NEW YORK ( TheStreet) -- Sourcefire ( FIRE) fell in extended trading on Wednesday as investors looked past the Columbia, Md.-based cybersecurity company's better than expected third-quarter report to its outlook for a sequential slowdown in the sales growth in the current quarter. After the closing bell, Sourcefire posted an adjusted profit of $5.2 million, or 18 cents a share, on revenue of $36.2 million, for the three months ended Sept. 30, besting the average estimate of analysts polled by Thomson Reuters for earnings of 15 cents a share on revenue of $35.7 million. But the company said it expects adjusted earnings of 16 to 18 cents a share for the fourth quarter with revenue projected between $37 million and $38.5 million. That view compares unfavorably to Wall Street's current consensus estimate for a profit of 21 cents a share in the December period on revenue of $43.6 million.
The stock was last quoted at $24.88, down 19.7%, on volume of nearly 315,000. Based on a regular session close at $30.99, the shares were up more than 50% in the past 52 weeks. Earlier this week, the stock hit a 52-week high of $32.79 Elsewhere in afterhours action, Flextronics ( FLEX) was moving higher in late trades after the Singapore-based provider of electronics manufacturing services reported an adjusted profit of $179 million, or 23 cents a share, for its fiscal second quarter ended Oct. 1. That performance topped Wall Street expectations for earnings of 20 cents a share in the quarter. The stock was last quoted at $7.15, up nearly 12%, on volume of more than 285,000. Revenue totaled $7.42 billion in the quarter, up 27% from $5.83 billion in the same period a year earlier, and ahead of the consensus view of $7 billion. Flextronics also gave a positive outlook for the December quarter, forecasting adjusted earnings of 23 to 25 cents a share on revenue of $7.5 billion to $7.7 billion. Flextronics' performance and outlook could give a lift to shares of its fellow EMS companies Jabil Circuit ( JBL) and Celestica ( CLS) in Thursday's session. Another gainer in late trades was iRobot ( IRBT), whose shares were tacking on 9% to $21.10 on volume of around 50,000, according to Nasdaq.com. Again, earnings were the driver behind late trading as the Bedford, Mass.-based company, which makes robots for a variety of applications such as cleaning and security, reported a third-quarter net income of $7 million, or 27 cents a share, on revenue of $94.2 million, better than Wall Street expectations for earnings of 7 cents a share.
