Carnival Corp. (NYSE: CCL) on Thursday posted third quarter 2019 results that outpaced both revenue and earnings estimates. However, shares are down about 8% on the day after the cruise line operator trimmed its full-year outlook.

The Miami, Florida-based Company reported earnings of USD 2.63 per share, ahead of USD 2.53 expected. A year ago, Carnival delivered earnings of USD 2.36 per share.

Revenues totaled USD 6.53 during the period ended August 3, beating the average estimate of USD 6.16. In Q3 of fiscal 2018, Carnival generated USD 5.84 Billion in revenue.

During the quarter, the Company also released its 2018 Sustainability Report, detailing its progress made last year toward its 2020 sustainability goals. Next year, Carnival plans to reduce its carbon footprint by 25% compared to 2005. It is also aiming to improve water use efficiency by 5% compared to its 2010 baseline.

Carnival, the largest U.S. Cruise operator, provided an outlook for the full year, fourth quarter 2019 and 2020. For the full year, the Company expects adjusted earnings per share to be in the range of USD 4.23 to USD 4.27, reflecting recent fuel price increases, compared to June guidance of USD 4.25 to USD 4.35. Full-year 2019 results are also likely to be impacted by Hurricane Dorian and tensions in the Arabian Gulf, the Company said.

For the fourth quarter of fiscal 2019, Carnival expects fourth-quarter fiscal 2019 EPS to be in the range of USD 0.46 to USD 0.50 compared with adjusted earnings of USD 0.70 per share reported in the prior-year quarter. The Company said its new forecast reflects disruptions due to weather and the U.S. government’s policy change on travel to Cuba.

For fiscal 2020, Carnival expects capacity growth to be nearly 7%.

Separately, Carnival said on Thursday it will pledge a total of USD 33 Million to St. Jude’s Children’s Research Hospital by 2024. The Company has raised more than USD 18 Million in support of St. Jude since 2010.
