A Group of Facebook shareholders is seeking to sell $1-billion worth of shares on the secondary market, a move that would value the company at more than $70-billion, according to five sources .
It would represent one of the largest transactions of Facebook shares to date and points to a growing wariness among early-stage investors and employees who fear Facebook's market valuation cannot keep pace with its growth.
The sellers have lowered their price after previously trying to sell shares at a price that valued the company at $90-billion. But buyers baulked.
"At the current valuation it is really hard to justify the investment," said Sumeet Jain, partner at venture capital firm CMEA Capital.
The deal, which includes stock held by employees, still needs approval from executives, including chief executive Mark Zuckerberg and chief financial officer David Ebersman, according to two sources.
Facebook declined to comment.
