Three Ireland grows customer base to 5.6 million and remains Ireland’s largest mobile telecommunications provider.
Three Ireland has reported that it grew its total customer base by 6% year-on-year to 5.6 million in the first half of 2026, while total revenue increased by 2% to €314 million.
It also published stronger profitability figures for the six months, with EBITDA increasing by 5% to €88 million, while underlying earnings before interest and tax (EBIT) increased by 13% to €18 million.
This was supported by lower operating expenses and continued cost discipline according to Three.
The country’s largest mobile telecommunications provider said its contract customers increased by 8% year-on-year to 4.7 million, which it attributed to continued demand for Three’s services across consumer and business segments.
Customer growth was supported by the continued expansion of Three’s network, with 5G coverage now reaching 97% of the population across Ireland and 4G coverage reaching 99.4% of the population.
According to ComReg, the company held a 49.9% share of total mobile subscriptions during the first half of this year.
Three said it continued to make significant investment in connectivity across the country over the past 12 months, including the completion of a €1.2 million programme of 4G and 5G upgrades at some of Ireland’s busiest stadiums, entertainment venues, transport hubs and retail destinations, including Croke Park, Aviva Stadium, 3Arena, Dublin Airport and Dundrum Town Centre.
It also said it has invested more than than €2 billion in its Irish business since 2015 as part of its long-term commitment to delivering a high-capacity, resilient network.
This investment includes €1.1 billion spent on network and IT infrastructure to improve performance in high density areas, according to the mobile operator.
Commenting on the results, Elaine Carey, CEO of Three Ireland, said: “We’ve continued to invest in the network and services that keep people connected, expanding 5G coverage, upgrading infrastructure across the country and helping to protect customers from scam and fraud calls.
“These investments, alongside the commitment of our people, are helping us deliver better outcomes for our customers every day. As we look ahead to the rest of 2026, our focus remains on delivering the connectivity, service and experiences our customers need and expect,” said Ms Carey.
