Bank of Ireland has entered into exclusive negotiations with cash machine operator Euronet for the sale of around 750 non-branch ATMs.
Euronet, which already operates 600 cash machines in Ireland, is believed to have tabled a bid of close to €20m for the portfolio.
This follows last week's announcement that AIB has agreed to sell more than 500 non-branch ATMs to Brink's.
A spokesman for Bank of Ireland refused to comment on potential buyers of the portfolio.
"Over the past number of months, Bank of Ireland has been strategically reviewing its non-branch ATM fleet," he said. "The bank commenced a tender process for the potential sale of this fleet and this tender process remains ongoing.
"Bank of Ireland has the largest branch network of any individual bank in Ireland. In the event of a sale, the bank will continue to operate over 750 ATMs from more than 250 branches, where we have upgraded services and invested in rural and urban locations. The bank has invested €21m in this network since 2018."
As part of a sale, Bank of Ireland would ensure there was no change to charges for domestic customers for a number of years. Many ATMs are located in shops and would remain on the same terms with retailers.
