Item 5.02.			Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On September 19, 2025, Empire State Realty Trust, Inc. (the “Company”) entered into a transition agreement (the “Transition Agreement”) pursuant to which Thomas P. Durels, Executive Vice President, Real Estate, has begun the transition of his duties to two new Co-Heads of Real Estate: (i) Ryan Kass, Chief Revenue Officer of Real Estate and Director of Leasing, and (ii) Jackie Renton, Chief Operating Officer of Real Estate. Mr. Kass and Ms. Renton will each report to the Company’s President, Christina Chiu, and the Company’s Chairman & CEO, Anthony E. Malkin. Mr. Kass has been with the Company since 2013 and previously served as Director of Leasing. Ms. Renton joined the Company in September from Atlas Capital Group, a private real estate investment, development and management firm, where she previously served as Chief Operating Officer.

Under the Transition Agreement, Mr. Durels will remain an executive officer of the Company through June 30, 2026 (the “Transition Date”) and will serve as a consultant to the Company through June 30, 2027 (the “Termination Date”), unless his employment is earlier terminated in accordance with the Transition Agreement. During this period, Mr. Durels will be entitled to receive (i) a base salary in the amount of $757,050 per annum and (ii) continued vesting of his outstanding Company equity awards. In addition, Mr. Durels will remain eligible to earn a bonus for 2025 with payout determined based on the performance conditions of the previously approved 2025 executive compensation plan.

Unless he is terminated for “cause” (as defined in the Transition Agreement) or resigns without the agreement of the Company prior to June 30, 2027, Mr. Durels will also be entitled to receive the following separation payments: (a) a cash bonus for 2026 with opportunity aligned with his 2025 award and payout determined based on the performance conditions of the 2026 executive compensation plan; (b) a cash bonus for 2027 of $283,894; (c) an equity award of $1,396,050 (to be granted in March 2026) to vest 100% on the Termination Date; (d) an equity award of $698,025 to be granted with immediate vest provisions on the Termination Date; (e) accelerated vesting of his outstanding equity awards as of the Termination Date, with the performance-based equity awards vesting in accordance with applicable award agreements; and (f) any unpaid base salary through June 30, 2027 (if terminated earlier than such date).

The payments and benefits described above are subject to Mr. Durels’ non-revocation of a general release of claims in favor of the Company and continued compliance with the terms of the Transition Agreement, including customary restrictive covenants.

The foregoing general description of the Transition Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Transition Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated by reference herein.
