Cable television operator NTL Ireland recorded revenue of £19.3m (€27.7m) in the final quarter of 2004, up 3.2% on the same period last year.
NTL's parent company is currently considering offers for the Irish business, with Chorus owner UGC said to be among the bidders.
A statement from the parent company NTL said the rise was due mainly to greater take-up of digital television services and higher prices.
Customer numbers rose by 4,100 to 347,800, while the company now has 76,200 digital television and 7,500 broadband customers. The company no longer breaks down its Irish profits figure.
Parent company NTL said its 2004 revenues grew by 5.7% to £2 billion. Net losses were reduced from £583.7m in 2003 to £484.2m.
