Virgin Media Ireland saw a revenue rise of 11.6% to €109m in the first three months of the year, when compared with the same period last year.
At the end of March the telecoms company had 1,061,600 cable and mobile subscriptions.
Virgin said the growth was underpinned by Mobile, B2B, TV3 Group, and its ongoing network expansion investment.
In December 2015 Virgin Media Ireland completed its acquisition of TV3, after Virgin’s parent company, Liberty Global bought the TV station earlier that year in an €87m deal.
Commenting on the contribution TV3 has made to the business, Finance Director Ewan Dunbar said: "Our broadcasting team in TV3 also delivered a very strong performance with a 15% year-on-year increase in channel viewership and strong growth in advertising revenue in Q1.
"These impressive results were fuelled by an exceptionally strong programme schedule including the NatWest Six Nations Rugby, Ireland’s Got Talent and extended news coverage of Storm Emma in early March."
