What Is The Biggest Threat To Microsoft Stock?
Buyers are paying for growth, and Microsoft (MSFT) is delivering it. The stock returned 37.2% between July 17 and October 15, 2026, against 4.1% for the S&P 500. Revenue climbed 17.7% in fiscal Q4 2026 from a year earlier. Yet on a July 29 earnings call, executives described a cost to that growth that is still rising. What is that cost, and who is raising it?
Microsoft Is Spending Heavily To Meet AI Demand
The cost is the AI capacity Microsoft is building, and the company’s executives raised it on that same call. Customer demand still exceeds the capacity Microsoft has available, management said. In July, the company expected to spend over $50 billion on capital in fiscal Q1 2027, covering the July to September quarter. This figure includes the effect of a change in how it counts some leases. Microsoft also expects capital spending for fiscal 2027 as a whole to grow from the year before.
That heavy spending already shows in Microsoft’s financial results. Gross margin was 67.2% in fiscal Q4 2026, against 68.6% a year earlier. Management attributed this decline to a shift in sales toward Azure and to continued investment in AI infrastructure. Free cash flow, the cash left after that spending, fell to $19.6 billion from $25.6 billion a year earlier, even as cash from operations rose.
Microsoft’s Cloud Business And The Price You Pay
Microsoft’s Intelligent Cloud segment brought in $39.3 billion in fiscal Q4 2026. This accounted for more than two-fifths of the company’s revenue and represented 32% growth from a year earlier. No other Microsoft segment grew as fast during that quarter, and revenue in Azure and other cloud services grew 43%. Microsoft is building capacity to keep up with precisely this growth.
At today’s price, there is little room for that spending to disappoint. Microsoft stock trades at 30.0 times its earnings over the past twelve months, against 22.7 for the S&P 500. At the end of June, the same earnings were priced at 20.7 times, the lowest at any quarter end since fiscal 2017. On October 15, the shares closed less than 1% below their highest close of the past year. The current stock price appears to assume the spending will pay off.
How Serious Is The Spending Risk For Microsoft?
Microsoft shareholders face a real but slow risk. Operating margin was 45.1% in fiscal Q4 2026, against 44.9% a year earlier, meaning Microsoft still keeps a slightly larger share of its sales as operating profit. For fiscal 2027 as a whole, management expects operating margin to be down less than 1 point, even as the company invests to meet growing demand.
So far, the cost shows up in Microsoft’s cash and its gross margin, while operating margin has held steady. Free cash flow is the key metric to watch in Microsoft’s next report, which will cover the July to September quarter.
