Trian Q1 2026: Peltz's 8-Stock Activist Book

Trian Fund Management, the activist firm run by Nelson Peltz, reported a $3.86B U.S. equity book for the quarter ended March 31, 2026 (Form 13F-HR, accession 0001345471-26-000026, filed 2026-05-15) — and it is about as concentrated as a 13F gets. Trian holds just eight positions, and three of them account for roughly 86% of the entire book. This is activism expressed through a tiny number of very large, very deliberate stakes.

The dominant holding is asset manager Janus Henderson at 42.41% of the book — a position in which Peltz is the largest shareholder and an engaged activist. Next is GE Aerospace (GE) at 29.63%, a legacy of Trian's long involvement with the former General Electric, and Solventum (SOLV) at 13.93%, the healthcare business spun off from 3M.

The book was essentially static on the quarter — Trian held all of its major positions roughly flat, the low-turnover signature of an activist that builds a stake and engages over years rather than trading.

Activism through concentration

After Janus Henderson, GE Aerospace, and Solventum come Ferguson (FERG) at 6.57% and Wendy's (WEN) at 5.48% — the latter a long-standing Peltz holding where Trian has had board representation.

The structure is the strategy. By concentrating capital in a handful of companies, Trian can take large enough stakes to win board seats and push for operational, financial, and strategic changes. There is no long tail here — every position is a campaign or a long-term engagement, which is why the top three names dominate the book so completely.

A static, conviction-weighted book

With all major positions held roughly flat, the quarter offered little trading to interpret — which is itself the point. Activist engagements unfold over years, not quarters, so a stable book reflects ongoing campaigns rather than indecision.

The concentration in Janus Henderson, GE Aerospace, and Solventum shows where Trian's energy is focused: an asset manager it is actively pushing, an aerospace franchise it helped reshape, and a recent spinoff with restructuring potential. Each is a multi-year story.

What it means for 13F readers

Trian is among the clearest examples of activist concentration in 13F data. Because it holds so few names and trades so rarely, the filing is less about quarterly moves and more about which companies Peltz has chosen to engage. The dominance of Janus Henderson and GE Aerospace tells you exactly where the firm's influence is concentrated.
