Four of the ten (Uber, Tyler Technologies, BNY Mellon, Berkshire Hathaway) belong to the group of 84 firms whose 10-Q filings were scored in addition to their 8-Ks, which mechanically raises their scores (Section~\ref{subsec:corpus}). For each firm the table reports its ticker, company name, GICS sector, and average AI-adoption score. The ranking features enterprise-technology and software firms alongside an algorithm-centric platform and data-intensive financials, and it is not confined to the Information Technology sector.}19\end{table}20
