Moody's Investors Service affirmed its "A3" rating on San Francisco-based Dignity Health, affecting $5.3 billion of debt.
The affirmation is a result of several factors, including Dignity's large size, strong market share and ongoing strategy to expand care delivery. Moody's unfavorably viewed the health system's weakening payer mix and debt measures that are lower than similarly rated peers.
The outlook is stable, reflecting the health system's improved operations through nine months of fiscal year 2018, which ended March 31.
