BEA Systems Inc, one of the major companies developing enterprise infrastructure software, will be acquired by Oracle Corp for $8.5 billion, a 14 percent premium to its first offer. The companies involved in the deal made their new plans public on Wednesday.

Oracle, one of the major developers of database management systems, tools for database development, middle-tier software, enterprise resource planning software, customer relationship management software and supply chain management software, will reportedly pay $19.375 per share to acquire BEA. A higher amount than the $17 per share it offered in October, but also under the $21 per share price formerly demanded by BEA.

"It's a fair price. It's a good deal for Oracle. It's a good deal for BEA," said Trip Chowdhry, analyst at Global Equities Research, for Reuters.

BEA shares climbed 19 percent to $18.50 in pre-market trading compared to the Tuesday close on Nasdaq of $15.58, while Oracle’s shares dropped 51 cents to $20.80 in pre-market trading from their close of $21.31.

Oracle, a corporation which has offices in more than 145 countries around the world, said the transaction, valued at $7.2 billion net of cash on hand of $1.3 billion, will boost its adjusted earnings per share by at least 1 cent to 2 cents in the first full year after the deal is perfected.

The deal might surprise some analysts, especially after last moth Oracle said a friendly deal couldn't be done with BEA's current board.

Oracle’s CEO, Larry Ellison, has purchased more than 35 companies and spent over $25 billion in the process.

"It is a lot more than what they initially offered,'' said Edward Lewis, a partner at Atlantic Equities LLP in London, in an interview. "BEA managing to flush out a higher offer from Oracle is obviously proof that their strategy worked.''
