ZYNGA, the online social-game developer that has seen its share price roughly halved since a high-profile initial public offering, issued a lacklustre second-quarter earnings report that only ate away further at the company's market value.
Zynga also sharply lowered its outlook, helping send shares into a free fall in after-hours trading.
The publisher of games such as FarmVille and Words With Friends reported a loss for the second quarter of $US22.8 million, or three cents a share, compared with a year-earlier profit of $US1.4 million, or about break even on a per-share basis.
Adjusted earnings were five cents a share, Zynga said, while revenue bookings rose 10 per cent to $US302 million.
