Amazon and Meta, two heavyweights of the tech industry, recently delivered quarterly earnings reports that have sparked significant market reactions. While Amazon impressed Wall Street with robust revenue growth, particularly in its cloud and ad segments, Meta faced criticism for ballooning expenses that have raised concerns about its future profitability. Here’s a detailed look at what's happening under the hood of these companies and what it means for investors.

Amazon: A Clear Winner with AWS Leading the Charge

Amazon has emerged as a beacon of stability and growth in the tech sector. Its latest earnings revealed total net sales up 17% year-over-year, a solid performance complemented by even stronger operating income growth of 30%. These numbers signal that Amazon is effectively managing costs while boosting revenue.

AWS Keeps Amazon Soaring

Amazon Web Services (AWS) continues to be the linchpin of the company’s dominance. AWS revenue surged 28% year-over-year to $37.59 billion, marking its fastest growth in over three years. Wall Street had predicted 26% growth in the segment, but AWS easily outpaced those estimates. This performance is significant, as AWS remains Amazon's most important and profitable division.

If the growth trajectory continues, analysts believe that AWS could reaccelerate to 30%-plus year-over-year revenue growth in coming quarters—a significant development given that it anchors Amazon’s long-term value proposition. The positive surprise in AWS revenue has also given Amazon the breathing room to justify high capital expenditures. Unlike Meta, Amazon’s heavy spending is viewed through a favorable lens because it is directly linked to AWS’s expanding market share and profitability.

A Thriving Advertising Business

In addition to AWS, Amazon’s advertising segment quietly continues to shine. Advertising revenue climbed 24% year-over-year to $17.24 billion, exceeding Wall Street estimates of 21.2% growth. The advertising arm is now a critical pillar of Amazon’s growth narrative, alongside AWS and e-commerce, as it accounts for a growing share of overall profitability.

While Amazon has long been a capex-heavy business, its disciplined approach to areas like sales and marketing costs—up just 6% versus the 17% revenue growth—highlights its operational efficiency. It's no surprise then that Amazon’s stock moved to an all-time high in after-hours trading.

Meta: Cost Concerns Overshadow Revenue Growth

On the other side of the spectrum is Meta, whose earnings showcase both strong top-line growth and troubling cost management challenges. Revenue rose 33% year-over-year, making Meta one of the fastest-growing tech players among the so-called “Magnificent Seven,” outside of Nvidia. Yet, this impressive growth has been clouded by surging costs.

Rising Expenses Raise Red Flags

Meta’s total costs and expenses jumped 35% year-over-year, surpassing revenue growth—a concerning trend for any business. R&D expenses, in particular, ballooned by 46%, in stark contrast to the 33% rise in revenue. Similarly, the cost of revenue climbed 35%, further eroding profitability margins.

Operating income grew 30%, which, while solid, fell short of the leverage investors typically seek in high-growth companies. For a company like Meta, where expectations are sky-high, these numbers fell short of earning stellar marks from cautious analysts.

Daily Active User Drop and Unjustified Capex

Another sore spot for Meta was its decline in daily active users (DAPs), which fell from 3.62 billion in the previous quarter to 3.56 billion—an unexpected drop attributed to geopolitical issues such as restricted WhatsApp access in Russia and the Israel-Hamas conflict affecting user access in certain regions. Nonetheless, Wall Street wasn’t forgiving, as DAP growth is considered a key health metric for Meta.

Perhaps the most alarming development in Meta’s report was its capital expenditure guidance. The company increased its capex outlook to a staggering $125–$145 billion for the year, raising questions about its cost discipline. Investors are left wondering why such eye-watering sums are necessary and where the ROI will come from. Meta has repeatedly stated its need to invest heavily in AI and future technologies, but these explanations have yet to comfort markets. Without clear explanations from CEO Mark Zuckerberg, skepticism will likely persist.

Comparing the Two Giants

The difference in market reaction to Amazon and Meta partly boils down to the clarity of their spending strategies. Amazon pairs its high capex with undeniably strong value-building in AWS and advertising. Investors see a clear connection between rising investments and measurable revenue growth. In contrast, Meta’s skyrocketing expenses appear less targeted. The company is spending heavily on AI and infrastructure, but whether these efforts will lead to meaningful long-term growth is up for debate.

Additionally, Meta’s ongoing battle with rising costs makes the profitability picture murky. If spending continues to outpace revenue growth, the downward pressure on net income could persist, putting the stock at risk of further declines.

What It Means for Investors

For long-term investors, the two companies highlight contrasting strategies in the tech world. Amazon remains a textbook example of leveraging its business model efficiently, with AWS and advertising supporting consistent returns. Its forward P/E ratio of approximately 33 paints it as a reasonably priced growth stock with substantial upside potential.

Meta, while still a dominant force in social media and digital advertising, is grappling with cost management challenges that could overshadow its high revenue growth. The critical question for investors is whether Zuckerberg’s aggressive spending will translate to long-term gains or continue to weigh on the company’s profitability.

What’s Next?

Looking ahead, Amazon seems poised to build on its momentum, especially if AWS revenue growth accelerates into the 30% range. Meanwhile, Meta needs to clarify how it plans to control costs and better communicate the rationale for its high capex. Until it does so, fears of declining margins and an unclear ROI on its AI and infrastructure projects will persist.

In a market that punishes ambiguity and rewards focused growth, Amazon has shown how to play the game. Meta, by contrast, will need to regain investor trust in its spending strategy to reclaim its shine.
