Moody's Investors Service has affirmed the "A1" and "A1/VMIG 1" ratings on Houston-based Memorial Hermann Health System's bonds, affecting $1 billion of outstanding debt.
Moody's has also revised the system's outlook to positive from stable.
The "A1" rating affirmation is based on several factors, including Memorial Hermann's status as a large health system with favorable demographics and a leading market position in the Houston area. The "A1/VMIG 1" rating affirmation is based on the system's self-liquidity support of variable rate bonds.
The outlook revision reflects Moody's expectation that Memorial Hermann will maintain strong operating margins and liquidity.
