Yahoo Inc. (NDAQ:YHOO) would be worth far more to shareholders if it underwent a breakup or outsources its web search functionality to Google, according to an analyst note issued today. Shareholders supported the analysis with shares jumping over 2 percent in today's action.

Jeffrey Lindsay, an analyst at Sanford C. Berstein, said Yahoo's shares could be valued as high as $38.65 per shares compared to its current price of $27 per share if it underwent a breakup into three units. The Display Advertising Unit - using DoubleClick's valuation - could be worth $25.5 billion. The Search Unit - using Google and Ask.com valuations - could be worth $15.6 billion. And finally, its Subscriptions business - using Match.com and RealNetworks valuations - could be worth $1.3 billion.

Lindsay also offered a second analysis of what would happen if Yahoo outsouced its search business to Google. The projections showed search revenues rising 28% in 2008 bringing total revenues up 16% over current projections. Meanwhile, the search company could cut 25% of its staff, which would drop its expenses by 17%. In the end, this would improve operating income by 205% over current Wall Street estimates.

"It appears that Yahoo will not take bold measures to right the ship," he wrote in a research report. "We believe that Yahoo still has a potentially high intrinsic value. We believe, however, that to stop the inevitable slide into irrelevance the management team must consider more radical actions and strategies."

In the end, Yahoo's management is unlikely to take either action in favor of organicly growing the company. Unfortunately, the company's main display advertising business appears to be fledging amid troubles capitalizing on its ad networks. Meanwhile, its search business continues to be second to Google. Maybe shareholders should vote Lindsay as director of the board...
