25 ImportantInformation This presentation should be read in conjunction with the BDC's Form 10-Q which was filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 2025, which summarizes certain financial and performance information for the quarter ended March 31, 2025. [1] “Working-Class Areas” refers to: i)“Empowerment Zones”, as defined in the Empowerment Zones and Enterprise Communities Act of 1993, as amended; ii)“Opportunity Zones”, as defined in the U.S. Tax Cut and Jobs Act of 2017, and/or areas targeted by a government entity for redevelopment or to revitalize or stabilize designated disaster areas; and iii) low- and moderate- income (“LMI”) areas, as defined under applicable CRA regulation as an individual income that is less than 80% of the area median income (“AMI”) or a median family income that is less than 80% in a census tract. AMI is defined as the median family income for the metropolitan statistical area or metropolitan division, if applicable, or if the person or census tract is located outside of a metropolitan statistical area, the statewide non-metropolitan median family income. We may use the terms "LMI", "underserved" and “Working-Class" interchangeably. [2] National turnover includes private employee data from the U.S. Bureau of Labor Statistics -Job Openings and Labor Turnover Survey for calendar year 2024. Data was extracted as of February 18, 2025. [3] PYMNTS &Lending Club, February 2025. [4] National private sector retirement benefits participation data is sourced from the U.S. Bureau of Labor Statistics – March 2024 National Compensation Survey. “Lower wage workers” refers to those earning less than 25% of average wages. [5] Lafayette Square analysis of U.S. Securities and Exchange Commission's Electronic Data Gathering, Analysis, and Retrieval (EDGAR) database of BDC portfolio companies as of Q3 2024 and Dun and Bradstreet Data as of February 2025. The Federal Financial Institutions Examination Council's (FFIEC) defines middle to upper income as median family incomes making greater than 80% of the area median income. Middle market is defined as firms with revenue between $10 million and $1 billion. [6] Lafayette Square analysis of U.S. Securities and Exchange Commission's Electronic Data Gathering, Analysis, and Retrieval (EDGAR) database of BDC portfolio companies as of Q3 2024. Overlap (or cross investments) is for all public and private BDCs. [7] Portfolio company employment metrics shown are comprised of (1) KPI quarterly reporting data from 16 of 42 portfolio companies as of March 31, 2025; and (2) data collected as of the BDC’s initial investment for the remaining portfolio companies who did not agree to provide quarterly census data. Corresponding employee metrics rely on feedback from our portfolio companies, the accuracy of which cannot be guaranteed and may be calculated differently by each company. [8] Change Since Initial Investment Average is taken as the average of all portfolio companies' change in turnover, medical care participation or retirement participation since the BDC's initial investment, otherwise known as deal close date, with the portfolio company. Where data wasn't available in the same quarter as the initial investment, the next available quarter's data was used. Percentages are based on 16 of 42 portfolio companies’ current human capital data made available to Lafayette Square. [9] Lafayette Square’s 2030 goals to (1) increase employment opportunities (by helping businesses create and/or retain 100,000 Working-Class jobs, and 150,000 jobs overall), (2) provide significant managerial assistance to small and middle-market companies (by incentivizing at least 50% of our borrowers to adopt Worker Solutions®) and (3) encourage economic growth in Working-Class communities (by investing at least 50% of our portfolio in borrowers who are either located in Working-Class communities or are substantial employers of Working-Class people.) [10] Lafayette Square seeks to improve the retention, well-being, and productivity of employees by connecting portfolio companies with third-party service providers that deliver workplace benefits and/or advisory support ("Third-Party Solution Providers") through Lafayette Square’s affiliated “Worker Solutions®” platform. Worker Solutions® inputs represents results from services offered by 4 of 7 Third-Party Solutions Providers adopted by Lafayette Square portfolio companies and HR policy changes implemented by portfolio companies. Please note that metrics regarding the use of the following Third-Party Service Providers have not been included: (i) Vault, due to services having not yet been utilized by workers; and (ii) Esusu, as services are currently offered only to an affiliated project of a Lafayette Square portfolio company and not to employees of the portfolio company. [11] Cumulative savings through Third-Party Solution Provider, Sunny Day Fund, represents 197 total workers across three portfolio companies. 2,567 total workers, across three portfolio companies have access to the service.

