About Glenn Greenberg

Glenn Greenberg co-founded Chieftain Capital in 1984 alongside John Shapiro, building a reputation for deep-fundamental, highly concentrated long-only equity work before launching Brave Warrior Advisors in 2010. The style is straightforward: identify businesses with durable competitive positions and patient capital allocation, hold them in size, and turn over the portfolio infrequently — a discipline reflected in Brave Warrior's current 13F, where five names account for roughly half of disclosed U.S. long equity. With 36 positions across a $4.0B book, the portfolio is genuinely concentrated by institutional standards, and the top holdings — distribution, consumer finance, contract research, managed care, and auto retail — suggest a preference for businesses with recurring revenue or structural pricing power rather than thematic momentum. The 13F captures the strategy reasonably well because derivatives and short selling are not central to the public record here; what you see is close to what drives performance. The latticework backtest shows modest negative excess return versus SPY over twelve years, a reminder that concentration and quality bias do not automatically translate to index-beating results in all regimes.

2026Q1 brief

Glenn Greenberg's Brave Warrior Advisors ($4.04B, 36 positions) made ICLR (Icon PLC) its single most consequential move in 2026Q1, initiating a brand-new position that immediately became the third-largest holding at 8.2% of the portfolio — a textbook Greenberg-style conviction entry into a competitively advantaged CRO business under pressure. The top-five concentration sits at 46.8%, anchored by SNX (12.8%) and OMF (10.2%), underscoring his characteristically narrow, high-conviction approach. The ICLR bet is notably contrarian: CRO stocks have faced macro headwinds from biotech funding tightness, suggesting Greenberg sees a valuation dislocation. Elsewhere, he trimmed MPLX by 27% (still a meaningful 4.6% position) and cut HCA by 66%, the latter a near-exit that signals fading conviction in for-profit hospital operators. The exits of USB, V, and SPGI — all previously sub-0.02% residuals — are routine housekeeping. The new toe-hold positions in ARES and APO (both under 0.02%) are worth watching: watch whether alternative asset managers get sized up meaningfully in the next filing.
