4 "Magnificent Seven" Companies Are About to Report Earnings -- All on the Same Day. Here's What to Watch.

As earnings season continues to unfold, Wednesday is arguably the most important day yet. After market close, we'll get earnings reports from four of the "Magnificent Seven" companies -- Alphabet (NASDAQ: GOOG)(NASDAQ: GOOGL), Amazon (NASDAQ: AMZN), Microsoft (NASDAQ: MSFT), and Meta Platforms (NASDAQ: META). With all of these companies' market capitalizations measured in the trillions of dollars, their reports could move the market.

Interestingly, even though each of these businesses is significantly different from the others, investors will likely be watching some of the same key items across all four companies' reports. Indeed, probably the most important figure for all four companies is the same: revenue growth. If any of these companies fails to meet Wall Street's expectations for top-line growth, even as their capital expenditures soar, investors could question the artificial intelligence (AI) growth narrative that all four of these companies are pushing. In short, these companies need to show that their accelerating spend on an AI build-out is paying off in impressive top-line performance.

And this brings us to the other part of the equation: operating earnings. To what extent is this massive investment cycle weighing on earnings growth in the form of higher depreciation expenses? If earnings growth is suppressed too much by the costs associated with these companies' big spending plans, it could spook investors.

A focus on revenue growth

Each company is coming off solid double-digit revenue growth in its most recent quarter. But the bar Wednesday's reports must clear varies notably across the group.

Alphabet posted 18% year-over-year growth in the fourth quarter, helped by Google Cloud's 48% jump to $17.7 billion. And management said it expects a foreign exchange tailwind in Q1, which could help maintain momentum. Also worth noting, Alphabet's cloud backlog ended 2025 at $240 billion, up 55% sequentially.

In its fiscal second quarter of 2026 (the period ended Dec. 31, 2025), Microsoft's revenue rose 17%, with Azure growing 39%. But its fiscal Q3 guidance points to modest deceleration: revenue of $80.65 billion to $81.75 billion -- about 16% growth at the midpoint -- with Azure guided to 37% to 38% in constant currency. But investors are probably hoping the figure actually accelerates, coming in at 40% or better.

Meta's fourth-quarter revenue rose 24% to $59.9 billion. But even more notable is the company's first-quarter guidance of $53.5 billion to $56.5 billion. Against the year-ago period's $42.3 billion in revenue, the midpoint implies an impressive 30% year-over-year growth rate.

And, finally, Amazon's fourth-quarter revenue rose 14% to $213.4 billion. The quarter's standout figure, however, was AWS revenue (Amazon's cloud computing business), which climbed 24% to $35.6 billion -- its fastest growth in 13 quarters. Management's first-quarter guidance of $173.5 billion to $178.5 billion implies 11% to 15% growth. But given the stock's approximately 30% gain over the last 30 days, investors are probably looking for actual revenue at or above that guidance range, fueled by a further acceleration in AWS.

The capital-expenditure overhang

These four companies' 2026 capital expenditure plans are mind-boggling. Indeed, when combined, these four companies could spend more than $600 billion on capital expenditures this year.

Alphabet plans to spend $175 billion to $185 billion on capital expenditures in 2026 -- roughly double its $91.4 billion in 2025; Amazon forecast roughly $200 billion this year (versus about $131.8 billion in 2025); Meta is guiding for $115 billion to $135 billion (against $72.2 billion last year); and Microsoft hasn't provided a full-year figure, but its first-half fiscal 2026 capital expenditures of $72.4 billion implies something in the neighborhood of $130 billion for the fiscal year.

But such heavy spending eventually flows through to depreciation. To this end, Alphabet chief financial officer Anat Ashkenazi told investors on the company's fourth-quarter earnings call that "given the increase in our CapEx investments in recent years, we expect the growth rate in 2026 depreciation to accelerate in Q1, and meaningfully increase for the full year."

Similar pressure is building across the group.

Investors will be looking for evidence that each company can absorb this cost ramp while still growing operating income.

Going into these companies' reports, we have some clues about what to expect from operating income.

Meta said it expects 2026 operating income "above" 2025 levels despite the spending step-up. And Amazon's first-quarter operating income guidance of $16.5 billion to $21.5 billion straddles last year's $18.4 billion, but it also absorbs about $1 billion of new costs tied to its Amazon Leo satellite project.

All four companies report after market close on Wednesday. With market caps measured in the trillions and AI infrastructure spending at record levels, the stakes for each report are unusually high.

Whatever the results, investors should buckle up: post-earnings volatility could be significant.
