Amazon Capex Plan Fuels Stock Volatility

Amazon.com Inc. (AMZN) on Feb. 5, 2026 reported Q4 2025 results and unveiled an expansive capital expenditure plan focused on AI and cloud infrastructure. The announcement triggered a multiday market pullback and shifted near-term cash-flow expectations for investors.

Quarter Results and Cash Flow

The company said in a press release that Q4 2025 revenue reached $213.4 billion, up 14% year over year. Net income was $21.2 billion, or $1.95 a share, slightly below the $1.96 consensus estimate.

Amazon Web Services (AWS) posted $35.6 billion in revenue, up 24% year over year excluding foreign exchange effects, with operating income of $12.5 billion. This lifted AWS to a $142 billion annualized run rate, underscoring its continued growth.

Free cash flow for the quarter fell 71% year over year to $11.2 billion, reflecting rising capital expenditures.

For the full year, 2025 revenue rose 12% to $716.9 billion, with net income of $77.7 billion, or $7.17 a share.

Regionally, North America generated $127.1 billion in Q4 revenue, up 10%, with operating income of $11.5 billion. International revenue increased 17% to $50.7 billion, producing $1.0 billion in operating income.

Advertising revenue grew 22% year over year to $21.3 billion. The company reported 1,576,000 full- and part-time employees at the end of the period, about 1% more than a year earlier.

Capex Plan and Market Reaction

Amazon guided roughly $200 billion in capital expenditures for 2026, concentrated in AWS to expand cloud capacity, AI chips, robotics, and satellite projects. Management said the spending aims to deliver strong long-term returns, with Trainium 3 chip supply expected by mid-2026. The chips business has surpassed a $10 billion annualized revenue run rate and is growing at triple-digit percentages year over year.

The capex guidance overshadowed the quarter’s results, prompting a multiday re-pricing that erased about 16% of the company’s market value as investors weighed near-term cash-flow pressure against longer-term opportunity. Some market participants viewed the pullback as a buying opportunity, while others flagged the scale and timing of the spending.

For the first quarter of 2026, Amazon set net sales guidance between $173.5 billion and $178.5 billion, an 11% to 15% increase year over year that includes an estimated 180 basis-point foreign-exchange tailwind. Operating income is projected between $16.5 billion and $21.5 billion, assuming about $1 billion of higher costs related to Amazon Leo.

Investors will monitor whether the company’s heavy investment in infrastructure and chips, supported by the mid-2026 hardware milestone, translates into the stronger cloud economics and returns anticipated in the guidance.
