OSTERWEIS CAPITAL MANAGEMENT INC
$1.9B in tracked AUM across 277 positions as of Q1 2026.
Last quarter, Osterweis Capital Management held nine convertible notes all maturing within a tight ten-week window — Airbnb, Bentley Systems, Marriott Vacations, Summit Hotel Properties, Cable One, Enphase Energy, Haemonetics, Vail Resorts, and Alarm.com, each dated January-March 2026. This quarter, every one of those nine has rolled off and been replaced by nine new converts with later maturities (May 2026 through December 2027) — Affirm, a new Marriott Vacations note, JBT Marel, Penn Entertainment, Q2 Holdings, Pebblebrook Hotel, Ziff Davis, plus straight equity in AbbVie, Public Storage, and SLB. That's the defining behavior of a convertible-bond ladder hitting its maturity wall, not a change in conviction. On the equity side, NVIDIA saw a genuine 72.6% share increase, while Amazon was cut a real 23.0%.
