Rice Energy (RICE) shares shed more than 7 percent on Tuesday after announcing it will buy Vantage Energy (:VEI) for about $2.7 billion, including debt.

The company reported it will pay about $1.02 billion in cash and will assume $700 million in debt.

"This acquisition adheres to our proven strategy of pursuing core shale gas acreage, leveraging our industry-leading technical shale team to deliver best-in-class well results and capturing a greater share of the value chain through our premier midstream services business," Rice Energy CEO Daniel Rice said in a statement.

In addition, the independent oil and gas producer reported the pricing of a public offering of 40 million shares of its common stocks at $25.50 per share. Rice Energy will use these net proceeds towards funding Vantage Energy acquisition.

Even with Tuesday's declines, the stock has surged more than 129 percent so far this year.
