S&P Global Ratings revised Royal Oak, Mich.-based Beaumont Health's outlook to positive from stable.
"The positive outlook reflects our anticipation that Beaumont Health will maintain current operating margins due to its excellent market position and post-merger success, and in addition, will continue to gradually build upon unrestricted reserve levels thereby improving key balance sheet metrics such that they are more commensurate with a higher rating," said S&P analyst Kevin Holloran.
The rating agency also affirmed the "A" rating on Beaumont Health's $1.2 billion of various revenue bonds.
