Norwegian Cruise Line posted better earnings for the fourth quarter on higher revenue while producing results above Wall Street consensus.

The Frank Del Rio-led company reported adjusted net income of $156.8m versus earnings of $127.7m a year earlier.

Those results translated into EPS of $0.68, an improvement over year-ago results of $0.56 that bested analysts' estimate of $0.64.

Net income was $98.8m, or $0.43 EPS, versus earnings of $72.2m, or $0.32, a year ago.

Adjusted net revenue gained 13% to $970m while evenue increased 11% to $1.2bn, primarily due to Norwegian Joy joining the fleet and strong organic pricing across core markets.

"The strong, record performance we delivered in 2017 was the perfect end to a historic year as we celebrate the five-year anniversary of our public offering," Del Rio said.

"Our solid ... performance will continue in 2018, having entered the year in the best booked position in our company's history," he added.

For the full year, adjusted net income was $908m, or $3.96 EPS, up from earnings of $776.3m, or $3.41 EPS, during 2016.

Revenue gained 10.7% to $5.4bn.

Looking forward, the company expects EPS of about $0.52 for the first quarter of 2018 and $4.45 to $4.65 for the year.

UBS analyst Robin Farley noted to clients that about half of the consensus beat of $0.05 was due to a one-time tax benefit of $7.5m, or $0.03 EPS, following the new tax law.
