The Dutch lithography giant reported third-quarter net sales of 11.662 billion euros and net income of 4.960 billion euros, with a gross margin of 57.5 percent and basic earnings per share of 12.95 euros.

At its Gemini at Work 2026 event on October 8, 2026, Google Cloud CEO Thomas Kurian introduced the Gemini agent — which Google describes as "a single, universal agent for work" that answers questions, handles knowledge work, creates media, and writes and runs code. The agent runs on the web, iOS, Android, Windows, Mac, and the command line; inside Google Workspace, Microsoft 365, and Slack; and headlessly inside third-party applications. The pitch: one interface, one API, and an objective instead of step-by-step instructions.
