What Happened
Diameter Credit Co. filed an 8-K on July 31, 2026 (Item 5.02) reporting that trustee Daniel Kasell resigned effective July 29, 2026. On July 30, 2026 the Board appointed Daniel Gish, age 42, as an independent trustee, effective immediately. Mr. Gish also joins the Board’s Nominating and Governance Committee and Audit Committee. In connection with Mr. Kasell’s resignation, Steven Bossi was appointed Chairman of the Audit Committee, effective immediately.

Key Details

• Resignation: Daniel Kasell resigned from the Board and all committees, effective July 29, 2026; no disagreement with the company or its adviser was reported.
• Appointment: Daniel Gish appointed as independent trustee on July 30, 2026; will serve on the Nominating & Governance and Audit Committees.
• Background: Mr. Gish was a Portfolio Manager at Marshall Wace (managed long/short investment grade credit, 2024–2026), previously at Verition Fund Management LLC and UBS AG; B.A. in Economics, Middlebury College (2005).

Why It Matters
This is a governance change that affects board composition and committee leadership—particularly oversight of financial reporting and risk (Audit Committee). The filing reports an orderly transition with no disclosed disagreements or special compensation tied to the appointment, and it does not report any immediate financial impact. Investors monitoring board independence, audit oversight, or governance practices should note the new independent trustee and the Audit Committee chair change.
