**FOR IMMEDIATE RELEASE**

February 23, 2026

**SEAPORT ENTERTAINMENT GROUP ANNOUNCES LEASE WITH BALLOON MUSEUM TO TRANSFORM HISTORIC TIN BUILDING INTO A NEW CULTURAL DESTINATION**

*The internationally recognized interactive contemporary art experience* 

*will open its U.S. flagship in the Seaport neighborhood, and the Tin Building by Jean-Georges has closed to begin preparations for the Balloon Museum.*

**NEW YORK, NY** – Seaport Entertainment Group Inc. (NYSE: SEG) ("Seaport Entertainment Group" or "SEG") and Lux Entertainment today announced that Balloon Museum, the award-winning contemporary art format, will open at the Tin Building in Summer 2026. The Tin Building will serve as the Balloon Museum's U.S. flagship, enriching the cultural landscape in the Seaport neighborhood by offering a community-oriented, experiential art destination designed to attract visitors of all ages.

The current food and beverage operations at the Tin Building will close immediately to begin preparations for the Balloon Museum.

Balloon Museum has redefined the way millions of people experience contemporary art through large-scale interactive exhibitions that transcend traditional boundaries of gallery spaces. Visitors are immersed within the artwork itself—not as passive observers, but as active participants who touch, move through, and directly engage with the installations.

"We are thrilled to bring Balloon Museum and its category-defining contemporary art exhibitions to the Seaport," said **Matt Partridge, President and Chief Executive Officer of Seaport Entertainment Group**. "Balloon Museum is a true global phenomenon that offers visitors of all ages a one-of-a-kind experience. We look forward to this exciting addition to the Seaport's existing portfolio of cultural experiences and other offerings, allowing our growing residential community and visitors to interact with art in an entirely new way."

Balloon Museum exhibitions are developed by a curatorial team that selects some of the most important contemporary creators of our time, artists whose works are featured in prestigious institutions such as MoMA, Tate, and Centre Pompidou. The unifying medium of these experiences is air—conceived as an ephemeral, democratic, and poetic element. Expanded to monumental scale, it becomes matter, metaphor, and method. Visitors float, move, or simply breathe in dialogue with works that use light, sound, and motion to create a powerful emotional landscape. Balloon Museum aims to become an

------

integral part of the neighborhood's community, a place where people of all ages not only experience art but actively participate in a shared public culture.

"The opening of our U.S. flagship in New York City marks a decisive milestone in the history of Balloon Museum," said **Roberto Fantauzzi, CEO and Founder of Lux Entertainment.** "After years of international growth, choosing New York City and an iconic location such as the Tin Building represents an even greater cultural responsibility for our team. For this new location, we will present a completely original exhibition featuring newly commissioned works by internationally renowned artists. The Balloon Museum at the Tin Building is a natural evolution and significant leap in scale, not simply a new chapter, but the beginning of a stable and ambitious new dimension for our company."

The transaction was originated by Michael Ginsberg and Jonah Larrama of OMG Variety LLC, a New York-based advisory firm specializing in creative real estate strategy, experiential partnerships and mixed-use cultural development.

Additional details about Balloon Museum's concept for New York City and additional details about potential relocations of existing Tin Building concepts will be announced in the coming months.

**SEAPORT ENTERTAINMENT GROUP AND JEAN-GEORGES RESTAURANTS <br>ADDRESS CLOSURE OF THE TIN BUILDING AND REAFFIRM PARTNERSHIP**

Seaport Entertainment Group Inc. (NYSE: SEG) ("Seaport Entertainment Group," or "SEG") and Jean-Georges Restaurants today announced that the Tin Building by Jean-Georges will close its operations effective February 23, 2026. SEG and Jean-Georges Restaurants will continue their longstanding partnership and are actively exploring opportunities to bring several popular Tin Building concepts and offerings to new spaces, both in the Seaport and across New York City.

"Re-establishing the historic Tin Building was an extraordinary opportunity to celebrate food, community, and New York's rich culinary traditions in one of the city's most iconic settings," said **Jean-Georges Vongerichten.** "I'm proud of what our team accomplished in this special place, and excited to continue our partnership with Seaport Entertainment Group as we explore new ideas in the Seaport and beyond."

Seaport Entertainment Group will continue to maintain its 25% ownership of Jean-Georges Restaurants, and the closure of the Tin Building does not change Jean-Georges' commitment to the Seaport neighborhood. Together, they plan to continue developing the Seaport and New York City's culinary landscape.
