Lending focused on growth-oriented lower middle market businesses

Experienced, long-tenured leadership and investment team

Proprietary sourcing and execution model with high degree of selectivity

Diversified portfolio of largely senior first lien loans to PE backed companies

Active portfolio management and risk monitoring

Equity like origination, underwriting and investment management to optimize investment results and team incentives aligned with shareholders

Background:

Founded in 2001 with the purpose of making loans to lower middle market U.S. businesses, Gladstone Capital's investment team is exclusively focused on this segment of the private capital market

Gladstone Capital is funded through publicly traded common stock (Nasdaq: GLAD) and is leveraged via capital markets including unsecured senior note issues, private preferred stock issue and a bank revolving credit facility

Managed by Gladstone Management Corporation, an SEC registered investment adviser managing $4.0+ billion in assets across four publicly traded yield-oriented funds

Investment Strategy:

Target direct originated secured debt investments in growth-oriented companies with revenue visibility and free cash flow to support organic deleveraging and where capital structure flexibility and lender support are valued

Target companies with operating cash flow (EBITDA) of $3-25 million and investments of $8-40 million, typically below the minimum investment threshold of most large-scale private capital funds

Majority of investments are backed by private equity sponsors (~82% of the portfolio at 03/31/26), which provide governance oversight, strategic sector insight, experience managing leveraged capital structures and access to additional investment capacity to support growth

Deal Sourcing/Diligence/Risk Management:

Leverage experienced origination team to source, structure, undertake "equity level" diligence and agent loans to control lender protections including financial maintenance covenants and remedies

Highly selective screening process where under 5% of deals reviewed ultimately close and commit senior investment resources to pro-actively manage investments via ongoing board level participation to mitigate credit losses

All investments undergo ongoing senior management review, quarterly third-party expert investment valuations in support of SEC filed financials which are subject to quarterly oversight by Gladstone Capital's audit committee and independent board members

Why focus on lower middle market ("LMM") companies

Greater industry diversity and more consistent flow of growth-oriented investment opportunities as founder or family businesses seek liquidity and PE firms attracted by the opportunity to professionalize and scale these businesses to generate equity appreciation

Lower cash flow purchase multiples in the LMM translate to reduced financial leverage, better asset collateral coverage, and the ability for lenders to structure and deliver a complete debt financing solution

Smaller investment threshold attracts less competition from larger private debt funds or commercial banks, supporting more attractive investment returns at lower relative leverage levels, often with lender-friendly documentation protections

LMM companies and PE Sponsors are more receptive to equity co-investments, offering opportunities to selectively participate in anticipated growth and equity appreciation

Proprietary origination and lead lender solution approach provide elevated diligence insight and management team access, leading to greater visibility and influence over strategy & risk mitigation

Trends Enhancing Opportunity for Non-Bank/Private Credit Lenders

PE Sponsors looking to scale LMM platform investments rely upon flexible financing solutions, often with limited amortization or requiring future funding commitments, which demand a more experienced and responsive lender capable of underwriting long-term equity strategies and agility to respond to changing conditions and new opportunities

Providing streamlined "one-stop" financing solutions accelerates transaction closings and simplifies future growth funding or facility modifications for the borrower

Shifting capital market conditions, regulatory or centralized credit controls or limited depth of commercial lending resources hamper commercial bank participation as cashflow lenders to the LMM PE sponsor community

Private Credit market increasingly concentrated by multi-billion-dollar firms prioritizing larger borrowers (>$25 million EBITDA) to align their investment capabilities with institutional capital deployment objectives and lower-fee structures

Page 6

LMM is a less competitive segment of the private credit market, offering a more attractive risk reward profile that aligns well with the flexibility of Gladstone Capital's non-bank investment platform

Originations/Portfolio Activity:

New investments totaled $43.6 million during the quarter and included three new PE Sponsored investments in the manufacturing and environmental services sectors.

Portfolio exits, amortization payments, and prepayments were $46.3 million and the fair value of the portfolio increased quarter-over-quarter due to asset appreciation.

Healthcare industry concentration declined and is expected to fall further with pending exits; notable uptick in precision manufacturing businesses related to aerospace and defense and domestic sourcing needs and no software exposure.

Portfolio Yield / Net Investment Income (NII):

Interest income for the period declined 2.9%, or $0.7 million quarter-over-quarter to $23.2 million as average earning assets rose 2.8%; however, the weighted average portfolio yield fell 40bps to 11.8% with lower average SOFR rates.

Total investment income rose by $1.5 million (6.0%) to $26.0 million, driven largely by $2.2 million higher other investment income, comprised of a $0.9 million prepayment fee and a $1.8 million dividend from an equity investment.

Total expenses rose by $0.9 million, with interest expenses declining $0.1 million, and net management fees increasing $0.9 million on reduced closing fee credits.

Net investment income for the quarter was $11.8 million or $0.52 per share and fully covered the $0.45 cash distributions.

Portfolio Performance and Valuation:

Our portfolio continues to perform well with modest leverage metrics and favorable liquidity. We ended the quarter with three non-earning debt investments (flat from prior quarter) representing 1.6% of debt investments at fair value.

Maintained our conservative asset mix with 90.0% of investments in secured loans, 70% in lower risk 1st lien loans and weighted average leverage across core proprietary loan portfolio of 4.0x.

PIK income for the quarter declined to $1.7 million or 7.4% of interest income.

Net realized losses were $0.6 million, however, unrealized gains rose to $4.8 million for the quarter, primarily concentrated in 3 positions.

Gladstone Capital Quarterly Net Investment

Despite buyout financing market volatility and significant repayment activity, LMM deal flow over the past year have lifted earning assets by $144 million or 18.9%.

Strong deal flow and healthy backlog of new investments are key to negate competitive pressures on spreads, leverage levers or the erosion of lender financing protections.

1st lien investments were 70% of the portfolio driven by recent debt position repayments.

87% of our loan portfolio is subject to floating rates with minimum SOFR floors.

We continue to make minority equity co-investments in approximately half of our new originations to selectively capitalize on the most attractive buyout opportunities.

The current portfolio valuation of $906.8 million represents 98.0% of cost as of 03/31/2026.

Capital Base and Liquidity

Total Assets increased to $925 million as of March 31, 2026, consisting of ~$907 million in investments at fair value and ~$18 million in cash and other assets.

Maintained a conservative debt level at 84.3% of NAV, well below the BDC industry average of 125.6%.

Liabilities decreased to $407 million as of March 31, 2026 (down from $416 million).

Average financing cost of 5.84% as of quarter-end with 47% at floating rates and next debt maturity of $50 million due in May 2027.

Revolving line borrowings decreased to $200 million, with additional line borrowing availability of >$150 million.

ROE Performance

Portfolio growth and performance, relatively stable investment margins and stable valuations contributed to ROE of 8.45% for LTM Mar-26 period (9.6% NII ROE).

Strong net interest income contributed to NII of $0.52 and covered monthly distributions of

$0.15 per common share ($1.80 per annum).

Reduced competitive pressures on lending spreads, the consensus expectation of fewer Fed rate cuts and continuation of our modest net asset growth are all supportive of our near-term earnings and distribution coverage.
