Portfolio Overview

Sherborne Investors Management LP’s reported 13F portfolio as of 2025-12-31 is extremely concentrated and modest in scale for an institutional filing: total reported 13F assets of $382.85 million, comprised of a single holding. The portfolio declined by 1.1% vs. the prior quarter (from $387.27M to $382.85M), with no reported trading activity (no new, sold, increased, or reduced stakes). The lack of turnover in the quarter and the single-security structure indicate a highly...

Key Holdings

The sole holding is Navient Corp (ticker NAVI), valued at $382.85 million and representing 29.45 million shares — 100% of the reported portfolio. The implied per‑share valuation from the filing is approximately $13.00 per share ($382.85M / 29.45M shares). Because NAVI accounts for the entire 13F portfolio, the filing shows that the filer’s public-equity exposure reported to the SEC is entirely tied to the performance and specific risk factors affecting this single issuer.

Sector Allocation

Sector concentration is absolute: 100% of the portfolio is allocated to “Financial Services” (Navient). There are no other sector exposures reported in this 13F. This represents a clear single-sector, single-name tilt and therefore subjects the portfolio to both sector-specific and issuer-specific risks (credit, interest-rate sensitivity, regulatory and litigation risk that typically affect financials and loan servicers).
