Irish Ferries operator ICG has reported revenue of €308.8m in the first ten months of 2019, an increase of 8.2pc on the same period last year.
ICG said a "significant" proportion of the improvement came from the ferries division, on the back of improved scheduling reliability following major disruptions in 2018.
Despite this, it experienced "some volatility in carryings as key Brexit dates were approached and subsequently postponed".
The overall effect of this continuing uncertainty "is generating negative impact on consumer sentiment and trade flows as investment decisions are delayed".
In the ferries arm of the company total revenues recorded in the period to 31 October amounted to €184.3m, a 7pc increase on the prior year, according to a trading update.

The company's fuel costs are marginally higher this year over 2018.
Shares in ICG were trading up less than 1pc yesterday at €4.56.
