The nation’s largest hospital landlord is blaming most of its fourth-quarter financial losses on Steward Health Care, the company that operates thirty-three hospitals in eight states, including Trumbull Regional, Sharon Regional, and Hillside Memorial hospitals here in the Valley.

In a Securities and Exchange filing released on Wednesday, Medical Properties Trust reported growing losses in the most recent quarter of $664 million, mostly due to $772 million in write-offs and other charges that the company says are linked to its largest tenant, Steward Health.

Medical Properties has already loaned $20 million to Steward, with another $17 million planned from another lender, as Steward works to avoid bankruptcy. In addition, MPT has deferred full rent collections from Steward until the end of June.

MPT says the resumption of full rent payments by Steward will be attained by several strategic moves, including the sale of some assets, the identities of which have not been publicly disclosed. Steward has been making partial rent payments to Medical Properties.

In January, MPT revealed that Steward owed $50 million in unpaid rent for properties around the country.

Two lawsuits pending in Trumbull County allege that Steward Health has failed to pay for nearly $130,000 worth of goods and services at Trumbull Regional Hospital.

In one suit, Niles-based Penn Care Inc. is seeking $67,940.18 for the cost of goods and services they say they've provided but not been paid for since October of 2021.

Penn Care provides EMS supplies, ambulance sales, EKG monitors, and disaster response equipment.

Another lawsuit filed by Niles-based electrical contractor, Becdel Controls, Inc. accuses Steward Health and MPT of Warren Steward, LLC of failing to pay for $61,674.31 in electrical work done at Trumbull Regional Hospital.

Recently, a $3,400 plus interest judgment against Steward issued in August by Girard Municipal Court to contractor Boak & Sons, was transferred to Trumbull County Common Pleas Court.

A recent memo from Steward Health Care Executive President Michael Callum sent to employees in Massachusetts stated that “Steward has agreed upon the principal terms for a significant financial transaction to help stabilize our company.”
