Staff at five Irish radio stations owned by Onic have been told a consultation process is under way that could result in job losses.
Directors at Dublin's FM104 and Q102, Limerick's Live 95, Cork's 96FM and LMFM will be leaving the business in the next few weeks.
Staff were told about the review at a meeting today.
An Onic spokesperson said: "While the landscape remains challenging for all media businesses, we remain focused on evolving Onic to ensure our long-term success, leaning on digital transformation, operational efficiency, and a proven track record of delivering great content to our loyal listeners."
RTÉ News understands that Onic is looking at having a more centralised business operation with no individual station directors.
In May, accounts filed by the Rupert Murdoch-owned Onic Audio showed that earnings declined by 19% to €2.2m due to reduced revenues and increased costs.
Earnings before interest, tax, depreciation and amortisation reduced from €2.73m to €2.2m in the 12 months to last June.
This followed revenues dipping marginally from €23.37m to €23m as the group's cost base rose from €26.12m to €26.66m.
