Caesars' results will come as little surprise to future owners Eldorado Resorts, with the casino operator knowing it will have significant improvements to make at Caesars following its $17.3bn acquisition of the company.
That transaction is expected to be completed in the first half of 2020, with Caesars' final year in its current form seeing full-year income from operations decrease 16% to $618m.
Equally, full-year net income fell $1.5bn, to a loss of $1.2bn, although non-GAAP adjusted EBITDA was up 4% to $2.41bn.
Despite the removal of its Chairman and CEO Jim Murren, MGM Resorts International achieved both far higher growth and revenue for 2019, rising 10% to $12.9bn.
However, Q4 brought low growth for both MGM (net revenue rose 4% to $3.2bn) and Caesars, which only saw revenue rise 3% to $2.17bn.
For the quarter, Caesars' income from operations did grow 77% to $177m, although net income dropped $502m, to a net loss of $304m.
Non-GAAP adjusted EBITDA rose 3% to $583m for Q4.
Caesars' share price was down from $14.06 at the opening of the market on Tuesday to $13.31 following its Q4 and FY release.
Eldorado's financial results will be released a day after Caesars'.
