Eircom has decided against listing on a public market following a strategic review.
"There are encouraging signs of positive momentum in the business," a company statement read.
"Our primary focus over the coming months will be to accelerate this momentum, to continue to improve our financial performance and to realise the benefits of our significant investment programme which will deliver value to all our stakeholders.
"Therefore, the company has concluded this strategic review and does not intend to proceed with an IPO at this time.
"We have discussed this decision with our key shareholders.
"These shareholders expressed their clear preference to continue participating in the upside from the significant network investment made in recent years, which has only recently begun to manifest itself in the company's operating and financial results."
