Phoenix-based Banner Health saw its net income climb from $44 million in 2018 to $726.8 million in 2019 due to strong investment gains, according to recently released financial documents.
"Investment returns were robust in 2019, resulting in $641.1 million of realized and unrealized gains," Banner Health reported.
The health system's total revenue climbed to $9.4 million in 2019, up 10.6 percent from the $8.5 million posted in 2018.
The revenue growth was attributed to a 7 percent growth in care delivery revenue and a 29 percent increase in revenue from its insurance division.
Expenses also rose year over year. In 2019, Banner reported $9.2 billion in expenses; in 2018, it recorded $8.3 billion in expenses.
