Portfolio Valuations Independently Validated & Consistently Realized Broad Third-Party Review1 Backtesting Demonstrates Accuracy2,3 Third-party review, backtesting consistency, and internal independence support the reliability of our fair value marks. Fair value marks tracked exit values within 0.2%-2.4% over the year preceding exit. 1. Independent ownership: Portfolio Monitoring & Valuation owns the valuation process and develops fair value marks independently, with no input from originators on valuation conclusions. 2. Targeted third-party review: Independent valuation coverage is governed by a structured framework that considers position size, risk rating, and other relevant factors, with the objective of prioritizing larger exposures and riskier credits where valuation judgment is most meaningful.

Validated by back-testing: Historical debt exits are reviewed against prior valuation marks, and results have supported the reasonableness and consistency of Runway’s valuation framework. 4.
