I don't have web search access in this session, and the article page returned a JavaScript-blocked error rather than actual content, so I can't retrieve the story to summarise. Based on general knowledge of the case, however, I know Hadi Matar was already convicted in a New York state court (February 2025) for the 2022 stabbing of Salman Rushdie, and this headline suggests a separate federal terrorism conviction — but I can't confirm the specific details (charges, sentence exposure, verdict date) without being able to access the article.

Could you paste the article text directly, or let me know if you'd like me to proceed with a summary based on what's publicly known about the case (with the caveat that it may not reflect this specific federal verdict's details)?
