Bangalore: David Ebersman, the man behind Facebook’s failed IPO is company’s well-liked, boyish-looking 41-year-old chief financial officer. He’s not as well known as CEO Mark Zuckerberg or COO Sheryl Sandberg.

Facebook’s stock reached a new low on Friday, closing at $18.06. The company has lost more than $50 billion in market value in three months after the offering that’s more than what Lehman Brothers gave up in the entire year before it filed for bankruptcy.

It is not talked much but if there is one single individual more responsible than any other for the stunning mispricing of Facebook’s I.P.O., it is Ebersman. He signed off at $38 after the company had originally planned a price range of $29 to $34. Also he pushed to 25 percent more shares than initially planned.

Ebersman seems to have poorly misjudged the demand for Facebook’s I.P.O. aided by errant advice from banking advisers like Morgan Stanley, JPMorgan Chase and Goldman Sachs who all had an incentive to sell as many shares as possible at the highest price possible. This wasn’t a traditional I.P.O. and should never have been priced that way.
