Investors question Microsoft’s AI returns despite strong earnings

Microsoft delivered a strong earnings report on Wednesday, reporting $81.3 billion in revenue for the quarter, representing 17% growth. The company also reported net income profits of $38.3 billion, up 21% year-over-year, while Microsoft cloud revenue exceeded $50 billion. Despite these strong financial results, the company’s stock price declined on Thursday. Investors are concerned about the level of spending on cloud infrastructure and whether these massive investments will yield returns.

To support its AI lab partners, including OpenAI and Anthropic, Microsoft is aggressively scaling its capital expenditures. The company spent $88.2 billion on capital expenditures last year and has spent $72.4 billion so far this year. This rapid increase in spending has raised questions among investors about the timeline for profitability and whether the massive buildout of data centers will translate into actual enterprise usage.

To justify this spending, CEO Satya Nadella highlighted growth in AI adoption across the company’s product suite. However, some of the user growth metrics remain difficult to verify independently. For instance, Nadella stated that daily users of consumer Copilot AI products grew nearly 3x year-over-year, though the company did not specify the exact number of users. A Microsoft spokesperson stated that total monthly active Copilot users reached 150 million, up from 100 million last year, a figure that combines both commercial and consumer users.

More concrete adoption metrics were shared for Microsoft’s paid enterprise and developer products:

• GitHub Copilot: The coding assistant now has 4.7 million paid subscribers, representing a 75% increase year-over-year, out of a total of 20 million users (including free tiers) reported last year.
• Microsoft 365 Copilot: The AI assistant for the Microsoft 365 productivity suite has reached 15 million paid seats, out of a total base of 450 million paid seats.
• Dragon Copilot: The healthcare AI assistant, which competes with startup Harvey, is available to 100,000 medical providers and was used to document 21 million patient encounters over the quarter, representing a threefold increase year-over-year.

Nadella and CFO Amy Hood defended the infrastructure investments on the earnings call, stating that demand for AI services across products outstrips data center supply.

Despite these metrics, Wall Street remains cautious. The primary concern is that Microsoft’s core cloud and productivity segments did not grow as rapidly as anticipated. Karl Keirstead, a Wall Street analyst for UBS, noted: “The fact that BOTH Azure and the M365 segments fell a bit short is the key negative we’re hearing.” Azure is Microsoft’s cloud platform, and M365 refers to the Microsoft 365 productivity suite.

Why it matters

Investors are questioning whether Microsoft’s massive capital expenditures on AI infrastructure will translate into actual usage and profitability, despite the company’s strong earnings report.
