Microsoft Earnings Preview: Can Azure Justify a $220 Billion Capex Bill?

• Microsoft (NASDAQ: MSFT) reports fiscal fourth-quarter 2026 earnings on July 29, its final quarter of the fiscal year, which means management must also guide for fiscal 2027, the number the whole AI trade is waiting on.

• Analysts are forecasting EPS of roughly $4.21 to $4.24 on revenue near $87.7 billion, representing year-over-year growth of about 15% and 15%, respectively, extending a streak of four straight quarterly beats.
• Azure grew 40% last quarter (39% in constant currency), and whether that number holds above 35% or accelerates further will matter more to the stock than the headline EPS print.
• MSFT trades roughly 29% below its 52-week high of $555.45, at about 20.6 times forward earnings, among the cheapest multiples the stock has carried in years despite still posting double-digit revenue growth.
• The central tension heading into Wednesday is capital expenditures. Microsoft already guided to $190 billion for calendar 2026, up 61% from 2025, and analysts expect FY2027 guidance to land in the 20% to 30% growth range, or roughly $220 billion.

Microsoft Earnings Preview - July 2026

Microsoft has had a rough stretch by its own standards. Shares sit at $389.51 as of July 27, down about 25.7% over the past year and well off the 52-week high of $555.45 set last summer. That drawdown has happened even as the underlying business keeps growing at a clip most large-cap companies would envy. Last quarter, Microsoft beat on both the top and bottom lines, with revenue of $82.9 billion (up 18% year over year) and adjusted EPS of $4.27 versus the $4.06 Street estimate. Azure and other cloud services grew 40% in constant currency, and Copilot paid seats surpassed 20 million, up more than 250% year over year. None of that stopped the stock from sliding, because investors have been fixated on one line item: capex.

Wednesday's report closes out fiscal 2026, so Microsoft has to say something concrete about fiscal 2027 spending. Consensus sits at revenue of roughly $87.7 billion (up 14.7% year over year) and EPS of about $4.22, up 15.6%. Those numbers are almost secondary. The real question is whether CFO Amy Hood's capex guidance comes in around $220 billion, which would represent 20% to 30% growth and would read as disciplined relative to Azure's own growth rate, or whether it runs hotter and reinforces fears that the spending machine has no ceiling.

MSFT implied volatility is somewhat elevated ahead of the announcement, with a notional value implied move of 6.5% for this week. Looking further to September 2026, we can see just how much of this implied volatility is baked into a longer term cycle. September's implied move is only +-$44.26, and this week's expected move accounts for 60% of that implied range. I expect all of these implied volatility readings to crush down closer to 35% as that's what we're seeing in the very long term cycles that have many earnings announcements within them.

Azure Growth Is the Headline Number That Matters Most

Azure's growth rate is the single most-watched metric in this report. Microsoft guided last quarter to 39% to 40% Azure growth at constant currency for fiscal Q4, above the 37% consensus at the time. If Azure holds at or above that 39% to 40% range, or reaccelerates further, it reinforces the bull case that AI workloads are translating directly into cloud consumption. If growth slips meaningfully below 35%, it would echo the capex-to-revenue concerns that have already dogged Alphabet this earnings season. Microsoft's commercial bookings and remaining performance obligations, essentially contracted future revenue not yet recognized, will also get scrutiny as a forward-looking signal on whether AI demand is durable or front-loaded.

The $220 Billion Capex Question Heading Into Fiscal 2027

Microsoft's gross margin fell to 67.6% last quarter, its narrowest since 2022, as depreciation from the company's data center buildout mounted. Capital expenditures and finance leases hit $31.9 billion in fiscal Q3, up 49% year over year, and full calendar 2026 capex guidance stands at $190 billion, a 61% jump from 2025. Analysts widely expect Microsoft to guide FY2027 capex growth in the 20% to 30% range on this call, translating to roughly $220 billion. That figure matters because it needs to stay below Azure's own growth rate. If Microsoft's cloud engine can no longer fund its own buildout at a rate faster than spending grows, the market is likely to punish the stock the way it punished other hyperscalers on this same worry. A number that comes in meaningfully hotter than $220 billion, paired with any softening in Azure growth, would be the clearest bear signal available on Wednesday.

Bullish Case for Microsoft Earnings

Bulls point to valuation first. At roughly 20.6 times forward earnings, MSFT trades near its cheapest multiple in years for a company still growing revenue in the high teens. Analyst price targets remain well above the current share price, with an average target near $552 from a group of more than 50 analysts, the majority of whom rate the stock a strong buy, implying substantial upside from current levels. Azure's 39% to 40% growth rate is still one of the fastest in the hyperscaler group, and Copilot's rapid seat growth suggests Microsoft's AI products are finding paying enterprise customers, not just experimental pilots. If capex guidance for FY2027 comes in at or below the 20% to 30% range analysts expect, while Azure growth holds steady or accelerates, bulls argue the stock could see the kind of relief rally that comes from removing the market's single biggest overhang.

Bearish Case for Microsoft Earnings

Bears aren't arguing that Microsoft's cloud business is weak. They're questioning whether spending discipline exists at all. Gross margin has already compressed to its lowest level since 2022, and capex has been running ahead of consensus for multiple quarters straight, including a $31.9 billion figure last quarter against a Street estimate of $34.9 billion that still marked a 49% year-over-year jump. If FY2027 guidance comes in above $220 billion, especially if it's paired with Azure growth decelerating below 35%, the stock could revisit the kind of selloff that hit Alphabet's shares after its own capex disclosure earlier this earnings season. With MSFT already down nearly 30% from its highs, the market has priced in some caution, but a genuinely disappointing capex number, on top of an in-line quarter, is the scenario bears are watching for most closely.
