SeaWorld Entertainment (SEAS) - Get Report posted a first-quarter loss of 44 cents a share, narrower than the year-earlier loss of 73 cents a share and Wall Street expectations for a loss of 63 cents.

Revenue in the quarter rose 1.6% to $220.6 million, higher than a year earlier and ahead of forecasts of $215.9 million.

SeaWorld said attendance in the first quarter at its parks rose 3.6% to 3.3 million, slightly above forecasts.

"Attendance and revenue primarily benefited from increased demand and increased in-park spending which was partially offset by impacts from unfavorable weather in some of our parks and the shift in the timing of Easter and school spring break in some of our markets from the first quarter to the second quarter," said CEO Gus Antorcha in a statement Tuesday.

The company said admission per capita in the quarter fell 4.3% to $38.60, below estimates of $39.30.

The stock was flat in premarket trading at $26.36.
