Today SAP announced that its tender offer for all outstanding shares of Success Factors’ common stock is closed. The merger is expected to be completed in a few days, a SAP spokeswoman told SiliconANGLE.

The deal has been carried out via Saturn Expansion Corporation, an indirect subsidiary of the business software maker, and 81,673,335 shares have exchanges hands – about 95 percent of Success Factors’ stock.

“American Stock Transfer & Trust Company, LLC, the depositary for the tender offer, has indicated that, as of 5:00 p.m., New York City time, on February 15, 2012, 81,673,335 shares of common stock of SuccessFactors  have been tendered into and not withdrawn from the tender offer.

Saturn Expansion Corporation has accepted for payment all shares that were validly tendered and not withdrawn in the Offer.”

The deal was announced in December last year, when SAP said it has entered into an agreement to acquire the cloud-based HR solutions provider for $3.4 billion, a 52 percent premium over the latter’s stock price at the time. Success Factors’ investors received $40.00 per share.

The acquisition is – or rather was – a very large one, and naturally attracted the eyes of legislatures earlier this month. The EU decided to use up a second review period, which SAP noted was also the case during the 2007 buyout of Business Objects for over $6 billion.

The industry has reacted to both deals. Success Factors had its fair share of headlines, and SAP’s competitors responded with investments of their own. Most recently Oracle announced it has acquired Taleo for $1.9 billion; another HR SaaS provider.

The database giant has been at war with its competitor on the BI end for some time now, and throughout several fields. Oracle sued SAP on one occasion for industrial espionage, and today the two are battling it all out with their respective big data appliances.
