Is Microsoft Stock Undervalued? What the Numbers Say in 2026

Microsoft stock has a specific problem in 2026: the numbers say one thing and the price says another. Figuring out which one is right requires looking at the valuation from several different angles rather than settling on a single metric and calling it done.

The stock is trading around $355. The average analyst price target is above $560. The business is growing at 18% annually with a committed revenue backlog approaching $630 billion. At approximately 21 times earnings, Microsoft stock is trading at one of its lowest multiples in years.

That combination either means the stock is genuinely undervalued and the market will eventually correct the mispricing, or it means the multiple compression is justified and the earnings quality story is weaker than the headline numbers suggest. Both possibilities deserve honest examination.

What 21 Times Earnings Actually Tells You

The price-to-earnings multiple is the starting point for any undervaluation argument, and Microsoft's current multiple is the most compelling part of the bull case.

At approximately 21 times forward earnings, Microsoft is trading at a discount to its five-year average multiple and at a discount to most of its large-cap technology peers. A company growing revenue consistently at 18% year over year with highly recurring revenue streams from enterprise software subscriptions, cloud infrastructure, and AI services does not typically trade at 21 times earnings for long.

The question is whether the current multiple reflects a genuine opportunity or a genuine warning. Multiple compression happens for two reasons: either investors are pricing in deteriorating earnings, or investors are applying a lower multiple to earnings they expect to grow. The evidence from Microsoft's recent quarters suggests the latter. Revenue growth has been consistent, earnings have beaten estimates repeatedly, and the forward revenue visibility is unusually high.

When a company with strong earnings growth trades at a compressed multiple, it usually means one of two things: the market has made a mistake that will eventually self-correct, or the market knows something about future earnings that the current results do not yet show. The capex concern is the specific version of the second possibility that investors are pricing in.

The Price-to-Sales Perspective

Earnings multiples can be distorted by accounting choices and one-time items. Looking at price-to-sales gives a different angle on the valuation question.

Microsoft's market cap of approximately $2.64 trillion against annual revenue running above $230 billion gives a price-to-sales ratio of roughly 11 times. For a software and cloud business with the margin profile Microsoft has historically maintained, that is not an obviously stretched valuation. It is a premium to industrial companies and financial businesses, as it should be given the recurring revenue quality and growth rate. But it is not the kind of multiple that requires heroic assumptions to justify.

The more relevant comparison is against Microsoft's own history. A year ago, when the stock was trading near $550, the price-to-sales multiple was considerably higher. The business has grown since then. The multiple has compressed more than the growth rate declined. That asymmetry is one of the cleaner signals that something besides business fundamentals is driving the current price.

The Backlog as a Valuation Signal

One number that does not get enough attention in the Microsoft undervaluation debate is the commercial remaining performance obligations, or RPO essentially the committed revenue backlog.

Microsoft's commercial RPO sits near $630 billion, up roughly 99% year over year. That number represents contracts already signed where revenue has not yet been recognized. It is not a forecast. It is a legal commitment from customers to pay Microsoft for services they have already agreed to purchase.

A $630 billion backlog on a company with a $2.64 trillion market cap means that Microsoft has already secured enough committed future revenue to cover a significant portion of its current market value without winning any new business. That is an unusual level of forward visibility for any company of this size.

Valuation frameworks that rely on discounted future cash flows typically assign significant value to revenue certainty. The higher the visibility, the lower the discount rate the market applies, and the higher the implied valuation. The fact that Microsoft's stock price has fallen significantly despite a near-doubling of its committed revenue backlog suggests the market is currently weighting the capex concern over the revenue visibility in a way that may not be sustainable long term.

Understanding why committed revenue backlogs matter requires understanding how AI is fundamentally changing the way enterprises buy and deploy technology. At a recent WEEX event in Amsterdam, industry experts explored exactly this shift, how AI agents are reshaping enterprise software adoption and what it means for cloud infrastructure demand.

Where the Undervaluation Argument Has Limits

The honest version of the undervaluation case acknowledges the places where the numbers are less clean.

Free cash flow is the area where the capex spending shows up most directly. When a company spends aggressively on infrastructure, free cash flow margins compress even when earnings look healthy on an accounting basis. Microsoft's free cash flow per share has been under pressure in a way that is not visible in the earnings per share figures. Investors who value companies primarily on free cash flow rather than reported earnings will arrive at a different valuation than investors using the earnings multiple alone.

The OpenAI investment losses running at several billion dollars annually are another complication. These losses flow through the income statement in ways that affect the earnings quality picture. A business that is simultaneously growing Azure revenue at 40% and absorbing billions in losses from an investment in a partner-turned-competitor is harder to value cleanly than the simple earnings multiple suggests.

