Facebook hires Google exec, hitting Google shares

By Eric Auchard

SAN FRANCISCO (Reuters) - Facebook said on Tuesday it had named Google Inc's global sales head, Sheryl Sandberg, as the social networking site's new chief operations officer, accelerating a decline in Google shares to year lows.

Google shares slid as much as 4.6 percent, trading below a 52-week low for the first time since its IPO and removing a technical crutch that had supported the stock.

The departure of Sandberg, who in six years at Google was instrumental in developing its fast-growing online advertising business, marks one of the first senior executives at the Web search leader to leave since its sensational initial public offering in August 2004.

"Sandberg's departure is a significant loss for Google," RBC Capital analyst Jordan Rohan said. "It signals that the company has reached a level of scale and bureaucracy with which some early Google employees are uncomfortable."

"It is a significant move," Oppenheimer analyst Sandeep Aggarwal agreed. "This could be the start of others leaving."

Chief Financial Officer George Reyes said he would retire last August, the three-year anniversary of Google's IPO, when pre-IPO stock options had fully vested for executives. Reyes remains at Google as it seeks to hire a replacement.

Symbolically, Sandberg's hiring represents a passing of the crown as Silicon Valley's hottest start-up from Google to Facebook, which has gained momentum over the past year.

"While there is no comparison between Google and Facebook in revenue terms, Facebook, in terms of popularity and impact, has a very similar profile to the pre-IPO Google," Aggarwal said.
