| Sun Microsystems Inc. is back in the black, but investors are questioning whether the notoriously boom-and-bust company can remain profitable for the long term. For the three months ended Dec. 31, the server and software maker earned $126 million, or 3 cents per share, up from a net loss of $223 million, or 7 cents per share, in the year-ago period. Fiscal second-quarter revenue totaled $3.57 billion, up 7 percent from $3.34 billion a year earlier. Excluding special expenses, such as $58 million in stock-based compensation charges and $26 million in restructuring costs, Sun earned $148 million, or 4 cents per share. |
