(Reuters) -Australia's Domain Holdings said on Friday U.S. online real estate firm CoStar ( CSGP ) would acquire the property classifieds company for an implied enterprise value of A$3 billion ($1.92 billion).

Under the deal, CoStar ( CSGP ) and its unit, which already owns a 16.9% stake in Domain, will acquire the remaining shares in the company at A$4.43 apiece, a 4.2% premium to the stock's last closing price on Thursday.

Domain may also decide to declare a special dividend of up to A$0.10 per share, which will reduce the deal value by that amount, it said.

The deal marks CoStar's ( CSGP ) first foray into the Australian market and could transform the landscape in a sector where listing volumes have sagged as high living costs slowed the country's hot housing sector but are improving with interest rates coming down.

For years, Domain has lagged behind the larger classifieds site realestate.com.au, which is owned by News Corp-controlled REA Group.

Domain's board has unanimously recommended that shareholders vote in favour of the proposed deal, which is also subject to Foreign Investment Review Board (FIRB) and other regulatory approvals.

Domain's 60% owner, Nine Entertainment ( NNMTF ), said in a separate statement that the deal "appropriately reflects the strategic value" of its interest in Domain and it intends to vote in favour of the deal in absence of a superior offer.

Nine expects to receive about A$1.4 billion in cash proceeds from the deal, and may decide to pay a special dividend in the range of 47 to 49 Australian cents per share.

As of 0044 GMT, Domain's shares were up 2.9% at A$4.375, their highest level since late-March, while Nine's shares were trading up 4%.
