Three Ireland has confirmed it will not be renewing its sponsorship of the Republic of Ireland soccer teams.
The company first came on board as primary sponsors of Ireland's international squads in the summer of 2010 in an agreement that was worth €7.5m over four years to the FAI.
Three last renewed its deal four years ago; that package was worth €8.9m.
However, 48 hours before the FAI are set to belatedly release their annual accounts for 2018 - it was rescheduled on Wednesday evening to Friday morning - the company confirmed they will not be extending their sponsorship beyond this summer.
The association has endured a tumultuous 2019 in the wake of revelations that former chief executive John Delaney had loaned the FAI €100,000.
Delaney has since left but Sport Ireland funding has been withheld and the Minister for Sport Shane Ross this week reiterated his call for "regime change" at the embattled association.
In a statement, the mobile phone operator said it is withdrawing from sports sponsorship entirely.
"Three has been a supporter of Irish football for 10 years with €30m invested in the game through our sponsorship fee and activations," said the company's Chief Commercial Officer Elaine Carey.
"Three has made the decision not to renew its sponsorship of Irish football when the current contract comes to an end at the end of July 2020.
"Having recently reviewed our full sponsorship portfolio, we have decided to consolidate our sponsorship investment in the area of music.
"At Three, we are entirely focused on supporting the Irish men's team through what we hope will be an exciting and successful qualification for the UEFA European Football Championship and the Irish women's team in their qualification journey for the UEFA Women's European Championship.
"We also wish the Irish teams at every level the very best in the future."
The FAI thanked Three Ireland for their "financial and personal support" on Thursday evening.
"In their ten years as proud backers of Irish football they have been Ireland's number one supporter and we will always be grateful to them for their financial and personal support," a statement read.
"We look forward to a successful eight months ahead with Three on board as we countdown to the Euro play-offs in March and the UEFA Euro 2020 games in Dublin next summer."
