Cloud Leads the Way: AWS Fuels Profit Recovery

As a key and profitable division for Amazon, AWS once again drove the company’s overall performance. During Q3, AWS generated US$33.01 billion in revenue, up 20% YoY—significantly exceeding market expectations of US$31.5 billion—and marked the fastest growth since late 2022.

Management stated during the earnings call that surging demand for generative AI and cloud-native enterprise architectures has led to accelerated spending from large customers, while medium and small clients have also gradually resumed “pay-as-you-go” usage. By comparison, Microsoft Azure and Google Cloud posted Q3 growth rates of 29% and 22%, respectively. While AWS did not top the growth chart, it remains the industry leader by revenue scale.

Analysts note that if AWS can sustain a quarterly growth rate above 15%, coupled with the potential scale-up of AI services, Amazon could re-enter a “high-growth, high-profit” cycle, further enhancing profit margins and free cash flow resilience.

Investing in the Future: AI and Infrastructure at the Core

With growth gaining momentum, Amazon significantly increased investments in AI and cloud infrastructure this quarter. CEO Andy Jassy emphasized in his letter to shareholders that the company will continue to focus on three strategic pillars over the coming years: “AI + Cloud + E-commerce logistics.”

These investments include: expanding cloud data centers and compute capacity; introducing new Trainium 2 and Inferentia 3 chips for multi-modal AI applications; improving North American warehousing with faster delivery capabilities; and launching the Amazon Q generative AI platform for developers and businesses, covering use cases such as customer service, content creation, and coding.

Although these initiatives have pushed up capital expenditures and depreciation costs in the short term, management stressed that these are “investments for growth over the next five years,” with gains from AWS, advertising, and subscription services expected to offset the associated financial pressure.

Risks and Challenges: Cash Flow Volatility and Macro Uncertainty

Despite strong results, Amazon still faces several risks. Free cash flow (FCF) over the past 12 months fell to US$14.8 billion, down from US$20.1 billion in the previous quarter, reflecting near-term financial strain from expansion efforts. The company also recognized one-off expenses totaling approximately US$4.3 billion related to legal settlements, severance, and inventory adjustments, which weighed on operating profit. Moreover, persistent inflation, pressure on consumer spending, and intensifying cloud competition remain key challenges. Amazon must continue balancing growth with operational efficiency to sustain long-term resilience.
