MSFT Earnings Preview: Azure and AI Capex in Focus

Microsoft Earnings Preview: Can Azure Justify a Near $4 Trillion Valuation?

By: Mike Butler

• Microsoft stock has climbed about 36% since its last earnings report on July 29, pushing the market cap to roughly $3.96 trillion and putting MSFT within about 4% of its 52-week high of $553.72.
• Analysts expect fiscal Q1 EPS of $4.71, up about 14% from $4.13 a year ago, on revenue of roughly $90.6 billion, which sits inside Microsoft’s own guidance range of $89.85 billion to $90.95 billion.
• Azure is guided to grow 44% to 45% in constant currency after accelerating to 43% last quarter, and commercial remaining performance obligation (RPO) stood at a record $678 billion, up 84% year over year.
• Microsoft has guided capital expenditures above $50 billion for the quarter, and the central debate heading into the print is whether AI spending is converting into revenue fast enough to protect margins.
• Options are pricing in a move of roughly 5% in either direction, but MSFT moved 13.4% after its last report against an implied move of 6.7%.

Microsoft Earnings Preview - October 2026

Microsoft (NASDAQ: MSFT) reports fiscal first quarter 2027 results on Wednesday, October 28, after the close. The stock closed Monday at $532.60 with a 52-week range of $349.20 to $553.72. That low came in late June, and shares have rallied sharply since Microsoft’s July report, when Azure growth accelerated and the stock jumped more than 13% the next day. At roughly 29.7 times trailing earnings, MSFT trades below its five-year median multiple of about 33, but the move has left little room for disappointment

The implied volatility setup is moderate by earnings standards. The options market is pricing in a move of about $26, or roughly 5% of the notional value of the stock, which would put the expected range near $505 to $560 and would take MSFT through its 52-week high on the upside. History says to respect the tails. MSFT’s actual move exceeded the implied move in four of the last eight reports, including a 16% surge in April 2025 and a 13.4% jump last July. What's interesting is that the December 2026 cycle still has about 2x more implied volatility on a notional level, with a +-$46 implied range, so there is still some implied volatility priced in through the end of the year.

Microsoft Azure Growth and the $678 Billion Backlog

Azure remains the engine of the story. Microsoft’s cloud platform grew 43% in fiscal Q4 and crossed $100 billion in annual revenue for the first time, and management has guided to 44% to 45% growth this quarter. Intelligent Cloud revenue is guided to $40.95 billion to $41.25 billion, up 33% to 34%. One wrinkle to watch: Microsoft re-segmented its reporting in September, so Azure growth is now measured under an updated definition.

The backlog is the other headline number. Commercial RPO, the contracted revenue not yet recognized, hit $678 billion last quarter. Excluding OpenAI, it still grew 25%, which matters because concentration risk with OpenAI has been a persistent concern since early this year. Management has also said repeatedly that demand continues to exceed available capacity, so Azure growth is a function of how fast Microsoft can bring GPUs and data centers online.

Microsoft Capex: Is the AI Spending Paying Off?

Capital spending is where the bull and bear debates collide. Microsoft spent $41 billion on capex in fiscal Q4, roughly two thirds on short-lived assets like GPUs and CPUs, and has guided to more than $50 billion this quarter. Calendar 2026 capex is expected to land near $175 billion. Heavy depreciation has already pressured margins: gross margin slipped to 67.6% in fiscal Q3, the lowest since 2022, and cloud gross margin was 65% last quarter. Microsoft still guided operating margin roughly flat year over year, so any slippage there will draw attention.

The macro backdrop adds pressure. AI-linked stocks sold off on October 8 after a report that OpenAI’s revenue was lower than expected, and again on October 22, when MSFT fell 2.2%. Anthropic filed for its IPO on October 26, and Meta has outlined up to $95 billion in equity financing, keeping the question of how the AI buildout gets funded front and center.

Bullish Case for Microsoft Earnings

The bull case starts with momentum in estimates and demand. Analysts have nudged revenue estimates higher by about 1% over the past three months, with the biggest upward revisions concentrated in Intelligent Cloud, and Microsoft has a track record of beating on EPS, including a nearly 12% surprise last quarter ($4.74 versus $4.24). Microsoft 365 Copilot passed 30 million paid seats, up from 20 million one quarter earlier, with net seat additions more than doubling. Management is also adding usage-based billing for Copilot products, which could widen monetization. Sentiment on the Street is constructive: 43 of 49 analysts rate MSFT a Buy, the consensus price target is about $592, and Oppenheimer, Scotiabank, and Truist all lifted targets this week, with two of them going to $625. Bulls also point to Microsoft’s diversified AI exposure, including its roughly 27% stake in OpenAI and a relationship with Anthropic that includes both an investment and a large Azure commitment. A beat-and-raise on Azure with stable margins would give the stock a path through $553.72 into price discovery.

Bearish Case for Microsoft Earnings

Bears argue that MSFT is priced for a clean beat. The stock is up about 36% in three months, and the technical picture is less convincing than the headline: MSFT has stalled three times near $546, and momentum indicators have shown bearish divergence. The January report is the cautionary tale, when shares fell as much as 12% intraday after capex jumped 66% and Microsoft disclosed that roughly 45% of its RPO was tied to OpenAI. This time, more than $50 billion in quarterly capex, falling gross margins, and nervousness about AI financing could easily outweigh a strong Azure print. Weakness outside the cloud is another drag, with More Personal Computing revenue down 4% and Xbox content and services down 5% in the last report. If Azure comes in at the low end of guidance or management signals higher spending without a matching revenue lift, a stock sitting near its highs has a long way to fall.
