Worker Solutions : Third Party Solution Provider Engagement Snapshot[1] Lafayette Square currently does not receive any compensation for the recommendation to use Third Party Solution Providers. However, we may offer portfolio companies a small stepdown on financing costs if they engage a Third Party Solution Provider and/or adopt certain other designations (such as B-Corporation status) or human capital advice, and in some cases, will negotiate discounts for them on the services provided by Third Party Solution Providers. [1] Data as of June 30, 2024, and provided by Third Party Solution Provider and not part of the data Lafayette Square receives directly from its portfolio companies. This data reflects loans for which employees made payments during Q2 2024. [2] This testimonial was provided by a portfolio company employee to a Third Party Solution Provider as part of a non-compensated, optional, feedback form. $1,964 in zero-interest loans to portfolio company workers to manage their cash flow and avoid taking on high-interest debt in quarter ended June 30, 2024. The top three purposes cited by portfolio company workers this reporting period for using no-cost assistance were: • Other Expenses • High-Interest Debt • Emergency Cash “Third Party Solution Provider is helping me pay unexpected vet bills! I’d like to thank my HR team for this new option we have. It’s really helped me in hard times.” -Employee[2] 10 ®
