How to read this report

Every number comes from SEC filings, end-of-day prices and the StocksXray models described on the methodology page. The X-Ray Score ranks each metric against the company's own sector. Fair value blends three models and carries a typical error of about 40%, so treat it as a range. Analyst ratings, price targets and earnings-call summaries are not part of this report.
