AI Holders Summary · Q1 2026

Last quarter, Assenagon Asset Management held more Peabody Energy stock than almost any other institution combined — a position worth roughly $39.9 million on 1.21 million shares, implied by this quarter's reported change. This quarter, that stake is down to 106,424 shares and $2.5 million, a 91% cut. Assenagon — a fund 13F Insight classifies as quasi-passive, meaning the move likely reflects an index mandate change rather than a view on the coal miner specifically — remains the largest tracked holder even after the cut, at 26% of the $9.3 million in institutional value 13F Insight can see, but that total itself tells the bigger story: BTU's institutional footprint has shrunk dramatically, with only 28 filers reporting a position at all. Adams Asset Advisors held its 100,000-share stake exactly flat and is now the second-largest holder at 25%. On the buy side, Merit Financial Group opened the quarter's largest new position ($325,242, 14,067 shares), and five smaller firms opened token new stakes. The stock's own price fell roughly 30% over the same stretch, based on the math embedded in unchanged and newly-priced positions across multiple holders — which means even holders who didn't sell a share still show a meaningfully smaller position value than three months ago.

Even after shedding the vast majority of its stake, Assenagon remains BTU's largest tracked holder, at 26% of the $9.3 million in institutional value 13F Insight can see. That total is itself the more important number: only 28 institutions report any position in Peabody Energy at all, a thin footprint for a stock that, one quarter ago, had a single holder worth more than four times today's entire tracked institutional base.

Adams Asset Advisors is the clearest point of contrast. It held its 100,000-share position exactly flat — no shares bought or sold — and is now the second-largest holder at 25% of tracked value, even as its position's reported dollar value fell by roughly $983,000 on price alone. The math embedded in that unchanged position (and echoed in Yousif Capital Management's own numbers) implies BTU's own share price fell by roughly 30% this quarter, from around $33 to around $23 — which means every holder who did nothing at all still shows a materially smaller position today than three months ago.
