NEW YORK CITY-SL Green Realty Corp. said Tuesday it had signed nonprofit managed-care provider Healthfirst to 172,000 square feet at 100 Church St., the largely vacant Downtown office property on which it foreclosed this past January and subsequently acquired. Separately, the REIT announced that subtenant Wolfe Trahan & Co. had committed to a direct lease and expansion at 420 Lexington Ave.

One of the Manhattan’s bigger leases thus far this year, the 20-year Healthfirst headquarters deal represents a little less than one third of the 575,000 square feet of vacant space at the 1.1-million-square-foot office property. In a release, Steven Durels, SL Green’s EVP and director of leasing and real property, notes that 100 Church “had been languishing for over five years” prior to the REIT’s commencement of a repositioning program. He adds that the Healthfirst deal is “a great validation” of the program.

The first fruits of that repositioning program took the form of a 20-year, 21,965-square-foot retail lease in May by the Farber Center for Radiation Oncology. The Farber Center’s first Manhattan location, it was also the first deal SL Green had signed at 100 Church since taking possession of the property.

Derek Trulson, Bill Peters and Daoud Awad from Jones Lang LaSalle represented Healthfirst in the transaction. SL Green was represented by a Newmark Knight Frank team that included Brian Waterman, James Kuhn, John Fanuzzi, Hal Stein and Lance Korman. The New York Post first reported the deal Tuesday morning, and asking rent was $40 per square foot, according to the Post.

At 420 Lexington, Wolfe Trahan expanded from a 5,695-square-foot sublease to a 10-year direct lease covering a total of 18,975 square feet. The tenant, a research boutique firm, focuses on transportation research, portfolio strategy and quantitative analysis.

Lease terms were not disclosed. Sinclair Li and Alissa Jacob of CB Richard Ellis represented Wolfe Trahan, while SL Green’s Larry Swiger and Ashley Gee provided in-house landlord representation.

On Monday evening, SL Green reported that second-quarter funds from operations dipped to $1.02 per diluted share from $1.07 in Q1 and $1.20 the year prior, due largely to transaction-related expenses. Analysts polled by Thomson Reuters had expected FFO of $1.01 per share, the Associated Press reported.

The REIT also reported a year-over-year jump in net income from $0.18 to $1.75 per diluted share. The increase stemmed from a $126.8-million gain on the May sale of a 45% interest in 1221 Ave. of the Americas to a wholly owned subsidiary of the Canada Pension Plan Investment Board.

That same month, SL Green entered an agreement to buy 125 Park Ave. for $330 million and entered into a joint venture with the CPPIB to acquire 600 Lexington Ave. for $193 million. During Q2, the company signed 461,492 square feet of Manhattan office leases. Average starting rents on the Manhattan portfolio were $40.09 per square feet, a 4.4% decline from the previously fully escalated rents on the same office space, SL Green said Monday.
