Last week, we told you Jacksonville-based Florida Blue would be a Fortune 500 company if it was publicly traded, based on an estimate by Florida Trend magazine that it had $9.3 billion in revenue last year.
As it turns out, the health insurer’s parent company, which also is headquartered in Jacksonville, is much bigger than that.
GuideWell Mutual Holding Corp. last week sent proxy voting materials to its members, which included a link to a company fact sheet. While the fact sheet doesn’t offer full financial statements, it does say GuideWell had $19 billion in revenue and $1 billion in earnings last year.
That makes GuideWell by far the largest company based in Jacksonville.
The largest public company, CSX, ranked 260th in the Fortune 500 with $12.25 billion in revenue last year.
With $19 billion, GuideWell would rank 165th if it filed public financial statements.
Besides health insurance, GuideWell provides other services to health care companies including marketing and administrative functions.
It has more than 12,000 employees in 34 states, according to the fact sheet.
As a mutual holding company, it is owned by its members, which is why its insurance customers received proxy materials to vote on the company’s board of directors.
