And finally, Plexus ( PLXS) was the big loser in after-hours action after the company announced it's no longer a supplier for Juniper Networks ( JNPR). Neenah, Wis.-based Plexus, which provides electronic manufacturing services, said it learned of Juniper's decision on Monday and that while it's unclear on the exact timing of the transition, it expects it will occur by the end of its current fiscal year. "This is very surprising news to us given our recent communications and activities with Juniper, including the recent award of Juniper programs and our collaboration with Juniper on activities to support their competitiveness," said Dean Foate, the CEO and president of Plexus, in a statement. "Plexus has been an important strategic supplier to Juniper for more than a decade. While this is a significant event for us in the near term, our new business wins of $956 million during fiscal 2012, including in the networking/communications sector, provides us continued optimism in our strategy." The stock was last quoted at $21.35, down 23%, on volume of more than 115,000, according to Nasdaq.com. Another company seeing active trading in Tuesday's extended session was News Corp. ( NWSA), whose shares were up nearly 3% following the media giant's quarterly report. News Corp. posted fiscal first-quarter earnings of $2.23 billion, or 94 cents a share, on revenue of $8.14 billion, up from a year-ago equivalent profit of $738 million, or 28 cents a share, on revenue of $7.96 billion. Excluding items, News Corp. reported adjusted earnings of 43 cents a share, beating Wall Street's consensus view of 37 cents. -- Written by Michael Baron in New York. >To contact the writer of this article, click here: Michael Baron.
