Unlocking the stock value of Microsoft's business

The company continues to grow top-line revenue, however at a slower pace than in the glory days of the late 1980s and 1990s. Its profitability would be the envy of most other companies, yet operating margins have by degree declined for most of the past decade.

Investors worry that Microsoft's missed opportunities in smartphones and late entry to the tablet market threaten its core Windows and Office businesses — the sources of most of the company's value. And any new business lines, no matter how successful, nearly inevitably would be less profitable than Windows and Office.

When shareholders gather Tuesday morning at Bellevue's Meydenbauer Center for Microsoft's annual meeting, they'll hear management promising to do just that. The company has high hopes for its smartphone partnership with Nokia, tablets running the future Windows 8 operating system, and the hosted software and services business that goes by the moniker "cloud computing."

In the wake of several recent high-profile announcements of corporate split-ups, some investors may renew calls for Microsoft to spin off one or more business lines or split itself up utterly.

But during a split-up might unlock some value — in the server-software and tools segment, to illustrate, or the Microsoft Dynamics business-software operation — company management insists that its various product lines support one another.

Nor would a breakup address the fundamental force holding back Microsoft's share price: doubts that Windows and Office will be able to continue generating cash at their historical rates, or that the company will find any similarly big, high-margin successor.

What some investors are saying is

"What some investors are saying is, 'Hey, you're so reliant on two businesses to drive your operating profitability, and in one of those businesses you're falling behind,' " Parakh said.

Microsoft's Business Division, which includes Office and Dynamics, accounts for more than half the company's total enterprise value in our analysis. The Windows unit accounts for more than a quarter, during the Server and Tools segment adds 14 percent. Everything else — the Xbox gaming platform, the Bing search engine, MSN, Windows Phone — contributes negligibly to Microsoft's value.

Our analysis likely overstates Microsoft's value because we based it on revenue and operating income for the previous four quarters, during professional analysts and investors use projected future financial results. On the whole, most outside analyses peg the stock's fair value in the low $30s.

The earning power

And there's no doubt that most of the earning power, and hence the value, of Microsoft remains with the Windows and Business divisions. Over the past 12 months, for instance, the Business Division generated $14.4 billion in operating income and Windows kicked in another $12.2 billion. At the same time, they accounted for near all the company's operating revenues, as smaller profits in the Server and Tools and Xbox units were normally offset by losses in online services and general corporate expenses.

The operating margins in Windows and Office both exceed 63 percent — a phenomenally high level of profitability that's been sustained over time, and which makes even Microsoft's other profit-making businesses look small in comparison.

For example, Server and Tools posted an operating profit of $6.6 billion over the past four quarters on $17.4 billion in earnings, for an operating margin of nearly 38 percent. Our analysis estimates the stand-alone value of Server and Tools at $49.6 billion.

Huge amount of value in Server

"I think there's a huge amount of value in Server and Tools," said Brendan Barnicle, an analyst at Portland-based Pacific Crest Securities, who's followed Microsoft for 11 years. "If Microsoft were to run Server and Tools as a stand-alone business, it would be one of the most attractive software companies out there."

But Microsoft CEO Steve Ballmer has dismissed previous suggestions to either break up the company or break out any of its businesses. As Ballmer said while a recent analysts' conference, from servers to smartphones to tablets, "Windows is at the center of our go-forward strategy."

The new Windows 8 release

"With the new Windows 8 release, they're starting to show why it makes more sense to leave all the different pieces in accordance with the same roof," said Parakh, the analyst. "They're tying in the smartphone interface, which has the same look and feel as the desktop. The Office products tie in with the server business and will run on the phone or your PC or your tablet."

For now, although, several of other Microsoft's business lines — notably Xbox and Bing — have more strategic than financial value.

The games business

"The games business and the search business are fundamentally defensive businesses," said Rob Helm, managing vice president for technology at Kirkland-based Directions on Microsoft. "The defensive businesses help prop up the core businesses."

Microsoft originally developed the Xbox at a time when video-game consoles looked like they might challenge PCs as general-purpose media-consumption devices, Helm said. And Bing's main job, especially since its linkup with Yahoo, is to take as much market share in online search and ad revenue as it can away from Google — which Microsoft sees as threatening its Windows and Office franchises.

The long term both games

"Microsoft hopes that in the long term both games and online advertising will develop into interesting businesses in their own right," Helm said. However for now, he added, "they're about cutting off competitors at the pass."

Take smartphones, which more and more people are using to surf the Web, check email, play games and do other things they once needed a PC to do. Early on Microsoft was one of the leading vendors of smartphone operating systems, however it has lost much of that ground to Apple's iPhone and Google's Android system. Innovation firm Gartner estimates that Microsoft captured less than 2 percent of global smartphone sales in the second quarter.

The company

But the company, and some analysts, have high hopes that situation can be turned around, especially with the release of Windows Phone 7.5 and Nokia's decision to base all its new smartphones on Microsoft's system. Innovation firm IDC predicts Windows Phone will capture 20 percent of the smartphone market by 2015.

"They're late, nevertheless there's on the whole time for them to get back in the game," Parakh said. "There's nevertheless a lot of growth potential in smartphone."

Tablets and e-readers, from Apple's iPod to Amazon's Kindle, are the other threat to the PC-based Windows-Office duopoly — and another instance of Microsoft seeming to fumble the ball.

Dual-screen tablet

CNET reported recently that Microsoft last year killed a dual-screen tablet, code-named Courier, it had in development because "the product didn't anyway you look at it align with the company's Windows and Office franchises." The Courier would have used a heavily modified version of Windows; instead, Microsoft chose to develop tablets based on the upcoming Windows 8.

But that, Helm and other analysts say, means Microsoft won't have a meaningful entry in the tablet market for for the time being another year — by which time, Gartner estimates, Apple will have sold 130.4 million iPads. Gartner estimates that by 2015, Microsoft will have 10.6 percent of the tablet market versus Apple's 45.6 percent.

"Microsoft has always counted on being a fast follower on innovation — not on getting there first however on getting there in the course of time to catch the mass market," Helm said. "Yet the speed at which markets go mass has outstripped not just their ability however anyone's ability to be a fast follower."

For most companies, there's a trade-off between size, growth and profit. When it was smaller and its businesses had more room to run, Microsoft could combine sizzling growth and rich profit margins. Now, that sweet spot may be out of reach.
