AI Holders Summary · Q1 2026

Kadant Inc's (KAI) two dominant owners both cut their positions this quarter — and with two firms controlling roughly 91% of the $366.3 million spread across 26 institutional holders, that is most of the story. Wasatch Advisors, the dominant holder at 74.5% of institutional value, reduced its stake by 16.4% in shares (a genuine $53.4 million reduction, from 1,038,548 to 868,696 shares). Riverbridge Partners, the second-largest holder at 16.7%, cut even more sharply in percentage terms — down 22.9% in shares (a real $18.1 million reduction). Together these two moves account for the overwhelming majority of this quarter's selling activity. On a much smaller scale, Linden Thomas Advisory Services added to its position (+690 shares, a genuine $216,819 buy), while Fifth Third Wealth Advisors and Wealth Enhancement Advisory Services opened new, modest stakes.

Two holders, 91% of the book, both selling

Wasatch Advisors alone holds $273.0 million, 74.5% of all tracked institutional value — and this quarter its share count fell from 1,038,548 to 868,696, a 16.4% reduction representing a genuine $53.4 million real sale. Riverbridge Partners, the second-largest holder at 16.7% of the book, cut even more sharply in percentage terms: shares down 22.9%, from 252,230 to 194,573, a real $18.1 million reduction. With these two firms controlling roughly 91% of institutional ownership, their simultaneous trimming is the dominant story in this stock's ownership data this quarter — not a one-off from a minor holder, but the two largest, most influential owners moving in the same direction at once.
