Ares Capital Corporation’s ARCC total investment income has shown an overall upward bias over the last few years, although the trend has not been consistently positive on a quarter-to-quarter basis. While the metric declined in 2020, it saw a five-year (2019-2024) compound annual growth rate (CAGR) of 14.4%, with the uptrend continuing in the first nine months of 2025.
Growth was primarily driven by a rise in demand for personalized financing solutions, which boosted investment income. Moreover, ARCC has been benefiting from a large and diversified investment portfolio, steady deployment of capital into middle-market loans and a healthy investment backlog.
In 2024, 2023, 2022, 2021, 2020 and 2019, the company originated $15.1 billion, $6 billion, $9.9 billion, $15.6 billion, $6.7 billion and $7.3 billion, respectively, in gross investment commitments to new and existing portfolio companies. In the first nine months of 2025, the company originated $10 billion of gross investment commitments.
As of Sept. 30, 2025, Ares Capital had total investments (fair value) of $28.7 billion, of which 23.2% was in software & services, and 11.9% in healthcare equipment & services. Other major investment areas were commercial & professional services (11.4%), financial services (10.5%), and insurance services (5.9%).
Going forward, a few headwinds could limit the pace or consistency of investment income growth. Changes in interest rates, competitive pressures and periodic declines in fee income could weigh on total investment income in 2026 to some extent. However, given the regulatory changes and consistently rising demand for customized financing, ARCC is expected to witness an overall increase in total investment income this year. The company’s focus on predominantly floating-rate assets positions it to generate solid income in a high-rate environment, while diversification across industries and income sources, including structuring and other fee income, helps stabilize revenues over time.
