Mirvac has lifted its interim dividend following a 21 per cent gain in first-half operating profit to $352 million, though the building firm’s net result slipped over the period.

The company said revenue for the six months to December 31 increased 4.0 per cent to $1.62 billion – driven by an increase in residential settlements during the period – though net profit slipped 5.0 per cent to $613 million as a result of higher net valuation gains on investment properties in the same period a year ago.

Nonetheless, the company increased its unfranked interim dividend to 6.1 cents, from 5.3 cents a year ago.
