Amazon Slumps as Massive AI Spending and Margin Pressure Overshadow AWS Reacceleration

AI Infrastructure Costs Weigh on Sentiment

Amazon shares dropped to $256.67 on Thursday morning, representing a 2.76% underperformance relative to the S&P 500, which edged up 0.34%. The move comes on the heels of the company's first-quarter earnings report, which initially appeared to be a blowout success but revealed significant underlying pressures upon closer inspection. While net sales of $181.5 billion comfortably beat the $177.3 billion consensus, the market's focus shifted rapidly to the staggering cost of maintaining Amazon's lead in the artificial intelligence race.

Capital expenditures for the quarter hit $44.2 billion, a 77% increase year-over-year. This massive investment in data centers and custom silicon caused free cash flow to collapse to just $1.2 billion on a trailing twelve-month basis, down 95% from the $26 billion reported in the same period last year. Analysts noted a "regime change" in Amazon’s funding strategy, as the company issued $53.4 billion in long-term debt during the quarter to fund its AI ambitions—a stark contrast to its historical reliance on operating cash flow.

The Anthropic Distortion and Adjusted EPS

Investor skepticism was further fueled by the composition of Amazon's bottom-line beat. The company reported diluted earnings per share (EPS) of $2.78, far exceeding the $1.64 analysts had modeled. However, this figure included a $16.8 billion pre-tax gain from Amazon's investment in AI startup Anthropic. Excluding this one-time benefit, adjusted EPS came in at approximately $1.61, a slight miss against the $1.62 to $1.67 range expected by Wall Street. This "quality of earnings" concern, combined with the capital intensity of the business, has led some institutional investors to trim positions despite the top-line growth.

AWS Reacceleration vs. Margin Guidance

The primary bright spot in the report was Amazon Web Services (AWS), which saw revenue grow 28% to $37.6 billion. This represents the fastest growth rate for the cloud segment in 15 quarters, suggesting that Amazon's investments in generative AI and custom chips like Trainium are beginning to capture significant enterprise demand. CEO Andy Jassy highlighted a record AWS backlog of $364 billion, up from $244 billion in the prior quarter.

However, this cloud momentum was tempered by cautious guidance for the second quarter. Amazon expects operating income between $20 billion and $24 billion. The midpoint of $22 billion implies a deceleration in profit growth compared to the 30% jump seen in Q1, as the company prepares for a $1 billion cost increase related to its Project Kuiper satellite launch and continued depreciation from its heavy infrastructure build-out.

Forward Outlook

Looking ahead, Amazon remains a central play in the AI infrastructure cycle, but the stock's immediate path may be dictated by its ability to prove that these multi-billion dollar investments can translate into sustained margin expansion. With 48 million shares traded by midday, the high volume suggests a significant repositioning by investors who are now demanding more discipline in capital allocation. While Bank of America raised its price target to $310 following the report, the intraday price action suggests the market is currently prioritizing cash flow stability over long-term cloud potential.
