A loan backing Pittsburgh’s U.S. Steel Tower has been transferred to special servicing ahead of its June maturity, even while the property continues to generate steady cash flow, as major tenant lease expirations loom.
The tower, a signature piece of the Pittsburgh skyline, has been in New York-based landlord 601W Companies’ hands since 2011. The investment firm refinanced the 2.3-million-square-foot property with a $245 million loan in 2021 at a rate just under 3.7 percent, according to Morningstar Credit. The borrower was late on its interest-only payments four times beginning in April 2025, but was current as of March.
Yet, the loan, which includes $160 million of securitized debt, $40 million in unsecuritized subordinate debt and $45 million in mezzanine debt, is set to mature in June. The servicer commentary points to a growing concern about the borrower’s ability to to refinance in the current lending environment. The transfer to special servicing reflects elevated default risk if the loan cannot be extended or reworked, according to Morningstar Credit.
The building also faces looming tenant decisions. The leases for the tower’s two main tenants — the University of Pittsburgh Medical Center and namesake U.S. Steel — are set to expire within the next two years. With office values under pressure, particularly in mid-sized cities like Pittsburgh, a new appraisal could fall short of the tower’s $381.5 million valuation it received in 2021, making refinancing more difficult and likely more expensive.
“This tenant risk, coupled with $40 million of unsecuritized subordinate debt and $45 million of mezzanine debt, made this transfer fairly predictable in the current lending environment,” according to Morningstar Credit.
Representatives from 601W Companies, as well as the special servicer Greystone did not return The Real Deal’s requests for comment.
The transfer to special servicing does not necessarily signal immediate distress. The property continues to generate steady cash flow and remains largely leased, suggesting the move is aimed at negotiating a modification, extension or other resolution ahead of maturity.
The U.S. Steel Tower situation is the latest sign of strain for 601W Companies. In Chicago, the firm’s Aon Center loan of $536 million returned to special servicing this month after allegedly missing a required payment for tenant improvements and leasing commissions. Still, 601W has remained active in commercial real estate, purchasing a 1.4 million-square-foot building in Chicago from Brookfield Properties for a heavily discounted $41 million in February, just days before the Pittsburgh tower went into special servicing.
