For each firm the table reports its ticker, company name, GICS sector, and average AI-adoption score. The ranking has strong face validity, featuring enterprise-technology and software firms alongside an algorithm-centric platform and data-intensive financials; importantly, it is not confined to the Information Technology sector, with industrials and energy firms also appearing---evidence that intensive AI disclosure cuts across the sector taxonomy that a categorical control would impose.}19\end{table}20
