Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of networking gear maker Extreme Networks (NASDAQ:EXTR) soared 19% today after its Q2 outlook blew out Wall Street expectations.

So what: Extreme's Q1 results -- adjusted EPS of $0.06 on revenue of $75.9 million -- just managed to squeak past the consensus, but a particularly upbeat view of Q2 is forcing analysts to boost their valuation estimates yet again. Specifically, Extreme expects its recently completed acquisition of Enterasys Networks to double its revenue and be immediately accretive to the bottom line, giving investors plenty of good vibes over the company's growth trajectory going forward.

Now what: Management now sees Q2 adjusted EPS of $0.14-$0.16 on revenue of $140 million-$155 million, well above Wall Street's view of $0.06 and $78.4 million. "Over the next 18 to 24 months, we will merge Extreme OS and Enterasys' EOS into a single operating system that will run seamlessly across our entire portfolio," said Extreme CEO Charles Berger in a conference call. "Although it will take a quarter or two to combine the customer and prospect databases, we now have a state-of-the-art lead generation, lead nurturing and sales force automation infrastructure." With Extreme shares now up a whopping 110% over its 52-week lows and trading at a 60-plus P/E, however, much of that integration optimism might already be baked into the valuation.
