ATCO Locks Down 2 Lease Renewals at Midtown Office

ATCO Properties & Management has sealed two renewals at 555 Fifth Ave. as existing tenants Telsey Advisory Group (TAG) and Maritime Capital LLC committed to the 257,000-square-foot property in the heart of Midtown. Both firms have been part of the building’s tenant roster since 2017, according to the landlord.
TAG — a leading equity research, trade execution, investment banking and consulting firm — will continue to occupy roughly ​​6,830 square feet on the property’s seventh floor. Maritime Capital — an investment management services firm that offers financial planning, consulting and investment advisory services — has a slightly smaller footprint within the property, occupying 6,031 square feet on the ninth floor.
“When strong tenants such as Telsey Advisory Group and Maritime Capital reaffirm their commitment to our building, it’s a testament to our dedication to providing exceptional spaces and services,” said Kate Hemmerdinger Goodman, co-president, ATCO Properties & Management. “With a prime Midtown location, we are thrilled that 555 Fifth Avenue meets both of their needs, and we look forward to many more years of partnership and growth together.”
Hemmerdinger Goodman brokered the deal in-house on behalf of ATCO. No brokers were involved in negotiations on the tenants’ sides.
While information regarding the length of these renewals remains undisclosed, the landlord has revealed that the asking rent price in the building was around $63 per square foot.
Occupying the southeast corner of East 46th Street, 555 Fifth Ave. offers a coveted mix of commercial space just steps from Grand Central Terminal. The 20-story building is also within walking distance of Bryant Park, the New York Public Library, Rockefeller Center and the heart of Fifth Avenue shopping. Constructed in 1955, it offers modern amenities, including green terraces, energy-efficient design, upgraded elevators and an intelligent HVAC system.
The building’s tenant roster includes the likes of law firm Nicoletti Spinner Ryan Gulino Pinter — which recently renewed its lease for a 12,497-square-foot space on the eighth floor — as well as jewelry companies like Kiran Gems and Andrew Fabrikant & Sons, all of which signed deals in November 2023.