26 Important Information [12] Cumulative debt prevented through Third-Party Solution Provider, HoneyBee, from 146 total workers across two portfolio companies and 1,633 total workers with access to the service. Savings relative to high-cost lending products calculated by using the average payday loan APR (~400%), average loan amount of $213, and an assumed 5-month repayment period (the average time it takes to repay payday loans). https://www.incharge.org/debt-relief/how-payday-loans-work/ [13] HR changes were implemented by three portfolio companies, resulting in 2,223 total workers now with access to services resulting from these policy changes. [14] 45 total workers have signed up for credit building services via rent reporting through Third-Party Solution Provider, Boom, with 555 total workers having access to these services in one portfolio company. Credit building metrics from Esusu are not included, as services are currently offered only to an affiliated project of a Lafayette Square portfolio company and not to employees of the portfolio company. [15] 7 total workers of one portfolio company have participated in 48 1:1 financial coaching sessions through TrustPlus, a Third-Party Solution Provider. 88 total workers at the portfolio company have access to the service. [16] On March 25, 2025, the Board of Directors of the BDC declared a regular distribution to stockholders in the amount of $0.28 per share and a supplemental distribution in the amount of $0.07 per share. In the aggregate, the regular distribution and supplemental distribution represents an annualized distribution rate of approximately 9.5% [17] Lafayette Square rewards portfolio companies with an interest rate stepdown when they adopt services from Third-Party Solution Providers and/or implement policy changes to existing workplace benefits (defined as “Qualifying Human Capital Investments”) that we believe will enhance employee well-being and improve retention. As of March 31, 2025, we have rewarded a combined total of $192,486 through interest rate step down savings. Lafayette Square portfolio companies having adopted Qualifying Human Capital Investments have received a total of $299,498 in cumulative savings through interest rate step downs from the BDC in addition to other sources, including the Private Fund and other non-Lafayette Square lenders. [18] Weighed Average Yield is only one component of expected performance and is not and should not be viewed as a statement of the future performance of the BDC. Past performance is not indicative of future results. Yield of Assets in the portfolio is not indicative of the return or distribution rate received by investors. [19] Portfolio company employment metrics shown are comprised of 1) KPI quarterly reporting data from 16 of 42 portfolio companies as of March 31, 2025; and 2) data collected as of the BDC’s initial investment for the remaining portfolio companies who did not agree to provide quarterly census data. Corresponding employee metrics rely on feedback from our portfolio companies, the accuracy of which cannot be guaranteed and may be calculated differently by each company. [20] National median income data is from the U.S. Census Bureau - 2022 American Community Survey. This is the most recent data available as of March 2025. Median family income is used to calculate individual LMI per CRA guidelines. The metric is included at the national level to serve as a similar, but not exact, comparison. [21] Turnover rates are calculated by dividing the total terminations, voluntary and involuntary, for the period by the average number of employees who worked during or received pay for the same period. National turnover includes private employee data from the U.S. Bureau of Labor Statistics -Job Openings and Labor Turnover Survey for calendar year 2025. Data was extracted as of May 2, 2025. [22] Medical Care Benefits are plans that provide services or payments for services rendered in the hospital or by a qualified medical care provider. Participation is calculated from the unrounded percentage of workers who participate in the plan. 628 employees from portfolio companies who did not provide medical care benefits data to the Company were not included in this calculation. National private sector medical care and retirement benefits participation data are sourced from the U.S. Bureau of Labor Statistics – March 2024 National Compensation Survey. [23] Retirement Benefit plans includes defined benefit pension plans and defined contribution retirement plans. Participation is calculated from the unrounded percentage of workers who participate in the plan. National private sector medical care and retirement benefits participation data are sourced from the U.S. Bureau of Labor Statistics – March 2024 National Compensation Survey.
