The global mining titan has delivered a record payout to shareholders but its underlying result has fallen short of expectations.

EHE - ESTIA HEALTH - up 22 cents, or 8.4 per cent, to $2.85

The aged care provider has kept its full-year profit flat amid what executives call one of the sector's most difficult periods ever.

OSH - OIL SEARCH - up seven cents, or 1.1 per cent, to $6.57

Oil Search says its first-half profit has more than doubled but uncertainty over a crucial natural gas agreement in Papua New Guinea is weighing on the oil and gas producer.

VRT - VIRTUS HEALTH - down 31 cents, or 6.3 per cent, to $4.60
