CVS is buying health insurance giant Aetna, the companies announced Sunday.
If approved, the $69 billion acquisition -- $77 billion including debt -- would drastically remap the health care industry. CVS Health is a massive drugstore chain and prescription drug insurer, while Aetna is one of the nation's largest health insurers.
It would also go down as the largest health insurance deal in history, far exceeding Express Scripts' $29 billion acquisition of Medco in 2012, the last record-holder. Ref. CNN.
