Private hospitals and day surgery operator Ramsay Health Care wants to continue its overseas expansion, including into new markets.
Ramsay operates hospitals in Australia, Indonesia, the United Kingdom and France.
Chief executive Christopher Rex on Tuesday said Ramsay would consider new "beachhead" investments.
"We're not confining our activities to markets where we already have hospitals. We are looking at other geographies as well," Mr Rex said.
Ramsay would not exclude more acquisitions in the United Kingdom, where the watchdog is investigating competition in the private health sector.
The UK Competition Commission is expected to release a draft report in the next six months.
Mr Rex said it would not be impossible for Ramsay to make more acquisitions in the UK before the Competition Commission released its report.
However, to do so would introduce a level of complexity which it would be nice to do without.
Fairfax Media on Tuesday reported that Ramsay would be interested in General Healthcare Group or Spire Healthcare in the UK.
Ramsay on Tuesday also upgraded its annual earnings guidance, after a strong start to the 2012/13 financial year.
Ramsay's first half net profit rose 10.1 per cent to $138.4 million in the six months to December 31, from $125.7 million a year earlier.
The group's underlying net profit, which excludes non-core items, rose 12.3 per cent to $148.2 million.
Ramsay expects to increase its full-year core net profit by 13 to 15 per cent.
It had previously forecast growth of 10 to 12 per cent.
Ramsay said its expansion program in Australia was paying dividends as new capacity at its hospitals met the growing demand for healthcare generated by an ageing and expanding population.
Australian hospital expansion continued to be a focus for Ramsay in 2013.
Meanwhile, Ramsay has extended Mr Rex's contract by three years.
His contract, originally due to expire in June 2013, will now run until mid-2016, then continue on a rolling basis or be terminated by either himself or Ramsay.
His fixed remuneration is currently $2.1 million, and he is entitled to short-term and long-term incentives.
Shares in Ramsay were 28 cents higher at $30.86 at 1547 AEDT on Tuesday.
