ADC Telecommunications Inc (NASDAQ: ADCT), the Minnesota-based telecommunications equipment provider, nicely surprised Wall Street last night with better than expected revenue and earnings.

ADC reported Q3 earnings per share of $0.37 versus consensus estimate of $0.23. Revenue came in at $346 million versus consensus $333 million. The company increased guidance for the year slightly to $1.31 billion versus consensus $1.29 billion. However, EPS is being hiked nicely to $1.11-$1.15 per share versus consensus $0.92.

"Even though several key customers have not yet returned to normal spending following their mergers, we had better than expected strength in our connectivity, wireless and services businesses, and have seen resumed sales growth outside the United States," said Robert E. Switz, the company's president and CEO, in a statement.

However, despite management optimism, analysts are keeping their neutral ratings on the equipment provider, with both Merrill and Jefferies citing elusive revenue growth. The stock took a nice jump in after hours trading, up over $1.00.

I wouldn't chase the stock following its after-hours rally, but would wait for a pull back and then consider buying. Margins and cash are improving along with the industry's spending pattern.

Sun Microsystems, Inc. (NASDAQ:SUNW), proved the naysayers wrong this evening, posting quarterly results that far surpassed Wall Street's muted expectations. The computer server and software company, which was all but left for dead by investors after the dot-com collapse, is now solidly profitable in its second fiscal quarter.

Wall Street expected Sun to break even, but the company delivered profits of $126 million, or 3 cents a share. That's up from a loss of $223 million, or 7 cents a share a year ago.

Revenues hit $3.57 billion, up from $3.32 billion a year ago. That number was only slightly better than Wall Street was expecting ($3.52 billion). No doubt some analysts will still be wondering whether Sun can really grow again, or just acquire and slash its way to profitability.

Still, optimism by BloggingStocks readers was clearly warranted. In our poll, 72% of 218 readers who voted, predicted Sun would beat Wall Street's expectations.

Now the stock is surging after hours. The shares closed at $5.66 today, a drop of 9 cents. But as of 4:45, buyers were flocking to the stock at a price of $6.11.

Also likely to encourage more buying: Sun announced that private equity firm Kohlberg Kravis Roberts & Co. is taking a stake in the firm. No, they aren't buying the stock. They are buying Sun's senior convertible bonds. Still, that's a vote of confidence nonetheless.

Sun bulls, this is your time to take a bow.
