 3% Minimum Ownership Requirement tied to Mr. Brudnick’s resignation letter, a standstill, and mutual non‑disparagement. Voting commitments align Sachem Head with Board recommendations, with a proportional voting carve‑out if ISS or Glass Lewis recommend against Company proposals (other than director elections) and discretion on extraordinary transactions.

Actual effects depend on future holder decisions and any changes in ownership. The agreement lasts until 20 days after Mr. Brudnick leaves the Board, anchoring the timeframe for these commitments.

If prior to the Standstill Termination Date (as defined below) Mr. Brudnick resigns from the Board or is rendered unable to or refuses to serve on the Board for any reason, and Sachem Head beneficially owns shares of common stock (“Common Stock”) at in the aggregate at least equal to the Minimum Ownership Requirement (as defined below), Sachem Head has the right to propose a candidate for replacement that is reasonably acceptable to the Board.
