Casino resort operators such as Wynn have been earning record profits from a steady post-pandemic recovery and travel rebound in Macau.
Shares of the company rose 2.9% in extended trading.
After over a month of negotiations last year, Wynn ratified a five-year contract with Las Vegas hospitality unions to increase wages for employees.
Company's board also announced a dividend of 25 cents per share.
Wynn Resorts posted adjusted profit of $1.91 per share, ahead of analyst estimates of $1.15, according to LSEG data.
Its operating revenues during the fourth quarter were $1.84 billion, while analysts expected $1.74 billion.
