Microsoft’s measured cloud growth indicates that the realization of AI’s potential benefits may require an extended timeframe.

Microsoft announced an increase in spending for AI infrastructure this fiscal year, despite a slowdown in cloud business growth. This indicates that the returns from their investments in technology may take longer than expected.

Shares initially dropped 7% in response to the spending forecast, but later recovered to trade down 4% after Microsoft's post-earnings call on Tuesday, where they stated that Azure cloud growth would accelerate in the second half of fiscal 2025.

Other major tech companies, such as Google-parent Alphabet, have also been investing heavily in data centers to take advantage of the AI boom, with Alphabet warning that its capital spending will remain high for the rest of the year.

Microsoft reported a 77.6% increase in capital spending to $19 billion for the fiscal fourth quarter ending June 30, with cloud and AI-related expenses making up the majority of the total. Throughout fiscal 2024, the company's capital spending amounted to $55.7 billion.

CFO Amy Hood emphasized that the investments were crucial to meet the growing demand for AI services and to develop assets that would generate revenue over a period of at least 15 years.

Despite the significant increase in Microsoft's stock value over the past year due to optimism surrounding AI, investors were disappointed with the growth of Azure. The company projected a 28% to 29% growth rate for the July-September quarter, slightly lower than the 29.7% estimate provided by Visible Alpha.

This forecast followed a 29% growth in the quarter ending June 30, falling short of the 30.6% estimate and indicating a slowdown compared to the previous three months.

"The street doesn't have a lot of patience. They see you spending billions of dollars and they want to see a pickup in revenue of that amount," said Daniel Morgan, senior portfolio manager at Synovus Trust, which holds shares in Microsoft.

"If these companies do not hit it out of the ballpark and are far better than the estimates then they are going to be knocked back," he added.

Although the overall growth of Azure has decelerated, AI services contributed a greater share to the revenue increase in the June quarter, accounting for 8 percentage points, compared to 7 percentage points in the preceding quarter.

The company does not disclose the specific revenue figures for Azure, which is well-positioned to benefit from the surging interest in AI technologies. CEO Satya Nadella reported that Azure AI is now utilized by over 60,000 customers, reflecting an almost 60% year-on-year increase, with the average expenditure per customer also on the rise.

Nadella has advocated for a comprehensive integration of AI across the company's offerings, incorporating it into nearly all products, from the Bing search engine to productivity applications like Word. Significant portions of these initiatives have been supported by technology from OpenAI, in which Microsoft has invested approximately $13 billion, including the 365 Copilot assistant designed for enterprises.

The productivity segment, which includes the Office suite, LinkedIn, and 365 Copilot, experienced an 11% growth, surpassing the anticipated 10%. Revenue from the Intelligent Cloud division, which encompasses the Azure cloud-computing platform, increased by 19% to $28.5 billion in the fourth quarter, although it fell short of analysts' expectations of $28.68 billion, according to LSEG data.

Microsoft, regarded as a key indicator for the technology sector due to its extensive business operations, reported a total revenue increase of 15% to $64.7 billion in the fourth quarter, exceeding analysts' projections of $64.39 billion, as per LSEG data.

The revenue generated from the personal computing sector, encompassing Windows and devices like Xbox and Surface computers, experienced a 14% increase. This growth can be attributed to the stabilization observed in personal computer sales. As per the research firm IDC, the PC market witnessed growth for the second consecutive quarter during the April-June period.
