April 30 (Reuters) - Norwegian Cruise Line Holdings missed first-quarter revenue and profit estimates on Wednesday, as rising concerns about tariff uncertainty have pressured demand for the cruise operator's premium sea voyages.

Shares of the company were down about 8% in premarket trading.

After benefiting from a post-pandemic surge, Norwegian Cruise has seen a slowdown in new bookings as consumers shy away from its high-end cruises and private island getaways amid looming concerns about a potential recession.

The company said it is updating full-year 2025 net yield forecast to reflect recent booking trends and changes in the macroeconomic environment.

On a constant currency basis, annual net yield is expected to increase between 2.0% and 3.0%, compared with its previous forecast of 3.0%.

The company posted quarterly revenue of $2.13 billion, compared with analysts' estimates of $2.15 billion as per data compiled by LSEG.

On an adjusted basis, the company logged adjusted profit of 7 cents per share, compared with analysts' estimates of 9 cents.