Return on invested capital is the metric that will ultimately determine whether the undervaluation argument is correct. If Microsoft's $190 billion in annual capital expenditure generates returns above its cost of capital, the current multiple looks like an opportunity. If the returns fall short, the multiple compression is justified and may persist. That question will only be answered over the next several years as the AI infrastructure investment cycle matures.

What Comparable Companies Are Trading At

One useful way to assess whether Microsoft stock is undervalued is to compare its valuation against peers with similar business characteristics.

Among large-cap technology companies with significant cloud and software revenue, Microsoft at 21 times earnings looks compressed relative to the group. Companies with lower growth rates and less recurring revenue often trade at higher multiples, which is the kind of anomaly that typically gets arbitraged away over time as investors rotate toward better value.

The comparison that matters most is against the business Microsoft was two years ago versus the business it is today. Revenue is higher, backlog is higher, AI revenue has been added, Copilot is generating real enterprise subscription revenue. The stock is lower. Something in that comparison does not add up in a way that favors the bears over a multi-year horizon.

The Dividend and Buyback Contribution

One aspect of Microsoft's valuation that gets underweighted in growth-focused analysis is the capital return program.

Microsoft pays a dividend yielding approximately 0.97% at current prices. That is not a large yield in absolute terms, but for a technology company it represents a meaningful commitment to returning capital to shareholders. More importantly, the buyback program reduces share count over time, which mechanically increases earnings per share even in periods of flat earnings growth.

At $355, Microsoft's buyback program is retiring shares at prices that the analyst community broadly considers to be well below fair value. The capital return program is not a primary valuation driver, but it adds a mechanical support to earnings per share growth that compounds over time in favor of long-term holders.

Is Microsoft Stock Actually Undervalued?

The numbers suggest yes, with a specific caveat.

Microsoft stock appears undervalued relative to its historical multiple, relative to peers with comparable or lower growth rates, and relative to the forward revenue visibility implied by its backlog. The 21 times earnings multiple on a business growing at 18% annually with near-$630 billion in committed future revenue is difficult to justify as fair value in any traditional framework.

The caveat is that undervalued and immediately re-rating are different things. A stock can be undervalued for an extended period if the catalyst for multiple re-expansion has not yet arrived. For Microsoft, that catalyst is likely the July 29 earnings report and whatever signal management provides about the capex trajectory and Azure growth sustainability.

If the July report confirms that Azure growth is holding and that the free cash flow trajectory is improving, the market has less justification for the current multiple discount. If the report disappoints, the undervaluation argument needs to wait for more evidence.

Conclusion

The numbers make a reasonable case that Microsoft stock is undervalued at $355. A compressed multiple on a growing business with unusual revenue visibility and a near-doubling backlog does not fit the profile of a stock trading at fair value.

What the numbers cannot tell you is when the market decides to close that gap. The capex concern is real, the earnings quality questions around free cash flow compression are legitimate, and the catalyst for re-rating may be as close as the July 29 earnings report or as far as 2028 when the infrastructure investment cycle more clearly shows its returns.

The undervaluation case is strongest for investors who can hold through the uncertainty. The question is not whether Microsoft is cheap. The evidence suggests it is. The question is how long cheap stays cheap before something changes the market's mind.

FAQ

1. Is Microsoft stock undervalued in 2026?
By most traditional valuation metrics, yes. At approximately 21 times earnings on a business growing 18% annually with a near-$630 billion committed revenue backlog, Microsoft appears to be trading at a discount to fair value relative to its historical multiple and peer comparisons.

2. Why is Microsoft stock trading at such a low multiple?
Concerns about $190 billion in annual capital expenditure compressing free cash flow margins, the evolving OpenAI relationship, quantum computing credibility questions, and broader investor rotation have driven multiple compression that appears disconnected from the underlying business performance.

3. What is Microsoft's price-to-earnings ratio right now?
Microsoft is trading at approximately 21 times forward earnings, well below its five-year historical average and below most large-cap technology peers with comparable or lower growth rates.

4. What would cause Microsoft stock to re-rate higher?
The July 29 earnings report providing evidence that Azure growth is holding and free cash flow margins are on a recovery trajectory would be the most immediate catalyst. Longer term, the capex cycle peaking and margins recovering would support a higher multiple.

5. How does Microsoft's backlog affect its valuation?
The nearly $630 billion committed revenue backlog, up roughly 99% year over year, represents contracted future revenue that provides unusual forward visibility. Valuation frameworks that weight revenue certainty should assign significant value to that visibility, making the current multiple look compressed relative to the fundamental quality of the earnings stream.
