Sphere Entertainment Co. recently announced the resignation of Gregory Brunner, its senior vice president, controller and principal accounting officer, effective Oct. 17. The company, valued at $2.3 billion with shares currently trading at $65, stressed in a Securities and Exchange Commission filing that Brunner’s departure is not related to any disputes over accounting practices or internal controls. Robert Langer, the company’s executive vp, chief financial officer and treasurer, will serve as interim principal accounting officer until Brunner’s replacement can be found.
Brunner, who joined Sphere in June of 2023 after nearly 18 years at accounting giant KPMG, brought extensive experience in global audits and financial strategy, and has been active in nonprofit work, having served on the NYC executive leadership team of the American Heart Association. He has not signaled his next move.
Brunner’s exit comes amid Sphere’s efforts to stabilize performance following mixed 2025 earnings. Q2 revenue rose 3.4% year-over-year to $282.7 million, exceeding expectations and reversing a Q1 decline. Sphere’s venue operations saw a 16% revenue increase, while MSG Networks dropped 12%.
A major contributor to recent momentum is Sphere’s signature immersive events, including concert residencies by The Backstreet Boys and Eagles, but particularly its ongoing production of The Wizard of Oz. This reimagined experience transforms the 1939 classic into a 4D spectacle using Sphere’s 160,000 sq. ft. 16K-resolution wraparound screen, 167,000 programmable speakers and multi-sensory effects including wind arrays, fog, fire bursts, bubbles and something called haptic seating. The original score has been re-recorded for enhanced clarity, and AI has been used to expand scenes and create dynamic visuals. As of mid-September, Sphere had sold more than 500,000 tickets for The Wizard of Oz, generating over $65 million in sales.
