Priceline (Nasdaq: PCLN) has agreed to acquire Norwalk, Conn.-based travel search site Kayak Software Corp. (Nasdaq: KYAK) for $1.8 billion, or $40 per share, in cash and stock. That represents nearly a 29% premium to where Kayak shares closed trading yesterday, and a whopping 54% higher than where the company went public in June 2011. It’s a remarkable ending for Kayak, which openly wondered if it would be crushed when Google agreed to buy ITA Software for $700 million in late 2010. The Norwalk, Conn.-based company filed for its IPO shortly thereafter, but waited more than 20 months before actually pulling the trigger. And, when it did go public, Kayak’s venture capital backers felt compelled to increase their ownership. As of last check, Kayak shareholders include General Catalyst Partners (6.08m shares), Sequoia Capital (6.07m), Oak Investment Partners (3.88m), Fidelity Investments (714k) and Wellington Management (688k).
