Is Microsoft (MSFT) Below Fair Value After Heavy AI Spending?

Microsoft stock is coming off a weak year, with the share price down 22.2% over the past 12 months, yet the current checks suggest the market may be pricing it below what its fundamentals and cash flows imply, as both the Discounted Cash Flow (DCF) intrinsic value estimate and earnings multiples point to undervaluation.

• Over the past 5 years Microsoft has returned 41.7%, which shows that even with the recent pullback, long-term holders have still seen a solid gain.
• Heavy investment in AI infrastructure and partnerships can support expectations for future cash generation, while concerns over capital intensity and sector-wide sentiment remain a key risk to how much value the market is willing to ascribe today.
• Microsoft screens as undervalued on all of Simply Wall St's broader checks, with a value score of 6 out of 6, which is also backed up by a DCF intrinsic value estimate suggesting the shares trade about 31.0% below that level and by market multiples that also lean cheap.

The issue now is whether Microsoft’s current price around US$393.82 already reflects these risks or still leaves a meaningful discount to intrinsic value.

Is Microsoft Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model estimates what Microsoft is worth today based on the cash it can generate for shareholders over time. Microsoft produced about $93.7b of free cash flow over the latest twelve months, and the model applies a growing cash flow profile on top of that base using a 2 Stage Free Cash Flow to Equity approach.

On these assumptions, the DCF model points to an intrinsic value of around $570 per share, compared with the recent share price near $393.82, implying the stock screens roughly 31.0% undervalued. The heavy AI and data center spending highlighted in recent news, including Microsoft's planned $190b of capital expenditures through 2026, helps explain why the market is cautious even though the cash flow model supports a higher valuation.

Taken together, the discounted cash flow work suggests Microsoft stock currently looks undervalued relative to its estimated intrinsic value.

Is Microsoft Still Cheap on Earnings?

The P/E ratio is a useful yardstick for Microsoft because earnings remain a core anchor for how investors value its mix of software, cloud and AI businesses. At a current P/E of about 23.4x, Microsoft trades below both the broader software industry average of 28.6x and the peer group average of 27.8x, even as it sits in the large cap, higher quality end of that group.

Simply Wall St’s fair P/E ratio for Microsoft is 42.7x, which reflects what investors might typically be willing to pay given its margins, scale, sector and risk profile. Compared with that fair multiple, the current 23.4x implies a sizeable discount, suggesting the recent reset in sentiment and sector multiples has not fully closed the gap that quantitative models see between Microsoft’s earnings power and where the stock is priced today.

On earnings multiples, Microsoft stock currently screens as undervalued relative to both its tailored fair P/E and standard industry benchmarks.

The Bottom Line

For investors weighing Microsoft today, both the Discounted Cash Flow (DCF) intrinsic value estimate and the earnings multiples are pointing in the same direction, suggesting the stock appears undervalued rather than fully priced. The core question is whether the cash flows assumed in that intrinsic value view will materialise after heavy AI and data center spending, or whether higher capital intensity limits how much of that value reaches shareholders.

From here, the debate largely comes down to one issue: whether Microsoft can sustain attractive returns on that planned investment so that the current discount reflects an opportunity, or whether the market is correctly pricing in execution and spending risks.
