imgresExpedia, based in Bellevue, Washington, announced Wednesday plans to buy Austin-based HomeAway in a deal worth about $3.9 billion.

That represents a per share price for HomeAway of $38.31, based on Expedia’s closing price on Nov. 3. Under the terms of the deal, Expedia will offer to acquire each outstanding share of HomeAway’s common stock for $10.15 in cash and .2065 of a share of Expedia common stock.

Bringing HomeAway into the Expedia, Inc. family and adding its leading brands to our portfolio of the most trusted brands in travel is a logical next step,” Dara Khosrowshahi, Chief Executive Officer of Expedia said in a news release.
