Microsoft Corporation (NASDAQ:MSFT) shares continued their upward momentum on Monday, with the stock indicated up 2.1% at $474.40 in premarket trading as of 07:47 EDT, ahead of the official Nasdaq session open. This follows a remarkable 21.8% surge over the previous week, culminating in a record-breaking single-day gain on Thursday that added approximately $450 billion to the company's market capitalization.
The rally was fueled by the company's impressive fiscal fourth-quarter earnings report, which revealed a commercial remaining performance obligation (RPO) backlog of $678 billion—an 84% increase year-over-year. This backlog, which represents contracted future revenue, is now driven primarily by non-frontier-model clients, indicating that Microsoft's growth is expanding well beyond its partnership with OpenAI.
Approximately 30% of the backlog, or about $203.4 billion, is expected to be recognized as revenue over the next twelve months. This figure is 1.16 times Microsoft's updated capital expenditure forecast for calendar 2026, which is approximately $175 billion. While this ratio underscores revenue predictability rather than direct return on investment, it reflects the company's strong contract visibility.
Microsoft's capital spending plans have been a point of focus. The $175 billion figure for 2026 is lower than some expectations, but the company clarified that this is due to a lease-accounting adjustment, not a reduction in investment. In fact, fiscal Q1 2027 capital expenditures are expected to exceed $50 billion, and the company projects continued increases in fiscal 2027.
The earnings report showcased robust operational performance. Revenue came in at $90.0 billion, beating the Wall Street consensus of $87.62 billion by 2.7%. Adjusted earnings per share, excluding OpenAI-related impacts, surged to $4.74, well above the expected $4.24. Azure, Microsoft's cloud computing platform, was the standout performer with 43% sales growth, surpassing the estimated 39.98%.
Looking ahead, Microsoft's fiscal Q1 2027 revenue guidance of $90.4 billion (midpoint) also exceeded expectations, and the company projected Azure growth of 45% at constant currency, compared to the 40.92% consensus. Chief Financial Officer Amy Hood noted that demand "continues to exceed available supply," echoing the sentiment of portfolio manager Dave Wagner of Aptus Capital Advisors, who said Azure is "staying right there in the race."
However, the rapid expansion has impacted cash flow. While operating cash flow rose 30% to $55.4 billion in the quarter, free cash flow declined 23% to $19.6 billion due to a 69% increase in quarterly capital spending to $41.0 billion. Gross margin also contracted to 67% from the previous year. Additionally, the company disclosed $329.1 billion in uncommenced data-center leases, indicating significant future investment.
Beyond the numbers, Microsoft continues to expand its enterprise footprint. ArcelorMittal SA (NYSE:MT) announced on Monday that Azure would remain its primary cloud platform, and the company plans to adopt Microsoft Fabric, Purview, and Foundry. The number of paid Microsoft 365 Copilot seats surpassed 30 million, up from 20 million previously, signaling strong adoption of the company's AI-powered productivity tools.
Comparisons with competitors highlight Microsoft's leading position in cloud backlog-to-capex ratio. While Alphabet's Google Cloud grew 82% and Amazon's AWS grew 37% in their latest quarters, Microsoft's Azure growth of 43% is more mature but still accelerating. Microsoft's backlog-to-capex ratio of 3.9 times (using the $678 billion RPO and $175 billion capex plan) exceeds Alphabet's 2.6 times and Amazon's 2.3 times, though the figures are not directly comparable due to differing scopes.
The stock's performance has been exceptional, with a 21.75% gain over the July 24-31 period, compared to a 1.59% rise in the Nasdaq Composite. Trading volume on July 31 was 60.85 million shares, 1.5 times the 65-day average. This week brings key economic data, including manufacturing figures on Monday, services data on Wednesday, and July payroll numbers on Friday, which could influence market sentiment.
Risks remain, including the decline in free cash flow, rising capital expenditures, and a 7% drop in Windows OEM and Devices revenue, as well as a 10% fall in Xbox content and services revenue. Nonetheless, Microsoft's strong backlog and Azure momentum suggest continued growth ahead, even as the company navigates the complexities of scaling its AI infrastructure.
