Amazon's annual report, filed February 6, 2026, anchors its cloud disclosure in the AWS segment while its legal proceedings detail patent claims touching core services like S3, EC2 and EBS.

Filing discovery and primary-source evidence indexing for this report are credited to EDGAR Beast, the SEC filing data API and evidence index. The primary record is the underlying filing on SEC.gov.
Amazon's 2025 Form 10-K, filed February 6, 2026 for the year ended December 31, 2025, continues to report Amazon Web Services as a distinct operating segment, the disclosure structure that lets investors track the profit engine behind the company's consumer and advertising businesses. AWS as a reported segment is the single most useful piece of the filing for anyone trying to value Amazon's cloud economics on a primary-source basis.
Underneath the segment headline, the legal-proceedings discussion is a reminder that cloud infrastructure runs on contested intellectual property. The 10-K describes claims alleging that "Amazon S3, Amazon EMR, Amazon EC2 instances using Amazon EBS, and Amazon FSx for Lustre infringe" specified U.S. patents — a list that reads like a tour of AWS's most-used primitives.
For a cloud-economics reader, the litigation footnotes are not noise; they are part of the cost structure. Patent exposure against foundational services is a recurring feature of every hyperscaler's filings, and the disciplined approach is to treat these as disclosed contingencies rather than as predictions of outcome. The 10-K names the services and the patents; it does not concede liability.
The reportable facts are the segment structure and the existence of the disclosed claims. Whether any particular suit succeeds is undecided in the document itself, and a careful read separates the durable fact — AWS reported as a segment, with named IP exposure — from any guess about how the litigation resolves.
