Insights

CFO change with immediate replacement, no disputes disclosed; governance impact appears neutral.

The Company disclosed the resignation of its CFO, Thomas Sweeney, effective October 29, 2025, with no disagreements cited. The Board appointed George A. Martinez as Chief Financial Officer and principal accounting and financial officer, effective immediately. He serves within Oaktree’s finance organization and previously held audit leadership roles at Ernst & Young; he is a CPA.

Mr. Martinez will not be compensated by the Company and has no employment agreement. He is expected to enter into standard Indemnity and Letter Agreements on terms consistent with existing directors and officers. No related‑party transactions or family relationships were disclosed.

This signals continuity in financial leadership while minimizing incremental cost. The immediate designation of a new principal accounting and financial officer helps reduce disruption risk around reporting. Items to watch include timely execution of the indemnity and letter agreements, any future changes to his compensation status, and the Company’s next periodic report for confirmation of smooth transition in financial reporting controls after October 29, 2025.
